Adjustable-Width Paper Guillotine Mechanism

Printers designed for point-of-sale terminal application usually involve a continuous-receipt paper-handling mechanism. Customer receipts are usually torn off and presented to the customer.

A guillotine knife assembly may be utilized where more accurate cut-off is desired. This reduces pulling the paper off the feed roll or over-tensioning the paper web, causing jams or misfeeding in the mechanisms. However, it is not desired to totally cut off some receipts since they may drop or be lost. The adjustable guillotine mechanism permits cutting off the receipt from 100% to about 90% of its width in adjustable steps selected by the operator. The small portion of uncut receipt paper serves to hold the receipt in place until the operator tears off the small portion remaining. Fig. 1 illustrates an oblique pictorial schematic of the back side of the mechanism. A stationary guillotine blade 1 is positioned above a feed slot 2 and is attached to a slide mechanism that will be described later. The slide mechanism has a base plate 4 provided with slots 5 fitting over studs 6 and retained by retaining washer 7.

The base 4 may be reciprocated back and forth along the direction of the slots 5, carrying with it the stationary blade 1 and a movable blade 3 (not shown). A series of serrations 8 in the bottom of slide base 4 interact with a pawl 9 that is spring biased by spring 10 pushing against stop 11 to releasably hold the slide base...
