Abstract

PROBLEM TO BE SOLVED: To provide a display device and an automatic transaction device.SOLUTION: A display device includes a display unit 12, a light source 11, and a penetration layer 10 that is installed on a display surface side of the display unit and is penetrated by light from the display unit and light from the light source. The light source is installed on an end part of the penetration layer.

Description

  The present invention relates to a display device and an automatic transaction device.

  Recently, automatic transaction apparatuses represented by ATM (Automated Teller Machine) of financial institutions are installed in various places such as banks, station premises, and convenience stores. The customer can perform transactions such as deposit, withdrawal and balance inquiry by performing various operations on the display screen displayed on the automatic transaction apparatus.

  Moreover, the automatic transaction apparatus is designed with a narrow viewing angle of the operation display screen for security. For this reason, even if a third party looks into the display screen from behind or from the left or right of the customer who operates the automatic transaction apparatus (hereinafter referred to as the operator), the display screen viewed from the third party is dark and the display content is visible. It is hard to do.

  As a technique for preventing the peeping of the display screen in this way, Patent Document 1 discloses a peeping prevention body that prevents peeping from the left and right sides and the opposite side of the display screen without impairing the visibility from the operator side. It is disclosed. In such a peep prevention body, two louver layers in which light transmission bands and light shielding bands are alternately arranged are stacked orthogonally, and the light shielding band of one louver layer is inclined with respect to the surface of the other louver layer. .

  However, it may be disadvantageous for the operator to mount the peep prevention body. For example, a display screen on which a peep prevention body is mounted looks somewhat dark for an operator who performs an operation while looking at the display screen, and the display content is difficult to see. Moreover, since the display screen seen from a distant place is dark, it cannot be determined whether or not the automatic transaction apparatus is in a usable state, and the operator must approach the automatic transaction apparatus and check the display screen.

  Patent Document 2 discloses an automatic transaction apparatus provided with means for detecting the presence of an operator according to such a situation. The automatic transaction apparatus sets the luminance state of the display unit to the maximum when there is no operator, and sets the luminance state of the display unit to the minimum when the presence of the operator is detected. When the brightness state is set to the maximum, a person who is away from the automatic transaction apparatus can see that the display screen emits light, so that the automatic transaction apparatus can be used even from a remote place. This is disclosed in Patent Document 2.

JP 2007-212507 A JP 2006-164091 A

  However, the above techniques have the following problems.

  In the said automatic transaction apparatus, the brightness | luminance state of a display part is set to the maximum so that the use condition of an apparatus can be confirmed from a distance. However, since light from the display unit is blocked by a peep prevention body (hereinafter also referred to as a light shielding filter), it is actually darker than the maximum luminance of the display unit, and the display screen is difficult to see. Therefore, it is necessary to mount a display device capable of emitting light with a higher brightness than that required for operation. In an environment where the ambient illuminance is high, a display device with higher brightness is required.

  As described above, it is required to block the light of the display unit with the light blocking filter to prevent the peeping, but on the other hand, it is required to see that the display unit can be used from a distance. In an automatic transaction apparatus, even if a high-luminance display unit is mounted, light is blocked by the light blocking filter.

  In addition, when the ambient illuminance is lower than the light emitted from the display unit and leaking from the light shielding filter, the light from the display unit is not offset by the ambient light. For this reason, when ambient illuminance is low, the display content of a display part tends to be easy to see.

  Therefore, the present invention has been made in view of the above problems, and an object of the present invention is to provide a new and improved display device capable of improving the visibility of light emission from the transmission layer and It is to provide an automatic transaction apparatus.

  In order to solve the above-described problems, according to an aspect of the present invention, a display unit, a light source, and a display surface side of the display unit are provided and transmit light from the display unit and light from the light source. A display device, wherein the light source is provided at an end of the transmission layer.

  The light source may be provided in a range overlapping the transmissive layer in the thickness direction of the transmissive layer.

  The light source may irradiate the transmissive layer with light from a substantially horizontal direction of the transmissive layer.

  The transmissive layer may be provided with irregularities on at least one of the front surface and the back surface of the transmissive layer.

  The uneven region provided in the transmission layer may be a region in which a horizontal region and an inclined region are mixed.

  The unevenness may be at least one of a cone, a polygonal pyramid, a polyhedron, and a curved body.

  You may represent at least any one of a character and a figure by at least any one of arrangement | positioning and the magnitude | size of the said unevenness | corrugation.

  The transmission layer may be composed of multiple layers having different refractive indexes.

  The multilayer may be laminated in a direction perpendicular to the display unit.

  A reflective layer that reflects light emitted from the transmissive layer to the display unit side may be provided between the display unit and the transmissive layer.

