PURPOSE:To inform that a device arrives at a track which cannot be reproduced by giving the alarm through the operation of a reverse switch in the midst of reproducing the 1st track, or through the operation of a forward switch in the midst of reproducing a final track. CONSTITUTION:A signal SF which is generated when contents in final track memory are equal to a reproduction track position and the on-signal of a forward switch are inputted to an AND gate 80. When both of them are at 'H' level, a signal at 'H' level is outputted from the AND gate 80. A signal SS outputted in the midst of reproducing the 1st track and the signal when the reverse switch is turned on are inputted to an AND gate 82. When both of them are at 'H' level, a signal at 'H' level is generated. Outputs of the gates 80 and 82 are inputted to a flickering circuit 86 through an OR gate 84, and the alarm is given with a display output. |
