In a sheet conveyance apparatus a control unit controls lifting and lowering of a sheet supporting portion by a lifting unit and executes a mixed feeding in one of a plurality of modes including a first mode and a second mode. The mixed feeding is an operation in which a plurality of sheets having different lengths in a width direction orthogonal to a feed direction of a sheet feeding unit are fed by the feeding unit, wherein in the first mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on an instruction to start sheet feeding, and in the second mode, the control unit causes the lifting unit to move the supporting portion from the second position to the first position based on a detection of a sheet by the detection unit.

According to one embodiment, a sheet conveying device includes a roller, a motor, a clutch, and a torque generator. The roller conveys a sheet. The motor is a driving source. The clutch connects or disconnects drive of the motor with respect to the roller. The torque generator applies a torque to the roller.

A peripheral capable of sensing a media count includes a body, a stopper, a supply tray and a sensor assembly. The stopper is installed in the body. The supply tray accommodated within the body includes a base and a frame. The frame elastically and pivotally connected to the base supports media and pushes the media in a direction toward the stopper so that the media contacts the stopper. The sensor assembly installed in the body detects a position state of the frame to obtain a sensing signal corresponding to the number of the media.

A conveyance device includes a tray on an upper surface of the conveyance device and an upper guide below the tray. The tray receives a sheet, and the upper guide defines a conveyance path in which the sheet is conveyed. The upper guide is movable together with the tray to open the conveyance path.

A recording device includes a recording head, a transport roller set, and a controller that controls a driving source that drives a transport driving roller. The controller judges whether a rear end that is an upstream end of a medium in a transport direction crosses a kicking region set in a range present downstream of a nipping position of the transport roller set in a transport direction. When the controller judges that the rear end does not cross the kicking region, the controller adjusts a feeding amount for at least one of a plurality of transport operations to be performed until the rear end reaches the kicking region in such a manner that the rear end of the medium crosses the kicking region.

Provided are a medium conveying apparatus, a control method, and a control program to enable more accurate detennination whether a medium conveyance abnormality has occurred. A medium conveying apparatus includes an ultrasonic transmitter capable of outputting an ultrasonic wave, an ultrasonic receiver opposed to the ultrasonic transmitter, to receive the ultrasonic wave and output an ultrasonic signal corresponding to the received ultrasonic wave, a pressure detection module to detect atmospheric pressure, based on the ultrasonic signal, a sound receiver to receive a sound and generate a sound signal corresponding to the received sound, an abnormality determination module to determine whether a medium conveyance abnormality has occurred, based on the sound signal, and a modification module to modify sensitivity of the sound receiver, correct the sound signal, or modify a criterion for determination of a medium conveyance abnormality by the abnormality determination module, based on the atmospheric pressure.
