The battery cover 21 is an external part formed of a synthetic resin material, and includes a mechanism that is locked by being engaged with the battery chamber forming member 6. The fixing plate 23 is fixed to the battery cover 21 with screws 24 in a state where the inner plate 22 is sandwiched between the battery cover 21 and the fixing plate 23. Two shaft holding portions 22 a into which the rotary shaft 3 is inserted are formed at one end of the inner plate 22. The shaft holding portions 22a are each formed in a curling shape that winds the inner plate 22 in the plate thickness direction. The inner side of the shaft holding portion 22a has a substantially cylindrical shape. When the rotating shaft 3 is inserted into the shaft holding portion 22a, the inner plate 22 rotates the rotating shaft 3 between the rotating shaft 3 and the shaft holding portion 22a. A gap is formed so as to rotate as a moving center.

  The fixing plate 23 and the battery cover 21 are fixed by screws 24, but the inner plate 22 is only sandwiched between the fixing plate 23 and the battery cover 21. Therefore, the fixed plate 23 and the battery cover 21 can freely slide with respect to the inner plate 22. When inserting / removing a battery to be attached to the digital camera 1, the battery cover 21 and the battery chamber forming member are slid by sliding the battery cover 21 as shown in FIG. 1 (c) from the state shown in FIG. 1 (b). 6 is released. In the state of FIG. 1C, the battery cover 2 is opened by rotating the battery cover 2 around the rotation shaft 3, and the mounting opening 6 a formed in the battery chamber forming member 6 is opened. Let open.

  FIG. 4 is a simplified diagram for explaining the attachment state of the battery lid 2. 4A is an overall view, and FIG. 4B is an enlarged view of a portion A in FIG. 4A.

  When the battery cover 2 is closed, in order to maintain the quality of the appearance, it is possible to minimize the gap between the battery cover 21 of the exterior portion and the back cover unit 12, the front cover unit 13, and the side cover 19b. is necessary.

  In the present embodiment, as shown in FIG. 4A, both ends of the rotating shaft 3 are held by two shaft fitting portions 6 b formed in the battery chamber forming member 6. As shown in FIG. 4B, a gap X is formed between one end of the rotating shaft 3 and the shaft fitting portion 6b. The gap X is designed to have an extremely small size. Thereby, the rotating shaft 3 is positioned with high accuracy with respect to the battery chamber forming member 6. Further, since the battery chamber forming member 6 is made of resin, a part of the shaft fitting portion 6 b may be made smaller than the shaft diameter of the rotating shaft 3. By comprising in this way, when inserting the rotating shaft 3 in the shaft fitting part 6b, the rotating shaft 3 is lightly press-fitted in the shaft fitting part 6b, and the clearance X can be made still smaller.

  The tripod mounting member 5 is formed with two bearing portions (regulating portions) 5a. The tripod mounting member 5 is fixed to the battery chamber forming member 6 and the chassis member so that the two bearing portions 5a formed on the tripod mounting member 5 are positioned between the two shaft fitting portions 6b. Yes. Further, the inner plate 22 is arranged so that the two shaft holding portions 22a are positioned between the two bearing portions 5a. As shown in FIG. 4A, the rotating shaft 3 is inserted into two shaft fitting portions 6b, two bearing portions 5a, and two shaft holding portions 22a. As shown in FIG. 4B, a gap Y is formed between the bearing portion 5 a and the rotating shaft 3. The gap Y is designed to be larger than the gap X. That is, there is a backlash between the bearing portion 5 a and the rotating shaft 3. Thereby, the rotating shaft 3 is positioned by the two shaft fitting portions 6b, and the rotating shaft 3 is not positioned by the bearing portion 5a. With such a structure, the inner plate 22 can rotate about the rotation shaft 3 as a rotation center.

  FIG. 5 is an explanatory diagram of the battery lid 2. FIG. 5A is a state diagram when the battery cover 2 is in an open state, and FIG. 5B is an enlarged view of a portion B in FIG. In FIG. 5B, parts unnecessary for the description are omitted.

  In the present embodiment, the coil portions of the torsion spring that urges the battery lid 2 in the opening direction are disposed on the two shaft holding portions 22 a of the inner plate 22. Therefore, when the state shown in FIG. 1B is changed to the state shown in FIG. 1C, the battery lid 2 is rotated in the opening direction by the urging force of the torsion spring, and the state shown in FIG. It becomes a state. When the battery lid 2 is in the open state, as shown in FIG. 5B, when the battery lid 2 is in the open state, the protrusion 22 b formed on the inner plate 22 is formed on the tripod attachment member 5. It comes into contact with the stopper portion 5b. This restricts rotation of the battery lid 2 in the opening direction. The opening angle of the battery cover 2 is set to 90 degrees or more.

