Therefore, the stage equipment 2 cannot be raised above the appropriate height (A) or lowered below the appropriate height (B), and is raised between the appropriate height (A) and the appropriate height (B), and the stage It is possible to prevent the equipment 2 from being damaged due to excessive elevation.

Since the basic operation of the stage equipment elevating system is the same as in the prior art, a detailed description thereof will be omitted.

Hereinafter, the present invention will be further described.

First, in the present invention, the control unit 40 controls the system by receiving signals from each component of the present invention or by using data previously stored therein including the memory unit 45.

It further includes an auxiliary upward titration switch 36 and an auxiliary downward titration switch 37 operated by the slide block 33 to output a signal.

The control unit 40 monitors the signals of the auxiliary descending titration switch 37 and the auxiliary ascending titration switch 36, and the auxiliary ascending titration switch 36, a position or the auxiliary descending titration switch 37, b position), when a signal (by FIG. 7B at points a and b) is output, the drive motor 12 of the winch 10 is operated down at a predetermined speed including 50% of the set normal drive motor speed. Make the stage equipment (2) rise or fall slowly.

At this time, the initial down speed includes deceleration to 50% of the original speed and starts to ascend or descend, and the ascending or descending speed from this point (a or b) gradually decelerates and accelerates lower than the decelerated speed, for example 50% -> 30% -> 10% -> 5%, so that the stage equipment can be stabilized by making it rise or fall with deceleration acceleration.

When a signal is output from the auxiliary upward titration switch 36, the distance between the auxiliary upward titration switch 36 and the upward titration switch 34 set in advance in the memory unit 45 (a -> A, g1) Or, if the operating time is detected at the time of rising,

When the motor operates for a predetermined distance or time, the operation of the motor can be stopped regardless of the output signals of the appropriate switches 34 and 35.

The method of reducing the speed of the motor in the above can be implemented in various ways, and as an example, when a switching means is provided between the motor and the power applied to , so that each of the auxiliary lowering / raising appropriate switches 36 and 37 are operated, The control unit primarily gives a step wave signal to the switching means so that only 1/2 of the switching means is turned on so that the power applied to the motor is also 1/2.

Thereafter, the timing at which the switching means is turned on is changed and controlled to correspond to a predetermined distance or time information, and the step wave high period at which the motor operates is changed and controlled. Accordingly, the driving period of the motor is changed, so that the motor decelerates and accelerates.

The above has been described as an example, and controlling the motor speed may be implemented in other ways that have already been implemented.

Information for controlling the switching unit corresponding to the predetermined distance or time information is stored in the memory unit 45, and the control unit 40 can control it using this information.

The distance or time information predetermined above is (a->A, g1), (b->B, g2) section distance and information on the rotation time of the lead screw when operating normally for the section distance, slide according to the rotation The block movement distance or the time information for which the low output signal of the transistor is continuously maintained in FIG. 7B during normal operation is stored in advance in the memory unit 45 through measurement, etc., and the control unit uses at least one of them when a situation occurs. / If the stored information is satisfied by comparison (distance and time values are detected as much as the stored information), the motor operation is controlled to stop regardless of the output signals of the appropriate switches 34 and 35.

The above operations are performed by counting information previously stored in the memory unit 45 or operation input information of each switch in the control unit.

On one side of the exterior of each switch (34, 35, 36, 37), a light emitting diode (LED) 70 is provided so that the corresponding switch is operated based on the slide block, and based on this, power is applied to the transistor base In this case, the LED is TURN ON, so that the LED outputs light so that the user can check whether each switch is operating.
