  FIG. 3 is an exploded perspective view of the hinge unit 30. The hinge unit 30 includes two hinge rotation axes that are parallel to each other. In the present embodiment, of these two hinge rotation axes, the hinge rotation axis disposed above in FIG. 3 is defined as “rotation axis A”, and the hinge rotation axis disposed below in FIG. Rotation axis B ”is defined.

  As shown in FIG. 3, the stand plates 38 and 39 are fastened with screws on the left and right sides of the lower side of the main body 1 a, and the standing wall portions of the stand plates 38 and 39 are coaxial with the rotation axis B. Are provided with holes 38b and 39b. The main body 1a and the display unit 20 are movably connected by a base plate 31 (first plate member) via stand plates 38 and 39 that are integral with the main body 1a. The arm plate 32 (second plate member) is movably coupled to the base plate 31 so as to be superimposed on the base plate 31.

  As shown in FIG. 3, a pair of side surface covers 60 and 61 are fastened to the standing wall portions at both ends of the base plate 31 by two upper and lower screws 63. The side covers 60 and 61 are semi-appearance parts that are exposed to the exterior when the display unit 20 is moved with respect to the main body 1a. Therefore, the side covers 60 and 61 are painted or surface-textured. It is formed to cover up.

  The side covers 60 and 61 are formed with inclined portions 60a and 61a and concave portions 60b and 61b as cam portions, respectively. The inclined portions 60a and 61a come into contact with a follower portion (not shown) of the exterior cover 22 of the display unit 20 when the display unit 20 is stored in the main body 1a, and the surface on which the follower portion slides due to a pressing force acting at the time of storage. It becomes. Therefore, the inclined portions 60a and 61a have a mirror-finished surface with no irregularities such as embossing as sliding surfaces.

  When the display unit 20 is stored in the main body 1a, the display unit 20 is held by the main body 1a by engaging the follower portion of the outer cover 22 with the concave portions 60b and 61b.

  As shown in FIG. 3, the support pin 40 is inserted into the spacer washer 44, the hole 38b provided in the stand plate 38, the rotation shaft hole 31b1 provided in the base plate 31, and the click plate 42, and is fixed by caulking. . Similarly, the support pin 41 is inserted into the spacer washer 45, the hole 39b provided in the stand plate 39, the rotation shaft hole 31b2 provided in the base plate 31, and the click plate 43, and is fixed by caulking. As a result, the base plate 31 is connected to the stand plates 38 and 39 so as to be rotatable around the rotation axis B. When the base plate 31 receives the rotational frictional resistance force from the click plates 42 and 43, the display unit 20 is frictionally held at the rotation position of a predetermined angle.

  As shown in FIG. 3, the support pin 46 is inserted into the cover member 28, the spacer washer 51, the rotation shaft hole 32 a 1 provided in the arm plate 32, the rotation shaft hole 31 a 1 provided in the base plate 31, and the click plate 48. The caulking is fixed. Similarly, the support pin 47 is inserted into the cover member 29, the spacer washer 50, the rotation shaft hole 32a2 provided in the arm plate 32, the rotation shaft hole 31a2 provided in the base plate 31, and the click plate 49, and is fixed by caulking. . As a result, the arm plate 32 is connected to the base plate 31 so as to be rotatable about the rotation axis A. When the arm plate 32 receives the rotational frictional resistance force from the click plates 48 and 49, the display unit 20 is frictionally held at the rotational position of a predetermined angle. A flexible cover 70 is attached to the arm plate 32. The flexible cover 70 is made of a resin excellent in low-friction slidability, such as polyacetal (POM) or polyamide (PA).

  Since the cover members 28 and 29 are members that conceal part of the hinge unit 30 from the cutout portion of the exterior cover 22 so that they are not exposed to the exterior, the exterior portions of the cover members 28 and 29 are exposed to the exterior. The same surface treatment or graining as the cover 22 is performed.

  As shown in FIG. 3, a substantially U-shaped slider member 52 is fixed to both ends of the slide plate 33 (third plate member), and both end surfaces 32 b of the arm plate 32 are respectively attached to the slider member 52. Engaged to slide. That is, the slide plate 33 is slidably held with respect to the arm plate 32 via the slider member 52. The slider member 52 is made of a resin excellent in low-friction slidability, such as polyacetal (POM) or polyamide (PA). Further, both end surfaces 32b of the arm plate 32 are subjected to surface treatment for reducing friction and oil (grease) application, thereby improving slidability.

