Description

[Technical field]

[0001] The present invention relates to an optical instrument such as a digital camera having a vibration device. [Background technology]

[0002] In a conventional single-lens reflex camera, when a release button is operated to take a picture, camera shooting sounds such as a shutter sound and a mirror driving sound are generated. This allows the user to recognize that the camera has taken a picture by the sound. However, in recent years, it has been considered problematic that when taking pictures of athletes, the camera shooting sound can cause the athletes to lose concentration, and that the camera shooting sound can interfere with the appreciation of the surrounding people in quiet environments such as concerts and museums. As a countermeasure to this problem, the spread of mirrorless cameras has eliminated the mirror driving sound. For this reason, among mirrorless cameras, there are silent shutter cameras that significantly reduce the camera shooting sound even when taking pictures in quiet places by making the shutter sound quieter.

[0003] However, because silent shutter cameras are nearly silent, when a user operates the release button to take a picture, it is difficult to determine whether the image has been recorded properly. To address this problem, a configuration has been disclosed that allows the release button to vibrate, suppressing the camera's shooting sound while allowing only the user to recognize the shooting operation.

[0004] Patent Document 1 discloses a camera in which a vibration device (piezoelectric actuator) is provided directly under a button such as a release button that can be pressed by the user, and the vibration device vibrates in response to the pressing operation, giving the user a feeling of operation. Patent Document 2 discloses a camera that allows the user to perceive the orientation in which a subject can be properly photographed (i.e., provides information indicating the orientation of the camera) by generating vibrations in a vibration device provided on the release button where the user places his / her finger or on a grip part that the user holds.

[0005] [Patent Document 1] JP 2013-157953 A [Patent Document 2] JP 2006-136865 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, a large amount of vibration is required to generate vibrations that the user can recognize. In addition, depending on the shooting environment and situation, such as shooting while moving or while riding in a vehicle, it may be difficult to recognize the vibration of the release button if the vibration is small. For this reason, in the configuration for vibrating the release button described in Patent Document 1 and Patent Document 2, in order to generate vibrations that the user can reliably recognize, the vibration device needs to be large, which leads to an increase in the size of the camera. In addition, a piezoelectric actuator needs to have a large number of layers and be large, so it is necessary to use a very expensive vibration device.

[0007] An object of the present invention is to provide an optical device that is inexpensive and compact in configuration and that is capable of increasing the vibration transmitted to a release button. [Means for solving the problem]

[0008] An optical instrument according to one aspect of the present invention is an optical instrument having an operating means, a vibration device that generates vibrations in response to operation of the operating means by a user, and a vibration transmission member to which the vibration device is attached, wherein the vibration transmission member has a fixing portion on one side for fixing the vibration transmission member to the optical instrument, a weight member on the other side, and an engagement portion between the fixing portion and the weight member for engaging with the operating means, and the vibration device is positioned between the fixing portion and the weight member on the vibration transmission member.

[0009] Other objects and features of the present invention will be described in the following embodiments. Effect of the Invention

[0012] Hereinafter, an imaging device (optical device) according to each embodiment will be described with reference to the accompanying drawings. EXAMPLES

[0013] A configuration of a digital camera (hereinafter, referred to as a camera) 10 as an imaging device (optical device) according to a first embodiment will be described with reference to Figs. 1 and 2. As shown in Fig. 1, in the camera 10, the optical axis direction in which the optical axis of a removable interchangeable lens 12 extends is the Z-axis direction, and the directions perpendicular to this are the X-axis direction (horizontal direction) and the Y-axis direction (vertical direction). Hereinafter, the X-axis direction and the Y-axis direction will be collectively referred to as the X / Y-axis direction. Furthermore, the rotation direction around the X-axis is referred to as the Pitch direction, and the rotation direction around the Y-axis is referred to as the Yaw direction. The Pitch direction and the Yaw direction (hereinafter, collectively referred to as the Pitch / Yaw direction) are rotation directions around two axes, the X-axis and the Y-axis, which are perpendicular to each other. Furthermore, the rotation direction around the Z-axis is referred to as the Roll direction.

