| 20080209741 | Blade structure of an electric hair trimmer - A blade structure of an electric hair trimmer is a blade set, comprising a fixed blade, a movable blade and a vibration seat which is driven by a motor. A front end of both fixed and movable blades is provided with a plurality of teeth to cut the hair by an alternate movement. The lower sections of edge parts at two sides of a tooth of the movable blade are extended outward from top to bottom to form with externally expanded surfaces with sharp transection angles. Accordingly, when hair is cut, a contact area of the edge parts between the hair is decreased, to largely reduce resistance to cutting, such that the hair can be cut off well with improved speed and efficiency and can be prevented from being damaged. Besides, lifetime of usage of blade structure in the electric hair trimmer can be extended. | 09-04-2008 |
| 20110302789 | Hair Trimmer - A hair trimmer includes a fixture having an upper and a lower tie plates, with an elastic element between the upper and lower tie plates; at least two cutting units at an end of the upper and lower tie plates, with each cutting unit having a corresponding cutting part, and an end of each cutting part having notches of different depths; and at least two combing units assembled with the upper and lower tie plates and corresponding to an exterior side of each cutting unit, with each combing unit including a teeth part which corresponds to each other and is parallel to the cutting part, and an end of each teeth part having comb slots of different depths. Therefore, a multiedged thinning can be carried out while trimming and it allows the hair to have more different levels of edge and a sense of beauty. | 12-15-2011 |

| 20080232888 | Ink ribbon cartridge for a label printer - An ink ribbon cartridge is used in a label printer, including: a frame having two opposite side boards, a top board, and a bottom board, of which the top and bottom boards are mounted to top and bottom ends of the side boards; two first pivots respectively mounted to opposing surfaces of the opposite side boards and horizontally opposite to each other; two second pivots respectively mounted to the opposing surfaces of the opposite side boards and horizontally opposite to each other, the second pivots being arranged lower than the first pivots; and two channel structures including two first guides and two second guides, which are formed on the opposing surfaces of the opposite side boards and opposite to each other so as to delimit the two channel structures for guiding a printing module of the label printer along the channel structures for coupling to the ink ribbon cartridge. | 09-25-2008 |
| 20080232890 | Movable print head for a label printer - A movable print head is provided for a label printer, including: a control panel module having two pivots arranged on opposite sides of the control panel module and coupled to opposite sides of a body of the label printer to serve as rotational center for rotation of the control panel module; and a printing module fixed to an internal vertical surface of the control panel module and including two guide-in devices on opposite sides of the printing module to guide in an ink ribbon cartridge and a print head arranged between the two guide-in devices. The two guide-in devices of the printing module are movable in unison with the rotation of the control panel module to effect movable adjustment for guiding in the ink ribbon cartridge. | 09-25-2008 |
| 20090238628 | Printing mechanism of barcode printer - 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. The carbon ribbon from the carbon ribbon axle can be wound around and collected by the carbon ribbon collection axle in a shortest path. Thus, a printing mechanism featuring a reduced length of carbon ribbon collection path and a reduced size is provided. | 09-24-2009 |
| 20090238629 | Barcode label retention device of barcode printer - 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. | 09-24-2009 |
| 20090238630 | Label roll positioning device of barcode printer - A label roll positioning device is provided for a barcode printer and includes at least one slide rail, at least one positioning rail, and at least one pair of roll retainers. The slide rail and the positioning rail are arranged in a parallel manner inside a housing of the barcode printer. The positioning rail forms teeth on a surface thereof. At least one of the roll retainers has a bottom forming a mounting portion that is slidably fit and mounted to the slide rail for being slidable along the slide rail. The roll retainers are spaced to receive a roll of label therebetween in a securely held manner. The roll retainer is provided therein at least one positioning plug having an end forming a locking section. The positioning plug can be downward driven to have the locking section downward projecting out of the roll retainer, and the positioning plug can be upward driven to have the locking section back into concealment inside the roll retainer. Thus, with the roll of label received between the roll retainers, the positioning plug is downward driven and the locking section engages the teeth of the positioning rail to effect positioning and fixing for securely holding the roll of label between the roll retainers. A positioning device with movable and adjustable locking engagement can be realized. | 09-24-2009 |
| 20090279932 | Carbon ribbon retaining mechanism - A carbon ribbon retaining mechanism includes a barcode-printer base, an upper cover, a printing head device, and at least one pair of resilient fastener elements. The barcode-printer base has an upper portion forming a receiving space. The upper cover is coupled to the receiving space of the barcode-printer base for being downward closed to and covering the receiving space. At least one pawl is respectively formed on opposite edge portions of the upper cover. The printing head device is accommodated in the receiving space. A carbon ribbon retention shaft is arranged above the printing head device. The resilient fastener elements are mounted above the printing head device. By means of the engagement effected between the pawls of the upper cover and the resilient fastener elements, the upper cover is fixed to and above the printing head device to cover the receiving space. Further, by flapping the upper cover upward, the pawls of the upper cover are disengaged from the resilient fastener elements to allow opening of the upper cover and thus expose the carbon ribbon retention shaft for replacement and/or maintenance. | 11-12-2009 |
