DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of a public telephone according to the present invention. This public telephone has a telephone line L1,
L2 and is configured as follows. That is, 1 is a billing signal receiving circuit for receiving a billing signal arriving at the telephone lines L1 and L2 during a call, 2 is a diode bridge, and 3 is a forced disconnection that cuts off a DC loop of the lines L1 and L2 when a call charge becomes insufficient. Reference numeral 4 denotes a communication circuit, reference numeral 5 denotes a handset, reference numeral 6 denotes a control unit composed of a CPU or the like, reference numeral 7 denotes a coin processing unit for performing processing such as sorting of inserted coins, and reference numeral 8 denotes a display. 9 is a dial key, 10 is a one-touch dial key, 11 is an MF generator that generates a dial signal such as DTMF, and 12 is a unit charge of a service charge when an air conditioner 16 or the like described later is connected. A switch 13 is an air conditioning button for turning on the air conditioner 16,
Reference numeral 4 denotes an interface circuit for interfacing with the air conditioner 16, and reference numeral 15 denotes a power supply circuit for supplying power to each unit of the public telephone.

[0007] The public telephone constructed as described above is disposed in a telephone box, and is connected to an air conditioner 16 similarly disposed in the telephone box and operated by a commercial power supply. When the user goes off-hook and inserts a coin to call the other party, the loop of the lines L1 and L2 is closed, and when the dial number 9 is subsequently operated to dial the other party number, an MF signal is generated. The dial signal is sent from the device 11 to the lines L1 and L2, and as a result, the other party is called. When the call is answered, the call is started, the storage of more deposited coin to the charging signal arriving during a call is carried out. When the telephone box feels hot when talking with the other party, the air-conditioning button 13
When is pressed, the air conditioner 16 is operated via the interface circuit 14 so that the inside of the box can be controlled to have an appropriate temperature.

Next, the operation of the control unit 6 in the public telephone for controlling the air conditioner 16 will be described with reference to the flowchart of FIG. That is, the off-hook of the user is detected in step 100, and the insertion of coins is further performed in step 10.
When the detection is made in step 1, the data is stored and the forced disconnection circuit 3 is controlled to form a loop of the telephone lines L1 and L2 (step 102). When the user operates the dial key 9, a dial transmission process for transmitting a dial signal corresponding to the dial key 9 to the lines L1 and L2 is performed (step 103).

In this case, it is determined in step 104 that the air-conditioning button 13 has been pressed, and if this air-conditioning button 13 has been pressed, the flow proceeds to step 105 to determine the remaining amount of the accumulated coins. In this case, the sum of the air-conditioner usage fee per unit time and the call fee for one call is determined as the remaining coin amount. If "Y" is determined in step 105, coins per unit time of the air conditioner determined by the service charge setting switch 12 are stored (step 106), and a drive signal ON is sent to the interface circuit 14. The air conditioner 16 is operated (Step 107). Thereafter, a timer for a predetermined time is started (step 108), and at the same time as step 10
After "N" of the time-up of the timer in step 9, it is determined in step 110 whether the charging signal has been received. Also, when the depression of the air-conditioning button 13 is not detected and the answer is “N” in the step 104, the process shifts to the step 110.

At step 110, it is determined whether a billing signal arrives at the lines L1 and L2, and if a billing signal is received, it is then determined at step 111 that there is a remaining coin.
If there is a remaining coin, the coin corresponding to one call is stored (step 112), and the on-hook in step 113 is determined. Also, when the billing signal has not arrived, the on-hook in step 113 is similarly determined. However, if the caller's call is continuing, step 113
Is "N", and in this case, step 11
After determining that the air conditioner 16 is operating in step 4, if the air conditioner 16 is not operating, the process returns to step 104 to detect the pressing of the air conditioning button 13, and if the air conditioner 13 is operating, the process proceeds to step 109. Then, the time-up of the timer already started in step 108 is detected.

In this case, the timer of the predetermined time has expired, and if "Y" is determined in step 109, the process returns to step 105 to determine again that there is a remaining coin. And the operation of the air conditioner 16 is stopped (step 11).
5) Then, it is determined whether or not the billing signal has been received in step 110. If the billing signal arrives and there are no more coins to be stored while the call is continuing (step 1)
In the case of "N" in 11) and the case of ending the call by on-hook (in the case of "Y" in step 113), the forced disconnection circuit 3 is controlled to release the loop of the lines L1, L2 (step 120). At the same time, the operation of the air conditioner 13 is checked in step 121, and if it is in operation, the operation of the air conditioner 13 is stopped after the timer expires, and the operation is terminated (steps 122 and 12).
3).

As described above, when the air conditioner 13 is operated during a call, the call charge is stored according to the billing signal, and the usage charge of the air conditioner 13 is stored at predetermined time intervals. . However, in this case, the call is given priority,
Even when the usage fee of the air conditioner 13 is insufficient, the operation of the air conditioner 13 is only stopped to allow the continuation of the call. In addition, this public telephone is not limited to the air conditioning service described above,
For example, in the case where various services are received from the other party by operating the one-touch dial key 10 to make a memory dial call registered in advance, the service charge and the call charge can be collected independently.

[0013]

[Effects of the Invention] As described above, according to the present invention,
When a billing signal arrives during the provision of a call service ,
While storing the unit call charges from the charges, the air conditioner is activated.
When activated, a predetermined amount of charges from the accumulated charges is air-conditioned.
Because it has to be stored as machine usage fee, this air conditioning
It becomes possible to store the usage fee of the machine together with the call fee.
