Description

  The present invention relates to a technology of a paper cassette apparatus.

Conventionally, printers provided in copiers, copiers, and the like have been provided with a paper feed cassette as a recording paper supply source. This paper feed cassette changes the size of the recording paper to be accommodated by adjustment. It is possible.
In such a paper feed cassette, the maximum size of recording paper that can be accommodated in the paper cassette and fed toward the printer main body is, for example, the standard A3 size. If the paper feed cassette is compatible with the standard A3 size, it is also compatible with smaller standard A4 size and standard B5 size recording sheets.

In such a paper feed cassette, a bottom plate (flapper) on which recording paper is placed is provided so as to be rotatable (swingable), and a positioning guide for positioning the recording paper according to the paper size is provided. ing.
The recording paper on the bottom plate is desirably placed on the bottom plate at an inclination angle as gentle as possible from the viewpoint of preventing positional displacement with respect to the bottom plate. Therefore, the size of the bottom plate is set to a size that allows the entire recording paper of the maximum size (for example, standard A3 size) that can be handled by the paper feed cassette to be placed.
A positioning guide is provided in the casing in order to fix the position of recording paper of different sizes on the bottom plate. A plurality of guides are provided to enable positioning of the recording paper on the bottom plate in both the longitudinal direction and the short direction of the bottom plate (casing). The inner wall of the casing is also used for positioning the recording paper on the bottom plate.
A longitudinal positioning guide is provided in the casing so as to be movable and lockable in the longitudinal direction to accommodate different paper sizes, and a lateral positioning guide in the lateral direction to accommodate different paper sizes. The casing is movably and lockable.
Then, the same sheet feeding cassette is used as a sheet feeding cassette for the standard A3 size by appropriately moving the positioning guide in the longitudinal direction and the positioning guide in the short direction according to the size of the recording paper to be used. However, it is also possible to use a standard A4 size paper feed. It is also possible to change the orientation of the longitudinal direction of the recording paper with respect to the feeding direction of the recording paper, as in A4 portrait and A4 landscape.

In addition, since the weight of the recording paper laminated body placed on the bottom plate changes depending on the size of the recording paper to be accommodated, the magnitude of the urging force that presses the bottom plate toward the separating and feeding means correspondingly. Need to be adjusted.
This is because separation pressure of the recording paper by the separation feeding means is maintained by keeping the contact pressure of the recording paper to the rollers constituting the separation feeding means as constant as possible regardless of the total weight of the recording paper laminate. This is to ensure that it is properly performed.
This adjustment is performed by, for example, a service person and is not easily performed by the user himself / herself.

As a technique related to such a paper feed cassette, there is a technique disclosed in Patent Document 1. This technique prevents a problem that the space inside the casing is wasted in the paper feed cassette.
For example, when recording paper of a standard A4 size or smaller is loaded and used in a paper feed cassette capable of stacking recording paper up to a standard A3 size, more than half of the space inside the casing is wasted. The technique disclosed in No. 1 prevents such a problem.
JP 2003-267565 A

In a paper feed cassette that can use a relatively large size recording paper such as a standard A3 size, when a recording paper having a size smaller than a prescribed maximum size is accommodated, the space inside the casing is viewed from the user's viewpoint. May be wasted.
Although the technique disclosed in Patent Document 1 improves this problem, the apparatus configuration is complicated, and there is a problem that causes an increase in the manufacturing cost of the paper feed cassette.

For example, when a standard A4 size recording paper is accommodated in a paper feed cassette having the maximum standard A3 size, the size of the empty space generated in the casing is a size capable of accommodating the standard A4 size recording paper.
For this reason, the user may put a spare sheet in an attempt to use the empty space in the casing. Here, in order to properly separate and feed the recording paper by the separating and feeding means, the urging force for urging the bottom plate is set according to the recording paper size, but when the spare paper is put in the casing, A weight larger than the planned weight is applied to the bottom plate.
In the paper feeding cassette in a state where the standard A4 size recording paper is fed, when the spare paper is put in the empty space, the standard A3 size recording paper is substantially placed on the bottom plate. Here, the urging force for pressing the bottom plate upward (separate feeding means side) is in a state where the urging force is set so as to correspond to the standard A4 size. In this case, the urging force for lifting the bottom plate is insufficient, leading to problems such as paper feed failure, skewing, and paper jam.

