Description

  The present invention relates to a sheet-like or film-like thin heating element, various transport rotary rolls equipped with the heating element, various parts of various office equipment such as a copying machine and a printer equipped with the heating element.

  A heater wire is a major conventional heating element. Various rotating rolls such as a conveyance roll, a fixing roll, a pressure roll, and a photosensitive roll of a copying machine may become unclear when the surface comes into contact with the paper that comes into contact with the surface, so that printing or printing is blurred. In order to prevent condensation, a conventional rotating roll has a heater wire embedded in the rotating roll so that the roll can be heated by heat generated by the heater wire.

The conventional rotating roll has the following problems.
(1) Since the heater wire consumes a large amount of power, the running cost increases if the heater wire is constantly heated. For this reason, normally, when not in use, the apparatus is kept in a standby state with low power consumption, and the power is turned on during use to generate heat. In this case, it takes time to warm up until it can be used, and the waiting time until the work starts becomes long, so that workability is poor.
(2) Since the heater wire is linear, it is difficult to keep the temperature of the entire roll uniform unless it is arranged on the entire roll. If it is closely arranged on the entire roll, the power consumption increases and the running cost increases. In addition, the roll becomes larger, heavier, and costs are increased.

  The present invention provides a heating element that consumes less power, has a short warm-up time from when the power is turned on until it reaches a predetermined temperature, easily heats the entire roll surface uniformly, and generates ions efficiently due to heat generation, and its heat generation The object is to provide rotating rolls and various office equipment components that can be heated by the body.

  The sheet-like heating element of the present invention, as described in claim 1, is mainly composed of an oxide compound of tin (Sn) and lead (Pb), and the heating material that generates heat by supplying power is sheet-like (film-like, tape-like, In a sheet-like heating element provided on a substrate (including a belt-like shape), an ion generating material or an ion generating material and a far-infrared generating material are provided on the surface of the heating material. As claimed in claim 2, a heat generating material which is mainly composed of an oxide compound of tin (Sn) and lead (Pb) and generates heat by supplying power is provided on a sheet-like substrate, and the surface of the heat generating material is sheet-like. In the sheet-like heating element covered with the protective material, the surface of the heat generating material or the outer surface of the protective material may be provided with an ion generating material or an ion generating material and a far infrared ray generating material. The sheet-like heating element according to claim 3, wherein the ion generating material is a metal and the far-infrared generating material is ceramic, and the heating material or the protective material is a foil, nonwoven fabric, thin film, powder, film, or sheet. It can be laminated on the surface. According to the fourth aspect of the present invention, in the sheet-like heating element, the heat generation power source can be electricity generated from the solar power generation device.

  As described in claim 5, the rotating roll of the present invention is mainly composed of an oxide compound of tin (Sn) and lead (Pb), and a heating material that generates heat by supplying power is provided on the inside or the outer surface of the rotating roll. An ion generating material or an ion generating material and a far infrared generating material are provided on the surface of the heat generating material. According to the sixth aspect of the present invention, the sheet-like heating element may be provided on the inside or the outer surface of the rotary roll.

  According to the seventh aspect of the present invention, there is provided an office equipment component comprising, as a main component, an oxide compound of tin (Sn) and lead (Pb) as a main component, and a heat generating material that generates heat by supplying power is an internal or external surface of the office equipment component. The ion generating material or the ion generating material and the far infrared ray generating material are provided on the surface of the heat generating material. According to the eighth aspect of the present invention, the sheet-like heating element is provided on the inside or the outer surface of a part for office equipment.

1. Since the sheet-like heating element of the present invention uses a heating material mainly composed of an oxide compound of tin (Sn) and lead (Pb), the heat conversion rate is higher than that of other heating materials. After the power is turned on, the rise time to the predetermined temperature is short, the power consumption is reduced, and the running cost is reduced.
2. Since the ion generating material or the ion generating material and the far infrared ray generating material are provided on the surface of the sheet heating element, ions (metal ions) are efficiently generated from the ion generating material heated by the sheet heating element. Various environments such as sterilization, disinfection, sterilization, sterilization, antiseptic, antibacterial, and antifungal improve the surrounding environment of the sheet heating element. Since far infrared rays are generated from the far infrared ray generating material, the heating effect when used in office equipment is improved.
3. Since the sheet-like heating element of the present invention uses the electricity generated by the photovoltaic power generation system as a heating power source, it saves energy and reduces the running cost.
4). Since the rotary roll and office equipment parts of the present invention are provided with a heating material directly or on a sheet-like heating element on the inside or outer surface thereof, the office equipment parts do not become particularly large or heavy. The surface of the roll can be uniformly heated, and condensation on the surface of rotating rolls, parts for office equipment and parts in the vicinity can be prevented. It does not get wet and the printed characters are difficult to smear. Further, when the rotating roll is a fixing roll for a copying machine, the toner tends to adhere.
5). In the case where a heat generating material that is mainly composed of an oxide compound of tin (Sn) and lead (Pb) and generates heat when energized is provided directly on the inside or the outer surface of a rotating roll or a part for office equipment, a sheet-like heating element is provided. Rather than rotating rolls and office equipment parts, the size and weight are reduced.
