Description

  The present invention relates to a response time determination device, a program, a system, and a response time determination method, and more particularly, to a response time determination device, a program, a system, and a response time determination method for determining an operator's response time.

  Examples of scenes where it is necessary to determine the arousal state, which is one of the operators' qualifications, and to proceed with the processing include starting an automobile engine and stopping an alarm sound of an alarm clock.

  For example, in starting a car, the engine could be started unconditionally with the key. For this reason, there is a problem that a person in a sad state drives a car and an accident occurs. As a countermeasure against such a problem, there is a related technique in which a vehicle is equipped with a device for measuring blood alcohol concentration during vehicle operation so that the vehicle cannot be started when the blood alcohol concentration exceeds a threshold (for example, Patent Document 1).

  In addition, for example, there is a related technique for preventing the alarm sound of an alarm clock from being easily stopped. In this method, an alarm sound stop process is executed by inputting numbers randomly displayed on the display unit from the input unit (for example, Patent Document 2).

  As another related technique, there is a technique related to the key input response time measurement disclosed in Patent Document 3 or Patent Document 4.

  Furthermore, as another related technique, there is a technique for randomly changing the key arrangement of the operation unit as a security technique for peeping in the input of a password (for example, Patent Document 5).

  However, with the related technique described in Patent Document 1, driving of a car by a person who is sleep-deficient or mischief of an infant or the like cannot be detected. That is, there is a problem that the engine can be started as long as the person has not drunk, can turn the key, and can press the switch.

  In the related art described in Patent Document 2, there is a problem that even in a half-awake state, a prescribed operation can be performed after several attempts.

  The related techniques described in Patent Document 3 and Patent Document 4 are techniques related to response time measurement for an operation unit that can shorten the response time by proficiency, and a response that discriminates an arousal state that is the technical field of the present invention. Cannot handle time determination.

  The related art described in Patent Document 5 does not go out of security that prevents peeping, that is, manipulation by imitating, and a response that discriminates an arousal state that is also a technical field of the present invention. Cannot handle time determination.

  The objective of this invention is providing the response time determination apparatus, program, system, and response time determination method which solve the subject mentioned above.

  The response time determination device according to the present invention includes a plurality of input operation means for displaying an input symbol based on a display control signal and outputting an operation detection signal based on an input operation by an operator, and one or more specified specific operations. A selection means for selecting the input symbol including one or more expected input symbols, and any one of the input operation means including the input symbol including the one or more expected input symbols. Selection means for selecting whether to display on the display, display control means for outputting the display control signal corresponding to the input symbol including one or more selected expected input symbols to the selected input operation means, and operation Time monitoring means for monitoring whether the input operation of the expected input symbol by the operator is executed within a predetermined determination time based on the input of the detection signal.

  When the program of the present invention detects any one of one or more predetermined states, a process for selecting the input symbol including one or more expected input symbols and one or more expected inputs A process of selecting which input operation means to display the input symbol including a symbol, and a display control signal corresponding to the input symbol including the one or more selected expected input symbols The data processing means performs processing to output to the operating means and processing to monitor whether or not the input operation of the expected input symbol by the operator has been executed within a predetermined determination time.

  The system of the present invention includes a plurality of input operation means for displaying an input symbol based on a display control signal and outputting an operation detection signal based on an input operation by an operator, and one or more predetermined states in a predetermined state. When one of the states is detected, selection means for selecting the input symbol including one or more expected input symbols, and the input symbol including one or more expected input symbols are displayed on any of the input operation means. Selection means for selecting the display, display control means for outputting the display control signal corresponding to the input symbol including one or more selected expected input symbols to the selected input operation means, and an operation detection signal Time monitoring means for monitoring whether an input operation of the expected input symbol by the operator is executed within a predetermined determination time based on the input.

  The response time determination method of the present invention selects one of the input symbols including one or more expected input symbols when detecting any one of predetermined one or more specific states, and selects the one or more expected expectations. It is selected which input operation means to display the input symbol including the input symbol, and the display control signal corresponding to the input symbol including the selected one or more expected input symbols is selected in the selected input operation. And monitoring whether or not the input operation of the expected input symbol by the operator is executed within a predetermined determination time.

