Description

  The present invention relates to a display device used for a terminal device such as an automatic teller machine (hereinafter referred to as ATM) installed in a bank or a convenience store or an information terminal installed in a public institution, for example. The present invention also relates to a display device that includes a visually recognizable direction adjusting unit and that can display a screen only to a user.

  In recent years, ATMs are installed not only in banks but also in places other than banks such as convenience stores, and the places where they are used are expanding. In these various terminal devices, a touch panel is arranged on a display screen that displays input operation keys. The input operation by the user is performed by the user touching the touch panel.

  Among such terminal devices, many terminal devices installed in banks have a display screen arranged horizontally. A terminal device installed outside the bank generally has a display screen arranged vertically. In this case, the arranged height is often arranged at a height that is easy for general adults to use.

  On the other hand, the account number and balance displayed on the screen during the ATM operation may be peeped from the side by another person. And by this peep, the case where a user is involved in a crime is increasing. Such a case is a big problem in banks and the like.

  In order to prevent such peeping, many terminals adopt a method of preventing a screen from being seen even if peeping from the side beyond a certain angle, such as attaching a polarizing film to a display screen.

  For example, a data input device that prevents peeping on the display screen from the side has been proposed (see Patent Document 1). In this data input device, an optical polarizing plate is provided on a display screen for displaying an input key image such as a password. This restricts how the display screen is viewed. The purpose of this data input device is to prevent peeping by a third party from the viewing angle in the lateral, oblique direction before the user's back direction.

In addition, a terminal device that automatically adjusts the viewing angle has been proposed as a way of making the display content better visible only to the user (see Patent Document 2). This terminal device detects the amount of light incident on the display screen, and variably moves the display screen from the user's visual field range to an angle that is most easy to see based on the detection information. This makes it easy for the user to see the display screen.

  A polarizing film or the like that is pasted on a display screen as in the prior art needs to be pasted on a portion that a user touches for input. For this reason, it is considered that the sensitivity of the touch panel is lowered due to the adhered polarizing film and the dirt of the polarizing film, and there is a concern that the operability of the user is lowered.

  Further, when an optical deflection plate as in Patent Document 1 is used, it is mainly possible to prevent peeping in the left-right direction, that is, obliquely behind the user, but it is impossible to prevent peeping in the vertical direction. . In this vertical peeking, the display screen is usually hidden by the user's back, so it seems that no special measures are required. However, for example, users such as children with short stature and wheelchair users need to look up at the display screen from the bottom because their eyes are lower than those of normal adults. Therefore, there is a difference in the height of the line of sight from the person who is peeping, and it is possible to peep from the position on the same line connecting the terminal and the user. As a result, a situation occurs in which a display screen hidden by the back of a normal user is exposed to others.

  Here, it is conceivable to apply a method using a polarizing film or an optical deflecting plate in the vertical direction as in the prior art and Patent Document 1. However, when a polarizing film or an optical deflection plate is used, the visible range is fixed. For this reason, it is not possible to cover both the high eyes of normal users and the low eyes of children and wheelchair users.

  Further, in the case of a method of adjusting the display screen itself to an appropriate angle as in Patent Document 2, even if it is possible to avoid a decrease in visibility with respect to the height of the line of sight, peeping from behind can be completely prevented. I can't.

  An object of this invention is to provide the display apparatus which can prevent another person's peeping, ensuring favorable visibility with respect to the user of various eye height in view of the above-mentioned problem.

  The present invention is a display device including an input detection unit that detects a user input and a display unit that displays an image, and is displayed on the display unit between the input detection unit and the display unit. The display device includes a visible direction adjustment means for adjusting a visible direction in which the displayed content can be seen.

  According to the present invention, it is possible to provide a display device capable of preventing others from peeping while ensuring good visibility for users of various eye heights.

  An embodiment of the present invention will be described below with reference to the drawings. This embodiment relates to an automatic transaction apparatus such as an ATM used in a financial institution system such as a bank system.

  The operation unit 2 has screen display and key input detection functions. And the operation part 2 displays the guidance screen of transaction operation, and the content which the user input, when the user of the automatic transaction apparatus 1 mainly transacts, and the user's operation and the key input pressed with the finger | toe Accept. The liquid crystal display unit 201 in the operation unit 2 performs screen display. The touch panel 203 in the operation unit 2 detects user key input.

  As shown in FIG. 4, the liquid crystal display unit 201 and the touch panel 203 are overlapped with a predetermined gap. Various information can be displayed by the liquid crystal display unit 201, and pressing of various items included in the display screen can be detected by the touch panel 203.

