Abstract

PURPOSE:To prevent the contamination with toner and to facilitate assembly, inspection, maintenance, etc. by coupling a photoreceptor, a developing device, a cleaning device, a reducing device and a toner replenishing part into one body, and mounting the assembly drawably to a movable mounting frame. CONSTITUTION:A photoreceptor 1 via bearings, a developing device 2 provided with a magnetic brush 2a, and a cleaning device 3 provided with a scraper blade 3a are mounted to the front and rear side plates of a movable mounting frame 6 in respective casings, and a reducing device 4 provided with a conveying screw 4a, a reducing screw 4b and a distributing screw 4c as well as a toner replenishing part 5 coupled in one body thereto are mounted with the device 3 and the device 2 in the above-mentioned way. The casing in the part of the screw 4b is mounted to the side plate on one side of the frame 6. Thus all the devices from the photoreceptor 1 up to the part 5 are mounted in the frame 6 by maintaining mutual operating relations.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses powdered toner and processes 1141. The residual toner is sequentially returned to the developing device and used;! -)'+ttRegarding improvements in photographic recording devices.

Conventionally, in the electronic photo recording device described in -11,
The photoreceptor, developing device, cleaning device, and recovered toner reducing device are drawn out in pairs 1-7 in the main body of the recording device so that assembly, inspection, maintenance, etc. can be easily carried out. It is known that a unit can be formed with rV-1<J in a possible frame.

However, in the electrophotographic recording apparatus, the toner replenishment unit that supplies replenishing toner to the developing device was attached to the recording apparatus main body, so when the photoreceptor etc. were attached, when the frame was pulled out, the toner supply unit Toner leaks and stains occur between the feeding section and the lending device or the developing device. , It's Do, Tori A, draw out the 1-digit slot, and draw ■.

When installing the frame, there is a problem in that it takes time and effort to remove and reinstall the connecting parts.

The present invention has been made in order to provide an electrophotographic recording device that requires only a small number of components, solves the above-mentioned problems, and can be easily assembled and maintained. 7 of the 4 inventions is a child photographic recording device,
A photoconductor, a developing device using powder toner, a cleaning device that removes residual toner from the photoconductor, a reducing device that returns the removed toner from the cleaning device to the developing device, and replenishing the reducing path of the reducing device d. For an electrophotographic recording apparatus equipped with a toner replenishing section that supplies toner, the photoreceptor, a cleaning device such as a developing device 1σ, and an 'I'
A feature is that the Jd source/device and the toner 1vlt supply section are integrally drawn out from the main body of the recording apparatus, and the movable mounting is attached to the frame.

Hereinafter, the present invention will be explained in detail based on illustrated examples.

FIG. 1 is a partial oblique view of a photographic recording device according to the present invention, FIG. 2 is a view from the 1E side, and FIG. 3 is a side view of the toner introduction section seen from the right side.

Are you talented at drawings? / is a photoreceptor, 2 is a magnetic brush, 2a is f
+iif powder toner developing device 3, a scrubber plate 3 for removing residual toner from the photoconductor;
The cleaning device (K13) is a cleaning device that removes the toner scraped off in the cleaning device (K13).
The cleaning device internal transport screw tla transports the tonneau to the front of the figure and carries it out of the cleaning device 3; ) A reducing device equipped with a distribution screw C that feeds into the developing device λ, and a reducing device having a distributing screw C that feeds the toner into the developing device L along with the toner from the cleaning device 3 The toner replenishing unit for replenishing the toner is a movable frame that is retractably engaged with the main body of the recording device by means of a linear bearing 7.

Then, everything from the photoreceptor to the toner replenishment section to the S dimension maintains their working relationship with each other. II+
It is attached to +1vN frame B. In other words, the photoreceptor is mounted via bearings, the developing device 4.7:17 and the cleaning device 3 are movably mounted to their casings, and movable mountings are attached to the front and rear side plates A and A of the frame B. , and the reducing device l and the toner replenishing section j physically coupled thereto are connected to the cleaning device 1t3 and the developing device λ.
The movable mounting of the casing is on one side of the frame. (Due to being attached to the fil board at h, the -C1 movable attachment is attached to frame O.

(/I-) Therefore, at least the assembly 9 inspection, maintenance, etc. from the photoconductor/toner replenishment section s 4, the movable mounting with the recording device pulled out from the main body is J', <, LTh. Therefore, these operations can be performed extremely efficiently, and unlike conventional recording devices, the rIT operation is
llV is a drawer with a frame B, [(y) removal and installation is not broken, movable mounting is a drawer with a frame B [2-type fj
Since the relative operating relationship from the photoconductor to the toner introduction section j is maintained completely even in the case of tf, there is no risk of toner contamination.
