REMOVABLE DEVICE AND IMAGE FORMING APPARATUS

摘要

A removable device is removably attachable to an image forming apparatus main body. The removable device includes an information storage device, a holder, and a low frictional structure. The information storage device includes: an information storage unit that stores information to be communicated between the apparatus main body and the removable device; a terminal to be contacted with an apparatus main-body terminal, for communicating information with the apparatus main body; and a substrate that holds the information storage unit and the terminal and that includes a guide to be fitted to a protrusion provided on the apparatus main body. The holder holds the substrate such that the substrate can move, when the removable device approaches the apparatus main-body terminal, on a virtual plane intersecting with a moving direction of the removable device. The low frictional structure is arranged on a contact area between the substrate and the holder.

1. A removable device, removably attachable to an image forming apparatus, the removable device comprising:
an information storage device including:
an information storage unit that stores therein information to be communicated between the image forming apparatus and the removable device;a terminal to be contacted with an apparatus terminal provided on the image forming apparatus, for communicating information with the image forming apparatus; anda substrate that holds the information storage unit and the terminal and that includes a guide to be fitted to a protrusion provided on the image forming apparatus; a holder that holds the substrate of the information storage device such that the substrate is able to move, when the removable device approaches the apparatus terminal provided on the image forming apparatus, on a virtual plane intersecting with a moving direction of the removable device; and a low frictional structure arranged on a contact area between the substrate and the holder.
