Abstract: Disclosed are a printing device, a system and a method for printing medium feed. A device may comprise a support member and multiple rollers. The support member may support a print medium. The multiple rollers may each advance the print medium from the support member in an advance direction. The multiple rollers are arranged in a distributed manner along a width direction. The multiple rollers are operable in a disengage state detached from the print medium and the support member and in an engage state of pressing against the support member such to rest on the print medium or, if the print medium does not extend therebetween, to rest on the support member. The multiple rollers in the engage state are individually movable toward the support member.

Abstract: An image forming apparatus includes a paper feeding cassette, a first conveying unit, a lift mechanism, a motor, a second conveying unit, and a control unit. The controller drives the motor and, if a value indicating a movement amount of the tray moving from when the lift mechanism starts the lifting of the tray until when a position of the top part reaches a first position is a first value, matches a position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a second position and, if the value indicating the movement amount is a second value larger than the first value, matches the position of the first conveying unit, which comes into contact with the top part to thereby rise together with the tray, with a third position lower than the second position.

Abstract: An image processing apparatus includes: a support surface configured to support a sheet, a sheet feeding roller configured to feed the sheet in a conveying direction, a separation member for separating the sheet one by one and positioned downstream of the sheet feeding roller in the conveying direction, and a regulating member displaceable between a first position where the regulating member abuts against a distal end of the sheet supported by the support surface to regulate passage of the sheet in the conveying direction between the sheet feeding roller and the separation member and a second position that is farther from a conveyance path than the first position and that allows passage of the sheet in the conveying direction. The regulating member has a wall surface that abuts against the distal end of the sheet and includes at least one protrusion on the wall surface.

Abstract: A sheet conveyance apparatus includes a base unit, a sheet stacking portion, a feeding portion, an open/close member, a conveyance guide member, a protruding portion, and a fitted portion. The feeding portion feeds a sheet stacking portion stacked sheet. The open/close member includes an upper guide facing an upper surface of the fed sheet. The conveyance guide member includes a lower guide facing a lower surface of the fed sheet and forms a sheet conveyance path with the upper guide. The protruding portion is provided on one of the open/close member and the conveyance guide member. The fitted portion is on the other of the open/close member and the conveyance guide member and is fitted with the protruding portion. In a state where the open/close member is closed, a position of the conveyance guide member in a width direction is determined by the protruding portion fitting into the fitted portion.

Abstract: A sheet conveying device includes a pickup roller, a separator, a conveyor, and circuitry. The pickup roller contacts an uppermost sheet of sheets stacked on a sheet stacker and feed the uppermost sheet. The separator moves the pickup roller between a contact position at which the pickup roller is in contact with the uppermost sheet and a separation position at which the pickup roller is separated from the uppermost sheet. The conveyor conveys the uppermost sheet fed by the pickup roller. The circuitry is to control the conveyor to temporarily stop conveyance of the uppermost sheet, and control the separator to move the pickup roller from the contact position to the separation position in response to the temporarily stop of the conveyor.

Abstract: A sheet conveying apparatus includes a transmitting mechanism-, a movable member, and a control portion to input a signal having first and second levels. The transmitting mechanism transmits driving force and includes a spring clutch and an electromagnetic clutch. The driving force pivotally moves the movable member. The spring clutch idles by a slackness of a spring when the rotation in a second direction is inputted to the transmitting mechanism and the movable member is regulated from pivoting at a predetermined position. The control portion inputs the signal to the transmitting mechanism such that the state electromagnetic clutch state changes the engagement state to the disengagement state through an intermediary state gradually varying a length of time where the signal of the first level is inputted into the electromagnetic clutch after the movable member reaches the predetermined position by inputting the rotation in the second direction to the transmitting mechanism.
