Embodiment 4

Next, Embodiment 4 of the present invention will be described. The module 200 can be attached to and detached from the device body 100 by turning the lock member. FIG. 10 is a perspective view when a state in which the module 200 is attached to the device main body 100 according to the present embodiment is viewed from the front side. FIG. 11 is a perspective view of the state in which the module 200 is removed from the device main body 100 when viewed from the front side. FIG. 12 is an exploded perspective view of the state in which the module 200 is removed from the device main body 100 when viewed from the back side. FIG. 13 is an exploded perspective view of the device main body 100. The device main body 100 is a camera module, and the module 200 is a power supply module having a battery.

The device main body 100 includes an imaging unit 101 exposed on the front surface. The imaging unit 101 includes an optical member such as a lens and a diaphragm that form an imaging optical system, and an imaging element. Hereinafter, the upper surface forming the casing 130 of the device main body 100 is defined as the first surface S1. Of the plurality of side surfaces substantially orthogonal to the front surface of the housing 130, the side surface close to the front surface on which the imaging unit 101 is disposed is the second surface S2, and the side surface of the housing 130 that is different from the second surface S2 is the first surface. 3 plane S3. In addition, the device main body 100 is provided with a connector unit 120 described later on the back surface opposite to the front surface on which the imaging unit 101 is exposed. Therefore, in the device main body 100, the first surface S1 to the third surface S3 described above are different from the front surface and the back surface described above. In the present embodiment, the second surface S2 is a right side when viewed from the front side, and the third surface S3 is a left side when viewed from the front side. A surface S4 formed around the front surface is a tapered surface. The second surface S2 is not adjacent to the third surface S3, and the imaging unit 101 is located in the vicinity of the first surface S1 and the second surface S2. In addition, the imaging part 101 should just be located in the front surface of the apparatus main body 100 at least near the 1st surface S1 (for example, center upper position etc.).

The lock operation unit 141a and the

operation members

151 and 152 are disposed as operation members on the side surface of the casing 130 of the device main body 100. The lock operation unit 141a is a lock lever provided integrally with a lock member 141 described later. The lock operation unit 141a is disposed in the vicinity of the third surface S3 that is not adjacent to (but not adjacent to) at least one of the first surface S1 and the second surface S2. In the present embodiment, since the lock operation unit 141a is disposed in the vicinity (corner) of the first surface S1 and the third surface S3, the lock operation unit 141a is not adjacent to the second surface S2. . As shown in FIG. 10, in a state in which the module 200 is mounted on the device main body 100, the lock operation unit 141a is almost within the projected area when the device main body 100 is viewed from the front side. In the state of FIG. 11 in which the module 200 is released from the device main body 100, the lock operation unit 141a has moved to a position protruding outward from the projection area as indicated by an arrow R.

The operating

members

151 and 152 are disposed on the first surface S1. The operation member 151 close to the lock operation unit 141a is an operation member for outputting an operation signal corresponding to the user's operation, and in this embodiment, is a release button used when the user instructs imaging of the subject. The operation member 152 is an operation member for outputting an operation signal different from that of the operation member 151. The operation member 152 is disposed closer to the imaging unit 101 than the operation member 151, that is, a position closer to the optical axis of the imaging optical system.

In an internal space formed by the casing 130 and the back plate 110 of the device main body 100, a chassis 140, a circuit board unit 150, a heat radiating unit 160, a holding member 170, and a lock member 141 are provided (FIG. 13). The heat generated in the circuit board unit 150 can be diffused to the module 200 side through the heat radiating unit 160.

The module 200 includes a housing that can be connected to the device main body 100 by bayonet coupling. The module 200 has an annular portion 201 on the front surface portion connected to the device main body 100. A plurality of claw portions 201 a are formed in the annular portion 201 in the circumferential direction, and engage with the plurality of claw portions formed on the lock member 141, respectively. The module 200 has a connector part 210 inside the annular part 201. The connector part 210 is electrically connected to a connector part 120 (FIG. 12) provided in the device main body 100. In this embodiment, the connector part 210 of the module 200 is a plug protruding forward, and the connector part 120 of the device main body 100 is a jack.

