本文介绍了作者自行设计制成的半机械化快速换片装置,制作简单,便于仿制及推广,材料成本不高,其性能可以满足一般要求,能连续换片十张,胶片大小为11×14时,换片时间最短可达0.7秒,在造影检查前可选择不同的换片时间,也能在换片过程中改变不同的间隔时间。文内叙述了机械构造和实际应用,机械构造包括换片机床及摄影控制器两大部分,(原文附有结构大小径线等详细说明及图示,约4,000字。)换片机床:用木料制成,主要由一个储片箱、两个受片箱和一个推拉器组成,储片箱内装有弹簧底座,使照片匣保持向上弹动的状态,通过推拉器的木框(为只有两根横樑的梯形
This paper introduces the semi-mechanized quick changer designed by the author, which is easy to make, easy to imitate and popularize. The material cost is not high, and its performance can meet the general requirements. It can continuously change ten films and the film size is 11 × 14 , Change the shortest time up to 0.7 seconds, before the contrast test can choose a different change of time, but also change the process of changing the different intervals. The article describes the mechanical structure and practical application, mechanical structure, including the machine and photo control for two major parts of the machine, the original text with the structure of the diameter of the line and other detailed instructions and illustrations, about 4,000 words.) Change Machine: Made mainly by a storage box, two tablets and a push-pull box composition, storage box equipped with a spring base, so that the photo cartridge to maintain the state of the upward bounce, push the wooden frame (for only two Trapezoidal beam
