    摘要： In one aspect of the present invention, an optical image synthesizer is adapted such that there is provided a partial mirror at the junction of two projecting axes with an angle of 45.degree. with respect to these optical axes for the purpose of projecting a composite image onto a screen. By selectively moving the partial mirror about its rotation axis into the above-mentioned angular position and out of one of the projection ranges, composed images and pre-composed are respectively projected onto the screen. Preferably, the distance between the principal points of respective lenses and the screen are equal to each other within an optical system including the lenses, the mirror and the screen. A source of illuminating light for photographs is focused by means of a cylindrical lens. Means are provided for moving the level of the partial mirror along its height. A microswitch is disposed to sense a photograph holder inserted and energize the illumination lamp only when the holder is sensed. Moreover, it is preferable that a shutter be disposed at an optical path between the mirror and the illumination light source to hide an undesirable image from view. The photographs are made slidable in a vertical direction by use of an adjusting device. When composing a combination of a new coiffure and the face of a customer is desirable, the optical axis of a zoom lens is fixed at the eye-to-eye center of the customer to eliminate any definite boundary therebetween. Preferably, markings indicative of the level of eyes and the center of faces are formed at a facelike aperture in the photograph holder.
