Description

  The present invention relates to an electronic dial device mounted on an electronic device such as a digital camera.

  2. Description of the Related Art Conventionally, electronic devices such as digital cameras, video cameras, and portable information terminals are provided with an electronic dial device for setting operation modes and various settings. In the electronic dial device, a substrate provided with a conductive pattern is fixed to the device main body, and a leaf spring-like phase contact piece sliding on the conductive pattern is fixed to the dial according to the rotation of the dial. ing. Also, it has a plurality of click grooves arranged side by side in the rotational direction and a sphere engaged with these click grooves, and by engaging and disengaging this sphere and the plurality of click grooves according to the rotation of the dial The dial rotation operation is designed to generate a click feeling.

  Such a dial device determines the position (position) of the dial by detecting the conduction state of the conductive pattern and the phase contact piece. Further, the electronic dial device may reduce the number of electrical signals with respect to the number of positions by using a gray code. The gray code switches from "active" to "inactive" or "inactive" to "active" in order to prevent an erroneous output when moving to an adjacent position. Code arrangement is assumed. However, in the case where the number of positions is an odd number, the above-described premise does not hold between some of the positions, and erroneous output may occur when moving to an adjacent position.

  For example, Patent Document 1 discloses a rotary switch that can reliably solve the problem of erroneous output between positions when switching switches in a cord output type rotary switch. By providing a determination signal terminal for outputting a determination signal, erroneous output can be suppressed.

  Also, by providing a conductive pattern having two code arrays between one of n (odd), it is possible to suppress erroneous output with n (odd) position number and n + 1 code number. It is known.

Unexamined-Japanese-Patent No. 2006-250566

  However, in the rotary switch disclosed in Patent Document 1, since the determination signal is disposed on the sliding portion with a certain distance or more, there is a possibility that the conductive pattern may peel off due to the sliding wear. In order to avoid peeling of the conductive pattern, an insulating sheet may be disposed at the end of the conductive pattern, but in that case, the dial operation feeling due to the step of the insulating sheet may be reduced. In addition, since a phase occurs in which the determined signal does not touch the phase contact piece, the phase contact piece temporarily becomes an electrically floating metal, and the signal may not be stable and may shake.

  On the other hand, in the above-mentioned prior art, there is a place where the cord switches between one position, and a place where there is no conductive pattern, ie, a groove, is formed on the substrate. Since the groove is not in the center of the two positions where the click load is high but in one position where the click load is low, the user is likely to feel a step during the rotation operation, and there is a concern that the operation feeling may be reduced.

  Therefore, an object of the present invention is to provide an electronic dial device and an electronic device capable of generating a stable signal without sacrificing operation feeling.

  An electronic dial device according to one aspect of the present invention includes a rotation operation member, a conductive member that rotates with the rotation operation member, and a plurality of conductive regions insulated from each other, and the rotation operation member rotates according to the rotation. And a mode setting unit capable of setting a plurality of modes in accordance with a setting position of the rotary operation member, and a conductive pattern with which the conductive member slidably contacts, and a part of the periphery of the rotary operation member And a wall.

  An electronic device according to another aspect of the present invention includes the electronic dial device.

  Other objects and features of the present invention will be described in the following embodiments.

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

  First, with reference to FIG. 1, an outline of an imaging device according to the present embodiment will be described. FIG. 1 is a perspective view of an imaging device (digital single-lens reflex camera) 1. A mode dial (rotation operation member) 2 for setting various photographing conditions in photographing is disposed on the upper surface of the imaging device 1. A shooting mode in which shooting conditions such as shutter speed priority mode (Tv mode) and aperture value priority mode (Av mode) are set by rotating the mode dial 2 clockwise or counterclockwise according to the user's rotation operation. (Mode) can be selected (set). Reference numeral 3 denotes an exterior cover provided on the upper surface side of the imaging device 1. In the present embodiment, an interchangeable lens (imaging optical system) (not shown) can be detachably attached to the imaging device 1. However, the present embodiment is not limited to this, and is also applicable to an imaging apparatus in which an imaging optical system and an imaging apparatus main body are integrally configured.

