  • Patent number: 9106110
    Abstract: A power generating device includes a power generating part, a sliding member, first, second and third elastic parts, and a connecting member. When the sliding member is caused to move to a first storage completion position by an operation that causes the connecting member to rotate, the connecting member and the sliding member are disconnected so that the sliding member is caused to move in a first direction by an elastic force stored in the second elastic part. The connecting member is caused to rotate by an elastic force stored in the third elastic part. When the sliding member is caused to move to a second storage completion position by the third elastic part, the connecting member and the sliding member are disconnected so that the sliding member is caused to move in a second direction by an elastic force stored in the first elastic part.

  • Patent number: 5758835
    Abstract: A magnetic tape apparatus includes a head which reproduces data from or records data onto a magnetic tape, taken out from a cassette, when the tape is running. A supply reel shaft rotates a supply reel to supply the tape from the cassette to the head. A take-up reel shaft rotates a take-up reel to wind the tape from the head around the take-up reel. A back tension applying mechanism has a brake part which presses the supply reel shaft to produce a braking force on the supply reel shaft, the back tension applying mechanism applying a back tension to the tape when the braking force is produced. A pressing force varying mechanism controls a pressing force of the brake part on the supply reel shaft such that the pressing force is maintained at an appropriate level for a type of cassette.
