Abstract
In a ticket printer, an end of a paper sensor has an optic emitter and receiver arranged one after the other in the paper advancement direction and operationally connected together via a signal guide. The emitter and the receiver are arranged on one side of the path of the paper whereas the signal guide is arranged on the opposite side.
Claims12
A ticket printer, comprising
- (a) an advancing path in which a continuous strip of a printing support containing one of holes, notches and areas with lower reflective capacity relative to other areas of the strip is supplied in an advancing direction;
- (b) a cutting device for cutting the strip with transverse cuts in order to form printed tickets;
- and
- (c) a strip-end sensor comprising:
- (1) an emitter arranged for emitting a signal directed to a first zone of said advancing path in order to strike a first side of a strip that advances in said path;
- (2) a signal guide operationally facing a second side, opposite the first side, of a strip that advances in said path, said signal guide being configured for guiding the signal emitted by said emitter;
- and
- (3) a receiver arranged for receiving a signal that originates from said signal guide, wherein said signal guide is configured for guiding the signal along a signal path from said first zone to a second zone of said advancing path that is at a distance from said first zone, the distance between said first zone and said second zone having at least a component in said advancing direction, said receiver being arranged on an opposite part to said advancing path with respect to a part where said signal guide is arranged for receiving a signal that passes through said second zone in order to prevent a false end of paper signal due to the transit of one of a hole, a notch, and an area with lower reflective capacity relative to other areas of the strip in a detecting zone in which the strip-end sensor operates.
