Description

The present invention relates to an electronic device such as a digital camera, and particularly to an electronic device having an operation member that can be rotated.

Electronic devices such as digital cameras have various functions. For example, a digital camera has functions such as focus adjustment of a photographing lens, change of zoom magnification, and photographing mode such as aperture-priority or shutter-speed-priority automatic exposure mode. Then, the housing is provided with an operation member for selecting each function and changing various set values included in each function.

In the case of a portable electronic device, there is a portable electronic device in which a plurality of functions can be changed with a single operation member in order to prevent an increase in size. For example, in a digital camera, the function of setting continuous values such as focus adjustment and zoom magnification of a shooting lens and the function of setting discrete values such as aperture value and shutter speed are used as one operation member. , It is possible to reduce the number of operation members required from two to one.

As such an operation member, as in Patent Document 1, a rotatable operation member is provided around the lens barrel on the front surface of the device body, and there are two states: a restricted state with rotation regulation and a non-regulated state without rotation regulation. There is one that can be switched by the switching means.

JP, 2014-21245, A

However, in the configuration of Patent Document 1, a state confirmation detector is installed in order to confirm two states, a regulated state with rotation regulation and an unrestricted state without rotation regulation. The detector detects which state it is in by detecting the position of the switching means. Therefore, not only the detector but also many parts such as a member for fixing the detector are required, and the size of the camera body may be increased.

The state in which the rotation of the operation member is restricted refers to a state in which the operation resistance changes periodically during the rotation operation of the operation member, that is, a so-called click feeling occurs. Further, the state without rotation restriction refers to a state in which the operation resistance is substantially constant and there is no click feeling when the operation member is rotated. Hereinafter, a state in which a click feeling occurs will be referred to as a click-ON state, and a state in which a click feeling does not occur will be referred to as a click-OFF state.

Therefore, an object of the present invention is to provide a rotary operation member capable of switching the presence/absence of a click feeling at the time of operation, and an electronic device for detecting whether the operation member is in a click ON state or a click OFF state without increasing the number of parts. To provide.

When the rotation operation member is rotationally operated, the sound is collected from the microphone member. A sound is recorded, and when the click sound generated when the rotation restriction is in the restricted state is input to the recorded sound, it is determined that the rotation restriction member is in the rotation restricted state.

Next, the configuration of the front cover unit 2 of FIG. 1A will be described with reference to FIGS. 2 and 3.

2 is an internal structural view of the front cover unit 2, and FIG. 3 is an exploded perspective view of the front cover unit 2.

As shown in FIGS. 2 and 3, the front cover unit 2 includes a front cover 202, which is an outer cover of the digital camera 1, an operation ring 201, an operation ring holding member 203, which will be described later, a base member 204, a switching operation member 205, and an annular shape. A member 206 is provided. Further, the front cover unit 2 includes a click generating mechanism, a click switching mechanism, and a rotation detecting means which will be described later. Photo-interrupters PI1 and PI2, which will be described later, are mounted on the flexible detection substrate 211 and are electrically connected to the signal processing substrate (not shown) by a connector or the like.

In FIG. 3, the base member 204 includes a double-sided tape or a double-sided tape on the inner surface of the front cover 202 in a state where the cylindrical portion 204 a provided on the base member 204 projects from the circular cutout portion 202 a formed in the front cover 202. It is fixed with an adhesive or the like.

The operation ring holding member 203 rotatably sandwiches the switching operation member 205 together with the base member 204, and the inner peripheral portion 203a of the operation ring holding member 203 is fitted into the cylindrical portion 204a of the base member 204, so that the base member 204 It is fixed with screws.

The operating ring 201 is provided with a cylindrical portion 201b, which is rotatably fitted to an outer peripheral portion 203b formed on the operating ring holding member 203. Further, a so-called flange-shaped annular member 206 having a cylindrical portion and a disc portion and the operation ring 201 sandwich the front cover 202, the base member 204, and the operation ring holding member 203. In the front cover 202, the base member 204, and the operation ring holding member 203, a plurality of engagement arms 206c provided on the cylindrical portion of the annular member 206 engages engagement claws 201a provided on the operation ring 201. Doing so will prevent it from slipping out.