  That is, the problem to be solved is to prevent the user from inserting a spare sheet into an empty space in the casing in a sheet feeding cassette apparatus that can supply different recording sheet sizes depending on settings.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

That is, in claim 1,

  As effects of the present invention, the following effects can be obtained.

  According to the first aspect of the present invention, the user cannot store spare recording paper in the empty space. The urging force applied to the bottom plate is set according to the recording paper size. However, by preventing the storage of the spare recording paper, the weight exceeding the corresponding range of the urging force may be applied to the bottom plate. Absent.

  In the second aspect, in addition to the effect of the first aspect, the baffle member is configured at low cost.

  According to the third aspect, in addition to the effect of the first or second aspect, the storage of the spare recording paper in the empty space by the user is effectively prevented while the apparatus configuration is inexpensive.

A sheet cassette apparatus 1 according to an embodiment of the present invention will be described with reference to the drawings.
The paper feed cassette device is a device that feeds recording paper to a printer (image forming apparatus), and is used by being attached to the printer. The paper feed cassette apparatus 1 according to the present embodiment is a separate unit from the printer, and is configured as a unit that can be stacked in one or more stages below the printer.

As shown in FIGS. 1 and 2, the casing of the paper feed cassette apparatus 1 includes a drawer case 2 in which recording paper is accommodated and a receiving case 3 in which the drawer case 2 is accommodated in a freely drawable manner.
Based on the posture of the sheet feeding cassette device 1 in use, the drawer case 2 has a shape with its upper surface cut away from a hollow rectangular parallelepiped, and the receiving case 3 has one side cut away from a hollow rectangular parallelepiped. It has a shape. The drawer case 2 can be pulled out to one side with respect to the receiving case 3. The receiving case 3 is also formed with an opening for allowing the recording paper to pass in the vertical direction.
The drawer case 2 accommodates recording sheets stacked in the vertical direction. The drawer case 2 is accommodated in the receiving case 3 so as to be freely drawn out.

  In the drawer case 2, a bottom plate 4 on which the recording paper laminate 7 is placed, a feeding roller 5 and a separation roller 10 related to feeding of the recording paper, a spring 6 that presses the bottom plate 4 toward the feeding roller 5 side, and Side guides 8 and 8 and an end guide 9 for positioning the recording paper laminate 7 on the bottom plate 4 are provided.

The bottom plate 4 is rotatably provided on the drawer case 2 via a rotation support shaft 11. The rotation support shaft 11 is located at one end of the bottom plate 4, and the end portion (open side end 4 a) of the bottom plate 4 on the side opposite to the rotation support shaft 11 can move up and down.
The feeding roller 5 is positioned above the open end 4a, and the spring 6 is positioned below the open end 4a. The spring 6 is provided between the bottom plate 4 and the inner bottom surface of the drawer case 2, and the open end 4 a is urged toward the feeding roller 5 by the spring 6.

The feeding roller 5 is means for feeding the recording paper to the printer using friction caused by contact with the recording paper, and the separation roller 10 is the uppermost one when a plurality of recording papers are fed simultaneously by the feeding roller 5. It is means for reversely feeding the recording paper to the bottom plate 4 side excluding the sheet. The separation roller 10 is configured to rotate idly when a certain torque or more is applied. When both surfaces of one recording sheet are in contact with the feeding roller 5 and the separation roller 10 at the same time, the feeding roller The recording paper is fed out with priority given to the drive rotation No. 5.
As described above, the feeding roller 5 and the separation roller 10 constitute a recording paper separating and feeding unit.
The recording paper separating and feeding means is not particularly limited, and may have other configurations.

The recording paper laminate 7 on the bottom plate 4 is pressed against the feeding roller 5 by the urging force of the spring 6, and the feeding roller 5 contacts the uppermost sheet of the recording paper laminate 7.
The feeding roller 5 is provided so that the axial direction of the feeding roller 5 is parallel to the rotation support shaft 11, and the recording paper is fed from the recording paper laminate 7 on the bottom plate 4 by the feeding roller 5. It is drawn out from the rotation support shaft 11 toward the open end 4a. The recording paper fed by the feed roller 5 is fed upward on the side of the feed roller 5 by a guide provided in the casing of the paper feed cassette device 1.

