The pressure adjusting knobs serve to adjust pressure for positioning in the upward-downward direction of a label sheet of the barcode printer. The universal adjusting knob functions to realize fine adjustment of pressure for positioning in a universal adjustable manner that the pressure regulation seat applies to the label sheet. At least one universal adjusting mechanism is coupled to bottom of the pressure regulation seat for effecting adjustment of inclination direction by the universal adjustment realized by the universal adjusting knob. At least one printing head holder is coupled to a front portion of the universal adjusting mechanism and has a bottom coupled to a printing head, whereby the printing head holder is subjected to adjustment of pressure in upward-onward direction by the pressure adjusting knobs of the pressure regulation seat and is also subjected to fine adjustment of inclination direction by the adjustment that the universal adjusting knob applies to the universal adjusting mechanism to effect universal fine adjustment for the printing head holder and the printing head in order to ensure tight engagement of the printing head with respect to the label sheet of the barcode printer. Thus, a label sheet positioning device featuring universal fine adjustment of inclination direction is provided. | 07-09-2009 |
20090174139 | Label sheet out-feeding detection device for barcode printer - A label sheet out-feeding detection device is provided for a barcode printer and includes a guide member coupled to a front enclosure of the barcode printer. The guide member forms at least one pair of opposing rails. Two casing members are combined to each other to form a combined casing movably received between the rails of the guide member for conducting up and down movement. The combined casing has a top portion forming a detection channel. A guide rail is formed inside the casing. A least a pair of photo-electric detection elements is respectively mounted on wall portions of the casing respectively above and below the detection channel for detecting out-feeding of a label sheet passing through the detection channel. At least one resilient device has an end coupled to the guide member and an oppose end engaging a bottom portion of the casing. At least one positioning bar has an end pivotally jointed to the guide member and an opposite end forming a positioner fit into and movably received in the guide rail of the casing. When the casing is depressed, the location of the positioner of the positioning bar within the guide rail is changed. The casing is selectively and resiliently raised up for conducting detection or depressed down for being concealed inside the casing. Thus, a label sheet out-feeding detection device that is switchable between an operation condition and a concealed and stowed condition by means of depression is realized. | 07-09-2009 |
20090174140 | Retention device of barcode printer - A roller retention device is provided for a barcode printer and includes a base and at least one peeling board, wherein the base is mounted to an enclosure of the barcode printer. The base has a front portion forming at least one first channel for accommodating a rear portion of a label sheet hold-down roller of the barcode printer.
