And the abdominal bone present on the inner wall of the abdominal cavity is approximately the width of the vertebral column and parallel to the middle bone
A pair of restraining members that correct the abdomen, a thin blade that cuts the abdomen along the corrected abdomen to separate the abdomen from the body , and a pair of cut members that cut along the middle bone to the back to remove the middle bone. It has a configuration that includes a thin blade that is separated from the body.
It

[0006]

The above-described method and apparatus of the present invention, as shown in FIG. 1 , inserts the target fish into the abdominal cavity of the fish body that has been pretreated for visceral removal.
Insert a flat plate slightly thinner than the spinal column so that it is parallel to the midbone
The fish is supported on this flat plate. And the abdomen of the fish body
Pressed against the flat plate by a pair of restraining members arranged on the outside.
Then, the inner wall of the abdominal cavity adheres to both sides of the flat plate,
The abdomen that exists in the part is almost parallel to the midbone with the width of the vertebral column
Because it is corrected to each, each of the fish body shown in Figure 4 by a, b, c, d
Even if the cross-sectional shapes of the parts are different as shown in FIG. 5, the shape of the abdominal bone is made uniform by the above-described correction action, and even when the fish body is bent, it is straightened.

Therefore , when a pair of thin blades are cut into the abdomen on both sides along the outside of the abdomen and a pair of thin blades are cut in the back along both sides of the spine, the body of the abdomen and the abdomen are cut. Since the middle bone and the body of the back are separated by the knife, three pieces of fish are cut into one piece with the middle bone and the spine and the abdomen connected and left, and two pieces on both sides without bones at all. Are completed in one place at the same time,
Along with the abdomen and the dorsal midbone,
Bone carving has the highest yield because the body attached to the bone is scarce.
It is something that can be obtained.
