 note = {It is vey difficult to change simultaneously the pitching speeds and the course in the usual used pitching machines of the arm type and the two rollers type. In this study, the pitching machines which is able to pitch exactly a base ball into various courses and speeds using the three rollers controlled independently the number of rotations, is developed. In the pitching machine, the layered neural network system in which the learning data use each course and speeds as input data and number of rotation of each roller as output data is used. This machine is one of the intelligent sport machine. In this paper, the system and its machanism are described., 金沢大学工学部},