[0014] 1 shows the front and top of camera 10. Camera 10 is equipped with a front cover unit 11 that constitutes the front part of the main body, and an interchangeable lens 12 that is provided in the center of front cover unit 11 and forms an image of a subject by focusing light from the subject. Interchangeable lens 12 is detachably attached to camera 10, and a mount section (not shown) is provided in the detachable section. An image sensor 126 (see FIG. 4) is provided inside the main body of camera 10, which photoelectrically converts (captures) the image of the subject to generate an image.

[0015] A front grip portion 101 for a user to hold the camera 10 in his / her hand is provided on the left side (right side when viewed from the rear) of the front cover unit 11 as viewed from the front (subject side). The front grip portion 101 protrudes forward from the surrounding area of ​​the interchangeable lens 12 in the front cover unit 11, and has a shape that allows the user to easily hold it with the hand (middle finger and ring finger). A user holding the front grip portion 101 in his / her hand can operate the release button (operation means) 16 with the index finger of the hand. For this reason, the front grip portion 101 is disposed closer to the release button 16 than the interchangeable lens 12.

[0016] On the top surface of the camera 10, a top cover unit 13 is provided as a unit constituting an external part. A power button 14 and a mode dial 15 for switching the imaging mode are arranged on the top cover unit 13. When the power of the camera 10 is OFF, the user presses the power button 14 to turn on the power of the camera 10. When the power of the camera 10 is ON, the camera 10 is ready to capture images. In this state, the user rotates the mode dial 15 and selects its rotation position (operation position), thereby allowing the user to set various imaging modes. The various imaging modes include a manual still image capturing mode in which the user can arbitrarily set imaging conditions such as the shutter speed and the aperture value, an auto still image capturing mode in which an appropriate exposure amount is automatically obtained, and a video capturing mode for capturing videos.

[0017] A vibration device 100 attached to the top cover unit 13 is provided near the release button 16 inside the camera 10. The vibration device 100 is fixed to a vibration transmission member 202 (described later) which is a component of the top cover unit 13, and a part of the vibration transmission member 202 engages with or abuts against the release button 16.

[0018] 2(a) shows the rear face of the camera 10. On the rear face of the camera 10, there are provided a rear cover unit 20 constituting the rear face of the main body, a rear operation section 21 provided on the rear cover unit 20, and a display section 22. The rear operation section 21 includes a plurality of buttons, a rotary sub-dial, etc., and is provided on the lower side of a rear grip section 20a of the rear cover unit 20 on which the user places his / her thumb when holding the camera 10.

[0019] When the power supply of the camera 10 is ON and the still image capturing mode or the video capturing mode is set, a through image of the subject image captured by the image sensor 126 is displayed on the display unit 22. The display unit 22 also displays imaging parameters indicating imaging conditions such as shutter speed and aperture value, and the user can change the setting values ​​of the imaging parameters by operating the rear operation unit 21 while watching the display. The setting values ​​of the imaging parameters may be changed by a touch operation (slide operation) on a slider displayed on the display unit 22 as a touch panel. In this case, the slider is an operation means that allows the user to operate for settings related to imaging, and also allows the user to operate to multiple operation positions (slide positions).

[0020] The rear operation section 21 includes a playback button for instructing playback of a recorded captured image, and the captured image is played back and displayed on the display section 22 when the user operates the playback button.

[0021] A mount portion (not shown) of the camera 10 is provided with an electrical contact group 108 (see FIG. 4). The camera 10 communicates with the interchangeable lens 12 attached to the mount portion and supplies power to the interchangeable lens 12 via the electrical contact group 108.

[0022] 2(b) shows the bottom surface of the camera 10. A tripod mount 30 is provided on the bottom surface of the camera 10. To the tripod mount 30, accessories such as a tripod and a jacket can be attached.

