Further, a cable gripping portion 201 (see FIG. 2(b)) capable of gripping cables such as the connection cable 411 is provided detachably to the handle unit 200 at the front of the handle unit 200.
[0019] Next, the manner in which the handle unit 200 is attached and fixed to the imaging device main body 101 will be described with reference to FIG.
[0020] Fig. 2 is an external view showing a state in which the handle unit 200 has been removed from the imaging device body 101 of Fig. 1. Fig. 2(a) is a perspective view of the imaging device body 101 with the handle unit 200 removed, viewed from the left side of the imaging device body 101. Fig. 2(b) is a perspective view of the imaging device 101 with the handle unit 200 removed, viewed from the right side.
[0021] 2(a), a first fixing portion 121, a second fixing portion 122, and a third fixing portion 123 to which the handle unit 200 is fixed are provided on the top surface of the imaging device main body 101. Meanwhile, a first screw portion 221 fastened to the first fixing portion 121, a second screw portion 222 fastened to the second fixing portion 122, and a third screw portion 223 fastened to the third fixing portion 123 are provided on the bottom surface of the handle unit 200, as shown in FIG.
[0022] 2(a), a main body accessory shoe 124 to which an accessory can be attached is provided on the top surface of the imaging device main body 101. The main body accessory shoe 124 has electrical contacts. An accessory that electrically communicates with the imaging device main body 101 to expand its functionality, such as an external microphone, can be attached to the main body accessory shoe 124. Meanwhile, a handle contact portion 224 to be attached to the main body accessory shoe 124 is provided on the bottom surface of the handle unit 200, as shown in FIG. 2(b).
[0023] When attaching the handle unit 200 to the imaging device body 101, the handle unit 200 is slid forward from the rear of the top surface of the imaging device body 101, and the first screw portion 221, the second screw portion 222, and the third screw portion 223 are screwed into the first fixing portion 121, the second fixing portion 122, and the third fixing portion 123, respectively, thereby fixing the handle unit 200 to the imaging device body 101. At this time, the body accessory shoe 124 of the imaging device body 101 and the handle contact portion 224 of the handle unit 200 are electrically connected.
[0024] Here, in the imaging device body 101, the first fixing portion 121 and the body accessory shoe 124 are arranged approximately on the center of the optical axis when viewed from above the imaging device 100. Furthermore, the first fixing portion 121 is arranged on the front side of the top surface of the imaging device body 101 (the side closer to the front of the imaging device body 101), and the body accessory shoe 124 is arranged on the rear side of the imaging device body 101 (the side closer to the rear surface of the imaging device body 101). In contrast, in the handle unit 200, the first screw portion 221 and the handle contact portion 224 are arranged approximately on the center of the optical axis when viewed from below the imaging device 100. Furthermore, the first screw portion 221 is arranged on the front side of the bottom surface of the handle unit 200, and the handle contact portion 224 is arranged on the rear side of the bottom surface of the handle unit 200.
[0025] A handle accessory shoe 225 is provided on the top surface of the handle unit 200. The handle accessory shoe 225 has the same shape as the main body accessory shoe 124, and has electrical contacts like the main body accessory shoe 124. Therefore, accessories that can be attached to the main body accessory shoe 124 of the imaging device main body 101, such as the external microphone described above, can be attached to the handle accessory shoe 225.
[0026] Next, the electrical connection structure inside the handle unit 200 will be described. Fig. 3 is a diagram showing the internal configuration of the handle unit 200 of Fig. 1. Note that Fig. 3 shows a state in which the exterior cover has been removed. Fig. 3(a) is a perspective view of the handle unit 200 when viewed from its bottom surface side. Fig. 3(b) is a perspective view of the handle unit 200 when viewed from its top surface side.
[0027] 3(a), in the handle unit 200, the handle contact portion 224 is electrically connected to a first circuit board 227 by a first electrical connection part 226. In this embodiment, the first electrical connection part 226 is, for example, a flexible printed circuit board, and is routed through a narrow space in the thickness direction inside the handle unit 200.
[0028] Furthermore, in the handle unit 200, the first circuit board 227 is electrically connected to the second circuit board 229 by a second electrical connection part 228, as shown in FIG. 3(b). The second electrical connection part 228 is, for example, an internal wiring wire that is routed from the bottom to the top of the handle unit 200 through a gap in the handle frame 230 inside the handle unit 200. The second circuit board 229 is electrically connected to the handle accessory shoe 225 by a third electrical connection part 231. The third electrical connection part 231 is, for example, a flexible printed circuit board that is routed through a narrow space in the thickness direction inside the handle unit 200. With the above configuration, the handle contact part 224 of the handle unit 200 and the handle accessory shoe 225 are electrically connected so as to be able to communicate electrically by the internal circuit boards and electrical connection parts.
