Abstract

A main device includes fixing portions that fix a holding device to one principal surface thereof and project from the one principal surface. An extension device includes a placement portion on which the main device is placed and a wall portion on which the placement portion is provided in a standing manner. The wall portion that faces the one principal surface, to which the holding device is fixed, in a parallel relation, has such a shape as to not interfere with the fixing portions that fix the holding device of the main device, when the main device is placed on the placement portion. The main device can be mounted on the extension device with the holding device mounted thereon, and time and effort to remove the holding device can be saved when the main device is mounted on the extension device.

Claims

1. An extension device onto which/from which a main device can be mounted/dismounted, the main device having a holding device fixed to a principal surface thereof, wherein

the main device comprises fixing portions that fix the holding device to the one principal surface and project from the one principal surface,

the extension device comprises a placement portion on which the main device is placed and a wall portion on which the placement portion is provided in a standing manner, and

the wall portion is configured to face the one principal surface in a parallel relation and not interfere with the fixing portions when the main device is placed on the placement portion.

2. The extension device according to claim 1, wherein

when the main device is placed on the placement portion, another principal surface of the main device adjacent to the one principal surface comes into contact with the placement portion, and

the height of the wall portion from the placement portion is lower than the height from the other principal surface of the main device to the fixing portions for the holding device.

3. The extension device according to claim 1, wherein

the holding device comprises a first holding member fixed to the one principal surface by a pair of the fixing portions and a second holding member fixed to a third surface that faces the other principal surface across the one principal surface, and

the first holding member and the second holding member are connected to each other via a connection member.

4. The extension device according to claim 1, wherein when the main device is placed on the placement portion, the width of the wall portion in a direction parallel to a line of intersection of the placement portion and the wall portion is set so as to be equal to or less than the width between the fixing portions.

5. The extension device according to claim 1, wherein the holding device rotates at a pair of the fixing portions.

6. An information processing system including a main device and an extension device onto which/from which the main device can be mounted/dismounted, wherein

the main device comprises:

a housing in which an electronic component that performs information processing is provided; and

a holding device fixed by fixing portions projecting from one principal surface of the housing,

the extension device comprises;

a placement portion on which the main device is placed; and

a wall portion on which the placement portion is provided in a standing manner, and

the wall portion is configured to face the one principal surface in a parallel relation and not interfere with the fixing portions when the main device is placed on the placement portion.

7. The information processing system according to claim 6, wherein

when the main device is placed on the placement portion, another principal surface of the main device adjacent to the one principal surface comes into contact with the placement portion, and

the height of the wall portion from the placement portion is lower than the height from the other principal surface of the main device to the fixing portions for the holding device.

8. The information processing system according to claim 6, wherein

the holding device comprises a first holding member fixed to the one principal surface by a pair of the fixing portions and a second holding member fixed to a third surface that faces the other principal surface across the one principal surface, and

the first holding member and the second holding member are connected to each other via a connection member.

9. The information processing system according to claim 6, wherein when the main device is placed on the placement portion, the width of the wall portion in a direction parallel to a line of intersection of the placement portion and the wall portion is set so as to be equal to or less than the width between the fixing portions.

10. The information processing system according to claim 6, wherein the holding device rotates at a pair of the fixing portions.
