Description

camera equipment

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

[0002] Conventionally, cameras have been known that have a door that opens and closes an opening for inserting and removing a photographic film pack or the like (see, for example, Patent Document 1). Such a door is connected to the camera body via a hinge mechanism that includes a shaft, and the door can rotate around the shaft of the hinge mechanism.

[0003] Japanese Patent Application Laid-Open No. 2024-346

[0004] Generally, the shaft of such a hinge mechanism is fixed to either the camera body or the door by press-fitting. However, such shafts are often thin and short, making it difficult to press-fit the shaft into the camera body or door. Furthermore, the shaft may need to be removed when disassembling the camera to replace or repair internal parts, but once pressed-fit, it is difficult to remove the shaft.

[0005] SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and has as its object to provide a camera whose door section can be easily assembled and disassembled.

[0006] According to one aspect of the present invention, there is provided a camera device comprising: a casing having at least one shaft and at least one fixed-side bearing portion that rotatably supports the at least one shaft; and a door portion that is rotatable around the at least one shaft relative to the casing, wherein the door portion has a door body including at least one rotating-side bearing portion that rotatably supports the at least one shaft and a groove portion that accommodates an end of the at least one shaft extending beyond the at least one rotating-side bearing portion; a body covering portion that covers at least a portion of an outer surface of the door body; and an outer cover that includes a groove insert portion that is inserted into the groove portion of the door body, wherein the groove insert portion of the outer cover has a restricting portion that contacts the end of the at least one shaft within the groove portion of the door body to restrict axial movement of the at least one shaft.

[0007] According to the present invention, when attaching the door section to the casing, the shaft is moved axially from the groove in the door body and inserted into the rotation-side bearing section and the fixed-side bearing section, and then the groove insertion section of the outer cover is inserted into the groove in the door body, so that the axial movement of the shaft is restricted by the restricting section of the groove insertion section of the outer cover, and the shaft can be fixed to the rotation-side bearing section and the fixed-side bearing section. In addition, by removing the outer cover from the door body, the shaft can be moved axially, and the door section can be easily removed from the casing.

[0009] Hereinafter, an embodiment of a camera device according to the present invention will be described in detail with reference to FIGS. 1 to 21. In FIGS. 1 to 21, identical or corresponding components are designated by the same reference numerals, and redundant description will be omitted. In addition, in FIGS. 1 to 21, the scale and dimensions of each component may be exaggerated, and some components may be omitted. In the following description, unless otherwise specified, terms such as "first" and "second" are used merely to distinguish components from one another, and do not represent a specific order or ranking.

[0010] Overview of the Camera Device Figure 1 is a front perspective view of a camera device 1 according to one embodiment of the present invention, and Figure 2 is a rear perspective view. The camera device 1 in this embodiment is a camera (instant camera) that uses photographic film that is automatically developed after photography, but it goes without saying that the present invention can be applied to devices other than instant cameras. Note that in this embodiment, for convenience, the direction from the camera device 1 along the optical axis direction toward the subject (the +Z direction in Figure 1) will be referred to as "front" or "forward," and the direction from the subject toward the camera device 1 (the -Z direction) will be referred to as "rear" or "rearward."

[0011] As shown in Figures 1 and 2, the camera device 1 includes a front cover 2, a rear cover 3 arranged adjacent to and behind the front cover 2, side covers 4 and 5 attached to the sides of the front cover 2 and the rear cover 3, a film ejection cover 6 arranged between the front cover 2 and the rear cover 3, a door portion 7 attached to the rear of the rear cover 3, a lens barrel 8 housing a lens unit therein, and an operation ring 9 rotatably arranged around the lens barrel 8 for operating the retraction and extension of the lens barrel 8.

[0012] A viewfinder window 10 and a release button 11 are provided on the front surface of the side cover 4, and a viewfinder section 12 is provided on the rear surface of the side cover 4, allowing the user to observe an image of a subject in front through the viewfinder window 10. A flash 13 is also provided between the front cover 2 and the side cover 4. The film exit cover 6 has an exit port 6A extending in the X direction, and the developed photographic film is discharged from this exit port 6A after exposure.

[0013] In the example shown in Figures 1 and 2, the casing of the camera device 1 is made up of a front cover 2, a rear cover 3, side covers 4 and 5, and a film ejection cover 6, and a roughly rectangular parallelepiped frame 20 shown in Figure 3 is housed inside this casing. A film storage space S capable of storing photographic film (not shown) containing a developing solution is formed inside this frame 20. A rectangular opening 21 is formed in the front of the frame 20. The lens barrel 8 shown in Figure 1 is located in front of this frame 20. Therefore, light that passes through the optical system of the lens barrel 8 is incident on the photographic film in the film storage space S through the opening 21 formed in the frame 20.

[0014] Film Eject Cover First, the film eject cover 6 and the components related to the film eject cover 6 will be described in more detail. FIG. 4 is a partial vertical cross-sectional view of the camera device 1 including the film eject cover 6. As shown in FIGS. 3 and 4, the frame 20 includes a film ejection section 22 that ejects photographic film exposed during photography in the transport direction (+Y direction). A fiber member 23 extending in the X direction is disposed at the +Y end of the film ejection section 22. This fiber member 23 has a slit 23A extending in the X direction for allowing the photographic film to pass through. This fiber member 23 is formed from a fabric such as felt. The film ejection cover 6 is located on the +Y side of the film ejection section 22. Protrusions 24 and 25 protruding in the +Y direction are provided at approximately the center of the film ejection section 22 in the X direction.

[0015] A pair of rollers 26 is disposed on the -Y side of the film discharge section 22, and the exposed photographic film is pushed from both sides by the pair of rollers 26 while being sent out in the transport direction (+Y direction). The pressure from the rollers 26 causes the contained developer to spread within the photographic film, and the photographic film is developed. The photographic film sent out in the transport direction (+Y direction) by the rollers 26 passes through the slits 23A in the fiber member 23 and is discharged to the outside of the camera device 1 through the discharge opening 6A in the film discharge cover 6.

