DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described through embodiments of the invention. However, the following embodiments do not limit the claimed invention, and all combinations of features described in the embodiments are the solution of the invention. It is not always essential to the means.
[0018]
FIG. 1 shows the appearance of the digital camera 10. 1A shows the front surface, and FIG. 1B shows the right side surface. A lens unit 102, a viewfinder 14, a shutter 22, a flash unit 24, and a microphone 16 for inputting sound are provided on the front surface of the digital camera 10, and an input / output terminal 20 and a memory card insertion slot 26 are provided on the right side surface of the digital camera 10. , And a speaker 18 for outputting sound. The flash unit 24 in FIG. 1A is located at the protruding position, and the flash unit 24 in FIG. 1B is located at the storage position. Thus, the flash unit 24 is provided so as to be movable between the storage position and the protruding position.
[0019]
The speaker 18 is provided below the flash unit 24 on the right side surface of the digital camera 10. Since the speaker 18 is provided on the right side of the digital camera 10, that is, on the opposite side of the grip portion 28, the speaker 18 is not covered with the user's hand even when the user performs shooting. Therefore, even when the user holds the digital camera 10 with his / her hand on the grip portion 28, for example, when the user wants to output sound simultaneously with shooting, the user can listen to the sound in a good state. .
[0020]
The microphone 16 is disposed at the upper left part of the front surface, that is, below the shutter button 22. When the user takes an image, the user usually attaches the right hand to the grip portion 28 and presses the shutter button 22 with the index finger of the right hand. At this time, the microphone 16 is arranged at a position not covered with the right hand. Moreover, since it exists in the position comparatively separated from the other member, it is comparatively difficult to catch the noise which arises when another member operates. Therefore, the microphone 16 can capture external sound with little noise.
[0021]
The lens unit 102 is located on the right side of the front surface. The viewfinder 14 is located at the upper left part of the lens unit 102 and is provided so that at least a main part thereof is included inside the circumscribed rectangle of the lens unit 102. Accordingly, the space occupied by the lens unit 102 and the viewfinder 14 is small, and the digital camera 10 can be downsized.
[0022]
The lens unit 102 includes a lens 12, a lens cover 32, and an opening 30 provided in the front housing 100. The lens cover 32 is provided inside the front case 100 so as to be movable between the front side of the lens 12 and the front side, that is, between the bottom side of the digital camera 10. When shooting is not performed, the lens cover 32 is positioned in front of the lens 12 and protects the lens 12. When shooting, the lens cover 32 moves to the bottom side of the digital camera 10 and the lens 12 appears, enabling shooting.
[0023]
FIG. 2 shows the lens cover 32 attached to the back surface of the front housing 100 and the back surface of the front housing 100 of the digital camera 10. The cover support shaft 60 is fixed to the front casing 100, and the cover support shaft 60 supports the lens cover 32 in a rotatable manner. Accordingly, the lens cover 32 can be rotated between the open position 200 and the closed position 202 of the lens unit 102 around the cover support shaft 60. Further, on the back surface of the front housing 100, the lens cover moving unit 104 to which the lens cover 32 is to be moved is provided in a concave shape with respect to other parts, and the lens cover 32 moves the lens cover moving unit 104. In addition, a guide 44 is provided at the boundary line of the lens cover moving unit 104 along a trajectory in which the outer peripheral portion rotates when the lens cover 32 rotates. Thereby, the lens cover 32 can be stably rotated.
[0024]
FIG. 3 is a view of the lens cover 32 as viewed from the axial direction of the cover support shaft 60. The lens cover 32 has a convex portion 42 provided linearly on the outer peripheral portion thereof. The convex portion 42 contacts the front housing 100 when the lens cover 32 rotates between the open position 200 and the closed position 202. The convex part 42 is provided over substantially the entire circumference of the outer peripheral part. As described above, since the convex portion 42 is linearly provided, that is, continuously, the lens cover 32 is pulled on the surface of the front housing 100 when rotating between the open position 200 and the closed position 202. It can slide smoothly on the front housing 100 without being caught.
