FIG. 4 is a diagram showing an example of a registration area of sales status data set in the RAM 6. Figure 4 (1)
Shows an example of the configuration of the daily total sales status data registration area 6a, and the total total for each data such as sales amount, sales quantity, and number of customers is registered. The registered content is updated and registered every time the sales of the product is registered. FIG. 4B is a configuration example of the sales status data registration area 6b for each product, in which the product name, sales amount, sales quantity, and the like are registered. With respect to the registered contents, every time the sales of a product is registered, the sales amount and sales quantity of the corresponding product are updated and registered.

FIG. 4C shows an example of the structure of the sales status data registration area 6c for each time zone, in which the time zone, sales amount, sales quantity, etc. are registered. As the time zone, a time zone in which the time from the opening time of the store to the closing time of the store is divided at appropriate time intervals is set, and in the example shown in FIG. The time zone is set by dividing the time until 20:00 by an hour, and the sales amount and the sales quantity for each time zone are registered.

The sales status data shown in FIG. 4 is transmitted as facsimile data to the facsimile device 3 through the public telephone line 2 by a procedure described later.

FIG. 5 is a flow chart for explaining a control data setting process for operating the facsimile communication function, and FIG. 6 is a diagram showing registered contents of the facsimile process data storage means 16. At step a1, it is judged whether the mode is the facsimile function setting mode. That is, it is determined whether or not the function changeover switch 25 described above is in the "setting 2" position. If the judgment is affirmative, step a
When the determination is negative, the other function in which the function changeover switch 25 is located is set.

In step a2, the transmittable data name Di
Is displayed on the display device 8, and it is determined in step a3 whether or not there is a setting instruction. When performing a setting instruction, the "1" key and the "#" key (non-additional registration / time key 41) are pressed from the key input device 7. If you do not specify settings,
Press the "0" key and the "#" key.

When there is a setting instruction in step a3, the process proceeds to step a4, the flag Fi = 1 is set, and the process proceeds to step a6. If there is no setting instruction, step a
5, the flag Fi = 0 is set, and the process proceeds to step a6. In step a6, it is determined whether or not all the settings of the transmittable data have been completed. If not completed, the process returns to step a2, the next transmittable data name is displayed, and the above operation is repeated. When the setting of the transmittable data is completed, the process proceeds to step a7.

In the present embodiment, as the transmittable data, the daily total sales status data D1 and the sales status data D for each product are described.
2. It is assumed that there are three pieces of data, sales data D3 by time zone, and here, the case where the daily sales status data D1 and the sales status data D3 by time zone are set as transmission data will be described.

That is, when the function changeover switch 25 is set to the position of "setting 2" as described above, the display device 8 first displays "Nikkei". The operator inputs “1” and “#” from the key input device 7. As a result, as shown in FIG. 6, the flag F in the flag data registration area 16a is
1 is set to "1". Then, on the display device 8,
It is displayed as "Shohinbetsuuriage". The operator inputs “0” and “#” from the key input device 7. As a result, the flag F2 in the flag data registration area 16a is "0".
Is set to. Further, subsequently, the display device 8 displays “Zicanta Ibetsu Uriage”. The operator inputs “1” and “#” from the key input device 7. As a result, the flag F3 in the flag data registration area 16a is set to "1". The data whose flag is set to "1" is converted into image data according to the procedure described later, and the facsimile apparatus 3
Sent to.

At step a7, the display device 8 displays "Synchronous" and then the transmission time input from the key input device 7 is registered in the transmission time registration area 16b shown in FIG.

In step a8, "Soushin Saki" is displayed on the display device 8, and then the facsimile number input from the key input device 7 is registered in the destination facsimile number registration area 16c shown in FIG. As a result, control data for operating the facsimile communication function is set in the facsimile processing data storage means 16.

After that, the function changeover switch 25 is set to, for example, the position of "registration", and normal commodity registration processing is performed. As described above, the function setting switch cannot be set to the “setting 2” position without the key 26 possessed by the owner or the like who is the manager. The settings cannot be changed without permission.

FIG. 7 is a flow chart for explaining the image data transmission operation by ECR1. In ECR1,
As described above, the automatic transmission function of automatically transmitting the designated information to the facsimile device 3 when the transmission time set in the facsimile processing data storage means 16 is reached, and the designation based on the transmission request signal from the facsimile device 3 It is possible to execute two types of transmission functions, that is, a so-called polling function for transmitting the stored information.

At step b1, it is judged whether it is the transmission time. That is, when the transmission time data in the facsimile processing data storage means 16 and the current time given from the clock circuit 10 coincide with each other and the time coincidence signal is given to the transfer controller 12, the process proceeds to step b2. If the transmission time has not been reached, the process proceeds to step b7.

At step b2, the transfer control section 12 refers to the registration data in the flag data registration area 16a of the facsimile processing data storage means 16, reads the data of the flag Fi = 1 from the RAM 6 and transfers it to the transmission data storage means 17. .. In the present embodiment, since the flags F1 and F3 are "1", the daily total sales status data and the sales status data by time zone shown in FIGS. 4 (1) and 4 (3) described above are read and transmitted. It is transferred to the data storage means 17.

