Abstract: An external magnet provided outside a sealed container is movable with respect to the sealed container, and an external member moves the external magnet. An internal magnet provided in the sealed container is movable with respect to the sealed container, and an internal member is moved by movement of the internal magnet. The external magnet and the internal magnet are arranged in such a manner that the internal magnet is moved by the action of a repulsive force between the external magnet and the internal magnet based on movement of the external magnet.

Abstract: A switch mechanism for use in medical apparatuses, includes an airtight unit being able to retain airtight therein, a first magnet provided outside the airtight unit, an operation unit provided outside the airtight unit and being able to move the first magnet with respect to the airtight unit, a second magnet provided in the airtight unit and being able to receive a force from the first magnet in accordance with a position of the first magnet, and a switch unit provided in the airtight unit and being able to be switched on and off by using a force acting between the first magnet and the second magnet.

Abstract: An electrical connector having an electrical plug (102) to be plugged into an electrical receptacle (130). The electrical plug (102) includes an electrically insulative plate-like substrate and a plurality of first electrical contacts (118) formed in parallel on at least a side surface at one end of the substrate for a predetermined length from the one end. The plug further includes a shielding part (126) formed of an electrical conductor which substantially shields all of the substrate in a position nearer an end other than the one end having the electrical contacts (118). The electrical receptacle includes an electrically insulative receiving member (138) forming at least part of a recess in which the substrate of the plug is inserted. A plurality of second electrical contacts (142) are arranged in the receiving member (138) so as to contact the plurality of contacts in the plug whenever the substrate of the plug is inserted into the recess.

Abstract: An endoscope apparatus comprising an electrical connector which is electrically connected to an electrical device such as a CCD in an organism inserting device such as an endoscope which has an inserting section inserted into a organism. The electrical connector is connected to an electrical connector receptacle such as a control unit after the organism inserting device has been disinfected and sterilized by disinfection liquid. Processing is first performed in which the liquid remaining in the vicinity of an electrical contact of the electrical connector is removed by a liquid removing mechanism and, thereafter, electrical operation occurs. Thus, generation of a short-circuiting accident is prevented.
