摘要： There is disclosed a selection mechanism for a single element printer comprising an operating link connected with the print element for the driving rotation thereof and having a first and a second input portion, and a modifying member having the link mounted thereon for pivotal motion about the first input portion. A cam follower is provided on the modifying member for engagement by a case shift cam, which is operable independent of the print shaft, to shift between a pair of locations in either of which a first character selection means cooperates with the modifying member to position the latter in either of two distinctive positions so that the first input portion of the operating link is positionable to any of four positions. The second input portion of the link is associated with a second character selection means for positioning the link to any of a plurality of pivotal positions relative to the first input portion thereof. The selection mechanism is simply constructed by connecting all the input means to a single operating link mounted inclusively on the carrier and, therefore, the selection mechanism can be manufactured at a low cost. Maintenance and adjustment of the printer can also be greatly minimized.

摘要： Print impression control mechanism for regulating the impact velocity of a single element printing head against a platen. The printing head is normally retained to a rest position which is in a fixedly spaced relationship to the platen independent of manual adjustment of an impression control lever so as to provide best visibility of printed characters on the record medium. In a first part of each print cycle, the head is brought to an intermediate position from which it is accelerated to get sufficient velocity for printing in a subsequent second part of the print cycle. Such an intermediate position is determined depending upon manual adjustment of the control lever whereby the impression of the printed characters can be determined accordingly.
