Description

[Technical field]

[0001] The present invention relates to an electronic device having an electronic module that is detachable from the main body of the electronic device. [Background technology]

[0002] In recent years, in electronic devices equipped with functional parts such as input members, a configuration has been known in which the functional parts are modularized and made detachable from the electronic device main body, allowing customization of the position and type according to the user's preferences. For example, the functional parts are detachably attached to the electronic device main body by utilizing the magnetic force of a magnet. Patent Document 1 discloses a structure for attaching and detaching an accessory to an electronic device main body, in which an engagement part inserted into an attachment / detachment opening is slid to engage the projections and recesses of the engagement part, and the attachment part is attracted by the magnetic force of the magnet in the engaged state. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5852182 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in a configuration in which the replacement module slides in one direction and is attracted and held by a magnet as in Patent Document 1, if the electronic device body is dropped and the direction of the impact is substantially opposite to the sliding direction, the replacement module may fall off. If the replacement module of an imaging device such as a camera that is primarily used while being carried around falls off due to a drop or other impact, there is a risk that the replacement module itself will be lost, and therefore a configuration that is less likely to come off due to a drop or other such event is required.

[0005] Furthermore, when the replacement module is small or a rotationally operated module, the exterior portion of the replacement module is composed almost entirely of the operation portion, making it difficult to provide a grip portion for performing attachment and detachment operations.

[0006] The present invention provides an electronic device that includes an electronic module that is easily attachable to and detachable from the electronic device body and that is not easily dislodged by impact. [Means for solving the problem]

[0007] An electronic device according to one aspect of the present invention has an electronic device main body and an electronic module that is detachable from the electronic device main body and electrically connected to the electronic device main body, the electronic module having a protrusion extending radially outward from its outer circumferential surface and a first magnetic body arranged at its bottom, the electronic device main body having a mounting portion which is a cylindrical recess into which the electronic module can be attached, a guide groove formed on the inner circumferential surface of the mounting portion along a first direction in which the electronic module is attached to the electronic device main body and through which the protrusion passes when the electronic module is attached to the electronic device main body, an engagement groove which communicates with the guide groove and is formed along a second direction around an axis parallel to the first direction, and a second magnetic body arranged at the bottom of the mounting portion, the electronic module being inserted into the electronic device main body along the first direction and the protrusion passing through the guide groove, the first magnetic body and the second magnetic body being in different positions in the second direction, and after the electronic module reaches the bottom of the mounting portion and rotates in the second direction due to the adhesive force between the first magnetic body and the second magnetic body, the protrusion engages with the engagement groove. Effect of the Invention

[0008] According to the present invention, it is possible to provide an electronic device that includes an electronic module that is easily detachable from the electronic device body and is not easily dislodged due to impact. [Brief description of the drawings]

[0019] A media cover 26 is provided on the right side of the rear face of the camera 10, and by opening and closing the media cover 26, recording media (not shown) can be inserted into and removed from a slot that stores the recording media.

[0020] A lens mount 28 and a lens lock release button 27 are provided on the front side of the camera 10. The lens mount 28 is a portion for attaching a removable lens (not shown) to the camera 10. When a lens is attached to the camera 10, a lens lock (not shown) functions. The lens lock mechanism is released by pressing the lens lock release button 27, making it possible to remove the lens. A communication terminal 29 is provided inside the lens mount 28, and is used for communication between the camera 10 and the lens.

[0021] 2 is a block diagram of camera 10. An interchangeable lens 70 capable of communicating with a control unit within camera 10 via communication terminal 29 is attached to camera 10. Interchangeable lens 70 includes an imaging optical system 74 made up of a plurality of lens groups and aperture blades, a lens system control unit 72, and a lens driving unit 73. Lens system control unit 72 controls the entire interchangeable lens 70, and lens driving unit 73 performs drive control of the focus lens, zoom lens, aperture, etc.

