A semiconductor IC, a capacitor, a chip resistor, and the like are mounted on a multilayer substrate, and constitute a drive circuit for a solid-state imaging device including the circuit of the circuit board described above. Here, this drive circuit
If necessary, it may be incorporated inside the monitor. Returning to FIG. 5, the imaging unit 2 has a cylindrical case 4, a window 9 for exposing a lens 8 is provided on the surface, and a first connection is provided at the neck of the cylindrical case 4. The part 10 is provided integrally. As can be seen from the figure, the width of the first connecting portion 10 and the diameter of the imaging unit 2 are almost the same size. The main body 3 is formed slightly wider than the first connecting portion 10. As described above, the drive circuit board of the solid-state imaging device is built in the main body 3, and the main body 3
Is determined by the height of the element mounted on the substrate. Further, a portion where the main body and the imaging unit 2 are connected to each other, that is, a portion where the first connecting portion 10 abuts on the main body 3 is provided with a second connecting portion that presses and supports the first connecting portion 10 from both sides on both sides. 11 and 12 are provided. Referring to FIG. 6, the first connecting portion 10, the second connecting portion 11, 1
2 is provided with a shaft hole having a symbol G, into which shafts having, for example, threaded ends are inserted, and covers 13 and 14 in which nuts are formed as shown in FIG. 4 are attached. . Between the cover 13 and the second connecting portion 11, a spacer 16 having a notch having a depth slightly smaller than the diameter of a shaft of a hook portion 15 described later is arranged. Similarly, a spacer 17 is provided on the opposite side. Therefore, when the cover 13 is squeezed, the covers 13 and 14 come into contact with the hook portions 15 and the hook portions are locked. The imaging unit 2 is separate from the cover 13
A lock mechanism is provided at the connecting portion, and is locked at an arbitrary position. That is, the covers 13 and 14
Merely locks the hook portion 15, and the imaging unit 2 is locked at an arbitrary position regardless of whether the cover is squeezed or not. Further, as shown in FIG. 4, a cord 18 is attached to the rear end of the main body 3, and a video signal from the main body is input through the cord through a connector attached to the monitor, and the monitor is connected to the monitor. The image is projected. This video signal is output to another monitor connected to the monitor. A feature of the present invention is that the solid-state imaging device 1 can be mounted on a desk or the like as shown in FIG. 4, and further, as shown in FIGS. 1, 2 and 3, on the upper portion 31 of the liquid crystal display unit 30. It can be placed. Returning to FIG. 4, the imaging unit 2 is turned in the direction of the arrow (vertical direction) by the connecting portion, and the main body 3 can be placed on the desk at a fixed angle by the insertion state of the hook portion 15. The hook portion 15 has a U-shape, and a lower end of the insertion rod 21 and a connecting rod 23 connecting the lower end of the insertion rod 22 are integrally formed in a U-shape. The opposing position of the connecting rod 23 is open, and the connecting rod 23 is attached such that the open portion is inserted toward the main body 3. As described above, the spacer 16,
17 is provided with a notch so that the insertion rods 21 and 22 can be inserted between the cover 14 and the spacer.
In other words, by loosening the cover 14, the insertion rods 21, 22
And a mechanism that can adjust the angle between the desk and the main body. For example, if the stoppers 24 and 25 at the head of the insertion rod are inserted so shallow that the stoppers 24 and 25 come into contact with the cover 14, the angle is large.
If 25 is inserted deeply away from covers 13 and 14, the angle will be smaller. Since the imaging unit 2 can be turned up and down only by about 90 degrees mechanically, the variable range of the imaging unit (up and down about 90 degrees) can be changed by inserting the insertion rods 21 and 22 of the hook 15.
Has been further expanded. The second feature is that the angle between the hook portion 15 and the main body 3 is substantially 90 degrees.
As shown in FIG. 3 and FIG. 3, the hook portion 15 is hooked on the upper portion 31 of the thin panel case 30. That is, the lower surface of the main body 3 is in contact with the rear surface 32 of the panel case 30, the insertion rods 21 and 22 are bent downward in an L-shape at the corners S, and the connection rod 23 is provided with a stopper 33. The stopper 33 is a surface that forms a corner integrally with the display panel upper surface 31, that is, a surface that is parallel to the display surface D and protrudes from the display surface.
It is in contact with 4. That is, the stopper 33 is the case surface 3
4, so that the solid-state imaging device does not fall. As further described with reference to FIG. 1, a further feature of the present embodiment is that the back surface 32 and the surface 34 of the terminal main body are sandwiched between the main body 3 and the stopper 33 (or the second support portion M). When viewed from the side as shown in FIG.
