Abstract

PROBLEM TO BE SOLVED: To prevent mischief by the forcible opening of the closed sheet sheet material conveyance path when sending an abnormality signal out when detecting a lever for shutter position detection not being at its fixed position when a driving device stops. SOLUTION: On a card conveyance path 2, the shutter device 23 which opens and closes the card conveyance path 2 is arranged. When a stepping motor 5 as the driving device stops, a sensor 29 for shutter position detection judges whether or not the tip parts 27a and 28a of levers 27 and 28 for shutter position detection are at a position X to send an OFF signal to a controller when the above-mentioned tip parts 27a and 28a are not at the position X and an ON signal when the tip parts 27a and 28a reach the position X. The controller when judging that the sensor 29 for shutter position detection is not ON sends a driving signal out to an abnormal state informing means. The abnormal state informing means sends out the abnormality signal for interrupting the process of a card reader writer 21.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card or banknote in which various information storage or recording areas are formed,
The present invention relates to a sheet material conveying path for conveying a sheet material such as a gift certificate, and more particularly to an improvement of a shutter device for opening and closing the sheet material conveying path.

[0002]

2. Description of the Related Art Conventionally, there has been proposed a card in which various information recording or storage areas such as a magnetic recording area and an IC storage area are formed on a card which is one of sheet materials, and information is written on such a card. Alternatively, a card reader / writer is provided as an apparatus for performing processing such as reading.

This card reader / writer reciprocates a card inserted in a card insertion slot from an upstream (card insertion slot side) to a downstream of a card conveyance path by card conveyance means such as conveyance rollers provided therein. During the transport, a process of writing or reading information to or from each information storage or recording area of the card is performed.

On the other hand, in the above card reader / writer,
If another card or the like is continuously inserted from the card insertion slot while the inserted card is being processed, the card processing will be disturbed. To prevent this, a card communicating with the card insertion slot is to be prevented. A shutter device for opening and closing the card transport path is provided in the middle of the transport path to prevent another card from being inserted during card processing.

FIG. 9 is a sectional view of a main part of a conventional shutter device 3 of the card reader / writer 1 described above. Also,
10 to 13 are cross-sectional views of main parts of the card reader / writer 1 showing the operation of the shutter device 3, and the same parts as those in FIG.

As shown in FIG. 9, the shutter device 3
A shutter lever 4 for opening and closing a card transport path 2 formed in a direction perpendicular to the drawing, a stepping motor 5 for rotating the shutter lever 4, and a control device (not shown) for controlling the operation of the stepping motor 5. It is configured.

In this shutter device 3, the shutter lever 4 is fixed to the drive shaft 6 of the stepping motor 5, and the drive of the stepping motor 5 causes the shutter lever 4 to move from the stop position in FIG. By rotating the shutter lever 4 by a predetermined angle in the counterclockwise or counterclockwise direction, the leading end portion 4a of the shutter lever 4 is projected into the card transport path 2 and is removed therefrom, thereby closing or expanding the card transport path 2.

According to such a shutter device 3, in the standby state of the shutter lever 4 shown in FIG. 9, the shutter lever 4 causes the tip 4a of the shutter lever 4 to escape from the inside of the card transport path 2 and expands the card transport path 2. Is being planned.

When the card insertion is detected by a sensor (not shown) disposed upstream of the card conveyance path 2 in the expanded state of the card conveyance path 2, the card is disposed along the card conveyance path 2. The card is conveyed along the card conveyance path 2 by the card conveyance means 8 including a roller 7 and a conveyance belt (not shown), and passes through the shutter device 3.

When a sensor (not shown) disposed downstream of the card transport path 2 detects that the rear end of the inserted card has passed through the shutter device 3, the control device (not shown) operates. In response to the drive signal, as shown in FIG. 10, the shutter lever 4 is driven by the stepping motor 5 to rotate 90 ° clockwise (in the direction of arrow A) about the shaft 6 from the stop position in FIG. 9 as shown in FIG. The leading end 4a of the shutter lever 4 projects into the card transport path 2 to close the card transport path 2 to prevent the next card from entering.

In the shutter device 3, when the card processing of the inserted card is completed, and when the card processing is detected, the shutter lever 4 is moved from its stopped position through the control device (not shown) as shown in FIG. A 90-degree rotation in the counterclockwise direction (the direction of arrow B) causes the distal end portion 4a of the shutter lever 4 to escape from the card transport path 2 as shown in FIG. Return to.

As described above, in the conventional shutter device 3,
The card transport path 2 is opened and closed by the shutter lever 4 to prevent another card or the like from being continuously inserted from the card insertion slot while the inserted card is being processed.

