And
[0023]
The recycle bin 20 has a storage space as large as the size of a stencil sheet, and is composed of a recycle bin main body 21 opened at the top and a cover 22 arranged so as to cover the top of the recycle bin main body 21. The cover 22 is detachably attached to the trash box main body 21. An opening 23 is provided over substantially the entire area of one side of the cover 22 and a part of the upper surface, and this opening 23 is for allowing the rotation of the rotation guide member 24.
[0024]
A rotation guide member 24 is rotatably supported around each support pin 25 inside the cover 22, and the rotation guide member 24 is a box insertion position (position of FIG. 2) for inserting the discharge box main body 2 in a horizontal state. And a tilting position (position in FIG. 3) at which the discharge box main body 2 is tilted at a substantially right angle. On the surface of the rotation guide member 24 in which the opening 23 of the cover 22 is provided, a box insertion opening 26 for inserting the discharge box main body 2 is provided. The rotation guide member 24 holds the discharge box 1 inserted into the box insertion opening 26, and the upper opening 5 of the discharge box body 2 can be rotated in the downward direction while holding the discharge box 1. Yes. A torsion spring (biasing means) 27 is interposed between the rotation guide member 24 and the cover 22, and the plate discharging box body 2 is moved to the box insertion position (position in FIG. 2) side by the spring force of the torsion spring 27. It is energized.
[0025]
The cover 22 is provided with a stopper portion 28, and the leading end of the base paper expansion pressing member 7 of the stencil box 1 inserted into the box insertion port 26 is positioned above the stopper portion 28. The stopper portion 28 prevents the base paper expansion pressing member 7 from rotating together with the plate discharging box main body 2 when the plate discharging box main body 2 is guided and rotated by the rotation guide member 24.
[0026]
Next, the operation of the above configuration will be described. When the stencil sheet stored in the base paper storage space 4 of the stencil box 1 is full, the user removes the stencil box 1 from the printing apparatus main body. The removed box 1 is transported to the position of the trash box 20 and inserted into the box insertion opening 26 of the trash box 20. As shown in FIG. 2, when the discharge box 1 is completely inserted into the box insertion opening 26, the tip of the base paper expansion pressing member 7 of the discharge box 1 is positioned in the vicinity of the stopper portion 28.
[0027]
Next, when the user applies a rotational force to the handle 3 of the discharge box 1 and rotates the discharge box 1 in the direction of the arrow in FIG. 2, the discharge box main body 2 rotates while being held by the rotation guide member 24. By this rotation, the upper opening 5 of the discharge box body 2 is gradually inclined downward. The rotation of the discharge box main body 2 also attempts to rotate the base member expansion pressing member 7 and the integrated member 8 of the scraping member 6. However, since the rotation of the base paper expansion pressing member 7 is blocked by the stopper portion 28, the base paper expansion pressing member 7. And the integral member 8 of the scraping member 6 maintains its position without rotating. In other words, the integrated member 8 of the base paper expansion pressing member 7 and the scraping member 6 does not rotate while the plate discharging box main body 2 rotates, so that the relative displacement of the base paper expansion pressing member 7 and the base paper expansion pressing member 7 causes the base plate expansion pressing member 7 to move as shown in FIG. While moving gradually away from the position of the upper opening 5 of the main body 2, the scraping member 6 changes from the innermost position of the discharge box main body 2 to the position of the upper opening 5.
[0028]
Here, the base paper expansion presser member 7 that has restricted the upper opening 5 of the discharge box main body 2 is separated from the upper opening 5, and the scraping member 6 is moved from the deepest position of the discharge box main body 2 to the position of the upper opening 5. When shifting toward the stencil sheet, the scraping member 6 separates the stencil sheet adhering to the stencil box body 2 due to the adhesiveness of the ink, and forcibly moves the stencil sheet up to the upper opening 5 of the stencil box body 2. Is discharged from the upper opening 5.
[0029]
Since the stencil sheet discharged from the stencil box body 2 is discharged into the cover 22 of the trash box 20, the stencil sheet is discharged into the trash box body 21 even if the stencil sheet is expanded from the stencil box body 2. As described above, the stencil sheet in the stencil box 1 can be easily discarded into the trash box 20 which is not larger than the size of the stencil sheet. After discarding the stencil sheet, the discharge box body 2 is returned to the original rotational position, the discharge box 1 is pulled out from the box insertion port 26, and the extracted discharge box 1 is mounted on the printing apparatus main body again.
[0030]
In this embodiment, since the scraping member 6 is provided on the side of the plate discharging box 1, the scraping member 6 is easily changed from the innermost position of the plate discharging box body 2 to the position of the upper opening 5 during the relative rotation of the plate discharging box body 2. advantage of being able to be there Ru.
[0031]
In this embodiment, the scraping member 6 is rotatably provided in conjunction with a base paper expansion pressing member 7 that is positioned in the upper opening 5 of the main plate box 2 and prevents the expansion of the stencil base paper housed therein. When the box body 2 is inserted into the box insertion port 26 of the trash box 20 and rotated, the base paper expansion pressing member 7 contacts the stopper portion 28 on the trash box 20 side, and the scraping member 6 is prevented from rotating together with the base paper expansion pressing member 7. Therefore, since the stencil sheet in the stencil box body 2 is expanded by the stencil sheet expansion pressing member 7 when the stencil box 1 is taken out from the printing apparatus body, the stencil sheet can be transported from the mounting position of the printing apparatus body to the trash box 20. It is possible to prevent the stencil sheet from popping out from the upper opening 5 due to expansion. Further, since the base paper expansion pressing member 7 also serves as a rotation preventing means when the discharge plate box body 2 is rotated, the number of parts is reduced.
[0032]
In this embodiment, since the scraping member 6 and the base paper expansion pressing member 7 are integrally formed as the integrated member 8, there is an advantage that the scraping member 6 and the base paper expansion pressing member 7 can be easily linked.
[0033]
In this embodiment, the rotation guide member 24 is biased by the torsion spring 27 toward the box insertion position where the plate removal box 1 is inserted. Therefore, when the plate removal box 1 is not inserted, the rotation guide member 24 is torsion spring. When the discharge plate main body 2 is inserted by the spring force of 27, the base paper expansion pressing member 7 is reliably positioned at a position where it interferes with the stopper portion 28. 6 can be reliably changed from the innermost position of the plate-release box main body 2 to the position of the upper opening. That is, since the rotation guide member 24 returns to the original position regardless of the rotation position at which the discharge box main body 2 is pulled out from the rotation guide member 24, the disposal operation of the next stencil sheet is easy.
[0034]
