Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a paper loading table for an automatic paper feeder.
In particular, it relates to a paper loading table for an automatic paper feeder installed in a card reader or the like.

[Conventional technology]

An example of an automatic paper feeder commonly used in card readers and the like is shown in FIG. In this figure, reference numeral 1 indicates a sheet such as a check, and reference numeral 2 indicates a paper loading table on which the sheet 1 is temporarily placed upright before being fed out. A paper feeding mechanism 3 is provided below the paper loading table 2 in FIG. A back plate 4 for pressing the seat is provided to allow the seat to move.

The paper feed mechanism 3 includes a pick-up section 5 that pulls out and sends out the sheet 1 from the paper loading table 2 described above by the frictional force of a pick-up roller 5A, and a pick-up section 5 that pulls out and sends out the sheet 1 from the above-mentioned paper loading table 2 by the frictional force of the pick-up roller 5A. and a separator section 6 for separating these sheets and reliably feeding out one sheet to be preceded. 6A indicates a feed roller, and the friction coefficient is the same as that of the feed roller 6A.
Shows a smaller reverse roller.

On the other hand, the pick-up roller 5A can be installed in either a fixed type or a movable type, but recently the movable type is the majority in order to ensure stability of operation.

In this movable system, as shown in FIG. As a result, the sheet 1 is repeatedly and continuously rotated as shown in FIG. This is so effective that only the leading sheet 1 can be fed out from the paper loading table 2 at any time.

[Problem that the invention attempts to solve]

However, in such a conventional example, since the paper loading table 2 is constituted by a flat floor surface 10 and a flat sheet pressing back plate 4, etc., the reciprocating rotation of the pick-up roller section 5 with respect to the sheet 1, that is, the sheet Due to the vibration for sheet separation transmitted to the sheet 1 and the reaction force generated during sheet feeding, a part of the sheet 1 is shifted in the opposite direction to the sheet feeding direction X as shown in FIG. There is.

For this reason, in recent years, attempts have been made to provide a stopper 11 behind the stacked sheets 1 as shown in FIG. 11, thereby preventing the above-described positional displacement of the sheets 1. However, with such a stopper 11, when handling sheets 1 of different sizes, it takes time and effort to adjust the position of the stopper 11, and on the other hand, when handling sheets 1 of different sizes, has always had the essential drawback that the stopper 11 cannot be used at all.

The present invention improves the inconveniences of the conventional example and is capable of almost completely eliminating the inconvenience of each sheet shifting backward even when a plurality of sheets of different sizes are mixedly stacked. Its purpose is to provide a paper loading platform for a paper feeding device.

[Means for solving problems]

Therefore, in the present invention, a paper loading table of an automatic paper feeder is provided with a sheet pressing back plate on one side, and the other side is installed close to a sheet feeding section, and is configured to stack predetermined sheets upright on the floor. In order to achieve the above object, a plurality of low steps for locking the seat or equivalent locking means are provided in a stepped manner on the floor surface on the rear end side of the seat. It is something to do.

[First Embodiment of the Invention] The first embodiment of the invention will be described below with reference to Figures 1 to 3.
This will be explained based on the diagram.

In FIGS. 1 to 3, reference numeral 20 indicates a paper loading table on which sheets 1 such as checks are stacked upright, and 21 indicates a sheet pressing back plate provided at one end of the paper loading table 20. shows. In this embodiment, the sheet pressing back plate 21 is configured to be biased by a pressing mechanism (not shown) to constantly press the entire stacked sheet 1 in the direction of arrow Y. In this case, in this embodiment, the floor surface 22 is fixed on the main body of the automatic paper feeder and the sheet pressing back plate 21 is movable, but if necessary, the sheet pressing back plate 21 may be moved. The board 21 is fixed to the floor surface 22, and the entire sheet 1 is moved along with the floor surface 22 in the direction indicated by the arrow Y in the figure.
A configuration may also be adopted in which the paper is transferred to a paper feeding mechanism located at the other end of the direction.

As shown in FIGS. 1 and 2, the floor surface 22 has a plurality of steps for locking the sheet on the rear end side of the sheet 1, that is, on the opposite side to the conveyance direction X of the sheet 1. shaped stepped portions 23, 23,
...is formed. Each step 23 has a second
They are formed at positions l ₁ , l ₂ , . . . that are slightly larger than the length dimension of the sheets 1 of different sizes, such as the sheets 1A and 1B shown in the figure.
24 indicates a contact reference plate. Note that this contact reference plate 24 is fixed on the main body of the above-mentioned automatic paper feeder in the case where the floor surface 22 is movable.

