<p>PURPOSE:To eliminate the need of a guide rail member and to simplify an automatic loading configuration by controlling Z-axial movement of a loading base freely ascendibly and descendibly borne by a loading ring, etc., via a cam groove. CONSTITUTION:The loading base 36 mounted with a loading guide and borne freely ascendibly and descendibly by guide shafts 32 and 34 of the loading ring 30 is turned integrally with the ring 30. In this case, the base 36 is regulated in a lower part than a lead part of a tape guide band of a rotary head 20 or in the Z-axial movement by the cam groove 22A provided on a drum base 22 for the drum 20, so that the need of a complicated guide rail member for regulating three-dimensional movement is eliminated, and the automatic loading device configuration is simplified.</p> |
