Then, the receiving unit 36 receives the electromagnetic wave signal. At this time, the electromagnetic wave signal s1 has three pulse signals shown in FIG. 3A or five pulse signals shown in FIG.
Alternatively, it is one of the single pulse signals shown in FIG. The receiving unit 36 transmits a pulse signal s1 similar to the electromagnetic wave signal to the control unit 37. Moving from step a2 to step a3, the controller 37 receives the pulse signal s1 and counts the number of pulses n of the pulse signal s1. The process proceeds from step a3 to step a4, where it is determined whether or not the pulse number n is 3.

The air in the piston chamber 9b is released to the atmosphere via the pipeline 24, the fourth port 23 and the second port 20. Thus, the piston rod 10 is displaced in the extension direction A2, and the door 8 is angularly displaced in the closing direction B2 about the axis of the hinge pin of the hinge 7 to close the door 8.

When the piston rod 10 extends to the forward limit, the operation proceeds from step a7 to step a9, in which the operation of the air compressor 17 is stopped, the driving state of the single-acting solenoid 26 is released, and the spool 29 is neutralized by the spring 27. Return to position. With the door 8 kept closed, the closing operation of the door 8 is completed.

If it is determined in step a6 that the pulse number n is not 5, that is, if it is determined that the pulse number n is 1, the process proceeds to step a8, and the opening or closing operation of the door 8 is stopped. To elaborate,
The control unit 37 outputs a signal s for stopping the operation of the air compressor 17.
2 when the door 8 is open, a signal s3 for canceling the driving state is transmitted to one of the single-acting solenoids 25, and when the door 8 is closed,
A signal s4 for canceling the driving state is transmitted to the other single-acting solenoid 26 to return the spool 29 to the neutral position 42. In step a9, the operation of opening or closing the door 8 is forcibly terminated while the door 8 is kept half open.

An electromagnetic wave signal shown in FIG. 3 is generated in response to the signal s5 transmitted from No. 9 and the electromagnetic wave signal is transmitted to the receiving unit.

FIG. 5 is a flowchart showing the operation procedure of the dedicated signal generating means 30. In step b1, the operation starts, and the process proceeds from step b1 to step b2 to determine whether any one of the buttons 32, 33, and 34 has been input. Here, each button 32,
Step b2 is repeated until one of 33 and 34 is input. If it is determined that any one of the buttons 32, 33, and 34 has been input, the process proceeds to step b3, where it is determined whether the open button 32 has been input. Here, when it is determined that the open button 32 has been input, the process proceeds to step b4, and the transmission unit 40 transmits the electromagnetic wave signals of the three pulses shown in FIG. More specifically, the processing unit 39 transmits a signal s5 for generating an electromagnetic wave signal of three pulses to the transmitting unit 40,
0 corresponds to the signal s5 from the processing unit 39 and corresponds to FIG.
And generates an electromagnetic wave signal of three pulses for opening the door 8 shown in FIG. The process moves from step b4 to step b8, and a series of operations ends.

If it is determined in step b3 that the open button 32 has not been input, the process proceeds to step b5, where it is determined whether the close button 33 has been input. Here, when it is determined that the close button 33 has been input, the process proceeds to step b6, and the transmitting unit 40 transmits the electromagnetic wave signals of five pulses shown in FIG. More specifically, the processing unit 39 transmits a signal s5 for generating an electromagnetic wave signal of five pulses to the transmission unit 40, and the transmission unit 40 corresponds to the signal s5 from the processing unit 39 and is illustrated in FIG. Then, an electromagnetic wave signal of five pulses for closing the door 8 is generated, and the signal is transmitted to the receiving unit 36. The process moves from step b6 to step b8, and a series of operations ends.

If it is determined in step b5 that the close button 33 has not been input, that is, if it has been determined that the stop button 34 has been input, the process proceeds to step b7, and the transmitting unit 40 performs the process shown in FIG. ) Is transmitted. More specifically, the processing unit 39 transmits a signal s5 for generating an electromagnetic wave signal of one pulse to the transmission unit 40, and the transmission unit 40 corresponds to the signal s5 from the processing unit 39 and is illustrated in FIG. An electromagnetic wave signal of one pulse for stopping the opening or closing operation of the door 8 is generated, and the signal is transmitted to the receiving unit 36. The process moves from step b7 to step b8, and a series of operations ends.

As described above, the electric power is supplied from the battery 31, the dedicated signal generating means 30 generates an electromagnetic wave signal indicating the opening or closing of the door 8, the reception control means 4 transmits the electromagnetic wave signal, and the door 8 is transmitted. Since the drive unit 2 that opens and closes is controlled, the opening and closing of the door 8 can be remotely controlled. Therefore, even when a large amount of large luggage is present near the door 8 or when a large number of people are present near the door 8 and cannot leave the door 8,
The opening and closing of the door 8 can be controlled. In particular, when the door 8 is closed, unless the remote controller 3 is operated, the door 8 is not opened, and the air conditioned for cooling and heating is not released into the atmosphere.

Since the pneumatic cylinder 9 is used for the driving means 2, the solenoid valve 18 is in the neutral position 42 even when the door 8 is open, closed, or half-open, whereby 1st to 4th port 1
9 to 23 are respectively closed, so that the pneumatic cylinder 9
The state of the door 8 can be maintained without the piston rod 10 being easily displaced in the retracting and extending directions A1 and A2 by the air supplied into the inside. In particular, when the door 8 is closed, the door 8 is not easily opened, which is effective for crime prevention.

[0024]

Receiving the infrared pulse and controlling the pneumatic cylinder 9 and the air compressor 17 for opening and closing the door 8, it is possible to remotely control the opening and closing of the door. Therefore, the door can be opened and closed even when a large amount of large luggage is present near the door, or when a large number of people are present near the door and cannot leave the door.

In particular, according to the present invention, the door 8 can be closed while the door 8 is being opened or closed. Therefore, it is possible to prevent the air conditioned for cooling and heating from being released into the atmosphere.

Furthermore, according to the invention, when the door 8 is closed, the solenoid-operated directional control valve 18 is in the second position 42 and therefore the two first and second piston chambers 9a, 9b of the pneumatic cylinder 9 are closed. Since the air is closed, the pneumatic cylinder 9 does not expand and contract, so that the door 8 does not open, which is effective for crime prevention.
