Abstract
Abstract A cassette adapter comprises, essentially, a cartridge-shaped casing for containing a tape cassette, a tape driving pinch roller driven by rotating force transmitted thereto from a rotating capstan on the side of the tape driving device of the cartridge playing apparatus, and a fixed pin or stud for projecting into the cassette thus contained. The fixed pin thus inserted takes a position on the inner side of the tape installed in the cassette. The driving pinch roller, which is made thinner than the width of the tape and rotates positively, presses against the fixed pin only over the tape interposed therebetween and thus drives the tape by friction between it and the tape.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
272 words
A tape cassette adapter cooperating with a tape cartridge player and comprising: a casing having a recessed part for accommodating therein a tape cassette and having an exterior shape and dimensions similar to those of a standard tape cartridge; a first pinch roller means having no flywheel and disposed in said casing so as to press against a rotating capstan means mounted in the tape cartridge player when said casing is inserted into a predetermined loading position within the tape cartridge player, so that said first pinch roller means is rotated by the capstan; a fixed pin means fixedly connected to said casing and projecting into said recessed part so as to cooperatively fit into said tape cassette and be positioned on the inner side of a tape installed therein when the tape cassette is accommodated in said recessed part, said fixed pin means having a smooth planar part which opposes a surface of the tape; a second pinch roller means having no flywheel and frictionally associated with the smooth planar part of said fixed pin and having the tape interposed therebetween so that the tape is driven by frictional force between the tape and said second pinch roller means; an endless belt of a non-stretching and non-contracting nature stretched between said first and second pinch roller means; a magnetic head for recording a signal on the tape and for reproducing a signal from the tape; coupling means for transferring the signal between said magnetic head and the tape cartridge player; and a means for causing said second pinch roller means and said magnetic head to contact the tape and separate therefrom.

Claim 3
Dependent Claim
53 words
The tape cassette adapter as defined in 1 wherein the thickness of said second pinch roller means in the axial direction thereof is less than the width of said tape, whereby said second pinch roller means presses against said fixed pin means only over the tape without directly contacting said pin fixed means.
Claim 4
Dependent Claim
53 words
The tape cassette adapter as defined in 1 wherein the thickness of said second pinch roller means in the axial direction thereof is less than the width of said tape, whereby said second pinch roller means presses against said fixed pin means only over the tape without directly contacting said pin fixed means.
Claim 5
Dependent Claim
35 words
The tape cassette adapter as defined in claim 1 further comprising a sleeve of a material of low coefficient of friction closely fitted on and around the outer peripheral surface of said fixed pin means.
Claim 6
Dependent Claim
49 words
The tape cassette adapter as defined in claim 1 wherein the smooth planar part of said fixed pin means has a cutout slot the width of which is formed in the axial direction of said fixed pin means, said width being no less than the width of the tape.
Claim 7
Dependent Claim
141 words
The tape cassette adapter as defined in claim 1 wherein said means for causing said second pinch roller means and the magnetic head to contact the tape and separate thErefrom comprises a pivoted lever rotatably supporting said second pinch roller means and fixedly supporting said magnetic head, means for imparting to said pivoted lever a torque such as to cause said second pinch roller means and said magnetic head to separate from said tape, and rotating means for rotating said pivoted lever in a manner so as to cause said second pinch roller means and said magnetic head to contact said tape, said rotating means being actuated from the side of said casing by a pressing member for casing retention provided in said tape cartridge player when the casing is inserted into the predetermined loading position within the tape cartridge player.
Claim 8
Dependent Claim
144 words
The tape cassette adapter as defined in claim 5 further comprising an amplifier circuit for amplifying signals reproduced by said magnetic head; and wherein said coupling means includes a coupling magnetic head caused to contact with a second magnetic head disposed in said tape cartridge player when the casing is inserted into the predetermined loading position, said coupling magnetic head transmitting to said second magnetic head the output signals of said amplifier circuit; an electric power source for operating said amplifier circuit; and switch means responsive to the pivotal rotation of said pivoted lever for opening and closing an electrical connection between said electric power source and said amplifier circuit, said switch means being adapted to close said electrical connection when said pivoted lever pivotally rotates in a manner to cause said second pinch roller means and said magnetic head to contact said tape.
