  • Recording and/or reproducing apparatus including a reel disc having magnetically acting holding means for a reel
    Patent number: 6508427
    Abstract: A recording and/or reproducing apparatus (1) can hold a magnetic-tape cassette (2), which accommodates a supply reel (3) including a first magnetic circuit element (42) and has a disc-shaped drive member (47) including a second magnetic circuit element (49), the two magnetic circuit elements (42, 49) forming magnetically acting holding means (43) for holding the supply reel (3) in the apparatus (1) and the disc-shaped drive member (47) having magnetic-force-of-attraction limiting means (51) which serve to and are adapted to cooperate with the first magnetic circuit element (42) and which enable the magnetic force of attraction produced between the two magnetic circuit elements (42, 49) to be limited.
    Type: Grant
    Filed: February 21, 2001
    Date of Patent: January 21, 2003
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Heimo Huettenegger, Franz Kletzl
  • Recording and/or reproducing apparatus including a reel disc having a magnetic circuit element and drive teeth realized by insert-molding
    Patent number: 6491247
    Abstract: In a recording and/or reproducing apparatus (1) having a reel drive device (35) with a drive shaft (46A) and with a disc-shaped drive member (47) made of a plastic and with drive teeth (48), and with a second magnetic circuit element (49), and with a third magnetic circuit element (50), which is connected to the drive member (47) by insert-molding of the third magnetic circuit element (50), the drive shaft (46A) is connected directly to the third magnetic circuit element (50) in a rotationally interlocked manner and the third magnetic circuit element (50) is formed by an element which is finished by means of a turning operation, and the third magnetic circuit element (50) is dimensioned in such a manner with respect to the drive member (47) that the third magnetic circuit element (50) is not subjected to any deformation by the drive member (47) made by insert-molding.
