The large pulley 4 also rotates via the belt 50. At this time, the cylinder 56 rotates together with the horizontal shaft 47, and the barbs on its outer circumference repel the vibration valve. As a result, a melody is played from the music box 55.
This melody becomes a beautiful melody when the rotors 19 and 20, which will be described later, are rotating normally, but when the rotors 19 and 20 are rotating abnormally (rotating too fast or too slowly), it becomes an abnormal sound (a sound that does not resemble music). becomes. Therefore, it is possible to know whether the rotors 19, 20 are rotating normally, that is, whether the food is being formed correctly, by the sound emitted by the music box.
By adjusting the rotation speed, accurate molding can be performed at all times.

Therefore, in the state shown in FIG. 4 in which the recess 25 of the rotor 19 and the recess 27 of the rotor 20 are separated on the rollers 14 and 15 side, the container 60 is filled with unformed food, that is, cooked rice, and a portion of it is is manually dropped from the food supply hole 61 between the rollers 14 and 15. Furthermore, when the handle 42 is continued to be turned, the rice is forcibly sent downward by the teeth 18 of the rollers 14 and 15, and is fed between the recesses 25 and 27. Furthermore, as the handle 42 rotates, the recess 2
As 5 and 27 move towards the opposing state, the rice becomes compressed,
When the recesses 25 and 27 face each other as shown in FIG. 5, the rice is most compressed and formed into a sushi shape. When the handle 42 is further turned, the recesses 25 and 27 are separated from each other on the turntable 52 side, and from between these recesses 25 and 27, sushi balls shaped like a nigiri sushi are sequentially placed on the rotating turntable 52 in a circular manner. Discharge them so that they line up in the circumferential direction. When this operation is repeated with a plate placed on the turntable 52, the sushi balls are arranged on the plate.

According to this embodiment, since it does not require power such as a motor and has a simple structure, it can be downsized, and food such as sushi and rice balls can be easily formed at home and automatically placed on a plate. can be arranged in Further, since the container 60, the front lid 6, and the guide body 11 can be easily attached and detached, it is easy to clean before and after use, which is sanitary.

In addition, in the embodiment, the rotors 19, 2
