<p>A food processor is comprised of a food processing cutter which is driven by a motor (19) connected to an AC power source (28), a switch (29) for controlling on and off of the motor, a pulse generator (30) for forming count pulses (Pc) having a given period from the AC power source, a set switch (33), a start switch (37), and a timer (49) which operates the start swich (37) at a time point set therein to start the rotation of the motor (19). Further, the food processor includes an up-counter (35) for counting the count pulses (Pc) while the set switch (33) is operated to store a driving time period data of the motor (19), and a down-counter (39) to which the stored data of the up-counter (35) is transferred when the start switch (37) is operated by the timer (49). The down-counter (39) counts down the data every time it receives the count pulse and produces a drive stop signal for the motor (19) when Its contents become «0».</p> |
