FIG. 5 is a flowchart for explaining the processing executed by the control circuit 6. When the power switch 25 is turned on, the control circuit 6 operates the card insertion ports 4 and 5.
Communication with the IC card 3 inserted into one of the two. FIG.
In step S1 (hereinafter, "step" is omitted), it is checked whether the first card detection sensor 26 is turned on. When the IC card 3 is inserted into the card insertion slot 4 and the leading end of the IC card 3 reaches below the first card detection sensor 26, the first card detection sensor 26 receives the light reflected by the IC card 3 Switch on.

Therefore, when the first card detection sensor 26 is turned on in S1, the process proceeds to S2, and the processing mode executed last time is displayed on the display 2. When the operator can use the same processing mode as the last time, the IC card 3
Into the space 30 of the card R / W mechanism 28.
Then, when each terminal arranged on the lower surface side of the IC card 3 comes into contact with the R / W head 31 provided at the back of the space 30, writing of time data (information) or reading of time data (information) is performed. Be executed.

In the next S3, the second card detection sensor 2
Check if 7 is turned on. When there is no need to change the processing mode, the leading end of the IC card 3 reaches below the second card detection sensor 27, and the second card detection sensor 27 receives light reflected by the IC card 3 and turns on. Switch. Therefore, the card detection sensor 2
When both 6 and 27 are on, the process proceeds to S4, where the processing mode displayed on the display 2 is set, and the current time data (information) is set to I in the predetermined processing mode set in S5.
The data is stored in the EEPROM 18 of the C card 3. However, in S3, when it is desired to execute a processing mode other than the processing mode displayed on the display 2, the insertion operation is stopped in a state where the leading end of the IC card 3 is inserted into the card insertion slot 4.

In S3, when the insertion operation is stopped while the tip of the IC card 3 is inserted into the card insertion slot 4, the first card detection sensor 26 is turned on and the second card detection sensor 27 is turned off. Therefore, the process goes to S6 to check whether a predetermined time n seconds has elapsed in this state. In this state, the processing of S3 and S6 is repeated until the predetermined time n seconds elapses. When the predetermined time n seconds elapses, the process proceeds to S7, and the processing mode is sequentially changed. In this embodiment, for example, the processing mode stored in the IC card 3 is changed to any one of the entry time, exit time, early exit time, flex entry time, and overtime exit time.

In the next step S8, the changed processing mode is displayed on the display 2 to notify the operator. And the above S3
Return to If the first card detection sensor 26 is still on and the second card detection sensor 27 is off, S
3, the processing mode is sequentially updated by the number of times by repeating the processing of S6 to S8. When the processing mode is changed as described above and the desired processing mode is displayed on the display 2, the operator inserts the IC card 3 into the card insertion slot 4.
Insert it all the way to the back. As a result, the leading end of the IC card 3 reaches below the second card detection sensor 27, and the second card detection sensor 27 receives light reflected by the IC card 3 and is turned on.

Therefore, if both the card detection sensors 26 and 27 are ON in S3, the process proceeds to S4, where the changed processing mode is set, and then the current time data (information ) Is stored in the EEPROM 18 of the IC card 3. Next, in S9, IC
The current time data (information) is stored in the card 3 in a predetermined processing mode, and the display 2 indicates that the processing is completed. Subsequently, the process proceeds to S10, where it is checked whether the second card detection sensor 27 has been turned off. When the IC card 3 is pulled out from the card insertion slot 4, first, the second card detection sensor 27 is turned off, the process proceeds to S11, and the processing mode displayed on the display 2 is erased.

In S10, the second card detection sensor 2
If the switch 7 is on, the process proceeds to S12, in which "card eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. Then, in S13, it is checked whether the first card detection sensor 26 has been turned off. In this S13, the first card detection sensor 26
Is ON, the process proceeds to S14, where "Card Eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. In S13, the IC card 3
Is pulled out from the card insertion slot 4, the first card detection sensor 26 is turned off, and the current processing ends.

