Abstract

In the usual card to paper tape translator, information which appears in a given column in a card is punched in a corresponding column in a paper tape. For some purposes it is useful to translate information this way or, when desired, to punch the information appearing in more than one card column in a single tape column. This way effects a saving in paper tape. In the translator shown, information appearing in two adjacent card columns is punched in a single paper tape column.

Card To Paper Tape Translator

In the usual card to paper tape translator, information which appears in a given column in a card is punched in a corresponding column in a paper tape. For some purposes it is useful to translate information this way or, when desired, to punch the information appearing in more than one card column in a single tape column. This way effects a saving in paper tape. In the translator shown, information appearing in two adjacent card columns is punched in a single paper tape column.

The translator includes a card reader 10 which, under the control of program card 11 (lower figure) in the program drum (not shown), reads the information in a perforated card 12 and translates representative signals through suitable conductors 13 and 14 to encoders 1 and 2. Assuming eight-hole paper tape 15 is employed, the paper tape punch 16 includes two groups of punch magnets 1...4 and 5...8. One terminal of each magnet 1...4 is connected to encoder 1 while its other terminal is connected through resistor 17 to contact M associated with switch 18. Similarly one terminal of each magnet 5...8 is connected to encoder 2 while its other terminal is connected through resistor 17 to switch 18 which has another contact N. Card reader 10 has an output conductor 19 connected between the program drum and ground through a relay 20. The armature 22 is biased by spring 23 and is arranged to move between a terminal connected to the contact M and the terminal associated with switch 18.

When switch 18 is connected to M, the punch magnets 1...8 are all connected to ground through armature 22. Thus, it is possible, in response to information sensed by the card reader 10 in a single column such as column A of card 12, to energize any selected one or ones of the magnets and punch up to eight holes in a single column A in tape 15. Thus, a one-for-one card column reading and tape column punching operation is effected.

Assuming that switch 18 is connected to contact N and that column B of the cards 11 and 12 is being sensed, it will be seen only the group of punches 1...4 associated with encoder 1 is now connected to ground through armature 22. Energization of a...