  The reflective layer may be a transflective sheet.

  The reflective layer may be a light shielding filter.

  The display device may further include illuminance detection means and first luminance adjustment means for adjusting the luminance of the light source according to the illuminance detected by the illuminance detection means.

  The display device accepts an instruction to adjust the viewing angle of the display unit, and adjusts the luminance of at least one of the display unit and the light source according to the instruction received by the accepting unit And a second luminance adjusting means characterized by:

  Moreover, in order to solve the said subject, according to another viewpoint of this invention, it is provided in the display surface side of the display part, the light source, and the said display part, The light from the said display part and the light from the said light source An automatic transaction apparatus, wherein the light source is provided at an end of the transmissive layer.

  As described above, according to the present invention, the visibility of light emission from the transmission layer can be improved more efficiently.

  Further, since the light from the display unit in the oblique direction is canceled by the light from the light source, the light from the display unit in the oblique direction can be canceled even in an environment where the ambient illuminance is low.

  Exemplary embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In addition, in this specification and drawing, about the component which has the substantially same function structure, duplication description is abbreviate | omitted by attaching | subjecting the same code | symbol.

  In this specification, a display device widely refers to a device having a display portion. In the following embodiments, an automatic transaction apparatus will be described as an example. For example, an information processing apparatus such as a mobile phone, a personal computer, or a PDA (Personal Digital Assistants) is also included in the display apparatus. The display device also includes a unit around the display unit incorporated as a part in the automatic transaction apparatus or the information processing apparatus.

<1. Configuration of automatic transaction system>
First, with reference to FIG. 1, the structure of the automatic transaction system by embodiment of this invention is demonstrated.

  FIG. 1 is a diagram showing a configuration of an automatic transaction system according to an embodiment of the present invention. As shown in FIG. 1, the automatic transaction system according to the embodiment of the present invention includes automatic transaction apparatuses 1A, 1B,... 1N, a communication line 2, and a host computer 3.

  The automatic transaction apparatus 1A is installed in various places such as a bank or a station, and executes a transaction desired by a customer. Specifically, the operation display unit 4A provided in the automatic transaction apparatus 1A has both a function of displaying a display screen for guiding a customer operation and a function of receiving an operation input. For example, the operation display unit 4A may include a touch panel that detects an input to the screen and receives an input as a function of receiving an operation input.

  Further, the automatic transaction apparatus 1A may include a coin deposit / withdrawal port 5A, a bill deposit / withdrawal port 6A, a passbook insertion / return port 7A, and a card insertion / return port 8A. The coin deposit / withdrawal port 5A is an opening through which coins are inserted or discharged. The bill deposit / withdrawal port 6A is an opening through which bills are inserted or ejected. The coin deposit / withdrawal port 5A and the bill insertion / return port 6A are provided with shutters that are operated by a drive unit (not shown). The passbook insertion / return port 7A is a portion into which a passbook used for transactions is inserted or discharged. The card insertion / return port 8A is a portion into which a card used for the transaction is inserted or discharged.

  The passbook inserted from the passbook insertion / return port 7A is subjected to a printing process of withdrawal / payment record and reading of stored information in a magnetic stripe provided on the cover of the passbook. Customer information is read from the card inserted from the card insertion / return port 8A.

  Automatic transaction apparatuses 1A to 1N have substantially the same functional configuration. Hereinafter, since it is not necessary to distinguish between these, it is simply referred to as an automatic transaction apparatus 1.

  The automatic transaction apparatus 1 is connected to a host computer 3 via a communication line 2. The automatic transaction apparatus 1 executes the transaction selected by the customer on the display screen by transmitting / receiving necessary information to / from the host computer 3.

  For example, the automatic transaction apparatus 1 requests the host computer 3 to verify the password entered by the customer, receives customer deposit information from the host computer 3, and receives the deposit amount or withdrawal amount by the customer. Or send to 3.

  The host computer 3 manages customer information. Customer information includes account number, personal identification number, name, address, age, date of birth, telephone number, occupation, family structure, annual income, deposit information, and action history information.

  Here, the deposit information is information related to the customer's deposit, and may include, for example, information related to the type and balance of the customer's ordinary deposit, fixed deposit, foreign currency deposit, securities, investment trust, insurance product, and the like.

  The host computer 3 controls transactions requested from each automatic transaction apparatus via the communication line 2. Furthermore, the host computer 3 can also control the usage state of each automatic transaction apparatus via the communication line 2. Control of the usage state of each automatic transaction apparatus will be described in the sixth embodiment.

  In the automatic transaction apparatus 1 described above, if a light shielding filter is simply provided in the operation display unit 4 to prevent peeping, the problem described in the following comparative example occurs.

