Abstract
An apparatus capable of manually and electrically driving an optical unit comprising a manual operation unit for manually driving the optical unit, an electric drive unit for electrically driving the optical unit, a discrimination unit for discriminating whether the optical unit is electrically or manually driven on the basis of a drive command signal for driving the electric drive unit and a state changeover unit for switching the optical unit to an electrically driven state or a manually driven state on the basis of a discrimination result obtained with the discrimination unit.
Claims32
An apparatus capable of manually and electrically driving an optical unit comprising:
- a manual operation unit for manually driving said optical unit;
- an electric drive unit for electrically driving said optical unit;
- a first operation unit adapted to be connected to a casing which holds said optical unit, said first operation unit for remote operation of said optical unit by said electric drive unit having a first operation member for outputting a first command signal to said electric drive unit, said first command signal outputted from said first operation member being a first reference signal which is outputted when the first operation member is not being operated or a first drive signal which is outputted in correspondence to an operation amount when the first operation member is being operated;
- a second operation member provided on said casing for outputting a second command signal to said electric drive unit, said second command signal outputted from said second operation member being a second reference signal which is outputted when the second operation member is not being operated, or a second drive signal which is outputted when in correspondence to an operation amount when the second operation unit is being operated;
- a discrimination unit for discriminating whether said first operation member is being operated or not on the basis of said first command signal from said first operation member and for discriminating whether said second operation member is being operated or not on the basis of said second command signal from said second operation member;
- and
- a state changeover unit for switching said optical unit to an electrically driven state or a manually driven state on the basis of a discrimination result obtained with said discrimination unit.
