Abstract

PROBLEM TO BE SOLVED: To provide a hinge structure which is capable of opening and closing an original cover in different direction according to its posture of an image reader with which vertical placement and horizontal placement are made possible. SOLUTION: This image reader 1 makes the original cover 20 openable and closable in two directions with respect to a device body 10 by means of first and second hinge sections 30 and 31. The respective hinge sections 30 and 31 have an engaging member 50 mounted at the original cover 20 and an oscillation engaging body 51 pivotally supported at the device body, respectively. The oscillation engaging body 51 is oscillated between a first position where the engaging body does not engage the engaging member 50 when the device body 10 is put into the horizontal placement state by its own weight and a second position where the engaging body engages the same when the device body is put into the vertical placement state. The oscillation engaging body thus functions as a hinge only during this engagement.
