PURPOSE:To reduce the cost and to improve the reliability by using a reed switch and a magnet, so that the photographing position of a data can be switched in cases of photographing of a horizontal position and a vertical position, and decreasing a space in the thickness direction of a back cover. CONSTITUTION:A read switch 2 is placed in parallel to the longitudinal direction of a back cover 1 and a guide groove 3 inclined at the angle of 45 deg. is provided, a slider 4 is fitted into the groove so as to be freely slidable, and a magnet 5 is fixed to a recessed part 4a of the slider. In case of photographing of a horizontal position, the slider is at the lower end of the groove 3 and the read switch 2 is turned on by the magnetic force of the magnet 5, and a light emit ting part 6a becomes the completion of the preparation through a light emitting part switching circuit. In case of photographing of a vertical position, the back cover 1 is rotated counterclockwise by 90 deg.. The slider 4 is at the upper end of the groove 3, the read switch 2 becomes off without being influenced by the magnet 5, and a light emitting part 6b becomes the completion of the prepa ration through the light emitting part switching circuit. According to this consti tution, the read switch is operated exactly, and the photographing position can be switched.
