Abstract

This punching device is for transferring information from merchandise tags to record cards. It has free-floating punches 17 which are selectively actuated by the tag T to effect a punching operation. The punches are normally retained in an inoperative position. Spring-loaded ram devices 10 and 11 are employed to move an inserted tag T toward the top of punches 17. These are allowed to move ahead of tag T until they engage the surface of the card C to be punched.

Punching Devices

This punching device is for transferring information from merchandise tags to record cards. It has free-floating punches 17 which are selectively actuated by the tag T to effect a punching operation. The punches are normally retained in an inoperative position. Spring-loaded ram devices 10 and 11 are employed to move an inserted tag T toward the top of punches 17. These are allowed to move ahead of tag T until they engage the surface of the card C to be punched.

Tag T continues to move toward punches 17. Those which encounter the imperforate portions of tag T are pushed by tag T to effectively punch card C. However, punches 17 which register with the code holes in tag T yield to card C and are pushed through the code holes in tag T and thus are rendered ineffective to produce any punchings in a card. The information is transferred in reverse coded form.
