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 of the camera body 32.
An electric cord 73 is drawn out from the lower portion of the back surface of the electronic device.

Next, the operation of this embodiment will be described.

When the CCD camera 12 is mounted on the display 13 of the notebook computer in the open state by this mounting device,
In FIG. 3 (A), the two leg portions 25 are pinched with a fingertip.
Two torsion coil springs 5 around the rotating shaft support 41
By rotating the two legs 25 in the direction B against the restoring force in the direction A of 1, 52, the two legs 25 are once opened with respect to the front plate 23, and as shown in FIG. A of the torsion coil springs 51 and 52 acting on the two legs 25 is fitted between the rear surface of the front plate 23 and the two legs 25 so that the upper sides of the open state display 13 are relatively inserted. When the repulsive biasing force (restoring force) in the direction is released, the CCD camera 12 can be mounted on 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.

At this time, the front plate 23 is engaged not only with the front side of the open state display 13 of the notebook computer, but also with the two legs 25 engaged with the back side of the display 13, and simultaneously with the bottom plate 22. The engagement stability of the CCD camera 12 is improved by engaging the upper side surface portion 21 of the CCD camera 13. That is, the display 13 comprises the front plate 23 and the legs 25.
By supporting the bottom plate 22 on the upper side surface of the display 13 in addition to the clamping, the mounting stability can be improved as compared with the conventional clip 2 (FIG. 7) which merely clamps.

In the conventional clip 2 (FIG. 7), the clipping is unstable because the clipping member can be clamped only at the distal end portion.
By pivoting in a plane parallel to 22, the two legs 25
Can be moved parallel to the front plate 23 at all times, so that the display 13 is held between the front surface of the front plate 23 and the entire length of the leg 25 even when the distance between the front plate 23 and the leg 25 changes. It is possible to obtain a stable sandwiching state.

For this reason, the thickness of the display 13 of the notebook computer can be accommodated in the range of the cutout portion 36 where the two legs 25 can freely rotate, and the display device 13 can be mounted on any display 13 of the notebook computer without any problem. It is possible.

At this time, the sandwiching can be stabilized by the two legs 25 provided in the width direction of the front plate 23. When the display 13 is mounted on a thin display 13, the support area on the bottom plate 22 is reduced.However, when the display 13 is thinner, the opening angle of the arm 24 is increased, and the interval between the two legs 25 is increased. Insufficient support by the bottom plate 22 can be compensated.

In addition, since the repulsive urging forces of the two torsion coil springs 51 and 52 act strongly on the two legs 25, the mounting stability can be improved by the repulsive urging forces. At this time, as shown in FIG. 3A, the first torsion coil spring 51 inserts both ends 54 and 55 into the ribs 46 and 47 of each arm 24 and inserts the pin 48 inside the rib 47. Front plate 23
Side, the second torsion coil spring 52 is
Since each arm 24 is urged toward the front plate 23 from the outside of 47, the torsion coil springs do not interfere with each other.

Further, as shown in FIG. 1, the present mounting device is used in a state where the display 13 of the notebook computer to be mounted is inclined to the back side, and a tilt shaft 34 provided near the front of the device main body 11. At this time, 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 located on the front side as much as possible, and the leg 25 for holding the display 13 from the back side is further moved from the front plate 23. Long form,
By tightly contacting the rear surface of the display 13, load support on the rear side of the display 13 is ensured, and it is possible to prevent the mounting device from dropping to the rear side of the display 13.

As described above, by setting the mounting position of the CCD camera 12 on the upper side of the display 13 in the open state, and by contacting the bottom plate 22 with the upper side surface 21 of the display 13, the mounting stability of the camera 12 is improved. And the rubber cylinder 28 fitted to the two legs 25, and the rubber plates 27, 29 attached to the back surface of the front plate 23 and the bottom plate 22 to improve the mounting stability. For example, the CCD camera 12 does not come off the display 13 of the notebook computer due to vibration.

Further, C after being attached to the display 13
The position of the CD camera 12 can be easily adjusted by the tilt mechanism in the front-rear direction, and the angle of the camera body 32 is adjusted in the front-rear direction about the tilt axis 34 so that the direction of the imaging window 71 of the CCD camera 12 in an appropriate direction. Can be set, and a correct beautiful image can be captured from the CCD camera 12.

The present invention is not limited only to the mounting device for mounting the CCD camera 12 on the display 13 of the notebook computer, but may be used as a mounting device for mounting another device on another device. For example, it can be used as a mounting device for mounting a reading stand on a display (liquid crystal display) of a portable word processor (word processor).

[0049]

According to the first aspect of the present invention, in addition to clamping the mating member by the locking portion and the pressing portion, the supporting surface portion is supported by the mating member. The mounting stability can be improved as compared with the case of simply sandwiching. Further, in the conventional clip, the clipping is unstable because the clip can be clamped only at the tip end. However, since the pressing portion is opened and closed by moving the pressing portion in parallel to the locking portion, the clipping portion is locked. And the entire pressing portion, and a stable holding state can be secured.

According to the second aspect of the present invention, the pressing portions provided at the tips of the two arms are located in the width direction of the locking portion, so that the holding stability against the mounting partner can be ensured. By changing the distance between the locking portion and the pressing portion by the rotation of the arm, it is possible to cope with a change in the thickness of the mounting partner. In addition, when mounting on a thin mounting counterpart, insufficient support occurs at the support surface. However, as the mounting counterpart becomes thinner, the leg opening angle of the arm increases. Insufficient support can be compensated for, and high mounting stability can be maintained even for thin mounting partners.

According to the third aspect of the present invention, the number of the torsion coil springs is reduced and the number of turns of each torsion coil spring is reduced while securing a predetermined urging force on the arm, thereby increasing the height of the spring. It can be held down and the size of the mounting device can be reduced.

According to the fourth aspect of the present invention, the first torsion coil spring provided on the two arms,
By aligning the height with the second torsion coil spring provided between the arms, the two torsion coil springs can be efficiently stored in a narrow storage space.

According to the fifth aspect of the present invention, the arm can be reinforced by the rib, and the interference between the torsion coil springs can be prevented.

According to the sixth aspect of the present invention, when the mounting partner is used in a state inclined to the rear side, the locking portion is engaged with the front side of the mounting counterpart to pivotally support the locking portion. The center of gravity of the mounted body is positioned on the front side, and the long pressing portion sandwiches the mounting partner from the back side, and can reliably support the load of the mounted body on the back side, and Dropping to the rear side can be reliably prevented.

According to the seventh aspect of the present invention, it is possible to improve the attachment stability of the image communication camera to the upper side of the display of the notebook personal computer.
