The purpose of the present invention is to provide a device for testing the performance of a ball detection sensor and a ball hitting device used therefor, which have a very simple structure and enable manufacturing to be carried out at low costs, and allow batting with a wide range of pitches to be carried out in a uniform and repeated manner, and particularly, batting with various spins, which was conventionally difficult to be implemented even with a person's ability or even with mechanical power, can be carried out uniformly and repeatedly. To this end, the ball hitting device, according to one embodiment of the present invention, comprises: an air tank for storing compressed air for generating air pressure; a hitting member which is driven in a linear direction by obtaining a driving force by the air pressure of the compressed air stored in the air tank, and which hits a ball; a cylinder member which has a hollow inside such that the compressed air is applied to the hitting member, and which guides such that the hitting member is driven in the linear direction; and a cylinder rotating device for rotating the cylinder member at a predetermined angle on the basis of the linear direction. La présente invention vise à fournir un dispositif pour tester la performance d'un capteur de détection de balle, et un dispositif de frappe de balle utilisé pour celui-ci, qui ont une structure très simple et permettre une fabrication à de faibles coûts, et permettent à une frappe, ayant une large plage de lancers, d'être réalisée de façon uniforme et répétée et, en particulier, une frappe avec divers effets, qui était habituellement difficile à mettre en œuvre même avec la capacité d'une personne ou une énergie mécanique, peut être réalisée de façon uniforme et répétée. À cet effet, le dispositif de frappe de balle, selon un mode de réalisation de la présente invention, comprend : un réservoir d'air pour stocker l'air comprimé pour générer une pression d'air ; un élément de frappe qui est entraîné dans une direction linéaire en obtenant une force d'entraînement par la pression d'air de l'air comprimé stocké dans le réservoir d'air, et qui frappe une balle ; un élément de cylindre qui a un intérieur creux, de telle sorte que l'air comprimé est appliqué à l'élément de frappe, et qui guide de telle sorte que l'élément de frappe est entraîné dans la direction linéaire ; et un dispositif de rotation de cylindre pour tourner l'élément de cylindre à un angle prédéterminé sur la base de la direction linéaire. 본 발명은 그 구조가 매우 간단하고 저렴한 비용으로 제작이 가능하면서도 다양한 구질의 타구를 일정하게 반복적으로 발생시키는 것이 가능하며, 특히 종래에 사람의 능력이나 기계의 능력으로도 구현이 힘들었던 다양한 스핀의 타구를 일정하게 반복적으로 발생시킬 수 있도록 하는, 볼 감지센서의 성능 시험장치 및 이에 이용되는 볼 타격 장치를 제공하기 위한 것이다. 이를 위한 본 발명의 일 실시예에 따른 볼 타격 장치는, 공기압을 발생시키기 위한 압축 공기를 저장하는 에어탱크; 상기 에어탱크에 저장된 압축공기의 공기압에 의해 추진력을 얻어 직선 방향구동되어 볼을 타격하는 타격부재; 상기 압축공기가 상기 타격부재에 작용하도록 중공된 내부를 형성하며 상기 타격부재가 직선 방향으로 구동하도록 가이드하는 실린더부재; 및 상기 실린더부재를 상기 직선 방향을 중심으로 소정 각도 회전시키도록 하는 실린더 회전장치를 포함한다.
