DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment)
FIG. 1 shows 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, 5 is a display unit, and 6 is a display unit. A shutter button 7 is a latch unit.

  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.

  In the biaxial hinge portion, the rotation axis of the first hinge portion that couples the display block 2 to the lens block 1 and the rotation axis of the second hinge portion that joins the frame block 3 to the lens block 1 are orthogonal to each other.

Further, as shown in FIG. 1B, the frame block 3 rotates about the rotation axis of the second hinge portion with respect to the lens block 1 and the display block 2.
Further, as shown in FIG. 1C, the display block 2 rotates about the rotation axis of the first hinge portion with respect to the lens block 1.

Specifically, the frame block 3 is rotated 360 degrees, and shooting in various styles can be performed by changing the angle of the frame block 3 during use.
First, as shown in FIG. 1A, in a state where the periphery of the lens block 1 and the display block 2 is covered with the frame block 3, shooting can be performed in a normal camera style.

Further, as shown in FIG. 1B, the frame block 3 can be gripped and photographing can be performed even if it is held like a camcorder.
Further, as shown in FIG. 1 (d), the frame block 3 can be opened to take a picture like a tripod stand.
Note that the U-shaped frame shape of the frame block 3 can be used to shoot on a hook such as a wall surface.

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 of the first hinge portion.

That is, on the side opposite to the lens block 1, the display block 2 and the frame block 3 are held in an 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.

Then, as shown in FIG. 1C, when the display block 2 is rotated with respect to the lens block 1 around the rotation axis of the first hinge portion, the latch is placed on the extension line of the rotation axis of the first hinge portion. Since the locked state is maintained by the portion 7, 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.

  Next, FIG. 2 shows the structure of the frame block 3, 8 is a frame block main body member, and 9 is a frame block end member.

As illustrated, the frame block 3 includes a frame block body member 8 and frame block end members 9 that are detachably connected to both ends of the frame block body member 8.
The frame block end member 9 is rotatably connected to the lens block 1 via the second hinge portion.

The frame block body member 8 includes a grip frame 81 made of a metal part (for example, a strength part such as stainless steel) and a grip case 82 made of a resin material that covers the outer peripheral side except for both ends of the grip frame 81. .
An FPC (flexible circuit board) 83 is stacked on the outer periphery of the grip frame 81, and FPC pressers 84 that are fixed to both ends of the grip frame 81 with the FPC 83 interposed therebetween are provided.

Further, at both ends of the grip frame 81, a notch groove 81a opened at the tip, a round hole 81b continuing to the notch groove 81a, and an inner slope 81c are formed.
Further, the FPC presser 84 is also provided with a notch groove 84 a corresponding to the notch groove 81 a of the grip frame 81.

  FIG. 3 is an enlarged view of an end portion of the FPC 83. A notch groove 83a corresponding to the notch groove 81a of the grip frame 81 is formed at the end portion of the FPC 83, and a pair of electrode patterns 85 of the mounted circuit is formed. Are formed.

  FIG. 4 shows the structure of the frame block end member 9 and the second hinge portion. 11 is a hinge shaft, 12 is a crimping part, 13 is an FPC, 14 is an FPC presser, 15 is a compression coil spring, and 19 is a fixing member. is there.

As shown in the figure, a cylindrical hinge shaft 11 made of a non-conductive material is provided on both sides of the lens block 1, and a pair of pins 19 a of a fixing member 19 provided inside the lens block 1 on a flange at the base end thereof. By inserting, it can be assembled with rotation stopped.
A cylindrical caulking component 12 is rotatably mounted on the outer periphery of the hinge shaft 11.

Further, an FPC 13 connected to a main circuit board (not shown) inside the lens block 1 is superimposed on the base end portion of the hinge shaft 11, and is fitted and fixed to a flange at the base end portion of the hinge shaft 11 with the PPC 13 interposed therebetween. An FPC presser 14 is provided.
Further, the compression shaft spring 15 is interposed between the FPC presser 14 and the fixing member 19, and the flanges at the base end portions of the hinge shaft 11 and the caulking part 12 are incorporated into the lens block 1 (see FIG. 6).

The frame block end member 9 includes a hinge movable portion 91 (see FIG. 5A) that is fixed by caulking to the flange at the tip of the crimping component 12, and a resin component that covers the outside of the hinge movable portion 91. It is comprised from the grip case 92 by.
A push button 93 made of a resin component is assembled to the grip case 92. That is, the push button 93 is screwed and fixed inside the grip case 92 and is disposed in a window portion 92 a formed in the grip case 92.

  Further, the push button 93 is provided with a protrusion 93a protruding inward.

In addition, inside the cylindrical hinge shaft 11 made of a non-conductive material, as shown in FIGS. 5A and 6B, the round bar-shaped conductor 16 located at the center and the hinge shaft 11 An annular conductor 17 in contact with the inner periphery and an annular non-conductor 18 interposed between the conductors 16 and 17 are integrated and integrated.
The conductors 16 and 17 are respectively connected to contacts (not shown) that form pairs of electrode patterns of the FPC 13.

  Here, as an integrated part manufacturing method of the hinge shaft 11, the material of the conductor 16 and the conductor 17 is made of a high-strength material such as SUS, and the hinge shaft 11 and the non-conductor 18 are made of, for example, PPS. A four-layer structure as shown in the figure is produced by integrally molding with a high-strength resin.

