Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a medium detection mechanism provided in a receipt or card conveyance path in a slip creation device such as a deposit machine.

Bank terminals, e.g. cash dispensers,
In slip creation devices such as automatic deposit machines, a credit card is inserted into a card slot, and after processing withdrawals or deposits, certain items are printed on paper and the embossed part of the credit card is imprinted to create a receipt. The device is equipped with a slip creation device which is stored in the device as a copy and the other part is ejected as a receipt into a card slot together with the credit card and returned to the customer.

In such devices, media such as receipts and credit cards are transported using a guide plate, and the media are run using this guide as a transport path. Generally, in detecting the running of a medium on such a transport path, if the running direction of the medium is always constant, a simple lever mechanism is provided, and this lever mechanism is operated by the medium, and the lever is activated. Travel of the medium can be detected by monitoring the movement with a sensing element. However, if the direction of travel is not constant, as in the case of a credit card in such a device, where the credit card is inserted and ejected through one transport path, the detection mechanism becomes complicated.
There was a problem with the price.

Therefore, conventionally, in order to detect the movement of a medium on such a conveyance path, photo sensors are placed above and below the conveyance path, and detection is performed by blocking light as the medium passes. Alternatively, detection was performed by directly applying the actuator of the microswitch to the medium and operating the microswitch.

However, in the former case, the receipt as a medium generates paper dust, and this paper dust and dirt and dust in the air reduce the light intensity of the photo sensor, causing a failure that prevents detection output from being obtained. do. The drawback was that it required constant cleaning. In the latter case, it is sufficient if the medium is always a constant solid body, but in order to detect a soft material such as a receipt, there is a problem in that the adjustment is delicate and the reliability is lowered.

The purpose of the present invention is to eliminate the above-mentioned problems, and includes a lever that protrudes in a conveyance path formed by a guide plate that conveys a medium, an elastic material that neutralizes the lever in the protruded position, and A rotatable roller is locked to a protrusion of the lever so that the lever can be rotated in any direction with respect to the reciprocating conveyance of the medium. This is achieved by a medium detection mechanism consisting of:

The present invention will be described in detail below with reference to the accompanying drawings.
FIG. 1 shows an overview of the slip creation device, particularly the outline of the slip printing mechanism and conveyance mechanism. A customer inserts a credit card 17 in the longitudinal direction into a card slot 1 provided protruding from the front of the device. At this time, shutter 2
Since the card is not opened, it is inserted through the card passage gap in the shutter 2. In this state, the card is sent out in the direction of arrow A along the card transport path 3A by rollers R1, R2, R3, and R4.
Next, the credit card 1 is transferred to the card reader/writer section 16.
7 is sent in, and the recorded contents of the credit card are read by the magnetic head MH and roller R5.
Furthermore, it is sent out from the card reader/writer section 16,
It is sent to the table mechanism 4 by rollers R6 and R7. On the other hand, the slip printing mechanism feeds out the continuous paper 11 stored in the paper feed section 12 in the direction of arrow B by feeding out the tractor TR, and sends it out to the printer section. In the printer section, print head 9 and platen 1
The paper 11 is sandwiched between the paper 11 and the printing head 9, and characters corresponding to the processing content are printed on the paper 11 using a printing method in which the transport direction of the paper 11 is the line feed direction. The printed paper 11 is a journal 11A and a receipt 11B.
The upper surface of the rotary blade 7 of the cutter part 8 is passed through the journal 11A, the lower surface is passed through the receipt 11B, and the receipt 11B is cut by the rotary blade 7 and the fixed blade 6. In the imprinter section 5, the cut receipt 11
B and journal 11A are overlapped again, and paper 1
1, and then the credit card 17 sent to the table mechanism 4 is rotated 90 degrees with the table mechanism 4 as shown by the dotted line, taken in, overlapped with the paper 11, and pressed against the roll 5' of the imprint unit 5. . As a result, the embossed display symbol of the credit card 17 is copied onto the paper 11. After copying, the journal 11A, receipt 11B, and credit card 17 are usually separated, and the journal 11A is moved by rollers R8, R9,
It is guided by R10, transported in the direction of arrow C, and wound into the winding section 13. Receipt 11B is roller R
11, R12, R13, R14, and R15, the card is transported in the direction of arrow D, guided by the gate 14, passes through the transport path 3B, opens the shutter 2, and is transported to the card slot 1 by rollers R1 and R2. is discharged. The credit card 17 is sent out from the table mechanism 4 by rollers R6 and R7 in the direction of arrow A', which is the opposite direction to the direction at which it was inserted.The credit card 17 is processed and recorded by the card reader/writer section 16, and transferred to the rollers R3 and R7.
4, R1, and R2, the card is discharged to the card slot 1. In this case, the credit card 17 and the receipt 11B are discharged at the same time. Therefore, when the credit card 17 and the receipt 11B are ejected, the line flicker 10 provided in the card slot 1 is blinked, the shutter 2 is opened, and the line flicker 10 is turned off as soon as the customer completes taking out the receipt 11B and the credit card 17. stops blinking and closes shutter 2. However, if something unusual occurs after inserting the credit card 17 into the card slot 1, in other words, if the credit card 17 is read by the card reader/writer section 16, but it is different from the accepted credit card 17, immediately return the card to the card slot. It is returned to 1. In addition, if an abnormality occurs during processing, after copying the imprint unit 5, the receipt 11
B is rollers R11, R12, R13, R14, R
15 in the direction of arrow D, and by switching the gate 14 clockwise and counterclockwise, the paper is transported along the transport path 3C in the direction of arrow E', and is stored in the reject box 15A by rollers R19. .
Next, the credit card 17 is transferred to the table mechanism 4.
From rollers R11, R12, R13, R14, R
15 in the direction of arrow D, and the gate 1
4 is returned to the state shown in the figure and sent out in the direction of arrow E.
It is stored in the redirect box 15B.

