Abstract
An image-forming apparatus includes a main body divided into a first part and a second part, an imaging unit, and a detecting device. The first part is pivotably provided to the second part to open the apparatus. The imaging unit is detachably mounted in a predetermined station of the first part. The detecting device detects whether an image forming operation can be executed or not, and is actuated only when the first part is closed to the second part with the presence of the imaging unit in the predetermined station of the first part.
