Abstract

PURPOSE:To diversify the function of a player, by uniting pinch rollers and an erasing head to one body and bringing into contact with tape surface from one window. CONSTITUTION:Three types of pinch rollers 20-22 consists of a rubber layer 2 and a magnetizing enable layer 10, each layer 10 is an electromagnet and erases the information on tape, which is magnetized as required. The pinch rollers 20-22 are for 1, 2, 4 tracks respectively. The diameter of the rubber layer 2 is slightly greater than that of the layer 10. The layer 10 has a plurality of poles 11, and a wire 11a is wound independently by taking the poles opposed as a pair, and slipping according to the number of poles are sectioned and both ends 11a', 11a'' of the wire 11a are connected to an opposing pair of slipping segments. When the pinch rollers contact a tape and turn, a pair of slipping segments contact brushes 11b', 11b'' to magnetize only the pole in contact with the tape. Thus, the function of a player can be diversified.