[0029] Furthermore, the first circuit board 227 is arranged near the handle contact portion 224, and the second circuit board 229 is arranged near the handle accessory shoe 225. As will be described later, the handle unit 200 is configured to transmit signals for electrical communication from the main body accessory shoe 124. For this reason, the first circuit board 227, which is arranged near the handle contact portion 224 that connects to the imaging device main body 101, and the second circuit board 229, which is arranged near the handle accessory shoe 225 that connects to an accessory, are each equipped with a correction circuit including a buffer that corrects signals for electrical communication.
[0030] FIG. 4 is an external view showing an external microphone 350 attached to the imaging device body 101 of FIG. 1. For example, as shown in FIG. 4, the external microphone 350, which is an external accessory, is attached to the body accessory shoe 124 at the rear of the top surface of the imaging device body 101. The external microphone 350 becomes usable when electrically connected to the imaging device body 101 through electrical wiring components (not shown). The external microphone 350 has functions such as directivity switching and digital signal processing, and is capable of recording audio of higher quality than the built-in microphone unit 103 of the imaging device body 101. In other words, attaching the external microphone 350 to the imaging device body 101 can expand the audio functionality of the imaging device body 101. Furthermore, by locating the body accessory shoe 124 at the rear of the imaging device body 101 as described above, the external microphone 350 can be easily attached from the rear of the imaging device body 101.
[0031] 5 is an external view showing an external microphone 350 attached to the handle unit 200 fixed to the imaging device body 101 of FIG. 1. As described with reference to FIGS. 2 and 3, when the handle unit 200 is attached to the imaging device body 101, the body accessory shoe 124 of the imaging device body 101 and the handle contact portion 224 of the handle unit 200 are electrically connected. In this state, the first screw portion 221, the second screw portion 222, and the third screw portion 223 are tightened, respectively, to fix the handle unit 200 to the imaging device body 101. An external accessory, an external microphone 350, is attached to the handle accessory shoe 225 on the front top surface of the handle unit 200. In this state, the external microphone 350 is connected to the handle contact portion 224 from the handle accessory shoe 225 via electrical connection components inside the handle unit 200, and is further connected to the body accessory shoe 124 of the imaging device body 101 so as to be able to communicate electrically. This allows the external microphone 350 to electrically communicate with the imaging device body 101 and become usable. In other words, accessories that can be attached to and used on the imaging device body 101 can also be attached and used when the handle unit 200 is attached to the imaging device body 101. In other words, signals for electrical communication are transmitted through electrical connection components provided in the handle unit 200, allowing accessories to be attached and used in different positions. Therefore, accessories can be used in accordance with various usage patterns of the imaging device 100 without providing a new accessory shoe on the imaging device body 101. This improves convenience during shooting without increasing the size of the imaging device body 101. For example, when it is desired to attach the external microphone 350 higher than the imaging device body 101 or closer to the subject, the external microphone 350 can be attached when the handle unit 200 is attached to the imaging device body 101.
[0032] Furthermore, as described above, the handle accessory shoe 225 is disposed in front of the handle unit 200, so that the photographer can hold the handle unit 200 without any obstruction even when an accessory is attached.
[0033] In the present embodiment, a configuration has been described in which the imaging device body 101 and the handle unit 200 each have one accessory shoe, but the present invention is not limited to this configuration. For example, the handle unit 200 may have multiple accessory shoes, and these multiple accessory shoes may have the same specifications or different specifications. Furthermore, these multiple accessory shoes may be configured to be usable simultaneously, or they may not be usable simultaneously and must be switched between for use.
[0034] Next, the configuration of the bottom surface of the handle unit 200 will be described with reference to Fig. 6. Fig. 6 is an external view of the bottom surface of the handle unit 200 of Fig. 1.
[0035] 6, a plurality of ribs, specifically a first convex shape 505, a second convex shape 506, and a third convex shape 507, are provided on the bottom surface of the handle unit 200. The first convex shape 505 is disposed in the vicinity of the first screw portion 221. In the present embodiment, the first convex shape 505 has a constant width along the optical axis direction relative to the first screw portion 221, and is a convex shape that protrudes from the bottom surface of the handle unit 200 in the −Y direction (the direction toward the imaging device body 101).
[0036] Similar to the first convex shape 505, the second convex shape 506 is also disposed near the first screw portion 221 and is disposed at a position facing the first convex shape 505 across the optical axis. The second convex shape 506 has substantially the same shape as the first convex shape 505. The first convex shape 505 and the second convex shape 506 are disposed substantially parallel to each other.