[0022] The camera 10 includes a camera system control unit 81 and an image sensor 90. The camera system control unit 81 supervises the control of the camera 10 and the interchangeable lens 70. The camera system control unit 81 includes a CPU (Central Processing Unit), and the CPU executes a predetermined program to perform various processes in the imaging system including the camera 10 and the interchangeable lens 70.

[0023] Light that enters the interchangeable lens 70 from a subject is incident on the imaging surface of the imaging element 90 via the imaging optical system 74. A focus evaluation amount and an exposure amount are obtained from an output signal from the imaging element 90, and optical adjustment processing of the imaging optical system 74 is performed based on this information. That is, the imaging element 90 is appropriately exposed, and an imaging signal corresponding to the subject image is output from the imaging element 90.

[0024] A shutter mechanism 89 is provided between the image sensor 90 and the imaging optical system 74. The shutter mechanism 89 includes a light blocking member (mechanical rear curtain) (not shown), and the completion of exposure to the image sensor 90 is performed by the shutter mechanism 89. In the image sensor 90, electronic front curtain processing is performed to control the timing of exposure start by resetting the charge for each line prior to the rear curtain travel of the shutter mechanism 89. In the electronic front curtain mode, exposure control is performed by synchronizing the charge reset operation of the image sensor 90 with the movement of the rear curtain of the shutter mechanism 89.

[0025] The image processing unit 83 includes an A / D converter, a white balance adjustment circuit, a gamma correction circuit, an interpolation calculation circuit, and the like. For example, the image processing unit 83 performs color interpolation (demosaic) processing on the Bayer array signal acquired from the imaging element 90 to generate color image data, and outputs the image data for recording to the storage unit 84. The image processing unit 83 also compresses still images and moving images. The audio control unit 82 compresses audio data to be recorded. The audio data compressed by the audio control unit 82 is synthesized into moving images and still images by the image processing unit 83, and then output to the storage unit 84. The storage unit 84 includes a non-volatile memory, and stores various data including image data. The camera system control unit 81 performs processing for storing data in the storage unit 84, and processing for outputting data read from the storage unit 84 to the display unit 85 to present the data to the user. The display unit 85 corresponds to the display unit 20 and the electronic viewfinder 22.

[0026] The camera system control unit 81 controls imaging processing, image processing, recording and playback processing, etc., in response to a user operation signal. For example, the operation detection unit 86 detects pressing of the shutter release button. A first switch is turned on by half-pressing the shutter release button. A second switch is turned on by fully pressing the shutter release button. When the camera system control unit 81 receives a shooting instruction by operating the second switch from the operation detection unit 86, it performs drive control of the image sensor 90, image processing, compression processing, etc., and further controls display of image information, etc. on the screen of the display unit 20. In addition, the operation detection unit 86 detects an operation of the touch panel 201, for example, and transmits the user's operation instruction to the camera system control unit 81.

[0027] The camera system control unit 81 is connected to the image processing unit 83, and calculates an appropriate focal position and aperture value based on a signal from the image sensor 90. That is, the camera system control unit 81 performs photometry and focus state detection based on the output signal from the image sensor 90, and determines exposure conditions (F-number, shutter speed, etc.). The camera system control unit 81 also performs exposure control of the image sensor 90 by aperture control and shutter control. Furthermore, the camera system control unit 81 transmits a command signal to the lens system control unit 72 via the communication terminal 29. The lens system control unit 72 controls the lens driving unit 73 according to the command signal from the camera system control unit 81.

[0028] The camera system control unit 81 calculates a target value based on a detection signal from the shake detection unit 87, and controls the drive of the shake correction unit 88. In other words, the camera system control unit 81 is responsible for generating the target value based on the detection signal from the shake detection unit 87 and for controlling the drive of the shake correction unit 88. At that time, the camera system control unit 81 controls the image shake correction operation according to the shooting conditions, exposure conditions, etc.

[0029] The shake detection unit 87 can detect rotation about the optical axis, and detects rotational shake of the camera 10 in the pitch, yaw, and roll directions. For example, shake detection is performed using a gyro sensor, and a shake detection signal is output to the camera system control unit 81.

