An electric circuit is formed in the unit 35 as shown in FIG. 4, for example, and operates as shown in the flowchart of FIG. The flow chart of FIG. 5 shows only the case where the transmitter 44 is used for control operation.
As can be seen from the circuit diagram in the figure, the other switch operating parts 6
The same applies to the case where control operations are performed using a, 6b and the switch box 41, and the same applies when these different operating means are used simultaneously. A case where the operation of this circuit is operated by the transmitter 44 will be described. First, it is assumed that the door body 4 is closed. When the open button 36d of the transmitter 44 is pressed, a light emitting diode LED (not shown) of the transmitter 44 is turned on to emit a signal radio wave, and when the signal reaches the receiver 45, a light emitting diode LED (not shown) of the receiver 45 is displayed. ) Lights up, the automatic reset type switch OSWd is turned on via the receiver 45, the electromagnetic contactor MC ₁ of the address ₁ is excited, and the contact M on the forward side of the motor drive circuit is excited.
C ₁ is turned on, and the motor 34 of the drive unit 5 rotates forward to open the door body 4. At the same time, a self-holding circuit is formed in the electromagnetic contactor MC _1, and the opening operation is continued even if the switch OSWd is turned off. Thus, if no abnormal load is applied to the door body 4, the opening operation continues, and when the door body 4 reaches the fully open state, the upper limit switch LSO is turned off and the self-holding circuit of the electromagnetic contactor MC ₁ is released, and the motor is released. The contact MC _{1 of the} drive circuit is turned off, the motor 34 stops, and the door body 4 stands still. However, when an abnormal load is applied to the door body 4 during operation and the overload detection circuit 47 outputs, the electromagnetic contactor MC ₂ at address ₂ is excited and the contact MC ₃ of the motor drive circuit is turned off. Is stopped and the door body 4 is stopped halfway. In this state, the self-holding circuit of the electromagnetic contactor MC ₃ operates, so after removing the cause of overload, even if the open button 36d or close button 37d of the transmitter 44 is pressed, each open / close switch OSWd, CS
Wd does not work. In this case, it is necessary to release the self-holding circuit of the electromagnetic contactor MC ₃ by pressing the reset button 38 of the switch operating unit 6a provided on the column 1 to open the reset switch RSW. This is to ensure safety in the event of an abnormality. After resetting, when the open button 36d or the close button 37d of the transmitter 44 is pressed, a predetermined operation is performed. Also, when the close button 37d of the transmitter 44 is pressed during the opening operation, the automatic reset type switch CSWd is turned on via the receiver 45, the electromagnetic contactor MC ₂ of the address ₂ is excited, and the contact of the address 1 is contacted. the MC ₂ off the motor by releasing to temporarily contact MC ₁ in forward rotation of the motor driving circuit is turned off and also exciting the address 2 of the electromagnetic contactor MC ₂ a self-holding electromagnetic contactor MC ₁ of address 1 The motor MC 34 is rotated in reverse by turning on the contact MC ₂ on the reverse side of the drive circuit, and the door 4 is closed. At the same time, the electromagnetic contactor MC ₂ at address 2 forms a self-holding circuit. When the door body 4 reaches the fully closed state in this way, the lower limit switch LSC is turned off and the self-holding of the electromagnetic contactor MC ₂ at address 2 is released to release the contact MC _{2 of the} motor drive circuit. Is turned off, the motor 34 is stopped, and the door body 4 is stopped in the closed state. If the open button 36d is pressed during the opening operation, or if the close button 37d is pressed during the closing operation, each operation is continued.
Further, as shown in the lower half of the flowchart of FIG. 5, the operation when closing the door body 4 that was initially opened is the same as that described above. Next, the function of the mode changeover switch 42 provided on the outdoor switch box 41 will be described. In FIG. 4, OSWa is a switch that is turned on by operating the open button 36a of the switch operating unit 6a, OSWb is a switch that is turned on by operating the open button 36b of the switch operating unit 6b, and OSWc is an open button 36c of the switch box 41.

The switch CSWc that is turned on by the switch CSWd is a switch that is turned on by the close button 37c of the switch box 41, and is provided in parallel with the switch CSWd. The mode changeover switch 42 includes the switches OSWa and OSW described above.
It operates six switches SWm inserted in series with b, OSWc, CSWa, CSWb, and CSWc. When the mode changeover switch 42 is turned on, the switch SWm is turned on. Therefore, if the mode selector switch 42 is turned on, the switches OSWa, OSWb, OSWc, CSWa, CSWb, and CSWc are effective, and both switch operation parts 6a, 6b switch box 41 and transmitter 44 can be used to open the door. It becomes a multi-mode in which the body 4 can be opened and closed. On the other hand, when the mode changeover switch 42 is turned off, the switch SWm is turned off and each switch O
SWa, OSWb, OSWc, CSWa, CSWb, CSWc are equivalent to the OFF state, and the switch operating parts 6a, 6b and the switch box 41
Becomes inoperable, and the remote control dedicated mode by the transmitter 44 is set. Further, if the right two terminals 40 for the mode changeover switch 42 among the terminals 40 shown in FIG. 2 are short-circuited by the conductors, the switch SWm is fixed in the ON state and the mode changeover switch 42 is disabled. Therefore, it is possible to prevent the mode from being switched to the remote control-only mode due to mischief.
Conversely, when the mode switch 42 is turned on, the switch SW
With the configuration in which m is turned off, the terminal 40 can be dedicated to remote control regardless of the switching of the mode switching switch 42 due to the short circuit. The electric garage door configured as described above, for example, when the car is in and out, the transmitter 44 is loaded in the car,
The opening / closing operation of the door body 4 can be remotely controlled by sending a signal from the inside of the vehicle to the receiver 45 without getting off the vehicle. In addition, when the transmitter 44 is not loaded in the automobile, the door body 4 can be opened and closed by pushing the switch operating parts 6a and 6b provided on the pillar 1 on the indoor side with the hand out of the driver's seat. is there. Especially, since the switch operating parts 6a and 6b are provided on the columns 1 on both sides,
Regardless of whether it is a domestic car or a foreign car, or whether the front side of the car is facing the indoor side or the outdoor side, the opening / closing operation of the door body 4 can be performed from the inside of the vehicle regardless of which side the driver's seat is. Of. Further, when the transmitter 44 is not provided, the switch box 41 is used to open and close the door body 4 on the outdoor side. The position of the switch box 41 can also be set to a height that can be reached from the driver's seat. A person can pass through the door body 4 by opening and closing the door, and in this case, a person operates the switch operation parts 6a and 6b of the pillar 1 and the outdoor switch box 41 to open the door. The body 4 can be opened and closed to pass. The above electric circuit is an example, and the design can be changed as appropriate.
