PROBLEM TO BE SOLVED: To simplify the structure of a camera with respect to switching between close-up photography and normal photography. SOLUTION: The bifocal camera structure that sets normal focus or close-up focus includes a holder that holds a lens inside; a magnet 109 located near the opening of the holder; a substrate 104 on which a sensor is mounted; a case 105 fixed to the substrate and accommodating the holder; a first spring 111 fixed to the substrate and used to press up the holder; a second spring 110 fixed to a case and used to press down the holder; a housing 112 on which the case and the substrate are mounted and which allows external selection of a normal focus or close-up focus; and a magnetic body 113 which is located inside the opening of the housing and which, when a close-up focus is selected by the housing, moves to the position of the magnet, thereby separating the lens from a sensor. When the normal focus is selected from the close-up focus by the housing, the magnetic body moves to a position different from the position of the magnet, thereby bringing the lens close to the sensor.
