    • A print element shifting apparatus has a cam (32) movable in an arc for locating a print element (10) in either of two operating positions. The cam is movable by a crank arm (42) also movable in an arc between two limit positions. The driving connections between the crank arm and the cam is effected through a pin-and-slot arrangement such that there is driving contact between the crank arm and the cam intermediate the two limit positions, and virtually no driving contact at the two limit positions, so that vibration of the crank arm is not transferred to the print element.
    • 打印元件移动装置具有可在圆弧中移动的凸轮(32),用于将打印元件(10)定位在两个操作位置中的任一个位置。 凸轮可以通过也可在两个极限位置之间的电弧中移动的曲柄臂(42)移动。 曲柄臂和凸轮之间的驱动连接通过销 - 槽配置实现,使得在两个极限位置之间在曲柄臂和凸轮之间存在驱动接触,并且在两个极限位置实际上没有驱动接触, 使得曲柄臂的振动不会传递到打印元件。

    • This disc printer uses a relatively massive, rigid print disc (22) having a flat face on which two sets of raised character fronts (21,22) are arranged in separate spirals. Advantage ously, the inner font set (21) contains machine readable characters which are printable with high resolution, and a second font set (22) arranged so that the characters are upright as they pass a print zone which is vertically offset from the zone in which the high resolution characters are printed. The print disc acts as the platen for printing. With this arrangement, the same print disc can be used to print characters onto a record medium (10) at two different elevations, while maintaining the medium flat. arid without the need to transport the medium vertically. A check printer also is dis- dosed which uses the print disc to print machine readable, high resolution characters onto the check (10) during linear transport of the check in one direction, and to print other indicia onto the check during linear transport thereof in either the same or the opposite direction.
