-Summary of the Invention- The present invention relates to a case structure for an electronic device in which a drawer piece is provided on the bottom surface when the case is erected to prevent it from falling over, and the case structure is such that the drawer piece is fitted into a through groove provided in the case and stored. It has a structure in which multiple drawer pieces with different dimensions are pulled out alternately in opposite directions, so that when the electronic equipment is installed in a reclined state, the drawer pieces do not damage the external appearance of the device, and it also prevents the same device from falling over. When electronic devices equipped with devices are installed side by side in an upright position, the drawer piece pulled out from one housing is inserted into the through groove of the adjacent housing,
The housings are more reliably prevented from collapsing, and the housings placed side by side can be installed without gaps and with their relative positions regulated.

-Prior Art- Fig. 9 shows a conventional toppling prevention device for a tabletop electronic device (for example, a floppy disk drive device) having a flat housing. The device can be installed both in the illustrated collapsed state and in the upright state with surface 3 as the bottom surface.Since the width dimension w of the casing is small when the device is installed upright, it can be pulled out to prevent the device from falling down. A pullout piece 51 is provided to prevent this. In the conventional structure, a long hole 52 in the drawing direction is provided in the drawer piece 51, and a screw 53 that passes through the long hole and is screwed into the main body 2 of the case allows the drawer piece to be placed in the stored state and in the pulled out state as shown in the figure. 51 is fixed.

-Problems to be Solved by the Invention- However, in the structure as shown in FIG. Since the drawer pieces 51 on which the devices are to be installed side by side interfere with each other, the drawer pieces on the side where the devices are placed adjacent to each other cannot be pulled out, and the standing state of the devices becomes unstable accordingly. Further, the external appearance of the device when it is laid down is also unsightly, and if the drawer piece 51 is removed, it is troublesome to store it.

This invention provides a more rational mounting structure for the drawer pieces to prevent them from falling over, and even when a plurality of electronic devices are installed closely together, the drawer pieces do not get in the way of each other. It is effective for stably installing equipment upright, prevents mutual movement of equipment placed side by side, and also prevents damage to the external appearance of the equipment even when the drawer pieces are stored and the equipment is installed in a reclined state. The purpose is to obtain structure.
