    摘要： A phototypesetter is disclosed having a stepping motor which actuates an escapement carriage coupled to an elongated carriage driving member. A projection lens carriage and a collimating lens carriage are selectively electromagnetically coupled to the elongated driving member, thereby to project images of varying character sizes through a focusing lens coupled to the escapement carriage, which sequentially projects focused character images across a photosensitive film on a line by line basis. A track select mirror is also selectively electromagnetically coupled to the elongated driving member for selectively projecting one of a plurality of tracks bearing characters of differing fonts carried by a rotatable font carrier element. A group of customized lens carriage positioning control codes and customized sizing codes, unique for each phototypesetter as a function of lens parameter variations, are stored within a size dictionary and a particular set, associated with the character size being typeset is read out of the dictionary and is employed to control the customized positioning of the lens carriages and image (film) positioning stepping motors. A novel technique is also disclosed whereby a customized group of the above-mentioned codes is rapidly and easily generated by an iterative image inspection process for each particular phototypesetter during manufacture.

    摘要： In a character imaging system, a selected one of a plurality of different characters (letters, numerals, symbols etc.) arrayed as windows in an otherwise opaque mask, is projected optically onto a selected location on a working surface. In this manner, laser light can be used to burn an impression into a workpiece, with successive characters spelling out words and sentences. Alternatively, the system can be used to project non-coherent light onto photographic film or onto a screen. The improvement in this type of system provided by the invention resides in the avoidance of a need to move the mask, or the working surface, or the final lens that projects the light beam onto such surface. And yet the improved system nevertheless enables sequential selection of different characters in the mask, as necessary to build up words and sentences on the working surface. This improvement is achieved by scanning a light beam that is projected onto an imaging element (concave mirror or lens), while synchronously scanning mirrors that receive the imaged beam in such a manner that the final beam is projected onto the workpiece at a desired location regardless of which character-defining window in the mask is traversed by the beam.

    摘要翻译： 在字符成像系统中，以不透明掩模排列为窗口的多个不同字符（字母，数字，符号等）中的所选择的一个被光学地投影到工作表面上的选定位置。 以这种方式，激光可以用于将印象烧成工件，连续的字符拼出单词和句子。 或者，该系统可用于将非相干光投射到照相胶片或屏幕上。 本发明提供的这种类型的系统的改进在于避免了将光束投射到这种表面上的掩模或工作表面或最终透镜的移动。 然而，改进的系统仍然能够在掩模中顺序地选择不同的字符，以便在工作表面上建立单词和句子。 通过扫描投射到成像元件（凹面镜或透镜）上的光束，同时扫描接收成像光束的反射镜，使得最终光束在期望位置投射到工件上而实现这一改进，而不管 其中掩模中的字符定义窗口被光束穿过。

    摘要： The use of a stepper motor of large steps, with a pulley type mechanical motion reducer system using a flexible cable for dividing a step of the motor into a divided output motion, and an alternative embodiment wherein a second stepper motor in the form of a two-step solenoid further alters the output by changing the position of the flexible cable anchor. The combination is illustrated in an environment of a lens in a photocomposer wherein a carriage carries a decollimating focusing lens and mirror as an escapement composition device shifted in accordance with the dictates of a program operating under specific algorithms.
