However, when this touch panel device malfunctions, the automatic transaction device cannot determine that the touch panel device is malfunctioning and can only recognize that the touch panel device is not pressed. As a result, regardless of whether the automatic transaction apparatus is displaying a screen in which a transaction is possible, there is a problem that the customer cannot actually trade.

An object of the present invention is to accurately determine a failure when a touch panel device has a failure, and to change the display to effectively utilize the functions of the touch panel device as much as possible when determining that the failure has occurred. .

In order to achieve the above object, the present invention counts the number of times of input of a cancellation key by a customer without inputting a predetermined digit in inputting a password, and the number of times is a predetermined threshold within a predetermined period. If it exceeds, it is determined that the touch panel device is broken.

In the present invention, when it is recognized that an input digit is insufficient in inputting a password, the present invention determines that the touch panel device is broken by measuring the interval time of the input digit.

Furthermore, the present invention is a countermeasure when the above-described failure of the touch panel device is judged, and copes by moving the display of the key input effective area to another position on the touch panel device.

The automatic transaction apparatus according to claim 1 displays an information input key and a cancel key in a key input valid area on a screen, detects coordinates indicated in the key input valid area with a sensor, and corresponds to the corresponding input instruction coordinates. An automatic transaction apparatus having a display device for determining a key input, comprising: counting means for counting the number of times said cancel key has been input, and said counting value when the count value of said counting means exceeds a threshold within a predetermined time; And determining means for determining the apparatus as a failure.

The automatic transaction apparatus according to claim 2 displays a password input key and a cancel key in a key input valid area on the screen, detects coordinates indicated by the sensor within the key input valid area, and corresponds to the corresponding input instruction coordinates. An automatic transaction apparatus having a display device for discriminating key input, comprising: counting means for counting the number of times said cancellation key is input without inputting a predetermined digit at the time of password input, and counting of said counting means within a predetermined time period; If the value exceeds the threshold, it has determination means for determining the display device as a failure.

The automatic transaction apparatus of claim 3 further has control means for controlling the automatic transaction apparatus of claim 1 to move the display of the key input valid area when the determination means is determined to be a failure.

The automatic transaction apparatus according to claim 6 displays a password input key and a cancel key in a key input valid area on the screen, detects coordinates indicated in the key input valid area with a sensor, and corresponds to the corresponding input instruction coordinates. An automatic transaction apparatus having a display device for determining key input, comprising: determining means for determining that a predetermined digit is not input at the time of password input and that the cancel key is input, and an interval time between input digits in password input; Measurement means for measuring, and control means for determining the display device as a failure from the determination result of the determination means and the measurement result of the measurement means.

The automatic transaction apparatus of claim 7 further has control means for further controlling to move the display of the key input valid area when it is determined that the failure has occurred with respect to the automatic transaction apparatus of claim 6.

According to the present invention, since the number of times the cancel key is input is counted and it is determined as a failure when the count value exceeds a threshold value, it is possible to easily determine that the touch panel device has a failure as an automatic transaction device. In addition, when it is recognized that the input digits are insufficient in the input of the password, the failure is determined by measuring the interval time of the input digits, and therefore, it is possible to easily determine the failure of the touch panel device as an automatic transaction apparatus.

In addition, when the determination means judges that the touch panel apparatus has failed, the display of the key input area is moved to another position on the touch panel apparatus to display it, and thus the screen of the transactionable state is displayed. It has the effect of being able to actually trade, and furthermore, the automatic trading device can prevent the occurrence of a condition that the customer is not actually able to trade, regardless of displaying the screen of the tradeable state. It has the effect that it can contribute to the improvement of service.

In the description of FIG. 2, the description of the same reference numerals as those in FIG. 1 is omitted as the same components. 18 in the same figure is a control part which controls each part of ATM1. It has a memory section 16 serving as a storage section composed of a RAM, a ROM, a hard disk, or the like, in which a control program is stored, and an interface section (not shown) which is a connection port with a host computer. The ATM 1 transmits / receives a transaction such as a deposit transaction, a payment transaction, a currency exchange transaction, etc. via a communication line (not shown) and transmits and receives with a host computer (not shown).

3 is an explanatory diagram of a touch panel device according to the present invention. 31 is a transparent operation surface of the touch panel device 11, and when a customer who does not show, for example, a numeric key or the like displayed on the touch panel device 11 presses with his fingertips, the X coordinate detection circuit 32 and Y coordinate detection are performed. By the circuit 33 and the touch panel detection circuit 34, the XY coordinates on the operation surface 31 are detected.

4 is a flowchart illustrating the best mode of operation for practicing the present invention. First, the control unit 18 of the ATM 1 controls the touch panel device 11, the touch panel device 11 displays a password input screen, and prompts the customer to input a password (S101). ). When the customer enters the password, the control unit 18 stores the entered digit and checks whether four digits have been pressed (S102). If the four-digit password is pressed, the control unit 18 controls the touch panel device 11 to shift to the next screen, and the touch panel device 11 displays the next screen as usual (S103).

