A printing apparatus can prevent a print medium from buckling during discharging. In a case in which the print conveyance speed determined by the print mode is higher than or equal to a specified speed, the print medium after printing is conveyed to a discharging tray at the print conveyance speed, and in a case in which the print conveyance speed determined by the print mode is lower than the specified speed, the print medium after printing is conveyed to the discharging tray at the specified speed increased from the print conveyance speed.

Provided is a technique that enables proper sorting of discharged print media by suppressing curling of each of the print media sufficiently. A determining unit determines a curling suppressing operation to be executed such that in a case where sorting operation is executed, the suppressing operation having a higher effect of suppressing curling is executed than in a case where the sorting operation is executed. Then, a print control unit controls a print head to perform printing on print media while executing the suppressing operation determined by the determining unit.

According to examples, a printing apparatus may include an output bin that is laterally translatable between a retracted position and an extended position. The printing apparatus may also include a sensor to detect a height of a stack of media on the output bin while the output bin is in the retracted position and a controller. The controller may determine whether the detected height of the stack of media on the output bin exceeds a certain level and in response to a determination that the detected height of the stack of media exceeds the certain level, laterally translate the output bin from the retracted position to the extended position.

A paper conveyance device includes a paper feed unit, a conveyance rotator, a conveyance guide, a multi-feed detection unit, and a control unit. The control unit causes an ultrasonic sensor to transmit an ultrasonic wave in a detection section. The control unit sets a detection execution section and a detection skip section in the detection section. The control unit does not determine whether multi-feed has occurred in the detection skip section. The control unit sets the detection skip section based on a time point at which vibration is applied to conveyed paper.

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.

A binding device includes a pressing member that has a first tooth, which forms unevenness in a recording material bundle, and a second tooth, which is paired with the first tooth and forms unevenness in the recording material bundle, and presses the recording material bundle with the recording material bundle sandwiched between the first tooth and the second tooth and a control unit that performs control such that pressing is released after a timing when a load on the pressing member decreases from start of pressing of the recording material bundle by the pressing member.
