Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a roll paper cutting device suitably used in game machines such as fortune-telling machines found in game arcades, for example.

BACKGROUND OF THE INVENTION In the gaming machine described above, necessary information is printed on roll paper using a printer built into the housing of the gaming machine, and the paper is fed through a roll paper path to a take-out port. Since a cutter is provided in the passage, the player pulls the roll paper that has come out from the outlet and cuts it with the cutter to obtain cut pieces of the roll paper on which predetermined information is printed.

In this case, pull the tip of the roll paper at the outlet to ensure that the roll paper can be cut with the cutter.
The path of the roll paper is bent, and a cutter is provided from inside the bend toward the inside of the path.

A conventional roll paper cutting device of this kind is disclosed in Japanese Utility Model Application No. 131252/1983. As shown in Fig. 4, the path d from the feed roller b built into the printer a to the roll paper outlet c is bent by providing a hood e with an arcuate inner surface. A cutter f is provided from the inside of the bent portion toward the inside of the passage.

If the cutter f is installed in such a position, when the tip of the roll paper g is pulled at the outlet c, the roll paper g will come into contact with the cutter f, so that the roll paper g will be securely removed as described above. It can be cut.
In the figure, h is a roll of paper g, which is built into the housing i of the game machine together with the printer a.

Problems to be Solved by the Invention Incidentally, the above-mentioned conventional device has the following problems.

In other words, in order to cut the roll paper, the leading edge of the roll paper must be fed to the take-out port c, but since the roll paper has a tendency to curl, it ends up curling up in the path and cannot reach the take-out port. Sometimes it doesn't come out. Therefore, there is a problem in that it becomes impossible to pull the roll paper to cut it at the outlet.

However, this kind of problem is not unique to gaming machines, but rather devices that use cutters to cut roll paper by pulling it out through a path with cutters (such as cash registers).
This is a generally common problem.

In order to solve the above problem, the length of the path should be made as short as possible so that the leading edge of the roll paper comes out to the ejection port before the paper rolls up into a circle. Since the length of the path becomes extremely short, the path cannot regulate the direction in which the roll paper is pulled, so depending on the direction in which the roll paper is pulled, the roll paper may not come into contact with the cutter, and the roll paper may be cut. A contradiction arises when it is impossible to do so.

In view of these points, the present invention provides a useful means that prevents the roll paper from curling up in the path even if the path of the roll paper has the necessary length in order to regulate the direction in which the roll paper is pulled. is intended to provide.

Means for Solving the Problems In order to achieve the above object, the present invention is such that the roll paper path from the roll paper delivery drive unit to the take-out port is bent, and the roll paper is In those equipped with paper cutting cutters,
Ribs for regulating the curl of the roll paper extending along the feeding direction of the roll paper are provided on the upper and lower wall surfaces of the roll paper path leading from the cutter to the take-out port, at positions facing the vicinity of the center in the width direction of the roll paper surface. It is characterized by the provision of.

Embodiment FIG. 1 shows a rolled paper cutting device applied to a fortune-telling machine as an embodiment of the present invention, in which 1 is a housing of the fortune-telling machine, 2 is a rolled paper body supported within the housing 1, and 3 is a rolled paper cutting device. This is a printer that prints predetermined information on roll paper 4 that is fed out from rotating body 2. The printer 3 is mounted on a printer mounting plate 5 supported within the housing 1. A notch 5a corresponding to the paper width of the roll paper is formed at the upper end of the mounting plate 5, and the roll paper fed out from the roll 2 is supplied into the printer 3 through this notch. Although not shown in the drawings, a roller, an arc-shaped jig, a U-shaped jig, etc. is provided at the bottom of the notch 5a to improve the slippage of the roll paper 4 and to smoothly supply it into the printer 3. ing.
The printer 3 is equipped with necessary printing mechanisms such as a printer head 3a, and a feed roller 3c as a drive unit for feeding the roll paper through an outlet 3b.