[0023] 3 is a block diagram showing the electrical and optical configuration of the camera 10. The camera 10 has a power supply unit 113 that supplies power to each unit described below, an operation unit 40 including a power button 14, a mode dial 15, and a rear operation unit 21, and a release button 16. The entire camera system consisting of the camera 10 and the interchangeable lens 12 is controlled by a system control unit 115. At this time, the interchangeable lens 12 communicates with the system control unit 115 via a group of electrical contacts 108. The system control unit 115 controls the entire camera system by reading and executing a control program stored in a memory (not shown).

[0024] The interchangeable lens 12 has a zoom unit 116 including a zoom lens that moves in the optical axis direction to change the magnification, and a lens vibration isolation unit 118 including a shift lens that moves (shifts) in the X / Y axis directions perpendicular to the optical axis to reduce (correct) image blur. The interchangeable lens 12 also has an aperture unit 122 with a light amount adjustment function, and a focus unit 124 including a focus lens that moves in the optical axis direction to adjust the focus.

[0025] The system control unit 115 controls the driving of the aperture unit 122 via an aperture drive unit 123 provided in the interchangeable lens 12 in response to the aperture setting value received from the operation unit 40 or a luminance signal acquired from the image processing unit 131. The system control unit 115 also performs autofocus by controlling the driving of the focus unit 124 via a focus drive unit 125 provided in the interchangeable lens 102 in response to a focus signal acquired from the image processing unit 131.

[0026] The camera 10 is provided with a pitch anti-shake calculation section 121a and a yaw anti-shake calculation section 121b. The pitch anti-shake calculation section 121a calculates the shift positions in the Y-axis direction of the lens anti-shake unit 118 (shift lens) and the sensor anti-shake unit 130 (image pickup element 126) using the shake signal from the pitch shake detection section 120a. The yaw anti-shake calculation section 121b calculates the shift positions in the X-axis direction of the lens anti-shake unit 118 and the sensor anti-shake unit 130 using the shake signal from the yaw shake detection section 120b. The camera 10 is provided with a sensor drive section 127 that drives the sensor anti-shake unit 130. The interchangeable lens 12 is provided with an anti-shake drive section 119 that drives the lens anti-shake unit 118. The system control unit 115 controls the shift positions of the lens vibration isolation unit 118 and the sensor vibration isolation unit 130 via the vibration isolation drive unit 119 and the sensor vibration isolation unit 130 in accordance with the shift positions in the pitch / yaw directions calculated by the pitch and yaw vibration isolation calculation units 121a and 121b. This performs vibration isolation operation to correct image blur.

[0027] The camera 10 has a shutter unit 151 consisting of a mechanical focal plane shutter (not shown) and a shutter driving section 152 that drives the shutter unit 151. In addition, the system control section 115 controls the shutter unit 151 via the shutter driving section 152 in response to an image capture instruction operation by the release button 16. As a result, an optical image formed by the interchangeable lens 12 is exposed to the image sensor 126, which then performs photoelectric conversion and outputs the image capture signal. The image processing section 131 performs various image processes on the image capture signal to generate an image signal, which is then stored in a storage section 132 such as an SD card. The display section 22 displays the image signal (through image) output from the image processing section 131, and plays back and displays the captured image recorded in the storage section 132.

[0028] When the system control unit 115 detects the operation of the release button 16, the vibration device driving unit 134 outputs a driving signal to the vibration device 100, causing the vibration device 100 to vibrate. In addition, even if the release button 16 is not operated, the vibration device 100 may be made to vibrate when an error occurs during shooting due to the operation of the operation unit 40 as another operating means. In this way, the vibration device 100 applies vibration to the release button 16 shown in FIG. 1, so that when the user touches the release button 16 or operates the release button 16, the user can obtain information from the camera 10 through the vibration.

