Description

Technical Field

[0001] The present invention relates to a camera device. Background Art

[0002] Generally, cameras are often provided with an aperture for taking photos in an optimal exposure state (see, for example, Patent Document 1). Conventionally, such an aperture is used to adjust the amount of light, and is not used, for example, to add aesthetic or artistic effects to the taken image. In the case of digital photos, it is also possible to add aesthetic or artistic effects to the image by correcting the data after taking the photo, but such post-editing is not possible, especially in the case of analog photos, and therefore a technology for obtaining an image with aesthetic or artistic effects is required.

[0003] Patent Document 1: Japanese Patent Application Publication No. 2016-133627 Summary of the invention

[0004] The present invention has been made in view of the problems of the prior art, and an object of the present invention is to provide a camera device capable of easily capturing images with aesthetic and / or artistic effects, and a switching switch for use in such a camera device.

[0005] According to one embodiment of the present invention, a camera device is provided that can easily capture images with aesthetic and / or artistic effects. The camera device has at least one lens of a camera area for imaging a subject on a photo film and aperture blades arranged in front of the at least one lens. The at least one aperture blade is configured to be movable between an aperture position that causes vignetting to occur at the peripheral portion of the camera area and an open position that is radially outward of the aperture position. The camera device also has a switching switch, which includes an operating lever that can be moved by a user's operation and a working lever connected to the at least one aperture blade, and the working lever moves the at least one aperture blade between the aperture position and the open position as the operating lever moves.

[0006] According to another embodiment of the present invention, a switch of a simple structure is provided, which can easily switch the switching state by moving the operating rod in the circumferential direction. The switch has: a base; an operating rod, which can move in the circumferential direction on the base with the first axis as the center; a working rod, which can rotate with the second axis as the center; and a cam mechanism, which converts the movement of the operating rod into the rotation of the working rod. The cam mechanism includes: a cam groove, which is provided on one of the operating rod and the working rod; and a follower, which is provided on the other of the operating rod and the working rod, and can move in the cam groove while engaging with the cam groove. The switch also includes a force applying portion for applying force to the follower of the cam mechanism. The cam groove of the cam mechanism includes an inner portion and an outer portion located at a position radially outward of the inner portion relative to the first axis, and the cam groove extends along the circumferential direction between the inner portion and the outer portion. The follower of the cam mechanism is movable between a first follower position located at the inner side of the cam groove and a second follower position located at the outer side of the cam groove. The force applying portion is configured to press the follower toward the first follower position when the follower of the cam mechanism is located closer to the first follower position than the reference follower position, and to press the follower toward the second follower position when the follower of the cam mechanism is located closer to the second follower position than the reference follower position.

[0007] According to still another aspect of the present invention, there is provided a camera device having the above-mentioned switching switch.

[0008] According to the present invention, the user can operate the operating lever of the switching switch to move the aperture blades between the aperture position and the open position. When the aperture blades are at the aperture position, vignetting occurs at the peripheral portion of the imaging area of ​​the photo film, so that the peripheral portion of the captured image can be darkened. As a result, a photo with an aesthetic and / or artistic effect of making the vicinity of the center more prominent, i.e., a vignetting effect, can be captured. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Below, refer to Figures 1 to 13 Embodiments of the camera device of the present invention are described in detail. Figures 1 to 13 In the present invention, the same or equivalent components are marked with the same reference numerals and repeated descriptions are omitted. Figures 1 to 13 In the following description, unless otherwise specified, terms such as "first" and "second" are used only to distinguish components from each other and do not indicate a specific order or sequence.

[0029] Figure 1 1 is a perspective view showing a camera device 1 in one embodiment of the present invention. The camera device 1 in this embodiment is a camera that uses a photo film that is automatically developed after shooting (instant camera), but the present invention can of course be applied to cameras other than such instant cameras. In addition, in this embodiment, for convenience, the direction along the optical axis direction toward the subject ( Figure 1 The +Z direction in the figure is referred to as “front” or “forward”, and the direction toward the camera device 1 (-Z direction) is referred to as “rear” or “rearward”.

[0030] like Figure 1 As shown, the camera device 1 includes a front cover 2, a rear cover 3 mounted behind the front cover 2, a top cover 4 sandwiched between the front cover 2 and the rear cover 3, and a lens barrel 5 in which a lens unit is stored. A viewfinder window 6 is formed on the front cover 2, and a flash window 7 is arranged adjacent to the viewfinder window 6. In addition, a release button 8 is arranged on the -Y direction side of the viewfinder window 6. A discharge slit 4A extending in the X direction is formed in the top cover 4, and the developed photo film after shooting is discharged from the discharge slit 4A.

