    摘要: A tape recorder has a base plate, a capstan rotatably supported by the base plate and a flywheel attached to the capstan. The capstan is rotated by a drive device having a motor and a driving gear mounted on the flywheel coaxial with the capstan. A pair of magnetic heads are movably arranged on the base plate. A moving gear is rotatably supported on the base. A cam member and a push member are mounted on the moving gear. The push member engages with one of the magnetic head to move the head as the moving gear is rotated. A pair of transmission gears are arranged on both sides of the moving gear to be able to engage with the driving gear and moving gear. The transmission gears transmit the driving force of the drive device to the moving gear to rotate the moving gear by engaging with the driving gear and moving gear. The engagement of the transmission gears with the driving gear and moving gear and the rotating angle of the moving gear are controlled by a controlling device.

    摘要: A word line number count/display device used in a tape recorder for dictation includes a magnetic head for detecting a special cue signal from a magnetic recording tape while the tape is running in either of two opposite directions, and for generating a detection signal corresponding to the length of a main communication content of dictation recorded on the tape. A time measuring circuit electrically connected to the magnetic head measures the time length corresponding to the length of the main communication content and generates a time period signal corresponding to the measured time length. A dividing circuit electrically connected to the time measuring circuit divides the time period signal by a predetermined reference time period value to produce a quotient signal, and a multiplying circuit multiplies the quotient signal by a predetermined value corresponding to the average number of words spoken by a dictator during a predetermined period of time divided by the average number of words contained in one line of a typing paper. A resulting product signal is provided to a decoder which produces a digital signal corresponding to the product signal from the multiplying circuit. A digital display device displays digital information corresponding to the digital signal.

    摘要: A mode switching mechanism for a cassette tape recorder is provided with an operation member slidable from neutral position in either of opposite directions. The movement of the operation member is transmitted via a rockable switching lever to a support lever which supports a pinch roller and a magnetic head. The support lever is rocked from a stop mode position to a play mode position or a record mode position, thereby bringing the pinch roller and magnetic head into contact with a magnetic tape. The switching lever is biased by a spring to rock around a first fulcrum member or a second fulcrum member. The operation member has first and second contacts. When the operation member is slid from the neutral position in either direction, the first or second contact hits and rocks the switching lever around the first or second fulcrum member against the force of the spring. Since the switching lever is rocked about the first or second fulcrum member, the distance between either fulcrum member and the point where either contact hits the switching member is sufficiently long whichever direction the operation member is slid.
