<p>PURPOSE:To simplify the construction and to reduce the assembling cost, by constituting a means for giving screwing force to a slide body mounting guide rollers with a screw constructing body made of a flexible resin provided with screw grooves at the external circumference and with its rotating means. CONSTITUTION:Screw constructing bodies 32a and 32b are contained in guide grooves 33a and 33b of a chassis 31, and mounting parts 34a and 34b of sliding bodies 30a and 30b are mounted on grooves 32'a and 32'b of the bodies 32a and 32b. The sliding bodies 30a and 30b are advanced with screwing force through the rotation of the bodies 32a and 32b, a magnetic tape 44 is drawn out from a cassette 43 with guide rollers 28a and 28b and tilted guides 29a and 29b and loaded on a cylinder 24. With such constitution, the constitution can be simplified, the number of components can be reduced and the assembling cost can be decreased than conventional systems.</p> |