[Comparative Example 1]
With reference to FIGS. 2-4, the automatic transaction apparatus 100 provided with the operation display part 101 which concerns on a comparative example is demonstrated.

  FIG. 2 is a cross-sectional view of an automatic transaction apparatus 100 according to a comparative example. Usually, the user stands in front of the automatic transaction apparatus 100 and operates the operation display unit 101 as viewed from the viewpoint A. On the other hand, when viewing the operation display unit 101 from a place away from the automatic transaction apparatus 100, the viewpoint of the user is the viewpoint B.

  FIG. 3 is a cross-sectional view of the operation display unit 101 according to the comparative example. As shown in FIG. 3, the operation display unit 101 is configured by laminating a display unit 104, a light shielding filter 103, and a protection plate 102. As indicated by solid arrows in FIG. 3, the light irradiated from the display unit 104 to the front (viewpoint A) is not affected by the light shielding filter, passes through the light shielding filter, and reaches the viewpoint A. Thus, when the user views the operation display unit 101 from the viewpoint A, the display content of the operation display unit 101 can be visually recognized as shown in FIG. 4A.

  On the other hand, as indicated by an arrow that changes from a solid line to a broken line in FIG. 3, light emitted from the display unit 104 in an oblique direction (viewpoint B) is affected by the light shielding filter and is shielded by the light shielding filter. Thereby, when the user views the operation display unit 101 from the viewpoint B, the display content of the operation display unit 101 cannot be visually recognized as shown in FIG. 4B.

  The operation display unit 101 according to the comparative example described above is effective from the viewpoint of peeping prevention. However, on the other hand, a user who views the operation display unit 101 from a location away from the automatic transaction apparatus 100 thinks that the automatic transaction apparatus 100 is not operating because the operation display unit 101 is dark, and approaches the automatic transaction apparatus 100. The problem that hesitates.

  Then, it came to create embodiment of this invention from the above circumstances. According to the embodiment of the present invention, when a user who is away from the automatic transaction apparatus looks at the operation display section provided in the automatic transaction apparatus, the operation display section appears to emit light. In particular, since the light emitted from the light source provided so that the operation display unit can be seen to emit light is not blocked by the peep prevention body represented by the light shielding filter, the operation display unit can emit light more efficiently. I can do it.

  In addition, according to the embodiment of the present invention, it is difficult for the user who is away from the automatic transaction apparatus to see the display contents only by the operation display unit appearing to emit light. Therefore, a third party who looks into the operation display unit from behind the user who operates the automatic transaction apparatus or from a left or right side only sees the operation display unit to emit light, and the display content is difficult to see. Thus, according to the embodiment of the present invention, a peep prevention effect is also achieved. Hereinafter, first to eighth embodiments of the present invention that exhibit such effects will be described in detail.

<2. First Embodiment>
[Configuration of operation display unit 4]
The configuration of the operation display unit 4 according to the present embodiment will be described with reference to FIG. 5A. FIG. 5A is a cross-sectional view of the operation display unit 4 included in the automatic transaction apparatus 1 according to the present embodiment. As illustrated in FIG. 5A, the operation display unit 4 includes a transmissive layer 10, a light source 11, and a display unit 12. In FIG. 5A, each configuration is shown with a predetermined interval, but this is merely an expression for convenience to clarify the main configuration. Hereinafter, the same applies to the same drawings for explaining the configuration of the operation display unit 4.

  As illustrated in FIG. 5A, the transmissive layer 10 is stacked on the display screen side of the display unit 12 (the upper surface side of the display unit 12). The transmissive layer 10 only needs to propagate light like a light guide plate. The transmissive layer 10 may also serve as a touch panel that detects contact and designates a position on the display screen, or a protective plate that protects the display unit 12.

  Next, the light source 11 will be described. The light source 11 is provided at the end of the transmissive layer 10. For example, as illustrated in FIGS. 5A and 5B, the light source 11 may be provided in a range (thickness width h) overlapping the transmissive layer 10 in the thickness direction of the transmissive layer 10. In FIG. 5B, the size of the light source 11 overlaps with the thickness width h, but the arrangement of the light source 11 is not limited to this. For example, an arrangement in which a part of the light source 11 overlaps the thickness width h may be used.

  Thereby, the light source 11 can irradiate light to the side surface of the transmissive layer 10 from the substantially horizontal direction of the transmissive layer 10. Thus, the light source 11 provided at the end of the transmissive layer 10 and irradiating the side surface of the transmissive layer 10 is also referred to as an edge light.

