Description

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

Conventionally, electronic devices such as digital cameras, video cameras, and personal digital assistants are provided with electronic dial devices for setting operation modes and various settings. The electronic dial device is configured by fixing a substrate provided with a conductive pattern to the main body of the device and fixing a leaf spring-shaped phase contact piece that slides with respect to the conductive pattern according to the rotation of the dial to the dial. ing. Further, it has a plurality of click grooves arranged side by side in the rotation direction and a sphere that engages with these click grooves, and by engaging and disengaging the sphere and the plurality of click grooves according to the rotation of the dial. , The rotation operation of the dial is designed to generate a click feeling.

Such a dial device determines the position of the dial by detecting the energization state between the conductive pattern and the phase contact piece. Further, the electronic dial device may reduce the number of electric signals with respect to the number of positions by using the Gray code. Gray code switches from "active" to "inactive" or from "inactive" to "active" in order to prevent erroneous output when moving to an adjacent position. A code array is a prerequisite. However, if the number of positions is odd, the above premise does not hold between some positions, and there is a possibility that an erroneous output will occur when moving to an adjacent position.

For example, Patent Document 1 discloses a rotary switch of a code output type that can surely solve the problem of erroneous output between positions when the switch is switched. By providing a definite signal terminal that outputs a definite signal, erroneous output can be suppressed.

In addition, there is also a technique for suppressing erroneous output by setting the number of positions to n (odd number) and the number of codes to n + 1 by providing a conductive pattern having two code arrays between one position out of n (odd number). It is known.

Japanese Unexamined Patent Publication No. 2006-250566

However, in the rotary switch disclosed in Patent Document 1, since the confirmation signal is arranged on the sliding portion at a certain interval or more, the conductive pattern may be peeled off due to sliding wear. In order to avoid peeling of the conductive pattern, an insulating sheet may be arranged at the end of the conductive pattern, but in that case, the dial operation feeling may be deteriorated due to the step of the insulating sheet. Further, since a phase is generated in which the definite signal and the phase contact piece do not touch each other, the phase contact piece temporarily becomes an electrically suspended metal, and the signal may be unstable and fluctuate.

On the other hand, in the above-mentioned known technique, there is a place where the cord is switched between one position, and a place without a conductive pattern, that is, a groove is formed on the substrate. Since the groove is formed not in the center of the two positions with a high click load but in one position with a low click load, the user tends to feel a step during the rotation operation, and there is a concern that the operation feel may be deteriorated.

Therefore, an object of the present invention is to provide an electronic device capable of stable mode change without sacrificing the operation feeling of the electronic dial device .

The electronic device as one aspect of the present invention includes a rotation operating member, a conductive member that rotates due to the rotation of the rotation operating member, and a plurality of signals whose signal levels change between active and inactive depending on the contact position of the conductive member. An electronic dial device capable of outputting the 1st to nth codes having different combinations of signal levels of a plurality of signals at each of the 1st to nth rotation positions of the rotation operation member. And a mode setting means for setting different modes for each of the first to nth codes output from the electronic dial device. In the first to nth codes, the codes adjacent to each other have only one signal having a different signal level, and n is an odd number. The electronic dial device has a combination of signal levels with the 1st to nth codes as a code adjacent to each of the 1st and nth codes between the 1st and nth rotation positions of the rotation operation member. It is possible to further output the n + 1th code, which is different and differs from the 1st and nth codes only in the signal level of one signal. The mode setting means sets the same mode as the mode corresponding to the first or nth code for the n + 1th code. After the 1st or nth code was output from the electronic dialing device, the Pth code not adjacent to the 1st and nth codes was output without outputting the n + 1th code. In that case, the mode is not changed to the mode corresponding to the Pth code. In the electronic dial device, the P-th rotation position of the rotation operation member from which the P-th code is output is separated from each of the first and n-th rotation positions by 90 degrees or more in the rotation direction. It is characterized in that a wall is provided in a part around the rotation operation member to prevent a continuous rotation operation from the first and nth rotation positions to the Pth rotation position of the rotation operation member .