  According to the present invention, it is possible to determine eligibility including the operator's arousal state.

  Next, the present invention will be described in detail with reference to the drawings. First, expressions used in this specification will be described.

  The input symbol and the expected input symbol refer to symbols in a general sense such as numbers, letters, and figures that are physically displayed by a machine and visually distinguishable by a person.

  The input symbol is displayed on the input operation means of the present invention and defines the function of the corresponding input operation means. This corresponds to, for example, a keyboard marking for computer operation.

  The expected input symbol indicates a symbol that the response time determination device, program, system, or response time determination method of the present invention expects to be input by the operator at a specific timing. In other words, the operator operates the input operation means in which the expected input symbol is displayed as the input symbol at a specific timing by the response time determination device, program, system, or response time determination method of the present invention. Expected.

  The uppercase alphabetic suffix that follows the component name is attached to the same physically existing component for convenience of explanation, and does not indicate a difference in the function or operation of the component. For example, the input operation means A and the input operation means B are the same input operation means. For example, the expression “input operation means” includes both the input operation means A and the input operation means B without distinction.

  The selection request signal is a signal output from the time monitoring unit 114 and input from the selection unit 111. The display control signal is a signal output from the display control unit 113 and input from the input operation unit 115. The operation detection signal is a signal output from the input operation unit 115 and input from the time monitoring unit 114.

  Note that each unit described in the following embodiments may be realized by hardware, software, or a mixture of hardware and software.

  FIG. 1 is a functional block diagram of the first embodiment of the present invention. Referring to FIG. 1, a response time determination device 110 according to the first exemplary embodiment of the present invention includes a selection unit 111, a selection unit 112, a display control unit 113, a time monitoring unit 114, and an input operation unit 115. It consists of

  When the selection means 111 detects the selection request signal from the time monitoring means 114, the selection means 111 determines whether or not the selection of the last expected input symbol has been completed. The selection unit 111 selects an input symbol including one or more expected input symbols when the selection of the last expected input symbol is not completed. For example, the selection unit 111 reads one of one or more expected input symbols stored by a unit (not shown). For example, the selection unit 111 generates four random numbers as input symbols. Note that detecting the selection request signal is an example of detecting any one of one or more predetermined states. When the selection of the last expected input symbol has been completed, the selection unit 111 outputs a normal signal to a unit (not shown) that executes normal processing.

  The selection unit 112 selects the input operation unit 115 that displays each of the input symbols including one or more expected input symbols selected by the selection unit 111. For example, assume that one or more expected input symbols are “2” and the input symbols are “3”, “5”, “8”, and “9”. In this case, for example, the selection unit 112 selects the input operation unit D115 as the input operation unit 115 that displays “2” and the input operation unit C115 as the input operation unit 115 that displays “3”. Subsequently, for example, the selection unit 112 selects the input operation unit A115 as the input operation unit 115 that displays “5” and the input operation unit E115 as the input operation unit 115 that displays “8”. Subsequently, for example, the selection unit 112 selects the input operation unit B115 as the input operation unit 115 that displays “9”. Selection of the expected input symbol or each input operation means 115 for displaying the input symbol is performed by a predetermined algorithm. This algorithm can be selected at random, based on ergonomics, etc., so that the input operation of the expected input symbol by the operator takes time, or the input operation of the expected input symbol by the operator takes time. It may be selected so as not to be applied. Various other algorithms can be used depending on the application field.

  The display control unit 113 outputs each display control signal corresponding to an input symbol including one or more expected input symbols selected by the selection unit 111 to each input operation unit 115 selected by the selection unit 112. Hereinafter, the display control signal will be referred to as the display control signal. For example, the display control means 113 outputs a display control signal corresponding to “2” to the input operation means D115, a display control signal corresponding to “3” to the input operation means C115, and a display control signal corresponding to “5”. Each is output to the input operation means A115. Similarly, the display control means 113 outputs a display control signal corresponding to “8” to the input operation means E115 and a display control signal corresponding to “9” to the input operation means B115.

