[D] Description of Incoming Transaction History Display Function The flowchart shown in FIG. 11 (steps S31 to S3)
The incoming transaction history display function (second function) of the IC card processing device 10 of the present embodiment will be described with reference to 5) and FIGS. In the incoming transaction history display function (step S5) which is the second function of the present embodiment,
At step S23 (S4), the deposit log information (transaction history) for the balance information displayed on the display unit 11 when the select key 18a is pressed is changed to I at step S2 in FIG.
If the information is included in the information acquired from the C card 20 (YES route of step S31), the first information in the payment log information, that is, the first payment transaction information is displayed on the display unit 11 as an initial display. (Step S32). If the payment log information does not exist (NO route of step S31), the following function, a transaction history display function (step S31)
Go to 7). FIG. 7 does not show the process of determining whether or not there is payment log information in step S31.

In the case where a plurality of electronic money (currency) deposit logs are stored in the memory 21 of the IC card 20 as the deposit log information, for example, as shown in FIG. The first deposit log for the currency displayed on the display unit 11 when the function is selected is displayed on the display unit 11 as an initial display.

For example, the second display “JP” in FIG.
When the select key 18a is pressed while performing "50,000", the first deposit log for Japanese yen, in this case, the log information in the first record (No. 00) of the log file is displayed in FIG. Is displayed on the display unit 11. That is, the display unit 11 displays “CR” (Credit Record) indicating that the transaction type is a deposit transaction, a history number “1”, and a deposit amount ( “Transaction value” “500” is displayed as the initial display (second display) of the incoming transaction history display function, and the transaction type, history number and deposit amount and the transaction date and time “AM10 97-02” -10 "are alternately displayed on the display unit 11 at fixed time intervals.

During such initial display, select key 1
When the button 8a is pressed ("select" route in step S33 (S6)), as described above with reference to FIG. 7, the process proceeds to the next function, a transaction history display function (step S7). During the initial display, the shift key 18b is pressed (step S
If the next payment log information is present (YES route in step S34), the next payment log information is displayed (step S35), and the process returns to step S33 to repeat the same processing. .

When the last deposit log information is displayed (NO route in step S34), the process returns to step S34.
Returning to 32, the first payment log information is displayed.
During the display of each deposit log information, the select key 18a is displayed.
Is pressed ("select" route in step S33 (S6)), the transaction history display function (step S33) is immediately performed.
Go to 7).

Therefore, when the deposit log information as shown in FIG. 12A is stored in the memory 21 of the IC card 20, as shown in FIG. 12B, “CR 1500” and “AM1097- 02-10 "alternately, every time the shift key 18b is pressed," CR 2
The second that displays "200" and "--------" alternately
Is switched to the third display state in which "CR3800" and "PM03 97-01-10" are alternately displayed. When the shift key 18b is pressed three times, the display state returns to the first display state again.

When the transaction date and time are not recorded (“00.00.00.00” in FIG. 12A), the display unit 1
In FIG. 12, the transaction date and time is "----, as shown in FIG.
---- ". In addition, as shown in FIG. 12B, when two or more payment log information are sequentially switched and displayed, the payment log information is the latest (or oldest). The objects are displayed on the display unit 11 in chronological order.

As described above, in the incoming transaction history display function, by pressing the shift key 18b, the display content on the display unit 11 can be changed, and a plurality of incoming log information can be sequentially and cyclically displayed. . When displaying the transaction date and time, the content to be displayed (here, the type of currency)
The arrangement and display contents of the transaction date and time are changed according to.

For example, in the United States, the date, month, and year are generally described in the order of day-month-year. Therefore, when the balance of US dollars is displayed by the numerical value (balance) information display function, the select key 18a is pressed to enter the transaction. When the history display function is selected (when the payment log information on the US dollar balance is displayed), the display order of the transaction date and time is switched as shown in FIG.

In Japan, the date, month, and day are generally described in the order of year-month-day. Therefore, when displaying the deposit log information on the balance of Japanese yen, the order shown in FIG. The date of the street is displayed. In this way, American-style dates are displayed for those who use the US dollar as their primary currency, and Japanese-style dates for those who use the Japanese yen as their primary currency. Is performed, and an optimal date display according to the holder of the IC card 20 can be realized.