The plurality of engaging protrusions 230 provided on the front surface portion of the module 200 are engaging pins respectively disposed on the left and right sides of the connector portion 210 outside the annular portion 201. Engagement recesses 123 (FIGS. 12 and 14) respectively corresponding to the plurality of engagement projections 230 are formed on the back surface of the apparatus main body 100, and the engagement projections 230 are engaged with the engagement recesses when the module 200 is mounted. 123 is engaged. The plurality of engaging convex portions 230 have a role of a guide leading when the user attaches the module 200 to the device main body 100 and a role of safely and reliably connecting the connector portion 210. Further, the plurality of engaging convex portions 230 serve to protect the connector portion 210. Since the protruding amount of the engaging convex portion 230 is larger than the protruding amount of the connector portion 210 with reference to the front surface of the module 200, for example, it is possible to avoid the impact due to the dropping of the module 200 or the like from being directly applied to the connector portion 210. Further, in the module 200, concave portions 240 and 250 (FIG. 11) are formed on the contact surface with the device main body 100 so as to be fitted with convex portions provided in another module device (not shown). Since the apparatus main body 100 is not provided with convex portions corresponding to the

concave portions

240 and 250, the other module devices and the apparatus main body 100 can be distinguished on connection. Other module devices will be described later with reference to FIGS.

FIG. 14 is an exploded perspective view in which a part of the device main body 100 is disassembled and shown from the back side. FIG. 15 is an exploded perspective view showing the periphery of the lock member 141 and the heat radiating part 160. A lock member 141 is disposed between the back plate 110 of the device main body 100 and the housing 130. As in the first embodiment, the lock member 141 is formed by integrating a lock operation portion 141a, an annular shape portion 141b, and a plurality of claw portions 141c provided inside the lock operation portion 141a. The claw portion 141c is a bayonet claw. The lock operation portion 141a and the annular shape portion 141b rotate integrally. The lock member 141 moves between a locked position connected to the module 200 by bayonet coupling and an unlocked position (unlocked position) in which the lock with the module 200 is released. As in the case of the first embodiment, the lock member 141 is configured to be held in the locked position or the unlocked position by the metal sphere 121 and its biasing member (elastic member) 122.

FIG. 16 is a cross-sectional view seen from the back side for explaining the lock position and the non-lock position of the lock member 141. FIG. 16A shows the lock member 141 in the locked position, and FIG. 16B shows the lock member 141 in the unlocked position. FIG. 17 is a perspective view showing the engagement relationship between the lock member 141 and the module 200 from the front side. FIG. 17A shows a state in which the lock member 141 is in the locked position, and FIG. 17B shows a state in which the lock member 141 is in the unlocked position. In the camera 100 and the module 200, portions not directly related to the gist of the present invention are not shown.

The lock member 141 is in a state where the plurality of claw portions 141c are respectively engaged with the plurality of claw portions 201a formed in the module 200 at the lock position. At this time, the lock operation unit 141a does not protrude outside the projected area when the device main body 100 is viewed from the front side, and the protruding amount at the locked position is smaller than the exposed amount at the unlocked position. When the user operates the lock operation unit 141a and the lock member 141 rotates counterclockwise in FIG. 16, the engagement between the device main body 100 and the module 200 is released. At this time, the lock operation unit 141a is in a state of protruding out of the projection area when the device main body 100 is viewed from the front side. In other words, the lock operation portion 141 a that is extended and formed on the lock member 141 protrudes from the outer shape of the device main body 100 at the unlocked position of the lock member 141.

FIG. 18 is an exploded perspective view showing a configuration example of the module 200. The module 200 includes a front surface portion 212, a substrate portion 213, a battery portion 216, and a cover member 218. The connector part 210 provided on the board part 213 is exposed to the outside through an opening 212 a formed in the front part 212.

In the present embodiment, the imaging unit 101 is arranged in the vicinity of the first surface S1 and the second surface S2 in the housing 130 of the device main body 100, and the lock operation unit 141a includes the first surface S1 and the third surface. It arrange | positions in the vicinity of S3 (FIG. 10, FIG. 11). For example, even when an attachment is attached to the lens of the imaging unit 101, the user can operate the lock operation unit 141a. The attachment is, for example, a lens hood, a wide-angle attachment that widens the angle of view that can be photographed, a fish-eye attachment that enables fish-eye photography, and the like, and can be attached to the imaging unit 101. The user does not need to perform complicated operations regarding the attachment / detachment between the device main body 100 to which the attachment is attached and the module 200. Further, in application to a small camera module, it is possible to suppress as much as possible damage to the lens and adhesion of fingerprints to the front surface of the lens when the user operates the lock operation unit 141a.

Next, the relationship between the lock operation unit 141a and the operation member 151 will be described with reference to FIGS. The operation member 151 is disposed on the first surface S1 of the device main body 100, and the protruding amount is denoted as L1 (FIG. 10). The operation member 151 of the present embodiment is a release button used by a user for an imaging instruction, and the operation direction P is a push-in direction.