An opening 7 is formed in a part of the upper surface plate 1a of the housing 1, and a pair of guide plates 7a and 7b extend substantially horizontally from the periphery of the opening toward the inside of the housing 1. Both guide plates 7a and 7b form passage walls, and a part of the roll paper passage A is formed within the opposing interval. The roll paper path A is from the outlet 3b of the printer 3 to the roll paper outlet 8. The roll paper outlet 8 is located further outward than the opening 7 by attaching a cover plate 9 having an inverted U-shaped cross section to the periphery of the opening 7 as shown in the figure.
Further, the extending end of the lower guide plate 7a is positioned above the outlet 3b of the printer, and the upper guide plate 7b
The passage A is bent by providing the guide body 10 standing up between the extending end of the printer 3 and the printer 3. Ao in the figure is the bent part. and,
A roll paper cutting cutter 11 is provided inside this bent portion Ao toward the inside of the passage A. 12
A mounting plate for mounting the cutter 11 is provided on the printer mounting plate 5 at positions on both the left and right sides where it does not interfere with the guide plate 7a. The guide body 10 is configured to be movable upward, and by moving upward, the inside of the passage A can be inspected and the roll paper 4 can be easily pulled out for the first time.

A passage wall (including the upper and lower guide plates 7a, 7b and the cover plate 9) between the cutter 11 and the outlet 8 is provided with a rib 13 for regulating the curl of the rolled paper. In this embodiment, the rib 13 is provided at approximately the center position in the width direction of the upper and lower guide plates 7a and 7b along the roll paper feeding direction. Also rib 1
3 may be provided with two or more.

If the above-mentioned ribs 13 were not provided at all, the roll paper 4 would wind up in a circle in the passage A due to the curling tendency of the roll paper itself, as shown in FIG. 13, the roll paper 4 is folded into a mountain shape in the width direction of the roll paper while straddling the ribs 13 as shown in FIGS. 2A and 3. 4. Curling along the longitudinal direction is effectively prevented. In the above case, the curl of the roll paper 4 is controlled exclusively by the lower rib 13, but in consideration of the fact that the roll paper 4 with the opposite curl may be applied, the upper and lower ribs are It is best to have ribs on both sides. In addition, in this roll paper cutting device, in particular, the ejection guide section of the roll paper 2 is made narrow to prevent the user from inserting his/her fingers into the ejection port 8 of the roll paper 2 and touching the cutter 11 and injuring himself. The roll paper 2 is formed into a hollow shape, but if such a structure is adopted, the roll paper 2 is
Guide at an acute angle to the first cutting edge is a necessary condition for making a smooth cut.

Therefore, the roll paper 2 fed out from the outlet 3b of the printer 3 is bent by the guide body 10 and the upper guide plate 7b and guided to the discharge guide section, but inevitably the roll paper 2 is bent by the upper guide plate 7b. Since it comes into contact with the plate 7b, the degree of adhesion increases due to static electricity, friction, etc., and a jam may occur.

In such a case, the rib 13 on the upper guide plate 7b
By providing this, the roll paper 2 is effectively prevented from coming into close contact with the upper guide plate 7b, and as a result, the occurrence of jams is reliably prevented. rib 1
The height of No. 3 can be appropriately determined in order to obtain a predetermined curl correction effect. And the upper and lower ribs 13, 13
When the distance between the two is set to a predetermined value or less, the upper rib 13 effectively prevents the roll paper from curling. Further, the rib 13 may be provided over the entire length from the cutter 11 to the outlet 8, but even if it is not the entire length, as long as it can prevent the rib from curling in the passage,
It does not matter if the length is less than that. Furthermore, the rib 13 does not need to be provided at the center position in the width direction on the upper and lower walls of the passage; as long as the rib 13 is at a position opposite to the vicinity of the center in the width direction of the rolled paper surface to be fed out, no support will be provided at all even if the rib 13 is slightly shifted to the edge. do not have. The generation of jams is reliably prevented. Further, as described above, a plurality of them may be provided. As a method of providing the ribs 13, the guide plates 7a, 7b (cover plate 9
If a rib is provided on the guide plate 7a, it may be formed integrally when forming the cover plate 9 (including the cover plate 9), or the rib itself may be manufactured separately and then attached to the guide plate 7a with adhesive or welding, etc. It does not matter if it is fixed to 7b. Moreover, instead of the upper guide plate 7b forming the passage A and the guide body 10 in an upright state,
It is also possible to use a hood e like the conventional example shown in FIG.

Effects of the Invention As explained above, according to the roll paper cutting device according to the present invention, by providing a rib for adjusting the curl of the roll paper on the passage wall between the cutter and the take-out port, the roll paper can be cut in the passage. This has the excellent effect of effectively preventing roll paper from getting caught.

In addition, since ribs are simply provided on the passage walls, the structure is simple and inexpensive to implement, and the present invention also has practical effects such as being easy to apply to conventional roll paper cutting devices. .
