The connector 1 of the board 1 is connected to the connector 5 of the motherboard 4 while the side edge of the board 1 is fitted into A and the board 1 is slid from the mounting side, whereby the board 1 can be mounted on the motherboard 4. .

Here, the board 1 has board levers 9 and 9 at both ends of the side edge opposite to the side edge on which the connector 2 is provided.
'Is provided. As shown in FIG. 2, the substrate levers 9 and 9 'are pivotally supported so as to be rotatable with respect to the substrate 1 in directions indicated by an arrow a around the rotation shafts 9D and 9D', respectively, and in a direction opposite thereto. Have been. Therefore, the board 1 is inserted into the board supporting device 10 and the connector 2 is connected to the motherboard 4.
In this state, the contact ends 9B and 9B 'of the board levers 9 and 9' are in contact with a part of the camera body 3, respectively.

In this state, when the user removes the substrate 1, the user rotates the rotating operation end portions 9 A and 9 A ′ of the substrate levers 9 and 9 ′ with his / her finger, for example, and rotates in the direction indicated by the arrow a. The contact ends 9B and 9B 'of the board levers 9 and 9' push the camera body 3 in response to the turning operation, whereby the board 1 slides in a direction away from the motherboard 4.

Thus, the substrate 1 is taken out of the substrate supporting portion 8 by the rotation of the substrate levers 9 and 9 '.

The board levers 9 and 9 'are provided with identification information of the board 1 on their rear portions 9C and 9C', the orientation of the board 1 when the board 1 is mounted on the motherboard 4, and the mounting position with respect to the motherboard 4. Are directly displayed using a technique such as engraving or printing. As a method of displaying the guide marks MK and MK ', for example, as shown in FIG.
Are sequentially arranged in the depth direction from the front operation panel 11 side of the camera body 3, the arrangement position of each board 1 is represented by a number as mounting position information, and the board lever 9 on the right side as viewed from the front operation panel 11 is Displays the alphabet "R" representing the right, and displays the alphabet "L" representing the left on the substrate lever 9 'on the left side as viewed from the front operation panel 11, so that the substrate 1 is represented by the alphabets "R" and "L". The direction of the board 1 when mounted on the motherboard 4 is indicated.

Therefore, the character "R-1" is displayed as the guide mark MK on the substrate lever 9 on the right side of the substrate 1 arranged at the first position closest to the front operation panel 11, and the first The substrate lever 9 'on the left side of the substrate 1 disposed at the position is provided with a character "L-" as a guide mark MK'.
1 "is displayed.

On the board lever 9 on the right side of the board 1 arranged at the second position from the front operation panel 11, the character "R-2" is displayed as a guide mark MK and the second mark is displayed. Is provided as a guide mark MK 'on a substrate lever 9' on the left side of the substrate 1 arranged at the position "L-".
2 "is displayed.
