The present invention has been made in view of these points, and an object of the present invention is to provide an attachment device capable of improving the attachment stability when attaching an image communication camera or the like to a notebook computer or the like. .
[0005]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided an apparatus main body to which a body to be attached is attached, a support surface provided on the bottom surface of the apparatus main body and supported by a mounting counterpart, and formed at a fixed angle with respect to the support surface. An engaging portion that engages with one side surface of the mating member, a pressing portion that is arranged in parallel with the engaging portion and is moved in this parallel posture and engages with the other side surface of the mounting partner, and the pressing portion. An urging means for urging the locking portion side, and the pressing portion is parallel to the locking portion at the tips of two arms pivotally supported in a plane parallel to the support surface portion. As the biasing member provided, a plurality of torsion coil springs are provided as the biasing means for the arm, and the biasing means is provided on the two arms so as to bias the arm in the leg-opening direction. The torsion coil spring and the arm provided between the two arms are attached in the direction of the legs. And the number of turns of each coil portion of the first torsion coil spring and the second torsion coil spring is the second with the first torsion coil spring overlaid on the arm. It is the attachment apparatus set so that height might be substantially equal to the torsion coil spring.

Further, the pressing portion opens and closes in parallel with the locking portion, and the attachment partner is stably held between the locking portion and the pressing portion. By rotating the two arms, the pressing portions are opened and closed while being parallel to the locking portions, respectively, and respond to changes in the thickness of the mounting counterpart. Further, when the attachment partner is thinned, the leg of the arm is enlarged, so that the interval between the two pressing parts is widened, and the insufficient support of the support surface part by the attachment partner can be compensated. By using a plurality of torsion coil springs and reducing the number of turns of each torsion coil spring while obtaining a predetermined urging force comprehensively, the height of the spring can be kept low, and the size of the mounting device can be suppressed. The second torsion coil spring has more coil turns than the first torsion coil spring, and the two springs have the same height so that the two torsion coil springs can be efficiently stored in a narrow storage space. To do.

As described above, by using the plurality of torsion coil springs 51 and 52, the number of turns of the coil portions 53 and 57 can be reduced while obtaining a predetermined biasing force. By suppressing the height of the portions 53 and 57, the mounting device can be prevented from being enlarged.
[0027]
The number of turns of the coil portions 53 and 57 of the first torsion coil spring 51 and the second torsion coil spring 52 is determined by overlapping the base end bearing portions 42 of the two arms 24 on the rotating shaft support portion 41 and further fitting them. In a state where the coil portions 53 of the first coil spring 51 are overlapped and fitted, their total height is set to be equal to the height of the coil portion 57 of the second torsion coil spring 52. That is, the number of turns of the second coil spring 52 is greater than the number of turns of the first coil spring 51. With this structure, the torsion coil springs 51 and 52 can be stored in a narrow (thin) arm rotation space of the apparatus main body 11 in a space-efficient manner.
[0028]
Further, as shown in FIG. 3A, four screw mounting base portions 61 are integrally formed on the back surface of the apparatus main body 11 at symmetrical positions, and the screw mounting base portion 61 and the arm 24 are connected to each other. A screw hole 62 is provided in each of the rotation shaft support portions 41.