[0025]
Further, the longest distance portion and the shortest distance portion from the cover support shaft 60 of the convex portion 42 are cut out. Thus, since the convex part 42 of the longest distance part is notched, the distance from the cover spindle 60 to the longest part is shortened, and the area occupied by the locus of rotation of the lens cover 32 may be reduced. it can.
[0026]
FIG. 4 is a cross-sectional view of the lens cover 32 as seen from a direction perpendicular to the axial direction of the cover support shaft 60. The convex portion 42 is half-punched, slightly convex toward the front housing 100 side, and the convex upper portion abuts against the front housing 100. As another form, the convex part 42 may be bent in the state inclined to the front housing | casing 100 side compared with parts other than the convex part 42 of the lens cover 32. FIG. Also in this case, the convex portion 42 abuts on the front housing 100. The lens cover 32 rotates between the open position 200 and the closed position 202 in a state where the upper portion of the convex portion 42 is in contact with the front housing 100. Therefore, the sliding resistance is less than that in the case where the entire lens cover 32 is rotated with the front cover 100 in contact with the lens cover 32. Therefore, the lens cover 32 can be rotated with a smaller force. Moreover, since parts other than the convex part 42 among the lens covers 32 do not contact with other members, they are not damaged when sliding. Therefore, a portion of the lens cover 32 exposed to the outside from the opening 30 can be kept in a good appearance without being damaged even if the lens cover 32 is repeatedly opened and closed. As another form, a convex member may be bonded to the outer periphery of the lens cover 32.
[0027]
FIG. 5 is a perspective view showing the lens cover 32 mounted on the back surface of the front housing 100 and the configuration responsible for opening and closing the lens cover 32. The opening and closing of the lens cover 32 is realized by the cover support shaft 60, the torsion spring 62, the pin 64, and the drive unit 70. The shaft holding portion 34 is provided in a substantially U shape, and the upper surface 36 and the lower surface 38 of the three surfaces forming the U shape are the first through hole 48 and the second through hole 50 through which the cover support shaft 60 passes. The lower surface 38 further has a pin 64. The side surface 40 forming the U-shape has a latching portion 46. The cover support shaft 60 penetrates the first through hole 48 and the second through hole 50 and supports the shaft holding portion 34 so as to be rotatable. The lens cover 32 is provided integrally with the shaft holding portion 34 and moves together with the shaft holding portion 34.
[0028]
When the lens cover 32 is located at the closed position 202 on the side surface 40, the latching portion 46 is provided on the side of the upper end portion 52 located on the upper side of the digital camera 10 and on the upper surface 36 side. Yes. The torsion spring 62 is fitted to the cover support shaft 60 and is positioned between the upper surface 36 and the lower surface 38, and one end thereof is hooked on the hooking portion 46 of the side surface 40. The latching portion 46 is pressed by the torsion spring 62 and is urged clockwise. Accordingly, the lens cover 32 is always urged from the open position 200 to the closed position 202. Accordingly, the lens cover 32 can be rotated from the open position 200 to the closed position 202.
[0029]
On the other hand, the rotation of the lens cover 32 from the closed position 202 to the open position 200 is realized by an urging force from the drive unit 70. The drive unit 70 has a U-shape and has a recess 74 and a drive unit support shaft 72 that pinch the pin 64 so as to be movable. The drive unit 70 rotates around the drive unit support shaft 72 with the pin 64 movably sandwiched in the recess 74. When the shaft holding part 34 moves between the open position 200 and the closed position 202, the distance between the pin 64 and the drive part support shaft 72 changes. The recess 74 of the drive unit 70 is formed so that the pin 64 does not come off from the recess 74 even when the shaft holding unit 34 is located at the open position 200. As a result, the pin 64 can be fitted into the recess 74 stably.
[0030]
The drive unit 70 urges the pin 64 in the direction from the closed position 202 to the open position 200 by a driving force. Accordingly, the lens cover 32 can be rotated from the closed position 202 to the open position 200 by the urging force from the driving unit 70. The urging force from the drive unit 70 is larger than the urging force that the torsion spring 62 applies to the lens cover 32. Accordingly, when the lens cover 32 is urged by the driving unit 70, the lens cover 32 can be rotated from the closed position 202 to the open position 200 against the urge from the torsion spring 62.
