Abstract
In a magnetic recording and/or reproducing apparatus of the type having a cylindrical tape guide drum with at least one rotary magnetic head adapted to move in a circular path substantially coinciding with the outer circumferential surface of said drum and a tape cassette holder positioned in front of the guide drum for receiving a tape cassette containing a magnetic tape, an automatic tape loading and unloading device for wrapping a portion of the tape about the guide drum includes a rotatable support ring extending around the guide drum and being rotatable in a plane that is inclined with respect to a plane passing through the tape in the tape cassette; a tape drawing mechanism for withdrawing a loop of tape from the cassette to a predetermined position adjacent the guide drum; a first tape guiding assembly adapted to ride along an arcuate guide rail surrounding a first portion of the outer circumferential surface of the guide drum and actuable by a guide pin on the support ring for wrapping the loop of tape about the first portion of the outer circumferential surface of the tape guide drum as the support ring rotates thereabout; and a second tape guiding assembly including a tape engaging pin mounted on the support ring for successively wrapping the loop of tape about a contiguous second portion of the outer circumferential surface of said tape guide drum upon completion of operation of the first tape guiding assembly.
