Abstract: A cassette tape recorder wherein a tape cassette ejecting mechanism and a magnetic head shifting mechanism are alternatively driven by a common driving mechanism of a simple construction including a tape feeding drive motor. The tape recorder includes a selectively engaging mechanism which operates by a predetermined amount when actuated, and a driving force transmitting member which is operated by the selectively engaging mechanism and moved between first and second positions by a head holding mechanism. When a tape cassette is to be ejected, the driving force transmitting member is moved to the first position in which it operates an ejecting mechanism. When a tape cassette is loaded into an operative position, the driving force transmitting member is moved to the second position in which it operates a head shifting mechanism to shift a magnetic head and a pinch roller to their operative positions at which they are thereafter held by the head holding mechanism.

Abstract: An automatic stopping device for a tape feeding apparatus which can assuredly detect that a tape is wound to its last end and can stop feeding of the tape not only in a reproduction mode but also in a fast feeding mode of the tape feeding apparatus. Stopping of rotation of a reel shaft is detected by a frictionally cooperating cam follower which is thereupon disengaged from a circular cam and engaged with an operating element both on a turning force transmitting member to pivot a pivotal member so that the turning force transmitting member on the pivotal member is moved out of a turning force transmitting route from a capstan shaft to the reel shaft and a switch is operated to deenergize a motor connected to the capstan shaft. After stopping of the motor, a movable member may be manually moved to a rest mode position in which the cam follower is engaged with the circular cam again.

Abstract: A cassette tape recorder wherein lateral widthwise movement of a tape can be limited to assure stabilized feeding of the tape and prevent eventual damage to the tape. The tape recorder comprises a pair of cassette guide posts securely mounted on a stationary main base plate, and a tape guide mounted on a movable head carrying plate and having an upper widthwise movement limiting projection and a lower shorter widthwise movement limiting projection formed respectively adjacent upper and lower ends of a tape contacting face thereof for limiting lateral widthwise movement of a tape being fed along the tape contacting face of the tape guide. At least one of the cassette guide posts which opposes to the tape guide has a tapering profile presenting a lower large diameter portion and an upper small diameter portion which are opposed respectively to the lower and upper widthwise controlling projections of the tape guide.

Abstract: A dubbing tape recorder includes first and second tape drive units having independent recording or playback functions and mechanical portions of substantially the same structure and dimensions and nmounted respectively on separate chassis of substantially the same structure and dimensions. The drive units are arranged side by side as unitary subassemblies and are both driven by a common motor to drive their associated tapes. A common switch adapted for the actuation of the motor is disposed at a left or right end portion of the tape recorder. A switch operating mechanism which is actuated in the same manner no matter which one of the tape drive units is operated to actuate the motor is also arranged extending over both of the tape drive units. The switch is changed over by the switch operating mechanism to actuate the motor.

Abstract: An automatic stopping mechanism for a tape feeding device which can detect an end of a tape to operate while the tape feeding device is in any of reproducing, recording, fast feeding and rewinding modes. In any operation mode, a driving route from a motor to a reel receiver is effective to tend to continuously rotate the reel receiver. Upon stopping of the reel receiver by an end of a tape, a rockable member is rocked to and remains at a position at which rotation of an cam disk interposed in the driving route is stopped by the rockable member and then a releasing member on which the cam disk is mounted is pivoted to move the cam disk out of the driving route, thereby stopping rotation of the reel receiver.

When the arresting member is at a retracted position, the ejecting member is prevented from moving from a retracted position to the advanced position, but when the arresting member is moved form the retracted to the advanced position, the ejecting member is allowed to move from the retracted to the advanced position to eject a tape cassette from the tape recorder.

Abstract: A dubbing tape recorder is constructed of first and second tape drive mechanisms capable of performing playback and recording operations respectively; a playback control member for holding the first tape drive mechanism in a playback mode at its operating position, said playback control member having an engaging portion; a recording control member for maintaining the second tape drive mechanism in a recording mode at an operating position; a pause control member for setting the recording mode into a waiting state while the recording control member is held at its operating position; a pause lock mechanism for holding the pause control member at its operating position; and a pause release mechanism having an engaged portion. The pause release mechanism is actuated by an engagement between the engaging portion and engaged portion only when the playback control member moves toward its operating position.

Abstract: An auto-reverse tape recorder has an FF(fast forward) control, rewinding control and restraining members. The FF control member is movable forward so that when a magnetic head and a pinch roller are at operating positions, the head and roller are once caused to retreat toward their stop positions. The FF control member causes the head and roller to return to their operating positions when the FF control member returns to its non-operated position. The rewinding control member is movable forward so that when the head and roller are at the operating positions, the head and roller are once caused to retreat toward stop positions. The rewinding control member causes the head and roller to return to the operating positions when the rewinding control member returns to its non-operated position.

Abstract: Disclosed herein is an automatic reverse mechanism for a tape recorder. The mechanism can automatically reverse the A and B sides of a magnetic tape. Rotary forces from capstans provided on both sides of a magnetic head are transmitted to their corresponding reel shafts, which are provided in a pair symmetrically relative to a magnetic head, by way of their corresponding rotation transmitting members. Based on results of a detection by a mechanical detector capable of detecting a stop of one of the reel shafts, a rotary force is transmitted to the other reel shaft via its corresponding rotation transmitting member by a changeover bar so that the running direction of the magnetic tape is reversed automatically.

The tape recorder comprises a detecting member frictionally engaged with the reel receiving member so that while the reel receiving member is rotating, the detecting member produces an urging force in a direction.

Abstract: An automatic recording apparatus which is simplified in construction and reduced in number of parts and in overall size without having a bad influence on an automatic recording function thereof. In the apparatus, a stand-by mode selecting operating member manually pushed in to an actuated position is arrested by an arresting member. In the actuated position of the operating member, rotation of a rotary member is stopped and a reel receiver is disconnected from the rotary member. After lapse of a preset time, rotation of the rotary member is started again. Within one full rotation of the rotary member, the arresting member is moved out of arresting engagement with the operating member by a turning force of the rotary member so that the operating member is returned to its home position, thereby allowing the automatic recording apparatus to start a recording operation.
