A pair of guide plates 3 and 4 that are positioned at opposite ends of the support plate portions 11 and 21 across the path P1 and that guide both sides in the width direction of the recording medium having a width w2 that is transported through the transport path P2. The guide plate portions 32 and 42 are configured to be positioned at opposite ends of the support plate portions 31 and 41 with the conveyance path P2 interposed therebetween.

  Among these guide members 1 to 4, the guide member 1 located at the right end in FIG. 1 is fixed to a predetermined reference position by fixing means such as a screw with respect to the attachment member 5, and the attachment member 5 is immovable.

  On the other hand, the guide members 2 and 3 located in the middle are detachable from the attachment member 5. The guide members 2 and 3 can be adjusted in position along the width direction of the recording medium, which is a preferable aspect of the present invention.

  FIG. 3 is an overall perspective view showing a state in which the guide members 2 and 3 are removed from the attachment member 5. As shown in the figure, the guide members 2 and 3 are attached to the attachment member 5 via the slide members 6 and 7.

  The slide members 6 and 7 include support portions 61 and 71 that support the back surfaces of the guide members 2 and 3 and four leg portions 62 and 72 that protrude further from the support portions 61 and 71 to the back surface side. Each of the leg portions 62 and 72 is inserted into two parallel restriction grooves 51 and 52 that are formed in the attachment member 5 so as to extend horizontally along the width direction of the recording medium. The stopper members 63 and 73 are attached to the leg portions 62 and 72 so as to sandwich the attachment member 5 therebetween.

  Details of the stopper members 63 and 73 are shown in FIG. The stopper members 63 and 73 are fixing plates 632 and 732 that are fixed to the leg portions 62 and 72 of the slide members 6 and 7 by screws 631 and 731, respectively, and fixed that rise from the mounting plates 632 and 732 at a substantially right angle. Pieces 633 and 733.

  Each of the fixed pieces 633 and 733 has movable pieces 635 and 735 that are pivotally attached by shafts 634 and 734, and on the tip side between each of the fixed pieces 633 and 733 and each of the movable pieces 635 and 735, Biasing springs 636 and 736 are interposed to bias the ends of the fixed pieces 633 and 733 and the movable pieces 635 and 735 in directions away from each other about the shafts 634 and 734.

  In FIG. 4, the stopper member 73 shows a state in which no external force is applied between the fixed piece 733 and the movable piece 735, and the stopper member 63 includes the tips of the fixed piece 633 and the movable piece 635. Is shown in a state where the operator or the like is operated so as to be pinched with a finger against the biasing spring 636.

  When the fixed piece 633 and the movable piece 635 are operated so that the tips of the fixed piece 633 and the movable piece 635 are sandwiched against the biasing spring 636 closer to the mounting plate 632 side than the shaft 634. , Openings 637 and 638 having shapes matching each other when viewed from the width direction of the recording medium (left and right direction in FIG. 4) are formed, and the fixed piece 733 and the movable piece 735 are also attached to the mounting plate rather than the shaft 734. When viewed from the width direction of the recording medium (left and right direction in FIG. 4) when the distal ends of the fixed piece 733 and the movable piece 735 are operated to be sandwiched against the biasing spring 736 on the 732 side. Openings 737 and 738 having shapes matching each other are formed.

  These openings 637, 638, 737, and 738 are formed to be substantially the same size, and are provided along the width direction across the openings 637, 638, 737, and 738 on the back surface side of the attachment member 5. One guide bar 8 is inserted. The guide bar 8 is slightly smaller in diameter than the openings 637, 638, 737, 738.

  Therefore, as in the stopper member 63 in FIG. 4, when an operator or the like is held between the tips of the fixed piece 633 and the movable piece 635 against the biasing spring 636 by the finger, the opening of the fixed piece 633 is opened. 637 and the opening 638 of the movable piece 635 coincide with each other, and are slidable along the guide rod 8. At this time, the slide member 6 slides in the width direction of the recording medium while the leg portion 62 is regulated along the regulation groove 51. Thereby, the position of the guide member 2 attached to the slide member 6 is adjusted along the width direction of the recording medium.

  Further, like the stopper member 73 in FIG. 4, in the state where no external force is applied to the fixed piece 733 and the movable piece 735, the tip of the movable piece 735 is moved from the fixed piece 733 by the biasing force of the biasing spring 736. It rotates about the shaft 734 so as to separate. As a result, the movable piece 735 changes its angle with respect to the guide bar 8 as shown in the partially enlarged view of FIG. 5, and the apparent shape of the opening 738 of the movable piece 735 is the opening when viewed from the width direction of the recording medium. It becomes narrower than 737, and the inner edge e of the opening 738 is pressed so as to sandwich the guide bar 8 from the opposite direction, thereby disabling sliding movement along the guide bar 8. Accordingly, the slide member 7 is prevented from moving along the width direction of the recording medium, and the guide member 3 attached to the slide member 7 is once positioned at the position along the width direction of the recording medium.

  The slide members 6 and 7 that are slidable along the width direction of the recording medium in this way have a wide groove 64 along the recording medium conveyance direction at the approximate center of the support portions 61 and 71. 74 and narrow grooves 65 and 75 continuous to the wide grooves 64 and 74 are formed so as to penetrate therethrough, and projecting portions 66 and 76 projecting laterally are formed on the left and right sides of the support portions 61 and 71, respectively. Has been.

  On the other hand, FIG. 6 shows details of the guide members 2 and 3 detachably attached to the slide members 6 and 7. Since the guide members 2 and 3 have the same symmetrical structure, the guide member 2 is shown in FIG. 6, and the reference numerals corresponding to the guide member 3 are shown in parentheses.

