<p>PURPOSE:To steplessly fix a display unit at an optional angle. CONSTITUTION:When the display unit 1 is rotated by a hand in the direction of the arrow I e.g. a blade 4 is also rotated around a spindle 3 similarly to the body of the unit 1. Thereby the end part 51 of a friction arm 5 is moved in the arrow K direction only by a distance corresponding to the rotational angle of the unit 1 while sliding on the surface of a slide groove 8 and a friction spring 7. When the hand is removed, the unit 1 tries to rotate in the arrow J direction by gravity, but frictional force is applied among the arm 5, the groove 8 and the spring 7 and force for rotating the unit 1 in the arrow I direction is applied to the blade 4, so that the unit 1 is not rotated and the angle held at the time of removing the hand can be held and fixed.</p> |
