DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transfer printer such as a label printer that prints a product name or a barcode on a label using a transfer ribbon.

[Prior Art] For example, a ribbon device used in a label printer that prints barcodes is equipped with a pair of ribbon set shafts, and the transfer ribbon fed out from one of the set shafts passes through the printing section. Then, it is wound around the other ribbon set shaft.

The pair of ribbon set shafts are removably attached across opposing frame side plates of the ribbon support frame. Transfer ribbons, which are consumable items, are removably supported on these ribbon set shafts.

A winding core fixing means is provided at one end of the ribbon set shaft, and a winding core fixing means is provided at the other end. One end of the core of the transfer ribbon is removably fitted into the core fixing means, and this fitting stops the core from moving in the radial and axial directions with respect to the ribbon set shaft.

The winding core removal stop means is removably engaged with the other end surface of the winding core, and clamps the winding core between the winding core fixing means and prevents movement of the winding core toward the other end side of the ribbon setting shaft. is prevented. Therefore, the winding core is supported by the ribbon set shaft through both of these means, and is arranged to rotate together with the ribbon set shaft.

The winding core fixing means and winding core removal stopping means provided at the end of the ribbon set shaft are both immovable, and the interval between these means corresponds to the width of the transfer ribbon to be used. Was. Therefore, it was not possible to adjust the interval.

[Problems to be Solved by the Invention] Currently used transfer ribbons have widths of 2 inches, 3 inches, 4 inches, and 6 inches. However, as described above, conventionally, ribbon set shafts are dedicated to the transfer ribbons used, so transfer ribbons with widths that are compatible with paper of various widths to be printed on can be placed on the same ribbon set shaft. The problem is that it cannot be installed on the Note that, for example, when using a transfer ribbon with a width of 4 inches, it is possible to print on paper with a width smaller than that using a part of the transfer ribbon.

However, in that case, a large amount of transfer ribbon is wasted.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transfer printer that can use a transfer ribbon having a width suitable for various paper widths and that does not waste transfer ribbons.

[Means for Solving the Problems] In order to achieve the above object, in the transfer printer of the present invention, the winding core of the transfer ribbon is attached to one end of the ribbon set shaft that supports the transfer ribbon in the radial and axial direction. A winding core fixing means is provided on the other end side of the ribbon set shaft to gradually open radially outward from the one end side toward the other end side, and a winding core fixing means is provided on the other end side of the ribbon set shaft. At least one winding core fixing means and the winding core fixing means are provided on the ribbon set shaft and are located between the winding core fixing means and the winding core removing means on the ribbon set shaft. and is provided with at least one positioning means, and is positioned by the positioning means and detachably attached to the ribbon set shaft, and the winding core remover supports another winding core shorter than the winding core together with the stop means. It is equipped with auxiliary fixing means.

[Function] In the present invention, the distance between the winding core fixing means at one end of the ribbon set shaft and the hooking part of the winding core removal stopping means at the other end has a width close to the axial length of the ribbon set shaft. Matches the length of the transfer ribbon and its core. Therefore, when using a transfer ribbon of the above width attached to a ribbon set shaft, the ribbon core should be fitted onto the ribbon set shaft from the winding core fixing means side toward the winding core fixing means. As a result, one end of the winding core is supported by the winding core fixing means, and the other end of the winding core is engaged with a hooking part of an arm constituting the winding core fixing means. Thereby, the winding core is held between the two means by the elastic force of the arm, and the transfer ribbon having the above width is attached to the ribbon set shaft. In this case, no auxiliary fixing means are used.

The auxiliary fixing means is used when attaching a transfer ribbon narrower in width than the transfer ribbon to the ribbon set shaft. In this case, prior to attachment of the narrow transfer ribbon, the auxiliary fixing means is positioned on the positioning means previously provided to fit the ribbon and attached to the ribbon set shaft. With this attachment, the auxiliary fixing means is located closer to the winding core fixing means than the core fixing means, and the distance between the auxiliary fixing means and the engagement part of the arm is smaller than the width of the narrow transfer ribbon. Matches the length of the core.

Therefore, by fitting this winding core onto the ribbon set shaft from the side of the winding core removal stop means toward the auxiliary fixing means, one end of this winding core is supported by the auxiliary fixing means, and the winding core is The other end is engaged with the engagement part of the arm. Thereby, the winding core is held between the auxiliary fixing means and the winding core removal stop means by the elastic force of the arm, and the narrow transfer ribbon is attached to the ribbon set shaft.

Since at least one means for positioning the auxiliary fixing means with respect to the ribbon set shaft is provided, if there are multiple means, transfer ribbons of widths corresponding to those positions are attached as described above. be able to.

Therefore, printing can be performed by attaching transfer ribbons of various widths.

These removal stop means 71 and 72 have the same structure and are formed by a pair of arms 73 disposed between the shaft body 65 on both sides in the radial direction. Each arm 73 can be elastically deformed, and gradually separates from the shaft body 65 as it goes from the one end side to the other end side of the shaft body 65 and opens radially outward. Moreover, the winding core 62 is provided at the tip of the arm 73.
A hooking portion 74 that is hooked to the other end is formed.

The shaft body 65 has one positioning means 7 located between the winding core fixing means 66 and the second winding core removing means 72.
5 is provided. This positioning means 75
It is formed of a flange having a diameter larger than 5, and in this embodiment, it has the same diameter as the winding core support 68, and also serves as a winding core support.

Further, the shaft main body 65 is provided with a winding core support 76 located between the first and second winding core removal stop means 71 and 72, and a winding core support 76 that is positioned between the second winding core removal stop means 72 and 72. A winding core support 77 is provided between the means 75 and the winding core support 77 . These winding core supports 76 and 77 are both formed of flanges and have the same diameter as the winding core support 68.

Furthermore, the shaft portion 65a between the positioning means 75 and the winding core support 77 in the shaft body 65 has a circular cross section as can be seen from FIGS. 1 to 5 excluding FIG.
A part of the upper side portion 78 (in FIGS. 1 to 5 except FIG. 2) is cut away. Reference numeral 79 indicates the notch.

It is attached to the ribbon set shaft 47. In this installation state, the single-shaped groove portion 84m at the upper part in FIGS. Since the auxiliary fixing means 81 is fitted into the T-shaped section formed by the ribbon set shaft 47, the auxiliary fixing means 81 will not come off inadvertently in the direction perpendicular to the axis of the ribbon set shaft 47.

After this, the 2-inch wide core 62' is attached, and the procedure is the same as the above-mentioned installation of the 4-inch wide core 62. This is done by fitting toward the 66 side.

Then, one end of the winding core 62' is attached to the auxiliary fixing means 8.
1 and is fitted into the winding core support 82 thereof, and a notched groove (not shown) at the end of the winding core 62' is fitted into the protrusion 83. At the same time, when the second winding core is removed, the engaging part 74 of the arm 73 forming the stop means 72 is connected to the winding core 6.
Since the arm 73 protrudes from the other end of the winding core 62' and expands due to its elastic force, its engaging portion 74 elastically engages the other end of the winding core 62'.

Therefore, as shown in FIG. 5, the winding core 62' is held between the auxiliary fixing means 81 and the second winding core stopper means 72, and is attached to the ribbon setting shaft 47. In this state, the intermediate portion of the winding core 62 is supported by the winding core support 77 from inside.

The winding core 62' can be removed from the ribbon set shaft 47 in the same manner as the long winding core 62 described above.
The explanation will be omitted.