[0030] To briefly explain the flow of drive control of the shake correction unit 88, when the user operates a first switch and the operation detection unit 86 detects the first switch operation, a shooting preparation operation is started. In order to facilitate the user's composition during the so-called aiming operation for determining the composition, the shake correction unit 88 performs image blur correction. That is, the image sensor 90 is driven (moved or rotated) by the control of the shake correction unit 88 based on the detection signal of the shake detection unit 87. After that, the user operates a second switch, and when the operation detection unit 86 detects the second switch operation, a shooting operation (image recording operation) is started. At this time, in order to suppress image blur of the subject image acquired by the exposure operation, the image sensor 90 is driven by the control of the shake correction unit 88 based on the detection signal of the shake detection unit 87. When a certain time has passed after the exposure, the image blur correction operation is stopped.

[0031] An electronic module 40 is detachably attached to the camera 10. The camera 10 communicates with the electronic module 40 via a communication terminal (electrode section) 79. The electronic module 40 includes an operation detection section 48, and controls the camera 10 in accordance with an operation signal detected by the operation detection section 48.

[0032] 1 is attached as the electronic module 40, it can be changed to various operation members according to the user's preference such as an exposure change dial or a sub electronic dial. Depending on the type of the attached operation member, it can be changed to a mode switching function, an exposure change function, a setting information change function, etc.

[0033] In specific operation, when electronic module 40 is attached to camera 10, type information 49 assigned to each type of electronic module 40 is transmitted to camera system control unit 81 via communication terminal 79. Camera system control unit 81 determines the type of attached electronic module 40. A signal output from operation detection unit 48 is converted via signal switching unit 80 and input to a predetermined terminal of camera system control unit 81.

[0034] The electronic module 40 of this embodiment will be described below. Fig. 3 is a perspective view of the electronic module 40. Fig. 3(a) and Fig. 3(b) are a top perspective view and a bottom perspective view, respectively. The electronic module 40 includes a dial section 41 that is rotated by a user, a module base section 42 that includes a bearing section for the dial section 41, and a module cover section 44 that includes a contact section 462 for communicating with the camera 10. A pair of first magnetic bodies 451, 452 are provided at the bottom of the module cover section 44 to attract a magnetic body installed on the camera 10 and fix the electronic module 40 to the camera 10.

[0035] FIG. 4 is a cross-sectional view of the electronic module 40. FIG. 5 shows an exploded perspective view of the electronic module 40. The shaft portion 411 of the dial portion 41 is rotatably held by sliding engagement with the bearing portion 421 of the module base portion 42. A click plate 431 and a contact brush 432 are fixed to the tip of the shaft portion 411 by a fixing screw 435. A wavy uneven portion 431a having an uneven shape formed at a constant phase pitch is provided on the surface of the click plate 431 on the side of the module base portion 42. A non-through circular hole 422 is formed in the module base portion 42, and a click spring 433 and a click ball 434 are assembled in the circular hole 422. In this embodiment, in order to minimize the inclination of the click plate 431, two circular holes 422 are provided at positions that are approximately opposite each other across the center of the bearing portion 421. The click ball 434 is constantly biased against the wavy uneven portion 431 a by the spring pressure of the click spring 433 .

[0036] When the user rotates the operation unit 410 of the dial unit 41, the click plate 431 also rotates integrally, and the two click balls 434 contact the concave and convex parts of the wavy uneven part 431a at the same time, generating a click force. In addition, a circuit board 46 is disposed at a position facing the contact brush 432 in the rotation axis direction. A dial pattern 461 is formed on the contact surface of the circuit board 46 with the contact brush 432, and the circuit board 46 detects the rotation position of the dial unit 41 based on a combination of contact states with the contact parts of the contact brush 432. A contact part 462 for electrically connecting to the camera 10 is provided on the bottom surface of the circuit board 46. In this embodiment, the contact parts 462 are provided at a plurality of locations at predetermined intervals around the circumference. In this embodiment, the case of a mode switching dial 15 for changing the shooting mode is described as an example of the electronic module 40, and the shooting mode can be changed with each click operation.

