FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to refer to the same components, and duplicated descriptions will be omitted. (First embodiment) 1 is a perspective view of a digital camera (hereinafter, referred to as camera) 100, which is an example of an electronic device of this embodiment, viewed from above on the rear side (photographer side). Note that, although a digital camera will be described as the electronic device in this embodiment, a video camera or a mobile information terminal may also be used.

[0010] The exterior members of camera 100 are composed of top cover 101, front cover 102, and rear cover 103. A lens unit 104 is provided on the front side (subject side) of camera 100. A display unit 105 such as an LCD is supported on the rear side of camera 100 so as to be rotatable relative to camera 100. In addition, a shutter button 106 and a rotary operation unit 107 are provided on the top surface of camera 100 as operation members. Rotary operation unit 107 is an electronic dial device (operation device) for selecting the operation mode and various settings.

[0011] FIG. 2 is an exploded perspective view of the rotary operation unit 107 of this embodiment. The rotary operation unit 107 has a dial 1, an upper cover 101, a rotary member 5, a reflective member (detected member) 50, a distance measuring sensor (first detection member) 9, and a click mechanism 10. The dial 1 is used when a user performs a rotary operation. The upper cover 101 holds the dial 1 rotatably. The rotary member 5 and the reflective member 50 are fastened to the dial 1 by a fastening member 8 and rotate integrally with the dial 1. When fastening using the fastening member 8, it is necessary to consider the positional relationship between the reflective member 50 and the distance measuring sensor 9, and the color or paint for reducing reflection. The rotary member 5 and the reflective member 50 are formed by cutting or molding using resin or metal (for example, POM, ABS, SUS, iron), etc. For example, when the rotary member 5 is made of metal, the position is determined by fitting a pin or hole of the reflective member 50 to a positioning hole or pin (not shown) provided in the rotary member 5, and the reflective member 50 is fixed by heat caulking, adhesion, or the like. When the rotating member 5 is resin molded, the shape of the reflecting member 50 may be molded integrally with the rotating member 5. In this embodiment, the rotating member 5 and the reflecting member 50 are fastened to the dial 1 by a fastening member 8, but they may be fastened by thermal welding or the like. The distance measuring sensor 9 can detect the distance to the reflecting member 50 in a non-contact manner. The click mechanism 10 generates an operating force (click force) that gives a clicking sensation in response to a rotation operation of the dial 1. In this embodiment, the rotary operation unit 107 selects various shooting modes that set shooting conditions, such as a shutter speed priority mode (Tv mode) or an aperture value priority mode (Av mode), in response to a clockwise or counterclockwise rotation operation of the dial 1.

[0012] As shown in FIG. 2(c), the outer circumference of the rotating member 5 is formed with a wavy uneven portion having alternating valley portions 5c with small radii and peak portions 5d with large radii at regular intervals. The click mechanism 10 includes a compression spring 6 and a click ball (ball member) 7. The compression spring 6 is engaged with a spring receiving portion 101e of the top cover 101. The click ball 7 is biased by the compression spring 6 toward the rotation center of the dial 1 against the unevenness of the uneven portion. As a result, the dial 1 stops at a position where the click ball 7 fits into the valley portions 5c.

[0013] When the user rotates the dial 1 by one position, the click ball 7 climbs over the peak 5d of the rotating member 5 and fits into the adjacent valley 5c. At this time, an operating force is generated in the dial 1, and the user feels a clicking sensation equivalent to one click. This clicking sensation enables the user to rotate the dial 1 accurately the number of clicks intended.

[0014] 2(b), the reflecting member 50 is provided with a plurality of stepped portions (reflective surfaces) that are displaced in the rotation axis direction of the dial 1 (each having a different position (height) in the rotation axis direction). The distance measuring sensor 9 is mounted on an FPC (flexible printed circuit) so as to face the plurality of stepped portions. In this embodiment, the number of stepped portions of the reflecting member 50 corresponds to the number of positions of the dial 1.