In addition, each step portion 23 formed on the floor surface 22
, the horizontal angle of the rising surface 23A has a spread angle of α degrees with respect to the direction of lateral movement (Y direction) of the sheet 1 (see FIGS. 1 and 3).
(see figure). Therefore, the sheet 1 can be smoothly moved in the Y direction. The other configurations are the same as those of the conventional example described above.

In this way, in the above embodiment, the floor surface 22
When the seat 1 tries to move backward due to vibration or other reasons, the rear end of the seat 1 moves to the nearest step 23.
The sheet hits the edge of the sheet 1, preventing further backward movement, preventing a large displacement of each sheet 1, and at the same time,
The conventionally required stopper (1 in Figure 11)
1) is no longer necessary, and as a result, the automatic sheet feeder using this embodiment has the advantage of being able to extremely smoothly stack and pull out each sheet.

Furthermore, when the entire sheet moves laterally in the Y direction due to the action of the sheet pressing back plate 21 described above, the widening of the angle α of each stepped portion 23 causes the lateral movement of the sheet to be caused by the sheet pressing back plate 21. The operation is carried out smoothly by slight pressure of the plate 21, and in this respect, damage to each sheet can be prevented in advance. The advantage is that the entire process can be carried out more smoothly with less driving force.

[Second Embodiment] Next, a second embodiment of the present invention will be described based on FIG. 4.

In this second embodiment, thin plates P ₁ , P ₂ , P ₃ , P ₄ , P ₅ having predetermined dimensions are shown in the same figure when forming the step portions 23, 23, . . . in the first embodiment described above. The other configurations are the same as those of the first embodiment described above.

Even in this case, in addition to having the same function and effect as the first embodiment described above, it is also possible to significantly reduce the cost since manufacturing is particularly easy. If the paper is set to be movable, it has the advantage of being able to handle sheets of various sizes.

[Third Embodiment] Next, a third embodiment will be described based on FIGS. 5 and 6.

In this embodiment, when forming the step portions 23, 23 in the first embodiment described above, the horizontal surface 2 of each step portion is
3B, 23B, . . . are set at a constant slope. That is, while the horizontal surfaces 23B, 23B, . . . of each step in the first embodiment described above are all parallel surfaces, in the third embodiment, The angle of inclination of the horizontal surface 23B is set to increase successively as β ₁ , β ₂ , and β ₃ as the frame increases. The other configurations are the same as those of the first embodiment described above.

Even in this case, in addition to having the same effect as the first embodiment described above, as shown in FIG.
Since the sheets 23A, . . . can be uniformly received and supported, there is an advantage that damage to each sheet 1 can be prevented.

[Fourth Example] Next, a fourth example will be described based on FIGS. 7 and 8.

This embodiment uses a sheet using relatively thick wire rods 33, 33, . . . as shown in the figure so as to function exactly the same as the stepped portions 23, 23, . . . in the first embodiment. A plurality of them (three in this embodiment) are provided at appropriate intervals depending on the size. α indicates the spread angle of each wire 33, h ₁ , h ₂ , h ₃ indicates the installation height of each wire,
Further, 40 indicates a cutout portion for feeding out the sheet. The other configurations are the same as those of the first embodiment described above.

In addition to having the same effect as the first embodiment described above, this arrangement also has the advantage that air can easily enter between the sheets from below, and that the sheets can be separated and fed out smoothly. It also has the advantage of being easy to handle due to its simplified structure and reduced weight.

[Effect of idea]

As described above, according to the present invention, an automatic sheet feeding device is provided with a sheet pressing back plate on one side, and the other side is installed close to a sheet feeding section, and has a structure in which predetermined sheets are stacked upright on the floor. In the paper loading table, a plurality of low step portions or equivalent locking means for sheet locking are provided in a step-like manner on the floor surface on the rear end side of the sheet, so that vibrations and other causes may occur. When the sheet attempts to move in the opposite direction to the feeding direction, that is, backward, the rear end of each sheet comes into contact with the nearest step or the edge of the corresponding locking means. Therefore, further backward movement can be prevented, and the locking means also acts on a plurality of sheets having different lengths to reliably prevent the backward movement of each sheet. As a result, even if sheets of different sizes are stacked together, the leading edge of the sheet feeding mechanism can always be aligned and the entire sheet can be transferred to the paper feeding mechanism side without causing any problems, an unprecedented practicality. Therefore, it is possible to provide a paper loading table for an automatic paper feeder that is highly valuable.
