Next, the reading operation of the card reader 36 for reading the card will be described in detail with reference to the flowchart of FIG.

As shown in FIG. 5A, reading of card data is performed by interruption by a read clock signal (RCL). In step S1, it is determined whether a card has been inserted into the card insertion hole 4. This determination is made based on whether the card load signal is high or low. If it is high, it is determined that it is inserted, and the process proceeds to step S2. In step S2, it is determined whether or not the read clock signal (RCL) has fallen. When it falls, the process proceeds to step S3, where an interrupt process is performed.
In the interrupt processing, one bit of the card data is written to the address of the card data buffer pointed by the CD storage pointer (see FIG. 8) as shown in FIG. Subsequently, the CD storage pointer is incremented for writing the next data (step S302). By the above interrupt processing,
The data read by the card reader 36 is temporarily stored in a card data buffer.

Next, the operation before printing using the slip printer of the present invention, that is, the operation of the normal print mode process will be described with reference to the flowchart of FIG. This operation is executed when the power of the slip printer is turned on, and when the card is not inserted or not printed.

In step S11, an operation for reading the time data from the clock IC 37 and updating the time data in the RAM 33 is performed. In step S12, the card reader 3
6, processing of the key 11 and the sensor 27 is performed.

In step S13, when the removal of the card from the card reader 36 is detected by the low level of the card load signal, the contents of the card data buffer are prevented from being rewritten by inserting a new card. Therefore, the interruption by the read clock signal is prohibited. In step S14, the read card data is checked. This check is performed based on whether predetermined data (DEL function character) exists at the beginning and end of the data string, and whether the parity is correct.

If the card data is determined to be correct by the above check, the process proceeds to step S16. On the other hand, when it is determined that it is not correct, the process proceeds to step S15,
The liquid crystal display device 1 is inserted so that the card is inserted again.
An error message is displayed in 2. Then, step S21
(See FIG. 12).

In step S16, an operation of checking predetermined card type identification data is performed. This determination is performed based on card determination information registered in advance for each card. In step S17, the value in the card data buffer is converted to character string data of alphabets, numbers, kana (ANK) or kanji, and stored in the card data area. For example, data of a doctor card is stored in the DR card data storage area of FIG.

In step S20, the above card data is displayed on the liquid crystal display device 12.

As described above, the transfer of data from the card data buffer to the card data storage area corresponding to the card has been completed, and the flow advances to step S21 to execute the operation of initializing the CD storage pointer. Then, the process proceeds to step S22, where the interruption by the read clock RCL is permitted, and the process returns to step S11.

Next, in step S12, when it is determined that the doctor key is turned on, the process proceeds to step S23, where the DR read pointer is incremented, and the DR card data at the next position is read from the DR card data storage area. Is displayed on the liquid crystal display device 12 (step S24). By repeating this, a desired doctor name is selected.

Next, when the comment key is turned on in step S12, the process proceeds to step S25, where C
The T read pointer is incremented and the next position C
T card data is read from the CT card data storage area and displayed on the liquid crystal display device 12 (step S).
26). By repeating this, a desired comment is selected.

Next, if it is determined in step S12 that the first paper detection sensor 27 has been turned on, the operation proceeds to print control. The details of the print control are described in Japanese Patent Application No. 4-25986, "Slip Printer Having Slip Parameter Setting Function," of the same applicant, and a description thereof will be omitted.

When the slip key is turned on in step S12, the flow advances to step S29 to increment the SP read pointer (see FIG. 9) by one. Next, proceeding to step S30, the slip parameter indicated by the SP read pointer is displayed on the liquid crystal display (LCD) 12.

Each time the slip key is turned on, the SP read pointer is incremented and the preset slip parameters of slips 1 to 5 are sequentially displayed. Thus, the operator can select a slip parameter suitable for the type of slip to be printed.

Next, when the stop key is turned on in step S12, the flow advances to step S51 to determine whether printing is in progress. If this judgment is affirmative,
Proceeding to step S52, printing is stopped and the slip is discharged. On the other hand, if the judgment is NO, step S5
Proceed to 3 to execute date mode processing.

Then, the content shown in FIG. 15A, that is, "Smallest indian food" is displayed. This informs the user that the issue date will be printed.

In the state of step S502, for example, if no operation is performed for one second (step S504 is affirmative),
The date mode is set to the issue date printing mode, and the flow advances to step S516 to change the display on the liquid crystal display device to the patient name display. In this state, when the slip is inserted into the printing unit and the first sensor 27 is turned on, printing is performed. The print example is as shown in FIG. 14A, and the date of issue (December 28, 1991, 15:36) is printed on the slip.

If the stop key is turned on at the time when "Small squirrel" is displayed in step S502 (Yes in step S503), step S502 is executed.
Proceeding to 505, the date mode is changed to the no issue date printing mode. At this time, the date mode data becomes 0.
Next, proceeding to step S506, the liquid crystal display device
The content shown in FIG. 15 (b), that is, "Swingfish incineration" is displayed. This informs the user that the issue date is not printed.

Thereafter, for example, if no operation is performed for one second (step S508 is affirmative), the date mode is set to the issue date non-printing mode, and the flow advances to step S516 to change the display on the liquid crystal display to the patient name display. . When printing is performed on the slip in this state, a printing without the printing of the issue date is obtained as shown in FIG.

Next, in step S506,
If the stop key is turned on when "Small cinnamon" is displayed (Yes at Step S507), the process proceeds to Step S509, and the date mode is changed to the reservation date mode. At this time, the date mode data is 2.

Then, in step S510, the current year (○) and month (×
×), date (△△) data is read and stored in the reserved date data storage area. Next, in step S511, FIG.
(c), for example, "Yakubibi 1991
"-12-28" is displayed on the liquid crystal display device to inform the user that the reservation date printing mode has been entered and that the current date is December 28, 1991.

At this time, if the stop key is further pressed (Yes at step S512), the process proceeds to step S514, where the date data is incremented, and step S515 is performed.
In, the reservation date is updated and stored. The processing of steps S511 to S515 is continued until the desired reservation date is reached. At this time, if the day data becomes 32, 0
Return to 1 and increment the month data. When the month data becomes 13, the process returns to 01, and the year data is incremented. FIG. 15D shows a display example at this time.

When the desired appointment date is reached, if the user is left for about one second (step S513 is affirmative), the appointment date is determined, and the flow advances to step S516 to change the display on the liquid crystal display to the patient name display. . An example of printing in this state is shown in FIG.
(c). That is, the reservation date is printed below the doctor's name.

As described above, according to the date mode processing of the present embodiment, an arbitrary one can be selected from three types, that is, printing with issue date, no printing with issue date, and printing with reservation date.