[0031]
The drive unit 70 also supplies or stops the urging force to the pin 64. When not urged by the drive unit 70, the lens cover 32 is positioned at the closed position 202 by the urging of the torsion spring 62. When a biasing force is supplied from the driving unit 70 to the pin 64, the lens cover 32 rotates from the closed position 202 to the open position 200 against the biasing from the torsion spring 62 by the biasing of the driving unit 70. To do. When the drive unit 70 stops supplying the urging force, the lens cover 32 returns to the closed position 202 from the open position 200 again by the urging of the torsion spring 62. In this way, the lens cover 32 is always urged from the open position 200 to the closed position 202 by the torsion spring 62 and further closed against the urging of the torsion spring 62 when urged by the drive unit 70. Since the lens cover 32 rotates in the direction from the position 202 to the open position 200, the lens cover 32 can freely move to the open position 200 and the closed position 202.
[0032]
Here, the operation of the lens cover 32 will be described. When the digital camera 10 is stopped, the lens cover 32 is located at the closed position 202. When the power is turned on by the user, the drive unit 70 is driven to bias the pin 64. In conjunction with this, the lens cover 32 opens and the lens 12 appears. The preparation for shooting is now complete, and the user can perform shooting. The trigger that the drive unit 70 drives, that is, the trigger that the lens cover 32 rotates may be other than the power-on, for example, the lens cover 32 may be opened by an input from the user. When the photographing is finished and the operation of the drive unit 70 is stopped by an instruction from the user, the lens cover 32 is closed by the urging force from the torsion spring 64. Thus, the operation of the lens cover 32 is completed.
[0033]
FIG. 6 is a perspective view showing the shaft holding portion 34 and the cover support shaft 60. The first through hole 48 has a slightly larger diameter than the second through hole 50. For example, the diameter may be about 5% larger. Thus, since the lower surface 38 is loosely fitted by the cover support shaft 60, the lower surface 38 can freely move on the spherical surface with the first through hole 48 as the center.
[0034]
The side surface 40 is urged clockwise by the torsion spring 62 about the cover support shaft 60. The latching portion 46 is located on the upper surface 36 side, and the second through hole 50 is held so as to be movable on a spherical surface centered on the first through hole 48. For this reason, the lower surface 38 is stationary in a state where the side on the lower end portion 54 side facing the upper end portion 52 of the lens cover 32 protrudes toward the front casing 100 and the second through hole 50 and the cover support shaft 60 are in contact with each other. To do. Since the lens cover 32 is provided integrally with the shaft holding portion 34, that is, the lower surface 38, at this time, the lens cover 32 moves together with the lower surface 38 and tilts so that the lower end portion 54 side protrudes toward the front housing 100 side. Accordingly, the cover support shaft 60 can stably hold the lens cover 32 in a state where the lower end portion 54 side always protrudes toward the front housing 100 side. Further, since the urging force for tilting the lens cover 32 is applied from the torsion spring 62, the lens cover 32 can be tilted without requiring electric power.
[0035]
Further, the degree of inclination of the lens cover 32 is determined by the size of the diameter of the second through hole 50 and the distance from the first through hole 48 to the second through hole 50. Therefore, at the design stage, by determining the size of the second through hole 50 and the distance from the first through hole 48 to the second through hole 50, the degree of the protrusion of the lens cover 32 can be freely set. Can do.
[0036]
FIG. 7 is a cross-sectional view of the front case 100 and the lens cover 32 when the lens cover 32 is in the closed position 202 as viewed from the right side of the digital camera 10. The lens cover 32 is provided inside the front housing 100, and the opening 30 is located on the front surface of the lens 12. In this figure, the lens cover 32 is located on the front surface of the lens portion 102, and the opening 30 is located on the front surface of the lens cover 32.
