Further, the upper stage moving unit 40 is arranged on the lower stage base unit 30 via a slide means 33 that is provided on the opposite side of the lower stage base unit 30 and slides in the width direction of the printing paper 100 with respect to the lower stage base unit 30. It is mounted so as to be movable.

  The slide means 33 includes an adjustment piece 331 that is fixed to the back surface 30 a of the lower base portion 30. The adjustment piece 331 has a U-shaped upper surface of the bent piece fixed to the back surface 30a, and a nut on one side so that the guide shaft 332 can rotate so as to penetrate the U-shaped paired piece. A dial-shaped grip portion 334 is attached to the other side of the guide shaft 332 that is fixed at 333 and is located on the side surface of the lower base portion 30.

  A screw shaft is formed on the guide shaft 332 that rotates together with the grip portion 334, and a hole portion 337 provided in a standing piece 336a on one end side of a moving plate 335 formed of a folded piece having a U-shaped cross section is screwed. Has been. Further, a cylindrical moving pin 338 is fixed to the moving plate 335 and is disposed so as to protrude from the upper surface of the lower stage base portion 30. A spring 339 that constantly urges the movable plate 335 toward the support portion is attached to the standing piece 336b on the other end side of the movable plate 335 between the support portion 35 provided on the back surface of the lower base portion 30.

  An extension piece 331a is connected to the spring 339 arrangement side of the adjustment piece 331, and the lower surface thereof is in a position where it abuts against the movement plate 335, so that the movement plate 335 slides along the extension piece 331a. . The extension piece 331a of the adjustment piece 331 is formed with a long hole 331b for the movement pin 338 to move so that the movement plate 335 can slide.

The upper stage moving unit 40 is provided with a hole 42 through which the moving pin 338 passes. The hole 42 is formed with a diameter that is slightly larger than the diameter of the moving pin 338 in the vertical direction of FIG. The main purpose of this is to enable the moving pin 338 to be inserted into the hole 42 of the upper moving part 40 even if there is a manufacturing error or assembly error in each of the hole 42 and the moving pin 338.
Further, the movement pin abutting portions 43a and 43b are provided on the upper surface side of the upper stage moving unit 40 at positions where the moving pin 338 is sandwiched in the left-right direction, thereby converting the linear motion of the moving pin 338 into the rotational motion of the upper stage moving unit 40. The upper moving unit 40 can rotate about the fulcrum pin 31 and the fulcrum boss 41 on the lower base unit 30 in accordance with the sliding movement of the moving pin 338 (the upper moving unit 40 moves in the vertical direction with respect to the moving pin 338. To move slightly).

When tilted, the arrow portion 46 of the indicator portion 45 indicates the scales of the scale portions 36 and 36 provided corresponding to the lower base portion 30 according to the ratio. The scale portion 36 is configured to indicate how much the center portion is shifted to the left and right. In addition, although the indicator part 45 and the scale part 36 were provided in a pair on the left and right, only one of them may be installed because it displays the same information.

According to the configuration of the slide means 33 described above, when the grip portion 334 is rotated, the guide shaft 332 rotates and the moving plate 335 slides along the extension piece 331 a of the adjustment piece 331 while receiving the pulling force by the spring 339. Due to the presence of the spring 339, it is possible to eliminate “play” with respect to the rotation of the grip portion 334, and to smoothly move the moving plate 335 with respect to the rotation of the guide shaft 332.
As the moving plate 335 moves, the moving pin 338 moves, and the upper stage moving part 40 moves in the width direction of the print sheet, so that the upper stage moving part 40 is centered on the fulcrum pin 31 and the fulcrum boss 41 with respect to the lower stage base part 30. Rotate to tilt. The ratio of the inclination can be visually observed when the arrow portion 46 of the indicator portion 45 indicates the scale portion 36. When the lower base part 30 and the upper stage moving part 40 completely overlap, the scale part 36 shows the scale at the center position in the scale part 36 by the arrow view part 46 of the indicator part 45, and the lower part is rotated by the rotation of the grip part 334. When the upper stage movement part 40 inclines with respect to the base part 30, it is comprised so that the arrow view part 46 may show the scale which shifted | deviated to the right and left with respect to the center position.

The side plates 21a and 21b installed on the upper stage moving unit 40 are fixed on a guide member 23 that moves in a guide rail 22 that is long in the width direction. Rack gears 24 parallel to the guide rails 22 are mounted on the lower surfaces of the side plates 21a and 21b, and each rack gear 24 is configured to mesh with a disk gear 25 mounted at the center on the upper stage moving unit 40. . Therefore, when one of the side plates 21a and 21b is slid along the guide rail 22, the other side plate is also moved by the same distance, so that the side plate 21a matches the width of the printing sheet disposed between the side plates 21a and 21b. , 21b can be adjusted.
In addition, a side plate fixing member 26 that is in contact with the vertical plate of the side plate 21 and restricts movement is fixed to the outer position of the side plate 21 a with a fixing screw 27. When it is desired to fix the distance between the side plates 21a and 21b, the side plate fixing member 26 may be attached.

A case where the printing sheet is cut using the cutting apparatus having the above structure will be described.
The print sheet 100 is placed on the paper table 20 mounted on the paper supply unit 2, and the distance between the side plates 21 a and 21 b is adjusted so as to match the width of the print sheet 100.
At this time, as shown in FIG. 4 and FIG. 9B, when the printing unit (image region) 100 a is inclined and printed with respect to the four corners of the printing sheet 100, the lower base unit 30 is correspondingly printed. The upper moving unit 40 is tilted.

  That is, the guide shaft 332 is rotated by rotating the grip portion 334, and the moving plate 335 is slid in accordance with the rotation direction with respect to the width direction of the lower base portion 30 (width direction of the print sheet). When the moving plate 335 slides, the moving pin 338 fixed to the moving plate 335 also moves simultaneously, and the upper stage moving unit 40 fitted with the moving pin 338 moves in the width direction of the printing sheet, so that the lower stage base unit is moved. 30, the upper stage moving part 40 rotates and tilts around the fulcrum pin 31 and the fulcrum boss 41. The ratio of the inclination can be visually observed by the arrow portion 46 of the indicator portion 45 indicating the scale portion 36. For example, if the inclination of the image region 101a in FIG. 9B is (XY) mm. For example, the value obtained by dividing the length (constant value) of the upper moving unit 40 by the length (random value) of the image region 101a is multiplied by the (XY) until the arrow unit 46 is aligned with the scale of the value. The grip part 334 is rotated.

  As a result, the printing sheet 100 is arranged so that the cutting surface of the printing portion (image region) 100a of the printing sheet 100 is along the conveying direction, so that the cutting by the straight blade units 66 and 67 and the slitter units 71 and 72 are performed. Cutting can be performed on a cut surface along the outer periphery of the image area 100a, and even when the printing unit (image area) 100a is inclined with respect to the printing paper 100, the printing unit (image area) is separated from the printing paper 100. ) 100a can be cut at the outer periphery of the image.
