Patent number: 9124107Abstract: A charger that charges a battery unit including a secondary battery, includes a receiving unit, a detection unit, a determination unit, and a control unit. The receiving unit receives, from the battery unit, battery state information indicating a state of the battery unit, if the secondary battery is being charged. The detection unit detects charge state information indicating the state of the battery unit, if the secondary battery is being charged. The determination unit determines, using the battery state information and the charge state information, whether the battery unit is in a normal state. The control unit controls charging of the secondary battery in the battery unit depending on whether the battery unit is in the normal state.Type: GrantFiled: September 30, 2011Date of Patent: September 1, 2015Assignee: Canon Kabushiki KaishaInventor: Takamitsu Abe

Patent number: 8030939Abstract: An electronic apparatus which is capable of correctly displaying the remaining usable time even if a discharged current of a battery pack is changed by an unexpected load due to an external apparatus connected. The electronic apparatus has a battery pack with a secondary battery mounted therein. A first remaining usable time of the electronic apparatus is calculated based on a consumed current of the electronic apparatus. A second remaining usable time of the electronic apparatus is calculated based on a discharged current of the secondary battery. The first remaining usable time calculated by the first remaining usable time calculating unit or the second remaining usable time calculated by the second remaining usable time calculating unit, whichever is smaller, is selected, and then a displaying unit displays the selected remaining usable time.Type: GrantFiled: September 1, 2008Date of Patent: October 4, 2011Assignee: Canon Kabushiki KaishaInventor: Takamitsu Abe

Patent number: 7123377Abstract: When a holder of an ID card approaches an image formation instructing device for sending an image forming instruction to an image forming apparatus, an ID code stored in a RF-ID element built in the ID card is read by a RF communication device. When the image formation instructing device transmits an image forming instruction to the image forming apparatus in this condition, an image forming operation is executed and the number of sheets for image formation is counted by counting means. Further, the counted number of sheets for image formation is associated with an ID code having predetermined bearing on the personal ID code read by the RF communication device and thereafter stored and held in a number-of-sheets file. Thus, the number of sheets for image formation is managed without preparing a key counter, a key card, etc. and without special operation.Type: GrantFiled: August 10, 2004Date of Patent: October 17, 2006Assignee: Tohoku Ricoh Co., Ltd.Inventors: Mutsuo Ogawa, Matsuo Yomogida, Takamitsu Abe, Hideaki Matsuda
