Publication number: 20100278565Abstract: If a user is not familiar with the operation for the developer supply container, the rotating operation for the developer supply container may be insufficient, so that developer supply container does not reach a predetermined operating position, with the result of abnormal developer supply. by increasing a rotation load of a second gear 6 which is in an operable connection with a drive gear member 12 of the developer receiving apparatus 10 by a function of a locking member 7, the developer supply container 1 mounted to the developer receiving apparatus 10 is rotated toward the supply position. After the developer supply container 1 rotates to the supply position, the locking by the locking member 7 is released, by which the rotation load applied to the second gear 6 is reduced, so that drive transmission, thereafter, to the feeding member 4 for developer supply is smooth.Type: ApplicationFiled: July 15, 2010Publication date: November 4, 2010Applicant: CANON KABUSHIKI KAISHAInventors: Nobuo Nakajima, Ayatomo Okino, Katsuya Murakami, Toshiaki Nagashima, Yutaka Ban

Patent number: 7822372Abstract: In a structure in which a gear train 5, 6 of a developer supply container 1 is locked by a locking member 7, and by the gear train 5, 6 receiving a drive from a gear 12 of the developer receiving apparatus, the setting rotation of the developer supply container 1 is automatically carried out, the setting rotation of the developer supply container 1 is not possible if a releasing projection 5a is at a position interfering a locking member 7. In view of this, the gear 5 is rotated to effect the locking member 7 to lock by abutment of an engaging portion 5d of the gear 5 to an engaging portion 13a of the developer receiving apparatus 10 with inserting operation of developer supply container 1. Therefore, upon completion of the insertion of the developer supply container 1, the gear train 5, 6 is locked by the locking member 7, and therefore, the setting rotation of the developer supply container 1 can be carried out properly.Type: GrantFiled: May 23, 2007Date of Patent: October 26, 2010Assignee: Canon Kabushiki KaishaInventors: Toshiaki Nagashima, Katsuya Murakami, Ayatomo Okino
