In this embodiment, as shown in FIGS. 1 and 3, each standing frame wall 22 is arranged on the sheet feeding core 3 side, the first standing frame wall 221 having a relatively small height dimension, and the thermal head 4 side. And a second standing frame wall 222 having a relatively large height.

  The paper feed core 3 has a substantially disk shape that aligns the paper feed core shaft 31 and the side edges (edges in the width direction) of the wound printing plate attached in the vicinity of the axial end of the paper feed core shaft 31. A paper feed guide unit 32 is provided. The sheet feeding core shaft 31 pivotally supports an end portion in the axial direction (hereinafter, simply referred to as “end portion”) on the standing frame wall 22 (specifically, the first standing frame wall 221).

  The thermal head 4 heats a heating element (not shown) to record an image on a printing plate surface.

  The platen roller 5 can sandwich the printing plate with the thermal head 4 and can be rotated in the forward and reverse directions. The platen roller 5 is rotated while the printing plate is moved to the paper feed core 2 side or the paper discharge port 8 side. It has a function to convey appropriately. Therefore, the platen roller 5 has a part of the function of a transport mechanism that transports the printing plate together with the feed roller 6 and the pinch roller 7 described below.

The printing plate is discharged from the paper discharge port 8 in a cut state cut to a predetermined size.

  By the way, in such a configuration, when the relative relationship (see FIGS. 4 and 7) between the paper feeding core shaft 31 and the feed roller shaft 61 is not parallel, the printing plate is displaced in the width direction with respect to the transport direction. A so-called skew (skew) is conveyed. When printing processing (thermal transfer printing, sublimation printing) is performed on the printing plate on which such skew occurs, the printing content (output result) is inclined with respect to the printing plate by the amount of skew. Resulting in.

  Therefore, the thermal printing plate printer 1 according to the present embodiment is movable so that the reference portion set on the paper feed core shaft 31 can be moved to a position where the paper feed core shaft 31 and the feed roller shaft 61 are parallel to each other. An adjustment mechanism X is provided. In the present embodiment, the movable adjustment mechanism X is provided only at one end of the both ends of the paper feed core shaft 31. That is, in the thermal printing plate printer 1 according to the present embodiment, one end of the both ends of the paper feed core shaft 31 is set as a reference portion. In the following description, one end portion of the both ends of the paper feed core shaft 31 provided with the movable adjustment mechanism X is referred to as “one end portion of the paper feed core shaft 31”, and the movable adjustment mechanism X is not provided. The other end is referred to as “the other end of the paper feed core shaft 31”.

  As shown in FIGS. 4 to 7, the movable adjustment mechanism X is provided at one end portion of the paper feed core shaft 31 and supports the bearing portion 9 that supports the end portion, with the upright frame wall 22 (first upright frame wall 221). The position of one end of the paper feed core shaft 31 is adjusted to a position where the paper feed core shaft 31 and the feed roller shaft 61 are parallel to each other. Specifically, a core shaft insertion / removal opening 91 that is opened only in a direction (upward in the illustrated example) in which the paper feeding core shaft 31 is inserted / removed is formed in the bearing portion 9 having a substantially flat plate shape. With one end of the paper feed core shaft 31 inserted (attached) into the removal opening 91, the bearing portion 9 is in a predetermined direction with respect to the upright frame wall 22 (first upright frame wall 221) (in the illustrated example, thermal printing). The relative mounting position of one end portion of the paper feed core shaft 31 with respect to the standing frame wall 22 is positioned so that the paper feed core shaft 31 is parallel to the feed roller shaft 61 by moving in the longitudinal direction of the plate printer 1. Set to be able to.

  More specifically, the bearing portion 9 in which one end portion of the paper feeding core shaft 31 is inserted into the core shaft insertion / removal opening 91 is used as an inwardly facing surface (the other rising surface) of the standing frame wall 22 (first standing frame wall 221). One end portion of the paper feeding core shaft 31 when the bearing portion 9 is moved in a predetermined direction with respect to the standing frame wall 22 (the first standing frame wall 221) in a state of being applied to the surface facing the frame wall 22) The core frame moving opening 22a is formed in the standing frame wall 22 (first standing frame wall 221) so as not to interfere with the standing frame wall 22 (first standing frame wall 221).

