Abstract: A tape cassette (1) including a cassette case (2) having a pair of tape reels (11) having a recording tape (10) wound therebetween and having an opening (6) for providing access to the recording tape (10); a main lid (24) pivotably mounted on opposite side faces of the cassette case (2); a top lid (34) pivotably mounted on the main lid (24); and a guide apparatus. Upon opening or closing the main lid (24) so as to provide access to the magnetic tape (10), the top lid (34) is respecively moved rearwardly from a postion in which the top lid (34) covers an upper portion of the opening (6) or forwardly so as to cover the upper portion of the opening (6). The guide apparatus guides the top lid (34) during such movement thereof so as to avoid sliding or rubbing of a lower face of the top lid (34) on an upper face of the cassette case (2).

Abstract: Cassette (1, 61) having a plurality of sizes are provided, each size cassette being arranged for use with a common cassette recording/reproducing apparatus (201). 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. A recording/reproducing apparatus for use with such cassettes is also provided.

Abstract: In a tape cassette having a case (2) with a mouth for receiving a magnetic head drum of a recording/reproducing apparatus and containing a recording tape (3) wound on rotatable reels (4) and including a tape run extending across the mouth: a front lid (20) 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; an upper lid (28) 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 an opened position to uncover the top opening; and a slide shutter (17) is supported on the case for sliding between a closed position covering a bottom opening of the mouth and an opened position to uncover such bottom opening. The mouth across which a run of the recording tape (3) extends can be closely covered by the front lid (20), the upper lid (28) and the slide shutter (17) 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.

Abstract: A recording/reproducing apparatus (19) for recording information on and reproducing recorded information from the recording medium of a recording medium cassette (1) comprises a cassette identifying circuit (49) capable of identifying a first recording medium cassette provided with an IC plate (4) provided with an IC chip (15; 47) and a plurality of terminals (5) connected to the IC chip (15; 47) in a specified circuit pattern representing information about the first recording medium cassette and a second recording medium cassette provided with a terminal plate (16) provided with a plurality of terminals (17) connected in a specified circuit pattern representing information about the second recording medium cassette. The cassette identifying circuit (49) identifies the first (second) recording medium cassette automatically on the basis of voltage signals that appear at the plurality of terminals (5 (17)) of the first (second) recording medium cassette when the first (second) recording medium cassette is inserted in the recording/reproducing apparatus (19) to enable the user to use the first and second recording medium cassettes indiscriminately.

Abstract: 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. i

Abstract: A tape cassette has a substantially rectangular, boxshaped 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 process to the cassette height determining portions of the undersurface.

Abstract: PATENT 450100.2716 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.
