た。<Prior Art and Problems> The above conventional device connects the base frame provided on the bottom surface of the main top plate and the support arm provided on the bottom surface of the auxiliary top plate with two parallel links, upper and lower. By connecting rotatably to form a parallel four-bar link, and by installing a gas compression device between the diagonal parts of this parallel four-bar link mechanism, the swing of the parallel four-bar link mechanism can be controlled at a desired position. It was designed so that it could be stopped, and the base frame was movable back and forth on the underside of the main top plate. (Utility Model Application No. 60-77426) [Problem to be solved by the invention] However, by positioning the base frame at the front end of the top plate and swinging the parallel four-rod link mechanism, it is possible to move the auxiliary top plate to the main top plate. If the keyboard is moved forward and placed on the auxiliary top plate, a part of the user's body collides with the auxiliary top plate, or if the user leans against the auxiliary top plate. If the auxiliary top board suddenly moves behind the main top board and collides with the front edge of the main top board, or the keyboard collides with the main top board and falls from the auxiliary top board, There was some damage.

つた。 On the other hand, when the base frame was located behind the top plate and the keyboard was placed on the auxiliary top plate stored below the main top plate, the parallel four-rod link mechanism was accidentally moved by lever operation. When it was rocked, the keyboard that had risen up to the bottom of the main top plate collided with it, causing damage.

るものである。 With this invention, even if you accidentally operate the lever, if the keyboard is in a position where it collides with the bottom surface of the top plate,
If the parallel four-bar linkage mechanism does not swing, and if the keyboard is in a position where it collides with the top plate and falls due to movement of the base frame, the base frame will not move backwards and the auxiliary top plate will We provide a mounting device for keyboards, etc. that allows the parallel rod link mechanism to swing and the base frame to move only when the upper keyboard is in a position where it will not fall or collide with the bottom surface of the top plate. It is something to do.

is located at approximately the same height as the top plate 10 shown by the solid line in FIG. 1, and this state is maintained.

置板１は任意の高さで固定される。 Note that if the operation of the operating rod 81 is stopped midway, the air cylinder 8 is free-locked, so the mounting plate 1 is fixed at an arbitrary height.

作する事が出来る。 Moreover, when the mounting plate 1 is in the state shown in FIG. 1, the slide stopper 37 provided at the rear end of the first interlocking rod 3 is
Since the stopper protrusion 75 of the holding seat 7 is located protruding from the front end, the keyboard can be safely operated on the mounting plate 1 without the mounting plate 1 moving backwards carelessly.

移動が可能となる。 Then, by operating the operating rod 81 and applying force from above, the top of the slide stopper 37 is located below the stopper protrusion 75 in the state shown in the imaginary line in FIG. The plate 1 can be moved backward.

できる。 At this time, there is a certain distance between the top plate 10 and the placement plate 1, so even if the keyboard is placed on the placement plate 1,
Even if the keyboard is placed on the top, it does not come into contact with the top plate 10, and the keyboard can be stored on the underside of the top plate 10.

Therefore, the mounting plate 1 does not move upward.

Rail contact portions 71 provided at the front and rear ends of
and is regulated by the rail rear end stopper 76.

ボードが不測に天板下面に衝突する事がない。<<Effects>> As described above, the present invention has a slide stopper that protrudes upward on the upper surface of the rear end of the first interlocking rod, and a slide stopper that protrudes forward on the lower surface of the top plate in correspondence with the slide stopper. Only when located
Since a stopper protrusion is formed that allows the first and second interlocking rods to swing, even if the air cylinder operating rod is operated by mistake while the keyboard is stored on the underside of the top plate, the slide stopper will not move. Since the pad comes into contact with the lower surface of the stopper protrusion and prevents the first and second interlocking rods from swinging, the placing plate will not rise and the keyboard will not accidentally collide with the lower surface of the top plate.
又、スライドストツパーがストツパー突条の前
方に位置した時、第１連動杆は上方に揺動する。 Further, when the slide stopper is located in front of the stopper protrusion, the first interlocking rod swings upward.

る事が出来る。 Then, when the mounting plate reaches a predetermined height or higher (at least when the keyboard is placed and the top surface of the keyboard is located above the bottom surface of the top plate), the top end of the slide stopper is lower than the bottom surface of the stopper protrusion. Since it is located at the top, even if the mounting plate moves backward, the slide stopper will come into contact with the front end of the stopper protrusion, and the mounting plate will not move backwards carelessly. You can operate the ho board with confidence.
