摘要： In an impact printer or the like having a plurality of print-hammer drive electromagnets which are respectively connected in series with switching transistors between the terminals of a voltage source, the switching transistors are normally gated into conduction by gating signals with a duration sufficient to energize the electromagnets for operating the associated print hammers. In a test mode which occurs prior to the operation of the printer, the gating signals are successively applied to the switching transistors and the duration of each gating signal is reduced so that the gated transistor remains conductive for a short interval which is insufficient to operate the hammer. The potential at a circuit junction between the respective transistor and the associated electromagnet is coupled through a voltage divider to an input of a coincidence gate which receives its another signal from the gate electrode of the associated transistor to generate a failure indication signal when the input logic states have a predetermined relation therebetween.

摘要： A printing device having a plurality of print hammers having striking surfaces arranged along a print line and print magnets provided adjacent to one another for driving the printing hammers. A magnetic interference preventing device comprises a memory for storing for each column the excitation lapse time information of the print magnets. A reader which, when exciting each print magnet is started, reads the excitation lapse time information of both print magnets adjacent to each print magnet out of the memory. The reader outputs a signal only when the excitation lapse times of both print magnets are in a predetermined range of time. An inhibitor is used for inhibiting the excitation of each print magnet when the excitation lapse times of both print magnets are within the predetermined range of time.

摘要： In a paper feed control system employing a pulse motor steppingly rotatable in response to driving pulses, paper feeding is controlled by a prepunched format tape wherein line pulses generated every one line feeding of the paper are in synchronism with perforations detected from the format tape. Briefly, the format tape is moved by the pulse motor, and when a first perforation is detected therefrom a predetermined number of the driving pulses is applied to the pulse motor, whereby the format tape is moved to an approximate midpoint of the perforation. A first line pulse is generated in response to the predetermined number of the driving pulses so that the line pulse is generated in approximate midpoint of the first perforation. Accordingly, the succeeding line pulses are generated in the approximate midpoints of the succeeding perforations.

摘要： An electrophotographic device has a photosensitive element, an electrifier that forms a uniform electrostatic potential on the photosensitive element, and a light source for irradiating the photosensitive element to obtain an electrostatic latent image that has a reduced potential. A bias potential is applied to the photosensitive element after the latent image is formed, but before it is developed, so that the reduced potential of the latent image can be maintained at a constant level. With constant potentials existing on the photosensitive element, a printed image of high quality is obtained.
