Abstract: An input system for an electrical machine including a mechanism for connection between each key and a shutter therefor in the keyboard of the console of the machine. The shutter interrupts light from one or more sources to one or more photocells to provide a coded input for the machine. The shutter of each key is moved by the mechanism by a snap action to avoid the need for interlocked keys. Simultaneous inputs from two keys are avoided because the shutter is moved by the mechanism at a substantially greater rate than it is possible to actuate a key manually.

Abstract: A photoelectric keyboard in which operation is achieved by insertion of a shutter in the light path between a source and a photocell in response to operation of a key. The shutter has pedetermined light transmissivity. Operation of a second key before the first is released inserts a second shutter in the light path and reduces the received light level below a predetermined threshold at the photocell so that ambiguous code generation does not occur during key overlap. So-called ''''key locks'''' are, therefore, unnecessary and individual styles of writing, including the ''''Legato-Writing'''', are not inhibited.

Abstract translation: 一种光电键盘，其中响应于键的操作，通过在光源和光电池之间的光路中插入快门来实现操作。 快门已经确定光透射率。 在第一个释放之前的第二个键的操作在光路中插入一个第二个快门，并将接收的光电平降低到低于光电管的一个预定的阈值，这样在键重叠期间就不会发生模糊的代码生成。 因此，所谓的“钥匙锁”是不会被禁止的，包括“Legato-Writing”在内的不必要和单独的写作风格。

Abstract: A punched card reader wherein the cards are received in a horizontally arranged exchangeable carousel-type cassette which is provided, at its outer rim, with radial guide slots to be fed from above. The cards are evaluated by a contact spring set arranged below the path of rotation of the cards, which is vertically adjustable. It reads the cards successively during the periods of rest in a step-by-step reading cycle.

Abstract: A transparent polygonal disk with parallel side surfaces has an axis of rotation which is parallel to the record medium. The recognition logic is provided by glass fibers which are positioned on the side of the disk from which the light emerges. Each character element of the image contains a plurality of fibers.
