Abstract

PURPOSE:To make small the size of encoder and to increase the resolution, by magnetizing the vertical magnetic scale toward moving direction, in the rotary or straight line type encoder in which the detection of angle and position is made digitally and the speed can be detected. CONSTITUTION:The magnetic scale is magnetized on the circumference of the rotary disc plate 1 so that the direction of NS pole is vertical to the rotary direction, and when the rotary disc 1 is turned with the motor 3, digital pulse signal is detected in the coil 5 of the magnetic head 4 formed in channel shape, and it is used for the detection of angullar position or speed. As the disc plate 1, the magnetic disc or the disc coating magnetic material for the circumference magnetized is used, and pulse signal is applied to the channel shape magnetic head clipping the end of the disc the same as the magnetic head 4, and the disc 1 is turned in a given speed. The magnetized pole of scale is along the circumference of the disc 1 and provided with equal distance of interval A and width B.
