DEVICE FOR TILTING DRAWING BOARD

PURPOSE:To enable the stationary tilt angle of a drawing board support frame to be regulated in a wide range so as to be set in a simple manner by telescoping the side stem sections of a guide bar so that the desired stopper section may be selected. CONSTITUTION:A guide bar 18 having telescopic side stem sections 18a and 18b is installed in such a way as to be freely rocked on either a base stand 14 side or a drawing board support frame 10 side, and plural numbers of stopper sections 16 which detachably lock the guide bar 15, are provided on the other side so as to be arranged in the straight line direction. when the drawing board support frame 10 is made to be set at a great tilt angle, the side stem sections 18a and 18b may be set longer. And when it is made to be set at a small tilt angle, the said stem sections 18a and 18b may be set shorter. The guide bar thereby may be locked at the desired stopper out of the plural numbers of the stoppers 16. This constitution enables the tilt angle of the drawing board support frame to be regulated in a wide range.
