Automated Teller Machine (ATM) is an automated device that can support basic financial services such as deposit or withdrawal without any bank staff, regardless of location and time in relation to financial services. It is configured so that the user himself or herself can perform financial transactions such as deposit or withdrawal of cash.

These automated financial devices provide various financial services such as deposit or withdrawal of paper media such as banknotes or checks, check balances, and account transfers.To provide such various financial services, the automated financial machines provide deposit and withdrawal departments, card readers, and bankbooks. Various modules such as a organizer are mounted independently, and the modules are electrically connected to the controller and controlled by the controller.

In the deposit and withdrawal section for deposit and withdrawal transactions of such automated financial devices, there is a space for storing bills inside the shutter, and when the shutter is opened, the pocket type is mainly applied to insert or receive bills by putting a hand inside the shutter. Became.

However, in the process of inserting bills into the bill storage space provided inside the shutter or receiving the stacked bills, the shutter is closed even when the user's hand is located inside the shutter. When such a problem occurs, the user may be injured by the power of the motor driving the shutter. In addition, even when the shutter is pressed by the user's hand, the open/close operation is repeatedly performed, resulting in a load shock. As a result, there is a problem in that the life of the motor and gear that performs the opening and closing operation of the shutter is shortened, and frequent breakdowns in the ATM machine occur.

In order to solve the above problems, Japanese Patent No. 4,507,399 discloses an automated financial device to which a present type is applied.

The prior art is equipped with a tray capable of loading bills into the deposit and withdrawal unit, so that bills are input or discharged through the movement of the tray, so that the customer can store bills provided in a conventional pocket type automatic financial machine. You can easily insert or receive bills into automated financial machines without putting your hand in the space, and recently there is a Drive-through ATM that allows customers to use automated financial machines even while in a vehicle. As it becomes more common, the preference of automated financial devices to which the presentation method is applied is increasing so that the deposit and withdrawal of cash or checks can be performed easily through a tray without having to stretch the body and arms out of the vehicle.

However, in this type of present type automatic financial device, a detection sensor that determines the presence or absence of bills on the tray is composed of a pair of light-receiving elements and light-emitting elements in the upper and lower portions of the deposit/withdrawal unit through which bills are inserted or discharged. In this case, when the automatic financial device is installed in a place with relatively strong lighting or outdoors and exposed to strong sunlight, strong external lighting or external light such as sunlight is provided to the reception part structures such as bills or bill loading trays and clamping plates. Is reflected in the light receiving unit, and accordingly, even though the bill is still placed in the tray, the control unit of the automated financial machine determines that there are no bills in the tray, and an error of operating the clamping plate or shutter before the customer collects the bills Will occur.

1 is a perspective view schematically showing the appearance of a reception part of a present-type automatic financial machine deposit and withdrawal unit to which the present invention is applied, and FIG. 2 is a side cross-sectional view showing the structure of the reception part of a present-type automatic financial device deposit and withdrawal part to which the present invention is applied.

In general, an automated financial device is provided with a deposit and withdrawal unit, and the deposit and withdrawal unit receives banknotes from a user when there is a transaction deposit and performs a function of depositing and withdrawing banknotes of the corresponding amount when a transaction withdrawal request is requested from the customer.

The customer service unit 100 of the automatic financial machine deposit/withdrawal unit according to the present invention is configured in a present type in which bills are input or discharged through the front and rear movement of the bill loading tray, as shown in FIGS. 1 and 2 As described above, the tray 200 is provided to form a bill loading space and is movable forward and backward, a clamping plate 300 for preventing separation of bills loaded on the tray 200, and the tray 200. It is configured to include at least one detection sensor 400 consisting of a light-receiving unit 410 and a light-emitting unit 420 disposed in a pair at the top and bottom, respectively.

Accordingly, in the detection sensor 400 according to the present invention, as shown in FIGS. 1 and 2 (a), through the through hole 430 formed in the tray 200, constituting the detection sensor 400 When the light signal emitted from the light-emitting unit 420 is detected by the light-receiving unit 410, it is determined that there are no bills on the tray 200, and as shown in Fig. 2(b), the bill is placed on the top of the tray 200. When the light signal that is loaded and emitted from the light emitting part 420 is blocked by the bill and is not detected by the light receiving part 410, it is determined that the bill is loaded on the tray.

That is, in the present-type automated financial device, when depositing is performed, the tray 200 is protruded forward by opening a shutter (not shown) according to the customer's deposit request, and when the customer loads the bill on the tray, it is detected. In the case of detecting the loaded bills through the sensor 400, lowering the clamping plate 300 to fix the loaded bills, and then moving the tray 200 to the rear to complete the deposit operation of the reception part, and performing withdrawal In this, a shutter (not shown) is opened, and the withdrawal bill to be withdrawn at the request of the customer is seated on the top and the tray 200 in a fixed state by the clamping plate 300 is projected to the front of the deposit and withdrawal unit, and then the customer When bills are collected from this tray, the detection sensor detects that no bills are loaded on the tray, and the withdrawal is completed by moving the empty tray to the rear.

Herein, in FIG. 1 described above, the through hole 430 is formed at a predetermined position of the tray 200, but the present invention is not limited to this structure, and the tray 200 or clamping forming a typical reception part structure In a structure such as the plate 300, a number of through spaces of various shapes may be partially formed, and an optical signal may be transmitted from the light emitting part to the light receiving part through this space.

However, in this process, when the automated financial machine is installed in a place with relatively strong lighting or is installed outdoors and exposed to strong sunlight, the loaded bills or the structure of the reception part are exposed to external light even though the bills are loaded on the tray. There is a problem of judging that the bill is not placed on the tray due to a detection error detected by the light receiving unit due to the reflection.

