摘要： The disclosure embodies a record-processing tool and includes mechanism for activating the tool to punch or detect a code hole in a record medium. The tool is activated by a lever selectively pivoted about one of two opposite-acting fulcrums by cyclically operable means, selection being dependent on the retraction of one of the fulcrums.
