At both ends of the support insertion portion 220 in the main scanning direction, support locking portions 222 having a shape extending in the sub scanning direction and protruding outward along the main scanning direction are provided.

  The width of the support insertion portion 220 in the main scanning direction is substantially the same as the width of the support insertion port 123. By inserting the support insertion portion 220 into the support insertion port 123, the support locking portion 222 is inserted. Is locked to the printer main body inside the support insertion port 123, so that the paper support 122 can be maintained attached to the printer main body.

  In the support insertion part 220, the support notch part 221a is formed at a position separated from the center line in the insertion direction of the support insertion part 220 by a distance w (25 mm in this embodiment). The notch 221b is formed at a position away from the center line in the insertion direction of the support insertion part 220 by a distance x (20 mm in this embodiment) on the opposite side of the support notch 221a.

  That is, in the support insertion part 220 of this embodiment, the position where the support notch parts 221a and 221b are formed is different on the left and right from the center line in the insertion direction. For this reason, the positional relationship of the support notches 221a and 221b in the support insertion part 220 changes between the front and back surfaces of the support insertion part 220. As a result, if the front and back sides of the paper support 122 are mistaken, the support protrusions 231a and 231b and the support notches 221a and 221b will not be fitted, and the paper support 122 cannot be mounted. Therefore, the paper support 122 can prevent erroneous mounting due to a wrong front and back.

  As shown in FIG. 8B, the stacker insertion portion 320 has stacker cutout portions 321a and 321b, which are formed in a comb shape.

The notch 321b is formed at a position away from the center line in the insertion direction of the stacker insertion part 320 by a distance z (15 mm in this embodiment) on the opposite side of the stacker notch 321a.

  That is, in the stacker insertion part 320 of the present embodiment, the positions where the stacker cutout parts 321a and 321b are formed are different on the left and right from the center line in the insertion direction. For this reason, the positional relationship between the stacker notch portions 321a and 321b in the stacker insertion portion 320 changes between the front and back surfaces of the stacker insertion portion 320. As a result, if the front and back sides of the stacker 132 are mistaken, the stacker projections 331a and 331b and the stacker notch portions 321a and 321b cannot be fitted, and the stacker 132 cannot be mounted. Therefore, the stacker 132 can prevent erroneous mounting due to a mistake in the front and back sides.

  Further, in the paper support 122 and the stacker 132, the interval between the support notches 221a and 221b is w + x = 25 mm + 20 mm = 45 mm, whereas the interval between the stacker notches 321a and 321b is y + z = 20 mm + 15 mm = 35 mm. , The length is different. Therefore, even if the paper support 122 is to be inserted into the stacker insertion port 132, the length between the stacker projections 331a and 331b is formed to be 35 mm in accordance with the stacker cutouts 321a and 321b. There is nothing. The same applies to the case where the stacker 132 is to be attached to the support insertion port 123.

  As described above, the paper support 122 and the stacker 132 are formed so that the interval between the support cutout portions 221a and 221b and the interval between the stacker cutout portions 321a and 321b are different from each other. It is possible to prevent erroneous mounting due to incorrect mounting.

  Further, the paper support 122 and the stacker 132 of the present embodiment are both plate-like members having a trapezoidal plane and an arc-shaped side surface, and are similar members. The support back surface 122b and the stacker mounting surface 132a are: There is a high possibility that it will be attached by mistake because it is similar. However, in the paper support 122 and the stacker 132, the attachment position and orientation are determined, and the paper support 122 and the stacker 132 are not attached in any other place than the position and orientation. Even with similar shapes, it is possible to reliably prevent erroneous mounting. In addition, it is possible to maintain the sheet conveyance accuracy with high accuracy.

  In the present embodiment, the support notches 221a and 221b and the support protrusions 231a and 231b of the paper support 122, the stacker notches 321a and 321b of the stacker 132, and the stacker protrusions 331a and 331b are provided two by two.