[0015] In this embodiment, the distance measuring sensor 9 is a so-called photoreflector that includes a light projecting section 9a and a light receiving section 9b. In this embodiment, the light projecting section 9a and the light receiving section 9b are arranged so that a line connecting their optical centers coincides with the rotation center of the dial 1. This allows the timing at which the step section of the reflective member 50 passes through the light projecting section 9a to coincide with the timing at which it passes through the light receiving section 9b, thereby suppressing deviation in detection timing.

[0016] In this embodiment, the dial 1 has eight positions (rotation angle ranges) displayed as P1 to P8 as shown in FIG. 2(d). A user can freely switch between eight shooting modes by rotating the dial 1. The mode name on the dial 1 is aligned with the index 108 on the exterior cover 101 shown in FIG. 1 to clearly show the user which shooting mode is selected. The number of positions on the dial 1 can be changed according to the specifications of the rotary operation unit 107. For example, it can be changed to 4, 12, 13, etc., regardless of whether it is an odd number or an even number.

[0017] The distance measuring sensor 9 detects the distance to the step by reading the value when the light projected by the light projecting unit 9a is reflected by the step and enters the light receiving unit 9b, that is, the value of the light receiving rate. Note that in this embodiment, a photoreflector that uses light emitted from an infrared LED is used as the distance measuring sensor 9, but the present invention is not limited to this as long as it is possible to detect the distance to the step.

[0018] When the user selects a predetermined position of the dial 1 (when the click ball 7 fits into the valley portion 5c of the rotating member 5), the distance measuring sensor 9 is disposed so as to be located at the center of the circumferential width of one of the steps. Note that in this embodiment, the distance measuring sensor 9 is disposed at the same position in the circumferential direction as the click ball 7 fits into the valley portion 5c, but the distance measuring sensor 9 may be disposed anywhere in the circumferential direction depending on the layout of the surrounding members.

[0019] Hereinafter, the relationship between the shape of the step portion of the reflecting member 50 and the detection of the rotational position of the rotary operation unit 107 for one rotational revolution will be described.

[0020] Fig. 3(a) is a development view showing an example of the height of the step portion of the reflecting member 50. Fig. 3(b) is a sensor light-receiving efficiency diagram of the rotary operation unit 107 for one rotation of rotation operation corresponding to the shape of the step portion of Fig. 3(a). Fig. 3(c) is a development view showing another example of the height of the step portion of the reflecting member 50. Fig. 3(d) is a sensor light-receiving efficiency diagram of the rotary operation unit 107 for one rotation of rotation operation corresponding to the shape of the step portion of Fig. 3(c).

[0021] In this embodiment, as described above, the dial 1 has eight positions. The reflecting member 50 is provided with eight steps corresponding to the number of positions of the dial 1. The angular range of one step in the circumferential direction is 45 degrees. The eight steps are provided such that the distances to the distance measuring sensor 9 are different from each other in the direction of the rotation axis of the dial 1. In other words, the light receiving rate detected by the distance measuring sensor 9 is different for each step. This makes it possible to determine the rotation position of the dial 1 according to the light receiving rate of the distance measuring sensor 9, which is correlated with the rotation position of the dial 1.

[0022] Here, the eight step portions are defined as 50a to 50h in order from the one closest to the distance measuring sensor 9. Also, the distances from the distance measuring sensor 9 to the step portions 50a to 50h are defined as D1 to D8, respectively.

[0023] In FIG. 3(a), the step portions are provided so that the distance measuring sensor 9 faces the step portions of the step portion ... Dials 1 with stoppers are often used for dials 1 with a small number of positions, and they make it easy to rotate to the stop position without visually checking the position during rotation. For this reason, dials 1 with stoppers are often preferred when there is a vertical relationship between the settings that can be changed depending on the rotation position of the dial 1.

[0024] 3(c), the eight step portions are defined as 50a to 50h in order from the one closest to the distance measuring sensor 9. The distances from the distance measuring sensor 9 to the step portions 50a to 50h are defined as D1 to D8, respectively.

