<p><P>PROBLEM TO BE SOLVED: To provide a positioning mechanism for rotary display capable of precisely positioning a rotary display within a hollow frame with enhanced convenience in using in addition to convenience in manufacturing or assembling by applying the simple lever principle and designing a connecting rod structure. <P>SOLUTION: The rotary display is pivotally provided within the hollow frame to be rotatable to the left and right sides relative to the hollow frame, and positioning holes are provided in the upper rail and lower rail of the hollow frame. A positioning mechanism is incorporated with the rotary display. The positioning mechanism comprises an upper connecting rod and a lower connecting rod connected to a lever device. The lever device is pressed and rotated by manual operation of an operation means to drive the upper and lower connecting rods for generating an axial motion, and the upper and lower connecting rods form the positioned or separated state with the respectively corresponding positioning holes of the hollow frame. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
