Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the case where heating and drying are performed in, for example, a heat treatment of a metal material, a molding and heating of a resin or the like, a synthetic resin film or a papermaking molding process. It has a main reflection mirror at the center and sub-reflection mirrors on both sides of the main reflection mirror. The strongest main reflection beam reflected by the main reflection mirror and the sub-reflection The present invention relates to a multi-stage reflecting mirror mechanism in which a part of a sub-reflected beam reflected by a mirror and a remaining sub-reflected beam are effectively combined and condensed on a focal point. 2. Description of the Related Art In the case of heating, drying and the like of metal sheets, resin sheets, papermaking sheets and other similar sheet materials, for example, heat sources generally have various diameters. Roll heaters were used. However, it is extremely difficult to uniformly heat the sheet material with a rotating roll heater, and not only cannot uniform heating be caused due to uneven heating, but also the roll diameter is limited and high heat energy cannot be obtained. Since the heating and drying by rotation are not efficient, there are various problems as described above. As described above, in the case of using a roll heater, the amount of heat that can be obtained is limited, and as the width of the sheet material increases, uniform heating becomes more difficult. For this reason, a heat source lamp is incorporated in a reflection mirror, a beam from the heat source lamp is reflected on a reflection surface to generate a high heat reflection beam, and the beam is used as a heat source. However, since the amount of heat obtained depends on a single lamp capacity, the amount of heat was also limited. Therefore, in order to increase the amount of heat of the reflected beam, it has been attempted to parallelly reflect the reflected beam to perform processing by paralleling a plurality of reflecting mirrors. I could only get light. [0004] On the other hand, in recent years, the production line for this type of sheet material has been increasingly speeding up and the sheet material itself has tended to be wider. Accordingly, there has long been a demand for a heat source capable of producing a high-heat beam capable of uniformly and instantaneously processing heating and drying processing over the entire sheet material in order to cope with those conditions. No heat source system has been proposed. The inventors of the present invention have conducted intensive studies in view of the above circumstances, and as a result, despite being a compact reflecting mirror, a high heat quantity beam is generated by an organic combination of reflected beams, and a line-shaped focal point is formed on a processed portion. We succeeded in developing a multi-stage reflecting mirror that can connect the mirrors, and completed the present invention. It is an object of the present invention to provide a reflecting mirror which is preferable as a heat source in the case of heating or drying various sheet materials. The reflecting mirror is reflected by the main reflecting mirror and the strongest main reflecting beam reflected by the main reflecting mirror. It is an object of the present invention to provide a multi-stage reflecting mirror mechanism capable of obtaining a reflected beam having a very high calorific value by condensing all the sub-reflected beams to a focal point without irregularly reflecting the reflected beams. Further, the object of the present invention, when attaching and detaching the desired length of the main heat source lamp and the sub heat source lamp to the desired length of the main reflection mirror and the sub reflection mirror,
