  In such a configuration, the claw 23a of the engagement piece 23 is engaged with the stay 12 in the state shown by the solid line in FIG. 1 and the state shown in FIG. 3 in which the stand member 9 is superimposed on the bottom 2a of the lower case 2. Therefore, the rotation of the stand member 9 around the pivot 11 is restricted. At the same time, in the stand member 9, the side portions of the leg portions 10A and 10B are engaged with the first movement restricting member 25 and the first movement restricting portions 26b and 26b of the first rotation restricting members 26A and 26B. Therefore, movement in the direction of arrow AB is regulated. Thus, in addition to the function of restricting the rotation of the stand member 9, the first rotation restricting members 26A and 26B have a function of restricting the movement of the stand member 9 in the arrow AB direction. Therefore, since it is not necessary to provide a dedicated movement restricting portion on the bottom portion 2a of the lower case 2, the structure of the bottom portion 2a can be simplified and the outer dimension of the bottom portion 2a can be reduced.

By engaging with 28b, movement in the direction of arrow A is restricted. As described above, the second rotation restricting member 28 has a function of restricting the movement of the stand member 9 in addition to the function of restricting the rotation of the stand member 9, and therefore, the second rotation restricting member 28 is dedicated to the bottom 2 a of the lower case 2. Since there is no need to provide a movement restricting portion, the structure of the bottom portion 2a can be simplified and the outer dimension of the bottom portion 2a can be reduced.

  When the telephone 1 is raised by an angle β, it is checked whether the stand member 9 is positioned at the position indicated by the solid line in FIG. 1, and if it is not positioned, the stand member 9 is moved in the arrow B direction. Then, the stand member 9 is rotated by an angle β about the pivot 11 as a rotation center. By this rotation, the engagement between the leg portions 10A and 10B of the stand member 9 and the first movement restriction portions 26b and 26b of the first rotation restriction members 26A and 26B is released. Therefore, by moving the stand member 9 by a distance L2 in the direction of arrow A as indicated by a two-dot chain line in the drawing, the back surface of the leg portion 10A is moved to the second rotation restricting portion of the second rotation restricting member 28A. 28a is engaged.

  At the same time, the second engaged portions 10d and 10d of the respective leg portions 10A and 10B engage with the second rotation restricting surfaces 29a and 29a of the second rotation restricting convex portions 29A and 29B. As shown in FIG. 5, the member 9 is sandwiched between the second rotation restricting member 28 and the second rotation restricting convex portions 29A and 29B, and is rotated in the clockwise / counterclockwise direction with the pivot 11 as the center of rotation. Is restricted. Accordingly, the second rotation restricting member 28 and the second rotation restricting convex portion 29 form the second turn restricting means 30, and the second turn restricting means 30 and the stand member 9. In cooperation with the telephone 1, the telephone 1 is kept in a state where the angle of the display 7 side from the desk 8 is β. At this time, the movement of the stand member 9 in the direction of the arrow A is restricted when the notch 10b of the leg portion 10B is engaged with the side portion 17b of the second shaft support portion 17.

  As described above, the second shaft support portion 17B has a function of restricting the movement of the stand member 9 in the direction of arrow A in addition to the function of rotatably supporting the pivot 11 of the stand member 9. In addition, since it is not necessary to provide a dedicated movement restricting portion on the bottom portion 2a of the lower case 2, the structure of the bottom portion 2a can be simplified and the outer dimension of the bottom portion 2a can be reduced. Further, by providing two rotation restricting means for restricting the rotation of the stand member 9, the angle at which the telephone 1 is raised from the desk 8 can be selected in accordance with the installation height, installation position, etc. of the telephone 1. Therefore, the operability of the operation panel and the visibility of the display unit can be improved, and the usability is improved.