[0016] Figure 5A is a plan view of the film ejection cover 6, Figure 5B is a front view, and Figure 5C is a left side view. As shown in Figures 5A to 5C, the film ejection cover 6 has a lip portion 30 extending in the Y direction in an oval cylindrical shape, an extension portion 31 extending outward from the lip portion 30 near the frame 20, a first hook portion 32 extending in the +Z direction from approximately the center of the lip portion 30 in the X direction, a second hook portion 33 extending in the -Z direction from approximately the center of the lip portion 30 in the X direction, and a pair of guide pieces 34 extending in the -Z direction from both ends of the extension portion 31 in the X direction. The hook portions 32 and 33 are each elastically deformable in the Y direction. As shown in Figures 1 and 2, the +Y direction end 30A of the lip portion 30 is exposed to the outside.

[0017] 4, the first hook portion 32 of the film discharge cover 6 engages with the protrusion 24 of the film discharge portion 22 in the -Z direction, and the second hook portion 33 engages with the protrusion 25 of the film discharge portion 22 in the +Z direction. This engagement fixes the film discharge cover 6 to the film discharge portion 22 (frame 20) in the Z direction.

[0018] When assembling the camera device 1, the rear cover 3 is fixed to the frame 20, and then the film exit cover 6 is attached to the rear cover 3. Figure 6 is a cross-sectional view that schematically shows the attached state of the film exit cover. As shown in Figure 6, the rear cover 3 has a pair of guide surfaces 40 that extend along the YZ plane. These guide surfaces 40 are located on the +X side and the -X side of the film exit cover 6, respectively, and the film exit cover 6 is held between these guide surfaces 40.

[0019] FIG. 7 is a vertical cross-sectional view schematically illustrating the process of attaching the film ejection cover 6 to the rear cover 3. As shown in FIG. 7, the rear cover 3 has an upper surface portion 41 adjacent to the lip portion 30 of the film ejection cover 6 and a protrusion 42 extending parallel to the upper surface portion 41 on the −Y direction side of the upper surface portion 41. An insertion space G into which the guide piece 34 of the film ejection cover 6 is inserted is formed between the upper surface portion 41 and the protrusion 42. The height of this insertion space G in the Y direction is approximately the same as the thickness of the guide piece 34 of the film ejection cover 6 in the Y direction. The film ejection cover 6 is held on the rear cover 3 by inserting the guide piece 34 of the film ejection cover 6 into this insertion space G in the −Z direction (attachment direction). In this manner, the upper surface portion 41 and the protrusion 42 of the rear cover 3 in this embodiment function as a holding portion that sandwiches and holds the guide piece 34 of the film ejection cover 6.

[0020] As described above, when attaching the film ejection cover 6 to the rear cover 3, the guide piece 34 of the film ejection cover 6 is inserted in the -Z direction into the insertion space G of the rear cover 3, as shown in Fig. 7. At this time, because the guide surface 40 of the rear cover 3 adjacent to the guide piece 34 of the film ejection cover 6 extends along the Z direction (attachment direction), as shown in Fig. 6, the guide piece 34 of the film ejection cover 6 is inserted into the insertion space G between the top surface portion 41 and the protrusion 42 while being guided inside the guide surface 40 of the rear cover 3. Therefore, the film ejection cover 6 can be easily attached to the rear cover 3.

[0021] When the film ejection cover 6 is inserted in the -Z direction toward the rear cover 3 in this way, the second hook portion 33 elastically deforms and eventually rides over and engages with the protrusion 25 of the film ejection section 22. This stably fixes the film ejection cover 6 in the Z direction to the rear cover 3 and the frame 20. At this time, as shown in Figure 4, a space is formed between the top surface portion 41 of the rear cover 3 and the second hook portion 33 of the film ejection cover 6 so that the second hook portion 33 can elastically deform.

[0022] In this type of film ejection cover 6, the rigidity of the film ejection cover 6 can be ensured by greatly extending the extension portion 31 from the lip portion 30, so that the width of the lip portion 30 exposed to the outside of the film ejection cover 6 can be narrowed while suppressing deformation of the film ejection cover 6. Therefore, the width of the lip portion 30 can be narrowed while suppressing deformation of the film ejection cover 6, thereby improving aesthetics. In addition, because the first hook portion 32 and the second hook portion 33 engage with the frame 20 from both sides in the Z direction, the film ejection cover 6 can be stably fixed to the frame 20 in the Z direction.

[0023] After the film ejection cover 6 is attached to the rear cover 3 as described above, the front cover 2 is attached to the frame 20. As shown in FIG. 4 , the front cover 2 attached to the frame 20 contacts the extension portion 31 of the film ejection cover 6 at the top surface 2A adjacent to the lip portion 30 of the film ejection cover 6. The photographic film fed in the +Y direction from the roller 26 may come into contact with the film ejection cover 6 during transport. In such a case, contact with the photographic film may cause the film ejection cover 6 to move in the +Y direction, resulting in rattle. In this embodiment, because the top surface 2A of the front cover 2 contacts the extension portion 31 of the film ejection cover 6 as described above, even if the photographic film comes into contact with the film ejection cover 6, the top surface 2A of the front cover 2 restricts the movement of the film ejection cover 6 in the +Y direction, thereby reducing rattle when the photographic film is ejected. In this embodiment, the upper surface 41 of the rear cover 3 also contacts the extension 31 of the film ejection cover 6, but it is sufficient that at least one of the front cover 2 and the rear cover 3 contacts the extension 31 of the film ejection cover 6.

