Description

  The present invention relates to a terminal device having an input unit in consideration of security, and more particularly to a terminal device used for card payment or the like.

  Conventionally, entering a PIN when making a payment using a bank automatic transaction device (ATM) or a card at a store, etc., may prevent the password from being seen by another person. Various things are used. For example, bank ATMs often use a touch panel to enter a PIN, but the number sequence displayed on the touch panel can be changed randomly each time it is entered, or entered at a cash register at a store. A simple wall made of a plastic plate or the like is formed around the numeric keypad of the terminal device used to prevent others from stealing the input of the password.

  Patent Document 1 illuminates an automatic transaction apparatus by providing a vertically long light source on the left and right of the operation unit in front of the person operating the ATM, on the left and right of the booth for storing ATMs used for deposits and withdrawals of banks, etc. At the same time, when looking at the operation from the side of the operator, the light from the light source provided on the left and right of the operation unit is likely to enter the eyes, so that a password or passbook is prevented from being seen. Japanese Patent Laid-Open No. 2004-228688 discloses a technique for lowering the illumination on a customer operation unit provided with a touch panel at a predetermined timing and preventing peeping from the surroundings regardless of the standing position. In the ATM operation / display screen, when prompting the input of a personal identification number, it is usually prompted to input the personal identification number by displaying a screen with a numeric key or different tone and brightness. It is. In addition, in a small device such as a mobile phone, there is a device that illuminates an operation button of the device and prompts an input, as shown in Patent Document 3, in order to prompt an operation.

  However, those that prompt the input by illuminating the operation buttons cannot be used for inputting a personal identification number or the like because the buttons pressed by those other than the surrounding users can be easily seen. In addition, banking ATMs, etc. that control the lighting near the operation unit can be configured only when the device is a stationary bank ATM, so there is no effect of preventing peeping. It could not be applied to possible small devices. Further, the cited document 1 and the cited document 2 control the brightness of the display unit and the surrounding brightness in order to prevent peeping. There was a possibility of becoming difficult. In addition, the entire apparatus becomes large.

  The present invention has been made to solve such a problem. The object of the present invention is to prompt the input of the operation unit and to reduce the power used even for a small device that can be moved. It is an object of the present invention to provide a terminal device and a light emission control method for the terminal device that prevent a person from peeping.

  In order to solve such a problem, the terminal device of the present application includes an operation unit, a shield unit provided around the operation unit, a light emitting unit that is covered with the shield unit and illuminates the shield, and the operation unit And a controller that makes the illumination of the shield part by the light emitting part weaker than that at the time of input by the operation part.

  With this configuration, the shield is lit only when necessary, prompting input to the operator, and even if it is a small device that can be moved, while looking at the third party while reducing power consumption Can be prevented.

  The control unit may turn off or illuminate the light emitting unit in the standby mode and make the illumination of the shield unit by the light emitting unit stronger than that in the standby mode when operated by the operation unit.

  With this configuration, since the shield is lit only when necessary, the operator can be urged to input, and even a small device that can be moved can be used to look into a third party while reducing power consumption. You can prevent seeing.

  The control unit returns the illumination of the shield unit by the light emitting unit to the brightness in the standby mode when a predetermined time has elapsed after the illumination of the shield unit by the light emitting unit is made stronger than the standby mode. May be.

  With this configuration, since the shield is lit only when necessary, the operator can be urged to input, and even a small device that can be moved can be used to look into a third party while reducing power consumption. You can prevent seeing.

  The control unit returns the illumination of the shield unit by the light emitting unit to the brightness in the standby mode when a predetermined time elapses after the illumination of the shield unit by the light emitting unit is made stronger than the standby mode. You may do it.

* 0006, 0014, 0021 at the time of application
With this configuration, a shield part brighter than the inside of the one that tries to peek at a relatively dark operator's hand (that is, the operation part inside the shield part) gets into the eyes of the one who tries to peek. For this reason, since the iris of the person who is looking through is narrowed down by the glare and the operation part looks dark, it is difficult to see the movement of the operator's finger and it is difficult to see the operation. The operator can input without feeling dazzling.

  The input device and the terminal device of the present invention are for solving such a problem. The input device and the terminal device prompt the operator to input and operate even if the device is a small device that can be moved while reducing power consumption. It is possible to realize a high-security terminal that is difficult to look into for a person who wants to look into the section.

  An embodiment for carrying out the present invention will be described with reference to the drawings.

  In this example, a terminal device that can be used on a desk or can be input by hand is used to describe a terminal device with reference to FIGS.

  First, the external appearance of the terminal device 4 is shown in FIG. In FIG. 1, the casing 1 of the terminal device 4 includes an upper casing and a lower casing. An operation unit 2 for inputting a personal identification number or the like is provided in a portion close to the operator of the terminal device 4. A shield 6 is provided around the operation unit 2 to illuminate the LEDs 41A and 41B as light sources and to prompt the operator to input keys on the operation unit 2 with light and to prevent a third person from peeping. The operator performs the input operation by placing the portable terminal (pin pad) 4 on the table or holding it with one hand.

