Abstract:
A visual presenter includes a base having 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 bracket, a wave washer inserted through the shaft to be tightened against the bracket by a nut in threading engagement with the shaft, and a return spring attached to the shaft so as to apply a biasing force to the shaft. 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.
