<p>PURPOSE:To erect and hold a display device supported rotatably by a device main body in a simple constitution at a desired angle by energizing a lock part at all times via an energizing member so that the lock part is engaged at a engaging part. CONSTITUTION:An operator holds up the rear end of a display device 3 to erect the device 3. In this case, a lock member 15 is turned counterclockwise against the force of a compression spring 19 with the cam functions of teeth between a lock part 15b and an engaging part 17. As a result, the engagement is released between both parts 15b and 17 and therefore the device 3 can freely turn around an axis within a 0 deg.-90 deg. range. When the turn of the device 3 is stopped at a desired angle, the part 15 is engaged again at the part 17. Thus the device 3 is erected and held as it is. In such a way, the device 3 supported turnably by a device main body 1 can be easily erected and held at a desired angle.</p> |
