    • PURPOSE:To enable correct management of printing conditions in the development process of a multilayer color negative photograph using a color developing system, by using an exposed photographic film for managing development stepwise exposed in the daylight in advance. CONSTITUTION:An exposed photographic film stepwise exposed in the daylight of 4,700-5,800 deg.K color temp. is used to manage development. Two-stage exposures are carried in advance, preferably by using a tungsten light of 2,700- 3,300 deg.K color temp. on an upper stage, and the daylight of 4,700-5,800 deg.K on a lower stage, (for example, a number of steps is 15-30, and width of one step is 6mm.), and processing conditions are managed in the tungsten light part used when needed, and examination of processing characteristics of said film itself, and management of printing conditions are carried out in the daylight step exposure part B.
    • 目的:使用彩色显影系统,通过使用曝光的照相胶片预先在日光下逐步曝光的显影来进行打印条件的正确管理。 构成:暴露的摄影胶片在4,700-5,800 deg.K色温的日光下逐步暴露。 用于管理开发。 预先进行两级曝光,优选通过使用2,700-3,300摄氏度的色温的钨光。 在较低的阶段为4700-5800度的日光,(例如,步数为15-30,一步的宽度为6mm),处理条件在 需要时使用的钨光部件,以及所述胶片本身的加工特性的检查,以及在日光照射部分B中进行打印条件的管理。

    • PROBLEM TO BE SOLVED: To improve the accuracy of each of a positional deviation amount and a density deviation amount detected by a light receiving part, in a device detecting both of the positional deviation amount and the density deviation amount by the light receiving part provided in a direction where irradiation light is regularly reflected by a medium.SOLUTION: An irradiation part irradiates an intermediate transfer belt 41 with first irradiation light Ra1. A first optical system 831 includes an annular first incident surface A1 and changes the incident first irradiation light Ra1 to second irradiation light Ra2 in which a diameter d2 when reaching the intermediate transfer belt 41 is less than or equal to a diameter d1 when made incident on the first incident surface A1. A second optical system 832 includes a second incident surface A2 surrounded by the first incident surface A1 and changes the incident first irradiation light Ra1 to third irradiation light Ra3 in which a diameter d4 when reaching the intermediate transfer belt 41 is smaller than a diameter d3 when made incident on the second incident surface A2. The light receiving part receives reflected light obtained by regularly reflecting the second irradiation light Ra2 and the third irradiation light Ra3, to detect the positional deviation amount and density deviation amount of an image.
    • 要解决的问题:为了提高由光接收部检测出的位置偏差量和浓度偏差量的精度,在设置在由光接收部检测到的光接收部分的位置偏差量和浓度偏差量两者的装置中, 照射光被介质规则地反射的方向。解决方案:照射部分用中间转印带41照射第一照射光Ra1。 第一光学系统831包括环形的第一入射面A1,并且将入射的第一照射光Ra1改变为当到达中间转印带41时直径为d2的第二照射光Ra2小于或等于入射时的直径d1 第一个入射面A1。 第二光学系统832包括由第一入射面A1包围的第二入射面A2,并且将入射的第一照射光Ra1变更为当到达中间转印带41时直径d4小于直径d3的第三照射光Ra3, 在第二个入射面A2上发生事故。 光接收部接收通过规则反射第二照射光Ra2和第三照射光Ra3而获得的反射光,以检测图像的位置偏离量和浓度偏差量。