[0029] 4 shows a perspective view of camera 10 with top cover unit 13 disassembled. Camera 10 is mainly composed of exterior parts: front cover unit 11 forming the front side, rear cover unit 20 forming the rear side, and top cover unit 13 forming the top side. Top cover unit 13 is mainly composed of top cover 201.

[0030] Top cover 201 has power button 14 and mode dial 15 shown in Fig. 1, and release button 16 to be pressed when taking a picture shown in Fig. 4. Release button 16 has a pusher part 16a protruding from the inside.

[0031] A vibration transmission member 202 is provided on the inner surface side of the release button 16 of the top cover unit 13, and one end of the vibration transmission member 202 is fixed to the top cover unit 13 with a screw 205 described later. The vibration transmission member 202 is formed of a metal plate having springiness (elasticity) such as SUS or copper. The vibration device 100 is fixed to a part of the vibration transmission member 202 with an adhesive. The vibration device 100 is formed of a piezoelectric actuator (piezo) using a piezoelectric element. The vibration device 100 is electrically connected to a flexible circuit board by a cable (not shown) or the like, and vibrates by electric power. When the vibration device 100 vibrates, the vibration transmission member 202 to which the vibration device 100 is fixed vibrates. Since the vibration transmission member 202 is formed of a metal with a small loss coefficient of vibration as described above, the vibration generated in the vibration device 100 is transmitted to the entire vibration transmission member 202 with little loss. In this embodiment, a piezoelectric actuator using a piezoelectric element is used as the vibration device 100 for the purpose of saving space, but this is not limited thereto, and an LRA type vibration device may be fixed with double-sided tape, etc. A part of the vibration transmission member 202 engages (abuts) with the pusher portion 16a of the release button 16.

[0032] Near the tip of the pusher portion 16a, ahead of the release button 16 in the pressing direction, there is provided a release switch (photographing means) 300 mounted on a flexible substrate (not shown). In this embodiment, a tactile switch type is used as the release switch 300, and the release switch 300 is electrically connected to a flexible substrate (not shown). When the release switch 300 is turned ON, the camera 10 executes a photographing operation. The release switch 300 has a half-pressed state for determining autofocus and exposure when photographing with the camera 10, and a fully-pressed state for recording an image in the determined state.

[0033] The release switch 300 is attached to a holder 203, and the holder 203 is fixed to the top cover 201 with screws (not shown).

[0034] The vibration device 100 is fixed to the surface of the vibration transmission member 202 on the release switch 300 side. This allows the vibration device 100 to be placed at a position facing the flexible substrate on which the release switch 300 is mounted, without any components being interposed therebetween. This allows for a simple configuration in which the flexible substrate for energizing the vibration device 100 is the same as the flexible substrate on which the release switch 300 is mounted. In other words, the vibration device 100 is electrically connected to the same substrate as the flexible substrate (not shown) on which the release switch 300 is mounted. A weight (weight member) 204 is fixed to the tip portion of the vibration transmission member 202 on the opposite side to the end fixed by the screw 205 with an adhesive or double-sided tape. The weight 204 is preferably made of a material with a high specific gravity, such as tungsten, gold, or lead. The vibration device 100 and the weight 204 are provided on the same surface of the vibration transmission member 202. The surface fixed by the screw 205 is the same as the surface on which the vibration transmission member 202 elastically deforms.

[0035] Next, the vibration device 100, the vibration transmission member 202, the weight 204, and the release button 16 will be described with reference to the schematic cross-sectional view of the release button 106 and its periphery in Fig. 5. First, the configurations of the release button 16, the release switch 300, and the vibration transmission member 202 will be described.