By such engagement, the operation ring 201 is rotatably attached to the front cover 202 together with the annular member 206. On the other hand, in the disc portion of the annular member 206, a plurality of openings 206a that are cut out in a predetermined shape on the outermost periphery and a plurality of non-openings 206b that are portions without cutouts are formed at equal intervals in the circumferential direction. .. The opening portion 206a and the non-opening portion 206b are used for a click generating mechanism and a rotation detecting means described later.

Next, details of the click generating mechanism, the click switching mechanism, the rotation detecting means, and each component will be described.

A click generation mechanism for generating a click feeling of the operation ring 201 and a click switching mechanism for switching the click ON state and the click OFF state of the operation ring 201 will be described with reference to FIGS. 2 to 8.

FIG. 4 is an exploded perspective view of the click generating mechanism.

The click generating mechanism includes a steel ball 207 that reduces frictional resistance, a click member 209, and a biasing spring 208 that biases the steel ball 207 and the click member 209 in order to realize a smooth operation feeling. The steel ball 207, the urging spring 208, and the click member 209 are movably inserted into the through hole 204b provided in the base member 204, and the click member 209 side abuts a switching plate 210 or an annular member 206 described later, The ball 207 side is in contact with the switching operation member 205. The tip shape of the click member 209 on the switching plate 210 side is spherical. The click generation mechanism is for generating a click when the click switching mechanism or the operation ring 201 described later is operated.

5(a) and 5(b) are AA cross sections in FIG.

The click switching mechanism includes a switching plate 210 described later and a switching operation member 205 that holds and fixes the switching plate 210 described later. The switching operation member 205 has an engaging groove 205a and an engaging groove 205b, and a shallow sliding groove 205c connecting the engaging groove 205a and the engaging groove 205b. The steel ball 207 is urged by the urging spring 208 and comes into contact with the engagement groove 205a or the engagement groove 205b, so that the switching operation member 205 changes the operation ring 201 between the click-on state and the click-off state. Hold.

FIG. 6 is an enlarged view of portion D of FIG. 2, and the annular member 206 is not shown for the sake of explanation. The switching plate 210 is provided with a first through hole 210a and a second through hole 210b, and the through holes are connected by a slit 210c. Since the first through hole 210a and the second through hole 210b are smaller than the spherical shape of the tip of the click member 209, the click plate 209 is fixed to the switching operation member 205. Can be held. Further, as will be described later in detail, the first through hole 210a is smaller than the second through hole 210b.

Here, the click OFF state of the operation ring 201 will be described.

FIGS. 5A and 6A show a position where the switching operation member 205 is in the click OFF state, and the click member 209 is attached to the first through hole 210 a of the switching plate 210 by the biasing spring 208. It is energized. At the same time, the steel ball 207 is biased by the biasing spring 208 to the engagement groove 205a of the switching operation member 205. In order to move the steel ball 207 fitted in the engagement groove 205a to the shallow sliding groove 205c, a force for compressing the biasing spring 208 is required. Therefore, the switching operation member 205 easily rotates. It is in a state of being held so as not to.

In addition, the first through hole 210 a of the switching plate 210 is sufficiently smaller than the spherical shape of the tip of the click member 209, and holds the tip of the click member 209 so as not to contact the annular member 206. Therefore, in the click-off state, since the load change due to the rotation does not occur in the annular member 206, the operation ring 201 integrated with the ring member 206 can also be smoothly operated without load change. There is.

Next, the click ON state of the operation ring 201 will be described.

5(b) and 6(b) show the position where the switching operation member 205 is in the click ON state.

When the switching operation member 205 is slid counterclockwise when viewed from the front of the digital camera 1 of the present embodiment from the above-mentioned click OFF state, the steel ball 207 rides up from the engagement groove 205a to the shallow sliding groove 205c. When the switching operation member 205 is slid further, the steel ball 207 is fitted into the fitting groove 205b, and the state shown in FIGS. 5B and 6B is obtained. The steel ball 207 is biased by the biasing spring 208 toward the fitting groove 205b, whereby the position of the switching operation member 205 is held. At the same time, the contact portion between the click member 209 and the switching plate 210 slides from the first through hole 210a of the switching plate 210 along the slit 210c and moves to the second through hole 210b. At that time, the click member 209 passes through the second through hole 210b of the switching plate 210 and is in a state of urging the annular member 206.

