1. An opening/closing mechanism for an opening/closing cover comprising:
the opening/closing cover rotatable between a closed position and an open position;
a cover protrusion provided to the opening/closing cover;
a protrusion engagement member that is rotatably provided and configured to engage the cover protrusion;
an elastic member configured to apply a force to the protrusion engagement member in a first rotation direction that is one rotation direction of the protrusion engagement member such that the cover protrusion is pushed by the protrusion engagement member in response to engagement of the cover protrusion by the protrusion engagement 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 between the closed position and the open position in response to an operation performed on the operation section, wherein
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
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,
the cover protrusion includes a first engaging portion configured to be pushed by the protrusion engagement member when the opening/closing cover is in the closed position such that the opening/closing cover is suppressed from rotating from the closed position to the open position, and
the first engaging portion has a surface that is above a surface of the second engaging portion in the opening direction, the surface of the first engaging portion being perpendicular to the surface of the second engaging portion.