  In the present embodiment, a long hole 92 extending in a predetermined direction (in the illustrated example, the front-rear direction of the thermal printing plate printer 1) is formed around the portion of the bearing portion 9 where the core shaft insertion opening 91 is formed. In the standing frame wall 22 (first standing frame wall 221), a protruding portion 22t protruding inward is provided at a portion that can come into contact with the bearing portion 9, and the protruding portion 22t is moved in the elongated hole 92 to thereby raise the standing frame. The relative position of the bearing portion 9 with respect to the standing frame wall 22 (first standing frame wall 221) can be smoothly changed while restricting the allowable movement range of the bearing portion 9 with respect to the wall 22 (first standing frame wall 221). Yes. That is, the protrusion 22t and the long hole 92 function as so-called dowels and dowel holes. In particular, in the present embodiment, a plurality of elongated holes 92 are formed in the bearing portion 9, and a plurality of protrusions 22 t are provided on the standing frame wall 22 (first standing frame wall 221), so that the standing frame wall 22 (first standing frame). The movement of the bearing portion 9 relative to the frame wall 221) can be performed more smoothly. In addition, screw holes 22n are provided in the standing frame wall 22 (first standing frame wall 221), while the bearing 9 is moved relative to the standing frame wall 22 (first standing frame wall 221) in the bearing portion 9. In this case, a communication hole 93 (round hole in the illustrated example) set to an opening size capable of always communicating with the screw hole 22n is formed. A screw (not shown) is screwed into the screw hole 22n through the communication hole 93. The other end of the paper feeding core shaft 31 is pivotally supported by a bearing hole 22b formed in the standing frame wall 22 (first standing frame wall 221).

  Next, a procedure for setting the paper feed core shaft 31 and the feed roller shaft 61 to a mutually parallel positional relationship using the movable adjusting mechanism X having such a configuration will be described.

  First, the screwed state of the screw hole 22n is loosened or released, and the bearing 9 that supports one end of the paper feed core shaft 31 is moved with respect to the standing frame wall 22 (first standing frame wall 221). Make it possible. And the bearing part 9 is moved along the surface of the standing frame wall 22 (1st standing frame wall 221) with respect to the standing frame wall 22 (1st standing frame wall 221). The relative movement of the bearing portion 9 with respect to the standing frame wall 22 (first standing frame wall 221) is caused by a long hole 92 formed in the bearing portion 9 with a protrusion 22t provided on the standing frame wall 22 (first standing frame wall 221). This can be performed while guiding, and the protrusion 22t abuts against the opening edge of the elongated hole 92, so that further movement in the same direction is restricted. After the bearing portion 9 is moved to the standing frame wall 22 (first standing frame wall 221) until the sheet feeding core shaft 31 and the feed roller shaft 61 are parallel, the screws are screwed into the screw holes 22n and tightened. To do. Through the above procedure, the paper feed core shaft 31 and the feed roller shaft 61 can be set in a mutually parallel positional relationship.

  The operation of adjusting the parallel relationship between the paper feed core shaft 31 and the feed roller shaft 61 may be performed visually or by checking with an appropriate measuring instrument. However, the thermal printing plate printer 1 according to the present embodiment is A jig (not shown) capable of setting the relative positional relationship between the core shaft 31 and the feed roller shaft 61 in parallel is configured to be mountable.

  The jig includes, for example, a long base portion having a flat plate shape, and a first holding portion and a second holding portion provided at positions separated by a predetermined distance along the longitudinal direction of the base portion. The first holding unit can hold one end of the paper feed core shaft 31, and the second holding unit can hold one end of the feed roller shaft 61. In the present embodiment, both end portions of the paper feed core shaft 31 and both end portions of the feed roller shaft 61 are protruded outward from the standing frame wall 22 (the first standing frame wall 221 and the second standing frame wall 222). In addition, one end of the paper feed core shaft 31 and one end of the feed roller shaft 61 are set so as to be held by the first holding unit and the second holding unit. The axial direction of the feed core shaft 31 held by the first holding unit and the longitudinal direction of the base unit are perpendicular to each other, and the axial direction of the feed roller shaft 61 held by the second holding unit and the base unit The sheet feeding core shaft 31 and the feed roller shaft 61 are parallel to each other so that the longitudinal direction of the sheet is at a right angle. This jig is configured such that at least one of the first holding part and the second holding part is movable in the longitudinal direction of the base part with respect to the base part. This jig can be temporarily mounted before shipment of the thermal printing plate printer 1 or during maintenance.

