よりアーム(20)。Next, the operation will be explained. The members indicated by two-dot chain lines in FIGS. 6 and 7 are in the first position where the magnetic tape (5) in the tape cassette (4) can be pulled out, that is, before loading, and are indicated by solid lines. The loaded member is at the second position where the magnetic tape (5) is pulled out of the tape cassette (4) and attached to the magnetic head (6), that is, when loading is completed. ”
When bl, N erogiing starts, the loading motor (not shown) is driven, and its rotational force is transferred to the drive gear (
36), and the main cam (31) moves in the direction of the arrow (100
) direction. Following this movement, the arm (
34) rotates in the direction of arrow (101), and the lower reciprocating member (24) moves in the direction of arrow (102). Then, the rack (29a) formed on the suppressing member (29A)
) e (29b) and the arm (20) by engagement of the gears (18) and (19).

41) rotates in the direction of the arrow (107), and the pin (39)
) resists the biasing force of the pressing bar 4 (43), and the pinch roller (13) attached to the pinch arm (14a) generates pressure against the capstan (3 days). Furthermore, when releasing the attachment between the magnetic head (6) and the magnetic tape (5), the loading motor (not shown) rotates in the opposite direction to that during loading, and the main cam (31) rotates in the opposite direction to the arrow (100). Following this movement, each lever arm and reciprocating member rotate or move in the opposite direction with respect to each arrow, and return to the pre-loading position shown by the two-dot chain line, that is, the first position from which the magnetic tape can be pulled out. Return to position.
