Media transport device and liquid dispensing device

Abstract

The configuration allows the transport unit to be detached from the main body of the device, thereby improving the work efficiency of each operation. [Solution] A media transport device 30 comprising a device body 12, a media storage cassette 13 configured to be retractable from the device body 12, a transport unit 20 having part of a transport path T for transporting media M stored in the media storage cassette 13, a support tray 21 provided integrally with the transport unit 20 and capable of supporting media M, and an openable and closable cover 14 provided to cover an opening 18, wherein the cover 14 can take a first position that covers the opening 18, a second position that allows the supply of media M from the support tray 21, and a third position that allows the transport unit 20 to be attached to and detached from the device body 12.

Claims

1. The main body of the device, A media storage cassette configured to be retractable in the pulling direction relative to the main body of the device, A transport unit comprising a transport path that transports the media contained in the media storage cassette, A support tray, which is provided integrally with the transport unit and capable of supporting the medium, The device body is provided with a cover that can cover an opening located downstream of the transport unit in the pulling direction, and the cover is openable and closable with the direction intersecting the pulling direction being the direction in which the pivot axis extends. Equipped with, A media conveying device characterized in that the cover can take a first position in which it covers the opening; a second position in which the rotating tip opposite to the pivot axis is located further downstream in the pulling direction than in the first position, enabling the feeding of media from the support tray; and a third position in which the rotating tip is located further downstream in the pulling direction than in the second position, allowing the conveying unit to be attached to and detached from the main body of the device.

2. In the media transport device according to claim 1, The medium transport device is characterized in that the transport unit is a reversal path unit that constitutes at least a part of the reversal path that reverses the medium within the transport path.

3. In the media transport device according to claim 1 or 2, The conveying unit is characterized by comprising a placement section for placing the medium supported on the support tray, and a hopper section capable of switching the inclination angle of the placement section as viewed from the direction in which the pivot axis extends.

4. In the media transport device according to claim 1 or 2, The media conveying device is characterized in that the conveying unit comprises a separation roller for separating the media supported on the support tray.

5. In the media transport device according to claim 1 or 2, The conveying unit is characterized by comprising a supply roller that supplies the medium supported on the support tray.

6. In the media transport device according to claim 1 or 2, The cover has a position-maintaining portion having a projection provided on one of the cover and the opening, and a hole provided on the other of the cover and the opening that engages with the projection, The media transport device is characterized in that the posture maintenance unit has three of at least one of the protrusions and holes, thereby enabling the cover to be maintained in at least three postures: the first posture, the second posture, and the third posture.

7. In the media transport device according to claim 1 or 2, A media transport device characterized by having a biasing part that biases the cover in a direction opposite to the direction of rotation caused by gravity.

8. In the media transport device according to claim 1 or 2, The main body of the apparatus is provided with a support portion that supports the transport unit on a support surface, The media transport device is characterized in that the cover maintains its position without any step difference with the support surface in the third position.

9. In the media transport device according to claim 1 or 2, An operating unit used when attaching or detaching the transport unit from the main body of the device, The support tray is provided with a through hole that allows access to the operating section, A cross-direction cover portion is provided on the cover and covers a part of the main body of the device in a cross-direction that intersects with the pulling direction and the direction in which the pivot axis extends when the cover is in the first position, Equipped with, The media transport device is characterized in that the intersecting direction cover portion is provided in a position that does not overlap with the through hole when viewed from a direction along the draw-out direction when the cover is in the third position.

10. A liquid dispensing section that dispenses liquid, A media transport device according to claim 1, A liquid dispensing device characterized by comprising the following features.
