By the way, an automated teller machine often employs PINPAD (Personal Identification Number PAD) as a ten-keyboard for inputting a personal identification number used for transactions. In addition, PINPAD is arranged near the customer service opening (banknote deposit / withdrawal opening) photographed by the handheld camera. In particular, in a small automated teller machine, the customer service port and PINPAD are close to each other. Due to this arrangement, the handheld camera takes a picture of PINPAD in addition to the customer service opening, and there is a problem that personal information such as a personal identification number may be leaked as video data. For this reason, automated teller machines need to mask areas of PINPAD that should not be imaged.

As a means of masking, there are a method of masking by hardware in the imaging unit and a method of masking by software in the image processing apparatus. For example, as a method of masking in terms of hardware, the handheld camera (imaging unit) includes, for example, a camera mounting mechanism having an angle of view adjusting mechanism, and the angle of view (imaging area) so that the captured image matches the customer-requested image. Is conceivable to have an adjustable configuration.
However, a small automatic teller machine in which the customer service opening (banknote interface unit) and PINPAD are close to each other requires a finely adjustable mechanism for adjusting the angle of view. Such an angle of view adjusting mechanism is not realistic because it is an expensive mechanism.

An object of the present invention is to provide an automated teller machine capable of setting a non-imaging area around a bill interface unit.

In order to solve the above-mentioned problems, the automated teller machine (100) of the first invention has a bill interface unit (10) in which either one or both of bill insertion and removal are performed, and the bill interface portion (10) is moved upward. An image pickup unit (50) for imaging from an image pickup unit (50), an image pickup limiting unit (30) for limiting the image pickup region of the image pickup unit (50) by providing a non-transmissive region (30b) of light, and an input for accepting input of personal information. The banknote interface unit is provided with an interface unit (for example, PINPAD 20), the imaging limiting unit 30 is an imaging region by the imaging unit (50) , and the input interface unit is restricted so as not to be an imaging region by the imaging unit. It is characterized in that it is limited to (10). The symbols in parentheses are examples.

According to this, since the image pickup limiting unit limits the imaging area to the banknote interface unit, the periphery of the banknote interface unit can be set as the non-imaging area. Here, the entering-force interface unit, which is preferably disposed in the vicinity of the bill interface unit. As a result, the input interface unit can be set as a non-imaging area.

Further, the automatic trading device of the second invention has a bill interface unit in which one or both of insertion and removal of bills are performed, and an input interface that receives input of a password and is arranged in the vicinity of the bill interface unit. An imaging unit having a unit, an imaging unit that images the bill interface unit from above, a light transmitting region having a shape corresponding to the imaging shape of the bill interface unit, and a light non-transmissive region corresponding to the imaging region of the input interface unit. A limiting unit is provided, and the imaging limiting unit is arranged at a position where the imaging unit cannot image the input interface unit.

According to the present invention, the periphery of the bill interface portion can be set as a non-imaging region.

Hereinafter, embodiments of the present invention (hereinafter, referred to as “the present embodiment”) will be described in detail with reference to the drawings. In addition, each figure is only shown schematicly to the extent that the present embodiment can be fully understood. Therefore, the present invention is not limited to the illustrated examples.

(Explanation of configuration)
FIG. 1 is an explanatory diagram illustrating an imaging region of an imaging unit mounted on an automated teller machine according to an embodiment of the present invention. FIG. 1 shows a cross section of an automated teller machine cut at a central portion in the left-right direction.
The automatic teller machine 100 includes a customer service port 10 as a bill interface unit, PINPAD 20 as an input interface unit, a half mirror 30 functioning as an image pickup limiting unit, a hand camera 50 as an image pickup unit, and a main body housing 90. Be prepared. The automated teller machine 100 includes, as the operation unit 25, a card input unit (not shown) and a printing unit for printing slips, in addition to the customer service port 10 and PINPAD 20.

The main body housing 90 is formed with a two-step staircase-shaped operation unit housing 90a and a ceiling portion 90b extending diagonally upward and forward from the rear portion of the operation unit housing 90a. The upper surface of the operation unit housing 90a is inclined so that the operator can easily operate the housing 90a. The customer service port 10 is a banknote deposit / withdrawal port at which either one or both of the banknotes are inserted and taken out, and is provided at the upper part of the lower stage of the operation unit housing 90a.

The PINPAD 20 is provided at an upper portion of the upper stage of the operation unit housing 90a, that is, at a high position behind the customer service opening 10. The PINPAD 20 includes a numeric keypad on which a personal identification number is input, a microcomputer that encrypts the input personal identification number, and a protection detection net that covers the microcomputer board. The protection detection net is for detecting an act of destruction from the outside, and the microcomputer is configured to destroy sensitive information such as a personal identification number and an encryption key when the act of destruction is detected. By arranging the PINPAD 20 in the upper tier, it is difficult for the vandalism to be performed, and the security is higher than when the PINPAD 20 is placed in the lower tier.

