DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fish lowering device for dividing a fish body and a bone into two or three pieces with a kitchen knife.

[0002]

BACKGROUND OF THE INVENTION Generally, when lowering fish in a home or a small fish store, the fish is put on a cutting board and cut off with a kitchen knife or the like. Especially when lowering fish, first scrape the scale, cut off the head, and take out the internal part of the abdomen.
The remaining fish are placed on a cutting board with the length of the fish facing sideways. Next, while holding the fish body by hand, the kitchen knife or the like is moved from the head side along the upper surface of the medial bone so that the body does not remain at the medial bone, and the upper body portion is cut off. A method of turning the remaining body upside down and moving a blade of a kitchen knife or the like along the upper surface of the middle bone to separate the lower body and the middle bone to lower the fish is also used.

[0003]

However, in order to reduce the fish to three pieces by the conventional method, for example, the fish is cut into three pieces of the upper body, the middle bone, and the lower body, and the fish is divided into a body and a bone part. Although it is necessary to ensure that no residue remains, this operation requires skilled and specialized skills, and it has not been possible for an unskilled person to easily perform the lowering operation. In addition, the fish lowering operation itself is performed with the hand holding the fish by hand, so it is difficult to lower the fish easily and in a short time. In addition, when an unskilled or unskilled person lowers the fish, the yield is deteriorated, and the fish cannot be judged to be worthy of use.

[0004] The present invention has been made in view of the above-mentioned conventional problems, and one object of the present invention is to provide a fish lowering apparatus that allows even an unskilled person to easily perform the lowering operation when lowering the fish. Another object of the present invention is to provide a fish lowering device which can easily and quickly judge a fish body by holding the fish body and eliminating a shift in a vertical and horizontal direction when the fish body is judged. Another object of the present invention is to provide a fish lowering device which efficiently separates a body and a bone portion of a fish body only by sliding a horizontal blade when separating the fish body, thereby improving a yield.

[0005]
