摘要： PROBLEM TO BE SOLVED: To perform focused exposure processing in which the moving speed precision of a surface plate is improved at low cost by removing a sucking function for holding the printing plate at the surface plate and a printing plate is surely brought into close contact with the surface plate, that is, the image forming point of exposing light is kept on the surface of a printing plate. SOLUTION: Just before a scanning position, a photopolymer plate 102 is pressurized toward the board 110 by gravity, etc., of a roller 270. With the plate 102 in close contact with the board 110 by this pressurizing, the surface of the plate 102 is scanned. By eliminating lifting of the plate 102 by the roller 270, the plate 102 can be held at the image-forming position of light beams to be in focus constantly.

摘要： PROBLEM TO BE SOLVED: To avoid waste of scanning time by storing a substantial image by a line sensor even when a line sensor is displaced by a piezoelectric element in the case where the piezoelectric element is employed to displace the line sensor. SOLUTION: Based on an output of a piezoelectric drive clock So2 from a counter 84, a piezoelectric signal P2 whose voltage is αV from a combination circuit 88 is amplified by an amplifier 96 and fed to a piezoelectric element 32. In this case, the piezoelectric element 32 is expanded, for example, based on the reception of the piezoelectric signal P2 to displace a vibration board 22 by a 2/3 pixel of a photoelectric conversion section of line sensors 28 (28a, 28b) in the main scanning direction Y. Thus, the line sensor 28 is set to a position displaced by 2/3 pixel. Then picture element signals b1, b2 photoelectric- converted by the photoelectric conversion section comprising the line sensor 28 are amplified (4) and stored in a storage area of a line buffer 76. Thus, waste of scanning time is avoided.

摘要： PURPOSE:To smoothly carry an original cassette while supporting the cassette with high precision by engaging a roller guide to a v-shaped groove of the original cassette and pressing a step at both sides of the guide onto contact with both side faces of the original cassette. CONSTITUTION:Both side face of an original cassette 14 are supported by plural guide rollers 74 in the cassette guide mechanism. In this case a guide 73 is engaged with a v-shaped groove 28a of the original cassette 14 and an outer circumferential face of steps 71a, 71b is abutted on vertical planes 19a, 19b of the groove 28a. Thus, the position in the horizontal direction and in the vertical direction orthogonal to the carrying direction is regulated for the original cassette 14. When the original cassette 14 is carried, since only the steps 71a, 71b are loaded, the original cassette 14 is smoothly carried.

摘要： PROBLEM TO BE SOLVED: To improve the easiness for carrying out a printing plate by relieving adhesion force for positioning and attraction due to static electricity when the printing plate is carried out from a surface plate.
SOLUTION: When a photopolymer plate 102 brought into contact with a surface plate 110 is carried out to a subsequent step, rollers 260 are protruded from the surface plate 110 so as to relieve adhesion force (insufficient relief of negative pressure by a vacuum pump 256, attraction due to static electricity or the like) generated between the surface plate 110 and the photopolymer plate 102, and the photopolymer plate 102 is supported on the rollers 260. Thereby, since the photopolymer plate 102 is floated with respect to the surface plate 110, a conveyance resistance due to the above adhesion force and attraction can be reduced.

摘要： PROBLEM TO BE SOLVED: To make reliably removable dust on the surface of a printing plate by blowing air to the printing plate and to suppress uneven exposure when the printing plate is exposed.
SOLUTION: When a photopolymer plate 102 is positioned on a surface plate 110 and conveyed to an exposure section 112 while retaining the flatness, dust 254 freezing to the surface of the photopolymer plate 102 by adhesive power or static electricity is made similar in condition to dust 254 which is simply on the surface of the photopolymer plate 102 by lightly rubbing the surface of the photopolymer plate 102 with the bristles 258 of a brush 256 before air for blowing dust 254 off is blown, accordingly the effect of air to blow dust off can be enhanced.

摘要： PROBLEM TO BE SOLVED: To remove dusts on a printing plate mounted on a surface plate and to lessen defects on picture quality. SOLUTION: This dust removing device 300 is disposed on the boundary between the first position when the surface plate 110 receives a photopolymer plate 102 from a photopolymer plate carrying part and the second position where the surface plate 110 is stored in an exposure part. The dust removing device 300 is provided with a blower 302 and a nozzle 304. The blower 302 is disposed linearly along the direction which intersects the moving path of the photopolymer plate 102, sends air toward the upper surface of the moving photopolymer plate 102 and blows off the dusts such as edge trash, paper powder of composite paper and rubber refuse on the photopolymer plate 102.

摘要： PROBLEM TO BE SOLVED: To prevent wear and damage of a surface plate and also damage of a rear surface of a printing plate. SOLUTION: On a top of a discharge structure part 164, a receiving guide 167 is mounted through a bracket 167A. When a photopolymer plate 102 is discharged from a photopolymer plate conveyance part 130, a tip part 102A of the photopolymer plate, somewhat hanging, comes into contact with a flat plate part 167B of the receiving guide 167. After that, the receiving guide 167 moves corresponding to movement of the tip part 102A of the photopolymer plate 102. Just before conveyance of the photopolymer plate is completed, the receiving guide 167 escapes ahead in the photopolymer 102 conveyance direction, which makes the photopolymer 101 land on the surface plate 101.
