<p>PURPOSE:To hold an angle of opening of a heavy display device by linking a one-way clutch and a running face ratchet, which are interlocked with the rotation of the display device, to a revolving shaft of the display device. CONSTITUTION:When a display device is rotated in such direction that a coiled spring 13 is clamped to a revolving shaft 11 and a gear 12, the coiled spring 13 displays the function of the one-way clutch to transmit the power to a gear 14. At this time, gears 12 and 14 and a compression spring 16 function as the running face ratchet mechanism to hold the angle of opening of the display device 10. When the display device 10 is rotated in such direction that the coiled spring 13 is loosened, the rotating force is not transmitted to the gear 12 and only the display device 10 is rotated. Thus, a stable opening angle holding force is displayed for a light display device as well as a heavy display device.</p> |
