摘要： PURPOSE:To perform optical scanning roughly from a perpendicular direction and to obtain a distortion-free image with high accuracy, by moving a light source part and a scanning deflector in parallel along the plane of an image storage plate without inclining the shaft of the scanning deflector. CONSTITUTION:The light beam L from a light source 6 is imaged onto an image storage plate 1 by a condenser lens 9, a mask 10, a collimator lens 11, a rotary polyhedral mirror 7 and a lens 8. If a feed shaft 3 is rotated by a driving mechanism consisting of an electric motor 2, a moving base plate 5 moves, for example, downward. Therefore, the optical scanning to the plate 1, i.e., the main scanning in a Y-axis direction is accomplished by the rotation of the mirror 7 and the subscanning in the Z-axis direction of an arrow B is accomplished by the downward movement of the plate 5. Since the incidence of the beam L to the plate 1 projected on the X-Z plane is roughly perpendicular, the distortion- free image is obtainable. The diagonal incidence of the beam L to the plate 1 owing to a change in the angle of deflection with the optical scanning is corrected by the lens 8.
摘要翻译：目的：大致从垂直方向进行光学扫描，并通过沿着图像存储板的平面移动光源部分和扫描偏转器而不使扫描轴倾斜，从而高精度地获得无失真的图像导流板。构成：来自光源6的光束L通过聚光透镜9，掩模10，准直透镜11，旋转多面体镜7和透镜8成像在图像存储板1上。如果进给轴3是通过由电动机2构成的驱动机构旋转，移动基板5例如向下移动。因此，通过反射镜7的旋转来实现对板1的光扫描，即Y轴方向的主扫描，并且通过向下移动来实现箭头B的Z轴方向上的副扫描由于投射到XZ平面上的板1的光束L的入射大致垂直，所以可以获得无失真的图像。通过透镜8校正由于光学扫描的偏转角度的变化引起的光束L对板1的对角线入射。

摘要： PURPOSE:To perform optical scanning on an image storage plate from roughly a perpendicular direction and to obtain a distortion-free image with high accuracy, by moving a scanning deflector along the plane of the image storage plate without inclining the shaft thereof. CONSTITUTION:The light beam L from a light source 8 is scanned on an image storage plate 1 by a condenser lens 9, a mask 10, a collimator lens 11, mirrors 12, 5, a rotary polyhedral mirror 6 and a lens 7. As the mirror 6 rotates, the beam scans the surface of the plate 1 horizontally on the X-Y plane. If a feed screw bar 2 is rotated by a driving mechanism in this stage, a base plate 4 moves downward and the optical systems 5, 6, 7 on the plate 4 moves downward as well. The optical system from the light source 8 up to the mirror 12 is fixed but the light are parallel thereafter and therefore even if the distance between the mirrors 5 and 12 changes, the beam L is made incident to the mirror 7 irrespectively of the distance. The main scanning in the Y direction on the plate 1 is accomplished by the mirror 6, and the scanning in the Z direction is moved by rotating a shaft 2.
摘要翻译：目的：通过沿着图像存储板的平面移动扫描偏转器而不使其轴倾斜，从大致垂直方向对图像存储板进行光学扫描并且以高精度获得无失真的图像。构成：来自光源8的光束L通过聚光透镜9，掩模10，准直透镜11，反射镜12,5，旋转多面体镜6和透镜7在图像存储板1上扫描。反射镜6旋转，光束在XY平面上水平地扫描板1的表面。如果在该阶段通过驱动机构使进给螺杆2旋转，则底板4向下移动，并且板4上的光学系统5,6,7也向下移动。从光源8到反射镜12的光学系统是固定的，但是光在之后是平行的，因此即使反射镜5和12之间的距离改变，光束L被入射到反射镜7，而与距离无关。通过反射镜6实现板1上的Y方向的主扫描，并且通过旋转轴2来移动Z方向上的扫描。

Hereafter, the time series electric signal is outputted similarly, and the signal becomes larger, and the change of the signal at a sampling time is reduced with respect to time. Thus, a high-S/N and high-quality image is obtained.

摘要： PURPOSE:To eliminate the variation in the amount of exposure, by correcting the variance in an output signal due to the variation in the amount of exposure at reading with the amplification factor of an amplified means to be changed. CONSTITUTION:A charge stored on a picture storage board 1 is discharged via a resistor R1 and an amplifier A1 when the image is exposed with a shutter 12 opened and the optical scanning with optical beam irradiation from a laser light is read. In opening the shutter 12, a transistor (TR) T1 is conductive and a voltage difference V corresponding to a current at image exposure is stored in an integrating circuit 14. When the optical scanning is performed, a TR T3 is opened, an AC amplifier 15 is operated, an output of an amplifier A4 is attenuated and amplified to obtain a time series electric picture signal Sf at an output terminal O. Since a gate of the TR T4 is connected to an output amplifying inversely an output of the amplifier A2, the attenuation of the TR T4 is increased as the luminous amount of exposure is increased.

摘要： PURPOSE:To increase the assuredness of medical diagnosis, by applying the data obtained based on a detecting signal to an input of a multiplier and a signal which produced attenuation of voltage by a dark decay in terms of time to the other input respectively to obtain a compensation data. CONSTITUTION:The set signals given from detectors 801-805 are supplied to a counter 839 from an optical scan control circuit via a signal line 383 and simultaneously with the end of an image exposure. The counter 839 transmits an address signal which varies momentarily to an ROM841, and the ROM841 applies a designated data to a multiplier 835. A signal that had the attenuation of voltage in terms of time due to a dark decay is applied to the input terminal of the other side of the multiplier 835 and stored to the ROM841 in the form of a compensation data with which a signal is obtained when no dark decay exists. In such a way, it is possible to improve the quality of a projected picture and then increase the assuredness of medical diagnosis.

摘要： PURPOSE:To confirm the contents of image exposure on real-time basis and to decide on a shot range, by equipping a device which detects a latent image in time series with a means of detecting image exposure momentarily. CONSTITUTION:An image intensifier 36, lens 37, and television camera 38 are added to a conventional device. When a detection plate 7 is at a stand-by position 20. An X-ray fluoroscopic image is detected momentarily through the image intensifier 36, lens 37, and television camera 38 and monitored on a CRT, etc., on real-time basis. While a table 39 is moved, a shot range, etc., are determined and a motor 25 is driven in the opposite direction to an arrow 33 at a shooting point of X-ray fluoroscopy to transmit the motion in the opposite direction to said detecting operation. Thus, the detection plate 7 is moved to an image exposure position 19 to allow X-ray photographing. An electrostatic latent image is read as an electric signal in time series as usual.
