ABSTRACT:
A printing switching apparatus for a sheet-fed rotary press with a reversing mechanism includes a fixed gear, a rotary gear, a fixing unit, and a proximity switch. The fixed gear is fixed to the shaft of a first cylinder. The rotary gear is coaxial with the fixed gear, coupled to be driven with a second adjacent cylinder along a paper convey direction, and phase-adjustable with respect to the fixed gear in a circumferential direction. The fixing unit fixes the rotary gear to one of the fixed gear and the shaft of the first cylinder to perform rotational transmission such that phase switching of the rotary gear between single-sided printing and perfecting printing is performed when the fixing means is released, and the rotary gear is not fixed to one of the fixed gear and the shaft of the first cylinder. The proximity switch detects that the rotary gear is positioned in a phase of single-sided printing when the rotary gear is fixed to one of the fixed gear and the shaft of the first cylinder by the fixing means.
