Abstract: 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 serve 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 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.

Abstract: An apparatus for quick starting of tape forwardly-and-rewinding operation for video cassette recorders, wherein fast-forwarding or rewinding operation of a video tape can be quickly started, because loading plates, which are locked in loading holes as during the recording or reproducing operation, keep the tape being loaded on a head drum, while the tape can be wound by only the driving force to rotate one of the reel discs, because two guide grooves in different shapes are provided on upper and lower surfaces of a cam gear and so a tension pole and a pinch roller come off the tape and the tape gets out of touch with various fixed posts in its travelling route, before the fast-forwarding or rewinding operation is started.

Abstract: Disclosed is a magnetic recording and reproducing apparatus of the rotating head type in which a magnetic tape is drawn out from a tape cassette by means of tape lead-out pins and brought into close contact with a head cylinder containing rotating heads. Each of the tape lead-out pins is mounted on a slide member which is adapted to be driven by a drive means and slideably guided along a guide path consisting of a guide slot formed in a base plate of the apparatus. With such arrangement, the guide path need not coincide with the path of the driving means, whereby the tape loading mechanism and hence the apparatus as a whole can be small in size.

Abstract: A chassis is provided with a pair of leading guide blocks slidably fitted in respective guide slots for withdrawing a tape from a cassette, loading links for slidingly moving the respective guide blocks, and catchers arranged on the chassis at a loading completed position for the respective guide blocks to come into pressing contact with. Each of the loading links comprises a pivotal lever rotatably fitting around a pivot on the chassis and a link plate connected by a pivot pin to a free end of the pivotal lever and rotatably engaged at a forward end thereof with the guide block. The chassis is formed with apertures permitting insertion of the respective guide blocks therein, each covered with the catcher and each communicating with the guide slot. The aperture is positioned at a greater distance from the pivot than the forward end of the link plate when a center line L1 connecting the pivot and the pivot pin and a center line L2 connecting the pivot pin and the portion of connection between the guide block and the link plate extend toward the direction of loading in alignment with each other.

Abstract: 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.

Abstract: A tape loading mechanism of a video tape recorder designed to play a standard size tape cassette and a compact size tape casette comprises a chassis carrying a pair of guide grooves at both sides of a guide drum toward a first area of the chassis on which the standard size tape cassette is held at the time of operation of the video tape recorder. The guide grooves are further extended toward a second area of the chassis defined inside the first area on which the compact size tape cassette is held. A pair of loading members are moved along the guide grooves toward their front ends close to the tape cassette when the compact size tape cassette is loaded so that loading poles in the loading members are accepted in a cutout portion formed at a front side of the compact size tape cassette. Further, the loading members are displaced toward the rear end of the guide grooves when the standard size tape cassette is loaded so that the loading poles are accepted in a depressed part formed at a front side of the standard size tape cassette. A light emitting element for detection of the end of the tape is held rotatably on an arm and changes in position responsive to the type of the tape cassette. A deformable member is provided on a tension arm which is connected to a brake member for applying resistance to the rotation of the supply reel, so as to avoid excessive slackening of the brake member when the tension arm is rotated to a position adapted for loading the compact size tape cassette. Further, a half loading arm is provided so as to prevent complete loading of the magnetic tape on the guide drum during high speed transportation of the magnetic tape.