[0037] The circuit board 46 is fixed to the module cover part 44 with an adhesive or adhesive tape (not shown), and is integrated with the electronic module 40 by assembling the module cover part 44 to the module base part 42. The module cover part 44 is fixed to the module base part 42 with an adhesive, adhesive tape, or screws (not shown). As described above, the first magnetic bodies 451, 452 are fixed to the bottom part of the module cover part 44 with an adhesive or the like. The first magnetic bodies 451, 452 are provided at positions facing each other across the center of rotation of the electronic module. Note that facing includes not only strictly facing each other, but also substantially facing (approximately facing). In addition, the outer peripheral surface 441 of the module cover part 44 is provided with protrusions 442, 443 extending radially outward.

[0038] 6 is a perspective view of the mounting section 50 provided on the camera 10. The mounting section 50 is provided so that the electronic module 40 can be attached to the top cover 18 of the camera 10. The inside of the mounting section 50 is formed in a cylindrical shape since the electronic module 40 is attached by being rotated after being inserted into the mounting section 50. A step section 501 is provided on the inner peripheral surface of the mounting section 50, and a seal member 509 is provided on the step section 501, which is partially crushed when the electronic module 40 is attached to fill and seal the gap between the electronic module 40 and the mounting section 50.

[0039] The inner peripheral surface at the back of the step portion 501 is an engagement surface 502. The engagement surface 502 is formed with guide grooves 503a, 503b extending along the insertion direction of the electronic module 40, and engagement grooves 504a, 504b communicating with the guide grooves 503a, 503b and extending along a rotation direction (second direction) around an axis parallel to the insertion direction. A pair of second magnetic bodies 506, 507 and a communication terminal 79 are provided on the bottom of the mounting portion 50. The second magnetic bodies 506, 507 are provided at positions facing each other across the rotation center of the electronic module. Note that facing includes not only a case where they are strictly facing each other, but also a case where they are substantially facing each other (approximately facing each other). The second magnetic bodies 506, 507 are provided so as to face each other with the first magnetic bodies 451, 452 provided on the electronic module 40, respectively. With this arrangement, when the electronic module 40 is attached, the corresponding magnetic bodies are attracted to each other by magnetic force, and the electronic module 40 is held in the mounting portion 50. The communication terminal 79 includes a plurality of terminals arranged in a circumferential pattern.

[0040] FIG. 7 is a cross-sectional view of the electronic module 40 attached to the camera 10. As described above, the electronic module 40 is attached to the mounting portion 50 of the camera 10. In the state of FIG. 7, as also shown in FIG. 1, only the dial portion 41 is exposed to the exterior of the camera 10, and other portions such as the module base portion 42 and the module cover portion 44 are disposed inside the camera 10. At this time, the first magnetic bodies 451, 452 are attracted to the second magnetic bodies 506, 507, and the electronic module 40 is held immovably within the mounting portion 50. It is preferable that the first magnetic bodies 451, 452 and the second magnetic bodies 506, 507 are made of permanent magnets. This is preferable because it has high positioning property and is unlikely to be displaced. In addition, the protrusions 442, 443 are engaged with the engagement grooves 504a, 504b on the mounting portion 50 side, respectively. This prevents the electronic module 40 from coming off in the removal direction (third direction) E.

[0041] The communication terminal 79 is configured to be extendable and contractible, and is in contact with the contact portion 462 while being charged with a predetermined contact pressure. The communication terminal 79 is electrically connected to a communication board 76 installed further inside the camera 10 than the mounting portion 50, and a signal and type information 49 from the operation detection portion 48 of the electronic module 40 are sent to the camera system control portion 81 via the communication terminal 79 and the communication board 76. The communication board 76 is fixed to the mounting portion 50 or the top cover 18 by fixing means such as fixing screws 77.

