Therefore, when the angle of the main surface of the second charging unit 130 with respect to the main surface of the first charging unit 120 is 90 ° or more, the second power transmission coil 131 is provided as shown in FIGS. Since the charging target can be placed on the main surface 134 of the second charging unit 130 and the charging target can be charged, the second control unit 133 performs control to permit charging of the second charging unit 130. . On the other hand, when the angle of the main surface of the second charging unit 130 with respect to the main surface of the first charging unit 120 is less than 90 °, the main surface 134 of the second charging unit 130 provided with the second power transmission coil 131. Since the monitor device 220 cannot be placed on the second charging unit 130, the second control unit 133 performs control so as to prohibit charging of the charging target by the second charging unit 130. In addition, when the angle of the main surface of the 2nd charging part 130 with respect to the main surface of the 1st charging part 120 is less than 30 degrees, for example, in addition to the charging by the 2nd charging part 130, the 1st charging part 120 It is good also as a structure which prohibits charge.

  In step S108, charging of the charging target by the first charging unit 120 and the second charging unit 130 is started. If charging by the second charging unit 130 is prohibited in step S107, charging by the second charging unit 130 is not performed, and only charging of the charging target by the first charging unit 120 is performed.

  Subsequent steps S109 to S112 are performed independently by the first charging unit 120 and the second charging unit 130, respectively. For example, as shown in FIGS. 8 and 9, the main battery 215 included in the camera main body 210 is charged by the first charging unit 120, and the monitoring battery 225 included in the monitor device 220 is charged by the second charging unit 130. When charging is performed, processing is performed as follows in steps S109 to S112.

  That is, in step S109, the first charging unit 120 determines whether the main battery 215 included in the camera main body 210 is fully charged by the first charging unit 120. If the main battery 215 is not fully charged, In step S112, the first control unit 123 displays, for example, a display (not shown) provided in the first charging unit 120 with charging information such as the remaining charging capacity and charging completion time of the main battery 215 received from the camera main body 210. ) Is displayed. When the main battery 215 is fully charged, the first charging unit 120 ends the transmission of power to the camera main body 210 in step S110, completes the charging of the main battery 215, and continues. In step S111, a notification that charging of the main battery 225 has been completed is performed. Similarly, in step S109, the second charging unit 130 determines whether or not the monitor battery 225 included in the monitor device 220 is fully charged by the second charging unit 130, and the monitor battery 225 is not fully charged. Displays the charging information on, for example, a display (not shown) provided in the first charging unit 120. In addition, when the monitor battery 225 is fully charged, the second charging unit 130 ends the transmission of power to the monitor device 220 in step S110, completes the charging of the monitor battery 225, and continues. In step S111, a notification that charging of the monitor battery 225 has been completed is performed.

  In the present embodiment, the camera body 210 and the monitor device 220 can communicate with the first charging unit 120 and the second charging unit 220, and the camera body 210 and the monitor device 220 are being charged. In other words, information such as the charging state of the camera body 210 and the monitor device 220 is transmitted from the camera body 210 and the monitor device 220 to the first charging unit 120 and the second charging unit 220 at predetermined intervals. Accordingly, the first charging unit 120 and the second charging unit 130 determine whether the main unit battery 215 and the monitor battery 225 are fully charged based on information such as the charging state received from the camera main body 210 and the monitor device 220. It is possible to determine whether or not, and display charging information such as the remaining charging capacity and charging completion time of the main battery 215 and the monitor battery 225. In addition, the communication method with the camera main body 210 and the monitor apparatus 220, the 1st charging part 120, and the 2nd charging part 220 is not specifically limited, For example, the 1st power transmission coil 121, the 2nd transmission coil 131, the 1st power receiving Information may be communicated via the coil 211 and the second power receiving coil 221, or information may be communicated by wireless communication such as infrared communication or Bluetooth communication. In addition, charging information such as the remaining charging capacity and charging completion time of the main battery 215 and the monitoring battery 225 is transmitted from the charging device 100 to the monitoring device 220, and the charging information is displayed on the display unit 229 of the monitoring device 220. It is good also as a structure to display.

  As described above, the camera charging system according to the present embodiment includes the camera 200 including the camera body 210 and the monitor device 220 that can be attached to and detached from the camera body 210, the first charging unit 120, and the first charging unit 120. It is comprised from the charging device 100 which consists of the 2nd charging part 130 to join. In the present embodiment, in the camera body 210 constituting the camera 200, the first power receiving coil 211 for receiving power from the outside forms the camera body 110 as shown in FIG. 5B. Among these, it is provided on the back surface of the camera body 210 having the largest area except for the front surface of the camera body 210 on which the imaging lens is disposed. Thereby, in this embodiment, since the area of the 1st receiving coil 211 can fully be enlarged, the winding number of the 1st receiving coil 211 is increased, and the charging efficiency of the battery 215 for main bodies by the charging device 100 is increased. Can be improved.

