的である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a means for supplying anti-offset liquid to an O-ler for constant toner wear in an electronic copying machine.
The purpose is to provide a liquid supply mechanism that is simple, does not require complicated adjustment of the supply amount, and at the same time has the ability to clean the rotating surface of the fixing roller.

。Electronic copying machines are generally equipped with a pair of heat rollers and pressure rollers that keep toner constant, but small amounts of toner remaining on the rotating surface of these fixing rollers can be In order to prevent transfer and contamination to new paper, it is necessary to supply an anti-offset liquid such as silicone oil to the fixing roller to reduce the affinity of its rotating surface for toner.

面に液を転移させることなどが行われている。As a practical matter, it is quite difficult to constantly and evenly supply the anti-offset liquid over the entire rotating surface of the fixing roller. The liquid is sucked up to the tip of the brush and the liquid is supplied by bringing the tip of the brush into contact with the rotating surface of the fixing roller, or by using a third roller that rotates in contact with the rotating surface of the fixing roller. , supply the liquid dropwise to this third O-lar, and
- The liquid is transferred to the rotating surface as evenly as possible by utilizing the smoothing properties of the roller.
しかしながら、上記したような従来の各手段によっても

題が充分に解決したとはいえない。However, even with the above-mentioned conventional means, it cannot be said that the problem regarding the supply of anti-offset liquid to the fixing roller has been sufficiently solved.

ある。これらの理由により、従来のオフセット防止液供
給装置の機構は非常に複雑かつ保守も煩雑であり、従っ
て生産コストも大きく、かつ故障も発生しやすかった。This is because, in order to prevent uneven supply due to changes in the amount of stored liquid caused by capillary action due to changes in the amount of stored liquid due to liquid consumption, a device for adjusting the wicking ability and amount of dripping is provided. Users often need to adjust the fluid supply,
In addition, in the case of using the third roller described above, unless the contact pressure of the roller is adjusted according to the swelling state of the third roller or the fixing roller due to the liquid, the liquid cannot be evenly supplied to the entire rotating surface of the fixing roller. It is from. For these reasons, the mechanism of the conventional anti-offset liquid supply device is extremely complicated and requires troublesome maintenance, resulting in high production costs and failures.

いる。In addition, to ensure the anti-offset effect, it is insufficient to simply supply the anti-offset liquid to the fixing roller, and the toner that adheres to and accumulates on the fixing roller despite the supply of the anti-offset liquid is not enough. I need to wipe it away. For this reason, it is necessary to install rotating surface cleaning devices such as cleaning blades, cleaning rollers, and cleaning webs that are mainly made of toner collecting materials such as sponges and felts in close proximity to the fixing roller.
This has added increasing complexity to the mechanics of electronic copiers.

By eliminating the need for a static cleaning device for the electronic copying machine, the mechanism of the electronic copying machine has been successfully simplified.Hereinafter, this invention will be explained with reference to the illustrated embodiments. That is,
1 to 3 show embodiments of offset prevention shield supply devices j and t according to the present invention, in which support shafts 3, 4 are provided on both end walls 1.2 of a hollow cylinder, A large number of small holes 6 are bored in the cylinder wall 5. The material for the hollow cylinder is most preferably metal for convenience of manufacture, but other materials may be used as long as they have high heat resistance. A large number of small holes are bored in the cylinder wall 5. At least one peripheral surface of the cylinder wall 5, that is,
The fiber layer 7 is tightly fixed only on the outer peripheral surface as shown in FIGS. 1 and 2, or over the entire area of both the inner and outer peripheral surfaces as shown in FIG. m Delamination 7 is nonwoven fabric;
Non-woven paper, artificial leather, Japanese paper, etc. are all suitable.
装置の筒内にはオフセット防止液１０を収容する。An anti-offset liquid 10 is contained in the cylinder of the device.

