摘要:
A recording medium cassette being easily miniaturized if necessary, and a recording and/or reproducing apparatus, such as a VTR, adapted to use the same recording medium cassette. The recording medium cassette includes a printed wiring board having a plurality of information indicating contacts and which is fixed to the bottom wall of a case of the recording medium cassette so that the information indicating contacts are accessible from outside through slots formed in the bottom wall. The recording and/or reproducing apparatus is provided with a plurality of information detecting contacts respectively corresponding to the information indicating contacts of the recording medium cassette. The information detecting contacts may respectively contact the information indicating contacts upon insertion of the recording medium cassette into the recording and/or reproducing apparatus so as to enable information to be transferred therebetween. The VTR is adapted to use both a small-sized tape cassette and a large-sized tape cassette.

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.

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.

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:
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 cassette having one of a plurality of sizes, in which each size cassette is adapted for use with a common cassette recording/reproducing apparatus. Each size cassette includes a cassette case holding a recording medium therein, an information device for providing information pertaining to the respective cassette to the cassette recording/reproducing apparatus when the respective cassette is being used with the cassette recording/reproducing apparatus, and a reference hole for positioning the cassette case in the cassette recording/reproducing apparatus. The reference hole and the information device have a constant positional relationship therebetween regardless of the size of the cassette.
摘要:
A cassette having a recording medium contained therein for use with a recording/reproducing apparatus. The cassette includes a storage device for storing information pertaining to the recording medium and/or the cassette; a plurality of terminals coupled to the storage device and adapted to be coupled to the recording/reproducing apparatus when the cassette is being used therewith so as to transfer the stored information to the recording/reproducing apparatus; and an accidental-erasure prevention switch member located in close proximity to the terminals for inhibiting recording of an information signal onto the recording medium and inhibiting erasing of a previously recorded information signal from the recording medium. At least one hole and a window are provided in the cassette so as to provide access to the terminals and the accidental-erasure prevention switch member. Such at least one hole and window may be arranged so as to provide a relatively large area for fastening a label. The recording/reproducing apparatus includes a connector which is coupled to the terminals when the cassette is inserted and mounted in the recording/reproducing apparatus and adapted to receive the information from the storage device.
