    摘要: The invention is concerned with a magnetic recording/playback apparatus in which a magnetic tape is pulled out from a tape cassette and wound around a cylindrical rotary head cylinder, having a rotary head built therein, over a predetermined angle to record/playback signals through the rotary head, and more particularly, with a tape guide post driving mechanism, a pinch roller pressing mechanism and a tension servo mechanism. Specifically, the invention provides a tape guide post driving device which can reduce the size, weight and thickness of the apparatus by ensuring a large angle of rotation of a rotating member, which includes a tension arm, in a direct manner. Also, the invention realizes a pinch roller pressing mechanism in which a sufficient stroke can be obtained even when a cam gear is reduced in its diameter and can provide a sufficient stroke even with a small amount of rotation. Further, the invention prolongs the service life and achieves a remarkable reduction in both the number of parts used and the number of assembling steps by using a pad brake (brake member), instead of a band brake, for braking a rotating member and bringing the brake member into full contact over the former's entire surface with the member being braked.

    摘要: The relates to a loading mechanism which can realizes a miniaturized, light-weight and thin magnetic recording/playback apparatus. A running path of a magnetic tape from a position where the tape leaves out of a rotary head cylinder to a capstan is settled merely with roller posts without any fixed post, whereby a tape running load is considerably decreased. Because the loci of movement of take-up and supply loading boats which are respectively guided along associated loading guides correspond to the loci of revolution of drive shafts fixed on loading rings at take-up and supply sides, the loading boats can be driven directly by the drive shafts, whereby a simplified loading mechanism can be achieved.

    摘要: A cassette loading device is compact, lightweight, thin and used in a video tape player or the like. An opening lever is pivotally mounted on a stand, and is engaged in a cam groove with a top plate. With this arrangement, the opening lever is accommodated within a longitudinal dimension of a cassette, and therefore the loading device in the direction of the longitudinal dimension of the cassette can be greatly reduced. The cassette is moved through the pivotal movement of the top plate and arms, and with this arrangement operating switches and so on can be easily mounted on a plane of projection of the top plate. Therefore, the positional stability of the cassette loading device can be achieved, and the number of component parts can be reduced, thereby achieving a compact, lightweight construction of the cassette loading device.

    摘要: A video recording and playback device with a built-in video camera includes an outer case having the same profile as that of a tape cassette that can be inserted into an exiting stationary video tape recorder. The outer case houses a pair of rotatable reels, a magnetic tape wound around the reels, a magnetic head drum for recording signals on the magnetic tape, magnetic tape guide posts for guiding the magnetic tape to run on and around the magnetic head drum a magnetic tape transport unit for transporting the magnetic tape from one of the reels to the other reel, an imaging unit for producing a video signal representative of an image of an object, a signal recording circuit for processing the video signal from the imaging unit and enabling the magnetic head drum to record the video signal on the magnetic tape, and a power receiving terminal assembly for receiving electric power to energize the motor of the magnetic head drum, the magnetic tape transport unit, the imaging unit, and the signal recording circuit. A recording medium such as a magnetic sheet disk or an optical disk may be employed instead of the magnetic tape.

    摘要: A recording/reproducing apparatus comprising a tape winding device rotationally moving around a tape guide drum for pulling out a tape from a tape cassette and for wrapping the pulled-out tape on the tape guide drum. The tape guide drum advances into an opening portion of the tape cassette on tape loading, resulting in producing a moving space of the tape winding device, and the tape winding device is rotationally moved around the tape guide drum in the produced space between the tape guide drum and the casing section in response to the advancing movement of the tape guide drum. A casing section of the recording/reproducing apparatus and a member operatively associated with the casing section may either enter into the locus of the rotational movement of the tape winding device after the tape winding device is rotationally moved by a predetermined angle.
