Description

  The present invention relates to a rotating device provided in various devices such as a camera, and more particularly to a rotating device that gives a click feeling when rotating a rotating body.

  A dial device that gives a click feeling by energizing a steel ball with a substantially disc-shaped plate spring and sequentially engaging the steel ball with a plurality of slits provided at the peripheral edge of the plate spring as the dial rotates is known. (See Patent Document 1).

  In such a dial device, when the engagement of the steel ball engaged with the slit is released, it is necessary to bend the leaf spring against the bias by the steel ball. More torque is required for dial operation than in the current state. On the contrary, when the steel ball is engaged with the slit, the steel ball is pushed into the slit by urging by the leaf spring, so that the torque required for the dial operation is reduced as compared with the state where the engagement is released. . A click feeling is given by the increase and decrease of the torque due to the deflection of the click plate.

The leaf spring is fixed to the main body or the dial member with a screw or the like.
JP-A-10-260465

  When the leaf spring is fixed to the main body or the dial member with a screw or the like, the fixing position functions as a fulcrum of the leaf spring. On the other hand, the number of screws for fixing the leaf spring is generally smaller than the number of engaging portions. For this reason, the engaging portion in the vicinity of the screw has a fulcrum position of the leaf spring on the peripheral side as compared with the engaging portion separated from the screw, and has a large force for deflecting the leaf spring by a predetermined amount.

Then, the protrusion 41a provided on the upper surface portion 2a side of the push button 41 and the retaining member 42 fitted from the inside of the housing of the upper surface portion 2a to the opening 21c are fixed, so that the push button 41 is dialed. It is fixed to the member 21. Between the dial member 21 and the push button 41, a spring 43 that urges the push button 41 toward the outside of the housing is disposed. When the push button 41 is pressed, the pressing switch 45 on the substrate 44 provided on the inner side of the housing from the upper surface portion 2 a is pressed by the retaining member 42.

  3 is an exploded front view of the dial device 3, FIG. 4 is an exploded perspective view of the dial device 3 seen from the back side of the upper surface portion 2a, and FIG. 5 is a perspective view of the dial device 3 seen from the back side of the upper surface portion 2a. FIG. However, in FIG. 3 to FIG. 5, some members such as the push button 41 are omitted. The dial device 3 includes a dial member 21, a steel ball 22 as an engaged body, a click plate 23 as an engagement plate spring, a contact plate 24 as a reinforcing plate spring, and a screw 25 as a fixing member. I have. In the dial device 3, the dial member 21 is attached to the upper surface portion 2 a from the outside of the housing, and the steel ball 22, the click plate 23, the contact plate 24, and the fixing member 25 are attached to the upper surface portion 2 a from the inside of the housing. Each member is attached in order.

  The dial member 21 is formed of a resin, for example, and includes a disk-shaped operation portion 21a and a shaft portion 21b that extends from the housing-side center of the operation portion 21a toward the housing. The dial member 21 is attached to the upper surface portion 2a so as to be rotatable about the rotation axis RA by inserting the shaft portion 21b into the opening 2b provided on the upper surface portion 2a from the outside of the housing. .

  The steel ball 22 has a spherical shape, is fitted into a concave spherical body holding portion 2c provided on the back surface of the upper surface portion 2a, and is rotatably held. The steel ball 22 partially protrudes from the back surface of the upper surface portion 2a.

  The click plate 23 is made of metal, for example. The click plate 23 is formed in a substantially disk shape. In other words, the click plate 23 extends radially from the rotation axis RA side. The click plate 23 has an inner peripheral part 23a on the rotation axis RA side and a peripheral part 23b on the outer peripheral side. A plurality of slit portions 23c (engagement portions) extending in the radial direction (direction from the rotation axis to the circumferential side) are provided at equal intervals in a range of about two thirds of the peripheral portion 23b. Is divided into a plurality of contact portions 23d by the slit portion 23c. The click plate 23 is provided so that the abutting portion 23d urges the steel ball 22 toward the upper surface portion 2a, and is provided so as to rotate integrally with the dial member 21. The steel ball 22 is sequentially engaged with the rotation of the member 21 with respect to the housing 2. Note that the remaining one-third range of the peripheral edge portion 23b is a support portion 23e for arranging a connection portion 24d described later.

