Headphones include a headband, an arm portion, a pair of headphone units that respectively retain a speaker, a hinge structure that supports the headphone unit at the arm portion, and an oscillator that vibrates the arm portion. The oscillator is contained in a transducer box and clamped and supported by the arm portion and the headband. A vibration conducting unit connects the arm portion with the headphone unit and conducts vibration of the arm portion to the headphone unit.

A thermal dye sublimation printer to which an ink ribbon cassette having a function of transmitting and receiving data via wireless communication with a printer main body is attached, is disclosed. The thermal dye sublimation printer includes: communication means that transmits and receives data via wireless communication with an ink ribbon cassette; and control means that acquires management information of the ink ribbon cassette stored in the ink ribbon cassette side via the communication means and controls printing processing based on the acquired management information.

Thermal dye sublimation printer and ink ribbon cassette therefor

A printer device is disclosed. The printer device includes: a base chassis that accepts therein and ejects therefrom the printing medium; a top chassis that is disposed to be able to freely open and close in a direction vertical to the basis chassis; an ink ribbon cartridge holder that is disposed between the top chassis and the base chassis, and is attached with an ink ribbon cartridge including therein the ink ribbon; and a thermal head that prints an image to the printing medium by heating the ink ribbon in the ink ribbon cartridge attached to the ink ribbon cartridge holder.

The present invention provides a multi-winding motor. Two three-phase exciting windings Sa, Sb are wound on each of the magnetic pole sections of divided cores. Two kinds of discrete winding wirings A, B are wound together with the same winding number onto each of the magnetic pole sectionsA-L of the divided cores. Divided coreswound with the discrete winding wirings A, B are annularly disposed, and are connected in parallel with each other so that the discrete winding wirings are arranged in the order of A, B, A, B . . . within the same connection, and the exciting windings are star-connected to construct two three-phase exciting windings Sa, Sb.
