Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of a sequentially and automatically controlled TV set testing apparatus according to an embodiment of the present invention. The auxiliary power supply means 5, the power supply means 10, the oscillating means 20, the sequential control means 30 A TV setting detecting means 40, a time edge portion 45, a memory means 50, an input means 52 and a TV control signal generating means 60.

The power supply means 10 is constituted by a three-terminal constant voltage integrated circuit 10IC and two capacitors C1 and C2. The input terminal 1 of the constant voltage integrated circuit 10IC is supplied with AC power, And the DC power source 12V necessary for the circuit operation of the present invention is output to the power source circuit 3 of the present invention. The two capacitors C1 and C2 are connected to each other by the oscillation by the drive of the integrated circuit 10IC And is connected to the input terminal and the output terminal of the integrated circuit 10IC, respectively.

The oscillating means 20 is connected to the power supply means 10 and receives a constant voltage to output a predetermined square wave pulse. The oscillation means 20 includes resistors R2 and R3 connected to the input terminal of the NE555 timer integrated circuit 20IC, And a capacitor C4. Here, by changing the capacitances of the resistors R2 and R3 and the capacitor C4, it is possible to output a pulse having a predetermined width and period.

The sequential control means 30 may comprise a decimal counter integrated circuit 30IC, a pulse width control unit 34 and a switching unit 36. [

The counter integrated circuit 30IC is connected to the output terminal of the oscillating means 20 and is connected to the input terminal of the oscillating means 20 through a plurality of output terminals Q8, And outputs a pulse signal. That is, when a pulse is inputted to the integrated circuit 30IC, the square-wave pulse signal is sequentially output through the plurality of output terminals Q0 to Q8, and after one rotation, the pulse is returned to the reference output terminal, Thereby outputting a rhombohedral pulse signal. At this time, if a low signal is inputted to the clear terminal 15, the integrated circuit 30IC outputs one square wave pulse signal sequentially from the output terminal Q1 to Q8, and then outputs a rectangular wave pulse signal to the reference output state . In this way, the counter integrated circuit 30IC sequentially outputs a square wave pulse through the output terminal every time a low signal is input to the clear terminal 15, and returns to a reference state in which a rectangular wave pulse is output to this output terminal.

The pulse width control unit 34 includes resistors R6 to R13 and capacitors C5 to C12 connected in series to the respective output terminals Q8 to Q8 of the counter integrated circuit 30IC, Q13 and Q8 and the resistors R6 to R13 and the terminals of the capacitors C5 to C12 not connected to the resistors R6 to R13 are connected to the grounded resistors R6 ' And diodes (D2 to D9) to which one side is connected and the other side is grounded.

With such a configuration, when a rectangular wave pulse is inputted from the output terminal Q1 by the sequential control of the integrated circuit 30IC, a high signal is outputted through the capacitor C5 only while the capacitor C5 is charged, The charge charged in the capacitor C5 is discharged through the diode D2 while the low signal is outputted after the pulse signal is outputted.

When the square wave pulse signal is input through the next output terminal Q2 in accordance with the order, the capacitor C6 and the diode D3 connected to the output terminal Q2 perform the same function as the output terminal Q1, A function of outputting a high signal only while being charged by the capacitors C7 to C12 and diodes D4 to D9 connected to the respective output terminals Q3 to Q8 in accordance with the order and discharging when the rectangular pulse signal becomes a low value Is performed. At this time, a high signal is applied to the output terminal of the pulse width controller 34 by the square wave pulse signal input to the input terminal of the pulse width controller 34.

Since the time is determined by the time constant by the resistors R6 to R13 (R6 'to R13') and the capacitors C5 to C12, by varying the resistance value and the capacitance of the capacitor, Can be adjusted.

The switching unit 36 is connected to the output terminals of the capacitors C5 to C12 of the pulse width control unit 34. The transistors TR1 to TR8 and the transistors TR1 to TR8, And the relays RE1 to RE8 are connected to the respective switch means S1 to S8. The connection relations of the transistors TR1 to TR8 and the relays RE1 to RE8 and the switch means S1 to S8 are the same and the operation thereof will be described as follows.

The pulse width control unit 34 drives the relay RE1 connected to the transistor TR1 only when the high signal is applied through the capacitor C5 while the transistor TR1 is turned on, do.

The TV setting detecting means 40 includes a switch SW0 provided on a transfer line of the TV set and being turned on and off by a limit switch 42 detecting that the TV set has been transferred to a set position, ), Capacitors C13 and C14, transistors TR9 to TR12, and a diode D10, and the operation thereof will be described with reference to the drawings.

The switch SWO is turned on when the TV set is conveyed to the set position and is detected by the limit switch 42. While the capacitor C13 is fully charged by the time constant of the resistors R14 and R15 and the capacitor C13, Flows through the capacitor C13 and is applied to the base terminal of the transistor TR9. Since the charge that has been charged in the capacitor C14 by the leakage current between the emitter terminal and the base terminal of the transistor TR11 flows through the transistor TR9, a low signal is applied to the base terminal of the transistor TR11, Therefore, the transistor TR11 is turned on. At this time, since the transistor TR10 is in a conducting state by the pulse signal applied from the reference output terminal Q1 of the counter integrated circuit 30IC to the base terminal, the transistor TR11, the resistor R18 and the transistor TR10 So that current flows.

Therefore, current also flows through the resistor R19, the resistor R20, the resistor R18 and the transistor TR10, so that the current at the base terminal of the transistor TR12 becomes lower than the emitter terminal, The current flows to the resistor R21 by conduction of the transistor TR12 and a high signal is applied to the clear terminal 15 of the counter integrated circuit 30IC connected to the collector terminal of the transistor TR12 .