[0042] The sealing member 509 contacts the module cover part 44 while being circumferentially charged, and prevents dust, water droplets, etc. from entering the inside of the module cover part 44. The sealing member 509 is preferably disposed on the outside of electrical contact parts such as the communication terminal 79 and the contact part 462, and more preferably disposed in a position close to the exterior side.

[0043] Fig. 8 is a schematic diagram showing an example of a method for attaching the electronic module 40 of this embodiment. Fig. 8(a) is a schematic diagram showing the start of attachment, Fig. 8(b) is a schematic diagram showing attachment in the middle, and Fig. 8(c) is a schematic diagram showing attachment completion, in which the left side diagrams in each diagram are schematic diagrams seen from the side, and the right side diagrams are schematic diagrams seen from the insertion direction.

[0044] When the electronic module 40 is mounted on the mounting section 50, as shown in FIG. 8(a), the electronic module 40 is inserted along the insertion direction (first direction) S while the protrusions 442, 443 of the electronic module 40 and the guide grooves 503a, 503b of the mounting section 50 are aligned. In this embodiment, the protrusions 442, 443 are disposed at substantially opposing positions to provide a well-balanced function of preventing the electronic module 40 from coming off. In addition, in order to prevent the electronic module 40 from being misassembled in the wrong phase, it is preferable that the protrusions 442, 443 are not positioned completely opposite each other, but are disposed with a slight phase shift, or that the sizes of the two protrusions are made different. In this embodiment, an example in which the protrusion 443 is shifted in phase by about 10 degrees from the opposing position of the protrusion 442 will be described. The guide grooves 503a, 503b are shaped to be engageable only in the correct phase according to the positions and sizes of the protrusions 442, 443.

[0045] In this embodiment, the case where two protrusions are provided will be described, but the number of protrusions is not limited to this. When three or more protrusions are provided, it is preferable to arrange them at approximately equal positions in the circumferential direction.

[0046] When the electronic module 40 is pushed in the insertion direction S in the state of FIG. 8(a), the protrusions 442 and 443 pass through the guide grooves 503a and 503b, respectively, and the electronic module 40 hits the back of the mounting section 50 as shown in FIG. 8(b). At this time, the protrusions 442 and 443 move to the back of the guide grooves 503a and 503b, respectively, and the first magnetic bodies 451 and 452 are positioned at positions shifted by the same phase in the rotation direction as the second magnetic bodies 506 and 507, respectively. Here, the first magnetic body 451 and the second magnetic body 506 are arranged in a direction in which they attract each other, and are close enough to generate an attractive force. The same is true for the first magnetic body 452 and the second magnetic body 507. Therefore, the corresponding magnetic bodies are attracted to each other by the magnetic force, and the electronic module 40 rotates in the CCW direction in the right-hand diagram.

[0047] Furthermore, while the electronic module 40 is being pushed in the insertion direction S, the communication terminal 79 comes into contact with the circuit board 46 and begins to charge, but at this point the communication terminal 79 and the contact portion 462 are in misaligned positions and are not yet communicating electrically.

[0048] When the electronic module 40 finishes rotating, it reaches the mounting completion position as shown in FIG. 8(c). At this time, the first magnetic body 451 and the second magnetic body 506, and the first magnetic body 452 and the second magnetic body 507 are in an adsorbed state, and the electronic module 40 is held so as not to move. Furthermore, the protrusions 442 and 443 engage with the engagement grooves 504a and 504b, respectively, due to the rotational movement of the electronic module 40, so that the electronic module 40 is locked in the removal direction E. Here, if the camera 10 is dropped carelessly, the direction of the drop impact is along the direction of gravity, and no rotational force is generated to rotate the electronic module 40 around the rotation axis. Therefore, in this embodiment, even if an impact such as a drop is applied, the electronic module 40 is unlikely to rotate in the removal direction and is locked in the removal direction, so that it is possible to prevent the electronic module 40 from being easily removed.

