Abstract
Abstract A recording and/or reproducing apparatus performs recording and/or reproduction with a tape cassette having a cassette case and a supply side reel and a take-up side reel provided within the cassette case for winding a tape. The recording and/or reproducing apparatus comprises a reel driving shaft relatively entering from the bottom of the cassette case to engage with a center part of one reel of the supply side and take-up side reels when the tape cassette is loaded into a predetermined position of the recording and/or reproducing apparatus, to rotate the one reel, and a rotation transmitting mechanism for engaging with a part of the other reel, at a part other than a center part thereof, to rotate the other reel.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
140 words
A recording and/or reproducing apparatus for recording and/or reproduction when loaded with a tape cassette having a cassette case including a supply side reel and a take-up side reel for winding a tape, said recording and/or reproducing apparatus comprising: a reel driving shaft for relatively entering the bottom of said cassette case to engage a center part of and rotate one of said reels when said tape cassette is loaded into a predetermined position within said recording and/or reproducing apparatus; a rotation transmitting means for engaging a part of and rotating the other of said reels, with said engaging part being at a part other than a center part thereof; and means for alternatively driving the reel driving shaft and the rotation transmitting means in a direction in which said one reel and the other reel alternatively wind the tape.
Claim 2
Dependent Claim
140 words
A recording and/or reproducing apparatus for recording and/or reproduction when loaded with a tape cassette having a cassette case including a supply side reel and a take-up side reel for winding a tape, said recording and/or reproducing apparatus comprising: a reel driving shaft for relatively entering the bottom of said cassette case to engage a center part of and rotate one of said reels when said tape cassette is loaded into a predetermined position within said recording and/or reproducing apparatus; a rotation transmitting means for engaging a part of and rotating the other of said reels, with said engaging part being at a part other than a center part thereof; and means for alternatively driving the reel driving shaft and the rotation transmitting means in a direction in which said one reel and the other reel alternatively wind the tape.
Claim 3
Dependent Claim
35 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said reel driving shaft engages with the supply side reel, and said rotation transmitting mechanism is constructed to rotate the take-up side reel.
Claim 4
Dependent Claim
71 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said tape cassette is smaller than a standard type tape cassette which is constructed to be loaded into a standard type recording and/or reproducing apparatus to perform recording and/or reproduction, and said recording and/or reproducing apparatus has a tape cassette loading part which is smaller than a tape cassette loading part of said standard type recording and/or reproducing apparatus.
Claim 5
Dependent Claim
31 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said rotation transmitting mechanism transmits rotation to an outer peripheral part of a reel flange in said other reel.
Claim 6
Dependent Claim
52 words
A recording and/or reproducing apparatus as claimed in claim 4 in which said reel flange of said other reel has a gear part formed at the outer peripheral part thereof, and said rotation transmitting mechanism has a gear wheel for meshing with the gear part of said reel flange to transmit rotation.
Claim 7
Dependent Claim
43 words
A recording and/or reproducing apparatus as claimed in claim 4 in which said other reel has an upper reel flange and a lower reel flange, and said rotation transmitting mechanism is constructed to transmit rotation to the lower flange of said other reel.
Claim 8
Dependent Claim
50 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said other reel unitarily has a gear part having a diameter which is smaller than the diameter of its own reel flange, and said rotation transmitting mechanism has a gear wheel to transmit rotation to said gear part.
Claim 9
Dependent Claim
37 words
A recording and/or reproducing apparatus as claimed in claim 7 in which idler gears are provided with said cassette case, and the rotation of said gear wheel is transmitted to said gear part through said idler gears.
Claim 10
Dependent Claim
64 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said other reel has a gear wheel which rotates unitarily with said other reel, said rotation transmitting mechanism has a gear wheel for meshing with said gear part to transmit rotation, and each tooth of at least one of said gear wheels has a tapered surface formed at the upper part thereof.
Claim 11
Dependent Claim
102 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said tape cassette has a braking member for performing a braking action with respect to the other reel when urged downwards to make contact with a peripheral part of said other reel, and for releasing the braking action with respect to said other reel when moved upwards to depart from the peripheral part of said other reel, and said recording and/or reproducing apparatus has a raising member which is relatively inserted within said cassette case when said tape cassette is loaded into the predetermined position to raise said braking member.
Claim 12
Dependent Claim
64 words
A recording and/or reproducing apparatus as claimed in claim 10 in which said cassette case of said tape cassette is provided with a hole in the bottom thereof at a position opposing said braking member, and said raising member consists of a pin-shaped member for relatively entering into the hole in said cassette case to make contact with and push said braking member upwards.
Claim 13
Dependent Claim
89 words
A recording and/or reproducing apparatus as claimed in claim 11 in which said cassette case of said tape cassette is further provided with another hole in the bottom making a pair with said hole, said recording and/or reproducing apparatus is further provided with another pin-shaped member forming a pair with said pin-shaped member, and said pair of pin-shaped members relatively enter into said pair of holes in said cassette case when said tape cassette is loaded into the predetermined position, to locate said cassette case to said predetermined position.
Claim 14
Dependent Claim
71 words
A recording and/or reproducing apparatus as claimed in claim 1 in which said rotation transmitting mechanism comprises a rotary body for transmitting rotation to said other reel, and a moving mechanism for moving said rotary body from a position for not transmitting rotation to said other reel to a position for transmitting rotation to said other reel, in relation to the loading operation of said tape cassette into said predetermined position.
Claim 15
Dependent Claim
79 words
A recording and/or reproducing apparatus as claimed in claim 13 in which said moving mechanism comprises urging means for urging said rotary body to move towards the position for transmitting rotation to said other reel, holding means for locking said rotary body against the urging force of said urging means so that said rotary body does not move, and means for releasing the holding operation in relation to the loading operation of said tape cassette into said predetermined position.
Claim 16
Dependent Claim