  Specifically, the light source 11 may be formed of a light emitting component such as a fluorescent tube or an LED (Light Emitting Diode). Further, the light source 11 shown in FIGS. 5A and 5B has a reflective cover that is opened only on the transmissive layer 10 side. Thereby, the light irradiated from the light source 11 to the side other than the transmission layer 10 is reflected by the reflection cover and is irradiated to the transmission layer 10 side. The light source 11 is not limited to one having a reflective cover.

  The display unit 12 displays a transaction operation screen required for a transaction operation that can be performed by the automatic transaction apparatus 1. The transaction operation screen is a menu screen that presents a transaction menu that can be performed by the automatic transaction apparatus 1 such as “withdrawal”, “deposit”, “passbook entry”, “balance inquiry”, “transfer”, etc. In order to perform the transaction, there are a guidance screen for prompting insertion of a card and a passbook, and an input screen for inputting transaction information. The display unit 12 may be, for example, an LCD (Liquid Crystal Display).

  The arrangement position of the light source 11 is not limited to FIGS. 5A and 5B. For example, the arrangement shown in FIG. 6 can be considered as the arrangement of the light source 11 provided at the end of the transmissive layer 10. As shown in FIG. 6, the light source 31 may be provided at the inner end of the transmission layer 30. The light source 31 provided in this way can also irradiate light from a substantially horizontal direction of the transmission layer 30.

[Operation of the operation display unit 4]
Next, the relationship between the angle of the light emitted from the surface 15 of the transmission layer 10 and the luminance will be described with reference to FIG. FIG. 7 is an external perspective view of the operation display unit 4 according to the present embodiment.

  First, light emitted from the display unit 12 provided substantially parallel to the transmissive layer 10 and emitted from the surface 15 of the transmissive layer 10 has high luminance in the front direction and low luminance in the oblique direction. That is, the brightness of the light from the display unit 12 decreases as the angle θ from the normal line shown in FIG. 7 increases, and increases as the angle θ from the normal line decreases.

  On the other hand, the light emitted from the light source 11 provided at the end of the transmissive layer 10 and emitted from the surface 15 of the transmissive layer 10 has higher luminance as the angle θ from the normal line is larger, and the angle θ from the normal line is smaller. The lower the brightness.

  Therefore, in a place where the angle θ from the normal line is small, the light emitted from the display unit 12 has higher luminance than the light emitted from the light source 11. That is, in a place where the angle θ from the normal line is small, the light emitted from the display unit 12 is mainly recognized. Therefore, since the user mainly recognizes the light emitted from the display unit 12 from a place where the angle θ from the normal line is small (front direction), the display content of the display unit 12 can be seen.

  On the other hand, in a place where the angle θ from the normal line is large, the light emitted from the display unit 12 is lower in luminance than the light emitted from the light source 11. That is, in a place where the angle θ from the normal is large, the light emitted from the light source 11 is mainly recognized. Therefore, from the place where the angle θ from the normal is large (in the oblique direction), the user mainly recognizes the light emitted from the light source 11, so the surface 15 appears to emit light, and the display content of the display unit 12 is It's hard to see.

  Next, how the operation display unit 4 is seen from a place where the angle θ from the normal line is large / small will be described with reference to FIGS. 8 and 9.

  FIG. 8 is a cross-sectional view of the automatic transaction apparatus 1 according to the embodiment of the present invention. As a case where the angle θ from the front becomes small, it is assumed that the user stands in front of the automatic transaction apparatus 1 and looks at the operation display unit 4 from the viewpoint A. As a case where the angle θ from the front is increased, it is assumed that the user views the operation display unit 4 from a point of view B where the user is away from the automatic transaction apparatus 1.

  The operation display unit 4 viewed from the viewpoint A and the viewpoint B shown in FIG. 8 is shown in FIGS. 9A and 9B, respectively. When viewed from the viewpoint A, as shown in FIG. 9A, the user can recognize the display contents.

  On the other hand, when viewed from the viewpoint B, as shown in FIG. As described above, the viewpoint B is a viewpoint that assumes a case where the user looks from a place away from the automatic transaction apparatus 1. That is, since the operation display unit 4 appears to emit light when viewed from a user away from the automatic transaction apparatus 1, the user is operating the automatic transaction apparatus 1 (it can also be said that it is in a standby state and usable). I understand that there is.

  Here, the operation display unit 4 viewed from a place away from the automatic transaction apparatus 1 is in a light-emitting state as shown in FIG. 9B, and it is difficult to visually recognize the display contents. Therefore, even if a third party looks into the operation display unit 4 from behind or from the left or right of the user who operates the automatic transaction apparatus 1 (in this case, the third party's viewpoint is at the position shown in the viewpoint B), It is difficult for the three parties to see the displayed contents. Thus, the operation display part 4 which concerns on this embodiment also has a peep prevention effect.

