Claims (1)

[Scope of Claim for Utility Model Registration] {1} A board on which a keyboard of a word processor or the like can be mounted is provided with an operator's hand rest on which an operator's hands can be placed, and the operator's hand rest is protruded from the board. A mounting board for operating a keyboard in a word processor or the like, which is formed by a base part and a hand rest part whose height can be freely adjusted by operating an adjuster using a lift adjustment means. (2) The elevating means is located in the base section, stands upright on both left and right ends of the upper surface, and is rotatably supported vertically on a fixed shaft with a male screw installed on both left and right ends of the lower surface of the hand rest, A mounting board for keyboard operation in a word processor or the like as claimed in claim 1 of the utility model registration claim, in which a female threaded adjuster is screwed together. (3) The elevating means is located on the base, and engagement teeth are provided vertically on the lower part of the outer periphery of each adjuster that stands upright on both left and right ends of the upper surface, and between each of the adjusters, there are teeth on the inner periphery. The locking teeth are provided vertically, and a transmission belt that interlocks each adjuster and allows the hand rest to be raised and lowered in a horizontal state by rotating one adjuster is always in mesh with both of the teeth. A mounting board for keyboard operation in a word processor or the like as set forth in claim 1 of the utility model registration, which is rolled up. (4) In the elevating device, the cam that enables the hand rest to be raised and lowered is fixed to the cam shaft, which is rotatably supported on both sides of the base, by the outer periphery coming into contact with the inner surface iE of the hand rest. and an adjuster is fixed to one end of the camshaft on the outside of the side plate of the hand holder, and further controls the rotation of the adjuster.
Engagement small teeth located on the locking disc portion that protrudes inwardly and protruded from its outer periphery, and locking teeth that are located in a locking hole formed in the side plate of the hand rest portion and protrude from its inner periphery. The camshaft is configured to be slidable in the axial direction so that the camshaft is suppressed by meshing with the teeth, and the meshing of both teeth can be released by moving the camshaft in the axial direction. A mounting board for keyboard operation in a word processor, etc. as described in item 1. (5) The elevating device is rotatably supported on both side plates of the base part, and an adjuster placed outside the side plate of the manual rest part is attached to one end of the shuttle shaft which is equipped with a male screw. and a shuttle is screwed onto the shuttle shaft, and the shuttle and the hand rest move the hand rest up and down by the screw movement of the shuttle by the rotation operation of the adjuster, and the hand rest moves up and down. A mounting board for operating a keyboard in a word processor or the like according to claim 1, which is connected by a swingable link so as to be able to maintain a predetermined height. (6) The elevating device is rotatably supported on both side plates of the base part, and a worm shaft with a worm formed at both ends has a worm shaft with an adjuster disposed outside the side plate of the hand rest part at one end. A worm that is fixedly fixed and rotatably supported upright on both ends of the upper surface of the base, has a worm gear carved on its outer periphery to mesh with the worm, and has a female screw threaded on its inner periphery. The gear shaft has an elevating shaft which is vertically disposed from both ends of the lower surface of the hand rest part and has a male screw threaded thereon so that the hand rest part can be raised and lowered by the progress of engagement between the worm and the worm gear. A mounting board for keyboard operation in a word processor, etc., as set forth in claim 1 of the utility model registration claim, which is screwed together.
