Patent ID: 7708238

Claim:
A visual presenter consisting of: a stage on which material is placed; a base which is discrete from the stage and is provided with a pivot shaft unit including a shaft support bracket; a support column mounted on the pivot shaft unit so as to be pivotable between a standing position and a forwardly-inclined position; a pivot shaft supported on the shaft support bracket; a single braking means consisting of a wave washer inserted through the pivot shaft to be tightened against the shaft support bracket by a nut in threading engagement with the pivot shaft, whereby a braking force is applied to the pivot shaft by tightening said nut; and a single return spring attached to pivot shaft and provided between said shaft support bracket and support column so as to apply a biasing force to the pivot shaft, the biasing force having a direction in which the support column is returned from the forwardly-inclined position to the standing position, wherein the braking force and the biasing force counteract a pivotal movement of the support column, and the base includes a counterweight disposed in the base so that the base is prevented from being moved during an operation of pivoting the support column.
