Document Type and Number:
Japanese Patent JPH01146502
Kind Code:
A
Abstract:
PURPOSE: To synchronously invert the rotating direction of a driving motor of a take-up mandrel by a method wherein the inversion is performed by two switches, and a first switch is directly excited by an inversion switch, and a second switch is excited after a delay of a certain period of time. CONSTITUTION: When a start switch 13 closes, a driving motor 6 rotates at a position shown in a specified direction which is determined in advance by the polarity of an output voltage at the output part of an electric supply element 10. Then, when a commutator 3 is excited, a relay 9 switchs a switch 1, and both of voltage supply circuits 4 and 5 of the driving motor 6 are connected at the same voltage. A braking is performed until the two voltage supply circuits are short-circuited and stopped. For the resumption of the rotation in the opposite direction, a relay 8 operates after a specified time constant which is obtained by a resistance 11 and a condenser 12, has passed, and a switch 2 is inverted. Thus, the driving motor 6 of a take-up mandrel is connected to the voltage of the opposite polarity, and rotates in the opposite direction.