  As described above, the thermal printing plate printer 1 according to the present embodiment has the paper feed core shaft 31 at one end of the paper feed core shaft 31 at a position where the paper feed core shaft 31 and the feed roller shaft 61 are parallel to each other. A movable adjustment mechanism X capable of adjusting the position of one end of the paper 31 is provided, and by moving one end of the paper feed core shaft 31 by the movable adjustment mechanism X, the paper feed core shaft 31 and the feed roller shaft 61 Can be parallel. As a result, it is possible to prevent the printing plate from being conveyed while being displaced in the width direction with respect to the conveyance direction, and to solve the problem that the printing content (output result) is inclined with respect to the printing plate. The printing process for the printing plate can be performed with high accuracy. When printing is performed on a printed material such as paper using the printed printing plate as an original plate, the print contents (output results) of all the printed materials are not displaced, and a decrease in print quality can be prevented.

  In particular, the movable adjusting mechanism X moves the bearing portion 9 that supports one end of the paper feed core shaft 31 with respect to the standing frame wall 22 (first standing frame wall 221) in the frame body 2 to thereby feed the paper feeding core. Since the position of one end portion of the paper feed core shaft 31 is adjusted to a position where the shaft 31 and the feed roller shaft 61 are parallel to each other, the bearing state of the paper feed core shaft 31 with respect to the bearing portion 9 is improved. If this is maintained, a good bearing state is maintained even when the bearing portion 9 itself is moved with respect to the standing frame wall 22 (first standing frame wall 221), which is preferable. Further, the cause of the deviation in the parallel relationship between the paper feed core shaft 31 and the feed roller shaft 61 is the error in the finished dimensions (working dimensions) and assembly dimensions of the frame body 2. By changing the mounting position of the bearing portion 9 with respect to the upright frame wall 22 (first upright frame wall 221) after processing, an appropriate parallel relationship between the paper feed core shaft 31 and the feed roller shaft 61 is easily ensured. be able to.

The separation distances can be individually adjusted, and by setting these separation distances to be the same, the paper feed core shaft 31 and the feed roller shaft 61 can be kept parallel.

  Further, as shown in FIG. 9, the movable adjustment mechanism X may be provided only at the end of the feed roller shaft 61. Even in this mode, the same effect as that in the mode in which the movable adjustment mechanism X is provided only at the end of the paper feed core shaft 31 can be obtained. Although FIG. 9 shows a mode in which the movable adjustment mechanism X is provided at both ends of the feed roller shaft 61, the movable adjustment mechanism X is provided only at one end of the feed roller shaft 61. It may be an aspect.

  Furthermore, as shown in FIG. 10, a mode in which the movable adjustment mechanism X is provided at both ends of the paper feed core shaft 31 and both ends of the feed roller shaft 61 may be employed. With such an aspect, the distance between one end of the paper feed core shaft 31 and one end of the feed roller shaft 61 and the distance between the other end of the paper feed core shaft 31 and the other end of the feed roller shaft 61. The separation distance can be individually adjusted, and the relative position of the paper feed core shaft 31 with respect to the platen roller 5 and the relative position of the feed roller shaft 61 with respect to the platen roller 5 can be adjusted. By configuring so that the relative positions of the paper feed core shaft 31 and the feed roller shaft 61 with respect to the platen roller 5 can be adjusted, it is possible to suitably correct the printing dimension accuracy (printing position accuracy). A mode in which the movable adjustment mechanism X is provided only at one end of the paper feed core shaft 31 and one end of the feed roller shaft 61, or only at the other end of the paper feed core shaft 31 and the other end of the feed roller shaft 61. A mode in which the movable adjustment mechanism X is provided may be employed.
