Abstract

This publication describes an automatic indexing guide for a PORT-A-PUNCH device. The latter enables a user to manually punch holes in a card to provide a readable code. The card is mounted in frame 10 below an apertured plate which permits access to the row and column positions of the card. Overlay card 12 with a printed text identifying the information to be recorded in a particular column is placed over the apertured plate. The user punches holes in the desired location by hand-held stylus 14.

Indexing Guide for Port a Punch

This publication describes an automatic indexing guide for a PORT-A- PUNCH device. The latter enables a user to manually punch holes in a card to provide a readable code. The card is mounted in frame 10 below an apertured plate which permits access to the row and column positions of the card. Overlay card 12 with a printed text identifying the information to be recorded in a particular column is placed over the apertured plate. The user punches holes in the desired location by hand-held stylus 14.

In some applications there is a great deal of information contained on overlay card 12 which can lead to a high incidence of error because of mispunching and due to overlooking some columns. The indexing guide is used in conjunction with the PORT-A-PUNCH device that acts as a guide to help identify the columns being used. At the same time, it provides for automatically moving the guide to the next column when information is punched in the column.

Guide 16 is a narrow element that extends along the width of overlay card 12 and is made of clear tinted plastic. Guide 16 has a rectangular window cut from its center to allow access to two columns of the punch. Fixed to the top of the flat guide is a curved piece of plastic 18. When stylus 14 is used to punch a hole in one column, the tapered portion of such stylus exerts a lateral force on plastic 18 of guide 16 causing it to move to the next column position.

Thus, guide 16 allows for multiple...