[0031] The lens barrel 5 includes an outer cylinder 10, an operating ring 11 covering the outer periphery of the outer cylinder 10, and an inner cylinder 12 that can extend axially from the radial inner side of the outer cylinder 10. The operating ring 11 can rotate outside the outer cylinder 10, and by rotating the operating ring 11 relative to the outer cylinder 10, the inner cylinder 12 is extended forward by an extension mechanism (not shown).

[0032] Figure 2 1 is a perspective view showing the inner tube portion 12. Figure 2 As shown, the inner cylinder portion 12 includes: a cylinder body 14, which is cylindrical; a cover plate 16, which is annular and installed in front of the cylinder body 14; three aperture blades 21 to 23; a switching switch 30, which can switch the position of the aperture blades 21 to 23 between the aperture position and the open position; and one or more lenses 90, which image the subject in the camera area on the photo film. Figure 2 The state in which the aperture blades 21 to 23 are in the aperture position by the switching switch 30 is shown. In addition, the inner cylinder 12 further includes aperture blades (not shown) for adjusting the amount of light projected onto the imaging area on the photo film. The aperture blades 21 to 23 in this embodiment are used to darken the peripheral portion of the imaging area on the photo film, and are different from the aperture blades (not shown) for adjusting the amount of light projected onto the imaging area.

[0033] Figure 3 FIG. 1 is an exploded perspective view of some components of the inner tube portion 12. Figure 3 As shown, the inner cylinder 12 includes: a first substrate 40 (base) which is substantially disk-shaped; a front panel 18 which is disposed between the first substrate 40 and the cover plate 16; a pair of baffle blades 19A and 19B which are disposed in a space formed between the first substrate 40 and the front panel 18; an operating rod 50 which is disposed between the first substrate 40 and the cover plate 16; a second substrate 60 which is disposed behind the first substrate 40; an operating rod 70 which is disposed in a space formed between the first substrate 40 and the second substrate 60; and a force applying portion 80 which applies a force to the operating rod 70. The aperture blades 21 to 23 are disposed in a space formed between the first substrate 40 and the second substrate 60. The second substrate 60 has shafts 61 to 64 extending in the +Z direction.

[0034] Before shooting, the barrier blades 19A and 19B are Figure 1 However, during shooting, the baffle blades 19A and 19B are moved in directions away from each other by a driving mechanism (not shown) so that light from the outside is incident on the lens in the inner cylinder portion 12 through the opening 18A of the front panel 18. Figure 2 and Figure 3 The state at the time of photographing is shown, in which the barrier blades 19A and 19B are moved to positions separated from each other.

[0035] The switch 30 in the present embodiment includes a portion of a first substrate 40 , an operating lever 50 , an operating lever 70 , and a force applying portion 80 . Figure 4 It is extracted Figure 2 The top view of the components of the inner cylinder 12 shown in FIG. Figure 4 As shown, the operating lever 50 of the changeover switch 30 is disposed near the peripheral edge of the first substrate 40. As described later, the operating lever 50 is configured to be movable in the circumferential direction around the optical axis P (first axis) by a user's operation.

[0036] Figure 5A is a perspective view of the operating lever 50, Figure 5B It is a top view. Figure 5C This is a bottom view. Figure 4 and FIG. 5A to FIG. 5C As shown in FIG. 4 , the operating lever 50 includes: an arc-shaped plate portion 51 extending along an arc centered on the optical axis P when the operating lever 50 is arranged on the first substrate 40; an operating protrusion 52 protruding from the arc-shaped plate portion 51 in the +Z direction; a rail portion 53 extending along the same arc as the arc-shaped plate portion 51 on the −Z direction side of the arc-shaped plate portion 51; and an extension portion 54 extending in a plate shape from the rail portion 53. In addition, a concave-convex portion for facilitating the operation of the operating lever 50 is formed at the front end of the operating protrusion 52.

[0037] The arc-shaped plate portion 51 has a protrusion 51A protruding in the +Z direction on the front surface and a protrusion 51B protruding in the -Z direction on the rear surface. These protrusions 51A and 51B respectively have the function of reducing the friction between the operating lever 50 and the plates 16 and 40 by contacting the cover plate 16 and the first substrate 40. In addition, a mark 51C indicating that the aperture blades 21 to 23 are located at the aperture position is formed on the front surface of the arc-shaped plate portion 51.

