ELECTRONIC DEVICE PERFORMING COMMUNICATION AND IMAGE FORMING APPARATUS PROVIDED WITH SAME

摘要

An image forming apparatus includes: a toner container, a reader and writer, and a knock mechanism. To the toner container, an RFID tag is attached. The reader and writer opposes the RFID tag. The knock mechanism has a knock member and a rotor reciprocally moving in an attachment and detachment direction of the toner container. When the knock member has been pressed in conjunction with insertion of the toner container and the rotor in conjunction therewith has moved to the first tip position, the RFID tag is brought to approach the reader and writer to a range in which communication with the reader and writer is enabled, and when the rotor has separated from the first tip position and has moved to a locking position, the RFID tag is out of the range in which the communication with the reader and writer is enabled.

主权项

1. An electronic device comprising:
an attachable and detachable component being attachable and detachable to and from a device body of the electronic device and having a recording medium fitted at a tip side in an insertion direction; a communication section communicating information with the recording medium at a position opposing the recording medium included in the attachable and detachable component fitted to the device body; and a knock mechanism having a knock member and a mover reciprocally moving in an attachment and detachment direction of the attachable and detachable component to and from the device body, wherein the knock member is pressed in conjunction with insertion of the attachable and detachable component, the mover is formed in a manner such as to be, in conjunction with the knock member, capable of reciprocally moving in the attachment and detachment direction from an initial position most separate from an inside of the device body towards a first tip positon located furthest inside of the device body and being locked at the initial position and a middle position of the first tip position in the attachment and detachment direction, when the mover has moved to the first tip position in a range of the reciprocal movement, a distance between the recording medium attached to the attachable and detachable component and the communication section is in a communicable range, and when the mover has moved to the initial position and the middle position, the distance between the recording medium attached to the attachable and detachable component and the communication section is out of the communicable range.
