Description

Description: FIELD OF THE INVENTION The present invention relates to an automatic teller machine, and in particular, by detecting the thickness of a banknote in two stages, an unfit note is received from the customer. The present invention relates to a cash-receipt-type automatic cash deposit / payment device that does not pay an unfit note.

[Background of the Invention]

In recent years, financial institutions such as banks, securities companies, and post offices have been increasingly equipped with automatic teller machines for labor saving of window operations. However, it has been difficult to identify bills that have been spoiled by tape or the like that can be easily identified by visual inspection.

As a device for detecting such a modified bill, there is a device described in Japanese Utility Model Publication No. 60-5422, for example. This is because when the bill is conveyed while contacting the roller, the roller vibrates due to the thickness of the bill, and when the other end of the detection lever changes, the change speed including the pickup changes rapidly. It is detected by a detector. Further, when the tape is spliced in the width direction of the banknote by the above method, the conveyance path is rotated by 90 ° in the middle, and the second detector having the same structure as above is used to tape the banknote in the longitudinal direction. It is also possible to detect when they are spliced together.

However, in the above method, not only the thickness of the tapes spliced together, but also the dust may simply adhere to the bills or the folded bills may be detected. That is,
No consideration is given to making the displacement detection level variable, and it is indistinguishable from the case of wrinkles and folds of banknotes and two-ply banknotes.

Furthermore, in the cash-receipt-and-disbursement system, the banknotes that have wrinkles and folds are clearly distinguished from the banknotes that are spliced together with tape, etc. Since it has been separated, it is distinguished from banknotes that are spliced together with tape (hereinafter referred to as unfit banknotes), and only those that have wrinkles or folds are used as return banknotes for payment, and the folds are simply separated. Banknotes (damaged notes) should not be used for payment, and modified banknotes of insufficient length should be returned immediately.

[Object of the Invention]

The object of the present invention is to solve such a conventional problem, when a customer deposits an unfit note, it is received, when paying the unfit note to the customer, this is blocked, and a modified bill is deposited. Occasionally, it is to provide an automatic teller machine that is capable of surely distinguishing and detecting from other unfit bills.

[Outline of Invention]

In order to achieve the above object, the automatic teller machine of the present invention has a deposit opening for accepting banknotes inserted by a customer, a dispensing slot for paying banknotes to the customer, and the authenticity of bills at the time of depositing and dispensing, money. In an automatic teller machine equipped with a discrimination means for discriminating between a type and a loss, a storage box for storing a genuine note by denomination as a result of the discrimination, and a storage box for storing an unfit note, further depositing and withdrawing money. A means for determining the destination of the banknote based on the comparison result by comparing the displacement output value of the thickness detecting means and the reference level with the thickness detecting means that sometimes detects the thickness of the banknote and outputs a displacement according to the thickness. And, it has a reference level setting means for setting the reference level to be high at the time of deposit and low at the time of withdrawal, and to change the destination of the bill by changing the reference level for determining the thickness of the bill at the time of deposit and withdrawal. There are features.

The pick-up portion 18 of the displacement detector 17 detects the movement of the detection lever 14 of the thickness detecting mechanism, the displacement is amplified by the amplifier 19, and the output is given as one input of the level comparator 24.
When the operation mode setting unit 20 issues a deposit 26 or dispense 27 command, the reference level setting unit 21 sets the level A or the level B, and the set output is given as the other input of the level comparator 24. The level comparator 24 compares the output of the displacement detector 17 with the reference level of the level A or the level B, and inputs the result to the determination unit 25, so that the determination unit 25 determines the destination to which the banknote 1 should be conveyed. .

Next, the overall operation will be described with reference to FIG.

When the customer inserts the banknote 1 into the deposit unit 2, the deposit unit 2
Then, the banknotes 1 are separated one by one, and the banknotes 1 are transferred to the thickness detection mechanism 3 by the transfer mechanism. 2 banknotes transported 1
In the case of banknotes that are piled up and spliced with tape or the like, or wrinkles and folded banknotes, one end of the detection lever 14 is displaced left and right, and the displacement detector 17 is displayed as shown in FIGS. Produces the output shown. As shown in FIG. 3A, since the judgment level of the output signal at the time of deposit is high, only the two banknotes 1 shown in (e) are returned to the dispensing port 5 through the transport mechanism 11, and wrinkles The destination of the folded bill 1 is determined according to the discrimination result of the discrimination unit 4. In the discriminating section 4, the banknote 1 which discriminates the authenticity, the denomination, and the damage, and is determined to be invalid is returned to the outlet 5 through the transport mechanism 11, and among the banknotes 1 determined to be valid, The genuine bills are stored in the storage units 6 to 8 according to the denominations of A, B, and C, and the unfit bills are stored in the unfit bill storage unit 9.

Next, at the time of withdrawal, the banknote 1 is paid out from one of the storage units 6 to 8 for A, B, and C, and the thickness detection mechanism 3 is conveyed by the transport mechanism 11.
Be transported to. As shown in FIG. 3B, since the judgment level of the output signal at the time of withdrawal is low, the repaired banknotes that are overlapped with two sheets and joined by tapes, etc. Be transported. The other banknotes 1 are discriminated by the discriminating section 4, and the banknotes 1 that are determined to be invalid are also conveyed to the reject box 10, and only the banknotes 1 that are determined to be valid pass through the conveying mechanism 11 to the dispensing port 5. Be transported.

〔The invention's effect〕

As described above, according to the present invention, the judgment levels at the time of depositing and withdrawing are made variable, the threshold value is high at the time of depositing, and the threshold value is low at the time of dispensing, so the customer You can deposit the unfit note and you will not be paid the unfit note when you receive the payment.