  In the guide members 2 and 3, the engagement plate portions 24 having substantially the same width as the wide grooves 64 and 74 are interposed via the engagement legs 23 and 33 having substantially the same width as the narrow grooves 65 and 75 of the slide members 6 and 7. , 34 project from the back side of the support plate portions 21 and 31 so as to form a T shape.

  Further, on the left and right side portions of the support plate portions 21 and 31, the locking claws 25 and 35 for locking to the overhang portions 66 and 76 of the slide members 6 and 7 along the recording medium conveyance direction. Is formed, and is connected to the support plate portions 21 and 31 by the mounting leg portions 26 and 36 at a substantially central portion thereof.

  The guide members 2 and 3 are generally integrally formed of synthetic resin. After the engagement plate portions 24 and 34 are fitted into the wide grooves 64 and 74 of the slide members 6 and 7, the guide members 2 and 3 are directed downward in the figure as they are. Slide the engagement legs 23 and 33 into the narrow grooves 65 and 75 of the slide members 6 and 7, and at the same time, using the elasticity of the synthetic resin, the tips of the locking claws 25 and 35 The claw portions 251 and 351 of the slide member 6 and 7 are attached to the slide members 6 and 7 by getting over the overhanging portions 66 and 76 of the slide members 6 and 7 and engaging with them.

  In addition, when removing, the nail portions 251 and 351 at the front end are expanded to the left and right with the mounting legs 26 and 36 as the center by picking the rear ends 252 and 352 of the respective locking claws 25 and 35. The guide members 2 and 3 are removed by opening and releasing the latched state of the projecting portions 66 and 76 of the slide members 6 and 7 and then sliding them upward in the figure and performing the reverse operation to the above. Can be done.

  The guide member 4 located at the left end portion in FIG. 1 has four leg portions 43 protruding to the back side of the support plate portion 41, and the leg portions 43 are attached to the attachment member 5 as the width of the recording medium. A stopper member 44 is inserted into the leg portion 43 so as to be inserted through two parallel restriction grooves 53 formed so as to penetrate horizontally in the direction and sandwich the attachment member 5 therebetween on the back surface side of the attachment member 5. It is attached.

  The structure of the stopper member 44 is the same as that of the stopper members 63 and 73 shown in FIG. 4, and the guide rod 8 is inserted into the opening in the same manner as these, so that the same movement as the stopper members 63 and 73 is made. . Accordingly, the position of the guide member 4 can be adjusted along the width direction of the recording medium, just like the guide members 2 and 3.

  Further, as shown in detail in FIG. 7, the guide member 4 is provided with a locking member 45 on the same substrate as the substrate 441 to which the stopper member 44 is attached on the back surface side of the attachment member 5. The locking member 45 has a locking plate piece 451 having a width that matches the longitudinal slit 54 along the recording medium conveyance direction at a predetermined position of the mounting member 5, and has an axis along the width direction of the recording medium. After the guide member 4 is adjusted so that the position of the locking plate piece 451 and the position of the slit 54 coincide with each other, the locking plate piece 451 is rotated, By fitting the tip into the slit 54, the guide member 4 can be positioned at the position (reference position) where the slit 54 is formed (FIG. 7A).

  Further, when the locking plate piece 451 is rotated and removed from the slit 54, the fixed state of the guide member 4 with respect to the mounting member 5 is released, and the stopper member 44 is operated to move along the width direction of the recording medium. Position adjustment can be performed arbitrarily (FIG. 7B).

  Thus, according to the transport guide apparatus, as shown in FIG. 1, when the recording media having the widths w1 and w2 are transported in parallel in two rows on the transport paths P1 and P2, the guide member 1 is attached to the mounting member 5 as shown in FIG. Is fixed at the reference position, and the position of the guide member 2 that forms a pair with the reference position is adjustable, so that the position of one side of the recording medium conveyed along the conveyance path P1 is fixed at the reference position. At the same time as being regulated by the guide member 1, the position of the other side is also regulated by adjusting the position of the guide member 2 to the recording medium width. Thereby, the positions of both sides of the recording medium having the width w1 conveyed along the conveyance path P1 can be regulated by the guide members 1 and 2, and the conveyance can be guided.

  Further, when the locking plate piece 451 of the guide member 4 is rotated and fitted into the slit 54 and positioned, the guide member in which the position of one side portion of the recording medium transported along the transport path P2 is positioned at the reference position. At the same time, the position of the guide member 3 paired with the guide member 3 can be adjusted, so that the position of the other side portion is also regulated by adjusting the position of the guide member 3 to the recording medium width. As a result, both side portions of the recording medium having the width w2 conveyed along the conveyance path P2 can be regulated by the guide members 3 and 4, and the conveyance can be guided.

  Next, when only one row of the recording medium having the maximum width w3 is transported, the guide members 2 and 3 positioned in the middle are removed from the slide members 6 and 7 as shown in FIG. A wide conveyance path P3 is formed between 1 and 4. At this time, since the one guide member 1 is fixed at the reference position with respect to the attachment member 5, the guide member 1 regulates the position of one side portion of the recording medium, and at the same time, the locking plate piece of the guide member 4. After the 451 is rotated to release the locked state with the slit 54, the stopper member 44 is operated to adjust the position of the guide member 4 to the width of the recording medium, thereby restricting the position of the other side of the recording medium. As a result, both side portions of the recording medium having the width w3 can be regulated by the guide members 1 and 4, and the conveyance thereof can be guided.