When the protrusion amount of the lock operation portion 141a is expressed as L2, the protrusion amount from the outer shape of the device main body 100 (hereinafter referred to as L2) is substantially zero at the lock position in FIG. Less than the amount. On the other hand, in the unlocked position in FIG. 16B, the protrusion amount L2 of the lock operation portion 141a is larger than the protrusion amount L1 of the operation member 151 (L2> L1). At this time, when the device main body 100 is viewed from the first surface side (upper side), the lock operation unit 141 a is in a position overlapping the operation member 151. The direction in which the user operates the lock operation unit 141a when performing the unlocking operation is a direction in which the lock operation unit 141a protrudes from the first surface S1.

Suppose, for example, that a release operation is performed in an unlocked state and an imaging operation is performed. In this case, if the connection between the apparatus main body 100 and the module 200 is unexpectedly released, there is a possibility that the captured image cannot be recorded because the power supply is not performed. In the present embodiment, it is possible to prevent an erroneous operation on the device main body 100 in an unlocked state (unlocked state). That is, the operation direction of the lock operation unit 141a when releasing the lock is substantially opposite to the operation direction (push-in direction) of the operation member 151. Even if the user accidentally touches the lock operation unit 141a when the user operates the operation member 151 in the pushing direction, the lock operation unit 141a is not unlocked, which is effective in preventing an erroneous operation. In the unlocked state, the protrusion amount of the lock operation portion 141a is larger than the protrusion amount of the operation member 151 with reference to the first surface S1. For this reason, it is possible to prevent the user from performing a release operation on the operation member 151 in the unlocked state.

In addition, the operation member 152 is located closer to the optical axis of the imaging unit 101 than the operation member 151 on the first surface S1 in the device main body 100. Therefore, when the user operates the operation member 152, there is almost no possibility of erroneous operation due to the finger touching the lock operation unit 141a. Note that the operation member 152 is less frequently operated during photographing than the operation member 151. That is, when it is necessary to arrange the operation member 151 having a higher operation frequency during photographing close to the protruding position of the lock operation unit 141a in the unlocked state, an unintended operation by the user in the unlocked state is input. Can be suppressed.

Next, with reference to FIG. 19, heat transfer from the device main body 100 to the module 200 will be described. FIG. 19A is a longitudinal sectional view showing a state in which the module 200 is mounted on the device main body 100. FIG. 19B is an enlarged view showing a portion B in FIG. FIG. 20 is an enlarged view showing a portion B of FIG. 19A, and is a diagram illustrating a case where the heat conducting member 214 is not provided.

Attachment of the module 200 to the device main body 100 is performed by the first mount portion M1 provided on the back surface portion of the device main body 100 and the second mount portion M2 provided on the front surface portion of the module 200. The first mount portion M1 has a first mount reference surface MS1 formed in the circumferential direction. The second mount portion M2 has a second mount reference surface MS2 formed in the circumferential direction so as to face the first mount reference surface MS1. The second mount reference surface MS2 corresponds to the front end surface of the annular portion 201, and abuts on the first mount reference surface MS1 in the locked state.

The device main body 100 includes a heat radiating member 107 provided inside the first mount portion M1 so as to protrude rearward (module 200 side) from the first mount reference surface MS1. The heat radiating member 107 is a member that radiates the heat generated by the heat source inside the device main body 100, similarly to the heat radiating plate 7 described in the first embodiment.

The claw portion 141c of the lock member 141 protrudes rearward from the first mount reference surface MS1. The module 200 includes a contact surface 201S that can be engaged with the claw portion 141c in a state where the module 200 is mounted on the device main body 100 from the rear side. The contact surface 201S is formed in the annular portion 201 at the second mount portion M2, and is located behind the second mount reference surface MS2. A concave portion 206 is formed inside the second mount portion MS2 in order to reduce interference with the heat radiating member 107. The recess 206 is formed behind the second mount reference surface MS2, and a heat conducting member 214 that transmits heat from, for example, the heat radiating member 107 is disposed in the recess. Since the heat conducting member 214 is the same as the heat conducting member 14 of the first embodiment, detailed description thereof is omitted.

