して構成する。 C is a lever made of an elongated plate, and a knob 10 facing the outer surface of the frame 6 is fixed to the front end of the lever C, which extends above the support rod 8 in the front-rear direction. The inner end of the lever C is pivoted above the end of the frame plate 9 so as to be able to rotate around a fulcrum 0, and a U-shaped connecting piece 3 is provided on the upper surface of a portion of the lever C that is slightly away from the fulcrum 0. A U-shaped connecting piece 4 is fixed to the lower surface of the portion of the deck A that becomes the lateral upper part of the connecting piece 3 when the lever C rotates in one direction and the deck A becomes horizontal. Both ends of the elongated stay 5 are rotatably connected to the connecting pieces 3 and 4 via pins 11 and 12, respectively.
Elastic pieces 13 and 14 are interposed between the pins 1 and 14 to prevent rattling, respectively, and the pin 1 is installed upright near the connecting piece 3.
5 is connected to one end of a tension spring 16 that can cross above the fulcrum 0, and the other end of the tension spring 16 is connected to a support piece 17 fixed to the side surface of the frame 7 above the frame plate 9. and configure.

をすることができることになる。 Also, if you hold the knob 10 from the front and rotate the lever C as shown by arrow A, the elongated stay 5
will stand up and push up the deck A, and when the lever C rotates until it abuts one of the upright ends 8a as shown in FIG. 7 and the tension spring 16 passes over the fulcrum, the As shown in Figures 9 to 9, the elongated stay 5 is held upright, and the deck A is tilted as shown in Figures 8 and 11, and the books placed on the deck A are tilted. This means that you can read in a tilted position and write in a tilted position.

して好適に実施できる特長を有する。 In this way, the present invention pivots the lower surface of the front end side of the deck A to the underframe B above the supporting leg 1 via the hinges 2, 2, so that the lower surface of the front end side of the deck A is pivoted to the underframe B above the support leg 1, and the lower surface of the deck A is attached to the lower side of the rear end side of the deck A. The end of a lever C extending horizontally in the front-rear direction is pivotally attached to the part on the frame B side so as to be rotatable about a fulcrum 0, and a connecting piece 3 of the part of the lever C near the fulcrum 0 is attached. Both ends of the elongated stay 5, which can change from the sideways to the upright position, are connected freely to the connecting piece 4 on the lower surface of the deck A, which is the upper side thereof, so that the lever C cannot be rotated. Deck A can be quickly and easily leveled or tilted using only manual operation, and by tilting deck A, books can be placed in a position that is easy to view or write. It has the advantage of being able to be suitably implemented in a structured manner.