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, the outline of the image pickup apparatus in this embodiment will be described with reference to FIG. FIG. 1 is a perspective view of an image pickup device (digital single-lens reflex camera) 1. On the upper surface of the image pickup apparatus 1, a mode dial (rotation operation member) 2 for setting various shooting conditions in shooting is arranged. The mode dial 2 is a shooting mode for setting shooting conditions such as a shutter speed priority mode (Tv mode) and an aperture value priority mode (Av mode) by rotating clockwise or counterclockwise according to the user's rotation operation. (Mode) can be selected (set). Reference numeral 3 is an exterior cover provided on the upper surface side of the image pickup apparatus 1. In the present embodiment, an interchangeable lens (imaging optical system) (not shown) can be detachably attached to the image pickup apparatus 1. However, the present embodiment is not limited to this, and can be applied to an image pickup device in which an image pickup optical system and an image pickup device 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. Reference numeral 6 is a phase contact piece (conductive member) that rotates together with the mode dial 2, and reference numeral 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 the same number of valleys as the rotation phase of the mode dial 2, and the click ball 8 engages with the valleys to generate a click feeling when the mode dial 2 is rotated. The coil spring 9 has a role of urging the click ball 8 to 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 rotation phase (number of states) of the mode dial 2 is printed. By matching the design of the mode dial cap 10 with the index 11 of the exterior cover 3, it is clearly shown to the user which shooting mode is selected (set). The power lever 12 is a member for turning on / off the power of the image pickup apparatus 1. The power lever 12 is provided with an operation unit 14 for the user to pick up and turn on / off the power supply with a finger. The leaf spring 13 engages with the valley portion of the inner wall surface of the power lever 12, and causes a click feeling when the power is turned on / off. The storage means (memory) 16 stores a code sequence table (code table) shown in FIG. 6 described later. The mode setting means (control unit) 15 has a plurality of modes (in FIG. 6) according to the setting positions of the mode dial 2 (positions P1 to P9 shown in FIG. 6) based on the code table stored in the storage means 16. The indicated modes A to I) can be selectively set.

Next, with reference to FIG. 3, the relationship between the rotation 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 the total of the modes "A", "B", "C", "D", "E", "F", "G", "H", and "I". Nine kinds of modes are shown corresponding to the positions (set positions) P1 to P9 of the mode dial 2. In the present embodiment, the positions corresponding to the shooting modes A to I and arranged at intervals of the rotation angle of 40 deg are P1 to P9, respectively.

The user can freely switch between nine 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 that cannot be operated during a clockwise or counterclockwise operation. Therefore, the user can continue to rotate the mode dial 2 in any of the clockwise and counterclockwise rotation directions.

Next, with reference to FIG. 4, the configuration of the phase contact piece (conductive member) 6 in the present embodiment will be described. 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 6a, 6b, 6c with the conductive pattern 5 are formed. 6d is provided. The distances from the center of rotation of the mode dial 2 to the contacts 6a, 6b, 6c, and 6d are all different from each other, and the rotation loci of the four contacts 6a to 6d do not 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. Further, all the contacts 6a to 6d each have two split contacts. This is because even if one of the split contacts cannot conduct with the conductive pattern 5 due to foreign matter such as dust, the other split contact maintains the conductive state. The straight line L1 connecting the contact 6a and the contact 6c and the straight line L2 connecting the contact 6b and the contact 6d are set on a straight line passing through the rotation center 31 of the phase section 6. Further, the straight line L1 and the straight line L2 are set at positions opposite to each other with respect to the rotation center 31 of the phase section 6. 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 section 6 as much as possible, and also suppresses the poor feel when the user rotates the mode dial 2. Because.

