A movable unit of an electronic apparatus is movable between an accommodated position within an apparatus body and a use position projected therefrom. The movable unit popped up by pop-up springs are further popped up by an assist lever and a toggle spring. The toggle spring urges the assist lever in a first arc direction and urges the same in a second arc direction opposite to the first arc direction after passing an inflexion point. The assist lever is brought into contact with a first latching pin when the movable unit reaches an end point of a movement stroke After the movable unit has reached the end point of the movement stroke, the assist lever is brought into contact with the first latching pin to urge the movable unit in the same direction as urged by the pop-up spring.
