Memory chip, process cartridge and image forming apparatus
An electronic device support member is fitted into and pressingly attached to a cover so that a face on which an electronic device and an antenna are disposed is opposed to the rear face of the cover. A base has a fitting receive portion into which a fitting portion of the cover is to be fitted, on the peripheral edge of the surface opposed to the cover. Two elastic claws are disposed on the peripheral edge of the rear face. A second housing has a recess portion into which a memory chip is to be fitted and secured, in the surface. The recess portion is formed into a circular concave shape, and has two engagement portions for respectively receiving the elastic claws of the memory chip.
1. A memory chip which is to be attached to a unit, said memory chip comprising:
an electronic device having a memory function;
a cover which covers said electronic device; and
a securing section which substantially disables said cover to be detached from said unit from an outside of said unit, wherein said securing section has an elastic claw, and said elastic claw is engaged with said unit to perform securement.
2. A memory chip according to claim 1 , wherein said securing section is easily securable to and substantially undetachable from a surface of a process cartridge which is detachably attached to an image forming apparatus main unit, and which has at least an image carrier.
3. A memory chip according to claim 1 , wherein said electronic device has a communication function.
4. A memory chip according to claim 1 , wherein a base is secured to an inner side of said cover, and said elastic claw is disposed on said base.
5. A memory chip according to claim 1 , wherein said cover is made of a same material as a material of said unit.
6. A memory chip according to claim 1 , wherein said cover is colored in a same color as a color of said unit.
7. A memory chip according to claim 1 , wherein said unit has a recess portion, and said cover is fitted into said recess portion to be secured in a depressed manner.
8. A memory chip according to claim 7 , wherein when said cover is secured to said recess portion in a depressed manner, a surface of said cover is at a same level as a surface of another recess portion of said unit adjacent to said recess portion.
9. A memory chip according to claim 1 , wherein said electronic device is supported by an electronic device support member, and said electronic device support member is secured to an inner side of said cover.
10. A memory chip according to claim 1 , wherein said electronic device support member has an antenna.
11. A memory chip according to claim 1 , wherein said unit is a process cartridge having at least an image carrier.
12. A process cartridge which is detachably attached to an image forming apparatus main unit, and which has at least an image carrier, said process cartridge comprising:
a process cartridge main unit; and
a memory chip attached to said process cartridge main unit,
wherein said memory chip comprises: an electronic device having a memory function; a cover which covers said electronic device; and a securing section which substantially disables said cover from said process cartridge main unit to be detached from an outside of said process cartridge, wherein said securing section has an elastic claw, and said elastic claw is engaged with said process cartridge main unit to perform securement.
13. An image forming apparatus comprising:
an image forming apparatus main unit; and
a process cartridge which is detachably attached to said image forming apparatus main unit, and which has at least an image carrier,
wherein said process cartridge comprises a memory chip including an electronic device having a memory function, a cover which covers said electronic device, and a securing section which substantially disables said cover to be detached from said process cartridge from an outside of said process cartridge, wherein said securing section has an elastic claw, and said elastic claw is engaged with said process cartridge to perform securement.
