The lock mechanism 43 having the same structure is provided on the two legs 19 and 21.

(Operation) The operation of this embodiment will be described below. First, the two legs 19 and 21 are placed on a desk or the like in a state of being extended in a substantially L shape. Two legs 19, 21
The document 51, which is the subject, is placed between the two. And platform 5
Is supported on the upper end of the column 11. This support is for the column 1
The shaft 59 is rotated by rotating the attachment / detachment ring 55 of the support portion 53 (FIG. 3) provided at the upper end of the shaft 1.
The male screw 63 formed at the tip of the
The support portion 53 and the supported portion 67 are firmly connected by being screwed into the female screw 63 formed on the. And each leg 19, 2
The rotary leg 37 is taken out from the first storage slit portion 39 and rotated. During this removal, the release button 111 is pressed so that the boss 115 can be removed from the boss hole 117.

When connecting the supporting portion 53 and the supported portion 67, the supporting portion 67, which is a connector, and the signal pins 71 and 73 of the supporting portion 53 are also connected. Then, the image information from the document 51 is taken in by the camera unit 3 and converted into an electric signal, and the image is displayed on the monitor 91 by this electric signal. The electric signal of this image information is also fetched by the computer 95. At this time, the operation control of the platform portion 5 is performed by a switch provided in the circuit box 87 or an operation from a computer.

As described above, when the platform 5 is supported on the upper end of the column 11, it is necessary to manually operate the camera unit 3. In such a case, when an external force is accidentally applied in the f direction, the device is less likely to fall than in the conventional case.

That is, if the device 1 falls over, the device 1 should rotate about the line 123 connecting the tips of the two rotation legs 37. If the rotary leg 37 is not provided as in the conventional case, the device 1 should rotate around the line 35 connecting the tips of the two leg portions 19 and 21. The line 123 connecting the tips of the rotating legs 37 is farther from the base 17 than the line 35 connecting the tips of the legs 19 and 21. In other words, the length R2 of the perpendicular line 125 drawn from the base 17 to the line 123 connecting the tips of the rotating legs is equal to the vertical line 1 drawn from the base 17 to the line 35 connecting the tips of the legs.
It is longer than the length R1 of 27. Therefore, the stability of the device 1 is improved. In particular, if the length R2 of the perpendicular line 125 is longer than the length of the column portion 11, the device 1 is in a safe state against falling. That is, even if the device 1 is tilted, the device 1 is restored by its own weight and returns to the original state.

Next, the operation of folding the legs 19, 21 and the like after using the image input device 1 will be described.

First, the operator of the apparatus operates the circuit block 87 or the computer 95 to operate the camera platform 5 so that the camera section 3 is in a substantially horizontal position. Then, the attachment / detachment ring 55 at the upper end of the column 11 is rotated to remove the camera platform 3 and the platform 5.

In such a detaching work, the rotation leg 37 serves to stabilize the device 1 and the workability.

After that, the turning leg 37 is held in the hand, and the release button 111 is pushed and rotated to be stored in the storage slit portion 39. Then, the two leg portions 19 and 21 are rotated in the horizontal plane in the directions A and B (FIG. 1) to align them in parallel with each other. After that, the two leg portions 19 and 21 are rotated in the C direction in the vertical plane (FIG. 3), housed toward the notch 33, and placed in parallel with the column portion 11. This makes leg 1
The folding of 9 and 21 is completed. In the rotation in the vertical plane, the leg portion 19 supported by the rotary plate 23 provided inside of the two rotary plates 23 and 25 is rotated first, and the other leg portion 21 is rotated. Turn later.

FIG. 5 shows a state in which the device 1 folded in this way is housed in the case 129. This case 12
In addition to the two legs 19, 21, the column 11, and the base 17, the camera unit 3 and the platform 5 that have been removed and the cable 8
3 and the circuit block 87 are efficiently arranged. When stored, the vertical m is about 60 cm, the horizontal n is about 20 cm, and the thickness is about 20 cm, which is compact and convenient to carry.

As described above, according to this embodiment, the turning leg 37 provided at the tip of each of the two leg portions 19 and 21 serves to enhance the stability of the entire apparatus 1 and prevent it from tipping over. It can be prevented. That is, the line 123 connecting the tips of the two rotary legs 37 is located farther than the line 35 connecting the tips of the two leg portions 19 and 21. When the device 1 falls, it should rotate around the line 123, so
Since the position 23 is farther from the base 17, the stability of the device 1 against falling is increased. Particularly, when the length R2 of the perpendicular line 125 drawn from the base 17 to the line 123 connecting the tips of the two turning legs 37 is longer than the length of the support column 11, the device 1 is safe against falling. In this state, even if the device 1 is tilted, it returns to its original state due to its own weight, and has resilience.

In the above embodiment, the release button 11 of the lock mechanism 43 is pushed to release the lock, but in the second embodiment, a release button is provided as shown in FIG. Alternatively, the click mechanism 143 can be adopted as the lock mechanism. That is, the pin 147 having the spherical surface 145 at the tip is provided so as to be retractable from the surface of the rotary leg 37 while being biased by the spring 149. The pin hole 151 into which the tip of this pin 147 is fitted is
It is formed on the ceiling of the storage slit portion 39.

With the above structure, if the force for rotating the rotating leg 37 is less than a certain value, the pin 147 remains fitted in the pin hole 151 and is not rotated.
However, if the force to rotate the pin 147 exceeds a certain level, the spherical tip of the pin 147 is pin hole 151.
Is pushed by the edge of the spring 149 and sinks against the biasing force of the spring 149. Rotation is easily performed in this depressed state.

In this way, the rotary leg 37 has the leg portion 19,
It is possible to maintain the locked state with respect to 21 at a predetermined rotation angle, and unlock the lock by applying a turning force of a certain value or more.

Further, in the above embodiment, the boss hole 11
7 or the pin hole 151 is provided at two places, and the rotary leg 3
7 was locked at two rotation angle positions,
In other embodiments, the present invention is not limited to this, and it is also possible to provide three or more boss holes or pin holes and lock the turning leg at three or more turning angles.

Further, in the above embodiment, the fall prevention means is the turning leg 37 provided at the tips of the two leg portions 19 and 21, but in the third embodiment, the two leg portions are provided. 1
It may also be a subject mounting plate that fits into 9, 21. That is, as shown in FIGS. 10 and 11, the two leg portions 19,
On the inner side surface of 18, a groove 131 is formed in the longitudinal direction. The edge of the square subject placement plate 133 is fitted into the groove 131. On the lower surface of the tip of the subject mounting plate 133 is a seat 13 made of rubber or plastic.
5 is provided, and the subject placing plate 13 is attached to the legs 19 and 21.
3 is kept horizontal. In addition, the seat 135 can prevent slipping on a desk or the like and can absorb a vibration. In addition, in the portion of the subject mounting plate 133 that contacts the base portion 17,
The arc-shaped notch 137 is provided to prevent interference with the base portion 17. The subject placing plate 133 can be folded in two by a folding line 139 at the center by a folding means (not shown).
As a result, the subject placing plate 133 can be folded into about half the area and stored in a case (not shown).

With the above structure, the tip corner portion 141 of the subject mounting plate 133 supports the position farther from the base portion 17 than the line connecting the tips of the two leg portions 19 and 21. Similarly, it is possible to enhance the stability of the device against a fall.
