JPS5934757A - Coin deposition type recalling telephone set - Google Patents

Abstract

PURPOSE:To attain the automatic recalling with re-deposition of a coin at the cut-off after deposited coins were finished, by providing a means storing a dialed called party number and transmitting the number. CONSTITUTION:Dial information from a number transmitting circuit 12 is given to an exchange 17 when a coin is deposited and the dial operation is performed in a coin deposition type telephone set 10, the connection is made with a called party 18 by the known method and stored in a storage circuit 16. The call with the telephone set 10 is cut off, when no coin is deposited additionally during the call and a prescribed call time is elapsed. In depositing again a coin while hooking off a transmitter-receiver in this state, an off-hook state motor circuit 13 and a coin deposition monitor circuit 14 give a start signal to a network control circuit 15. The network control circuit 15 transmits dial information in the storage circuit 16 to the exchange 17 for attaining retransmission. The stored information in the storage circuit 16 is erased with the off-hook of the transmitter- receiver.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to a coin-loading telephone, and in particular, when a coin-loaded telephone has finished a call for the amount charged, the coin-loading telephone can be used again in an off-hook state.
This invention relates to a coin-insertion type Pi call-and-watch machine that automatically sends out a previously stored called party number upon the first call-making operation by inserting a coin, and controls the conversation.

(1)) Prior Art and Problems Conventionally, with this type of coin-loading telephone, a coin is inserted, the number of the recipient is entered, and a call is made, but the call is about to end due to the amount of coins inserted. If the caller continues the call, the caller inserts the next coin, but the caller fails to put out the 01 coin.In this case, the call is disconnected. Therefore, the caller had to pick up the handset again, insert a coin, and dial. This makes the caller feel extremely anxious and must always be aware of the coin, and when the public is busy, performing the above operation may cause the caller to feel like they are using the coin more than once. There were some drawbacks that made it difficult to use.

(C) Purpose of the Invention The present invention solves the above-mentioned drawbacks of the prior art, and allows the user to insert a coin again after the coin is cut off due to the end of the coin.
To provide a coin insertion type re-calling telephone capable of automatically transmitting a call and a called party number to an exchange.

(d) Overview of the Invention The coin-inserted re-calling telephone Fi of the present invention has a means for storing the telephone number of the called party, and a disconnection signal while remaining in an off-hook state when the call for the amount charged is completed. a means for transmitting a start signal to the exchange upon the insertion of a coin again; and a means for transmitting a memorized telephone number of the called party to the exchange when the exchange enters a digit reception state; By having means for sending a message to the called party, the call is disconnected when the coin ends, and by inserting the coin again, the called party can be automatically called and the call can be made.

(e) Examples of the invention Next, the present invention will be further explained with reference to the drawings.

The figure is a block diagram showing one embodiment of the present invention, and shows only the main parts of the present invention. , coin-operated telephone 1
0 is a public telephone circuit 1 consisting of a number sending circuit 12, an off-hook state monitoring circuit 3, and a coin insertion monitoring circuit 14.
1, and a network control circuit 15 which independently stores and activates the called party's number and sends the dial to the other party.

The operation of the present invention will be explained step by step with reference to the figures below.

When the caller inserts a coin into the coin-operated telephone, the public telephone circuit sends a call instruction to the switching device, which then sends it to the caller, allowing dialing. At this time, the f@ storage circuit 16 is prepared to store the telephone number of the called party. Then, when the calling party dials the called party's number, it is sent to the exchange 17 via the subscriber line 19, and
It is also sent to the number storage circuit 16. The number storage circuit 16 stores the received evaluator's telephone number and performs similar processing up to the last digit. After the caller dials up to the last digit, connection processing to the publicly known telephone number 5-phone machine 18 is performed.
A call can be made by the response from the general telephone machine. The coin insertion type telephone sends a disconnection signal to the exchange and disconnects the call if no additional coins are inserted by means of a coin storage signal or the like. At this point, the handset is off-hook.
It is.

If a coin is inserted again in this off-hook state, the disconnection detection warrant, the off-hook state monitoring circuit 13's off-hook state monitoring circuit 13, and the coin insertion confirmation information of the coin insertion monitoring circuit 14 are used to detect the disconnection. The network control circuit 15, which confirms the dial tone from the exchange material 17, takes out the number of the recipient Nagisada from the number storage circuit 16, engraves it on the exchange 17, and automatically sends it out. .

After all digits have been sent, the network control circuit 15 connects the subscriber line 19 to the public telephone circuit 1, so that the caller can confirm the caller's response with the receiver. In this state, when the called party answers the call, the call can be made.

The call is over! When the handset of the coin-operated telephone is turned on-hook, the off-hook state monitoring circuit 13 notifies the network control circuit 15 of the off-hook state, initializes the network control circuit 15, and stores the number in the number storage circuit. Delete the called name telephone number.

(f) Effects of the Invention As explained above, the present invention allows coins to be inserted into a coin-operated telephone automatically by re-inserting the coins into the coin-operated telephone with the handset still up even after the call for the charge is completed. It has the effect of transmitting and making h'Jσ: crystal possible &'C with the strongest class leader.
