Patent number: 7085508Abstract: Provided is a timing control unit that controls timing for performing a desired operation of a belt-like member at least at two operating positions including a first and second operating positions. The distance between the first and second operating positions is set to a multiple of a perimeter of the drive roll. The timing control unit includes a clock generation part for generating a clock signal having a constant period in accordance with rotation of the drive roll, and a count part for counting the clock signal generated by the clock generation part. The count part counts the clock signal generated by the clock generation part for the number corresponding to the multiple of the perimeter of the drive roll, thereby operation timing at the second operating position is synchronized with operation timing at the first operating position.Type: GrantFiled: November 3, 2003Date of Patent: August 1, 2006Assignee: Fuji Xerox Co., Ltd.Inventor: Masatomo Igarashi
