摘要： A tape supplying and taking up apparatus is capable of use with either large or small size tape cassettes containing reels which can be of different diameters and rotated with a high degree of accuracy by reel spindles of simple structure. Each tape cassette for use with the apparatus has a shutter of the slide type for closing access holes in the bottom wall of the cassette casing.Each of the reel spindles has a large size cassette receiving portion for receiving a tape reel of a large size tape cassette coaxial with a small size cassette receiving portion for receiving a tape reel of a small size tape cassette. The small size cassette receiving portion is smaller in diameter and disposed at a higher position than the large size cassette receiving portion. The diameter of a lower end of a reel spindle engaging hole provided in each reel hub of the small tape cassette is smaller than the outer diameter of the small size cassette receiving portion of the reel spindle. The reel spindle engaging hole of the large size tape cassette has, at a lower end portion thereof, an escape portion which is greater in diameter than the outer diameter of the small size cassette receiving portion of the reel spindle but smaller than the outer diameter of the large size cassette receiving portion and such escape portion is higher than the height of the small size tape receiving portion.

摘要： A tape cassette comprises a case body having a mouth formed in the front portion thereof, a front lid pivotally supported thereon so as to cover the open front side of the case body, and a back lid pivotally joined to the front lid so as to cover a space extending behind the substantially lower half of an exposed portion of a magnetic tape in the mouth. The front lid includes a front wall covering the front opening of the mouth, side walls extending backward from the opposite side edges of the front wall, an upper wall covering the upper opening of the mouth, and a back wall extending downward from the upper wall. The side wall is provided with two guide grooves with two round projections projecting from the inner surface of the side wall being respectively received therein. Each of the two guide grooves has the shape of an arc of a circle having its center at the center of an imaginary circle at one end of the other guide groove. When the front lid is turned toward its opening position, one of the round projections moves first along the corresponding guide groove at the initial stage of turning of the front lid, and then the other round projection moves along the corresponding guide groove at the final stage of turning of the front lid.

摘要： In a tape cassette having a case with a mouth for receiving a magnetic head drum of a recording/reproducing apparatus and containing a recording tape wound on rotatable reels and including a tape run extending across the mouth; a front lid is pivotally supported on side walls of the case so as to be movable between a closed position covering a front opening of the mouth and opened position to uncover the tape run, and upper lid is pivotally joined at its front edge to the upper edge portion of the front lid so as to be movable between a closed position to covering a top opening of the mouth and opened position to uncover the top opening, and a slide shutter is supported on the case for sliding between a closed position covering a bottom opening of the mouth and opened position to uncover such bottom opening. The mouth across which a run of the recording tape extends can be closely covered by the front lid, the upper lid and the slide shutter when the tape cassette is not in use. When the tape cassette is in use, the mouth is fully opened in response to the movements of the front lid, upper lid and slide shutter to this opened position so as to enable the magnetic head drum to advance deep into the mouth.

摘要： A tape cassette has a substantially rectangular, box-shaped casing with a recess in a front portion of the casing having openings facing forwardly and downwardly, respectively, and with a bottom wall of the casing having an undersurface including cassette height determining portions adjacent the front and back of the casing and a slide surface portion therebetween which is planar and recessed relative to at least the cassette height determining portions adjacent the back of the casing. A lid is pivotally mounted on the casing for movements between a closed position extending across the opening facing forwardly from the recess and a raised opened position uncovering the forwardly facing opening, and a tape is wound about reels rotatable in the casing and extends between the reels in a path including a run extending across the forwardly facing opening so as to be disposed in back of the lid in its closed position. A shutter includes a lateral portion extending across the undersurface of the bottom wall and being slidable relative to the slide surface portion between a closed position in which the shutter closes the opening facing downwardly from the recess and a rearwardly displaced opened position uncovering such opening. The lateral portion of the shutter is dimensioned to be contained within the recessed slide surface portion in at least the opened position of the shutter so as to avoid any interference with access to the cassette height determining portions of the undersurface.

摘要： A recording/reproducing apparatus within which tape cassettes of different sizes are installable includes a tension regulator arm, pivotably supported by a base plate, and in elastic contact with the magnetic tape withdrawn from the tape cassette, and a tension regulating belt, attached to the tension regulator arm at one end thereof, and in slidable contact with a reel mount to apply a braking force thereto, the braking force being altered according to the position of the reel mount. The braking force applied by the tension regulating belt to the reel mount is less when a smaller sized tape cassette is positioned in the apparatus as compared to when a larger sized tape cassette is positioned therein.