FIG. 3 is a view for explaining a phenomenon in which external light is reflected on a bill or a reception part structure such as a tray and a clamping plate loaded on a tray and is incident on a light receiving part.

As shown in Fig. 3, when the automated financial device is installed in a place with strong lighting or is installed outdoors and exposed to strong sunlight, in the process of deposit or withdrawal by financial transaction, external light such as strong external lighting or sunlight A detection error occurs by being reflected on the bills stacked on the tray or reflected on a reception part structure such as the bill loading tray 200 or the clamping plate 300 to enter the light receiving part 410 and detect it.

For example, when a customer requests a withdrawal transaction, the automated financial device protrudes the tray 200 loaded with the withdrawal bill in front of the deposit and withdrawal unit in order to perform the withdrawal transaction. In this case, external lighting such as external lighting or sunlight As the bills are reflected on the bills stacked on the tray or reflected on the reception part structure such as the bill loading tray 200 or the clamping plate 300 and incident on the light-receiving part, the detection sensor 400 is emitted from the light emitting part 420. As the light was mistaken for being detected by the light-receiving unit, and it was determined that the bill was collected from the tray 200 even though the bill was still placed on the tray, and the customer operated the shutter (not shown) before the bill was collected, Problems such as the customer being unable to receive bills after withdrawal may occur.

The present invention is to effectively overcome the operation error of the detection sensor as described above.In the present invention, in configuring a detection sensor consisting of a pair of light-receiving parts and light-emitting parts, while adjusting the reception sensitivity of the light-receiving part constituting the detection sensor, By controlling the amount of light of the optical signal emitted through the light emitting unit, the detection error of the receiving unit caused by incident reflected light is suppressed, and the optical signal emitted from the light emitting unit is effectively detected through the receiving unit.

That is, the detection sensor applied to the customer service in the present-type automatic financial device as in the present invention is a light-receiving sensor constituting a light receiving unit using a sensor module for a short distance having an operating distance corresponding to the height (h) of the entrance and exit of the customer service. And a light emitting device of the light emitting unit, and a sensor module for a medium distance having a working distance of 100mm to 120mm is usually used. At this time, in the present invention, by lowering the sensitivity of the light-receiving sensor constituting the light-receiving part than the reference sensitivity, the sensitivity to the reflected light is reduced, effectively preventing the detection error of the light-receiving part due to the incidence of the reflected light reflected from the bill or the reception part structure loaded on the tray. have.

Looking at this in more detail, the sensor sensitivity of the light receiving unit can be adjusted by adjusting a resistance value applied to the sensor, and in an embodiment of the present invention, a sensor having a reference applied resistance of 1KΩ according to the design specification is applied, As a result of testing while changing, it was confirmed that when the applied resistance is 600Ω or less, it is possible to effectively prevent the detection error of the light-receiving unit due to the incident of reflected light.

However, in this case, if the sensing sensitivity of the light-receiving unit is set too low, the detection efficiency of the optical signal emitted from the light-emitting unit is also lowered, and an error may occur in that the optical signal emitted from the light-emitting unit is not properly detected. Preferably, it is preferable to maintain the sensor sensitivity of the light receiving unit in the range of 40% to 60% of the reference sensitivity.

In addition, in the present invention, in order to effectively compensate for the detection efficiency of the light-emitting light signal emitted by the light-emitting unit, which is relatively lower as the sensing sensitivity of the light-receiving unit is lowered, as described above, the light-emitting element constituting the light-emitting unit is The detection accuracy of the detection sensor is further improved by replacing it with a light-emitting element for medium and long distances that provides a high light output of about 120% to 200%, and through this, the detection margin between the light-emitting light signal and the reflected light is effectively increased. Is improving the detection efficiency.

Further, in the present invention, by using a dark dark color such as black, dark blue, or dark gray to configure the reception part structure including a tray or clamping plate that has been applied in a conventional metallic-silver tone, the reception part structure By suppressing the occurrence of reflected light caused by, the detection error of the light receiving unit due to external light reflection such as strong external lighting or intense outdoor sunlight is more effectively prevented.

Here, in the case of applying a dark color to the reception part structure including the tray or clamping plate as described above, and applying an antireflection coating to the structure surface using a matte paint, etc., detection errors can be more effectively prevented. to be.

In addition, in order to prevent detection errors due to reflected light, one solution may be to adjust the diameter of the opening formed on the front surface of the light receiving unit and into which light is incident. As a result of the experiment, the diameter of the opening, which was 6mm, is less than 50%. When reducing to the size of (preferably 2mm to 3mm), it was confirmed that detection errors due to reflected light were reliably blocked, and a more spacious detection margin could be secured.

As described above, in the structure of the reception part of the deposit/withdrawal part of the automated financial device according to the present invention, the reception sensitivity of the light receiving part constituting the detection sensor is set lower than the design specification, and even when the bill is placed on the tray, it is reflected on the bill or the reception part structure. By applying a light emitting device for medium and long distances to the light emitting part, while effectively preventing the detection error of the light-receiving part, which judges that no bills are placed on the tray, low reception of the light-receiving part when bills are not placed on the tray. By supplementing the sensitivity through the relatively high light output of the medium-to-long-distance light emitting device, the presence or absence of bills on the tray can be accurately detected.

Furthermore, by manufacturing the bill loading tray and clamping plate, which constitute the customer service part of the automatic financial automatic machine deposit/withdrawal part, in a dark color such as black, dark blue, or dark gray, the reflection of external light by the structure of the reception part is reduced, It is possible to more effectively prevent the detection error of the light receiving unit.

The present invention described above is not limited by the above-described embodiments and the accompanying drawings, and that various self-substitution, modifications and changes are possible within the scope of the technical spirit of the present invention. It would be obvious to those of ordinary skill.