  Next, the configuration of the electronic dial device including the mode dial 2 will be described with reference to FIG. FIG. 2 is an exploded perspective view of the electronic dial device 100. In FIG. 2, 4 is a flexible substrate (FPC, substrate), and 5 is a conductive pattern provided on the flexible substrate 4. 6 is a phase contact piece (conductive member) which rotates with the mode dial 2, and 7 is a click plate. The phase contact piece 6 is integrated with the click plate 7 by heat caulking. The click plate 7 has valleys of the same number as the rotational phase of the mode dial 2, and when the click ball 8 engages with the valleys, a click feeling is generated when the mode dial 2 is rotated. The coil spring 9 has a role of urging the click ball 8 against the click plate 7.

  The mode dial cap 10 is adhesively fixed to the mode dial 2, and the same number of patterns as the rotational phase (number of states) of the mode dial 2 are printed. By combining the pattern of the mode dial cap 10 and the index 11 of the exterior cover 3, it is clearly indicated to the user which imaging mode is selected (set). The power lever 12 is a member for turning on / off the power of the imaging device 1. The power supply lever 12 is provided with an operation unit 14 for the user to perform an ON / OFF operation of the power supply pinched with a finger. The leaf spring 13 engages with the valley portion of the inner wall surface of the power supply lever 12 and generates a click feeling at the time of power ON / OFF operation. The storage means (memory) 16 stores a code arrangement list (code table) shown in FIG. 6 described later. The mode setting means (control unit) 15 sets a plurality of modes (FIG. 6) according to the set position (positions P1 to P9 shown in FIG. 6) of the mode dial 2 based on the code table stored in the storage means 16. It is possible to selectively set the modes A to I) shown.

  Next, with reference to FIG. 3, the relationship between the rotational position of the electronic dial device 100 and the mode (shooting mode) will be described. FIG. 3 is a top view of the electronic dial device 100. As shown in FIG. 3, in the present embodiment, the mode dial cap 10 has a total of modes “A”, “B”, “C”, “D”, “E”, “F”, “G”, “H”, and “I”. Nine types of modes are shown corresponding to the positions (setting positions) P1 to P9 of the mode dial 2, respectively. In the present embodiment, positions P1 to P9 correspond to shooting modes of modes A to I, and are disposed at intervals of a rotational angle of 40 degrees.

  The user can freely switch nine types of shooting modes by rotating the mode dial 2. Further, in the present embodiment, the mode dial 2 is not provided with a rotation end point at which the mode dial 2 can not be operated at the time of the clockwise or counterclockwise operation. Thus, the user can keep rotating the mode dial 2 in both clockwise and counterclockwise rotation directions.

  Next, the configuration of the phase contact piece (conductive member) 6 in the present embodiment will be described with reference to FIG. FIG. 4 is a top view of the phase contact piece 6. As shown in FIG. 4, the phase contact piece 6 is made of a conductive material having an elastic shape, and at the tip of the phase contact piece 6, contacts 6 a, 6 b, 6 c with the conductive pattern 5 are made. 6d is provided. The respective distances from the rotation center of the mode dial 2 to the contacts 6a, 6b, 6c, 6d are all different from one another, and the rotation loci of the four contacts 6a to 6d are arranged so as not to overlap each other. The contacts 6a to 6d are electrically stably connected to the flexible substrate 4 by being pressed against the conductive pattern 5 of the flexible substrate 4 with a predetermined load. In addition, all the contacts 6a to 6d each have two split contacts. This is because even if one of the split contacts can not be conducted to the conductive pattern 5 due to foreign matter such as dust, the other split contact maintains the conductive state. A straight line L1 connecting the contact points 6a and 6c and a straight line L2 connecting the contact points 6b and 6d are set on straight lines passing through the rotation center 31 of the phase segment 6. The straight line L1 and the straight line L2 are set at mutually opposite positions with respect to the rotation center 31 of the phase segment 6, respectively. This suppresses the inclination of the phase contact piece 6 by balancing the contact pressure load with respect to the rotation center 31 of the phase segment 6 as much as possible, and suppresses the touch defect when the user rotates the mode dial 2. It is for.

