Coin-controlled Lock (e.g., Responsive To Print-lines, Time, Etc.) Patents (Class 400/673)
  • Patent number: 4359939
    Abstract: Herein disclosed is such a printing device to be used with a hand labeler or the like that is enabled to prevent a printing medium, such as labels or tags, from being thinly printed and so that averaged clean prints may be made at all times. The printing device includes an actuating lever for bringing a printing head into and out of engagement with a printing medium so that the printing medium may be imprinted. A counting mechanism cooperates with the actuating lever for counting the number of prints. When the counting mechanism counts a predetermined number of prints, a print stopping mechanism stops the operation of the actuating lever. A print returning mechanism releases the stopped condition of the actuating lever so that the printable condition may be restored.
