Patent number: 9483008Abstract: An image forming apparatus includes an induced voltage detection portion configured to detect an induced voltage Vk in a motor; and an engagement/disengagement completion time detection portion configured to detect an engagement completion time and a disengagement completion time based on the induced voltage Vk detected by the induced voltage detection portion. The engagement completion time is a time at which engagement of a clutch is actually completed. The disengagement completion time is a time at which disengagement of the clutch is actually completed. A control portion determines a command timing based on any one of the engagement completion time and the disengagement completion time detected by the engagement/disengagement completion time detection portion, the command timing being a time at which a command is given to the clutch to perform an engaging operation or a disengaging operation.Type: GrantFiled: December 9, 2015Date of Patent: November 1, 2016Assignee: KONICA MINOLTA, INC.Inventors: Chao Ye, Naoto Sugaya, Munehiro Natsume, Nobuhiro Matsuo, Seiichi Kirikubo

Patent number: 8496097Abstract: A mount damper comprises electrode plates placed on a motor side and a support body side respectively, a control unit for adjusting voltage between the electrode plates, and an electrostrictive polymer member for changing a distance between the electrode plates by the voltage therebetween. The electrostrictive polymer member is also an elastic body sandwiched between the electrode plates and has a hardness changeable with a change in the interelectrode distance. A motor is mounted through this mount damper. The control unit adjusts voltage applied between the electrode plates to a value different from a value causing resonance of the motor and the electrostrictive polymer member, thereby absorbing vibration of the motor during rotation thereof, irrespective of a rotation speed. Thus, the mount damper and the image forming apparatus using it can reliably prevent resonance and absorb vibration constantly even if a device selectively uses plural levels of the rotation speed.Type: GrantFiled: April 7, 2009Date of Patent: July 30, 2013Assignee: Konica Minolta Business Technologies, Inc.Inventors: Teruhiko Fujikura, Munehiro Natsume, Mutsuto Oe, Yuji Kobayashi, Hiroyuki Yoshikawa, Katsuyuki Ikuta

Patent number: 8463162Abstract: The present invention is capable of changing the system speed quickly and highly accurately while using a CVT device with an advantage in its quietness to transmit a driving force to rotative parts. Specifically, in the case of using a sheet of thick paper as a recording sheet, the controller changes, for each of the pulleys, the distance between the pulley segments (S204) while starting up the DC motor as the driving source (S202). After that, the controller performs the feedback control on the rotation of the DC motor, based on a detection signal received from the encoder of the load shaft of the driven pulley, to achieve the target rotation speed of the load shaft (S206: NO, S207).Type: GrantFiled: August 19, 2009Date of Patent: June 11, 2013Assignee: Konica Minolta Business Technologies, Inc.Inventors: Yuji Kobayashi, Hiroyuki Yoshikawa, Teruhiko Fujikura, Munehiro Natsume, Mutsuto Oe, Katsuyuki Ikuta, Yasushi Hieno
