Abstract:
An image reading apparatus which is capable of performing accurate shading correction with simple arrangement while preventing a reference member from being scratched and paper powder and the like dust from being deposited on the reference member. The image reading apparatus comprises an image reading unit. In the image reading unit, a contact glass guides an original on an image reading location. The contact glass is held by a glass holding member. A line image sensor reads the image on the original conveyed on the image reading location, through the contact glass. The image reading unit further comprises a reference member whose image is readable by the image sensor, and a moving mechanism to move the image sensor so as to enable the image sensor to alternatively read the original and a reference surface of the reference member.

Abstract:
A camera comprises a lens unit and a camera body to which the lens unit is attached by a rotational operation. The camera body is provided with terminals including a specific terminal. Arrangement of the specific terminal is different from that of the other terminals. In detaching the lens unit from the camera body, the specific terminal is adapted to be disconnected earlier relative to the other terminals while the other terminals are connected. After the disconnection of the specific terminal has been detected, the other terminals are set to high impedance.