[0038] like Figure 3 As shown, a window 17 extending in an arc shape is formed on the cover plate 16 located in front of the operating rod 50. Figure 1As shown in FIG. 1 , the operating protrusion 52 of the operating lever 50 is located inside the window 17. In addition, the mark 51C on the arc-shaped plate portion 51 is Figure 1 The state shown, i.e., the state in which the diaphragm blades 21 to 23 are located at the diaphragm position, is visible to the outside through the window 17 of the cover plate 16, and as described later, when the operating lever 50 is moved in the circumferential direction (when the diaphragm blades 21 to 23 are located at the open position), they are hidden behind the cover plate 16. Therefore, the user can recognize that the diaphragm blades 21 to 23 are located at the diaphragm position by checking the mark 51C on the operating lever 50.

[0039] like Figure 5C As shown, the rail portion 53 of the operating rod 50 has thick wall portions 57A and 57B protruding radially outward at both ends. In addition, the rail portion 53 has a raised portion 53A raised in the -Z direction on the rear surface, and the raised portion 53A has the function of reducing the friction between the operating rod 50 and the first substrate 40 by contacting the first substrate 40.

[0040] like Figure 4 and FIG. 5A to FIG. 5C As shown in FIG. 1 , a cam groove 56 is formed in the expansion portion 54 of the operating rod 50. The cam groove 56 includes an inner portion 56A located radially inward relative to the optical axis P and an outer portion 56B located radially outward relative to the optical axis P than the inner portion 56A. The cam groove 56 extends in the circumferential direction as a whole between the inner portion 56A and the outer portion 56B. As described later, the shape of the cam groove 56 is determined by the relationship between the rotation angle of the working rod 70 and the force applied to the working rod 70 by the force applying portion 80.

[0041] Return to Figure 3 A circular hole 21A and a long hole 21B are formed in the aperture blade 21, a circular hole 22A and a long hole 22B are formed in the aperture blade 22, and a circular hole 23A and a long hole 23B are formed in the aperture blade 23. The shaft 61 of the second substrate 60 is inserted into the circular hole 21A of the aperture blade 21, and the shaft 61 is received by the circular hole 21A of the aperture blade 21, so that the aperture blade 21 can rotate around the shaft 61 as the center. Similarly, the shaft 62 of the second substrate 60 is inserted into the circular hole 22A of the aperture blade 22, so that the aperture blade 22 can rotate around the shaft 62 as the center. In addition, the shaft 63 of the second substrate 60 is inserted into the circular hole 23A of the aperture blade 23, so that the aperture blade 23 can rotate around the shaft 63 as the center.

[0042] Figure 6 70 is a three-dimensional diagram of the working rod. Figure 6As shown, the working rod 70 includes: a shaft portion 72, which is formed with a shaft hole 71 extending in the Z direction; a first arm portion 73, which extends from the shaft portion 72; a working portion 74, which is cylindrical and extends from the end of the first arm portion 73 in the +Z direction; a second arm portion 75, which extends from the shaft portion 72 in a direction different from the first arm portion 73; and a driven portion 76, which extends from the end of the second arm portion 75 in the +Z direction. The shaft 64 of the second substrate 60 is inserted into the shaft hole 71 of the shaft portion 72 (see Figure 3 ). In this way, the shaft 64 is received by the shaft hole 71 of the shaft portion 72, so that the working rod 70 can rotate around the shaft 64 (second shaft). The driven portion 76 includes a large diameter portion 77 having a relatively large diameter and a small diameter portion 78 located on the +Z direction side of the large diameter portion 77 and having a smaller diameter than the large diameter portion 77.

[0043] The working portion 74 of the working rod 70 is inserted into the long holes 21B to 23B of the aperture blades 21. The outer diameter of the working portion 74 is slightly smaller than the width of each long hole 21B to 23B (the width in the direction perpendicular to the direction in which the long holes 21B to 23B extend), and the working portion 74 can move in each long hole 21B to 23B while engaging with the long holes 21B to 23B of each aperture blade 21 to 23. Therefore, when the working rod 70 rotates around the shaft 64, the working portion 74 moves in the long holes 21B to 23B of each aperture blade 21, while applying force to the aperture blades 21 to 23 by engaging with the long holes 21B to 23B, so that the aperture blades 21 to 23 rotate around the shafts 61 to 63. In this way, the diaphragm blades 21 to 23 are connected to the actuating rod 70 via the actuating portion 74 , and rotate about the respective shafts 61 to 63 (rotational axes) as the actuating rod 70 rotates.

