The page shown in FIG. 1 above is a page corresponding to the captain system. That is, the first page 20 of this captain system has a vertically long rectangular shape, and an ear 20a is formed in the upper right corner so that "Captain" can be displayed there. A first light-receiving element R8 is disposed on the back surface side.

As shown in FIG. 1b), this light-receiving element R0 is attached to the bottom side of a groove 10a formed in the vertical direction in the center of the base plate 10. As shown in Fig. 3, a condensing lens L is attached. Then, the ear portion 20a of the first page 20
does not cover this light-receiving element R1, for example, the light from a fluorescent lamp is received by this light-receiving element R1, so it is turned on, and this light-receiving element R1
This makes it possible to determine whether the image is not covered by the

Furthermore, the light receiving element R8 is attached to the uppermost end side of the groove 10a (as shown in FIG. 1(a)), and below the light receiving element R6, four light receiving elements R2 are placed with a certain pinch in between. , RL Ra, and Rs are arranged in sequence.

When the first page 20 is opened, the tab 20a covers the light receiving element R1.
is turned off, making it possible to determine that it is "covered by the first page."

Similarly, when the third page 22 is opened, three light receiving elements R1, R2, R3 are displayed as shown in FIG.
is covered by the edge portion 22a of the third page 22, etc., and is configured to block light (turn off).

The left end of the first page 20 is configured to be foldable by appropriate means, and this foldable portion is fixed to the left end of the base plate 10 (see FIG. 1(b)). .

Figure 1 shows the operation of the Captain System, and the page on the right is the ``Table of Contents'' screen.

Eight inputs such as "screen reservation" and "start/stop scrolling" can be made.

That is, in the area of the above-mentioned "Table of Contents Screen", a first area 18 is formed in the shape of a horizontally long oval, with the words "Table of Contents Screen" on the top and the words "Call Table of Contents Screen" on the bottom. is entered. A round hole 18a large enough to fit a human finger is formed on the right end side of the first area 18, and the push button 18b is mounted so that the tip thereof is exposed from this round hole 18a. . By pressing the button 18b with a human finger through the circular hole 18a, input to the above-mentioned "table of contents screen" can be performed.

Furthermore, below the first area 18 is a second area 19.
