The button battery 45 is formed in a disk shape in which the surface is a metal body, and has the heaviest quality as compared with all other elements.

The wiring board 50 is generally referred to as a Rigid flexible printed board, as shown in FIG. The plurality of flexible portions 51 are formed with a plurality of rigid portions 53 having rigidity. The rigid portion 53 of the wiring substrate 50 is formed thicker than the flexible portion 51 as shown in FIG.

As shown in FIG. 3, the flexible portion 51 is formed of a first flexible portion 51a having a long rectangular shape, a second flexible portion 51b formed into a short rectangular shape, and a shorter length. The three rigid portions 53c of the rectangular shape are configured in three parts, and the plurality of rigid portions 53 are the first rigid portions 53a that are formed into a substantially circular shape in a plan view, and the second rigid portions that are substantially circular in a plan view. The portion 53b and the third rigid portion 53c formed in a substantially square shape in a plan view are configured.

The acceleration sensor 31a can detect the stationary state of the baseball ball. Further, the angular velocity sensor 31b can detect the movement of the ball. Since the acceleration sensor 31a and the angular velocity sensor 31b are not affected by the metal body, even if the metal body, that is, the button battery 45 is in the vicinity, there is no problem and measurement can be performed. Further, since the acceleration sensor 31a and the angular velocity sensor 31b are mounted on the center of the substrate surface 41a of one of the circuit boards 40, they are less likely to be affected by the centrifugal force, and the measurement can be performed accurately.

The start of the pitching motion of the pitcher described above can be detected by the angular velocity sensor 31b. Generally, the angular velocity sensor 31b can output at least several detection values even if the ball moves only slightly, and the angular velocity sensor 31b detects before the pitcher enters the pitching motion, that is, in a state where the fixed posture (SET POSITION) is stationary. The value becomes equal to or less than the specified value. Therefore, when the detected value of the angular velocity sensor 31b is equal to or lower than the predetermined value, it can be determined that the pitching operation of the pitcher is started. Therefore, the position of the ball at this time becomes the reference position of the measurement. Further, the acceleration sensor 31a can be used in combination in the determination of the reference position.

Thereafter, after the pitcher performs the pitching operation, information on the rotation direction of the ball, the rotation speed, and the position of the ball with respect to the reference position is obtained, and the data is recorded on the memory element 37 mounted on the circuit board 40.
