Abstract
A hand-held printing calculator for printing calculating results on elongated paper strips from a bundle of paper strips disposed within the calculator is provided. The calculator includes a microprinter having a paper feeding assembly including feeding elements disposed before and after the print position and in the same plane as the advancing paper for maintaining the paper flat during printing. In another embodiment of the invention, a detection sensor detects the absence of a paper strip at the print position for generating a signal for feeding the next paper strip so that paper is continuously fed to the print position.
Claims5
A hand-held printing calculator for printing calculating results on paper strips stored flat within the calculator comprising:
- case means for defining an interior space and including paper storage means for storing a plurality of paper strips;
- calculator and printer circuit means within said interior space for performing calculating operations and generating corresponding print signals for printing the calculating results on a paper strip stored in said calculator;
- print means in said case means for printing on said paper strips in response to said print signals when one of the paper strips is in a print position adjacent said print means;
- paper advance means for continuously advancing a paper strip from the paper storage means to the print position, including first paper feeding means disposed before the print position and second paper feeding means disposed after the print position, said second paper feeding means advancing the paper strip at a faster rate than said first paper feeding means and the first and second paper feeding means disposed substantially in the same plane as the plane of the paper strip being advanced at the print position;
- and
- biasing means for biasing said paper strip towards said first paper feeding means.
