Filed: 1989-07-17
Abstract: PURPOSE:To accurately perform toner end detection and toner supply by comparing the oscillation frequency of a toner detection sensor which is counted at every interval of a constant time with set values and judging the supply and end state of toner. CONSTITUTION:A control part 26 compares the oscillation frequency (n) of the toner detection sensor 23 which is counted at every interval of the constant time with values (n1, n2, and n3) indicating toner remaining values to supply toner until n>n1 and judges the toner end state when n<n3. Then when toner deceases in amount in the time T of one turn of a toner agitation member, the oscillation time (t) of the toner detection sensor 23 in the time T becomes long, so the oscillation frequency (n) corresponding to the time is counted. Consequently, the detection of the toner end state and the toner supply are accurately performed.

Abstract: PURPOSE:To increase the calculating speed by means of a simple computer in the nearmiss checking method for robots by returning an arithmetic operation to a known interference check calculation against a model which is magnified by an extent equal to a safe distance. CONSTITUTION:In a step S1, the relationship is previously set among a robot, the movement data D1 and D2 on the objects existing in a movable range of the robot, and a safe distance L. The distance L can evade the nearmiss among these robot and objects. In a step S2, the models M1 and M2 which envelope the robot and the objects are produced. In a step S3, both data D1 and D2 are inputted. In a step S4, the distance L is calculated based on the input data D1 and D2 and the relationship X and also the sizes of the robot and the objects are magnified by an extent equal to the distance L. In a step S5, the interference check is carried out in the sizes of the magnified models M1' and M2' so that the nearmiss is checked among the robot and the objects. Thus it is possible to perform an arithmetic operation at a high speed for the nearmiss check by means of a simple computer.
