PURPOSE:To observe either a floated image, a retracted image, a plane image, a left image or right image in response to the request of a viewer by using a control signal separated from a superimposing means so as to drive a shutter means corresponding to the switching mode of a switching means. CONSTITUTION:The shutter means is driven corresonding to the switching mode of the switching means by using a control signal separated from the superimposing means. A mode changeover switch 18 is connected to the superimposing switch 13 to control switches SW1, SW2 of the superimposing switch 13. The alternative mode position 18a switches the switches SW1, SW2 of the superimposing switch 13 alternately, a full open mode 18b turns on both the switches SW1 and SW2, a left open mode 18c turns on the switch SW1 only and a right open mode 18d turns on the switch SW2 only. Thus, the transmission or interruption of the light in the shutter device is controlled optionally. |
