JPS58193574A - Destaticization lamp of electrophotographic copying machine - Google Patents

Abstract

PURPOSE:To confirm the light emitting state of a destaticization lamp only by opening a cover, and to shorten an operation time by allowing light transmitted through a light transmitting means provided to the holder for the destaticization lamp to pass through even the opening of a main frame. CONSTITUTION:A rubber grip 4 fitted to one end of the destaticization lamp serves the holder for attaching and detaching the destaticization lamp to and from a power source part. The opening 5 provided to the rubber grip 4 of destaticization lamps 6 and 7 arranged adjacently to a photoreceptor 8 is on the side of the openings 12 and 13 of the main frame 11 of a copying machine. Since the inside of a tube is seen through the opening 5, its transmitted light is detected to confirm the light emitting state of the destaticization lamp and the front cover 14 is only opened to check fault of the destaticization lamps 6 and 7 easily.

Description

[Detailed description of the invention] Kll
This article relates to a static electricity removal lamp.

Electrophotographic copying machines have a transfer mechanism to promote transfer.
Static charge removal run or cleaning of the burial mound! According to fK, a pre-charging treatment static elimination lamp is used to remove the electrostatic latent gII that remains for 4 hours after toner removal. These static elimination runs fl
-1. Both of the photoconductors are arranged with Kliil, and the Il area is surrounded by a reflector, and furthermore, both longitudinal ends are supported by the main frame or electric part, so the copying machine Once the front cover tube was opened, it was impossible or extremely difficult to check the luminous S tube from the outside. Therefore, the general method for ensuring the luminous state of the static elimination rung is to remove the photoreceptor from outside the TII military aircraft, which requires a lot of time and effort.

The present invention has been made to eliminate the above-mentioned drawback 1 of the conventional technology, and its purpose is to eliminate the luminous state ii of the static elimination rung by simply opening the front cover f without removing the photoconductor 1-* from the military aircraft. The purpose of K is to shorten the work time so that the value can be determined with certainty.

In order to achieve this purpose, the present invention provides a static eliminator for a photocopying machine, which has a cap part for connecting to the 11 barrier part at one end and a holding part at the other end. By providing a means for transmitting the light of the rung and providing an opening in the main frame of the electrophotographic copying machine,
In the zero-irradiation static eliminator Lande, which is characterized in that the light transmitted through the light transmitting means can be detected from the outside through the opening, the holder Vi, for example #
It is a rubber grip fitted to one end of the electric tube, and the spinneret fitting is a screw-in type, and the connection and disconnection between the static elimination lamp and the electrode is performed by rotating this rubber grip tube. . Further, the light transmitting means provided on the first front holder may be a sekiguchi, or the holder may be made of a transparent body. 1 more light transmission hand R
Fi can be provided not only at one end of the turtle removal lamp but also at both ends.

need to be provided in other parts of the group.

As described above, according to the present invention, the front force of the seal machine, etc.
Just by opening the tube, you can easily detect the luminescence status of the static elimination lamp, reducing work time.

Embodiments of the present invention will be described below with reference to the drawings.
4 is shown. This division 1 run f is derived from a glass tube 1 of the circle III type, and a tungsten lamp 2 (fuse tube) is arranged in series within this glass tube 1. A screw-in cap 3 is attached to one end of the glass tube l, and is connected to a screw cap 3 (not shown) via a screw cap 3. The other end KFi of the glass tube 1 is fitted with a rubber grit 'f4. This rubber grip 4 serves as a holder when attaching/detaching the static elimination lamp tube to the turtle part. Insert it into the designated place, turn the f4 to the right and screw in the cap part 3. Conversely, when removing, use the KFi rubber grip 4.
1- Rotate to the left. The rubber grip 4 is formed with an opening 5 as shown, and the inside of the glass tube can be seen through this opening 51'' (see left side view in Fig. 1S), that is, the IS-lamp When the light is emitted, the leaked light is transmitted in the axial direction inside the Galanu tube and the opening 5tAL,
leaked to the outside.

The m2 diagram is #! The static elimination lamp shown in Figure 1^ is incorporated into the copy 11, and is incorporated as a charging pre-treatment static elimination run f6 and a transfer pre-treatment theory 1 run shift. These static elimination lamps6.
Each of the V-rams 7 has an elongated shape extending in the axial direction of the photoreceptor V-ram 8, and is adjacent to the surface of the photoreceptor V-ram 8. Furthermore, these static elimination run f6.7ilt reflector plate 9,
It is surrounded by lO. Reference number lid is the main frame for attaching various devices that make up the copying machine tube, and this main frame 11KF'i is the opening 12.13 for checking the failure of the static elimination lamp, i.e., establishing the luminous U tube.
is popular. Note that the static elimination lamp 6.7 is arranged so that the opening 5 provided in the rubber grip 4 is located at the opening 12, 13 of the upper main frame. If the static elimination lamp 6.7 is arranged in this way, the static elimination lamp 6.7 can be illuminated just by opening the front cover 14 of the copying machine, as shown in FIG. In addition, in Fig. 5, the rubber grip 4 of the static eliminator 6.7 is located further away than the main frame 11, but this is intended to facilitate the addition and removal of the III, and is not necessarily necessary. In addition, the light transmission opening 5 provided in the rubber grip 4 and the openings 12 and 13 in the main frame 11 only need to be able to see the light of the static elimination rung, and their shapes and sizes do not overlap so much.

As described above, in the present invention, an opening is provided in the stone K11l holder through which light passes through from the end of the static eliminating run, and an opening is provided in the main frame of the copying machine so that the far-off light can be detected. Therefore, the static eliminator rung can be checked for failure simply by opening the front cover, reducing work time.
