[Problems to be Solved by the Invention] The present invention solves the above-mentioned conventional problems, allows the device to be placed on the device without using any special members, and without creating a space between the device and the placement surface, and has a finger rest. An object of the present invention is to provide a frame for an image forming apparatus that has a simple base member.

[0005]

[Means for Solving the Problems] The present invention solves the above problems by providing a frame for an image forming apparatus having a base member placed on an installation surface and a machine frame member fixed on the base member. In the body, a first recess is formed to be inwardly recessed in the peripheral edge of the base member and penetrate in the vertical direction; A recessed second recess is formed, a wall surface of the second recess of the machine frame member is formed as a handle, and a space formed by both the recesses in the base member and the machine frame member forms a finger insertion space. The problem has been solved by a frame of an image forming apparatus characterized by the following.

[0006]

[Operation] According to the present invention, one empty space is formed by the inwardly recessed first recess formed in the base member and the upwardly directed second recess formed in the machine frame member fixed to the base member. A finger insertion space is obtained, and the upper wall of the second recess formed in the machine frame member is formed as a handle.

[0007] Even when the base member is placed closely on a mounting surface such as a table, it is possible to easily place a finger on the base member, and no special member is required, so that a low-height and inexpensive device can be formed. is now possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be explained based on the embodiments shown in the drawings.

In FIGS. 1 and 2, a frame 1 of the image forming apparatus, for example, a frame 1 constituting a cassette storage section to which a paper feed cassette 50 can be detachably attached, is a base that is placed on an installation surface D such as a desk surface. The member 2 and the machine frame member 3 fixed to the base member 2
and has.

The upper surface 2a of the base member 2 has a paper feed cassette 5.
0 is formed as a flat surface without any protruding members so that it can slide. A flange 4 projecting downward from the peripheral edge of the base member 2 is formed by bending by drawing or integrally formed with the base member 2 by welding or the like.

Three to four rubber feet 5 are fixed to the lower surface of the base member 2, and the rubber feet 5 are placed on the installation surface D.

A shaft 8 is rotatably supported in a hole 7 formed in an ear 6 formed by bending a part of the base member 2 downward.
A lifting arm 9 is fixed to the shaft 8. The rising arm 9
is formed to be able to protrude upward through an opening 10 formed in the base member 2, and pushes up the bottom plate 52 of the paper feed cassette 50 placed on the top surface of the base member 2, and pushes up the paper P placed on the bottom plate 52. It comes into pressure contact with the paper feed roller R provided on the machine frame member.

The base member 2 has a plate thickness of 0.5 to 2 mm, for example.
The opening 10 and the reinforcing recess 11 are formed by drawing sheet metal processing of the plate material.

A first recess 12 recessed inwardly is formed at a position suitable for carrying the base member 2 and the collar 4 so as to penetrate vertically. The first recess 12 is formed in a shape and size convenient for inserting a finger from the outside. The flange 4 protrudes downward with almost no space between it and the base D.

The machine frame member 3 is placed on the base member 2, and the hole 1 in the flange 3a formed by bending on the outside of the machine frame member 3 is
The base member 2 is fixed by screwing the screw inserted into the base member 3 into the screw hole 14 of the base member 2. It is also possible to fix by welding instead of fixing with screws. When fixing the machine frame member 3, the base member 2 of the machine frame member 4 is inserted into the positioning hole 15 formed in the base member 2, as shown in FIG. Performs relative positioning. The positioning hole 15 is formed in a substantially M-shape so that the gap t between the protrusions 15a and 15b from both sides is equal to the plate thickness t of the positioning tongue piece 16. By making the length W of the positioning hole 15 substantially equal to the width W of the positioning tongue piece 16, displacement after installation is prevented.

A second recess 17 recessed upward is formed in the flange 3a of the machine frame member 3 at a portion opposite to the recess 12 of the base member 2.

When the machine frame member 3 is fixed to the base member 2, as shown in FIG. A cavity B is formed, and it becomes possible to easily insert a finger. As shown in FIG. 2, a first recess 12 and a second recess 17 are formed at two opposite positions, and the upper wall 17a of the second recess 17 of the machine frame member 3 is formed as a handle, and a finger is placed on the upper wall. By hanging, the frame body 1 having the machine frame member 3 and the base member 1 can be easily lifted on both sides.

The lower end of the base member 2 and the installation surface D do not require any special parts as a handle, and in order to make it easy to hold the hand.
There is no need to attach tall rubber feet to create a space between the two.

As shown in FIG. 5, an exterior cover 18 is further attached to the machine frame member 3, and a finger hook recess 19 and a finger hook protrusion 20 are formed in the exterior cover 18.
9 into the first and second recesses 12 and 17 described above.
It can also be configured to fit in. Exterior cover 1
8 is conveniently made of plastic because it is easy to mount.

The second recess 17 of the machine frame member 3 is formed as a flange bent outward as shown in FIG. 2, whereas the flange 3a is bent inward as shown in FIGS. 6 and 7. form,
It is also possible to fix it to the base member 2 with the flange 3a and form the second recess 17 as a notch. In this case cover 1
8, it is deformed from FIG. 5 as shown in FIG. 8.

[0021]

[Effects of the Invention] According to the present invention, the first recess formed in the base member and the second recess formed in the machine frame member form a space for hanging fingers and a handle, so it is sufficient to use low rubber feet. You can put your finger on it. Moreover, since a special handle member is not required and the flange of the base member is not cut out, a sufficiently secure state can be ensured in terms of strength. Since no special members are required, it is also advantageous in terms of cost.

[0022] According to the present invention, even when the exterior cover is attached, the same recess can be used as the exterior cover hooking portion and the finger hooking portion, and a good-looking product can be obtained.

Strength can be maintained by forming a concave portion without cutting out the flange formed on the periphery of the base member, and since the flange has a downwardly protruding shape, the base surface extends within the height of the flange. The reinforcing aperture recess and the mechanism that acts on the paper feed cassette can be accommodated, making it possible to use space effectively.

By shaping the flange to project downward, the upper surface of the base member can be directly used as a sliding surface for the paper feed cassette, and the strength can be maintained since there is no need to cut out the flange to remove and remove the paper feed cassette.

According to the present invention, the overall height of the image forming apparatus can be reduced, and space can be saved.
