In addition, the shooting mode includes an auto shooting mode that automatically sets various settings such as exposure and focus, a manual shooting mode that is set by the user according to their preferences, and settings that are suitable for special shooting conditions. There are various shooting modes for.

  As a means for switching these plural modes, a mode switching dial for switching various modes by rotating the dial is often used because of its good operability.

  FIG. 8 shows a diagram of a conventional digital camera viewed from the back side (Patent Document 1). This digital camera is provided with a photographing lens (not shown) on the front side of the camera body 101 and a display unit 103 such as an LCD on the back side. A release button 104 and a mode switching dial 105 are provided on the upper surface of the camera body 101.

  When the camera is in the shooting mode, for example, the shooting lens protrudes from the storage position to the shooting position, and the subject image shot by pressing the release button 104 is displayed on the display unit 103 at any time. In the playback mode, it is recorded on a memory card or the like. A subject image is displayed on the display unit 103.

  The release button 104 is arranged at a position where the user can easily operate the camera while holding the camera body 101. The user sets the shooting angle of view while checking the subject on the display unit 103, and presses the release button 104 to shoot the subject image.

  The mode switching dial 105 is configured such that a part of the outer peripheral portion 105a is exposed on the back side of the camera body 101 so that the user can easily perform the rotation operation. Various mode icons are displayed on the mode switching dial 105, and the mode switching dial 105 is rotated so that an arbitrary icon matches an index provided on the camera body 101, thereby switching to a mode corresponding to the icon. be able to. The camera body 101 is provided with a click mechanism for stopping the rotation of the mode switching dial 105 at a position where the icon matches the index.

  The click mechanism of the mode switching dial 105 (hereinafter referred to as dial 105) is called a click leaf spring system. For example, as shown in FIG. 9, the click mechanism includes a dial attachment portion 101 a of the camera body 101, a contact attachment portion 107, a dial screw 108, a contact brush 109, a contact attachment screw 110, and a dial substrate 111.

  The dial mounting portion 101a is provided with a bearing portion 101b that rotatably supports the dial shaft 105b of the dial 105. Further, a leaf spring mounting portion 101c is provided so as to surround the periphery of the bearing portion 101b, and a click leaf spring 106 is disposed on the leaf spring mounting portion 101c. The click leaf spring 106 is formed by bending a belt-like leaf spring material into a substantially C shape, and has a convex portion 106a protruding radially outward at an intermediate portion in the circumferential direction.

  An uneven click portion 105c is provided on the inner peripheral portion of the dial 105. When the dial 105 is rotated, the click portion 105c has a convex portion 106a of the click leaf spring 106 at every predetermined rotation angle. It is designed to engage elastically. Thereby, the rotation angle position of the dial 105 is held for each predetermined rotation angle.

  A screw hole 105d is provided at the tip of the dial shaft 105b, and a contact mounting portion 107 is provided in the screw hole 105d so as to abut on the inner surface side of the camera body 101. Then, the contact brush 109 is attached to the screw hole 107 a of the contact attaching portion 107 by the contact attaching screw 110.

  The contact brush 109 is provided so as to be in contact with the dial substrate 111, and when the dial 105 is rotated, the contact brush 109 rotates integrally with the contact mounting portion 107 around the dial shaft 105 b of the dial 105.

  The dial substrate 111 that contacts the contact brush 109 is provided with a conductive pattern 111 a at a position corresponding to the rotation path of the contact brush 109. The conductive pattern 111a has a plurality of divided arc-shaped patterns, and when the dial 105 is rotated by the plurality of divided arc-shaped patterns, the contact is switched for each predetermined rotation angle position. It becomes possible.

  As described above, the click leaf spring 106 has the convex portions 106a projecting radially outward at the intermediate portion in the circumferential direction, and approximately C toward the tip portions 106b and 106c on both sides of the convex portion 106a. Curved portions 106d and 106e bent in a letter shape are arranged (see FIG. 10).

  As shown in FIG. 11, the dial mounting portion 101a is provided with a contact portion 101d extending in a substantially T shape from the bearing portion 101b to the back side of the camera body 101. The dial mounting portion 101a is provided with a pair of arc-shaped ribs 101e and 101f spaced from each other in the circumferential direction around the bearing portion 101b on the front side of the camera body 101.

  Then, as shown in FIG. 11, the front end portions 106b and 106c of the click leaf spring 106 are brought into contact with the contact portion 101d, and the convex portion 106a is pushed downward in FIG. 11 (the back side of the camera body 101). It is assembled between the pair of ribs 101e and 101f of the dial mounting portion 101a.

