(30) In an embodiment of the present invention, the control unit 120 causes the vibration unit 150 to output the vibration when the position and direction of the putter head 20 coincide with the reference position and direction.

(31) FIGS. 3 and 4 are diagrams illustrating a display unit of the digital putting diagnosis device according to the embodiment of the present invention.

(32) Referring to FIGS. 3 and 4, in the embodiment of the present invention, on the display unit 130, a putter rotation angle 131 at an address position as a position where the putter head 20 touches the ground during the putting is displayed, the path center line 132 is displayed, the swing path 133 is displayed, and the number of times of hitting 134 is displayed.

(33) In one embodiment of the present invention, the display unit 130 may be configured with a TFT LCD, an OLED, or the like.

(34) In one embodiment of the present invention, the control unit 120 turns on the power of the display unit 130 when the putter head 20 is located within a predetermined angle or less, and the control unit turns off the power of the display unit 130 when a predetermined time elapses after the putter head deviates from the predetermined angle. For example, the control unit 120 turns on the power of the display unit 130 when the putter head 20 is located in the range of +5 degrees to 20 degrees with respect to the X axis and within 20 degrees with respect to the Y axis, and the control unit 120 turns off the power of the display unit 130 after 5 seconds has elapsed from the time when the putter head deviates from the range.

(35) The control unit 120 may perform a real-time zero point adjusting function of setting the position and direction of the putter head 20 at that time as reference position and direction if the putter head 20 does not move in the Z axis direction for a predetermined time. And then, the control unit displays the reference position and direction on the display unit 130 and and displays a changed angle on the display unit 130 in real time when h the putter head 20 rotates about the Z axis if the reference position and direction are set.

(36) In the embodiment illustrated FIGS. 3 and 4, the first light emitting unit a, the second light emitting unit b, and the third light emitting unit c are included at the putter rotation angle 131. The first light emitting unit a, emits red light, the second light emitting unit b emits yellow light, and the third light emitting unit c emits green light.

(37) In the embodiment illustrated in FIGS. 3 and 4, when the zero point adjusting function is performed, the control unit 120 sets the position and angle of the putter head 20 at that time to 0 degrees, and the third light emitting unit c emits light at the putter rotation angle 131 of the display unit 130 to be displayed in green. At this time, if the angle of the putter head 20 is within 2 degrees or less, the control unit 120 can allow the third light emitting unit c to emit light to be displayed in green.

(38) When the putter head 20 rotates by a predetermined angle or more about the Z axis, the control unit 120 displays the position and angle of the putter head 20 at that time in different colors. In the embodiment illustrated in FIGS. 3 and 4, the control unit 120 causes the second light emitting unit b to emit light at the putter rotation angle 131 when the putter head 20 rotates by 4 degrees about the Z axis to be displayed in yellow. Then, when the putter head 20 rotates by 8 degrees about the Z axis, the first light emitting unit a emits light at the putter rotation angle 131 to be displayed in red.

(39) As described above, in the present invention, the portion indicating the putter rotation angle 131 of the display unit 130 is set such that the green line of the third light emitting unit c is located at the center, the current position of the putter head 20 can be displayed in the form of a bar according to the rotation angle of the putter head 20, the second light emitting unit b can be displayed by a yellow line, and the first light emitting unit a can be displayed by a red line.

(40) Therefore, the user can easily check the position of the current putter head 20 and adjust the putter head 20 to be located correctly in the address posture.

(41) At the center of the display unit 130, two path center lines 132 are displayed.

(42) In the present invention, the control unit 120 detects the moving path of the putter head 20 in real time and displays the moving path in the path center line 132.

(43) That is, the control unit 120 sets 0 degree as a reference with respect to the X-axis and Y-axis, detects the movement of the putter head 20, and displays the swing path 133 in real time in the path center line 132. At this time, when the putter head 20 moves backward in the X axis direction, the swing path is displayed in second color 420, and when the putter head 20 moves forward, the swing path is displayed in first color 410.

(44) For example, the first color 410 may be blue, and the second color may be red.

(45) At this time, the angle range in which the swing path of the putter head 20 can be displayed can be set. For example, the angle range may be set to a range of 0 to 17 degrees with respect to the X axis and a range of 5 degrees with respect to the Y axis.

(46) The control unit 120 detects whether the golf ball has been hit by detecting the changed impulse and the time when the impact is generated through the putter head 20. When it is determined that the golf ball has been hit, the control unit displays the cumulative number of times of hitting on the display unit 130 in real time.

(47) In the embodiment of the present invention, the control unit 120 turns off the power of the digital putting diagnosis device 100 when the putter head 20 deviates from the predetermined angle range for a predetermined time or more.

(48) For example, the control unit 120 turns off the power when the putter head 20 deviates from the range of +5 degrees to 20 degrees with respect to the X axis and the range of 20 degrees with respect to the Y axis for 3 minutes or more.

(49) In one embodiment of the present invention, the control unit 120 can display a hitting error on the entire display unit 130 in a red blinking manner in a case where the rotation of the putter head 20 is 2 degrees or more with respect to the Z axis at the hitting time.

(50) In an embodiment of the present invention, the control unit 120 receives a signal from the illuminance sensor 160, which detects indoor light or outdoor light, and distinguishes the indoor and the outdoor from each other to automatically adjust the brightness of the screen of the display unit 130.

(51) Accordingly, even in a case where the user uses the putting diagnosis device outdoors, the user can easily check the information displayed on the display unit 130 visually.

(52) In the present invention, in order to reduce power consumption, the power of the digital putting diagnosis device 100 can be turned off when the display unit 130 is not turned on again for a predetermined time or more after being turned off.

(53) For example, the power of the digital putting diagnosis device 100 can be turned off when the display unit 130 is not turned on again for three minutes or more after being turned off.

(54) As illustrated in FIGS. 3 and 4, when the right side of the display unit 130 is set to the direction of the head face 3, a path center line 132 in which two white lines are formed in the horizontal direction is displayed, the swing path 133 is displayed in the path center line 132, the putter rotation angle 131 is displayed on a portion of the left side of the path center line 132, and the number of times of hitting 134 is displayed in the upper right side portion.

(55) However, this configuration is only an embodiment, and a specific display method in the display unit 130 can be variously implemented.

(56) While the invention has been described in terms of several preferred embodiments, these embodiments are illustrative and not restrictive.

(57) It will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit of the invention and the scope of the appended claims.
