Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording apparatus including an electrophotographic copying machine in which recording accessories such as a paper feed unit can be attached to the lower part of the main body.

BACKGROUND OF THE INVENTION In recent years, electrophotographic copying machines have become increasingly used to copy not only general documents but also large-scale drawings and maps of various sizes, and as a result, the demand for copying machines with a variety of copying surfaces has increased. ~be. Copying machines such as this one can use recording paper of various sizes, so the paper cassettes installed in them also come in a wider variety of paper cassettes compared to general copying machines.
If all of these paper feed cassettes are directly manufactured within the copying machine main body, the copying machine main body will have a larger volume, which will be uneconomical in terms of manufacturing and transportation, and furthermore, proper operability will be lost in terms of handling.

Therefore, in the case of such a copying machine, as shown in FIG. 2 and thereby the front HL1 copy body, its contents.
! Measures are taken to keep R small without increasing it.

However, conventionally, a paper feed unit (not shown) for guiding the paper feed force sensor) 1 to the boat section of the copying machine main body 2 and maintaining its position has been passed through the space of the pedestal 3. It was attached directly to the bottom of the copying machine main body 2 by screwing or the like.

This installation form requires supporting the paper feed unit, which is relatively heavy, until the installation is completed, so it is difficult for one person to work alone, and it is difficult to install screws in a narrow space. The work was extremely inefficient.

In addition, since the installed paper feed unit is positioned only by screws, its installation accuracy is poor, and the installation position of the paper feed cassette that is guided by it is also inaccurate, making smooth paper feeding impossible. It had drawbacks.

Purpose of the Invention The present invention provides a guide for the paper feed cassette at the bottom of the copying machine main body.
The object of the present invention is to provide a recording attachment member 2 for holding the recorder, which can be easily and quickly attached with good precision.

Structure of the Invention The present invention is configured such that the +I member for recording can be attached to the copying machine main body after being inserted into the copying machine main body as a guide, and it is attached to the lower part of the main body of the recording device. In a recording apparatus in which a recording attachment 6 member is disposed in a recording apparatus, a guide section for guiding the recording attachment 6 member to a predetermined mounting position at a lower part of the recording apparatus main body on a part of an operation stand on which the recording apparatus main body is placed; This is achieved by the recording device C, characterized in that a retaining portion for engaging the recording attachment member and the recording device main body is provided at the final fixing position of the mounting operation of the recording attachment member.

Embodiment FIG. 2 is a sectional view of a main part showing one embodiment of the attachment of the six recording members in the recording apparatus according to the present invention.

In FIG. 2, a recording device, that is, a copy sheet 1 main body 12, has an opening 12a on its bottom surface leading to a recording paper feeding section, and an engaging section 1- for attaching a recording attachment 6 member 14, which will be described later. That is, it is provided with a stay 12b.

Further, on the pedestal 13 on which the copying machine main body 12 is placed,
`` indicates a pair of guide portions, that is, guide plates 1 provided at the front and back in the figure for guiding and introducing the recording attachment member 14.
9 is fixedly attached.

On the other hand, the recording attachment 8 member, that is, the paper feed unit 14, which consists of a pair of side plates 14b connected by a front plate 14aK and having the contours shown in the figure, has a notch 17n to be engaged with the stay 12b. The provided protrusion 17 and the guide plate 19
A pair of rollers 18 are provided, each of which is moved by being placed on the upper edge of the roller. Furthermore, the paper feed unit 14 includes a portion (M not shown) that holds the paper feed cassette 11, and a first feed unit for feeding one sheet of recording paper from the paper feed cassette 11 to the copying machine main body 12. Paper roller 15, second boat feeding roller 1
6 is provided.

In the present invention, the paper feed unit is first attached to the mount 1.
If you insert from 11111 on the right side of 3, IJ crawler 18
Move above the guide plate 19 RK Q, and the guide plate 1
By raising the slope part 19a of 9, the protrusion 1
7 enters the opening 12a VC of the copy t3 main body 12 and occupies a position opposite to the stay 12b. When the paper feeding unit 14 is further inserted, the protrusion 17
The notch 17a provided in the stay 12b engages with the stay 12b to stop the paper feeding unit. This position is the final fixing position for the installation operation of the paper feeding unit 14, and since the front plate 14a is made so as to be in contact with the front surface of the copying machine main body 12, zero The paper feed unit 14 is fixedly attached to the copy tower main body 12 by a set screw 20. Note that since the guide plate 19 and the rollers 18 are provided on both sides, the guiding operation is smooth.

As is clear from the above description, in the recording apparatus according to the present invention, when installing the paper feeding unit that guides the paper feeding cassette into the recording apparatus, the paper feeding unit that guides the paper feeding cassette can be mounted by the guide section provided on the pedestal, and the paper feeding unit can be finally fixed. Since the position is secured by the stay IC, which is a retaining member, installation is extremely easy, and the Hi:! Since it is fixed by a retaining part provided in another device and screwed to the front surface of the device, the accuracy of handling is also significantly improved.

The paper feed unit thus installed) 14K makes it possible to install a paper feed cassette that cannot be directly attached to the recording device, and the Mfi H+ paper cassette record
EJ+? fE is the first
, one sheet is fed into the recording apparatus by the second feeding rollers 15 and 16 through the frontage section 12 ti. Effects of the Invention According to the present invention, the recording material is used to feed one sheet into the recording apparatus. By providing a recording device in which the unit can be easily and accurately mounted, the recording device allows copying onto a large number of sheets of recording paper without having to replace the paper feed cassette one by one. Jin: 1 said it was possible.
