Patent number: 8182162Abstract: A barcode label retention device is provided for a barcode printer. The barcode label retention device includes s at least one pair of label roll retainers, at least one pair of resilient elements, and at least one pair of fixing plates. The label roll retainers are mounted inside a housing of a barcode printer and spaced from each other to receive and retain a label roll therebetween. The resilient elements are arranged inside each label roll retainer, and the fixing plates are arranged inside each label roll retainer. The fixing plate is connected to the resilient element to provide the fixing plate with resiliency for inward depressibility or outward biasing so that a front portion of the fixing plate projects inwards beyond the label roll retainer to abut against opposite ends of the label roll, whereby the label roll can be securely held by the two fixing plates engaging the opposite ends thereof and the path of a winding/unwinding operation can be stabilized.Type: GrantFiled: March 19, 2009Date of Patent: May 22, 2012Assignee: TSC Auto ID Technology Co., Ltd.Inventors: Shang-Shih Kuo, Chin-Chuan Liu

Publication number: 20090238628Abstract: A printing mechanism is provided for a barcode printer and includes a frame, a printing head, a carbon ribbon axle, and a carbon ribbon collection axle. The frame is mounted to an upper end portion of an upper casing member. The printing head is mounted in the frame to effect printing of labels. The carbon ribbon axle is arranged in a lower portion of the frame and is located below the printing head for connecting and retaining a carbon ribbon that supplies a toner required for carrying out the printing of the labels by the printing head. The carbon ribbon collection axle is arranged in an upper portion of the frame and is located above the printing head in an arrangement that is reversed to the carbon ribbon axle to allow the carbon ribbon from the carbon ribbon axle to be rolled up in the carbon ribbon collection axle after the printing operation carried out by the printing head.Type: ApplicationFiled: March 20, 2009Publication date: September 24, 2009Inventors: Shang-Shih Kuo, Chin-Chuan Liu