Further, as shown in FIG. 14, for example, there are n pieces of deposit log information. After the shift key 18b is pressed, the n-th (last) deposit log information is displayed on the display section 11, and then the deposit log information is displayed. The final history display information “END” indicating that all are displayed is displayed on the display unit 11. As a result, it is possible to clearly notify the information viewer that all the payment log information has been displayed.

[E] Explanation of Departure Transaction History Display Function The flowchart shown in FIG. 15 (steps S41 to S4)
With reference to 5) and FIG. 16, a description is given of the transaction history display function (third function) in the IC card processing device 10 of the present embodiment.

The third function of the present embodiment, the outgoing transaction history display function (step S7), is performed in substantially the same manner as the above-mentioned incoming transaction history display function, as described below. The difference is that as shown in FIG. 16, the transaction type displayed on the display unit 11 is “DR” (Debit
Record).

In the transaction history display function, step S23 is also performed.
When the select key 18a is pressed in (S4), the display unit 1
The withdrawal log information (transaction history) for the balance information displayed in 1 is stored in the IC card 20 in step S2 in FIG.
(Step S41)
YES route), the first information in the withdrawal log information, that is, the first withdrawal transaction information is set as the initial display and the display unit 1
1 (step S42).

At this time, as the withdrawal transaction information, FIG.
As shown in FIG. 11, the transaction type (DR), the history number, the withdrawal amount, and the transaction date and time are alternately displayed at regular intervals.
Will be displayed. If there is no withdrawal log information (NO route in step S41), the process proceeds to the next function, a card status display / change function (step S9). FIG.
Here, the illustration of the processing for determining the presence / absence of withdrawal log information in step S41 is omitted.

When a plurality of withdrawal logs of electronic money (currencies) are stored in the memory 21 of the IC card 20 as withdrawal log information, the display unit 11 displays the information when the deposit transaction history display function is selected. The first withdrawal log for the displayed currency is displayed on the display unit 11 as an initial display. If the select key 18a is depressed during the initial display ("select" route of step S43 (S8)), as described above with reference to FIG. 7, the process proceeds to the card status display / change function (step S9). I do.

On the other hand, during the initial display, the shift key 18b is depressed (“shift” route in step S43), and if there is the next payout log information (YES route in step S44), the next payout log information is displayed. (Step S4)
5) Thereafter, the process returns to step S43 and the same processing is repeated.

When the last withdrawal log information is displayed (NO route of step S44), the process returns to step S44.
Returning to 42, the display of the first payment log information is performed.
Further, during display of each withdrawal log information, the select key 18a is displayed.
Is pressed ("select" route in step S43 (S8)), the process immediately proceeds to the card status display / change function (step S9).

Therefore, as shown in FIG. 14, for example, when there are n pieces of withdrawal log information, each time the shift key 18b is pressed, the transaction type (DR), the history number, the withdrawal amount, and the transaction amount are sequentially displayed. The date and time are alternately displayed, and after displaying the nth (last) withdrawal log information on the display unit 11, the final history display information "END" indicating that all the withdrawal log information has been displayed is displayed. After displaying on the part 11, the first
Return to the display state of.

[0086] As in the case of the incoming transaction history display function,
If the transaction date and time are not recorded, the display unit 11
The transaction date and time is "--------" as shown in FIG.
Will be displayed as When two or more payout log information are sequentially switched and displayed, the payout log information is displayed on the display unit 11 in chronological order from the latest (or oldest).

As described above, also in the transaction history display function, by pressing the shift key 18b, the display content on the display unit 11 can be changed, and a plurality of withdrawal log information can be sequentially and cyclically displayed. it can. Also, as with the transaction history display function, when displaying the transaction date and time, the arrangement and display contents of the transaction date and time are changed according to the content to be displayed (in this case, the type of currency).
The most suitable date and time display according to the holder can be realized.

[F] Description of Card Status Display / Change Function The flowchart shown in FIG. 17 (steps S51 to S6)
1), a flowchart shown in FIG.
S72) and the card status display / change function (fourth function) in the IC card processing device 10 of the present embodiment will be described with reference to FIGS.

In the card status display / change function (step S9) which is the fourth function of the present embodiment, the current card status is displayed on the display unit 11 as an initial display (step S51). The card status is confirmed by reading the card status from the IC card 20. There are three types of card states: locked, unlocked, and locked out, and display examples of the respective states on the display unit 11 are shown in FIGS. 19A to 19C.