As described above, the processing mode can be sequentially changed by stopping the insertion operation of the IC card 3 halfway, so that the desired processing mode can be easily changed. In addition, since troublesome switch operations are not required, the number of switches does not need to be increased even when the number of processing modes is increased, and the processing mode changing operation can be simplified and speeded up.

In the above embodiment, the first card detection sensor 26 and the second card detection sensor 27 are provided on the ceiling of the space 30, but the invention is not limited to this. For example, the first card detection sensor 26 and the second The second card detection sensor 27 may be provided on the floor. Also, the first card detection sensor 2
6. The second card detection sensor 27 is configured to detect the insertion of the IC card 3 by receiving the reflected light,
However, the insertion of the IC card 3 may be detected by separating the light receiving unit and the light emitting unit and blocking the light from the light emitting unit.

FIG. 6 is a longitudinal sectional view showing a modification of the card R / W mechanism. The card R / W mechanism 28 is provided with a roller 32 that slides on the upper surface of the IC card 3 inserted through the card insertion slot 4 and rolls on the ceiling of a space 30 formed inside the housing 29. Have been. The surface of the roller 32 is formed of a material having a large friction coefficient such as rubber.

Therefore, when the IC card 3 is inserted or pulled out, the roller 32 rotates due to friction on the surface of the IC card 3, and rotates in the direction A when the card is inserted and in the direction B when the card is pulled out. Rotate.
A magnetic sensor 33 for detecting the rotation direction of the roller 32 is provided on the upper surface of the housing 29. The magnetic sensor 33 can determine the rotation direction of the roller 32 based on the time interval between detection pulses of a plurality of magnets (not shown) embedded in the roller 32.

FIG. 7 is a flowchart for explaining a first modification of the processing executed by the control circuit 6. In FIG. 7, S
At 21, when the IC card 3 is inserted into the card insertion slot 4 and the first card detection sensor 26 is turned on, S 2
Then, the process proceeds to step S2, and the processing mode executed last time is displayed on the display device 2.

The operator inserts the IC card 3 as far as possible into the space 30 of the card R / W mechanism 28 when the same processing mode as the previous time is sufficient. By this card insertion operation, the IC card 3 comes into sliding contact with the roller 32 provided inside the card R / W mechanism 28, and the roller 32 rotates in the A direction.
After that, each terminal arranged on the lower surface side of the IC card 3 comes into contact with the R / W head 31 of the card R / W mechanism 28, and time data is written or time data is read.

In the next step S23, it is checked whether or not the rotation of the roller 32 is detected by the magnetic sensor 33. If the rotation of the roller 32 is detected in S23, the process proceeds to S24.
To check whether the rotation direction of the roller 32 is normal in the direction A (card insertion direction). And roller 3
If the rotation direction of No. 2 is normal rotation in the A direction, the process proceeds to S25, and the processing mode displayed on the display 2 is set. However, if the rotation direction of the roller 32 is not the A direction in S24, it is determined that the IC card 3 has been pulled out and the operator has interrupted the storage operation, and the process returns to S21.

In the next step S26, it is checked whether or not the second card detection sensor 27 has been turned on. And
When the IC card 3 is inserted, the second card detection sensor 27
Is turned on and both the card detection sensors 26 and 27 are on, the process proceeds to S27, and the current time data (information) is stored in the EEPROM 18 of the IC card 3 in the predetermined processing mode set in S25.

However, in S23, when it is desired to execute a processing mode other than the processing mode displayed on the display 2, the insertion operation is stopped with the tip of the IC card 3 inserted into the card insertion slot 4. . At this time, since the tip of the IC card 3 has not reached the roller 32,
2 is not rotating. In the above S23, the roller 32
When the rotation of the IC card 3 is not detected, the insertion operation is stopped with the tip of the IC card 3 inserted into the card insertion slot 4, so that the first card detection sensor 26 is turned on and the magnetic sensor 33 is 32 rotation has not been detected. In this case, the process shifts to S28, and in this state, the predetermined time (n
Second) has elapsed.

