To do.

[Embodiment] The present invention will be specifically described below based on an embodiment shown in FIGS. 2 to 6.

Schematic Configuration (FIG. 2) First, the outline of the present embodiment will be described with reference to FIG.
In this embodiment, optical signals (infrared rays) are transmitted and received between the ECR 11 and the name plate device 12. That is, a communication device is built in a name plate device 12, which is generally called a name plate, and predetermined data is automatically and repeatedly transmitted from this communication device. When the person wearing the name plate device 12 having the communication device on his body approaches the front of the ECR 11, the data transmitted from the name plate device 12 is received by the receiver 13 provided on the front of the ECR 11. To be received. As a result, the ECR 11 prohibits the input operation based on this received data. Further, on the front surface of the ECR 11, there is provided a transmitting section 14 for transmitting predetermined data to the name plate device 12 by an optical signal. Therefore, in this embodiment, EC
Data can be transmitted and received by both the R11 and the name plate device 12.

ECR11 has a keyboard 1 that is usually equipped.
5, display panel 16, printer 17, drawer 18, rotation indicator 1
9th grade is provided. In addition, a pin-type holder PH for mounting the nameplate device 12 on the body is provided on the back surface of the nameplate device 12.

Circuit Configuration (FIG. 3) First, the circuit configuration of the name plate device 12 will be described. The name plate device 12 has a CPU 21 as a core, and sets the transmission data from the ECR 11 received by the receiving unit 22 in the memory 23. In this case, the ECR 11 transmits an operator number (person in charge number), a current time for time adjustment, and an actual working time peculiar to the operator by an optical signal. The current time is set in the memory 23, and the current time is set in the clock circuit 24 to adjust the time. Then, during normal operation, the CPU 21 stores the current time obtained by the clock circuit 24 and the memory 23.
Compared with the actual working time set in, the data indicating whether the current time is within the actual working time or outside the actual working time is given to the transmitter 25 together with the operator number in the memory 23,
These data are transmitted to the ECR 11 by an optical signal. In addition, 26 is a power supply battery, 27 is a crystal oscillator added to the clock circuit 24, and 28 is a reset switch.

Next, the circuit configuration of the ECR 11 will be described. CPU31 is RO
A setting process for setting predetermined data for the name plate device 12 and a normal registration process are controlled according to a microprogram stored in advance in the M32. That is, CPU3
In 1 in the setting mode, the transmitting unit 14 transmits the operator number and the actual working time for the operator to set the name plate device 12, or in the registration mode, captures the sales data input from the key input unit 33. , The sales totals by department, the sales totals by person in charge, etc. are accumulated in the RAM 34. The key input operation in this registration mode is permitted on the condition that predetermined data is received from the name plate device 12. Reference numeral 35 is a printing unit for printing sales data, 36 is a display unit, and 37 is a clock circuit.

Setting Operation (FIGS. 4 and 5) First, the operation for setting the operator number, the actual working time, and the like from the ECR 11 to the name plate device 12 will be described. Note that FIG. 4 is a flow chart showing the operation in this case, and FIG.
4B shows the operation on the ECR 11 side, and the setting operation will be described below in chronological order in the order of to in the figure.

When the reset switch 28 of the name plate device 12 is operated, the name plate device 12 executes the operation according to the flow of FIG. 4 (A).

First, the reset process (step A1) is executed, and the contents of the memory 23 are cleared. Then, it waits for reception until the preset data is transmitted from ECR11.
(Step A2).

, ECR11, setting mode, the 4th
The operation according to the diagram (B) is executed. First, preset transmission data is created by matching the operator number (step B1) entered as a numerical value and the actual working time (step B2) for that operator with the current time (step B3) read from the clock circuit 37 (step B4). FIG. 5 (B) shows the data structure created in this way,
This data is first the operator number, then the current time hours (HH), minutes (MM), seconds (SS), and the actual working time start time (hours, minutes, seconds), end time (hours, minutes, seconds), and last. To
It is composed of LRC (horizontal parity for error detection).
The preset transmission data created in this way is transmitted from the transmission unit 14 to the name plate device 12 (step B5).

When the name plate device 12 receives the data transmitted from the ECR 11, it detects a reception error based on the LRC data (step A3). As a result, when a reception error is detected, the process returns to step A2 to receive again. I will be waiting.