  The time monitoring unit 114 inputs an operation detection signal from the input operation unit 115. The time monitoring means 114 notifies the selection means 111 of a selection request signal when an operation detection signal is input in the initial state, that is, in a state where time measurement for time monitoring is not performed. The time monitoring unit 114 also starts timing when an operation detection signal is input in an initial state, that is, in a state where time measurement for time monitoring is not performed.

  In addition, the time which the time monitoring means 114 measures for time monitoring is called determination time. This determination time may be given by means not shown, or may be fixedly provided inside the time monitoring means 114. It should be noted that the time point when the operation detection signal is input in a state where the time monitoring unit 114 is not performing time monitoring is one example of the time point when the expectation input symbol is input. .

  The time monitoring unit 114 monitors whether or not an input operation of the expected input symbol is executed within the determination time. Then, the time monitoring unit 114 notifies the selection unit 111 of a selection request signal when the input operation of the expected input symbol is executed within the determination time. Further, the time monitoring unit 114 outputs an abnormality signal to a unit (not shown) that executes processing at the time of abnormality when the input operation of the expected input symbol is not performed within the determination time. Hereinafter, when described as an abnormal signal, the abnormal signal described here is indicated.

  The input operation unit 115 displays an input symbol based on the display control signal output from the display control unit 113. Then, the input operation unit 115 outputs an operation detection signal to the time monitoring unit 114 when an input operation is performed by the operator.

  Next, the operation of the first exemplary embodiment of the present invention will be described with reference to the drawings. FIG. 2 is a flowchart showing the operation of the first exemplary embodiment of the present invention.

  The input operation means 115 checks whether or not there has been an input operation on the input operation means 115 by the operator (step S100). If there is an input operation on the input operation means 115 by the operator (Yes in step S100), the input operation means 115 branches to step S101. If there is no input operation on the input operation means 115 by the operator (No in step S100), the input operation means 115 branches to step S100.

  The input operation unit 115 outputs an operation detection signal to the time monitoring unit 114 when the input operation is detected by the operator (step S101).

  When receiving the operation detection signal, the time monitoring unit 114 determines whether or not the determination time is being measured (step S102). When the determination time is not being measured (No in step S102), the time monitoring unit 114 starts measuring the determination time and outputs a selection request signal to the selection unit 111 (step S103). . Further, when the determination time is being measured (Yes in step S102), the time monitoring unit 114 outputs a selection request signal to the selection unit 111 (step S104).

  Upon receiving the selection request signal, the selection unit 111 determines whether the selection of the last expected input symbol has been completed (step S105). And the selection means 111 outputs a normal signal, when selection of the last expected input symbol is complete | finished (in the case of Yes of step S105) (step S106). In this case, the processing portion of the present invention is up to this point, and this normal signal is notified to a normal processing means (not shown), and processing is executed when the response is normally performed within the determination time. If the selection of the last expected input symbol is not completed (No in step S105), the selection unit 111 selects an input symbol including one or more expected input signals, and this information is sent to the selection unit 112. (Step S107).

  Upon receiving the information of the input symbols including the selected one or more expected input signals, the selection means 112 selects each input operation means 115 for displaying each, and passes this information to the display control means 113 (step S108). .

  The display control unit 113 receives information on the input symbol including one or more selected expected input signals and information on the selected input operation unit 115. Then, the display control means 113 outputs a display control signal corresponding to each of the input symbols including one or more selected expected input signals to each selected input operation means 115 (step S109).

  The time monitoring unit 114 checks whether or not the determination time has elapsed (step S110). When the determination time has not elapsed (No in step S110), the time monitoring unit 114 updates the time measurement (step S111). The time monitoring unit 114 outputs an abnormal signal when the determination time has elapsed (in the case of Yes in step S110) (step S112). In this case, the processing portion of the present invention has been described so far, and this abnormal signal is notified to an abnormal processing means (not shown), and the processing when the input is not completed within the determination time is executed.