  In such an assembled state, the curved portions 106d and 106e of the click leaf spring 106 are bent, and a force is generated to push the convex portion 106a upward in FIG. 11 (the front side of the camera body 101).

  In this state, as shown in FIG. 12, when the dial 105 is assembled, the convex portion 106a engages with the concave portion 105e of the click portion 105c on the inner peripheral surface of the dial 105 and is sandwiched between the ribs 101e and 101f. Become. As a result, the dial 105 can be held stationary.

  In this state, as shown in FIG. 13, when the dial 105 is rotated in the direction of the arrow (counterclockwise in FIG. 13), the portion of the dial 105 that contacts the convex portion 106a of the click plate spring 106 becomes the concave portion 105e. Transitions from to the convex portion 105f. During this transition, the convex portion 106a of the click leaf spring 106 is pushed further downward (on the back side of the camera body 101).

  Therefore, the curved portions 106d and 106e of the click leaf spring 106 are further curved to generate a stronger pushing back force against the convex portion 106a, thereby generating a resistance force for returning the rotation of the dial 105.

  When the dial 105 is further rotated against this resistance force, the dial 105 is rotated by the force of pushing back the convex portion 106a while the portion of the dial 105 that contacts the convex portion 106a transitions from the convex portion 105f to the concave portion 105g. The power to promote arises. A click force can be obtained when the dial 105 is rotated by the action of switching between the resistance force and the acceleration force.

  FIG. 14 shows another conventional click mechanism of the mode switching dial (Patent Document 2). In this click mechanism, a plurality of click holes 205a are provided in the contact brush 205, a recess 203a is provided inside the dial mounting portion 203, and a steel ball 204 is disposed in the recess 203a.

  A click function is provided by the action of one of the plurality of click holes 205 a engaging with the steel ball 204 by the rotation of the dial 201 disposed at the upper rear side of the camera body 202.

The click mechanism is not arranged inside the dial like the click mechanism shown in FIGS. 12 and 13, and the contact brush 205 also serves as the click mechanism. Accordingly, there is a degree of freedom in the size and design of the dial shape, but the dial cannot be rotated all around. Further, since the click torque is obtained by the engagement between the click hole 205a and the steel ball 204, the torque is weak, the contact contact due to the click vibration is unstable, and the brush outer diameter inside the camera tends to be large.

  By the way, in particular, in general small digital cameras, in order to protect the photographing lens from external pressure and impact and at the same time maintain the compactness as a device, the photographing lens is often retracted and stored in the camera body when not photographing.

  For this reason, when the digital camera is housed in a bag, etc., the mode switching dial is rotated inadvertently so that the mode is switched and the photographing lens does not protrude from the stowed position to the photographing position and is susceptible to external pressure. It is necessary to avoid it.

  In this case, the dial 105 adopting the click leaf spring system shown in FIGS. 12 and 13 can maintain the rotation torque of the dial more appropriately than the dial 201 shown in FIG. This is advantageous in avoiding rotation.

  However, in the dial 105 employing the so-called click leaf spring method shown in FIGS. 12 and 13, it is difficult to reduce the diameter of the dial due to the downsizing of the digital camera.

  That is, if the click plate spring 106 is thinned in accordance with the diameter reduction of the dial 105, the pushing back force of the convex portion 106a is weakened, and a sufficient click force cannot be obtained.

  On the other hand, if the diameter of the dial 105 is reduced while the plate thickness of the click leaf spring 106 is kept as it is, excessive bending stress is generated in the curved portions 106d and 106e, causing spring breakage. In order to avoid this spring breakage, it is necessary to reduce the unevenness of the click part 105c of the dial 105, and the click force tends to become unstable.

  Therefore, an object of the present invention is to provide an electronic device that can obtain a sufficient and stable click force even when the diameter of the dial is reduced, and can avoid inadvertent rotation of the dial.

In order to achieve the above object, an electronic device of the present invention is attached to a dial having an uneven click portion on an inner peripheral portion, a bearing portion that rotatably supports the dial, and the periphery of the bearing portion. A curved portion, a convex portion protruding radially outward from the curved portion and elastically engaging with the click portion, and a spring member having a bent portion formed between the convex portion and the curved portion. In the electronic device comprising, in the region of the bearing portion facing the bent portion of the spring member attached around the bearing portion, the radial thickness of the spring member attached around the bearing portion A thin portion that is thinner than a radial thickness in a region of the bearing portion facing the curved portion is formed .

  According to the electronic device of the present invention, a sufficient and stable click torque can be obtained even if the dial is reduced in diameter, so that inadvertent rotation of the dial can be avoided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The dial mounting portion 1b is provided with a pair of arc-shaped ribs 1h and 1i spaced apart from each other in the circumferential direction around a bearing portion 1c facing the upper side of the camera body 1.