  Next, with reference to FIG. 5, the flexible substrate 4 provided with the conductive pattern 5 will be described. FIG. 5 is a top view of the flexible substrate 4 provided with the conductive pattern 5. The conductive pattern 5 has five signal areas (a plurality of conductive areas) insulated from each other, and the phase contact piece 6 slidably contacts according to the rotation of the mode dial 2. One of five signal areas is an area of a reference potential signal (GND signal). The GND signal can be electrically connected to the remaining four signal areas (conductive regions) via the phase contact piece 6. In the present embodiment, each of four signal potentials (a plurality of signal levels) is switched to active or inactive according to the rotational phase (rotational position) of the mode dial 2 according to the position (position) of the phase contact piece 6 Can. Here, active means that the signal level is high level (H level), that is, "1" (first state), and inactive means that the signal level is low level (L level), that is, "0". It is a state (second state). Whether each of the four signal potentials is at H level or L level is detected by a detection unit (not shown). Then, the mode setting means 15 instructs switching to the mode selected by the user.

  In the case of the mode dial 2 having n modes, it is conceivable to dispose a conductive pattern 5 (a plurality of conductive regions) having a combination of n types of signal levels. However, in this case, the number of signals increases according to the number of modes n, and not only the mode dial 2 but also the entire product such as the imaging device 1 becomes large. For this reason, a gray code capable of reducing the number of signals is used by converting the mode number n into a combination of signal levels “0” (LOW) and “1” (HIGH), a so-called binary number. 1 in the binary number is replaced with the aforementioned signal potential HIGH, and 0 is replaced with the aforementioned signal potential LOW. Also, the gray code has a rule that only one signal level of a plurality of signals changes when shifting to an adjacent code. Hereinafter, in the description of the code (signal level), it is referred to as “H” (H level) if the potential of the signal is HIGH, and “L” (L level) if the potential of the signal is LOW. The code arrangement (combination of a plurality of signal levels) is described in the order of “signal 1, signal 2, signal 3, signal 4”.

  FIG. 9A, FIG. 9B, and FIG. 9C are plan views of a flexible substrate having a conductive pattern not conforming to the rule of the gray code as a comparative example. Since the contact 6d is connected to the conductive area of the GND signal (the conductive area for outputting the signal GND), the level of the signal regarding the remaining contact 6a, the contact 6b and the conductive area in contact with the contact 6c is L. In FIG. 9A, from the code “HLLL” (combination of a plurality of signal levels), the phase contact piece 6 is rotated about the rotation center 31 in the counterclockwise rotation direction 20 and the code “HLHH” It is a figure which is going to transfer to a conductive area. Specifically, the signal 4 in contact with the conductive area (fourth conductive area) in contact with the contact 6b from L to H in the conductive area (third conductive area) in contact with the contact 6a Two signals are going to change simultaneously from L to H.

  In FIG. 9B, when the shapes of the conductive pattern 5 and the phase contact piece 6 match the design values, and the center 30 of the conductive pattern 5 and the rotation center 31 of the phase contact piece 6 match each other, It is a figure of the moment when the phase contact piece 6 rotates in the rotation direction 20, and it transfers to the electrically conductive area | region of code | cord "HLHH." If the above conditions are satisfied, it is possible to simultaneously change the two signals "signal 3" and "signal 4" in a strict sense. However, in consideration of variations in part shape and assembly, the above-mentioned conditions are unlikely to be satisfied, and in most cases, the signals change one by one in order. There are the following two ways of change.

