Description

TECHNICAL FIELD The present application relates to a bill and card identification device in a vending machine or the like in which bills and cards can be inserted in common.

2. Description of the Related Art Conventionally, a bill and card identification device in a vending machine or the like in which a bill and a card can be inserted in common has been disclosed in, for example, Shoukaisho 63-
No. 114370 is known, and this known one is
Two sensors are arranged in the width direction of the insertion slot, when the light transmission of both sensors is blocked, it is identified that the insert is a banknote, and when the light transmission of both sensors is not blocked, the insert Is a card, and the identification signal controls the restriction guide plate to distinguish between the bill passage and the card passage, and the conveyor belt is operated to convey the bill and the card. Further, when the light transmission of any one of the sensors is blocked, the conveyance of the insert is blocked.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, according to the above-described known identification device, when inserting a bill into the insertion slot, for example, when the front corner is bent and does not block the light transmission of both sensors, Regardless of whether the insert is a banknote, it is identified as a card, and the control guide plate forms a path for the card, which may damage the banknote or cause the banknote to be jammed in the transport section. There is an inconvenience such as the presence or absence of the banknote being conveyed because only one sensor is blocked from transmitting light.

Therefore, in order to eliminate the disadvantages of the above-mentioned conventional ones, the present application has an optical identification means for identifying the width of a banknote and a card in the vicinity of an insertion opening in which a banknote and a card can be commonly inserted. A banknote and card discriminating apparatus comprising: a restriction guide plate that is activated by the discrimination signal to discriminate between the bill passage and the card passage; and a conveyor belt that is activated by the discrimination signal. From the first and second optical sensors for identifying the width of the banknote, and the third optical sensor located between the first and second optical sensors for identifying the width of the card by the first optical sensor. The third optical sensor is configured such that the light transmission is blocked by the card, but the light transmission is not blocked by the double thickness of the banknote.

When the card is inserted into the insertion opening, the card conceals the first and third optical sensors at the same time.

Then, the third optical sensor with high luminous intensity is blocked by the thick card from transmitting light together with the first optical sensor, and only the second optical sensor transmits light. Therefore, when the first and third optical sensors are turned off, the insert is inserted into the card. Is detected, and the conveying belt is actuated by this discrimination signal, and the limiting guide plate is projected to form a passage for the card, and the card is conveyed to, for example, the card processing mechanism.

Further, when the bill is inserted into the insertion opening, the bill intervenes in its full width and conceals the first, second and third sensors at the same time.

Then, the translucency of the first and second sensors at the left and right positions is blocked by the concealment of the bill, but the light of the third optical sensor at the intermediate position having high luminous intensity is transmitted, and therefore, the light of the first and second photosensors is transmitted. When it is turned off, it is identified that the insert is a banknote, and based on this identification signal, the conveyor belt runs and the restriction guide plate holds the retracted state, so the banknote is conveyed by the conveyor belt to, for example, the banknote identification processing unit. To be done.

In the above case, since the light transmission of the third optical sensor at the intermediate position is not blocked, there is no fear that the insertion object is erroneously identified as a card.

Also, if the front corner of the bill is bent and the double-thickness portion intervenes at the position of the third optical sensor at the intermediate position, even in this case, the double-thickness portion of the card still remains. Since it is thinner than the material thickness, light transmission is allowed, and therefore, in this case as well, there is no misidentification as a card.

Embodiments Hereinafter, embodiments of the present application will be described in detail with reference to the drawings.
The figure is a plan view of the identification device communicating with the transport mechanism,
As shown in FIG. 2, the insertion opening (2) located in front of the housing (1) constituting the identification device has a receiving opening (2) a corresponding to the length of the short side of the banknote A and its It has a receiving port (2) b corresponding to the length of the short side of the card B, which is offset to the right side, and three optical sensors are provided in the vicinity of the insertion port portion (2) in the width direction. (3), (4), and (5) are arranged at regular intervals.

In the figure, an optical sensor (3) at the right position and an optical sensor (4) at the intermediate position are optical sensors for identifying that the insert is the card B, and the optical sensor (3) at the right position and the left position. The optical sensor (5) of (1) is an optical sensor for identifying that the insert is a banknote A. In the present application, the light intensity of the optical sensor (4) at the intermediate position is blocked by the card B, but The light intensity is set so that the light transmission is not blocked by the double thickness of the bill.

(6) is a conveyor belt for conveying bills and cards,
(7) is a limit guide plate that can be retracted to limit the conveyance width from the passage of bills to the passage of cards. In the normal state, it is in a retracted state so as to allow the passage for conveyance of bills, and the insert is the card. When it is identified, the identification signal is projected to limit it to the card transport path. (8)
Is an electromagnetic solenoid that prevents the conveyance of bills and cards by operating a shutter when each sensor does not operate normally, and (9) to (11) are magnetic heads for discriminating between bills and cards.

Then, when the card B is inserted from one of the receiving ports (2) b, the card B intervenes in a state of being offset to the right side of the housing (1) as shown by the phantom line in FIG. ) And (4) are hidden at the same time.

Then, light transmission is blocked together with the optical sensor (3) by the card B which is thicker than the optical sensor (4) having a high luminous intensity, and only the light of the optical sensor (5) is transmitted, so that the optical sensors (3) and (4) are transmitted. When it is turned off, the insertion object is identified as the card B, and the identification signal activates the conveyor belt, and the limiting guide plate (7) protrudes to form a passage for the card B. It is transported to the processing mechanism.

Further, when the banknote A is inserted into the other receiving port (2) a, the banknote A intervenes in the full width of the passage of the housing (1) and the optical sensors (3), (4 ),
Conceal (5) at the same time.

Then, the light sensors (3) and (5) at the left and right positions are blocked from transmitting light due to the concealment of the bill, but only the light sensor (4) at the intermediate position having high luminous intensity is transmitted, and therefore the light sensors ( By turning OFF 3) and (5), it is identified that the insert is a banknote, and from this identification signal, the conveyor belt (6) runs and the restriction guide plate (7) keeps the retracted state. The banknote A is conveyed by the conveyor belt (6), for example, to the banknote identification processing section.

In the above case, since the light transmission of the optical sensor (4) at the intermediate position is not blocked, there is no possibility of misidentification that the insert is the card B.

Further, if the front corner of the banknote A is bent and the double-thickness portion intervenes at the position of the optical sensor (4) at the intermediate position, even in this case, the double-thickness portion still remains. Since the material thickness of the card B is smaller than that of the card B, light transmission is allowed. Therefore, in this case also, the card B is not mistakenly identified.

Effect of the Invention Since the present application is configured as described above, it is possible to correctly identify whether the insert is a banknote or a card, and the banknote has, for example, a bent corner portion. Even when the identification device is inserted into the insertion opening, it is possible to provide a highly reliable identification device without the risk of misidentification.
