Publication number: 20170363862Abstract: A CPU is provided which controls a first light emission state in which a light source is controlled to emit a light beam to scan a full-scanning region and a second light emission state in which the light source is controlled to emit a light beam to scan a non-image region in a period from start of activation of a scanning motor to when the number of rotations of the scanning motor reaches a target number of rotations. The CPU acquires BD cycle values of BD signals generated by a main-scanning synchronization sensor, determines a second timing for changing from the first light emission state to the second light emission state on the basis of the two serial BD cycle values, and changes the semiconductor laser from the first light emission state to the second light emission state according to the second timing.Type: ApplicationFiled: June 1, 2017Publication date: December 21, 2017Inventors: Tatsuya Hotogi, Atsunobu Mori

Patent number: 8244150Abstract: A fixing apparatus allows harmonic noise and flicker noise caused by alternating current to be reduced. To accomplish this, the fixing apparatus has a power supply unit that supplies AC power from a commercial power supply to a heater, a temperature detection element that detects the temperature of the heater, a setting unit that sets a duty ratio for providing power to the heater such that the temperature detected by the temperature detection element maintains a target temperature, and a control unit that controls the power supply unit such that an average power duty ratio of a single cycle equals the power duty ratio based on the detected temperature, where a single cycle is three or more full waves of the commercial power supply, there being three or more power duty ratios per one half wave of the commercial power supply in a single cycle.Type: GrantFiled: June 2, 2010Date of Patent: August 14, 2012Assignee: Canon Kabushiki KaishaInventors: Hiromitsu Kumada, Teruhiko Namiki, Atsunobu Mori
