A press plate mounting apparatus has a press plate placement portion capable of holding a press plate having a partially formed print face region, and a plate cylinder holding portion that rotatably holds a plate cylinder onto which the press plate is mounted. Positioning cross marks are provided in a non-print region of the press plate. The press plate placement portion includes a suction surface that sucks the print face region, and a scale member provided at a position outward of the suction surface and extending in a predetermined direction. The scale member is able to contact the locating cross marks when the press plate is held at a predetermined position. The scale member has a scale that makes it possible to visually check a positional deviation of the press plate in the predetermined direction.

1. Field of the Invention
The invention relates to a press plate mounting apparatus and, more particularly, to a press plate mounting apparatus capable of mounting a press plate easily and accurately onto an outer peripheral surface of a plate cylinder.
2. Description of the Related Art
FIG. 1 is a schematic perspective view of a press plate mounting apparatus in accordance with an embodiment of the invention in a state;
FIG. 2 is a schematic perspective view of the press plate mounting apparatus in another state;
FIG. 3 is a schematic plan view of the press plate mounting apparatus shown in FIG. 1;
Preferred embodiments of the invention will be described hereinafter with reference to the accompanying drawings.
FIG. 1 is a schematic perspective view of a press plate mounting apparatus 10 in accordance with the invention in a state. FIG. 2 is a schematic perspective view of the press plate mounting apparatus 10 in another state. FIG. 3 is a schematic plan view of the press plate mounting apparatus 10 shown in FIG. 1. FIG. 4 is a sectional view of the press plate mounting apparatus 10 taken on line A—A in FIG. 3, where a portion of the apparatus shown in FIG. 3 is omitted. The press plate mounting apparatus 10 shown in these drawings is an apparatus for mounting a press plate H onto an outer peripheral surface of a plate cylinder S that has been removed from a printing apparatus of a printing machine (not shown). The press plate mounting apparatus 10 has a press plate placement portion 14 for holding the press plate H, and a plate cylinder holding portion 17 for holding the plate cylinder S.
The plate cylinder S, in a form that is merely illustrative and not restrictive, has a generally cylindrical shape that has opening portions S1, S2 at two opposite ends thereof in the direction of an axis (left-right both end sides in FIG. 3) as shown in FIG. 3. The opening portion S2 on the right side in FIG. 3 has a generally “V”-shaped engaging groove S3 that has been cut out so as to extend toward the opening portion S1 on the left side in FIG. 3. An outer peripheral surface of the plate cylinder S is incised with a reference line S4 that extends in the direction of the axis (left-right direction in FIG. 3) from a position that is a predetermined distance apart from the engaging groove S3 in the circumferential direction.
