<p>In a configuration where a circuit board is divided into a digital circuit board (40) and a power supply circuit board (30) arranged at respective sides of an optical disk loader (20), the level of unwanted emission is reduced significantly by modifying the division of grounding patterns of the digital circuit board (40), and arranging a filter on the digital circuit board (40) adjacent to connectors (46-48). Accordingly, a metal case is dispensable, and a resin case can be employed. Therefore, the cost of a DVD apparatus can be reduced.