[0049] 8(c), the communication terminal 79 and the contact portion 462 come into contact, and the electronic module 40 and the camera 10 are electrically connected, enabling communication. When communication starts, the type information 49 is transmitted to the camera system control portion 81, and the camera system control portion 81 identifies the type of the electronic module 40 attached to the camera 10. When the type of the electronic module 40 is identified, input operations of the electronic module 40 attached to the camera 10 become possible.

[0050] 9A and 9B are schematic diagrams showing an example of a method for removing the electronic module 40 of this embodiment. Fig. 9(a) shows the attached state, and Fig. 9(b) shows the removable state.

[0051] In this embodiment, an example is described in which the electronic module 40 that can be attached to the camera 10 has a rotatable dial shape, and only the dial operation part is exposed to the exterior. When it is desired to remove the electronic module 40, it is necessary to rotate the protrusions 442, 443 to a position where the electronic module 40 can be removed along the removal direction E. However, in this embodiment, the only part that can be operated by the user is the dial part 41, and even if the dial part 41 is turned, only the dial part 41 turns, so a configuration for rotating the protrusions 442, 443 is required.

[0052] As an example of the above configuration, an example in which a tool is used will be described. A method of directly rotating electronic module 40 with tool 60 and moving it to a position where it can be removed will be described below. A tool hole (hole portion) 191 is provided near a portion of rear cover 19, which is an exterior member on the rear side of camera 10, where electronic module 40 is attached. Tool 60 can be inserted into tool hole 191.

[0053] As shown in FIG. 9(a), the tool hole 191 is connected to the protrusion 442 of the electronic module 40 attached to the camera 10, and the protrusion 442 can be directly pushed by inserting the tool 60 into the tool hole 191. As shown in FIG. 9(b), after the tool 60 contacts the protrusion 442, the tool 60 is pushed in until the protrusions 442, 443 rotate from the engagement grooves 504a, 504b to the position of the guide grooves 503a, 503b. When the protrusion 442 rotates to the above position, the engagement between the protrusions 442, 443 and the engagement grooves 504a, 504b is released, and the electronic module 40 can be moved in the removal direction E. Furthermore, the first magnetic bodies 451, 452 and the second magnetic bodies 506, 507 are out of phase with each other, and the adhesive force is weakened, making it easier to remove the electronic module 40, and the user can remove the electronic module 40 from the mounting part 50 by pulling the electronic module 40 in the removal direction E. [Second embodiment] In this embodiment, a method for removing the electronic module 40 that is different from that described in the first embodiment will be described. In this embodiment, the positions of the second magnetic bodies 506, 507 on the mounting unit 50 side are movable, and by rotating the second magnetic bodies 506, 507, the electronic module 40 is rotated in conjunction with the second magnetic bodies 506, 507 and moved to a position where it can be removed. Note that other configurations are the same as in the first embodiment, and therefore description thereof will be omitted.

[0054] Fig. 10 is a schematic diagram showing an example of a method for removing the electronic module 40 of this embodiment. Fig. 10(a) shows the attached state, Fig. 10(b) shows the removable state, and Fig. 10(c) shows the removed state. In each figure, the left side shows a schematic diagram seen from the side, and the right side shows a schematic diagram seen from below.

[0055] The second magnetic bodies 506, 507 are fixed to the bottom of the mounting section 50 in the first embodiment, but in this embodiment, they are held by a magnetic body holder (rotating section) 511 rotatably attached to the mounting section 50. The magnetic body holder 511 is attached to the bottom of the mounting section 50 by fixing means 513. Also, as shown in the right-hand diagram of Fig. 10(a), when the electronic module 40 is attached to the camera 10, the magnetic body holder 511 is pulled in the CW direction in the right-hand diagram by a tension spring 514, and does not move by operating the dial section 41, etc.

