Abstract:
A printing apparatus wherein, when an underline-start code is detected, the advance of a printing head for impressing a character immediately after said start code is stopped; the underline is printed at that spot where the character is previously impressed; and then the stopped advance of the printing head is released upon the detection of an underline end code.
Abstract:
A recording device which is mechanically separated from a processor is manually moved on the recording medium to record the characters or indicia upon it. The recording of the characters on the recording medium while moving the recording head is accomplished by the stream of ink droplets ejected from the nozzle and control signals transmitted from the processor. The control signals from the processor to the recording head are generated in response to the displacement signals generated by a signal generating means within the recording head is manually moved.
Abstract:
A control device for tabulation printing comprises a tabset register for defining each column of a printing sheet to be tabulation-printed; storing means adapted to store a printing position on the sheet in synchronism with the movement of a printing head and be operated in association with the tabset register; a tabset control register for storing a signal read out from the tabset register and defining a lower tabset position of any selected column of the printing data, and storing a signal representative of that position left-shifted from the stored position of the lower tabset signal to the extent equal to the number of digits or orders of the data where the highest orders or digits of the data are to be printed; a control means for controllably printing the highest digits or orders of the data on the corresponding position of the printing paper so that the lowest digits or orders of the data are printed in vertical alignment and on the side of the lowest tabset position.
Abstract:
The information recording apparatus comprises an input device for continuously printing on a recording tape encoded character information and encoded left and right margin position designating information which is used to determine the width of a space on a recording paper in which the encoded character information is to be printed; and a printing device having means for designating the left and right margin positions of a printing device on the recording paper in accordance with the left and right margin position designating information recorded on the recording tape, and a printing means for printing characters in a space on the recording paper between the designated left and right margin positions in accordance with the encoded character information printed on the recording tape.
Abstract:
An electronic clock device comprises time measuring means for counting hours to produce a carry signal at each 24 hours, sevenstep counter means stepped by the carry signal for counting seven days of the week, and seven display elements for displaying the days of the week in accordance with the content of the seven-step counter means.
Abstract:
A switching device includes a plurality of fixed contacts supported on a print board having an annular guide opening and arranged along the annular opening; a plurality of movable contacts formed integral with a magnetic plate and arranged to oppositely face the plurality of fixed contacts, respectively, with a clearance left therebetween; and an operating handle disposed, through the print board, on a side opposite to the side on which the magnetic plate is arranged. The handle is provided with a permanent magnet. When any one of the fixed contacts is selected by operating the handle, the corresponding movable contact is attracted, under the magnetic attraction of the permanent magnet, into contact with the fixed contact.
Abstract:
Upon one or both surfaces of an accelerating electrode having a center aperture is overlaid and fixed concentrically a disk member or members each having a center aperture tapered so as to converge toward the accelerating electrode. Unnecessary ink attached to the accelerating electrode may be sucked through the interface or interfaces between the disk member or members and the accelerating electrode under capillary action and ink attached to the disk members may readily flow toward the interfaces along the tapered peripheral surfaces or walls of the center apertures of the disk members. Grooves may be formed in the surfaces of the disk members in contact with the accelerating electrode so as to facilitate the collection and discharge of unnecessary ink sucked into the interfaces under capillary action. Removal of ink attached to the accelerating electrode may be much facilitated, thus assuring the stable operation of the accelerating electrode. In addition, fabrication of the accelerating electrode structure may be much facilitated and simplified yet with a higher degree of accuracy.
Abstract:
A programming system for an electronic computer using a cardreading device, said reading device having a card passageway adapted to feed punched cards by allowing descent of the card therethrough by gravitation. The information stored in each punched card is read by a photoelectric means while each punched card descends by gravity through the card passageway of the cardreading device.
Abstract:
An indicating system of 4-bit coded signal suitable to indicate each of the 16 possible combinations of the 4-bit coded signal by using a normal decimal numeral indicating device having a capacity for the numerical values 0-9 and combining a point indication therewith.