When the total transition of the capacitor C13 is completed, the transistor TR9 is turned off, and the transistor TR11 and the transistor TR12 are then turned off. When the transistor TR12 is thus cut off, a low signal is applied to the clear terminal 15 of the counter integrated circuit 30IC connected to the collector terminal of the transistor TR12 and the counter integrated circuit 30IC is reset reset state and output square-wave pulses sequentially through the output terminals Q1 to Q8

That is, when the limit switch SW0 is turned on, the transistor TR12 is turned off for a predetermined time and then turned off to sequentially apply a high signal and a low signal to the clear terminal 15 of the counter integrated circuit 30IC, Thereby resetting the circuit 30IC.

The time edge portion 45 is composed of a transistor TR13 (TR14), a resistor R22 (R23), a capacitor C15 and a diode D11. While the transistor TR12 is turned on, the transistor TR13 conducts And the transistor TR14 is turned on while the capacitor C15 is charged by the current flowing through the transistor TR13 so that the relay mω is turned on and the switching means S9 turns on.

At this time, since the switch means S9 is connected to the switch means S10, a predetermined control connected to the switch means S9 is performed only when the switch means S10 is in the silver state. That is, the switch means S10 is a manual switch, and if the operator selects the OFF state, the switch means S9 does not perform any function even if the switch means S9 is in the silver state.

By providing the switching means S11 for extending the time for driving the relay RE9 with the resistor R23 as a variable resistor and for connecting both ends of the capacitor C15 to the transistor TR13, The relay RE9 may be configured to remain in the silver state continuously for a predetermined time. In this manner, the silver state of the relay (distance 9) is maintained for a predetermined time, and is used by being connected to a switch for maintaining the state for a predetermined time such as a volume during the screen setting of the TV set.

The memory means 50 stores predetermined signal data and is connected to the switch means S1 to S9. The memory means (50) outputs predetermined signal data corresponding to the switched switch means among the switch means (S1 to S9). The input means (52) connected to the memory means (50) is means for changing and storing the signal data stored in the memory means (50).

The TV control signal generating means 60 is connected to the memory means 50 and outputs a predetermined signal wave according to the signal data inputted from the memory means 50 to set the screen of the TV set 70 to a predetermined state .

When the power supply means 10 is in a normal state, the auxiliary power supply means 5 is charged. When the power supply means 10 is in a normal state, the auxiliary power supply means 5 is charged. It is preferable to supply power from the auxiliary power supply means 5 to the memory means 50 in order to prevent the data inputted to the memory means 50 from disappearing.

That is, when the power supply means 10 is in a normal state, the status indicating lamp LED is turned on and charged into the storage battery Vc via the three-terminal constant voltage integrated circuit 5IC, the diode DI and the switch SW1 Although not shown, during a power failure, the lamp (LED) is turned off and the voltage of the battery (Vc) supplies power to the memory means (50) through the switch (SW1).

An example in which the adjustment worker performs the volume inspection on the channel 03 will be described as an example.

First, the operator inputs the signal data to the memory means 50 using the input means 52. At this time, power switch-on signal data is supplied to the terminal of the switch means S1, channel 0 selection signal data is supplied to the terminal of the switch means S2, channel 3 selection signal data is supplied to the switch means S3, And volume select signal data, respectively. Then, when power is supplied to the system of the present invention, the counter integrated circuit 30IC outputs the square-wave pulse signal one time through the output stage (Q8) sequentially by the pulse signal supplied from the oscillation means 20, And outputs a square-wave pulse signal through the output terminal (i).

At this time, if it is detected that the TV set has been transferred to the set position in the limit switch 42, the TV setting detecting means 40 sets the counter integrated circuit 30IC to the square-wave direct circuit 30IC through the output terminals Q1 to Q8, And outputs a pulse signal. When the switch means S1 is turned on by the square wave pulse signal applied to the first output terminal Q1, the power switch-on signal data among the data stored in the memory means 50 is outputted, and the TV control signal In the means 60, the power switch sends a signal wave to the TV set 70 to turn on the TV set 70.

Then, the TV set 70 is selected as the channel 03 through the same process by the square wave signals outputted from the output terminals Q2 and Q3, and the switch means 35 is switched by the subsequent output terminals Q4 to Q8, (S4 to S8), there is no stored signal data. When the square wave pulse signal is again output from the reference output terminal, the switch means S9 is turned on by this signal, and the TV set 70 is selected as the volume in the same manner as the operation of the power switch. At this time, the switch means S11 for changing the variable resistance of the time paper edge portion 45 or connecting the both ends of the capacitor C15 is set to the negative state and the volume increase or decrease from the TV control signal generating means 60 So that the decrease signal is continuously transmitted for a predetermined time.

Thus, the TV set testing apparatus of the present invention can be used to select a TV set channel, contrast up / down, blit up / down, tint up / down, volume up / down, TV / The / ENTER function, RECALL function, and power on / off functions can be set automatically.

An embodiment of a sequentially and automatically controlled TV set test method having the above configuration will now be described with reference to FIG.

In the power supply step, a square-wave pulse signal is output through a reference output terminal (Q &thetas;) of the counter integrated circuit (30IC) by supplying power to the sequentially and automatically controlled TV set testing apparatus of the present invention and driving the oscillating means . At this time, when it is detected by the limit switch 42 that the TV set has been transferred to the set position (TV set detection step), a reset signal is inputted from the TV setting detection means 40 to the counter integrated circuit 30IC, The integrated circuit 30IC is brought into the reset state (reset step).

The sequential control step is executed after the reset step. The rectangular wave output signals are sequentially outputted through the output terminals (Q1 to Q8) of the counter integrated circuit (30IC), and the TV set 70 is set to a predetermined state. When this sequential control step ends, the process goes back to the TV set detection step to re-execute the TV set detection step (sequential control end step).
