The first support member is configured such that a connecting portion between the blocks of the blocks excluding the plurality of blocks on the other end portion side can be bent to the same one of left and right with respect to the connecting direction. In addition, the connecting portion between the plurality of blocks on the other end portion side is bendable in a direction opposite to the connecting portion between the blocks except for the plurality of blocks on the other end portion. And

As described above, the first support member is substantially entirely U
When the other end is moved along the Y-axis direction in the state of being curved in the shape of a letter, there is a possibility that the substantially U-shaped curved portion may greatly protrude from the movement range of the transferred part. However, with the configuration as in claim 3, the first support member is
For example, it is possible to move the other end along the Y-axis direction while changing the shape from a substantially S-shaped state to a substantially L-shaped state. Can be prevented from greatly protruding from the moving range of the camera. Thus, the size of the transfer device can be reduced.