[0024] In the illustrated example, the hook portions 32, 33 of the film discharge cover 6 extend in the Z direction from the extension portion 31, but the hook portions 32, 33 may extend in a direction perpendicular to the transport direction (+Y direction) in which the photographic film is transported. For example, the hook portions 32, 33 may extend in the X direction from the extension portion 31 and engage with the film discharge portion 22 in the X direction. Furthermore, in order to stably fix the position of the film discharge cover 6 relative to the film discharge portion 22, it is preferable that the first hook portion 32 and the second hook portion 33 extend in opposite directions and that the hook portions 32, 33 engage with the film discharge portion 22 from both sides.

[0025] Furthermore, in this embodiment, the first hook portion 32 of the film exit cover 6 engages with the frame 20 (the protrusion 24 of the film exit portion 22), but the first hook portion 32 may engage with the front cover 2. Similarly, the second hook portion 33 of the film exit cover 6 engages with the frame 20 (the protrusion 25 of the film exit portion 22), but the second hook portion 33 may engage with the rear cover 3. That is, the first hook portion 32 may engage with the front cover 2 and the second hook portion 33 may engage with the rear cover 3, or the first hook portion 32 may engage with the front cover 2 and the second hook portion 33 may engage with the frame 20, or the first hook portion 32 may engage with the frame 20 and the second hook portion 33 may engage with the rear cover 3.

[0026] In this embodiment, the hook portions 32, 33 of the film exit cover 6 are located near the center along the longitudinal direction (X direction) of the exit port 6A. Since the central portion of the film exit cover 6 along the longitudinal direction of the exit port 6A is most susceptible to deformation in the Z direction, providing at least one of the hook portions 32, 33 near the center along the longitudinal direction of the exit port 6A and fixing it to the frame 20 in this manner can effectively suppress deformation of the portion most susceptible to deformation. It goes without saying that the positions of the hook portions 32, 33 are not limited to near the center along the longitudinal direction of the exit port 6A.

[0027] 5B and 5C, the film ejection cover 6 in this embodiment has a pair of protrusions 35 that protrude in the -Y direction at both ends in the X direction of the extension section 31. By providing such protrusions 35, even if the film ejection cover 6 unintentionally moves in the -Y direction, the protrusions 35 come into contact with the upper surface of the film ejection section 22, making it possible to restrict the movement of the film ejection cover 6 to a certain range.

[0028] In this embodiment, the film exit cover 6 is attached to the rear cover 3, so the rear cover 3 is provided with the guide surface 40 and the protrusion 42, but it is also possible to attach the film exit cover 6 to the front cover 2. In this case, elements corresponding to the guide surface 40 and the protrusion 42 of the rear cover 3 can be provided on the front cover 2.

[0029] As described above, the camera device 1 in this embodiment includes the front cover 2 and rear cover 3 arranged adjacent to each other, a frame 20 having a film storage space S for storing photographic film therein, and a film exit cover 6 arranged between the front cover 2 and the rear cover 3 and having an exit port 6A through which photographic film passes as it is ejected from the film storage space S in the transport direction (+Y direction). The film exit cover 6 extends in the transport direction (Y direction) and has a lip portion 30 with an end 30A exposed to the outside, an extension portion 31 that extends outward from the lip portion 30 near the frame 20, a first hook portion 32 that engages with the frame 20 (or one of the front cover 2 and the rear cover 3) in a first direction (-Z direction) perpendicular to the transport direction, and a second hook portion 33 that engages with the frame 20 (or the other of the front cover 2 and the rear cover 3) in a second direction (+Z direction) opposite to the first direction. With this configuration, the rigidity of the film ejection cover 6 can be ensured by greatly expanding the extension portion 31 of the film ejection cover 6 from the lip portion 30, so deformation of the film ejection cover 6 can be suppressed, the photographic film can be ejected without being damaged, and the width of the lip portion 30 exposed to the outside of the film ejection cover 6 can be narrowed to improve aesthetics. Furthermore, because the first hook portion 32 and the second hook portion 33 engage with the frame 20 from both sides in the direction perpendicular to the transport direction of the photographic film, the film ejection cover 6 can be stably fixed to the frame 20 in the Z direction.

[0030] Furthermore, by positioning at least one of the first hook portion 32 and the second hook portion 33 (both in the illustrated example) near the center along the longitudinal direction of the discharge opening 6A, deformation of the part of the film discharge cover 6 that is most susceptible to deformation can be effectively suppressed.

[0031] Furthermore, since the film discharge cover 6 has a protrusion 35 that protrudes from the extension section 31 toward the frame 20 (film discharge section 22), even if the film discharge cover 6 unintentionally moves toward the frame 20, the protrusion 35 will come into contact with the film discharge section 22, so the movement of the film discharge cover 6 can be restricted within a certain range.

[0032] Furthermore, the rear cover 3 has a pair of guide surfaces 40 that extend along an attachment direction perpendicular to the transport direction (Y direction), and the film exit cover 6 has a pair of guide pieces 34 that extend from the extension portion 31 along the attachment direction and are guided inside the pair of guide surfaces 40. Therefore, when attaching the film exit cover 6 to the rear cover 3, the guide pieces 34 of the film exit cover 6 are guided inside the guide surfaces 40 of the rear cover 3, so that the film exit cover 6 can be easily attached to the rear cover 3.

[0033] Furthermore, the rear cover 3 has an upper surface portion 41 and a protrusion portion 42 as holding portions that sandwich and hold the pair of guide pieces 34 of the film ejection cover 6, so that the film ejection cover 6 can be firmly fixed to the rear cover 3.

[0034] Furthermore, since the extension portion 31 of the film discharge cover 6 is configured to come into contact with the upper surface portion 2A of the front cover 2, even if the photographic film being discharged through the discharge opening 6A comes into contact with the film discharge cover 6, the upper surface portion 2A of the front cover 2 restricts the movement of the film discharge cover 6 in the transport direction, thereby reducing rattling when the photographic film is discharged.