The second through hole 210b has a size such that the tip end portion of the click member 209 pops out by a fixed amount, and the pop-out amount is set to an amount that sufficiently urges the annular member 206 and the opening 206a. Hereinafter, a state in which the click member 209 is biased by the biasing spring 208 toward the opening 206a is hereinafter referred to as a click position. When the operation ring 201 is rotated in this state, the annular member 206 integrated with the operation ring 201 is also rotated, and when the click member 209 comes out of the click position, the biasing spring 208 is also compressed, so that a large load is applied. Occurs.

Further, since the biasing spring 208 is not compressed when the click member 209 contacts the non-opening portion 206b and when the non-opening portion 206b moves to the click position, only a small load is applied to the rotation of the annular member 206. Therefore, in the click-on state, when the user rotates the operation ring 201, a large load variation, that is, a feeling of click is felt at each click position, and it is possible to perform a stepwise operation between the click positions. Has become.

Next, the rotation detecting means for detecting the rotation amount of the operation ring 201 will be described.

FIG. 7A is an enlarged view of portion E in FIG. 2, and the holding member 212 is not shown for the sake of explanation. The arrow B in the drawing indicates the rotation direction of the annular member 206 and the operation ring 201, and the clockwise direction and the counterclockwise direction are indicated as C and CC with respect to the paper surface.

The rotation detecting means is composed of first and second photo interrupters PI1 and PI2 (hereinafter abbreviated as PI1 and PI2) mounted on the flexible detection substrate 211. The photo interrupter has a light emitting unit and a light receiving unit, and converts the amount of light received by the light receiving unit into a magnitude of an electric signal and outputs the electric signal.

The light emitting unit and the light receiving unit of PI1 and PI2 are provided on the base member 204 at different phases with respect to the opening 206a or the non-opening 206b of the annular member 206 so that the rotational phase of the annular member 206 can be detected. It is fixed.

In FIG. 7B, the annular member 206 rotates and the opening 206a and the non-opening 206b pass between the light-emitting portion and the light-receiving portion in PI1 and PI2. It is the figure which showed change. When the light receiving parts of PI1 and PI2 are not shielded from light, the outputs of PI1 and PI2 are high, and this state is expressed as an H signal. When the light receiving portions of PI1 and PI2 are shielded from light, the outputs of PI1 and PI2 become small, and this state is expressed as an L signal. At the click position, PI1 and PI2 are arranged so that the output signals of PI1 and PI2 are L and L, respectively.

Then, as shown in FIG. 7A, by arranging the light emitting portions and the light receiving portions of PI1 and PI2 in different phases with respect to the opening 206a, as shown in FIG. 7B, PI1 and PI2 are provided. The H signal and the L signal are output in a state where they are out of phase by half.

FIG. 7C is a table showing the signals detected by PI1 and PI2 at the opening 206a and the non-opening 206b of the annular member 206 when the operation ring 201 is rotated, and the determination of the rotation direction. .. For example, in FIG. 7B, when the operation ring 201 is rotated in the C direction from the click position, the output waveforms of PI1 and PI2 move to the left in the figure, and the output signal of PI1 becomes H first. Then, as shown in the table of FIG. 7C, it is determined that the rotation is in the C direction. When rotated in the CC direction, the output signal of PI2 becomes H first, and it is determined that the signal is rotated in the CC direction as shown in the table of FIG. 7(c).

FIG. 8 is a block diagram showing the configuration of the digital camera 1. It should be noted that the functions described in FIG.

