Patent number: 11123872Abstract: A control apparatus includes a robot having an arm, a driver, an end effector, a first detector, and a second detector, and a control device. The control device acts as a third detector, a calculator, and a controller. The third detector detects a slip direction of the object held by the end effector. The calculator calculates an angle defined by the slip direction detected by the third detector and a direction opposite to gravity. The controller causes the end effector holding the object to pivot by the angle calculated by the calculator, to align the slip direction detected by the third detector with the direction opposite to gravity.Type: GrantFiled: December 12, 2019Date of Patent: September 21, 2021Assignee: KYOCERA Document Solutions Inc.Inventor: Haruki Shoji

Patent number: 9880509Abstract: An image forming apparatus includes an image carrier, a motor, a cleaning portion, a measurement processing portion, and a cleaning control portion. The image carrier is configured to carry an electrostatic latent image. The motor is configured to rotate the image carrier. The cleaning portion is configured to clean the image carrier. The measurement processing portion is configured to measure a transition time that is a time required for the motor to transition from a stationary state to a driving state in which the motor rotates at a predetermined speed. The cleaning control portion is configured to control a cleaning time of the cleaning portion or whether or not to cause the cleaning portion to clean the image carrier.Type: GrantFiled: May 26, 2016Date of Patent: January 30, 2018Assignee: KYOCERA Document Solutions Inc.Inventors: Haruki Shoji, Okito Ogasahara, Naohiro Anan

Patent number: 9772491Abstract: An image forming apparatus includes a rotating polygon mirror, a motor, a bearing portion, a measurement processing portion, and a determination processing portion. The rotating polygon mirror causes a light beam emitted from the light source to be scanned. The motor rotates the rotating polygon mirror. The bearing portion rotatably supports a rotation shaft of the motor via a lubricant. The measurement processing portion measures a transition time that is a time required for the motor to transition from a stationary state to a driving state in which the motor rotates at a predetermined speed. The determination processing portion determines whether or not a maintenance is required, based on the transition time measured by the measurement processing portion.Type: GrantFiled: May 26, 2016Date of Patent: September 26, 2017Assignee: KYOCERA Document Solutions Inc.Inventors: Haruki Shoji, Okito Ogasahara, Naohiro Anan