  FIG. 4 shows the configuration of the terminal device of this embodiment. The terminal device is a small device used for inputting a password or the like at the time of card payment. The terminal device is connected to a storage unit 81 for storing data and programs in the housing 51 and to an external communication network 86 to communicate with the payment center 87. The external communication unit 82 to be performed, the input unit 2 and the card communication unit 5 installed on the surface of the housing, the display unit 3 that can be confirmed by the operator, the display unit is covered, and the LED 41A and the LED 41B receive light from the terminal device and the operation unit It has a shield 6 that illuminates. The shield 6 includes a left side surface 6L, a right side surface 6R, and an upper surface 6.

  Further, the display unit 3 is easy to confirm from the operator, and the card communication unit 5 that reads / writes to / from the IC card is easy to confirm during the operation of holding the card. 3 and the card communication unit 5 are arranged in this order. The LED 41 serving as a light source for shining the shield is arranged in the vicinity of the shield so that the shadow of the finger is not reflected on the shield. At the position shown in FIG. 2, the center of the optical axis of light is directed slightly inside the shield end face 21 and the end face 22. The positions of other LEDs are preferably near the shield at the edge of the operation unit. The control unit 83 controls the LED 41 that is the shield illumination to emit light to the shield 6. Here, it is assumed that the control unit 83 appropriately controls the brightness to prevent peeping, the brightness to prompt input, and the brightness suitable for operation. These control programs and information necessary for control and communication are stored in the storage unit 81. The control unit controls all the configurations of the terminal device 4.

  Further, the terminal device 4 receives the sales amount to be settled with a card from the point of sale register (POS) 85, which is a cash register, through the second external communication unit 84. When the terminal device 4 receives the payment amount from the POS and, if necessary, the card information to be used, the terminal device 4 displays the information on the display unit 3. The user confirms the settlement amount displayed on the display unit 3 and, if the amount is valid, holds the contactless IC card (not shown) over the card communication unit 5. The terminal device 4 reads information necessary for payment from the IC card and communicates with the payment center 87 via the communication network 86 to make payment, but communication with the payment center 87 or storage is a card that can be settled. If the settlement is possible by collating with the black list in the section 81, the display section is prompted to input a password. At this time, illumination of the shield 6 may be started in conjunction with a display requesting input of a password. Further, it is preferable to display “*” on the display unit 3 every time the key of the operation unit 2 is pressed to indicate to the operator that the input is accepted.

  The operation of the terminal will be described in detail with reference to FIG. First, when the terminal 4 is turned on, the inside of the apparatus is initialized (ST1). At this time, the light of the shield is off (OFF), but the shield may be weakly lit here. Is turned off or weakly lit (ST2). The power-off is an operation at the end of the work or at the time of closing the store (ST3), and normally a standby mode for waiting for the IC card is entered. At this time, standby of the IC card may be started by a signal from the POS 85 (ST13) ( ST4). When the IC card is held over and communication is performed with the IC card (ST4), an operation for inputting a personal identification number is required depending on the IC card (ST5). When the operation becomes necessary, the control unit 83 lights the shield 6. If the shield 6 is already weakly lit, the illumination of the shield 6 is increased (ST6). When all the input digits of the personal identification number are input, the control unit 83 determines that the input is complete (ST8), and turns off the light of the shield 6. In addition to this, the determination of the completion of the key input may be performed using a signal from the POS that the execution key has been pressed.

  If the operator forgets the password, it is forcibly returned to the standby mode when a predetermined time elapses with a timer (ST11). The terminal that has obtained the password is encrypted and sent from the external communication unit 82 to the settlement center 87 via the communication network 86. If the password is correct, the settlement center 87 performs a settlement process and sends the result to the terminal 4 via the communication network 86. Is returned (ST9). Communication with the settlement center 87 is not essential for each settlement. The control unit 83 reads the balance recorded on the card with the card communication unit 5, refers to the list of cards that cannot be traded in the storage unit 81, and then reads the balance The payment amount may be subtracted from the card, written to the card from the card communication unit 5 to complete the payment, and transmitted to the payment center 87 when the day's business is completed. At the end of the business, a standby mode (turns off the power from ST29 (turns OFF) so that the settlement is not interrupted).

  Here, details of the shield will be described. The shield 6 is translucent and the inner surface is treated as a frosted glass. LEDs 41A and 41B for illuminating the shield are provided at the positions shown in FIGS. 2 and 3, and these LEDs have the strongest portion of the radiated light in front of the shield 6 (on the operator side, the left side in FIG. 1). It is directed to the vicinity of the shield end faces 21 and 22.

  Further, vertical irregularities are provided on the inner surface of the shield 6 so that light is diffusely reflected to the operation unit so that the operation unit is evenly illuminated. For this reason, the light incident on the shield is scattered and emitted from the frosted glass surface, so that the outside of the shield is uniformly brightened. Furthermore, it is more effective if the inside of the shield is processed into a full-lens shape so that the vicinity of the end of the shield becomes brighter in combination with the arrangement of the LEDs 41A and 41B. The shield upper portion 6c is made of a transparent member so that the light entering the first shield side surface 6R and the second shield side surface 6L is guided to the upper portion by reflection within the shield so that the shield upper portion 6c shines. Although not shown in the drawing, the same LED 41A and LED 41B may be provided at the base of the shield upper portion 6c.

