Abstract: A printing press comprises a pair of left- and right-frames, a first printing plate guiding device provided at a location near a lower plate cylinder, swingably supported so as to be moved between a guiding position for guiding a new printing plate supplied to a lower plate cylinder or a discharged printing plate discharged from the lower plate cylinder and a shelter position released from the lower plate cylinder, a second printing plate guiding device provided at a location near the lower plate cylinder, swingably supported so as to be moved between a guiding position for guiding the new printing plate or the discharged printing plate and a shelter position released from the lower plate cylinder and a safety cover swingably supported so as to be moved between a closing position for closing at least one part of a space formed between the left- and right-frames and a releasing position for releasing the space. The first printing plate guiding device, the second printing plate guiding device and the safety cover are coaxially supported on a supporting axis. Thus, an operation space can be provided at a location near a plate cylinder even if a sufficient space is not provided above a printing unit.

Abstract: A sheet unloading apparatus is used for rotary drum rotatable in one direction along with a paper sheet which is wound around a peripheral surface of the rotary drum and at rear end mechanically engaged in an engagement groove formed in the peripheral surface. The sheet unloading apparatus includes a separation paws for separating a front end of the paper sheet from the rotary drum by contacting the peripheral surface of the rotary drum while the rotary drum rotates in the one direction, and a pair of pinch rollers for rotating to pinch and feed out the paper sheet supplied according to the rotation of the rotary drum in a state where the front end of the paper sheet is separated from the rotary drum by the separation pawl and the rear end of the paper sheet is engaged in the engagement groove. Particularly, the unloading apparatus further include a removal assisting mechanism for assisting the paper sheet to be pulled out from the engagement groove by bending the paper sheet spanning between the rotary drum and the pair of pinch rollers.
