Abstract

PURPOSE:To prevent a fixing device from being forced into the main body of a copying machine in a disengaged state, by providing an operation lever with a display device for indicating the disengaged state, when the first engaging lever and an engaging member are not engaged with each other. CONSTITUTION:A fixing device 15 fixed to the inside of the main body of a copying machine 1 by turning a swingable unit 17 clockwise, and pushing the device 15 along rails 21. If the first engaging lever 24 is not perfectly engaged with an engaging axle 27, the lever 24 turns a little clockwise about a support axle 23, a turning axle 25 also moves clockwise, and an operation lever 30 protrudes a little downstream. Therefore, the center lines 34a, 32a of an indicator 34 and a through hole 32 do not coincide with each other, an operator cannot confirm the presence of the indicator 34, and as a result, he pushed down the unit 17 again in order to complete engagement between the lever 24 and the axle 27.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a fixing device for a copying machine, which has one drawer attached to the main body of the copying machine and is divided into two units. . Conventionally, the fixing device can be freely pulled out from the main body of the copying machine, and the fixing device itself is divided into two units (for example, 54-1s, 54-1s, L,
The operation of pulling out the fixing device and closing it had to be performed separately for each operation, and this was done in view of the lack of quickness of operation.

Drawer position I: Stored, negative side C:
hinged on the other side ζ: at least 2 so that it can be opened and closed freely.
A support shaft is fixedly attached to the fixing device which is divided into S-C1 swinging units ζ, and a fixed unit ζ: which can freely engage with the fixed architrave is attached to this support shaft. A lever is attached to this retaining lever, and a spring is attached to the retaining lever for urging it in the engagement direction (t), and a rolling wheel is attached to the lever so that it can rotate freely, and the rotating shaft is attached to the main body of the copying machine. A second mooring lever that can be freely engaged with a portion thereof, and an operating lever for pulling out the fixing device are fixedly installed, and a spring is attached to bias the 182 movable lever in the engaging direction, I!, the actuation lever is provided with a display means that displays a non-engagement status SV when the Wi1 locking engagement member is not engaged with the engagement member. This is a fixing device for a copying machine.An embodiment of the present invention will be explained below based on Drawing I: Fig. 1 is a schematic configuration diagram of a copying machine in which a fixing device according to an embodiment of the present invention is housed, and Fig. 2 1 is a T perspective view showing the main part, and *S to 8 are operation explanatory diagrams sequentially explaining each operation of pulling out the fixing device, opening the swing unit, and then closing it.1

Corotron for transfer +51, corotron for separation +61, corotron for neutralization (7), cleaning device (8) and charging corotron (9). The paper feed cassette 1111m is equipped with a register roller 1111m on the downstream side of the paper feed cassette in which copy paper is stored.Furthermore, the paper feed cassette 1111m is equipped with a register roller 1111m on the downstream side of the cassette. A conveyor (Il) is provided for conveying the copy paper vtIl onto which has been transferred. Os is a short focus lens array provided at the top of the photoreceptor drum (3), and the original image illuminated by the exposure lamp a- is transferred to the photoreceptor drum (3). The image is formed on the side of the drum ■.

From this state 1, when the operator lifts the operating lever CWV in the direction of the arrow, the second holding lever (2) rotates in the summer needle direction C against the second firefly spring.

It comes out of the engagement hole (2) of the copying machine main body (1) and becomes a non-engaged state. Therefore, when the operator pulls the operating lever to the right in this state, the fixing device (Is) will move on the rail until it is stopped by the stopper (IJISS). It indicates the status of the

It becomes a released state. Figure 1147 shows this condition.

After storing the fixing device (a) inside the copying machine main body (1), rotate the swinging unit (671) clockwise, and then move the fixing device (a) along the rail (21) to the copying machine main body (1). This lI, the tips of the 1st moat lever @ and the 2nd moat lever ■ are sharp, so the 1st moat lever (2

The center of the support -c3v also moves clockwise, and the operating lever (11) is pushed out to the downstream side.Therefore, the center of the indicator shaft and the through hole (32m) do not match,
The operator cannot confirm the presence of the indicator through the through hole @, and the operator does not fully engage the indicator. Therefore.

8.If the operator pushes the swinging unit self-blade downward again,
The first mooring lever @ and the engagement @H'n are completely engaged.

As mentioned above, according to Act 1: The operator holds the operating lever and lifts it slightly. @Continue pulling while the fixing device moves. ■With the fixing device pulled out, 1!

One-touch "1'611" allows quick operations.

In addition, if the first locking lever and the engaging member are not fully engaged, the disengaged state is displayed by the indicator, so that the 11 copying machine main body (=
