[0011]

[Operation] Place the external storage device on the frame so that the screw insertion hole of the external storage device matches the holding portion of the frame, and insert the screw into the screw insertion hole from the front side of the external storage device. Next, the shaft portion of the screw is screwed into the screw hole of the holding portion so as to pass through the fixing portion. By this screwing, the head of the screw is seated on the fixing part, and the external storage device is fixed to the frame holding part via this fixing part. in this case,
It has a simple structure with a small number of parts and does not take up much space, and the screws are hidden in screw insertion holes formed in the external storage device. Furthermore, since the external storage device is somewhat lifted from the frame, it is less susceptible to effects such as frame distortion.

[0012] Because the screw insertion hole is located inside the area for loading media into the external storage device, and because the elastic member is interposed between the fixing part and the holding part,
In addition to improving the appearance, the influence of distortion from the frame can be further suppressed.
