Patent number: 10365599Abstract: An image forming apparatus operable at a plurality of image forming speeds includes a pattern detection unit configured to detect a registration correction pattern at a first image forming speed, a writing start timing determination unit configured to determine writing start timing at which an electrostatic latent image is started to be written on a photosensitive member by a light beam emitted from a light source, and a storage unit configured to store in advance a correction amount for correcting the writing start timing. When the image forming apparatus operates at the first image forming speed set in advance, an image is formed at the writing start timing determined by the writing start timing determination unit. When the image forming apparatus operates at a second image forming speed, an image is formed at a writing start timing corrected based on the correction amount and a speed ratio.Type: GrantFiled: May 2, 2017Date of Patent: July 30, 2019Assignee: Canon Kabushiki KaishaInventor: Satoru Takezawa

Patent number: 10365602Abstract: Provided is a hole punching apparatus that is capable of improving the accuracy of stopping at a target reference position. The hole punching apparatus executes a hole-punching process and a braking process, and includes a rotation-detecting unit and a brake-control unit. The hole-punching process punches punch holes by rotating a hole-punching shaft from a reference position. The brake-control unit intermittently turns ON and OFF a short-circuit brake in the braking process. The brake-control unit sets a braking period for turning ON the brake according to the rotation position and rotation speed of the hole-punching shaft that is measured based on the rotation-position signal so that the braking period tends to become longer as the rotation position becomes closer to the reference position, and tends to become longer as the rotation speed becomes faster.Type: GrantFiled: December 20, 2017Date of Patent: July 30, 2019Assignee: KYOCERA Document Solutions Inc.Inventor: Seiji Kaminaga
