Abstract

A printer performing a printing operation on a roll sheet includes a roll sheet holder in which the roll sheet is stored, a roll sheet input port through which the roll sheet is input to the roll sheet holder, an opening/closing cover unit that opens and closes the roll sheet input port, and a link member that links the opening/closing cover unit with the roller sheet holder. The opening/closing cover unit is movable among an open position, a closed position, and a support position between the open position and the closed position.

First claim

What is claimed is:

1 . A printer performing a printing operation on a roll sheet comprising:
a roll sheet holder in which the roll sheet is stored; a roll sheet input port through which the roll sheet is input to the roll sheet holder; an opening/closing cover unit that opens and closes the roll sheet input port; and a link member that links the opening/closing cover unit with the roller sheet holder, wherein the opening/closing cover unit is movable among an open position, a closed position, and a support position between the open position and the closed position.

2 . The printer according to claim 1 , wherein the link member moves the roll sheet holder to a takeout position at which the roll sheet is able to be taken out through the roll sheet input port when the opening/closing cover unit is moved to the open position, and
the link member moves the roll sheet holder to a storage position which is deeper in the roll sheet input port than the takeout position when the opening/closing cover unit is moved to the closed position.

3 . The printer according to claim 2 further comprising:
a frame in which a guide groove is formed; and
a movable shaft that moves along the guide groove,
wherein the movable shaft is disposed in a connecting portion of the roll sheet holder and the link member,
the roll sheet holder is located at the takeout position when the movable shaft is located at a first position in the guide groove, and
the roll sheet holder is located at the storage position when the movable shaft is located at a second position in the guide groove.

4 . The printer according to claim 3 , wherein the link member supports the opening/closing cover unit at the open position when the movable shaft is located at the first position in the guide groove, and
The link member supports the opening/closing cover unit at the closed position when the movable shaft is located at the second position in the guide groove.

5 . The printer according to claim 3 , wherein the guide groove includes a protrusion, and
the protrusion supports the movable shaft at a third position which is a position between the first position and the second position.

6 . The printer according to claim 5 , wherein the link member supports the opening/closing cover unit at the support position when the movable shaft is located at the third position in the guide groove.

7 . The printer according to claim 6 , wherein the movable shaft passes over the protrusion formed in the guide groove when the opening/closing cover unit starts movement from the support position to the closed position.

8 . The printer according to claim 1 , wherein the printer is able to be set in a first set posture in which the roll sheet input port faces a top side and a second set posture in which the roll sheet input port faces a front side, and
the opening/closing cover unit is opened and closed in an up-down direction about a rear end thereof in the first set posture, and is opened and closed in a front-rear direction about a bottom end thereof in the second set posture.