The processes in S23 and S28 are repeated until a predetermined time (n seconds) elapses in this state. Before the predetermined time (n seconds) elapses, the IC card 3 is inserted and the roller 32 rotates, the above-described S24
Execute the following processing. However, if the predetermined time (n seconds) has elapsed, the process proceeds to S29, and the processing mode is sequentially changed. In the present embodiment, for example, the time stored in the IC card 3 is changed to any of the processing modes of entry time, exit time, early exit time, flex entry time, and overtime time.

In the next step S30, the changed processing mode is displayed on the display 2 to notify the operator. And the above S
Return to 23. If the first card detection sensor 26 is still on and the rotation of the roller 32 has not been detected, the process returns to S2.
3, the processing mode is sequentially updated by the number of times by repeating the processing of S28 to S30. When the processing mode is changed as described above and the desired processing mode is displayed on the display 2, the operator inserts the IC card 3 into the card insertion slot 4. Thus, the tip of the IC card 3 reaches below the second card detection sensor 27 while rotating the roller 32, and the second card detection sensor 27 receives light reflected by the IC card 3 and is turned on.

Therefore, if the card detection sensors 26 and 27 are both on in S26, the process proceeds to S27, where the changed processing mode is set, and then the current time data (information ) Is stored in the EEPROM 18 of the IC card 3. In S26, when the second card detection sensor 27 is off,
The flow shifts to S31, where it is checked whether the rotation direction of the roller 32 is reversed in the direction B (card removal direction). If the rotation direction of the roller 32 is reversed in the direction B, it is determined that the IC card 3 has been pulled out and the roller 32 has been reversed, and the process returns to S23. However, if the rotation direction of the roller 32 is not the B direction in S31, IC
It is determined that the card 3 has been inserted, and the process returns to S26 to execute the processing from S27.

In the next step S32, the current time data (information) is stored in the IC card 3 in a predetermined processing mode, and the display 2 indicates that the processing is completed. Then S3
Proceed to 3 to check whether the second card detection sensor 27 has been turned off. When the IC card 3 is pulled out from the card insertion slot 4, first, the second card detection sensor 2
7 is turned off, the process proceeds to S34, and the processing mode displayed on the display 2 is deleted.

In step S33, the second card detection sensor 2
When 7 is on, the process proceeds to S35, where "Card Eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. Then, in S36, it is checked whether the first card detection sensor 26 has been turned off. In this S36, the first card detection sensor 26
Is ON, the process proceeds to S37, where "Card Eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. In S36, the IC card 3
Is pulled out from the card insertion slot 4, the first card detection sensor 26 is turned off, and the current processing ends.

As described above, the processing mode can be sequentially changed by stopping the insertion operation of the IC card 3 in the middle, so that troublesome switch operation is unnecessary, and the desired processing mode can be easily changed. Can be. In addition, since the insertion state or the removal state of the IC card 3 can be confirmed by monitoring the rotation direction of the roller 32 rotated by the insertion operation or the removal operation of the IC card 3, erroneous operation of the processing mode change operation can be prevented. The desired processing mode can be easily set.

FIG. 8 is a flowchart for explaining a second modification of the processing executed by the control circuit 6. The configuration of Modification 2 is the same as that of Modification 1 described above, and a description thereof will not be repeated. In FIG. 8, in S41, the IC card 3
Is inserted into the card insertion slot 4 to turn on the first card detection sensor 26, the process proceeds to S42, and the processing mode executed last time is displayed on the display 2.

The operator inserts the IC card 3 as far as possible into the space 30 of the card R / W mechanism 28 when the same processing mode as the previous time is sufficient. By this card insertion operation, the IC card 3 comes into sliding contact with the roller 32 provided inside the card R / W mechanism 28, and the roller 32 rotates in the A direction.
After that, each terminal arranged on the lower surface side of the IC card 3 comes into contact with the R / W head 31 of the card R / W mechanism 28, and time data is written or time data is read.