Next, the flexible substrate 4 provided with the conductive pattern 5 will be described with reference to FIG. 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 (plurality of conductive regions) isolated from each other, and the phase contact pieces 6 are slidably contacted with each other according to the rotation of the mode dial 2. Of the five signal areas, one is a reference potential signal (GND signal) area. 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 the four signal potentials (plural signal levels) is switched between active and inactive according to the rotation phase (rotation position) of the mode dial 2 according to the position (position) of the phase contact piece 6. Can be done. Here, active means a state in which the signal level indicates a HIGH level (H level), that is, "1" (first state), and inactive means a signal level indicates a LOW level (L level), that is, "0". It is a state (second state). Whether each of the four signal potentials is H level or L level is detected by a detection unit (not shown). Then, the mode setting means 15 instructs to switch to the mode selected by the user.

In the case of the mode dial 2 having n modes, it is conceivable to arrange the conductive pattern 5 (plurality of conductive regions) having n kinds of signal level combinations. 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 image pickup apparatus 1 becomes large. Therefore, a Gray code capable of reducing the number of signals by converting the number of modes n into a combination of signal levels “0” (LOW) and “1” (HIGH), a so-called binary number, is used. In the binary number, 1 is replaced with the above-mentioned signal potential HIGH, and 0 is replaced with the above-mentioned signal potential LOW. Further, the Gray code has a rule that only one signal level among a plurality of signals always changes when shifting to an adjacent code. Hereinafter, in the description of the code (signal level), if the potential of the signal is HIGH, it is referred to as “H” (H level), and if the potential of the signal is LOW, it is referred to as “L” (L level). Further, the code arrangement (combination of a plurality of signal levels) is described in the order of "signal 1, signal 2, signal 3, signal 4".

9 (a), 9 (b), and 9 (c) are plan views of a flexible substrate having a conductive pattern that does not comply with the Gray Code rules as a comparative example. Since the contact 6d is connected to the conductive region of the GND signal (the conductive region that outputs the signal GND), the signal level for the remaining contact 6a, the contact 6b, and the conductive region 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 rotates in the counterclockwise rotation direction 20 with the rotation center 31 as the axis, and the code “HLHH” is shown. It is a figure which is about to move to a conductive region. Specifically, the signal 4 in which the conductive region (third conductive region) in contact with the contact 6a is in contact with the conductive region (fourth conductive region) in contact with the contact 6b is from L to H. Two signals are about to change from L to H at the same time.

FIG. 9B shows a case where 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 coincide with each other. It is a figure at the moment when the phase contact piece 6 rotates in the rotation direction 20 and shifts to the conductive region of the code "HLHH". If the above conditions are satisfied, it is possible to change the two signals "signal 3" and "signal 4" at the same time in a strict sense. However, considering the variation in the shape and assembly of the parts, it is unlikely that the above conditions are satisfied, and in most cases, the signals change one by one in order. There are two ways to change.

"HLLL"->"HLLLH"->"HLHH" ... Order (1)
"HLLL"->"HLHL"->"HLHH" ... Order (2)
In FIG. 9 (c), the center 30 of the conductive pattern 5 and the rotation center and 31 of the phase contact piece 6 are displaced from each other, and the sequence (2) is shown during the transition from “HLLL” to “HLHH”. It is a figure of the moment passing through "HLHL". Both "HLLH" in the sequence (1) and "HLHL" in the sequence (2) are unnecessary codes that are not intended when setting the mode.

Gray code must adhere to the rule that only one signal changes when transitioning to an adjacent code as described above. However, with a dial having an odd number of positions n (number of modes) and no rotation end point, such as the dial described in the present embodiment, there will always be places where the Gray Code rule cannot be observed.

