SOLUTION: A small size printed matter ejection box 14 made of a plastic or a paper is composed mainly of a bottom plate 16 having a cutting part 50; a front plate 18, a rear plate 20, a right side plate 22, and a left side plate 24, and it is positioned by inserting a first insertion piece 52, and a second insertion piece 54, to the clearance of rails on the sheet ejection tale of a printing device. A post card P ejected from the exhaust hole of the printing device advances from a receiving hole 30 and drops down, but the inside of the box has the area a little larger than the post card P, the dropping speed of the post card P is delayed by the air resistance. As a result, the ink drying time can be obtained, and its position slippage is also prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small size printed matter discharge box for storing and stacking small size printed matter such as postcards discharged from a printing apparatus.

[0002]

2. Description of the Related Art FIG. 12 shows a printing apparatus such as a stencil printing apparatus.
As shown in FIG.
02 is formed, and below the discharge port 102, a paper discharge tray (paper discharge tray) 104 is provided. Paper ejection stand 1
04 is provided with an end fence 106 for aligning the leading ends of the printed paper P discharged from the discharge port 102, and side fences 108, 108 for aligning both sides of the paper. Paper P discharged from the discharge port 102
Is an end fence 106 and a side fence 108, 1
08, and they are sequentially loaded. As shown in FIG. 13, the end fence 106 and the side fence 10
8, 8 and 10, respectively, can be position-adjusted in the arrow direction via a rail member or the like (not shown) fixed to the paper discharge tray 104, so that different sizes of paper can be accommodated.

However, it is difficult to accommodate sheets of all sizes, and the end fences 106 and the side fences 108, 108 are actually set to dimensions corresponding to a large group of sheets that are frequently used. There is.
Therefore, the width of the end fence 106, that is, the length in the direction orthogonal to the paper discharge direction is referred to as “minimum length” that does not hinder the leading edge alignment of the largest size sheet of the large size sheet group. Things exist. Postcard (10
When ejecting small size prints such as 0 mm x 148 mm (including both government-made and private-made products), it is necessary to move and adjust each fence to fit the size. Can be adjusted optimally by moving the end fence 106, but the end fence 1
Since the above-mentioned minimum width of 06 exceeds the width of the small-sized printed matter, a gap is inevitably formed between the side fences 108 and 108 in the size in the direction orthogonal to the paper discharge direction.

For this reason, the small printed matter SP that has fallen is apt to shift due to the momentum of landing, as indicated by the chain double-dashed line, and it is difficult to arrange them in an orderly manner. When misalignment occurs, the friction between the previously loaded paper and the later loaded paper becomes severe, and the ink of the previous paper adheres to the back surface of the subsequent paper and stains it, a so-called “offset” problem. I couldn't avoid it. The set-off problem depends on the drying speed of the ink and occurs even if there is no friction due to a positional shift.

In view of such a situation, Japanese Patent Laid-Open No. 8-277
No. 1 gazette discloses that when a small-sized printed matter such as a postcard is discharged, a dedicated storage device is used without using a permanent discharge tray, and the dedicated storage device is used as a permanent discharge tray. A technique is disclosed in which it is mounted on and used without being removed. Since the system is used by mounting it on the paper discharge tray, there is no need to remove the paper discharge tray each time, and there is an advantage that the paper can be taken out better than when the floor type is used. To solve the problem of ink drying, four coil spring-shaped conveyors are installed upright and rotated by a motor, and the printed sheets are raised and stored by spiral moving force without stacking them one by one. Is solved in.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
The technology described in Japanese Patent Publication No. 1 is machined and controlled with an emphasis on the problem of ink drying, and is too automated as a dedicated device for small size printed matter that is rarely used.
It is expensive. In the case of postcards, it is stricter to prevent ink stains on both the front and back sides than other printed materials, so it can be said that the above machine and control are unavoidable in order to eliminate this, but normally used paper discharge There is a strong demand for simplicity, ease of use, and cost reduction comparable to those of a stand.

