Abstract

PURPOSE:To automatically switch to an action with a automatic dialling system when a call card is consumed by providing a call card completion detection means to detect the completion of the call control by the call card. CONSTITUTION:When it is discriminated that a call card 4 is put into a processor 3, the discrimination of whether the call is possible or not is executed by the said card. This discrimination is executed by whether or not a call frequency stored in the call card 4 remain available. When a hand set is returned and a call completion is discriminated, the call control is finished. When the card is not put into or the call by the card is impossible, namely no frequency is left in the card, the call is automatically switched to the condition of an ordinary automatic dialling action in response to a call card completion output signal.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a call control device that is coupled to a telephone such as a home telephone using an automatic dialing system and is used to control calls of the telephone.

In particular, the present invention relates to a call control device for an automatic dialing telephone that can be used in combination with a calling card called a telephone car.

SUMMARY OF THE INVENTION This invention enables a telephone with an automatic dialing system to be used with a calling card in which the number of possible calls is stored, and in this case, a calling card priority means is provided for preferentially using the calling card. By providing a calling card end detection means for detecting the end of call control by the calling card, when the calling card is used up, the operation is automatically switched to the automatic dialing method, so that continuous calls can be made. This is what I did.

Regarding public telephones that can be used with conventional technology calling cards and coins,
Jikai No. 59-208973 or JP-A-61-154
There is one shown in No. 255. In ordinary public telephones, if a calling card and coins are used at the same time, the calling card is used preferentially. Then, during the same call, when the number of calls that can be made using the card has expired, the presence or absence of coins is detected for K, and the call is automatically switched to a call using coins.

Problems to be Solved by the Invention These days, we live in a calling card society, and it has become common to use calling cards when using public telephones. These calling cards are not only commercially available, but also come in various forms as gifts.

If you use these calling cards only from external public telephones, you will not be able to use them all and end up with a number of calling cards sitting on your desk at home or in the office, which is not only very uneconomical, but also makes it difficult to use the calling cards. It also hinders its use. If such a calling card could be used with a regular telephone at home or in the office, it would be very economical, and further use of the calling card could be expected.

Further savings in telephone charges can be expected by providing such calling cards to children at home. The present invention aims to provide a call control device for a telephone that allows a user to effectively utilize a call card as described above.

Means for Solving the Problems The present invention provides a control device for controlling telephone calls based on a calling card storing the number of possible calls and an automatic dialing operation. (including) discriminating means for discriminating that the calling card is being used for the call control in response to the output of the discriminating means; a calling card priority means for preferentially using the calling card in response to the output of the determining means for the call control; and termination of the call control using the calling card. A call control device for a telephone, comprising: a calling card end detection means for detecting a calling card end; and means for automatically switching a call to an automatic dialing state in response to an output of the calling card end means. be.

When it is determined that the active calling card is inserted, the calling card is used preferentially by the means for preferentially using the calling card. Then, the number of possible calls stored in the call card is used on a continual basis. When the number of possible calls stored in the calling card is fully used, the call is automatically switched to an automatic dialing state. The number of times stored in the calling card and the number of times actually used are compared and calculated, and the remaining number of times is written anew to the calling card. Further, when all the number of times stored in the calling card have been used, an expiry display is displayed, indicating that the call has been switched to automatic dialing and that the calling card can no longer be used.

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

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. In this embodiment, a telephone main body 1 includes a data processing device 2 and a card processing device 3, and the card processing device 3 is provided with a calling card insertion slot 5 into which a company calling card 4 is inserted. The calling card 4 is a commonly available card. The data processing device 2 and the card processing device 3 function to read the number of calls on the inserted calling card and erase the number of calls on the calling card by the number of calls not used for the call. When the calling card 4 is inserted into the card insertion slot 5 and the handset 6 of the telephone main body 1 is picked up by the user to start a call, the data processing device 2 first determines whether the calling card 4 is inserted or not. Make a determination. This is indicated as step S1 in FIG. The same applies hereafter. When it is determined that the calling card 4 is inserted into the card processing device 3, it is determined whether or not it is possible to make a call using the card (step s2). This determination is made based on whether or not there is a number of calls stored in the call card 4. If it is possible to make a call, in step S3, the amount of one call, that is, the number of calls is subtracted from the data stored in the card. If the call ends within one call time, steps S1, S2, S3, S4 and S5 are repeated. Then, in step S4, the handset 6 is returned, and when it is determined that the call has ended, the call control is ended.

If no card is inserted in step S1,
Alternatively, in step S2, if it is not possible to make a call using the card, that is, if there are no more calls left on the card, the process advances to step S7. In step S7, the call is automatically switched to a normal automatic dialing state in response to the calling card termination output signal. Immediately after switching to the normal automatic dialing mode, a first call request is registered via the telephone line 8 with the master controller of the telegraph and telephone company shown in the drawing, by the means used during normal calls. Ru. Even if the number of times stored in the calling card has not expired, the calling card 4
The same operation occurs when the card is pulled out from the card insertion slot 5. When the number of calls allowed on the calling card has expired, an expiry indication is displayed on the lamp 7 provided on the telephone main body 1 in step S6. At this time, you may remove the current card and insert the next card.1. In this embodiment, a data processing device 2 and a card processing device 3 are provided in the telephone main body 1.
However, it is easy to understand that the same function can be achieved even if these are housed in a dedicated device separate from a normal telephone and connected via a special attachment. This has the advantage that the telephone currently in use can be used as is.

Furthermore, if the above-mentioned master converter performs the function of the data processing device 2, the manufacturing cost of the telephone will be reduced.

Effects of the Invention As described above, this invention makes it possible to effectively utilize calling cards, which would otherwise be left unused, at home or in the office, which is a great way to save money on telephone charges at home or in the office. This will encourage the further spread of calling cards.

Furthermore, since the present invention can be realized by simply modifying an ordinary telephone, it does not require a large space even if it is installed at home or in an office.
