Abstract: A golf ball 2 includes a main body 4 and a paint layer 6 positioned outside the main body 4. The main body 4 includes a spherical core 8, a mid layer 10 positioned outside the core 8, and a cover 12 positioned outside the mid layer 10. The paint layer 6 includes an inner layer 14 and an outer layer 16 positioned outside the inner layer 14. When an indentation depth (nm) is measured on a cross-section along a plane passing through a central point of the golf ball 2 when a force of 30 mgf is applied to the cross-section in a direction perpendicular to the cross-section, an indentation depth Di on a cross-section of the inner layer 14 is lower than an indentation depth Do on a cross-section of the outer layer 16.

Abstract: A golf ball 2 includes a core 4, a mid layer 6, a cover 8, and dimples 10. A Shore C hardness Hmc of the mid layer 6 is greater than a Shore C hardness Hs at a surface of the core 4. A Shore D hardness He of the cover 8 is less than a Shore D hardness Hm of the mid layer 6. Peak values and orders of maximum peaks of data constellations of the golf ball 2 are calculated. A minimum value of the peak values is not less than 95 mm. A minimum value of the orders is not less than 27, and a maximum value of the orders is not greater than 37. An average of the orders is not less than 30 and not greater than 34.

Abstract: A golf ball 2 includes a main body 4 and a paint layer 6 positioned outside the main body 4. The main body 4 includes a spherical core 8, a mid layer 10 positioned outside the core 8, and a cover 12 positioned outside the mid layer 10. An indentation depth, measured when the paint layer 6 in a cross-section along a plane passing through a central point of the golf ball 2 is pressed by a force of 30 mgf in a direction perpendicular to the cross-section, is not less than 300 nm and not greater than 3000 nm. The paint layer 6 preferably has a thickness of not less than 5 μm and not greater than 50 μm.

Abstract: A measuring apparatus 10 for a golf club 34 includes: a club camera 20 capable of photographing the golf club; a control part 30 capable of controlling a timing at which the golf club is photographed; and three sensors capable of detecting passage of the golf club 34. The three sensors are defined as a first sensor S1, a second sensor S2, and a third sensor S3 in this order from a point close to a position of a golf ball. When a club speed calculated based on the passage of the golf club detected by the second sensor S2 and the third sensor S3 is equal to or greater than a predetermined threshold value, the control part generates a trigger signal for starting to photograph the golf club. The measuring apparatus 10 can effectively suppress erroneous generation of the trigger signal.

Abstract translation: 用于高尔夫球杆34的测量装置10包括：能够拍摄高尔夫球杆的球杆照相机20; 能够控制拍摄高尔夫球杆的时间的控制部30; 以及能够检测高尔夫球杆34的通过的三个传感器。三个传感器从接近高尔夫球的位置的顺序被定义为第一传感器S1，第二传感器S2和第三传感器S3。 当基于由第二传感器S2和第三传感器S3检测到的高尔夫球杆通过而计算的球杆速度等于或大于预定阈值时，控制部分产生用于开始拍摄高尔夫球杆的触发信号。 测量装置10可以有效地抑制触发信号的错误产生。
