The present invention relates to a bill receiving device, and more specifically, to a bill receiving device that corrects the folds of the bill so that it can be smoothly taken into the bill.

(B) Prior Art A deposit slot for depositing a large number of deposited banknotes into the deposit slot at once is disclosed in, for example, Japanese Patent Application Laid-open No. 33760/1983.

This conventional deposit slot has a take-in roller deep inside the deposit slot, so the deposit slot is deep, and the deposited banknotes are aligned and inserted by the customer's hand. .

(c) Problems to be solved by the invention In the case of the above-mentioned deposit slot, when the customer inserts the banknotes arranged in a row, the deposit slot is deep, so the customer's hand comes off before the banknotes reach the bottom, making it difficult for the customer to put in the banknotes. The banknotes that have been arranged may become disarrayed on the way, which may cause trouble in taking in the banknotes.

This is especially noticeable when the banknotes are circulated frequently and have folds and wrinkles, and in such cases, there is a problem that jams occur during the transfer of the banknotes.

Therefore, it is conceivable to clamp the inserted banknotes on the left and right sides with clamps, etc. at the upper receiving position, and transfer them to the bottom in this clamped state. Even if the banknotes are held and transferred in the same position, even if the pressure plate for taking in banknotes presses the banknotes at the bottom take-in position, the above-mentioned creases will not be smoothed out and the problem will be a problem in taking in the banknotes. has.

Therefore, the object of this invention is to provide a banknote receiving device that can smoothly take in banknotes without causing any hindrance.

(d) Means to solve the problem This invention uses a U-shaped clamp.

A retaining plate is pivotably mounted to be openable and closable, and biased toward the closing side, and the pair of clamps are arranged with the U-shaped opening sides of the clamps facing the left and right sides of the inserted banknotes, and the upper a lifting mechanism supported on a guide rod so as to be movable between a banknote receiving position and a lower banknote taking position, connected to a fixed piece of the clamp, and raising and lowering the pair of clamps between the banknote receiving position and the banknote taking position; cam protrusions are provided in series from the movable piece of the clamp, and release cams are disposed at each of the banknote receiving position and the banknote taking position to contact the cam protrusions and release the clamp, An opening piece is provided in series on the plate, and an opening operation mechanism is provided that moves the opening piece to the banknote receiving position to open the receiving plate, and the left and right clamps are connected to the banknote accepted by the clamp at the banknote receiving position. a drive mechanism in which wrinkle smoothing and pressing plates are arranged so as to be removable and facing each other at a position in between, and when the clamp moves downward from the banknote receiving position, the wrinkle smoothing and pressing plates are driven to press with a wrinkle smoothing pressure; The present invention is characterized in that it is a banknote accepting device equipped with a.

(E) Function According to the bill receiving device of this invention, when the clamp is located at the bill receiving position, the cam protrusion of the movable piece of the clamp is in contact with the release cam on the bill receiving position side, so that the movable piece does not move. The fixing pieces are separated against the biasing force, and the clamp forms a U-shape, and the bottom of the clamp is closed by the force of the receiving plate, so that it is in a position to accept banknotes.

When the banknotes arranged by the customer are inserted into the banknote receiving position, the left and right sides of the banknotes face the clamps, and the lower edges of the banknotes are received and supported by the receiving plates of the clamps.

When the banknote is allowed to be taken in, the drive mechanism operates to drive the wrinkle smoothing and pressing plate, and the wrinkle smoothing and pressing plate presses the banknote in the clamp with a wrinkle smoothing pressure.

During this pressing, if the received bill has creases, the creases are smoothed out.

When the lifting mechanism is driven in this state and the clamp starts to move downward toward the bill receiving position, the cam protrusion on the movable piece of the clamp separates from the release cam on the bill receiving position side, and the movable piece is moved by the biasing force. The clamp holds the banknote by pressing both sides of the banknote between the fixed pieces.

Therefore, the clamp clamps the wrinkled bill.

As the above-mentioned elevating mechanism is driven, the banknote is transferred to the banknote taking-in position at the bottom while being held in the clamp position, and when the cam protrusion of the movable piece of the clamp comes into contact with the release cam at the banknote taking-in position, the banknote is moved. The piece is released against the biasing force, the bill is unclamped, and when the opening piece of the receiving plate is released by the release operation mechanism against the force, the wrinkled bill is taken in. It is served to

Thereafter, the drive mechanism for the wrinkle smoothing and pressing plate is released and the wrinkle smoothing and pressing plate is returned to its original position.

In addition, to return the clamp to the bill accepting state,
When the release operation mechanism releases the device on the opening piece of the receiving plate, the receiving plate returns to the closed position of the clamp, and when the elevating mechanism returns the clamp to the bill receiving position, the cam protrusion on the movable piece of the clamp engages the release cam. In contact with
The clamp returns to the bill-accepting position.

(f) Effects of the invention As a result of the above, according to this invention, the banknotes arranged by the customer are held in the clamp in a further wrinkled state and transferred from the receiving position of the deposit slot to the internal taking position. Therefore, even with a deep deposit slot structure, the banknotes can be fed to the receiving position in an orderly manner without disturbing the alignment of the banknotes due to creases, and the banknotes can be taken in properly.

Moreover, during the taking-in operation, the wrinkles and folds of the banknotes are maintained, even if the banknotes are deformed due to wrinkles and folds. It can be expanded and incorporated into the bank in the same way as new banknotes, completely eliminating the current jams.

As a result, the banknotes 2 are taken in one by one and transferred to a subsequent stage via the take-in belts 51, 51.

Then, in a twelfth step 72, the CPU 56 drives the second motor 52 until all the banknotes 2 are taken in, and confirms that all the banknotes have been taken in through the detection signal of the fourth switch 32. At the 13th step 73, the machine waits until the last bill is completely taken in, and at the 14th step 74, the second motor 52 is turned on.
is controlled to stop the rotation of the take-in roller 42.

Next, in a fifteenth step 75, the CPU 56 turns off the first solenoid 21 to close the opening of the receiving plate 5.
Then, in the 16th step 76, the third solenoid 48
is turned OFF, the loading press plate 41 is returned to its original non-pressing state, and in the 17th step 77, the press plate 41 waits for the return time to retreat, and in the 18th step 78, the first motor 33 is driven in the reverse direction to clamp it. At step 79, the first motor 33 is driven until the clamp 6 reaches its original upper limit position. If detected, the reverse rotation of the first motor 33 is stopped in a 20th step 80, and the banknote 2 deposit process is completed.

Such processing operations are repeated and the inserted banknotes are taken into the inside as appropriate.
