Description

  The present invention relates to a portable information terminal.

  In a conventional portable information terminal of this type, for example, a cellular phone, a technique for changing the display unit from portrait display to landscape display is disclosed in, for example, Japanese Patent Application Laid-Open No. 2003-319043 (Patent Document 1). FIG. 57 is a schematic front view showing the configuration of the mobile phone disclosed in the above publication. Referring to FIG. 57, this mobile phone 510 has a lower unit 501, an upper unit 502 and a hinge portion 503. The lower unit 501 and the upper unit 502 are connected via a hinge portion 503 so as to be foldable. The lower unit 501 has an operation unit 511 including various keys. The upper unit 502 includes a display unit 502a having a display unit 521 and a support unit 502b that rotatably supports the display unit 502a.

  The cellular phone 510 is opened by rotating the upper unit 502 relative to the lower unit 501 around the hinge portion 503 from a state (not shown) in which the lower unit 501 and the upper unit 502 are folded. (Fig. 57 (a)). In this state, the display unit 521 is in a vertically long display. By rotating the display unit 502a with respect to the support unit 502b from this open state (FIG. 57A), the display unit 521 can be displayed in landscape orientation (FIGS. 57B to 57D). ).

JP 2003-319043 A

  In the mobile phone 510 disclosed in the above publication, two rotational operations are required to bring the display unit 521 into the horizontally long display state from the state in which the lower unit 501 and the upper unit 502 are folded. . That is, an operation of rotating the upper unit 502 with respect to the lower unit 501 and an operation of rotating the display unit 502a with respect to the support unit 502b are required. For this reason, there existed a problem that operation became complicated.

  The operator holds the lower unit 501 in the open state (FIG. 57A), while the display unit 502a is rotatably supported by the support unit 502b. For this reason, when the operator tries to rotate the display unit 502a with the hand holding the lower unit 501 so that the display unit 502a is displayed in landscape orientation, it is necessary to extend the gripping finger toward the support unit 502b. is there. At this time, since it is difficult to extend the finger to such an extent that the display unit 502a is rotated by 90 °, the operator cannot complete the transition operation to the landscape display by one operation. For this reason, there is also a problem that the operation for shifting to the landscape display cannot be performed with one hand and the operation is complicated.

  An object of the present invention is to provide a portable information terminal that can be easily operated with one hand from a closed state to an open state.

  One portable information terminal of the present invention includes a first housing, a second housing, and a rotation coupling mechanism. The first housing has an operation unit.

The second housing has a display portion. The rotation coupling mechanism couples the first housing and the second housing so that the second housing rotates relative to the first housing by 90 degrees or less. When the length of the short side of the second casing is a and the length of the long side is b, the rotation center of the rotation coupling mechanism of the first casing is at an angle of 45 ° with respect to the long side. Arranged on intersecting virtual lines. The center of rotation of the rotation coupling mechanism of the second casing is separated from each corner of the second casing by a distance x determined by the equation x = (ba) / 2 along each long side. It is disposed on an imaginary line that passes through the point and intersects the long side of the second casing at an angle of 45 °.

  Still another portable information terminal according to the present invention includes a first casing, a second casing, and a rotation coupling mechanism. The first housing has an operation unit. The second housing has a display portion. The rotation coupling mechanism couples the first casing and the second casing so that the second casing slides and rotates relative to the first casing. The rotation coupling mechanism is configured such that the second casing is in a closed state in which the operation section of the first casing is closed or in a state in which the operation section in which the second casing is covered is exposed. It is comprised so that it can transfer to a state of 90 with a rotation of 90 degree | times. When the length of the short side of the second casing is a and the length of the long side is b, the rotation center of the rotation coupling mechanism of the first casing is set to each corner from the corner of the first casing. Along the long side, it passes through a point separated by a distance x determined by the equation x = (b−a) / 2, and is arranged on a virtual line that intersects the long side at an angle of 45 °. The rotation center of the rotation coupling mechanism of the second casing is disposed on an imaginary line that intersects the long side of the second casing at an angle of 45 °.

  Still another portable information terminal according to the present invention includes a first casing, a second casing, and a rotation coupling mechanism. The first housing has an operation unit. The second housing has a display portion. The rotation coupling mechanism couples the first casing and the second casing so that the second casing slides and rotates relative to the first casing.

  Hereinafter, a case where an embodiment of the present invention is implemented in a mobile phone will be described with reference to the drawings.

(Embodiment 1)
1A is a front view showing a closed state of the portable information terminal according to Embodiment 1 of the present invention, and FIG. 1B is a front view showing an opened state. Referring to FIG. 1, portable information terminal 10 according to the present embodiment includes a first housing 1, a second housing 2, and a rotary connection mechanism 3.

  The 1st housing | casing 1 has an operation part (not shown) on the surface. The 2nd housing | casing 2 has a display part (not shown) on the surface. The first casing 1 and the second casing 2 are directly connected by the rotary connecting mechanism 3 so that the front surface of the first casing 1 and the back surface of the second casing 2 face each other. By the rotation coupling mechanism 3, the back surface (the surface opposite to the surface having the display unit) of the second housing 2 slides relative to the surface of the first housing 1 (the surface having the operation unit). It can be rotated.

