Abstract
PURPOSE:To reduce consuming energy and to copy at a high speed, by constituting so as to displace scanning mirrors mutually in the reverse directions, respectively, also adjusting the mass ratio, and reducing a load owing to gravity to ''0''. CONSTITUTION:A scanning mirror M1 is fixed to a supporting body 15 which is fitted into a guide bar 16 so as to slide freely, and in the same way, a scanning mirror M2 is fixed to a supporting body 17, and they are mutually driven at an equal speed through a wire 19 by a pulley which is fixed to a driving motor shaft 10. In this case, both the mirrors M1, M2 are provided so that mutual displacement is made in the reverse directions, respectively, that is to say, when one of them rises, the other lowers. Also, when the mass ratio of both is adjusted to balance, a load by gravity of the mirror against the driving motor is reduced to ''0''. In this way, the consuming power of a driving motor is reduced, and to cope with copying at a high speed in realizable.