  A slit portion 23 f (relaxation portion) that is continuous with the slit portion 23 c and extends in the circumferential direction (direction along the circumference) is provided on the outer peripheral side of the screw 25 in the peripheral edge portion 23 b. The slit portion 23f extends from the inner peripheral side end of the slit portion 23c to the fastening position side of the screw 25. In other words, the width of the connecting portion between the contact portion 23c and the inner peripheral portion 23a is formed narrower at the contact portion 23c at the fastening position of the screw 25 than at the contact portion 23c at the non-fastened position of the screw 25. Has been. For example, the width of the connecting portion between the abutting portion 23c at the fastening position of the screw 25 and the inner peripheral portion 23a may be about two-thirds of the connecting portion at the non-fastening position of the screw 25.

  The contact plate 24 is made of, for example, metal and is provided so as to overlap the click plate 23. The contact plate 24 has an inner peripheral portion 24a on the rotating shaft RA side and a peripheral portion 24b on the outer peripheral side thereof. The inner peripheral portion 24a has a size that substantially coincides with the inner peripheral portion 23a of the click plate 23, and the peripheral portion 24b has a protruding portion 24c that protrudes only to the abutting portion 23b where the screw 25 is not disposed. Yes. In other words, the contact plate 24 is formed so that the diameter in the vicinity of the fastening position of the screw 25 (distance from the rotation axis RA to the edge) is smaller than the diameter of the other position. In addition, the diameter of the fastening member vicinity of the fastening position should just be smaller than the diameter of at least one part position among other positions.

  The peripheral portion 24b is provided with a connecting portion 24d extending obliquely from the position overlapping the support portion 23e of the click plate 23 toward the inside of the housing. The connecting portion 24d is in contact with and electrically connected to a resistor 46 provided on the substrate 44 (see FIG. 2) in a circumferential shape. Then, the contact plate 24 is rotated and the connected resistor 46 is switched, whereby the operation of the dial device 3 is detected. In addition, although the connection part 24d is provided in the peripheral part 24b, it is possible to provide in the appropriate position of the contact board 24. FIG.

  The screw 25 penetrates through the screw holes 23h and 24h provided in the inner peripheral portion 23a of the click plate 23 and the inner peripheral portion 24a of the contact plate 24 from the back side of the upper surface portion 2a, and the housing of the shaft portion 21b of the dial member 21. The click plate 23 and the contact plate 24 are fixed to the dial member 21 by screwing into a screw hole 21 h provided on the surface on the inner side of the body. A plurality of screws 25 are arranged at a predetermined distance (a first predetermined diameter) in the radial direction from the rotation axis RA, and in the center of the slit portions 23c and 23c with respect to the circumferential direction, between the slit portions 23c and 23c. It is provided every other place. In addition, since the slit part 23f is provided in the outer peripheral side rather than the screw | thread 25 as mentioned above, it is provided in the position of the 2nd predetermined diameter larger than a 1st predetermined diameter. A surface of the shaft portion 21b on the inner side of the housing is provided with a protrusion 21d that protrudes in an annular shape around the shaft center, and a protrusion 21e that protrudes on the outer peripheral side from the protrusion 21d, and the protrusions 21d and 21e. Are fitted into holes 23i, 23j, 24i, 24j provided in the click plate 23 and the contact plate 24, whereby the click plate 23 and the contact plate 24 are positioned.

  According to the first embodiment, since the slit portion 23f is provided in the vicinity of the screw 25, the rigidity of the click plate 23 in the vicinity of the screw 25 is lowered, and the urging force is weakened. For this reason, the click feeling in the vicinity of the screw is weakened, and variations in the click feeling are alleviated.

  Since the slit portion 23f is provided on the outer peripheral side from the screw 25, the rigidity with the screw 25 as a fulcrum and the contact portion 23d as a power point is directly reduced.

  Since the slit part 23f is provided so as to be continuous with the slit part 23c and extend in the circumferential direction of the click plate 23, the contact part 23d provided with the slit part 23f is connected to the inner peripheral part 23a. The width is reduced, and not only the bending rigidity in the radial direction but also the torsional rigidity with respect to the inner peripheral portion 23a is reduced. Therefore, it is possible to effectively reduce the click feeling.

  Since the contact plate 24 is provided so as to overlap the click plate 23 and the diameter of the fastening position of the screw 25 is made smaller than the diameter of the non-fastening position, the urging force at the non-fastening position of the screw 25 of the click plate 23 increases. The click feeling at the 25 non-fastening positions is strengthened, and the variation in click feeling is alleviated. Note that superimposing the reinforcing leaf spring on the engaging leaf spring can be regarded as a concept of increasing the rigidity of the engaging leaf spring.