[0035] Next, the side cover 5 and the components related to the side cover 5 will be described in more detail. As shown in Figures 1 and 2, a decorative plate 50 is attached to the side cover 5. The side cover 5 covers a portion of the frame 20, and in this embodiment, it covers the side portion of the frame 20 on the +X direction side. The decorative plate 50 is intended to enhance the aesthetic appeal of the side cover 5.

[0036] FIG. 8 is an exploded perspective view of the side cover 5 and the decorative plate 50 shown in FIG. 2 , and FIG. 9 is a perspective view of the decorative plate 50. As shown in FIG. 8 , the side cover 5 has a recess 60 recessed toward the −X direction, and the decorative plate 50 is disposed within this recess 60. The recess 60 has a circular hole 61 for inserting a screw 65 serving as a fastener for fixing the side cover 5 to the frame 20. The side cover 5 is fixed to the frame 20 by inserting the screw 65 into the circular hole 61 and fastening the screw 65 to the screw hole 27 (see FIG. 3 ) of the frame 20. Furthermore, a plurality of hook holes 62 are formed near the outer edge of the recess 60. In this embodiment, six hook holes 62 are formed in the recess 60. Furthermore, two positioning holes 63 are formed in the recess 60. Furthermore, the recess 60 has a tool insertion hole 64 for inserting a rod-shaped tool (not shown), as described below.

[0037] As shown in FIG. 9 , the decorative plate 50 includes a plate body 51, multiple hook portions 52 extending in the −X direction from near the outer edge of the plate body 51, and two protrusions 53 protruding from the plate body 51 in the −X direction. Each hook portion 52 is elastically deformable in the Z direction. The hook portions 52 of the decorative plate 50 are provided to correspond to the hook holes 62 of the side cover 5, and the decorative plate 50 is fixed to the side cover 5 by engaging the hook portions 52 of the decorative plate 50 with the hook holes 62 of the side cover 5. The protrusions 53 of the decorative plate 50 are provided to correspond to the positioning holes 63 of the side cover 5, and by positioning the protrusions 53 of the decorative plate 50 in the positioning holes 63 of the side cover 5, the decorative plate 50 can be positioned correctly in the recess 60 of the side cover 5.

[0038] 8, in this embodiment, the holes 61 to 64 and the screws 65 formed in the side cover 5 are covered by the plate body 51 of the decorative plate 50. Therefore, these holes 61 to 64 and the screws 65 are not exposed to the outside, improving the aesthetic appeal of the side cover 5. To further improve the aesthetic appeal, for example, the outer surface of the decorative plate 50 may be subjected to a leather grain finish.

[0039] Returning to Figure 3, the frame 20 has a tool insertion hole 28 formed therein so as to be coaxial with the tool insertion hole 64 formed in the recess 60 of the side cover 5. Figure 10 is a partial cross-sectional view including the tool insertion holes 64, 28 of the side cover 5 and the frame 20. As shown in Figure 10, in this embodiment, a portion of the rear cover 3 is located between the side cover 5 and the frame 20, and this rear cover 3 also has a tool insertion hole 71 formed therein so as to be coaxial with the tool insertion hole 64 formed in the recess 60 of the side cover 5.

[0040] Therefore, with the decorative plate 50 fitted into the recess 60 of the side cover 5, i.e., with the hook portion 52 of the decorative plate 50 engaged with the hook hole 62 of the side cover 5, a rod-shaped tool such as a thin hex wrench can be inserted in the +X direction from the tool insertion hole 28 of the frame 20 into the tool insertion hole 71 of the rear cover 3 and the tool insertion hole 64 of the side cover 5. Therefore, the rod-shaped tool inserted into the tool insertion holes 28, 71, 64 in this manner can push the decorative plate 50 outward (in the +X direction) from the frame 20 side. This causes the hook portion 52A (see FIGS. 8 and 9 ), which is the hook portion 52 of the decorative plate 50 that is closest to the tool insertion hole 64, to elastically deform, thereby disengaging the hook portion 52A from the hook hole 62 of the side cover 5. When the hook portion 52A of the decorative plate 50 disengages from the hook hole 62 of the side cover 5, the vicinity of the hook portion 52A of the plate body 51 is lifted from the side cover 5, and a tool can be inserted between the plate body 51 and the side cover 5 through the gap created in this lifted portion, and this tool can be used to sequentially disengage the other hook portions 52 from the outside of the side cover 5. By disengaging all of the hook portions 52 in this way, the decorative plate 50 can be easily removed from the side cover 5.

[0041] When the side cover 5 needs to be removed from the frame 20 after assembling the camera device 1 to replace or repair internal components of the camera device 1, as described above, the decorative plate 50 can be removed from the side cover 5 by inserting a rod-shaped tool through the tool insertion hole 28 of the frame 20 and pushing the decorative plate 50 outward to disengage the hook portions 52A, and then disengaging the other hook portions 52 from the outside of the side cover 5. Furthermore, the side cover 5 can be removed from the frame 20 by loosening the screws 65 exposed in the recesses 60 of the side cover 5. As described above, according to this embodiment, the aesthetic appearance can be improved by hiding the screws 65 and hook holes 62 that secure the side cover 5 to the frame 20 with the decorative plate 50. Furthermore, when disassembly of the camera device 1 becomes necessary, the decorative plate 50 can be easily removed from the side cover 5 by inserting a rod-shaped tool through the tool insertion hole 28 of the frame 20.

