ABSTRACT:
A printing device for imprinting selected characters from a plurality of type wheels on a record medium is described. Control means are provided for selectively adjusting each of the type wheels to bring selected characters of each of said type wheels into registry with printing positions on the record medium. The control means includes adjusting means for each of said type wheels which are conjointly driven by a common drive means. Means are provided for inhibiting the operation of selected adjusting means when the associated type wheels have reached the selected printing position. Elastic coupling means are provided between the drive means and each adjusting means to permit the continued movement of said drive means independently of an inhibited condition of one or more of said adjusting means. Means are further provided for storing information to program the operation of the control means.