[0037]
A first clearance 84 between the lower end portion 54 of the lens cover 32 located on the bottom side of the front housing 100 and the lower portion 82 facing the lower end portion 54 of the opening portion 30 is formed between the upper end portion 52 and the opening portion 30. The lens cover 32 is inclined with respect to the opening 30 so that the lower end 54 side protrudes toward the front housing 100 so that the second clearance 86 is less than the second clearance 86 between the position facing the upper end 52. The positional relationship between the opening 30 and the lens cover 32 as shown in this drawing is realized by the shapes of the torsion spring 62 and the shaft holding portion 34 described with reference to FIG. Thus, since the 1st clearance 84 is small, it can prevent that dust etc. mix from the 1st clearance 84 in the state where the lens cover 32 was closed, and can close the lens cover 32 in a state with a desirable appearance. it can.
[0038]
FIG. 8 is a perspective view showing the shaft holding portion 34 and the cover support shaft 60 in the second embodiment. The shaft holding portion 34 of the present embodiment is provided in an approximately L shape, and in this respect, the present embodiment is different from the first embodiment in which the shaft holding portion 34 is provided in a U shape. The short surface 96 that forms the short side of the L-shape has a through hole that penetrates the cover support shaft 60, and a first opening 90 and a second opening 92 of the through hole are provided on the front surface 76 and the back surface 78 of the short surface 96, respectively. It has been. The front surface through-hole 92 has a larger diameter than the back surface through-hole 90, and the through-hole is provided in a truncated cone shape from the back surface through-hole 90 to the front surface through-hole 92. Accordingly, the front surface 78 can freely move on a spherical surface centered on the back surface through-hole 90. The long surface 94 forming the long side of the L-shape has a hooking portion 48 for hooking the torsion spring 62 at a position on the upper surface 52 side of the lens cover 32 and on the side opposite to the short surface 96 of the long surface 94. .
[0039]
When the shaft holding portion 34 is urged by the torsion spring 62, the short surface 96 includes the cover support shaft 60, the end portion on the lower end portion 54 side of the first opening 90, the cover support shaft 60, and the second opening 92. Of these, the end portion on the upper end portion 52 side facing the end portion of the first opening 90 and the cover support shaft 60 are in contact with each other, and the lower end portion 54 side of the lens cover 32 comes to rest in a state of protruding toward the front surface 100 of the housing. It has a sufficient thickness. That is, in this case as well, as in the first embodiment, the lens cover 32 depends on the size of the diameter of the front surface through-hole 92 and the distance from the rear surface through-hole 90 to the front surface through-hole 92, that is, the thickness of the short surface 96. Can determine the degree of squeeze. The other configuration is substantially the same as that of the shaft holder 34 in the first embodiment.
[0040]
Thus, also in this embodiment, the lens cover 32 is brought into contact with the two through holes by the biasing force of the torsion spring 62, so that the lower end portion 54 side of the lens cover 32 faces the front surface. It can be stably held in a state of being pushed out to the housing 100 side. The degree of inclination can be designed at a desired angle by determining the size of the diameter of the surface through-hole 92 and the thickness of the short surface 96.
[0041]

Various modifications or improvements can be added to the above embodiment. It is apparent from the description of the scope of claims that embodiments with such changes or improvements can be included in the technical scope of the present invention.
[0042]
As such a first modified example, in the present embodiment, the second through hole 50 has a larger diameter than the first through hole 48, but the first through hole 48 and the second through hole 50 are the same. In this case, the first through hole 48 and the second through hole 50 are provided at positions where the lower end portion 54 of the lens cover 32 protrudes toward the front casing 100 on the upper surface 36 and the lower surface 38, respectively. It may be done. Even in this case, the lens cover 32 can always be tilted so that the lower end portion 54 protrudes toward the front housing 100 side.
[0043]
As a second modification, in the present embodiment, the torsion spring 62 is fitted to the cover support shaft 60 between the upper surface 36 and the lower surface 38, but is closer to the front housing 100 than the upper surface 36. It may be provided. In this case, the side surface 40 may be provided extending to the front housing 100 side.