In the next S43, it is checked whether or not the rotation of the roller 32 is detected by the magnetic sensor 33. If the rotation of the roller 32 is not detected in S43, the process proceeds to S4
Proceed to 4 to check whether a predetermined time n seconds has elapsed. If the predetermined time n seconds has not elapsed in S44,
Returning to step S43, it is checked whether the roller 32 has rotated. If the predetermined time n seconds has elapsed without detecting the rotation of the roller 32 in S44, the process proceeds to S45 to check whether the rotation direction of the roller 32 is normal in the direction A (card insertion direction). And roller 3
When the rotation direction of No. 2 is normal rotation in the A direction, the process proceeds to S46, and the processing mode displayed on the display 2 is set. However, if the rotation direction of the roller 32 is not the A direction in S45, it is determined that the IC card 3 has been pulled out and the operator has interrupted the storage operation, and the process returns to S41.

When the first card detection sensor 26 is turned on by the insertion of the IC card 3 and the magnetic sensor 33 detects the normal rotation of the roller 32 when a predetermined time n seconds has elapsed after that, the process proceeds to S47 and S46. The current time data (information) is stored in the EEPROM 18 of the IC card 3 in the predetermined processing mode set in the above. However, when it is desired to execute a processing mode other than the processing mode displayed on the display 2, the IC card 3 is inserted into the card R / W mechanism 28 until the leading end of the IC card 3 slides on the roller 32.

Therefore, in the above S43, the roller 32
When the rotation of the IC card 3 is detected, the state in which the leading end of the IC card 3 is inserted into the space 30 of the card R / W mechanism 28 and S
The process proceeds to 48, and it is checked whether or not a predetermined time n seconds has elapsed in this state. That is, the IC card 3
Is inserted into the space 30 of the card R / W mechanism 28 and the roller 32 continues to rotate for a predetermined time (n seconds), S
When the process of 49 is performed and the roller 32 does not rotate for a predetermined time (n seconds), the current time data (information) is stored in the IC card 3 in the set processing mode.

Therefore, the processing of S43 and S48 is repeated until the predetermined time (n seconds) elapses in S48, and the insertion operation of the IC card 3 is performed before the predetermined time (n seconds) elapses. 32 stops, the aforementioned S4
4 and subsequent processes are executed. However, if the predetermined time (n seconds) has elapsed in S48, the process proceeds to S49, and the processing mode is sequentially changed. In the present embodiment, for example, the time stored in the IC card 3 is changed to any of the processing modes of entry time, exit time, early exit time, flex entry time, and overtime time.

In the next step S50, the changed processing mode is displayed on the display 2 to notify the operator. And the above S
Return to 43. If the first card detection sensor 26 is still on and the rotation of the roller 32 is detected, the process returns to S4.
3. The processing mode is sequentially updated by the number of times by repeating the processing of S48 to S50. When the processing mode is changed as described above and the desired processing mode is displayed on the display 2, the operator inserts the IC card 3 into the card insertion slot 4 and stops it.

Therefore, when the card detection sensor 26 is ON and the roller 32 rotates forward in S45, the process proceeds to S46, where the changed processing mode is set, and the current processing mode is changed in S47. The time data (information) is stored in the EEPROM 18 of the IC card 3. When the process of S46 is completed, the process proceeds to S51, in which the current time data (information) is stored in the IC card 3 in a predetermined processing mode.
Is stored on the display 2 to indicate that the processing is completed.

In the next step S52, it is checked whether or not the rotation direction of the roller 32 is reversed in the direction B (card removal direction). When the rotation direction of the roller 32 is reverse to the direction B, the process proceeds to S53, and the processing mode displayed on the display 2 is deleted. If the rotation direction of the roller 32 is normal in the direction A in S52, the process proceeds to S54, in which "Card Eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. Then, in S55, it is checked whether the first card detection sensor 26 has been turned off.