Of the first support portion and a second support portion M extending downward from the right end of the first support portion are provided in an L-shape, and the first support portion and the second support portion M are provided in an L-shape. The back surface 32 and the surface 34 can be sandwiched between the support portions. In addition, since the insertion degree of the first support portion can be adjusted by the cover 13, the monitor terminal can be firmly held and the solid-state imaging device can be fixed. In addition, since a stopper made of rubber is attached to the second support portion, the solid-state imaging device can be firmly fixed to the terminal if the rubber is sandwiched so as to be flat. Further, in the present embodiment, it is formed in a U-shape. However, the connecting rod 23 may be removed and used in two L-shapes. In this case, when it is used for a tabletop, the starting point is three points, so that the stability is increased. The corner of the terminal case is about 90
Therefore, the body 3 and the first support portion 21 form 90 degrees. Therefore, if the corner is other than 90 degrees, the cover 1
Loosen 3 to move and adjust the first support so that it just fits the corner. The same can be said for the second embodiment described later. As described above, as shown in FIGS. 1 and 2, the solid-state imaging device is hooked on the thin panel case 30 in which the panel is incorporated by using the hook portion 15, and the terminal is held by the stopper 33. In order not to fall. Further, since the direction of the imaging unit 2 can be changed, the operator of the terminal can be placed at an appropriate position and projected. FIG. 4
It is also possible to arrange on a table as shown in FIG. Moreover, even when a display such as a CRT is used, it can be mounted on the upper portion of the display. Further, in the state shown in FIG. 5, it is also possible to hold the main body by hand and project a document or the like. Therefore, various methods can be used for capturing images, and a very convenient solid-state imaging device can be provided. Next, a second embodiment will be described. The imaging unit 40 of FIG. 9 is obtained by inverting the imaging unit 2 of FIG. Therefore, the specific structure is exactly the same as that of the previous embodiment, and the description is omitted. This solid-state imaging device can also be arranged on a table, and as shown in FIG.
Since the hook portion 43 can abut on the surface 42 protruding from the display unit and the stopper 44 abuts on the surface 44 between the display and the surface 42, the solid-state imaging device Can be arranged without shifting in the direction of the arrow. In both embodiments, the protrusion indicated by the symbol T is integrated with the shutter for closing the lens, and the protrusion T can be closed by hand.
FIGS. 3 and 9 show a state in which the shutter is closed. 7, the case 41 protrudes from the periphery of the screen of the monitor terminal employing the CRT. Since the protrusion has the surface 42 having a width of 2 to 3 cm, the terminal upper surface and the surface 44 can be sandwiched. That is, the first support portion 46 of the hook portion 43 extending from the main body 3 extends along the protruding surface 42 of the monitor terminal, and bends in an L-shape along a surface 44 facing the screen via the corner. Thus, the second support portion 47 extends. Therefore, loosen the cover 13,
By adjusting the insertion of the hook portion, the projecting portion can be held between the main body and the second support portion. In addition, since the stopper 45 is made of rubber having elasticity, the solid-state imaging device can be attached without falling from the terminal if the rubber is flattened and the cover is closed. As a further feature, the main body 3 is formed heavier than the imaging unit 2. FIG. 8 shows a state in which it is placed on a CRT monitor terminal and is not pinched. The imaging unit is
If it is heavier than the main body, the solid-state imaging device easily falls because it is not locked. The main body 3 incorporates a circuit board and elements to be mounted thereon. If the weight is still light, select the thickness and material of the case, or add a weight such as a ballast to increase the weight. Need to be kept. This point may be adopted in the first embodiment. Increased stability when placed on a table.

According to the present invention, first, if the holding means for sandwiching the thin portion of the video monitor is provided, the solid-state imaging device can be fixed without separately providing a mounting means on the monitor. Second, if a hook portion is used as the attachment means, the thin portion can be sandwiched between the main body and the hook portion, and the hook portion can be used as a leg to be placed on a table. Third, since the back and front of the liquid crystal panel have no thickness, they can be sandwiched satisfactorily, and the portion protruding from the screen of the CRT can be sandwiched satisfactorily because of the small thickness. Therefore, the solid-state imaging device can be firmly attached to these monitors without having a separate attachment mechanism. Fourth, by making the main body heavy, the stability of the solid-state imaging device can be increased, so that the solid-state imaging device does not easily fall without being held by the holding means, and can be stably held between monitors.
