DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer device applied to a transfer type electronic copying machine, and particularly to a transfer device suitable for use in a color copying machine.

従来カラー複写機では、感光体上に形成された粉像を転
写紙上に重畳形成するために、転写ローラーに転写紙を
巻きつけて3回乃至4回の転写を行なつていた。
In conventional color copying machines, in order to superimpose a powder image formed on a photoreceptor onto transfer paper, the transfer paper is wound around a transfer roller and transfer is performed three or four times.

この方法はいわゆるローラー転写法に基くもので、複数

This method is based on the so-called roller transfer method, and when transfer is performed multiple times, it becomes difficult for the next toner to be applied to the area where the previous toner image was located during the next transfer. A so-called hollow phenomenon occurs. Furthermore, when the transfer paper is charged and attracted to the roller, due to changes in the resistance of the transfer paper, it becomes difficult to wrap around the transfer roller when the humidity is high, and transfer failures tend to occur when the humidity is low. Therefore, the roller transfer method has many disadvantages in obtaining a final image of good quality with good color balance. There are also problems in the configuration and use of the device.

For example, in a copying machine that uses transfer paper of different paper sizes, if a small size transfer paper is used, the toner on the image drum will adhere to the area of the transfer roller where there is no paper, and then When using large-sized transfer paper, this area may cause stains on the back side or cause non-uniformity of the transfer electric field, causing uneven transfer. Therefore, cleaning means for the transfer roller is indispensable, and the operation of this cleaning means must be performed when there is no transfer paper, which is extremely troublesome.
An object of the present invention is to provide a transfer device that always performs good transfer when performing multiple transfers onto a transfer material.
Another object of the present invention is to provide a transfer device that enables separation or superimposed transfer of other images without disturbing the transferred image. The details of the present invention will be explained below using specific examples with reference to the drawings. FIG. 1 shows a side view of an embodiment of an electrophotographic machine using a transfer device according to the present invention. To explain its operation, the original on the platen glass 1 is integrated with the first scanning mirror 4. It is irradiated with the constructed illumination system (yaws lamp 3 and reflective shade 2), and the reflected light is scanned by the first scanning mirror 4 and the second scanning mirror 5. The first and second scanning mirrors scan the original while keeping the optical length of the first half of the lens system 6 constant by moving at a speed ratio of 2:1. The reflected light image above is from lens 6.
The light image is then color-separated by one of the filters 7a, Tb, and Tc corresponding to the three colors [red R) green G) blue B], and color separation is performed. The resulting optical image passes through the fixed third mirror 8 and fourth mirror 9, and further through the dustproof sealing glass 10, and forms an image on the photosensitive drum 11. The photosensitive drum 11 is rotatably supported on a shaft 11a, rotates in the direction of the arrow along with the printing operation, and is charged (for example, +) by the primary charger 12.
and then AC while irradiating the color-separated light image.
Alternatively, static electricity is removed using a static eliminator 13 having a polarity opposite to that of the primary one, and then the entire surface is exposed to light and uniformly irradiated with a lamp 14 to obtain a high-contrast electrostatic latent image. The electrostatic latent image on the photosensitive drum 11 is then visualized by a developing device 15. The developing units 15 are 15a, 1 for cyan C, magenta M, yellow Y, and black.
It is composed of four developing devices 5b, 15c, and 15d, and the developing device corresponding to the color separation filter 1 (for example, the yellow developing device 15c for the blue filter 7c) performs development. The transfer paper 16 in the force set is fed into the machine by a paper feed roller 17, first timed by a timing roll 18a, more accurate timing is taken by a timing roller 18b, and fed into the opening of a gripper 19. .

Then, the opening of the gripper 19 closes at the position where it is removed from the cam 20, and the leading edge of the transfer paper is gripped by the gripper 19. Next, while the transfer paper 16 passes between the transfer corona charger 21 and the photosensitive drum 11, the developed image on the photosensitive drum is transferred onto the transfer paper. For color copying, transfer material 1
The gripper 19 rotates three times while gripping the gripper 6, and after the three colors are transferred, the separation claw 22 and the gripper opening cam 23 operate.
The transfer material is released from the gripper 1 and transferred to the conveyor belt 24. After being transferred, the transfer paper is heat-fixed by a heat-fixing device 25 and then discharged. In this device, the transfer mechanism has various features to enable good transfer.

This conveyance guide is provided with a fixed upper guide plate 26a, and a lower lower guide plate 26b rotatable about a shaft 27a. When the solenoid SOL-1 is turned off, the lower guide plate 26b is moved in the T direction by its own weight. fall into. Specifically, the transfer paper 16, which is timed and fed by the timing roller 18b, is fed into the rig gripper 19 through the guide section. At this time, the transfer paper 16 is
For example, if the transfer paper is 40% faster than the gripper, it will move at a second speed faster than the moving speed of the gripper.
11 Length If you leave the gripper open, the transfer paper will be approximately 5m/
It is grasped by entering the inside of the body by about 100 m. At this time, the solenoid SOL-1 is turned off, and the lower guide 26b rotates by its own weight to the position shown by the chain line, so that the lower guide no longer applies resistance to the transfer paper.

