Description

[Detailed Description of the Invention] -Technical Field- The present invention relates to a body structure of an image recording apparatus such as an electrophotographic copying machine, and more particularly to a body structure for removing recording paper caught inside the body.

-Prior art- Recently, electrophotographic copying machines have been provided with a removable recording paper holder at the bottom of the machine body in response to the demand for miniaturization of the equipment, and the recording paper stacked on this recording paper holder is transferred to the machine body. A structure is being planned in which the paper is fed out using a paper feed roller built into the lower part of one side.

By the way, an electrophotographic copying machine with such a structure has a front cover that allows the inside of the machine to be opened to the outside so that the user can remove the jammed paper, and a side surface near the paper feed roller position where the recording paper is easily caught. However, if the paper holder is carelessly pulled out during paper jam processing when some paper remains in the paper holder, the jammed paper may be torn and left inside the machine. The internal equipment was damaged by the paper that was pushed to one side.
A serious accident will result.

-Object and structure of the present invention- The present invention provides an image recording apparatus having a pull-out type recording paper holder as described above, which has a body structure that prevents the recording paper holder from being pulled out inadvertently during jam processing. The jam is located under the machine so that the paper holder to which the paper is attached can be pulled out toward the front, and is equipped with an arc-shaped guide plate and a sorting member that face the paper feed roller at the bottom of one side of the machine. In an image recording device in which a side cover for release is releasably attached to the machine body, the front cover covering the front side of the machine body is placed at the bottom of the machine body so that a part of the front cover is located horizontally in front of the recording paper holder when released. An image recording device is proposed that is releasably supported by a hinge and that prevents the recording paper holder from being pulled out when the side cover is released by engaging the locking piece of the side cover with the front cover in the closed position. It is.

-Embodiments of the present invention- Hereinafter, details of embodiments of the present invention will be described with reference to the drawings.

In FIGS. 1 and 2, a document table 2 that can reciprocate in the left-right direction is located at the top of the copying machine body 1, and the recording paper a on which images are recorded inside the machine body 1 is ejected on the left side of the machine body 1. The paper is taken out onto the paper tray 3.

Immediately below the copying machine body 1, that is, between the legs 4A and 4B, a recording paper holder 5 is incorporated which can be pulled out from directly below the body 1 toward the front. The same recording paper holder 5
As shown in the second figure, the grooves 5A and 5A of the legs 4A and 4B,
5B, and the recording paper cassette 6 containing recording paper can be replaced in the drawn out state as shown. A flip-up lever 9 is provided on the right side of the recording paper holder 5 to direct the bottom plate 7 of the recording paper cassette 6 toward a paper feed roller 8, which will be described later. The spring lever 9 is fixed to the middle part of a spring shaft 10 extending in the front-rear direction on the right side of the recording paper holder 5.
A driven lever 12 controlled by a paper feed control mechanism 11 shown in the fourth figure is fixed to the rear end.
On the other hand, the front face of the copying machine body 1 has a front cover 14 whose lower part is attached to the body 1 with hinges 13A and 13B. It is opened and the recording paper a caught inside the machine can be removed.
Further, when the front cover 14 is in the open state, the front cover 14 is located horizontally in front of the recording paper holder 5, and therefore, drawing out of the recording paper holder 5 is prohibited. vice versa,
When the recording paper holder 5 is pulled out, the front cover 14
Since it is not possible to completely open the door, jamming cannot be performed.

3 and 4 show a paper feeding device that feeds the recording paper a in the recording paper cassette 6. It has a paper roller 8. This paper feed roller 8 is fixed approximately at the center of a paper feed roller shaft 16 that is rotatably wrapped around the front and rear frames 15A and 15B of the machine body. A plurality of auxiliary rollers 17 having the same diameter are located. Further, on the inner surface of the side cover 18 shown in FIG. A shaft 21 is attached. Note that the operation of the driven lever 22, paper feed roller shaft 16, and driven lever 12 provided at the shaft end of the sorting shaft 21 is controlled by the paper feed control mechanism 11, although a detailed explanation will be omitted since this is not the gist of the present invention. Ru.

On the other hand, the side cover 18 has a locking piece 23 protruding from the front end, and this locking piece 23 is received in the engagement groove 24 of the front cover 14 in the closed position as shown in the fourth figure. There is. Therefore, since the side cover 18 cannot be opened unless the front cover 14 is opened, the side cover 18 can only be opened when the recording paper holder 5 is in the completely retracted position.

Since the above embodiment has the above structure,
The front cover 14 and side cover 18 cannot be opened unless the recording paper holder 5 is completely retracted under the body 1. Therefore, if the recording paper a is caught inside the machine, the jammed paper can be removed by opening the front cover 14 and then opening the side cover 18. Of course, during this jam processing, the open front cover 14 is positioned in front of the recording paper holder 5, so that the recording paper holder 5 is prevented from being pulled out carelessly and causing a serious accident. Ru.

-Effects of the present invention- According to the present invention, the side cover is opened on the condition that the front cover, which can intervene during the pull-out trajectory of the paper holder, is opened. Serious accidents caused by being pulled out can be prevented.
