【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, the cassette 50 is configured to be insertable into and removable from the printing apparatus main body B. The cassette 50 includes a pay-out reel 3 and a take-up reel 4, and also includes a head cover 51. The take-up reel 3 and the take-up reel 4 project from the cassette 50 in one direction, and the head cover 51 also projects in the same direction. The feeding reel 3 and the take-up reel 4 are rotatably mounted on the cassette 50, and the feeding reel 3 is mounted with a roll of the ink ribbon Y.

As shown in FIG. 2, the head cover 51 has a U-shaped front face, and has an open surface 55 that is open on the lower side. The ink ribbon Y mounted on the feeding reel 3 is wound around the open surface 55 of the head cover 51, rises along the outer wall of the head cover 51, and is wound around the upper end of the head cover 51 again to be wound up. The reel 4 is mounted so as to be wound up. As a result, the open surface 55 of the head cover 51 is covered with the ink ribbon Y.

The printing head 1 is mounted on the printing apparatus main body B side so as to project in one direction in a cantilever structure, and when the cassette 50 is mounted, the printing head 1 is fitted inside the head cover 51, and the printing surface thereof is 15 is exposed on the open surface 55 side of the cassette 50. Further, a support shaft 30 of the take-up reel 3 and a drive shaft 40 of the take-up reel 4 are mounted on the printing apparatus main body B. As shown in FIG. 3, when the cassette 50 is mounted, the take-up reel 3 and the take-up reel 3 respectively. 4 is configured to be fitted inside. The drive shaft 40 is configured to be rotationally driven by a drive mechanism (not shown).

As shown in FIG. 3, a fastener 41 is attached to the tip of the drive shaft 40 to fasten the drive shaft 40 and the take-up reel 4 so that the take-up reel 4 also rotates as the drive shaft 40 rotates. Has become. As shown in FIG. 4, the support shaft 30 is configured to only penetrate the delivery reel 3, and the delivery reel 3 is configured to rotate with respect to the support shaft 30.

As shown in FIGS. 1 and 5, a cassette chuck 52 is provided between the support shaft 30 and the drive shaft 40 in the printing apparatus main body B, and the cassette chuck 52 is fitted into the projection 53 on the cassette 50 side. Is designed to be fixed.

In the above configuration, with the cassette 50 removed, the roll of the ink ribbon Y is mounted on the delivery reel 3, and the end of the ink ribbon Y is pulled out and wound around the open surface 55 of the head cover 51. Further, it is wound around the upper end of the head cover 51 and then fixed to the take-up reel 4. In this state, the cassette 50 is attached to the printer body B. That is, the print head 1 is fitted inside the head cover 51, the support shaft 30 and the drive shaft 40 are penetrated into the pay-out reel 3 and the take-up reel 4, respectively, and the take-up reel 4 and the drive shaft are driven by the fastener 41. Fix 40. At the same time, the cassette 50 is pushed toward the main body B of the printing apparatus, and the projection 53 is fitted and fixed to the cassette chuck 52.

In this state, the printing head 1 is inside the head cover 51 as shown in FIG. 2, the printing surface 15 thereof faces the open surface 55 side, and the ink wound around the open surface 55. It is in contact with or close to the ribbon Y. In this state, a predetermined operation, that is, if the printing head 1 is a wire dot head, printing is performed on the object through the ink ribbon Y by driving the wire or by heating in the case of a thermal head.

FIG. 6 shows an example in which the above cassettes 50 are arranged in multiple stages. In this embodiment, a plurality of printing heads 1 for thermal transfer are provided on a vertical surface Z of the printing apparatus main body B so as to project in the horizontal direction. The printing head 1 is movable in the vertical direction, and the printing head 1a in the traveling direction of the printing material X (right direction in the figure) can be moved to the highest position. 1b, 1c, 1d are sequentially lower positions. The elevation rail 10 is cut out on the elevation surface Z of the printing apparatus main body B, and one side portion of the printing head 1 is supported by the elevation rail 10 so as to be capable of raising and lowering. That is, the printing head 1 is cantilevered and supported on the vertical surface Z. Each printing head 1 is locked by a predetermined locking mechanism at the highest position and the lowest position of the elevating rail 10, and printing is performed on the printing material X at the lowest position. . The highest position is the retreat position of the print head 1, and the ink ribbon Y is mounted.

A cassette 50 shown in FIGS. 1 to 5 is removably attached to each printing head 1. When the printing head 1 is at the highest position, the cassette 50 is attached to the head cover 51 for printing. It accommodates the head 1. Then, by lowering the printing head 1 from the highest position to the lowest position, the ink ribbon Y is pulled down together with the printing head 1 and extended to the lowest position, and the printing target X is printed at the lowest position of the printing head 1. Is configured to print to.

With such a configuration, it is possible to easily perform, for example, multicolor printing in a short time. Moreover, by using the cassette 50, it is possible to easily mount and replace a plurality of ink ribbons Y 1, and there is an advantage that the mounting space efficiency is improved.

As described above, according to the configuration of the above-described embodiment, the cassette 50 can be easily removed, and the ink ribbon Y can be easily attached and replaced, so that the operability of the printing apparatus is improved and the operation is performed. The rate can also be improved. Further, there is an effect that a multistage arrangement as shown in FIG. 6 can be realized.

[Effect of device]

 As described above, the cassette of the printing medium in the printing apparatus of the present invention includes a print head provided on the printing apparatus side, a cassette body that is attached to and detached from the printing apparatus, and a printing medium attached to the cassette body. And a supporting device that supports the print medium so that the print medium is positioned on the print surface of the head when the cassette body is mounted on the printing device side, so that the print medium can be easily mounted and replaced. It also has the effect of improving operability.