In step S55, when the first card detection sensor 26 is turned off, it is determined that the IC card 3 has been pulled out from the card insertion slot 4, and the current processing ends. As described above, since the processing mode can be sequentially changed by rotating the roller 32 by the insertion operation of the IC card 3, a troublesome switch operation is unnecessary, and the processing mode can be easily changed to a desired processing mode. . In addition, when the rotation direction of the roller 32 is normal rotation, the time data (information) is stored in the IC card 3, and when the rotation direction of the roller 32 is reverse rotation, it is possible to start over or end the second operation. The card detection sensor 27 can be omitted, and a desired processing mode can be easily set by inserting or removing the IC card 3.

FIG. 9 is a flowchart for explaining a third modification of the processing executed by the control circuit 6. The configuration of Modification 3 is the same as that of Modification 1 described above, and a description thereof will not be repeated. In FIG. 9, in S61, the IC card 3
Is inserted into the card insertion slot 4 to turn on the first card detection sensor 26, the process proceeds to S62, and the processing mode executed last time is displayed on the display 2. When the same processing mode as the previous time is sufficient, the IC card 3 is
Is inserted all the way into the space 30.

In the next step S63, it is checked whether or not the first card detection sensor 26 has been turned on / off. When it is desired to change the processing mode, the IC card 3 is inserted and removed through the card slot 4. As a result, the first card detection sensor 26 turns on and off. If the first card detection sensor 26 does not perform the on / off operation in S63, the process proceeds to S64, and it is checked whether a predetermined time (n seconds) has elapsed.

If the first card detection sensor 26 does not turn on / off while the predetermined time (n seconds) elapses, S
Proceeding to 65, it is checked whether the second card detection sensor 27 has been turned on. When the second card detection sensor 27 is turned on due to the insertion of the IC card 3, the process proceeds to S66, and when the second card detection sensor 27 is turned off, the process returns to S64 and the predetermined time (n seconds) Check if has passed.

In S66, it is checked whether both the first and second card detection sensors 26 and 27 are off. If both the first and second card detection sensors 26 and 27 are off at S66, it is determined that the IC card 3 is pulled out and the operation is interrupted, and the process returns to S61. However, if both the first and second card detection sensors 26 and 27 are not off in S66, the IC card 3 is mounted on the card R / W mechanism 28,
Proceeding to 67, the current time data (information) is stored in the EEPROM 18 of the IC card 3 in the set predetermined processing mode.

However, if the first card detection sensor 26 is turned on / off in S63, the process proceeds to S69.
To check whether a predetermined time (n seconds) has elapsed. If the first card detection sensor 26 does not perform the on / off operation during the elapse of the predetermined time (n seconds), the above-described S
When the first card detection sensor 26 is turned on / off while the predetermined time (n seconds) elapses (see the waveform diagram of FIG. 10), the processing of the predetermined time (n
S7 when the IC card 3 is put in and out twice within seconds)
The process proceeds to 0, and the processing mode is sequentially changed. In this embodiment,
For example, the time stored in the IC card 3 is changed to one of the processing modes of entry time, exit time, early exit time, flex entry time, and overtime time.

In the next step S71, the changed processing mode is displayed on the display 2 to notify the operator. And the above S
Return to 63. If the first card detection sensor 26 is still turned on and off by the operation of inserting and removing the IC card 3, the processing mode is sequentially updated by the number of times by repeating the processing of S70 and S71 again. When the processing mode is changed as described above and the desired processing mode is displayed on the display 2, the operator inserts the IC card 3 into the card R / W mechanism 28.

When the processes of S63 to S66 are executed and both of the card detection sensors 26 and 27 are on, after the processing mode changed in S67 is set,
The current time data (information) is stored in the EEPROM 18 of the IC card 3 in the processing mode changed in S68.
In the next step S72, the current time data (information) is stored in the IC card 3 in a predetermined processing mode, and the display 2 indicates that the processing is completed. Subsequently, the flow advances to S73 to check whether or not the second card detection sensor 27 has been turned off. When the IC card 3 is pulled out from the card insertion slot 4, first, the second card detection sensor 27 is turned off, the process proceeds to S74, and the processing mode displayed on the display 2 is erased.

