PROBLEM TO BE SOLVED: To eliminate the need for sufficiently parting the distances of respective moving bodies in order to suppress the crosstalks of magnetic fields of electromagnets corresponding to the moving bodies in order to constitute a multichannel switch and to obviate the difficulty in downsizing. SOLUTION: As an initial state all drive sections 3 are positioned in a negative direction of a y-axis and when an output optical path is formed of an optical fiber 25c, prescribed current is passed to a coil 102c to drive and latch the drive section 3c in the forward direction of the y-axis. At this time, the optical fiber 22 which is the input optical path and the optical fiber 25c is optically coupled and the light past a distributed refractive index fiber 123 from the optical fiber 22 is reflected by a reflection mirror 16c existing on its optical axis and arrives at the optical fiber 25c by passing a distributed refractive index fiber 124c. |