[0056] In the state shown in FIG. 10(a), the tool 60 is inserted from the tool hole 191 provided in the rear cover 19, as in the first embodiment. The inserted tool 60 pushes in the rotating lever 512 of the magnetic body holder 511, causing the magnetic body holder 511 to rotate in the CCW direction in the right-hand diagram. At this time, when the second magnetic bodies 506, 507 rotate together with the magnetic body holder 511, the second magnetic bodies 506, 507 and the first magnetic bodies 451, 452 are attracted to each other, so that the electronic module 40 also rotates together with the magnetic body holder 511. In this embodiment, inclined grooves 505a, 505b are formed between the guide grooves 503a, 503b and the engagement grooves 504a, 504b, through which the protrusions 442, 443 can pass and which are inclined with respect to the removal direction E. Therefore, when the electronic module 40 rotates in conjunction with the magnetic body holder 511, the protrusions 442, 443 move along the inclined grooves 505a, 505b in the direction of arrow R, and the electronic module 40 moves in the removal direction E while rotating together with the magnetic body holder 511.

[0057] 10(b), when the protrusions 442, 443 reach the guide grooves 503a, 503b after climbing up the inclined grooves 505a, 505b, the restriction on the movement of the protrusions 442, 443 in the removal direction E is released, and the electronic module 40 becomes removable. At this time, since the electronic module 40 has moved in the removal direction E away from the mounting part 50, the distance between the first magnetic bodies 451, 452 and the second magnetic bodies 506, 507 increases, and the adhesive force weakens. Even in this state, the user can remove the electronic module 40 by pulling the electronic module 40 in the removal direction E, but the magnetic body holder 511 is configured to be further rotatable by pushing the tool 60 in.

[0058] When the magnetic body holder 511 is further rotated from the removable state, the second magnetic bodies 506, 507 and the first magnetic bodies 451, 452 are out of phase with each other in the rotation direction, as shown in FIG. 10(c). Therefore, the adhesive force between the corresponding magnetic bodies is further weakened than in the removable state. At this time, the communication terminal 79 on the mounting unit 50 side charges the electronic module 40 in the removal direction E with a predetermined contact pressure. Therefore, if the charging force becomes stronger than the adhesive force between the corresponding magnetic bodies, the electronic module 40 is pushed out in the removal direction by the contact pressure of the communication terminal 79, and the user can easily remove the electronic module 40. [Third embodiment] In this embodiment, a method for attaching electronic module 40 to camera 10 and a method for detaching electronic module 40 from camera 10 will be described in a case where a lock mechanism for locking electronic module 40 in the rotation direction while attached to camera 10 is added to electronic module 40. Note that other configurations are the same as those in the first embodiment, and therefore description thereof will be omitted.

[0059] FIG. 11 is a schematic diagram showing an example of a method for attaching the electronic module 40 of this embodiment. FIG. 11(a) is a schematic diagram showing the start of attachment, FIG. 11(b) is a schematic diagram showing attachment during installation, and FIG. 11(c) is a schematic diagram showing attachment completion, with the left-hand diagrams being schematic diagrams seen from the side and the right-hand diagrams being schematic diagrams seen from the insertion direction. FIG. 12 is a schematic diagram showing an example of a method for removing the electronic module 40 of this embodiment. FIG. 12(a) shows the attached state (locked state), FIG. 12(b) shows the removal start state, and FIG. 12(c) shows the removable state. All diagrams are schematic diagrams seen from the insertion direction.

[0060] As shown in the right-hand diagram of Fig. 11(a), a lock lever (lock mechanism) 61 for restricting movement of the electronic module 40 in the rotational direction when the electronic module 40 is attached is provided on the outside of the mounting part 50. Also, a release lever (release mechanism) 62 for moving the electronic module 40 to a removal position in conjunction with the operation of a tool 60 (see Fig. 12) is provided.

[0061] The lock lever 61 is supported rotatably around a lever rotation shaft 612. A lock claw (convex portion) 610 is provided at the tip of the lock lever 61, which protrudes from the inner peripheral surface of the mounting portion 50 and engages with a claw engagement portion (concave portion) 445 provided on the outer peripheral surface 441 of the module cover portion 44 to regulate the rotation of the electronic module 40. The release lever 62 is held so as to be movable only in a certain direction (the direction of the arrow L), is connected to the lock lever 61 by a link portion 613, and operates in conjunction with the movement of the lock lever 61.

