摘要： An impact-type printing device includes a printer for printing characters with a plurality of impression pressures including a high impression pressure sufficient for printing on all of the sheets of a set of copy sheets. The device also include a keyboard having a key for selecting one of the plurality of impression pressures when the device operates in a normal operation mode. The device further includes a switch for switching the device between the normal operation mode and a copy mode of operation. In the normal mode the printer is capable of printing in any of the plurality of impression pressures selected by the operator at the keyboard. In the copy mode the printer prints only with a high pressure, sufficient for printing on all of the sheets of the set of copy sheets. The device also erases a previously printed character when in the normal mode and overstrikes the previously printed character in the copy mode.

摘要： In a typewriter having text storage capability, the hyphen code that is stored in response to depression of a hyphen key is conditioned on printing position and on the codes adjacent to the hyphen code in a text string. If a hyphen is keyed after the start of the return zone, is preceded by a graphic representative code and is followed by a keyed carrier return, a distinctive hyphen code representative of a syllable hyphen is recorded. Otherwise, a regular hyphen is recorded unless the hyphen key has been depressed in conjunction with a condition key (e.g. the CODE key), in which case a code representative of a required non-breaking hyphen is recorded. As a result of so controlling the recorded hyphen codes at the time of keyboarding, the operator's intentions for hyphenation may be achieved with little departure from normal keyboarding routine.

摘要： Line end adjustment decisions for a typewriter printing from test storage are based on a set of zones that are defined along the line respective of appearance considerations for the right margin. The potential end location for each successive word ready for addition to a line is calculated and such end location is compared to the previous word's end location, by reference to the appearance zones, for determining whether or not the word should be assigned to the next line (i.e., whether or not a carrier return is inserted). By so identifying the word end positions that bracket a word with respective corresponding zones, decision logic, based on preferred responses to the various zone combinations presentable by such end points, is enabled, effectively, to impose an overall pattern of preferred line ending decisions to establish a right margin.For a preferred implementation, the line ending decisions for one or more of the zone combinations are further influenced by the position of the end point of the previous line, which consideration is important to the visual impression produced by the succeeding line ending point.

摘要： An electric typewriter includes a RAM memory for storing selected characters to be printed and for storing data relating to the present escapement position and future escapement destination of a printing head of the typewriter. A control unit operates a printer to print the stored characters in the memory unit and, when a power interrupt occurs and power is subsequently restored, the control unit accesses particular position data in the memory in accordance with the angular position of a print shaft of the typewriter at the time of the power interrupt. The accessed data is employed to define a proper return escapement position for the printing head of the typewriter.

摘要： A type wheel comprises a rotary hub, a plurality of resilient, circumferentially spaced arms extending radially outwardly from the hub and a plurality of type elements provided at the end portions of the respective arms. The type wheel is rotated until the selected type element reaches a printing position relative to a platen. One or more sheets of paper interspersed with carbon sheets are wound around the platen for printing. A lever is positioned to adjust the distance between the type wheel and the platen in accordance with the number of sheets. A printing hammer is electromagnetically actuated to resiliently move the selected arm so that the respective type element impacts against the paper through an inked ribbon to print the desired character. The length of time required for the hammer to clear the non-selected arms of the type wheel after impact is a function of the number of sheets of paper and thereby the position of the lever. An electrical circuit computes this length of time and inhibits rotation of the type wheel thereduring.

摘要： A printer, comprising a printing element which, when in operating position, is placed in a magnetic field, and is connected to a secondary winding of a transformer. This transformer has two additional secondary windings and two primary windings which are connected to a circuit so arranged that after a start pulse, two current pulses of opposite directions are successively supplied to the transformer of which only the second pulse effects movement of the printing element. The two primary windings are each connected to an amplifier, each of which supplies one of the current pulses. The input of the circuit and the amplifiers are coupled in such a way that the start pulse controls one of the amplifiers which in turn, through the two additional secondary windings and a blocking circuit, controls the other amplifier to produce the second pulse. This magnetizing of the iron in the transformer first in one direction and then in the other enables a greater change of flux to be realized with a relatively weak magnetizing current.

摘要： An arrangement for scanning a disc-shaped type carrier in a code controlled printing device has a stepping motor which is controllable in the forward and backward directions for setting the type carrier. The count of a ring counter contained in the stepping motor control, and which is set in accordance with the setting of the stepping motor, is compared, as a binary combination, in a comparator device with a binary combination assigned to a specific character, and in the event of parity of the two binary combinations, an output pulse is emitted. A scanning sector is arranged on the type carrier and extends over a plurality of characters including the specific character, preferably centrally located along the scanning sector. A scanning device produces a scanning pulse in response to rotation of the sector to or past the scanning device and the scanning pulse is conjunctively linked with the output pulse of the comparator for utilization in system synchronization.
