Abstract: PURPOSE:To check whether the rejection of a defective article is exactly executed or not by providing a defective article rejection detecting means to detect whether the defective article is rejected and moved to the prescribed rejection point or not and to output an alarm signal when the rejection movement is not executed. CONSTITUTION:The rejection signal (a) for the detective article 3a is sent to a defective article rejection device 1 as a result of the checking by an X-ray level checker 2. The light from a light projector 4a of a photoelectric switch 4 is not shut off by the defective article 3a when the defective article rejection device 2 fails to make the normal rejection of the defective article 3a. A rejection detection signal (c) is, therefore, not emitted. A gate circuit 6 is consequently not set and a gate signal (d) attains a HIGH level. The decision state of a decision circuit 7 turns to abnormal decision and the circuit generates an abnormal decision signal (f). An alarm signal generating circuit 8 operates upon receipt of this signal and generates the alarm signal (g). The presence of the abnormality in the defective article rejection action is announced to an operator by using the alarm signal (g) for generating an alarm sound and displaying an alarm message. The signal is otherwise used for the automatic stop of the production line or the like.

Title: Record medium and device for two-dimensional code data conversion and printer
Inventor: MIYASHITA TOMOMOTO
IPC: G06K19/06
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To facilitate the operator's operation when before-conversion information data as a set of pieces of character data are converted into >=2 pieces of two-dimensional code data. SOLUTION: The before-conversion information data are divided and converted into two-dimensional code data by the pieces of before-conversion information data. It is decided (S18) whether or not the code symbol of a two-dimensional code represented by the two-dimensional code data is larger than a set maximum value and when so, the number of divisions is increased (S19). Then the before-conversion information data is divided by the increased number of divisions and similar implementation is repeated. Thus, the before-conversion information data is automatically divided, so as operator needs not divide it and the operation at the time of the two-dimensional code data conversion is easily performed.  Further, the data are converted so that the code symbol does not exceed the set maximum value, so the two-dimensional code is printed effectively on an output medium whose width direction of a tape is limited.