[0062] The engagement surface 502 of the mounting portion 50 is provided with a hole (not shown) so that the lock claw 610 protrudes inward from the engagement surface 502 .

[0063] The release lever 62 can be moved from a retracted position to a release position by inserting the tool 60, and is normally installed so as to always be located at the retracted position by a lock spring 63 (a compression spring in this embodiment). At this time, the lock lever 61, which moves in conjunction with the release lever 62 by a link portion 613, is biased in the direction of arrow M so as to be located at a lock position where the lock claw 610 projects inward from the engagement surface 502.

[0064] The operation of attaching the electronic module 40 to the camera 10 will be described below with reference to FIG. 11. Before attaching the electronic module 40 to the camera 10, as shown in the right diagram of FIG. 11(a), the lock lever 61 is biased in the direction of the arrow M by the spring force of the lock spring 63, and the lock claw 610 protrudes inward from the engagement surface 502. When the electronic module 40 is inserted in the insertion direction S with the projections 442, 443 of the electronic module 40 aligned with the guide grooves 503a, 503b of the mounting portion 50, the outer peripheral surface 441 of the module cover portion 44 comes into contact with the lock claw 610. As shown in the left diagram of FIG. 11(a), an inclined surface portion 611 inclined with respect to the insertion direction S is formed on the upstream side of the lock claw 610 in the insertion direction S. As a result, when the electronic module 40 is pushed in along the insertion direction S, the lock claw 610 retreats in the direction of the arrow N as shown in FIG. 11(b).

[0065] When the electronic module 40 is inserted to the position shown in FIG. 11B, the first magnetic bodies 451 and 452 and the second magnetic bodies 506 and 507 are attracted to each other, and the electronic module 40 rotates in the CCW direction in the right-hand view of FIG. 11, as in the first embodiment. Then, as shown in FIG. 11C, the protrusions 442 and 443 engage with the engagement grooves 504a and 504b. When the electronic module 40 rotates to the position shown in FIG. 11C, the claw engagement portion 445 rotates to the position of the lock claw 610, so that the lock lever 61 rotates in the direction of the arrow M, and the lock claw 610 moves to a lock position where it protrudes inward from the engagement surface 502, and engages with the claw engagement portion 445. As a result, in addition to the holding force due to the attraction between the corresponding magnetic bodies, a lock in the rotation direction by the mechanical mechanism is added, so that the rotation of the electronic module 40 can be more firmly restricted.

[0066] Hereinafter, the operation of removing the electronic module 40 from the camera 10 will be described with reference to FIG. 12. In the locked state of FIG. 12(a), the lock claw 610 engages with the claw engagement portion 445, and the rotation of the electronic module 40 is restricted. In the state of FIG. 12(a), the tool 60 is inserted through the tool hole 191 of the rear cover 19. When the tool 60 is further inserted in the direction of the arrow K after contacting the release lever 62, as shown in FIG. 12(b), the lock lever 61 rotates in the direction of the arrow N in conjunction with the movement of the release lever 62, and the engagement between the lock claw 610 and the claw engagement portion 445 is released. When the tool 60 is further inserted in the direction of the arrow K from this point, the release lever 62 pushed in by the tool 60 comes into contact with the protrusion 442, and the electronic module 40 starts to rotate. Here, the release lever 62 and the protrusion 442 are in a relationship in which they start to come into contact only after the engagement between the lock claw 610 and the claw engagement portion 445 is released.

[0067] 12(c), when the electronic module 40 rotates in the CW direction until the protrusion 442 reaches the guide groove 503a, the tool 60 cannot be inserted any further. At this time, the restriction on the electronic module 40 in the insertion direction S is released, so that the user can remove the electronic module 40 from the mounting part 50 by pulling the electronic module 40 in the removal direction E.