  In the operation display unit 4 according to the present embodiment, the luminance of light from the display unit 12 and the luminance of light from the transmissive layer 10 change depending on the angle from the normal line. Therefore, unlike the above-described automatic transaction apparatus of Patent Document 2, it is not necessary to adjust the luminance of the display unit 12 depending on the presence or absence of a user. In addition, since the light from the light source 11 that exhibits the peep prevention effect is not blocked by the peep prevention body, the operation display unit 4 can emit light more efficiently.

<3. Second Embodiment>
Next, the operation display unit 4 according to the second embodiment of the present invention will be described. In the present embodiment, irregularities are provided on at least one of the front surface (also referred to as the upper surface) or the rear surface (also referred to as the lower surface) of the transmission layer 10 constituting the operation display unit 4 according to the first embodiment. The uneven region provided in the transmission layer is a region in which, for example, a horizontal region and an inclined region are mixed. Hereinafter, this embodiment will be specifically illustrated with reference to FIGS. 10 to 14.

[First irregularity example]
FIG. 10 is a cross-sectional view for explaining the transmission layer 110 provided with unevenness according to the present embodiment. As shown in FIG. 10, irregularities are provided on the surface of the transmission layer 110.

  Further, in FIG. 10, an example of an optical path incident from the light source 11 is indicated by a broken line, and an example of an optical path incident from the display unit 12 is indicated by a solid line. Although it has been described above that the light source 11 irradiates light to the transmissive layer 10 from a substantially horizontal direction of the transmissive layer 10, the angle at which the light emitted from the light source 11 enters the transmissive layer 10 is specifically shown in FIG. Needless to say, it is various as illustrated in FIG.

  The unevenness provided in the transmission layer 110 is formed by mixing the inclined region 160 and the horizontal region 170. Light irradiated from the light source 11 and reflected and propagated through the transmissive layer 110 has an incident angle deepened mainly in the inclined region 160 provided on the surface of the transmissive layer 110 and is emitted from the inclined region 160.

  Light emitted from the display unit 12 and passing through the transmissive layer 110 has a large incident angle mainly in the horizontal region 170 provided on the surface of the transmissive layer 110 and is emitted from the horizontal region 170.

  Thus, by providing the inclined region 160 that mainly emits light from the light source 11, more light from the light source 11 is emitted from the entire operation display unit 4. Therefore, it is possible to further increase the luminance in the oblique direction where the angle θ from the front is large. By increasing the luminance in the oblique direction, for example, a user who has seen the automatic transaction apparatus 1 from a greater distance can recognize the light emission of the operation display unit 4.

  Next, the shape pattern of the transmissive layer 110 shown in FIG. 10 is shown in FIGS. 11A and 11B, respectively.

  The transmissive layer 111 shown in FIG. 11A has a shape pattern in which two inclined surfaces 161 and a horizontal surface 171 are repeated. In such a shape pattern, light from the light source 11 is mainly emitted from the inclined surface 161. Since the light from the light source 11 has higher luminance in the oblique direction, the operation display unit 4 appears to emit light from the direction facing the inclined surface 161 (the direction indicated by the arrow in FIG. 11A).

  Another shape pattern of the transmissive layer 110 is shown in FIG. 11B. The transmissive layer 112 shown in FIG. 11B has a shape pattern in which an infinite number of cones 162 (inclined regions) are provided in the horizontal region 172. The arrangement and size of the cone 162 are not limited to the example illustrated in FIG. 11B.

  In the case of the pattern as shown in FIG. 11B, the brightness of the light from the light source 11 increases in any direction. Therefore, as shown by the eight arrows in FIG. 4 appears to emit light.

  Next, the inclination angle (θ2) of the inclined region will be described with reference to FIG. 12 showing the optical path of the light from the light source 11 incident on the transmission layer 113 which is a modification of the transmission layer 110 shown in FIG.

  As shown in FIG. 12, the light emitted from the light source 11 is reflected by the lower surface of the transmissive layer 113 and is emitted from an inclined region provided on the upper surface of the transmissive layer 113. In this case, the relationship between the incident angle θ4 to the lower surface, the inclined angle θ2 of the inclined region, and the incident angle θ1 to the inclined region is θ4 = θ1 + θ2. That is, θ1 <θ4. The incident angle θ1 to the inclined region is smaller than the reflection angle θ4, and it can be said that θ1 is deeper. θ1 is an angle at which the reflected light is emitted from the inclined region.

  Since there is a relationship of θ4 = θ1 + θ2, the magnitude of θ1 is relatively adjusted by adjusting the inclination angle θ2 of the inclined region. For example, by increasing the inclination angle θ2 of the inclined region, the incident angle θ1 to the inclined region can be relatively reduced, that is, deepened, and light from the light source 11 can be emitted from the inclined region.

