Abstract

To improve reliability of a circuit module by improving heat release performance and minimizing thermal influence on a device to be mounted, a base substrate having a first substrate mounted thereon is fitted into a lower portion of casing member, and a second substrate is installed in the upper portion of the casing member so that a spaced area can be provided. In addition, a drive device to be installed on the second substrate is positioned off the center of the second substrate.
