  The best mode for carrying out the present invention is a mode as described in Example 1 below.

  FIGS. 1 and 2 are diagrams showing a configuration and an operation when the portable terminal device according to the first embodiment of the present invention is used as a reading terminal (electronic book terminal) and a portable information terminal (in place of a PDA or notebook personal computer). is there.

  The three thin plates 1a, 1b, and 1c in the upper part of FIG. 1 are adjacent to each other (for example, the thin plates 1a and 1b and the thin plates 1b and 1c) by connecting portions (not shown) such as known hinges. Are connected so that they can be folded and folded. Further, the three thin plates 2a, 2b, 2c in the lower part of FIG. 1 are also connected to each other (for example, the thin plates 2a and 2b, the thin plate 2b, and the like) by connecting means (not shown) such as a known hinge portion. 2c) is foldably and foldably connected.

  In addition, the thin plate group 1 composed of a total of three thin plates 1a, 1b, 1c in the upper part of FIG. 1 and the thin plate group 2 composed of a total of three thin plates 2a, 2b, 2c in the lower part of the figure are hinge portions 3a, 3b. And the hinge part 4 is connected so as to be able to be folded and folded in the vertical direction in the figure.

  As will be described in detail, among the three hinge portions 3a, 3b, 4, the hinge portions 3a, 3b at both ends are arranged such that one of the thin plate group 1 and the thin plate group 2 is in the left-right direction in FIG. When rotating (see FIG. 5B), the connection between the thin plate group 1 and the thin plate group 2 by the hinge portions 3a and 3b can be easily released.

  Further, among the three hinge portions 3a, 3b, 4, the central hinge portion 4 is not only connected to the thin plate group 1 and the thin plate group 2 so that the thin plate group 1 and the thin plate group 2 can be folded and folded in the vertical direction in FIG. One of the group 1 and the thin plate group 2 is also connected so as to be rotatable in the left-right direction in FIG.

  Further, in the first embodiment, one sheet of electronic paper 5 is provided on one surface of the three thin plates 1a, 1b, 1c constituting the thin plate group 1 so as to straddle almost all of them. . Further, in the first embodiment, one sheet of electronic paper 6 is provided on one surface of the three thin plates 2a, 2b, 2c constituting the thin plate group 2 so as to almost entirely cover them. ing.

  Therefore, in this embodiment, as described above, even if the thin plates 1a-2c constituting the thin plate groups 1 and 2 are folded or folded with respect to each other, they are unfolded and opened to the user. Even when these states are shifted to each other, the electronic papers 5 and 6 maintain the performance as a single sheet having a screen display function. Therefore, even when each thin plate is unfolded as shown in FIG. 1 or FIG. 2, the electronic papers 5 and 6 display “one screen” (a screen without “seam due to the presence of a hinge portion”) as a user. Can be provided.

  As shown in FIG. 2A, the first embodiment is opened in the vertical direction when viewed from the user, and the lower surface of the thin plate group 2 is placed on a desk (so that the electronic paper 6 is on the upper surface). The thin plate group 1 may be slightly inclined with respect to the thin plate group 2, and both may be temporarily fixed at this angle (temporarily fixed by a known tilt mechanism or friction mechanism). In this case, the thin plate group 2 installed on the desk functions as a touch panel (for example, a soft keyboard is displayed on the screen or a handwriting input recognition screen is displayed), and data can be input with a fingertip or a pen. (The touch panel method can be various methods such as a method of detecting pressing force using a piezoelectric element, a method of detecting a change in capacitance, and a method of detecting the position of a pen tip or a fingertip with infrared rays.
