Filed: 1988-12-27
Abstract: PURPOSE:To control the rotation speed of a rotary brush corresponding tot the types of floors by detecting the reflection of light, that is emitted to the floor, by light receiving elements. CONSTITUTION:An oscillation circuit 5 drives a light emitting element 6, and the light emitted from the light emitting element 6 is reflected by a floor 7 and detected by light receiving elements 8 and 9. The outputs from the light receiving elements 8 and 9 are input to a differential amplifier 10, and further transmitted to the gate of a dual directional thyristor 12 through a level detector 11. By this constitution, mal-functioning due to difference in color can be prevented because the light reflected by the floor is detected by two light receiving elements 8 and 9, the difference between them is amplified, and only the change quantity of the light is detected, so that the same signal is generated even when the floor changes in color. For the circuit action, when the output from the differential amplifier 10 exceeds the reference voltage 20, the dual directional thyristor 12 is turned on so as to supply power to a motor 13. That is, a rotary brush is controlled in such a manner that when changes in the roughness of the floor become larger than a certain value, the rotary brush is turned on, and when it is smaller, the rotary brush turned off.
