Description

[Detailed description of the invention] The present invention relates to a universal paper feed cassette case that is used by being attached to the paper feed section of a copying machine. It is divided into a front cassette body and a rear cassette body, and a positioning means is provided for integrating both cassette bodies at a position corresponding to the longitudinal length of the copy sheets to be stored, and the front cassette body The present invention relates to an improved technique for a universal paper feed cassette case that is provided with a side edge regulating device whose position can be changed according to the width of the copy paper to be copied.

In the above-mentioned universal paper feed cassette case, the case body can be adjusted to a size according to the size of the copy paper to be fed, and therefore, one cassette case can accommodate a plurality of copy paper sizes.

Furthermore, compared to, for example, a universal paper feed cassette case that accommodates the copy paper size by changing the position of only the rear and side edge regulating devices for the copy paper, with this configuration, the overall size of the case remains unchanged. According to the cassette case configured as described above, the smaller the size of copy paper to be fed, the smaller the cassette case becomes, and the handling of the cassette case becomes easier.

Furthermore, if the copying machine is of the type with a moving optical system and the size of the copy paper to be fed is small, the cassette case can be made smaller, reducing the space occupied by the entire copying machine. It was developed because it has advantages such as being able to be made small.

However, in conventional universal paper feed cassette cases, it has been difficult to determine the size of the copy paper contained therein.

Alternatively, when changing the size of the cassette case depending on the size of copy paper to be stored, it is necessary to prepare the copy paper to be stored and adjust the size of the case body to match it. However, it requires a cumbersome operation.

The present invention was devised in view of the above circumstances, and includes the universal paper feed cassette case described at the beginning, in which the case body can be adjusted to a size according to the copy paper size. A feature is that a copy paper size display section for displaying the size of the stored copy paper is provided in the overlapping part of the paper.

Hereinafter, an embodiment of the present invention will be described based on the drawings. FIG. 1 shows the entire universal paper feed cassette case with a part cut away, and FIG. 2 shows a plan view thereof.

In the figure, reference numeral 1 denotes a case body which is divided in two in the paper feed direction F into a front cassette body 2 on the downstream side in the paper feed direction and a rear cassette body 3 on the upstream side in the paper feed direction.

Convex guide bodies 4, 4 are protruded from the lower portions of the outer surfaces of the left and right side walls 2a, 2a on the upstream side in the paper feeding direction of the front cassette body 2, and the left and right side walls 3a of the rear cassette body 3 are provided with convex guide bodies 4, 4. Concave guide grooves 5, 5 into which the guide bodies 4, 4 are fitted are provided at the lower part of the inner surface over the entire length in the paper feeding direction.

Therefore, the guide body 4 to the guide grooves 5, 5,
4, the front cassette body 2 and the rear cassette body 3 are made slidable relative to each other in the paper feeding direction F.

Next, reference numeral 6 denotes a mounting plate for placing copy sheets in a stacked manner, which includes the left and right side walls 2a of the front cassette body 2,
2a, it is mounted on the upstream side in the paper feeding direction and is vertically swingable around horizontal axes 7, 7 perpendicular to the paper feeding direction F, and is mounted by a biasing mechanism such as a coil spring (not shown). The free end side is biased upward.

Reference numerals 8 and 8 denote side edge regulating devices for regulating the left and right edges of the copy paper, which are disposed at the left and right cutouts 6a, 6a of the mounting plate 6, and are fitted to the pinion 10 and the racks 9, 9 that engage with the pinion 10. Therefore, the side end regulation position can be changed and set.

Reference numerals 11 and 11 denote copy paper separating claws, which are pivotally connected to the side edge regulating device 8 via a connecting member 12.

Next, reference numerals 13 and 13 are positioning means for integrating the two cassette bodies 2 and 3, which are slidable relative to each other in the paper feeding direction F. The front cassette body 2 is provided with an engaging body 15 which is formed in each of the guide grooves 5, 5 of the cassette body 3 and elastically engages with the trough of the rack 14.

Specifically, as shown in FIG. 3, the engaging body 15 is formed by bending a spring plate into a two-stage mountain shape, and forming the top part of the spring plate into an engaging part 15a for the valley part of the rack 14. Both side portions of the joining portion 15a are bent in two steps into leg portions 15b, 15b.

On the other hand, the guide bodies 4, 4 of the front cassette body 2
Nearby, deep and wide recesses 16, 16 that are open on the side and lower surfaces are formed, and the engaging portion 15a of the engaging body 15 is projected outwardly from the side opening 16a of the recess 16 beyond the guide body 4. In a state where
The legs 15b, 15b of the engaging body 15 are elastically deformed and press-fitted into the narrow inner parts 16b, 16b of the recess 16.

Thus, while the engaging body 15 can be easily set, it is possible to prevent the engaging body 15 from escaping from the recess 16.

The relative positions of the two cassette bodies 2 and 3 can be changed by a small pitch of the rack 14, so that even if the sizes of copy sheets to be accommodated are slightly different, they can be adjusted accordingly. The front and rear lengths of both cassette bodies 2 and 3 can be changed and set as desired.
Similarly, the position of restriction by the side edge restrictor can also be changed or set as desired depending on the copy paper size.

That is, the size of the cassette case can be changed and set to correspond to any size of copy paper.

Next, reference numeral 17 denotes a copy paper size display section for displaying the size of the stored copy paper.
It is provided at the polymerization part of

Specifically, on the outer surface of one (or both) side walls 2a of the front cassette body 2 and where the side walls 3a of the rear cassette body 3 always overlap, for example, the A and B rows of the JIS standard are installed. Attach a nameplate a that indicates the size of the copy paper, and on the other hand, attach it to the rear cassette body 3.
A through hole b is provided in the side wall 3a of the cassette body 3 so that when the relative positions of the cassette bodies 2 and 3 are changed to match a certain size of copy paper, a nameplate a corresponding to the size of the copy paper can be seen through. .

Therefore, it is possible to easily determine the size of the currently stored copy paper, or to change the relative position of both cassette bodies 2 and 3 when changing the copy paper to a different size copy paper. Settings can be easily performed.

FIG. 4 shows another embodiment of the copy paper size display section 17. This is the side wall 2a of the front cassette body 2.
An arrow mark c is provided on the top surface, and a name plate a indicating the copy paper size is provided on the top surface of the side wall 3a of the rear cassette body 3.

Incidentally, instead of displaying the size using the nameplate a, it is possible to make changes such as printing the size or, if the case is made of resin, configuring the size by bulging the resin material.

Further, as the positioning means 13, for example, a small pitch rack 14 is provided on the convex guide body 4 on the front cassette body 2 side, and an engaging body 15 that engages with the rack 14 is provided on the rear cassette body 3 side. can be changed.

As explained above, the universal paper feed cassette case of the present invention is different from the universal paper feed cassette case in which the case body can be adjusted to the size according to the copy paper size. Since it is equipped with a copy paper size display section to display the size of the copy paper stored, you can easily grasp the size of the copy paper stored, or
The operation of changing the size of the cassette case according to the size of the copy paper can be easily performed based on the size display section without having to prepare the copy paper to be accommodated and adjust it accordingly. Through simple improvements, it has become possible to improve the usability of the universal paper feed cassette case.
