Description

[Detailed explanation of the invention] [Industrial application field] This invention allows the issuance of various cards such as parking tickets and other admission tickets continuously without interruption for reasons such as replenishment of paper or connection. Regarding improvements to card issuing machines that can be made, more specifically,
The present invention relates to a card holding device suitable for use in this type of card issuing machine.

[Conventional technology] Roll paper made of card paper rolled into a roll, etc.
Conventional card issuing machines issue cards by printing and cutting while sequentially pulling out card paper from a pack of fan-hold paper that is thinly formed to make it easier to cut the cut line, but they run out of roll paper or pack paper. Therefore, card issuance had to be suspended until new card paper could be reset or connected. However, the card issuing machine related to Utility Model Application No. 60-64902 (Utility Model Application No. 180356/1983) proposed earlier by the present applicant requires interruption of card issuance due to replenishment of card paper, connection, etc. This made it possible to issue cards continuously.

That is, the card issuing machine according to the above application has a card supply passage leading to a card issuing passage divided into left and right branches, and card paper can be freely supplied to each of these supply passages from a respective roll paper or pack. When the card paper supplied from one supply path runs out, the feed of the drive roller (feed roller) is switched, and the other paper that was inserted between the drive roller and the tension roller in advance is inserted between the drive roller and the tension roller. The system is designed to continue issuing cards by sending card paper from the supply path.

[Problem to be solved by the invention] However, the card paper in the other supply path, which is held between the drive roller and the tension roller, is Since the card paper is held between both sides of the drive roller and tension roller by force alone, if for some reason an external force is applied to the card paper while it is waiting, the card paper sandwiched between the two rollers will be damaged. There were cases where the card fell out and the card issuing was interrupted when switching.Also, when switching the card paper feed, if the surface of the card paper is smooth and slippery, or if the card paper is thin There was also a problem with the drive rollers slipping and not properly delaying the card stock.

Therefore, the technical problem of the present invention is to securely hold the waiting card paper inserted between the drive roller and tension roller so that it will not easily fall off due to external force. The purpose of the present invention is to not only clamp the paper but also allow the card paper to be smoothly and accurately fed without causing the driving roller to slip during feeding.

[Means for solving problems]

The measures taken in the present invention to solve the above technical problems are as follows.

A supply passageway leading to a card issuing passageway equipped with transport rollers is formed into two branches on the left and right, a tension roller is provided in each of these card supply passageways, and the feeding surface is approximately half-shaped in the middle of both card supply passageways. A drive roller formed in the shape of an arc-shaped cam disk is provided, and when it is detected that the paper supply from either one of the card supply paths has stopped, the motor rotates the drive roller, and the feed surface of the drive roller is rotated. In a card issuing machine configured to continue issuing cards by feeding the card paper from the other supply path, the tip of which has been inserted in advance between the tension rollers, to the transport rollers of the issuing path, the above-mentioned drive A recess into which the tension roller bites is provided on the feeding surface of the roller.

However, the drive roller herein means a roller that transports the card paper held between the tension roller and the card paper to the card transport roller in the card issuing path that communicates with the supply path.

[Effect]

The above means works as follows.

According to the above means, when card paper is being supplied from one card supply passage toward the card issuing passage, the card paper in the other card supply passage is held between the drive roller and the tension roller. When the paper supply from one card supply path stops, the drive roller rotates and sends the held card paper to the issuing path, and the card transport rollers feed the card, that is, issue the card. You can continue. In this invention, in particular,
The circumferential surface of the tension roller bites into the recess in the feeding surface of the drive roller, thereby firmly holding the card paper sandwiched between them and preventing the card paper from falling out due to external forces and slipping of the drive roller. To prevent.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the above-mentioned conventional technology can be solved.