In order to meet this market demand, the present invention has a simple and simple storage / loading structure dedicated to small-sized printed matter, which has the same level of machine / control structure as that of a discharge tray for normal use. In addition, the purpose is to be extremely inexpensive.

The stencil printing machine 2 shown in FIG. 1 is in a state of use for printing on a postcard, and in response to this, the paper ejection tray 8
Small plastic printed matter output box 1 on top
4 is attached. As shown in FIG. 2, the small-sized printed matter discharge box 14 includes a bottom plate 16 and a front plate 18 as an abutting surface integrally formed vertically on the bottom plate 16.
The rear plate 20, which is integrally formed with the bottom plate 16 vertically on the opposite side of the front plate 18, the right side plate 22, and the left side plate 24.

Hinge shafts 26 and 28 are vertically supported on both sides of the rear plate 20, and the right side plate 22 and the left side plate 24 are provided rotatably outward through the hinge shafts 26 and 28. Has been. Above the rear plate 20, a receiving port 30 for receiving the small size printed matter discharged from the discharging port 4 is formed. The receiving port 30 has a horizontal guide edge 32 that projects toward the discharge port 4 and guides the lower surface of the small-sized printed matter, and vertical guide edges 34 and 36 that also project toward the discharge port 4 and guide both sides of the small-sized printed material. Have Horizontal guide edge 3
2 is integrally formed on the upper end of the rear plate 20, and the vertical guide edges 34, 36 are integrally formed on the right side plate 22 and the left side plate 24. Further, the vertical guide edges 34 and 36 are widened toward the ejection port 4 side so that the ejected paper can smoothly enter even if the posture of the ejected paper is slightly displaced (claims 2 and 3).

Handles 38, 40 for carrying are integrally formed on the right side plate 22 and the left side plate 24, respectively (claim 9). The convex portions 4 are provided on the free ends of the right side plate 22 and the left side plate 24.
2 and 44 are formed. Corresponding to this, the concave portion 4 capable of snap-fitting the convex portions 42 and 44 on the side portion of the front plate 18 is formed.
6, 48 are formed. By this snap fitting,
The right side plate 22 and the left side plate 24 are prevented from opening unexpectedly,
Box shape is maintained. Other magnets, surface fasteners, and the like can be used as the box shape maintaining structure.

A cutout portion 50 is provided on the left side plate 24 side of the bottom plate 16 for facilitating removal of the loaded postcards P.
Are formed. On the lower surface of the bottom plate 16, a first insertion piece 52 as a positioning member protruding downward is integrally formed. Further, a second insertion piece 54 is integrally formed on the front plate 18 side of the bottom plate 16, and the second insertion piece 54 is formed.
Is composed of a T-shaped horizontal portion 54a and two vertical portions 54b.

As shown in FIGS. 3 and 4, the paper ejection tray 8 is provided with a rail member 56 for moving the end fence 10 and a rail member 58 for moving the side fences 12, 12. Therefore, a gap C exists between the rail member 56 and the rail member 58 on both sides of the rail member 56 and the rail member 58, respectively. The first insertion piece 52 is inserted into these gaps C.
By inserting the vertical portion 54b of the second insertion piece 54 and the second insertion piece 54, the small size printed matter discharge box 14 is positioned with respect to the discharge table 8 and the discharge port 4 (claim 4,
5).

As shown in FIG. 5, the bottom plate 16, the front plate 18,
A space surrounded by the rear plate 20, the right side plate 22, and the left side plate 24 serves as a storage unit 60 in which the postcards P are stored and loaded, and the storage unit 60 has an area set to be slightly larger than the area of the postcards P. Specifically, the gap S is 1 mm to 5 m
It is about m (claim 1).

