Description

[Detailed Description of the Invention] The present invention relates to a copying material storage device for storing copying materials and the like.

More specifically, the present invention relates to a copy material storage device that can store and feed many types of copy materials of different sizes using one storage device.

Recently, in order to improve the efficiency of office work, storage devices have been used in which a regulating plate such as a side plate is movable so that a single storage device can feed several types of copy materials of different sizes.

However, in the above-mentioned conventional storage device, the separation claw moves while rubbing the surface of the stacked copy materials while the regulating plate is moved, which may disturb the stacking of the stacked copy materials.

Therefore, the present invention proposes a copy material storage box in which the movable side plates can be aligned without being hindered by the separating claws.

That is, in order to achieve the above object, the copy material storage box according to the present invention includes a regulation plate that is movable according to the dimensions of the copy materials for regulating the storage position of the copy materials, and a copy material storage box for loading the copy materials. a loading plate, a separation claw provided at the tip of the regulation plate in the feeding direction for separating and feeding the copy materials loaded on the copy material stacking plate, and a swingable support arm for supporting the separation claw; The apparatus is characterized in that it is comprised of a locking means for locking the regulation plate, and a swinging means for retracting the separation claw upward in conjunction with the release operation of the locking means.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view of a copy material storage box using an embodiment of the present invention, and FIG. 2 is a left sectional view thereof.

In the figure, 1 is a copy material storage box, and 2a and 2b are fixed side plates of the copy material storage box.

Further, 2c is a reference side plate, which is fixed to the storage box 1 with screws 13.

Further, 3at3b is a separation claw for separating copy materials one by one, and is attached to the reference side plate 2c and the movable side plate 10 so as to be able to swing around the shafts 4a and 4b so as to be located at the corner of the feeding side tip. It is being

Furthermore, the middle plate 5 on which copying materials are loaded extends over approximately half of the bottom of the main body of the storage box on the feeding side, and is connected to the fixed side plate 2a.

2b so as to be swingable about a shaft 6.

Note that a friction sheet 7 is provided at the tip of the intermediate plate 5 on the feeding side.

Also, both ends of the feeding side tip of the middle plate 5 are constantly pushed upward by push-up springs 8a and 8b installed in the storage box 1, and the middle plate 5 is pressed against the separating claws 3a and 3b. upward swing is regulated.

Incidentally, instead of the spring 8, when the storage box is loaded into the main body of a copying machine or the like, a configuration may be adopted in which at least the middle plate is pushed up during feeding by a push-up member provided on the main body.

Further, numeral 9 is a feeding roller that feeds the copy material from the storage box 1.

Here, the movable side plate 10 to which an embodiment of the present invention is applied is as follows:
It is provided in a space formed by cutting out a part of the middle plate 5, and moves in the direction of arrow A according to the width of the copying material.

This movable side plate 10 is a vertical plate 1 that regulates the side surface of the copy material.
0a, and a bottom portion 10b integrally provided at substantially right angles to the vertical portion 10a.

A guide rail 12 is fixed to the bottom surface 11 of the cassette and has the bottom plate 10b slidably interposed therebetween.

Therefore, the movable side plate 10 includes the guide rail 12 and its claw portion 10.
By the movement of the bottom plate 10b that is guided by the engagement of the bottom plate 10c, the bottom plate 10b moves along the guide rail 12 in accordance with the width size of the copying material.

The interlocking state of the locking mechanism of the movable side plate 10 and the separating claw 3b will be explained with reference to FIGS. 3 and 4.

A locking member 14 has a lever 14a and a swinging portion 14b, and is attached to the vertical portion 10a of the movable side plate 10 so as to be swingable about a shaft 16.

A torsion coil spring 15 is interposed between the locking member 14 and the vertical portion 10a, and the swinging portion 14b is pressed in the direction of arrow B by the coil spring 15.

Further, friction plates 17 and 18 having a large friction coefficient, such as rubber, are attached to the lower surface of the swinging portion 14b and the upper surface of the guide rail 12.

Furthermore, the friction plates 18 are continuously attached within the range of the dimensions of the copying material that are required to be accommodated in advance.

Therefore, due to the spring force of the coil spring 15, the friction plate 17 comes into pressure contact with the friction plate 18 as shown in FIG.
The frictional force between the two locks the movable side plate 10 at a position that matches the dimensions of the copying material.

