Abstract
PURPOSE:To avoid ineffective holding of main trunk for a long time, by starting recording only when a start switch is operated within a specified time after the opertion of a recording switch. CONSTITUTION:A bell signal is received at a bell receiving circuit 2, and the output is at level 1. The signal of this level 1 is inputted to OR circuit OR1, OR2 and level 1 is respectively outputted at the output. When when the output of the OR circuits OR1 is at level 1, a transistor (TR)Q1 is conductive, and a motor 11 and a magnet 12 are respectively operated to run a tape 5. When the output of the OR circuit OR2 is at level 1, the TRQ2 is conductive and a relay Y is operated. The relay Y, motor 11 and magnet 12 keep operation while the tape 5 circulates until the tape comes to a start position and passes through the position, by means of the output of level 1 of a slow restoration circuit 13 and after passing through it, by means of the output of level 1 of a NOT circuit INV1.
