DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a take-up reel device which is used, for example, to sequentially take up printed journal paper in a journal printer or to take up backing paper in a label printer.

[0002]

2. Description of the Related Art An example of a conventional journal printer having a thermal printer configuration will be described with reference to FIGS.
The journal printer 1 is used, for example, in an electronic cash register, in addition to a receipt printer 2, and has a printing portion in which a line-type thermal head 3 and a platen roller 4 are freely contacted and separated and pressed. They are arranged facing each other. Then, the thermal head 3 is driven while the journal paper 5 made of the roll paper pulled out from the roll body passes between the thermal head 3 and the platen roller 4 of the printing unit through the pair of guide plates 6 and is conveyed by the platen roller 4. Printing is performed. The printed journal paper 5 is sequentially wound up by a winding reel device 8 via a guide plate 7.

As shown in FIGS. 5 and 6, the take-up reel device 8 is fitted with a main reel 10 having a cylindrical core portion 9 so as to be detachably fitted to the core portion 9. The take-up reel 13 has a joining portion 11 and is combined with a sub-reel 12 having a size equivalent to the main reel 10.
The winding core 9 is a portion where the journal paper 5 is wound, and a winding gear 15 is integrally attached to the outside of the main reel 10 on a shaft 14 thereof. The shafts 14 of the main reel 10 and the sub reel 12 are rotatably supported by shaft support portions 18 formed in notches on the device side plates 16 and 17.

A platen gear 21 for the platen roller 4 is connected to the motor gear 19 via the idle gear 20 on the one hand to form a printing section transport drive system.
On the other hand, idle gear 20, detail pulley gear 2
2. The take-up gear 15 is connected via the transmission belt 23, the detail pulley gear 24, and the detail gear 25 to form a take-up section drive system.

With this configuration, the driving force is transmitted to the take-up gear 15 in parallel with the printing operation, and the take-up reel 13 is driven to rotate, so that the journal paper 5 is displaced between the reels 10 and 11. Is wound up on the winding core 9 in a proper manner. The journal paper 5 wound on the core part 9 is freed from the core part 9 by removing the take-up reel 13 from the apparatus side plates 16 and 17 and removing the sub reel 12 from the main reel 10 when necessary. Removed from the edge.

[0006]

However, in the case of such a take-up reel device 8, erroneous insertion of the fitting portion 11 of the sub-reel 12 into the core portion 9 or the main reel 10 side of the take-up reel 13 itself. And the auxiliary reel 12 may be mistakenly mounted on the apparatus side plates 16 and 17, or the like, and a winding failure of the journal sheet 5 may occur. In particular, in the case of the journal paper 5, unlike the case of a used label mount or the like, it is a printed result for confirming the contents later,
It is not preferable that a take-up defect occurs in the take-up reel 13.

In this regard, as shown in FIG.
Is omitted, and the take-up reel 26 is constituted only by the main reel 10 by supporting the shaft 14 of the main reel 10 having the winding core 9 on the apparatus side plate 16 in a slightly inclined state. According to this, although the problem associated with the mounting of the sub reel 12 can be solved, it is difficult to wind up the journal paper 5 in an orderly manner performed by the sub reel 12, and the end of the journal paper 5 may be broken. There is. In particular, when the shaft 14 is tilted, it is difficult to wind it up on the core 9 in an orderly manner. Further, a mechanism for supporting the shaft 14 receiving the drive transmission in an oblique state is likely to be complicated.

Therefore, the present invention has a very simple structure,
It is an object of the present invention to provide a take-up reel device that does not cause a risk of erroneous insertion or the like in mounting the take-up reel, that has a simple drive transmission system, and that can take up an object to be wound in an orderly manner.

[0009]

According to a first aspect of the present invention, there is provided a take-up reel device having, on a shaft, a cylindrical core portion on which an object to be wound is wound, and integrally with the core portion. A main shaft that is rotatably driven, and a shaft supporting portion that is integrally formed with a part of the apparatus side plate and that detachably and rotatably supports one end of the shaft on the side not having the main reel. And a sub reel portion which is larger than the maximum winding diameter of the object to be wound.

