Abstract: The present invention relates to a packing method and an apparatus, wherein a substance to be packed is carried from a carrying-in section in which the substance is carried to a position under a packing section where a film stands by in a horizontally stretched state. The substance to be packed is lifted to the film and is covered on the upper surface with the film, and the end portions of the film are folded under the bottom portion of the substance to be packed. The packing method and packing apparatus are for a no-tray system for directly packing a substance to be packed without a tray.

Abstract: The present invention provides an improved printer head for using a detachable cassette, particularly the printer head stationary mounted on a print station for using a detachably loadable cassette on the station, the cassette integrally having a webbed label together with a platen roller therein. In prior art, however, a conventional printer head is disadvantageous that a webbed label is often broken during the replacement of the cassette due to the absence of suitable locking mechanism to refuge the printer head from a platen roller so as to facilitate and ensure the safe replacement of webbed label when the cassette is replaced. In order to solve such disadvantages, the present invention provides an improved printer head capable of constantly being held at a position apart from a platen roller to refuge in the upper portion as far as no cassette is loaded on the print station.

Abstract: The label printer comprises at least two printing units and a control unit. Each printing unit can print a specific label under the control of the control unit. The label is printed with information concerning a commodity, such as a price and a weight of the commodity. One or two printed labels are attached at predetermined positions on the commodity. Further, the two printing units can be moved so that each printing unit can attach each printed label on the commodity.