The locked state is a state where the IC card 20 cannot be used at present, but can be changed to an unlocked state (usable state) by inputting / verifying a personal identification number. If
For example, as shown in FIG.
1 is displayed. The unlocked state is a state in which the IC card 20 can be used. When the card state is the unlocked state, for example, as shown in FIG.
LK ”is displayed on the display unit 11.

The lockout state is a state in which the use of the IC card 20 becomes impossible due to a wrong input of a personal identification number or an improper use, and this state cannot be changed / released except by a privileged person. When the card state is the lockout state, for example, as shown in FIG.
“LOUT” is displayed on the display unit 11.

If the card state is the lockout state (LOUT route in step S52), the I
The processing for the C card 20 is forcibly terminated (step S53). That is, since various information cannot be obtained from the memory 21 for the IC card 20 in the lockout state, the process shifts from step S1 in FIG. 7 to step S51 in FIG. 17 to indicate that the IC card 20 is in the lockout state. After “LOUT” is displayed on the display unit 11,
The MPU 12 ends the processing.

On the other hand, if the select key 18a is pressed while "LOCK" is being displayed while the card state is locked (LOCK route in step S52) [step S54 (S1
0) "select" route], as described above in FIG.
The process proceeds to the next function, that is, the password change function (step S11).

For example, as shown in FIG.
If the enter key 18c is pressed while "K" is displayed ("enter" route in step S54), the process proceeds to a process for changing the state of the IC card 20 from the locked state to the unlocked state (steps S55 to S57). In order to change the state of the IC card 20 from the locked state to the unlocked state, it is necessary to input a personal identification number stored in the card and perform verification, and in this embodiment, the personal identification number is used. Is realized by pressing two types of keys, the shift key 18b and the enter key 18c, as follows.

When the enter key 18c is depressed while "LOCK" is displayed, the password input mode (step S55; FIG. 18)
When the process proceeds to steps S62 to S72), first, the default value of the first digit is blinked (flashed) on the display unit 11 (step S62). When the shift key 18b is pressed in this state (“SHIFT” in step S63)
Route), the first digit is changed and blinked according to the depression of the shift key 18b (step S6).
4).

When the enter key 18c is pressed (the "enter" route in step S63), the enter key 1
The numerical value when 8c is pressed is displayed without blinking (step S65). In this state, when the shift key 18b is pressed (the "shift" route in step S66), the numerical display is blinked again (step S6).
7), the state returns to the state where the numerical value can be changed by pressing the shift key 18b. On the other hand, if the enter key 18c is pressed again after the blinking is stopped in step S65 (the "enter" route in step S66), the numerical value of the first digit is determined (step S68).

Thereafter, if the shift key 18b is pressed (the "shift" route in step S69), the default value of the next digit is blink-displayed (step S70), and the process returns to step S63. The processing of steps S63 to S70 is repeatedly executed until the numerical value of the last digit is determined. And
When the numerical value of the last digit is determined and the enter key 18c is pressed ("enter" route in step S69), the password is determined (the input of the password is completed; step S71).

As shown in FIG. 17, when canceling the password input during execution of the password input mode (step S55), the user presses the select key 18a (YES route in step S55 '). ), It is possible to return to the initial display state of this function (card state display; step S51) at any time.

When the password is determined in the password input mode as described above, a lock release request is transmitted to the IC card 20 together with the password (step S5).
6) Read the card status of the IC card 20 again,
Alternatively, after receiving a response (collation result) including the card status from the IC card 20 (step S5).
7) The process returns to step S51 to display the card status.

At this time, if the password is correct, the state is changed to the unlocked state, and the display of the card state on the display unit 11 is changed to "UNLK". If the password is incorrect, the state is unlocked. No change is made, and the display of the card status on the display unit 11 remains "LOCK" or "LOUT".

Here, the procedure for changing from the locked state to the unlocked state and the display state at that time will be specifically described with reference to FIG. 20. As shown in FIG. 20, the enter key 18c is displayed while "LOCK" is displayed. Is pressed to shift to the password input mode, "PC =" is displayed on the display unit 11, and at the same time, the default value "1" is blink-displayed in the first digit. When the shift key 18b is pressed, the first digit is incremented by one (1 → 2 →... → 9 → 0 →).
…), When the enter key 18c is pressed at the time of confirmation, the blink is stopped.

For example, when the enter key 18c is pressed while "5" is displayed without blinking in the first digit,
The numerical value of the digit is determined to be "5", and the first digit is masked and displayed by "-". When the shift key 18b is pressed in a state where "5" is displayed without blinking in the first digit, "5" is blinked again, and a state in which the numerical value can be changed by the shift key 18b is enabled.

