Abstract: A label printer prints article name together with required data such as weight, rate, price on a label adhered to products or packed products, or the label printer prints only the article name. Improved input means for article name, display means, date setting means for preparation date, check means for print head, label position detecting means in printing unit and memory adding means are disclosed.

Abstract: A bar code printer is disclosed which may be used as a standard desk type bar code printer, a weighing bar code printer, etc. by connecting outer peripheral equipment, such as weighing instruments or price indicating balances, to the bar code printer. A change-over circuit can select an input signal from either the input unit of the bar code printer or from the outer peripheral equipment, the input signal energizing a control circuit which develops control signals to drive a bar code printing system and an indicating system. The printer has differing types of bar code systems stored therein and by entering a flag code, a specific bar code system may be selected. Also, the differing types of bar code systems may be accommodated since the bar code is divided into a fixed part (for common use in all systems) and a variable part (differing numerals between bar code systems).

Abstract: Printing control apparatus includes structure for selectively preventing the operation of a thermal head comprising part of a label printer for thermosensitive labels. The thermal head can be moved away from and into contact with a label to limit its operational printing period. Alternately, thermal elements comprising a portion of the thermal head can be deactivated when a label detector fails to detect the presence of a label at a predetermined position, when the contact between the thermal head and a label is inadequate, or when the transportation or feeding of the label over a predetermined path within the printer is abnormal. A method for using the apparatus to selectively prevent the thermal head from being operational is also provided. A thermosensitive label is adapted to be used in conjunction with the apparatus and method and includes a substrate layer and a thermosensitive coloring layer comprising a color former and a transparent dye.

Abstract: In a display holding device for an electronic digital display type scale, when a part of a first load applied to the weighing section is removed therefrom, a hold signal is automatically outputted so that the data representative of the weight, price, etc., of the first load, which have been displayed by the data display sections before the removal of the part of the first load, are maintained displayed for a predetermined period of time, and displaying the data is released automatically, or when a predetermined key is operated, or when a second load is nextly applied to the weighing section.

Abstract: An automatic unit price setting apparatus for an electronic digital display scale with a printing device in an equipment adapted to compute and display a price of an article of goods by multiplying a weight of said article to be weighed by a unit price of the article when the unit price is inputted in said scale and to print the name, weight, unit price and price of said article to be weighed, wherein one of a plurality of stamps for printing the names of articles engraved thereon is selectively connected with a unit price setting section of said electronic digital display scale so that said stamp and unit price setting section are electrically operated, and the unit prices of said articles indicated on said stamps are automatically set on the scale by operating said stamps.

Abstract: An electronic digital display scale with a label printer adapted to weigh an article, to print a measured weight of said article on a label and to adhere said label onto said article weighed, wherein the printed label is held by a label transfer device by means of adhering or suction and transferred to an applying position outside a frame, thereby said label is applied to the weighted article by depressing said weighed article against the label retained by said label transfer device.
