A sheet-fed offset rotary printing press with a convertible press mechanism includes a chucking cylinder, convertible cylinder, grippers, and air nozzles and blowing ports. The chucking cylinder conveys a sheet by holding its leading edge. The convertible cylinder is arranged downstream of the chucking cylinder in a sheet convey direction and holds a trailing edge of the sheet being conveyed by the chucking cylinder. The grippers cause the convertible cylinder to hold the sheet in a turned state when the sheet is to be transferred from the chucking cylinder to the convertible cylinder. The air nozzles and blowing ports are arranged at different heights on outer sides of two ends in a widthwise direction of the sheet, and blow air toward a center in the widthwise direction of the sheet which is turned over by the grippers, so as to separate the sheet from the chucking cylinder.

A moving member fixing apparatus includes a stationary gear, rotary gear, press member, and first and second flat inclined surfaces. The rotary gear is movably provided to the stationary gear. The press member presses the rotary gear to fix the rotary gear to the stationary gear, and cancels pressing the rotary gear so that the rotary gear is released from the stationary gear. The first flat inclined surface is formed to be associated with the stationary gear. The second flat inclined surface is formed on the press member and comes into contact with the first inclined surface