Moreover, since the transfer paper is not held in the pinch guide 26 by opening the lower guide, wrinkles do not occur in the transfer paper. With the above configuration, wrinkles do not occur on the transfer paper, so there is no possibility of inconveniences such as omission of the transferred image during transfer or trouble with subsequent conveyance. In particular, it is extremely effective to increase the transport speed of the transfer paper and use the normal speed only during transfer, and the above configuration allows this to be carried out satisfactorily without causing any wrinkles in the transfer paper. Further, in the first illustrated example, a guide 27 and a tray 28 are provided adjacent to the position where the gripper grips the transfer paper.

Paper detection means, such as a lamp 29 and a light receiving element 30, are provided on the tray or on its path to detect the intrusion of transfer paper. To explain the operation of this constituent mechanism, the transfer paper sent by the second timing roller 18b normally gets into the gripper 19 whose mouth is open when the arm 19a of the gripper 19 rides on the cam 20. However, Grizpa 1
Even if the timing of the transfer paper 9 and the conveyed paper does not match and the transfer paper is not sandwiched between one gripper 19b and one gripper presser foot 19c, the timing roller 18b continues to rotate, so that the transfer paper continues to be fed. At this time, a guide 27 is disposed facing downward with respect to the leading edge of the transfer paper, and due to the synergistic effect of this guide 27 and the descent of the transfer paper due to its own weight, the leading edge of the transfer paper is sent downward by the guide 27 to the tray 28. will be stored in. If the storage of the transfer paper is detected by the detection means, and based on the detection signal, the operation of the jam detection control circuit, which normally detects paper feeding failure and stops the apparatus, is controlled so as not to stop the apparatus, the gripper can be fixed. If paper feeding fails, the device will not be stopped at all.
Enables subsequent paper feeding operation. Therefore, loss of copying time due to paper feeding failure is significantly reduced. Furthermore, since the transfer paper that has failed in feeding does not reach the photoreceptor, accidents such as the transfer paper damaging the photoreceptor surface can be avoided. Furthermore, the configuration of a part of the gripper of the transfer device will be explained.

The gripper part 19 that grips the transfer paper needs to pass between the photoreceptor 11 and the transfer corona charger 21, and in order to pass through this gap, the overall thickness can be made thin (for example, about 8 stages). required. Construction of the gripper under such conditions poses difficulties while requiring the following conditions. That is, each gripper requires sufficient pressing force to grip the transfer paper.

In particular, it is necessary to prevent paper slippage even during multiple transfers. However, if the base member of a part of the gripper is made thin, there is a risk that deformation may occur when the grip is released. In particular, if the base member of the gripper is thin and each gripper is independently pressed against the base member with a strong pressing force, the timing may not match when pushing up each gripper to release the gripper. , the platform itself may deform and follow the movement of the gripper, making it impossible to obtain a sufficient release gap.

In the example of FIG. 3, each gripper piece 1 is attached to the common shaft 19d.
9c is provided, and the transfer paper is gripped and released by one gripper piece at the same time by rotating and pressing the shaft. With this configuration, the grippers can be opened without fear of deforming the base member. On the other hand, in this configuration, the pressing force of each gripper may be uneven.

In this embodiment, an elastic movable structure using a spring or the like is provided on the table on which the gripper comes into contact, in order to equalize the pressing force. Specifically, as shown in the cross section shown in FIG.
It is provided on the stand 19b so as to be more elastically movable than f. When one piece of the gripper is closed, the transfer paper can always be held with an appropriate force by the gripping force determined by the elastic force of the spring 19f relative to the pressing force of the gripper. When the gripper 1 is released, the movable piece 19e pops out onto the stand 19b, so the transfer paper is lifted up from the gripper 22 and the separation claw 22
separation becomes easy.

This is a push-up member 32 having approximately the same structure as the gripper piece 31.
is provided on one gripper 33, and at the position where the transfer paper is gripped, only one piece of the gripper is released, but the push-up member 32 remains in close contact with the table. At this time, it is preferable to provide a notch in the surface of the table 33 to prevent the push-up member 32 from protruding. Therefore, the leading edge of the transfer paper is held on the table in such a manner that it also covers the push-up member, and is gripped by the grip. In addition,
In the illustrated example, each gripper piece 31 has a cam 34
The protrusion 34a is released by pushing up the cam 31. Therefore, in the gripping position, only one gripper piece has the cam projection 34a in the activated position, and one of the pushing member parts does not have the cam projection 34a. In the separation and release position, the cam protrusion 35a of not only the gripper piece but also the push-up member 32 is placed in the operating position, and when the gripper is released, the push-up member pushes up the edge of the transfer paper.

At this time, it is preferable that the amount of protrusion of the cam relative to the push-up member is smaller than the amount of protrusion of one piece of the gripper. Alternatively, the length of the height portion 32a of the push-up member 32 may be changed while the amount of cam protrusion is the same. With the above structure, the leading edge of the transfer paper is lifted well, and the separating claw is easily inserted under the leading edge of the transfer paper, allowing quick separation (FIG. 6).

上述把持機構により極めて良好な把持を可能とする。The above-mentioned gripping mechanism enables extremely good gripping.

In the illustrated example, while the pipe having the suction hole is rotated, the separating claws 22 are provided coaxially through a bearing material.
Can be operated independently. As described above, the separation claw 22 reaches the solid line position when the plunger SOL-2 operates for separation after transferring a predetermined color image onto the transfer paper. After the separation operation, the plunger SOL-2 is turned off and returned to the position shown by the broken line by the elastic force of the spring 37.
