Abstract
An automatic opening device for a printer having an openable/closeable gate for providing access to a printer housing for housing a paper roll onto which information is to be printed and housing other printer parts, comprising a rotatable shaft for carrying a printer roll for printing onto paper carried by a paper roll in the printer housing a sensor operatively associated with the paper roll for sensing when the end of the paper carried by the paper roll is reached, a gate lifting mechanism coupled to the gate to lift the gate for opening the printer housing to provide access to the paper roll, and an arrangement responsive to the sensor when sensing the end of the paper to operate the gate lifting mechanism to open the gate for providing access to the paper roll to change the paper.

An automatic opening device for a printer having an openable/closeable gate for providing access to a printer housing for housing a paper roll onto which information is to be printed and other printer parts, comprising:
- a rotatable shaft for carrying a printer roll for printing onto paper carried by said paper roll housed in the printer housing;
- a sensor operatively associated with said paper roll for sensing when the end of the paper carried by said paper roll is reached;
- a gate lifting mechanism coupled to said gate and responsive to said sensor for lifting said gate to open the housing for the printer for providing access to the paper roll housed in said printer housing when an end of the paper on said paper roll is reached;
- and
- means responsive to said sensor for sensing when the end of the paper on the paper roll contained within said housing is reached for enabling access to said paper roll to be provided for permitting removal of said paper roll and replacement thereof and cooperating with said gate lifting mechanism for rendering said gate lifting mechanism operable to cause said gate lifting mechanism to raise said openable/closeable gate in response solely to said sensor sensing when the end of said paper is reached.
An automatic opening device for a printer having an openable/closeable gate for providing access to a printer housing for housing a paper roll onto which information is to be printed and for housing other printer parts, comprising:
- a rotatable shaft for carrying a printer roll for printing onto paper carried by said paper roll in the printer housing;
- a sensor including an unidirectional bearing arrangement responsive to said sensor for sensing when the end of the paper carried by said paper roll is reached and for providing access to said printer housing;
- a gate lifting spring operated mechanism to lift said gate to open the housing for the printer for providing access to the paper roll housed in said printer housing;
- means responsive to said sensor when sensing the end of the paper on the paper roll contained within said housing for providing access to said paper roll for permitting removal thereof and cooperating with said gate lifting spring operated mechanism for rendering said gate lifting mechanism operable to raise said gate.
