Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manual paper feeding device for an electric copying machine. FIG. '1 shows an example of a conventional electric copying machine. To make a photocopy using the photocopier No. 6, press the small star button. Then, the photosensitive drum 1 rotates in the direction of the arrow, and its surface is charged by the charger 2. Further, at a predetermined timing, the platen glass 3, the document 4, and the σ platen cover 5 are both reciprocated in the direction of mark loss. This original document 4 is illuminated by a lamp 6, and an image is formed on the photosensitive drum 1 via the reflected light [3L focusing optical system 7], thereby forming an electrostatic latent image. The collective optical system V consists of rod-shaped lenses arranged parallel to each other and closely spaced in a zigzag pattern, so as to form an image with the same thickness and whose top, bottom, left, and right are not reversed (erect, same-size image). It has become.

The electrostatic latent image is developed with toner particles at a location facing the developing device 8, forming a toner image. C. Paper cassette 9 (The copy paper 10 stored in this is sent out by a feed roller 11 rotating in the direction of the arrow, and is sent below the photosensitive drum 1 via a paper guide 13 with a register roller 12 interposed. The toner image on the photosensitive drum 1 is transferred onto the fed copy paper 10 by the action of the transfer device 14.The toner image on the photosensitive drum 1 after the transfer is transferred to the photosensitive drum 1 by the conductive pel 15 traveling in the direction of the arrow. \1 or C
23 The toner particles remaining on the surface of the photosensitive drum 1, which are stripped, sent to the fixing device I6 and fixed, and then discharged to the printing tray I7, are neutralized by the static eliminator '13, and then removed by the cleaning device. It is cleaned at 19.

By exchanging the copy paper 10 with the other b, it becomes easy to set copy sheets 10 of different sizes. However, even when using such an electric copying machine to copy one or two sheets of paper of different sizes, it is inconvenient that the paper sheet must be replaced. As shown in FIG. 1, some conventional electronic copying machines are capable of copying on copy sheets of different sizes with a paper cassette ε) loaded. In this electronic copy system, above the feed roller 11, a chute 20 for manually feeding copy paper, a subfield roller 21, and a handling guide 22 are provided. When copying paper of different sizes with this electronic copying machine, the paper is inserted 1 through the chute 20 and below the sub-feed roller 21 .

The small sensor in the figure detects the sloshing, and the sub-feed roller 21 begins to rotate in the direction of the arrow. As a result, copy sheets of different sizes are sent out by the sub-feed roller 21 and sent below the photosensitive drum 1 via the paper guide 13 with the register roller 12 interposed therebetween, and copying is performed in the same manner as in the normal case described above. be exposed.

In electronic copying machines such as Todorogato, feed roller 1
Since the chute 20 is provided above the paper cassette 1, a space is required for the chute 20, and when the paper cassette 9 is moved, it gets in the way. Furthermore, since 20 chutes are required, the cost is correspondingly high. There is also a model with a removable chute 20, but with this type, the chute 20 has to be attached and detached, which is troublesome, and the removed chute 20 has to be stored, which is also troublesome. .

The following explanation was made in view of the following circumstances: (b) Therefore, there is no need to install a dedicated copy paper manual feeding chute.
It is an object of the present invention to provide a manual paper feeding device that can be used for other purposes.

According to the present invention, a cassette cover is rotatably provided on a paper cassette, and the cassette cover is opened to use a chute C for manually feeding copy paper.

The invention will be described in detail below with reference to Examples.

Figure 12 is an electronic copy (representing a face) to which the embodiment of the wooden invention is applied. In this figure, parts with the same names as those in FIG.

In this electric copying machine C, exposure and development are performed in one rotation of the photosensitive drum 1 in the direction of the arrow, and transfer and cleaning are performed in the next rotation. This is carried out in the device 31. On the other hand, the copy paper 10 stored in the paper cassette 9 is sent out by the feed roller 11 which rotates in the direction of the force indicated by the arrow.

