本発明は、ラベルプリンタの台紙巻取機構に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mount winding mechanism for a label printer.
従来の技術
従来、ラベルプリンタにおいては、スペルが剥離された
台紙を巻取るための台紙巻取機構が設けられており１台

れている。BACKGROUND OF THE INVENTION Conventionally, label printers have been provided with a mount winding mechanism for winding up the mount from which the spelling has been peeled off.A typical example of a mount winding mechanism is shown in FIG. 9. . That is, a cylindrical mount winding core 2 is connected to a drive shaft 1 that rotates around its axis, and a mount pressing groove 4 for inserting a mount presser 3 is formed on the outer peripheral surface of the mount winding core 2. ing. When the mount presser 3 is inserted into the mount presser groove 4, the end portion of the mount is held down by the mount presser 3. Note that the mount presser 3 is formed in such a size that it protrudes from the outer circumferential surface of the mount take-up core 2 when inserted into the mount presser groove 4 .
台紙巻取コア２に巻取られた台紙の取外しは、台紙押え
３を台紙押え溝４から抜取り、台紙の内径を弛ませた後
に行なっている。The mount wound around the mount winding core 2 is removed after the mount presser 3 is removed from the mount retainer groove 4 and the inner diameter of the mount is loosened.
発明が解決しようとする問題点
台紙押え３を台紙押えＷＩｔ４から抜取る際の操作性が
悪く、また、台紙がきつく巻回されているために抜取り
に手間がかかつている。さらに、台紙押え溝４から抜取
った台紙押え３を紛失する場合もある。Problems to be Solved by the Invention The operability when removing the backing sheet presser 3 from the backing sheet presser WIt4 is poor, and since the backing sheet is tightly wound, it takes time and effort to remove it. Furthermore, the mount presser 3 removed from the mount presser groove 4 may be lost.
問題点を解決するための手段
略半円筒状の一対の巻取コアを一側を回動自在に結合し

アの内部に回動自在に設ける。Means for Solving the Problems A pair of substantially semi-cylindrical winding cores are rotatably joined at one side to form a cylindrical shape, and a one-way clutch is attached to a drive shaft connected to the winding cores. An operating lever is rotatably provided inside the winding core to bias the winding core in the diametrically expanding direction when the winding core is rotated in the mount winding direction.

ーを台紙巻取方向と逆方向に回動させる際ワンウェイク
ラッチの逆転防止作用により巻取コアの回転が阻止され
、巻取コアの縮径操作を簡単に行なえる。The operating lever is rotated to rotate the winding core in the diameter-expanding direction, and the mount is wound around the winding core in the diameter-expanded state. When removing the mount from the winding core, the operating lever is rotated in the direction opposite to the winding direction of the mount to release the biasing force applied to the winding core in the diameter expanding direction, thereby reducing the diameter of the winding core. When the operating lever is rotated in the opposite direction to the liner winding direction, the one-way clutch prevents rotation of the winding core, and the diameter reduction operation of the winding core can be easily performed.

り駆動軸１４は回転停止状態に維持されている。When winding up the mount 25, the operating lever 20 is rotated to the state shown in FIGS. 6 and 7, and the cam portion 22 is brought into pressure contact with the cam pressure contact portion 6. Due to this pressure contact, the winding core 5 rotates in the radially expanding direction about the fulcrum shaft 18 as a fulcrum. and,
When the winding core 5 is expanded to the maximum outer diameter, one of the operating lever stoppers 23 comes into contact with the winding core stopper 7, and the operating lever 20 is prevented from rotating further counterclockwise. ing. Further, the end of the mount 25 is wound around the winding core 5 by sandwiching the end of the mount 25 between the mount pressing plate 13 and the mount pressing groove 11, as shown in FIG. Then, when the operating lever stopper 23 further rotates the operating lever 20 in contact with the winding core stopper 7 counterclockwise after pinching the end of the mount 25, the winding core 5, rotating shaft 16, etc. They rotate integrally in the counterclockwise direction, and the initial winding of the mount 25 around the winding core 5 is performed. Note that at this time, the drive shaft 14 is maintained in a rotationally stopped state by the action of the one-way clutch 15.

れる。After completing the initial winding of the mount 25 around the winding core 5, a label 26 is issued. When issuing this label, the drive shaft 14 rotates counterclockwise, and the one-way clutch 1
The rotating shaft 16 and the winding core 5 are integrally rotated counterclockwise via the winding core 5, and the mount 25 is wound onto the first winding core 5.

時計方向への回動も阻止される。Next, when removing the mount 25 wound around the single-winding core 5, the operating lever 20 is rotated clockwise from the state shown in FIGS. 6 and 7. By this rotation operation, the cam portion 22
is separated from the cam pressure contact portion 6, and the winding core 5 is rotated in the diameter reduction direction about the fulcrum shaft 18 by the biasing force of the ring 12, so that the outer diameter of the winding core 5 is reduced. As a result, the mount 2
The inner diameter of the winding core 5 is slack, and the mounting paper 25 can be easily removed from the winding core 5. Further, when removing the mount 25, there is no need to remove the mount presser plate 13 from the winding core 5, and there is no risk of loss. Note that when the operating lever 20 is rotated clockwise, only the operating lever 2o is rotated due to the anti-reverse action of the one-way clutch 15, and the clockwise rotation of the first take-up core 5 and the like is prevented. When the cam portion 22 is completely separated from the cam pressure contact portion 6, the operating lever stopper 2
4 comes into contact with the winding core stopper 7, and the clockwise rotation of the operating lever 20 is also prevented.

失を防止することができる等の効果を有する。Effects of the Invention Since the present invention is configured as described above, the outer diameter of the winding cam can be increased or decreased by rotating the operating lever, and when the mount is removed from the winding core, the winding core The inner diameter of the mount can be loosened by reducing the diameter of the winding core, and when the operating lever is rotated to reduce the diameter of the winding core, the rotation of the winding core is prevented by the reversal prevention action of the one-way clutch, and the operating lever is rotated. Only the rotation can be operated,
Therefore, it is possible to easily remove the mount from the winding core, and it is possible to prevent parts from being lost when the mount is removed.
