It is used to input a ticket number to the CPU 44 via the interface circuit 43 in place of the reader 6.

An outline of the operation of the key information automatic input device having the above-described configuration will be described with reference to an example of a data transfer procedure shown in FIG. Now, when the multiplexer 46 is on the A terminal side as shown in the figure by the selector signal from the CPU 44, the control box 1 transmits the TxD
When the display data (enter the landing data) is transmitted via the line, the handy keypad device 2 which has normally received the display data sends an ACK to the RxD line.

The CPU 44 monitoring the data on the TxD and RxD lines fetches the display data on the TxD line and the ACK on the RxD line, and
Is compared with the data in the data table, and when they match, the selector signal is inverted and the multiplexer 46 is switched to the B terminal side opposite to the illustration. After that, the CPU 44 generates dummy key information corresponding to a code generated by operating the “ride point” key of the handy keypad device 2 and outputs this to the dummy RxD.

Reference numeral 44 denotes C based on the coordinate data from the position information generator 5.
The district code data of the boarding place created by the PU 44 is output to the dummy RxD as key information.

Thereafter, the control box 1 receiving the district code information transmits display data (press the set key if the boarding place is correct), and the CPU 4
Reference numeral 4 performs operations such as generating dummy key information corresponding to the operation of the “set” key of the handy keypad device 2 and transmitting it to the control box 1.

It is also possible to use the district code data from the bar code reader 7 instead of the coordinate data from the position information generator 5 for the district code data of the boarding place. In addition, by reading the ticket number of the receivable ticket from the ticket by the card reader 6, the receivable ticket input can be automatically input without depending on the key operation of the handy keypad device 2 in the same manner as described above. .

The details of the operation of the key information automatic input device described above will be described with reference to the flowchart of FIG. The CPU 44 starts the operation by turning on the power supply by the power supply circuit 47, and in the first step S1, generates a selector signal for setting the multiplexer 46 to the A terminal side. Thereafter, the process proceeds to step S2, where the TxD and RxD lines are monitored, and the result of this monitoring is compared with the data table in the memory 45 in the following step S3. It is determined whether they match. If the determination in step S3 is NO, steps S2 and S3 are repeated, and
It waits until the judgment of 3 becomes YES.

If the determination in step S3 is YES, the process proceeds to step S4, where it is determined whether or not the STB line is off. If the determination is NO, the process waits until the STB line is turned off. If so, the process proceeds to step S5. In step S5, it is determined whether or not the printer is online based on the RDY line. If the determination is NO, the process waits to be online, and if the determination is YES, the process proceeds to step S6.

In step S6, the multiplexer 46 is switched to the terminal B side by the selector signal, and the process proceeds to step S7 to transmit the "ride location" code. Thereafter, the process proceeds to step S8, where it is determined whether or not the display data has been normally received. If the determination is NO, the process proceeds to step S9, where NAK is transmitted, and the determination in step S8 is YE.
Steps S8 and S9 are repeated until S is reached. If the determination in step S8 is YES, the process proceeds to step S10, transmits ACK, and then proceeds to step S11.

In step S11, a "district" code is transmitted based on data from the position information generator 5 or the bar code reader 7. Thereafter, the process proceeds to step S12 to determine whether the display data has been normally received.
In step S13, the process proceeds to step S13, where NAK is transmitted.
12 and S13 are repeated. The determination in step S12 is Y
In the case of ES, the process proceeds to step S14 to transmit ACK, and then proceeds to step S15.

In step S15, a "set" code is transmitted. Thereafter, the process proceeds to step S16 to determine whether the display data has been normally received. If the determination is NO, the process proceeds to step S17 to transmit NAK and repeat steps S16 and S17 until the determination in step S16 becomes YES. . If the determination in step S16 is YES, the process proceeds to step S18 to end a series of operations, and returns to step S1.

According to the embodiment described above, the "ride point" key and the "drop-off point" for inputting a boarding place or a drop-off place can be input without operating the key operation section 22 of the handy keypad device 2. Keys, numeric keys for entering a three-digit district code, and data generated by pressing the "set" key can be automatically entered. Also, in the case of entry of transit points or unpaid (paper ticket) input Since the necessary key information can be automatically input without any key operation, the troublesome and complicated key operation can be omitted without changing the control box 1 or the handy keypad device 2 which is the main station. Can be.
