Abstract

It is often desirable for labels and the like to have a printed legend and, also, a magnetic encoded stripe. The drawing shows a magnetic stripe encoding apparatus and a paper feed apparatus that can be combined with an otherwise independent printer to prepare these labels.

Magnetic Encoder for Printer Terminal

It is often desirable for labels and the like to have a printed legend and, also, a magnetic encoded stripe. The drawing shows a magnetic stripe encoding apparatus and a paper feed apparatus that can be combined with an otherwise independent printer to prepare these labels.

The magnetic stripe encoder is shown in detail in the IBM Technical Disclosure Bulletin, Vol. 19, No. 5, October 1976, pp. 1808, 1809. The encoder of the drawing has a frame 2 with an upper horizontal plate 3 that supports a label which carries a magnetic stripe. A linear stepping motor 5 drives an encoding head 6 across the label for the stripe-encoding operation. A plate 7 provides a backing support for the label.

The labels which have an adhesive backing, are carried by a web of paper that is perforated so that, after the labels have been printed and encoded, they can be assembled in units of a convenient size. The magnetic stripe is conventionally oriented in the lengthwise direction of the web. The encoding head 6 can be shifted on its support to accommodate labels that have this stripe located at any position. The paper web also has spaced holes along each side for engagement by pins 8 of web-feed tractor 9 which is driven by means of a digitally-controlled stepping motor (not shown). The magnetic encoding unit is located as close as possible to the printer and does not require a separate source of power for advancing the labels beyond the encoding position. The path of the web is shown in the drawing by a dashed line. As labels are magnetically encoded and printed, the web is pulled from a supply hopper (not shown) over the plate 3, past the platen 10 and the print head 11 of the print station, over a wire supporting guide 12, and to a receiving station (not shown).

The magnetic encoder is spaced from the printer so that one label is positioned fo...
