Abstract

PURPOSE:To easily discharge transfer paper generating a trouble or to easily replace a transfer drum or the like by easily drawing out the transfer drum to a device body and allowing the transfer drum to be deformed to the outside of a frame body supporting the transfer drum. CONSTITUTION:At the time of replacing the transfer drum 5 or generating a jam, a handle 12 is rotated and a pin 13 is inserted into a front locking hole 14b. Consequently, the transfer drum 5 is supported so as to be separated from the periphery of a photosensitive drum. Even if the frame body 4 is drawn out from the device body 1 to the outside under said state, the photosensitive drum is not damaged. The pin 13 is drawn out from the locking hole 14b by rotating the handle 12 moreover and moved in a direction of an arrow shown by a short dashes line, the transfer drum 5 is inclined to one aperture 3 side so as to be deformed to the outside of the frame body and then drawn out in the arrow direction by a 1st rocking body or the like. Consequently, the transfer drum 5 can be easily drawn out through a notched part 11.

Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a transfer device, and more particularly to a transfer device that can be applied to devices that use a transfer drum as a transfer mechanism, such as copying machines, printers, and facsimiles. be.

(Prior art) ゛Conventionally, in a transfer device that has a transfer drum, when replacing the transfer drum or removing jammed paper, you have to insert your hand into the main body of the device to attach/detach the transfer drum and remove jammed paper, which requires maintenance. It was both difficult and dangerous. Furthermore, since a thin film is wrapped around the transfer drum, there is a problem that the film may be dented or damaged.

There are also devices that have a structure in which the transfer drum is attached to a frame and can be taken out along with the frame from the main body of the device, but in order to take out the transfer drum or jammed paper, you must remove screws from the frame. , there is a problem that the work is complicated.

(Objective) An object of the present invention is to solve the problems of the prior art described above and to provide a transfer device in which the transfer drum can be easily pulled out of the main body of the device.

(Structure) In order to achieve the above object, the present invention includes a frame body that is slidably provided on the main body of the device, and supports a transfer drum so as to be displaceable outside the frame body, and allows the transfer drum to be displaced on the frame body. The transfer drum is characterized in that an opening is formed so that the transfer drum can be taken out from the frame after the frame is pulled out from the device main body.

Hereinafter, a detailed explanation will be given based on one embodiment of the present invention.

FIG. 1 is a perspective view showing a transfer drum in an extended state in an embodiment of the present invention, FIG. 2 is a perspective view of a main part showing a displacement state of the transfer drum in the same embodiment, and FIG. 3 is a cross-section of an operating shaft. It is a diagram.

In Fig. 1, inside the device body 1 there is a guide tray) Lt2.
a."lb is provided, and this guide tray JLt'
A frame body 4 having openings 3 on both sides is slidably arranged in la and 2b. This frame body 4 is provided with a transfer drum 5 installed so as to face a known photosensitive drum (not shown). That is, a substantially rice scoop-shaped first swinging body 6 is fixed to one end of the transfer drum 5, and a hollow support shaft 8 extending from the other end of the transfer drum 5 introduces a power cord 7 into a predetermined portion of the transfer drum 5. The second #a! is attached to this hollow support shaft 8! The moving body 9 is fixed.

The first rocking body 6 and the second ta! The lower end of the moving body 9 is slidably supported by the operating shaft IO. One end 10a of this operating shaft 10 is rotatably supported by one side wall 4a of the frame 4, and the other end 10b of the operating shaft 10 is externally connected to the other side wall 4b of the frame 4 through a notch 11. A bearing 1 extends and further fixes a portion of the operating shaft 10 near the first rocking body 6 to the frame body 4.
It is supported by 2. Further, the cross-sectional shape of the first oscillating body 6 portion of the operating shaft 10 is approximately P-shaped, as shown in FIG. The first swinging body 6 is configured to be able to slide laterally relative to the moving body 9 and not rotate relative to the operating shaft 10.

The notch 11 of the frame 4 through which the other end 10b of the operating shaft 10 extends has an opening area large enough for the fulcrum 6a at the lower end of the first rocking body 6 to pass through. Also, the other end 1
A handle 12 is provided on 0b so as to be slidable in the axial direction of the operating shaft 10 similarly to the first swinging body 6, and to be engaged in the radial direction of the operating shaft 10.

A pin 13 with a knob is slidably provided on the guide cylinder portion 12a provided at the upper end of the handle 12, and the tip of the pin 13 is bored through the other side wall 4b of the frame 4 at a distance. It is possible to engage and detach from the locking holes 14a and 14b.

Next, the operation of the embodiment configured as described above will be explained.

When the frame 4 and the transfer drum 5 are arranged in the device body 1, the pin 13 is inserted into the locking hole 14a on the back side in FIG. 1, and in this state, the transfer drum 5 is attached to the frame. 4, and is in contact with the circumferential surface of a photoreceptor drum (not shown).

When replacing the transfer drum 5 or when a jam occurs, the handle 12 is rotated to insert the pin 13 into the locking hole 14b on the front side in FIG. Then, the transfer drum 5 is supported apart from the circumferential surface of the photoreceptor drum. Therefore, even if the frame 4 is pulled out from the device main body 1 in this state, the photosensitive drum will not be damaged.

As mentioned above, the frame 4 is connected from the device main body 1 to the guide rail 2a.
, 2b and the state shown in FIG. 1 is the state shown in FIG. In this state, the transfer paper wrapped around the transfer drum 5 can be easily removed or the jammed paper can be taken out.

Further, the handle 12 is further rotated to pull it out from the locking hole 14b, and the pin 13 is moved in the direction of the broken line arrow, so that the transfer drum 5 is moved to the outside of the frame 4 as shown in FIG. The transfer drum 5 can be easily pulled out from the frame 4 through the notch 11 by tilting it toward the opening 3 and pulling out the transfer drum 5 together with the first rocking body 6 and the like in the direction of the arrow in FIG.

(Effects) As explained above, in the present invention, the transfer drum can be easily pulled out into the main body of the device, and the transfer drum can also be displaced outside the frame supporting the transfer drum, so that troublesome transfer paper can be removed. Alternatively, it is possible to provide a transfer device in which the transfer drum can be easily replaced, and damage to the transfer drum and danger to the operator when replacing the transfer drum can be eliminated.
