Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a rattling prevention device for attaching an exterior cover or the like to the outside of a body frame of an electrophotographic copying machine or the like.

(Prior Art) Conventionally, methods for attaching an exterior cover to the main body frame of this type of machine include a method of screwing the four corners of the cover to the main body frame using screws, and a method of attaching the outer cover to the main body frame using screws. The method used was to attach hooks to the corners, use the hooks to attach the cover to the main body frame, and fix the remaining two corners to the main body frame with screws, but in the former method, the ease of attaching and detaching the cover to the main body frame was adopted. However, although the latter is easy to put on and take off, it has the drawback of not being able to absorb looseness caused by gaps in the hooks that fix the cover to the main body frame.

(Object of the Invention) The present invention has been made to eliminate the drawbacks of the above-mentioned conventional law for attaching an exterior cover to the body frame of a machine such as an electrophotographic copying machine. A sliding method using a hook is adopted as a method, which allows the exterior cover to be easily and quickly attached to and removed from the main body frame, and also allows the cover to be attached to the main body frame without spoiling its beauty. The attachment of the cover is intended to eliminate backlash.The attachment of the outer cover of an electrophotographic copying machine, etc. is intended to provide a backlash prevention device.

(Structure of the Invention) For this purpose, the present invention provides a mounting device in which an exterior cover of an electrophotographic copying machine or the like is made detachable by sliding it up and down on the machine body frame using a bracket. A flanged stud is installed in the appropriate place, and an elastic hook such as a plate spring is provided at the appropriate place on the back side of the exterior cover with a mounting groove such as an inverted U shape for locking onto the flanged stud of the main body frame. When the exterior cover is attached and slid from above to the bottom of the main body frame, the flanged stud of the main body frame is elastically fitted into the hook mounting groove of the exterior cover, and the cover is attached to the main body. It can be easily and quickly attached to the frame without any rattling, and when the cover is slid upward, the hooks of the cover can be easily removed from the flanged studs on the body frame, allowing the cover itself to be easily and quickly removed from the body frame. It is designed so that it can be removed.

(Example) The present invention will be described in detail below based on an example shown in the drawings.

FIG. 1 is a partially sectional side view of the device for preventing rattling when installing an exterior cover, etc. of the present invention, and FIG. 2 is a rear view showing a state in which the device is used to fix the exterior cover, etc. to the main body frame.

In a cover mounting device in which an exterior cover 2 is removably attached to a main body frame 1 of a machine such as an electrophotographic copying machine by sliding it vertically using a hook, two outer corners of the upper or lower outer corner of the main body frame 1, Alternatively, the flanged studs 3 are attached to all four corners, and the rear surface of the exterior cover 2 is provided with saw-tooth disconnectors at appropriate places, and the lower part is inverted U-shaped for inserting and locking the flanged studs 3. An elastic hook 5 such as a plate spring having a mounting groove 4 is fixed by spot welding or the like. As a result, the main body frame I
To attach the IC exterior cover 2, all you have to do is align the mounting groove 4 of the hook 5 of the exterior cover 2 with the flanged stud 3 of the main body frame 1, and then slide the cover downward. As shown in FIG. 3, the hook 5 of the exterior cover 2 is not only locked by inserting the flange portion of the tip of the flanged stud 3 of the main body frame 1 into the mounting groove 4, but also connects the hook 5 with the exterior. By elastically clamping the flange portion at the tip of the flanged stud 3 between the back surface of the cover 2, the exterior cover 2 can be easily and quickly attached to the main body frame 1 without any looseness or spoiling the aesthetic appearance. However, in order to remove the exterior cover 2 from the main body frame 1, it is sufficient to slide the exterior cover 2 upward relative to the main body frame 1, contrary to the above-mentioned installation process. The hook 5 of the cover 2 separates from the flanged stud 3 of the main body frame 1 and can be easily removed.

(Effects of the Invention) As explained above, when attaching the exterior cover, etc. according to the present invention, the backlash prevention device is placed at the appropriate position on the back surface of the exterior cover 2 corresponding to the flanged stud 3 provided on the main body frame 1. The exterior cover 2 for the main body frame 1 is made of a resilient material such as a plate spring having a tooth-shaped cross section and an inverted U-shaped mounting groove 4 at the bottom of the hook 5. can be quickly attached and detached by a simple operation such as sliding the exterior cover 2 vertically on the outer side of the main body frame 1 without using any tools, thereby significantly improving the efficiency of the operation. When the exterior cover 2 is attached to the main body frame 1, the hook 5 of the cover 2
is not only locked when the flanged stud 3 of the main body frame 1 is inserted into the mounting groove 4, but also the flange portion of the flanged stud 3 is held between the back surface of the cover 2 and the hook 50 by its elasticity. This prevents looseness when installing the exterior cover 2, and also allows the installation work of the cover 2 to be performed without using screws, thereby improving the aesthetic appearance of the outside of the machine itself. This has the effect of preventing damage to the environment.

Claims (1)

[Claims] In a device for attaching an exterior cover to the main body frame of a machine such as an electrophotographic copying machine, a stud with a flange is attached to a suitable position on the outside of the main body frame, and a stud with a flange of the main body frame is attached to a suitable position on the back side of the external cover. Then, by attaching an elastic hook such as a plate spring with a mounting groove such as an inverted U shape for locking to the stud, when the exterior cover is slid vertically close to the main body frame, the corresponding The flanged stud of the body frame moves in and out of the hook mounting groove of the cover, making it possible to attach and detach the cover without tools, and when the cover is installed, the flange portion of the flanged stud of the body frame moves into the exterior cover, etc. A device for preventing mounting looseness of an exterior cover, etc., characterized in that the elasticity of the hook presses against the back side of the cover to eliminate mounting looseness.