  The input operation means 115 checks whether or not there has been an input operation on the input operation means 115 by the operator (step S113). If there is an input operation on the input operation means 115 by the operator (Yes in step S113), the input operation means 115 branches to step S101. If there is no input operation on the input operation means 115 by the operator (No in step S113), the input operation means 115 branches to step S110.

  According to the first embodiment of the present invention, the input symbol displayed on the input operation unit is appropriately changed at an appropriate timing, the input operation on the input operation unit is monitored, and whether or not the input symbol is input within the determination time. By confirming this, there is an effect that it becomes possible to detect the response ability of the operator and the arousal state.

  Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

  Referring to FIG. 3, the second embodiment of the present invention includes a seating detection unit 10, a hazard display unit 17, a response time determination device 19, and a target device control unit 20.

  The seating detection unit 10 detects that the operator is seated and notifies the response time determination device 19 of it. Since these detection means and notification means are techniques well known to those skilled in the art, their details are omitted.

  The hazard display unit 17 alerts the vicinity by issuing an alarm using sound, light, or the like according to an instruction from the response time determination device 19. Since these means for receiving instructions and hazard display means are techniques well known to those skilled in the art, their details are omitted.

  The control unit 20 of the target device is, for example, an engine control unit of a vehicle, and performs a necessary operation based on a signal from the response time determination device 19. Since the means for receiving the signal is a technique well known to those skilled in the art, the details are omitted.

  The response time determination device 19 includes a control unit 11, which is a data processing means that operates by program control, a backlight unit 12, a storage device 13, a specific number / character display unit 14, a timer circuit 15, and a variable. A number display / input unit 16 and a card reader unit 18 are included.

  The backlight unit 12 emits light from the back surface of the specific number / character display unit 14. The storage device 13 is a readable / writable storage device that stores information necessary for the control unit 11 to operate. The specific number / character display unit 14 is a liquid crystal display, for example, and displays characters and other information based on the control of the control unit 11. The timer circuit 15 measures a countdown time 201 (see FIG. 6), which is a determination time set by the control unit 11.

  FIG. 4 is a diagram of a configuration example of the variable number display / input unit 16. The variable number display / input unit 16 includes an input operation means 115 realized by a numeric display portion and a transparent button covering the numeric display portion.

  Hereinafter, the position 1 sensor 21, position 2 sensor 22, position 3 sensor 23, position 4 sensor 24, position 5 sensor 25, position 6 sensor 26, position 7 sensor 27, position 8 sensor 28 of the variable number display / input unit 16; The position 9 sensor 29 to the position 10 sensor 30 are referred to as “each sensor in the sensor group”.

  The card reader unit 18 confirms the mounting of the card based on an instruction from the control unit 11 and scans the contents of the card. This card is assumed to be an ID card such as an ID card, an employee ID card, a driver's license, or a membership card, which is realized by an IC card, which can identify an individual as an operator. In addition, it is assumed that a countdown time 201 corresponding to an individual who is an operator is recorded on this card. Hereinafter, when it is described as a card, it indicates the card described here.

  The control unit 11 includes an expected input symbol generation unit 116, an expected input symbol storage unit 117, an expected input symbol display instruction unit 118, a display input element selection unit 120, a display control signal output unit 121, and a normal process execution unit. 122, an abnormality process execution unit 123, a mistake monitoring unit 124, a timer control unit 125, and a determination time reading unit 128. The control unit 11 realizes the time monitoring unit 114 by controlling the timer circuit 15 with the timer control unit 125. The control unit 11 implements means for displaying the expected input symbol by instructing the specific number / character display unit 14 to display the content using the expected input symbol display instruction unit 118.

  The control unit 11 detects that the operator is seated by a notification from the seating detection unit 10. The control unit 11 checks whether or not a card is mounted on the card reader unit 18.