  As shown in FIG. 3, a torsion spring 34 is disposed in the concave portion 32 c formed in the arm plate 32. Each end of the torsion spring 34 is locked to locking pins 35 and 36 provided by crimping on the arm plate 32 and the slide plate 33, respectively. Thereby, the torsion spring 34 functions as a second urging member that constantly urges the slide plate 33 in the arrow S direction with respect to the arm plate 32.

  As illustrated in FIG. 3, a base plate opening 31 c and a slide plate opening 33 c are provided in a region overlapping the concave portion 32 c of the arm plate 32. Thereby, since the torsion spring 34 does not overlap the base plate 31 and the slide plate 33 in the thickness direction, the hinge unit 30 can be thinned. Even if the torsion spring 34 expands and contracts, it does not come into contact with the base plate 31 and does not come into contact with the slide plate 33.

  As shown in FIG. 3, a stopper member 37 is fixed to the slide plate 33. When the slide plate 33 is slid, the stopper member 37 comes into contact with the locking pin 35 that is caulked and fixed to the arm plate 32 when the slide plate 33 is moved by a predetermined amount. Thereby, the slide of the slide plate 33 is restricted. For the stopper member 37, for example, a resin such as polyacetal (POM) or polyamide (PA) is used, thereby reducing impact noise and ensuring good wear resistance.

  As shown in FIG. 3, a ground plate 55 for securing an electrical connection between the arm plate 32 and the slide plate 33 is attached to the concave portion 32 c of the arm plate 32. The ground plate 55 has a contact portion 55a having a spring property. The ground plate 55 is disposed so that the contact portion 55 a always contacts the slide plate 33 within the slide range of the slide plate 33. The display unit 20 illustrated in FIG. 2A is attached to the slide plate 33.

  FIG. 4A is an exploded perspective view showing the positional relationship between the hinge unit 30 and the display unit 20. FIG. 4A shows a state where the rear light shielding cover 24 is attached to the slide plate 33 for the display unit 20.

  As shown in FIG. 4A, the torsion spring 34 is exposed from the opening 24 b formed in the back light shielding cover 24. The torsion spring 34 does not overlap with the flexible plate 25 in the thickness direction. As a result, the hinge unit 30 can be made thin, and even if the torsion spring 34 expands and contracts, it does not come into contact with the flexible plate 25.

  As shown in FIG. 4A, a wire spring (spring member) 65 as an urging member is disposed on the rear light shielding cover 24. The wire spring 65 is disposed so as to be sandwiched between the flexible plates 25 and functions as a first urging member that urges the first folded portion 25d of the flexible plate 25 in the arrow T direction. FIG. 4B is a perspective view showing the structure of the wire spring 65. The wire spring 65 includes an attachment portion 65b, a first folded portion 25d flexible plate urging portion 65a, and an elastic deformation portion 65c that elastically deforms. The attachment portion 65 b is a portion where the wire spring 65 is attached to the back light shielding cover 24. The flexible plate urging portion 65a is a portion where the wire spring 65 urges the first folded portion 25d. The elastic deformation portion 65c is a portion that elastically deforms when the flexible plate urging portion 65a moves in the arrow Q direction (vertical direction) with respect to the attachment portion 65b. Since the flexible plate urging portion 65a is in direct contact with the flexible plate 25, the flexible plate urging portion 65a is coated with a resin so as not to damage the flexible plate 25. The same effect can be obtained by wrapping the protective tape around the flexible plate urging portion 65a instead of the resin coating.

  Since the urging force acts in the direction of arrow R when the attachment portion 65 b of the wire spring 65 is attached to the back light shielding cover 24, it does not come off the back light shielding cover 24. The elastic deformation portion 65c has a shape in which one or more bends (mountain folds and valley folds) are repeated, and has an axisymmetric shape on both sides. By making the elastic deformation portion 65c line-symmetrical on both sides, the flexible plate urging portion 65a can move in the arrow Q direction without tilting. The amount of movement of the flexible plate urging portion 65a can be increased by increasing the number of times the elastic deformation portion 65c is bent.

  With reference to FIG. 5 thru | or 9, the sliding operation of the display unit 20 by the hinge unit 30 and absorption of the bending of the flexible board 25 when the display unit 20 is slid are demonstrated.