  The protrusion 22b that comes into contact with the stopper 5b is a non-appearance portion that does not become the appearance of the digital camera 1. Therefore, even when the protrusion 22b and the stopper portion 5b come into contact with each other many times, even if an impact is applied or an excessive force is applied to cause scratches or dents, the battery lid 2 is closed. Since the protrusion 22b is covered with the battery cover 21, the appearance quality is not impaired. In addition, since both the inner plate 22 and the tripod attachment member 5 are formed of a metal material, scratches and dents are unlikely to occur.

  When force is applied in the direction in which the battery cover 2 is opened (opening direction) when the battery cover 2 is in an open state, a large force is applied to the protrusion 22b of the inner plate 22 and the rotating shaft 3 due to the lever principle. Join. Since the inner plate 22 is made of a metal material, the inner plate 22 is not easily deformed, but the shaft fitting portion 6b that holds the rotating shaft 3 is made of resin and may be damaged. In this embodiment, the rotating shaft 3 is inserted into two bearing portions 5a. Therefore, even if a force is further applied in the opening direction from the opened state of the battery lid 2, the rotating shaft 3 contacts the bearing portion 5a before the shaft fitting portion 6b of the battery chamber forming member 6 is damaged. Since the bearing portion 5b of the tripod attachment member 5 is formed of a metal material, it is possible to suppress deformation of the shaft fitting portion 6b that is the periphery of the rotating shaft 3 and the holding portion of the rotating shaft 3. Moreover, since the shaft fitting part 6b which is a positioning part of the rotating shaft 3 is arrange | positioned on the outer side of the bearing part 5a, the positioning location of the rotating shaft 3 does not move by a deformation | transformation. In the present embodiment, the bearing portion 5a is a through hole, but may be a wall or a rib as long as the movement of the rotating shaft 3 can be restricted when a force is applied to the battery lid 2.

  Next, the heat dissipation structure of the USB connector 41 and the HDMI connector 42 will be described with reference to FIG. FIG. 6 is an explanatory diagram of the heat dissipation plate.

  The heat radiating plate 7 is provided in the vicinity of the USB connector 41 and the HDMI connector 42, and is fixed to the battery chamber forming member 6 with a screw or hook structure. The heat radiating plate 7 is formed with connector contact surfaces 7a and 7b that are in contact with the USB connector 41 and the HDMI connector 42, respectively. Since the connector contact surfaces 7a and 7b have a leaf spring structure, the USB connector 41 and the HDMI connector 42 are pressed against each other. With this structure, the heat dissipation plate 7 can be reliably brought into contact with the USB connector 41 and the HDMI connector 42.

  In the vicinity of the battery lid 2 of the heat radiating plate 7, a battery lid abutting portion 7 c having a leaf spring structure with an inclined tip is formed. Further, the inner plate 22 of the battery lid 2 has a plate contact portion 22 c formed in the vicinity of the heat dissipation plate 7. When the battery lid 2 is closed, the battery lid abutting portion 7c and the plate abutting portion 22c abut.

  In this embodiment, when the battery cover 2 is changed from the closed state to the open state, the battery cover 2 is slid from the state shown in FIG. 1B to the state shown in FIG. 1C, and then the state shown in FIG. From the state of FIG. 5 to the state of FIG. When the battery cover 2 is slid from the state of FIG. 1B to the state of FIG. 1C, only the battery cover 21 and the fixed plate 23 slide and the inner plate 22 does not move. Therefore, in the process of changing the battery cover 2 from the closed state to the open state, the inner plate 22 performs only the operation of rotating around the rotation shaft 3. Since the battery lid abutting portion 7c has a leaf spring structure and the tip is inclined, the heat radiating plate 7 and the inner plate 22 abut securely in the closed state. In the present embodiment, the battery lid abutting portion 7c is configured to be elastically deformed by a leaf spring structure, but the plate abutting portion 22c may be elastically deformed.

  When the digital camera 1 is in operation, the circuit board 4 performs drive control of the digital camera 1 and image processing for photographing, so that the temperature rises and becomes high. Among them, the USB connector 41 and the HDMI connector 42 are one of the mounting components that become high temperature. In this embodiment, since the USB connector 41 and the HDMI connector 42 are in contact with the heat radiating plate 7 formed of a metal material, the heat generated by the USB connector 41 and the HDMI connector 42 is conducted to the heat radiating plate 7 and the temperature rises. It is suppressed. Further, since the heat radiating plate 7 is in contact with the inner plate 22, the heat generated by the USB connector 41 and the HDMI connector 42 is conducted to the inner plate 22. Since the inner plate 22 is in contact with the tripod attachment member 5 via the rotating shaft 3, the heat generated by the USB connector 41 and the HDMI connector 42 is conducted to the tripod attachment member 5. Since the tripod mounting member 5 has a lower temperature rise than the side connector portion, and the metal material forming the tripod mounting member 5 is exposed to the exterior portion, conducting heat to the tripod mounting member 5 is a heat dissipation. Efficiency is good. Further, when a tripod is attached to the digital camera 1, the heat conduction efficiency is further increased, and the temperatures of the USB connector 41 and the HDMI connector 42 are lowered.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment, A various deformation | transformation and change are possible within the range of the summary.
