PROBLEM TO BE SOLVED: To avoid incorrect detection of lock of a motor subjected to stop control while holding a position of the motor, and stop the motor with the position of the motor being held.SOLUTION: A motor control device includes: a motor lock state determination unit 23 that determines as to whether a motor 5 is in a lock state from rotation information of the motor 5; a position hold state determination unit 24 that determines as to whether the motor 5 is in a position hold state; a lock detection disablement determination unit 25 that disables the determination of the motor 5 in the lock state when the motor 5 is in the position hold state and predetermined conditions defined in advance are satisfied; a position error correction unit 26 that corrects an error relative to a target stop position of the motor 5 to be within a predetermined range when the rotation of the motor 5 is stopped in a lock disabled period; and a motor control unit 27 that controls to change a direction of rotation of the motor 5 in a time period shorter than a time period in which the motor 5 is determined to be in the lock state, when the motor 5 is in the position hold state and after the correction of the error.
摘要:
A medium ejection apparatus is provided which may be part of an image forming apparatus. The medium ejection apparatus may include an ejection roller configured to eject a recording medium and a pinch roller disposed opposite to the ejection roller. The pinch roller is configured to move toward and away from the ejection roller and to press a recording medium toward the ejection roller. Also, the medium ejection apparatus may include an elastic member configured to press the pinch roller toward the ejection roller and a lever disposed downstream of the pinch roller in a recording medium transport direction. The lever is configured to be moved between a first position and a second position. When the lever is in the second position, the lever contacts the pinch roller, which causes a force to be applied against the elastic member, and the pinch roller is spaced away from the ejection roller.

PROBLEM TO BE SOLVED: To simplify a system for monitoring an overload in a paper stack raising mechanism of a sheet processing machine. SOLUTION: It is proposed to deduce a limit height H of a paper stack for a stack of sheet paper 5 to be processed from a standard size or a density of printing matter to be processed. Therefore, the sheet paper can be counted for that and a stack of sheet paper can be measured with a sensor. COPYRIGHT: (C)2006,JPO&NCIPI