  FIG. 5A is a rear perspective view of the digital camera 1 when the display unit 20 is in the storage position stored in the main body 1 a of the digital camera 1. 5B and 5C are cross-sectional views taken along the line CC in FIG. 5A, and FIG. 5B shows the upper portions of the display unit 20 and the hinge unit 30 as shown in FIG. ) Shows lower portions of the display unit 20 and the hinge unit 30, respectively. As shown in FIG. 5A, the position of the display unit 20 when the display unit 20 is housed in the main body 1a is defined as a “first position”. In this state, the follower portion of the exterior cover 22 engages with the recessed portions 60b and 61b formed on the side covers 60 and 61, respectively.

  As shown in FIGS. 5B and 5C, a protrusion-shaped portion 22a and a hollow-shaped portion 22b are formed on the upper and lower portions of the exterior cover 22 constituting the display unit 20, respectively. When the display unit 20 is rotated, each of the projection shape portion 22a and the depression shape portion 22b functions as a finger hook. In the exterior cover 22, notches 22c are provided on both sides of the protrusion-shaped portion 22a (near both upper ends of the exterior cover 22), and part of the cover members 28 and 29 are exposed from the notches 22c. ing. As described above, the same surface treatment or embossing as that of the exterior cover 22 is performed on the exposed portions of the cover members 28 and 29.

  As illustrated in FIG. 5C, the first folded portion 25 d of the flexible plate 25 is housed between the display portion 21 and the arm plate 32. The flexible plate urging portion 65 a of the wire spring 65 urges the first folded portion 25 d of the flexible plate 25 in the arrow T direction. Therefore, as illustrated in FIG. 5B, the second folded portion 25 e does not swell at the second folded portion 25 e at the top of the flexible plate 25. In the present embodiment, the flexible plate 25 can be prevented from being bent regardless of the state of the display unit 20, so that the flexible plate 25 is not violated inside the display unit 20 and disconnected.

  6A shows a digital camera when the display unit 20 is moved from the first position (storage position) in order to rotate the display unit 20 around the rotation axis A with respect to the main body 1a of the digital camera 1. FIG. 1 is a rear perspective view of FIG. 6B and 6C are cross-sectional views taken along the line DD in FIG. 6A, and FIG. 6B shows the upper portions of the display unit 20 and the hinge unit 30 as shown in FIG. ) Shows lower portions of the display unit 20 and the hinge unit 30, respectively.

  When the display unit 20 is rotated about the rotation axis A, as shown in FIG. 6A, a finger is placed on the hollow portion 22b formed on the exterior cover 22, and the lower side of the display unit 20 is photographed. Pull it out to the person. At this time, the follower portion of the exterior cover 22 and the recessed portions 60 b and 61 b formed on the side covers 60 and 61 are disengaged, and the torsion spring 34 of the hinge unit 30 acts on the display unit 20. When the engagement between the follower portion of the exterior cover 22 and the recessed portions 60b and 61b is released, the follower portion of the exterior cover 22 slides on the inclined portions 60a and 61a formed on the side covers 60 and 61, respectively. At this time, the slide plate 33 slides with respect to the arm plate 32 until the stopper member 37 fixed to the slide plate 33 comes into contact with the locking pin 35 fixed to the arm plate 32. As a result, the display unit 20 slides in the direction of arrow P. The display unit 20 can be rotated around the rotation axis A on the upper side of the digital camera 1 in the state shown in FIG.

  When the display unit 20 slides in the direction of the arrow P, the first folded portion 25d of the flexible plate 25 resists the urging force of the flexible plate urging portion 65a of the wire spring 65, as shown in FIG. It moves in the direction of arrow U, which is the opposite direction to the direction of arrow P.

  FIG. 7A is a rear perspective view showing a state in which the display unit 20 is rotated about 180 ° around the rotation axis A with respect to the main body 1a of the digital camera 1 from the state shown in FIG. . FIG. 7B is a cross-sectional view taken along the line EE in FIG. 7A and shows a structure near the rotation axis A. FIG.

  In the state illustrated in FIG. 7A, the display unit 21 of the display unit 20 faces the front side of the main body 1 a of the digital camera 1. This state is a state suitable for so-called self-portrait photography, and the position of the display unit 20 at this time is defined as a “second position”. In the middle of the rotation of the display unit 21 facing the front side of the main body 1a, the GMR element detects the position of the magnet 27 and the screen display changeover switch operates, and the image (video) displayed on the display unit 21 is operated. The top and bottom are reversed.

