Abstract A tape cassette comprises a cassette housing (1) having an upper section (2), a lower section (3), a pair of reel hubs (5a, 5b) rotatably accommodated therein for winding a magnetic tape (6) therearound, and a front opening through which the tape (6) is engageable with a recording and/or reproducing head. The lower section (3) is formed with a pair of openings (4a, 4b) for respectively receiving reel shafts for rotating the hubs (5a, 5b) and thereby driving the tape (6), and the upper section is formed with a recess (10, 12). A tape player with which the cassette cooperates is provided with a holder (14b) for the cassette, with a loading hook (11a) engageable in the recess (10, 12) in the upper cassette section, and with an arrangement of cams and levers for moving the loading hook (11a) between an ejection position wherein the tape cassette can be manually inserted partway into or removed from the cassette holder (14b) and a loaded position wherein an inserted cassette is fully drawn into the holder (14b), and for moving the holder (14b) between an upper position wherein a cassette can be loaded into or ejected from the holder (14b) and a lower position wherein a cassette loaded into the holder (14b) engages a tape drive.
A tape cassette comprising: a cassette housing having an upper section and a lower section; a pair of reel hubs for winding therearound a magnetic tape, said hubs being rotatably accommodated in said cassette housing; said lower section being formed with a pair of openings for respectively receiving a pair of reel shafts for rotating said hubs and thereby driving said tape; said housing being formed with a front opening through which said tape is engageable with a recording and/or reproducing head; front lid means pivotally supported at opposite, left and right sides of said cassette housing and movable between a closed position wherein it covers said front opening and an open position wherein it uncovers said front openings; said upper section having an upper surface formed with an engagement portion which is integral and immovable with respect to said supper section and separate from said front lid means and comprises a rectangular groove formed in said upper section at a position intermediate in a left-to-right direction of said cassette housing and adjacent to said front opening, said groove being formed with a planar bottom wall and a planar front wall defining a right dihedral angle, said planar front wall extending to said upper surface of said upper section, and said front wall of said groove being selectively engageable with and disengageable from loading means formed on recording and/or reproducing apparatus when said cassette housing is loaded into said apparatus, whereby said loading means can move said cassette housing within said apparatus in a direction substantially perpendicular to said front wall.