"HLLL"->"HLLH"->"HLHH" ... order (1)
"HLLL"->"HLHL"->"HLHH" ... order (2)
In FIG. 9C, the center 30 of the conductive pattern 5 and the rotation center 31 of the phase contact piece 6 are shifted from each other, and the transition from “HLLL” to “HLHH” occurs in the sequence (2). It is a figure of the moment passing through "HLHL". The "HLLH" of the order (1) and the "HLHL" of the order (2) are both unnecessary codes not intended at the time of mode setting.

  The Gray code must obey the rule that only one signal will change when transitioning to an adjacent code as described above. However, as in the dial described in the present embodiment, in the dial having an odd number of positions n (the number of modes) and no rotation end point, there are always places where the Gray code rule can not be observed.

  In the dial having no rotation end point, in addition to the movement between adjacent positions such as the position P1 to the position P2, the movement between the position P1 and the position P9 is added. Therefore, the codes disposed at the positions P1 and P9 also correspond to the codes adjacent to each other. For example, when changing one signal from H to L when moving to an adjacent signal with a dial with no rotation end point, keep turning in the same direction of rotation and keep changing to the same position without fail. The signal must change from L to H. That is, at least two changes of "H to L" and "L to H" are required, and since it is applied to all signals, the number of changes of the code must be an even number. When the position number n (the number of setting positions of the mode dial 2) corresponding to the mode number is an even number, the number of times of changing the code is (n-1) when rotating from the position P1 to the position Pn. When the mode dial 2 has no rotation end point, the code changes once between the position P1 and the position Pn. That is, the number of times the code changes is a total of n times. That is, it always has an even number of code changes, and it is possible to set a code arrangement that complies with the Gray code rules.

  On the other hand, when the number of positions n (the number of setting positions) corresponding to the number of modes is an odd number, the number of times the code changes from position P1 to position Pn is (n-1) times (even times). If the mode dial 2 does not have a rotation end point, one code change number between the position P1 and the position Pn is added, and the number of code changes is a total of n times (odd number times). That is, it always has an odd number of code changes, and there is always one place where the Gray code rule can not be observed.

  FIG. 10 is a gray code arrangement table as a comparative example when the number of positions is nine. As described above, since the number of positions (number of modes) is an odd number, the Gray code rule is not observed. It is assumed that the user rotates the mode dial to change from position P9 where mode I is set to position P1 where mode A is set. At that time, since two signals are hardly switched simultaneously, the signals change one by one in order. The order is twofold.

  FIG. 11 is a diagram showing the order of signal changes when the mode dial 2 is operated from the position P9 to the position P1 in the code arrangement shown in FIG. As shown in FIG. 11, an order (3) via mode D assigned to position P4 or an order (4) via mode H assigned to position P8 occurs. That is, when the user rotates mode dial 2 and changes the mode from mode A to mode I or mode I to mode A, the mode is being operated while the user rotates only one position. The mode may be changed to D or mode H. In particular, when the user performs the rotation operation slowly or is stopped during the rotation, it is easy to recognize a change to a mode not intended by the user. For this reason, it is not preferable that there is a place where the mode is switched to the mode not intended by the user during the rotation.

  Next, the configuration of the present embodiment for solving the problems specific to the mode dial having an odd number of positions will be described. The code arrangement | sequence table in this embodiment is demonstrated with reference to FIG. FIG. 6 is a code arrangement table in the present embodiment, showing the relationship between the position (position) of the code arrangement, the mode (shooting mode), and the codes. As shown in FIG. 6, ten codes are prepared by adding one to the number of modes as codes to be assigned to the mode dial 2 having nine positions and nine modes. At this time, the ten codes are in different arrangements (combinations of different signal levels). Also, only one signal changes when moving to an adjacent code between codes C1 to C10 (only one signal level of four signal areas (signals 1 to 4) changes) Let's say that the coding sequence. In addition, even when moving the code from the code C10 to the code C1, the code sequence that changes only one kind of signal is used.

