FIG. 8 is a cross-sectional view of the second attachment / detachment unit 500.

  As shown in FIGS. 5 to 8, the second attachment / detachment unit 500 includes a second fixed star 510, a screw member 520, a rotation operation dial 530, a biasing member 540, a pin plug 550, a fixing member 560, and a fixing member 570. Have. The accessory 400 has an arcuate recess 401 (see FIG. 5). The second fixed seat 510 corresponds to an example of the second fixing member of the present invention, the rotary operation dial 530 corresponds to an example of the rotational operation member of the present invention, and the pin plug 550 is the second electrical connection of the present invention. It corresponds to an example of a part.

  The second fixed washer 510 is provided with a second concavo-convex portion 511 and a screw insertion hole portion 512 that are annularly arranged along the circumferential direction. The screw insertion hole 512 is disposed at the center of the second fixed star seat 510. The second fixed star 510 is fixed to the fixing member 560 with a screw or the like. The fixing member 560 is fixed to the fixing member 570 with screws or the like. The fixing member 570 is fixed to the accessory 400 with a screw or the like.

  The screw member 520 includes a male screw portion 521, a hexagonal recess 522, and an engaging portion 523. The male screw portion 521 is disposed at one end portion of the screw member 520, and the hexagonal recess 522 is disposed at the other end portion of the screw member 520 in a state of being exposed to the outside from the fixing member 570. The engaging portion 523 is formed in a T shape and is disposed in a region sandwiched between the male screw portion 521 and the hexagonal recess 522.

  The rotation operation dial 530 includes a dial operation portion 531, an engagement hole 532, and a contact surface 533. The dial operation portion 531 is formed so that its outer shape protrudes radially outward from the outer shape of the second fixed seat 510. The engagement hole 532 has a shape corresponding to the engagement portion 523 of the screw member 520 and is disposed at the center of the dial operation portion 531. When the engaging portion 523 of the screw member 520 is engaged with the engaging hole 532, the screw member 520 can also be rotated in conjunction with the rotation operation of the dial operation portion 531. The contact surface 533 is disposed around the engagement hole 532 of the dial operation unit 531.

  Here, the rotation operation dial 530 is slidable in the axial direction (longitudinal direction) of the screw member 520 with respect to the engaging portion 523. Thereby, even if the screwing of the male screw portion 521 and the female screw portion 212 proceeds, the rotation operation dial 530 can rotate the dial operation portion 531 at the same position.

  In order to attach the accessory 400 to the camera body 100, first, the second concavo-convex portion 511 of the second fixed star seat 510 provided in the second attachment / detachment portion 500 of the accessory 400 is provided in the first attachment / detachment portion 200 of the camera body 100. Engage with the first concavo-convex portion 211 of the first fixed chrysanthemum 210. Next, the dial operation portion 531 is rotated and the male screw portion 521 and the female screw portion 212 are screwed together and tightened. Thereby, it is possible to fix the accessory 400 to the camera body 100 without rattling.

  Further, when the dial operating portion 531 is rotated in the reverse direction to loosen the male screw portion 521 and the female screw portion 212, the engagement between the first uneven portion 211 and the second uneven portion 511 is released. It is possible to change the phase of the engagement position. With the phase of the engagement position changed, the dial operation portion 531 is rotated and the male screw portion 521 and the female screw portion 212 are screwed together and tightened, whereby the accessory 400 is rotated by a predetermined angle and fixed to the camera body 100. It becomes possible to do. The dial operation unit 531 protrudes radially outward from the outer shape of the accessory 400. For this reason, even when the user is holding the accessory 400, the user can rotate the dial operation unit 531 with the thumb. That is, the user can adjust the angle of the accessory 400 with one hand.

  Incidentally, it may be difficult to remove the accessory 400 from the camera body 100 when the environmental temperature changes or the rotary operation dial 530 is damaged. On the other hand, in this embodiment, since the screw member 520 includes the hexagonal recess 522 for the wrench, using the hexagonal wrench corresponding thereto, the screwing of the male screw portion 521 and the female screw portion 212 is loosened. I can do it. That is, the user can reliably remove the accessory 400 from the camera body 100.

