LIGHT SOURCE APPARATUS, OPTICAL SCANNING APPARATUS, AND IMAGE FORMING APPARATUS

摘要

<P>PROBLEM TO BE SOLVED: To prevent temperature in a light source apparatus from being raised to stably emit laser light. Ž<P>SOLUTION: Temperatures generated in each of VCSELs are collected to be discharged to an outside air through: a ground pad 10c formed on a case 10b; a first and second lands 76c and 76d formed on a substrate 76; a biasing member 78 where a pressing part 78c comes into contact with the second land 76d; and heat-receiving parts 81a formed on a heat pipe 81. Moreover, heats conducted from a circuit and electric element provided on the substrate 76 to a light source 10 through the substrate 76 is collected to be discharged to the outside air through: the first and second lands 76c and 76d formed on the substrate 76; the biasing member 78 where the pressing part 78c comes into contact with the second land 76d; and the heat-receiving parts 81a formed on the heat pipe 81.