  Here, the conductor patterns are created from the cord C1 to the cord C9, and no conductor pattern related to the cord C10 is created. Then, as in the conventional case, modes A to I are assigned to the codes C1 to C9, respectively. In this embodiment, in addition to that, the code C10 is assigned the same mode as the mode assigned to the code C1 or the code C9, that is, mode A or mode I. In FIG. 6, the same mode I as that of the code C9 is assigned to the code C10.

  Next, with reference to FIG. 7, the flexible substrate 4 having the conductive pattern 5 in the present embodiment will be described. FIG. 7 is a top view of the flexible substrate 4 having a conductive pattern in the present embodiment. FIG. 7A shows the phase contact piece 6 disposed at the position P9, and FIG. 7B shows the phase contact piece 6 disposed at the position P1. The operation in which the user rotates the mode dial 2 in the rotational direction 20 to change the position P9 to the position P1 is an operation to change two signal levels (signals 3 and 4 in the present embodiment). It does not follow.

  FIG. 8 is a diagram showing the sequence of signal changes when the mode dial 2 is operated from the position P9 to the position P1 in the code arrangement shown in FIG. As shown in FIG. 8, the order (5) of passing through the combination “HHLH” of the signal levels of the code C10 and the order (6) of passing through the combination “HHHL” of the signal levels of the code C6 occur. However, the combination "HHLH" of the signal levels of the code C10 is a sequence (combination) different from any of the codes C1 to C9. For this reason, during the operation of the mode dial 2, it does not switch to any of the modes assigned to the codes C1 to C9. The same mode as that of the adjacent code C9, that is, mode I is assigned to the combination "HHLH" of the signal levels of the code C10. Therefore, even if the signal level changes in order (5), the mode changes in the order of “I” → “I” → “A”. The change of “I” → “I” is equivalent to the fact that the imaging mode of the imaging device 1 is not changed. Therefore, the user can change the mode without noticing that the code C10 has been passed.

  On the other hand, in the case of order (6), the combination “HHHL” of the signal level of code C6 passes through the arrangement (combination) of code C6, so the mode changes in the order of “I” → “F” → “A” Do. Therefore, the user may notice switching to the mode F when the mode dial 2 is operated from the position P9 to the position P1, particularly slowly. Thus, when a signal that switches the mode from “I” to “F” or “A” to “F” is detected, the mode setting unit 15 performs control so as not to instruct to switch the mode to “F”. There is a need. However, in that case, if the user actually performs an operation to switch the mode from “I” to “F” or “A” to “F” quickly and continuously without passing through any other mode. May not switch to "F".

  Therefore, in the present embodiment, as shown in FIG. 12, a wall (a wall, a convex portion, a projection) 50 for preventing the continuous rotation operation of the mode dial 2 by the user is provided in a part of the periphery of the mode dial 2 . FIG. 12 is a top view of the electronic dial device 100 in the present embodiment.

  As shown in FIG. 12, it is a general rotation operation method for the user to pinch and rotate the mode dial 2 with two fingers 40 and 41. However, by providing the wall 50 in the vicinity of the mode dial 2, one of the finger 40 and the finger 41 hits the wall 50, making it difficult for the user to continuously rotate the mode dial 2.

  Since the wall 50 has a width of about two positions, the number of positions where the user can switch without difficulty by the continuous rotation operation is two. In order to switch from “I” to “F” in which the mode setting unit 15 of the imaging device 1 does not instruct switching, it is necessary to rotate three consecutive positions. For this reason, the user can not practically perform the dial operation for switching “I” → “F”. Therefore, according to the present embodiment, the user can change the mode without noticing that the user has passed through the unintended code in any case.

