JPS63207263A - Public telephone set - Google Patents

Abstract

PURPOSE:To issue a receipt to a user and to improve the serviceability for the user by calculating the information of the fee for a telephone call by calcu lating the traffic and printing out this information when the user originates the call from a public telephone set. CONSTITUTION:When the user hooks off a receiver, a micro-processor 1 reads a number from a push-button part 4 through an input/output port 11 and stores it in a dial number storage part 21 and sends a PB code to an exchange. When the other party responds and calling is started, a charge signal is sent from the exchange to a subscriber's line 7 at the fixed intervals during the service, and the microprocessor 1 scans the charge signal detecting part 6 through an input/output port 13 to control the reception of the fee and meters the message rate to store it in a message rate storage part 22; and when the calling is termi nated, the calculated and received fee is printed out by a printer 9 together with the number of the other party in the dial number storage part 21 in accor dance with a prescribed format.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a public telephone.

[Conventional technology]

Conventional public telephones simply transmit a coin storage signal every time a user drops a coin, and the coin storage frequency meter that receives this signal registers the call frequency.

[Problem that the invention seeks to solve]

The conventional public telephones mentioned above do not issue collection notices for collected call charges, so for example, when you use a public telephone for company or business purposes, you need proof to bill the call charges to a third party such as a company. Also, there is a lack of record keeping for aggregating usage fees.

[Means for solving problems]

The public telephone of the present invention includes a call frequency accumulating means for storing the call frequency, and during a call, calculates the call frequency from a billing signal transmitted from an exchange and outputs it to the call frequency accumulating means, and before the end of the call. The device has a microprocessor that calculates a call charge from the number of calls stored in the call number storage means, converts it into a character code for a printer, and outputs it, and a printing means that prints out the output of the microprocessor.

(Function) In this way, when a call is made, the number of calls is registered and accumulated, and when the call ends, the call charge calculated from the accumulated number of calls is printed out, and a notice of collection of the call charge is issued to the user. can be written.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of a public telephone according to the present invention.

The public telephone of this embodiment is of the push-button dial type, including a hook section 3, a push-button section 4, a PB signal sending section 5 that sends the dialed number to the exchange, and a billing signal detection section 6 that detects billing signals from the exchange. In addition to the subscriber line 7, a memory 2 includes a microprocessor 1 for controlling operations, a dialed number storage section 21 for storing dialed numbers, and a call frequency storage section 22 for storing dialed numbers.
, a printer control unit 8 and a printer unit that print out the destination number and collection charges, and a turnout board 10 to 1 that input and output data between the microprocessor 1 and each unit.
It has 3. Further, the input/output board 10, the printer control section 8, and the printer 9 constitute a printing device 14.

The microprocessor 1 periodically scans the state of the hook unit 3 via the input/output port 11, and when the user picks up the handset and detects off-hook, the microprocessor 1 clears the dial number storage unit 21 and the call frequency storage unit 22. After that, the process moves on to scanning the bush button section 4 via the input/output port 11 and the billing signal detection section 6 via the input/output port 13. Next, when the user operates the button to dial the destination phone number, the microprocessor 1
The number is read from the pushbutton unit 4 via the dial number storage unit 21 via the dial number storage unit 21, and at the same time, the number is output to the input/output port 12.
sends the PB code through subscriber line 7 to an exchange (not shown). When the other party answers and the call begins, during the call,
Since billing signals are sent from the exchange to the subscriber line 7 at regular intervals, the microprocessor 1 detects the billing signal detection unit 6.
is scanned via the input/output port 13, and as a result, when a billing signal is detected, charge collection control is performed, and the number of calls is registered, and the number of calls is stored in the call number storage section 22.
Remember it. At the end of the call, when the microprocessor 1 detects that the hook unit 3 is on-hook via the input/output boat 11, the microprocessor 1 calculates the call fee calculated from the call rate stored in the call rate storage unit 22 of the memory 2 and stores it in the dial number. Together with the destination number of the loading section 21, it is converted into a character code for the printer according to a predetermined format and sent to the printer control section 8 via the input/output boat 10, which causes the printer 9 to print out the destination number and the collected charge. .

At this time, when installing the telephone, by adding a read-only memory that can permanently store the telephone number of the telephone and an @ number setting switch, it is possible to add the telephone number of the calling public telephone and a clock. It is also possible to print out the date and time of use together with the above-mentioned destination number and collection fee.

〔Effect of the invention〕

As explained above, in the present invention, when a user makes a call from a public telephone, a collection notice can be issued to the user by registering the number of calls, calculating the call charge information, and printing it out. This has the effect of improving service to users.
