Description

  The present invention relates to an electronic device having an operation member that can rotate with respect to a device main body.

  Conventionally, in an imaging apparatus such as a digital still camera or a video camera, an optical zoom function for changing a magnification by moving a part of a lens of a photographing optical system on an optical axis, and an image signal from an image sensor are electronically transmitted. Some have an electronic zoom function that is controlled to perform enlarged display of the screen.

  In addition, when using the optical and electronic zoom functions, such an image pickup apparatus performs an optical and electronic zoom operation by rotating an operation member that can rotate with respect to the apparatus body, for example, a zoom lever. . The configuration in which the zoom lever is rotated to perform the zoom operation is different from the configuration in which different buttons are operated when the zoom magnification is changed to the wide-angle side and when the zoom magnification is changed to the telephoto side. Widely used because it allows easy zooming while checking.

  Such a zoom lever is held at the initial position (neutral position) when not operated, and when the user operates in one direction from the initial position, the zoom magnification can be changed to the wide angle side. By operating in the direction, the zoom magnification can be changed to the telephoto side. When the user stops the operation of the zoom lever and the zoom lever returns from the rotation position to the initial position, the zoom magnification is not changed and the zoom magnification at that time is maintained. Since the zoom magnification is changed by the above operation, the zoom lever is required to have a clear operational feeling in order to accurately reflect the user's intention. Therefore, conventionally, an operation member that can be rotated with respect to the apparatus main body such as a zoom lever has often used a spring load of a coil spring that can easily manage an operation load and a return load.

  For example, in Patent Document 1, a coil spring is arranged outside the projection surface of the zoom lever when viewed from the top of the digital camera, and a boss provided with a female screw on the base member is prepared for fixing, and a flange portion of the base member and the screw is prepared. It is the structure fixed by pinching a coil spring.

  Further, in Patent Document 2, a coil spring is attached to a zoom lever and a zoom holder that rotates integrally with the zoom lever, so that the coil spring is disposed in the projection surface of the zoom lever as viewed from the top surface of the digital camera. Yes.

The brush 45 rotates integrally with the zoom lever 40, and is at positions R (initial position), S (when rotated clockwise), and T (when rotated counterclockwise) in the drawing. It is movable. Each pattern can be short-circuited by moving to positions R, S, and T in the figure.

  Next, the assembly of the upper surface base member 43 will be described in detail with reference to FIGS. 4, 5, and 6.

  First, the coil spring end turn 12a is attached to a hollow inner circumference regulating shaft 43c provided on the lower surface of the upper surface base member 43. At this time, one of the arm portions 12b of the coil spring is hooked on the fitting portion 43eb provided on the outer periphery regulating rib 43e of the upper surface base member 43, and is assembled so as to be clamped by the flange portion 43ea provided on the outer periphery regulating rib 43e. . In this state, the end winding portion 12a of the coil spring is sandwiched by one of the flange portions 43ca and 43ea provided on the lower surface of the upper surface base member 43.

  Then, the other arm portion 12b of the coil spring is moved in the direction of the arrow X, and the fitting portion 43eb is sandwiched and assembled. At this time, the coil spring 12 is charged and the end turn part 12a is compressed to reduce the inner diameter. Therefore, an urging force in the rotational direction is generated in the arm portion 12b of the coil spring to return to the state before charging, and the end winding portion 12a is compressed and the inner diameter is reduced. The In this way, the coil spring 12 is configured not to drop off from the upper surface base member 43. Further, the coil spring end winding portion 12a is further charged by the operation of the zoom lever 40 to reduce the inner diameter, but even in this state, an appropriate clearance is provided so as not to interfere with the inner peripheral regulating shaft 43c of the upper surface base member 43. Is secured. As described above, the end winding portion 12a of the coil spring passes between the inner circumference regulating shaft 43c and the outer circumference regulating rib 43e.

  Next, a state where the zoom lever 40 is assembled to the upper surface base member 43 will be described with reference to FIG. FIG. 5A shows the state in which the two shafts 40b and the coil spring mounting shaft 40g extending in the lower direction of the zoom lever 40 are inserted into the fan-shaped through holes 43b and 43g of the upper surface base member 43. It is the figure seen from the lower surface side of 43. FIG. 5 (b) shows a detailed cross-sectional view in the vicinity of the coil spring mounting shaft 40g.

