Claims
- 1. A hand-held labeling machine comprising; a housing having a manually engageable handle, the housing having means for holding a label supply roll of a composite web having labels releaseably adhered to a backing strip, means for connecting a first source of electrical energy to said labeling machine, an on-off switch interposed between said connecting means and said labeling machine and having a first terminal coupled to said connecting means and a second terminal coupled to said labeler, means for printing on a label at a printing position, means for peeling the printed label from the backing strip, label applying means disposed adjacent the peeling means, means for advancing the web to peel a printed label from the backing strip at the peeling means and advance the printed label into label applying relationship with the label applying means and to advance another label into the printing position, means for entering selected data to be printed, the printing means including a thermographic print head having a plurality of individually selectable print elements powered by the source of electrical energy for printing on a thermographic label at the printing position, means coupled to said data entering means for electrically processing the selected data and energizing the individual print elements in a predetermined sequence determined by the selected data to print data on the label, said processing means including memory means of the type requiring the continuous application of electrical energy thereto to maintain the memory function, circuit means having first means electrically coupled to said second terminal for automatically applying electrical energy from said source to said labeling machine and said memory means when said on-off switch is on, said circuit means having second means electrically coupled to said first terminal for automatically applying electrical energy from said source to said memory means when said on-off switch is off, said circuit means further including third means electrically coupled to a second source of electrical energy for automatically applying electrical energy from said second source of electrical energy to said memory means when said first source is inoperative or disconnected from said labeling machine, said circuit means including isolation means for isolating said first, second and third means so that said second source of electrical energy is operative to provide electrical energy only to said memory means.
- 2. A hand-held labeling machine as recited in claim 1 wherein said first, second and third means are operative to provide three different voltages to said memory means.
- 3. A hand-held labeling machine as recited in claim 2 wherein said first means is operative to provide the highest voltage to said memory, said second means is operative to provide an intermediate voltage, and said third means is operative to provide the lowest voltage.
- 4. A hand-held labeling machine as recited in claim 1 wherein said isolation means includes a plurality of diodes.
- 5. A machine comprising; a housing having means for holding a label supply roll of a composite web having labels releaseably adhered to a backing strip, means for connecting a first source of electrical energy to said labeling machine, an on-off switch interposed between said connecting means and said labeling machine and having a first terminal coupled to said connecting means and a second terminal coupled to said labeler, means for printing on a label at a printing position, means for peeling the printed label from the backing strip, label applying means disposed adjacent the peeling means, means for advancing the web to peel a printed label from the backing strip at the peeling means and advance the printed label into label applying relationship with the label applying means and to advance another label into the printing position, means for entering selected data to be printed, the printing means including a thermographic print head having a plurality of individually selectable print elements powered by the source of electrical energy for printing on a thermographic label at the printing position, means coupled to said data entering means for electrically processing the selected data and energizing the individual print elements in a predetermined sequence determined by the selected data to print data on the label, said processing means including memory means of the type requiring the continuous application of electrical energy thereto to maintain the memory function, circuit means having first means electrically coupled to said second terminal for automatically applying electrical energy from said source to said labeling machine and said memory means when said on-off switch is on, said circuit means having second means electrically coupled to said first terminal for automatically applying electrical energy from said source to said memory means when said on-off switch is off, said circuit means further including third means electrically coupled to a second source of electrical energy for automatically applying electrical energy from said second source of electrical energy to said memory means when said first source is inoperative or disconnected from said labeling machine, said circuit means including isolation means for isolating said first, second and third means so that said second source of electrical energy is operative to provide electrical energy only to said memory means.
- 6. A hand-held labeling machine comprising; a housing having a manually engageable handle, the housing having means for holding a label supply roll of a composite web having labels releaseably adhered to a backing strip, means for connecting a first source of electrical energy to said labeling machine, an on-off switch interposed between said connecting means and said labeling machine and having a first terminal coupled to said connecting means and a second terminal coupled to said labeler, means for printing on a label at a printing position, means for peeling the printed label from the backing strip, label applying means disposed adjacent the peeling means, means for advancing the web to peel a printed label from the backing strip at the peeling means and advance the printed label into label applying relationship with the label applying means and to advance another label into the printing position, means for entering selected data to be printed, the printing means including a thermographic print head having a plurality of individually selectable print elements powered by the source of electrical energy for printing on a thermographic label at the printing position, means coupled to said data entering means for electrically processing the selected data and energizing the individual print elements in a predetermined sequence determined by the selected data to print data on the label, said processing means including memory means of the type requiring the continuous application of electrical energy thereto to maintain the memory function, circuit means having first means electrically coupled to said second terminal for automatically applying electrical energy from said source to said labeling machine and said memory means when said on-off switch is on, said circuit means having second means electrically coupled to said first terminal for automatially applying electrical energy from said source to said memory means when said on-off switch is off, said circuit means further including third means electrically coupled to a second source of electrical energy for automatically applying electrical energy from said second source of electrical energy to said memory means when said first source is inoperative or disconnected from said labeling machine, said circuit means including isolation means for isolating said first, second and third means so that said second source of electrical energy is operative to provide electrical energy to said memory means.