The hand camera 50 is arranged on the ceiling 90b. That is, the hand camera 50 is provided above the customer service port 10 and is configured to be able to take an image of the operation unit 25, particularly the customer service port 10, which is the operator's hand. In the hand camera 50, an angle shift (axis runout) at the center of the angle of view occurs due to a mounting angle with respect to the ceiling portion 90b and a position shift of the internal CCD element. Due to this axial runout, the captured image range causes upside and downside of the angle of view. The customer service opening 10 exists in the overlapping range of the upside and downside of the angle of view.

The half mirror 30 is a mirror having a reflectance and a transmittance of 50%, but in the present embodiment, it is used as a so-called magic mirror. The magic mirror can see a reflected image when looking at a dark place from a bright place, and can see a transmitted image when looking at a bright place from a dark place. In the magic mirror, the amount of light reflected from a bright place to a bright place and returned is larger than the amount of light transmitted from a dark place to a bright place, and the amount of light transmitted from a bright place to a dark place is dark. It utilizes the fact that it is more than the amount of light that is reflected back to a dark place.

The half mirror 30 is arranged near the lens of the hand camera 50 so that the hand camera 50 arranged in a dark place can take an image of the customer service opening 10 arranged in a bright place. Further, the operator in a bright place can see the reflected image with the half mirror 30, but cannot see the hand camera 50 arranged in the dark place.

The half mirror 30 is provided with a light transmitting portion 30a and a light non-transmitting portion 30b (FIGS. 3B and 4), and it is assumed that a part of the PINPAD 20 is within the captured image range due to the axial deflection of the handheld camera 50. Also, the light non-transmissive unit 30b has a function as an image pickup limiting unit that limits the imaging of a part of the PINPAD 20.

FIG. 2 is a plan view of an operation unit of an automated teller machine according to an embodiment of the present invention. FIG. 2 is also a view looking into the operation unit (particularly, the customer service opening 10) 25 from above, and the front, back, left, and right are as shown in the figure.
The customer service port 10 is arranged in the main body housing 90, and the PINPAD 20 is a central portion of the customer service port 10 and is arranged close to the rear portion thereof. Since the PINPAD 20 is arranged behind the central portion of the customer service opening 10, the possibility that a third party looks into the PINPAD 20 is reduced. The PINPAD 20 includes a plurality of numeric keypads 20a and a plurality of function keys 20b.

3A and 3B are perspective views of an imaging unit and an imaging limiting unit, FIG. 3A shows an imaging unit, and FIG. 3B shows an imaging limiting unit. The handheld camera 50 includes an imaging unit housing 50a. FIG. 4 is a structural diagram of the image pickup limiting unit.
The half mirror 30 is provided with a light transmitting portion 30a having a reflectance and a transmittance of 50% and a light non-transmitting portion 30b having a transmittance of 0%, and functions as an imaging limiting unit that limits the imaging of the PINPAD 20.

The half mirror 30 that functions as an imaging limiting unit is a plate-like medium in which the central portion is coated with a dielectric multilayer film having a reflectance and a transmittance of 50%, and the outside thereof is a non-transmissive paint having a transmittance of 0%. Is applied. That is, in the half mirror 30, the central portion functions as a light transmitting portion 30a, and the outer side thereof functions as a light non-transmitting portion 30b. Here, the light transmitting portion 30a corresponds to the imaging shape of the customer service port 10, and has a shape similar to that of the customer service port 10 if the customer service port 10 is not inclined with respect to the optical axis.

FIG. 5 is a diagram showing the relationship between the imaging region and the imaging restriction region of the operation unit.
The imaging area of the handheld camera 30 when the half mirror 30 is not provided is the operation unit 25 (FIG. 1), that is, the customer service opening 10, the periphery of the customer service port 10, and a part of the PINPAD 20. A part of the PINPAD 20 is an imaging limiting region that limits the imaging of the handheld camera 30, and corresponds to the light non-transmissive portion 30b. The customer service opening 10 and its surroundings are an imaging region (actual imaging region) of the handheld camera 30 when the half mirror 30 is provided, and correspond to the shape of the light transmitting portion 30a (FIGS. 3 (b) and 4). There is. That is, the shape of the light transmitting portion 30a is set corresponding to the customer service opening 10 and its surroundings. The light non-transmissive portion 30b does not necessarily have a similar shape to the PINPAD 20.

FIG. 6 is an explanatory diagram for explaining the angle of view of the imaging unit.
The handheld camera 50 as an image pickup unit simply includes a CCD element 51 as an image pickup element and a lens 52. In the hand camera 50, the CCD element 51 and the lens 52 are fixed to the image pickup unit housing 50a (FIG. 3 (a)), and the image pickup unit housing 50a is fixed to the main body housing 90 (FIG. 1). To do. The CCD element 51 is a photoelectric conversion element arranged two-dimensionally. Although the lens 52 shows a single focus lens having a focal length f, it may be composed of a plurality of lenses. Further, the lens 52 may be a zoom lens or a fisheye lens.

The handheld camera 50 is in focus at the point at infinity when the distance between the principal point of the lens 52 and the imaging surface of the CCD element 51 is adjusted to be the focal length f. The angle at which the imaging surface of the CCD element 51 is viewed from the center of the lens 52 in a state of focusing on the point at infinity is called an "angle of view". The optical axis is a perpendicular line of the imaging surface of the CCD element 51 and is an axis that coincides with the central axis of the lens 52.

