Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for counting the number of outgoing calls made by a telephone.

Understanding the number of calls made to a specific telephone number and the number of calls made in other cases is important as a means of promoting proper telephone use.

However, this type of simple number-of-call counting device has not been proposed in the past. The present invention aims to solve this problem by displaying, using a microcomputer, etc., how many times calls have been made to frequently used calling telephone numbers and how many times calls have been made to other telephone numbers. The aim is to reduce telephone calls and reduce telephone costs.

The present invention includes a dial signal detector using a pickup coil or the like, a storage device that stores frequently used outgoing phone numbers, a central processing unit that searches whether the outgoing phone number is a phone number in the storage device, and a storage device. It is comprised of a display section that distinguishes between internally originated telephone numbers and externally originated telephone numbers and displays the number of times of outgoing calls.

FIG. 1 is a block diagram showing an embodiment of the present invention, in which the phone number memory 7 stores the area code, local code, number 00044 411 by operating the operation unit 6.
001800003 492 414
As per step 1, set it.

The operation unit 6 is configured so that the user can easily make changes to the telephone number memory, print out the number of outgoing calls, clear the number of outgoing calls memory, etc. The central processing unit 4 is
The dial pulse is constantly scanned through the bus line 3, the calling number is temporarily stored in the calling number memory 8, and the telephone numbers are compared. When a call is made, a dial pulse and a call start signal are detected by a dial signal detector 1 using a non-contact pickup coil, etc., and are waveform-shaped and level-converted by a signal processing section 2. The storage device 12 includes an internal number memory 9 that stores the number of calls made to the telephone number stored in the calling number memory 7, an external number memory 10 that stores the number of calls made in other cases, and a called number memory 10 that temporarily stores the number of calls made. It is composed of a number memory 8 and the like. FIG. 2 is a flowchart for explaining the operation of the number-of-calls counting device according to the present invention.

When the user picks up the handset and starts turning the dial, the central processing unit 4 clears the calling number memory 8. The calling number is arranged in two digits at a time in the signal processing section 2, and stored in the calling number memory 8 in the central processing unit 4 every time two digits are arranged. If the handset is hung up in the middle of dialing, the program memory 1 is programmed to wait until the handset is picked up again and dialing begins. When a call is started, the central processing unit 4 compares the contents of the calling number memory 8 and the contents of the telephone number memory 7, and if the contents match, the stored number of times is increased by 1, and if they do not match, the central processing unit 4 compares the contents of the calling number memory 8 and the telephone number memory 7. , add 1 to the extra memory count memory. Once the number of times memory has been added, the process returns to the state of waiting for dialing to start again. Operation unit 6
By operating the operation start switch at , you can print out the contents of the count memory, clear the contents of the count memory,
It is possible to perform operations such as correcting and printing out the contents of the telephone number memory 7. As described above, according to the present invention, it is now possible to promote proper telephone use by understanding the number of calls made to phone numbers within the pre-stored phone numbers and the number of calls made outside the memory. It is.

If you install this device in a place where outgoing phone numbers are limited, you will not only be able to know the ratio of the number of calls made for public and private purposes, but also be able to set the number of calls in memory for each phone number. This has the effect that it is also possible to know the details of each number.