  Then, with the click leaf spring 8 being in contact with the abutting portion 1g with the tip end portions 8b and 8c being in contact with the abutting portion 1g, the dial mounting portion 1b is pushed while pushing the convex portion 8a downward in FIG. It is assembled between the pair of ribs 1h and 1i.

  In such an assembled state, the curved portions 8d and 8e of the click leaf spring 8 are curved, and a force is generated to push the convex portion 8a upward in FIG. 4 (upper side of the camera body 1).

  In this state, when the dial 7 is incorporated in the bearing portion 1c, the convex portion 8a engages with the click portion 7d on the inner peripheral surface of the dial 7 and is sandwiched between the ribs 1h and 1i. Can be held stationary. The ribs 1h and 1i are located between the dial 7 and the bent portions 8f and 8g of the click plate spring 8.

It has been. Thereby, it is avoided that the storage space of the click leaf | plate spring 8 becomes narrow because the diameter of the dial 7 was reduced. Further, the thin portion 1 e is arranged in a direction that substantially coincides with the direction in which the outer peripheral portion 7 a of the dial 7 is exposed on the upper surface side of the camera body 1.

  A reinforcing convex portion 1 f that protrudes toward the convex portion 8 a is provided on the outer peripheral surface of the bearing portion 1 c and facing the convex portion 8 a of the click leaf spring 8. The thin portions 1e described above are disposed on both sides of the reinforcing projection 1f in the circumferential direction. The reinforcing convex portion 1f protrudes radially outward from the diameter of the bearing portion 1c in a region other than the thin portion 1e within a range not interfering with the convex portion 8a, and compensates for insufficient strength of the bearing portion 1c due to the thin portion 1e. ing.

  Next, an operation example of the click mechanism when the dial 7 is rotated will be described.

  The user holds the grip part 4 of the camera body 1 with the right hand, presses the outer peripheral part 7a of the dial 7 exposed on the upper surface side of the camera main body 1 with an index finger, and rotates the dial 7 in the tangential direction of the outer peripheral part 7a. Rotate in the direction of the arrow in FIG.

  When the dial 7 is rotated in the direction of the arrow in FIG. 4, as shown in FIG. 5, while the portion that contacts the convex portion 8 a of the click plate spring 8 of the dial 7 changes from the concave portion 7 f to the convex portion 7 g, the convex portion 8 a. Is pushed further downward (below the camera body 1). Therefore, the curved portions 8d and 8e of the click leaf spring 8 are further curved to generate a stronger pushing back force against the convex portion 8a, thereby generating a resistance force for returning the rotation of the dial 7.

  At this time, the convex portion 8a of the click leaf spring 8 is pushed downward (below the camera body 1), and the bent portions 8f and 8g between the convex portion 8 and the curved portions 8d and 8e approach the bearing portion 1c.

A click force can be obtained when the dial 7 is rotated by the action of switching between the accelerating force and the above-described resistance force.

  As described above, in the present embodiment, the thin portion 1e is provided on the outer peripheral surface of the bearing portion 1c in the region facing the bent portions 8f and 8g of the click leaf spring 8, so that the diameter of the dial 7 can be reduced. The click leaf spring 8 can be accommodated in the dial mounting portion 1b while ensuring the necessary size.

  Thereby, even if the diameter of the dial 7 is reduced, a sufficient and stable click force can be obtained, and inadvertent rotation of the dial 7 can be avoided.

  Moreover, in this embodiment, since the reinforcement convex part 1f is provided in the part facing the convex part 8a of the thin part 1e, and the intensity | strength lack of the bearing part 1c by the thin part 1e is reinforced, the dial 7 is strong force. Even if pushed, sufficient strength and durability can be secured for the bearing portion 1c.

  Furthermore, in the present embodiment, the reinforcing convex portion 1f is protruded radially outward from the diameter of the bearing portion 1c in the region other than the thin portion 1e within a range not interfering with the convex portion 8a. For this reason, since the reinforcement convex part 1f is provided using the range which does not interfere with the convex part 8a to the maximum, the insufficient strength of the bearing part 1c by the thin part 1e can be reliably reinforced.

Is pushed further downward (below the camera body 1). Therefore, the curved portions 8d and 8e of the click leaf spring 8 are further curved to generate a stronger pushing back force against the convex portion 8a, thereby generating a resistance force for returning the rotation of the dial 7.

  At this time, the convex portion 8a of the click leaf spring 8 is pushed downward (below the camera body 1), and the bent portions 8f and 8g between the convex portion 8 and the curved portions 8d and 8e approach the bearing portion 1c.