[0036] The release button 16 is held firmly in the top cover 201 by fitting a top cover engagement portion 201a of the top cover 201 into the middle of the pusher portion 16a of the release button 16. The release button 16 is provided with a claw portion or an E-ring (not shown) that engages with the top cover 201 to prevent it from falling off. The pusher portion 16a of the release button 16 and the vibration transmission member 202 to which the vibration device 100 is fixed are engaged with a pusher engagement portion (engagement portion) 202a provided on the vibration transmission member 202 near the tip of the pusher portion 16a. The vibration transmission member 202 has spring properties (elasticity) and generates a force that urges the release button 16 in the opposite direction to the pressing direction of the release button 16. As a result, the presser portion 16a of the release button 16 engages with the vibration transmission member 202 through the presser engagement portion 202a of the vibration transmission member 202, so that the release button 16 is always biased in the direction opposite to the direction in which it is pressed. Furthermore, even if the user presses the release button 16 when operating it, the release button 16 returns to a predetermined position due to the biasing force of the vibration transmission member 202. A release switch 300 is provided at the tip of the presser portion 16a of the release button 16. Therefore, when the user presses the release button 16, the tip of the presser portion 16a comes into contact with the release switch 300, and when the release button 16 is pressed further, the release switch 300 is turned on.

[0037] The release switch 300 is capable of detecting a two-stage pressing operation, and is configured to sequentially turn on a first switch (SW1) and a second switch (SW2) according to the pressing amount. When the release button 16 shown in FIG. 5 is pressed in the thrust direction of the release button 16, the vibration transmission member 202 elastically deforms to press the release switch 300, and the first switch (SW1) turns on. When the first switch (SW1) turns on, the focus drive unit 125 drives the focus unit 124 to adjust the focus. Furthermore, the aperture drive unit 123 drives the aperture unit 122 to perform automatic exposure adjustment (AE), and the system control unit 115 performs shooting preparation such as automatic white balance (AWB) and EF (flash pre-emission) processing. Then, when the release button 16 is pressed further, the second switch (S2) turns on. When the second switch (SW2) is turned on, the shutter driver 152 drives the shutter unit 151, and the optical image formed by the interchangeable lens 12 is exposed onto the imaging element 126.

[0038] Next, the effect of vibrating the vibration device 100 will be described.

[0039] Since the vibration device 100 is fixed to the vibration transmission member 202, the vibration generated in the vibration device 100 vibrates the entire vibration transmission member 202, which is made of a metal material with little vibration transmission loss. The vibration transmission member 202 is fixed to the top cover 201 by a screw 205 at a screw fixing part (fixing part) 202b provided at one end of the vibration transmission member 202. Furthermore, a weight 204 is provided at the tip of the vibration transmission member 202 opposite to the screw fixing part 202b. The vibration device 100 and the weight 204 are arranged on the same plane, and are also arranged on the same plane as the screw fastening surface fixed by the screw 205. With this configuration, the vibration transmission member 202 is in a cantilever state, with one end fixed by a screw and the weight 204 provided at the other end. The vibration device 100 is disposed between the screw fixing portion 202b and the weight 204, and a pusher engagement portion 202a that engages the pusher portion 16a of the release button 16 and the vibration transmission member 202 is disposed near the weight 204. As a result, when the vibration device 100 is vibrated, the vibration transmission member 202 supported at one end vibrates greatly in the weight 204 according to the principle of a pendulum with the screw fixing portion 202b as a fulcrum. That is, the vibration generated in the vibration device 100 is amplified by the weight 204, and the vibration transmission member 202 vibrates. Furthermore, since the vibration transmission member 202 provided with the vibration device 100 is engaged with the release button 16 by the pusher engagement portion 202a, the vibration generated in the vibration device 100 is transmitted to the release button 16 in an amplified state.

[0040] By arranging the pusher engagement portion 202a, which engages the release button 16 and the vibration transmission member 202, near the weight 204 arranged near the tip of the vibration transmission member 202, more amplified vibration is transmitted to the release button 16. At this time, the pusher portion 16a and the pusher engagement portion 202a are arranged in a position where they do not contact the weight 204. The release button 16, which is touched by a finger that attenuates vibration, does not directly contact the weight 204, thereby preventing the suppression of vibration. The weight 204 is heavier than the vibration device 100. Therefore, even if the vibration transmission member 202 bends at the part to which the vibration device 100 is fixed due to the weight of the vibration device 100, the vibration transmission member 202 swings due to the weight 204, and the vibration of the vibration transmission member 202 is reliably amplified.

