Abstract: PURPOSE:To decrease the reverse V segregation, top segregation, hole type defects, etc. of a thin-walled steel ingot and to improve the yield thereof by forming a casting mold for a specified weight or about of the flat steel ingot into a specifically sized shape which is large in the wall thickness of the lower part and has a specified rate or below of an upwardly expanding taper. CONSTITUTION:The sized and shape of the casting mold for >=30t flat steel ingot are specified to the specific relations expressed by the equation I- equation IV, where M: the own weight of the casting mold, I: the own weight of the steel ingot, H: the height of the casting mold, D: the average thickness of the steel ingot, W: the average width of the steel ingot, D1: the distance between the top ends on the long side surfaces of the casting mold, D2: the distance between the top and bottom end thereof, d1: the wall thickness at the top end on the long side surface of the casting mold, d2: the wall thickness at the bottom end of said top surface. The steel ingot is made thin film if the casting mold is formed to such size relations. The wall thickness of the casting mold is made thinner toward the lower part and the upwardly expanding taper quantity is kept at <=2% by which the reverse V segregation and top segregation are decreased and the vertical distribution of C is made uniform. The hole type defects are decreased and the yield of the good steel ingot is improved. In addition, the cost of heating and rolling is decreased.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an image defect due to stray light with a simple constitution in the case of constituting a spray paint type optical scanner of an over-field type optical system. SOLUTION: A 1st light source optical system and a 1st scanning optical system are arranged on one side of a rotary polygon mirror 14 and a 2nd light source optical system and a 2nd scanning optical system are arranged on the other side of the mirror 14. The elevation angle β1 (an angle formed by a plane B rectangular to the rotation axis A of the mirror 14 and an optical beam L1) of the optical beam L1 made incident from the 1st light source optical system on the reflection face 14A of the mirror 14 from the reflection face 14A is made different from the elevation angle β2 of an optical beam L2 made incident from the 2nd light source optical system on the reflection face 14B of the mirror 14 from the reflection face 14B.  Since an optical beam (stray light) reflected by a reflection face different from a reflection face for reflecting light in a recording medium is not applied to another recording medium, the generation of a ghost in the recording medium can be prevented.
