Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a stacker for paper sheets discharged from a facsimile machine, a copying machine, etc.

[Technical background of the invention]

Conventionally, in a stacker such as a copying machine, as shown in FIG. A type that receives paper (sheets) below the device main body 1 (hereinafter referred to as vertical stacker 3)
As shown in FIG. 1b, a type of apparatus (hereinafter referred to as a horizontal stacker) in which the main body 1 of the apparatus such as a copying machine is located inside the installation stand 2, and the paper ejected from the apparatus main body 1 is caught on the installation stand. 4).

[Problems with background technology]

In order to prevent the paper from falling off the stacker, the vertical stacker 3 has a paper drop prevention plate 3b attached to the paper stacking plate 3a, and a deep recess is formed between them to catch the paper therein. If this is simply used as a horizontal stacker 4, the falling-off prevention plate 3b becomes an obstacle to paper removal, and on the other hand, the horizontal stacker 4 is not equipped with anything equivalent to the above-mentioned paper falling-off prevention plate 3b. , this cannot be used simply as a vertical stacker 3, so the vertical stacker 3 and the horizontal stacker 4 are
Each was manufactured to different specifications.

[Purpose of the invention] In view of these problems, the purpose of the invention is to
The present invention provides a stacker that can be used both vertically and horizontally as required.Furthermore, another purpose is to hold paper in the horizontal stacker and in the vertical stacker. The present invention provides a stacker for copying machines, etc., which is stacked so that the surfaces thereof are reversed.

[Summary of the invention] In order to achieve such an objective, the present invention provides a guide plate with a guide protrusion separately from the horizontal stacker, and by assembling this to the horizontal stacker, the vertical It is configured so that it can be used as a stacker.

[Example of idea]

The present invention will be described below with reference to embodiments shown in the drawings. Stacker 1 for copying machines, etc. according to the present invention
1 consists of a stacker body 12 used as a horizontal stacker, a guide plate 13, and a fastening means 14 for interconnecting them. The stacker main body 12 has engaging pins 15, 15 disposed on both sides of one end thereof for fitting and engaging with the apparatus main body 1, and has the other end raised to form a paper stopper 16 there. A notch 17 is provided at the center of the end, and several protrusions 18 are formed on one surface toward both ends. The guide plate 13 has a wedge-shaped guide protrusion 19 formed in the center of one surface, has engaging pins 20, 20 arranged on both sides of one end for fitting and engaging with the device main body 1, and further has a wedge-shaped guide protrusion 19 at the center of one side. Several protrusions 21 are formed extending from the guide protrusion 19.
Fastening means 14 between the stacker body 12 and the guide plate 13
is the engagement pin 15,1 in the stacker main body 12.
Holes 22, 22 bored at the end of the 5 side and the guide plate 13
It consists of holes 23, 23 drilled at the opposite ends of the engaging pins 20, 20, and a bolt 24 and a nut 25 that fit into these holes 22, 23 as shown in FIG. . Furthermore, in the embodiment, as shown in FIG.
A recess 2 for accommodating them is located at a position corresponding to 15.
7, 27, 28, 28, and the boss 26,
The engagement pin 15 and the recesses 27 and 28 serve as positioning means when the stacker body 12 and the guide plate 13 are fastened together.

The operation of this embodiment will be explained below. When using the stacker vertically as shown in FIG. and the guide plate 13, and then as shown in FIG.
It is concluded by Clause 5. The stacker 11 assembled in this manner has the engaging pin 20 of the guide plate 13 engaged with the apparatus main body 1, and is suspended from the apparatus main body 1 as shown in FIG. In addition, in Figure 4, 1
A is a paper ejection guide of the apparatus main body 1, and 1b is an ejection roller.

When the paper 5 ejected from between the paper ejection guide 1a and the ejection roller 1b falls into the stacker 11, its lower end hits the guide convex part 19 of the guide plate 13, and falls along the convex part. As shown in Figure 5, along the stacker body 12 of the stacker 11,
It is loaded on top of it. At this time, the guide convex portion 19 of the guide plate 13 has the role of correcting the curvature of the paper 5 that falls in a curved manner, and causes the paper 5 to fall to a predetermined position on the stacker main body.

When using the stacker 11 horizontally as shown in FIG. 1b, the stacker body 12 and the guide plate 13 are separated, and the stacker body 12
Using a chisel, the engaging pins 15, 15 are engaged with the apparatus body 1, and the apparatus is placed on the installation stand 2 as shown in FIG. 1B.

The sheets 5 discharged from between the paper discharge guide 1a and the discharge roller 1b are sequentially stacked on the stacker main body 12 as shown by the two-dot chain line in FIG.

Note that FIG. 5 shows the state of the discharged sheets 5, with the sheets 5 stacked on the stacker main body 12 for horizontal use and the stacker main body 12 for vertical use.
The sheets 5 stacked on the paper 5 have their sides (for example, the copy side) reversed.

[Effect of idea]

As mentioned above, the stacker according to the present invention can be optimally used as either a horizontal stacker or a vertical stacker, and by selecting the mode of use, the stacker can be used to move the desired side of the paper upwards. It can be loaded onto the stacker towards the end.
