(Embodiment 3)
In the first and second embodiments, between the gate device 3, the basic function module 8 (including the voice information transmission device 8a), and the extended function module 10 (including the voice information transmission device 10a), the power path and information by the connector connection The road has been built.

  However, in this embodiment, the power path is configured by supplying electric power in a non-contact manner by magnetic coupling instead of connector connection. Specifically, the gate device 3, the basic function module 8, and the extended function module 10 each have a configuration in which a coil is wound around a core instead of a connector, and the cores are magnetically coupled to each other so that the other coil has a low pressure. AC power supply voltage is induced to supply power. Here, by applying an AC power supply having a frequency higher than the commercial frequency to the coil, the transformer configuration by the electromagnetic coupling portion can be reduced in size.

  Further, in the gate device 3, the basic function module 8, and the extended function module 10, an information signal is sent out through E / O conversion, and an information signal is taken in through O / E conversion, whereby an information signal composed of an optical signal is emitted as a light emitting element. Thus, an information path that can be transmitted bidirectionally without contact using the light receiving element is constructed.
