DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the drawings.
(Embodiment)
1 and 2 show a camera as a configuration of an embodiment of an electronic apparatus to which the present invention is applied. FIGS. 3 to 5 show arrows AA, BB, and CC in FIG. FIG. 6 to FIG. 9 are diagrams showing the interlocking mechanism of the light emitting unit and the reflecting unit, and FIG. 10 to FIG. 12 are diagrams showing the stoppers of the light emitting unit and the reflecting unit.

  In the figure, 1 is a camera body, 2 is a lens barrel, 3 is a strobe housing part, 4 is a strobe case, 5 is a strobe light emitting part, 6 is a reflecting part, 7 is a concave mirror, 8 is a stopper, 9 is an operation knob, 11 Is a first pinion, 12 is a second pinion, 13 is a rack bar, and 14 is a rack.

  As shown in the figure, the camera body 1 includes a lens barrel 2 at the front and a strobe storage unit 3 at the top. The strobe storage unit 3 stores the strobe case 4 and the reflection unit 6 in an interior opened upward.

  The strobe case 4 is incorporated in a rear portion of the strobe storage unit 3 so as to be able to be tilted up and down via a rotation shaft. The strobe case 4 includes a strobe light emitting portion 5 at the end opposite to the rotation shaft. That is, in the strobe light emitting unit 5, the direction in which the light is irradiated is variable from the front to the bottom as the strobe case 4 rotates about the rotation axis.

  Here, the power source for raising the strobe case 4 may be any type such as a coil spring or a motor. The configuration for starting the raising operation of the strobe case 4 may be any type such as manual release using a slide hook or automatic release using a solenoid.

  The reflection part 6 is rotatably incorporated in the front part in the strobe storage part 3 via a rotation shaft. The reflection unit 6 includes a concave mirror 7 that reflects the light from the strobe light emitting unit 5. Thus, the curved concave mirror 7 instead of the flat reflecting surface can reduce vignetting in the shape of the periphery of the strobe at the time of bounce shooting described later.

  The strobe storage unit 3 incorporates a stopper 8 that holds the strobe case 4 at a change position in the direction in which light is emitted from the strobe light emitting unit 5. The stopper 8 is integrally provided with an operation knob 9 that is exposed to the outside from one side of the strobe storage portion 3.

  Then, the first pinion 11 is provided integrally with the rotating shaft of the strobe case 4, the second pinion 12 is provided integrally with the rotating shaft of the reflecting portion 6, and the first pinion 11 and the second pinion 12 are provided. A rack bar 13 is stretched over. That is, the rack bar 13 has a rack 14 that meshes with the first pinion 11 along the upper surface, and a rack 14 that meshes with the second pinion 12 along the lower surface.

  Here, the rotation angle of the strobe case 4 and the reflecting portion 6 is adjusted by the different gear ratios of the first pinion 11 and the second pinion 12, so that the strobe light emitting unit is in a state before the strobe case 4 comes to stand upright. 5 is set so that the concave mirror 7 reflects the light irradiated by 5 upward.

  The strobe case 4 has a first regulating surface 41 that abuts against the stopper 8 in a state where the strobe case 4 stands vertically and a strobe case 4 that is rising up at an oblique angle. The 2nd control surface 42 contact | abutted to the stopper 8 in the state is formed. The second restriction surface 42 is set such that the distance from the rotation axis of the strobe case 4 is on the inner peripheral side of the first restriction surface 41.

  Next, the operation of the strobe lighting device having the above configuration will be described.

  FIGS. 1 to 6 and FIG. 10 show the storage of the strobe. At this time, the reflecting part 6 has the concave mirror 7 directed rearward.

  Here, the stopper 8 is adjusted in advance to a predetermined position by the operation knob 9 depending on whether the next shooting is bounce shooting or normal flash shooting. For example, when performing normal strobe shooting, the position of the stopper 8 is adjusted to a position where the strobe case 4 comes into contact with the first restricting surface 41 in a vertically upright state. When performing bounce shooting, the position of the stopper 8 is adjusted to a position where the strobe case 4 is in contact with the second restricting surface 42 in a state where the strobe case 4 is raised at an oblique angle.

  9, 12 and 13 show normal flash photography. That is, when a strobe pop-up switch (not shown) is operated, the strobe case 4 stored in the strobe storage portion 3 rotates integrally with the rotation shaft, and the first regulating surface 41 at the lower end thereof contacts the stopper 8, As shown in the figure, the strobe case 4 stands upright, and the strobe light emitting unit 5 is kept in the forward direction.

  At the same time, the rack bar 13 engaging the upper rack 14 with the first pinion 11 integral with the rotation shaft of the strobe case 4 moves forward, and the second pinion 12 engaging the rack 14 on the lower surface of the rack bar 13 rotates. The reflecting part 6 integrated with the moving shaft is rotated, and the concave mirror 7 is directed forward.

  In this state, when a shutter button (not shown) is pressed, as shown in FIG. 13, light is emitted from the strobe light emitting unit 5 facing forward at the same time, and normal strobe photography is performed.

  7, 11 and 16 show the bounce shooting. That is, when a bounce switch (not shown) is operated, the strobe case 4 stored in the strobe storage portion 3 rotates integrally with the rotation shaft, and the second regulating surface 42 at the lower end thereof contacts the stopper 8, As described above, the strobe light emitting section 5 is kept obliquely forward and downward in an oblique state while the strobe case 4 is raised.

  At the same time, the rack bar 13 engaging the upper rack 14 with the first pinion 11 integral with the rotation shaft of the strobe case 4 moves forward, and the second pinion 12 engaging the rack 14 on the lower surface of the rack bar 13 rotates. The reflecting part 6 integrated with the moving shaft is rotated, and the concave mirror 7 is directed upward.

  In this state, when a shutter button (not shown) is pressed, as shown in FIG. 16, the light emitted from the strobe light emitting unit 5 obliquely facing forward and downward is reflected upward by the concave mirror 7 and is reflected on the ceiling (not shown). Bounce shooting is performed by reflecting the light indirectly on the subject after reflection.

  As described above, in a camera equipped with a strobe, bounce photography can be performed without adding an external strobe.

(Modification)
FIG. 14 and FIG. 15 show modifications at the time of bounce shooting. That is, the bounce light emission state at two positions where the rising angle of the strobe light emitting unit 5 is small is shown. The third restriction surface and the fourth restriction surface that contact the stopper 8 while the strobe case 4 is rising at an oblique angle. A surface is formed. The third restricting surface and the fourth restricting surface are set so that the distance from the rotation axis of the strobe case 4 sequentially comes to the inner peripheral side of the second restricting surface 42.

(Other variations)
In the above embodiment, the camera is used. However, the present invention is not limited to this, and may be a device such as a mobile phone including the camera.
Further, the shape and configuration of the light emitting part and the reflecting part are arbitrary, and it is needless to say that other specific detailed structures can be appropriately changed.
