Further, another foot 84 is provided in consideration of the balance of the calculator main body 82. When the calculator main body 82 is removed from the cover 71, the stand 75 is stored in the stand storage section 72 by the elastic force of the return spring 80.

<Third Embodiment> A portable information device similar to that of the first embodiment will be described as an example of the electronic device of the third embodiment. As shown in FIG. 17, in this portable information device, a cover 86 is rotatably attached to a device main body 85 by a hinge 87. Then, similarly to the first embodiment, the cover 8
6 can be turned back to the back side of the device main body 85, and the back side of the cover 86 is the bottom surface. Also, the cover 86
Is provided with a stand 88.

As shown in FIG. 18, the hinge 87 comprises a hinge frame 89 and a hinge plate 90. The cover 86, the hinge 87, and the stand 88 are rotatably attached by the first hinge pin 91, and the second hinge pin 92, the third
The device main body 85 and the hinge 87 are rotatably attached by the hinge pin 93 of FIG. A stopper 88b is formed on a shaft portion 88a of the stand 88, while a stopper 89b on a shaft portion 89a of the hinge frame 89 is formed. The stand 88 is moved up and down with the rotation of the cover 86 by the stoppers 88b and 89b.

Next, a process in which the stand 88 is turned upside down with the rotation of the cover 86 will be described with reference to FIG. FIG.
9 includes a first cover 86 that covers the operation surface of the device main body 85.
An example of a process in which the cover 86 rotates from the posture to the second posture that covers the back surface opposite to the operation surface of the device main body 85 is shown.

In the movement from the state to the state described above, the cover 86 and the hinge 87 operate integrally without rotating, and rotate by 180 degrees about the hinge axes of the second and third hinge pins 92 and 93. . Therefore, 180 of the hinge 87
Due to the rotation of degrees, the stopper 89b rotates 180 degrees,
The stopper 88b is also rotated 180 by the stopper 89b.
Rotate degrees.

In the movement from the state to the state described above, the hinge 87 does not operate, and only the cover 86 rotates 90 degrees.
Therefore, the stopper 89b does not change its position, and only the stopper 88b rotates 90 degrees.

In the movement from the state to the state, the hinge 87 does not operate similarly to the above, so that the stopper 88b does not rotate by the stopper 89b, and only the cover 86 rotates 90 degrees, so that the stand 88 automatically stands up. It will be.

If the operation reverse to the above is performed, that is, from the second position in which the cover 86 covers the back surface opposite to the operation surface of the device main body 85, the cover 86 covers the operation surface of the device main body 85 in the first position. The stand 88 automatically falls down when it is turned to the posture.

[0032]
