    摘要： A portable card punching device for use by students in recording their answers to tests and in similar situations so that the resulting punched card can be processed by computers comprises a frame structure defining a card receiving channel. A plurality of pushrods are provided in a row running across and above the channel such that depression of any one rod will punch a hole in a card received in the channel in a certain position along a row of points on the card corresponding to the position of the pushrod. A mechanical indexing means is provided in the frame structure and interconnected with the pushrods such that upon depression of any one rod, the card will be moved forward an incremental distance in the channel and properly indexed to a next successive row so that only one punch will appear in any one row on the card. The entire device is mechanically operated requiring no electrical connections and is sufficiently portable as to be easily carried around by a person and used as desired.
