Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
172 words
A driving device for a tape recorder wherein a capstan shaft and a pair of reel shafts for taking up and rewinding a tape are driven and rotated by a motor, comprising a flywheel which is fixed to the capstan shaft and which rotates unitarily with said capstan shaft, means for transmitting power from the motor to said capstan shaft through said flywheel, a rocking bracket which is turnably mounted on an outer periphery of said capstan shaft, two transmission rollers which are disposed on said rocking bracket in a manner to be rotatable on their respective axes, a belt which is extended over said two transmission rollers, a pulley which is fixed to said capstan shaft and on which an outside surface of said belt is laid, the pair of reel shafts being disposed in a position where either of said two transmission rollers impinges on the corresponding reel shaft when said rocking bracket has turned, and means provided on said transmission rollers and for transmitting power to said reel shafts.
Claim 2
Dependent Claim
172 words
A driving device for a tape recorder wherein a capstan shaft and a pair of reel shafts for taking up and rewinding a tape are driven and rotated by a motor, comprising a flywheel which is fixed to the capstan shaft and which rotates unitarily with said capstan shaft, means for transmitting power from the motor to said capstan shaft through said flywheel, a rocking bracket which is turnably mounted on an outer periphery of said capstan shaft, two transmission rollers which are disposed on said rocking bracket in a manner to be rotatable on their respective axes, a belt which is extended over said two transmission rollers, a pulley which is fixed to said capstan shaft and on which an outside surface of said belt is laid, the pair of reel shafts being disposed in a position where either of said two transmission rollers impinges on the corresponding reel shaft when said rocking bracket has turned, and means provided on said transmission rollers and for transmitting power to said reel shafts.
Claim 3
Dependent Claim
57 words
A driving device for a tape recorder as defined in claim 1, in which said pair of reel shafts are formed with gears, and said two transmission rollers are formed with toothed wheels, so that when said rocking bracket has turned, the toothed wheels of said transmission rollers selectively mesh with the gears of said reel shafts.
Claim 4
Dependent Claim
69 words
A driving device for a tape recorder as defined in claim 1, in which said pair of reel shafts are formed with rollers, and bands of rubber are wound round said two transmission rollers, so that when said rocking bracket has turned, the rubber bands of said transmission rollers selectively come into pressed contact with the rollers of said reel shafts so as to frictionally transmit a turning force.
