PURPOSE:To obtain a device which facilitates counting operation by presetting unit weights of plural kind of articles, and accessing and using a necessary unit weight during counting operation. CONSTITUTION:Unit weights of plural kind of articles are preset, and the unit weight which corresponds to an article to be weighed is accessed selectively for weighing to calculate the number of weighed articles from weighing data obtained by weighing the articles and the accessed unit weight. For example, a CPU (central processing unit) 32 controls respective parts on the basis of program data in an ROM (read-only memory) 33, and this CPU fetches data from a scale part 35 through a data selector 36, inputs a key input from a keyboard 4 through a matrix circuit 37, and then receives data from a status input circuit 38 through a selector 39. Then, two decoders 40 and 41 are controlled to control a display part 42, and further a data latch circuit 43 is controlled to control a lamp turning-on circuit 44. |
