An electromechanical switching system which includes a multi-stage gearbox which has a plurality of manually selectable gear ratios corresponding to a plurality of positions of components which are movable between these positions, apparatus for automatically locating the components in the position corresponding to the selected gear ratio, and a device for locking the gearbox in a selected gear ratio while the operation is running. The position of the components is monitored and an indication provided the operator to prevent the start before the components are correctly positioned.

Electromechanical switching system

Disclosed is a device for transporting an original to be copied while resting on a supporting surface, preferably a drum, in a reproduction apparatus, comprising: a shaft extending across the width of the supporting surface and being arranged in spaced relationship substantially parallel therewith; a plurality of means in spaced attachment along the shaft and responsive to rotation of the shaft for clamping the leading edge of the original; a flexible strip member commonly covering the clamping means and being adapted to protect the leading edge of the original in the clamped position; means engaging one end of the shaft in an original-receiving position for opening and closing the clamping means by rotating the shaft; and means engaging one end of the shaft in an original-releasing position for opening the clamping means by rotating the shaft.