  The further away the position of the unintended cords arranged in the conductive pattern 5 is from the position of the cord change which does not conform to the rules of the Gray cord, the smaller the required width of the wall 50 preventing continuous rotation operation. In addition, as the number of positions increases, the distance between the position of an unintended code disposed on the conductive pattern 5 and the position of a cord change not conforming to the Gray code rule can be increased.

  Next, the relationship between the width of the wall 50, the number of positions, and the position of unintended chord change will be described. In the present embodiment, the wall 50 has a width W of a predetermined angular range with respect to the rotation center 31 of the phase segment 6. Preferably, the predetermined angle range is equal to or more than an angle formed by two setting positions adjacent to each other in the mode dial 2 with respect to the rotation center 31 of the phase segment 6. Here, the number of positions of the mode dial 2 (number of set positions) is n (n is an odd number), and an integer of 1 or more is a. In addition, counting from the first or nth setting position, the setting position (position) corresponding to a code (combination of signal levels) which may be erroneously output, that is, the second to n of two unintended codes. Let P (P is an even number) be one of the first set positions. At this time, preferably, the following formula (1) is satisfied.

  Also preferably, the width W [°] of the wall 50 required at this time satisfies the following conditional expression (2).

  When the number of positions is set large, the width W of the wall 50 can be narrowed. For example, it is also possible to use the operation unit 14 as the wall 50.

  As described above, in the present embodiment, the electronic dial device 100 (the imaging device 1) has the wall 50 provided on a part of the periphery of the mode dial 2. The wall 50 is provided to prevent the user from continuously rotating the mode dial 2 by a predetermined amount or more (a predetermined angle or more). Preferably, the mode setting means 15 sets one of the plurality of modes based on a combination of a plurality of signal levels in accordance with the contact position of the phase segment 6 and the conductive pattern 5. The first mode (modes I and A) and the second mode (mode F) among the plurality of modes are modes corresponding to non-adjacent set positions of the mode dial 2. The mode setting means 15 controls not to switch from the first mode to the second mode, when the first mode is directly switched to the second mode by the rotation operation of the mode dial 2. Preferably, among the setting positions of mode dial 2, the setting position (positions P1 and P9) corresponding to the first mode and the setting position (position P6) corresponding to the second mode are rotations of phase segment 6 It has an angle of at least a predetermined angle (for example, 90 degrees or more) with respect to the center 31.

  Preferably, the signal level is an H level or an L level output according to the contact state between each of conductive patterns 5 (a plurality of conductive regions) and phase segment 6. Preferably, when the setting position of the mode dial 2 is the first setting position (P1), the combination of the plurality of signal levels is the first combination (C1: HHHH). When the setting position changes from the first setting position to the second setting position (P2) adjacent to the first setting position, the combination of the plurality of signal levels is one signal level with respect to the first combination. The second combination (C2: LHHH) differs only by

  In this embodiment, it is preferable to use a code in which all signal levels are LOW, that is, a code arrangement that does not use the combination of signal levels “LLLL”. That is, at least one of the plurality of signal levels is H level for each of all combinations of the plurality of signal levels. The present embodiment is configured by a combination of a substrate in which five signals obtained by adding a GND signal to four signals are arranged in a conductive pattern of four circumferences, and a phase contact piece having four contacts. One of the contacts is always in contact with the conductive region of the GND signal in any phase (position). Therefore, in order to apply the code arrangement in which all the signals are LOW, it is necessary to further increase the contact by one place and the conductive pattern by one round. In this case, the diameter of the mode dial is increased even if the number of positions is the same. For this reason, in the present embodiment, although one code arrangement is required in addition to the number of positions, it is preferable to use a code arrangement which does not use a code for which all signals are LOW.

  As described above, according to the present embodiment, it is possible to provide an electronic dial device capable of generating a stable signal without sacrificing operation feeling.

  As mentioned above, although the 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.

  In the present embodiment, the imaging device has been described as the electronic device provided with the electronic dial device. However, the present invention is not limited to this, and the electronic dial device can be applied to electronic devices other than the imaging device.