The image pickup element 113 is a CCD or a CMOS image sensor for photoelectrically converting an optical image to generate an analog video signal, and is attached to the taking lens barrel 3. The A/D converter 120 is mounted on a signal processing board (not shown) mounted inside the digital camera 1, and converts the analog video signal generated by the image sensor 113 into a digital video signal. The image processing unit 121 is mounted on the signal processing board (not shown) and converts the digital video signal obtained by the A/D conversion unit 120 into predetermined image data. The converted image data is finally stored in the recording medium 119 which is detachable from the recording medium slot including the card I/F 114 mounted on the signal processing board (not shown).

Further, on the signal processing board (not shown), a system control unit 115 that controls the entire digital camera 1 and executes a program, and a nonvolatile memory 116 that can electrically erase and record the program and the like are mounted. Here, the program is a program for executing various flowcharts described later in this embodiment. Further, on the signal processing board (not shown), a system memory 117 for expanding a program read from the non-volatile memory 116 and a system timer 118 for measuring the time used for various controls and the time of a built-in clock are mounted. There is.

Next, a click detection means for detecting whether the operation ring 201 is in the click-OFF state or the click-ON state will be described with reference to FIGS. 9 and 10. FIG. 9 is a diagram showing an example of changes in the speed v when the operation ring 201 is rotated from a stationary state with a constant operation force. 9A shows a click OFF state, and FIG. 9B shows a click ON state. In the graph, the horizontal axis represents time t and the vertical axis represents rotation speed v.

When the operation ring 201 is in the click-off state, the operation ring 201 can be operated smoothly without load fluctuation as described above. Therefore, as shown in FIG. It fluctuates.

On the other hand, when the operation ring 201 is in the click ON state, the operation ring 201 operates with a large load change as described above. Therefore, as shown in FIG. 9B, the operation ring 201 has a rotational speed for each click position. v increases and decreases instantaneously.

That is, the presence or absence of a click can be determined by detecting the change in the rotation speed v of the operation ring 201 described above. That is, when the change in the rotation speed v of the operation ring 201 is substantially constant or small, it can be determined that the operation ring 201 is in the click-off state, and when the change in the rotation speed v of the operation ring 201 is large, the determination is in the click-on state.

Next, the operation flow of the click detection means of the digital camera 1 of FIG. 8 will be described with reference to FIGS. 10 and 11. In the operation flow of FIG. 11, unless otherwise specified, the program recorded in the nonvolatile memory 116 is read into the system memory 117 and executed by the system control unit 115.

First, when the user presses the power button 101, the digital camera 1 is activated, and a shooting standby state is detected in which it is detected that each operation unit such as the power button 101, the release button 102, and the operation ring 201 is operated. It is assumed that the operation flow of FIG. 11 is started.

In the shooting standby state, it is first determined in step S300 whether an operation member other than the operation ring 201 has been operated. If it is determined that the operation member other than the operation ring 201 has been operated, the process proceeds to the operation member (S400), the process corresponding to the operated content is performed, and then the process returns to the shooting standby state. If it is determined in S300 that the operation ring 201 has been operated, the process proceeds to step S301.

In step S301, it is determined whether the output signal of either PI1 or PI2 is H. As shown in FIG. 7C, since the output signals of both PI1 and PI2 are L in the click ON state, if either of the output signals of PI1 and PI2 is H, the operation ring 201 stops at a position other than the click position. Will be.

That is, when the output signal of PI1 or PI2 is determined to be H in step S301, the process proceeds to step S302, it is determined to be in the click-OFF state, and the process proceeds to step S303. In step S303, the process proceeds to a process of performing continuous adjustment such as focus adjustment, and after the process, the process returns to step S300 again. In step S303, the set value is changed every time H1 and L2 of PI1 and PI2 are inverted.

When the output signal of PI1 or PI2 is not H in step S301, the process proceeds to step S304. In step S304, it is determined whether or not the output signal of either PI1 or PI2 is inverted from the L signal to the H signal by operating the operation ring 201. If neither of the output signals of PI1 and PI2 is inverted within the predetermined time, it is determined that the operation ring 201 is not operated, and the process returns to step S300. When the output signal of either PI1 or PI2 is inverted from the L signal to the H signal within the predetermined time, it is determined that the operation ring 201 is being operated, and the process proceeds to step S305.