, ECR11 clears the timer counter (not shown) after transmitting the preset data (step B6), and the predetermined data (operator number, etc.) is transmitted from the name plate device 12 within a fixed time. Wait until reception (steps B7, B8, B9). Here, when a reception error (step A3) occurs on the name plate device 12 side, the name plate device 12 is in a reception waiting state, so that no data is transmitted from the name plate device 12 even after a certain period of time has elapsed. I haven't been. Therefore, in such a case, if a certain period of time is exceeded and it is detected in step B9, the process returns to step B3, the current time is read again, new preset transmission data is created, and the operation is retransmitted. It is executed repeatedly.

As a result, when the correct data is received on the name plate device 12 side, the operator number from the received data,
While extracting the actual working time and presetting it in the memory 23,
The present time is set in the clock circuit 24 to adjust the time (steps A4, A5, A6).

When the data transmitted from the ECR 11 is set in this way, the name plate device 12 enters the normal operation state. That is, the current time is read from the clock circuit 24 (step A7), this current time is compared with the actual working time set in the memory 23 (step A8), and as a result, whether the current time is within or outside the actual working time is determined. Check (step A9). here,
If it is during actual working hours, set the hour flag (step A1
1) If it is outside the actual working hours, reset the in-hour flag (step A10). And memory 2 in this time flag
Transmission data is created by combining the operator numbers stored in 3 (step A12). FIG. 5 (B) shows the data structure in this case.
It consists of operator number and LRC. The transmission data created in this manner is repeatedly transmitted from the transmission unit 25 to the ECR 11 at regular intervals (step A13). Then, the process returns to step A7, and the above operation is repeated.

, ECR11 receives the data from the nameplate device 12, it is detected in step B7, step B1
Go to 0, check if it is a reception error, and if it is a reception error, return to step B3, but if correct data is received,
The data indicating the end of setting is displayed (step B11) and printed (step B12).

Normal operation (Fig. 6) Normally, the ECR 11 side executes the operation according to the flowchart shown in Fig. 6, and the name plate device 12 side executes the operation shown in Fig. 5 (steps A7 to A13). ing.

ECR11 side is in registration mode, nameplate device 1
Waiting to receive the data sent from 2 (see FIG. 5 (B)) (step C1), when the data shown in FIG. 5 (B) is received, a reception error is checked (step C2). As a result, if there is a reception error, it waits for reception again. When the data is normally received, the operator number is extracted from the received data (step C3), and it is checked whether the operator number is the manager number (step C4).

If it is not the manager number, the in-time flag is extracted from the received data and it is judged whether or not it is set (step C9). If the time flag is set now, the process proceeds to step C6 to permit the registration operation, but if the time flag is reset, an error message is displayed (step C10) and an error indicating that it is outside the actual working time After performing the process (step C11), step C1
Return to In this case, when the manager is called and the manager normally receives the data transmitted from the name plate device 12 worn on the body, the process proceeds from step C4 to step C5, and the operator number can be manually entered. It is ready for input (step C5). In this case, when the manager inputs the operator number, the process proceeds to step C6, and the registration operation by the operator is permitted.

In this way, when the registration operation is permitted,
Enter the sales data and enter the sales data into RAM3
The registration processing for accumulating within 4 is executed (step C7).
And during this registration process, the name plate device
In the idle state of the data repeatedly transmitted from 12, that is, in the interval (step C8), this is detected and the process returns to step S1. Therefore, such an operation is executed at intervals of the data repeatedly transmitted from the name plate device 12.

Modifications / Applications (1) In the above embodiment, the actual working time etc. was transmitted from the ECR 11 and set in the name plate device 12.
An input means such as a setting switch may be provided on the 12 side. In this case, the name plate device 12 side does not need the receiving function.

(2) Moreover, even if the preset actual working time is transmitted from the name plate device 12 side and compared with the current time on the ECR 11 side, if the result is within the actual working time, the input operation may be permitted. Good.

(3) In the above embodiment, the in-time flag and the operator number are transmitted regardless of whether or not the current time is within or outside the actual working time. However, if the current time is outside the actual working time, it is not transmitted. May be. In this case, transmission power is saved on the name plate device 12 side.

(4) In addition, the above-mentioned embodiment is ECR11, name plate device 1
Although it is applied to 2, it can also be applied to other data processing devices and portable small electronic devices.
