摘要： Apparatus for setting and displaying a numerical value to be encoded to an electronic device, including a molded plastic support structure, a printed circuit board membrane type switch assembly which is affixed to the support structure and which includes a plurality of rows of four switches, and a like plurality of molded plastic switch actuator shafts associated respectively with the rows of four switches. Each actuator shaft has a longitudinal axis extending parallel to the associated row of four switches, and is pivotally connected to the support structure for rotation about its axis. Each shaft includes a plurality of raised annular segments for opening and closing the four switches in the adjacent row. The segments are arranged so as to provide ten combinations of open and closed switches as the shaft is rotated, to provide a 4-bit binary code corresponding to one of ten numbers 0-9, depending on the rotary shaft position. Also, each shaft includes the ten numbers 0-9 disposed about the shaft axis on the front surface of a shaft flange such that the number adjacent an indicator on the support structure corresponds to the binary code setting. The numbers 0-9 carried by each actuator shaft are oriented such that the indicated numbers are readable as a discrete number in standard decimal format corresponding to the numerical value to be encoded.
摘要翻译： 用于设置和显示要编码到电子设备的数值的设备，包括模制塑料支撑结构，固定到支撑结构并且包括多行四个开关的印刷电路板膜型开关组件，以及 分别与四行开关的行相关联的多个模制塑料开关致动器轴。 每个致动器轴具有平行于相关联的四个开关的行延伸的纵向轴线，并且枢转地连接到支撑结构以围绕其轴线旋转。 每个轴包括多个凸起的环形段，用于打开和关闭相邻行中的四个开关。 这些段被布置成当轴旋转时提供打开和闭合开关的十个组合，以提供对应于十个数字0-9中的一个的4位二进制代码，这取决于旋转轴位置。 此外，每个轴包括围绕轴法兰的前表面上的轴线设置的十个数字0-9，使得与支撑结构上的指示器相邻的数字对应于二进制代码设置。 每个致动器轴承载的数字0-9被定向成使得所指示的数字可以被读取为与要编码的数值对应的标准十进制格式的离散数字。

摘要： A method and apparatus for generating a variable pulse width code of at lt three binary coded decimal digits at a rate sufficiently greater than the film speed of a movie camera to cause a single light source in the camera to record in a continuous sequence all the bits of the three digits on the edge of a film in the camera adjacent each frame.