[0044] Figure 7 40 is a three-dimensional diagram of the first substrate 40. Figure 4 and Figure 7 As shown, the first substrate 40 has: an outer wall 41 having an inner circumferential surface 41A along an arc centered on the optical axis P (first axis); a first inner wall 42 having an outer circumferential surface 42A along an arc centered on the optical axis P on the radial inner side of the outer wall 41; a first support portion 43 located between the outer wall 41 and the first inner wall 42; a second inner wall 44 having an outer circumferential surface 44A along an arc centered on the optical axis P on the radial inner side of the first inner wall 42; a second support portion 45 located between the outer wall 41 and the second inner wall 44; and a spring fixing portion 46 protruding from the first support portion 43 in a direction along an axis Q (third axis) perpendicular to the optical axis P. An opening 49 is formed in the center of the first substrate 40. In addition, the outer wall 41 has stoppers 41B and 41C protruding radially inward from the inner circumferential surface 41A.

[0045] The second support portion 45 is formed with an arc groove 48 extending along an arc centered on the axis 64 of the second substrate 60 . Figure 6 The driven portion 76 of the illustrated actuating rod 70 is inserted into the arc groove 48 from the rear (−Z direction side) of the first substrate 40 , and the driven portion 76 moves inside the arc groove 48 as the actuating rod 70 rotates around the shaft 64 .

[0046] The first support portion 43 and the second support portion 45 have the same height in the Z direction, and a recessed portion 47 is formed between the first support portion 43 and the second support portion 45. The spring fixing portion 46 described above is located in the recessed portion 47.

[0047] The above-mentioned operating rod 50 is arranged on the +Z direction side of the first support part 43 and the second support part 45. More specifically, the operating rod 50 is arranged on the +Z direction side of the first substrate 40 in such a manner that a part of the rail part 53 of the operating rod 50 is located on the +Z direction side of the first support part 43, and the extension part 54 of the operating rod 50 and a part of the rail part 53 are located on the +Z direction side of the second support part 45.

[0048] Figure 8 The partial cross-sectional view is a view of the operation rod 50, the first substrate 40 and the working rod 70 cut by a plane perpendicular to the optical axis P in a manner including the track portion 53 and the extension portion 54 of the operation rod 50. Figure 4 and Figure 8 As shown, the large diameter portion 77 of the follower portion 76 of the working rod 70 is located inside the arc groove 48 of the first substrate 40, and the small diameter portion 78 of the follower portion 76 protrudes from the arc groove 48 to the +Z direction side and is located inside the cam groove 56 of the operating rod 50 arranged on the +Z direction side of the second support portion 45.

[0049] The outer diameter of the small diameter portion 78 of the follower portion 76 of the working rod 70 is slightly smaller than the width of the cam groove 56 of the operating rod 50 (the width along the direction perpendicular to the direction in which the cam groove 56 extends), and the small diameter portion 78 can move in the cam groove 56 while engaging with the cam groove 56 of the operating rod 50.

[0050] like Figure 8As shown, the thick-walled portion 57A of the track portion 53 of the operating rod 50 is sandwiched between the inner peripheral surface 41A of the outer wall 41 of the first substrate 40 and the outer peripheral surface 42A of the first inner wall 42, and is guided by the inner peripheral surface 41A of the outer wall 41 and the outer peripheral surface 42A of the first inner wall 42. In addition, the thick-walled portion 57B of the track portion 53 of the operating rod 50 contacts the inner peripheral surface 41A of the outer wall 41 of the first substrate 40, and the extended portion 54 contacts the outer peripheral surface 44A of the second inner wall 44. That is, the extended portion 54 and the thick-walled portion 57B of the operating rod 50 are sandwiched between the inner peripheral surface 41A of the outer wall 41 of the first substrate 40 and the outer peripheral surface 44A of the second inner wall 44, and are guided by the inner peripheral surface 41A of the outer wall 41 and the outer peripheral surface 44A of the second inner wall 44. With such a structure, the operating rod 50 can move circumferentially with the optical axis P as the center. Below, in Figure 8 In the present invention, the direction in which the operating rod 50 moves clockwise around the optical axis P is referred to as an “opening direction”, and the direction in which the operating rod 50 moves counterclockwise around the optical axis P is referred to as a “closing direction”.

[0051] like Figure 8 As shown, a force applying portion 80 is accommodated in the recess 47 between the first support portion 43 and the second support portion 45 of the first substrate 40. The force applying portion 80 is included in the recess 47 and can move along the axis Q (refer to Figure 7 ) and a coil spring 82 as a biasing portion that biases the contact 81 in a direction along the axis Q.