With a dial having no end point of rotation, in addition to the movement between adjacent positions such as position P1 and position P2, the movement between position P1 and position P9 is added. Therefore, the codes arranged at the positions P1 and P9 also correspond to the codes adjacent to each other. If one signal is changed from H to L with a dial that does not have a rotation end point, for example, when moving to an adjacent signal, it will continue to rotate in the same rotation direction and will always be the same until it is changed to the same position again. The signal must be changed 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 code changes must be an even number. When the number of positions n corresponding to the number of modes (the number of set positions of the mode dial 2) is an even number, the number of times the code changes when rotating from the position P1 to the position Pn is (n-1) times. If the mode dial 2 does not have a rotation end point, the code changes once between the position P1 and the position Pn. That is, the total number of times the code changes is n times. That is, it always has an even number of code changes, and it is possible to set a code array that observes the rules of Gray code.

On the other hand, when the number of positions n (the number of set positions) corresponding to the number of modes is an odd number, the number of times the code changes from the position P1 to the position Pn is (n-1) times (even number of times). Further, when 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 total number of code changes is n times (odd number). That is, there will always be an odd number of code changes, and there will always be one place where the Gray Code rules cannot be observed.

FIG. 10 is a Gray code sequence listing as a comparative example when the number of positions is 9. As mentioned above, since the number of positions (number of modes) is odd, the Gray code rule is not observed. It is assumed that the user rotates the mode dial to change the position P9 in which the mode I is set to the position P1 in which the mode A is set. At that time, since the two signals are rarely switched at the same time, the signals change one by one in order. There are two orders.

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 the mode D assigned to the position P4 or an order (4) via the mode H assigned to the position P8 occurs. That is, when the user rotates the mode dial 2 and changes the mode from mode A to mode I or from mode I to mode A, the user rotates only one position, but the mode is in the middle of the operation. The mode may be changed to D or mode H. In particular, when the user slowly performs the rotation operation or stops the rotation in the middle of the rotation, it is easy for the user to recognize the change to the unintended mode. For this reason, it is not preferable that there is a part where the mode is switched to a mode not intended by the user during rotation.

Next, the configuration of the present embodiment for solving the problem peculiar to the mode dial having an odd number of positions will be described. The code sequence listing in this embodiment will be described with reference to FIG. FIG. 6 is a code arrangement table in the present embodiment, and shows the relationship between the position (position), the mode (shooting mode), and the code of the code arrangement. As shown in FIG. 6, 10 codes are prepared by adding 1 to the number of modes as the codes to be assigned to the mode dial 2 having 9 positions and 9 modes. At this time, the 10 codes are arranged differently from each other (combination of a plurality of signal levels different from each other). Further, there is only one type of signal that always changes when moving to an adjacent code between codes C1 to C10 (only one of the four signal areas (signals 1 to 4) changes). The code array is. In addition, even when the code is moved from the code C10 to the code C1, the code arrangement is such that only one type of signal changes.

Here, the conductor pattern is created from the code C1 to the code C9, and the conductor pattern related to the code C10 is not created. Then, as in the conventional case, modes A to I are assigned to the codes C1 to C9, respectively. In the present 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 code C10 is assigned the same mode I as the code C9.

Next, the flexible substrate 4 having the conductive pattern 5 in the present embodiment will be described with reference to FIG. 7. FIG. 7 is a top view of the flexible substrate 4 having the conductive pattern in the present embodiment. FIG. 7A shows a diagram in which the phase contact piece 6 is arranged at the position P9, and FIG. 7B shows a diagram in which the phase contact piece 6 is arranged at the position P1. The operation of the user rotating the mode dial 2 in the rotation direction 20 to change from the position P9 to the position P1 is an operation of changing two signal levels (signals 3 and 4 in this embodiment). Not in line.

FIG. 8 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. 8, an order (5) via the signal level combination “HHLH” of the code C10 and an order (6) via the signal level combination “HHHL” of the code C6 occur. However, the signal level combination "HHLH" of the code C10 is an array (combination) different from any of the codes C1 to C9. Therefore, during the operation of the mode dial 2, the mode is not switched to any of the modes assigned to the codes C1 to C9. Further, the same mode as 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 the order (5), the mode changes in the order of "I"-> "I"-> "A". The change from "I" to "I" is equivalent to the fact that the shooting mode of the image pickup apparatus 1 has not been changed. Therefore, the user can change the mode without noticing that the code C10 has been passed through.

