Tape cassette

Claim 2

Apparatus for driving a magnetic tape, comprising: a cassette body having openings formed on two opposed sides thereof; fixedly positioned supply and take-up reels rotatably mounted in said cassette body, the centers of said reels lying on a line which forms an acute angle with the longitudinal axis of said cassette body, said reels having flanged portions extending out of said cassette body through said openings, one on each of said opposed sides of said cassette body; rollers positioned adjacent the exposed portion of each of said flanged portions; and means for selectively engaging each of said rollers with its cooperating flanged portion to drive said supply and take-up reels for winding and rewinding a magnetic tape on said reels.

Claim 3

Apparatus for driving a magnetic tape, comprising: a cassette body having openings formed on at least one side thereof; supply and take-up reels rotatably mounted in said cassette body, said reels having flanged portions extending out of said cassette body through said openings; first and second rollers positioned adjacent the exposed flanged portions of said supply and take-up reels, respectively, for alternately transmitting a rotating motion to said reels for winding and rewinding a magnetic tape on said reels; lever means coupled with said first and second rollers for selectively engaging said rollers with their respective cooperating flanged portions to drive said supply and take-up reels; an idler member; and means rotating said idler member in one direction; wherein said openings are formed on the same side wall of said cassette body; and wherein said lever means comprises a sliding lever and an arm connected to said sliding lever and mounted for rotation about the axis of rotation of said idler member, said first and second rollers being mounted on said arm in contact with said idler member, said arm being rotated by sliding movement of said sliding lever to selectively engage said first and second rollers in pressure contact with the exposed flanged portions of said supply and take-up reels, respectively, to transmit a rotating motion of said idler member to the selected one of said supply and take-up reels.

Claim 4

Apparatus for driving a magnetic tape, comprising: a cassette body having openings formed on at least one side thereof; supply and take-up reels rotatably mounted in said cassette body, said reels having flanged portions extending out of said cassette body through said openings; first and second rollers positioned adjacent the exposed flanged portions of said supply and take-up reels, respectively, for alternately transmitting a rotating motion to said reels for winding and rewinding a magnetic tape on said reels; lever means coupled with said first and second rollers for selectively engaging said rollers with their respective cooperating flanged portions to drive said supply and take-up reels; an idler member; and means rotating said idler member in one direction; wherein said openings are formed on the same side wall of said cassette body; and wherein said lever means comprises a sliding lever and an arm connected to said sliding lever and mounted for rotation about the axis of rotation of said idler member, said first and second rollers being mounted on said arm in contact with said idler member, said arm being rotated by sliding movement of said sliding lever to selectively engage said first and second rollers in pressure contact with the exposed flanged portions of said supply and take-up reels, respectively, to transmit a rotating motion of said idler member to the selected one of said supply and take-up reels.

Claim 5

The apparatus according to claim 2, further comprising: further openings formed in a side wall of said cassette body opposite the first mentioned side wall; a second arm connected to said sliding lever and mounted for rotation about a central axial point; third and fourth friction rollers mounted on opposite end portions of said second arm; said first and second arms being interlocked with each other through said sliding lever such that when one of said first and second rollers is selectively engaged with its associated reel, a corresponding one of said third and fourth rollers is engaged with the other reel.
