DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to printing paper and OHP
(Over-Head Projector) The present invention relates to a sheet feeding apparatus for sequentially feeding a sheet body such as a sheet to a copying machine or the like.

[0002]

2. Description of the Related Art Some commercial copiers and the like are equipped with a large-capacity sheet feeding device as a sheet feeding device in order to consume a large amount of sheets such as printing paper. As such a sheet feeding device, there is a device in which a first sheet storing portion and a second sheet storing portion are arranged in series in a sheet feeding direction, for example, Japanese Patent Application Laid-Open No. H6-144600. It is described in.

[0003] Such a sheet feeding apparatus is called a tandem tray system or the like, and usually separates and feeds the sheet bodies stored in a first sheet storing section one by one by a separating and feeding mechanism. The presence or absence of a sheet member in the first sheet storage portion is constantly monitored by a sheet detection sensor, and when the end of the sheet member is detected, the batch replenishment mechanism transfers the second sheet storage portion to the first sheet storage portion. Replenish many sheets at once.

Therefore, the above-described sheet feeding apparatus can continuously feed an extremely large amount of sheets, and can reduce the frequency of work of a user who replenishes the sheets by half. Further, it is not necessary to increase the overall height to achieve this, and the dead space can be effectively used.

That is, in a general copying machine or the like, a structure for selectively feeding sheets of various sizes is adopted, and a plurality of sheet storage units are provided vertically below the apparatus main body. I have. For example, in a sheet storage unit that stores B4 size paper vertically and a sheet storage unit that stores B5 size paper horizontally, the length of the B5 size sheet storage unit is approximately half that of B4 size. If they are simply arranged vertically, a dead space occurs behind the B5 sheet storage unit. Therefore, if such a sheet feeding apparatus is formed as the tandem tray system described above, the capacity of the sheet body that can be fed using the dead space can be doubled.

[0006]

In the above-described sheet feeding apparatus, the sheet body is usually separated and fed from the first sheet storage section, and when the sheet body is completed, the second sheet storage section transfers the sheet body from the second sheet storage section. One sheet storage unit can be replenished with sheet bodies.

However, in such a sheet feeding apparatus,
In order to replenish a large amount of sheets at once from the second sheet storage unit to the first sheet storage unit, these sheet storage units communicate with each other. For this reason, when the sheet body is separated and fed from the first sheet storage section, the sheet body stored in the second sheet storage section collapses toward the first sheet storage section, causing a jam. May be.

In particular, since the bottom plate of the first sheet storage section is provided so as to be movable vertically in order to separate and feed a large amount of sheets, the bottom plate of the first sheet storage section is raised. If the sheet body of the second sheet storage unit collapses in this state, the bottom plate cannot be lowered and the drive motor may be damaged.

[0009]

According to the first aspect of the present invention,
A first sheet storage section and a second sheet storage section each storing a large number of sheet bodies are arranged in series, and the sheet bodies stored in the first sheet storage section are separated by a separate feeding mechanism into one sheet. The sheet is separately fed, and the presence or absence of the sheet body stored in the first sheet storage unit is detected by a sheet detection sensor. In a sheet feeding apparatus for replenishing a large number of sheets at a time in the first sheet storage section, a sheet supporting member for supporting a sheet body in a gap between the first sheet storage section and the second sheet storage section And a member moving device for movably supporting the sheet supporting member and retracting the sheet supporting member from the gap between the first sheet storing portion and the second sheet storing portion when replenishing the sheet member. Therefore,
While storing a large amount of sheet bodies in the second sheet storage section,
In a state where the sheet body is separated and fed from the first sheet storage section, the sheet support member is located in the gap between these sheet storage sections, so that the sheet body of the second sheet storage section is moved to the first sheet storage section. It does not crumble down. When replenishing a large amount of sheets at once from the second sheet storage unit to the first sheet storage unit, since the member moving device retracts the sheet support member from the gap between the first and second sheet storage units,
This sheet support member does not hinder the replenishment of the sheet body.

According to a second aspect of the present invention, in the first aspect of the invention, at least one of the first sheet accommodating portion and the second sheet accommodating portion is movably supported, and the sheet member is moved from both sides. A pair of side fences for holding are provided, and a position adjusting device for adjusting the position of the sheet support member in accordance with the position of the movable side fence is provided.
Therefore, in the first and second sheet storage units, at least one of the pair of side fences is movable, so that sheets of various widths can be stored. Thus, even if the width of the sheet body stored in the sheet storage unit changes due to the movement of the side fence, the position of the sheet support member is adjusted by the position adjustment device in accordance with the position of the side fence. The sheet body of the sheet storage section does not collapse toward the first sheet storage section.

According to a third aspect of the present invention, in the second aspect of the present invention, the position adjusting device adjusts the position of the seat supporting member by controlling the operation of the member moving device. Therefore, the position adjusting device simply adjusts the position of the sheet supporting member without requiring a dedicated mechanism.

