The second block 2 includes therein a lighting means 16 whose lighting is controlled by receiving power supply from the power supply circuit 7 via a switch 15.
It is used as a backlight for the liquid crystal display section in the block 3, and the third block 3 is used as the illumination means 1.
It can also be removed from the front of 6 and used as general lighting. Note that the knob 15a in block 1 is for operating the switch 15 mentioned above. The third block 3 includes a liquid crystal display section 17 having a transmissive liquid crystal display panel, and this liquid crystal display section 17 transmits the image signal from the image signal generation circuit 8 to the first switch 1.
1 and displays moving images using the illumination means 16 as a backlight. Further, the respective outputs of the on signal generating circuit 18 and the off signal generating circuit 19, which are respectively controlled by the control signal from the control signal generating means 9, are connected to the second to fourth switches 12,
13, 14 and the first switch 11, and the color display selected by the second to fourth switches is displayed on the liquid crystal display section 17.

The first connecting means 4 connects the first block 1 and the second block 2, and is constituted by, for example, a flexible arm having one end fixed to the first block 1 and the other end fixed to the second block 2. be done. By utilizing the movability of this flexible arm, the setting position of the second block 2 can be arbitrarily selected. In this way, the first connecting means 4
Any configuration may be used as long as it can ensure the arbitrariness of the setting position of the second block 2. In addition to the above embodiments, for example, a plurality of arms and a universal joint provided at the connection part of each arm may be used. Combination configurations are available.

The second connecting means 5 connects the second block 2 and the third block 3, and can selectively set the liquid crystal display 17 to two positions, open and closed, with respect to the illumination means 16 in the second block. . For example, the second connecting means 5 connects the second block 2 to the third block 3.
It consists of a hinge on which the block is rotatably attached, and means (not shown) on the opposite side of the hinge for making both blocks 2 and 3 detachable. The third block 3 is configured to take a closed position as shown in FIG. 2 and an open position as shown in FIG. 3 relative to the second block 2. Apart from this embodiment, the second connecting means 5 may be configured to be detachable so that the third block 3 can be separated from the second block 2 (see the above-mentioned Utility Model Application No. 157954/1989).
In this case, by providing a battery power supply and predetermined circuits such as an image signal generation circuit in the third block 3,
