## Abstract

It is disclosed an anti-jamming device for a printing apparatus with stacker, for lottery or betting terminals, with a path of a continuous strip of paper, a printing device for printing a document on the strip, a cutting device for separating the document from the strip, a movement device for moving the document laterally to a stacking zone, a movable portion that bounds the path and is moved from the strip in the event of a jam, moving the portion causing printing to be stopped.

## Claims

### Claim 1

A printing apparatus comprising:
a path for a continuous strip;
a printing device for printing a document on the strip;
a cutting device for separating the document from the strip when the document is in a cutting position;
a movement device for moving the document from said cutting position to a stacking position, said movement device comprising a pusher that moves the document laterally from said cutting position to said stacking position;
an anti-jamming device comprising a movable portion that can adopt a normal position, in which it is arranged on one side of a part of said path, and an anomalous position, in which it is moved away from said part of said path, a movement of said movable portion from said normal position to said anomalous position being caused by a push of the strip that is deformed laterally because of an irregularity on said path;
a control arrangement for stopping the advancement of the strip and stopping said printing device when said movable portion adopts said anomalous position.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein said movable portion is arranged before said movement device, with reference to an advancement direction of the strip along said path to said cutting position.

### Claim 3 (depends on 1)

The apparatus according to claim 1, wherein said movable portion is arranged after said cutting device, with reference to an advancement direction of the strip along said path to said cutting position.

### Claim 4 (depends on 1)

The apparatus according to claim 1, in which:
said cutting device is arranged below said cutting position and below said movable portion;
the strip advances with a tilted direction upwards from a start to an end of said part of said path;
said movable portion is tilted and has a lower end nearer said cutting device and an upper end further from said cutting device;
said upper end is hinged and said lower end is free and rests against an abutment, a movement of said movable portion from said normal position to said anomalous position comprising a rotation around said upper end.

### Claim 5 (depends on 1)

The apparatus according to claim 1, in which said anti-jamming device comprises a sensor arrangement for detecting said anomalous position of said movable portion.

### Claim 6 (depends on 5)

The apparatus according to claim 5, wherein said sensor arrangement comprises at least one switch.

### Claim 7 (depends on 1)

The apparatus according to claim 1, in which said printing device comprises a printing head and a printing roller coupled frontally with said printing head, said printing roller making the strip advance as far as said cutting position.

### Claim 8 (depends on 1)

The apparatus according to claim 1, said pusher being arranged in contact on a face of the document for pushing in a direction that is transverse to said face, said pusher having a reciprocating motion with an outward stroke to move the document laterally to said stacking position and a return stroke for returning to a position that is suitable for moving the next document laterally.

### Claim 9 (depends on 1)

The apparatus according to claim 1, comprising at least one movable stacking wall having an elastic arrangement for maintaining pressed the document situated in said stacking position against an abutting arrangement, said stacking wall being arranged for retracting, in opposition with said elastic arrangement, pushed by said movement device when the latter moves the document from said cutting position to said stacking position.

### Claim 10

A printing method comprising the steps of:
printing a document on a strip that advances along a path by means of a printing device;
separating the document from the strip by means of a cutting device;
moving the document to a stacking position by means of a pusher that moves the document laterally to said stacking position;
interrupting an advancement of the strip and stopping said printing device if a movement is detected of a movable portion that is arranged adjacent to a part of said path arranged downstream of said cutting device, said movement being caused by the push of the strip that is deformed laterally because of an irregularity on said path.

### Claim 11

A printing apparatus comprising:
a path for a continuous strip;
a printing device for printing a document on the strip;
a cutting device for separating the document from the strip when the document is in a cutting position;
a movement device for moving the document from said cutting position to a stacking position, said movement device comprising a pusher that moves the document laterally from said cutting position to said stacking position, said pusher being arranged in contact on a face of the document for pushing in a direction that is transverse to said face, said pusher having a reciprocating motion with an outward stroke to move the document laterally to said stacking position and a return stroke for returning to a position that is suitable for moving the next document laterally;
an anti-jamming device comprising a movable portion that can adopt a normal position, in which it is arranged on one side of a part of said path, and an anomalous position, in which it is moved away from said part of said path, a movement of said movable portion from said normal position to said anomalous position being caused by the strip that is deformed laterally because of an irregularity on said path;
control arrangement for stopping the advancement of the strip and stopping said printing device when said movable portion adopts said anomalous position.
