According to aspects of the present disclosures, there is provided a tray swinging mechanism including a document tray. A movable plate of the document tray is configured to be swingable about a tray shaft and extends leftward. A lifter is configured to be swingable about a lifter shaft extending in the front-rear direction at a position different from the tray shaft. On a lower surface of the movable plate, a cam surface configured to contact a tip of the lifter is formed. The cam surface includes a parallel part parallel to an upper surface of the movable plate and a curved part spaced from the upper surface farther toward a right side. According to a shape of the cam surface, each time the lifter is rotated by a particular angle, the tip of the movable plate moves by a particular amount.

There is provided a printing apparatus including: a recorder; first and second conveying rollers; a first member which includes the first conveying roller and in which the first conveying roller is supported shakably; and a second member which includes the second conveying roller. The first member includes: a roller support having: an extending part which extends in an extending direction of a rotation shaft of the first conveying roller, and first and second supports which rotatably supports first and second ends of the rotation shaft of the first conveying roller, respectively; and at least one pressing part configured to press a central area of the extending part in a pressing direction extending from the first conveying roller to the second extending roller, in a state that the first and second conveying rollers are brought into contact with each other.

A sheet conveyance apparatus includes a guide member rotatably provided above a supporting portion and including a first guide portion and a second guide portion. The sheet conveyance apparatus further includes a controller configured to control a driving portion to start a rotation of the guide member in a state in which a trailing end of a preceding sheet is at a position above the first guide portion such that the trailing end of the preceding sheet is moved from the position above the first guide portion to a position between the second guide portion and the supporting portion by the rotation of the guide member and that a succeeding sheet conveyed by the conveyance member subsequently to the preceding sheet passes the position above the first guide portion after the rotation of the guide member.

The disclosure describes a method for aligning a card on a printer belt. A printer includes the belt, a print unit having a head, and a card feeder having an alignment bracket. The card feeder deposits a card onto the belt along a processing axis in a first orientation. The belt moves the card away from the card feeder in a first direction. The card feeder is positioned in a second orientation where the alignment bracket aligns with the belt. The alignment bracket has a rear wall and a guide extending therefrom that align the card within the alignment bracket. The belt is overdriven in a second direction and the card moves into the alignment bracket for alignment. The belt then moves in the first direction and the card clears the alignment bracket. The card feeder is then positioned in a third orientation to allow printing with the head.

An image reading device includes: a controller which performs a first drive operation for rotating the discharge roller, and a second drive operation for moving the discharge guide between the third position and the fourth position. The controller stops the first drive operation when performing the second drive operation, and stops the second drive operation when performing the first drive operation.

An image reading device includes: a discharge guide including a discharge opening for discharging the sheet conveyed by the conveyance guide to the discharge tray, the discharge guide being configured to move from a third position to a fourth position according to the decrease in the number of the sheet to be supported by the supply tray, the fourth position being higher than the third position; a discharge roller configured to discharge the sheet through the discharge opening; and a first drive source which generates a first drive force for moving the discharge guide between the third position and the fourth position, wherein the first drive force is also used for rotating the discharge roller.

An image reading device includes: a supply tray including a movable plate which moves from a first position to a second position according to a decrease in the number of sheet to be supported by a supply tray; a discharge guide including a discharge opening for discharging the sheet conveyed by a conveyance guide to a discharge tray, and moves from a third position to a fourth position according to the decrease in the number of the sheets to be supported by the supply tray; a first drive source and a first drive train that transmits a drive force from the first drive source to a discharge roller. The discharge roller discharges a sheet through a discharge opening by receiving the drive force from the first drive source.

An image reading apparatus, includes: a supply tray; a discharge tray; a conveyance guide; a reading sensor; a discharge unit, which includes a discharge opening to discharge the sheet conveyed by the conveyance guide to the discharge tray and is configured to move from a third position to a fourth as the document supported by the paper feed tray is decreased, the fourth position being higher than the third position; a first drive source, which generates a drive force; a first rotation body, which moves the movable plate by transmitting the drive force from the first drive source to the movable plate; and a second rotation body, which moves the discharge unit by transmitting the drive force from the first drive source to the discharge unit, wherein a diameter of the first rotation body and a diameter of the second rotation body are different from each other.

An image reading apparatus includes: a supply tray, which supports sheets to be supplied and includes a movable plate configured to move from a first position to a second position as the sheet supported by the supply tray is decreased, the second position being higher than the first position; a discharge tray; a conveyance guide; a reading sensor; a discharge unit, which includes a discharge opening to discharge the sheet conveyed by the conveyance guide to the discharge tray and is configured to move from a third position to a fourth position as the sheet supported by the paper feed tray is decreased, the fourth position being higher than the third position; and a first drive source, which generates a drive force, wherein the discharge unit is configured to move by receiving the drive force and to transmit the drive force to the movable plate.
