Description

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

[Prior Art] Conventional public telephones store coins in response to a coin collection signal from the telephone office, and use a distance-based time difference system in which call charges vary depending on the distance of the call. The above-mentioned coin storage signal is not supplied to ordinary households, and conventional telephones for ordinary households can be used without inserting coins.

[Problem to be solved] Conventional telephones for general households do not accept coins, so
In many cases, people end up making long phone calls without thinking about the call charges. It is also easy for young children to make phone calls by mistake.

An object of the present invention is to provide a coin-loading telephone for general households.

Means for Solving the 1st Division Problem] The present invention provides a coin determination circuit that determines whether a coin has been inserted into a coin slot, and a timer circuit that starts timing at the same time as a call starts and generates an output after a certain period of time. and a line connection control circuit which becomes in a state in which transmission is disabled by the output of this timer circuit, and becomes in a state in which transmission is possible when the above-mentioned coin determination circuit determines that a correct coin has been inserted in the off-hook state. It is something that solves problems. Furthermore, by providing an amount counting circuit for counting the total amount of coins that have been determined to be correct coins and received by the coin determining circuit, and a display section for displaying the amount counted by this amount counting circuit,
It is convenient to see the total amount of stored coins at a glance.

[Example] Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the drawing, 1 is a telephone line, 2 is a dial for transmitting a telephone number, 3 is a communication circuit, 4 is a handset, and 5 is a hook switch for switching the connection between the telephone line 1 and the communication circuit 3. Reference numeral 6 designates a coin determination circuit for identifying and determining the coin inserted into the coin slot, 7 a gate circuit, and 8 a response detection circuit for detecting a response to transmission. 9 is a gate circuit; lO is a timer circuit that starts counting when a response is detected by the response detection circuit 8 in the off-hook state and generates an output after a certain period of time; 11 is a timer circuit that detects the correct coin by the coin determination circuit 6 in the off-hook state. This is a line connection control circuit that enters a transmittable state when it is determined that the line has been turned on, and becomes a transmittable state in response to a time-up signal from the timer circuit 10. 12 is an inverter circuit; 13 is a refund solenoid circuit that refunds coins inserted when the hook switch 5 is in the on-hook state and coins that are determined to be incorrect by the coin determination circuit 6; and 14, a timer circuit 10 for starting timing. A receipt solenoid circuit stores the correct coins inserted at the same time into the storage box, and 15 is an amount counting circuit that counts the total amount of coins stored in the storage box. 16 is a display selection circuit for selecting whether to display the time measured by the timer circuit 10 or the amount counted by the amount counting circuit 15;
17 is a display unit that displays the content selected by the display selection circuit 16; 18 is a display unit that displays the content selected by the display selection circuit 16;
This is a reminder sound generation circuit that generates a reminder sound from.

Next, the operation will be explained. When making a call, first set the hook switch 5 to the off-hook state, and then the gate circuit 7
, 9 are output. Next, a coin is inserted into the coin slot, and when the inserted coin is judged to be correct by the coin judgment circuit 6, a signal is output to the gate circuit 7, an output is generated from the gate circuit 7, and the line is connected. A signal is supplied to the control circuit 11, and this signal connects the telephone line 1 and the communication circuit 3 to enable transmission.

When the above operation enables transmission, dial 2 to send the telephone number. When the other party responds to this call and the other party's hook switch is placed in the off-hook state, this is detected by the response detection circuit 8, a signal is output to the gate circuit 9, an output is generated from the gate circuit 9, and the timer circuit 1
A signal is supplied to o. This signal causes timer circuit 1o
At the same time as the coin starts counting, a signal is output to the cash receiving solenoid circuit 14, and one inserted coin is stored in the storage box. As the call time elapses, coins are stored one by one in the storage box, and the total amount is counted by the amount counting circuit 15. The display selection circuit 16 selectively outputs either the signal from the timer circuit 10 or the signal from the amount counting circuit 15 to the display section 17, and based on this signal, the display section 17 shows the timer circuit 10 measuring time. Either the current time or the total amount of coins in the storage box counted by the amount counting circuit 15 is displayed.

When the timer circuit 10 measures a predetermined time, it outputs a signal to the reminder sound generation circuit 18 and the coin determination circuit 6. In response to this signal, the reminder sound generation circuit 18 outputs a reminder sound generation signal to the handset 4, and the handset 4 generates a reminder sound. For example, assume that you can make a call for 3 minutes with 1l of 10 yen, and when 2 minutes and 30 seconds have passed from the start of the call, the handset 4 will emit a reminder sound saying "Pila." This notifies the caller that the available talk time has ended. If no additional coin is inserted at this time and the timer circuit 10 measures 3 minutes, the timer circuit 10 sends the line connection control circuit 1 to the line connection control circuit 1.
A signal is output to the telephone line 1, and this signal brings the telephone line 1 and the telephone call circuit 3 into a non-conducting state, thereby terminating the telephone call. on the other hand,
When an additional coin is inserted before the timer circuit 10 measures 3 minutes and the coin determination circuit 6 determines that the coin is correct, a signal is output from the coin determination circuit 6 to the timer circuit 10. This signal causes the timer circuit 10
As soon as the clock finishes counting three minutes, it starts counting again, and no signal is output to the line connection control circuit 11. Therefore, the call state can be continued.

When a call is received, the call can be made in the same way as a conventional home telephone, regardless of whether coins are inserted or not, and regardless of the timer.

With the above operation, when making a call, the phone is enabled to make a call for a period of time corresponding to the number of coins inserted.

If the hook switch 5 is in the on-hook state when the coin is inserted, the signal is inverted by the inverter circuit 12, the refund solenoid circuit 13 is activated, the coin is refunded, and it is not possible to make a call.

In addition, in the above example, 1l of 10 yen can be used to talk for 3 minutes, but it is not limited to this.Multiple types of coins can be used, and the call time can change depending on the type of coin inserted. Good too.

In addition, in the Niki example, a reminder tone was generated before the end of the available talk time, but this is not the only option. You can also do this.

[Effects] According to the present invention, when making a call in a general home telephone, a coin must be inserted2, and the time during which a call can be made using one coin is determined in advance. Therefore, the longer the call time, the more coins are required, which helps prevent long phone calls.

Furthermore, since the phone cannot be used unless a coin is inserted, there is no chance that a child or the like will accidentally make a call while playing with the phone.