Conventionally, a detection mechanism for detecting the running of the medium is installed on the conveyance path of such a device.
A photo sensor is used. That is, photo sensors are provided above and below the conveyance path 3A, and the photo sensors detect the insertion of the credit card 17 or the ejection of the credit card 17 and the receipt 11B. Furthermore, photo sensors are also installed on the conveyance routes 3B and 3C, and in the case of the conveyance route 3B, it is confirmed that the receipt 11B is sent out, and the shutter 2 is
Operate the opening of the line and the blinking of the line flicker. or,
In the case of the conveyance path 3C, the medium is detected using many photo sensors, such as confirming that the receipt 11B has been stored in the redirect box and proceeding to the next operation. However, photo sensors have to be constantly cleaned because they suffer from problems such as dust and dirt that reduce the detection output.

FIG. 2 shows a detection mechanism for detecting the running of a medium according to the present invention. In FIG. 2, a is a front view and b is a side view of the medium detection mechanism according to the present invention. The medium is conveyed through the space formed by the side plates 3' and 3'' as a conveyance path.As shown in a, the detection mechanism includes a roller 20A, a lever 20B, a shaft 20F, a spring 20D, a magnet 20G, and a Hall element 20C.
It is composed of: The lever 20B has a shaft 2 whose central part is fixed to a fixed surface 20E such as a frame.
0F, a roller 20A is rotatably connected to one end, and a magnet 20C is fixed to the other end. A spring 20D is stretched between the lever 20B and the shaft 20F, and with this spring 20D,
The roller 20A is always located at a medium passing position on the conveyance path, and the lever 2B is kept neutral so as to be perpendicular to the conveyance path. The Hall element 20C is fixed at a position close to the magnet 20G fixed to the lever 20B when the lever 20B is in the neutral position. Therefore, as shown in b, when the medium is conveyed in the direction of the arrow A, the roller 20A and the lever 20B are rotated about the shaft 20F, respectively, to 20A' and 20B' indicated by dotted lines.

Therefore, the magnet 20G, which had been close to the Hall element 20C, moves. Therefore, the Hall element 20C can be changed from OFF to ON.
When the medium further passes, the lever 20B and the roller 20
A is the spring 2 in the neutral position shown by the original solid line.
It returns with an elastic force of 0D. When the medium is conveyed in the direction of arrow B, the roller 20A and the lever 20B are rotated to 20A'' and 20B'', respectively, but the Hall element 20C can be turned from OFF to ON as described above. Therefore, by monitoring the output of the Hall element 20C, the traveling of the medium can be detected, and the advantage is that the traveling direction of the medium can be detected in either the direction of arrow A or the direction of arrow B. There is.

As explained above, in the present invention, the lever 20B is held neutral by the spring 20D, and the lever 20B is
This is a simple medium detection mechanism in which by bringing one end of 0B into contact with the medium and rotating a lever 20B, a Hall element 20C is turned on and off by a magnet 20G fixed to the other end. Therefore, compared to the detection mechanism of a conventional photo sensor, troubles caused by dirt and dust are eliminated, and since the mechanism is simple, it can be made inexpensive.
