Abstract: An opening/closing mechanism for an opening/closing cover includes the opening/closing cover, a cover protrusion, a protrusion engagement lever, an elastic member, and a cover opening section having an operation section, the cover opening section being configured to rotate the opening/closing cover in the closed position to a second position. The cover protrusion includes a second engaging portion configured to be pushed by the protrusion engagement member when the opening/closing cover is in the second position such that the opening/closing cover remains in the second position and includes a third engaging portion configured to be pushed by the protrusion engagement member when the opening/closing cover is in a third position between the second position and the open position such that the opening/closing cover rotates from the third position to the open position.
