Abstract
Abstract Apparatus including a magnetic tape (4) having transparent lead tapes connected at both ends thereof which extends between a feed reel (2) and a take-up reel (3) in a cassette (1); a light receiving element (36) is incorporated into a positioning pole (7) located in said cassette (1) when the cassette (1) is in an operative position, whereas a light emitting element (38) is provided outside the cassette (1) at a point opposite to said light receiving element (36) and across said magnetic tape (4) interlaid between these two elements (36, 38). In this way, the two elements (36,38) are adapted to detect the lead tape at the end of said magnetic tape (4).

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
139 words
Apparatus for a cassette recorder for detecting the end of magnetic tape (4) having transparent lead tapes (9) connected at both ends thereof, which tape (4) extends between a feed reel (2) and a take-up reel (3) of a cassette (1), characterized in that the apparatus includes one of a light receiving or a light emitting element (36, 38) located in said cassette (1) when the cassette (1)is in an operative position and the other of a light emitting or a light receiving element (38, 36) located on the apparatus outside the cassette (1), the magnetic tape (4) interrupting the light path between the two elements (36, 38), the arrangement being such that the light path is restored when a lead tape (9) enters the light path to thereby provide an indication of the end of the tape (4).
Claim 2
Dependent Claim
139 words
Apparatus for a cassette recorder for detecting the end of magnetic tape (4) having transparent lead tapes (9) connected at both ends thereof, which tape (4) extends between a feed reel (2) and a take-up reel (3) of a cassette (1), characterized in that the apparatus includes one of a light receiving or a light emitting element (36, 38) located in said cassette (1) when the cassette (1)is in an operative position and the other of a light emitting or a light receiving element (38, 36) located on the apparatus outside the cassette (1), the magnetic tape (4) interrupting the light path between the two elements (36, 38), the arrangement being such that the light path is restored when a lead tape (9) enters the light path to thereby provide an indication of the end of the tape (4).
Claim 3
Dependent Claim
24 words
Apparatus as claimed in claim 1:,. characterized in that said indication is used to initiate operation of a stop mechanism to stop tape transport.
Claim 4
Dependent Claim
46 words
Apparatus as claimed in claim 1 or 2, characterized in that said one of the elements (36, 38) is located in a positioning pole (7) mounted on the apparatus and serving also to locate the cassette (1) when the cassette (1) is in an operative position.
Claim 5
Dependent Claim
81 words
Apparatus as claimed in claim 3 further including a receiving plate (5) on which the cassette (1) is locatable, the receiving plate (5) being pivotable to locate on a base table (6) to thereby locate the cassette (1) in the operative position, the base table (6) having secured thereto a U-shaped mounting piece (33), one of the limbs of which comprises said positioning pole (7), the other limb comprising an upstanding portion (33a) carrying the other of said elements (36, 38).
Claim 6
Dependent Claim
49 words
Apparatus as claimed in claim 3 or 4, characterized in that two positioning poles (7) are provided each carrying one of the elements (36, 38) and being associated with a respective other element (38, 36) to thereby provide indications of the end of respective ends of the tape (4).