It becomes a state. At this time, since the ribs 40gd are provided on both sides of the coil spring mounting shaft 40g, when the zoom lever fixing member 44 is applied, the arm portion 12b of the coil spring is formed on the contact surface between the fitting portion 40gb and the zoom lever fixing member 44. Moving in the direction of arrow Y is prevented. Thus, the zoom lever fixing member 44 is applied from the lower side so that the upper surface base member 43 is sandwiched so that the arm portion 12b of the coil spring does not climb on the contact surface.

  The ends of the shaft 40b and the coil spring mounting shaft 40g are inserted into the holes 44b and 44ca of the zoom lever fixing member 44, respectively, and the conical portions 40ba and 40ga for caulking are crushed to integrate the zoom lever 40 and the zoom lever fixing member 44. At this time, the arm portion 12 b of the coil spring is held between the holding portion provided on the zoom lever 40 and the beam portion 44 c of the zoom lever fixing member 44.

  The inner circumference regulating shaft 43c and the outer circumference regulating rib 43e extend into the hole 44a of the zoom lever fixing member 44, and the flange 43ca of the inner circumference regulating shaft 43c faces the outer circumference of the hole 44a. The flange portion 43ea of the outer periphery regulating rib 43e faces the center side of the hole portion 44a. In other words, the tip of the inner periphery regulating shaft 43c protrudes toward the outer periphery of the hole 44a, and the tip of the outer periphery restriction rib 43e protrudes toward the center of the hole 44a. Further, the inner peripheral restriction shaft 43c is disposed closer to the center of the hole 44a than the outer peripheral restriction rib 43e.

  The completed zoom lever unit 4 is assembled from the rotation axis direction of the zoom lever 40 so that the positioning hole 43f is inserted into the positioning pin 14a (see FIG. 1c) extending from the battery chamber 14. And it fixes by latching the protrusion part (not shown) provided in the battery chamber 14, and the arm part 43h provided in the upper surface base member 43. FIG. As described above, since the operation board 10 and the zoom lever unit 4 are both positioned by the positioning pins 14a provided in the battery chamber 14, the configuration is such that the displacement of each connecting portion is less likely to occur. By fixing the zoom lever unit 4 in this way, the upper surface base member 43 is fixed to the imaging apparatus main body 1.

  Next, the vertical size (thickness) of the zoom lever unit 4 will be described in detail with reference to FIG. As shown in FIG. 7B, the coil spring end winding portion 12a is restricted from moving in the radial direction of the coil spring 12 by the inner peripheral restriction shaft 43c and the outer peripheral restriction rib 43e provided on the upper surface base member 43, and the flange portion 43ca. 43ea, the movement in the vertical direction is restricted and held. Further, the arm portion 12 b of the coil spring is covered with the beam portion 44 c of the zoom lever fixing member 44, so that the operation board 10 disposed immediately below is not damaged.

  Since the zoom lever fixing member 44 is provided with a hole 44a having a diameter larger than the end winding portion of the coil spring 12 at a position including the rotation center, the end winding portion 12b of the coil spring and the zoom lever fixing member 44 are connected to each other. It can be arranged without shifting in the vertical direction. As described above, the end portion 12b of the coil spring is disposed inside the hole 44a of the zoom lever fixing member 44 so as to surround the rotation center of the zoom lever fixing member 44, so that the vertical size of the zoom lever unit 4 is increased. Can be made thinner.

  In addition, since the flanges 43ca and 43ea are formed on the upper surface base member 43, they do not move even when the zoom lever 40 is operated, and are not moved with respect to the operation board 10 arranged immediately below. There is no need to provide more vertical clearance than necessary. Rather, it is possible to make the operation substrate 10 a floating press by narrowing the vertical clearances of the flange portions 43ca and 43ea and the operation substrate 10 in consideration of the tolerance.

  With the configuration as described above, the zoom lever that can be rotated with respect to the main body of the image pickup apparatus can be urged in the rotation direction by the coil spring while suppressing the enlargement of the image pickup apparatus.

However, the present embodiment may be applied to other functions. For example, in a playback mode in which one of a plurality of images recorded on a recording medium is displayed on a liquid crystal display device (not shown), when changing the speed of an image feed operation for changing the displayed image to the next image. You may apply.

  In addition, since it can be applied to a function that can be executed by an electronic device other than the imaging device, such as the image feed operation described above, an operation member that can be rotated with respect to the device body is moved from the rotation position to the initial position by a coil spring. The present invention can be applied to any electronic device that is energized so as to return.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