[0013]

According to the conventional shutter device 3 described above, as shown in FIG.
The shutter lever 4 is a driving shaft 6 of a stepping motor 5.
However, since the shutter lever 4 cannot detect whether or not the shutter lever 4 has rotated from the rotation position, for example, during card processing, when the card transport path 2 shown in FIG. When a tool or a foreign object is forcibly inserted into the card transport path 2 from a card insertion slot (not shown), the shutter lever 4 is rotated about the shaft 6 as shown in FIG. Rotating in the counterclockwise direction (direction of arrow B), the leading end 4a of the shutter lever 4 escapes from the inside of the card transport path 2 as shown in FIG. 13, and the closed card transport path 2 is forcibly expanded. There was a possibility that it would be done.

In the conventional shutter device 3, since the stop position of the shutter lever 4 cannot be detected, the card transport path 2 is closed when the card transport path 2 is closed.
Cannot be detected, the card once conveyed into the card conveyance path 2 is forcibly pulled out from the card insertion slot, or another card is forcibly inserted during card processing. Thus, the mischief of obstructing various processes such as reading and writing on the card cannot be prevented. Note that a bill processing device that handles bills as sheet materials,
Alternatively, a similar problem has been raised in a gift certificate processing device that handles gift certificates.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and provides a shutter device for a sheet material conveyance path which prevents mischief based on forcible opening of a closed sheet material conveyance path as much as possible. Aim.

Next, the processing procedure of the control device 31 will be described with reference to the flowchart of FIG. In the standby state of the card reader / writer 21, as shown in FIG. 1, the shutter lever 4 has its tip 4a escaped from the card transport path 2 to open the card transport path 2, and waits for the insertion of a card. (Step 100).

At this time, of the shutter position detecting levers 27 and 28, the shutter position detecting lever 28
Has reached the position X of the shutter position detecting sensor 29.

On the other hand, the control device 31
It is determined whether or not a card has been inserted from the card insertion slot by the first card detection sensor 40 disposed upstream of the system (step 101). Is repeated.

On the other hand, when the insertion of a card is detected by the first card detection sensor 40 in step 101, the control device 31 drives the card transport means 8 to transport the inserted card along the card transport path 2. (Step 102).

Next, it is determined whether or not the card has passed the shutter device 23 based on the output signal of the second card detection sensor 41 provided downstream of the shutter device 23 (step 103). If it is determined that the card has not passed through the shutter device 23, the process of step 103 is repeated until the control device 31 determines that the card has passed the shutter device 23.

On the other hand, if it is determined in step 103 that the card has passed the shutter device 23, the control device 31 sends a pulse signal to the stepping motor 5, and based on the number of pulses of the pulse signal, the control device 31 returns to FIG. As shown, the stepping motor 5 is driven to move the shutter lever 4 clockwise from the stop position shown in FIG.

Reaches the position X where the shutter position detecting sensor 29 is disposed.

On the other hand, when the shutter position detecting lever 27 reaches the position X, the control device 31 determines whether or not the shutter position detecting sensor 29 is ON (step 105). 29 is ON
If it is determined that the position is not the same, the tip portion 27a of the shutter position detection lever 27 has not yet reached the position X, that is, the shutter lever 4 has not been rotated until the card transport path 2 is normally closed. Then, the processing after step 104 is performed.
Repeat until is turned ON.

On the other hand, when it is determined in step 105 that the shutter position detecting sensor 29 is ON, the tip 27a of the shutter position detecting lever 27 has reached the position X, that is, as shown in FIG. Thus, it is determined that the shutter lever 4 has normally closed the card transport path 2,

Thus, the shutter lever 4 and the shutter position detecting levers 27 and 28 also start to rotate clockwise (in the direction of arrow D) about the drive shaft 6 (step 111).

Next, the controller 31 determines whether or not the shutter position detecting sensor 29 is ON (step 1).
12) If it is determined that the shutter position detecting sensor 29 is not ON, the tip end 28a of the shutter position detecting lever 28 has not reached the position X, that is, the shutter lever 4 normally expands the card transport path 2. It is determined that it has not been rotated until it is opened, and the processing from step 111 is repeated until the shutter position detecting sensor 29 is turned on.

On the other hand, if it is determined in step 112 that the shutter position detecting sensor 29 is ON, the tip end 28a of the shutter position detecting lever 28 is moved to the position X.
That is, the controller 31 determines that the shutter lever 4 has normally opened the card transport path 2 as shown in FIG. 1, and then the controller 31 stops driving the stepping motor 5 (step 113). The transport means 8 is driven in a direction to eject the card (step 114).

Then, the control device 31 determines whether or not the card has been ejected based on the detection signal of the first card position detecting sensor 40 (step 115). The subsequent processing is repeated until it is determined that the card has been ejected.

On the other hand, if the controller 31 determines in step 115 that the card has been ejected,
Is stopped (step 116), and the process returns to step 101 and subsequent steps.

That is, the shutter device 23 having the above configuration
