Patent number: 9164423Abstract: A developer replenishment container accommodating assembly, in which a developer replenishment container is removably put in a main body of an accommodating apparatus, replenishes a developer while rotating the developer replenishment container and includes a holding portion provided on the main body and configured to hold the developer replenishment container put in the main body of the accommodating apparatus in a replenishment position for replenishing the developer, and an engaging portion configured to engage with the developer replenishment container when it is positioned in the main assembly. In addition, a biasing member is configured to bias the engaging portion in a predetermined direction so that the developer replenishment container rotating while held by the holding portion is pressed against the holding portion by the biased engaging portion.Type: GrantFiled: November 20, 2012Date of Patent: October 20, 2015Assignees: CANON FINETECH INC., CANON KABUSHIKI KAISHAInventors: Kazuhiro Mochizuki, Akira Masuda, Yutaka Ban, Nobuo Nakajima

Publication number: 20140119776Abstract: 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: January 6, 2014Publication date: May 1, 2014Applicant: CANON KABUSHIKI KAISHAInventors: Nobuo Nakajima, Ayatomo Okino, Katsuya Murakami, Toshiaki Nagashima, Yutaka Ban

Patent number: 8126416Abstract: With a power supply provided for a smart antenna, whether the antenna is connected is determined according to whether the power supply is connected. When it is determined that the smart antenna is not connected, power supply to units related only to controlling of the smart antenna is stopped, whereby power saving is realized. Further, user's setting for discriminating kinds of antennas becomes unnecessary and, when a smart antenna is not connected, power supply for the same can be prevented.Type: GrantFiled: August 15, 2008Date of Patent: February 28, 2012Assignees: Funai Electric Co., Ltd., The University of Electro-Communications, DX Antenna Company, LimitedInventors: Nobuo Nakajima, Koichi Gyoda, Eiji Shibuya, Takehiro Onomatsu, Hideto Yoshimura