  As described above, some specific shapes of the first uneven example are shown, but the uneven shape according to the present embodiment is not limited to this. For example, a polygonal pyramid, a polyhedron, or a curved surface may be used. As an example, FIG. 13A shows a transmission layer 114 having irregularities in the shape of a polyhedron (consisting of a horizontal region 174 and an inclined region 164). As an example, FIG. 13B shows a transmissive layer 115 having irregularities in the shape of a curved body (consisting of a horizontal region 175 and an inclined region 165).

  Moreover, the uneven | corrugated area | region provided in a permeation | transmission layer may be an area | region where such various shapes were mixed, for example, may be a diffusion plate like ground glass.

[Second uneven example]
Next, the optical path of the light from the light source 11 in the transmissive layer 116 having the unevenness on the back surface will be described with reference to FIGS. 14A and 14B.

  FIG. 14A is a cross-sectional view illustrating an example of an optical path of light from the light source 11 in the transmissive layer 116 having an uneven surface on the back surface. As shown in FIG. 14A, the light reflected by the unevenness provided in the transmissive layer 116 is emitted from the surface of the transmissive layer 116.

  14B is a cross-sectional view for explaining the inclination angle (θ2) of the unevenness of the transmission layer 116 shown in FIG. 14A. As shown in FIG. 14B, the light emitted from the light source 11 and reflected by the surface of the transmissive layer 10 b is reflected by the inclined region provided on the back surface of the transmissive layer 116 and is emitted from the surface of the transmissive layer 116. In this case, the relationship between the incident angle θ1 to the back surface, the inclined angle θ2 of the inclined region, and the incident angle θ3 to the front surface when emitted from the front surface is θ3 = θ1−θ2. That is, θ3 <θ1. The incident angle θ3 to the surface is smaller than the reflection angle θ1, and it can be said that θ3 is deeper. θ3 is an angle at which the reflected light is emitted from the surface.

  Since there is a relationship of θ3 = θ1−θ2, the magnitude of θ1 is relatively adjusted by adjusting the inclination angle θ2 of the inclined region. For example, by increasing the inclination angle θ2 of the inclined area, the incident angle θ3 to the inclined area can be relatively reduced, that is, deepened, and the light from the light source 11 can be emitted from the inclined area.

<4. Third Embodiment>
Next, the operation display unit 4 according to the third embodiment of the present invention will be described. In the present embodiment, the transmission layer constituting the operation display unit 4 is composed of multiple layers having different refractive indexes.

  According to this embodiment, more light from the light source 11 can be emitted.

<5. Fourth Embodiment>
Next, an operation display unit 4 according to the fourth embodiment of the present invention will be described. In the present embodiment, a reflective portion is provided between the transmissive layer 10 and the display portion 12. By providing the reflective portion, the light emitted from the transmissive layer 10 toward the display portion 12 is reflected and emitted from the surface of the transmissive layer 10. Thereby, more light from the light source 11 can be emitted.

  The reflective layer according to the present embodiment may be, for example, a semi-transmissive sheet 13. FIG. 16 shows a cross-sectional view of an operation display unit including a transflective sheet 13 as an example of a reflective layer according to the present embodiment. The transmissivity of the semi-transmissive sheet 13 may be lower than the transmissivity. Although the light from the display part 13 is interrupted somewhat by providing the translucent sheet | seat 13, the peeping prevention effect can be exhibited.

  The optical path of light from the light source 11 is indicated by a broken line in the figure. As shown in FIG. 16, the light emitted from the light source 11 and emitted to the display unit 12 side of the transmissive layer 10 is reflected by the semi-transmissive sheet 13, passes through the transmissive layer 10 again, and is emitted from the surface. Thereby, more light from the light source 11 can be emitted.

  Further, as another example of the reflective layer, for example, the light shielding filter 14 may be used. FIG. 17 is a cross-sectional view of an operation display unit including a light shielding filter 14 as an example of a reflective layer according to the present embodiment. Although the light from the display unit 13 is somewhat blocked by providing the light blocking filter 14, a peep prevention effect can be exhibited.

  The optical path of light from the light source 11 is indicated by a broken line in the figure. As shown in FIG. 17, the light emitted from the light source 11 and emitted to the display unit 12 side of the transmissive layer 10 is reflected by the light shielding filter 14, passes through the transmissive layer 10 again, and is emitted from the surface. Thereby, more light from the light source 11 can be emitted.

  In any of the above reflective layers, the operation display unit 4 can emit light efficiently without blocking the light emitted from the light source 11.

