Abstract: A lid of the lid opening/closing mechanism is rotatably mounted on a slide member arranged in the casing for movement along a linear guide formed on the inner surface of the casing and is moved along with the slide member along the guide direction by the linear guide while being rotated in a direction of opening the aperture. A holding unit is provided between the lid and the casing for holding the lid at an aperture closure position. The holding unit is made up of an engagement portion in the lid or in the casing and a mating engagement portion in the casing or the lid. The slide member supporting the lid for rotation is guided by the linear guide so as to be moved between a first position in which the engagement portion and the mating engagement portion of the holding unit are engaged with each other and a second position in which the engagement between the engagement portion and the mating engagement portion are released.