In this embodiment, the recording paper laminate 7 on the bottom plate 4 is “center aligned” in the left-right direction with respect to the feeding direction.
Specifically, the recording paper laminate 7 is positioned so that the center of the bottom plate 4 and the center of the recording paper coincide with each other by the pair of side guides 8 and 8 that are restricted in movement on both sides in the left-right direction. . Each side guide 8 is provided in the drawer case 2 so as to be movable and lockable in the left-right direction with respect to the feeding direction. The bottom plate 4 is formed with the left and right elongated holes corresponding to the side guides 8 so that the bottom plate 4 and the side guides do not interfere with each other regardless of the position of the side guides 8.
Further, the feeding roller 5 and the separation roller 10 are also provided at the center position of the bottom plate 4 in the left-right direction, and the feeding roller 5 contacts the center of the recording paper regardless of the recording paper size.
The feeding direction is a direction in which the recording paper is fed from the rotation support shaft 11 to the feeding roller 5.

Further, in the feeding direction, the recording paper laminate 7 on the bottom plate 4 is configured to be “end aligned” to the feeding roller 5 side.
Specifically, the recording paper laminate 7 is restricted in movement on both sides in the feeding direction by the inner wall (tip side inner wall 2 a) of the drawer case 2 on the side of the feeding roller 5 and the end guide 9. It is positioned so that the end of the recording paper laminate 7 is positioned below.
The end guide 9 is provided in the drawer case 2 so as to be movable and lockable in the feeding direction. The bottom plate 4 is formed with a long hole in the feeding direction corresponding to the end guide 9 so that the bottom plate 4 and the end guide 9 do not interfere regardless of the position of the end guide 9.

Further, the bottom plate 4 is formed to have a size that allows the maximum size recording paper that can be accommodated in the drawer case 2 to be placed on the entire surface.
In the paper feed cassette apparatus 1 according to the present embodiment, the maximum recordable paper size that can be accommodated is the standard A3 size. Correspondingly, the standard A3 size recording paper is placed on the entire surface of the bottom plate 4. It is possible to mount it.
Here, “place all over” means that not only a part of the recording paper but also the whole is placed on the bottom plate 4.
With this configuration, the change in the inclination angle of the bottom plate 4 due to the change in the thickness of the recording paper on the bottom plate 4 is reduced as much as possible within the usable space of the drawer case 2. Then, the positional deviation due to the inclination of the recording paper due to the change in the thickness of the recording paper and the fluctuation of the contact position between the feeding roller 5 or the separation roller 10 and the recording paper are minimized so that no trouble occurs in the feeding. Yes.

The paper feeding cassette device 1 is configured to be able to switch the urging force that presses the bottom plate 4 toward the feeding roller 5 side.
This is because the urging force applied to the bottom plate 4 is changed according to the weight of the recording paper laminate 7 placed on the bottom plate 4 so that the contact between the feeding roller 5 and the recording paper is different in the recording paper size. In other words, the recording paper laminate 7 is always kept at an appropriate level regardless of the weight.
For example, the standard A3 size recording paper is twice as large as the standard A4 size recording paper, so that when the recording paper is fully loaded on the bottom plate 4, the weight applied to the bottom plate 4 is doubled. If the recording paper is fed to the printer side and the thickness of the recording paper stack is reduced, the weight of the recording paper stack is also reduced. However, on average, as the recording paper size increases, the bottom plate The weight of the recording paper applied to 4 also increases.
Therefore, as the recording paper size increases, the force for urging the bottom plate 4 upward is increased so that the contact between the feeding roller 5 and the recording paper is properly maintained, and the recording paper size is reduced. Accordingly, the biasing force is reduced so that the force biasing the bottom plate 4 upward does not become excessive.

The spring 6 is an urging unit that presses the bottom plate 4 toward the feeding roller 5, but the upward urging force applied to the bottom plate 4 can be changed by replacing the spring 6 with a spring having a different elastic coefficient.
Alternatively, the upward biasing force applied to the bottom plate 4 can also be changed by making the arrangement position of the spring 6 adjustable in the feeding direction. That is, the position of the spring 6 that is the power point is moved closer to or away from the rotation support shaft 11 that is the fulcrum of the bottom plate 4.
Such replacement and position adjustment of the spring is performed by, for example, disassembling a part of the casing of the sheet feeding cassette device 1 by a service person or the like.
Note that the method of switching the urging force for pressing the bottom plate 4 toward the feeding roller 5 is not limited to the above method, and may be another method.