Similarly, from the second digit onward, the last digit (FIG. 20)
(5 digits), and when the input of the personal identification number is completed, the enter key 18c is pressed. If the password is correct, the IC card 20 is changed from the locked state to the unlocked state, and the display of the card state on the display unit 11 switches from "LOCK" to "UNLK".

When the current card state is unlocked (UNLK route in step S52) and the select key 18a is pressed while "UNLK" is displayed [step S52].
58 (S10) "select" route], as described above with reference to FIG. 7, the flow proceeds to the next function, that is, the password change function (step S11).

For example, as shown in FIG.
If the enter key 18c is pressed while "K" is displayed ("enter" route in step S58), the process proceeds to a process for changing the state of the IC card 20 from the unlocked state to the locked state (steps S59 to S61). .

When changing the state of the IC card 20 from the unlocked state to the locked state, it is not necessary to input / verify the personal identification number. First, a display “LK” for confirming whether or not to make a transition to the locked state is required. Is performed, and the enter key 18c is pressed according to the display (“Enter” in step S60).
(Route), after the IC card 20 is shifted to the locked state (step S61), the process returns to step S51. At this time, the card status display on the display unit 11 changes from “UNLK” to “LOK”.
CK ”.

Shift key 18 in response to confirmation display "LK?"
When the b or the select key 18a is pressed (the "shift" route in step S60), the process of changing the state of the IC card 20 from the unlocked state to the locked state is canceled, and the initial display state of this function (card State display; return to step S51).

As described above, according to the IC card processing apparatus 10 of the present embodiment, the state of the IC card 20 can be changed while inputting the password using the three types of keys 18a to 18c. . That is, the state of the IC card 20 stored as the protection data protected from external access in the memory 21 of the IC card 20 is usually changed by the three keys 18a to 18 as described above.
By operating c, the state of the IC card 20 can be displayed on the display unit 11 and the state can be changed from locked to unlocked, which is convenient for the holder of the IC card 20. Is greatly improved.

[G] Description of PIN Change Function The flowchart shown in FIG. 22 (steps S81 to S8)
With reference to 9) and FIG. 23, the password change function (fifth function) in the IC card processing device 10 of the present embodiment will be described. In the present embodiment, the password registered in the IC card 20 can be changed as follows by using the password input mode described with reference to FIG.

In the personal identification number changing function (step S11), which is the fifth function of the present embodiment, "PC" is displayed on the display unit 11 as an initial display as shown in FIG. 23 (step S81). If the select key 18a is depressed during such initial display, a message [Step S82 (S1

The processing shifts to the next function of writing / displaying / changing personal information (step S13).

When the enter key 18c is depressed during the initial display ("enter" route in step S82), the current password is input (step S83; current password input mode). In the present password input mode, FIG.
"OLD" is displayed on the display unit 11 as shown in FIG. The input of the current personal identification number in step S83 is performed in the same procedure as in the personal identification number input mode described above with reference to FIG. When canceling the input of the personal identification number during the input of the current personal identification number, the user can depress the select key 18a (YES route in step S83 ') at any time to display the initial display state of this function (“PC” display; It is possible to return to step S81).

After inputting the current password, the flow shifts to a new password input mode for inputting a new password [step S8].
4: New PIN input mode (first time)]. In the new password input mode (first time), “NEW1” is displayed on the display unit 11 as shown in FIG. The input of the new password in step S84 is also performed in the same procedure as in the password input mode described above with reference to FIG. In order to cancel the password input during the input of the new password, the user can depress the select key 18a (YES route in step S84 ') at any time to display the initial display state of this function (“PC” display; It is possible to return to step S81).

After a new password is input once, in the present embodiment, the new password input in step S84 is input again for confirmation [step S85;
New PIN input mode (second time)]. In the new password input mode (second time), “NEW2” is displayed on the display unit 11 as shown in FIG. The input of the new password in step S85 is also performed in the same procedure as in the password input mode described above with reference to FIG. In order to cancel the input of the personal identification number during the re-input of the new personal identification number, the user can depress the select key 18a (YES route of step S85 ') at any time to display the initial display state of this function (“PC”). Display; it is possible to return to step S81).