Although not shown in FIG. 1 and the like, as shown in FIG. 6, a thin sponge 62 is attached to the inside of the front plate 18 to form a high friction surface (claim 8). ). The postcard P discharged from the discharge port 4 of the stencil printing machine 2 enters the storage part 60 from the receiving port 30, but hits the front plate 18 with its tip inclined downward. As described above, since the high friction surface exists at the abutting portion of the front plate 18, the tip of the postcard P is temporarily caught on the high friction surface,
During this time, the rear end falls. For this reason, the postcard P falls with its posture adjusted substantially horizontally.

In this case, since the area of the storage section 60 is only slightly larger than the area of the postcard P as described above, there are very few escape paths for the air in the storage section 60 that is compressed by the falling of the postcard P, and the postcard P is small. Air resistance AR on the underside of
Works. As a result, the falling speed of the postcard P is reduced, the time for drying the ink is secured, and the set-off is prevented. Further, when the postcard P is dropped, there is almost no misalignment, and there is no friction between the preceding paper and the following paper, and thus offsetting is prevented also from this point. Therefore,
It is possible to prevent set-off by an extremely simple structure without using a mechanical / control structure.

In the case of "storing and stacking small-sized printed matter on the discharge tray 8" described in the prior art,
Even if the size of the end fence 106 matches the size of the small size printed matter, the end fence 106
Since the enclosed space including the side fences 108 and 108 is an open space, it is extremely unlikely that the drop speed will be slowed by the air resistance, and the settling time will eventually occur because the ink drying time cannot be obtained. .

When the inside of the storage unit 60 is filled with postcards P or when a predetermined amount is loaded, the right side plate 22 and the left side plate 24 are rotated to secure a take-out space, and the cutout portion 50 is used. Take out a bundle of postcards P. Paper ejection table 8
If the postcard P is not taken out above, the handles 38, 40
The small-size printed matter discharge box 14 is lifted by, the first inserting piece 52 and the second inserting piece 54 are pulled out, and after moving to a predetermined place, the above-mentioned taking out is performed. In this embodiment, since both the right side plate 22 and the left side plate 24 are rotatably provided, a wide take-out space can be obtained and the take-out is extremely easy. However, only the left side plate 24 on the cutout portion 50 side is rotated. It may be configured to move (claims 10 and 11). Further, as shown in FIG. 7, only the front plate 18 may be rotatable, and the notch 50 may be formed correspondingly.

In the above embodiment, the whole is made of plastic, but it may be made of cardboard or cardboard. In this case, the cost can be further reduced. As the high-friction surface, in addition to the sponge 62, various things such as a rubber sheet and sandpaper can be adopted. As shown in FIG. 8, the positioning member may be configured such that, instead of the second insertion piece 54, insertion pieces 64, 64 are provided on both sides of the bottom plate 16. In this case, the insertion pieces 64, 64 are fixed by sandwiching the rail member 58 by the slider 66 that moves. As shown in FIG. 9, when the attachment portion of the paper ejection tray 8 is made of metal, the magnet 68 may be fixed to the lower surface (bottom surface) of the bottom plate 16 and positioned by magnetic force (claim 6). ). Figure 1
As shown in 0, when the attachment part of the paper discharge tray 8 is a smooth surface, the suction cup 70 may be fixed to the bottom surface and positioned by the suction force (claim 7). When the whole or a part is formed of a heavy material such as iron, the positioning can be performed by simply sticking a non-slip material such as a rubber plate on the bottom surface. The handles 38 and 40 may be formed as holes in the right side plate 22 and the left side plate 24, respectively, as shown in FIG.

[0031]

According to the first aspect of the present invention, small-sized printed matter such as postcards can be stored and loaded without causing positional displacement, and the drop speed can be slowed down. It is possible to solve the set-off problem with a simple and inexpensive structure without needing to do so.

According to the second or third aspect of the present invention, even if the position of the sheet discharged from the discharge port of the printing apparatus is deviated, it can be surely guided into the box by the guide edge.

According to the fourth aspect of the present invention, since the positioning member is provided for the paper discharge table, the positional relationship with the discharge port can be stabilized throughout the printing operation.