This fed-out copy paper 10 is transferred to the register roller 1-1.
? After being reversed approximately 180 degrees by a paper guide 13 with an interposed paper guide 13, the paper is sent below the photosensitive drum 1 and transferred. The copy paper 10 after the transfer is stripped from the photosensitive drum 1 by the strip finger 32, sent to the fixing device 16 via the paper knife 1/333, fixed thereon, and then discharged to the discharge tray 17. Fixing device 16 and output tray 17
is provided above the paper cassette 9 loaded in the main body 34 of the copy sheet. The paper cassette 9 has a cassette main body 35 that is open at the top.
, a paper plate 36 made of metal that is rotatably provided inside this, a rod spring 37 that urges it upward, a magnet 38 provided on the bottom plate of the cassette body 35, etc., as shown in the figure. It consists of a claw member for the paper small feed prevention 11. The paper cassette 9 is provided with a cassette cover 39. As shown in FIG. 3, the cassette cover 39 includes a rectangular cover cover 40, an arcuate paper guide portion 41 provided at the tip thereof, and a roller escape notch 42 provided therein. It consists of The cassette cover 39 is rotatably attached to a bearing 43 provided at the upper part of the side root of the cassette body 35 via a pin 44. Attachment portions 45 are provided at predetermined locations on both sides of the cassette cover 39 at appropriate inclinations, and magnets 46 are attached to these sides.

When storing the copy paper 10 in the paper cassette 9, the cassette cover 39 is placed in a fourth position outside the copying machine main body 34.
Open as shown. In this state, the paper plate 36
is pushed against the force of the bar spring 37 and is attracted to the magnet 38. As a result, the paper plate 36 is attached to the cassette main body 35.
It is kept in line with the base number of . In this state, the copy paper 10 is placed on the paper plate 361, and then the cassette cover 35 is closed as shown in FIG. This completes the storage of the copy paper 10.

To load the paper cassette 9 into the copying machine main body 34,
Notch 42 of cassette cover 39 feed roller 11
and the sub-feed roller 21 can be avoided.

Therefore, even if the paper guide portion 41 of the cassette cover 39 protrudes above the paper cassette 9, no inconvenience occurs. When the paper cassette 9 is loaded in a predetermined position, a protrusion 47 provided on the copying machine main body 34 relatively enters a hole provided in the bottom of the cassette main body 35 and projects.

At the end, the paper plate 36 is pushed up and moved upward by the front spacing spring 37 from the magnet 3B.

As a result, the copy paper 10 is pressed against the feed roller 11, and loading of the paper cassette 9 is completed.

In this state, the magnet 46 of the cassette cover 35 is located outside the copying machine main body 34.

When copying one or two copies of paper of different sizes with this electric copying machine, the cassette cover 39 of the loaded paper cassette 9 is opened. Then, the paper guide section 41 pushes the leading end of the copy paper 10 against the force of the bar spring 3l, and pushes it against the feed roller 1.
Stay away from 1. The cassette cover 39 is further opened and the magnet 46 is sucked into the copying machine main body 31. As a result, the cassette cover 39 is held in an appropriately inclined state. In this state, the cassette cover 39 is in contact with the sub-feed roller 21, and its paper guide portion 4I is located below the feed roller 11. Therefore, copy sheets of different sizes are inserted below the sub-feed roller 21 via the cassette cover 35). Then, the sensor shown in the figure κ1 detects this, and the sub-feed roller 21 begins to rotate in the direction of the arrow. As a result, the copy paper of the same size is sent out by the sub-feed roller 21, is easily placed in the paper guide section 41 of the cassette cover 39, and passes below the feed roller 11. The paper is sent to the photosensitive drum 1 through a paper guide 13 with a paper guide 12 interposed therebetween, and copies are made in the same manner as in normal printing.

The paper cassette 9 usually has a constant thickness regardless of the size of the copy paper. Therefore, even if the loaded paper cassette 9 is for small-sized copy paper, it is possible to use the cassette cover 3 to feed the full-sized copy paper.

In the above embodiment, the magnet 46 is attached to the paper cassette cover.
31) is held in an open state, but the present invention is not limited to this, and for example, a detachable locking fitting may be used. Alternatively, the cassette cover 31) may be held in the open state by holding it by hand, without using the magnet 46 or the like.

In the above embodiment, the paper cassette 9)
However, the present invention is not limited to this, and it may be provided on the opposite side as in the conventional example shown in FIG. In this way, the paper cassette 9 can be easily replaced.

As described above, according to the present invention, the cassette cover of the paper cassette can be used as a sheet feeder for feeding copy sheets in parallel, so that a dedicated chute is not required.

Therefore, space can be used effectively and costs can be reduced. In addition, since all you have to do is open the cassette cover, operation is easy, and there is no need to store it.