  In addition, the operation unit 2 illustrated in FIG. 2 has a function of adjusting the visible direction by a user operation. Specifically, when the user operates the viewing angle adjustment dial 4, the viewing angle adjustment device 202 operates so that only the user can see the display content of the liquid crystal display unit 201.

The card mechanism unit 3 executes a user card insertion or ejection operation, a card magnetic stripe or IC chip read or write operation, a card embossed portion image read operation, and the like.

The banknote deposit / withdrawal mechanism 6 has a cash deposit / withdrawal function, a cash discrimination / conveyance function, and a storage function.

FIG. 5 is an explanatory diagram showing the configuration of the viewing angle adjusting device 202.
The viewing angle adjusting device 202 includes a plurality of viewing angle adjusting plates 251 and a viewing angle adjusting plate operating device 252.

  The visual field adjustment plate 251 is formed in a horizontally long and thin plate shape. A plurality of the visual field adjustment plates 251 are arranged in parallel in the vertical direction and configured in a blind shape. The horizontal width of the visual field adjustment plate 251 is formed wider than the effective display range 201 a of the liquid crystal display unit 201. Accordingly, the visual field adjustment plate 251 is arranged over the entire width of the effective display range 201a. The plurality of visual field adjustment plates 251 are attached so as to be sandwiched between the two visual field adjustment plate operating devices 252.

  The visual field adjustment plate operating device 252 is formed in a vertically long bar shape, and is arranged in parallel on the left and right. The two visual field adjustment plate operating devices 252 are arranged on the outer left and right sides of the effective display range 201a of the liquid crystal display unit 201. Therefore, the user can see the image displayed on the liquid crystal display unit 201 without hiding the effective display range 201a. Then, both ends of the above-described visual field adjustment plate 251 are connected to the two left and right visual field adjustment plate operating devices 252 by attachment shafts C, respectively.

  In addition, the visual field adjustment plate operating device 252 has a rotation detection function that receives an electrical signal from the visual field angle adjustment dial 4 and detects the rotation direction and the rotation amount of the visual field angle adjustment dial 4. And it has the function to rotate the visual field adjustment board 251 centering | focusing on the attachment axis | shaft C according to a rotation direction and rotation amount.

  With this configuration, when the user operates the viewing angle adjustment dial 4, the visual field adjustment plate 251 is rotated by the visual field adjustment plate operating device 252, so that the visual field adjustment plate 251 is in a visible direction that matches the viewing direction of the user. Can be adjusted.

FIG. 6 is an explanatory diagram for explaining the operation of the visual field adjustment plate 251 provided in the visual field angle adjustment device 202. With reference to FIG. 6, it will be described that the content of the liquid crystal display unit 201 is displayed only to the user when the user adjusts his / her visual field. FIG. 6 shows a viewpoint 61 for a tall user, a viewpoint 62 for a general user, and a viewpoint 63 assuming a child with a short height or a wheelchair user.
As shown in FIG. 6A, when a general user who is an ordinary adult adjusts the visual field adjustment plate 251, the visual field adjustment plate 251 is in a horizontal state as illustrated. In this state, only the line of sight from the viewpoint 62 of the general user reaches the liquid crystal display unit 201, and the line of sight from the viewpoint 61 of the tall user and the viewpoint 63 of the short user is viewed by the visual field adjustment plate 251. Blocked.

  As shown in FIG. 6 (B), when the visual field adjustment plate operating device 252 is adjusted to a short user having a viewpoint 63, the visual field adjustment plate 251 is inclined downward as shown in the figure. . In this state, only the line of sight from the viewpoint 63 of the user with short height reaches the liquid crystal display unit 201, and the lines of sight from the viewpoint 61 of the tall user and the viewpoint 62 of the general user are displayed by the visual field adjustment plate 251. Blocked.

  When the automatic transaction apparatus 1 is actually used, the user adjusts the visual field suitable for him / her by the visual angle adjustment dial 4 before starting the transaction. By starting the transaction after the adjustment, it is possible to prevent peeping during the transaction.

  With the configuration and operation described above, it is possible to provide a visually recognizable direction suitable for each user having a different height. Therefore, not only the conventional peeping prevention from the side, but also the peeping in the vertical direction can be prevented particularly for children and wheelchair users with low eyes.

  In addition, since the visual field adjustment plate 251 is disposed between the touch panel 203 and the liquid crystal display unit 201, good operability can be ensured without lowering the sensitivity of the touch panel 203.

  Further, since the change of the visible direction is realized by changing the angle of the visual field adjustment plate 251 without moving the position or angle of the liquid crystal display unit 201, the space necessary for installation can be reduced. That is, when the angle of the liquid crystal display unit 201 itself is changed as in the conventional example, it is necessary to provide a space for the liquid crystal display unit 201 to change the angle, which increases the size of the apparatus, but this can be avoided.

