ABSTRACT:
A printing switching apparatus for a sheet-fed rotary press with a reversing mechanism includes a fixed gear, a rotary gear, a first inclined surface, an engaging member, and an actuating unit. The fixed gear is fixed to a shaft of a cylinder. The rotary gear is coaxial with the fixed gear, coupled to be driven with a cylinder adjacent to the cylinder, and phase-adjustable with respect to the fixed gear in a circumferential direction. The first inclined surface is formed on the rotary gear. The engaging member is movable with respect to the fixed gear and has a second inclined surface pressed against the first inclined surface of the rotary gear. The actuating unit moves the engaging means in a direction to be separated from or come close to the fixed gear, presses or releases the first inclined surface of the rotary gear and the second inclined surface of the engaging member against or from each other, and connects or disconnects rotational transmission between the fixed gear and the rotary gear.