  The operation display unit 4 according to the embodiment of the present invention has been described above using the second to fourth embodiments. However, the operation display unit 4 according to the embodiment of the present invention includes the second embodiment. It is good also as a structure which combined the structure of 4th Embodiment from the form.

<6. Fifth Embodiment>
Next, an operation display unit 4 according to the fifth embodiment of the present invention will be described. When the operation display unit 4 according to each of the above embodiments is viewed from a location where the user is away from the user, only the light appears to be emitted, and the display content is difficult to see. In this case, it is conceivable that the user recognizes that the automatic transaction apparatus 1 is in an abnormal state and the display content is not shown. Therefore, in the present embodiment, a display different from the display content is made visible to the user who is away from the operation display unit 4. Thereby, a user can be made to recognize that the automatic transaction apparatus 1 is a normal state.

  Specifically, unevenness is provided on the surface of the transmissive layer 10 constituting the operation display unit 4 according to each of the above embodiments to express characters and drawings. As an example, by providing unevenness in a region other than a character, for example, a triangular pyramid 16B shown in FIG. 11B, a region without the triangular pyramid 16B (character region) becomes dark and is recognized as a black character. FIG. 18 is a diagram for explaining a black character according to the present embodiment. When the operation display unit 4 provided in the automatic transaction apparatus 1 is viewed from a location away from the automatic transaction apparatus 1, the surface of the transmission layer 10 appears to emit light, but the brightness of the emitted light is low in the region without unevenness. Since it looks dark, it is possible to recognize the characters “I welcome you” as shown in FIG.

  Also, as an example, by providing irregularities in the character area and not providing irregularities in the area other than the characters, the character area looks bright, contrary to the example shown in FIG. It is also possible.

  In the above description, an example is described in which characters are expressed with or without unevenness. However, it is also possible to express characters by providing unevenness on the entire surface of the transmissive layer 10. Specifically, by adjusting the size of the unevenness, the arrangement interval of unevenness (dense area, scattered area), and the tilt angle, a relatively bright area and a dark area may be provided to express characters.

<7. Sixth Embodiment>
Next, an automatic transaction apparatus 1a according to a sixth embodiment of the present invention will be described. In each of the above embodiments, the user who has viewed the operation display unit 4 from a remote location recognizes the light emission of the operation display unit 4 (in the case of the fifth embodiment, by further recognizing characters and diagrams). ), It can be seen that the automatic transaction apparatus 1 is in operation. Here, the state of the automatic transaction apparatus 1 is various during preparation, such as suspension of handling, handling possible (usable, also referred to as transactable), and the like. Therefore, even if at least it can be recognized that it is in a normal operation and is in a standby state, it may be misunderstood that it can be used even during preparation or when handling is stopped.

  Therefore, in the present embodiment, the light source 11 is controlled according to the apparatus state of the automatic transaction apparatus 1. Hereinafter, the present embodiment will be described with reference to FIG.

  FIG. 19 is a block diagram showing the configuration of the automatic transaction apparatus 1a according to the present embodiment. As shown in FIG. 19, the automatic transaction apparatus 1 a includes an apparatus state determination unit 20, a control unit 21, and a light source 11. The device state determination unit 20 determines whether the state of the device is an unusable state such as a handling stop during preparation or a usable state. In addition to being controlled by the device itself, the state of the device may be controlled from the host computer 3 via the communication line 2 as shown in FIG. The control unit 21 controls light irradiation by the light source 11 according to the determination result of the device state determination unit 20, that is, the device state. Specific contents of control by the control unit 21 will be described below.

  For example, the control unit 21 performs control to turn off the light source 11 when the automatic transaction apparatus is in an unusable state and turn on the light source 11 when the automatic transaction apparatus is in an available state. If the light source 11 is turned off in the unusable state, the light from the light source 11 that has become a hindrance when the operation display unit 4 is viewed from a remote location disappears, so even from a remote location (even from an oblique direction). ) The displayed content is visible. If the display unit 12 indicates that the operation display unit 4 cannot be used, such as “Preparing” or “Cancel handling”, the user who viewed the operation display unit 4 from a remote location Is unusable.

  Moreover, the control part 2 can also control the color of the light irradiated from the light source 11 according to the state of an automatic transaction apparatus. For example, when the light source 11 includes a plurality of light sources each including a phosphor film that emits light of red, green, and blue, the control unit 2 controls the light emitted from each light source, thereby controlling the operation display unit. 4 emission color is controlled.

<8. Seventh Embodiment>
Next, an automatic transaction apparatus 1b according to a seventh embodiment of the present invention will be described. First, it will be described using a comparative example that the appearance of the operation display unit 4 is affected by ambient illuminance.