In the present embodiment, the heat dissipating member 107 formed of a metal material or the like can be separated from the housing 130 of the device main body 100 by projecting from the first mount reference surface MS1. Further, the heat radiating member 107 is disposed inside the first mount portion M1 formed in the circumferential direction. Therefore, a sufficient heat radiation area can be secured, and the contact area between the claw portion 141c and the contact surface 201S can be increased to improve the strength. A recess 206 is formed in the module 200, and interference with the heat radiating member 107 can be reduced when the module 200 is attached to the apparatus main body 100. When the heat conducting member 214 is disposed in the recess, the heat conducting member 214 comes into contact with the heat radiating member 107. However, if the heat conducting member 214 and the heat radiating member 107 can be elastically contacted, the member The interference between them can be sufficiently reduced. When the module has a cooling unit, the heat generated in the device main body 100 is stored through the recess 206. In the present embodiment, the contact surface 201S that can be engaged with the claw portion 141c is exemplified as a surface perpendicular to the optical axis direction, but may be a surface having a predetermined angle with respect to the optical axis direction. Further, as illustrated in FIG. 20, when the module 200 is not provided with the heat conducting member 214, the clearance between the heat radiating member 107 and the recess 206 in the state where the module 200 is mounted on the device main body 100. Occurs. Also in this case, the interference by the heat radiating member 107 when the module 200 is attached to the device main body 100 can be reduced by the recess 206.
Here, with reference to FIG. 11, 12, the positional relationship of the thermal radiation member 107, the connector part 120, the engagement recessed part 123, the lock operation part 141a, the connector part 210, and the engagement convex part 230 is demonstrated in detail. On the back surface of the device main body 100, a connector part 120 is disposed below the heat radiating member 107. Therefore, on the front surface of the module 200, the connector portion 210 is disposed above the recess 206 in a state where the module 200 is mounted on the device main body 100. With this configuration, the heat radiating member 107 is located at the normal position (first state) of the apparatus main body 100 where the first surface S1 faces the opposite side to the direction of gravity as shown in FIG. The degree to which the heat diffused from the heat is transmitted to the connector side can be reduced.
Further, on the back surface of the apparatus main body 100, the engagement recess 123 is provided in the vicinity of the connector portion 120 and on the outer side (side closer to the outer shape of the housing 130) than the connector portion 120. And the engagement recessed part 123 is the opposite side to the lock operation part 141a across the connector part 120, and is different from the two corners close to the lock operation part 141a among the four corners on the back surface of the device main body 100. It is provided in the vicinity of the two corners. Therefore, the engagement convex portion 230 is in the vicinity of the connector portion 210 on the front surface of the module 200, and the region of the module 200 that faces the lock operation portion 141 a in a state where the device main body 100 is attached to the module 200 and the connector portion 210. It is provided on the opposite side across. Note that the tangent lines of the two engaging convex portions 230 are in a substantially parallel positional relationship with respect to the longitudinal side of the connector portion 210. With the configuration described above, the external dimensions of the device main body 100 and the module 200 can be reduced as much as possible. Further, for example, in a state where the connector part 210 is exposed to the outside, the probability that the engaging convex part 230 contacts the outside prior to the connector part 210 can be increased, so that the connector part 210 can be protected more effectively. I can do it.

Next, with reference to FIG. 19, the waterproofing and foreign matter intrusion prevention measures will be described.
In the device main body 100, a convex portion 126 is formed inside the first mount portion M1. The convex portion 126 is on the inner side of the first mount reference surface MS1 and protrudes rearward (on the module 200 side) from the first mount reference surface MS1. The convex portion 126 is formed in the circumferential direction so as to surround the connector portion 120. The claw portion 141c formed on the lock member 141, which is a rotating member, is located on the outer peripheral side of the convex portion 126 and extends inward at a position protruding rearward from the first mount reference surface MS1. That is, a part of the claw portion 141c is located at the same position as the first mount reference surface MS1 in the radial direction orthogonal to the optical axis when viewed from the optical axis direction. A part of the claw portion 141c is positioned so as to overlap with the first mount reference surface MS1 in a direction parallel to the optical axis. For this reason, it can prevent that water and a foreign material penetrate | invade between the nail | claw parts which fasten the apparatus main body 100 and the module 200, and can suppress that the engagement relationship of nail | claw parts loosens.

When the module 200 is mounted on the device main body 100, the claw portion 201a of the annular portion 201 and the claw portion 141c of the lock member 141 are engaged. In a state where the second mount reference surface MS2 is in contact with the first mount reference surface MS1, the claw portion 201a is located between the first and second mount reference surfaces and the claw portion 141c. That is, the contact surface 201S is a contact surface with the claw portion 141c in the second mount portion M2.

