Provided is a printing apparatus comprising: a discharging unit configured to convey and discharge print media; a tray configured to receive print media discharged in a first direction from the discharging unit; and a drive unit configured to move the tray in a second direction perpendicular to the first direction. In discharging print media, the tray is moved in the second direction to thereby receive the discharged print media at a plurality of different positions on the tray. The tray is movable to a take-out position being a position closer in the second direction to a take-out side where print media are taken out than any of the positions at which the tray receives the print media discharged from the discharging unit.

A sheet discharge apparatus includes a sheet discharging portion, a sheet supporting portion, a pivot member configured to pivot by being pressed by the sheet discharged from the sheet discharging portion, a detecting unit configured to detect a position of the pivot member, and a control unit configured to change a sheet interval. The control unit executes a first discharge operation in which at least one sheet is discharged, a second discharge operation in which sheets are discharged at a first sheet interval, and a third discharge operation in which at least one sheet is discharged at a second sheet interval that is longer than the first sheet interval, a number of sheets discharged in the second discharge operation being acquired based on a detection result of the detecting unit detected during the first discharge operation.

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.

A medium conveying apparatus includes a pick roller feeding a medium, a separation roller placed on a downstream side of the pick roller in a conveying direction of a medium, an arrival detection sensor placed on a downstream side of the separation roller in the conveying direction and detecting arrival of a medium, a lift sensor detecting a lift of a medium between an upstream side of a roller nip of the pick roller and a downstream side of a roller nip of the separation roller, and a processor. The processor determines that a medium is a bound medium when a lift of a medium is detected by the lift sensor in a first predetermined period after detection of a front edge of a medium in a conveying direction by the arrival detection sensor, and executes abnormality processing when a medium is determined to be a bound medium.

A sheet detection device includes, as detection pieces, a first detection piece integrally provided on a rotary shaft and a second detection piece attached to the first detection piece via a biasing member. The second detection piece is capable of rotation in conjunction with the first detection piece under a biasing force of the biasing member. When the second detection piece is brought into contact with a ceiling at an upper part of the rotary shaft, the second detection piece stops further rotation while the first detection piece is capable of rotation together with the rotary shaft against the biasing force.

Technology enabling correctly detecting that paper has been delivered from a paper roll to the trailing end A printer has an inkjet head; a roll paper support; a delivery motor configured to rotate the roll paper supported by the roll paper support; a guide member configured to guide roll paper conveyed from the paper roll; and a detection switch disposed to a position where it detects the conveyed roll paper when the delivery point on the circumference of the paper roll moves to the part of the circumference of the roll on the same side of an imaginary line as the guide member; the delivery point being from which the conveyed roil paper separates from the roil when the paper roll turns; and the imaginary line being tangent to the guide member and passing through the center of the roll.

A meandering control device includes: a detector configured to detect a position of an edge of a web being conveyed in a width direction of the web; a corrector configured to correct a position of the web being conveyed in the width direction; and a controller including a digital filter configured to perform filtering on a position signal indicating the position of the edge detected by the detector to attenuate a noise component. The controller is configured to drive the corrector to correct the position of the web in the width direction based on the position signal after the filtering.

Provided is a printing apparatus that prevents a print medium from buckling during discharging, a method of controlling a printing apparatus, and a storage medium. In the case where the print conveyance speed determined by the print mode is higher than or equal to the specified speed, the print medium after printing is conveyed to the discharging tray at the print conveyance speed, and in the case where the print conveyance speed determined by the print mode 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 printer that can appropriately handle a paper (media) wound into a roll with one end of the paper affixed to a core, when the trailing end of the paper is detected, the trailing end of the paper being attached to the winding core in multiple ways. The printer has: a roll paper support that supports the core of a roll of paper; a roll driver that turns the core and delivers the paper; a conveyance device that conveys the delivered paper; a tension detection switch that outputs a first detection value when tension produced on the paper delivered from the roll is greater than or equal to a threshold; and a controller that drives the roll driver in the direction delivering the paper when the output of the tension detection switch changes to the first detection value in response to rotation of the core.

A sensor unit includes an edge detection sensor, a sensor carriage, a unit housing, and a carriage moving mechanism. The edge detection sensor is arranged in a conveying portion for conveying a sheet and senses edge positions at both sides in a sheet width direction perpendicular to a sheet conveying direction. The sensor carriage has a carriage main body in which the edge detection sensor is incorporated, and is reciprocatably supported on the unit housing in the sheet width direction. The carriage moving mechanism makes the sensor carriage reciprocate in the sheet width direction. The sensor carriage is selectively positioned at a first position where it makes contact with a first side face at one end side of the unit housing in the sheet width direction or a second position where it makes contact with a second side face at the other end side in the sheet width direction.