たは低く選定すべきである。In the example shown in FIG. 1, one of the support shafts 3 is provided with a through hole 9 with a palate 8, so that the cylindrical tube can be inserted through the through hole 9 and the palate 8 can be closed after injection. As will be described later, the prevention liquid can be consumed sufficiently for copying operations of tens of thousands of sheets. After drilling a hole and injecting the liquid through the hole, the hole may be closed with an appropriate sealant. The density of the fiber layer 7 must be such that the anti-offset liquid 10 does not pass through it under its own weight. It goes without saying that the term "not passing under the weight of the device" includes not only when the device is in use, but also when the device is at rest or stored. To give a numerical example, if the viscosity of the anti-offset liquid 10 is 30,000 c, s at room temperature, the density of the fiber layer 7 is 1.0 g.
/c+n3.500,000c, in the case of s-, Q, 2g/cm3
degree is optimal. Anti-offset liquid 10 at room temperature
If the viscosity of is lower or higher than the values listed above, the density of the l@R layer 7 should of course be chosen correspondingly higher or lower, respectively.

It is used in close contact with the heat 0-ra-12, or by using the FF in the heat 0-ra-11 as shown in FIG.
The appropriate viscosity of the cylinder to be accommodated is 30,000 to 60,000 C at room temperature for those placed in close contact with the pressure roller 12.
300,000 to 500,000 C.S at room temperature is appropriate for those brought into close contact with the heat roller 11. The reason why the viscosity for the heat roller 11 is high is that the viscosity decreases significantly due to heat received from the heater during operation. Below, two examples are listed.

設置や調節作業は全く不用である。*l Example 1 is for pressure rollers Example 2 is for heat rollers x 2 Adhesive to the outer peripheral surface of cylinder wall 5, thickness], 5 mm *3 Boria felt x 4 Polyester non-woven paper x 5 511 manufactured by Toshi Silicone Company -200 (Effects of the Invention) This invention is made as described above, and the cylinder wall 5 has a large number of small holes 6, but the offset prevention WIO is provided at least on the outer peripheral surface of the cylinder wall 5 under its own weight. Since the fiber layer 7 is tightly fixed so that it does not pass through, there is no risk that the anti-offset liquid contained in the cylinder will naturally leak out and contaminate various parts of the electronic copying machine. As the fixing roller rotates, this device installed in close proximity to it rotates, and the liquid subjected to the centrifugal force of the rotation wets the fiber layer 7 through the small holes 6, and at the same time, the liquid is wetted by the capillary action of the fiber layer 7. The liquid spreads evenly across the entire outer peripheral surface of the cylindrical wall 5, and therefore, the liquid is evenly applied over the entire rotating surface of the fixing roller that rotates closely to this device, thereby reducing the toner resistance of the rotating surface. Reduce affinity. The pressure of liquid supplied to the surface of the device is regulated by the rotation of the device and the centrifugal force applied to the molecules of the shield located on the inner peripheral surface of the cylinder M5 at a certain distance from the axis of the cylinder. is almost unrelated to the amount of liquid, so even if the liquid is consumed and reduced, the liquid will always be supplied at a constant rate at a constant rotational speed. Therefore, there is no need to install a regulating device or adjust the amount of liquid supplied as in the prior art.

るまでの複写枚数である。That is, the present invention has the feature that the offset prevention liquid can always be uniformly applied in the appropriate amount to the rotating surface of the fixing roller without adjusting the amount of supplied liquid. In addition to the ability to supply the anti-offset liquid, it also has the ability to statically clean the rotating surface of the fixing roller. In other words, in a fixing roller having a conventional anti-offset liquid supply means,
Despite the supply of liquid, residual accumulation of toner on the rotating surface was unavoidable, and as a countermeasure we had to install cleaning devices such as cleaning blades, cleaning rollers, and cleaning webs. Since the cylindrical surface of is made of jl1M117 made of non-woven paper, felt, Japanese paper, etc., the toner remaining on the fixing roller is immediately adsorbed and removed by this fiber layer, and the rotating surface of the fixing roller is Always kept clean. Such a cleaning ability is, for example, 20,000 sheets in the case of the above-mentioned Example 1, and 20,000 sheets in the case of the above-mentioned Example 2.
In the case of , even after copying 80,000 sheets, it remains almost unchanged from the initial state. In addition, the above 20000
The numbers 80,000 and 80,000 are the number of copies until the anti-offset liquid 10 once charged into the apparatus is consumed in each embodiment.

Since the mechanism of the electronic copying machine can be significantly simplified, it contributes significantly to improving the performance and economic efficiency of the electronic copying machine.