  The urging member 540 is formed of, for example, a compression spring, and a screw member 520 is inserted and disposed in the hollow portion. One end of the urging member 540 is in pressure contact with the contact surface 533 of the rotary operation dial 530, and the other end is in pressure contact with the annular recess 571 of the fixing member 570. Thereby, since the rotation operation dial 530 is urged in one direction, the play of the rotation operation dial 530 can be suppressed. Therefore, when shooting is performed with the camera body 100 to which the accessory 400 is attached, it is possible to prevent the rattling sound of the rotation operation dial 530 from being generated.

  The pin plug 550 is provided at one end of the plug cable 551, and the other end of the plug cable 551 is electrically connected to the interior of the accessory 400 from the vicinity of the second fixed seat 510. When the pin plug 550 is inserted into the pin jack 250 provided in the first attachment / detachment part 200 of the camera body 100 and electrically connected thereto, the electrical connection is established between the camera body 100 and the accessory 400 via the plug cable 551. Communication is possible.

  In the present embodiment, the mechanical connection location and the electrical connection location between the first attachment / detachment portion 200 of the camera body 100 and the second attachment / detachment portion 500 of the accessory 400 are arranged in the vicinity. For this reason, the length of the plug cable 551 exposed to the outside of the camera body 100 and the accessory 400 can be shortened as much as possible. Thus, regardless of the angle at which the accessory 400 is fixed with respect to the camera body 100, the plug cable 551 is short, so that the routing of the plug cable 551 is stable. For this reason, when the accessory 400 is gripped and the operation member is operated, the plug cable 551 does not interfere with the user's hand, and the user's operability can be improved.

  Next, the regulating member 300 provided between the first attaching / detaching portion 200 of the camera body 100 and the second attaching / detaching portion 500 of the accessory 400 will be described with reference to FIGS. 9 to 13.

The convex portions 303a and 303b are disposed on the radially outer side of the seat engaging portion 305 and project toward the camera main body 100, and engage with the concave portions 101a and 101b of the camera main body 100 shown in FIG. By this engagement, the restriction member 300 is restricted from moving in the removal direction of the insertion / removal direction X of the pin jack 250.

  When the pin plug 550 moves in the removal direction of the insertion / removal direction X of the pin jack 250, the restriction plug 302 abuts the pin plug 550. Even when an external force is applied to the pin plug 550 in the direction in which the accessory 400 is attached to the camera body 100 in the direction in which the accessory is removed from the pin jack 250, the pin plug 550 is controlled by Abuts against the restricting portion 302. For this reason, the pin plug 550 does not come out of the pin jack 250. That is, even if an unexpected external force is applied to the plug cable 551 such as when the plug cable 551 is caught on something, the electrical connection between the camera body 100 and the accessory is maintained.

  The arc-shaped convex portion 301 is provided so as to project from the star-tooth engaging portion 305 toward the accessory 400, and engages with the arc-shaped concave portion 401 shown in FIG. Thereby, when the accessory 400 rotates with respect to the camera body 100, the circumferential end of the arc-shaped convex portion 301 and the circumferential end of the arc-shaped concave portion 401 come into contact with each other, and the rotational angle of the accessory 400 is regulated. That is, when the accessory 400 rotates, the circumferential end of the arc-shaped convex portion 301 and the circumferential end of the arc-shaped concave portion 401 abut before the plug cable 551 extending from the accessory 400 is stretched. The load on can be suppressed.

  As described above, by using the restricting member 300, it is possible to electrically connect the camera body 100 and the accessory 400 stably and to prevent the plug cable 551 from being damaged. Therefore, the reliability of the accessory 400 can be improved. it can. Further, the user can use the camera body 100 by removing the restriction member 300. For this reason, it becomes possible to deal with accessories of various shapes, and the convenience for the user can be improved.
