Wireless terminal devices (TA) to (TH) each detects whether channel information received from each of repeaters (1111) to (111n) indicates an occupied state or an idle state, and when detecting a channel in an idle state, writes identification information of that channel in a RAM (23). The wireless terminal devices (TA) to (TH) each selects a piece of identification information of a channel among plural pieces of identification information of a channel written in the RAM (23) to start making a call to a channel of the selected identification information.

An optical disc apparatus including first to fourth disc guides. At the end of disc loading, the first one, in a fixed position, contacts a peripheral side face of the optical disc at a first point thereon to support the disc; the second one has a plane opposite to the peripheral side face which contacts the peripheral side face of the optical disc at a second point to support the disc while restrained from moving away from the side face; the third one contacts the peripheral side face of the optical disc at a third point to support the disc while biased by a spring; and the fourth one contacts the side face at a fourth point while biased by a spring to support the disc, and is restrained from moving against the resilience of the spring. The disc, supported by those disc guides, is chucked by a clamper.

A linear motor system that can extend the stroke of a linear motor, with power saving and at a low cost, is provided.In a linear motor system, constituted by a linear motor 100, a controller 7 for supplying a variable voltage, a winding switching device 6, for opening and closing phase windings 5 of individual phases that form a plurality of winding groups 4 that are separated in a stroke direction, the winding switching device 6 is constituted by a three-phase rectifying member, a semiconductor switch, which is located at both ends on the direct-current output side of the three-phase rectifying member, and a resistor and a capacitor, connected in parallel to the semiconductor switch. For each of the phase windings, which form the plurality of winding groups 4, separated in the stroke direction, one end is connected to the output end of the controller 7 and the other end is connected to an alternating-current input side of the three-phase rectifying member of the winding switching device 6. And by opening or closing the semiconductor switch included in the winding switching device 6, of the plurality of winding groups 4 separated in the stroke direction, only a desired winding group 4 is excited.