A relief portion 226 for reducing interference with the convex portion 126 is formed on the inner peripheral side of the second mount portion MS2. The escape portion 226 is a portion recessed rearward from the second mount reference surface MS2. In a state where the module 200 is mounted on the device main body 100, the convex portion 126 enters the escape portion 226. In the present embodiment, the escape portion 226 has a U-shape so as to be fitted to the convex portion 126, but may be any shape that can escape the convex portion 126. For example, the structure which does not provide a part of wall surface in the direction parallel to an optical axis (for example, the wall surface of the inner side of the module 200) among the wall surfaces which form the escape part 226 may be sufficient. Further, as illustrated in FIG. 20, for example, a buffer member 227 having a sealing function may be disposed in the gap between the escape portion 226 and the convex portion 126. If it is this structure, compared with the case where the buffer member 227 is not provided, it can suppress more effectively that water and a foreign material penetrate | invade inside an apparatus.

In this embodiment, a waterproof effect and a foreign matter intrusion preventing effect are achieved by a key-like engagement using the claw portion 141c extending inward by the lock member 141 and the claw portion 201a extending outward by the module 200. Can be increased. The claw portion 141c of the lock member 141 extends inwardly at a position protruding from the first mount reference surface MS1, and at least a part thereof is at the same radial position as the first mount reference surface MS1, The first and second mount reference surfaces are in contact with each other. Furthermore, by forming the convex portion 126 on the inner side of the first mount reference surface MS1, the intrusion of water and foreign matter can be prevented more reliably, and the connector portion 120 of the device main body 100 and the connector portion of the module 200 can be prevented. 210 can be protected. In addition, although the connector part which performs the electrical connection between apparatuses was illustrated in this embodiment, it is not this limitation. The present invention can be applied to electronic devices having various connection members that perform thermal connection or the like.

The engagement relationship between the claw portion 141c of the lock member 141 and the claw portion 201a of the module 200 and the backlash prevention measure will be described with reference to FIGS. FIG. 21A shows a state where the claw portion 141c of the lock member 141 and the claw portion 201a of the annular portion 201 of the module 200 are engaged when viewed from the optical axis direction of the imaging optical system. FIGS. 21B-1 and 21B-2 show the positional relationship when the claw portion 141c is engaged with the claw portion 201a when viewed from the direction orthogonal to the optical axis direction of the imaging optical system. FIG. 21B-1 shows a state where the claw portions are engaged with each other, and FIG. 21B-2 shows a claw portion 201a of the annular portion 201 of the module 200. FIG. 22 illustrates the lock member 141. 22A is a rear view of the device main body 100, and FIG. 22B is a perspective view showing the lock member 141. FIG. In another embodiment shown in FIG. 22, claw portions 141c are formed at approximately equal intervals in six locations of the annular portion 141b, but the number of claw portions 141c can be arbitrarily set.

The annular portion 141b of the lock member 141 includes a plurality of claw portions 141c formed at substantially equal intervals along the circumferential direction. The first claw portion 141c1 (FIG. 14) of the plurality of claw portions is formed on the side opposite to the lock operation portion 141a with the annular shape portion 141b interposed therebetween. In other words, the lock operation portion 141a and the first claw portion 141c1 are formed to extend from the annular shape portion 141b in a state where a part of each other overlaps in the radial direction of the annular shape portion 141b. The 3rd nail | claw part 141c3 is formed in the position facing the 1st nail | claw part 141c in the annular | circular shaped part 141b.

In the state where the module 200 is mounted on the apparatus main body 100, the place where water or foreign matter or the like is most likely to enter is the position of the lock operation unit 141a in the circumferential direction of the lock member 141. Therefore, providing the first claw portion 141c1 in the vicinity of the lock operation portion 141a is effective in suppressing the intrusion of water or the like into the apparatus main body 100. Thereby, the waterproof performance in the lock position of the lock member 141 increases.

In this embodiment, the play between the apparatus main body 100 and the module 200 can be suppressed by arranging a plurality of claw portions at equal intervals along the circumferential direction. In addition, since the force (shearing force) applied to the claw portion can be dispersed when the user tries to separate the module 200 from the device main body 100, it is possible to avoid excessive force from acting on the claw portion.

In the present embodiment, the second claw portion 201a2 and the fourth claw portion 201a4 (FIG. 11) have different maximum thicknesses in the direction orthogonal to the optical axis of the imaging optical system, and the fourth claw portion 201a4 The maximum thickness is larger than that of the second claw portion 201a2. By increasing the thickness of one of the two claw portions opposed in the radial direction, it becomes easy to remove the backlash. Further, since the gap between the device main body 100 and the module 200 can be made as small as possible at the formation position of the lock operation portion 141a that can be an intrusion path for water or the like, it is effective for measures against drip-proofing and dust-proofing.
