ABSTRACT:
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.
