Filed: 1989-12-13
Abstract: PURPOSE:To perform a proper performing in accordance with a subject working area via a robot by correcting the data on the lateral sliding extent in consideration of the situation every time the cleaning runs are carried on. CONSTITUTION:A memory card 30 is set to a cleaning robot and the room dimension data 31 on the card 30 is stored as a room dimension data 72. At the same time, the lateral sliding extent data 73 is calculated from the width of the inlet port of a cleaner 60. When a start switch 40 is turned on by an operator, a path planning means 74 plans the cleaning runs based on the data on a path data storing part 71. Then a longitudinal direction calculating means 75 calculates the longitudinal sliding extent of the robot started from a cleaning run start point based on the planned run.

Then the reciprocating frequency of the robot is divided by the logical reciprocating frequency when the robot reaches a cleaning end point. This division data is multiplied by the data 73 and then rewritten into the lateral sliding extent data 32 on the card 30.

Title: Copying interruption controller
Inventor: YAMAGAMI MASAFUMI
IPC: G03G15/00
Filed: 1991-11-12
Abstract: PURPOSE:To quantitatively determine a workload by judging 'interrupt enable' when the difference between the residual time required for copying calculated in accordance with the copying processing conditions under reservation and execution and the time required for next copying is larger than the prescribed time. CONSTITUTION:An operator inputs the preserved copying processing conditions, such as number of sheets of repetitive copying, sizes of copying paper and the number of sheets of originals, of the next copying processing by touching the reservation input key displayed on a liquid crystal display screen 413 as a reservation input means. A CPU 40 which is a means for calculating the time required for copying calculates the time required for copying of the next copying processing and the residual time required for copying of the copying processing under execution. The CPU 404 as a means for deciding 'interrupt enable' or 'disable interrupt' decides the 'interrupt enable' if the difference between the residual time required for copying and the time required for next copying is larger than the prescribed time. As a result, the occupying of the copying machine by the copying operator is averted and the conditions arising from the interrupt processing are switched in a short period of time, by which the efficiency of utilizing the copying machine is enhanced.