  As shown in FIG. 7B, in this state, the second folded portion 25e of the flexible plate 25 is developed. At this time, the deployed second folded portion 25e is guided by the flexible cover 70 (see FIG. 3) attached to the arm plate 32 so as to be positioned near the center of the rotation axis A. When the display unit 20 is rotated from the state illustrated in FIG. 7A to the state illustrated in FIG. 6A, the second folded portion 25e of the flexible plate 25 is moved from the state illustrated in FIG. 7B. The state illustrated in FIG. Also in this case, the flexible plate 25 is bent along the tip of the flexible cover 70. Therefore, the flexible plate 25 is bent at the second folded portion 25e without a force acting on the flexible plate 25 in the direction of being pulled out from the inside of the display unit 20.

  When the display unit 20 is in the second position, the flexible cover 70 plays a role of reducing the area where the flexible plate 25 is exposed to the outside. As a result, it is possible to prevent the occurrence of problems such as disconnection of the signal line due to the photographer touching the flexible plate 25 unexpectedly.

  In the present embodiment, the display unit 20 at the first position is rotated about the rotation axis A after being slid in the direction away from the rotation axis A. Therefore, even if the accessory shoe 10 or the like is arranged on the upper surface of the main body 1a of the digital camera 1, a part of the display unit 21 is not hidden by the accessory shoe 10 or the like when the digital camera 1 is viewed from the front. Can visually recognize the entire display unit 21.

  When the display unit 20 is rotated from the state illustrated in FIG. 6A to the state illustrated in FIG. 5A, the second folded portion 25e of the flexible plate 25 is moved from the state illustrated in FIG. 6B. The state illustrated in FIG. Further, the first folded portion 25d of the flexible plate 25 changes from the state illustrated in FIG. 6C to the state illustrated in FIG. Since the first folded portion 25d of the flexible plate 25 is urged in the arrow T direction by the flexible plate urging portion 65a of the wire spring 65, the first folded portion 25d of the flexible plate 25 is drawn in the arrow T direction. The bending of the flexible plate 25 is eliminated. As a result, the second folded portion 25e on the upper side of the flexible plate 25 is in a state along the tip of the flexible cover 70 as shown in FIG. 5B, and the second folded portion 25e does not swell. . In the present embodiment, the flexible plate 25 can be prevented from being bent regardless of the state of the display unit 20, so that the flexible plate 25 is not violated inside the display unit 20 and disconnected.

  In addition, the digital camera 1 can rotate the display unit 20 around the rotation axis B. FIG. 8A is a rear perspective view showing a state in which the display unit 20 is rotated about the rotation axis B in the digital camera 1. FIG. 8B is a cross-sectional view taken along the line FF in FIG.

  When a finger is put on the protrusion-shaped portion 22a provided on the upper part of the exterior cover 22 constituting the display unit 20 and the upper side of the display unit 20 is caused in the direction of arrow V, the rotation axis B provided on the lower side of the hinge unit 30. The display unit 20 can be rotated around.

  When the display unit 20 is rotated about the rotation axis B, the flexible plate 25 is merely changed in the folded state of the third folded portion 25f, and unnecessary tension is not applied to the flexible plate 25, and the flexible plate 25 may be bent. Almost no.

  Next, a display unit 20a that is a modification of the display unit 20 will be described with reference to FIG. Since the hinge unit 30 combined with the display unit 20a is the same as that described above, detailed description thereof is omitted here.

  FIG. 9A is an exploded perspective view showing the positional relationship between the hinge unit 30 and the display unit 20a. FIG. 9A shows a state in which the rear light shielding cover 24 is attached to the hinge unit 30 for the display unit 20a, and the display unit 21 is not shown.

  The rear light-shielding cover 24 has a substantially U-shape as an example of a biasing member that biases the first folded portion 25d that absorbs the bending of the flexible plate 25 generated when the display unit 20a is slid. The rubber (elastic member) 66 is disposed. FIG. 9B is a perspective view showing a schematic structure of the rubber 66. The rubber 66 includes a flexible plate urging portion 66 a and an attachment portion 66 b for incorporating the rubber 66 into the back light shielding cover 24.

  Since the flexible plate urging portion 66a contacts the first folded portion 25d of the flexible plate 25, a corner R is provided. The attachment portion 66b is positioned in a state where it is attached to the back light shielding cover 24 by press fitting, and does not easily fall off or come off. The wire spring 65 as an example of the urging member described above is configured such that the flexible plate 25 is not bent by pressing the first folded portion 25d downward. On the other hand, the rubber 66 is configured such that the flexible plate 25 is not bent inside the display unit 20a by pulling the first folded portion 25d downward (T direction). That is, the rubber 66 functions as a first urging member that urges the first folded portion 25d in the T direction.