[0025] In FIG. 3(c), the distance measuring sensor 9 faces the step portion that is gradually farther away in response to the rotation operation from the state where it faces the closest step portion (first surface) 50a, and faces the step portion that is the farthest in half a rotation operation (final surface) 50h. The distance measuring sensor 9 also faces the step portion that is gradually closer in response to the rotation operation, and faces the step portion 50a in half a rotation operation. The step portions are provided so that the distance measuring sensor 9 faces the step portions in the above-mentioned order. Also, as shown in FIG. 3(c), from the state where the distance measuring sensor 9 faces the step portion 50a to the state where it faces the step portion 50h, the height of the facing step portion differs depending on the rotation direction (circumferential direction). Specifically, the height of the facing step portion in the rotation operation in the clockwise direction (first rotation direction) differs from the height of the facing step portion in the rotation operation in the counterclockwise direction (second rotation direction opposite to the first rotation direction) in the rotation axis direction. By providing the stepped portions in this way, the distance measuring sensor 9 can obtain a unique light receiving rate that differs for each stepped portion. Since there is no large change in the light receiving rate throughout the entire rotation range, when using a dial 1 that can be rotated 360 degrees and does not have a stopper, it is preferable to form the stepped portion in the shape shown in Fig. 3(c).

[0026] 4 is a diagram showing the relationship between the reflection gain (light receiving rate) and the distance to the reflecting member 50 when a dial is detected using the distance measuring sensor 9 and the reflecting member 50. In general, the light beam projected from the distance measuring sensor 9 spreads in a cone shape, so the relationship between the distance to the reflecting member 50 and the reflection gain is nonlinear. As shown in FIG. 4, the longer the distance to the reflecting member 50, the smaller the change in the reflection gain. In order to change the reflection gain at equal intervals, the longer the distance from the reflecting member 50, the wider the interval at which the distance from the reflecting member 50 changes.

[0027] In this embodiment, as shown in Figures 3(a) and 3(c), the step at the time of switching is set to be larger as the step portion is farther away from the distance measuring sensor 9. Specifically, the step portion is set so as to satisfy the following conditional expression (1).

[0028] D n+2 -D n+1 >D n+1 -Dn (n: natural number) (1) For example, a case will be described in which the multiple step portions include three step portions (first to third surfaces) provided consecutively in the rotational axis direction from the distance measurement sensor 9 side. In this case, the distance in the rotational axis direction between the first step portion and the second step portion from the distance measurement sensor 9 side is shorter than the distance in the rotational axis direction between the second step portion and the third step portion from the distance measurement sensor 9 side.

[0029] In this embodiment, since the non-contact distance measuring sensor 9 is used to detect the distance to the reflective member 50, durability can be improved compared to a configuration using a phase contact and a conductive pattern, and it is possible to suppress the occurrence of defects such as erroneous detection and short circuits due to wear on the conductive pattern, etc. In addition, since a mechanism for converting the rotational movement of the dial 1 into linear movement is not used, it is possible to suppress an increase in size of the rotary operation unit 107. Second embodiment In the first embodiment, it is possible to create as many modes of the rotation operation unit 107 as there are step portions of the reflecting member 50. In other words, in order to increase the number of modes, it is necessary to increase the number of step portions, and as the number of modes increases, the size of the rotation operation unit 107 in the direction of the rotation axis increases.

[0030] Furthermore, when the user rotates the dial 1 at a low speed, the time it takes to pass the step increases, and there is a possibility that the output of the distance measuring sensor 9 may vary when passing over the step (for example, when transitioning from step 50g to step 50h in FIG. 3). The dial 1 is stable with the click ball 7 fitted into the valley 5c of the rotating member 5, so the occurrence of false detection can be suppressed by waiting for the output to stabilize, but the immediacy of the switching timing is lost.

[0031] In this embodiment, the configuration of a rotary operation unit equipped with a dial that has many modes and high immediacy will be described. The basic configuration of a camera, which is an example of an electronic device of this embodiment, is similar to the camera 100 of the first embodiment. In this embodiment, only the configuration different from the first embodiment will be described, the same reference numbers will be used for the same members, and duplicated descriptions will be omitted.

[0032] 5 is an exploded perspective view of the rotary operation unit 107 of this embodiment. The rotary operation unit 107 has a dial 1, an upper cover 101, a rotary member 5, a reflecting member 50, a distance measuring sensor 9, a proximity sensor (second detection unit) 99, and a click mechanism 10.