In step 102, when four digits are not pressed, the controller 18 checks whether the cancel key is pressed by the customer (S104). If the cancel key is pressed, the transaction ends in the middle, but the control unit 18 separately counts the number of times the corresponding cancel key is pressed (S105). The count of the cancellation key is performed for a predetermined time, for example, eight hours. When the predetermined time elapses, the control unit 18 checks whether the number of times the cancel key is pressed exceeds the predetermined threshold value (S106). The predetermined threshold value is, for example, the ATM 1 which normally has 200 transactions in 8 hours, for example, when the cancel key is pressed 20 times of 10%.

In step 106, when the number of cancellations has not exceeded the threshold, the control unit 18 continues the normal processing (S107). On the other hand, when the number of cancellations exceeds the threshold, the control unit 18 determines that the touch panel device 11 is broken (S108).

According to the best mode for carrying out the invention as described above, since the password is not pressed four digits and the number of presses of the cancel key exceeds the threshold, it is determined that the failure occurs, so that the touch panel device 11 is easily provided. ) Can be determined to be a failure, and as a result, the automatic trading apparatus can prevent the occurrence of a condition that the customer is not actually able to trade, regardless of displaying the screen of the transactionable state.

Example 1

In the best mode for carrying out the invention, the control unit 18 indicates that the touch panel device 11 is broken, provided that the password is not pressed four digits and the number of times the cancel key is pressed exceeds the threshold. In the first embodiment, however, when it is determined that the touch panel device 11 is broken under the same conditions, the effective area of the numeric keys in the touch panel device 11 is slightly moved to cope with it. In this case, the amount of movement calculates the average value of the coordinates of the push made several times with respect to the predetermined key, and when the average value is different from the center coordinate of the actual display of the key, the display of the key is moved by the difference. By fine-adjusting the display of the effective area in this manner, the screen that can be traded by the normal effective area is displayed. Hereinafter, Example 1 will be described with reference to FIGS. 5 and 6.

5 is a flowchart showing the operation of the first embodiment. First, the control unit 18 of the ATM 1 controls the touch panel device 11, and the touch panel device 11 displays a password input screen and prompts the customer to input a password (S201). ). The control unit 18 checks whether the customer has pressed a numeric key (S202). When the customer presses the numeric key, the control unit 18 stores the pressed coordinates in the storage unit (S203).

When the customer enters a password, the control unit 18 stores the entered digit and checks whether four digits have been pressed (S204). If the four-digit password is pressed, the control unit 18 controls the touch panel device 11 to shift to the next screen, and the touch panel device 11 displays the next screen as usual (S205).

If four digits are not pressed in step 204, the controller 18 checks whether the cancel key is pressed by the customer (S206). When the cancel key is pressed, the transaction ends in the middle, but the control unit 18 separately counts the number of times the cancel key is pressed (S207).

The count of the cancel key press is performed for a predetermined time, for example, 8 hours. When the predetermined time elapses, the control unit 18 checks whether the number of times the cancel key is pressed exceeds the predetermined threshold value (S208). A predetermined threshold value is the same as that of description of the best form for implementing the said invention.

If the number of times of cancellation in step 208 has not exceeded the threshold, the control unit 18 continues the normal processing (S209). Similarly, when the number of cancellations exceeds the threshold in step 208, the control unit 18 determines that the touch panel device 11 has failed (S210).

As a countermeasure against the failure of the touch panel device 11, in the first embodiment, the following control is performed. In other words, the average value of the predetermined number of times (for example, 20 times) is calculated from the push coordinates of the predetermined key stored in step 203. As will be described later, it is checked whether the average value differs from the center coordinate of the key (S211). When there is no difference in the step 211, that is, when a predetermined key is pressed 20 times, most pressing means that the center coordinate of the key is pressed. Therefore, in this case, since the pressing of the touch panel device 11 by the customer is performed according to the display of the touch panel device 11, the countermeasure for failure is performed separately (S212).

However, in step 211, if there is a difference between the average value of the push coordinates and the center coordinates of the corresponding key, that is, most of the customers are not pressed as indicated by the touch panel apparatus 11, and therefore the touch panel apparatus ( The display of the effective area of 11) is dealt with by moving (correcting) by the difference (S213).

6 is an explanatory diagram of movement of the display of the effective area of the first embodiment. The touch panel device 11 displays a password input screen. In the same figure, 41 denotes the effective area of the numeric key before the movement, and 42 denotes the effective area of the numeric key after the movement (after correction). 43 denotes a predetermined key, for example, the center coordinates 800 and 430 of the key "5", and 44 denotes an average coordinate of the key "5" pressed for a predetermined period in the display of the effective area 41 before the movement. 770, 390). 45 is a cancel key and 46 is a confirmation key.

