Abstract

678,358. Magnetic recording apparatus. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. March 14, 1951. [June 12, 1950] No. 6119/51. Addition to 678,133. Class 40 (ii). In an apparatus as in the parent Specification, the take-up controller comprises an auxiliary device which periodically tensions the band. During rotation of the take-up spool 5, a wheel 123, mechanically coupled thereto, rotates until a switch-carrying member 12 is lowered on to the band 1 under the influence of a spring 121. The resulting tension in the band produces a pressure on the press button 126 of the switch 127 which is opened so that an electro-magnetic coupling between a driving motor and the spool 5 is broken until the tension in the band has slackened sufficiently for the switch 127 to close again. The closing of switch 127 starts the spool 5 and wheel 123 rotating again so that the member 12 is lifted away from the tape by means of the link 125.
