DETAILED DESCRIPTION OF THE INVENTION The present invention is attached to a telephone and automatically calls a stored telephone number by button operation.
This invention relates to an automatic dialing device with a charge meter that displays call charges.

2. Description of the Related Art Conventionally, there is an automatic dialing device that automatically converts a pre-memorized telephone number into a dialing signal and sends it to a telephone line by a simple operation. This type of device uses a microcomputer to memorize telephone numbers and create dial codes, making it small, lightweight, and inexpensive. 9 Call charge display devices are attached to each telephone.1. It automatically displays call charges each time the telephone is used, and has charge data corresponding to the destination station for each area code to which the telephone belongs. Also, special charges apply only to areas adjacent to the area code of the calling station (9), so we have separate fee data corresponding to the area code of the area of the adjacent station. In other words, in order to obtain the combined rate, it was necessary to store in the built-in 12 an input device for inputting the area code of the destination to be dialed, and rate data corresponding to the location where the one-call rate display device was installed. Therefore, if such conventional equipment is relocated to a location in a different area code.

It was necessary to re-enter the rate data according to the new area code. Also, 9. When detecting the dialed number of the destination, if the signal on the telephone line is input through an input device, there is a risk that the destination telephone number may be read by mistake due to noise mixed in the telephone line. , in that case 1
Call charges will be displayed incorrectly.

The present invention has been made to solve the above-mentioned problems, and it is possible to memorize in advance the telephone number of the person you are calling, and automatically convert it into a dial signal with a simple operation. 17. The device displays the telephone number sent at that time and the call charge that is accumulated as the call time elapses on the display.The area code of the adjacent area is included, making it easy to use, convenient, and reliable. To provide an automatic dialing device with one key word.

FIG. 2 is a flowchart 1 for explaining the present invention in detail.
・It is. At first, under normal conditions, the time will be displayed and the handset of the telephone will be lifted.

When attempting to automatically dial a pre-memorized destination phone number by operating the operation unit 2, the routine skips the routine for determining whether there is an input from the operation unit 2 in step 19 and continues in step 20. Execute.

In step 20, the central processing unit 7 sends the destination telephone number selected from the telephone number memory 17 via the data bus 10. The dial signals are taken out and output in one step to the dial signal converter 4 in order so as to become a prescribed dial signal. Next 2
Execute 1 step. In step 21, the telephone number of the destination to be called is displayed on the display section 1 in sequence/flip-by-page. Next, execute 22 steps. In the 22nd step, the input signal from the signal detection section 5 is checked, and when the handset is put down in the middle of dialing, the 26th step is executed.

In step 23, the process of canceling the output of the dial signal is performed and the time is set to be displayed on display section 1, and then the process returns to step 19, which is the initial state. If no handset is placed, the first 24 steps are executed.

In step 24, timer processing is performed to output a specified signal to the dial signal converter 4. In step 25, it is determined whether all phone numbers have been output, and if not, 20.21, 22. 24. Repeat each step of 25. When all destination phone numbers are output, 26 steps are executed. In step 26, the response signal from the destination is monitored via the signal detection section 5. If there is a signal.

Execute 27 steps. In the 27th step, the display lamp 3 is turned on to indicate that a call is in progress, and in the first 28th step, the area code of the originating telephone set in the setting section 8 is read, and in the first 29th step, the coordinate table 14 is read.
At the same time, read out the hole coordinate data corresponding to the source area code read in 28 steps from the table. Adjacent station number table 1
The corresponding adjacent station number is also read from the table No. 5. Next, perform 30 steps.

In step 60, it is checked whether the first digit of the telephone number of the destination called in step 20 is O, and if it is not 0, it is determined that the call is within the area. If it is 0, read it in step 29 and see if it matches the adjacent station number. If they match, it is determined that the call is in an adjacent area. If they do not match, coordinate data corresponding to the destination area code is read from the coordinate table 14.

At step 61, depending on the result determined at step 60, the process is branched to execute 52 steps if the call is within the area, 66 steps if the call is in an adjacent area, and 34 steps if the call is outside the area. In step 32, the call time per unit charge corresponding to calls within the area is read from the charge table 16. In step 63, the call time corresponding to the unit charge corresponding to the adjacent area call is read from the charge table 16. The 34th step calculates the distance between two points from the coordinate data of the source and destination stations, and reads out the call time per unit charge corresponding to the distance value found in the 9th and 65th steps from the rate table 16. . In step 36, the call time is counted, and in step 67, the unit charge is calculated from the value of the call time and the call time per unit charge, and the call charge is calculated, and the call time and call charge per unit charge are displayed on the display section 1. . 58
In step 1, it is detected via the signal detection unit 5 whether the call has ended or not, and if the call has not ended, steps 36, 57, and 38 are executed again.0If the call is ended, step 69 is executed next. In step 69, the display lamp 6 is turned off. Next, in step 40, a timer is started to display the calculation result of the call charge for a certain period of time so that the user can check it after the call is over, and after the time is up, a process is performed to return to the time display, and the operation panel is operated again. The process returns to the state where it waits for the operation input from step 2.

As described above, according to the present invention, by setting the area code to which the telephone to which the automatic dialer/L device with charge meter belongs belongs, the call time can be automatically calculated for the unit charges that vary depending on the nine call destinations. Since you can know the cost of a single call, you can reduce unnecessary long phone calls, and you can use the automatic dialing device with a single charge meter, no matter where in the country it is installed, by setting the area code to which it belongs each time. Therefore, there is no need to replace or adjust parts. Also.

There are four fugital switches in the setting section.

Setting work is easy. In addition, since the telephone number of the called party is automatically converted into a dial signal and the original data used for transmission is used to calculate charges, it is completely unaffected by noise mixed in the telephone line, and is therefore extremely reliable. We can provide high-cost autopsy automatic dialing equipment.