[0033] In this embodiment, the dial 1 has 12 positions (rotation angle ranges) displayed as P1 to P12, as shown in Fig. 5(d). A user can freely switch between 12 different shooting modes by rotating the dial 1.

[0034] The reflective member 50 has a concentric structure of an inner reflective portion 501 and an outer reflective portion 502 in the rotation axis direction. The distance measuring sensor 9 and the proximity sensor 99 are mounted on the FPC so as to face the outer reflective portion 502 and the inner reflective portion 501, respectively. In this embodiment, the distance measuring sensor 9 and the proximity sensor 99 are disposed on the same plane of the FPC.

[0035] In this embodiment, the proximity sensor 99 is a so-called photoreflector that includes a light-projecting portion 99a and a light-receiving portion 99b. In this embodiment, as shown in Fig. 5(c), the light-projecting portions 9a, 99a and the light-receiving portions 9b, 99b are arranged so that a line connecting their optical centers coincides with the rotation center of the dial 1. This makes it possible to suppress deviations in detection timing due to the direction of rotation.

[0036] The proximity sensor 99 detects brightness (ON / OFF) by reading the value when the light projected by the light projecting unit 99a is reflected by the reflecting member 50 and enters the light receiving unit 99b, i.e., the value of the light receiving rate. Specifically, the proximity sensor 99 detects in a non-contact manner whether the amount of light reflected from the reflecting member 50 is greater than a predetermined value. Note that, although a photoreflector that uses light emitted from an infrared LED is used as the proximity sensor 99 in this embodiment, the present invention is not limited to this as long as it is capable of detecting brightness (ON / OFF).

[0037] 5(c), it is preferable that the distance measuring sensor 9 and the proximity sensor 99 are disposed 180 degrees apart from each other across the rotation axis, which can reduce the risk of crosstalk, in which the light from each light projector is mixed and received.

[0038] The inner reflective portion 501 is divided into bright portions 501a, which are surfaces with high reflectivity, and dark portions 501b, which are surfaces with low reflectivity, in the same number as the number of positions of the dial 1. In this embodiment, the number of positions of the dial 1 is 12, and six bright portions 501a and six dark portions 501b are provided. In response to a rotation operation of the dial 1, the proximity sensor 99 faces one of the bright portions 501a and the dark portions 501b. Here, the bright portions 501a and the dark portions 501b only need to have a difference in reflectivity that allows the proximity sensor 99 to detect light and dark (ON / OFF), and various options are possible for the material, color, and surface condition. In this embodiment, the bright portions 501a are formed of a highly reflective white, glossy resin material, and the dark portions 501b are formed by partially applying black printing with a low glossiness.

[0039] The outer circumferential reflecting portion 502 is provided with a plurality of stepped portions (each having a different position (height) in the rotation axis direction) that are displaced in the rotation axis direction of the dial 1. In this embodiment, in consideration of workability, the position of the surface 502a closest to the distance measuring sensor 9 in the rotation axis direction of the dial 1 is set to be the same as the position of the inner circumferential reflecting portion 501.

[0040] FIG. 6 is a development view showing an example of the relationship between the brightness and darkness of the inner reflective portion 501 and the height of the step portion of the outer reflective portion 502. In the rotary operation unit 107 of FIG. 6, the number of selectable modes is 12. As shown in FIG. 6, in the inner reflective portion 501, the bright portion 501a and the dark portion 501b are repeatedly provided at every 30 degrees of rotation angle. The outer reflective portion 502 has step portions of different heights having different distances (different heights) from the distance measuring sensor 9. Here, the step portions are defined as 502a to 502f from the one closest to the distance measuring sensor 9. In addition, the distances from the distance measuring sensor 9 to the step portions 502a to 502f are defined as D1 to D6, respectively. In this embodiment, the number of heights of the step portions of the outer reflective portion 502 is half the number of modes, and when a dial 1 with 12 positions is used, the number of heights is 6.

