Title:
TRAVELING OBJECT CONTROLLER
Document Type and Number:
Japanese Patent JP3238110
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To quickly and surely detect the position of a traveling object and to smoothly control the traveling object.
SOLUTION: Along the moving direction of the traveling object 1, traveling object stop positions (1)-(4) are set. Plural switches 2a, 2b and 2c are provided on the traveling object 1 and are pressurized so as to be turned to an ON state by projection parts 3a, 3b and 3c for pressing the switches by patterns different for the respective traveling object stop positions (1)-(4). A state where the traveling object 1 is present in the moddle of the moving object stop positions (2) and (3), all of the switches 2a, 2b and 2c are not pressurized by the projection parts 3a, 3b and 3c for pressing the swishes and all are OFF is detected, and when the detection pattern of the switches 2a, 2b and 2c corresponding to the next traveling object stop position is inputted after it is detected for fixed time, it is judged that the next traveling object stop position is reached.
