A hatching (10) covering an upper space of a tableware or a plate, and a rotary arm (21) connected to a rotary shaft portion of the hatch, and performs a hatch opening / closing operation. The present invention is characterized in that the opening / closing operation portion 20 for driving the rotary arm 21 is fixedly disposed around the tableware through a fixing arm 22 which is fixed to the table on which the tableware is placed or fixed to the table, By keeping the hatch closed for as long as possible, the user's meal time can be increased. The operation timing of the hatch can be effectively adjusted by the image recognition device 31 attached to the inner surface of the hatch, and a control unit for controlling the opening and closing operation unit 20 to grasp a reduction amount of the food contained in the tableware or the plate. In this process, the difference between the hatch angle when the table is covered and the hatch angle when it is open is a very effective three-dimensional scanning tool that allows the three-dimensional shape difference of the food currently being consumed, A plurality of partial openings 11 are formed in the hatch to prevent a sudden collision between the bottom and the hatch during the meal operation, and the opening and closing operation of the hatch can be easily performed in a state where the bottom is lowered to the edge of the table. The present invention can solve the drawbacks of the conventional eating habit calibration apparatus which can not measure the actual food reduction amount and has no means for controlling the feeding speed.식기 또는 식판의 상부 공간을 덮는 해치(10)와, 해치의 회전축 부위와 연결된 회전암(21)으로 해치의 개폐작동을 수행하는 식습관 교정기와 이를 구비한 식기가 개시된다.본 발명은 식기가 놓여진 테이블에 고정시키거나 또는 식판에 부착 고정시키는 고정암(22)을 통해 회전암(21)을 구동하는 개폐작동부(20)를 식기 둘레에 배치 고정시켜 사용자가 음식물을 씹고 있는 동안 해치를 닫은 상태로 충분히 유지함으로써 사용자의 식사시간을 늘릴 수 있다.해치의 동작타이밍은, 해치 내부면에 부착된 영상인식장치(31)와 이를 통해 식기 또는 식판에 담긴 음식물의 감소량을 파악하고 개폐작동부(20)를 제어하는 제어부에 의해 효과적으로 조정될 수 있다. 이 과정에서 식기를 덮었을 때의 해치각도와 열렸을 때의 해치
