[Detailed description of the invention] [Summary] This is a residual banknote detection sensor that ensures the detection of folded or fallen banknotes in the pool part of the input section of a building recycling unit, and ensures the prevention of banknotes remaining with a simple configuration. It makes it possible to

[Industrial application field]

The present invention relates to a sensor that detects the presence of banknotes remaining in a pool, and more specifically, to a sensor that expands the detection range three-dimensionally while avoiding complication of the configuration.

In recent years, various financial institutions such as banks have been automating deposits and payments using automatic teller machines and the like. Therefore, it is required to further ensure automatic operation of each part.

FIG. 3 is a front view schematically showing the BRU (Building Recycling Unit).

In FIG. 3, reference numeral 1 denotes an input unit that serves both to input cash deposited by the customer and to withdraw cash for payment.

Reference numeral 2 indicates an input port provided at the upper part of the input section 1, and reference numeral 3 indicates a pool section provided directly below the input port 2.

Regarding the movement of banknotes in BRU, we will first explain the case of deposit operation. When the customer supports the deposit by operating keys and inserts banknotes 4 into the slot 2, the banknotes are directly fed out from the slot without being taken into the pool during the deposit operation of the BRU. The pool section is used when making a deposit when the authenticity cannot be distinguished by the discrimination section, and in this case, unidentifiable banknotes are temporarily taken into the pool section and returned to the customer all at once.
One sheet at a time is continuously transported into the BRU through a transport path 5 configured within the BRU using transport rollers and the like.

The authenticity of the banknotes 4 is discriminated in the discrimination unit 6, and the front and back sides are distinguished and unified in the front and back unit 7. Banknotes that are not suitable for recycling are rejected to the reject box 8, and other banknotes are classified by denomination. Each item is stored in the safe section 9.

In addition, 10 is a power supply unit, 11 is an operation panel, and 12
is the base.

In the case of a payment operation, when a customer instructs payment by operating a key, the required number of banknotes for each denomination is taken out from the safe section 9 after checking the balance within the BRU, and is continuously sent to the pool section 3.

When all the banknotes 4 to be paid are sent into the pool section 3, the banknotes 4 in the pool section 3 are moved at once to the input slot 2 and provided to the customer.

During the BRU deposit operation, banknotes are dispensed directly from the slot without being taken into the pool. The pool section is used when making a deposit when the authenticity cannot be distinguished by the discrimination section, and in this case, unidentifiable banknotes are temporarily taken into the pool section and returned to the customer all at once. In addition, at the time of payment, the banknotes conveyed one by one by the conveyance path 5 are collected in the pool part 3, and then
It is now being sent to

Therefore, the pool section 3 is essential for connecting the input port 2 and the conveyance path 5 within the BRU.

Moreover, the banknotes 4 in the pool section 3 must be handled so that all of them are fed into the conveyance path 5 or all of them are moved to the input port 2.

In particular, if there are residual banknotes in the pool section 3 at the time of payment, there will be a shortage of cash for payment, which will become an obstacle.

Therefore, there is a need for a sensor that can reliably detect residual banknotes in the pool section 3.

[Conventional technology]

Conventionally, a sensor for detecting residual banknotes in the pool part 3 has a detection range within a flat area of a certain height inside the pool part 3, as shown in FIGS. 4 to 6, for example. Ta.

That is, in the conventional detection sensor 20, a light emitting element 22 and a light receiving element 23 are provided at the same height on one side 21 of the pool part 3.

The luminous flux 24 emitted by the light emitting element 22 is transmitted to the pool portion 3
The light emitting element 22 and the light receiving element 2 on the other side 25
A pair of mirrors 26 and 27 provided at the same height positions corresponding to the light beams 28 and 27 form light beams 28 and 29 and are guided to the light receiving element 23.

Therefore, the detection range by this detection sensor 20 is configured in a planar shape by the luminous flux 24 and the luminous flux 29.

Banknotes taken into the pool section 3 from the input slot 2 during the deposit operation, or banknotes collected from the conveyance path into the pool section 3 during the payment operation, are usually stored in the fifth bank.
As shown in the figure, it is in the open and standing position. Even if these banknotes remain in the pool 3 due to a malfunction when they are moved all at once to the slot 2, for example, they will remain open and standing in the same way as usual. , 29.

