Among the operating members 25, power switch operating members 26 and 27 execute the on/off operation of operating buttons or knobs of the power switch having varied specifications of the camera 60.
Further, among the operating members 25, a pop-up member 28 as the operating member pushes a pop-up button 66 on the camera side and moves the strobe light-emitting portion 62 to the pop-up position (in other words, light-emitting position). Furthermore, among the operating members 25, a restoring member 29 of the light-emitting portion as press means presses the rear portion 62b of the strobe light-emitting portion 62 from the rear side and returns it to the restoring position (non light-emitting position).
Referring to FIG. 6, the pop-up member 28 comprises: a press button 41; a rod 42; an edge rubber member 43; a return spring 44; and a stop ring 47.
The press button 41 is integrated with the rod 42 by inserting and shaping the rod 42. The return spring 44 which energizes the buttons in the releasing direction is inserted and then the rod 42 integral with the press button 41 is inserted from an opening 3c. Further, the rod 42 integral with the press button 41 is piercing through and attached to a through hole 3d along the Z-direction. A circular caved portion is arranged to the bottom of the opening 3c in the piercing state. A sealing O-ring 46 is inserted into the circular caved portion and is fit into the outer circumference of the rod 42 while the O-ring 46 is pressed by a press washer 45. The rod 42 is slidably supported in the shaft direction while a gap between the rod 42 and the through hole 3d is sealed (watertightened) by the O-ring 46. A stop ring 47 is attached at the contact position of the end surface of the through hole 3d of the rod 42. The releasing position of the press button 41 is determined depending on the stop ring 47 in a state in which the energizing force of the return spring 44 is applied. The edge rubber member 43 is fixed to the inner edge portion of the rod 42. The pop-up button 66 on the camera side faces the front side of the edge rubber member 43 in a state in which the camera 60 is stored. The press button 41 is pressed, thereby pressing the pop-up button 66 on the camera side.
Referring to FIGS. 6, 7, and 10, the restoring member 29 of the light-emitting portion comprises: a press button 51; a rod 52 having circular cross-sections (e.g., circular stick-shaped); a return spring 53; a stop ring 56; a screw shaft support 57; a pair of screw shafts 58; a pair of metallic rollers 59; and rubber rollers 59a attached to the outer circumference of the rollers 59.
The press button 51 is integrated with the rod 52 by inserting and shaping the rod 52. The rod 52 integral with the press button 51 is inserted from an opening 3e while the return spring 53 for energizing the buttons in the releasing direction is attached, and is piercing into a through hole 3f on the rear case 3 side in an S-direction. While the rod 52 is piercing into the through hole 3f, an O-ring 55 for sealing inserted in the circular caved portion on the bottom of the opening 3e is pressed by a press washer 54 and is fit into the outer circumference of the rod 52. A stop ring 56 is attached at the contact position of the end surface of the through hole 3f on the case side of the rod 52. The releasing position of the press button 51 is determined by the stop ring 56 while it is energized by the return spring 53. The press button 51 is slidably inserted to the opening 3e. Since an operating portion 51a of the press button 51 is projected from an upper notch portion of the opening 3e, the rotation of the rod 52 is limited.
A gap between the rod 52 and the opening 3e is watertightened by the O-ring 55 and, simultaneously, the rotation of the rod 52 is slidably limited and the rod 52 is supported. The S-direction for inserting the rod 52 is inclined with a predetermined angle α a in the down direction to the front side of the Z-direction (not in parallel), the roller at the edges of the rod 52 presses the rear portion 62b of the strobe light-emitting portion 62 by pressing the rear portion 62d from the upper diagonal direction. Owing to the angle α, while the strobe light-emitting portion 62 is pressed by rollers 59, an axis direction friction force generated by the rod 52 and through hole 3f is relatively reduced.