As described above, after the current password and the new password are input twice, the enter key 18
By pressing c, the current password and the new password entered twice are transmitted to the IC card 20 together with the request for changing the password (step S86), and the collation / confirmation of the current password and the confirmation / registration of the new password are performed. This is performed by the IC card 20.

The MPU 12 waits for a response from the IC card 20, and when there is a response (YES route in step S87), displays the result of changing the personal identification number on the display unit 11 (step S88). When the personal identification number is changed in the IC card 20, as shown in FIG.
"OK" is displayed, and the operator who has changed the personal identification number (the holder of the IC card 20, etc.) confirms this and presses the select key 18a (YES in step S89).
Route), and returns to the initial display state of this function (“PC” display; step S81).

As described above, according to the IC card processing apparatus 10 of the present embodiment, the password is input using the three types of keys 18a to 18c while the IC card 20 is input.
Can be changed. [H] Description of Personal Information Write / Display / Change Function (Memo Function) A flowchart shown in FIG. 24 (steps S91 to S10)
1), a personal information writing / display / change function (sixth function; memo function) in the IC card processing device 10 of the present embodiment will be described with reference to FIGS.

In the personal information writing / display / change function (step S13), which is the sixth function of the present embodiment, as shown in FIGS. 25 and 26, for example, a first memo (“MEM1”) is used as an initial display. ; Personal information) is displayed on the display unit 11 (step S91). At this time, if no writing has been performed yet on the first memo, a default value is displayed.

During such initial display, select key 1
When the button 8a is depressed ["select" route in step S92 (S14)], as described above in FIG.
Also, during the initial display, the shift key 18b is pressed (the "shift" route in step S82), and if there is a next memo (YES route in step S93), the next memo is displayed (step S94), and the process proceeds to step S92. Returning, the same processing is repeated. Note that a default value is also displayed for the second and subsequent memos when no writing has been performed yet.

When the last memo is displayed (step S9)
3 NO route), and returns to step S91 again to
The memo is displayed. Also, if the select key 18a is pressed while each memo is displayed [Step S92 (S
14) "Select" route], and immediately proceed to the clock display setting function (step S15).

Therefore, for example, as shown in FIG. 25, when there are n memos (“MEM1” to “MEMn”; personal information),
Each time the shift key 18b is pressed, the display of the memo is sequentially switched, and after the n-th (last) memo is displayed on the display unit 11, the display returns to the first memo display state.

As described above, in the personal information writing / display / change function, by pressing the shift key 18b, the display content on the display unit 11 is changed, and a plurality of personal information (memos) is displayed.
Can be displayed sequentially and cyclically. On the other hand, when the enter key 18c is pressed while the memo (personal information) is being displayed (the "enter" route in step S92), the personal information is written / changed for the memo, and the display unit 11 displays the first digit of the memo. The value is blink-displayed (step S95). In this state, the shift key 18
When b is pressed (the "Shift" route in step S96), the numerical value of the first digit is changed according to the pressing of the shift key 18b and blinking is displayed (step S97).

When the enter key 18c is pressed (the "enter" route in step S96), the enter key 1 is pressed.
The numerical value when 8c is pressed is determined as the value of the first digit (step S98). Thereafter, if the shift key 18b is pressed (the "shift" route in step S99), the value of the next digit is blink-displayed (step S100), and step S9 is performed.

[I] Description of Clock Display Setting Function The flowchart shown in FIG. 27 (steps S111 to S1)
17) and FIG. 28, the IC of the present embodiment will be described.
12 is a flowchart for explaining a clock display setting function (seventh function) in the card processing device 10.

As described above, the clock display setting function (step S15), which is the seventh function of the present embodiment, is executed when the IC card 20 is inserted into the IC card processing device 10 and the IC card 20 is not inserted. Sometimes IC card processing device 1
0 is a function for setting whether or not to display a clock on the display unit 11 of the “0”. When this clock display setting function is selected,
As the initial display, the current clock display setting state (for example,
“Pon”: clock display valid, “Poff”: clock display invalid) is displayed on the display unit 11 (step S111).

During such initial display, select key 1
When the button 8a is pressed (“select” route in step S112 (S16)), as described above in FIG.
The process returns to the first function (numerical value (balance) information display function (step S3)). If the enter key 18c is pressed during the initial display ("enter" route in step S112), the setting change mode is set, the current setting state is blinked (step S113), and the shift key 18b is pressed in this state. If it is on (YES route of step S114), it is changed to off if it is on, and it is changed to on if it is off (step S115).