  The shield configured in this manner cannot see the operation unit from below the visible range shown in FIG. 6 and has an effect of preventing peeping. The visible range limit 10 has a shape raised to the operator side because it is preferable to pay particular attention to peeping from the left and right.

  The operation unit 2 existing inside the shield 6 is lightly reflected by the LED 41A, 41B on the outer surface of the frosted glass-like shield 6 and indirectly illuminated. Since it illuminates the hand, it is suitable for the operator. The inner part of the shield that receives the light from the LED is preferably formed in a saw shape so that the incident angle of light from the LED is small so that total reflection of light does not occur. Moreover, since the LED is directed outward from the front, light that is relatively stronger than the operator's hand is radiated to the outside of the shield, and when looking at a relatively dark hand, a shield that is brighter than the inside will be visible. I have to. For this reason, the iris of the person who is looking through is narrowed down and the operation unit looks dark, making it difficult to see the operation.

  Since the shield hides the finger operated from the line of sight from the outside, as shown in FIGS. 1 and 2, the shield end surfaces 21, 22, and 23 of the shield 6 are the surfaces of the shield 6. It faces in the direction of For this reason, the light of the LED reflected by the shield does not go in the direction of the operator's line of sight, and the operator feels no glare.

  As shown in this embodiment, since the brightness of the narrow range covered with the shield of the operation unit is different from the brightness of the shield, the entire apparatus can be made compact and can be mounted on portable equipment. Since the brighter shield is compactly packed near the operation unit, it can be expected to have a higher effect of preventing peeping than the conventional one, and the operation unit is shown to the operation unit with the illumination of the shield. You can also prompt for input.

  In Example 2, the display unit 3B is also installed inside the shield 6, and the appearance of the terminal device in this case is shown in FIG. The configuration other than the display unit is the same as that of the first embodiment. In this case, since the display unit 3B is installed at the back of the shield, even if the entered password is displayed, it cannot be seen, so information such as the entered password is displayed on the display unit 3B and erroneously entered. It is also possible for the operator to determine the input after confirming whether there is any error, and this configuration can reduce input mistakes.

  In Example 3, a shield 6 provided with a light guide plate 61 is shown in FIGS. The light guide plate 61 uses the total reflection of light to allow the light of the LEDs 41C and 41D to reach the end of the shield, and is effective in brightly illuminating the vicinity of the shield end surfaces 21 and 22 of the shield 6 where light is difficult to reach. Further, since the light from the LEDs 41C and 41D enters substantially perpendicular to the end face of the light guide plate 61, total reflection is hardly caused at the light entrance, and the shield 6 can be efficiently illuminated.

  8 and 9, the configuration other than the shield 6 having the light guide plate 61 is the same as that of the first embodiment. FIG. 7 is a top view of a cross section taken along the cutting plane BB ′ shown in FIG. Here, the light guide plate 61 is widened in the vertical direction toward the end of the shield 6 (the end on the operator side) in accordance with the radiation angle of the light from the LED, and the guided light is near the end. A slope as shown in FIG. 6 is provided so as to diverge toward the outside of the shield 6, and the entire surface is mirror-finished so that light is easily totally reflected.

  The light guide plate 61 and the inside of the shield 6 (on the operation unit side) are mirror-finished so that light is totally reflected, but the outside of the shield 6 is processed into a frosted glass so that total reflection does not occur. Since a part of the guided light is emitted to the outside, the entire shield is emitted to the far end from the light source, so that the light guided by total reflection is emitted and uniformly radiates to the end of the shield 6. Effectively prevent. Illumination on the operation unit side is moderately illuminated by light leaking from the external frosted glass surface, but if part of the light guide plate is processed into frosted glass, the light will be totally reflected at that part. Because it leaks out, it can be used as a local illumination.

  Moreover, as shown in FIG. 10, the case where the electroluminescent light-emitting body (EL light-emitting body) is stuck inside the shield and the whole shield is made to shine is shown. Since the EL light emitters 62 and 63 emit light with a uniform light amount, an arbitrary place can be illuminated with arbitrary brightness. Further, since the amount of light can be easily controlled by the applied voltage and frequency, it is possible to obtain a shield having a simple structure and easily adapted to ambient brightness. In FIG. 10, shields such as an EL light emitter 62 that emits light toward the outside of the shield 6 and an EL light emitter 63 that emits light toward the inside are provided, and the point that the light is increased or decreased by a signal from the control unit is as described above. This is the same as the LED shown in the example. Except for the configuration other than the EL light emitter, the configuration is the same as that of Example 1. In addition to the above, it is also preferable that the shield itself emits light by applying a blue light emitting diode, an ultraviolet light emitting diode or the like to the shield charged with a fluorescent material.

  As described above, the present invention takes security into consideration in order to promptly input to the operator and effectively prevent a third person from peeping while reducing power consumption even if movement is possible. It is possible to provide an input device used for card settlement or the like or a terminal device for performing settlement.