[0041] Therefore, with a small, inexpensive configuration in which the number of laminated layers of piezoelectric elements is reduced, it is possible to transmit the vibration of the vibration device 100 transmitted to the release button 106 in a sufficiently large vibration that the user can perceive.

[0042] The vibration transmission member 202 is firmly fixed to the top cover 201 with a screw 205. Therefore, the vibration is also transmitted to the top cover 201 via the vibration transmission member 202. Furthermore, since the top cover 201 abuts against the front cover unit 11 and the rear cover unit 20, the top cover 201, the front cover unit 11, and the rear cover unit 20 also vibrate when the vibration device 100 vibrates. Therefore, it is possible for the entire camera 10 to vibrate. In a situation where it is difficult for a user to perceive the vibration of only the release button 16, such as when taking a picture while moving, it is also possible to vibrate the vibration device 100 more strongly so that the vibration can be perceived by the entire hand holding the camera 10 via the entire camera 10.

[0043] In this embodiment, the release switch 300 is a tactile switch having a two-stage switch, but this is not limiting, and it may be one that detects contact resistance using a leaf spring.

[0044] In this embodiment, the vibration device 100 and the weight 204 are disposed on the surface of the vibration transmission member 202 on the release switch 300 side, but this is not limited thereto, and they may be disposed on the surface on the release button 16 side.

[0045] In this embodiment, a part of the pusher portion 16a of the release button 16 engages with the vibration transmission member 202 via the pusher engagement portion 202a, and the release button 16 directly operates the release switch 300. However, without being limited to this, the vibration transmission member 202 may be disposed between the tip of the pusher portion 16a and the release switch 300, and the release switch 300 may be pressed and operated with a part of the vibration transmission member 202. EXAMPLES

[0046] Next, the configuration around the release button 16 of the camera 10 according to the second embodiment will be described with reference to FIG.

[0047] In the first embodiment, the vibration device 100 and the weight 204 are configured to be on the same plane and to be disposed on the same plane as the screw fastening surface. This saves space in the vibration transmission member 202 and makes it easy to process. However, a part of the vibration transmission member 202 may be bent to form a bent portion (non-flexible portion) 202c on a surface different from the screw fastening surface and on a location different from the surface on which the vibration transmission member 202 elastically deforms, and the vibration device 100 may be disposed on the bent portion 202c. The bent portion 202c is a portion of the vibration transmission member 202 that is less likely to elastically deform in the pressing direction of the release button 16 compared to other portions of the vibration transmission member 202 that elastically deform in that direction.

[0048] In the first embodiment, the vibration device 100 is configured using a piezoelectric element, but the piezoelectric element has a multi-layered structure of ceramic. For this reason, the piezoelectric element is weak against deformation, and if the piezoelectric element is fixed to a surface where the vibration transmission member 202 elastically deforms, there is a concern that it will deform together with the vibration transmission member 202 and be destroyed. In addition, even if the vibration device 100 is fixed with a double-sided tape or the like using an LRA, there is a concern that the fixed portion of the double-sided tape or the like will peel off if elastic deformation is repeated due to many vibrations. For this reason, in the second embodiment, a bending process is performed on a part of the vibration transmission member 202 to provide a bending portion 202c that is a portion that is difficult to elastically deform, and the vibration device 100 is fixed to the bending portion 202c. This results in a configuration in which the vibration device 100 does not deform and there is no concern that the vibration device 100 will be destroyed or peeled off.

[0049] Although the preferred embodiments and examples of the present invention have been described above, the present invention is not limited to these embodiments and examples, and various combinations, modifications, and changes are possible within the scope of the gist of the present invention.
