Title:
DRIVING DEVICE FOR AIR COURSE-VARYING BOARD
Document Type and Number:
Japanese Patent JPH07260350
Kind Code:
A
Abstract:

PURPOSE: To control air course-varying boards with simple formation, and to prevent a load from being applied to the control of other functions.

CONSTITUTION: Since a cam surface 28a deciding the range of reciprocating motion of air course-varying boards 20, 21 is provided on a cam 28 operating together with the air course-varying boards 20, 21, timing of each terminal point of the reciprocating motion by the air course-varying boards 20, 21 can be recognized by detecting the cam surface by means of a limit switch 29, and a load for switching the polarity of a voltage or an electric current to be applied to a solenoid operated actuator 26, i.e., for controlling the air course- varying boards, is not applied to others. Therefore, the whole of a drying box can be controlled by a simple and inexpensive control circuit.