Then, by pressing the enter key 18c (YES route in step S116), the setting state is determined, and the clock display setting state ("Pon" or "Poff") is displayed without blinking (step S116).
117), returning to step S112. The changed clock display setting state is registered in the clock display setting register 26 attached to the MPU 12. In this register 26,
The flag is set when the clock display is enabled.

Here, the procedure for changing the clock display setting state from valid to invalid and the display state at that time will be specifically described with reference to FIG. 28. As shown in FIG. 28, the current setting state “Pon Is displayed during the initial display.
By pressing the enter key 18c, "on" blinks, and then, by pressing the shift key 18b, "on" is changed to "off". When the enter key 18c is pressed, "Poff" is displayed in a state where the blink is stopped, and the stop of the clock function (low power consumption mode) when the card is not inserted is determined. As mentioned above,
According to the IC card processing device 10 of the present embodiment, the clock display setting state can be changed using the three types of keys 18a to 18c.

[J] Description of display time shortening method By the way, in the IC card processing apparatus 10 of the present embodiment,
To display the first information (the first balance information of the default pocket in the present embodiment) on the display unit 11 more quickly when the IC card 20 is inserted, the IC card processing device 10
When the C card 20 is inserted, the MPU 12 starts reading data from the memory 21 of the IC card 20, completes reading of the first balance information in the default pocket, and simultaneously displays the first balance information on the display unit 11 , And the subsequent data is read continuously after the display, and the other functions are sequentially enabled after the reading is completed.

In the present embodiment, FIGS.
The determination register 25 as shown in FIG.
2, each key 1 when selecting a function
The timing at which the pressing operations of 8a to 18c become effective is M
The PU 12 can easily make the determination. That is, as described above, the MPU 12 sets the read completion flag for the data that has been read from the memory 21 of the IC card 20 for each read information unit.

More specifically, as shown in FIG. 29 (a), the judgment register 25 of the present embodiment sets the input log so that the read completion flag can be set for each of the pocket Nos. 00 to ll storing the balance information. Record No. 00 that stores information
~ Mm so that the read flag can be set for each of the records No. 00 to nn which store the output log information, and
The configuration is such that a read flag for the card state of the IC card 20 can be set.

The MPU 12 starts reading data from the IC card 20, and as shown in FIG. 29B, when only the read flag for the pocket No. 00 in the balance information is set, the pocket No. 00 Is displayed on the display unit 11, the select key 18a and the shift key 18b.
The enter key 18c does not function even if it is pressed.

Then, data reading by the MPU 12 proceeds, and, for example, as shown in FIG.
When the input log information is read, the numerical value (balance) information display function, which is the first function, is effective, and all the balance information can be displayed. Can be displayed by the operation of. However, the display of outgoing log information and card status cannot be performed yet.

Next, referring to the flowchart (steps S121 to S127) shown in FIG. 30, the data reading control and the display control performed by the IC card processing device 10 (MPU 12) using the above-described determination register 25 will be described. A brief description will be given. As shown in FIG.
When the C card 20 is inserted into the IC card processing device 10 (step S121), first, the MPU 12 registers the registers 25 to 27, the ROM 14,
After diagnosing the RAM 15 and the like (step S12)
2), a directory in the memory 21 of the IC card 20 is selected (step S123).

Then, the MPU 12 reads the balance information of the default pocket No. 00 from the memory 21 of the IC card 20 (step S124), sets the read flag of the pocket No. 00 in the determination register 25, and sets the pocket No. 00 balance information (eg “US $ 1000.0
0 ") is displayed on the display unit 11. Subsequently, the MPU 12
Reads the balance information of the remaining pockets, and sets a read flag in the determination register 25 each time the balance information of each pocket is read (step S125). Each time the balance information of each pocket is read, the display can be switched by the shift key 18b.

Similarly, log information (transaction history information)
Is read, and a read flag is set in the determination register 25 each time the log information of each record is read (step S
126). That is, the first record of the incoming log information (record No. 0
At the point when (0) is read, the first press operation of the select key 18a becomes effective, and by pressing the select key 18a, the first entry log information is displayed as an initial screen of the entry transaction history display function. Thereafter, each time one piece of incoming log information is read, the operation of pressing the shift key 18b becomes effective. When the first log (record No. 00) of the output log information is read, select key 1
The second pressing operation of 8a becomes effective, and by pressing the second pressing operation, the first outgoing log information is displayed as an initial screen of the outgoing transaction history display function. Thereafter, each time one log is read, the operation of pressing the shift key 18b becomes effective.

