PURPOSE:To attain a small and thin structure of a magnetic recorder with simple constitution by controlling the positions of many tape draw-out blocks mounted slidably on a common substrate at a part of the rail of the substrate. CONSTITUTION:The tape draw-out blocks 7 and 8 are guided to slips 16a and 16b of a rail 16 with revolutions of a loading motor and rotated to draw out a tape. The block 7 is fitted slidably to the slit 16a of the rail 16 of a common substrate 7g; while the block 8 is fitted to the slit 16b having a little larger width than the slit 16a. In a loading mode the block 8 is hooked at the inlet of the slit 16a and the block 7 is hooked by a spring core 15. Thus both blocks are positioned. Therefore it is enough to pull only the substrate 7g containing plural tape draw-out blocks. This decreases the number of component parts. Furthermore, a small and thin structure is attained for a magnetic recorder with simple constitution since the rail and the blocks are formed with thin plate type members.
