DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stacker provided for receiving a sheet medium (processed paper) continuously sent from an apparatus for transferring and reading information, and more particularly to a stacker provided in a substantially horizontal direction. The present invention relates to a stacker with a sheet stopper suitable for receiving a sheet sent to a stacker.

[0002]

2. Description of the Related Art Printers for transferring and reading information, O
The direction in which processed paper is discharged from a CR device, a facsimile device, or the like is roughly classified into a vertical direction and a substantially horizontal direction. The stacker that receives the paper discharged in the vertical direction has a bottom plate that supports the lower side of the paper and a back plate, and has an L-shape with an inclined side surface. In the stacker having such a structure, it is possible to receive sheets of various sizes by providing a back plate having a size corresponding to the maximum size of the sheet to be used.

[0003] On the other hand, when the paper is sent in a substantially horizontal direction, the paper can be received by a mere flat stacker plate or stacker cage when the paper sending speed is low.
In this case, the stacker plate or stacker cage needs to have a size corresponding to the maximum size of the paper to be used, but in order to save the installation space of the device, a metal wire stacker plate is attached to the tip of the synthetic resin stacker plate. The stacker cage is stretchably mounted, and when the paper to be used is small, the stacker cage is pushed in, and when the paper to be used is large, the stacker cage is pulled out to enlarge the receiving area of the stacker. .

[0004] However, if the paper sending speed is increased due to the improvement of the information transfer speed and the reading speed, the paper is scattered without stopping at a fixed position in a mere flat stacker, and the stacking property is extremely deteriorated. In order to avoid this, for example, a stacker with a paper stopper as shown in FIG. 10 is used.

The stacker shown in FIG. 10 has a stacker plate 7 on the base end side and a stacker cage 8 on the front end side slidably mounted on the stacker plate 7 in the sheet feeding direction. Both the plate 7 and the stacker cage 8 are made of a flat resin molded product. The stacker cage 8 includes a comb-like guide plate 81 extending toward the stacker plate 7, and is slidably supported by the stacker plate 7 on the side of the guide plate 81. On the upper surface of the stacker cage 8, a paper stopper 9 made of a plate-shaped synthetic resin molded product is mounted so as to be able to be turned upside down. In the stacker shown in FIG.
The paper stopper 9 is pivotally supported on a base side 91 thereof, and stands up by raising a front side 92 upward. Normally, the upright state of the sheet stopper is held by a not-shown locking piece utilizing the elasticity of the resin. For the size of the paper sent out,
The position of the paper stopper 9 with respect to the stacker plate 7 is changed by sliding the stacker cage 8 relative to the stacker plate 7 in the paper sending direction.

[0006]

However, in the conventional stacker in which the paper stopper 9 is provided in the structure as shown in FIG. 10, the moving stroke of the paper stopper is not sufficient, and the minimum required for the information transfer device and the reading device is used. It was not possible to handle paper from the size to the maximum size. At the information processing site, sheets from A8 portrait to A3 portrait are processed on a daily basis, but the expansion stroke of the stacker cage 8 is determined by the length L of the stacker plate 7 (length in the paper sending direction). Since the movement stroke of the paper stopper 9 is shorter than the length of the stacker plate 7, the position of the paper stopper can be set so as to correspond to a wide range of paper as described above. It was impossible.

In the structure shown in FIG. 10,
There is also a problem that three resin molded products are required, and the cost of the mold increases.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems and to provide a stacker with a paper stopper which enables the paper stopper to be set for a wider range of paper and can be manufactured at lower cost. It is an issue.

[0013]

According to the first structure of the present invention, the sheet stopper 3 is connected to the frame edge 2 of the stacker cage.
1 to move the stacker cage 2 forward and backward with respect to the stacker plate 1 so as to cope with large-sized paper. On the other hand, when the size of the paper is small, the paper stopper 3
Is fitted to the side edge 11 or the ridge 15 of the stacker plate and slid along the side edge or the ridge to set the paper stopper 3 according to the paper size. That is, this first
When the paper used is small,
The paper stopper 3 is fitted to the side edge 11 of the stacker plate 1 for use. When the paper size is large, the paper stopper 3 is fitted to the stacker cage 2 pulled out from the stacker plate 1 for use. Regardless of whether the paper stopper 3 is mounted on the stacker plate 1 or the stacker cage 2, the mounting position can be freely moved and set within the range of the length of those members. It can correspond to paper.

The second aspect of the present invention according to claim 3 or 4 is as follows.
When the paper size is short, the L-shaped portion 61 of the stacker cage is pivoted upward around its joints 54, 57, 58 so that the leading edge 62 of the paper stopper is
Alternatively, it is used in a state of being in contact with the slide portion 51 of the stacker cage. In the configuration in which the intermediate portion 59 is provided in the stacker cage 5 and the knot portions 57 and 58 are provided at two positions, the intermediate portion 59 and the L-shaped portion 61 are provided around the knot portion 57 on the base end side for small-sized paper. When the paper is of an intermediate size, only the L-shaped portion 61 is used by rotating upward around the knot portion 58 on the leading end side. In this case, the joints 57 and 58 have a structure in which the tip end of the stacker cage 5 can rotate only upward. Therefore, even if the tip end is rotated around any joint, the other joints are stacked. Since the weight of the cage acts in the direction in which the cage cannot rotate, bending at the other node is prevented.