Next, the baffle members arranged in the empty space on the bottom plate 4 will be described.
In the drawer case 2 that can accommodate the standard A3 size recording paper, when the standard A4 size recording paper is accommodated, that is, when the paper cassette apparatus 1 is used as a supply source of the standard A4 size recording paper. In the drawer case 2, an empty space capable of accommodating a standard A4 size recording paper is generated.
Here, since it is possible to place the standard A3 size recording paper on the entire surface of the bottom plate 4, when the standard A4 size recording paper is accommodated in the drawer case 2 as a spare, this preliminary recording paper is used. Is also placed on the bottom plate 4.
Then, even if the paper feed cassette apparatus 1 is set for supplying the standard A4 size recording paper by switching the urging force of the bottom plate 4 described above, the bottom plate 4 corresponds to the standard A3 size recording paper. As a result, the weight is increased, and there is a possibility that a problem may occur in the feeding of the recording paper from the paper feed cassette device 1.
Therefore, a baffle member that is always located in the empty space on the bottom plate 4 is provided in the paper feed cassette device 1 as a means for preventing the preliminary recording paper from being stored in the empty space.

As shown in FIGS. 1 and 2, in the drawer case 2, a rod-like member 12 that connects the end guide 9 and the inner wall (rear end side inner wall 2 b) of the drawer case 2 on the side opposite to the feeding roller 5 is provided. It is provided as the baffle member.
This rod-shaped member 12 is provided at an upper position of the bottom plate 4.
Further, the rod-like member 12 has one end portion rotatably provided on a rib 9a erected on the end guide 9 via a rotation support shaft 13, and the other end portion erected on the rear end side inner wall 2b. The rib 2c is rotatably provided via a rotation support shaft 14. In addition, a long hole 12a is formed in the rod-shaped member 12 along the longitudinal direction, and the rotation support shaft 13 that connects the rod-shaped member 12 and the end guide 9 is movable in the long hole 12a. It has become.
For this reason, when the end guide 9 is moved along the feeding direction, the rod-shaped member 12 is inclined in conjunction with the movement of the end guide 9. By this inclination, the length (projection length) of the rod-shaped member 12 in the moving direction of the end guide 9 (the feeding direction) expands and contracts.

FIG. 3 shows the inside of the drawer case 2 in a state where the standard A3 size recording paper is accommodated, and the end guide 9 is located at the rear end portion of the bottom plate 4 in the feeding direction, and is at the maximum rear end side. The state is close to the inner wall 2b. At this time, the rotation support shaft 13 is also moved in the longitudinal direction of the rod-shaped member 12 along the long hole 12a, and is in a state of being closest to the rotation support shaft 14 side.
In this way, the rod-shaped member 12 (projected length thereof) expands and contracts in the moving direction of the end guide 9 (the feeding direction). When there is an empty space in the drawer case 2, the bar-like member is always positioned above the bottom plate 4 in the empty space, and the bottom plate 4 is covered. Can no longer be accommodated.

The sheet feeding cassette device 1 including the baffle members having the above configuration will be summarized.
The paper feeding cassette device 1 is a device for feeding recording paper to a printer, and includes a bottom plate 4, a feeding roller 5 and a separation roller 10, a spring 6, side guides 8 and 8, and an end guide 9.
Here, the casing of the sheet feeding cassette apparatus 1 includes a drawer case 2 and a receiving case 3 in which the drawer case 2 is housed so as to be freely pulled out.
The bottom plate 4 has a recording paper laminate 7 (including a single sheet) placed thereon and is supported by the drawer case 2 (the casing) so as to be rotatable up and down.
The feeding roller 5 and the separating roller 10 are separating and feeding means, and come into contact with the recording paper laminate 7 on the bottom plate 4 to separate and feed one of them.
The spring 6 is a biasing unit that presses the bottom plate 4 toward the separation feeding unit (feeding roller 5).
The side guides 8 and 8 and the end guide 9 are positioning guides that are supported by the drawer case 2 (the casing) so as to be movable and lockable, and position the recording paper laminate 7 on the bottom plate 4.

