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.