  Since the contact plate 24 is also used as a reinforcing leaf spring and a connection portion, the number of members is reduced, and the dial device is miniaturized.

(Second Embodiment)
In the second embodiment, the configuration other than the click plate, for example, the housing 2, the dial member 21, the steel ball 22, the contact plate 24, and the screw 25 are the same as those in the first embodiment. Only the differences from the first embodiment will be described below.

  FIG. 7A and FIG. 7B are conceptual diagrams showing a click plate 61 of the third embodiment. The elements corresponding to the opening portions for receiving the support portions 23e of the click plate 23 and the protrusions 21d and 21e are omitted.

  The click plate 61 is different from the first embodiment in that the peripheral edge 61b has a hole 61c as an engaging portion, and the shape and position of the slit portion 61f as a relaxing portion is the first. It is different from the embodiment. The hole 61 c penetrates the click plate 61. A plurality of holes 61c are arranged on the circumference (position of the third predetermined diameter) around the rotation axis RA. The slit portion 61f has an arcuate shape centered on the rotation axis RA, and is located on the outer peripheral side (the first predetermined diameter position) larger than the position where the screw 25 is provided (the first predetermined diameter position). At a predetermined diameter). Further, the slit portion 61f is provided at a position on the inner peripheral side with respect to the hole portion 61c and at the same position as the screw 25 in the circumferential direction.

A plurality of the recesses 71c are arranged on the circumference (position of the third predetermined diameter) around the rotation axis RA. The shape of the recess 71c may be set as appropriate, but may be formed in a dome shape for fitting with the steel ball 22, for example.

  According to the fourth embodiment, the recess 71c functions as an engaging portion, and the same effect as in the first embodiment can be obtained.

(Fifth embodiment)
In the fifth embodiment, the steel ball 22 rotates integrally with the dial member 81, and the click plate 82 and the reinforcing plate 83 as a reinforcing leaf spring are fixed to the upper surface portion 2a. This is different from the first embodiment.

  FIG. 9 is a cross-sectional view showing an example of the fifth embodiment. The click plate 82 is fixed to the upper surface portion 2a by screws 25 inserted from above. The dial member 81 has an operation portion 81a and a shaft portion 81b. The shaft portion 81b is inserted into the opening of the click plate 23 and the upper surface portion 2a so as to be rotatable with respect to the click plate 82 and the upper surface portion 2a. It is done. A spherical body holding portion 81g for holding the steel ball 22 is provided on the lower surface of the operation portion 81a. The steel ball 22 abuts on the click plate 82 and is urged upward by the click plate 82.

This is the same as the embodiment. Therefore, by rotating the dial member 81 with respect to the upper surface portion 2a, the steel balls 22 are sequentially engaged with the engaging portions.

  In the other embodiment, the insertion direction of the screw 25 and the direction in which the click plate urges the steel ball are the same direction. However, in the fifth embodiment, the insertion direction of the screw 25 is the urging direction of the click plate 82. And vice versa. Even in this case, when the peripheral edge 82b of the click plate 82 is pressed downward by the steel ball 22, the screw 25 prevents the inner peripheral side 82a from being lifted upward. At the position, the click feeling is stronger than the position away from the screw 25. Then, a relief portion is provided in the vicinity of the screw 25 or a reinforcing plate 82 that increases the urging force at the non-fastened position of the screw 25 is provided, so that the difference in the click feeling is alleviated.

The arrangement positions of the respective elements are set appropriately. It's okay. For example, the steel ball 22 and the click plate 82 may be provided below the upper surface portion 2a, or the urging direction of the click plate 82 and the insertion direction of the screw 25 may be configured in the same direction.

(Sixth embodiment)
In the sixth embodiment, configurations other than the contact plate, for example, the housing 2, the dial member 21, the steel ball 22, the click plate 23, and the screw 25 are the same as those in the first embodiment. Only the differences from the first embodiment will be described below.

  FIG. 10A and FIG. 7B are conceptual diagrams showing a click plate 23 and a reinforcing plate 91 as a reinforcing leaf spring of the sixth embodiment. The elements corresponding to the slit portion 23f and the support portion 23e of the click plate 23 are not shown.