The rollers 59 are assembled at the edge portion in the case of the rod 52 which pierces into the through hole 3f. That is, referring to FIGS. 7 and 10, the screw shaft support 57 is fit into a fitting hole 57a and is attached to the edge portion of the rod 52. The pair of rollers 59 fixedly having rubber rollers 59b is rotatably inserted to the outer diameter portion of the pair of screw shafts 58. Screw portions 58b of the pair of screw shafts 58 are screwed, from both sides of the screw shaft support 57, to a screw portion 57b of the screw shaft support 57. In the screwed state, edge portions 58a of the screw shafts 58 are engaged with pin holes 52a of the edge portion of the rod 52. Therefore, the screw shaft support 57 which supports the rollers 59 and the screw shafts 58 are fixed to the edge portion of the rod 52. The pair of rollers 59 having rubber rollers 59b is positioned on the right and left sides in the direction perpendicular to the Z-direction in front of the rod 52 at a predetermined interval, and the rear portion 62b of the strobe light-emitting portion 62 at the pop-up position is supported to be pressed.
A description is given of the pop-up operation and storing operation of the strobe light-emitting portion 62 by using the pop-up member 28 and the restoring member 29 of the light-emitting portion in the waterproof housing 1 with the above-mentioned structure according to the embodiment with reference to FIGS. 11 to 14.
The camera 60 is inserted in the waterproof housing 1, and the front case 2 and the rear case 3 are closed. Further, the camera 60 is stopped and then is stored in the waterproof housing 1 in the sealing state. In the storing state, the camera 60 is operated by using the power switch operating members 26 and 27.
In the camera operating state, the press button 41 of the pop-up member 28 is pressed, thereby pressing the pop-up button 66 of the camera 60 by the edge rubber member 43. Further, the strobe light-emitting portion 62 stands up at the pop-up position (light-emitting position) (refer to FIGS. 11 and 13) and the strobe photographing state is set.
After ending the strobe photographing operation, the strobe light-emitting portion 62 at the pop-up position presses the press button 51 of the restoring member 29 of the light-emitting portion. Then, the rubber rollers 59b attached to the pair of rollers 59 of the restoring member 29 of the light-emitting portion are moved along the S-direction, and the rear portion 62b of the strobe light emitting portion 62 is pressed from the upper diagonal direction and is rotated in the storing direction (refer to FIGS. 12 and 14). When the strobe light-emitting portion 62 reaches the restoring position, it is stopped by the stop member.
In the waterproof housing 1 according to the embodiment, it is possible to rotate and stand up the camera 60 from the restoring position to the pop-up position or to restore the strobe light-emitting portion 62 at the restoring position from the pop-up position by externally pressing the press button of the pop-up member 28 or restoring member 29 of the light emitting portion arranged at the rear portion of the waterproof housing 1.
In particular, the rods 52 for pressing the restoring member 29 of the light-emitting portion are inclined in the Z-direction, namely, in the optical axis O direction of the photographing lens so that it is inclined down at the predetermined angle toward the front side of the direction along the rear portion 62b of the strobe light-emitting portion 62 at the restoring position. Therefore, the rod sliding resistance against the through hole 3f on the case side due to reaction force applied from the rear portion 62b of the strobe light-emitting portion 62 is lower than the case in which the rod 52 are in parallel with the Z-direction, and the rear portion 62b of the strobe light emitting portion 62 can efficiently be pressed.
The pair of the rollers 59 of the restoring member 29 of the light-emitting portion is arranged on the right and left sides of the rods 52, namely, apart from each other by a predetermined distance on the side along the rotating shaft 62a of the strobe main body. Therefore, the rotation force to the rods 52 is lower as compared with the case in which the rollers 59 are arranged only on the single side. Further, the rotation friction force of the press button 51 is lower upon pressing the restoring member 29 of the light-emitting portion and thus the operation becomes smooth.
The present invention is not limited to the above embodiment and can variously be modified without departing from the essentials of the present invention.
