複写機のコピースタート装置。In a copying machine in which an original on a contact glass is held down by a folding type pressure plate, the opening/closing center axis of the pressure plate is movable up and down, and when the folded back part of the pressure plate is closed against the contact glass, the center axis of the pressure plate is moved upward and downward. The first press actuated by a portion of the side.
a second switch that closes against the contact glass on the front side of the bend in the pressure plate and operates when there is an original on the contact glass; and both the first and second switches operate simultaneously. A copy start device for a copying machine, comprising: a circuit that generates a copy start signal when the copy start signal is activated.