At S73, the second card detection sensor 2
When 7 is on, the process proceeds to S35, where "Card Eject" is displayed on the display 2 to urge the operator to pull out the IC card 3. Then, in S76, it is checked whether the first card detection sensor 26 has been turned off. In this S36, when the IC card 3 is pulled out from the card insertion slot 4, the first card detection sensor 26 is turned off, and the current processing ends.

As described above, the processing mode can be sequentially changed according to the number of times the IC card 3 is inserted and removed, so that a troublesome switch operation is unnecessary, and the processing mode can be easily changed to a desired processing mode. Erroneous operation of the change can be prevented. FIG. 11 is a block diagram of a fourth modification of the present invention. In the figure, the same parts as those in the configuration of FIG. 2 described above are denoted by the same reference numerals, and description thereof will be omitted.

The voltage supplied from the power supply 7 is monitored by a power supply monitoring device 35. When the power supply switch 25 is turned off and the voltage decreases to a predetermined voltage or less, a power supply voltage reduction signal is output from the power supply monitoring device 35. Is output. Also,
The RTC (Real Time Clock) 36 is also called a time counter or an IC calendar, and automatically counts the date and time. The control circuit 6 can arbitrarily read the date and time from the RTC 36.

FIGS. 12 and 13 are flow charts for explaining a fourth modification of the processing executed by the control circuit 6. FIG. 12 is a flowchart for explaining a process when the power switch 25 is turned off, and FIG. 13 is a flowchart for explaining a process when the power switch 25 is turned on. Now, it is assumed that the power supply of the IC card device 1 is turned on. When the power switch 25 is turned off, a power supply voltage drop signal is output from the power supply monitoring device 35 and the control circuit 6
Will be notified.

The control circuit 6 which has received the power supply voltage lowering signal reads the date and time from the RTC 36 in S81, and reads the date and time of the IC card 3 composed of the nonvolatile memory in S82.
It is stored in the EPROM 18. Then, when the power supply voltage drops below the operating voltage of each device, the system goes down.

Next, the processing when the power is turned on again after the system is down will be described. In this case, when the power switch 25 is turned on, the power supply voltage increases, and the system starts operating when each device becomes operable. At that time, the control circuit 6 determines in step S83 that the RTC 36
The date and time are read out from the memory and stored in a register (not shown) or an SRAM 8 which can read and write at high speed. Here, this date is referred to as “date 1”.

Next, in S84, the date and time recorded in the EEPROM 18 when the power supply voltage has dropped is read. Here, this date is referred to as “date 2”. And S85
Then, “date 1” and “date 2” are compared. In the next S86, if the difference between “date 1” and “date 2” is n seconds or less (date 2−date 1 ≦ n seconds), the process proceeds to S86 and the processing mode is changed from m to m + 1. Therefore, when the elapsed time from when the power switch 25 is turned off to when the power switch 25 is turned on is n seconds or less, the plurality of processing modes can be sequentially changed.

In the next S87, m + changed in S86
It is checked whether or not one processing mode exists. If the changed processing mode of m + 1 does not exist, the flow shifts to S88 to return to the processing mode 1 of the initial value. Further, when the processing mode of m + 1 exists in S87, S
Go to 89. In S89, the display unit 2 displays the changed processing mode of m + 1. Then, the process proceeds to S90, where the current time data is stored in the EEPROM 18 of the IC card 3 in the changed processing mode.

In S85, if the difference between "date 1" and "date 2" is n seconds or more (date 2-date 1> n
In (seconds), it is determined that there is no need to change the processing mode, and the flow advances to S91 to store the current time data in the EEPROM 18 of the IC card 3 in the changed processing mode.
As described above, since the processing mode is sequentially changed by monitoring the time interval of the ON / OFF operation of the power switch 25, the processing mode can be sequentially changed according to the number of ON / OFF operations of the power switch 25. Therefore, the processing mode can be easily changed to a desired processing mode, and erroneous operation of changing the processing mode can be prevented.

In the above embodiment, the EE of the IC card 3
The case of changing the processing mode for storing the time in the PROM 18 has been described as an example. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a device for storing other information.