[Comparative Example 2]
FIG. 20A is a cross-sectional view of the operation display unit 101 according to the comparative example. As indicated by a broken line in FIG. 20A, the light from the display unit 104 leaks somewhat from the light shielding filter 103. At this time, ambient light also reflects the protection plate 102 and reaches the viewpoint C. Here, the light leaking from the light shielding filter 103 that reaches the viewpoint C is canceled if the reflected ambient light is higher. Therefore, when the ambient illuminance is high, the display content of the display unit 104 cannot be seen from the viewpoint C, and the operation display unit 101 seen from the viewpoint C is dark as shown in FIG. 20C.

  On the other hand, when the ambient illuminance is low, the display content of the display unit 104 is easy to see. Hereinafter, this point will be described with reference to FIG. 20B. FIG. 20B is a cross-sectional view of the operation display unit 101 according to the comparative example. When the ambient light that reflects the protective plate 102 and reaches the viewpoint C has lower brightness than the light that is emitted from the display unit 104 and leaks from the light shielding filter, the light does not cancel. Therefore, the operation display unit 101 seen from the viewpoint C shown in FIG. 20B shows the display content transparently as shown in FIG. 20D.

  As described above, the operation display unit 101 according to the comparative example has a problem that the display content is easy to see particularly when the ambient illuminance is low.

  In the second to fourth embodiments, more light from the light source 11 is emitted from the surface 15 of the transmission layer 10 in an oblique direction. Therefore, the light from the display unit 12 in the oblique direction is offset by the light from the light source 11. For this reason, it is possible to cancel light from the display unit 12 in an oblique direction even in an environment where the ambient illuminance is low.

  As described above, also in each of the above embodiments, it is possible to cancel light from the display unit 12 in an oblique direction in an environment where the ambient illuminance is low, but in the present embodiment described below, according to the ambient illuminance. By adjusting the brightness of the light source 11, the display unit 12 can be made more difficult to see.

  The structure of the automatic transaction apparatus 1b which concerns on this embodiment is demonstrated with reference to the block diagram shown in FIG. As shown in FIG. 21, the automatic transaction apparatus 1 b includes an illuminance detection unit 22, a luminance adjustment unit 23, and a light source 11. The illuminance detection unit 22 detects the illuminance near the operation display unit.

  The luminance adjustment unit 23 adjusts the luminance of light emitted from the light source 11 according to the detection result of the illuminance detection unit 22. For example, when the illuminance near the operation display unit 4 is low, the luminance of the light emitted from the light source 11 is increased. Further, the automatic transaction apparatus 1b stores in advance a correspondence table in which the brightness of the light source 11 with respect to the value of the ambient illuminance is associated with the brightness of the light source 11 in an oblique direction. You may keep it. The brightness adjusting unit 25 may adjust the brightness of the light emitted from the light source 11 with reference to the detection result and the correspondence table stored in advance.

<9. Eighth Embodiment>
Next, an automatic transaction apparatus 1c according to an eighth embodiment of the present invention will be described. As described in the seventh embodiment, if the luminance of the light from the light source 11 out of the light from the display unit 12 that reaches a certain viewpoint and the light from the light source 11 is higher, the display unit 12 Are offset, and the display content of the display unit 12 is difficult to see. That is, the viewing angle of the display unit 12 can be controlled by adjusting the luminance of the light from the display unit 12 and the luminance of the light from the light source 11.

  Adjustment of the viewing angle of the display unit 12 will be described with reference to FIGS. FIG. 22 is a cross-sectional view of the operation display unit according to the present embodiment. In the present embodiment, a case where the viewing angle θ1 from the display unit 12 shown in FIG. 22 is controlled to a narrower angle and the viewing angle θ2 will be described as an example.

  FIG. 23 is a block diagram of an automatic transaction apparatus 1c according to the present embodiment. As shown in FIG. 23, the automatic transaction apparatus 1c includes a receiving unit 24, a brightness adjusting unit 25, a light source 11, and a display unit 12. The receiving unit 24 receives an instruction to adjust the width of the viewing angle of the display unit 12. For example, an instruction to widen / narrow the current viewing angle is accepted. The luminance adjusting unit 24 adjusts the luminance of at least one of the light source 11 and the display unit 12 according to the instruction received by the receiving unit 24 and controls the viewing angle of the display unit 12.

  For example, when the current viewing angle is θ1 shown in FIG. 22 and the receiving unit 24 receives an instruction to narrow the viewing angle of the display unit 12, the brightness adjusting unit 25 sets the brightness of the light source 11. Adjustment to increase or / and adjustment to lower the luminance of the display unit 12 is performed, and the viewing angle is controlled to θ2.