When reading the card state (lock, unlock or lockout) of the IC card 20 (step S127), the MPU 12 sets a read flag in the determination register 25. At this point, the state display function by the pressing operation of the select key 18a becomes effective.

As described above, according to the IC card processing apparatus 10 of the present embodiment, by using the determination register 25, the MPU 12 determines the timing at which the pressing operation of each of the keys 18a to 18c at the time of selecting a function becomes valid. The IC card 20 can be easily determined and the IC card 20
It is possible to greatly reduce the time from the insertion into 0 to the display on the display unit 11.

[K] Description of Function when Card Is Not Inserted In the IC card processing apparatus 10 of the present embodiment, the MPU 12 operates the key 18 with the IC card 20 mounted.
While the seven functions described above are performed in response to the pressing operations of a to 18c, when the IC card 20 is not inserted, the display unit 11 is used to perform a unique function.

In this embodiment, FIG. 5 (a) and FIG.
As shown in FIG. 5B, a card detection switch 19a (also used as the power supply switch 31) for detecting insertion / non-insertion of the IC card 20 is provided, and FIG.
As shown in (1), when no card is inserted, the MPU 12 realizes a unique function. The functions when the card is not inserted include the clock display function and the memo function described above.

These functions can be realized by keeping the power supply to the MPU 12 in the power supply state at all times. In the present embodiment, by setting a flag in the relay control register 27, the relay switch 32 is turned on (closed) when a card is not inserted. Therefore, the MPU 12 can always detect the pressing of the keys 18a to 18c in an operable state, and can realize various functions by pressing the keys 18a to 18c. If you do not consider low power consumption,
The relay switch 32 and the power supply switch 31 (card detection switch 19a) are omitted, and the battery 30 and the MPU 12
It may be configured to always supply power to the power supply.

In this embodiment, the clock display validity setting is performed according to the procedure described above with reference to FIG. 27, and when the flag is set in the statistical display setting register 26, the clock display function is executed. In the memo function, MPU12
When the keys 18a to 18c are pressed, the memo information is stored in the RAM.
15 (memo information storage unit) and the RA
The memo information stored in M15 is displayed on the display unit 11. This memo function can easily perform memo display / setting in the same manner as in the examples shown in FIGS. 25 and 26 by performing the operation described above with reference to FIG.

When the clock display function is valid, the clock display function and the memo function can be selected by pressing the select key 18a, almost in the same manner as in the example shown in FIG. That is, as shown in FIG.
Pressing the select key 18a in the clock display state switches to the memo display mode, and pressing the select key 18a in the memo display state switches to the clock display state.

When the enter key 18c is pressed while the clock is displayed, the mode shifts to the time adjustment mode. (Changeable state). The parameters displayed during blinking are cyclically changed by pressing the shift key 18b, and are set by pressing the enter key 18c, and the next parameter is blink-displayed.

Referring to FIG. 32, the procedure for changing the minute display of the time from "15" to "40" and the display state at that time will be described in detail. As shown in FIG. 18c, the mode shifts to the adjustment mode. First, the first parameter (day of the week "SUN
") Is blinked. Since the day of the week display is not changed, the enter key 18c is pressed.

As a result, the second parameter (time “1”
0 ”) is blinked, but since the time display is not changed, the enter key 18c is pressed to blink the third parameter (minute“ 15 ”). In this state, the shift key 18b is pressed. The minute display “15” is changed to “4”.
0 ”. Then, the enter key 18c is pressed,
The fourth parameter (second “30”) is blinked, but since this second display is not changed, the select key 18a is displayed.
By pressing, the setting is completed and the display is switched to the clock display state.

In the clock display function, the MPU 12 controls the time to be automatically displayed on the display unit 11 only during a display period that is arbitrarily set in advance. It is also possible to control so that the time is temporarily displayed on the display unit 11 only when one of the buttons is pressed. Specifically, the time is always displayed only during the daytime, and the time is displayed only by pressing a key during the nighttime when the frequency of use is low. As described above, according to the IC card processing device 10 of the present embodiment, various functions can be realized using the display unit 11, the MPU 12, the RAM 15, the keys 18a to 18c, and the like even when the card is not mounted. Functionalization can be realized.

