Slicers used for slicing and cutting into shapes are known.

In the art, there have been efforts and researches to integrate the functions of food processors having different functions as described above. For example, Applicant has developed a juicer / mixer combined food processor that incorporates the functions of a juicer and a blender. Such a juicer / mixer combined food processor includes a juicer module and a mixer module that are detachably mounted on a body incorporating a drive means. Thus, the user was able to use both functions, a mixer (or grinding) function and a juicer function, by replacing the juicer module or mixer module. However, the food processor as described above has a fixed speed (RPM) of the drive means built in the body due to the food processing characteristics of the blender or juicer, for example, by rotating the blade at a low speed of about 1500rpm, such as vegetables, fruits, etc. There was a limit to integrating the slicer's ability to slice and cut food.