In the same drawing, for example, the coordinate resolution of the entire screen of the touch panel device 11 is assumed to be 1 to 1024 in the X direction and 1 to 768 in the Y direction, and the control unit 18 controls the touch panel device 11. ), And the touch panel device 11 displays the numeric key 41 for password input as shown in the figure. For example, for the key of the number "5", the coordinate range is 751 to 850 in the X direction and 381 to 480 in the Y direction, and the center coordinate 43 of the key of the number "5" is (800, 430). . This is the so-called absolute coordinate.

On the other hand, the coordinate when the key of the number "5" is pressed is memorize | stored in step 203 as mentioned above, and the control part 18 calculates the average value of the predetermined number of times, for example, 20 coordinates. This is the mean coordinate 44 (eg 770, 390). Normally, when the numeric key "5" is pressed, naturally pointing to the center of the display, a coordinate close to the coordinates 800 and 430 of the central coordinate 43 of the numeric key "5" can be expected to be calculated as the average coordinate. . However, if the average coordinate 44 is coordinates (770, 390), the coordinates deviate by 30 coordinates to the left and 40 coordinates to the top. Therefore, the control unit 18 controls the touch panel device 11 to move the display of the numeric keys by the difference (X = 30, Y = 40).

As described above, according to the first embodiment, when it is determined that the touch panel device has a failure, the display of the key input area is moved to another position on the touch panel device and displayed. In this way, since the screen that can be traded by the normal effective area is displayed, the touch panel device can continue to operate, and the automatic transaction device keeps displaying the screen that can be traded, and the customer can actually trade the display. Can be. As a result, the automatic transaction apparatus can prevent the occurrence of a condition that a customer cannot actually trade regardless of displaying a screen of a transactionable state.

Example 2

In the first embodiment, when it is determined that the touch panel device 11 is malfunctioning, the display of the effective area of the numeric keys in the touch panel device 11 is slightly shifted, that is, the average value of the coordinates of the push made several times is changed. When it calculates and differs from the center coordinate of the actual display of the said key, it responds by moving a display of a key only by the difference. In contrast, in the second embodiment, the effective area of the numeric keys in the touch panel device 11 is moved and displayed so that the display after the movement does not overlap the display before the movement.

7 is an explanatory diagram of movement of the display of the effective area of the second embodiment. The touch panel device 11 displays a password input screen. In the same figure, 51 is an effective area of the numeric key before the movement, and 52 is an effective area of the numeric key after the movement. The effective area 52 of the numeric keys after the movement does not overlap with the effective area 51 of the numeric keys before the movement. At this time, 53 is a cancel key and 54 is a confirmation key.

The flowchart showing the operation of the second embodiment is the same as the flowchart showing the operation of the first embodiment described with reference to FIG. In the second embodiment, as in the first embodiment, when the numeric key of the password is not pressed by four digits and the cancel key is pressed, when the number of times the cancel key is pressed exceeds a threshold in a predetermined time, the controller 18 Determines the touch panel device 11 as a failure. Then, in step 213, the touch panel apparatus 11 moves and displays the effective area of the display of a numeric key so that the display after a movement may not overlap with the display before a movement.

As described above, according to the second embodiment, when it is determined that the touch panel device has a failure as well, the display of the key input area is moved to another position on the touch panel device to display it, that is, the automatic transaction device has a broken key. Since it is displayed in a valid key input area instead of being displayed in the input area, the touch panel device can continue to operate, and the automatic trading device continuously displays a screen in a tradeable state, so that the customer can actually trade as indicated. have. As a result, the automatic transaction apparatus can prevent the occurrence of a state in which the customer cannot actually trade regardless of displaying the screen of the transactionable state.

Example 3

In the above description, when the control unit 18 determines that the touch panel device 11 is broken, the numeric key of the password is not pressed four digits, and the number of times of cancel key is pressed when the cancel key is pressed is predetermined. Although the case where the threshold value was exceeded in time was determined to be a failure, in Example 3, the numeric key of the password was not pressed four digits, and after pressing the cancel key, the time interval of pressing three digits of the numeric key of the password was checked. It judges that it is failure by doing.

8 is a flowchart showing the operation of the third embodiment. First, the control unit 18 of the ATM 1 controls the touch panel device 11, the touch panel device 11 displays a password input screen, and prompts the customer to input a password (S301). ). Moreover, the control unit 18 starts measuring the time interval at which the customer presses the key (S302). Here, the customer presses the operation surface 31 while watching the numeric keys displayed on the display unit 35 of the touch panel apparatus 11. And the display part 35 becomes a blind display of a password like "****".

