Abstract:
A recording and/or reproducing apparatus (1)adapted to hold a cassette (2) which includes a supply reel (3) which is rotationally drivable with respect to a reel axis (3A), which supply reel serves to and is adapted to take up a record carrier (4) in the form of a tape and which is connected to a reel-side reel drive means (41) and which is connected to a first magnetic circuit element (42), which magnetic circuit element serves to form magnetically acting holding means (43) for holding the supply reel (3) in the recording and/or reproducing apparatus (1), and having a reel drive device (35) for rotationally driving the supply reel (3), which reel drive device (35) has a disc-shaped drive member (47), which is rotationally drivable with respect to a disc axis (46), which drive member (47) has a drive-member-side reel drive means (48), which means serves to and is adapted to cooperate in a driving fashion with the reel-side reel drive means (41), and which drive member (47) is connected to a second magnetic circuit element (49), which serves to form the magnetically acting holding means (43) for holding the supply reel (3) in the recording and/or reproducing apparatus (1), characterized in that the disc-shaped drive member (47) has magnetic-force-of-attraction limiting means (51), and the magnetic-force-of-attraction limiting means (51) serve to and are adapted to cooperate with the first magnetic circuit element (42) of the supply reel (3), and the magnetic-force-of-attraction limiting means (51) enable the magnetic force of attraction produced between the first magnetic circuit element (42) and the second magnetic circuit element (49) to be limited to a given value, wherein the second magnetic circuit element (49) is formed by an annular magnet, and a third magnetic circuit element (50), which is also annular and also forms a magnetic yoke, is connected to the disc-shaped drive member (47).
