The power button 5 is provided for the user to operate the power ON / OFF of the camera 1.

  On the rear surface of the camera 1, there are provided a liquid crystal panel 7 and operation buttons 8 for displaying live view images for sequentially displaying captured images, image data stored in the recording medium 6, and the like. On the bottom surface of the camera 1, a lid 11 for opening and closing the battery housing 9 and holding the battery device 10 is rotatably supported. The lid 11 can be opened to a position rotated about 120 degrees from the closed state in order to improve the workability of inserting and removing the battery device 10.

  2 and 3, a plurality of (three) power connection terminals 12 for supplying power to the camera 1 are arranged on the front end face in the insertion direction Db of the battery device 10 in the battery device 10. The power connection terminal 12 includes a plus terminal, a minus terminal, and a thermistor terminal that outputs temperature information of the battery device 10. A plurality of elastically deformable connection terminals 14 are arranged on the device-side power connection connector 13 provided in the battery housing portion 9 of the camera 1 and connected to a circuit board inside the camera 1. When the battery device 10 is inserted into the battery housing 9, the power connection connector 13 and the power connection terminal 12 come into contact with each other, and power is supplied to the electric circuit inside the camera 1.

  The recording medium 6 is a microSD (registered trademark) card or other small memory card. A plurality of data communication terminals 15 for performing data communication with the camera body are arranged on the recording medium 6. On the upper surface of the battery device 10 is formed a concave recording medium holding portion for detachably holding the recording medium 6 with the data communication terminal 15 facing the upper surface. A recording medium guide groove 16 for sliding the recording medium 6 in and out of the battery device 10 along the direction Dm perpendicular to the battery insertion / extraction direction Db to the camera 1 is formed. In addition, a recording medium lock portion 17 is provided that protrudes toward the recording medium side to prevent the recording medium 6 from falling off when the recording medium 6 is completely inserted into the battery device 10. In the present embodiment, an example is shown in which the direction Db in which the battery device 10 is inserted into and removed from the camera 1 and the direction in which the recording medium 6 is inserted into and removed from the battery device 10 are perpendicular to each other. If the two insertion / extraction directions intersect each other, the same effect can be obtained.

  A plurality of elastically deformable connection terminals 19 are arranged on the communication connection connector 18 on the camera 1 side provided in the battery housing portion 9 and connected to a circuit board inside the camera 1. When the battery device 10 that holds the recording medium 6 is inserted into the battery housing 9, the communication connector 18 and the data communication terminal 15 come into contact with each other and perform data communication with an electric circuit inside the camera 1. With the above configuration, the direction in which the recording medium 6 is inserted into and removed from the battery device 10 is perpendicular to the direction in which the battery device 10 is inserted into and removed from the camera 1. Therefore, when the battery device 10 holding the recording medium 6 is removed from the battery storage unit 9, it is possible to prevent the recording medium 6 from dropping and remaining inside the battery storage unit.

  Further, the front surface of the recording medium holding portion in the battery insertion direction Db is cut out at a position where the recording medium 6 is completely inserted so as to be lower than the surface on which the data communication terminal 15 of the recording medium 6 is provided. A region 20 is formed. For this reason, when the battery device 10 is inserted into the battery housing 9, the connection terminal 19 of the communication connection connector 18 that is easily deformed is damaged in the process in which the communication connection connector 18 is relatively close to the data communication terminal 15. Can be prevented.

  At the position where the recording medium 6 is completely inserted into the battery device 10, the recording medium 6 is held at a position lower than the outer surface of the battery device 10. For this reason, even if the battery device 10 is inserted into and removed from the battery housing portion 9 with the recording medium 6 inserted into the battery device 10, the recording medium 6 and the inner wall of the battery housing portion 9 do not come into contact with each other. Can be prevented from being damaged. Moreover, the battery apparatus 10 repeats charging / discharging, and the secular change in which the external shape expands etc. generate | occur | produces. When the outer shape of the battery device 10 expands due to secular change, the central portion of the upper and lower surfaces of the battery device 10 in FIG. Therefore, in the present embodiment, the recording medium holding portion is formed so that the recording medium 6 is located near the side surface on which the power connection terminal 12 of the battery device 10 is formed. By doing so, it is possible to reduce the influence of the aging of the battery device 10 on the contact pressure between the data communication terminal 15 and the communication connection connector 18 of the recording medium 6.

  The communication connection connector 18 is formed with a guide rib 21 extending in the battery insertion direction Db. In the battery device 10, a slit 22 is formed on the same surface as the recording medium holding portion, and when the battery device 10 is inserted into the battery storage portion 9, the guide rib 21 and the slit 22 are engaged. By forming an enlarged slope portion 23 for smoothly guiding the guide rib 21 at a portion of the slit 22 where the guide rib 21 is introduced, the feeling of catching when the guide rib 21 is engaged with the slit 22 is eliminated.

  Since the pitch in the arrangement direction Dp of the data communication terminals 15 of the recording medium 6 is smaller than the power connection terminal 12 of the battery device 10, the relative position of the communication connection connector 18 and the data communication terminals 15 in the arrangement direction Dp is conventional. Required with higher accuracy. Therefore, by engaging the slit 22 with the guide rib 21, the relative position accuracy is improved because the battery storage unit 9 and the battery device 10 are positioned in the arrangement direction Dp. Further, even when the outer shape and assembly dimensions of the members of the camera 1 and the battery device 10 are varied, it is possible to prevent a connection failure between the communication connection connector 18 and the data communication terminal 15.

  4 is a cross-sectional view taken along the line AA of FIG. 1 in a state where the lid 11 of the camera 1 is closed, and a slope portion 24 is formed at a position facing the communication connection connector 18 of the battery housing portion 9. In a state where the lid 11 of the camera 1 is closed, the battery device 10 abuts on the slope portion 24 and is displaced by the pressing force P in the battery insertion direction Db applied to the battery device 10. This pressing force P is divided into Px and Py at the contact portion 25 of the battery device 10, and the pressing force Py is a direction to increase the contact pressure with respect to the data communication terminal 15 of the communication connection connector 18. Reliability of the connection state of the connector 18 is improved.

  [Embodiment 2] Next, a battery device according to Embodiment 2 will be described with reference to FIGS. The structure of the camera 1 is the same as that of the first embodiment. 5 and 6, the same components as those in the first embodiment are denoted by the same reference numerals. In the battery device 10 of the present embodiment, a recording medium guide groove 26 for sliding and inserting the recording medium 6 into the battery device 10 is formed in the same direction as the battery insertion direction Db. In addition, a recording medium lock portion 27 that protrudes toward the recording medium side to prevent the recording medium 6 from falling off when the recording medium 6 is completely inserted into the battery device 10 is provided. The insertion / extraction force required for the recording medium 6 to get over the recording medium lock portion 27 along the guide groove 26 is set to be larger than the frictional force caused by the contact pressure of the communication connection connector 18 to the data communication terminal 15. ing. As a result, when the battery device 10 holding the recording medium 6 is removed from the battery housing 9, the recording medium 6 enters the guide groove 26 against the frictional force between the communication connection connector 18 and the data communication terminal 15. Even if it slides along, it does not get over the recording medium lock part 27. That is, the recording medium lock unit 27 holds the recording medium 6 in the recording medium holding unit even when a force in a direction opposite to the direction in which the battery device 10 is removed from the camera 1 is applied to the recording medium 6. Therefore, the recording medium 6 does not fall off from the battery device 10, and it is possible to prevent the recording medium 6 from remaining in the battery storage unit 9, thereby improving user operability.
