Abstract

1,138,169. Electrically controlled printers. ANELEX CORP. 29 June, 1966 [22 July, 1965], No. 29286/66. Heading G4H. [Also in Division H3] In a high-speed printer of the kind in which the print hammers 17 are actuated from a power supply source 41 via capacitors 39, the charge on which falls when the hammers are actuated at a high rate in printing a line, there are sensing means to detect when the potential of the supply falls below a predetermined value to prevent the printing of the next line for a predetermined period. The type rotates with roll 1, a shaft encoder generating a series of codes identifying the characters as they come into printing position. Character codes are read out of memory 35 in succession by timing means 33 and compared at 31 with each of the successive character codes from encoder 7. Upon agreement the corresponding hammer magnet 21 is actuated, the current being supplied over line 23 from the bank of capacitors 39 charged by the source 41. The more rapidly the hammers are actuated the more discharged the capacitors become. The available potential is applied to a divider comprising Zener diode 61 and resistor 63. The diode subtracts a constant voltage, and the remainder is applied via diode 71 to resistor 73, and via diode 65 to capacitor 69, shunted by resistor 67. When the charge in capacitors 39 falls, the voltage across resistor 73 falls immediately, while that across resistor 67 is held up by capacitor 69. A difference amplifier 75 receiving these two voltages sets a monostable 77 if the difference is large enough, applying a positive signal of the predetermined period to the a input of NOR gate 79, which accordingly provides no advance signal for the paper feed mechanism. Interlock circuits, connected via switch 83, prevent the next line being printed until the paper has been moved. A form control device 55 controlled, for example, by a photoelectrically sensed punched tape, governs the extent of movement of the paper, to cause the next line to be printed in the next position.
