Abstract
PURPOSE: To eliminate the need for spherical mirrors, etc. and make the construction simple and inexpensive by letting a light beam reflect equal times at each reflecting part of reflecting bodies comprising opposing two plane reflecting parts and position-changing the direct light beam parallel without angle polarization by rotating the reflecting bodies.
CONSTITUTION: For example, in a hologram memory reproduction apparatus, the light beam from a laser light 8 is reflected by the two plane reflecting parts 9a, 9b of a reflecting body 9 which is rotated stepwise by a pulse motor 10. The light beam having been reflected by the plane reflecting part 9b is reflected by the plane reflecting parts 11a, 11b of the second reflecting body 11 which has a revolving shaft orthogonal to the revolving shaft of the reflecting body 9 and is rotated stepwise by a pulse motor 12. The light beam having reflected on the plane reflecting part 11b is radiated to an arbitrary hologram memory of a page constitution hologram memory plate 13 and the image is formed on the face of a photoelectric transducer 15 by a reproducing lens 14, whereby it is converted to an electric signal.
