Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a paper storage box in which paper (for example, line printing paper) discharged from a printing device after printing is folded and stacked alternately front and back.

Conventionally, a paper storage box 1 for storing paper 4 printed by a printing device 20 has a receiving plate 3 supported by an elastic body 2 (for example, a spring) inside, as shown in FIGS. 1 and 2. Paper 4 stacked and stored on this receiving plate 3
The receiving plate 3 was configured to descend in proportion to the amount of.

In this case, as shown in FIG. 3, if paper with different thicknesses at one end 4cL and the other end 4b of the printing paper is used, such as multi-copy paper with one end glued, paper 4
As the sheets are stacked in the paper storage box 1, the stacking surface 7 gradually tilts with the thicker end of the paper facing up, and the gap 8 between the paper ejection position and the stacking position becomes thicker. The prior art has the problem that the paper 4 is twisted, wrinkles are generated on the paper surface, and the resulting paper is not folded.

The present invention is intended to solve the above-mentioned problems, and when printing paper whose thickness at one end is different from the thickness at the other end is used, the paper surface to be stacked is lowered so that it does not tilt more than a certain angle. An object of the present invention is to provide a paper storage box having a receiving plate.

Next, one embodiment of the present invention will be described using the drawings.

In FIG. 4, 1 is a paper storage box 1 that stores paper 4;
3 is a receiving plate 9 and 10 for receiving the ejected paper 4; one end of the receiving plate 3 is fixed to the bottom surface 11 of the box-shaped container 1 with screws; the other end is fixed to the bottom surface 11 of the box-shaped container 1; 12 is a presser for fixing the coil spring; 13 is a stopper for determining the final lowering position of the receiving plate 2; and 14 is a hook for fixing the paper storage box 1 on the image side. The paper storage box according to the present invention is constructed as described above, and its operation will be explained in order below.

Paper 4 discharged from the printing device 1 after printing is folded and stacked on the receiving plate 3, and coil springs 9 and 10 support the receiving plate 3 in proportion to the weight of the paper.
It sways. The receiving plate 3 descends as the sheets 4 are stacked, and finally hits the stopper 16 and stops descending.

When the spring constants of coil springs 9 and 10 are equal,
If the mounting parts of the coil springs 9 and 10 are set in positions that are not symmetrical with respect to the center of gravity when a predetermined amount of paper is stacked, the amount of deflection of the coil spring 10 that is closer to the center of gravity is large, so that the receiving plate 3 will not be able to accommodate the stack of paper. According to the
Hairs are formed that descend with increasing inclination. Therefore, as shown in FIG.
As shown in FIG. 6, the amount of inclination 15 of the stacking surface when a predetermined amount of paper 4 is stacked, and the amount of inclination 16 of the receiving plate when a predetermined amount of paper is stacked on the receiving plate 2. When matching mK and mounting positions of the coil springs 10 and 9 are selected, the receiving plate 3 is lowered so that the surface 7 of the sheets to be stacked does not incline beyond a certain angle. Therefore, as shown in Fig. 3, the deviation between the ejection position and the stacking position of the paper 4 can be reduced to a small amount of 8, which reduces the twist of the paper 4 and reduces the occurrence of wrinkles on the paper surface. Therefore, it does not interfere with the folding of the paper.

In the above explanation, an example was explained in which coil springs with the same spring constant are placed in positions that are not symmetrical with respect to the center of gravity when a predetermined amount of paper is stacked. A method may be used in which one spring Mu of the coil springs arranged at the same position is replaced with the other spring.

As is clear from the description of the embodiments described above (according to the present invention, when printing paper with different thicknesses at one end and the other end is used, the receiver in the paper storage box The board tilts and descends according to the amount of paper being folded, and the stacking surface can be kept from tilting beyond a certain angle at all times, without interfering with normal folding and stacking of paper, and furthermore Since the mounting position of the supporting coil spring can be selected, the same effect can be obtained for other printing papers whose stacked surfaces have different inclinations when a predetermined amount of papers are stacked.
