Abstract

PURPOSE:To facilitate the work at the time of the occurrence of the jam by opening and closing the bottom part of the main body of the recording device and releasing the transferring pole, the conveying device, etc., provided at the bottom part by pushing up the main body. CONSTITUTION:In a main body 1, a photosensitive drum 7 is provided, the paper is sent from a cassette 3 to a photosensitive drum 7 by rollers 12 and 13, and transferred by a transferring pole 9. Next, the paper is sent to a stabilized roller 14 by a conveying device 15 and discharged to a tray 4. At such a time, when the jam of the paper occurs, by using a sash lift part 22 at this side of the main body 1, the main body 1 is lifted up, and then, the body is inclined with the shaft provided at the depth side as the supporting point and a bottom part 20 is released. By interlocking to lift up the main body, a leg part 21b is protruded and the inclination of the main body is supported. The bottom part 20 is released, and the jam to occur at the transferring pole 9, the conveying device 15, etc., is removed. Consequently, since the bottom part of the main body is released, the jam can be easily removed.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a recording device, and in particular, an object of the present invention is to provide a recording device whose interior can be easily opened when a paper jam or the like occurs inside the recording device. shall be.

[Prior art]

In general, recording devices such as electrophotographic copying machines are designed to eject an image after recording an image on the paper being fed, and if a paper jam occurs during feeding, a so-called jam occurs. is designed to open the inside of the main body and remove jammed paper.

Among those that open the inside of the main body, there are clamshell types that divide the main body into upper and lower halves, and jams that occur when the fixing unit, paper feed unit, etc. move in parallel in the direction away from the photoreceptor drum, which is the image carrier. There is a product named Chatre Sox 850 (manufactured by Sanyo Electric Co., Ltd.) that secures space for removing paper, but the clamshell type has a large number of parts and requires a lot of assembly time. Therefore, the overall cost is high, and like the clamshell type, the number of parts is large compared to the Shadlex type 2, and the number of assembly steps is large, making adjustments difficult. In addition to the problem that the overall cost is high due to the complexity, there is also the problem of poor workability.

(Purpose of the Invention) This invention solves the problems of the conventional products as described above, and reduces the number of parts to lower costs, secure sufficient work space, and It is an object of the present invention to provide a recording device that can be made compact as a whole.

(Structure of the Invention) The present invention provides a recording device that has a conveyance section and records an image while conveying a recording paper with the conveyance section, in which the bottom of the main body of the recording device can be opened. It has a structure.

(Embodiments of the invention) Embodiments of the invention shown in the drawings will be described below.

1 and 2 show a recording apparatus according to the present invention, in which a document mounting table and a platen cover 2 are provided on the upper surface of a main body 1, and a paper feed cassette 3 is provided on one side of the main body 1.
is removably arranged, and a discharge tray 4 is provided on the other side.

A photoreceptor drum 5 serving as an image carrier is provided inside the main body 1, and a charging device 6 is provided in the upper vicinity of the photoreceptor drum 5 to face it.
An exposure section 7, a developing device 8, a transfer pole 9, a separation pole 1O, and a cleaning device 11 are arranged in order at the front of the photoconductor drum 5 in the rotational direction so as to approach the photoconductor drum 5 and face them. There is.

Further, a paper feed roller 12 is provided at the top of the paper feed cassette 3, and the paper feed roller 12 makes contact with the top surface of the uppermost sheet of paper in the paper feed cassette 3 and sequentially feeds out the paper. is conveyed to a position between the transfer pole 9 and the photosensitive drum 5 via a pair of upper and lower registration rollers 13;
Further, a general feed washer 15 is provided between the separation electrode 10 and the fixing device 14, and a pair of upper and lower ejection rollers 16 are provided on the ejection tray 4 side of the fixing device 14.

On the other hand, in the lower part of the main body 1, both sides 1a of the main body 1
, 1b is pivotally supported 30 between the bottom part 20 and the rear side part of the main body 1, so that the inside of the main body 1 can be opened.

In addition, the both side parts 1a, lb have leg members 21a, 21 which can be retracted from the lower part of the front side thereof, as shown in FIG. 4.5.6.
b are arranged respectively.

The transfer pole 9, separation pole 10, conveyance device 15, etc. are arranged on the bottom 20 of the main body 1.

Next, the operation of the above will be explained.

First, the uppermost sheet of paper in the paper feed cassette 3 is conveyed by the paper feed roller 12 and reaches a pair of upper and lower registration rollers 13, where it is re-fed at a predetermined timing and transferred to the photoreceptor drum 5 and the transfer pole. It reaches between 9 and 9.

On the other hand, by this point, a toner image corresponding to the original image has been formed on the photoreceptor drum 5 by the developing device 8 and the like, and since the toner image is at a position corresponding to the conveyed paper, the transfer pole 9 transferred to the separation pole 10
After being separated, the paper is generally sent to the fixing device 14 by the conveyance device 15, and after being fixed there, it is discharged to the discharge tray 4 provided on the other side of the main body 1 by a pair of upper and lower discharge rollers 16. It has become.

During such operation, paper jams may occur inside the main body 1.
When a so-called jam occurs, first, as shown in FIG. 3, an operator lifts the main body upward using the hand grip 22 on the front side of the main body l.

If you lift the front side of main body 1 upward in this way,
is tilted with the front side thereof as a fulcrum, but in conjunction with this lifting operation, the leg members 21a and 21b provided on the front side of the bottom surface of both sides 1a and Therefore, the main body 1
Even if the front side is released, the state shown in FIGS. 4 to 6 will be maintained.

After that, if the front side of the bottom part 20 is pressed downward, the bottom part 20 will swing downward because the main body 1 and the bottom part 20 are pivoted 30 with the back side as a fulcrum as described above. This will open up the inside of the main body 1.

When the internal jam removal is completed in this way, the handle portion 22 of the main body l is used to lift the body l slightly upwards, and then the leg members 21a and 21b are moved to the side portions 1a and 21b.
The work is completed by retracting the main body 1 into the horizontal position.

In the above embodiment, the leg members 21a and 21b are manually protruded downward, but the present invention is not limited to this, and when the main body 1 is swung upward, the leg members 21a and 21b are automatically protruded downward.
, 21b may be configured to protrude, and the bottom portion 20 may be configured so that the main body 1 is lifted and the bottom portion 20 swings downward by natural fall to open the inside of the main body 1. Alternatively, the bottom portion 20 may be manually opened. Either may be used to open the interior of the main body 1 by swinging it downward by releasing the lock or the like.

〔Effect of the invention〕

By configuring this invention as described above, the number of parts is small (therefore, the cost is low), and the interior can be opened very easily. Since it can be done by motion, it has the advantage of being ideal for small-sized recording devices.

Compared to the two-part method currently in practical use,
The number of open parts in the copying machine body is minimal, and it is safe because you do not have to touch the power supply or charging parts installed inside the copying machine. Furthermore, since the conveyance part has a large degree of openness, it is easy to prevent jams from occurring. It also has effects such as extremely good workability.
