Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic dialing device that can automatically store subscriber telephone numbers dialed by turning the dial of a telephone by mechanical means.

Conventional automatic dialing devices use an electronic circuit to create the information necessary to operate the exchange in order to call the other party, and send it out on a lead wire connected to the telephone line. The dialing device and telephone line must be connected with a lead wire. However, like the power plugs of general electrical appliances,
The telephone line is not configured so that users can easily connect and use it, and the construction must be carried out by a professional and qualified construction worker. Therefore, it may not be possible to easily install or remove the automatic dialing device. Moreover, telephones are sometimes used for emergency communications, and it would be extremely troublesome if the telephone could not be answered due to malfunction.

Therefore, automatic dialing devices connected to telephone lines are required to have high reliability, which inevitably causes an increase in costs.

The present invention has been made in view of the above points, and an object of the present invention is to provide an automatic dialing device that rotates the dial of a rotary telephone using an electric motor in response to input of a telephone number and automatically dials the dial. For this purpose, the phone is equipped with a drive device that rotates the dial, a control device that controls the rotation angle and speed, and a keyboard that inputs input to the dial, and the control device and the drive device are connected via a connection line to the telephone. kkM l 4 six! +z

The automatic dialing device of the present invention has the following four functions. The first function is to memorize the frequently used telephone number of the other party and call the other party by lifting the handset of the telephone and operating the other party's call key. The second function is to input and memorize frequently used telephone numbers of other parties using the keyboard. The third function is to pick up the handset and quickly enter the telephone number on the keyboard, then dial the number twice without making any mistakes to call the other party. The fourth function is that if the person you called is busy, you can automatically repeat the same number by placing the handset down, lifting the handset again, and operating the call key. It is.

Various functions of an embodiment of the automatic dialing device of the present invention will be described below with reference to FIGS. 4 and 5.

In step A1, one-chip microcomputer 1
6 The contents of the built-in read/write memory (RAM) are 0.
Clear by writing. In step A2, the state of the stop switch 15 is detected, and if the stop switch 15 is off, step A3 is executed. A3
In step A4, the transistor group 20 is controlled so that a current flows through a specific coil of the excitation coil group 19 so that the rotation direction of the pulse motor 11 becomes the rotation direction in which the dial 12 returns, and this state is maintained for 12 hours in step A4. Therefore, the pulse motor 11 rotates by one step angle. Next A
Return to step 2 and if the stop switch 15 is off.

A3. Execute step A4 and rotate the pulse motor 11 by one more step. Therefore, the pulse motor 11 rotates until the stop switch 15 is turned on.

The four discs 13 are now set at the initial position.

In step A5, the pulse motor forward rotation flag is set to on. In step A6, the states of the keyboard 6 and changeover switch 8 are checked. In step A7, the dial speed is set to 10PPB from the state of changeover switch 8,
20PPB, the pulse width of one step applied to the excitation coil group 19 which determines the rotational speed of the pulse motor 11 is set by step A8 or A9. In step A10, if the reset key is pressed, step A11 is executed to turn off the 1 display 7, and then the process returns to step A1. In other words, if you press the reset key, dial 12
Even if the rotating operation is in progress, it is immediately stopped and the nine discs 13 are returned to the initial position. By executing step A1, the initial P state is returned even if various keys are being operated.

At step A12, if there is key human power and the key human power is effective on the program, the process moves to step A13.

If there is no key power or if the key power is invalid even if there is key power, the process moves to step A14.

In step A13, the key data is edited according to the contents of the key manual input. This has the following four i-conjunctions. The first is to memorize frequently used phone numbers, using the function keys and numeric keys.

When key operations are performed in a predetermined procedure, a telephone number is stored in a key designated by the key operation.

The second is when you try to dial a phone number that is memorized, it calls up the contents of the memorized key.

Store in register. Then, turn on the pulse motor operation flag. The third case is when attempting to dial by pressing numerical keys from 0 to 91, and the numbers are stored in the register in the order of the keys pressed. Also, turn on the pulse motor operation flag.

Fourth, if the number you dialed is busy, you press the redial key to dial the same number again.

Turn on the pulse motor operation flag.

In step A14, check the pulse motor operation flag and select O.
If it is N, go to step B1 in Figure 5.

If it turns ON, go back to step A6. In step B1, the pulse motor forward rotation flag is checked.

If the pulse motor operation flag is switched from OFF to ON and the step B1 is first reached, the forward rotation flag of the motor is always turned ON in the As step, so the process moves to step B2. That is, the rotation direction of the pulse motor 11 is set so that the dial 12 rotates clockwise.

B2. In step B3, the dial number data stored in the register in order is converted into the number of operation steps of the pulse motor 11. However, in step B2, the pulse motor 11 rotates and rotates the dial 12 until the transmission of one dial data is completed. The B4 step is omitted and the process moves to the B5 step. In step B4, dial data is displayed. In step B5, a signal is output to the transistor group 20 to excite the excitation coil group 19 of the pulse motor 11 in order to rotate the dial 1211F clockwise, and in step B6, this state is maintained for T1 time. Therefore, the pulse motor 11 rotates in the positive direction by one step. In step B7.

The number of operation steps of the pulse motor 11, 8, is decremented. In step B8, it is determined whether the value of the number of days of operation steps decremented in step B7 has become 0, and if it is not 0, the process returns to step A6.

Therefore, when the pulse motor 11 does not operate.