[0042] 10 , a cylindrical guide wall 72 is formed around the tool insertion hole 71 of the rear cover 3, extending in the direction in which the tool is inserted, i.e., the X direction. When an operator inserts a tool from the frame 20 side, the operator cannot see the +X direction side from the tool insertion hole 28 of the frame 20, so it is conceivable that the tool will be inserted in an unintended direction and will not be able to be properly inserted into the tool insertion hole 71 of the rear cover 3 and the tool insertion hole 64 of the side cover 5. However, in this embodiment, the tool inserted through the tool insertion hole 28 of the frame 20 is guided by the guide wall 72 to the tool insertion hole 71 of the rear cover 3, making it possible to easily insert the tool into the tool insertion hole 71 of the rear cover 3 and the tool insertion hole 64 of the side cover 5. Note that such a guide wall 72 may be provided on the frame 20 or the side cover 5.

[0043] Here, the tool insertion hole 64 of the side cover 5 described above is preferably located further outward than the outermost hook hole 62 of the multiple hook holes 62 in the longitudinal direction (Y direction in this embodiment) of the decorative plate 50. That is, as shown in FIG. 11 , the tool insertion hole 64 of the side cover 5 is preferably located in a region P1 further to the -Y direction side than the hook holes 62A, 62B located furthest to the -Y direction, or in a region P2 further to the +Y direction side than the hook holes 62C, 62D located furthest to the +Y direction. By locating the tool insertion hole 64 of the side cover 5 in region P1 or P2, it is possible to increase the force acting on the hook portion 52 located outermost in the longitudinal direction of the decorative plate 50 when the decorative plate 50 is pressed with a tool through the tool insertion hole 64. This allows the engagement between the hook portion 52 and the hook hole 62 to be disengaged with less force, making it easier to remove the decorative plate 50.

[0044] If there is a possibility that external light may enter the photographic film in the film storage space S through the tool insertion holes 28, 64, 71, it is preferable to position the tool insertion holes 28, 64, 71 outside the shooting area of ​​the camera device 1 or to cover the tool insertion holes 28, 64, 71 with light-shielding tape.

[0045] As described above, the camera device 1 of this embodiment includes a frame 20 having a film storage space S for storing photographic film therein, a side cover 5 covering at least a portion of the frame 20 and having a plurality of hook holes 62, screws 65 (fixing devices) for securing the side cover 5 to the frame 20, and a decorative plate 50 having a plurality of hook portions 52 that engage with the hook holes 62 of the side cover 5 and covering the screws 65 and the hook holes 62. The frame 20 and the side cover 5 also have tool insertion holes 28, 64 for inserting a tool that pushes the decorative plate 50 outward from the frame 20 side to disengage at least one of the plurality of hook portions 52 from the hook holes 62. This configuration enhances aesthetics by hiding the screws 65 and hook holes 62 that secure the side cover 5 to the frame 20 with the decorative plate 50. Furthermore, because the screws 65 are hidden by the decorative plate 50, the screws 65 will not come loose and fall off. Furthermore, when it becomes necessary to disassemble the camera device 1, the decorative plate 50 can be easily removed from the side cover 5 by inserting a rod-shaped tool into the tool insertion hole 64 through the tool insertion hole 28 of the frame 20.

[0046] Furthermore, by positioning the tool insertion holes 28, 64 further outward than the hook holes 62A, 62B, 62C, 62D that are located outermost in the longitudinal direction of the decorative plate 50 among the multiple hook holes 62, it is possible to increase the force acting on the outermost hook portion 52 in the longitudinal direction of the decorative plate 50 when the decorative plate 50 is pressed with a tool through the tool insertion holes 28, 64. Therefore, the engagement between the hook portion 52 and the hook hole 62 can be released with less force, making it easier to remove the decorative plate 50.

[0047] Furthermore, in this embodiment, the rear cover 3 has guide walls 72 that extend around the tool insertion hole 71 in the direction in which the tool is inserted, so that a tool inserted through the tool insertion hole 28 of the frame 20 is guided by the guide walls 72 to the tool insertion hole 71 of the rear cover 3, making it possible to easily insert the tool into the tool insertion hole 71 of the rear cover 3 and the tool insertion hole 64 of the side cover 5.

[0048] In addition, the side cover 5 has a positioning hole 63, and the decorative plate 50 has a protrusion 53 that is inserted into the positioning hole 63 of the side cover 5. Therefore, by positioning the protrusion 53 of the decorative plate 50 within the positioning hole 63 of the side cover 5, the decorative plate 50 can be placed in the correct position within the recess 60 of the side cover 5.

[0049] Door Section Next, the door section 7 and the components related to the door section 7 will be described in more detail. The door section 7 is rotatably attached to the rear cover 3, and the door section 7 shown in FIG. 2 is locked in a closed state in close contact with the rear cover 3 by a locking mechanism (not shown). Hereinafter, the state shown in FIG. 2 will be referred to as the closed state. When an unlock button 43 provided on the rear cover 3 is pressed from this closed state, the locking mechanism is released and the door section 7 can be rotated to the state shown in FIG. 12. Hereinafter, the state shown in FIG. 12 will be referred to as the open state. Note that the coordinate systems in all of the figures from FIG. 13 onwards are based on the closed state.

[0050] The structure for rotatably supporting the door section 7 will be described in more detail. Fig. 13 is an enlarged perspective view of a portion of the camera device 1 including the rotation support structure for the door section 7, and Fig. 14 is an exploded perspective view of the door section 7 and the rear cover 3. As shown in Figs. 13 and 14, the rear cover 3 of this embodiment has a bearing 45A (first fixed-side bearing) that rotatably supports a shaft 80A (first shaft) extending in the X direction, and a bearing 45B (second fixed-side bearing) that rotatably supports a shaft 80B (second shaft) extending coaxially with the shaft 80A in the X direction. The door section 7 also includes a door main body 81, an outer cover 82 attached to the outside of the door main body 81, and an inner cover 83 (see Fig. 12) attached to the inside of the door main body 81.