  The control unit 11 controls turning on and off of the backlight unit 12. The control unit 11 executes the initialization operation in the response time determination device 19 including the control unit 11 itself. The control unit 11 controls the card reader unit 18 to scan the card, and the determination time reading unit 128 reads data including the countdown time 201 and stores it in the storage device 13. The control unit 11 generates a random number string 204 (see FIG. 7A) by an expected input symbol generation unit 116 corresponding to the selection unit 111. Then, the control unit 11 stores the random number string 204 in the storage device 13 by the expected input symbol storage unit 117. The control unit 11 displays the numeric string 204 in the storage device 13 on the specific number / character display unit 14 by the expected input symbol display unit 118. The control unit 11 instructs the timer circuit 15 to start timing by the timer control unit 125.

  The control unit 11 uses the display input element selection unit 120 corresponding to the selection unit 112 to determine the arrangement of numbers 0 to 9 so as to display at random. Then, the control unit 11 sends the 7-segment display control signal of the numbers 0 to 9 whose arrangement has been determined to the variable number display / input unit 16 by the display control signal output unit 121 corresponding to the display control unit 113. The control unit 11 waits for notification of the key position detected by the button pressure from the variable number display / input unit 16.

  The control unit 11 updates (adds 1) the button pressure detection count 202 (see FIG. 6) stored in the storage device 13 every time it receives a notification of the key position where the button pressure is detected.

  The control unit 11 stores the number (referred to as the number S) displayed on the display unit of each sensor of the sensor group of the key position data notified from the variable number display / input unit 16 and the storage device 13. It is determined whether or not the first number (referred to as number T) in the number string 204 matches. When it is detected that the number S and the number T match, the control unit 11 shifts the number string 204 in the storage device 13 to the left (for example, shifts FIG. 7A to the left, and FIG. ), And a specific number / character display unit 14.

  The control unit 11 checks whether or not the numeric string 204 of the storage device 13 is empty. The control unit 11 causes the normal process execution means 122 to display on the specific number / character display unit 14 that the engine is ready to start. The control unit 11 notifies the control unit 20 of the target apparatus that it can be started by the normal process execution unit 122.

  The control unit 11 uses the error monitoring unit 124 to check whether the button pressure detection number 202 exceeds the specified number 209. Further, the control unit 11 uses the timer control unit 125 to check whether or not the countdown time 201 has elapsed in the timer circuit 15.

  The control unit 11 displays an error on the specific number / character display unit 14. The control unit 11 instructs the hazard display unit 17 to start and stop the hazard display by using the abnormality processing execution unit 123.

  Each display unit of each sensor in the sensor group displays a numeric string 204 based on an instruction from the control unit 11. Each sensor in the sensor group detects pressure.

  Based on the 7-segment display control signal received from the control unit 11, the variable number display / input unit 16 displays a number on the display unit of each sensor in the sensor group.

  The variable number display / input unit 16 notifies the control unit 11 of key position data corresponding to each sensor of the sensor group that has detected the pressure.

  Next, the operation of the second exemplary embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a flowchart illustrating the operation of the control unit 11 according to the second embodiment of this invention.

  When the seating detection unit 10 detects that the operator is seated, the control unit 11 starts the operation (step P1). The control unit 11 checks whether or not a card is mounted on the card reader unit 18 (step R1). When the control unit 11 detects that no card is mounted (No in Step R1), the control unit 11 branches to Step R1 (the card is waiting to be mounted).

  When the control unit 11 detects that a card is mounted (Yes in step R1), the control unit 11 issues a lighting instruction to the backlight unit 12. Then, the control unit 11 executes various parameter initialization in the control unit 11, initialization operation of the storage device 13, and clear operation of the specific number / character display unit 14 (step P2).

  The control unit 11 scans the card by the card reader unit 18 and reads data including a countdown time 201 (for example, 10 seconds). And the control part 11 stores this data in the memory | storage device 13 (step P3).

  For example, the control unit 11 generates a random digit string 204 of 10 digits (step P4). And the control part 11 stores this number sequence 204 in the memory | storage device 13, and displays it on the specific number and character display part 14 (refer Fig.7 (a), step P5).