In particular, the bottom plate 4 has such a size that the recording paper of the maximum size that can be accommodated in the drawer case 2 can be placed on the entire surface.
The urging means is configured such that the urging force can be switched according to the recording paper size. As described above, this switching of the urging force is performed by replacing the spring 6 with a spring having a different elastic coefficient or by changing the arrangement position of the spring (including the spring 6) in the feeding direction.
Further, a baffle member for connecting the positioning guide and the inner wall of the casing on the anti-separation feeding means side is provided. In the present embodiment, the baffle member as the rod-shaped member 12 is configured between the end guide 9 and the rear end side inner wall 2b. However, the side guide 8 and the drawer case 2 on the side opposite to the separating means are not provided. It may be further provided between the inner wall.
And the said baffle member is located above the said baseplate 4, and is comprised so that it may expand and contract in response to the movement of this positioning guide in the movement direction of the said positioning guide. In the present embodiment, the bar-like member 12 that is a baffle member changes its inclination angle by interlocking with the end guide 9, and its projection length in the feeding direction expands and contracts.

For this reason, in the casing (drawer case 2), the baffle member is always located inside the empty space located outside the positioning guide (on the side opposite to the separating / feeding means), and above the bottom plate 4 positioned in the empty space. A part or all of the above is covered with a baffle member.
Therefore, the user cannot store spare recording paper in the empty space. The urging force applied to the bottom plate 4 is set according to the size of the recording paper. By preventing the storage of the spare recording paper, a weight exceeding the corresponding range of the urging force is applied to the bottom plate 4. There is nothing.

In the present embodiment, the baffle member is the rod-shaped member 12, but is not limited to this configuration.
A baffle member that connects the positioning guide and the inner wall of the casing on the side opposite to the feeding means is positioned above the bottom plate 4 and extends and contracts in conjunction with the movement of the positioning guide in the moving direction of the positioning guide. Other configurations are possible as long as they are configured.
For example, an accordion-like or pantograph-like member that can be expanded and contracted is provided between the end guide 9 and the rear-end-side inner wall 2 b, and these members may expand and contract in conjunction with the movement of the end guide 9. .

In particular, the baffle member is a rod-shaped member 12 that is rotatably provided on the positioning guide and the inner wall of the casing on the anti-separation feeding means side, and the rod-shaped member 12 and the positioning guide or the inner wall of the casing are connected to each other. The connecting portion is supported movably with respect to the rod-shaped member.
In particular, in the present embodiment, a rod-shaped member 12 is rotatably provided on the end guide 9 and the rear end side inner wall 2b, and along a long hole 12a formed in the rod-shaped member 12 along the longitudinal direction thereof. The rotation support shaft 13 as a connecting portion that rotatably connects the end guide 9 and the rod-shaped member 12 is supported movably.

  Therefore, the baffle member is configured at a low cost.

When the baffle member is a rod-like member, and the rod-like member is rotatably provided on the positioning guide and the inner wall of the casing on the side opposite to the separation feeding means, the rod-like member is interlocked with the movement of the positioning guide. The structure for inclining the member is not limited to the structure described above (a structure in which the connecting portion is movably supported with respect to the rod-shaped member).
For example, the rod-shaped member 12 is rotatably provided on the end guide 9 and the rear end side inner wall 2b, and the rotation support shaft 14 serving as a connecting portion between the rod member 12 and the rear end side inner wall 2b is connected to the rear end side inner wall 2b. It is good also as a structure supported movably with respect to.
That is, in the configuration in which the baffle member is a rod-shaped member, and the rod-shaped member is rotatably provided on the positioning guide and the inner wall of the casing on the anti-separation feeding means side, the connecting portion between the rod-shaped member and the inner wall of the casing is provided. Even if it is the structure made movable with respect to a casing inner wall, the structure by which the connection part of a rod-shaped member and a positioning guide can be made movable with respect to a positioning guide may be sufficient.

In particular, the positioning guide to which the baffle member is connected is a positioning guide provided to be movable in the longitudinal direction in the casing.
In the present embodiment, the longitudinal direction of the drawer case 2 coincides with the feeding direction of the recording paper, and the positioning guide provided movably in the feeding direction is the end guide 9. The inner wall of the drawer case 2 on the side opposite to the end guide 9 on the side opposite to the separating / feeding means (feeding roller 5) is the rear end side inner wall 2b.
In the present embodiment, the baffle member is provided only in the end guide 9 among the three positioning guides provided in the drawer case 2.

For this reason, a baffle member is arrange | positioned in the site | part in which the largest empty space arises among the empty spaces produced in a casing.
Therefore, it is possible to effectively prevent the user from storing the spare recording paper in the empty space while reducing the apparatus configuration.