[0052] Fig. 9 81 is a top view of the contact. Fig. 9 As shown, the contact 81 includes a pentagonal prism-shaped contact body 83 and a spring fixing portion 84 extending from the contact body 83 in a direction along the axis Q. The contact body 83 has a top 85 formed into a rounded corner and inclined portions 86, 87 extending from the top 85 to both sides. The top 85 and the inclined portions 86, 87 of the contact body 83 are configured to contact the large diameter portion 77 of the driven portion 76 of the working rod 70 located in the circular arc groove 48.

[0053] The spring fixing portion 84 of the contact 81 is inserted into one end of the coil spring 82, and the spring fixing portion 46 of the first substrate 40 is inserted into the other end (see Figure 7 ). Thus, the coil spring 82 is fixed in a compressed state between the contact body 83 and the first support portion 43 of the first substrate 40. Since the contact 81 is urged in the direction along the axis Q by the coil spring 82, any portion of the top portion 85 and the inclined portions 86 and 87 contacts the large diameter portion 77 of the driven portion 76 of the operating rod 70 to press the driven portion 76.

[0054] FIG. 10A to FIG. 10C The diagram schematically shows the relationship between the components in each state of the switch 30 . Fig. 10A The state in which the aperture blades 21 to 23 are switched to the aperture position by the switching switch 30 is shown. Figure 4 and Figure 8 The status shown is the status of Fig. 10B The state in which the aperture blades 21 to 23 are being switched from the aperture position to the open position or from the open position to the aperture position by the switching switch 30 is shown. Fig. 10C FIG. 2 shows a state where the aperture blades 21 to 23 are switched to the open position by the switch 30. Fig. 10A and Fig. 10C As shown in FIG. 1 , the open position of each of the aperture blades 21 to 23 is located radially outward of the aperture position.

[0055] like Fig. 10A As shown, when the aperture blades 21 to 23 are located at the aperture position, a portion of the aperture blades 21 to 23 extends inward from the edge of the opening 49 of the first substrate 40, and the light incident on the lens inside the inner cylinder 12 is blocked by the extended portion of the aperture blades 21 to 23. Due to the extended portion of the aperture blades 21 to 23, vignetting occurs at the peripheral portion of the imaging area of ​​the photo film, and the peripheral portion of the captured image becomes dark. As a result, a photo with an aesthetic and / or artistic effect that makes the vicinity of the center more prominent, i.e., a vignetting effect, can be captured. In this state, the small diameter portion 78 of the follower portion 76 of the operating lever 70 is located at the inner side portion 56A of the cam groove 56 of the operating lever 50. The position of the operating lever 70 at this time is referred to as the "first operating lever position", and the position of the follower portion 76 is referred to as the "first follower position".

[0056] When the user operates the operation protrusion 52 (see Figure 1 ) is operated so that the operating lever 50 is moved from Fig. 10A When the state shown is moved in the opening direction, the small diameter portion 78 of the follower portion 76 engaged with the cam groove 56 moves along the shape of the cam groove 56 of the operating lever 50, and accordingly, the operating lever 70 rotates counterclockwise around the shaft 64. As described above, since the operating portion 74 of the operating lever 70 is engaged with the long holes 21B to 23B of the diaphragm blades 21 to 23, the diaphragm blade 21 rotates clockwise around the shaft 61, the diaphragm blade 22 rotates clockwise around the shaft 62, and the diaphragm blade 23 rotates counterclockwise around the shaft 63 by the counterclockwise rotation of the operating lever 70.

[0057] Here, if Fig. 10AAs shown, when the follower portion 76 of the working rod 70 is located in the first follower position, the large diameter portion 77 of the follower portion 76 contacts the inclined portion 86 of the contact 81. As described above, the contact 81 is biased by the coil spring 82, so the follower portion 76 is pressed by the inclined portion 86 of the contact 81 in a direction rotating clockwise around the shaft 64 (see arrow F1). Since the small diameter portion 78 of the follower portion 76 is engaged with the cam groove 56 of the operating rod 50, a force in the closing direction acts on the operating rod 50 by pressing the follower portion 76 clockwise. Therefore, in a state where no external force is applied to the operating rod 50, the force in the closing direction generated by the coil spring 82 acts on the operating rod 50, and the thick wall portion 57A of the track portion 53 of the operating rod 50 and the stop portion 41B of the first substrate 40 (see Figure 8 ) abuts against the first substrate 40, thereby maintaining the circumferential position of the operating rod 50. In this way, the stopper 41B of the first substrate 40 has the function of limiting the movement of the operating rod 50 in the closing direction. The position of the operating rod 50 at this time is referred to as the "first operating rod position".

