[0027]
When using the camera of the mobile terminal body 1 with a camera, first, the folded housing display unit 5 and the housing operation unit 7 of FIGS. 4 and 5 are opened as shown in FIG. By manually sliding the open / close knob 29 to the open side indicated by the arrow in FIG. 8, the second arm portion 19 and the first arm portion 17 are swung through the interlocking member 28 and the convex portion 18. Further, the lens cover 12 is moved to the non-sliding side of the opening / closing knob 29 through the slider 14 by swinging the first arm portion 17 to expose the lens 2 and the mirror 3. At the same time, in conjunction with the movement of the open / close knob 29 to the open side, the internal program circuit (not shown) is switched from the incoming call waiting mode in a state of waiting for communication such as a telephone to the camera mode enabling photographing. When the lens 2 is pointed at the object to be photographed and the center key 6a serving as a shutter button is pressed, photographing can be performed. Here, when the open / close knob 29 of the open / close operation portion 27 is manually slid to the open side, the convex portion 18 slides on the closing side extending portion 20a of the spring 22, and the movement position of the convex portion 18 is bent. When the point 20c is exceeded, the convex portion 18 is slid to the end side of the open-side extending portion 20b by the elastic force of the spring 22, and the second arm portion 19, the first arm portion 17 and the lens cover 12 are all moved. It surpasses to the open side (state of FIG. 9) . If the sliding of the opening / closing knob 29 is stopped when the movement position of the convex portion 18 does not exceed the bending point 20c, the convex portion 18 reverses the closing side extending portion 20a of the spring 22 by the elastic force of the spring 22. The second arm portion 19, the first arm portion 17 and the lens cover 12 are returned to the fully closed side via the convex portion 18.
[0028]
When the camera of the camera-equipped mobile terminal body 1 is not used, the opening / closing knob 29 of the opening / closing operation unit 27 is manually slid to the closing side indicated by the arrow in FIG. The second arm portion 19 and the first arm portion 17 are swung in the opposite directions, and the lens cover 12 is moved in the opposite direction of the opening / closing knob 29 via the slider 14 by the reverse swing of the first arm portion 17. The lens is moved to the slide side to close the open window 11 and cover the lens 2 and the mirror 3. At the same time, in conjunction with the movement of the lens cover 12 to the closing side, an internal program circuit (not shown) is switched from a camera mode enabling photographing to an incoming call waiting mode for waiting for communication such as a telephone call. And make it possible to use communication equipment such as telephones. When all the processes are completed, the housing display unit 5 and the housing operation unit 7 are folded. Here, when the open / close knob 29 of the open / close operation part 27 is manually slid to the closing side, the convex part 18 slides on the open side extension part 20b of the spring 22, and the movement position of the convex part 18 is bent. When the point 20c is exceeded, the convex portion 18 is slid to the end side of the closing side extending portion 20a by the elastic force of the spring 22, and the second arm portion 19, the first arm portion 17 and the lens cover 12 are all moved. Surpass to the closing side. If the sliding of the opening / closing knob 29 is stopped when the movement position of the convex portion 18 does not exceed the bending point 20 c, the convex portion 18 reverses the open side extending portion 20 b of the spring 22 by the elastic force of the spring 22. The second arm portion 19, the first arm portion 17 and the lens cover 12 are returned to the fully open side via the convex portion 18.
[0029]
In the above description, since the lens cover 12 is formed of the sheet metal 12a, the lens 2 and the mirror 3 can be protected against an impact or the like when the camera-equipped mobile terminal body 1 is dropped, and the strength thereof can be increased.
[0030]
Further, a ground metal plate 34 made of a conductive leaf spring material is disposed between the resin slider 14 and the lens cover 12, and the ground metal plate 34 made of the leaf spring material is opened and closed by its elasticity. Since the drive pin 15 (ground terminal member 15a) of the mechanism 13 and the lens cover 12 are always in contact with each other, even when the mobile terminal body 1 enters an incoming call waiting mode in which it waits for communication such as a telephone call. Since the lens cover 12 is always connected to the ground portion GP and grounded, even if the lens cover 12 of the sheet metal 12a is provided, the call sensitivity does not deteriorate, and good call quality can be ensured. Furthermore, since the ground metal plate 34 can be arranged at a narrow space between the resin slider 14 and the lens cover 12 by the metal plate 12a, the camera-equipped mobile terminal can be kept thin.
[0031]
The camera-equipped mobile terminal of the present invention is not limited to the illustrated example described above, and can be applied to a system in which the lens cover is moved directly with a finger to open and close, instead of manually driving the opening / closing drive mechanism. Needless to say, it may be driven electrically, and various changes can be made without departing from the scope of the present invention.
