Abstract

PURPOSE: To provide the small-size and highly reliable device through controlling of the intensities and polarity of electric power applied to a coil by mounting yokes and magnets and electromagnetic coil to the carriage moving on the yokes thereby constituting a kind of linear motor.
CONSTITUTION: Carriage 1 mounted with an optical system 2 is moved on yokes by rollers R1, R2, R3, R4 in the X-X directions and is secured with a coil 3. The yokes 4, 5 are constituted by magnetic material and sandwich magnets 6, 7 at the end parts. The magnetic field A going toward the direction orthogonal to the directions X-X is normally held formed in the spaces of the yokes 4, 5 by the magnets 6, 7. When electric power is applied to the coil 3, the magnetic field B in the direction orthogonal to the moving direction of the carriage produces and varying densities of the magnetic field are produced in the directions X-X owing to the mutual action of the magnetic fields A dnd B. The coil 3 is moved by receiving the thrust force going from the dense magnetic field to the coarce magnetic field and the movement direction and speed are controlled by the polarities and intensities of the coil electric power. There is no need for making the entire part of the device large in size.