With such a configuration, the movable side plate 10 can obtain a braking force sufficient to withstand the load applied when a large number of copy materials are placed and the sheets are passed through.

Moreover, since the friction plates 18 are continuously provided within a predetermined range, they can be locked at any position within the predetermined range, and even slight differences in dimensions within the same standard dimensions of copy materials can be reliably fixed. can be accommodated.

Further, when moving the movable side plate 10 according to the dimensions of the copying material, the operator rotates the lever 14a of the locking member 14 in the direction C against the spring force, so that the friction plate 17
．． 18 are separated, the frictional force between them ceases to act, and the braking force is released.

Therefore, the movable side plate 10 can be moved again along the guide rail 12.

In this embodiment, when the movable side plate 10 is unlocked, the separating claw is retracted in conjunction with the unlocking operation.

Hereinafter, the positional relationship between the separation claw arm and the intermediate plate will be explained together with the interlocking configuration thereof.

In this embodiment, the separation claw 3b is held by a separation claw arm 19, and this separation claw arm 19 is swingably attached to the movable side plate 10 by a shaft 4b.

Furthermore, this separation claw arm 19 is U-shaped.

One end of the opposing sides is attached by a shaft 4b, and a separation claw 3b is held at the other end.

That is, the horizontal part 19c of the separation claw arm 19 passes below the middle plate 5, in other words, on the non-loading side, and the vertical part 1
9d swings near the tip of the intermediate plate 5 on the feeding side.

Therefore, even if the movable side plate 10 is locked near a feeding means such as a feeding roller, the separation claw arm or separation claw will not come into contact with the feeding means and be damaged.

That is, the movable side plate 10 can be moved without considering the feeding means etc.
Can be locked at any position.

A side plate 10 is placed near the shaft 4b of this separation claw arm 19.
A release claw 19a projects in a substantially vertical direction.

Therefore, when releasing the movable side plate 10, the lever 14
By rotating a in the direction of arrow C, the tip 14c of the swinging portion 14b of the locking member 14 rotates upward, and in this rotation path, the tip 14C engages with the release pawl 19a.

As the lever 14a rotates in the direction of arrow C, the release claw 19a is lifted upward, and therefore the separation claw 3b held by the separation claw arm 19 also moves to the shaft 4b.
It swings upwards around the center.

That is, when storing copy materials, the copy materials are loaded on the intermediate plate 5 in advance, and the movable side plate 10 is moved according to the dimensions of the loaded copy materials, but simply by pressing the lever 14a. By simply rotating in the direction of arrow C, the separating claw can be retracted from the position of the loaded copy materials in conjunction with releasing the locking state of the movable side plate 10.

Therefore, in this embodiment, as the movable side plate 10 is moved in accordance with the dimensions of the loaded copy materials, the separation claw 3b is retracted from the position of the copy materials, so that the movable side plate 10 is moved without being obstructed by the separation claw 3b. 10 alignments are possible.

Therefore, it is possible to prevent the possibility that the stacked copy materials will be stacked incorrectly.

Furthermore, in this embodiment, by using a locking mechanism using frictional force, the movable side plate can be locked at any position, and the regulating plate such as the side plate can be fixed at an appropriate position for copying materials of any size. Can be done.

Note that the lower limit of the separation claw 3b of this embodiment is regulated by the separation claw arm 19 descending under its own weight and its lower end 19b abutting against the bottom surface 11 of the storage box, and the upper limit is further regulated by a stopper 21 attached to the bottom plate 10b. be done.

Further, the movable side plate may be separate from the side plate of the cassette body as in the above embodiment, or the side plate of the cassette body may be movable.

Moreover, one side plate or both side plates may be movable.

Moreover, even if the locking mechanism is applied only to the side plate of the cassette body, or only to the rear regulation plate,
Alternatively, it goes without saying that both the side plates and the rear regulating plate may be applied.

Furthermore, the copy material storage box includes a feeding cassette, a copy material loading table, and the like.

As described above, in the present invention, the separating claw is retracted from the position of the copying materials as the movable side plate is moved according to the dimensions of the loaded copy materials, so that the movable side plate can be moved without being obstructed by the separating claw. can be aligned.

Therefore, there is an effect that it is possible to prevent the possibility that the stacked copy materials will be stacked incorrectly.

Furthermore, since the separation claw automatically retracts upward when the restriction plate is released, there is no need for any special operation for the separation claw, making the overall operation easier.