For paper in a range where the paper size is small,
By rotating the L-shaped portion 61 of the stacker cage upward and moving the slide portion 51 of the stacker cage forward and backward with respect to the stacker plate 4, the position of the sheet stopper 6 is set according to the size of each sheet. If the paper size is large,
The L-shaped portion 61 of the stacker cage is used while being extended without rotating upward, and the slide portion 51 of the stacker cage is moved forward and backward with respect to the stacker plate 4 so that the sheet stopper 6 is positioned at a position corresponding to each sheet size. Set.

FIGS. 5 and 6 show a second embodiment of the present invention. The stacker according to the second embodiment includes a stacker plate 4 made of a resin molded product and a stacker cage 5 made of a metal wire. The stacker cage 5 has the same structure as that of the first embodiment, and is formed of a slide portion 51 and an L-shaped portion 61 slidably supported by the stacker plate 4, and the tip of the slide portion 51 and the base of the L-shaped portion 61. The ends are rotatably connected by pins 52 in the width direction of the sheet to be fed, and the L-shaped portion 61 is rotated downward beyond the extended position by a stopper 53 provided by extending one of the ends. Has been blocked.

Here, the extended position is a position where the base end of the L-shaped portion 61 and the slide portion 51 are in a straight line when viewed from the side, as indicated by the imaginary line on the right side of FIG. Part 61
Is rotatable around the pin 52 only above the extended position (counterclockwise in FIG. 6). As shown in FIG. 6, the L-shaped portion 61 has an L-shape when viewed from the side, and the portion that rises upward at the extended position is the paper stopper 6.

When the size of the sheet to be sent out is small, the L-shaped portion 61 is pivoted upward around the pin 52 to move the leading edge 62 of the sheet stopper to the upper surface of the stacker plate 4 (solid line in FIG. 6) or the stacker. It is used in a state of being in contact with the upper surface of the slide portion 51 of the cage (the imaginary line in the center of FIG. 6). The position of the paper stopper 6 is set by expanding and contracting the slide portion 51 of the stacker cage relative to the stacker plate 4 with respect to the size of the sent paper. In this state, the paper stopper 6 is moved by the expansion and contraction of the slide portion 51 as shown in FIG.

The non-settable area S3 can be reduced by increasing the stroke of the slide portion 51 with respect to the stacker plate 4, but the following structure can be adopted as a structure for eliminating the non-settable area.

In the first structure, an auxiliary stopper 64 as shown in FIG. 7 is prepared, and when the sheet size is in a range where the sheet stopper cannot be set, the auxiliary stopper 64 is used in the first embodiment. Like the paper stopper 3 shown in the example, the paper stopper 3 is fitted to the frame edge of the stacker cage and stands upright. When the auxiliary stopper 64 is not used, as shown by an imaginary line in FIG. 6, the auxiliary stopper 64 can be locked to the stacker cage 5 by the fitting portion 65 at the base end and the hook 66 at the distal end.

In the second structure, as shown in FIG. 8, a notch 42 is provided in the tip side 41 of the stacker plate, and a knot portion 54 between the slide portion 51 and the L-shaped portion 61 of the stacker cage is cut. In this structure, the stroke of the stacker cage 5 with respect to the stacker plate 4 is increased so as to enter the stapler 42. In this case, the members 55 and 56 (see FIG. 5) in the paper width direction provided on the slide portion of the stacker cage are deflected so that the positions of these members 55 and 56 are shifted downward so as not to interfere with the stacker plate 4. is necessary.

The third structure is to provide two knot portions of the stacker cage as shown in FIG. Each of the two joints 57 and 58 has a structure in which a member on the tip side can rotate only upward. The stacker cage 5 is divided into three parts, a slide part 51, an intermediate part 59, and an L-shaped part 61, by the two joint parts 57, 58. When the paper size is short, as shown in FIG. 9 (a), the L-shaped portion 61 and the intermediate portion 59 are rotated upward around the base end side nodal portion 57, and the leading edge 62 of the paper stopper is rotated. Is used in a state of contacting the upper surface of the stacker plate 4. When the paper size is an intermediate size, the L-shaped portion 61 is rotated upward around the knot portion 58 on the front end side, as shown in FIG. Is used in a state in which it is in contact with the upper surface of the stacker or the upper surface of the slide portion 51 of the stacker cage. When the size of the sheet to be used is large, the intermediate portion 59 and the L-shaped portion 61 are used in an extended state as shown in FIG.
