Abstract

PURPOSE: To provide a control circuit, which can be free from chattering, which can have the number of capacitors reduced and which can be easily integrated, by storing the mode converting condition for a preset time with the use of an RS type flip- flop.
CONSTITUTION: If switches 4 to 6 for play, fast forward and rewind are operated, D type FF 48 to 50 are set. RS type FF 51 to 53 are set so that they are not reset even if the FF 48 to 50 are reset for a short time by the chattering. A transistor 57 is rendered inconductive by the set outputs of the FF 51 to 53, which prohibit the mode change of a drive circuit 1 therefor. When a capacitor 60 connected with a resistor 59 is charged to a preset voltage after a preset time lapse, the FF 48 to 50 are reset by a voltage detecting circuit 61, and the FF 51 to 53 are set so that mode change-over solenoids 28 and 29 are energized by the drive circuit 1. As a result, if the switches 4 to 6 are operated to effect the mode change, the change- over control can be accomplished with the use of a circuit which can be free from any chattering and which can be easily integrated with a reduced number of capacitors such as a common delay capacitor.
