Title: Control system for high speed printer
IPC: B41J19/18
Filed: 1974-03-04
Abstract: 1419041 Printers EXTEL CORP 4 March 1974 [9 April 1973] 9711/74 Heading G4H An electronic control system for a high-speed column-sequential dot-matrix printer, comprises a storage register including an input stage, at least one (e.g. two) intermediate stage(s), and an output stage, each capable of holding a complete (character) code word, through which each code word is passed from stage to stage, a fast or a slow print signal being selected to control the rate of printing in accordance with the presence or absence of a code word stored in a given stage. The input stage is loaded via a receiving shift register performing serial-toparallel conversion on the input code words, with which an input clock generator is synchronized. The input clock produces 16 pulses per bit time, and particular counts are recognized to, e.g. load the input stage of the storage register, shift the storage register, and start a print clock. Particular counts of the print clock are recognized to, e.g. initiate scanning of columns of a charater generator fed from the output stage of the storage register, and control a step motor advancing the column of print wires. The print clock involves stepping down (using a chain of counters) the output of an oscillator, and one counter of the chain resets the chain at one of two counts to select a slow (normal) print speed corresponding to the input data rate or a fast print speed, the latter being used when a carriage return has been ordered or the last intermediate stage of the storage register is not empty.

In a system employing VF signalling over junctions, the incoming end of a junction terminates in a bi-directional group selector, and the arrangement is such that no separate seizing signal is required, all the impulses of the first impulse train received being repeated in- D.C. form to operate the vertical magnet. The selector described is of the 200-point type arranged for double-hunting, and may give access both to local switches and to outgoing junctions. In the former case subsequent impulse trains are repeated forward in D.C. form, while in the latter case the absence of a D.C. loop on the outgoing side effects circuit changes whereby subsequent impulse trains pass through in V.F. form.

Abstract: PURPOSE:To automatically match the darkness and brightness of the items displayed in a display section to the illuminance of the circumference, by providing a control means which detects the illuminance of the circumference by means of an optical remote control photodetector and adjusts the brightness of the displaying items of the display section. CONSTITUTION:When the circumferential illuminance is high, an optical remote control photodetector 1 outputs a voltage as a signal. In this case, a momentary change in the circumferential illuminance or a noise component (alpha) by the optical remote control signal, etc., received by the optical remote control photodetector 1 is contained in the signal. Then the output of the photodetector 1 is inputted to a low-pass filter 11 through a buffer 12. The low-pass filter 11 outputs an illuminance signal F by averaging the above-mentioned signal. Therefore, the noise component (alpha) is removed. Thereafter, a comparator 13 compares the output of the low-pass filter 11 with a reference value and outputs a dark/ bright switching signal E as 'Low'. In accordance with the dark/bright switching signal E the luminous intensity adjusting section 7 of a clock deice 5 make the displaying content of a display device 9 brighter.