  The control unit 11 sets the countdown time 201 in the timer circuit 15 and instructs the start of time measurement (step P6).

  For example, the control unit 11 determines the arrangement so that numbers “0” to “9” are randomly displayed on each sensor of the sensor group. And the control part 11 stores the determined arrangement | positioning in the position 1 sensor display number-the position 10 sensor display number 203 of the memory | storage device 13 (refer FIG. 6).

  The instruction to start timing is an example of detecting any one of one or more predetermined states. Further, the branch from step R5 to step P9 and the branch from step R6 to step P9, which will be described later, are similarly based on an example of detecting one of one or more predetermined states. It is a branch. Furthermore, although the same example is shown also in 3rd Embodiment and 4th Embodiment mentioned later, since it overlaps with the content demonstrated here, description in each location is abbreviate | omitted.

  Then, the control unit 11 sends a 7-segment display control signal corresponding to the numbers 0 to 9 whose arrangement is determined to be random to the variable number display / input unit 16 in the order of each sensor of the corresponding sensor group. Send. The variable number display / input unit 16 displays a number based on the received 7-segment display control signal (see FIG. 8, step P9). Then, the control unit 11 waits for notification of the key position detected from the variable number display / input unit 16 when the button pressure is detected.

  The control unit 11 that has been in a state of waiting for notification of the key position detected from the variable number display / input unit 16 uses the timer circuit 15 to check whether the countdown time 201 has elapsed (step R2). When the control unit 11 detects that the countdown time 201 has elapsed (in the case of No in step R2), the control unit 11 branches to step P7. When the control unit 11 detects that the countdown time 201 has not elapsed (in the case of Yes in step R2), the control unit 11 branches to step R3.

  The control unit 11 branched to step R3 checks whether or not the key position data corresponding to each sensor of the sensor group that has detected the pressure is notified from the variable number display / input unit 16 (step R3). When the control unit 11 detects that there is no notification of the key position data (No in step R3), the control unit 11 branches to step R2. If the control unit 11 detects that the key position data has been notified (Yes in step R3), the control unit 11 branches to step P10.

  The control unit 11 branched to step P10 adds 1 to the button pressure detection count 202 of the storage device 13.

  Next, the control unit 11 reads a specified number of times 209 (for example, 15 times) stored in advance in the storage device 13 and checks whether or not the button pressure detection number 202 exceeds the specified number of times 209 (step R4). When the controller 11 detects that the button pressure detection count 202 exceeds the specified count 209 (No in Step R4), the control section 11 branches to Step P7. When the control unit 11 detects that the button pressure detection count 202 does not exceed the specified count 209 (Yes in step R4), the control unit 11 branches to step R5.

  The control unit 11 branched to step R5 refers to the position 1 sensor display number to the position 10 sensor display number 203 (see FIG. 6) stored in the storage device 13, and displays the information at the key position of the notified key position data. It is checked whether or not the number being matched with the number at the beginning of the number string 204 stored in the storage device 13 (step R5). When the control unit 11 detects that these numbers do not match (No in Step R5), the control unit 11 branches to Step P9. When the control unit 11 detects that these numbers match (Yes in Step R5), the control unit 11 branches to Step P11.

  The control unit 11 branched to step P11 deletes the first number of the number string 204 stored in the storage device 13, and shifts the remaining number toward the beginning. Then, the control unit 11 displays the numeric string 204 on the specific number / character display unit 14 (see step P11 in FIG. 7B).

  Subsequently, the control unit 11 checks whether or not the numeric string 204 stored in the storage device 13 has become empty (step R6). When the control unit 11 detects that the numeric string 204 is not empty (No in step R6), the control unit 11 branches to step P9. If the control unit 11 detects that the numeric string 204 is empty (Yes in step R6), the control unit 11 branches to step P12.

  The control unit 11 branched to step P12 displays the fact that it can be started on the specific number / character display unit 14 (step P12). Subsequently, the control unit 11 notifies the control unit 20 of the target device that it can be started (step P13).