Therefore, since the portion serving as the auxiliary reel is formed integrally using a part of the apparatus side plate as the auxiliary reel part, the winding is performed when the main reel having the core is mounted on the apparatus side plate. The take-up reel is completed, and no mounting error such as erroneous insertion of the sub reel occurs. At this time, since the auxiliary reel portion is formed larger than the maximum winding diameter of the object to be wound around the axis, the object to be wound can be wound up orderly to the end. In addition, when the main reel is removed from the side plate of the apparatus, the auxiliary reel portion does not exist, and one end of the core portion remains free, so that the work to be taken up can be removed from the core portion. Easy to do.
At the same time, there is no need to support the main reel shaft or the like at an angle, so the configuration of the drive transmission system is simplified, and the sub reel unit does not require a fitting structure to the core. The configuration is simplified.

In the present invention, the "object to be wound" can be applied to various types of roll paper requiring a winding process, such as the above-described journal paper in a journal printer and a label mount for a label printer. The device side plate on which the sub-reel portion is formed may be a side plate of a portion where a take-up reel device is directly mounted in a printer or the like. As the shaft support formed on this device side plate,
The structure may be such that the shaft is inserted through the notch, or may be a structure such as a round hole shape in which one end of the shaft is attached and detached in the axial direction. It is only necessary to be able to support it freely without any rotation. The auxiliary reel portion may be larger than the maximum winding diameter of the object to be wound around the axis, and may have a substantially circular shape in accordance with the main reel, but may have a rectangular shape or the like. . However, the sub-reel portion does not necessarily have to be entirely planar, and may have, for example, a structure in which a large number of radial slits are formed around the axis.

According to such a configuration, since the portion serving as the sub reel is formed integrally as the sub reel portion 34 by utilizing a part of the apparatus side plate 33, the main reel having the core 9 is formed. Since the take-up reel 36 is completed when 10 is mounted on the apparatus side plates 16 and 33, mounting errors such as erroneous insertion of the auxiliary reel do not occur. At this time,
Since the auxiliary reel portion 34 is formed larger than the maximum winding diameter of the journal paper 5 around the shaft 32, the journal paper 5 can be wound up to the end together with the main reel 10 without any deviation or the like. In a state where the main reel 10 is removed from the apparatus side plates 16 and 33, the auxiliary reel portion 34 does not exist, and one end of the core portion 9 remains in a free state. The work of extracting from the part 9 can be easily performed. At the same time, there is no need to support the shaft 32 of the main reel 10 at an angle, so that the configuration of the drive transmission system including the winding gear 15 and the like is simplified, and A structure for fitting to the core 9 is not required, and the plane structure of the side plate may be used, and the configuration is simplified.

[0015]

According to the first aspect of the present invention, there is provided a main reel which has a cylindrical core portion on which an object to be wound is wound on a shaft and is driven to rotate integrally with the core portion. A shaft support portion integrally formed on a part of the apparatus side plate and supporting a detachable and rotatable one end of the shaft on a side not having the main reel, the winding target object around the shaft. A main reel having a winding core is formed by integrally using a part of the apparatus side plate as a sub-reel part having a sub-reel part larger than the maximum winding diameter of the reel. Since the take-up reel is completed when the reel is mounted on the side plate of the apparatus, there is no occurrence of mounting error such as erroneous insertion of the sub-reel, and the sub-reel portion takes up the object to be wound around the axis. Since it is formed larger than the maximum diameter, you can wind up the winding target Can be further in a state in which removal of the main reel from the apparatus side plates, there is no sub reel unit,
Since one end of the core remains free, it is easy to remove the wound target from the core, and at the same time, the main reel shaft and the like are tilted and supported. Since there is no need to perform any operation, the structure of the drive transmission system can be simplified, and there is no need for the auxiliary reel unit to have a fitting structure with respect to the core, and the side plate plane structure may be used. It can also be simplified.