[0058] exist Fig. 10A In the state shown, as described above, the coil spring 82 exerts a force in the closing direction on the operating rod 50, so when the user moves the operating rod 50 in the opening direction, a force exceeding the closing direction force of the coil spring 82 needs to be applied to the operating rod 50. When the user applies a force exceeding the closing direction force of the coil spring 82 to the operating rod 50 and the operating rod 50 moves from Fig. 10A When the operation lever 70 moves in the opening direction in the illustrated state, the contact portion between the large diameter portion 77 of the follower portion 76 of the operation lever 70 and the contact 81 moves from the inclined portion 86 toward the top portion 85 .

[0059] Fig. 10B The state where the contact portion between the large diameter portion 77 of the driven portion 76 and the contact 81 has moved to the top portion 85 is shown. The position of the driven portion 76 at this time is referred to as the "reference driven position". The driven portion 76 at the reference driven position is located on the axis Q, and at this position, the coil spring 82 does not apply a torque to the working rod 70.

[0060] When the user Fig. 10B When the operating lever 50 is further moved in the closing direction in the state shown in the figure, as described above, the small diameter portion 78 of the follower portion 76 moves along the shape of the cam groove 56 of the operating lever 50, and the actuating lever 70 rotates counterclockwise around the shaft 64, and each aperture blade 21 to 23 rotates to the closed position via the actuating portion 74 of the actuating lever 70. Fig. 10C Open position shown.

[0061] like Fig. 10CAs shown, when the aperture blades 21 to 23 are in the open position, the aperture blades 21 to 23 are located outside the edge of the opening 49 of the first substrate 40, and the light incident on the lens inside the inner cylinder 12 is not blocked by the aperture blades 21 to 23. In this state, the small diameter portion 78 of the follower portion 76 of the operating lever 70 is located at the outer side portion 56B of the cam groove 56 of the operating lever 50. The position of the operating lever 70 at this time is referred to as the "second operating lever position", and the position of the follower portion 76 is referred to as the "second follower position".

[0062] Here, if Fig. 10C As shown, when the follower portion 76 of the working rod 70 is located in the second follower position, the large diameter portion 77 of the follower portion 76 contacts the inclined portion 87 of the contact 81. As described above, the contact 81 is biased by the coil spring 82, so the follower portion 76 is pressed by the inclined portion 87 of the contact 81 in the direction of counterclockwise rotation around the shaft 64 (see arrow F2). Since the small diameter portion 78 of the follower portion 76 is engaged with the cam groove 56 of the operating rod 50, the follower portion 76 is pressed in the direction of counterclockwise rotation, thereby applying a force in the opening direction to the operating rod 50. Therefore, in a state where no external force is applied to the operating rod 50, the force in the opening direction generated by the coil spring 82 acts on the operating rod 50, and the thick wall portion 57B of the track portion 53 of the operating rod 50 and the stop portion 41C of the first substrate 40 (see Figure 8 ) abuts against the first substrate 40, thereby maintaining the circumferential position of the operating rod 50. In this way, the stopper 41C of the first substrate 40 has the function of limiting the movement of the operating rod 50 in the opening direction. The position of the operating rod 50 at this time is referred to as the "second operating rod position".

[0063] As described above, when the user moves the operating lever 50 from Fig. 10A When the first operating lever position shown in the figure is moved in the opening direction, a force exceeding the closing direction force of the coil spring 82 needs to be applied to the operating lever 50. However, if the large diameter portion 77 of the follower portion 76 passes over the top 85 from the inclined portion 86 of the contact 81 and contacts the inclined portion 87, the opening direction force of the coil spring 82 acts on the operating lever 50. Therefore, even if the user does not apply a force to the operating lever 50, the operating lever 50 is moved. Fig. 10C The second operation lever 50 is moved in position. Therefore, the user can feel the change in the force acting on the operation lever 50 (click feeling).

[0064] When the user moves the operating lever 50 from Fig. 10CWhen the second operating lever position shown in the figure moves in the closing direction, the small diameter portion 78 of the follower 76 moves along the shape of the cam groove 56 of the operating lever 50, and accordingly, the operating lever 70 rotates clockwise around the shaft 64, and the respective aperture blades 21 to 23 rotate via the operating portion 74 of the operating lever 70. At this time, as described above, a force in the opening direction is applied to the operating lever 50 by the coil spring 82, and therefore, when the user moves the operating lever 50 in the closing direction, a force exceeding the force in the opening direction of the coil spring 82 needs to be applied to the operating lever 50 until the large diameter portion 77 of the follower 76 passes over the top 85 of the contact 81. After the large diameter portion 77 of the follower 76 passes over the top 85 of the contact 81, the force in the closing direction of the coil spring 82 acts on the operating lever 50, and therefore, even if the user does not apply a force to the operating lever 50, the operating lever 50 moves in the closing direction. Fig. 10A The first operation lever 50 is shown to move in position. In this case, the user can also feel the change in the force acting on the operation lever 50 (click feeling).

