Abstract

A cartridge used for forming an image on a recording material includes a memory for storing information, wherein the memory has an outer configuration having a length in a first direction and a length in a second direction longer than the length in the first direction in a plane crossing a thickness direction thereof; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of the memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of the memory inserted in the supporting portion. A prevention width of the slit with respect to a direction crossing the thickness direction of the memory is longer than the length of the memory in the first direction and is shorter than the length of the memory in the second direction as seen in an inserting direction of the memory.

First claim

What is claimed is:

1 . A cartridge used for forming an image on a recording material, comprising:
a memory for storing information, wherein said memory has an outer configuration having a length in a first direction and a length in a second direction longer than the length in the first direction in a plane crossing a thickness direction thereof; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of said memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of said memory inserted in said supporting portion, wherein a prevention width of the slit with respect to a direction crossing the thickness direction of said memory is longer than the length of said memory in the first direction and is shorter than the length of said memory in the second direction as seen in an inserting direction of said memory.

2 . A cartridge used for forming an image on a recording material, comprising:
a memory, provided with a plurality of electrical contacts, for storing information; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of said memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of said memory inserted in said supporting portion, wherein the plurality of electrical contacts are provided and arranged along a longitudinal direction of said cartridge.

3 . A cartridge according to claim 1 , wherein the inserting direction of said memory and the second direction are the same direction.

4 . A cartridge according to claim 1 , wherein said memory is provided with a pair of electrical contacts arranged in the second direction.

5 . A cartridge according to claim 1 , wherein the slit is open toward the second cartridge constituent member.

6 . A cartridge according to claim 1 , wherein the first cartridge constituent member includes a portion-to-be-urged for receiving an urging force from an apparatus main assembly in the thickness direction of said memory and a portion-to-be-positioned where said memory is positioned relative to the apparatus main assembly by the urging force.

7 . A cartridge according to claim 6 , further comprising a color display member for displaying color information of a developer,
wherein in the plane crossing the thickness direction, with respect to the inserting direction of said memory, said memory is disposed toward an end portion side than said color display member.

8 . A cartridge according to claim 6 , wherein the urging force from the apparatus main assembly generates by electrical connection of a main assembly electrical contact of the apparatus main assembly with said memory.

9 . A cartridge according to claim 1 , further comprising a developer carrying member for supplying the developer to an image bearing member on which a latent image is to be formed, and a developer accommodating portion in which the developer is accommodated.

10 . A cartridge according to claim 1 , further comprising a rotatable image bearing member on which a latent image is to be formed.

11 . A cartridge according to claim 1 , wherein said preventing portion has flexibility.

12 . A cartridge according to claim 1 , wherein said first cartridge constituent member is a side wall member, and said second cartridge constituent member is a container for accommodating a developer.

13 . An image forming apparatus comprising:
a cartridge according to claim 1 ; mounting means for detachably mounting said cartridge; feeding means for feeding a recording material; and a main assembly electrical contact for being electrically connected with the memory.

14 . A manufacturing method of a cartridge used for forming an image on a recording material including,
a memory for storing information, wherein said memory has an outer configuration having a length in a first direction and a length in a second direction longer than the length in the first direction in a plane crossing a thickness direction thereof; a supporting portion provided on a first cartridge constituent member and provided with a slit for permitting insertion of said memory; and a preventing portion, provided on a second cartridge constituent member, for preventing movement of said memory inserted in said supporting portion, wherein a prevention width of the slit with respect to a direction crossing the thickness direction of said memory is longer than the length of said memory in the first direction and is shorter than the length of said memory in the second direction as seen in an inserting direction of said memory, said manufacturing method comprising, inserting the memory into the slit; and assembling the first and second cartridge constituent member with each other.

15 . A manufacturing method according to claim 14 , wherein the preventing portion has flexibility.
