An apparatus of spreading a fluid on the floor includes four rectangular application rotating bodies partially overlapping each other, and four nozzles supplying the fluid provided in rotation areas of the respective application rotating bodies. The rotation position of the application rotating body is detected by a light shielding plate and a photosensor. A control portion controls each component so that the fluid is applied onto the floor from a tank through the nozzle by a pump when the application rotating body is not directly under the nozzle. As a result, the apparatus of spreading a fluid on the floor capable of optimally controlling the quantity of the fluid to be applied according to the application condition can be provided.

[ What is claimed is:] [1.] A spreading apparatus which is moveable and which spreads a fluid on a surface, comprising:a working unit having a working member which spreads fluid on the surface;a supplier having an outlet in fluid communication with the working unit through which the fluid is applied onto the surface;a speed detector connected to the working unit detecting a moving speed of said working unit, anda controller connected to the supplier for controlling said supplier so as to apply the fluid to the surface through the outlet with the quantity of applied fluid controlled based on a detected moving speed;wherein the controller further comprises a pulse generator generating a pulse, the pulse being used by said controller for controlling the quantity of applied fluid based on a width of the pulse so that fluid is supplied when the pulse is high and fluid is not supplied when the pulse is low,wherein said controller changes the width of the pulse based on the detected moving speed.
