Patent number: 10082666Abstract: 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: GrantFiled: June 1, 2017Date of Patent: September 25, 2018Assignee: Canon Kabushiki KaishaInventors: Tatsuya Hotogi, Atsunobu Mori
