JPS58172130A - Paper-feeding cassette also usable for catch tray - Google Patents

Abstract

PURPOSE:To remove the loading and unloading of a paper-feeding cassette and a tray and minimize the loading space by providing side walls closely attachable to both outside walls of a container box on both sides of the return part of the cassette for forming the paper-feeding cassette commonly usable as a catch tray. CONSTITUTION:A half-fixed lid 5 and a rotary lid 8 are provided at the opening part of a container box 1. The rotary lid 8 is provided with side walls 12 and 13 on its both sides to be slided with both outside faces of the box 1, while ribs 14, 14... are set up at proper positions in its inside. When the rotary lid 8 is turned to be folded back on the backside of the lid 5, the upper face of a paper-feeding cassette inserted into a paper-feeding part can be used for a receiving tray of papers 16 discharged through the inside of the lid 8 and the backside of the lid 5, and discharged papers are prevented by both side walls 12 and 13 of the lid 8 from coming off. This construction permits to disuse the catch tray to receive discharged papers, and save the labor and the space to load and unload the cassette and the catch tray separately.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a copying machine that uses a cut sheet as a copying paper;
Related to paper feed cassettes for facsimile machines, printers, etc.

2. Description of the Related Art Conventionally popular compact copying machines, facsimile printers, and other machines that use cut sheets as copy paper generally use paper feed cassettes for convenience when converting paper sizes.

In addition, these paper feed cassettes are equipped with a lid on the paper storage box to prevent the paper from becoming damp, especially in machines that use electronic copying (recording method). In many cases, the core is opened to expose the stacked paper, and a paper feed roll is pressed against the core.

On the other hand, in consideration of the space factor when using such a cull-type copying machine in a small business office, etc., it is preferable to eject the copy paper that has finished recording near the top of the paper feed cassette. When the machine is not in operation, the paper feed cassette and ejected paper catch tray are often removed.

In this case, it is not only cumbersome to remove and store both the paper feed cassette and the catch tray, but also requires a large amount of storage space.

The present invention has been made in order to solve the above-mentioned drawbacks of the conventional machine shuttle. To provide a paper feed cassette that can also be used as a catch tray, in which ejected close-up paper can be stored without falling by providing side walls that can come into close contact with both outer walls of a copy paper storage box on both sides of the copy paper storage box. .

The present invention will be explained in detail below based on the drawings.

FIG. 1 and FIG. 2 are a plan view and A-A showing an example of a paper feed cassette that also serves as a catch tray according to the present invention, respectively.
FIG.

In this figure, a copy paper stack storage box 1 is provided at its bottom with a swingable paper table 2 rotatably via a hinge 3 for pressing the stacked paper against a paper feed roller (not shown), and furthermore, the A Y through hole 4 with a lever shown in the figure for pushing up the paper tray 2 is provided.

On the other hand, the opening of the box 1 is provided with a semi-fixed lid 5 and a rotating lid 8 rotatably connected to this lid by a hinge 6.7,
As mentioned above, when copying is not to be performed, the cylinder is normally removed from the copying machine and the cylinder is closed to prevent the accumulated paper from absorbing moisture. .

The semi-fixed lid 5 is forced into a semi-fixed state by inserting its rear edge into the groove 9 provided at the rear edge of the box 1, and when the rotating lid 8 is opened, the entire lid is It is constructed to prevent it from falling out of the box, and ribs 10, 10, . . . are provided at appropriate places on the back surface for the purpose described later.

Further, outer surfaces 11 of the box 10 are provided on both sides of the rotary lid 8.
When the side walls 12 and 13 that slide are provided, ribs 14, 14, . . . are erected at appropriate locations on the inner surface of the lid.

It should be noted that this paper feed cassette cannot be inserted into the copying machine up to the boundary between the tube covers 5 and 8.

The paper feed cassette of the present invention constructed as described above functions as explained below.

That is, as shown in FIG. 3, the top surface of the paper feed cassette inserted into the paper feed section of the copying machine 15 with the rotating body 8 rotated and folded back to the back of the semi-fixed lid 5 is immediately rotated. The inner surface of the lid 8 and the back surface of the semi-fixed lid 5 serve as a receptacle for the copy paper 16 that is discharged after recording is completed, and is used as a tray.
Moreover, there is no possibility that the ejected paper will fall off due to the vertical walls 12 and 13 of the eight rotating lids.

Furthermore, the ribs 10 and 14 have the effect of preventing the ejected copy paper 16 from coming into close contact with the flat surface of the cylinder lid 5 or 8, and since the ribs 10 and 14 are stepped, even short sheets of paper can be Even long sheets can be easily handled, and the rod is convenient for removing stacks of ejected sheets. The above-mentioned effect is particularly remarkable in the case of recording devices that use static electricity, such as electrophotographic copying machines and facsimile machines. If the paper is ejected, there is a risk that the paper may slip into the paper feed section.

If such a concern is anticipated, as shown in FIG. When the rotating lid 8 is folded back, the operator can prevent the ejected paper from slipping down by standing the opening as shown by the dotted line.

As shown in FIG. 5, there is a slip-off prevention member 18 that engages with the rotating lid 8 which is folded back at a proper position on the machine body.
may be installed.

Since the present invention is constructed as described above, it is possible to use a small copying machine, a printing machine, a printer, or a machine that uses a paper feed cassette, which requires a good space factor, to eject paper. Since it is possible to eliminate the need for a catch tray to catch paper, it is possible to save the time and space of separately removing and storing the paper feed cassette and catch tray when the machine is not in use, and it is also extremely effective in terms of reducing machine costs. It is.
