The upper wall itself of the cover body is formed in a concave shape that is recessed downward so as to be an inclined surface to be transferred .
Further, it is preferable that the rear inclined surface is steeper than the front inclined surface of the upper surface of the cover body.

  According to the present invention, since the upper surface of the cover body is formed in a concave shape that is recessed downward, even when a plurality of packed rice is stacked on the upper surface of the cover body, the packed rice can be stably placed on the upper surface of the cover body. It is also possible to prevent the packed rice placed on the upper surface of the cover body from moving together when the packed rice on the upper surface of the cover body is taken out by dragging.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

When the detector 72 detects the detected member 71, a detection signal is sent to the control device 68. When the stirring device 6 is stopped by a stop signal from the control device 68, the detector 72 is detected. The stirring device 6 is set to stop based on the detection signal of the detected member 71 sent from the control device 68 to the control device 68.
In the present embodiment, as shown in FIG. 7, when the fourth stirring rod A4 having the shortest recumbent portion 66 is positioned on the front side among the first to fourth stirring rods A1 to A4, the stirring device 6 is configured to stop.

When the stirring rod A is stopped, the recumbent portion 66 of the fourth stirring rod A4 does not have to face directly in front, and is slightly left and right as shown in FIGS. The long stirring rods A1 and A2 of the recumbent portion 66 need only be hidden under the case 3, and the long recumbent portion of the long stirring rods A1 and A2 of the recumbent portion 66 may be shifted. The extended end side of 66 may protrude slightly below the rice inlet 22, and the horizontal bar 66 of the long stirring rods A <b> 1 and A <b> 2 of the horizontal bar 66 is a hindrance to the rice input of packed rice P It only has to be such that it does not become.
In addition, when the stirring rod A is stopped, it is not always necessary to stop the stirring rod A4 having the short rib portion 66 so that the stirring rod A4 is positioned on the front side (for example, when the stirring rod A is stopped in the middle of washing the rice). When the stirring device 6 is stopped at the final stage from the start of stirring to the removal of rice, the short stirring rod A4 of the recumbent portion 66 is stopped on the front side. What is necessary is just to be comprised (that is, it should just be comprised so that the short stirring rod A of the horizontal reed part 66 may be located in the lower side of the rice insertion port 22 when the packed rice P is thrown in).

Further, when the stirring rod A3 of the second short recumbent portion 66 does not become an obstacle to the introduction of the packed rice P, the stirring rod A3 of the second short recumbent portion 66 is placed below the rice input port 22. You may make it stop.
In addition, the stirrer bar A4 of the shortest horizontal paddle part 66 and the stirrer bar A3 of the second shortest horizontal paddle part 66 are arranged next to each other in the circumferential direction of the rotary shaft 61, and they interfere with the introduction of packed rice P You may make it stop in the position which does not become and the lower position of the rice insertion slot 22.