  On the other hand, when the first power receiving coil 211 is arranged on the front surface of the camera body 210 as in the prior art, as shown in FIG. 2, an imaging lens is provided on the front surface of the camera body 210. In some cases, the area of the power receiving coil 211 cannot be sufficiently increased, and the charging efficiency of the main battery 215 is lowered. Further, as shown in FIG. 2, a grip portion may be formed on the front surface of the camera body 210. In this case, the front surface of the camera body 210 on which the first power receiving coil 211 is disposed is connected to the first charging portion. When the camera body 210 is placed on the main surface 124 of the first charging unit 120 in a state facing the 120, the thickness of the grip unit causes the camera body 210 to move relative to the first power transmission coil 121 of the first charging unit 120. The first power receiving coil 211 may be inclined and the charging efficiency of the main battery 215 may be reduced. Further, when the first power receiving coil 211 is provided in front of the camera main body 210, the grip portion cannot be decorated with metal in order to charge the main body battery 215, and the design of the grip portion is limited. There is also a problem that it ends up. In addition, even when the first power receiving coil 211 is arranged on the side surface of the camera body 210 or the lid of the battery 215 for the main body as in the prior art, the area of the first power receiving coil 211 cannot be sufficiently increased. In some cases, the charging efficiency of the main body battery 215 is lowered.

  On the other hand, in the present embodiment, the first power receiving coil 211 is the most excluding the front surface of the camera body 210 provided with the imaging lens on which light from the subject is incident, among the surfaces forming the camera body 210. By providing it on the back surface of the camera body 210 having a large area, the area of the first power receiving coil 211 can be sufficiently increased, and the charging efficiency of the battery 215 for the body can be improved. In particular, in the present embodiment, by making the monitor device 220 detachable from the camera body 210, the area of the first power receiving coil 211 can be increased on the back surface of the camera body 210.

  In this embodiment, as shown in FIGS. 8 and 9, the camera body 210 is placed on the main surface 124 of the first charging unit 120 and the monitor device 220 is mounted on the main surface 134 of the second charging unit 130. By mounting, the camera body 210 can be charged by the first charging unit 120, and the monitor device 220 can be charged by the second charging unit 130 simultaneously by a non-contact charging method using electromagnetic induction. In the present embodiment, the image data stored in the main body memory 218 of the camera main body 210 is transmitted from the main body communication unit 217 to the monitor device 220 by wireless communication while charging the camera main body 210 and the monitor device 220. Then, by displaying an image based on the transmitted image data on the display unit 229 of the monitor device 220, the monitor device 220 is used like a digital photo frame, and is captured by the camera body 210 by the user of the camera 200. Images can be provided in a slide show. As described above, in this embodiment, the monitor device 220 removed from the camera body 210 can be effectively used during charging in order to increase the area of the first power receiving coil 211 on the back surface of the camera body 210. It has become. In the present embodiment, since the second charging unit 130 rotates with respect to the first charging unit 120, the second user with respect to the main surface of the first charging unit 120 can easily view the slide show. The angle θ of the main surface of the charging unit 130 can be changed.

When the first power receiving coil 211 of the camera main body 210 and the second power receiving coil 221 of the monitor device 220 are close to each other, it is detected whether the first power receiving coil 211 and the main body 221 are close to each other. It is good also as a structure which controls so that transmission / reception of the electric power between the batteries 215 may be prohibited. For example, when the monitor device 220 is attached to the camera body 210 and the first power receiving coil 211 of the camera body 210 and the second power receiving coil 221 of the monitor device 220 are close to each other, the members provided in the monitor device 220 By providing the camera body 210 with a switch mechanism that is mechanically pressed by the camera body 210, the main body charging control unit 224 can monitor the first power receiving coil 211 and the monitor of the camera body 210 when the switch mechanism is pressed. It can be detected that the second power receiving coil 221 of the device 220 is close. Further, by providing the main body charging control unit 224 with a relay (not shown), the main body charging control unit 224 has the first power receiving coil 211 of the camera main body 210 and the second power receiving coil 221 of the monitor device 220 close to each other. In this case, the first power receiving coil 211 and the main body battery 215 are electrically disconnected by this relay, thereby prohibiting power transfer between the first power receiving coil 211 and the main body battery 215. . Similarly, when the first power receiving coil 211 of the camera body 210 and the second power receiving coil 221 of the monitor device 220 are close to each other, the monitor charging control unit 224 causes the second power receiving coil 221 and the monitor battery 225 to be connected. It is good also as a structure which prohibits transfer of electric power.

  Further, when the first power receiving coil 211 of the camera body 210 and the second power receiving coil 221 of the monitor device 220 are close to each other, for example, when the remaining capacity of the monitor battery 225 provided in the monitor device 220 is reduced. May be configured to transmit power from the camera body 210 to the monitor device 220 and charge the monitor battery 225. Similarly, when the remaining capacity of the main body battery 215 included in the camera main body 210 decreases, power may be transmitted from the monitor device 220 to the camera main body 210 to charge the main body battery 215. In this case, power can be exchanged between the camera body 210 and the monitor device 220 via electrical contacts provided in the camera body 210 and the monitor device 220.