  The control unit 11 branched to step P7 performs hazard display for a certain period of time on the hazard display unit 17 (step P7), and displays an error on the specific number / character display unit 14 (step P8).

  FIG. 17 is a conceptual diagram of display transition of the specific number / character display unit 14 and the variable number display / input unit 16 according to the second embodiment of the present invention realized by the above operation.

  According to the second embodiment of the present invention, within the countdown time 201 stored in the card, it is specified from the variable number display / input unit 16 that changes at every input within the range of the input error of the specified number of times 209. If the specific number displayed on the number / character display unit 14 can be input, the control unit 20 of the target device can be started, and if it cannot be input, a hazard display is displayed. If so, the control unit 20 of the target device can be started, and if it is an abnormal operator such as a person who is in a drunken state or a person who is sleep deprived or an unsuitable operator such as an infant, the control of the target device is performed. The unit 20 cannot be started, and there is an effect that a warning can be given to the surrounding people and an abnormality can be noticed. Further, when data including the countdown time 201 is read from the card, the upper limit value (specified number 209) of the button pressure detection number 202 is read and set as the upper limit value of the button pressure detection number 202, so that the age of each individual can be adjusted. A flexible response time determination operation can be performed.

  Next, a third embodiment of the present invention will be described in detail with reference to the drawings. Note that in the description of the third embodiment, parts that are the same as those in the second embodiment and have already been described are redundant, and are therefore omitted to the extent that the flow of description is not obscured.

  Referring to FIG. 9, in the third embodiment of the present invention, the response time determination device 59 has a read-only storage device 61, and a part of the operation of the control unit 51 is the second embodiment. This is different from the operation of the control unit 11 of the response time determination device 19 of the form.

  The read-only storage device 61 stores a specific number string 205.

  The control unit 51 includes an expected input symbol reading unit 516 instead of the expected input symbol generation unit 116.

  Instead of the control unit 11 generating the random number sequence 204, the control unit 51 reads the specific number sequence 205 from the read-only storage device 61 by the expected input symbol reading unit 516 corresponding to the selection unit 111 and stores it. Store in the device 13.

  The control unit 51 replaces that the control unit 11 displays the numeric string 204 in the storage device 13 on the specific number / character display unit 14, and replaces “*” with the number of characters in the specific numeric sequence 205 in the storage device 13. It is displayed on the specific number / character display unit 14.

  Next, the operation of the third exemplary embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a flowchart illustrating the operation of the control unit 51 according to the third embodiment of this invention.

  Steps P1 to P3 are the same as the operation of the second embodiment of the present invention, and are therefore omitted.

  The control unit 51 reads a specific numeric string 205 (see, for example, FIG. 11A) stored in the read-only storage device 61 (step S4).

  Then, the control unit 51 stores the specific number string 205 in the storage device 13. Then, the control unit 51 displays “*” for the number of characters in the specific number string 205 on the specific number / character display unit 14 (see FIG. 11C, step S5).

Steps P6 to P9 and steps R2 to R4 are the same as the operation of the second embodiment of the present invention, and are therefore omitted. However, when it is detected that the button pressure detection frequency 202 in step R4 is within the specified range (in the case of Yes in step R4), the branch destination is not step R5 but step B5.

  The control unit 51 branching to step B5 refers to the position 1 sensor display number to the position 10 sensor display number 203 (see FIG. 6) stored in the storage device 13, and displays it at the key position of the notified key position data. It is checked whether or not the number being matched matches the number at the beginning of the specific number string 205 stored in the storage device 13 (step B5). If the control unit 51 detects that these numbers do not match (No in Step B5), it branches to Step P9. If the control unit 51 detects that these numbers match (Yes in step B5), it branches to step S11.

  The control unit 51 branched to step S11 deletes the first number of the specific number string 205 stored in the storage device 13, and shifts the remaining number toward the beginning (see (b) of FIG. 11). Then, the control unit 51 displays “*” for the number of characters in the specific number string 205 on the specific number / character display unit 14 (see step S11 in FIG. 11D).