In step S305, the rotation direction of the operation ring 201 is determined based on the detected output signal information of PI1 and PI2 and the condition described in FIG. 8C, and the process proceeds to step S306.

In step S306, the times Δt1 and Δt2 until the output signals of PI1 and PI2 are inverted are measured, and the process proceeds to step S307. Here, the inversion time Δt1 and the inversion time Δt2 will be described with reference to FIG.

FIG. 10 is a diagram showing the relationship between the output signals of PI1 and PI2 and the time t when the operation ring 201 is rotated in the CC direction. FIG. 10A is a diagram showing a click OFF state, and FIG. 10B is a diagram showing a click ON state.

In FIGS. 10A and 10B, when the operation ring 201 is rotated from the click position in the CC direction, PI1 is first inverted from L to H, and then PI2 is inverted from L to H. At this time, the inversion time from the time when one of PI1 and PI2 is first inverted from L to H until the other is inverted from L to H is Δt1, and similarly either one of PI1 and PI2 is changed from H to L. The inversion time from when the other is inverted to H is inverted to L is Δt2. 10A shows that the difference in the rotation speed v is small in the click OFF state, and the difference in the rotation speed v is large in the click ON state in FIG. 10B.

Returning to FIG. 11, in step S307, the difference D between the inversion time Δt1 and the inversion time Δt2 measured in step S306 is calculated, and the process proceeds to step 308.

In step S308, the difference D is compared with the preset judgment value M. The determination value M is a constant for determining whether the operation ring 201 is in the click ON state or the click OFF state.

In step S308, when the determination value M<difference D, the amount of change in the rotation speed v is large, so the process proceeds to step S309, it is determined that the click-ON state is reached, and the process proceeds to step S310. In step S310, the process proceeds to a process of performing exposure correction adjustment, which is a separate operation, and returns to S300 again when the process ends. Otherwise, the process proceeds to S302. In step S310, the set value is changed for each click position.

When it is determined in step S308 that the relationship of the determination value M<difference D is not satisfied, the amount of change in the rotation speed v is small.

In this embodiment, when both the output signals of PI1 and PI2 are L signals at the beginning, the click OFF determination is made immediately, but it may be always compared with the determination value M.

As described above, in the rotary operation member capable of switching the presence/absence of a click feeling during operation, there is provided detection means for detecting whether the operation member is in the click state or the click-off state without increasing the number of parts. be able to.

The operation flow of the click detecting means of the digital camera 1 may be as follows. In FIG. 12, the same steps as those in the embodiment of FIG. 11 are indicated by the same numbers, and the description thereof is omitted.

In step S304, it is determined whether the output signal of either PI1 or PI2 is inverted from the L signal to the H signal by operating the operation ring 201, and either output signal of PI1 or PI2 is output for a predetermined time. If the L signal is inverted to the H signal within that time, it is determined that the operation ring 201 is being operated, and the process proceeds to step S320.

In step S320, the microphone 113 used for sound collection during normal moving image recording is turned on, and the process proceeds to step S321.

In step S321, among the sounds collected from the microphone 113, the sounds before and after the PI1 and PI2 both become L signals are recorded, and the process proceeds to step S322.

In step S322, whether or not the operation ring 201 is click-on is evaluated from the sound recorded in step S321. The evaluation is performed by comparing with a preset sound index such as a frequency band and sound pressure of a recorded sound. As the sound index, a click sound generated when the operation ring 201 described in FIGS. 1 to 6 is rotated, that is, a click generated when the click member 209 returns from the non-opening portion 206b to the opening portion 206a. It is a collision sound between the member 209 and the annular member 206.

If the sound recorded in step S321 is a collision sound similar to the index sound, the process proceeds to step S323, it is determined that the operation ring 201 is in the click ON state, and the process proceeds to step S310. If it is determined in step S322 that the sound recorded in step 321 is different from the index sound, the process proceeds to step S302, and it is determined that the operation ring 201 is in the click OFF state.

As described above, in the rotary operation member capable of switching the presence/absence of the click feeling during the operation, the detection means for detecting whether the operation member is in the click ON state or the click OFF state without increasing the number of parts is provided. can do.
