Abstract

PURPOSE:To relieve the user from troublesome load of dialing in a public telephone set by selecting any of subscriber telephone numbers written in a subscriber card and sending a dial pulse of the subscriber telephone number automatically. CONSTITUTION:A talking section 2 of a public telephone set 1 is connected to an exchange 6 of a station and a magnetic card 7 is loaded to a card unit section 4. A control section 5 identifies whether the card 7 read by the unit section 4 is a magnetic card written with a call number data or a subscriber card being a magnetic card written is a subscriber telephone number. In case of the subscriber card loaded, an abbreviation code from a user is received and the subscriber number is selected. In receiving a deposited coin, the selected subscriber telephone number is sent automatically as a dial pulse. Thus, subscribers are connected and the talking is attained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a magnetic card type public telephone that uses a magnetic card to make a call. This invention relates to a magnetic card type public telephone that can automatically dial subscriber numbers that are currently available.

[Conventional technology]

With the advancement of semiconductor technology, a wide variety of public telephone services have become available. In particular, when electronic switching equipment built using large numbers of large-scale integrated circuit processors became commercially available, switching technology developed dramatically and a variety of services began to be provided. Ta. That is, telephone exchange services such as speed dialing, forwarding services, and answering machines, as well as communication services such as data communication and image communication, are being provided one after another. Semiconductor technology is
This has had a major impact not only on electronic exchanges that utilize computer program control technology, but also on the way telephones are used. That is, the advent of magnetic card type public telephones. By storing information about call charges on the magnetic card, that is, the number of times you can make calls, you can gift the magnetic card to each other as if it were a gift certificate. You can make calls with peace of mind even when you don't have any coins or when you don't have enough coins.

Now, when making a call using a magnetic card, follow the steps below. Remove the handset and insert the magnetic card into the slot at the top center of the phone. After you hear the dial tone, specify the other party's phone number and make the call. When the call ends and you put the handset back on, the magnetic card comes out from the bottom center of the phone. The number of times the magnetic card can make calls is displayed on the top left side of the phone, so when this number gets low, insert a 100 yen coin into the slot on the top right side of the phone. Just leave it there.

[Problems that the invention is supposed to solve]

In conventional magnetic card type public telephones, a magnetic card is used as a substitute for coins for making calls. Therefore, like a general public telephone, the telephone number of the other party must be dialed in sequence, and it is not possible to register the subscriber's telephone number by speed dialing using the telephone itself, as is the case with a general subscription telephone. Therefore, it is necessary to write down all the telephone numbers of the other party in a notebook and carry the notebook with you at all times, especially when making a long distance call. Dialing can sometimes result in incorrect dialing, which lacks convenience.

[Means for solving problems]

The present invention provides identification means for identifying whether an inserted magnetic card is a calling card, which is a magnetic card on which frequency data is written, or a subscriber card, which is a magnetic card on which a subscriber's telephone number is written; selection means for selecting one of the subscriber telephone numbers written on the subscriber card when the magnetic card is a subscriber card; and automatically sending out a dialing pulse for the selected subscriber telephone number. and an automatic dialing pulse sending means.

[Effect]

When a magnetic card is inserted into a telephone, it is identified whether it is a calling card or a subscriber card, and if it is a subscriber card, the subscriber telephone number written on the card is designated by the speed dial registered on the card. The dial pulse is automatically sent out.

〔Example〕

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

FIG. 1 is a block diagram showing the main configuration of this embodiment, and shows only the parts necessary for explanation. A magnetic card type public telephone 1 includes a talking section 2 including a handset, a dial, a dial pulse sending section, etc., a middle board section 3 that sorts and stores inserted coins, and a card unit that feeds and reads magnetic cards. It is composed of a section 4 and a control section 5 that controls each section of the telephone. The public telephone 1 has a talking section 2 connected to a central office exchange 6, and a magnetic card 7 inserted into its card unit section 4. Furthermore, this control section 5 controls whether the magnetic card 7 read by the card unit section 4 is a calling card, which is a magnetic card on which frequency data is written, or a subscriber card, which is a magnetic card on which a subscriber's telephone number is written. an identification means for identifying the user, and a selection means for selecting an arbitrary subscriber telephone number specified by the user through the dial of the telephone part 2 from among the subscriber card data obtained by the identification means; An automatic dial pulse transmitting means is provided for automatically transmitting the subscriber telephone number selected by the selection means via the dial pulse transmitting section of the communication section 2. FIG. 2 shows a subscriber card, and is an example of a magnetic card 7 in which a subscriber's telephone number is registered.

For example, it is assumed that the subscriber number "011111111114" is registered corresponding to the short code r%oOJ.

FIG. 3 shows a schematic flow of magnetic card identification, subscriber telephone number selection, and automatic dialing processing. Processing 10
When the insertion of a magnetic card is detected by the monitoring in step 1, processing 1 is performed.
At step 02, it is determined whether the inserted magnetic card is a calling card or a subscriber card. If the inserted card is a subscriber card, a short code from the user is received in process 103,
In step 104, the subscriber's telephone number is selected using the abbreviated code of the subscriber card entered. For example, if the short code is r%00J, the subscriber's phone number is rollll.
llllllll”. Therefore, in step 105, when a coin is inserted, the subscriber's telephone number selected in step 104 is automatically sent out as a dial pulse. In this way, subscribers are connected and can make phone calls.

In other words, even if the phone is a magnetic card type public telephone, speed dialing can be performed by using a subscriber card.

〔Effect of the invention〕

According to the present invention, in a magnetic card type public telephone using coins, there is an identification means for identifying whether it is a calling card or a subscriber card, and a selection for selecting either the subscriber telephone number written on the subscriber card. Since it is equipped with a means for automatically dialing the subscriber's telephone number and a means for sending out a pulse for automatic dialing of the subscriber's telephone number, it is possible to carry out speed dialing in the same way as with a general subscriber telephone. Once the user is freed from remembering the number,
In addition to exhibiting great effects, the practical effects are also extremely large.
