DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The width and length of postmarks for stamping stamps affixed to paper sheets are set to optimum values in view of the size of stamps and the visibility to humans. However, the size of the stamper is naturally limited. In the conventional stamping device, as shown in FIG. 11, the sticking range of stamps capable of stamping in the direction of the short side of the paper sheet is a fixed distance C from the lower end of the conveying path to the stamper and the stamp. Due to the width of the imprinter limited by the width D of the mark, it is limited to the range A shown in FIG.

Further, the sticking range of the stamps capable of imprinting in the long side direction of the paper sheets is limited to the range of the distance B in FIG. This is because the length E of the postmark is limited even if the stamping mechanism is controlled so that the postmark can be applied to the stamp as much as possible and the sticking position of the stamp is changed.

Therefore, there is a problem that the stamping process cannot be carried out even if there is even one stamp stuck in the range other than A in the short side direction and in the range longer than B in the long side direction. there were.

The present invention has been made in view of the above points, and it is an object of the present invention to make it possible to imprint paper sheets over a wider range.

[0008]

In order to solve the above problems, in the present invention, a plurality of imprinting means are provided. Then, the sticking position of the stamps stuck on the paper sheets is detected by the detecting means, and each of the stamping means is driven in accordance with the sticking position of the stamps to carry out the stamping.

[0009]

By providing a plurality of imprinting means, the imprintable range is increased. Moreover, since the sticking position of the stamp is detected by the detecting means and each of the imprinting means is controlled accordingly, the imprinting can be surely performed even in a wide range.

[0010]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a first embodiment of the present invention,
In this embodiment, two rotary imprinters having different heights are arranged vertically along the conveying path.

The stamping device according to the present embodiment includes a conveying path 1 for conveying the paper sheets 12, a photoelectric sensor 13 for detecting the leading end of the paper sheets 12, and a detector for detecting the positions of stamps on the paper sheets 12. 1
4, a stamp position determining circuit 15 for determining the final sticking position information of stamps based on the information of the detector 14, and a register 1 for storing the information obtained by the stamp position determining circuit 11.
6, a photoelectric sensor 7 provided on the conveyance path 1 for detecting the leading edge of the paper sheet 12, a counter circuit 17 for starting counting after the photoelectric sensor 7 detects the leading edge of the paper sheet 12, and stored in the register 16. A stamp control circuit 17 for determining stamp driving timing based on the stamp sticking position information and the count value in the counter circuit 8, a drive circuit 20 for driving the stamp 19 and a drive circuit 22 for driving the stamp 21 are provided. There is.

The stampers 19 and 21 are arranged along the sheet conveying path as shown in FIG. 2 and have different heights. The stamper 19 stamps stamps attached at a high position, and the stamper 21
Is in charge of stamping stamps attached at a position lower than the stamper 19.

The detector 14 is provided with a light source that illuminates the paper sheet 12 being conveyed and a light receiving portion that receives the reflected light from the paper sheet 12. The light receiving unit includes a light receiving unit A having a light receiving element for detecting stamps attached within the imprintable range of the stamper 19, and a light receiving unit for detecting stamps attached within the imprintable range of the stamper 21. It is composed of a light receiving portion B having an element. Output signals from the light receiving units A and B are sent to the stamp position determination circuit 15, respectively.

The stamp position determination circuit 15 determines the stamp position based on the signal from the detector 14 and the tip detection signal from the photoelectric sensor 13. As shown in FIG. 3, the paper sheet 12 is conveyed in the direction of the arrow in FIG. 3. At this time, the detection range of the detector 14 is divided into a plurality of areas as indicated by the broken line in FIG. The A-stage in the figure shows the detection range of the above-described light-receiving unit A, and the B-stage shows the detection range of the light-receiving unit B. The numbers 1 to 7 are after the leading edge of the paper sheet 12 is detected by the photoelectric sensor 13. Shows the elapsed time of. The diagonal lines shown in FIG. 3 indicate the areas where stamps are detected, here area A.
6 and area B2 indicate that stamps have been detected.

Next, the operation of the above embodiment will be described. First,
When the paper sheet 12 is conveyed through the conveying path 1, the detector 14
Pass through. On the basis of the signal from the detector 14, the stamp determining circuit 11 determines which area in FIG. 3 the sticking position of the stamp on the paper sheet 12 is. Stamp position determination circuit 11
Is provided with memory means corresponding to each area of FIG. 3, and the memory means of the area to which the stamp position is attached has, for example, "H" (H
igh) signal is set. In the example of FIG. 3, the “H” signal is set in the memories corresponding to the shaded areas A6 and B2.