[L] Description of Low Power Consumption Mode In the IC card processing device 10 of the present embodiment, when the IC card 20 is not mounted, the power supplied from the battery 30 to the communication unit 16, the display unit 11, and the MPU 12 Is shifted to a low power consumption mode for saving power.

Examples of the low power consumption mode include a case where the above-described function is executed when a card is not inserted (when power is supplied even when the card is not inserted) and a case where the above-described function is not executed when a card is not inserted (when power is not inserted). There is a method of specifying whether power is supplied or not.

In this embodiment, as shown in FIG. 4A, the relay switch 32 that is turned on / off by the program (software) via the relay control register 27 is connected to the power supply switch 31 (card detection). Switch 1
9a) and the battery 3 when no card is inserted.
Whether or not to supply power to the MPU 12 from 0 can be arbitrarily set.

To enable the function when the card is not inserted, the flag for the relay switch 32 is set in the relay control register 27, so that even if the IC card 20 is not inserted, the flag shown in FIG. ), The relay switch 32 is turned on, and the battery 30
Power is supplied to U12. Fig. 3
The change to the state shown in FIG. 3B or FIG. 33C can be made by a program instruction or the like.

To invalidate the function when the card is not inserted, the flag for the relay switch 32 is not set in the relay control register 27, and the relay switch 32 is always turned off. In this case, if the IC card 20 is not inserted, the power supply switch 31 (card detection switch 19a) and the relay switch 32 are both off as shown in FIG. However, the IC card processing device 10 becomes inactive. It is impossible to change from such a state to the state shown in FIG.

When the IC card 20 is inserted in the state shown in FIG. 33 (b), the power supply switch 31 (card detection switch 19a) is turned on, and power is supplied from the battery 30 to the MPU 12, as described above. IC card 2
0 (the first to seventh functions) can be performed. The change from such a state to the state shown in FIG. 33A can be made by a program instruction or the like.

As described above, the card detection switch 19a
By combining the (power supply switch 31) and the relay switch 32, it is possible to easily change whether or not to enable the function when no card is inserted, and to disable the function when no card is inserted. MPU always
Since there is no power supply to the battery 12, the life of the battery 30 can be extended.

In the low power consumption mode, when the same information is continuously displayed on the display unit 11 for a certain period of time regardless of whether a card is inserted or not, the MPU 12 automatically displays the same information. There is also an erasing method. As another low power consumption mode, there is a method of stopping power supply to the communication unit 16, stopping power supply to the display unit 11, and clocking down the MPU 12 when a card is not inserted.

When the card is not inserted, the communication section 16 does not need to perform any communication.
Stopping the power supply to the power supply is effective for realizing low power consumption. Therefore, in the present embodiment, FIG.
As shown in (b), by supplying power to the communication unit 16 through the power supply switch 31, power can be supplied to the communication unit 16 when a card is inserted, while the communication unit 16 is not inserted when a card is not inserted. And the battery 30 to shut off the power supply.

In addition, when there is no need to perform display on the display unit 11, stopping power supply to the display unit 11 is effective for realizing low power consumption.
Therefore, in the present embodiment, as shown in FIG. 4C, by supplying power to the display unit 11 through the display unit power supply instruction switch 33, the display unit can be programmed (software). It is possible to arbitrarily set whether or not the power supply to the power supply 11 is stopped.

Furthermore, when the card is not inserted, there is no need to perform communication with the IC card 20, so that the MPU 12 can be operated with a low-frequency clock to reduce power consumption. At this time, since the processing speed is not given priority in the memo function when the card is not inserted (main processing is reading / writing to / from the RAM 15), there is no problem that the processing speed is slightly reduced.

Therefore, in the present embodiment, as described above with reference to FIG. 6, the clock supply system 13 for the MPU 12
It comprises a high-frequency clock oscillator 13a and a low-frequency clock oscillator 13b, and a switching circuit 13c which is switched by hardware depending on whether or not a program or IC card 20 is inserted. That is, when a card is inserted or when specified by a program, a clock from the oscillator 13a that oscillates a high-frequency clock is selected and output to the MPU 12, while when a card is not inserted or when specified by a program. , Selects a clock from the oscillator 13 b that oscillates a low-frequency clock, and outputs it to the MPU 12. Thus, when the card is not inserted, or when the card is inserted, and when specified by a program (for example, when the communication unit 16 is not used), the clock is reduced and the power consumption is reduced, that is, the life of the battery 30 is reduced. Can be extended.
