When set to any of the above, the telephone number registered in that area will be displayed twice on the display section 2g.

That is, when the call switch 2f is operated once, "1" is displayed on the number display window and the first four digits of the telephone number are displayed, and when the call switch 2f is operated next, "2" is displayed on the number display window. The remaining 4 digits of the phone number will be displayed.

Then, when the call switch 2r is operated again, "1" is displayed in the number display window, and the display returns to the first four digits of the telephone number.
It will be displayed digit by digit.

Next, the second invention will be explained in detail.

The system of the second invention is a further improvement of the first invention.

In this invention, when the communication control means 3 is activated to sequentially transfer the entry/exit display data accumulated in the transfer data storage means 7 of the entry/exit display system to the plurality of entry/exit display systems, the controller 2 This is valid when the additional data for the entry/exit display data is input from the display operation terminal 1, etc., and the newly added data is valid for the destination system to which the entry/exit display data has not been transferred yet. The data is added to the entry/exit display data already stored in the transfer data storage means 7 and transferred, and to the transfer destination where the transfer has already been completed,
When one order of transfer processing is completed, only additional data is transferred.

For example, FIG. 11 shows the operation when the data accumulated in the transfer data storage means 7 is continuously transferred to four transfer destinations from the 1st district to the 4th district, and after the transmission time has elapsed. , when transferring the accumulated data sequentially from the first district to the fourth district, if additional data is input to the controller side during the transfer of the third district, the data will be transferred to the third district and the fourth district. The first district is transferred with additional data added to the end of the stored data, and the transfer has already been completed.

It is understood that for the second district only additional data will be transferred.

As shown in FIG. 12, the presence or absence of additional data may be checked for each period TO in which the accumulated data is divided into a predetermined number (for example, 5) when transferring the accumulated data.

After li, the third invention system will be explained.

FIG. 13 shows the system configuration of this third invention using a functional block diagram.

In addition to the controller 2 and the communication control means 3, the transfer data storage means 7 is provided with a standby time calculation means 9.

The system of the present invention is effective when transferring attendance/exit display data to another system and it becomes necessary to transfer the data again because the telephone line is in use. In this third invention, the waiting time at the time of retransfer is calculated by the waiting time calculation means 9 and is determined according to the length of data to be transferred, so that if the data to be transferred is short, the data is If the data is retransmitted and the data is long, the data is retransmitted after a correspondingly long waiting time.

The waiting time may be calculated by, for example, multiplying the data length stored in the transfer data storage means 7 by a certain constant.

FIG. 14 shows the retransfer operation in the third invention in comparison with the case of a conventional system that retransfers after a certain waiting time. Compared to the case where the waiting time T for starting retransfer is constant (see FIG. 14(b)), as the accumulated data lengths D1 to D4 become sequentially longer, the waiting time T1 to T3 for starting retransfer increases.
It is understood that the length is also set to be long (see FIG. 14(a)).

〔Effect of the invention〕

According to the first invention, after the data to be transferred is accumulated during a predetermined transmission time, the data is transferred using a telephone line, so there is no need to concentrate at the beginning of work, the end of work, lunch time, etc. Moreover, the number of times the telephone line is used can be reduced, and an economical attendance/exit display system can be provided.

According to the second invention, newly added data can also be quickly transferred when transferring to a plurality of transfer destinations after a predetermined transmission time has elapsed.

According to the third invention, when the telephone line is in use, the waiting time for retransfer changes depending on the length of data to be transferred, thereby reducing the possibility of collision at the time of retransfer.
