The present invention is described in detail by the accompanying drawings as follows.

In FIG. 1, the charge separating accommodation device 1 is composed of a cabinet 2 that becomes a box shape. The lower part of the cabinet 2 is constructed of a magnetic material 3 so as to be fixed to a predetermined position of the vehicle. A predetermined position inside the cabinet 2 is provided with a solenoid TH ₁ that blocks the reed switch SW ₁ and the intermediate door. The pedestal 4, which is fixed at a predetermined position of the vehicle in order to fix the cabinet 2, has one or more magnets 8. Therefore, the tariff separator 1 can be firmly fixed by this magnet 5.

The capacitor C ' ₂ is for removing ripple. Therefore, when mounting the charge separation storage device 1 on the base 4, the reed switch SW ₁ interlocked with the magnet 5 is turned on so that the solenoid TH ₁ opens the intermediate door. On the contrary, when the charge separating and storage device 1 is detached from the pedestal 4, the reed switch SW ₁ is turned off so that the transistors TR ₁ and TR ₂ are sequentially turned on to operate the solenoid TH ₁ . The door will be shielded.

At this time, the solenoid 7 'operates only about the charging current of the capacitor C ₁ .

On the other hand, the charge separation storage circuit, which is a safety device and not only separates the storage charge but also emits a warning sound when a bad coin or a foreign substance is inputted, has two mirrors (1) and one on the charge entrance of the charge separation receiver as shown in FIG. (8) are provided so as to face each other at a predetermined distance from each other, and the infrared light emitting element BD ₁ is fixed at one end thereof, and the infrared light receiving element BT ₁ is fixed at the other end thereof.

Therefore, in the charge receiving circuit of FIG. 3, the infrared light emitting device BD _{1 is} connected to the transistors TR ₁ and TR ₂ which become Darlington amplifiers via a resistor R ₁ and constitutes an infrared ray generator 10. . This infrared ray generator 10 is connected to an oscillator 20 which generates a predetermined infrared frequency by the resistor R ₂ .

The infrared oscillator unit 20 is connected in parallel with NOT gates G ₁ and G ' ₁ connected in series, NOT gate G ₂ , and resistor R ₃ , in parallel with a resistor R ₄ and a diode D ₁ . It consists of a connected oscillator. Capacitor C ₁ has a natural frequency with resistor R ₂ . In this oscillator section 20, a signal of a predetermined oscillation frequency, for example, 8192 kHz is generated, and this signal is input to the infrared generator section 10, so that the infrared rays having the wavelength of the oscillation frequency are amplified and emit light (BD _1). Is generated by

The output of the oscillator section 20 is input to the comparator section 30 via the NOT gate G ₃ and to the buffer IC ₃ of the bell drive section 80 described later.

On the other hand, the infrared ray of the light emitting element BD ₁ is refracted at a predetermined wavelength and is applied to the light receiving element BT _{1 as} shown in FIG. The light receiving element BT ₁ operates according to the reception wavelength frequency to oscillate.

The light receiving element BT ₁ is composed of an infrared receiver 40 connected with a resistor R ₁ and a condenser G _{4 to a} collector thereof and a signal of a predetermined frequency is generated and output according to its operation. The signal of the infrared receiver 40 is applied to the first stage amplifier A of the amplifier 50. The amplifier A is connected to a variable resistor R ₁₃ serving as a feedback resistor at its output and input terminals. The signal amplified by this first stage amplifier (A) is applied to the second stage amplifier (B) via the condenser (C ₅ ), and this amplifier (B) also amplifies again, in parallel between its input and output terminals. The furnace resistor (R ₁₅ ) and capacitor (C ₅ ) are negative. The ground terminals of the amplifiers A and B of FIG. 1 and FIG. 2 are commonly connected and connected in parallel with the resistor R ₁₄ , the ground resistor R ₁₆ , and the capacitor C ₇ .

The capacitor C ₈ is a grounding capacitor for ripple cancellation. Thus, the amplifier 50 is configured, and the amplified signal from the amplifier 50 is waveform-formed by the Schmitt trigger unit 60 via the capacitor C ₉ .

In the Schmitt trigger unit 60, an amplified signal is applied to the base of the transistor TR ₆ via the variable resistor R ₁₇ , the resistor R ₁₉ , and the capacitor C ₁₀ . Here, the resistor R ₁₉ and the capacitor C _{10 apply} a differential pulse to the transistor TR ₆ as a differential circuit. A transistor (TR ₆₎ are emitter tuple power (Vcc) to the resistor (R ₁₉₎ when turned on to his collector as usually boring is connected to a resistor (R ₁₉₎ is, via a capacitor (C ₁₁₎ NOT gate (G ₄₎ Is approved. This NOT gate G ₄ is connected to the reset terminal MR of the counter IC ₄ of the comparator section 30.

The comparator section 30 is composed of a counter IC ₄ and a NOT gate G ₅ , the terminal Q _{7 of} which is connected to a NOT gate G ₅ and the terminal Q _{14 of} 2 is described later.

Therefore, the signal amplified via the amplifier 50 is applied to the Schmitt trigger unit 60 to shape the waveform.

Thus, if during normal operation that is, rates in this case are not introduced into the slot oscillation signal from the oscillation unit 20 and the count of the comparison unit (30) includes his terminal (Q ₇₎ and (Q _7), to help separate the 4a waveform but it outputs the same signal, wherein the Schmitt trigger 60 from the circuit signal is, the same oscillating signal to the reset terminal (MR) of the counter (IC ₄₎ enter the counter (IC ₄₎ as to help the 4b degrees waveform Li In this state, no signal is output to the motor driver 70 or the bell driver 80.

However, if a coin or the like is inserted between the mirrors (A) and (B) of the inlet, the infrared signal is cut off at that moment and the signal is not supplied to the reset terminal MR of the counter IC _{4 for} that time. IC ₄ ) outputs a predetermined signal from the terminal Q ₇ by counting it as a reference signal, and activates the timer IC ₅ of the motor driver 70. Since the timer IC ₅ turns on the transistor TR ₂ by a pulse having a predetermined delay time, the motor M is driven to separately insert a coin into the inlet. Here, although not shown in the drawing to be separated according to the amount of coins is generated an infrared cut waveform according to the size of the coin, this waveform appears as a waveform having a predetermined delay applied to the Schmitt trigger unit 60 In the state in which the conveyor belt, which is interlocked with the motor M, is moved based on a predetermined delay time, the coin is separated.

In addition, if the coin is defective or foreign matter is between the mirrors (a) and (b), the counter IC ₄ counts more than the reference signal and applies the output Q ₄ to the flip-flop IC ₆ . ) Will beep.

Then, when the bad coin is removed, the buffer IC ₃ compares the reference signal with the received signal, and applies its output Q _A to the reset terminal RESET of the flip-flop IC ₆ , thereby beeping the bell b. To stop.

As described above, the present invention relates to a charge separation storage device having a safety device to automatically charge the charge and emit a warning sound when a bad coin or a foreign material is inserted.
