Light source and color thermal printer using the same

摘要

A yellow fixing light source of a color thermal printer comprises an aluminum substrate, light emitting elements aligned thereon, and reflectors mounted thereon. The reflector reflects the light emitted from the light emitting element. A part of a power line constituting a wiring pattern is formed on a glass epoxy plate of the reflector. The wiring pattern is prevented from having a dense portion and becomes a simple form. Thus, it is possible to reduce a cost to be taken for forming the wiring pattern. A degree of freedom for raying out the wiring pattern increases and a breadth of the wiring pattern may be widened so that it is possible to prevent luminous unevenness from being caused due to voltage drop to be induced by wiring resistance.
