Description

[Detailed Description of the Invention] <Technical Field> This invention relates to an improvement of a cover device that covers a part of various devices and devices.

<Prior Art and Its Disadvantages> A document cover in a copying machine is used as follows. First, open the document cover, place the document on the document table, close the document cover, and make a copy.
After copying is completed, release the document cover again and remove the document on the document tray. Further, the front cover is opened and closed when inspecting the inside of the apparatus, such as when a paper jam occurs during copying. In this way, various types of equipment and devices are provided with various types of covers that can be opened and closed.

When attaching such a cover to the main body of the device in a rotatable manner, a large number of parts are used, such as a rotation shaft, a shaft holder for fixing the shaft, a bearing, a bearing holder, and a fixing screw for fixing the holder. Furthermore, as mentioned above, the cover device with a rotating shaft used in various devices and devices is composed of many parts, so the cost of the multiple component parts and the time required to assemble the multiple parts are required. It had become an expensive device.

<Purpose> In view of the above-mentioned conventional problems, the present invention has been developed to
An object of the present invention is to provide a cover device for an apparatus that requires less assembly steps and is inexpensive.

<Example> FIGS. 1 to 3 are examples of the present invention. Fig. 1 is a perspective view showing the appearance of a copying machine equipped with a cover device according to the present invention, Fig. 2 is an explanatory diagram of the main parts of the cover, and Figs. It is an operation explanatory diagram.

An embodiment in which the present invention is applied to a copying machine will be described in detail below.

In FIG. 1, a document cover 2 is provided on the top of a copying apparatus main body 1 so as to be rotatable about shafts 3a and 3b, corresponding to a transparent plate on which a document is placed. Similarly, the front cover 4 of this copying apparatus is
It is rotatably provided around shafts 5a and 5b as fulcrums. For details of these shaft bodies 3, 5 and bearing parts, a cross-sectional view taken along line X-X' is shown in Figure 3A.
Details will be explained later.

FIG. 2 is a view of the document cover 2 viewed from the bottom. The document cover 2 is made of resin with a thickness of about 0.5 mm to 3 mm, and can be elastically deformed. At one end of the document cover 2 are shaft bodies 3a, 3 each consisting of a cylindrical shaft and a support for supporting the shaft.
b, and a slip-off prevention member 6 for preventing the shaft from slipping off are integrally molded in a substantially linear shape. or,
A white mat 7 is attached to the center of the document cover 2 to press the document directly onto the document table.

FIG. 3A shows a state in which the document cover 2 is attached to a support plate 8 provided on the main body of the copying apparatus, and is a sectional view of a main part taken along line X-X' in FIG. 1. FIG. 3B is an explanatory diagram of the attachment and detachment of the document cover 2 according to the present invention, in which the document cover 2 is attached to the support plate 8.
FIG. 2 is a cross-sectional view of main parts showing a state in which the document cover 2 is elastically deformed in order to be attached to the document cover 2. FIG.

The support plate 8 is fixed at the upper part of the main body 1 of the copying apparatus, particularly at a position corresponding to one side of the transparent plate. Bearings 9a and 9b having openings formed corresponding to the shafts 3a and 3b of the document cover 2 are attached to the support plate 8. Further, a slip-off prevention opening 11 is formed in the center between the bearings 9a and 9b, corresponding to the slip-off prevention member 6 formed on the document cover 2. This slip-off prevention opening 11 is formed in a shape slightly larger than the slip-off prevention member 6 so that the slip-off prevention member 6 can be inserted therethrough. Further, the distal end portion 6a of the falling-off prevention member 6 is formed so as not to impede the rotation of the document cover 2.

The slip-off prevention member 6 is formed to have a length that projects downward from the support plate 8 by an amount L when the document cover 2 is attached as shown in FIG. 3A. Further, the length of the end fitting portion of the shaft bodies 3a, 3b is long enough so that the shaft bodies 3a, 3b do not come off from the bearing due to the play between the slip-off prevention member 6 and the edge of the opening 11. It's summery.

Next, the operation for attaching and detaching the document cover 2 will be explained.

When attaching the document cover 2 of FIG. 2 so that it can be rotated as shown in FIG. 3A, first, hold both axial ends 2a and 2b of the document cover 2 with your hands.
As shown in FIG. 3B, both ends in the axial direction are elastically deformed so that the surface on which the shaft is provided faces inside. In this state, the center of the shafts 3a, 3b of the document cover 2 is connected to the bearings 9a, 9b provided on the support plate 8.
match the center of Next, the document cover 2 is attached to the shaft 3,
It is moved along the center line of the bearing 9. At this time, the distal end portion 6a of the falling-off prevention member is initially in contact with the upper surface of the support plate 8, but after slidingly moving on the support plate 8 for a predetermined distance as the document cover 2 moves, the tip portion 6a of the falling-off prevention member It can be inserted into the opening 11 provided in the. Then, when the elastic deformation of the document cover is released,
The falling-off prevention member 6 is inserted into the opening 11, and as shown in FIG.
The document cover 2 is attached to the main body of the copying machine so as to be rotatable about shafts 3a and 3b.

Further, the document cover 2 can be removed from the main body of the copying apparatus by performing an operation opposite to that described above. That is, both ends 2a of the document cover 2,
2b, elastically deform the original cover 2 until it comes out of the opening 11 of the support plate 8, and then move the original cover 2 to the right in FIG.

In this way, the distal end 6a of the slip-off prevention member 6 is provided between the shafts 3a and 3b so as to protrude from the insertion position of the shaft, so when the document cover 2 is not elastically deformed, 6b comes into contact with the edge of the opening 11 of the support plate 8, and movement of the document cover 2 in the axial direction is restricted. That is,
The shafts 3a and 3b provided on the document cover 2 are connected to the shafts 3a and 3b provided on the support plate 8.
It is not possible to move the bearings 9a and 9b in the axial direction to a position where they can be supported.

The above-mentioned cover attachment mechanism is the same for the cover portion, so a detailed explanation will be omitted.

In the above embodiment, the cover 2 or 4 is made of an elastic member, but the support plate 8 may be made of an elastic member that can be elastically deformed. Also, the shaft and bearing may be placed as a pair on either the cover or the main body side.
Furthermore, the slip-off prevention member and the opening may also be placed on either side of the cover body. Even in the case of each of these combinations, the above-mentioned slip-off prevention effect is achieved.

<Effects> According to the cover device of the present invention, the attachment mechanism for covers of various devices and devices can be simplified and configured with a reduced number of parts. Therefore, the number of man-hours required to assemble the cover device can be reduced, the assembly time can be shortened, and an inexpensive cover device can be provided.

In addition, the cover does not fall off accidentally due to the fall prevention mechanism, so you can use it with confidence.
