PURPOSE:To suppress the movement of an examinee while reducing the mental load to the examinee and to obtain data free from an artifact, by allowing the examinee entering a narrow examinee introducing space to look the optical image showing the data relating to the photographing time projected into the space by an optical image fiber. CONSTITUTION:An examinee P enters a narrow examinee introducing space 1a. A display device 9 calculates a residual photographing time on the basis of the pulse sequence due to a computer system to display, for example, '3' showing the residual photographing time of 3min by the emission of light from a light emitting diode. The optical image of '3' displayed on the display device 9 is introduced into an optical image fiber 7 through a lens 7d and end surface 7c thereof and projected on a projection plate 8 through the end surface 7a and lens 7b present in the space 1a. Since the examinee P can look the optical image of '3' showing the residual photographing time of 3min and can successively confirm the advance state of photographing, the examinee can suppress a feeling of uneasiness and becomes possible to suppress unnecessary motion himself and good image data free from an artifact is obtained under a constant posture generating no unnecessary motion.