The power transmission coil 131 and the second power receiving coil 221 of the monitor device 220 can be aligned at an appropriate position for electromagnetic induction, and the charging efficiency of the monitor battery 225 of the monitor device 220 can be further improved. In addition, the first charging unit 120 may be formed with a concave portion that matches the shape of the camera body 210, or the second charging unit 130 may be provided with a convex portion to charge the position of the monitor device 220. It is good also as a structure fixed at the position of the 2nd charging part 130 suitable for.

  In the above-described embodiment, the configuration in which the second power transmission coil 131 is provided on the main surface 134 of the second charging unit 130 has been described as an example. However, the configuration is not limited to this configuration. As shown in FIG. 12, it is good also as a structure which provides the 2nd power transmission coil 131 in the main surface 135 on the opposite side to the main surface 134 of the 2nd charging part 130a. In this case, when the angle θ of the main surface of the second charging unit 130a with respect to the main surface of the first charging unit 120 is less than 90 °, the charging target is placed on the main surface 135 of the second charging unit 130a. Since the charging target can be charged, charging of the charging target by the first charging unit 120 is permitted by the first control unit 123, and the main surface 135 by the second charging unit 130 a is allowed by the second control unit 133. Is allowed to be charged. On the other hand, when the angle θ between the main surface with respect to the first charging unit 120 and the main surface of the second charging unit 130a is 90 ° or more, the monitor device 220 is placed on the main surface 135 of the second charging unit 130a. Therefore, charging of the charging target by the first charging unit 120 is permitted by the first control unit 123, and charging of the charging target by the second charging unit 130a on the main surface 135 is prohibited by the second control unit 133.

The subject can be charged. That is, when the angle of the main surface of the second charging unit 130 with respect to the main surface of the first charging unit 120 is less than 90 °, charging by the first charging unit 120 and charging by the second charging unit 130 Charging of the charging target on the main surface 134 is permitted, and charging of the charging target on the main surface 135 by the second charging unit 130 is prohibited. Further, when the angle θ of the main surface of the second charging unit 130 with respect to the main surface of the first charging unit 120 is 90 ° or more, charging of the charging target by the first charging unit 120 and the second charging unit 130 are performed. Charging on the main surface 134 is permitted, and charging on the main surface 135 by the second charging unit 130 is prohibited.

  Further, the charging device 100 may be configured such that the second charging unit 130 is rotatable (rotatable in the yaw direction) on a horizontal plane so that the main surfaces 134 and 135 of the second charging unit 130 are interchanged with each other. . Even in this case, as described above, charging of the charging target by the first charging unit 120 and the second charging unit 130 is performed based on the angle θ of the main surface of the second charging unit 130 with respect to the main surface of the first charging unit 120. By controlling, charging of the charging target by the first charging unit 120 and the second charging unit 130 can be appropriately performed.

  Furthermore, in the above-described embodiment, as illustrated in FIG. 3, the configuration in which the monitor device 220 is mounted on the camera body 210 so as to cover the entire back surface of the camera body 210 is illustrated, but the configuration is limited to this configuration. Instead, for example, as shown in FIG. 13, the monitor device 220a may be mounted on the camera body 210a so as to cover a part of the back surface of the camera body 210a. In this case, the rear portion of the camera body 210a that is not covered by the monitor device 220a may be configured as an operation unit as shown in FIG. Further, as shown in FIG. 13B, by providing a finder (or electronic view finder) on the back of the camera body 210a, the camera body 210a may be configured to shoot without the monitor device 220. Further, the viewfinder may be externally attached to the camera body 210a.

  In addition, in the above-described embodiment, the image data transmitted from the camera body 210 is temporarily stored in the monitor memory 228, and the monitor control unit 226 reads out the image data stored in the monitor memory 228. Thus, the configuration in which the monitor control unit 226 displays an image based on the image data transmitted from the camera main body 210 on the display unit 229 is not limited to this configuration. For example, the monitor control unit The image data 226 transmitted from the camera body 210 may be displayed on the display unit 229 as it is without being stored in the monitor memory 228.

  In the above-described embodiment, when the camera body 210 and the monitor device 220 are charged, image data captured by the camera body 210 is transmitted from the camera body 210 to the monitor device 220 by wireless communication. The configuration in which an image based on the image data transmitted from the camera body 210 is displayed on the display unit 229 of the monitor device 220 is illustrated, but the configuration is not limited to this configuration. For example, the camera is connected via the charging device 100. Image data captured by the main body 210 may be transmitted from the camera main body 210 to the monitor device 220. For example, image data captured by the camera body 210 is transmitted from the camera body 210 to the first charging unit 120 via the first power receiving coil 211 and the first power transmission coil 121, and further, the first charging unit It is good also as a structure which transmits to the monitor apparatus 220 from the 2nd charging part 130 via the 2nd power transmission coil 131 and the 2nd receiving coil 221 after transmitting to the 2nd charging part from 120.
