2. Description of the Related Art A fish has a vertebra and a myriad of small ribs, which hinders the cooking and eating of the fish. For this reason, various proposals have been made. . For example, Japanese Patent Application Laid-Open No. 6-253725 discloses the following proposal. In the above proposal, after removing the visceral part including the intestine and the gill, the tail end is cut from the vertebra, and then a long special spatula is manually inserted from the oral cavity or the operculum to peel off the vertebrae from the meat part. The two sides of the fish are alternately performed. In addition, special fair 5
In the invention described in Japanese Patent Application Publication No. 20053, also in the washed fish body from which the gills were taken out, after cutting the base of the tail and the base of the head of the vertebra, the basal spatula was used to remove the vertebrae from the abdominal cavity one side at a time. The vertebrae and the flesh are peeled off while being pushed along, and the treatment is performed manually. There are also mechanical treatments for the manual separation of the bone and the meat, but in these conventional three-sheet wholesalers, the processing is mainly performed using only round blades. The yield is very poor, and a large amount of body remains on the abdomen on the abdomen, and it is difficult to remove three bones and ribs, including the ribs, at a high yield.
