PUCK FOR AMUSEMENT DEVICE OR EXERCISE DEVICE USING ACUPRESSURE PLATE CAPABLE OF VARYING FRICTION LEVELS OF PLAY SURFACE ACCORDING TO USER'S SKILL AND EXPERIENCE

摘要

PURPOSE: A puck for amusement device or exercise device using an acupressure plate is provided which is capable of varying friction levels of a play surface according to user's skill and playing experience to increase user's satisfaction and excitement. CONSTITUTION: The puck comprises: an upper surface contacting with the ground in a widened area to increase a friction coefficient; a lower surface contacting with the ground in a narrowed area to decrease a friction coefficient; and a light emitting unit configured to flicker when an external impact is applied to the puck and having a power supply(30), a mode switch(32), an impact sensor(33), a pulse generator(34), a flickering pulse signal generator(36), a melody circuit(37), and first and second light emitting diodes(38,39).