On the other hand, in the case of the order (6), since the combination "HHHL" of the signal levels of the code C6 passes through the array (combination) of the code C6, the mode changes in the order of "I" → "F" → "A". do. Therefore, the user may notice the switch to the mode F when the mode dial 2 is operated from the position P9 to the position P1 particularly slowly. When a signal for switching the mode from "I" to "F" or "A" to "F" is detected in this way, the mode setting means 15 controls so as not to instruct the mode to be switched to "F". There is a need. However, in that case, if the user actually performs the operation of switching the mode from "I" → "F" or "A" → "F" quickly and continuously without going through any other mode, the mode May not switch to "F".

Therefore, in the present embodiment, as shown in FIG. 12, a wall (wall portion, convex portion, protruding portion) 50 for preventing the user from continuously rotating the mode dial 2 is provided in a part around the mode dial 2. .. FIG. 12 is a top view of the electronic dial device 100 according to the present embodiment.

As shown in FIG. 12, it is a general rotation operation method for a user to sandwich 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, either the finger 40 or the finger 41 hits the wall 50, and it becomes 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 that the user can easily switch by the continuous rotation operation is two. The mode setting means 15 of the image pickup apparatus 1 does not instruct the switching. In order to switch from "I" to "F", continuous rotation of three positions is required. Therefore, the user cannot substantially perform a dial operation for switching from "I" to "F". Therefore, according to the present embodiment, the user can change the mode without noticing that the unintended code has been passed in any case.

The farther the position of the unintended cord placed in the conductive pattern 5 is from the position of the cord change that does not follow the rules of the Gray code, the smaller the required width of the wall 50 to prevent the continuous rotation operation. Further, as the number of positions increases, the distance between the position of the unintended code arranged in the conductive pattern 5 and the position of the code change that does not follow the rules of the Gray code can be increased.

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

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

When a large number of positions are set, the width W of the wall 50 can be narrowed. For example, the operation unit 14 can be used as the wall 50.

As described above, in the present embodiment, the electronic dial device 100 (imaging device 1) has a wall 50 provided in a part around the mode dial 2. The wall 50 is provided so as 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 the combination of the plurality of signal levels according to the contact position between the phase section 6 and the conductive pattern 5. Of the plurality of modes, the first mode (modes I and A) and the second mode (mode F) are modes corresponding to the 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. Further, preferably, among the set positions of the mode dial 2, the set positions corresponding to the first mode (positions P1 and P9) and the set positions corresponding to the second mode (position P6) are the rotations of the phase section 6. It has an angle of a predetermined angle or more (for example, 90 degrees or more) with respect to the center 31.

Preferably, the signal level is an H level or an L level that is output depending on the contact state between each of the conductive patterns 5 (plurality of conductive regions) and the phase section 6. Further, 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 set position changes from the first set position to the second set position (P2) adjacent to the first set position, the combination of the plurality of signal levels is one signal level for the first combination. Only the second combination (C2: LHHH) is different.

In the present 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 signal level combination “LLLL”. That is, for each of all combinations of the plurality of signal levels, at least one of the plurality of signal levels is the H level. The present embodiment is composed of a combination of a substrate in which five signals obtained by adding a GND signal to four signals are arranged in a conductive pattern on 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 signals are LOW, it is necessary to increase the number of contacts by one and the circumference of the conductive pattern by one more. In that case, the diameter of the mode dial becomes large even if the number of positions is the same. Therefore, in the present embodiment, one code array is required in addition to the number of positions, but it is preferable to use a code array that does not use a code in 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 the operation feeling.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the gist thereof.

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