Description

[Detailed description of the invention] This invention develops an electrostatic latent image or a magnetic latent image formed on a recording device, especially a latent image carrier, with toner, and transfers the developed image to a transfer sheet to record the image. This invention relates to a recording device for obtaining objects.

As such recording devices, electrophotographic devices, facsimiles, and the like are known. These are generally equipped with a cleaning device to remove toner remaining on the latent image carrier after transfer, and the cleaning device is equipped with an air suction blower to collect the removed toner. are doing. For example, when manufacturing a large electrophotographic device, if a blower is attached to the device body, the vibrations of the blower will be transmitted to the device body, disturbing the copied image. Image disturbance caused by such vibration is generally called jitter.

The purpose of this invention is to provide a recording device that prevents the occurrence of jitter due to the vibration of the blower.

This invention is characterized in that the blower is constructed separately from the main body of the device, and the two are connected by a vibration absorbing means.

FIG. 1 schematically shows the main parts of the recording apparatus according to this invention. The device main body 1 includes a base plate 2.
A connecting stay 4 extending from the blower device 3 is attached with a bolt 6 via a vibration isolator 5.
The blower device 3 includes a filter 7 and a blower 8, and the filter 7 is connected to a fur brush cleaning device 10 disposed at a specific position around the latent image carrier drum 9 in the device main body 1 through a duct 11. It is connected. After the transfer, the toner remaining on the surface of the latent image carrier drum 9 is removed by the rotating brush 10a of the cleaning device 10, and the removed toner enters the filter 7 of the blower device 3 through the duct 11. It will be collected here.

In this invention, the device main body and the blower device are connected by vibration absorbing means. In the embodiment shown in FIG. 1, the vibration absorbing means is constituted by a connecting stay 4, two vibration isolators 5 and bolts 6 that sandwich the connecting stay 4. The vibration prevention means can be composed of only the stay 4 and the bolt 6, as shown in FIG. Vibrations from the blower device are absorbed by the gap between the bolt 6 and the mounting hole 4a of the stay 4, which has a diameter larger than the diameter of the bolt 6, and are not transmitted to the base plate 2 of the main device. The vibration prevention means also includes a mounting hole 4a of the stay 4 and a bolt 6, as shown in FIG.
A single rubber pusher 12 may be interposed between the two.

FIG. 4 shows one specific example of this invention. The same members as in the above embodiment are given the same reference numerals. The device main body 1 has a lower opening 1a.
has a base plate 2 therein, and a blower device 3
is equipped with a filter 7 and a blower 8. The device main body 1 and the filter 7 are connected by a detachable duct 11, and another duct 13 is detachably attached to the filter 7. This other duct 13 is connected to the blower device 3
, not as a blower device attached to the cleaning device of the device main body, but independently from the device main body.
It is used when used alone as a cleaner, and switching between the two is performed by the lever 7a of the filter 7. Blower device 3
The power plug 14 is connected to the device main body when the blower device is used for the device main body,
When used alone, it can also be connected to a regular outlet. Both the device main body 1 and the blower device 3 have casters 15 and 1 on their lower surfaces.
The blower device 3 is pushed into the lower opening 1a of the main device 1, and is attached to the base plate 2 of the main device via the stay 4 as shown in FIG. Attached via swing material.

As described above, according to this invention, since the device main body and the blower device are connected by the vibration absorbing means, vibrations of the blower device are not transmitted to the device main body, and no jitter occurs in the recorded image. Further, it would be even more convenient if the blower device and the main device were detachably connected by means of vibration absorbing means so that the blower device could be used independently as a cleaner.
