Abstract
A toner cartridge, a developing device, and an image forming apparatus, in which a memory is provided in the cartridge to be accessible by an image forming apparatus are disclosed. The image forming apparatus includes a developing device detachably attached to the body the image forming apparatus, and a toner cartridge detachably disposed in the developing cartridge, which includes a memory accessible from a surface of the toner cartridge exposed outside the developing cartridge when the toner cartridge is installed in the developing cartridge.
Claims48
A developing apparatus, comprising
- a developing cartridge having formed therein a recess having a depth extending into the developing cartridge;
- a toner cartridge detachably mounted in the recess of the developing cartridge, the toner cartridge having an exposed surface that is at least partially exposed outside the developing cartridge when the toner cartridge is mounted in the recess;
- and
- a memory accessible from the exposed surface.
An image forming apparatus, comprising:
- a main body;
- a developing cartridge detachably supported in the main body;
- a toner cartridge detachably supported in the developing cartridge, the toner cartridge being configured to supply toner to the developing cartridge;
- and
- a memory accessible from an exposed surface of the toner cartridge, the exposed surface being at least partially exposed outside the developing cartridge when the toner cartridge is supported in the developing cartridge.
A toner cartridge, comprising
- a toner cartridge body defining an inner volume in which to accommodate toner;
- a toner transferring member rotatably mounted in the toner cartridge body, the toner transferring member being configured to receive, at a first end of the toner cartridge body, a driving force from an external driving force source, to rotate to thereby cause a movement of toner in the toner cartridge body;
- and
- a memory accessible through one or more access terminals arranged on a surface of a second end opposite the first end of the toner cartridge body.
An apparatus, comprising:
- a memory accessing unit having a main body, the main body including one or more contact terminals;
- a first detachable unit detachably supported in the main body, the first detachable unit being receivable into the main body in a first direction;
- a second detachable unit detachably supported in the first detachable unit, the second detachable unit being receivable into the first detachable unit in a second direction perpendicular to the first direction, the second detachable unit including an exposed surface that is at least partially exposed outside the first detachable unit when the first detachable unit is received in the first detachable unit;
- a memory accessible through one or more access terminals arranged on the exposed surface, the one or more access terminals coming into contact with the one or more contact terminals of the main body so as to establish signal communication between the memory and the memory accessing unit.
A memory device including a second unit received into a first unit in a first direction, a memory being disposed on a third unit received into the second unit in a second direction so as to allow a transfer of a signal between the first unit and the third unit, the memory device comprising:
- four terminals formed on a portion of the memory device exposed externally while the third unit is mounted in the second unit at a predetermined length in the first direction.