  Subsequently, the control unit 51 checks whether or not the specific number string 205 stored in the storage device 13 has become empty (step B6). When the control unit 51 detects that the specific number string 205 is not empty (No in Step B6), the control unit 51 branches to Step P9. When the control unit 51 detects that the specific number string 205 is empty (Yes in step B6), the control unit 51 branches to step P12.

  Steps P12 to P13 are the same as the operation of the second embodiment of the present invention, and are therefore omitted.

  Note that the read-only storage device 61 of the present embodiment is replaced with the card described in the second embodiment of the present invention, and the control unit 51 uses the card reader unit 18 to read a specific character string from the card. You may do it. The registration of the specific character string to the card is a technique well known to those skilled in the art, and a description thereof is omitted here.

  The read-only storage device 61 of this embodiment is replaced with a network connection unit (not shown), and the control unit 51 uses this network connection unit to read a specific character string from a server (not shown). Also good. Note that means for storing information such as a specific character string in the server and means for reading out the information from the server are techniques well known to those skilled in the art and will not be described here.

  Note that the read-only storage device 61 of this embodiment may be replaced with a non-volatile storage device capable of writing and reading. An example of registering a specific character string in the nonvolatile storage device will be described in a fourth embodiment of the present invention described later.

  In this embodiment, “*” corresponding to the number of characters in the specific number string 205 is displayed on the specific number / character display unit 14. However, as in the second embodiment of the present invention, The character string itself may be displayed.

  According to the third embodiment of the present invention, the input character string is the specific numeric string 205 stored in advance in the read-only storage device 61, and the specific number / character display unit 14 includes the number of characters of the specific numeric string 205. By displaying “*” for the minute, the security function can be enhanced by using the specific number string 205 as a personal identification number.

  Further, according to the third embodiment of the present invention, the character string to be input is the specific numeric string 205 stored in the read-only storage device 61 in advance, and the number familiar to the operator as the specific numeric string 205. By adopting, it is possible to reduce the burden on the operator. On the other hand, since the arrangement of numbers displayed on the variable number display / input unit 16 is changed randomly, even if the numbers stored in the read-only storage device 61 are familiar to the operator, Moreover, even if the same numbers are continuous, there is an effect that normal input by a person who is in a state of drunkenness, a person who is poorly sleep, or an infant is not easy.

  Further, according to the third embodiment of the present invention, the specific character string is read from the card or the writable / readable non-volatile storage device, and the user can easily change the specific character string stored therein. As a result, the degree of freedom of use is increased as compared with the case where the specific character string is read from the read-only storage device 61.

  Next, a fourth embodiment of the present invention will be described in detail with reference to the drawings. Note that in the description of the fourth embodiment, parts that are the same as those in the second embodiment and have already been described are redundant, and are therefore omitted to the extent that the flow of description is not obscured.

And the control part 81 branches to step Q1, when it detects that the alarm switch part 88 is an OFF state (in the case of No of step J1). When the control unit 81 detects that the alarm switch unit 88 is in the ON state (Yes in step J1), the control unit 81 branches to step J2.

  The control unit 81 branched to step J2 checks whether or not the alarm time 206 and the specific number string 207 are set (step J2). And the control part 81 branches to step Q1, when it detects that the alarm time 206 and the specific number string 207 are not set (in the case of No of step J2). When the control unit 81 detects that the alarm time 206 and the specific numeral string 207 are set (Yes in step J2), the control unit 81 branches to step J3.

  The control unit 81 branched to step J3 checks whether or not the time of the clock unit 80 is between the alarm time 206 and the time obtained by adding the countdown time 201 to the alarm time 206 (step J3). For example, if the alarm time 206 is “6:30:30” and the countdown time 201 is “10 seconds”, the time of the clock unit 80 is “6:30:30” and “6:30” Check if it is between “10 minutes”. When the control unit 81 detects that the time of the clock unit 80 is not between the alarm time 206 and the time obtained by adding the countdown time 201 to the alarm time 206 (in the case of No in step J3), the control unit 81 performs step Q1.