[0037] The third convex shape 507 is disposed approximately at the center of the second screw portion 222 and the third screw portion 223, and has a convex shape that protrudes in the −Y direction (direction toward the imaging device body 101) from the bottom surface of the handle unit 200. The third convex shape 507 is formed so as to surround three surfaces, namely the back surface of the handle contact portion 224 and both the left and right side surfaces of the handle contact portion 224, and has an approximately U-shaped convex shape in which a third convex left side portion 507a, a third convex rear side portion 507b, and a third convex right side portion 507c are connected.
[0038] Furthermore, the rib of the third convex shape 507 is not arranged on the front side of the handle contact portion 224. This is an opening that allows the handle unit 200 to slide from the rear side of the imaging device body 101 toward the front side for connection.
[0039] As shown in FIG. 6 , a first screw portion 221 is provided at the front of the handle unit 200, and a second screw portion 222 and a third screw portion 223 are provided at the rear of the handle unit 200. The second screw portion 222 and the third screw portion 223 are disposed at positions facing each other across the optical axis when viewed from the bottom surface of the handle unit 200. The handle contact portion 224 is disposed approximately on the optical axis. That is, the handle contact portion 224 is disposed at an intermediate position between the second screw portion 222 and the third screw portion 223. The handle contact portion 224 is disposed at a position on the bottom surface of the handle unit 200 that overlaps with at least a portion of the area formed by connecting the first screw portion 221, the second screw portion 222, and the third screw portion 223. By arranging the handle contact portion 224 in this positional relationship, the handle contact portion 224 fits within an area that is firmly fixed by the three fixing portions, thereby improving the connection reliability of the contacts.
[0040] Next, the relationship between the three convex shapes provided on the handle unit 200 and the handle contact portion 224 will be described with reference to FIG.
[0041] Fig. 7 is a side view of the handle unit 200 of Fig. 1. As shown in Fig. 7, the third convex shape 507 protrudes downward from the handle contact portion 224 when viewed from the side of the handle unit 200.
[0042] Plane 508 indicates a plane formed by connecting the base portions of first convex shape 505, second convex shape 506, and third convex shape 507. Plane 509 indicates a plane formed by connecting the protruding portions of first convex shape 505, second convex shape 506, and third convex shape 507, that is, a plane formed by connecting the outermost contours of the bottom side of handle unit 200. As shown in FIG. 7 , by arranging all of handle contact portion 224 closer to handle unit 200 than plane 509, when handle unit 200 alone is placed on a floor, desk, or the like, or dropped to the ground, three ribs (first convex shape 505, second convex shape 506, and third convex shape 507) will hit before handle contact portion 224. This prevents damage to handle contact portion 224.
[0043] Next, the connection between each circuit board and the ground (GND) will be described with reference to FIG.
[0044] Figure 8 is a perspective view showing the internal configuration of the handle unit 200 of Figure 1. Note that Fig. 8 shows a state in which the exterior cover has been removed. Fig. 8(a) is a perspective view of the handle unit 200 as viewed from the bottom side, and Fig. 8(b) is a perspective view of the handle unit 200 as viewed from the top side.
[0045] As shown in Fig. 8(a), a handle contact part 224 and a first circuit board 227 are arranged on the bottom surface of the handle unit 200, and as shown in Fig. 8(b), a second circuit board 229 is arranged on the top surface side. On both side surfaces of the handle unit 200, metal plates 522 (conductive members) made of a metal material such as stainless steel are arranged.
[0046] The second circuit board 229 and the first circuit board 227 each have a portion where copper foil is exposed, and when each copper foil portion comes into contact with the metal plate 522, these circuit boards are electrically connected to the metal plate 522 which serves as ground.
[0047] As shown in Fig. 8(a), a handle engaging part 523 that engages with the imaging device body 101 is disposed around the first screw part 221 on the bottom surface of the handle unit 200. Also, as shown in Fig. 2(a), a body engaging part 125 that engages with the handle unit 200 is disposed around the first fixing part 121 on the top surface of the imaging device body 101. The handle engaging part 523 and the body engaging part 125 are each formed of a metal part. When the handle unit 200 is fixed to the imaging device body 101, the body engaging part 125 and the handle engaging part 523 engage with each other, thereby enabling them to be firmly fixed together.
[0048] The second circuit board 229, the first circuit board 227, and the handle engaging part 523 are each connected to a metal plate 522 that serves as the ground. When the handle unit 200 is fixed to the imaging device body 101, the body engaging part 125 and the handle engaging part 523 are connected. With this configuration, the reference potential of the signal when the imaging device body 101 and the handle unit 200 are electrically connected so as to be able to communicate with each other is stabilized, radiation noise can be reduced, and resistance to external noise can be improved.
[0049] While the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments and various modifications and variations are possible within the scope of the present invention.