  Alternatively, in order to ensure the strength of the outermost hinge shaft 11, for example, metal cutting or die casting is performed, and the conductor 17 is insulated around the conductor 17, the conductor 17, the non-conductor 18. An integrated part is made by inserting or the like. In this case, a five-layer structure is used.

Alternatively, the outermost hinge shaft 11 and the conductor 17 are made of, for example, the same material (metal), and are integrally formed with the conductor 16 and the non-conductor 18.
Thereby, since the outermost part is in contact with the metal part, it can be used as GND and the conductor 16 can be used as a signal line. In this case, a triple structure is formed.
In addition, several types of manufacturing methods are conceivable.

In the frame block end member 9 and the second hinge portion described above, the hinge movable portion 91 rotates around the hinge shaft 11 together with the caulking part 12 having the flange fixed by caulking.
The hinge shaft 11 is biased in the protruding direction by a compression coil spring 15 between the FPC presser 14 and the fixing member 19.
Therefore, the tip of the hinge shaft 11 is in a protruding state on the outside of the hinge movable portion 91 as shown in FIG.

  FIGS. 5B to 5D illustrate how to connect the grip frame 81 of the frame block main body member 8 to the hinge movable portion 91 of the frame block end member 9.

As shown in FIG. 5 (b), when the grip frame 81 is inserted into the slide guide portion of the hinge movable portion 91 and is slid, the tip slope 81c of the grip frame 81 is moved as shown in FIG. 5 (c). Riding on the tip of the hinge shaft 11, the hinge shaft 11 is pushed in against the bias of the compression coil spring 15.
As shown in FIG. 5D, when the grip frame 81 is slid to the innermost part of the slide guide portion of the hinge movable portion 91, the hinge is biased by the compression coil spring 15 in the round hole 81b at the tip of the grip frame 81. The tip of the shaft 11 protrudes and enters a locked state.

  At this time, the protrusion 93a of the push button 93 is located inside the notch grooves 81a, 83a, and 84a at the ends of the grip frame 81, the FPC 83, and the FPC presser 84.

  In the above connection state, the contact 86 of the FPC 83 at the tip of the grip frame 81 is electrically connected to the conductor 16 at the center of the hinge shaft 11, and the contact 87 of the FPC 83 is electrically connected to the conductor 17 on the inner periphery of the hinge shaft 11.

That is, the FPC 83 fixed to the grip frame 81 slides while being in contact with the conductors 16 and 17 in the hinge shaft 11 as the frame block 3 rotates.
Since the contact point 86 of the FPC 83 of the grip frame 81 and the conductor 16 of the hinge shaft 11 are concentric circles, they are always in contact even when the frame block 3 rotates.
Further, since the conductor 17 on the inner periphery of the hinge shaft 11 is annular, the contact 87 of the FPC 83 of the grip frame 81 is always in contact with the conductor 17 on the inner periphery of the hinge shaft 11 during rotation.

  Although the FPC 13 fixed to the hinge shaft 11 of the lens block 1 has the same structure, since it does not rotate, the paired contacts are always in electrical contact with the conductors 16 and 17, respectively.

Further, when the frame block body member 8 is removed, the push button 93 of the frame block end member 9 is pushed in the direction of arrow A as shown in FIGS. Thus, the hinge shaft 11 is retracted against the bias of the compression coil spring 15.
Thereby, the lock | rock of the hinge shaft 11 front-end | tip with respect to the round hole 81b of the front-end | tip of the grip frame 81 is cancelled | released, and the grip frame 81, ie, the frame block main body member 8, can be extracted.

  As described above, since the lens block 1 and the frame block 3 can be electrically connected, the following functions can be added to the frame block 3.

  For example, as shown in FIG. 7, the zoom key 31 is installed on the frame block main body member 8.

  Further, by connecting the FPC 83 of the frame block 3 to both sides of the lens block 1, for example, as shown in FIG. 8, the access point search using a wireless LAN or the like can be performed by pressing, which also serves as a strap threading member. It is also possible to add a plurality of functions by providing a key 32 for execution, etc., and electrically connecting the contact 33 to the FPC 83.

  Further, for example, the frame block 3 which does not require an electrical element such as an attachment fixed to a bicycle can be attached and detached as a dressing part with various patterns.

  As described above, the frame block 3 is a frame block end member coupled to the lens block 1 via the hinge shaft 11 even in a camera having many movable parts including the lens block 1, the display block 2, and the frame block 3. Since the frame block body member 8 is detachably connected to the frame 9, the frame block body member 8 can be connected to the frame block end member 9 and securely locked.

  And since the circuit which can be connected with the circuit board inside the lens block 1 is provided in the inside of the frame block main body member 8, a function can be added.

  In other words, the physical attachment / detachment of the frame block 3 to / from the lens block 1 of the camera can be performed, so that it is possible to change parts of different colors, or to attach an attachment for fixing a bicycle, for example.

Further, since the lens block 1 and the frame block 3 can be electrically connected, the frame block 3 can have functions such as the zoom key 31 and the key 32.
As described above, the commercial value as a camera can be improved.