[0051] FIG. 15 is a rear view showing the configuration of the door section 7 excluding the outer cover 82, and FIG. 16 is a cross-sectional view taken along line A-A in FIG. 15. As shown in FIGS. 15 and 16, the door main body 81 includes a shaft holding portion 85A that holds one end of the shaft 80A supported by the bearing portion 45A of the rear cover 3, a shaft holding portion 86A that holds the other end of the shaft 80A, a shaft holding portion 85B that holds one end of the shaft 80B that is supported by the bearing portion 45B of the rear cover 3, and a shaft holding portion 86B that holds the other end of the shaft 80B. A notch 87A for locating the bearing portion 45A of the rear cover 3 is formed between the shaft holding portions 85A and 86A, and a notch 87B for locating the bearing portion 45B of the rear cover 3 is formed between the shaft holding portions 85B and 86B. In addition, a groove 88 extending along the X direction is formed between the shaft holding portions 86A and 86B of the door main body 81. In this manner, the shaft holding portions 85A and 86A in this embodiment function as bearing portions (first rotation-side bearing portions) that rotatably support the shaft 80A, and the shaft holding portions 85B and 86B function as bearing portions (second rotation-side bearing portions) that rotatably support the shaft 80B. The bearing portions 85A, 86A, 85B, and 86B of the door main body 81 and the bearing portions 45A and 45B of the rear cover 3 enable the door portion 7 to rotate about the shafts 80A and 80B (rotation axes) relative to the rear cover 3.

[0052] Fig. 17A is a perspective view showing the outer cover 82, Fig. 17B is a plan view, and Fig. 17C is a right side view. As shown in Figs. 17A to 17C, the outer cover 82 has a body covering portion 90 that curves along the outer surface 81A of the door body 81 and covers the outer surface 81A of the door body 81, a groove insertion portion 91 that protrudes in the +Z direction from one edge of the body covering portion 90, and two mounting protrusions 92 that protrude in the +Z direction near the other edge of the body covering portion 90. As shown in Fig. 15, two mounting holes 84 that receive the mounting protrusions 92 of the outer cover 82 are formed in the outer surface 81A of the door body 81. The groove insertion portions 91 of the outer cover 82 are shaped so as to be insertable into the grooves 88 of the door body 81, and the outer cover 82 is attached to the door body 81 by inserting the groove insertion portions 91 of the outer cover 82 into the grooves 88 of the door body 81 and inserting the mounting protrusions 92 of the outer cover 82 into the mounting holes 84 of the door body 81. As described above, the groove insertion portions 91 in this embodiment serve to fix the outer cover 82 to the door body 81, in addition to the role of fixing the shafts 80A and 80B, which will be described later. The outer cover 82 and the outer surface 81A of the door body 81 may be bonded together using double-sided tape or the like.

[0053] 17A to 17C, the groove insertion portion 91 of the outer cover 82 includes a central portion 93 and shoulder portions 94 located on both sides of the central portion 93 in the X direction. The height of the central portion 93 in the Z direction is greater than the height of the shoulder portions 94 in the Z direction. The groove insertion portion 91 extends in the X direction by a length substantially equal to the length L1 (see FIG. 15) of the groove portion 88 of the door main body 81 in the X direction.

[0054] FIG. 18 is a cross-sectional view of the camera device 1 shown in FIG. 1 taken along line A-A in FIG. 15. As shown in FIG. 18, shaft 80A extends in the negative X direction beyond shaft holder 86A of door body 81, with end 801A positioned within groove 88 of door body 81. Similarly, shaft 80B extends in the positive X direction beyond shaft holder 86B of door body 81, with end 801B positioned within groove 88. Here, the length L2 (see FIG. 17B ) along the X direction of center portion 93 of groove insertion portion 91 of outer cover 82 is approximately equal to the distance between end 801A of shaft 80A and end 801B of shaft 80B. Therefore, when shaft 80A or 80B attempts to move in the axial direction, end 801A or 801B of shaft 80A or 80B contacts center portion 93 of groove insertion portion 91, restricting the axial movement of shaft 80A or 80B. This prevents the shafts 80A and 80B from coming off the bearing portions 85A, 86A, 85B, and 86B of the door body 81 and the bearing portions 45A and 45B of the rear cover 3. In this manner, the central portion 93 of the groove insertion portion 91 in this embodiment comes into contact with the end portions 801A and 801B of the shafts 80A and 80B within the groove portion 88 of the door body 81, and serves as a restricting portion that restricts the axial movement of the shafts 80A and 80B.

[0055] Furthermore, the shoulder 94 of the groove insertion portion 91 is located radially outward of the shafts 80A, 80B in the groove 88 of the door body 81, and this shoulder 94 prevents the shafts 80A, 80B from being seen from the outside. In this manner, the shoulder 94 of the groove insertion portion 91 in this embodiment serves as a shaft covering portion located radially outward of the shafts 80A, 80B inside the groove 88 of the door body 81.

[0056] When attaching the door section 7 to the rear cover 3, first, as shown in Fig. 19A , the door main body 81 is moved so that the bearings 45A and 45B of the rear cover 3 are positioned in the cutouts 87A and 87B of the door main body 81, respectively. That is, the shaft holding portions 85A, 86A, 85B, and 86B of the door main body 81 are aligned with the bearings 45A and 45B of the rear cover 3. In this state, the shaft 80A is inserted into the groove 88 of the door main body 81, and then, as shown in Fig. 19B , the shaft 80A is moved in the +X direction from the groove 88 to insert the shaft 80A into the shaft holding portions 85A and 86A of the door main body 81 and the bearing 45A of the rear cover 3. Similarly, after inserting the shaft 80B into the groove 88 of the door body 81, as shown in FIG. 19B , the shaft 80B is moved from the groove 88 in the −X direction to insert the shaft 80B into the shaft holding portions 85B, 86B of the door body 81 and the bearing portion 45B of the rear cover 3. Thereafter, the groove insertion portion 91 of the outer cover 82 is inserted into the groove 88 of the door body 81, and the mounting protrusions 92 of the outer cover 82 are inserted into the mounting holes 84 of the door body 81, thereby attaching the outer cover 82 to the door body 81, resulting in the state shown in FIG. 18 . As a result, the center portions 93 of the groove insertion portions 91 of the outer cover 82 restrict the axial movement of the shafts 80A, 80B, so that the shafts 80A, 80B can be held in the shaft holding portions 85A, 86A, 85B, 86B of the door body 81 and the bearing portions 45A, 45B of the rear cover 3. Furthermore, assembly is easy because the shafts 80A and 80B can be inserted while the door body 81 is closed.

