A tape cassette includes a cassette case, a tape roll, an ink ribbon, an arm portion, a long hole, and a ribbon take-up spool. A first distance, which is a length of the long hole in a left-right direction, is larger than a second distance, which is a length from a right side surface of the cassette case to a right side end portion of the long hole. A center of gravity of the tape cassette is located in a specific area, which is an area whose both end positions in the left-right direction are the same as both left and right side end portions of the long hole, and which extends in a front-rear direction of the cassette case. The right side end portion of the long hole is located further to the right than a center of the ribbon take-up spool.

Proposed is a dye-sublimation printer, and more particularly to a dye-sublimation printer that can systematically control upward and downward movements of a pick-up roller, upward and downward movements of a platen roller, and driving of a take-up reel gear according to forward and backward movements of a slide plate.

A thermal-transfer printer including a movable member and a head holder, is provided. A first axis of the movable member is located to be closer to a second side of the thermal-transfer printer in an orthogonal direction than a first center being a position of a center of a first spool, and higher than a lower-end position, which is lower than the first center and a second center being a position of a center of the second spool, and is apart from the first center and the second center for a half distance being a predetermined distance divided equally by two. A second axis being a pivot axis of the head holder is located to be closer to the first side in the orthogonal direction than the first center, closer to the second side in the orthogonal direction than the second center, and higher than the lower-end position.

A thermal-transfer printer, including a first case, a second case, an ink ribbon supporting member, a cover, and a head holder, is provided. The first case has a first opening on an upper side thereof. The second case is located on the upper side of the first case and attached movably to the first case to open and close the first opening. The second case includes a second opening on an upper side thereof and a third opening on a lower side thereof. The ink ribbon supporting member is attached to one of the first case and the second case. The cover is attached movably to the second case to open and close the second opening. The head holder is attached to the inner face of the cover and holds a printing head.
