Abstract:
A gear engagement mechanism of a life device includes a lifting member interlocking with a lifting tray to linearly move in a vertical direction, and a gear train having a pinion engaged with the rack to transmit a rotary motion to the rack and transmitting the rotation torque of a lift motor M to the pinion. When the lifting member has over-run an upper limit stop position and a lower limit stop position, engagement of the pinion and the rack is released.
Abstract:
A sheet conveying device that conveys a sheet includes a sheet conveying path, a conveying mechanism, and a guiding plate. The sheet conveying path is set to include a nonlinear portion. The conveying mechanism is arranged in the sheet conveying path to convey a sheet. The guiding plate is arranged in the nonlinear portion of the sheet conveying path and has a guiding plane along which the sheet is guided. The guiding plate includes a thinned portion in an area of the guiding plane against which a leading end of the sheet being conveyed along the sheet conveying path collides so that the thinned portion suppresses high frequency components of an impulsive sound produced by the collision.
Abstract:
According to the present disclosure, a recording medium feeding device includes a pickup roller, a feed roller, a retard roller, a holding member, a pressing mechanism, a pressing force changing mechanism, and a driving force transmitting mechanism. The holding member is configured to rotatably support the feed roller and the pickup roller. The pressing mechanism is configured to press the pickup roller against a recording medium. The pressing force changing mechanism is configured to change the pressing force of the pickup roller. The driving force transmitting mechanism is configured to transmit a rotation-driving force to the feed roller. The pressing force changing mechanism obtains a driving force from the driving force transmitting mechanism, and increases the pressing force according to rotation time of the pickup roller.