[0057] Furthermore, if it becomes necessary to disassemble the camera device 1, the shafts 80A, 80B can be easily removed from the shaft holding portions 85A, 86A, 85B, 86B of the door body 81 and the bearing portions 45A, 45B of the rear cover 3. That is, when the outer cover 82 is removed from the door body 81, the shafts 80A, 80B can be moved in the axial direction, and therefore, by moving the shafts 80A, 80B in the axial direction so as to be positioned within the groove portions 88 of the door body 81 and then removing the shafts 80A, 80B from the groove portions 88, the door body 81 can be easily removed from the rear cover 3.

[0058] As described above, the camera device 1 in this embodiment includes the shafts 80A, 80B, the rear cover 3 (casing) having bearings 45A, 45B (fixed-side bearings) that rotatably support the shafts 80A, 80B, and the door section 7 that is rotatable around the shafts 80A, 80B relative to the rear cover 3. The door section 7 includes a door main body 81 that includes bearings 85A, 86A, 85B, 86B (rotating-side bearings) that rotatably support the shafts 80A, 80B and grooves 88 that accommodate the ends 801A, 801B of the shafts 80A, 80B that extend beyond the bearings 85A, 86A, 85B, 86B, an outer cover 82 that includes a main body covering portion 90 that covers at least a portion of the outer surface 81A of the door main body 81 and a groove inserting portion 91 that is inserted into the groove 88 of the door main body 81. The groove insertion portions 91 of the outer cover 82 have central portions 93 (restricting portions) that contact the ends 801A, 801B of the shafts 80A, 80B in the grooves 88 of the door main body 81 and restrict axial movement of the shafts 80A, 80B. With this configuration, when attaching the door portion 7 to the rear cover 3, the shafts 80A, 80B are moved in the X direction from the grooves 88 of the door main body 81 to be inserted into the bearing portions 45A, 45B, 85A, 86A, 85B, and 86B, and then the groove insertion portions 91 of the outer cover 82 are inserted into the grooves 88 of the door main body 81. This restricts axial movement of the shafts 80A, 80B by the central portions 93 of the groove insertion portions 91 of the outer cover 82, thereby fixing the shafts 80A, 80B to the bearing portions 45A, 45B, 85A, 86A, 85B, and 86B. Therefore, the door portion 7 can be easily attached to the rear cover 3. Furthermore, by removing the outer cover 82 from the door body 81, the shafts 80A and 80B can be moved in the axial direction, and the door section 7 can be easily removed from the rear cover 3.

[0059] In particular, with the hinge structure of this embodiment, the groove portion 88 of the door body 81 can be formed on the outside of the door body 81, so not only can the shafts 80A, 80B be attached and detached in a large space, but the shafts 80A, 80B can also be attached and detached after the door body 81 is in a stably closed state, making the work easier.

[0060] In addition, the groove insertion portion 91 of the outer cover 82 has a shoulder portion 94 (shaft covering portion) located radially outside the shafts 80A, 80B inside the groove portion 88 of the door body 81, so that the shafts 80A, 80B are not exposed to the outside and are highly aesthetically pleasing.

[0061] Furthermore, the outer cover 82 has mounting protrusions 92 protruding from the main body covering portion 90, and the door main body 81 has mounting holes 84 that receive the mounting protrusions 92 of the outer cover 82. Therefore, by inserting the mounting protrusions 92 of the outer cover 82 into the mounting holes 84 of the door main body 81, the outer cover 82 can be firmly attached to the door main body 81.

[0062] Furthermore, since the groove portion 88 of the door body 81 is located between the rotating side bearing portions 85A, 86A and the rotating side bearing portions 85B, 86B, it is possible to restrict the axial movement of the shafts 80A, 80B on both sides with a single groove insertion portion 91.

[0063] Fig. 20 is an exploded perspective view of the door portion 7. As shown in Fig. 20 , a battery housing component (battery) 100 and display electronic components 110 are housed as electronic components in the space defined between the door main body 81 and the inner cover 83 of the door portion 7. A flexible printed circuit board 102 extends from the battery in the battery housing component 100 via battery contact components, and a flexible printed circuit board 112 extends from the display electronic components 110. As shown in Fig. 12 , these flexible printed circuit boards 102, 112 extend from between the door main body 81 and the inner cover 83, passing near the shaft holding portions 86A, 86B of the door main body 81, toward the frame 20, and are connected to a control board 122 (see Figs. 3 and 4) via electric wires 120 (see Figs. 3) arranged around the frame 20.

[0064] The inner cover 83 is a rectangular plate-shaped member and has an edge 141 (first edge) that is distant from the shafts 80A and 80B, an edge 142 (second edge) that is closer to the shafts 80A and 80B than the edge 141, and edges 143 and 144 that connect the edge 141 and the edge 142. The inner cover 83 also has a film pressing portion 150 that presses the photographic film stored in the film storage space S forward. The film pressing portion 150 is biased forward by a spring (not shown).