As shown in FIG. 2B, the bottom plate 22 is fixed by screws 66 inserted from the screw insertion holes 63 of the bottom plate 22 and screwed into the screw holes 62 on the apparatus main body 11 side. The fixed bottom plate 22 guides the movement of the pin 48 of the arm 24 by the arcuate groove 65 located on the inner side, and smoothly rotates the arm 24 and prevents the torsion coil springs 51 and 52 from coming off. Have
[0031]
As shown in FIGS. 4 to 6, the CCD camera 12 is provided with an imaging window 71 and a focus adjustment dial 72 at the center of the front surface of the camera body 32. The electric cord 73 is drawn out.
[0032]
Next, the operation of this embodiment will be described.
[0033]
When the CCD camera 12 is attached to the open display 13 of the notebook personal computer with this attachment device, two torsion coils centering on the rotating shaft support 41 are used as shown in FIG. By rotating the two leg portions 25 in the B direction against the restoring force of the springs 51 and 52 in the A direction, the two leg portions 25 are once opened with respect to the front plate 23, as shown in FIG. Of the torsion coil springs 51 and 52 acting on the two legs 25 by fitting the upper side of the open display 13 relatively between the back surface of the front plate 23 and the two legs 25. When the repulsive biasing force (restoring force) in the A direction is released, the CCD camera 12 can be attached to the upper side of the open display 13 so that the display 13 is sandwiched between the front plate 23 and the two legs 25. .
[0034]
At this time, not only the front plate 23 is engaged with the front side of the open display 13 of the notebook computer, but also the two legs 25 are engaged with the rear side of the display 13, and at the same time, the bottom plate 22 is attached to the upper side of the display 13. By engaging with the surface portion 21, the mounting stability of the CCD camera 12 is increased. That is, in addition to sandwiching the display 13 between the front plate 23 and the leg portion 25, the bottom plate 22 is supported by the upper side surface portion of the display 13, so that it is sandwiched as in the conventional clip 2 (FIG. 7). The mounting stability can be improved as compared with the clamping of.
[0035]
In addition, the conventional clip 2 (FIG. 7) can clamp the mounting partner only at the tip portion, so that the clamping is unstable. However, the mounting device has two arms 24 in a plane parallel to the bottom plate 22 respectively. By rotating, the two leg portions 25 can always be moved in parallel with the front plate 23. Therefore, even if the distance between the front plate 23 and the leg portion 25 changes, the display 13 is moved to the front plate 23. Can be sandwiched between the front surface of the leg and the entire length of the leg portion 25, and a stable clamping state can be obtained.
[0036]
For this reason, within the range of the notch 36 where the two legs 25 can freely rotate, it can respond to changes in the thickness of the notebook PC display 13 and can be mounted on any notebook PC display 13 without any problems. It is.
[0037]
At that time, the sandwiching can be stabilized by two leg portions 25 provided in the width direction of the front plate 23. In addition, when the display 13 is attached to a thin display 13, the support area on the bottom plate 22 is reduced. However, if the display 13 is thin, the leg opening angle of the arm 24 is increased and the distance between the two leg portions 25 is increased. Insufficient support due to the bottom plate 22 can be compensated.
[0038]
In addition, since the repulsive urging forces of the two torsion coil springs 51 and 52 act strongly on the two leg portions 25, the mounting stability can be improved by these repulsive urging forces. At that time, as shown in FIG. 3A, the first torsion coil spring 51 has both ends 54 and 55 inserted into the ribs 46 and 47 of each arm 24 so that the pin 48 is inserted inside the rib 47. The second torsion coil spring 52 is biased toward the front plate 23, and the arms 24 are biased toward the front plate 23 from the outside of the rib 47, so that the torsion coil springs do not interfere with each other.
[0039]
Further, as shown in FIG. 1, the attachment device is used in a state in which the display 13 of the notebook personal computer to be attached is inclined to the back side, and a tilt shaft 34 provided on the front side of the device body 11 is used. The camera body 32 of the CCD camera 12 is rotated to the front side so that the center of gravity of the camera body 32 is positioned as far as possible in front, and a leg 25 that holds the display 13 from the back side is formed longer than the front plate 23. Thus, by closely contacting the back surface of the display 13, load support on the back side of the display 13 is ensured, and the possibility that the mounting device will fall off to the back side of the display 13 is prevented.
[0040]
As described above, the mounting position of the CCD camera 12 is set to the upper side portion of the display 13 in the open state, and the bottom plate 22 is brought into contact with the upper side surface portion 21 of the display 13 to improve the mounting stability of the camera 12. In addition, the anti-slip action of the rubber cylinder 28 fitted to the two leg portions 25 and the rubber plates 27 and 29 attached to the back surface and the bottom plate 22 of the front plate 23 ensures the above mounting stability. For example, the CCD camera 12 is not detached from the display 13 of the notebook personal computer due to vibration.
[0041]
Furthermore, the position of the CCD camera 12 after being attached to the display 13 can be easily adjusted by the front-rear tilt mechanism. By adjusting the angle of the camera body 32 about the tilt shaft 34 in the front-rear direction, the position can be adjusted in an appropriate direction. The orientation of the imaging window 71 of the CCD camera 12 can be set, and a correct and beautiful image can be captured from the CCD camera 12.
[0042]
Note that the present invention is not limited to the attachment device for attaching the CCD camera 12 to the display 13 of the notebook personal computer, and can be used as an attachment device for attaching other devices to other devices, for example, It can also be used as an attachment device for attaching a book stand to a display (liquid crystal display unit) of a portable word processor (word processor).
[0043]
【The invention's effect】
According to the first aspect of the present invention, in addition to holding the mounting partner between the locking portion and the pressing portion, the support surface portion is supported by the mounting partner, so that the clamping is simply performed like a conventional clip. Compared to the above, the mounting stability can be improved. Furthermore, since the conventional clip can clamp the mounting partner only at the tip, the pinching is unstable, but it opens and closes by moving the pressing part parallel to the locking part. And the entire pressing portion can be clamped, and a stable clamping state can be secured. The pressing portions provided at the tips of the two arms are positioned in the width direction of the locking portion, so that the clamping stability with respect to the mounting partner can be ensured, and the locking portion and the pressing portion are rotated by the rotation of the arm. It is possible to respond to changes in the thickness of the mounting counterpart by changing the interval. In addition, when mounting on a thin mounting partner, the support surface portion is insufficiently supported. However, the thinner the mounting partner is, the larger the leg opening angle of the arm is. Insufficient support can be compensated, and high mounting stability can be maintained even for thin mounting partners. By using multiple torsion coil springs and securing a predetermined biasing force against the arm, the number of turns of each torsion coil spring can be reduced to keep the spring height low and to prevent the mounting device from becoming large. Can do. In particular, the two torsion coil springs are narrowed by aligning the heights of the first torsion coil spring provided on the two arms and the second torsion coil spring provided between the two arms. It can be stored efficiently in the storage space.
[0044]
According to invention of Claim 2 , while being able to reinforce an arm with a rib, interference between torsion coil springs can be prevented.
[0045]
According to the third aspect of the present invention, when the mounting partner is used in a state inclined to the back side, the locking part is engaged with the front side of the mounting partner and is pivotally supported near the locking part. The center of gravity of the mounting body is positioned on the front side, and the long pressing part holds the mounting partner from the back side, so that the load of the mounted body on the back side can be reliably supported, and the back side of the mounting device Can be reliably prevented from falling off.
[0046]
According to the invention described in claim 4 , it is possible to improve the mounting stability of the image communication camera to the upper side surface portion of the display of the notebook personal computer.
