A printer includes a transport roller (driving roller, driven roller, counter roller) that is disposed in a casing, and configured to transport a sheet to be fed from roll paper, an image forming portion (thermal head) that is disposed in a cover (upper cover) of the casing, and configured to form an image on the sheet; and a platen roller that is disposed in the casing to face the image forming portion (thermal head). The image forming portion (thermal head) is movable in transport directions (feeding direction, drawing back direction) of the sheet, and the platen roller is movable in directions substantially vertical to the transport directions (feeding direction, drawing back direction).

A printing device includes a medium holding portion a medium holding portion on which a medium is placed, a discharge unit, a holding portion, a first displacement mechanism, a second displacement mechanism, and a contacting portion of the medium holding portion. The discharge unit is configured to discharge an object to the medium placed on the medium holding portion. The holding portion is configured to hold the discharge unit. The first displacement mechanism is configured to displace a relative position of the medium and the discharge unit along a placement surface of the medium. The second displacement mechanism is configured to displace the medium holding portion along a height direction. The contacting portion configured to come in contact with a contacted portion located at a surface of the medium holding portion, the medium placed on the surface.

Provided is a printing apparatus including a support portion configured to support a medium, a printing unit configured to carry out printing onto the medium supported by the support portion, a support portion moving unit configured to move at least a part of the support portion in a facing direction in which the support portion and the printing unit face each other to change a support position of the medium in the facing direction, a detected unit having position information in the facing direction, the detected unit being configured to move in the facing direction together with the support portion, a detector configured to detect the position information, and a control unit configured to detect a position of the support portion in the facing direction, based on the position information detected by the detector.

A liquid ejecting device includes a support portion configured to support a medium, an ejecting unit configured to eject liquid, a detector including sensors, and a control unit configured to determine, based on a detection result from the detector, a first space being a space between the ejecting unit and the medium. The sensors include a first sensor, a second sensor provided downstream of the first sensor in an ejection direction, and a third sensor provided at a position between the first sensor and the second sensor in the ejection direction. The control unit determines that the first space is in an error state when the first sensor detects the medium, and determines the first space based on a detection result of the medium when the first sensor does not detect the medium but at least one of the second sensor and the third sensor detects the medium.

While a cover moves to a closed position, a second engagement portion contacts a first engagement portion to displace the first engagement portion, and thus a guide portion moves to a guide position. While the cover moves from the closed position to a first open position, the second engagement portion and the first engagement portion are separated, and the guide portion moves from the guide position to an open position.
