Description

[Detailed description of the invention] The present invention provides a feeding cassette for storing copy materials, etc.
This invention relates to a feeding cassette that can feed various types of copying materials with one feeding cassette.

Recently, a cassette system has been devised for copying machines and the like in order to streamline and speed up office work.

In the conventional method, various types of copy materials of different sizes are stored in dedicated cassettes, and as needed,
The cassette is used by loading it into a feeding device such as a copying machine.

However, with this method, copying materials can be easily replaced by replacing the cassette, which is efficient, but since the cassettes are dedicated, they must be prepared according to the size of each copying material, and they cannot be used. This requires a place to store the cassette, which is undesirable in terms of moisture and dust resistance.

Therefore, the present invention provides a feeding cassette that can feed many types of copy materials of different sizes with one feeding cassette.

That is, the present invention, which is distantly related to the above object, has a side plate that regulates the side edges of the copy material and is movable according to the width size of the copy material, and a side plate that is divided into a plurality of parts to hold the copy material and has a side plate that controls the side edges of the copy material and that is movable according to the width size of the copy material. a holding plate that is movable and moves the feeding side in the vertical direction according to the movement of the holding plate; and a swingable holding plate that is provided on the feeding side that engages with the plurality of divided holding plates and simultaneously lifts the holding plate feeding side. The present invention is characterized by having a plate-like member, and a pushing means for pushing up a plurality of divided holding plates to substantially the same height via the plate-like member during feeding.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

In FIGS. 1 and 2, 1 is a cassette main body, and 2 is a reference side plate that is fixed to the cassette main body 1 and serves as a reference for determining the position of a copying material.

A separating claw 3 for separating copy materials one by one is swingably attached to the reference side plate 2 on the feeding device 10 side of the copying machine main body.

Reference numeral 4 denotes a movable side plate that can be moved in the direction of arrow C depending on the size of the copying material, and is slidable along a guide plate 5 installed approximately in the center of the cassette body. A separating claw 3' for separating copy materials one by one is swingably attached to the feeding device 10 side.

The middle plate 6 on which copying materials are loaded swings around a shaft 7 provided on the cassette body 1, and the middle board 8 similarly swings around a shaft 9 fixed to the movable side plate 4. It is adapted to move integrally with the movable side plate 4.

Furthermore, a plate-like member 13 having spring seats 12 and 12' screwed to the middle plate 6 is extended to the push-up springs 11 and 11' installed in the cassette on the side of the feeding device 10,
The middle plate 6 is configured to move up and down together with the plate member 13.

This middle plate 6 is pushed up with springs 11 and 1 centered around the shaft 7.
1' is constantly pushed upward, and the separation claw 3.
It comes into pressure contact with 3' and stops.

Further, the feeding device 10 side of the intermediate plate 8 rests on the plate-like member 13, and the push-up spring 11 is inserted through the plate-like member 13 around the shaft 9.
・The movable side plate 4 is constantly pushed upward by 11'.
It slides on the upper surface of the plate-like member 13 along with the movement.

Furthermore, the movable side plate 4 can be moved along the guide plate 5 according to the size, that is, the width, of the copying material, and the lock is such that the stopper plate 20 enters the stopper square hole 14 provided in the guide plate 5. It is carried out by

Reference numeral 15 denotes a regulating plate that can be moved according to the size, ie, length, of the copying material, and is attached to the upper surface of the intermediate plate 6 and is movable in the D direction.

This locking is performed by the stopper plate 16 entering the stopper square hole 17 provided in the middle plate 6.

Reference numeral 18 designates a paper press pad for aligning copying materials and making it easier to separate them one by one, and reference numeral 19 a moisture-proof/dust-proof lid.

When loading copying materials into the feeding cassette as described above, the regulation plate 15 is slid in the direction of the arrow in accordance with the size of the copying material to be loaded, and is locked with the stopper plate 16.

Similarly, move the movable side plate 4 to the guide plate 5 according to the size of the copy material.
Slide the stopper plate 20 in the direction of arrow C along
to lock.

Next, copy material is placed on the upper surface of the middle plates 6 and 8, and when pushed down by hand against the push-up springs 11 and 11' to near the bottom of the cassette body 1, the copy material is removed from the separating claws 3 and 3. ′
Enter the bottom of the.

When the hand is released, the intermediate plates 6 and 8 are pushed up via the plate member 13 by the pushing up force of the pushing up springs 11 and 11', and the copying material is pressed against the lower surface of the separating claws 3 and 3' and fed. It is in a sending state.

The above one fixes the reference side plate 2 to the cassette body 1,
Although the movable side plate 4 is slid along the guide plate 5, the plate member 13 is made to move up and down independently, and the middle plate 6 is made swingable relative to the reference side plate 2.

Then, the tip of the intermediate plate 6 may be placed on the upper surface of the plate-like member 13 to be slidable, and the intermediate plate 6 may be moved while the reference side plate 2 is slid along the guide member.

With the above configuration, the present invention has the following effects.

([) A single cassette can feed copy materials of different sizes.

That is, in the present invention, the side plates regulate the side edges of the copy material and are movable according to the size of the copy material.

Therefore, a single cassette can feed copy materials of different sizes.

Therefore, for example, the trouble of having to prepare a plurality of cassettes according to each size of copy material processed in a copying machine is eliminated, and there is no need for a place to store cassettes of other sizes that are not used.

(ii) Even though copying materials of different sizes are fed using the cassette -1-, stable and reliable feeding can be achieved.

That is, in the present invention, during feeding, the holding plate on which the copy material is loaded is pushed up by the means for pushing up the holding plate to approximately the same height.

For this reason, for example, compared to pushing up the entire cassette (in this case, you have to push it up against the entire weight of the bottom plate, side plates, rear control plate, etc. of the cassette), It can be easily adjusted so that it always has a predetermined pressure contact with the outer circumference of the roller and feeds from the same feeding position.

Therefore, even though copying materials of different sizes are fed with a single cassette, stable and reliable feeding can be achieved.
