A gimmick device according to one or more embodiments may include a gimmick and a voice coil motors (VCM). The VCM includes a casing, a permanent magnet, a yoke and iron-core, a bobbin, and a coil part. The gimmick is mounted to the casing on a movable side. The coil part includes a drive and primary coil serving as a drive coil and a primary coil of a displacement sensor including a differential transformer, the drive and primary coil being interlinked with a magnetic flux by the permanent magnet, and two secondary coils of the displacement sensor. The yoke and iron-core may be disposed in a central space defined in the coil part, and serves as an iron core of the displacement sensor.

Voice coil motor

An optical switch device () of such a type that the COUPLED state of light guides is switched by moving a light reflective member capable of securely preventing a movable body with the light reflective member from being displaced and allowing a reduction in thickness, comprising a pressing member () switching the movable body () with a prism mirror () mounted thereon between a clamped state and an unclamped state, a twisted spring () energizing the pressing member in a clamping direction, and a magnetic drive circuit () for clamping driving the pressing member () in the unclamped state against the torsion spring (). The magnetic drive circuit () for clamping further comprises a clamp coil () on the fixed member () side and clamp magnets () on the pressing member () side. The clamp magnets () are disposed so as to hold the clamp coil () from the inside and outside of the opening thereof with the different poles thereof opposed to each other.

Optical switch device

An optical switch device for driving a movable member mounting a light reflection member thereon by a magnetic drive circuit, wherein, in an optical waveguide switching device () as an optical switch device, a movable member () mounting thereon an optical waveguide switching prism mirror () is driven in an X direction by a magnetic drive circuit while being floated from a fixing-side member () in order to improve stability of a light outputting position. When the movable member () is moved to a desired position in the X direction, power supply to solenoids () is stopped in a clamp mechanism (), and a clamp plate () presses the movable member () against the fixing-side member () to fix it. A V-groove () formed in the movable member () and a V-groove () formed in the fixing-side member () mesh each other to position the movable member () in the X direction.

The present invention provides an optical switch that is provided with a plurality of output side optical transmission means; at least one input side optical transmission means; reflecting meanswhich moves to be positioned with respect to any one of the output side optical transmission meansand reflects an optical signal to the input side optical transmission means; and driving meanswhich moves the reflecting meansto each of the output side optical transmission means
