摘要： A rotatable disk is stepped angularly to produce successive timing pulses, and card feed rollers are stepped angularly in synchronism with the disk, to shift the information card columnby-column in accordance with the timing pulses. The information is read-out when the card is stationary following each stepped advance of the card. Upon completion of reading out of the information in all of the card columns, the last timing pulse is extended or prolonged and, during prolongation of the last timing pulse, a read-out termination signal is produced by an end cam. Blocking means are provided to prevent insertion of a second card into the device unitl reading out of a first card has been completed.

摘要： A type wheel or wheels are rotatably mounted between the upper and lower arms of a yoke-shaped member which in turn is drivingly coupled to a rotary shaft for rotating about the axis thereof the type wheel or wheels, and the upper end of a hammering bracket is slidably fitted over the yoke-shaped member so that the striking force or impact is applied through the upper end to the rotary shaft thereby causing the latter to rotate toward the platen.

摘要： A mechanical printer with a plurality of typing wheels which are pivotable separately from the carrier is provided in which an outer shaft which causes the typing wheels to revolve in unison around the axis thereof and an inner shaft which causes rotations of the typing wheels on their own axes are coupled to driving shafts through universal joints to permit the separate pivoting, and at least one driving shaft is provided with an Oldham''s coupling obviating the need for strict alignment of the driving shafts.
