PURPOSE:To prevent a device from turning during operation by fixing the longitudinal shaft of a turning supporting arm to a prescribed hooking position of a positioning means and setting an arm part to a prescribed angular position. CONSTITUTION:A spring pin 40 of a turning supporting arm 27 is fitted to and engaged with prescribed one selected from plural recessed parts 26 provided on a holder part 8 to set an arm part 28 to a prescribed angular position to a printer A, thereby setting a display device to a required position. In this state, an arm shaft 32 is not turned during the operation of the printer A as conventional because the pin 40 is fitted to and engaged with the recessed part 26 as it is. It is not turned even if the display device is inclined and operated through a tilt swivel mechanism 59 or a third person touches this device. |