[0041] In this embodiment, the brightness that changes every 30 degrees of rotation angle in the inner reflective portion 501 and the six heights of the steps in the outer reflective portion 502 are used in combination. That is, by combining the six levels of light receiving rate detected by the distance measuring sensor 9 with the output (brightness) of the proximity sensor 99, the distance measuring sensor 9 can detect 12 (=6×2) different states. This makes it possible to determine 12 position positions.

[0042] In this manner, in this embodiment, the number of stepped portions can be reduced to half the number of modes, so that the size of the rotary operation unit 107 can be prevented from increasing.

[0043] The timing for checking the output (light receiving rate) of the distance measuring sensor 9 is limited to the timing when the power is turned on (power is turned on) and the timing when the output (light / dark) of the proximity sensor 99 changes. This allows the distance measuring sensor 9 to check the output after the outer circumferential reflector 502 passes a step, enabling highly immediate detection without false detection. Also, by using a change in the output of the proximity sensor 99 as a trigger to energize the distance measuring sensor 9, it becomes unnecessary to energize it constantly, making it possible to reduce power consumption.

[0044] As described above with reference to Fig. 4, in order to change the reflection gain at equal intervals, it is necessary to widen the interval at which the distance from the reflecting member 50 changes as the distance from the reflecting member 50 increases. In this embodiment, as shown in Fig. 6, the step portions are set to satisfy the above-mentioned conditional formula (1) so that the step at the time of switching becomes larger as the step portion is farther away from the distance measuring sensor 9.

[0045] Fig. 7 is a development view showing another example of the relationship between the brightness of the inner reflective portion 501 and the height of the steps of the outer reflective portion 502. In the rotary operation unit 107 of Fig. 7, the number of selectable modes is 11. As shown in Fig. 7, the inner reflective portion 501 has light portions 501a and dark portions 501b provided repeatedly. The outer reflective portion 502 has steps 502a to 502f that are at different distances (different heights) from the distance measuring sensor 9.

[0046] 6, first, the rotation angle range (circumferential angle) of the dial 1 in one position is about 33 degrees (360 / 11 degrees). Next, within the rotation angle range corresponding to the step 502a closest to the distance measuring sensor 9, the light portion 501a and the dark portion 501b switch once. Therefore, within that rotation angle range, the output of the proximity sensor 99 changes once, but only within that rotation angle range, even if the output value of the proximity sensor 99 changes, it is set to determine that the position is the same. In other words, for the output (light receiving rate) corresponding to the step 502a obtained by the distance measuring sensor 9, both combinations of light and dark outputs obtained by the proximity sensor 99 are determined to be the same position.

[0047] With the above settings, the combination of distance measuring sensor 9 and proximity sensor 99 makes it possible to detect 11 different states and determine 11 position locations.

[0048] 7, the rotation angle range corresponding to the bright portion 501a and the dark portion 501b is set so that the timing of switching between the bright portion 501a and the dark portion 501b is not in the center of the rotation angle range corresponding to the step portion 502a. As a result, in a state where the user selects a predetermined position of the dial 1 (a state where the click ball 7 is fitted in the valley portion 5c of the rotating member 5), the proximity sensor 99 is disposed in the center (intermediate rotation position) of the rotation angle range corresponding to the step portion 502a. Therefore, it is possible to obtain reflection from the bright portion 501a. In other words, when the position of the dial 1 is stable, no change occurs in the output (brightness) of the proximity sensor 99.

[0049] As described above, when the distance measuring sensor 9 is energized using a change in output from the proximity sensor 99 as a trigger, power consumption can be reduced in the same way as with the dial 1 having an even number of positions.

[0050] In this embodiment, a light / dark transition section is provided within the rotation angle range corresponding to the step section 502a closest to the distance measurement sensor 9. However, as mentioned above, this takes into consideration that the change in reflection gain decreases as the distance to the reflective member 50 increases.

[0051] As described above, with the configuration of this embodiment, it is possible to realize a small rotary operating member that is highly durable and reduces false detections through a non-contact method, without causing problems such as large size and reduced immediacy, even in dials with a large number of modes.

[0052] The radial positional relationship between the inner peripheral reflecting portion 501 and the outer peripheral reflecting portion 502 and the sensors facing each other may be reversed.