According to a fourth aspect of the present invention, in the first, second or third aspect of the present invention, the first sheet storing portion and the second sheet storing portion are integrally supported to allow the inside and outside of the apparatus main body to be connected. The first sheet storage unit and the second sheet storage unit move the sheet support member from the inside to the outside of the apparatus main body to provide the storage unit support mechanism for moving the sheet support member to the first sheet storage unit. And a forcible moving device for retreating from a gap between the second sheet storing portion and the second sheet storing portion. Therefore, since the first and second sheet storage units move integrally from the inside of the apparatus main body to the outside, it is possible to easily replenish the first and second sheet storage units with sheets. In the process in which the first and second sheet storage units move from the inside of the apparatus main body to the outside, the forcible moving device retracts the sheet support member from the gap between the first and second sheet storage units. Does not hinder the work of replenishing the sheet body.

[0013] According to the fifth aspect of the present invention, the first, second, and third aspects are provided.
The invention according to claim 3 or 4, further comprising a storage unit support mechanism for integrally supporting the first sheet storage unit and the second sheet storage unit and moving the first sheet storage unit and the second sheet storage unit to the inside and the outside of the apparatus main body. Forced return of the sheet support member to the gap between the first sheet storage section and the second sheet storage section while the storage section and the second sheet storage section move from the outside to the inside of the apparatus main body. A moving device was provided. Therefore, since the first and second sheet storage units move integrally from the inside of the apparatus main body to the outside, it is possible to easily replenish the first and second sheet storage units with sheets. In the process where the first and second sheet storage units move from the outside of the apparatus body to the inside,
The forcible moving device returns the sheet support member to the gap between the first and second sheet storage units. For this reason, even if the sheet support member is retracted from the gap between the first and second sheet storage sections in a state where the first and second sheet storage sections are drawn out of the apparatus main body, the first and second sheet storage sections are not moved. When the sheet storage section is moved into the apparatus main body, the sheet supporting member returns to the gap between the first and second sheet storage sections, and the sheet body of the second sheet storage section is moved to the first sheet storage section. It does not collapse toward the part.

According to a sixth aspect of the present invention, in accordance with the fifth aspect of the present invention, even if the first sheet storage portion and the second sheet storage portion move to the inside of the apparatus main body, the sheet support member is provided with the first sheet storage member. An error notification device is provided for notifying an error unless the gap is returned to the gap between the sheet storage unit and the second sheet storage unit. Accordingly, when the first and second sheet storage sections drawn out of the apparatus main body are replenished with sheets, and the first and second sheet storage sections are moved inside the apparatus main body, the first and second sheet storage sections are moved. The sheet support member returns to the gap between the sheet storage portions. However, if the positions of the sheets replenished in the first and second sheet storage units are not proper, the sheet support member collides with the sheets and does not return to the gap between the first and second sheet storage units. In such a state, an error is notified by the error notifying device, so that the user is notified that the position of the replenished sheet body is not appropriate.

Further, since the position adjustment of the moving fence 26 is performed by operation control of the member moving device 32, a dedicated mechanism is not required, and the position of the moving fence 26 is easily adjusted.

Further, as described above, the tray box 9 is pulled out from the apparatus main body 11, and the first and second paper feed trays 7,
7, when the printing paper 5 is replenished, the movable fence 26 cannot return to the gap between the first and second paper feeding trays 7 and 8 unless the printing paper 5 is properly arranged, as shown in FIG.
However, if this return is not confirmed by the member position sensor 31, an error is notified to the user by the error notifying device, so that the user can quickly recognize that the position of the printing paper 5 is not appropriate and execute the processing. it can.

The present invention is not limited to the above-described embodiment, but allows various modifications. For example, here, the side fences 17 and 2 of the first and second sheet trays 7 and 8 are used.
Although the example has been described in which the printing paper 5 of various widths can be stored by making the printing paper 4 freely movable, a paper feeding device (not shown) in which the side fences 17 and 24 do not move and the size of the printing paper 5 cannot be changed is also possible. In this case, since the position of the moving fence 26 in the gap between the first and second paper feed trays 7 and 8 does not change, the first and second paper feed trays 7 and 8 are moved from the outside of the apparatus main body 11 to the inside. At the time of moving, the moving fence 26 can be returned to the gap between the first and second paper feed trays 7 and 8 by the forced moving device 35.

Also, here, the forcible moving device 35 moves the moving fence 26 in conjunction with the movement of the tray box 9 without requiring power by the contact between the leaf spring 34 of the apparatus main body 11 and the projection 33 of the rack 27. Although the movement of the moving fence 26 has been described as an example, the movement of the moving fence 26 can be realized by the operation of the member moving device 32 by driving the stepping motor 29.

Further, in this example, the position adjusting device controls the operation of the member moving device 32 in order to dispose the moving fence 26 at a position corresponding to the side fence 24. It is also possible to provide it independently of the moving device 32. For example, if a member moving device (not shown) for moving the pair of moving fences 26 is formed independently on the left and right and these member moving devices are individually connected to the side fence 24, the moving can be performed without complicated control. The fence 26 can be arranged corresponding to the side fence 24.
