As a result, the retainer 43 comes into contact with the holding portion 39b and is held in that position.

Next, the operation of the above embodiment will be explained.

The operating portion 39c of the operating lever 39 is connected to the wire 35.
When the retainer 43 is pulled, the retainer 43 is pulled by the holding portion 39b. Then, in FIG. 6, the wire 35 acts to pull the retainer 38, which causes the lever 33 to rotate clockwise about the pin 34, and the vertical part of the lever 33 pulls the pin 32 into the piston rod 29. It acts like a push.

The pushed pin 32 is the gas spring 17
By pressing the inner valve, the gas spring 17 is unlocked and the piston rod 29 is extended by gas pressure. When the piston rod 29 extends, the arm 6 connected to it rotates clockwise around the pin 16, and along with this, the arm 7 also rotates in parallel around the pin 15, so it always maintains a constant angle. The auxiliary table top plate 5 rises while maintaining the .

When the valve of the gas spring 17 is unlocked and a downward force is applied against the pressure of the gas spring 17, the arm 6 rotates counterclockwise and the auxiliary table top 5 descends.

At this time, the arm 7 also rotates in the same direction around the pin 15, and the auxiliary table top 5 descends while always maintaining a constant angle.

After adjusting the height to an appropriate height in this way, when the operating lever 39 is released, the valve in the gas spring 17 returns to lock, thereby pushing the pin 32 back and fixing the auxiliary table top 5 in that position. Ru.

Next, the auxiliary table top 5 has a movable rail 4 that can slide inside the fixed rail 3, so
It can be moved back and forth. In other words, lower the height than the table top 2 and move it backwards,
When the fixed rail 3 is rotated about its axis 12, it can be stored on the underside of the table top plate 2 as shown in FIG.

It is also possible to directly attach the fixed rail 3 to the table top 2 so that it does not rotate, and to store the auxiliary table top 5 under the table top 2 by simply moving it backwards.

In addition, the auxiliary table top plate 5 has an angle adjustment screw 2
Turning 6 clockwise will tilt the front lower, and turning counterclockwise will tilt the front higher.

Since the present invention is configured as explained above, the top and bottom of the auxiliary table can be adjusted up and down, back and forth, and even the angle can be easily adjusted by hand, so that the keyboard can be adjusted to suit the body position of the operator. In addition to being able to match the
When the equipment on the table is not in use, you can leave the keyboard, etc. on the auxiliary table top and store it on the side under the table top, which eliminates fatigue caused by uncomfortable posture during operation. In addition to being useful, it also has the advantage of saving space.
