Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a platen glass fixing device for a copying machine.

(Prior Art) Conventionally, in the frame of the copying machine, the four edges of the platen glass are placed on the upper frame via a buffer strip. However, the cut surface of this platen glass is directly brought into contact with a rising member made by sheet-metal working the upper frame, or a vertical wall surface provided in steps so as to regulate the movement in the horizontal direction.

(Problems to be solved by the invention) Therefore, in such a copying machine, the vertical vibrations and shocks generated at the time of transfer can be absorbed by the buffer bands, but the horizontal vibrations and shocks can be absorbed. Since there was nothing to absorb, the cut surface of the platen glass collided with the rising member, the vertical wall surface, etc., and there was a drawback that the platen glass was damaged by the impact.

(Means and Actions for Solving Problems) The present invention has been made in order to eliminate the above-mentioned drawbacks, and is a rising member provided on the upper frame of a copying machine to regulate the horizontal movement of the platen glass. A cushioning member is attached to the outer periphery of the platen glass, and the cut surface of the platen glass is fixed to the rising member through the cushioning member so that the platen glass is not damaged by the horizontal vibration or shock generated when the copying machine is transported. The present invention relates to a platen glass fixing device for a copying machine which is prevented.

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

FIG. 1 is a partially cutaway perspective view showing an embodiment of a platen glass fixing device for a copying machine according to the present invention.

Among the upper frames 1 on the four sides of the copying machine, the upper and lower frames 1 on the front and rear sides are subjected to sheet metal working to provide rising members 2 having a constant width. When the platen glass 3 is placed on the upper frame 1, the rising member 2 abuts the cut surface of the glass 3 to regulate the movement in the horizontal direction. Therefore, the position of the rising member is a position where the front and rear sides of the platen glass 3 can be stably fixed.

A cushioning member 4 is attached to the outer periphery of the rising member 2. The cushioning member 4 is made of rubber or plastic,
As shown in FIG. 2, a vertical groove 5 for attaching to the rising member 2 is provided at the central portion, and a taper 6 is provided at the head portion.
When the platen glass 3 is mounted on the upper frame 1, the taper 6 is provided for facilitating the cutting surfaces on the front and rear sides of the platen glass 3 to slide from the cushioning member 4 to the front of the rising member 2, and therefore the inclined surface thereof. Is high on the outside and low on the inside.

In the case where the cushioning member 4 is made of a hard resin such as plastic as another embodiment of the cushioning member 4, as shown in FIG. The claw 7 and the like are provided on the above. As a result, when the cushioning member 4 is attached to the rising member 2, elasticity in the horizontal direction can be obtained.

The present invention is configured as described above. Next, fixing of the platen glass by this device will be described.

As shown in FIG. 1, a cushioning member 4 is provided on the outer circumference of a rising member 2 provided on the upper frame 1 on the front and rear sides of the copying machine.
Install. Next, a buffer strip 8 is laid on the upper frame 1. The cushioning band 8 may be laid just in front of the cushioning members 4 of the front and rear side upper frames 1 provided with the rising members 2, but for completeness, it is also provided on the left and right upper frames 1. Lay. After that, the edges of the four sides of the platen glass 3 are placed on these buffer bands 8. The method is to place the cutting surfaces of the front and rear sides of the platen glass 3 on the head of the cushioning member 4 attached to the rising member 2, and then press the glass 3 up or down. In this way, the cutting surfaces on the front and rear sides of the platen glass 3 descend along the taper 6 of the head of the cushioning member 4, and when the lower surface thereof reaches the cushioning zone 8, the cushioning member 4 is cut off. It is automatically and elastically fixed by the inner side, and horizontal movement in this direction is restricted.

Next, a registration guide 9 is brought into contact with the left end side of the platen glass 3, and both end edges of the registration guide 9 are fixed onto the upper frame 1 with screws 10 or the like. Further, a holding plate 11 provided in a step shape on the upper surface and the cut surface of the platen glass 3 on the right end side.
Then, both ends of the pressing plate 11 are fixed to the upper frame 1 with screws 12.

According to the present invention, the platen glass 3 is fixed on the upper frame 1 of the copying machine as described above. However, the cushioning member 4 is made of rubber and, for example, as shown in FIG. If a plate-shaped projecting portion 13 integrated therewith is provided in advance, the buffer band 8 laid on the upper frame 1
Becomes unnecessary.

Further, the rising member 2 may be formed separately from the upper frame 1, and the rising member 2 may be attached to the inner edge of the upper frame 1 by fitting it into, for example, a notch groove formed in a key shape. Needless to say.

(Effect of the Invention) Since the present invention is configured as described above, there is an effect that the damage of the platen glass can be almost completely eliminated when the copying machine is transported. Further, when the platen glass is fixed on the upper frame of the copying machine, there is a double effect that the front side and the rear side of the glass can be attached very easily and quickly.