[0065] Six screw holes 152 are formed in the inner cover 83, and screws 130 serving as fasteners are inserted into these screw holes 152. The door main body 81 has six screw fastening portions 134 corresponding to the screw holes 152 of the inner cover 83, and the inner cover 83 is fixed to the door main body 81 by fastening the screws 130 inserted into the screw holes 152 of the inner cover 83 to the screw fastening portions 134 of the door main body 81. In this embodiment, the screws 130 are arranged in a total of six locations: near the four corners of the battery housing component 100 and on both sides of the display electronic component 110 in the X direction.

[0066] The inner cover 83 has a plurality of protruding pieces 145 protruding in the +Y direction from the edge portion 141 and an elastically deformable hook portion 146 provided on the edge portion 142. Although the inner cover 83 in this embodiment has two protruding pieces 145, the number of protruding pieces 145 is not limited to this. The door body 81 is provided with cover engagement holes 131 (first cover engagement portions) with which the protruding pieces 145 of the inner cover 83 engage. In this embodiment, two cover engagement holes 131 are provided corresponding to the two protruding pieces 145, but it is also possible to configure one cover engagement hole 131 so that multiple protruding pieces 145 engage with each other.

[0067] 15 , the door main body 81 is provided with a cover engaging portion 132 (second cover engaging portion) that can engage with the hook portion 146 of the inner cover 83. As shown in FIG. 21 , while the protruding piece 145 of the inner cover 83 is engaged with the cover engaging hole 131 of the door main body 81, the inner cover 83 can be rotated around the protruding piece 145 to engage the hook portion 146 with the cover engaging portion 132 of the door main body 81. In this way, the flexible printed circuit boards 102, 112 are sandwiched and fixed between the door main body 81 and the inner cover 83.

[0068] As shown in Figure 20, in this embodiment, the two flexible printed circuit boards 102, 112 extend through both sides of the hook portion 146 of the inner cover 83, so that both flexible printed circuit boards 102, 112 can be firmly sandwiched and fixed between the door body 81 and the inner cover 83.

[0069] When attaching the inner cover 83 to the door body 81, first, the protruding piece 145 of the inner cover 83 is engaged with the cover engaging hole 131 of the door body 81, and then, as shown in FIG. 21 , the inner cover 83 is rotated around the protruding piece 145 to engage the hook portion 146 with the cover engaging portion 132 of the door body 81. This temporarily fastens the door body 81 and the inner cover 83 with the flexible printed circuit boards 102, 112 sandwiched between them. After the temporary fastening, the screws 130 are inserted into the screw holes 152 of the inner cover 83 and fastened to the screw fastening portions 134 of the door body 81, thereby firmly fixing the inner cover 83 to the door body 81.

[0070] Furthermore, as shown in FIG. 14, the cover engagement portion 132 of the door body 81 and the hook portion 146 of the inner cover 83 that engages therewith are exposed on the outer surface 81A of the door body 81, but as described above, the outer surface 81A of the door body 81 is covered with the outer cover 82, and therefore the cover engagement portion 132 and the hook portion 146 can be hidden by the outer cover 82, and the aesthetic quality of the camera device 1 can be maintained at a high level.

[0071] As described above, the camera device 1 in this embodiment includes a frame 20 having a film storage space S therein for storing photographic film, a rear cover 3 (casing) that covers at least a portion of the frame 20, and a door section 7 that is attached to the rear cover 3 so as to be rotatable about shafts 80A and 80B (rotation axes). The door section 7 includes a door main body 81, an inner cover 83 that is attached to the frame 20 side of the door main body 81, electronic components 100 and 110 that are housed in a space defined between the door main body 81 and the inner cover 83, flexible printed circuit boards 102 and 112 that extend from the electronic components 100 and 110 toward the frame 20, passing between the door main body 81 and the inner cover 83 near the shafts 80A and 80B, and screws 130 (fixtures) that fix the inner cover 83 to the door main body 81. The inner cover 83 has an edge 141 (first edge) away from the shafts 80A, 80B, an edge 142 (second edge) closer to the shafts 80A, 80B than the edge 141, a plurality of protruding pieces 145 protruding from the edge 141, and a hook portion 146 provided on the edge 142. The door body 81 has a cover engagement hole 131 (first cover engagement portion) with which the protruding pieces 145 of the inner cover 83 engage, and a cover engagement portion 132 (second cover engagement portion) with which the hook portion 146 of the inner cover 83 engages. With this configuration, when attaching the inner cover 83 to the door body 81, the protruding pieces 145 and the hook portions 146 of the inner cover 83 are engaged with the cover engaging holes 131 and the cover engaging portions 132 of the door body 81, respectively, thereby temporarily fastening the door body 81 and the inner cover 83 with the flexible printed circuit boards 102, 112 sandwiched between the door body 81 and the inner cover 83. This temporary fastening allows the inner cover 83 to be fixed to the door body 81 without being affected by the repulsive force from the flexible printed circuit boards 102, 112, making it easy to fix the inner cover 83 to the door body 81.

[0072] Furthermore, since the flexible printed circuit boards 102, 112 extend through both sides of the hook portion 146 of the inner cover 83, the two flexible printed circuit boards 102, 112 can be firmly sandwiched and fixed between the door body 81 and the inner cover 83.

[0073] Furthermore, the screws 130 as fixing devices are arranged near the four corners of the battery accommodating component 100 as an electronic component, and therefore the battery accommodating component 100 can be firmly fixed to the door body 81 by the screws 130, so that the battery accommodating component 100 can be maintained in a strong state against the attachment and detachment of the battery by user operation.

[0074] In addition, the door section 7 has an outer cover 82 that covers the portion of the outer surface of the door body 81 where the cover engagement portion 132 is provided, so that the cover engagement portion 132 and the hook portion 146 exposed on the outer surface 81A of the door body 81 can be hidden by the outer cover 82, thereby maintaining a high level of aesthetic appeal for the camera device 1.