  The rotary coupling mechanism 3 includes a closed state (FIG. 1A) in which the second casing 2 covers the entire operation unit of the first casing 1, and the second casing 2 exposes the operation unit. It is possible to shift from one state of the opened state (FIG. 1B) that is bilaterally symmetrical with respect to the center line CC of the first housing 1 to the other state by one rotation operation. It is configured.

  For example, the first casing 1 and the second casing 2 have the same rectangular shape, the length of each short side of the first and second casings 1 and 2 is a, When the length is b, it is obtained from each corner E (intersection of the short side A and the long side B) of the first and second casings 1 and 2 by the equation x = (b−a) / 2. To a point on a virtual line DD (for example, any one of points P1 to P3) passing through a point on each long side B separated by a distance x and intersecting the long side B at an angle of 45 ° The rotation center of the rotation coupling mechanism 3 is arranged.

  When the rotation center of the rotation coupling mechanism 3 is arranged at a point P1 on each long side B of the first and second casings 1 and 2, it is in an open state as shown in FIG. When it is arranged at the point P2 inside the casings 1 and 2 from the side B, it is in an open state as shown in FIG. 2, and it is arranged at the point P3 outside the casings 1 and 2 from the long side B. In this case, an open state as shown in FIG. 3 is obtained.

  In such an open state, the front shape formed of the first and second housings 1 and 2 is preferably “T” -shaped.

  The imaginary line DD is inclined with respect to the side B so as to intersect either the opposite side of the side A or the opposite side of the side B as shown in FIG. is doing.

Next, the opening / closing operation of the portable information terminal of this embodiment will be described.
Referring to FIG. 1, first, in the closed state (FIG. 1A), the second casing 2 covers the entire operation unit of the first casing 1 as described above. From this state, the second housing 2 is slid and rotated, for example, clockwise in the figure with respect to the first housing 1 around the rotation center of the rotary coupling mechanism 3. As a result, the second housing 2 gradually shifts with respect to the first housing 1. By rotating the second housing 2 by 90 ° with respect to the first housing 1, the second housing 2 exposes the operation unit and the center line C-C of the first housing 1 is exposed. The mobile information terminal 10 is in an open state with an outer shape of “T” shape.

  Further, the operation from the open state to the closed state is performed by rotating the second casing 2 in the opposite direction (counterclockwise direction) to the above.

  In this specification, “slide rotation” refers to the opposing surfaces of the first housing 1 and the second housing 2 (that is, the front surface of the first housing 1 and the back surface of the second housing 2). This means that the second casing 2 is rotated with respect to the first casing in a plane parallel to the first casing.

  Moreover, although the case where the 2nd housing | casing 2 was rotated 90 degrees with respect to the 1st housing | casing 1 was demonstrated, you may be comprised so that it may rotate 90 degrees or more. In this case, it is preferable to be configured so that positioning can be performed in a closed state and an open state. For example, a concave portion is provided in the rotating portion, and in a closed state and an open state, a convex member (for example, a sphere) is urged by a spring to fit into the concave portion, and positioning is performed according to the configuration. May be performed.

  Moreover, although the case where the 2nd housing | casing 2 was rotated clockwise from the closed state was demonstrated, you may rotate counterclockwise.

  According to the present embodiment, since the rotation center of the rotation coupling mechanism 3 is arranged on the imaginary line DD, in the opened state as shown in FIG. 1 (a), FIG. 2, and FIG. The second casing 2 can expose the operation unit and be symmetric with respect to the center line CC of the first casing 1.

  Moreover, since it becomes left-right symmetrical, it becomes easy to see a display part by holding | griping the 1st housing | casing 1 in the state where the operator opened. In particular, when a game is played on the portable information terminal 10, the operability of the game by the operator is improved if the display unit is symmetrical with respect to the center line CC of the first housing 1.

  Moreover, since it becomes left-right symmetric, the weight distribution of the portable information terminal 10 in the opened state can be easily made symmetric. Thereby, it is possible to prevent the mobile information terminal 10 from being tilted to the right or left in the opened state. For this reason, even when the operator holds the first casing 1 in an open state, it is easy to prevent the portable information terminal 10 from being tilted. Thereby, even in an unstable state such as in a commuter train, the display unit can be seen stably.

  In addition, by gripping the first casing 1 in the opened state, the portable information terminal 10 can be securely held without hiding the display portion of the second casing 2 with a finger.

  In addition, since it is possible to shift from one of the closed state and the open state to the other state by a single rotation operation, the transition to the open state (horizontal display) is facilitated.

  Further, since the first casing 1 has the operation unit on the surface, the operator can operate the operation unit of the first casing 1 while holding the first casing 1 with one hand. In addition, since the second casing 2 is connected to the first casing 1 held by the operator, the operator opens the second casing 2 only by slightly extending the finger of the holding hand. It is possible to make a transition to a state in which the transition is performed with one hand. Thereby, it is possible to perform all of a series of operations including an operation of opening the portable information terminal 10, a key operation, and a closing operation with one hand.

  In an unstable state, the user can watch the TV (television broadcast) by holding the first casing 1 firmly as a grip in the open state, and in a stable state, the user can watch the TV in a compact closed state. Can do.