[0065] As described above, in the present embodiment, the inclined portion 86 of the contact 81 functions as a first contact portion that contacts the large diameter portion 77 of the driven portion 76 located at a position closer to the first driven position than the reference driven position, and is biased by the coil spring 82 to press the driven portion 76 in the direction of clockwise rotation around the shaft 64. In addition, the inclined portion 87 of the contact 81 functions as a second contact portion that contacts the large diameter portion 77 of the driven portion 76 located at a position closer to the second driven position than the reference driven position, and is biased by the coil spring 82 to press the driven portion 76 in the direction of counterclockwise rotation around the shaft 64.

[0066] In the present embodiment, the inclined portion 86 and the inclined portion 87 of the contact 81 have mutually symmetrical shapes with respect to the top portion 85, but are not limited thereto. If the inclined portion 86 and the inclined portion 87 are mutually symmetrical shapes with respect to the top portion 85 as in the present embodiment, the same force acts on the operating rod 50 in the action of moving the operating rod 50 from the first operating rod position to the opening direction (opening action) and the action of moving the operating rod 50 from the second operating rod position to the closing direction (closing action), so that these two actions can be performed in a balanced manner. In addition, in the present embodiment, as described above, the reference driven position is located on the axis Q, so that the opening action and the closing action can be performed more balanced.

[0067] In this way, in the camera device 1 of the present embodiment, the user can move the aperture blades 21 to 23 between the aperture position and the open position by operating the operating lever 50 of the changeover switch 30. By moving the aperture blades 21 to 23 to the aperture position, vignetting is generated at the peripheral portion of the imaging area of ​​the photo film, so that the peripheral portion of the captured image becomes dark. As a result, a photo with an aesthetic and / or artistic effect that makes the vicinity of the center stand out more, that is, a vignetting effect, can be captured. As described above, in the case of digital photos, a vignetting effect can be added to the captured image by correcting the data after shooting, but in the case of analog photos, post-editing is not possible, so the function of adding such a vignetting effect is epoch-making, especially for a camera device that shoots analog photos.

[0068] In addition, when the follower portion 76 of the actuating lever 70 is located on the first follower position side relative to the reference follower position, it is pressed toward the first follower position by the contact 81, and when it is located on the second follower position side relative to the reference follower position, it is pressed toward the second follower position by the contact 81. Therefore, by moving the operating lever 50, the large diameter portion 77 of the follower portion 76 of the actuating lever 70 moves beyond the reference follower position, thereby making it easy to switch the switching state of the aperture blades 21 to 23, and the structure can also be simple. In addition, the user can feel the change in force, that is, the click feeling, of the follower portion 76 of the actuating lever 70 before and after it passes the reference follower position.

[0069] Here, the shape of the cam groove 56 of the operating lever 50 is described. The cam groove 56 of the operating lever 50 of the present embodiment has such a shape that the relationship between the rotation angle of the operating lever 70 centered on the shaft 64 and the press-in distance of the contact 81 along the direction of the axis Q when the follower 76 of the operating lever 70 moves from the first follower position to the reference follower position is the same as the relationship between the rotation angle of the operating lever 70 centered on the shaft 64 and the press-in distance of the contact 81 along the direction of the axis Q when the follower 76 moves from the second follower position to the reference follower position. By forming the cam groove 56 into such a shape, the user can perform the operation of moving the operating lever 50 from the first operating lever position to the opening direction (opening operation) and the operation of moving the operating lever 50 from the second operating lever position to the closing direction (closing operation) in the same manner with the same force, and the user's operating feeling of the operating lever 50 can be improved.

[0070] For example, consider the cam groove of the operating lever 50 as Fig.11As shown in FIG. 1 , the cam groove 156 extends linearly from the inner portion 156A to the outer portion 156B. When the small diameter portion 78 of the follower portion 76 of the operating rod 70 moves along such a cam groove 156, if the relationship between the rotation angle of the operating rod 70 relative to the first operating rod position and the pressed distance of the contact 81 along the axis Q is obtained by simulation, it is as follows: Fig.12 As shown.

