The lever 60 may be provided integrally with the push button 18.
Further, in order to demonstrate the cutting performance of the cutter 20, when the micro switch 63 is turned on by a separate control unit (not shown), the driving unit 16 is driven, for example, for 0.5 seconds to 3 seconds. Thereafter, intermittent driving may be performed so as to be stopped for 0.5 seconds to 3 seconds. The drive time / stop time is not particularly limited. By performing such control, particularly when cooking meat, the blade of the cutter can be cut into the meat and then pulled out.

The food processor 10 according to the present embodiment is configured as described above.
As described above, as shown in FIG. 2, the food processor 10 assembles the cutter 20, the cover 14, and the drive unit 16 into the container 12, and the coupling member 33 on the container side is coupled to the coupling on the drive unit side. If it is not in the state of being fitted into the fitting hole 53 of the gear 49 as a member, the cutter 20 is not rotated even if the push button 18 is pushed, and safety is improved. That is, even if the cutter 20 is mistakenly assembled to the assembly in which the cover 14 and the drive unit 16 are assembled as shown in FIG. 8, the coupling member 33 of the cutter 20 is placed in the cylindrical base 28. Since it is in the state of being immersed, the cutter 20 cannot be assembled | attached to the said assembly in the first place. Further, since the fitting hole 53 of the gear 49 serving as the coupling member on the drive unit side is closed by the cover member 55, the safety is further improved. Since the cover member 55 closes the fitting hole 53, the cover member 55 also has a function of preventing vegetable chips and the like from entering the fitting hole 53.
On the other hand, as described above, in the state of the drive unit 16 alone, the micro switch 63 does not enter the state when the push button 18 is pressed, and safety is also taken into consideration in this respect.

Of course, the switch is not limited to a micro switch, and other equivalent switches can be used.
In the above embodiment, the cover 14 and the drive unit 16 are provided so as to be separable. However, the cover 14 may be provided integrally with the drive unit 16 so as not to be separable.
