The lid opening and closing means 6 configured as described above should be driven together with the lifting and lowering of the monitor 100.

That is, as shown in FIG. 1, the lid 5 should be closed in a state where the monitor 10 is lowered and opened in a state where the monitor 100 is raised as shown in FIG. 2.

The operation of the lid opening and closing means 6 will be described in connection with the lifting and lowering of the monitor.

First, as shown in FIG. 1, when the monitor 100 is lowered and the power is applied to raise the monitor 100 while the lid 5 is closed, the lid motor constituting the lid opening and closing means 6 first. Power is supplied to the 60b so that the sliding rod 63 is lowered so that the lid 5 is moved vertically inside the front of the frame 1.

When the opening of the lid 5 is completed, power is supplied to the elevating motor 40 so that the tow line 4 is released from the take-up pulley 40a. Thus, by the pressure of the gas spring 3 by the unwinding of the tow line. The monitor support plate 2 is pushed up to raise the monitor 100.

At this time, the driving speed of the lifting motor 40 should be adjusted to loosen the traction cord 4 at a slower speed than the rising speed of the monitor support plate 2 pushed by the pressure of the gas spring (3).

Because the pressure of the gas spring 3 pushes the monitor support plate 2 upward even when the monitor is lowered, the traction cord 4 is wound around the winding pulley 40a so that the monitor support plate 2 does not rise. When the lifting motor 40 is rotated at a high speed in such a state that it is not in a state of being pushed upward in such a manner, the monitor support plate 2 suddenly rises due to the pressure of the gas spring 3, and the monitor 100 is shaken. Since it may be damaged by hitting other parts, the lifting motor 40 is gradually driven, so that the pressure of the gas spring 3 gradually acts to push up the monitor support plate 2.

The monitor support plate 2 is completely moved to the upper portion, and the monitor support plate 2 is in a state of blocking the pressure port 10b formed in the upper plate 10a, and the monitor 100 is exposed above the upper plate 10a. Becomes

At this time, the position sensor 71 operates to cut off the power supplied to the lifting motor 40 to stop the driving of the motor.

On the contrary, when the monitor 100 is lowered while the monitor 100 is exposed as shown in FIG. 2, when the power is supplied to the lifting motor 400 again, the lifting motor 40 rotates in the opposite direction to the pulley pulley. Tow line 4 is wound around 40a.

In this case, the lifting motor 40 is driven by a force greater than the pressure of the gas spring 3 so that the gas spring 3 contracts so that the monitor support plate 2 descends, and the position sensor 72 detects the monitor support plate 2. When the power supplied to the lifting motor 40 is cut off and the power is supplied to the lid motor 60b, the sliding rod 63 is raised to close the lid 5.

The state in which the lid 5 is fully open and completely closed is controlled by the driving time of the lid motor 60b previously input to the controller or by sensing the switching plates 76 in the position sensors 74 and 75. It can be controlled by interrupting the power supply of the lid motor (60b).
