By the way, since the double feed separation device of the paper selection device described above sends out multiple types of paper, the thickness of the paper may vary, and if the paper is thick, this double feed separation device Paper jams may occur in the rollers of the printer, and if the paper is thin, the rollers may not make sufficient contact with the paper, making it impossible to reliably separate the two sheets.

[Means for solving problems]

Means for solving the above problems in the present invention are as follows:
As shown in FIG. 1, the paper selection device 40, which is controlled by the host device 30 and selects and sends one sheet of paper from a plurality of types of paper based on paper information from the paper information generation means 36, is provided with a pair of rotating It has rollers 33 and 34 with different speeds,
In the double feed separation device 35 of the paper selection device that runs the paper between the pair of rollers 33 and 34 and separates a plurality of supplied papers, the pair of rollers 33 and 34, and a roller position adjusting means 38 for adjusting the roller position based on the determination by the interval determining means.

[Effect]

In the paper double feed separation device according to the present invention, the interval determining means determines the interval between the rollers according to the type of paper on which printing is performed based on the paper information, and the roller position adjusting means determines the interval between the rollers based on this determination. Since the position of the rollers is adjusted using the double feed separation device, the distance between the rollers of the double feed separation device is always appropriate depending on the type of paper.

(Example) Hereinafter, an example of a double feed separation device of a paper selection device according to the present invention will be described based on the drawings.

FIG. 2 shows an embodiment of the double feed separation device of the paper selection device according to the present invention. In this embodiment, the double feed separation device will be explained by taking as an example a device attached to a passbook certificate issuing machine 16 of a passbook certificate issuing system as in the conventional case.

The paper selection device 40 holds a plurality of types of passbook certificate paper 17, which are paper, in a case 18 for each type, and the control device 19 selects the type of passbook certificate designated by the transport device 20 according to instructions from the host computer 15. Paper 17 is conveyed one by one to a printer 22 via a double feed separation device 21, and this passbook certificate paper is printed by the printer 22 and sent to a stacker 23 as a passbook certificate. be.

This double feed separation device 21, like the conventional one, passes two sheets of passbook certificate paper 17° and 17° that have been conveyed through between two rollers 24 and 25 that rotate in opposite directions, and shifts the two sheets of passbook certificate paper 17° and 17°. The certificate papers 17 and 17' are separated and only one passbook certificate paper 17 is sent to a regular conveyance path 26, and the other passbook certificate papers 17° are sent to a conveyance path 27 that carries them to a reject case 28. .

In the double feed separation device 21 according to this embodiment, the host computer 15 is used as a printing paper information generating means, and the printing paper information includes printing selection information and the speed of that type of printing paper (weight of 1000 sheets of printing paper). ) is sent to the control device 19, for example, 90 kg or 135 kg. In this embodiment, the controller operates as a spacing determining means to determine the proper roller spacing. In other words, if the spacing between the rollers is too small for thick printing paper that runs at a high speed, it will not be able to pass between the rollers. In the case of printing paper, it has been decided to reduce the distance between the rollers accordingly.

Based on the determination by the control device, a roller moving device 29, which is a roller position changing means that moves the position of one of the rollers 24, 25 and adjusts the interval between the rollers, operates to change the position of the rollers. change. Specifically, this roller moving device 29 is constituted by a known driving means such as a screw device driven by a motor.

Therefore, in this embodiment, the host computer 15
The control device 19 conveys the designated passbook certificate paper to the transport path 20 based on the printing command, and the control device 19 adjusts the distance between the rollers 24 and 25 based on the information regarding the speed of the passbook certificate paper sent by the host computer. Decide and
Since the roller moving device 29 positions the rollers 24 at determined intervals, it is possible to obtain the optimum roller interval for the passbook certificate paper to be printed, and there is no possibility of paper jams occurring at the rollers. Furthermore, even if the passbook certificate paper is thin, the two passbook certificate papers can be reliably separated.

Incidentally, in the above embodiment, the printing paper information obtained from the host computer as a host device is related to the speed of the printing paper, but this information may be any other quantity as long as it is related to the thickness of the paper. Good too. Furthermore, in the above embodiment, the double feed separation device is applied to a securities certificate issuing device, but the double feed separation device according to the present invention can also be applied to other devices that handle multiple types of paper, such as an OCR device. [Effects of the Invention] As explained above, according to the present invention, the distance between a pair of rollers is determined based on the paper information from the paper information generation means in the double feed separation device of the paper selection device. Since the roller position adjustment means is provided with a distance determining means for adjusting the distance between the rollers and a roller position adjusting means for adjusting the distance between the rollers based on the determination of the distance determining means, it is possible to obtain the optimum distance between the rollers for the selected paper, and to adjust the distance between the rollers. This has the effect that paper jams do not occur, and even when the sheets are thin, the rollers reliably come into contact with the two sheets of paper and the sheets can be separated reliably.