At step b3, the communication control circuit 11 makes a calling operation to the facsimile apparatus 3 based on the destination facsimile number set in the destination facsimile number registration area 16c in the facsimile processing data storage means 16. When the facsimile device 3 receives the call and the line is connected, the transfer control circuit 13 supplies the data stored in the transmission data storage means 17 to the image data conversion circuit 14 to convert the data into image data in step b4. In step b5, the data is transmitted to the facsimile apparatus 3 via the public telephone line 2 by the communication control circuit 11. When the transmission of the image data ends, the line connection is disconnected in step b6, and the transmission operation ends.

If the transmission time has not come at step b1, the process proceeds to step b7 and the communication control circuit 1
At 1 it is determined whether a ringing signal has been received. If not received, the process returns to step b1, and if received, the process proceeds to step b8. In step b8, the call detection signal of the communication control circuit 11 is received by the call detection circuit,
This connects to the calling side via the public telephone line 2. In step b9, the calling side responds based on the transmission phase of the facsimile communication, and a predetermined facsimile communication protocol is performed.

In step b10, it is judged whether or not a polling signal has been received in the above protocol.
If the polling signal is not received, this is a so-called wrong telephone call, and the process proceeds to step b14, where the line is disconnected and the process ends.

When the polling signal is received, the process proceeds to step b11, the communication control circuit 11 controls the transfer control circuit 12, and the flag Fi = 1 of the flag data registration area 16a in the facsimile processing data storage means 16 is set in the same manner as described above.
Data from the RAM 6 and the transmission data storage means 1
Transfer to 7. At step b12, the transfer control circuit 13 supplies the transmission data in the transmission data storage means 17 to the image data conversion circuit 14 to convert it into image data,
Subsequently, in step b13, the communication control circuit 11 transmits the image data to the facsimile apparatus 3 via the public telephone line 2. When the transmission of the image data is completed, the line connection is disconnected in step b14 and the process is completed.

FIG. 8 is a diagram showing a signal sequence when image data is transmitted from the ECR1 side. ECR1
When a calling signal from the exchange is given to the facsimile apparatus 3 by the calling operation by the
R1 transmits a CNG signal indicating that the calling side is a non-voice terminal to the called facsimile machine 3. Receiving this, the facsimile machine 3 transmits a CED signal which is a called terminal identification signal to the ECR 1, and subsequently sends a DIS signal which is a digital identification signal. The DIS signal is a signal indicating that the called facsimile machine 3 has a CCITT (International Telegraph and Telephone Consultative Committee) standard reception function. The calling side recognizes the receiving function of the facsimile apparatus 3 by this DIS signal.

Subsequently, a DCS signal which is a digital command signal is transmitted from the ECR 1 to the facsimile machine 3. DC
The S signal is a command signal indicating a function set among the standard functions indicated by the DIS signal. As a result, in the facsimile machine 3 which is the called side, the EC which is the calling side is
The receiving function required for receiving the image data from R1 is selected.

Subsequently, a training signal and a TCF signal which is a training check signal are transmitted from ECR1. The state of the modem which receives the image data is confirmed by the training signal and the TCF signal, and it is confirmed whether the modem can receive the image data. After that, the CFR signal which is the reception preparation confirmation signal is transmitted from the facsimile apparatus 3. The CFR signal is a response signal indicating that the procedure before sending the image data is completed and the sending of the image data may be started.

In ECR1, receiving the CFR signal,
Image data is sent to the facsimile apparatus 3 following the training signal. When the transmission of image data is completed, EC
R1 sends out an EOP signal which is a procedure end signal. EO
The P signal is a signal indicating the end of image data and the absence of other image data to be transmitted. The facsimile device 3 responds to the EOP signal by sending a message confirmation signal MC
Send the F signal. In response to the MCF signal, the ECR 1 sends a DCN signal, which is a disconnection command signal, to the facsimile machine 3 to disconnect the line.

FIG. 9 is a diagram showing a signal sequence when image data is transmitted based on a polling instruction from the facsimile device 3 side. The calling operation from the facsimile machine 3 causes the calling signal from the exchange to be ECR1.
When the line is received and the line is connected, the facsimile machine 3 sends out a CNG signal. The ECR 1 sends the CED signal and the DIS signal to the facsimile device 3.

After that, the facsimile apparatus 3 sends a DTC signal, which is a digital transmission command signal, to the ECR1. The DTC signal is a signal used as a response to the DIS signal when delegating the transmission right of image data to the called terminal. As a result, the transmission right of the image data is transferred to the ECR1, and thereafter, the procedure after the DCS signal shown in FIG. 8 is executed to transmit the image data from the ECR1 to the facsimile apparatus 3.

As described above, according to this embodiment, ECR1
Since the sales status data of the ECR1 is converted into image data and transmitted, the registration data of the ECR1 can be easily transmitted to any place, and the recording paper received and printed by the facsimile device 3 can be immediately viewed. Since the sales status data can be confirmed, the data can be easily managed.

Further, by using the polling function, data such as the sales status of the ECR 1 can be received from any time and place, so that convenience in data management is significantly improved. When using the polling function, it is possible to prevent data leakage by setting a personal identification number for permitting transmission of sales status data.