The keyboard is checked repeatedly in A6 steps, and the states of the keyboard 6 and slide switch 8 are read. Also, when the pulse motor 11 operates, the pulse motor 11 is operated by one step angle B5. Step B6 and step A6, which reads the states of the keyboard 6 and slide switch 8, are executed alternately so that the key states can be input at any time. At step B8, if the number of operation steps 8 of the pulse motor 9 is 0, the process moves to step B9.The pulse motor forward rotation flag is turned OFF and the process returns to step A6.

That is, the fact that the pulse motor 11 has rotated by an S step angle means that the dial 12 has rotated clockwise by an angle corresponding to the dial number. Therefore, in order to send the dial signal normally to the same type of telephone, the dial 12 should be rotated in the reverse direction by the pulse motor 11 so that the dial 12 returns at the same speed as the return speed due to the force of the built-in spring. good. Therefore, from B1 step to B
Moving on to step 10, the pulse motor 11 is rotated in reverse until the stop switch 15 is turned on, and its operation will be explained next.

In step B10, a signal is output to the transistor 20 to excite the excitation coil group 19 of the pulse motor 11 so as to rotate the pulse motor 11 in the reverse direction. In step B11, the signal output in step B10 is maintained for 72 hours. At step B12, if the stop switch 15 is ON, the process goes to step B13, and if it is OFF, the process returns to step A6. That is, the pulse motor 11 rotates in reverse until the stop switch 3P switch 15 is turned on.

The rotation speed is determined by the waiting time T2 of step B11, which determines the pulse width of one step applied to the excitation coil group 19.

At B15 step, dial 12 at B12 step.
It was determined that the has returned to its initial position.

A signal is output to turn off all the transistor groups 20, and all 19 excitation coil groups of the pulse motor 11 are turned off.
do. That is, the dial 12 is rotated by the rotational operation of the Tibars motor 11, and the first dialed number stored in the register is output to the telephone line.

At B14, the next dial number stored in the register is checked, and if the dial number is stored, the pulse motor forward rotation flag of step A5 is turned on, and the process moves to step A6. If the dial number is not memorized, move to step B15. B14. A5゜A6.・・・・・・・・・
・A14, B1 steps are executed, and in the second B2 step, it is determined that the data is new and the process moves to B3 step, where the new dial number data is sent to the pulse motor 11.
Convert to the number of operation steps S.

4 Display the dial number data for F, then B5,
B6. B7. Repeat step B8 and rotate the dial 12 to the angle corresponding to the dial number, then step B10. B11. B Repeat step 12 to return dial 12 to its initial position. By repeating these operations, the dial number data sequentially stored in the register is converted into a rotational operation of the pulse motor 11, and the dial 12 is turned.

In step B15, set the waiting time T3, and
If the time has elapsed, return to step A69. After T3 time has elapsed, move to step B16. Step B16 means that all the dial numbers stored in the register are sent to the telephone line by rotating the dial 12, so the contents stored in the register are the phone number of one customer, and the 9th step is to press the redial key. Move Voice/Ta to the beginning so that the memory contents of are dialed in order again, and press B.
The register is dialed sequentially from the beginning in two steps. In step B17, the pulse motor operation 7 is turned off. The display disappears at step B18.

Return to step A5.

In the above description, one function of appropriately dialing a telephone number designated by the numeric keys of the keyboard 6 will be explained in more detail with reference to FIG. 6. K6
In the figure (transformation), if you first enter 10' on the numeric key,
Rotate the dial 12 to the angle corresponding to the lO' number. That is, the pulse motor 11 is rotated forward for a time tt. Thereafter, the pulse motor 11 is reversely rotated at a constant speed for a time t2, and the dial 12 is returned to its rest position. then 17
If you input 13' on the numeric key after the time, the dial 12 will be rotated in the same way to the angle corresponding to the 13' digit, then rotated in the opposite direction at a constant speed for t4, and the dial 12 will be
return to rest position. The above operation is shown in the relationship between the elapsed time and the rotation angle of the dial as shown in Figure 7. The broken line in the figure is the rotation speed at which the dial 12 returns to its rest position when it is rotated with a finger and released, which corresponds to the rotation speed of the dial 120 driven by the motor 11. By the way, as shown in Figure 6 (turn), after dialing "O", press the time numeric key 5 at t' and dial 1.
2 is operated, but if t' is smaller than the waiting time T3 of step B15 in Fig. 5, 'O"l 3#...
If you press the ``Redial'' key to dial the same number again when 9 is busy, dial 12 as shown in Figure 6 (G).
make it work.

However, in FIG.
’, if t” is greater than T3, B in Figure 5
To move from step 15 to step B16,
The number 5 will be stored at the beginning of the register. Therefore, the next time you press the 'redial' key, '3' will be dialed first, and then '3' will be dialed as shown in Figure 6-4.
0' is ignored.

By providing a certain waiting time T5 as described above, when entering the other party's telephone number from the keyboard 6, the dial 1
If the dial 12 is turned back while the 2 dial is turning and the 7 P is entered within 13 hours, you will definitely be able to call the other party. If you leave the interval longer than that, the call will be cut off with a busy tone, so if there is no input for more than T3 hours, the phone number entered from the 9th call will be stored as a new number, making it more reasonable.

As is clear from the above embodiments, the automatic dialing device according to the present invention uses an electric motor such as a pulse motor to rotate the dial of a telephone to automatically dial. Simply set up the device, no tedious construction work is required, and it is easy to install and remove. Furthermore, by connecting the dial driving device and the control device via a connection line and separating them, the control device can be hung on a wall if the space for placing the telephone is limited. at the same time.

Because the only part connected to the telephone is the dial driver, it can be made smaller and lighter.

Furthermore, it is easy to install and remove.
