Abstract

PURPOSE:To extract jam paper easily at the jam generation of transfer paper by rotating the jam paper around a rotation supporting point formed on one end of a rotary base board arranged on the opposite side to a photosensitive drum when observed from a transfer paper carrying course in a separating direction from the drum. CONSTITUTION:When jam is generated in transfer paper due to any reason, release in the arrow 23 direction is executed around the supporting shaft 22 of the rotary base board 21 by operating a proper release lever. As the result,a paper feed lower guide plate 20, a lower regist roller 3, a transfer lower guide plate 5, a transfer charger 6, a press wire 7, a separator roller 11, and a separation guide plate 15 which are embers arranged on the rotary base board 21 are simultaneously moved downwards to make the transfer paper 16 free. A turn belt 14 rotates around a turn belt supporting point 13 and does not interrupt the downward movement of the roller 11. At the time of jam paper removement, the transfer paper can be prevented from being broken because resistance does not almost exist at the pulling of the jam paper,and the jam treatment can be smoothly executed without the removal of the turn belt.

Description

DETAILED DESCRIPTION OF THE INVENTION 1491 The present invention relates to a transfer separation device that allows jammed paper to be easily disposed of when a jam occurs in a wet type copying machine.

Moxibustion End Skin 1 In conventional wet-type copying machines, U-turn transfer paper transport is the mainstream, and when handling jammed paper, the transfer paper may be torn or the turn belt may come off (the part of the turn belt that is holding the transfer paper in its mouth). However, depending on how the jammed paper is removed, the belt may come off), and mechanically, it is difficult to release the large transfer separation section.

SUMMARY OF THE INVENTION An object of the present invention is to provide a release mechanism for a transfer separation device in a wet type copying machine that can easily remove jammed paper when a transfer paper jam occurs.

1 litter The present invention will be explained below with reference to the drawings.

FIG. 1 is a side sectional view showing an embodiment of a transfer separation device according to the present invention, and FIG. 2 is a side sectional view showing the configuration of a conventional device.

Figure 2 shows the configuration of a conventional device.
Around the registration rollers 2.3. Transfer guide plate 4,
5, a transfer charger 6, a presser wire 7, a separation belt 1O supported by a separation belt hook 8.9, a separator roller 11, a turn belt that is rotatable about a turn belt fulcrum 13 by a turn belt release lever 12; 141 Separation guide plate 15 is provided, 1. Normal copy, transfer paper, 6. Yo1. Ji,,,O2u2. :3
L: Enter the photosensitive drum 1 surface while being regulated by the paper feed guide plate 4.5, place one edge of the transfer paper on the separation belt 10, and transfer the toner by the transfer charger 6 while being held down by the presser wire 7. After the image is transferred, it is guided between the separator roller 11 and the turn belt 14 by the separation belt IO, and is conveyed to the separation guide plate 15 side while being sandwiched between the separator roller 11 and the turn belt 14.

In such a device, when a jam occurs, the turn belt release lever 12 is rotated in the direction of arrow 17, the separation guide plate 15, etc. is rotated in the direction of arrow 18, and the jammed paper can be easily disposed of. However, when operating the turn belt release lever 12, it is difficult to completely avoid the turn belt 14 from the separator roller 11, so some contact remains, making it impossible to clear the jam smoothly and causing the turn belt to come off at one o'clock. occurs. Furthermore, releasing the separation guide plate 15 does not provide enough space for jam removal.

Furthermore, since the transfer charger 6 and the registration rollers 2.3 are not released, there is a large resistance when taking out the jammed paper, leading to tearing of the transfer paper 16.

The present invention aims to eliminate the above-mentioned drawbacks.
In accordance with the embodiment of the present invention shown in FIG. 1, the same parts will be described using the same reference numerals.

In FIG. 1, the transfer paper 6 is connected to the paper feed guide plate 19.20 and the registration roller 2.3, as in the case shown in FIG.
．． The toner image is transferred between the transfer charger 6 and the photosensitive drum 1 by the transfer guide plates 4 and 5, and the separator roller 11 is guided by the separation belt 10 supported by the presser wire 7 and the separation belt hook 8.9. and the turn belt 14, separated from the photosensitive drum 1,
The components that are transported to the separation guide plate 15 side are the members located outside of the transfer paper transport path when viewed from the photosensitive drum l, namely, the paper feed lower guide plate 20 and the lower registration roller. 3, lower transfer guide plate 5, transfer charger 6,
Presser wire 7, separator roller 11, separation guide plate 1
5 is mounted on a rotating base 21, and an arrow 23 moves away from the photoreceptor drum 1 using a rotating support shaft 22 provided at one end as a fulcrum.
It can be rotated in any direction.

Note that this rotation base 21 is equipped with a release mechanism to enable it to be locked at the solid line position and rotated to the imaginary line position, and prior to the rotation, the turn belt 14 is The belt is rotated about the belt fulcrum 13 in the direction of arrow 24 so as not to interfere with the movement of the separator roller 1.1.

Since the structure is as described above, if the transfer paper 16 jams for some reason, the arrow 23 with the support shaft 22 of the rotating base 21 as a fulcrum can be released by operating the appropriate release lever.
If the direction is released, it is a member provided on the rotation base 21. Paper feed lower guide plate 2 located under the transfer paper 16
0, lower registration roller 3, lower transfer guide plate 5, transfer charger 6, presser wire 7, separator roller 11,
The separation guide plate 15 moves downward together, and the transfer paper 16
Make it free.

Note that the member on the upper surface of the transfer paper 16 is fixed to a fixed member such as a machine frame, and does not move upward when the rotating base 21 is released. However, the turn belt 14 The separator roller 11 rotates around the rotation center so as not to impede the downward movement of the separator roller 11.

In this way, by releasing the lock of the rotating base 21 when a jam occurs, the transfer separation device can be divided into upper and lower parts with the transfer paper 16 as a border. Problems such as turn belt coming off can also be resolved.

Frog As explained above, according to the present invention, it is possible to completely separate the transfer separation device vertically, including the registration rollers, with the transfer paper transport path as the boundary, so that the jammed paper can be removed during the jammed paper removal process. Since there is almost no resistance to pull it out, the transfer paper will not be torn, and since the separator roller and turn belt are separated, the turn belt will not come off and jams can be cleared smoothly.
