Antijamming device for printers put in public places

An antijamming device for a printed ticket vending machine having an exit opening for exiting of a printed ticket and control means including a motor for controlling feeding of paper from a paper roll to a printing mechanism for printing tickets, comprising:

• a pathway including a duct through which the paper moves through which said ducts printed tickets pass from said printing mechanism to said exit opening;
• a sensing means including a rise positioned within said duct and a contact movable arm in said duct movable between a pair of contacts for deactivating the feeding of paper from said roll to said printer mechanism when said rise causes paper to engage and contact said contact movable arm when said occlusion occurs to cause said contact movable arm to move from one position connecting said pair of contacts to another position for disconnecting of said pair of contacts in response to the occlusion occurring at the exit opening and a back-up of printed tickets occurring at said rise to stop the motor from feeding paper from said paper roll when an occlusion occurs;
• said control means including said sensing means located within said pathway for sensing when the occlusion occurs at said exit opening solely to prevent bunching of the printed tickets at said exit opening and stopping feeding of the printed tickets to said exit opening;
• and said rise including a protrusion integrally formed in said pathway positioned perpendicular to the feeding direction of the paper and opposingly to said contact movable arm as to cause the paper to bend around said rise.