Thereafter, the control unit 18 checks whether the customer has pressed the numeric key (S303). When the customer presses the numeric key, the control unit 18 stores the interval time of the pressed key in the storage unit (S304).

When the customer enters the password, the control unit 18 stores the entered digit and checks whether four digits have been pressed (S305). If the four-digit password is pressed, the control unit 18 controls the touch panel device 11 to shift to the next screen, and the touch panel device 11 displays the next screen as usual (S306).

In step 305, when four digits are not pressed, the control part 18 determines whether a cancel key was pressed by a customer (S307).

When the cancel key is pressed, the transaction ends in the middle, but the control unit 18 separately performs the following processing. That is, the control unit 18 checks whether or not the three-digit numeric key is pressed (S308). When the three-digit press is not pressed, that is, the cancel key is pressed after the one-digit or two-digit numeric key is pressed, the control unit 18 performs a separate process (S310).

On the other hand, when the control unit 18 determines in step 308 that the three-digit numeric key has been pressed, the control unit 18 determines whether or not it can be estimated that the four-digit press has been pressed from the interval time of the pressing. It performs (S309). In this case, there are two cases. That is, as a 1st case, it is a case where "the space | interval time of 1st digit and 2nd digit and the space | interval time of a 2nd digit and a 3rd digit are almost the same time among 3 digits." This is because the customer pressed the numeric keys for three digits at almost normal intervals, and therefore, the numeric keys for four digits were probably pressed, but it is considered that the first digit or the fourth digit is lacking. Therefore, the control part 18 determines that the failure of the touch panel apparatus 11 was the reason that the cancel key was pressed.

In addition, it is a case where "the space | interval time of 1st digit and 2nd digit and the space | interval time of a 2nd digit and a 3rd digit are almost double or one half among 3 digits." This means that the interval time between the first and second digits and the interval time between the second and third digits is almost double or one-half of the three digits. This is a phenomenon that can occur when the second digit or the third digit is insufficient as a case of inputting, and therefore, like the first case, the control unit 18 is such that the cancel key is pressed. It is determined that the failure of (11) is the cause.

Therefore, the control unit 18 checks whether it can be estimated that four digits have been pressed from the pressing interval time, specifically, whether it corresponds to the first case or the second case (S309).

In step 309, when neither the first case nor the second case is applicable, that is, when it cannot be estimated that four digits have been pressed from the interval time of pressing, the control unit 18 performs separate processing. (S310).

On the other hand, if it corresponds to either the first case or the second case, that is, if it can be estimated that four digits have been pressed from the interval time of the pressing, the control unit 18 causes the touch panel device 11 to fail. It is determined that it is present (step 311).

As described above, according to the third embodiment, the numeric key of the password is not pressed four times, and after pressing the cancel key, it is possible to easily determine that the failure is made by checking the time interval of three-digit pressing of the numeric key of the password. As a result, the automatic transaction apparatus can prevent the occurrence of a condition that the customer is not actually able to trade, regardless of displaying the screen of the transactionable state.

Example 4

In the third embodiment, the controller 18 determines that the touch panel device 11 is broken, provided that the password is not pressed four digits and the cancel key is pressed. When it is determined that the panel device 11 is broken, the effective area of the numeric keys in the touch panel device 11 is slightly moved in the same manner as in the first embodiment. In this case, as in the first embodiment, the movement amount calculates the average value of the coordinates of the presses performed on the predetermined key several times, and moves the display of the key by the difference when it differs from the center coordinate of the actual display of the corresponding key. do. Detailed description is the same as in Example 1, and will be omitted.

Example 5

In the third embodiment, the controller 18 determines that the touch panel device 11 is broken, provided that the password is not pressed four digits and the cancel key is pressed. When it is determined that the panel device 11 has failed, the effective area of the numeric keys in the touch panel device 11 is moved and displayed so that the display after the movement does not overlap the display before the movement, similarly to the second embodiment. . Detailed description is the same as in the second embodiment and will be omitted.

In the above description, the "cancellation key" has been described, but the present invention is not limited to this. For example, when the branch name of the bank account destination is input by the "return key", that is, the direct deposit operation, the operation screen is displayed on the operation screen. Return to the screen in front of the screen, the key to re-enter from the name of the bank transfer destination financial institution, "correction key", that is, the key to delete all the characters entered so far and enter the deposit destination from the beginning, When a "one character correction key", i.e., a payment destination or the like is inputted, only one character has been inputted in error, and even a key for re-entering only one character has the same function as the "cancellation key". It is clear that it is included.

Moreover, the present invention is not limited to an automatic transaction apparatus installed in a financial institution, but the present invention has an operation display apparatus having a touch panel apparatus operated by a customer or a member, for example, an operation terminal such as a city hall, a ticketing device at a station, a check-in terminal at an airport It is clear that the apparatus, the ticketing apparatus of the lottery, and the like are included in the technical scope of the present invention.
