    摘要: A viscous fluid type heat generator including a housing assembly defining a heat generating chamber, a fluid storing chamber communicated through fluid passageway means with the heat generating chamber, and a heat receiving chamber for permitting a heat exchanging fluid to circulate therethrough to receive heat from the heat generating chamber. A rotor element is mounted on a drive shaft for rotation in the heat generating chamber with a gap defined between the inner wall surfaces of the heat generating chamber and the outer faces of the rotor element. The fluid passageway means includes a fluid withdrawing passageway for withdrawing the viscous fluid from the gap into the fluid storing chamber and a fluid supply passageway for supplying the viscous fluid from the fluid storing chamber into the gap. The fluid withdrawing passageway has a separate duct configuration and opens at one end to an outer peripheral region of the heat generating chamber to communicate the outer peripheral region with the fluid storing chamber. The fluid supply passageway has a separate duct configuration and opens at one end to a radially inner region of the heat generating chamber to communicate the radially inner region with the fluid storing chamber.

    摘要: A fixing unit includes a heat roller accommodating a heater and a press roller movable toward and away from the heat roller. Both shaft members of the heat roller are supported by two receiving members, with a clearance provided between each shaft member and respective receiving member. A driven gear is provided to one of the shaft member, which engages a rotating mechanism for rotating the heat roller. The fixing unit further includes a biasing member which biases the other shaft of the heat roller away from the press roller within the clearance, in such a manner that the heat roller and the press roller become parallel when the above-described one shaft member is urged away from the press roller due to the meshing engagement of the driven gear and the rotating mechanism.

    摘要: A transmitter-receiver comprises a transmitter, a transmitter circuit, a receiver circuit, a receiver, a jack, and a switch. The transmitter circuit converts a first audio signal to a transmit signal and transmits the transmit signal. The receiver circuit extracts a second audio signal from a received signal. The jack is adapted to be connected with a plug of an external transmitter-receiver. The switch is on/off controlled dependent on whether or not the jack of the external transmitter-receiver is connected with the plug. The switch, when the jack is not connected with the plug, supplies the first audio signal from the transmitter to the transmitter circuit and also supplies the second audio signal from the receiver circuit selectively to the receiver. Further, the switch, when the jack is connected with the plug, supplies an input signal from the external transmitter-receiver to the transmitter circuit through the connected plug and jack and also supplies the second audio signal from the receiver circuit selectively to the external transmitter-receiver through the connected jack and plug.

    摘要: A printer, for printing on continuous recording paper, includes tractors disposed in the recording paper feed path of the printer, with each of the tractors circumferentially travelling in synchronism with movement of the continuous recording paper when the tractors engage feed holes of the continuous paper. When no printing operation is performed, travel of the tractors can be prevented by operation of an electromagnetic clutch, or a combination of one way clutches. Further, the printer uses an electrophotographic method wherein when no printing operation is performed, a transfer charger or fixing roller can be retracted from an operational position. A lever, associated with movement of the transfer charge or fixing roller, is pressed against and locked with the pulley fixed to the rotating shaft of each of the tractors to thereby prohibit the movement of the tractor. Further, a swingable arm can be provided having an engaging projection capable of being locked with the feed holes of the continuous recording paper. The swingable arm is swung in association with the movement of the transfer charger or fixing roller, which can be retracted from the operational position when no printing operation is performed. Thus, the engaging projection is engaged with the feed hole of the continuous recording paper to thereby regulate the movement of the continuous recording paper.
