Description

[Detailed Description of the Invention] The present invention relates to an in-vehicle television receiver pay system.

Recently, consideration has been given to installing small television receivers in taxis and allowing passengers to watch them for a fee. In this case, the television receiver can be charged a fee using a coin timer. However, the coin timer is turned on for a certain period of time when a predetermined coin is inserted, so if multiple passengers get on and off the taxi one after another, the next passenger will turn on the TV while the coin timer is on due to the previous passenger's coin insertion. Since television receivers can be viewed for free, charging for television receivers becomes unfair and is not good for business.

It is an object of the present invention to provide an in-vehicle television receiver pay system that eliminates the above-mentioned drawbacks and allows customers to view the television receiver fairly for a fee.

The present invention will be described by way of embodiments with reference to the drawings.

FIG. 1 shows the external connections of an embodiment of the present invention. This in-vehicle television receiver pay device 1
1 is supplied with power from a power source 12 consisting of an automobile battery, and controls the power of an in-vehicle television receiver 13 installed in a taxi. In a taxi, when the taxi is empty, the fare meter is turned over to turn on the empty car lamp 14, and the empty car lamp lighting signal is inputted to the in-vehicle television receiver tolling device 11 as a reset signal.

FIG. 2 shows this in-vehicle television receiver pay system 11. As shown in FIG. The coin validation section 15 is a mechanical section having a coin input slot and a return slot, and sorts the coins inserted by the customer from the coin slot into genuine coins and foreign coins, and sends the coins of different types to the return slot. Here, the specie coin is a predetermined coin, and the foreign coin is something different. The genuine coin detection section 16 detects whether there is a predetermined number of genuine coins classified by the coin verification section 15, for example, one coin. R-S
A storage unit 17 consisting of a flip-flop is set by a genuine coin detection signal from the genuine coin detection unit 16,
It is reset by the reset signal (empty vehicle lamp lighting signal). When the storage section 17 is in the set state, the load control section 18 closes the point 19 based on the output signal of the storage section 17 to close the point 19 of the in-vehicle television receiver 1.
By connecting the power supply terminal 3 to the power supply 12, viewing on the television receiver 13 is enabled. Therefore, when a customer inserts a predetermined coin into the coin slot of the coin verification section 15, the television receiver 13 becomes available for viewing, and when the customer gets off the train and the empty car lamp 14 lights up, the television receiver 13 is turned on. The power goes out and you can't watch it.

FIG. 3 is a circuit diagram specifically showing the vehicle-mounted television receiver toll device 11. As shown in FIG. In the figure,
Q ₁ to _{Q 3} are transistors, PC1 is a photocoupler,
NA1 and NA2 are NAND circuits that constitute the RS type flip-flop FF, N is an inverter, RY is a relay with a normally open contact RY-a, _C1 and _C2 are capacitors, _R1 to _R8 are resistors, and _D1 is a diode. , +V _IN is the power input terminal connected to the power supply 12, GND is the grounding terminal, RESET is the reset terminal to which the above reset signal is input, and OUT is the television receiver 13.
This is the power output terminal connected to the power supply terminal.

The photocoupler PC1 constitutes a specie detection unit 16,
A genuine coin from the coin verification section 15 is detected when the coin is inserted, and a flip-flop FF is set. This flip-flop FF constitutes the storage section 17,
It is reset by turning on transistor _Q1 with a reset signal. When flip-flop FF is set, transistors Q ₂ and Q ₃ are turned on, relay RY is activated, and its normally open contact RY-a is activated.
(constituting the contact 19) is closed and the television receiver 13 is powered on.

As described above, in the in-vehicle television receiver pay system according to the present invention, viewing is enabled by inserting a predetermined coin into the in-vehicle television receiver, and viewing is automatically disabled when the empty car lamp is lit.
This is effective for business as it allows customers to watch on a car-mounted television receiver fairly for a fee without having to watch for free.