Since the row A in FIG. 3 corresponds to the stamper 19, the stamper 19 is driven when the counter circuit 17 counts "6" after the leading edge of the paper sheet 12 has passed the photoelectric sensor 7. For example, it is imprinted on area A6 in FIG. Further, the row B in FIG. 3 corresponds to the stamper 21, but since the stamper 21 is on the downstream side of the stamper 19, it is delayed from the count time “2” when the stamp position is detected by the detector 14. It is necessary to drive the stamper 21. The delay time at this time is the time during which the paper sheet 12 is conveyed from the stamper 19 to the stamper 21. Here, the delay time is set to "3", and the data in the column B is counted as shown in FIG. Shift by "3".

Now, the above data (FIG. 4) of the stamp position judging circuit 11 is temporarily stored in the register 16, and after the front end of the paper sheet 12 has passed the photoelectric sensor 7, the counter circuit 17 divides the area of FIG. The time is counted at the same timing as the elapsed time and the imprint control circuit 18 is notified. The stamp control circuit 18 checks the data in the register 16 for each count, drives the stamper 19 when the A-column data is "H", and drives the stamper 2 when the B-column data is "H".
Drive 1 In the case of the example in FIG. 4, the stamper 21 is driven when “5” is counted after the photoelectric sensor 7 detects the leading edge of the paper sheet 12, and the stamper 19 is driven when “6” is counted. Driven.

As described above, according to the above apparatus, by providing a plurality of imprinting devices, imprinting in a wider range becomes possible. In the above embodiment, the stamp detection range is limited to the broken line portion in FIG. 3, but if a detector and a stamper are added, stamping in a wider range is possible. Further, if the number of imprinting devices capable of detecting the entire surface of the paper sheet and imprinting the paper sheet at any position is provided, the stamps can be imprinted over the entire surface of the paper sheet.

FIG. 5 shows a second embodiment of the present invention. In this example, the stampers 31 and 32 having the same height are arranged along the conveying path 1. In the conventional stamping mechanism, when a plurality of stamps are stuck in parallel to the conveying path as shown in FIG. 5, the stamper stamps the first stamps and makes one revolution while the paper sheets are rotated. Moves on the transport path, so one stamper
It was difficult to imprint a plurality of postmarks by rotating them more than once. However, according to this embodiment, since a plurality of imprinting devices are driven, imprinting can be performed even in the above case. The circuit configuration of the second embodiment is similar to that of FIG.

The detection range of stamps in the case of the second embodiment is as shown by the broken line in FIG. 6, for example. The numbers 1 to 7 are the same as in the first embodiment and indicate the elapsed time after the photoelectric sensor 13 detects the leading edge of the paper sheet 13. In the first embodiment, the detection range has two steps A and B, but in the second embodiment, the two stampers have the same height, so the detection area has one step.

Assuming that stamps are attached to the shaded areas "2" and "6" in FIG. 6, the stamp 31 is responsible for imprinting the stamps (area "6") on the rear side and the stamps on the front side. The stamper 32 is in charge of stamping stamps (area "2"), allocates a memory for each stamper, and sets "H" in the area to which the stamp is attached (see FIG. 7). At this time, assuming that the interval between the stampers 31 and 32 is the same as that in the first embodiment, the data for the stamper 32 is shifted backward by "3" as shown in FIG. After that, the stamper 31, based on the data of FIG.
32 is driven. That is, the photoelectric sensor 7 is the paper sheet 1.
When the counter circuit 17 counts "5" after detecting the leading edge of 2, the stamper 32 is driven, and when the counter circuit 17 counts "6", the hour stamper 31 is driven.

FIG. 8 shows a third embodiment of the present invention, in which an ink jet type imprinting means is used as the imprinting means. Two or more inkjet printer heads 40 in the vertical direction from the transport path (five in FIG. 8)
Only the ink droplets at the necessary positions are ejected from the nozzles according to the stamp sticking position information which is arranged and detected by the detector to perform the stamping. As a result, stamps can be stamped in a wider range as in the case of the rotary stamper.

Further, according to the above-mentioned ink jet system, continuous imprinting can be carried out over a wide range without the time loss that is seen in a rotary type imprinter such as once imprinting cannot be imprinted until one revolution. it can. In addition,
The nozzle of each inkjet may be of a single nozzle type or a multi-nozzle type. Further, in the above embodiment, a plurality of ink jet printer heads are used side by side, but if there is a head capable of printing in a wide range with one head, then one such head may be used to construct the imprinter. .

Further, a rotary type stamper can be added to the above-mentioned ink jet type stamping device. FIG. 9 shows an example of the postmark when both are used in combination (fourth embodiment). According to this embodiment, the rotary type stamper has the station name
There is an advantage that the control of the inkjet becomes simpler by imprinting the date and using the inkjet type stamper exclusively for the wave stamp for the purpose of preventing the reuse of stamps.

[0025]

As described above, according to the present invention, by arranging a plurality of imprinting means and controlling them separately,
Stamps can now be stamped on areas that could not be stamped.