However, banknotes often become folded in the pool portion 3 due to folding habits formed during use, or due to skewed movement of the banknotes during conveyance through the conveyance path 5 .

As shown in FIG. 6, if a folded bill remains in the pool part 3 in a fallen state, it is impossible to detect it because it is lower than the flat detection range constituted by the detection sensor 20. It is possible.

As a result, folded banknotes remained in the pool section 3, causing a problem.

[Problem that the invention attempts to solve]

With this conventional method, it was not possible to completely detect the remaining banknotes in the pool, which caused problems.

The present invention was created in view of these points, and aims to provide a residual banknote detection sensor that can reliably detect even folded banknotes using a three-dimensional detection range.

[Means for solving problems]

In the residual banknote detection sensor of the present invention, the light emitting element and the light receiving element are provided at three-dimensionally shifted positions.

The light beam emitted from the light emitting element and the light beam reflected by one or more mirrors form a group of light beams in a three-dimensionally shifted state from each other.

[Effect]

In the residual banknote detection sensor of the present invention, the light emitting element and the light receiving element are three-dimensionally displaced, and the luminous flux groups are three-dimensionally displaced from each other, so the banknote detection range is three-dimensional. It consists of a wide range of areas.

Therefore, even if there are folded or fallen bills among the payment bills or deposited bills sent into the pool section of the input section of the building recycling unit, the bills will be removed by any of these groups of light beams. can be detected.

Therefore, problems such as remaining banknotes do not occur.

In addition, it is economically advantageous because there is no need to increase the number of light emitting elements and light receiving elements installed in order to construct such a widened detection range.

〔Example〕

FIG. 1 and FIG. 2 are examples of the present invention,
FIG. 1 is a perspective view showing the mounting state of the detection sensor, and FIG. 2 is a perspective view showing four patterns of detection states by the detection sensor.

The detection sensor 20 of this embodiment is
A light emitting element 22 on one side 21, a light receiving element 23 on the bottom surface 30 of the pool part 3 at a position three-dimensionally shifted from the light emitting element 22, and the other side 25 of the pool part 3.
A mirror 26 is provided at a position laterally shifted with respect to the light emitting element 22, and a mirror 27 inclined diagonally downward is provided at a position away from the light emitting element 22 on the one side surface 21 of the pool portion 3.

Note that 31 is a sensor driver connected to the light receiving element 23, 32 is a control unit, and 33 is a motor and a magnet.

Since the detection sensor 20 of the embodiment is arranged in this way, the light beams 24, 34, and 35 from the light emitting element 22 to the light receiving element 23 are three-dimensionally shifted from each other, and therefore spread three-dimensionally. The ivy detection range is configured.

It is clear that this can be detected when a normal open banknote remains in the pool section 3. Therefore, the detection situation when a folded banknote remains in a fallen position will be described in the following. The explanation will be based on Figure 2.

In pattern 1 of FIG. 2, the remaining banknotes 4 are
Pool section 3 with light emitting elements 22 provided by folding in two vertically
It is in a state where it has fallen down to a position close to one side 21 of the. The detection sensor 20 can detect this banknote at the position of the light beam 35.

Pattern 2 in FIG. 2 shows a case where the position of the folded and fallen remaining banknote 4 is close to the other side surface 25 of the pool part 3, but even in this case it can be detected at the position of the light beam 35.

In both patterns 3 and 4 of FIG. 2, the remaining banknotes are folded in half horizontally, and can be detected by the luminous flux 24 or the luminous flux 34.

In this way, according to the detection sensor 20,
Even if the remaining banknotes fall down or stand in a folded state, the residual banknotes can be detected reliably, and in this respect, troubles can be prevented.

In the detection sensor 20, only one light-emitting element 22 and one light-receiving element 23 are used, so the structure does not become more complicated than in the past.

Light emitting element 22, light receiving element 23, and mirror 2
By arranging the light beams 6 and 27 in this manner, three light beams 24, 34, and 35 are formed within the pool portion 3, and since these light beams are at positions shifted from each other three-dimensionally, three-dimensional This constitutes a detection range that extends to

Therefore, the detection range is substantially expanded without complicating the structure.

[Effect of idea]

As described above, according to the present invention, residual banknotes can be reliably detected using a three-dimensional detection range with a simple configuration, and is extremely useful in practice.
