In the present invention, the elastic force providing mechanism 27 is another such as a mechanism including a variety of elastic members or elastic members capable of applying an elastic force to the slide member 22 to open and close the slide member 22 semi-automatically in the opening and closing direction. It can be changed to elastic means.

Hereinafter, with reference to the accompanying drawings will be described the operation of the sliding device according to an embodiment of the present invention.

When the second body 14 is in the closed position as shown in FIG. 4A, the elastic force of the elastic force providing mechanism 27 is minimized, and the stopper 61 of the slide member 22 is the posture correcting protrusion 41. Is in contact. At this time, even if an unintentional external force is applied to the second body 14 in the opening direction, the slide member 22 does not move easily and keeps the second body 14 closed because of the elastic force of the elastic force providing mechanism 27. The portion overlapping with the fixing member 21 of the slide member 22 may receive the elastic force from the elastic force providing mechanism 27 toward the first guide member 23 minutely. However, since the first posture correcting member 25 of the slide member 22 is in contact with the protruding member 75 coupled to the fixing member 21, the slide member 22 does not lean toward the first guide member 23. The posture parallel to the fixing member 21 is maintained.

As shown in FIG. 4B, when the second body 14 in the closed position is pushed in the opening direction under an external force, the slide member 22 is along the first guide member 23 and the second guide member 24. Sliding in the opening direction. At this time, as the coil spring 83 of the elastic force providing mechanism 27 extends, the elastic force increases in the elastic force providing mechanism 27. When the slide member 22 moves approximately half of the entire moving distance in the opening direction, the elastic force of the elastic force providing mechanism 27 becomes maximum. In this state, when the slide member 22 is biased to the open position, the coil spring 83 is elastically restored and the slide member 22 moves to the open position semi-automatically.

As shown in FIG. 4C, when the slide member 22 slides to the open position and the second body 14 is in the open position, the keypad 13 of the first body 12 is exposed to the outside. When the slide member 22 is in the open position, the coil spring 83 is restored to its original state. At this time, even if an unintended external force is applied to the second body 14 in the closing direction, the slide member 22 does not move easily and maintains the second body 14 in the open state because of the elastic force of the elastic force providing mechanism 27.

On the other hand, when the slide member 22 approaches the open position when the slide member 22 receives the elastic force from the elastic force providing mechanism 27 and moves in the open direction, a pair of posture correction protrusions that are coupled to the fixing member 21 are provided. 41 and 45 enter the pair of posture correcting grooves 58 and 59 formed in the slide member 22. At this time, when the slide member 22 further moves to the open position, the posture correcting protrusions 41 and 45 move in contact with the side portions of the posture correcting grooves 58 and 59, and the center of the posture correcting grooves 58 and 59. Converge to In addition, when the slide member 22 moves to the open position, the second posture correcting member 26 coupled to the slide member 22 contacts the protruding member 75 of the first guide member 23. Therefore, even if the slide member 22 is slidably moved in either state, it is corrected in a posture parallel to the fixing member 21 when it comes to the open position.

When the second body 14 in the open position moves to the closed position, the second body 14 slides semi-automatically by the elastic force of the elastic force providing mechanism 27. At this time, as shown in Fig. 4A, the stopper 61 comes into contact with the posture fixing protrusion 41 disposed on the same straight line so that the slide member 22 stops in the closed position without great impact. The first posture correcting member 25 is in contact with the protruding member 75 so that the slide member 22 maintains the posture parallel to the fixing member 21.

As described above, in the sliding device 20 according to the present invention, the slide member 22 is closed by the first posture correcting member 25 of the slide member 22 contacting the protruding member 75 of the fixing member 21. The posture parallel to the fixing member 21 in the open position by maintaining the posture parallel to the fixing member 21 at the position, and the second posture correcting member 26 contacting the protruding member 75. Keep it. Therefore, almost no distortion flow occurs when the slide member 22 slides in the opening and closing direction, and the occurrence of shaking during the opening and closing operation of the portable device 10 is greatly reduced.

The present invention described above is not limited to the configuration and operation as shown and described. That is, the present invention can be variously changed and modified within the spirit and scope of the claims described.
