DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
1 and 2 show a camera as a configuration of an embodiment of an electronic apparatus to which the present invention is applied. 1 is a lens block, 2 is a display block, 3 is a frame block, 4 is a photographing lens, and 5 is a display unit. , 6 are shutter buttons.

  As shown in the figure, the camera housing includes a lens block 1 having a photographic lens 4, a display block 5 having a display unit 5 by liquid crystal display and a shutter button 6 arranged next to the display unit 5, and the two lens blocks 1 and the display. It is composed of three blocks including a frame block 3 formed in a U-shaped frame shape covering the periphery of the block 2.

A display block 2 and a frame block 3 are coupled to the lens block 1 via a biaxial hinge portion so as to be rotatable.
That is, the display block 2 is rotatably coupled to the lens block 1 via the first hinge portion, and the frame block 3 is rotatably coupled to the lens block 1 via the second hinge portion.

  As shown in FIG. 1, the biaxial hinge portion includes a rotation axis L1 of the first hinge portion that couples the display block 2 to the lens block 1 and a rotation axis line of the second hinge portion that joins the frame block 3 to the lens block 1. L2 are orthogonal to each other.

Therefore, as shown in FIG. 3, the display block 2 rotates about the rotation axis L <b> 1 of the first hinge portion with respect to the lens block 1.
Further, as shown in FIG. 4, the frame block 3 rotates about the rotation axis L <b> 2 of the second hinge portion with respect to the lens block 1 and the display block 2.

Specifically, the frame block 3 is rotated by 270 degrees, and shooting in various styles can be performed by changing the angle of the frame block 3 during use.
For example, the frame block 3 can be opened and photographed while standing like a tripod stand, or the frame block 3 can be hung on a hook such as a wall using the U-shaped frame shape, or the frame block 3 can be gripped to capture a camcorder. Shooting is possible even with such a way of holding (see FIG. 4).
Further, the frame block is provided with a strap passing member 31 that is formed of an elastic resin and allows the strap to pass therethrough (see FIG. 1). The strap passing member 31 functions to prevent slipping when the camera is set up like the tripod stand.

  In addition, when the frame block 3 covers the periphery of the lens block 1 and the display block 2, shooting can be performed in a normal camera style (see FIG. 2).

Here, when shooting with a normal camera style, when the shutter button 6 and other control keys are operated with the thumb, it is easy to apply a force to push the screen of the display block 2 or the display unit 5 with the finger during the operation.
At that time, in order to prevent the display block 2 and the frame block 3 from being blurred on the side opposite to the lens block 1, a latch portion 7 is provided that is located on an extension line of the rotation axis L <b> 1 of the first hinge portion.

As shown in FIGS. 5 and 6, the latch portion 7 includes a recess 72 provided in the display block 2, and a lock pin 73 and a lock spring 74 provided on the opposite side surface of the strap passage member 31 of the frame block 3. Has been.
That is, a hemispherical concave portion 72 whose center is located on the extension line of the rotation axis L1 of the first hinge portion is formed in the center of the end surface of the display block 2 opposite to the lens block 1.
In addition, a lock pin 73 whose tip is hemispherical at the center on the extension line of the rotation axis L1 of the first hinge part can be projected and retracted at the center of the inner surface of the end of the frame block 3 opposite to the lens block 1. In addition, a lock spring 74 that urges the lock pin 73 in the protruding direction is incorporated. The lock spring 74 is fixed so as to be in pressure contact with the lock pin 73 side by the strap threading member 31, and has a set load that secures a lock force greater than the operation force of the shutter button 6.

According to the latch portion 7 described above, the lock pin 73 protrudes by the urging force of the lock spring 74 and is kept in a locked state in which the lock pin 73 is engaged with the recess 72.
That is, on the side opposite to the lens block 1, the display block 2 and the frame block 3 are held in the engaged state by the latch portion 7, so that the shutter button 6 is operated in a normal camera style as shown in FIG. Even if the button is pressed, it is possible to prevent the display block 2 from being blurred and to perform good photographing.
Further, when other control keys are operated with the thumb, even when the screen of the display block 2 or the display unit 5 is pushed with the finger during the operation, the display block 2 can be prevented from being blurred.

As shown in FIG. 3, when the display block 2 is rotated with respect to the lens block 1 about the rotation axis L1 of the first hinge portion, the lock pin is on the extension line of the rotation axis L1 of the first hinge portion. Since 73 is kept in a locked state engaged with the recess 72, the clearance between the display block 2 and the frame block 3 is small and stable.
Therefore, a good appearance can be obtained as a camera casing constituted by three blocks.

  When the frame block 3 is rotated with respect to the lens block 1 and the display block 2 about the rotation axis L2 of the second hinge portion, a force greater than the shutter operation is applied to the display block 2 and the frame block 3 as shown in FIG. 8 and FIG. 8, the lock pin 73 is separated from the recess 72 against the bias of the lock spring 74, and the latch portion 7 is unlocked as shown in FIG. 9 and FIG. .

  Transition from the released state to the locked state of the latch unit 7 is performed in the reverse procedure.

(Modification)
In the above embodiment, the camera is used. However, the present invention is not limited to this, and may be an electronic device such as a mobile phone including the camera.
In the embodiment, the frame block 3 is rotatably coupled to the lens block 1, but the frame block 3 may be rotatably coupled to the display block 2. Even in this case, even when the screen of the display block 2 or the display unit 5 or the lens block 1 is pushed in with a finger during the operation, the lens block 1 (the photographic lens 4) can be prevented from being blurred.

Furthermore, in the embodiment, the display block is provided with a recess, and the frame block is provided with a movable protrusion to be a latch part. However, the display block is provided with a movable protrusion, and the frame block is provided with a recess to constitute a latch part. Also good.
Further, the shape of each block is arbitrary, and it is needless to say that other specific detailed structures can be appropriately changed.
