Abstract: An optical grain evaluation device is provided with: a light-projecting part 58 through which light from a light source is projected to grain; a light-receiving part 59 on which light transmitted through the grain is incident; a grain evaluation unit 60 configured to evaluate the grain based on information relating to the received light; and a shielding part SH that separates an area between the light source 50 and the light-projecting part 59 from an area between the light-receiving part 59 and the grain evaluation unit 60, and prevents light from the light-projecting part 58 from directly entering the light-receiving part 59. The area between the light source 50 and the light-projecting part 58, and the area between the light-receiving part 59 and the grain evaluation unit 60 are configured, over the entirety of the areas, as air transmission areas in which light is transmitted through air.

Abstract: A computing scale with a label issuing system comprises an electronic weighing portion employing a load cell of a strain gage type and a label issuing portion. The label issuing portion comprises a printer for printing a weight value, price and the like on labels. The printer is spaced apart from a base or chassis by a very small gap. A rolled-up sheet supporting portion for supporting a label retaining backing sheet rolled-up and a winding portion for winding up the backing sheet from which labels have been stripped are provided rearward of the printer. The labels are subjected to printing of the weight and the like by the printer based on the data obtained from the weighing portion and stamping of the item by means of a stamping portion and are then substantially stripped, with a minor portion thereof retained to the backing sheet, by means of a stripping portion provided forward of the printer, whereupon each of the labels is manually removed from the backing sheet.