[0071] Depend on Fig.12 It can be seen that in the case of the cam groove 156 extending in a straight line, when the operating lever 70 rotates from the first operating lever position to the second operating lever position (opening operation of the operating lever 50), the pressing distance of the contact 81 increases gradually (region A), and the force acting on the operating lever 70 and the operating lever 50 from the coil spring 82 also increases gradually. On the other hand, when the operating lever 70 rotates from the second operating lever position to the first operating lever position (closing operation of the operating lever 50), the pressing distance of the contact 81 increases sharply (region B), and the force acting on the operating lever 70 and the operating lever 50 from the coil spring 82 also increases sharply. This means that there is a difference in the force for operating the operating lever 50 between the opening operation and the closing operation of the operating lever 50, and there is a difference in the operating feel of the operating lever 50.

[0072] The cam groove 56 described above improves the shape of the cam groove 156 so that such a force difference does not occur, and the operating lever 50 can be operated with the same operating feeling in any action. Figure 5B and Figure 5C As shown, the cam groove 56 is composed of a first groove portion 58A extending along a line connecting the inner portion 56A and the outer portion 56B, a second groove portion 58B connected to the first groove portion 58A and extending in a manner that the change in the radial direction relative to the circumferential direction is smaller than that of the first groove portion 58A, and a third groove portion 58C connected to the second groove portion 58B and extending in a manner that the change in the radial direction relative to the circumferential direction is larger than that of the first groove portion 58A and the second groove portion 58B. The first groove portion 58A coincides with a part of the above-mentioned cam groove 156.

[0073] Fig.13 The figure shows the relationship between the rotation angle of the working rod 70 relative to the first working rod position and the press-in distance of the contact 81 along the axis Q when the cam groove 56 is used. The small diameter portion 78 of the follower portion 76 of the working rod 70 corresponds to the area C while moving in the third groove portion 58C, corresponds to the area D while moving in the second groove portion 58B, and corresponds to the area E while moving in the first groove portion 58A.

[0074] The shape of the third groove portion 58C is designed so that the change in the press-in distance of the contact 81 in the region C is symmetrical with respect to the center of the rotation angle range of the operating rod 70 and the change in the press-in distance of the contact 81 in the region E (or the change in the press-in distance of the contact 81 in the region B). In addition, the shape of the second groove portion 58B is designed so that the press-in distance of the contact 81 is constant. By making the cam groove 56 have such a shape, the change in the force applied to the operating rod 50 from the coil spring 82 during the opening action of the operating rod 50 is consistent with the change in the force applied to the operating rod 50 from the coil spring 82 during the closing action of the operating rod 50, so that the user can perform the opening action and the closing action of the operating rod 50 with the same operation feeling.

[0075] The shape of the cam groove 56 in the present embodiment is merely an example, and may be any shape as long as the relationship between the rotation angle of the working rod 70 and the moving distance (pressing distance) of the contact 81 during the opening action of the operating rod 50 and the relationship between the rotation angle of the working rod 70 and the moving distance (pressing distance) of the contact 81 during the closing action of the operating rod 50 are the same.

[0076] In the present embodiment, the follower 76 is divided into the large diameter portion 77 pressed by the contact 81 and the small diameter portion 78 moving in the cam groove 56 of the operating lever 50 . However, the large diameter portion 77 and the small diameter portion 78 may be integrated.

[0077] As described above, in the present embodiment, the cam groove 56 of the operating lever 50 and the follower 76 of the working lever 70 constitute a cam mechanism that converts the movement of the operating lever 50 in the circumferential direction into the rotation of the working lever 70 about the shaft 64. Such a cam mechanism is not limited to the example shown in the figure, and for example, a cam groove corresponding to the cam groove 56 may be provided on the working lever 70, and a follower corresponding to the follower 76 may be provided on the operating lever 50, and the cam groove of the working lever 70 and the follower of the operating lever 50 may constitute a cam mechanism.

[0078] In addition, the switch 30 in the above embodiment is used to switch the aperture blades 21 to 23 between the aperture position and the open position, but it is not limited to this. As long as it is a switch that switches between two switching states, it can be used for any purpose. For example, the switch 30 can also be used to drive blades other than the aperture blades 21 to 23. In addition, the camera device 1 in the above embodiment uses three aperture blades 21 to 23 to generate vignetting in the captured image, but the number of such aperture blades is not limited to three, as long as at least one aperture blade is provided.

[0079] In addition, the switch 30 can also be used in devices other than the camera device 1. In various fields, a sliding switch is often used in which an operating rod slides linearly. When the operating rod slides linearly, the structure of the switch can be relatively simple. However, when the operating rod needs to slide in the circumferential direction, the structure of the switch tends to become complicated. Therefore, if the above-mentioned switch 30 is applied to a device that needs to slide the operating rod in the circumferential direction, the switching state can be easily switched with a simple structure.
