Abstract
Abstract 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.

Claims Analysis
Total Claims: 25
Claim 1
Independent Claim
76 words
A spreading apparatus which spreads a fluid on a surface, comprising: a working unit having a working member which moves along a predetermined path so as to spread the fluid on the surface; a supplier having an outlet through which the fluid is applied onto the surface, said outlet being located over the path of the working member; and a controller which prevents operation of said supplier when the working member is immediately under the outlet.
Claim 2
Dependent Claim
76 words
A spreading apparatus which spreads a fluid on a surface, comprising: a working unit having a working member which moves along a predetermined path so as to spread the fluid on the surface; a supplier having an outlet through which the fluid is applied onto the surface, said outlet being located over the path of the working member; and a controller which prevents operation of said supplier when the working member is immediately under the outlet.
Claim 3
Dependent Claim
17 words
The spreading apparatus as claimed in claim 1, wherein the fluid is wax for finishing the surface.
Claim 4
Dependent Claim
37 words
The spreading apparatus as claimed in claim 1, wherein the working member has a rectangular configuration, and the working member is rotatable around an axis perpendicular to the surface so as to move along a circular path.
Claim 5
Dependent Claim
48 words
The spreading apparatus as claimed in claim 3, wherein a length of the working member is shortened on one side so that a first end of the working member is positioned closer to a rotational center of the working member than a second end of the working member.
Claim 6
Dependent Claim
34 words
The spreading apparatus as claimed in claim 3, wherein said working unit includes at least two working members, and circular paths formed by the two working members are partially overlapped in an overlapped area.
Claim 7
Dependent Claim
27 words
The spreading apparatus as claimed in claim 5, wherein the outlet is located over the overlapped area, and said supplier applies the fluid onto the overlapped area.
Claim 8
Dependent Claim
43 words
The spreading apparatus as claimed in claim 3, wherein said working unit includes at least two working members, one of said working members being driven in a first direction, and the other being driven in a second direction opposite to the first direction.
Claim 9
Dependent Claim
43 words
The spreading apparatus as claimed in claim 3, wherein said working unit includes at least two working members, one of said working members being rotated with a first phase, and the other being rotated with a second phase different from the first phase.
Claim 10
Dependent Claim
36 words
The spreading apparatus as claimed in claim 1, further comprising: a sensor detecting the working member being immediately under the outlet, wherein said controller prevents operation of said supplier based on an output of said sensor.
Claim 11
Dependent Claim
14 words
The spreading apparatus as claimed in claim 9, wherein the sensor is a photosensor.
Claim 12
Dependent Claim
30 words
The spreading apparatus as claimed in claim 9, wherein said working unit includes at least two working members, and the sensor detects each working member being immediately under the outlet.
Claim 13
Dependent Claim
34 words
The spreading apparatus as claimed in claim 1, wherein said controller controls said supplier so as to apply the fluid each time the working member moves along the path a predetermined number of times.
Claim 14
Dependent Claim
34 words
The spreading apparatus as claimed in claim 1, wherein said spreading apparatus is moved along the surface by one of an operator and a moving source provided as a component of said spreading apparatus.
Claim 15
Dependent Claim
69 words
The spreading apparatus as claimed in claim 13, further comprising: a speed detector detecting a moving speed of said spreading apparatus, wherein the working member has a rectangular configuration, and the working member is rotatable around an axis perpendicular to the surface so as to move along a circular path, and said controller controls a rotating speed of the working member based on an output of said speed detector.
Claim 16
Dependent Claim