  The sixth embodiment is different from the first embodiment in that a reinforcing plate 91 is provided. The reinforcing plate 91 is provided across the inner peripheral portion 23a and the peripheral portion 23b only at a position where the screw 25 is not fastened in the circumferential direction. That is, the reinforcing plate 91 is provided so as not to overlap in the vicinity of the fastening position of the screw 25. The reinforcing plate 91 is fixed to the click plate 23 by, for example, a double-sided tape.

  According to the sixth embodiment, the rigidity at the non-fastening position of the screw 25 of the click plate 23 is increased by the reinforcing plate 91, and the same effect as in the first embodiment can be obtained.

(Seventh embodiment)
In the seventh embodiment, the configuration other than the click plate, for example, the housing 2, the dial member 21, the steel ball 22, the contact plate 24, and the screw 25 are the same as those in the first embodiment. Only the differences from the first embodiment will be described below.

  Fig.11 (a) and FIG.11 (b) are the conceptual diagrams which show the click board 101 of 7th Embodiment. The elements corresponding to the opening portions for receiving the support portions 23e of the click plate 23 and the protrusions 21d and 21e are omitted.

  The seventh embodiment is different from the first embodiment in that the click plate 101 is thin in the vicinity of the screw 25 and thick in a position away from the screw 25. The range for reducing the plate thickness can be set as appropriate. For example, as shown by the dotted line L1, the click plate 101 is divided in the circumferential direction by the slit portion 101c as the engaging portion, and the thickness of the area S1 where the screw 25 is provided is not provided with the screw 25. It may be thinner than the plate thickness of the area S2.

  According to the seventh embodiment, since the plate thickness in the vicinity of the screw 25 is thinner than the position away from the screw 25, the rigidity in the vicinity of the screw 25 of the click plate 23 is lower than the position where the click 25 is desired to be separated. For this reason, the click feeling in the vicinity of the screw 25 is weakened, and variations in the click feeling are alleviated.

  In FIG. 11B, the thickness of the click plate 101 is increased toward the back side of the surface in contact with the steel ball 22, but the thickness may be increased toward the steel ball 22 side. In this case, since the amount of the click plate 101 pushed up by the steel ball 22 increases, the click feeling at a position away from the screw 25 becomes stronger.

(Eighth embodiment)
In the eighth embodiment, configurations other than the click plate, for example, the housing 2, the dial member 21, the steel ball 22, the contact plate 24, and the screw 25 are the same as those in the first embodiment. Only the differences from the first embodiment will be described below.

  FIG. 12A and FIG. 12B are conceptual diagrams showing a click plate 111 according to the eighth embodiment. The elements corresponding to the opening portions for receiving the support portions 23e of the click plate 23 and the protrusions 21d and 21e are omitted.

  The eighth embodiment is different from the first embodiment in that a groove 111h (so-called half blank) is formed in a concave shape on one surface side of the click plate 111 and in a convex shape on the other surface side. Is different. The groove 111h is formed so as to extend in the radial direction of the click plate 111 over the inner peripheral portion 111a and the peripheral portion 111b only at a position where the screw 25 is not fastened in the circumferential direction.

  According to the eighth embodiment, the wall portion 111i of the groove portion 111h increases the second moment of section of the cross section perpendicular to the groove portion 111h, and the bending rigidity increases. Variation in feeling is alleviated.

Therefore, it may be directly fixed to the rotating support or the rotating body, or may be indirectly fixed via another member.

  The engagement leaf spring is not limited to a substantially circular shape as long as it can bias the engaged body during rotation. For example, a fan shape may be sufficient and an outline may be uneven. Further, it may be flat or curved.

  Various methods for adjusting the biasing force of the engagement leaf spring, such as installation of the relaxation portion, installation of the reinforcing leaf spring, increase / decrease of the plate thickness of the engagement leaf spring, installation of the groove portion, etc. are appropriately selected and combined It's okay. For example, only one of them may be selected and implemented, or all may be combined. Moreover, you may set suitably the combination of the various methods for adjusting the urging | biasing force of the said leaf | plate spring, and each form of engagement parts, such as an engagement slit part and an engagement recessed part.

  The arrangement of the engaging portion and the fixing member may be set as appropriate. The present invention can be applied to any arrangement of rotating devices in which the click feeling of the engaging portion near the fixing member is stronger than the click feeling of the engaging portion away from the fixing member. For example, the present invention can also be applied to those in which the engaging portions are not evenly arranged with respect to the circumferential direction of the engaging leaf springs, and those in which the fixing members are not regularly arranged with respect to the arrangement of the engaging portions. is there.
