<p>PURPOSE:To reduce the number of parts and to apply a tape loading device to any loading route by executing the sliding motion of a lead screw along a guide means with the revolving shaft of a driving wheel as a center while a moving member is moved in the axial direction of the lead screw. CONSTITUTION:A lead screw 15 is meshed with a slave bevel gear 13, which is a slave wheel, in an edge part. A driving bevel gear 11 is engaged to a pin 40, which is planted in a mechanism chassis 41 of a magnetic recording and reproducing device, with being freely revolvable and supported by an arm 32, which is a supporting member, in the outer circumference direction of the slave bevel gear 13 and pin 40 with being freely revolvable. A claw 33 of a moving member 19 is engaged to the lead groove of the lead screw 15 and a roller post 17, which is the guide member, is vertically planted on the moving member 19 so as to be slided with the mechanism chassis 41. Thus, the number of the parts is reduced and tape loading can be executed along the arbitrary loading route.</p> |
