Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a banknote validating device that does not process test banknotes as normal banknotes even if an erroneous operation occurs.

Automatic deposit machines and the like have a bill validating section, and this bill validating section discriminates bills inserted into the deposit machine for various items.

The discrimination results obtained for each item are then notified to the control unit along with the strobe signal.

Deposit machines may also be tested using test banknotes.

Since test banknotes do not have all the characteristics of normal banknotes, when a test banknote is inserted into a deposit machine, the banknote validator will judge the test banknote to be counterfeit, and as a result, the test banknote will always be returned. I end up.

For this reason, when testing a deposit machine using test banknotes, the discrimination result signal for a certain item from the banknote discrimination unit is invalidated, and the test discrimination result signal generated by the test discrimination result signal generation unit is The result signal is sent to the control unit.

Specifically, when a test banknote is used, the 1,000 yen denomination output, the 5,000 yen denomination output, and the 10,000 yen denomination output of the banknote validating device are all logic "O".

Of course, in the case of normal banknotes, the denomination output is "1".

Therefore, when testing, all of the above denomination outputs are disabled.

Then, the test discrimination result signal generating section generates the test thousand yen denomination signal, test 5,000 yen denomination signal, or test ten thousand yen denomination signal of logic "1", and generates the test denomination signal of logic "1". A denomination signal is sent to the control unit using a strobe indicating that the test bill output from the discrimination unit has been read.

However, if the test discrimination result signal is erroneously left unsent to the control unit during the normal mode of the deposit machine, the deposit machine will process the counterfeit banknotes as genuine banknotes.

The present invention is based on the above consideration, and is configured such that a test banknote is not processed as a normal banknote even if the test recognition result signal is output from the test recognition result signal unit in the normal mode. The purpose is to provide a bill validating device.

Therefore, the bill validating device of the present invention outputs a strobe every time a bill that can output various types of discrimination result signals is inserted, and also discriminates the bill and outputs a denomination signal during the period in which the strobe is output. In the bill validating device that sends out to the control section, means is provided for specifying the denomination of the bill at the time of the test, and when the denomination is specified and the control section is in the test mode, the bill is generated in accordance with the inserted test bill. The strobe is characterized in that a designated denomination signal is sent to the control unit.

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a diagram showing the internal structure of a banknote bulk insertion type automatic teller machine, which is one of the fields of application of the present invention, in which 1 is a banknote bulk insertion slot, 2 is a banknote return slot, 3 is a banknote suction belt, and 4 , 5 is a bill return belt, 6 is a bill retrieval device, 7 is a suction tube such as a vacuum wheel, 8 is a roller, 9 is a conveyor belt, 10 is a roller, 11 is a bill validator, 12 is a bill storage belt, 13 is a gate.

The banknotes B inserted into the banknote bulk insertion slot 1 are carried to a predetermined position by the banknote suction belt, and are inserted one by one between the conveyor belts 9, 9 by the banknote removal device 6.

The banknote retrieval device 6 as a whole rotates counterclockwise,
The suction tube 7 rotates clockwise.

The banknotes inserted into the conveyor belts 9, 9 are passed through the banknote discrimination section 11.
tfflJ by.

The banknotes that have passed through the discrimination section 11 are further carried by belts 9, 9, and then inserted between rollers 10, 10.

When the bill is determined to be defective, the gate 13 is pushed to the left and the defective bill is carried to the return slot 2.

If the banknote is normal, the gate 13 is pushed to the right,
Normal banknotes are discharged onto the belt 12.

The banknotes on the belt 12 are carried to a primary store (not shown).

FIG. 2 shows a part of the management operation surface of the automatic teller machine shown in FIG. 1, and FIG. 3 shows a block diagram of one embodiment of the present invention.

In Figures 2 and 3, 14 is a setting rotary switch, 15 is a selector, 16 is an OR circuit, and 17 is an AND circuit.
18 is an amplifier, and 19 is a light emitting diode.

The banknote discrimination unit 11 outputs a denomination signal of logic 11 to the output line l-1 if the inserted banknote is distinguished from a 1,000 yen note, and outputs a logic ``11'' denomination signal to the output line 6 if the inserted banknote is discriminated from a 5,000 yen note. It outputs a denomination signal of logic "1", and if it is discriminated from a 10,000 yen note, it outputs a denomination signal of logic "1".

Further, when the banknote validating unit 11 finds some abnormality as a result of validating a certain item, it outputs a determination failure signal of logic "1" to the output signal line 7f.

As mentioned earlier, test banknotes are sometimes used when testing automatic teller machines.

Using a test banknote, the output lines z, , 4, /
, the denomination signals above all become "0", and as a result, all the test banknotes are ejected from the return slot 2, making it impossible to perform a sufficient test.

The low-criteria switch 14 generates a test denomination signal of logic "1" when testing the deposit machine.

When the deposit machine is in the normal mode, the movable contact Sa of the rotary switch 14 is in contact with the fixed contact So.

In the test discrimination mode, the movable contact Sa is the fixed contact S.
1. S2. Touch any of S3.

Assuming that the movable contact Sa is now in contact with the fixed contact S1, a test denomination signal of logic "1" corresponding to the thousand yen denomination signal is generated.

When the deposit machine is tested, a test discrimination command signal is sent from the control section (not shown), and "1" is added to one terminal of the AND 17.

Since the fixed contact S1 is "0", the OR circuit 16 outputs the logic "1", and the output of the AND circuit 17 is therefore "
1”.

The "1" output of the AND circuit 17 is applied to the light emitting diode 19 via the amplifier 18 to light the light emitting diode.

Further, the "1" output of the AND circuit is applied to the selector terminal of the selector 15, and is also sent to the control section as a test discrimination mode signal.

When the selector 15 receives the logic "1" signal from the AND circuit 17, that is, the selector signal, the selector 15 sends the test denomination signal from the rotary switch 14 to the signal line n1 instead of the denomination signal from the bill validator 11. + Output to n2 or n3.

In this case, "1" is output to the signal line n1.

When the control unit receives the test discrimination mode signal, it executes the test program.

When the test discrimination command signal does not exist, that is, when the deposit machine is in the normal mode, no selector signal is generated even if the rotary switch 14 is set to the test discrimination mode, and the acid selector 15 Select the denomination signal from.

As is clear from the above description, the banknote validating device of the present invention treats test banknotes as normal banknotes even if the test recognition result signal generation section is set to the test validating mode by mistake during the normal mode of the banknote validating device. There is nothing to process.