  In the first embodiment, the user adjusts the field of view with the viewing angle adjustment dial 4 before starting the transaction. However, the present invention is not limited to this, and a sensor may be provided. Specifically, for example, a customer sensor may be attached to the automatic transaction apparatus 1, and it may be determined by the customer sensor that a user has come before the automatic transaction apparatus 1, and the height of the user may be detected. In this case, the visual field adjustment plate operating device 252 may be automatically driven to adjust the angle of the visual field adjustment plate 251 in accordance with the detected height of the user. Thereby, even if the user does not adjust the viewing angle adjustment dial 4 himself, the display content of the liquid crystal display unit 201 can be prevented from being peeped from a different direction (vertical direction) from the user. improves.

  Moreover, even if the default position of the visual field adjustment plate 251 is set and the visual field adjustment plate 251 is adjusted, it may be configured to automatically return to the default position when the transaction ends. In this case, it is possible to avoid adjusting the visual field adjustment plate 251 more than necessary. In addition, if the default position is set to the height of the viewpoint of a general adult who accounts for the majority of users, the probability that the next user can use without adjusting the field of view even after a user with a low viewpoint adjusts the field of view. And the unnecessary adjustment of the visual field is reduced.

  Further, the entire liquid crystal display unit 201 is covered with the visual field adjustment plate 251 here, but only in a portion where information that should not be seen by a third party is displayed (for example, a portion displaying a password). A visual field adjustment plate 251 may be disposed.

As shown in the side view of FIG. 7, the visual field adjustment plate 251 may be made of a half mirror (magic mirror) material having a visible side 251a and an invisible side 251b on the front and back. The visual field adjustment plate 251 can visually recognize the other side of the visual field adjustment plate 251 from one direction A in which the visible side surface 251a is viewed, and cannot view the other side of the visual field adjustment plate 251 from the other direction B in which the invisible side surface 251b is viewed. In this case, in the normal state, as shown in the side view of the visual field adjustment plate 251 in FIG. 8A, the visual field adjustment plate 251 is arranged in a vertical state so that the visible side surface 251a is on the customer service side. At this time, when viewed from the user's viewpoint 81, the liquid crystal display unit 201 can be viewed through the visual field adjustment plate 251. At this time, the viewing angle in the vertical direction of the liquid crystal display unit 201 is wide, so that the display contents of the liquid crystal display unit 201 can be viewed not only from the frontal viewpoint 81 but also from the diagonally upper viewpoint 82 and the diagonally lower viewpoint 83. be able to.

  From this state, as shown in FIG. 8 (B), when the viewing angle adjustment dial 4 is operated and the viewable direction is adjusted, the view adjustment plate 251 rotates 90 degrees or more so that the invisible side 251b becomes the customer service surface. It will be in the inclined state of the near downward position located in the side (upper surface side). In this state, the viewing angle in the vertical direction of the liquid crystal display unit 201 is narrowed, and the visible direction is also restricted from obliquely below. Accordingly, at this time, the liquid crystal display unit 201 cannot be viewed from the user's viewpoint 81 and the user's viewpoint 82, and the liquid crystal display unit 201 can be viewed only from the user's viewpoint 83.

  Since other configurations are the same as those of the first embodiment, the same reference numerals are given to the same elements, and detailed description thereof is omitted.

  With the above configuration, the visibility in the normal state of FIG. 8A without adjusting the visible direction can be improved. That is, in the first embodiment, the portion of the liquid crystal display unit 201 where the image is not visible is generated in a horizontal line shape by the visual field adjustment plate 251 that is horizontal in the normal state. On the other hand, in the second embodiment, the visual field adjustment plate 251 is vertical in the normal state, and the liquid crystal display unit 201 can be seen through the visual field adjustment plate 251. Therefore, the image of the liquid crystal display unit 201 can be seen. No part occurs. Therefore, the visibility in the normal state can be improved as compared with the first embodiment.

  Further, in each of the above-described embodiments, the example in which the angle of the visual field adjustment plate 251 is adjusted by the rotation operation of the visual field angle adjustment dial 4 has been described, but various mechanisms can be employed instead of the visual field angle adjustment dial 4.

  Further, for example, a configuration may be adopted in which an attribute of a user (an attribute related to height) is input or detected, and the apparatus main body automatically adjusts the visible direction. Further, in the visible direction, the description is limited to the vertical direction. However, for example, when a plurality of units are installed in parallel, the viewing angle in the horizontal direction can be limited. Furthermore, it may be configured to be able to limit both the vertical and horizontal viewing angles.
