Abstract
A paper web take-up and storage device for a teleprinter, having a spring biased guide bail to sense paper length and a control switch that energizes a storage reel drive motor for take-up when needed, is also equipped with a paper sensor arm to detect a no-paper condition; a single switch actuator lever that is aligned with the bail, with the sensor arm, and with the control switch affords complete control for both take-up and no-paper conditions in an arrangement that allows limited reverse movement of the web back toward the printer with no appreciable resistance apart from a relatively weak bail bias spring. The reel includes a spring-latched guide flange adjustable to accommodate a number of different paper widths.
