PURPOSE: A collimator for golf club, which quantitatively measures the inclination of golf green and displays it, is provided to precisely measure and display the inclination degree of the golf green which the golf club is located in so as to help a user, who practices the putting, to improve the reading ability of the green state. CONSTITUTION: The collimator for golf club includes: an angle detecting unit, detecting the inclined angle using the gravity difference between two points of the golf club; a controller, generating a control signal for displaying the inclination degree of the golf club according to the inclined angle detected by the angle detecting unit; and a display, displaying the inclination degree of the golf club according to the control signal of the controller. The angle detecting unit comprises: a gravity detecting sensor(10), detecting the gravity on any two points of the golf club and outputting the detecting signals of each voltage level corresponding to the detected gravities; a comparator(20), outputting a comparison signal; and an Analog-to-Digital converter(30,50). |
