    • PURPOSE:To obtain a compact monitor device which displays a large amount of monitor information accurately by providing a hologram recording member, plural irradiating means for reproduction, plural light emitting means, and a control means which operates the irradiating means and light emitting means selectively according to a monitor signal. CONSTITUTION:A dry plate 2 consists of a glass substrate 21, a photosensitive material 22 applied on the substrate 21, and a transparent protection cover 23, and a front stereoscopic image S1 and a rear stereoscopic image S2 of a vehicle are superposed and recorded on the photosensitive material 22 as light interference fringes. White lamps 31 and 32 for reproduction are provided in front of the dry plate 2 at a right and left position while supported by a support member and the rays of light emitted by those lamps 31 and 32 are incident on the dry plate 2 at different angles. Then when the lamp 31 for reproduction is turned on, the front stereoscopic image S1 of the vehicle is reproduced and when the lamp 32 for reproduction is turned on, on the other hand, the rear stereoscopic image S2 of the vehicle is reproduced.
