摘要： A mechanism for shifting lines and returning the carriage to its left-margin position in power-driven typewriters and similar machines having a drive motor, and including a manually controlled member for triggering both the line shifting and carriage return operations, two linkages resiliently connected to the member and each arranged for normally producing a respective one of the operations, and various blocking means for selectively blocking the operative connection between the member and either linkage when the operation produced by that linkage is not to occur; particularly for blocking the carriage return linkage when the carriage is already in its left-margin position. A link member resiliently connected by means of a spring to the other of the arm members of the pivotally mounted lever and operable to pivot a crank provided on the clutch to engage that clutch and return the carriage, and reciprocating elements provided to block either the connecting rod or the link when only a line shift or a carriage return, respectively, is desired.
