Description

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 separate wire that displays call charges.

2. Description of the Related Art Conventionally, there is an automatic dialing device that automatically converts a pre-stored telephone number into a dialing signal and sends it to a telephone line by a simple operation. Such devices use microcomputers to store telephone numbers, create dial signals, etc., making them small, lightweight, and inexpensive. A telephone call charge display device is attached to nine individual telephones and automatically displays the call charge each time the telephone is used.

For each area code to which the telephone belongs, we have rate data for nine call destinations. In addition, special charges apply only to areas adjacent to the area codes of the three sources.
Separately, we have charge data according to the area code of the adjacent area.0 To obtain the call charge, use an input device that manually enters the area code of the destination you are dialing, and 1. It was necessary to have something called rate data built-in. Therefore, when a conventional device of the type was relocated to a location with a different area code, it was necessary to re-enter charge data according to the new area code. Also, 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 of reading the destination telephone number by mistake due to noise mixed in the telephone line. In that case, the display of call charges will be incorrect.

The present invention was made in order to solve the above-mentioned problems, and it is possible to memorize the telephone number of the person you call once in advance and automatically convert it into a dial signal with a simple operation. 2 to the telephone line, and displays on the display the telephone number that has been removed and the call charge that is accumulated as the call time elapses. To provide an automatic dialing device with H1 rate that is easy to use, convenient, and highly reliable, without having to be modified.

An embodiment of the present invention will be described in detail below with reference to the drawings.

Furthermore, it is now possible to change the contents of the destination telephone number, which is already stored, and to automatically send it as a dial signal, with a simple operation. In addition, through the display section 1 and the operation section 2, you can also display the destination telephone number, the number of seconds corresponding to the unit charge unique to the destination, and the cumulative call charge according to the call duration.03 is a display lamp. It is turned on manually at the call start signal and turned off at the call end signal at 9. In the 4Vi dial signal converter, 05, which is a converter for sending a dial signal to the telephone line, is a signal detector, which detects the state of the hook switch of the telephone and the response signal of the called party. Reference numeral 7 denotes a central processing unit, which is composed of a one-chip microcomputer/computer containing a control program for the entire apparatus, and is connected to the signal detection section 5.
The call start signal and call end signal detected in the above are input. Furthermore, inputs from the central processing unit 7I-i and the operating section 2 are constantly scanned, and the display section 1 is configured to display the time during normal times. In addition, it outputs telephone numbers to the dial signal converting section 4 in a predetermined order by inputting them to the operation section 20, calculates the call time corresponding to a unit charge according to one call destination, and calculates the call charge by counting the call time. displayed on the display section 1. Reference numeral 8 is a setting section consisting of four digital switches that allow you to input four digits excluding the first 0 of the area code of the station to which the telephone to which this device is attached belongs. Reference numeral 9 denotes a timer which provides a clock signal that is the difference in operating timing of the central processing unit @7. 10 is a data bus and 11 is a storage device. The data bus 10 is for exchanging signals between the central processing unit 7 and the storage device 11. The storage layer is a read-only memo! J (RoJ+2
It is composed of a read-only memory (RAM) 15;

Reference numeral 15 denotes an adjacent area code table in which data of area codes indicating areas adjacent to the central station are stored. Reference numeral 16 is a charge table that stores the call time that can be made per unit fee for calls within the area and @contact area 1 outside the area.

In particular, out-of-area calls are divided into groups according to the distance of the call, which exposes the public corporation's ``Taihaku 1'' as a separate fee system. Reference numeral 17 is a telephone number memory for storing several call destination telephone numbers with 9 call classifications. Reference numeral 018 is a call charge accumulation memory for storing the integrated value of call charges during a call.

FIG. 2 is a flowchart for explaining the operation fr of the present invention. Initially, the time is displayed during normal times, and if you lift the handset of the telephone and operate the operating section 2, you will automatically dial a pre-memorized destination telephone number. In the 19th step, the routine for determining whether there is human power from the operating section 2 is skipped, and the 20th step is executed. In step 20, the central processing unit 7 retrieves the destination telephone number selected from the telephone number memory 17 via the data bus 10, and sends it to the dial signal converter 4 in one step so that it becomes a specified dial signal. Output. Execute the next VC21 step. In step 21, the display unit 1Vc displays the telephone number of the destination to which the call is to be made, in sequence. Next, execute 22 steps. In 222 Teso, signal detection unit 5
When the caller sees the input signal and puts down the handset in the middle of dialing, it executes 23 steps. In step 26, the dial signal output process is stopped and the entire time is displayed on display section 1. After determining J, the initial state 1
Return to step 9.

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 telephone numbers have been output, and if not, 20, 21, 22, 24. 25 steps are repeated. 0 When all outgoing optical telephone numbers are output, 26 steps are executed.

In the 26th step, a response signal from the destination is monitored via the signal detection section 5, and if a signal is detected, the 27th step is executed. 2
In step 7, turn on the display lamp 6 to indicate that the call is in progress and press 1.
In the next 28 steps, the area code of the originating telephone set in the setting section 8 is read, and in the first 29 steps, the coordinates corresponding to the originating area code read in the coordinate table 14 in 28 steps are read. At the same time as reading the data sound, the corresponding adjacent station number is also read from the adjacent station number table 15.

Next, run all 30 stepso games. In the 6o step.

The first digit of the destination phone number you dialed in 20 steps is 0.
If it is not 0, it is determined that the call is within the area. If it is 0, read it with 29 steps 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 f! from the coordinate table 14 corresponding to the destination area code! : In step 031 to read, if the result is determined in 3° steps, if the call is within the area, then step 62.
66 steps for calls in adjacent areas, 34 steps for calls outside one area
The program is branched to execute each step. In step 62, 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. 64 steps calculate the distance between two points from the coordinate data of the source and destination stations.1
In the next 35 steps, the call time per unit charge corresponding to the distance value K TJ is read from the charge table 16.

Step 36 calculates the call time and the call time, and Step 57 multiplies the call time and call time per unit charge by the unit charge to obtain the call charge, and displays the call time and call charge per unit charge on display 1. indicate. In step 38, 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, 37, and 38 are executed again. 0If the call is ended, step 39 is executed next. In the 39th step, the display 2 lamp 3 is turned off.Then, in the 40th step, 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 ends.
After time-up, processing is performed to return to time display.

The process returns to the state of waiting for an operation input from the operation unit 2 again.

As described above, according to the present invention, by setting the area code to which the telephone to which the rate word automatic dialing device is installed belongs, the call time is automatically calculated based on the unit charge, which varies depending on the destination of the call. This allows you to reduce unnecessary long phone calls, and allows you to use the automatic dialing device with a single rate meter, no matter where in the country it is installed, by setting the area code to which it belongs each time. There is no need to replace or adjust parts. Therefore, no extra burden is placed on the user. In addition, since the destination phone is automatically converted to a dial signal and the original data is used to divide the charges, it is completely unaffected by noise mixed in the telephone line, and is therefore extremely reliable. We can provide an automatic dialing device with a high-quality old-fashioned dial.
