An optical printer capable of being decreased in the number of parts, small-sized and weight. A plurality of color filters are selectively alternated or changed with each other with respect to a common luminous section and such changing-over among the filters is carried out using a transfer unit for a print head, resulting in only one set of the luminous section and optical system being required. Also, power required for alternating or changing the filters with each other Is obtained by the transfer unit for the print head without arranging any specific unit.
