Abstract
The device () for detecting end of paper comprises a support () mounted on a wall () of a printer () of receipts, obtained from a tape () of paper wound on a roll (), contained in a housing () of the printer (). The printer () is preferentially employed at a Point Of Sale (POS) and may be arranged on a horizontal work plane () set on its base (), or inclined by about 90°, on a front wall (). As a result, the roll () is set into the housing () alternatively in two positions, corresponding to the inclination assumed by the printer. A detecting lever () in hinge-mounted on the support () and is provided with two arms () spread apart, forming an angle of approximately 120°. Fixed to each of the ends of the arms () is a projecting element (), each of which suitable for engaging a hole in a central sprocket () of the roll (), when the latter has reached its minimum dimension, in which a given length of tape remains of the sprocket (), indicating that the latter is closed to running out. The two projecting elements () are positioned in such a way that only one of these enters the hole in the sprocket (), when the printer () is set in one of the two positions; the support () is moved linearly on the wall () by way of a toothed cam (), in order to adapt the position of each of the projecting elements to the dimensions of the sprocket () of the paper roll.
