Abstract
A radiator plate is formed in a slender shape of which the length is such that a plurality of heat emitting elements are attached to the radiator plate arranged substantially in one row at necessary spatial intervals. The printed circuit board is also formed in a slender shape of which length corresponds to the length of the radiator plate. The power input unit is disposed at one longitudinal end of the slender printed circuit board, and the power output unit is disposed at the other longitudinal end of the slender printed circuit board. Accordingly, the power circuit device may be incorporated in apparatus such as an electrophotographic copying apparatus within a vacant space therein, making efficient use of such space. Thus, the apparatus requires no special space for housing the power circuit device. This enables reducing of the dye of the apparatus in its entirety. Further, the power input unit and the power output unit are sufficiently separated from each other on the printed circuit board. This reduces the interference of the power input unit and the power output unit with each other, resulting in reduction in power noise.