FIG. 7 is an explanatory diagram for explaining the influence of the angle deviation of the imaging unit.
FIG. 7 shows a case where the mounting angles of the CCD element 51 and the lens 52 to the imaging unit housing 50a vary, and the mounting angles of the imaging unit housing 50a to the main body housing 90 vary. .. That is, FIG. 7 shows a case where the optical axes of the CCD element 51 and the lens 52 have an angular deviation (tolerance) from the reference optical axis, and the inclination varies. For example, when the CCD element 51 and the lens 52 rotate slightly clockwise, an upward swing of the angle of view occurs, and when the CCD element 51 and the lens 52 rotate slightly counterclockwise, the downward swing of the angle of view occurs. Occurs. Here, the reference optical axis is the optical axis when there is no tilt variation.

There is a superposed region in which the imaging region at the maximum positive value and the imaging region at the maximum negative value of the mounting angle deviation (deviation) overlap. The superposed region at the maximum value of the deviation of the mounting angle (maximum value of the runout) is a region that can be imaged without depending on the manufacturing variation.

As described with reference to FIG. 7, in the handheld camera 50, the upside and downside of the angle of view occur due to manufacturing variations. Therefore, the captured image may vary in the range from the imaging region (upside down) to the imaging region (downside). In the case of "upside down", the part that should not be reflected as a photographed image (PINPAD20) is not reflected, but in the case of "downside", the part that should not be reflected as a photographed image (PINPAD20) is reflected. ..

The half mirror 30 of the present embodiment is provided with a light non-transmissive portion 30b and a light transmissive portion 30a, and the light non-transmissive portion 30b is used as a mask area for a photographed image (object image). In the half mirror 30, the light transmitting portion 30a corresponds to the shape of the customer service opening 10, and the light non-transmitting portion 30b (mask area) corresponds to the PINPAD 20. Further, in the automatic teller machine 100, the half mirror 30 is arranged at a position (height) where the PINPAD 20 is not reflected by the hand camera 50. As a result, even if the angle of view of the handheld camera 50 varies within the captured image range (downward), the automatic teller machine 100 projects the customer service opening 10 and its surroundings on the captured image so that the PINPAD 20 is not projected. Can be done. That is, the half mirror 30 is directed to customer port 10, and an imaging area of the hand camera 50 its periphery.

(Explanation of effect)
As described above, in the automatic teller machine 100 of the present embodiment, even if the angle of view of the handheld camera 50 varies (upside down, downside), the light non-transmissive portion 30b of the half mirror 30 must not project. The part (PINPAD20) is masked. Therefore, the automatic teller machine 100 does not need to provide a special angle-of-view adjustment mechanism (not shown) in the camera mounting mechanism portion to which the handheld camera 50 is mounted to finely adjust the angle of view. Further, since the light transmitting portion 30a of the half mirror 30 is a magic mirror having a reflectance and a transmittance of 50%, the customer service opening 10 can be imaged from the hand camera 50, while the hand camera 50 and its surroundings can be viewed from the operator. I can't see the wiring.

(Modification example)
The present invention is not limited to the above-described embodiment, and various modifications such as the following are possible.
(1) In the automatic teller machine 100 of the above embodiment, a portion (PINPAD20) that should not be projected, which is generated due to a variation in the angle of view of the hand camera 50, is masked by a light opaque portion 30b of the half mirror 30. By adjusting the boundary shape between the light transmitting portion 30a and the light non-transmitting portion 30b of the half mirror 30, it is possible to project only the operation portion. Further, the half mirror 30 is provided with a plurality of light non-transmissive portions 30b, so that the image capturing portion can be divided into a plurality of portions, and only the necessary portion can be projected.

(2) Although PINPAD20 for inputting a personal identification number is applied to the automatic teller machine 100 of the above embodiment as an input interface unit, it may be used as an input interface for inputting personal information such as a date of birth and a telephone number.

(3) In the automated teller machine 100 of the above embodiment, the half mirror 30 coated with a film having a reflectance and a transmittance of 50% is made to function as a magic mirror having no front and back sides, and an absorbing film is provided on one side of the half mirror. Further coating may be used, and the one with front and back sides may be adopted. For example, a magic mirror coated with a reflective film having a reflectance and a transmittance of 50% and an absorbing film having an absorptance of 50% may be used. At this time, the reflectance of the light incident from the reflecting film side is 50%, but the reflectance of the light incident from the absorbing film side is 50% × 50% × 50% = 12.5%. Further, the total transmittance is 50% × 50% = 25% regardless of the direction of incidence.

(4) Although the hand camera 50 of the above embodiment has been described as having a built-in single focus lens 52, a telecentric optical system can also be used. At this time, a lens having the same size as the customer service opening 10 is required.

(5) Although the automatic teller machine 100 of the above embodiment has been described on the premise of an ATM, it can also be applied to a ticket vending machine, a cash processing machine, and the like.
