Abstract
Abstract A floor working machine includes a U-turn control unit for causing a self-propelled vehicle body to make a U-turn automatically to adjust the working implement to a work line adjacent a work line treated before the U-turn, a spin turn control unit for causing the self-propelled vehicle body to make a spin turn automatically to adjust the working implement to a work line adjacent a work line treated before the spin turn, and a running control unit for automatically controlling the U-turn control unit and the spin turn control unit in response to input signals for causing the self-propelled vehicle body to make selectively a U-turn under control of the U-turn control unit and a spin turn under control of the spin turn control unit.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
147 words
A floor working machine comprising a self-propelled vehicle body including a working implement (10) for treating a floor surface, characterized by; U-turn control means (55) for causing said self-propelled vehicle body to make a U-turn automatically to adjust said working implement (10) to a work line adjacent a work line treated before said U-turn; spin turn control means (56) for causing said self-propelled vehicle body to make a spin turn automatically to adjust said working implement (10) to a work line adjacent a work line treated before said spin turn; and running control means (53) for automatically controlling said U-turn control means (55) and said spin turn control means (56) in response to input signals for causing said self-propelled vehicle body to make selectively a U-turn under control of said U-turn control means (55) and a spin turn under control of said spin turn control means (56).
Claim 2
Dependent Claim
90 words
A floor working machine as defined in claim 1, characterized in that said running control means (53) includes a semi-automatic control unit (53a), said semi-automatic control unit (53a) being operable, in response to a U-turn command from a control unit (31), to control said U-turn control means (55) for causing said self-propelled vehicle body to make a U-turn, and in response to a spin turn command from said control unit (31), to control said spin turn control means (56) for causing said self-propelled vehicle body to make a spin turn.
Claim 3
Dependent Claim
96 words
A floor working machine as defined in claim 1, characterized in that said running control means (53) includes a full automatic control unit (53b), said full automatic control unit (53b) being operable to control said U-turn control means (55) and said spin turn control means (56) automatically based on a set running program, for causing said self-propelled vehicle body to make U-turns at ends of a working range, and when said running program so requires, for causing said self-propelled vehicle body to make spin turns at predetermined turning positions (X1, XE) and run in opposite directions.
Claim 4
Dependent Claim
53 words
A floor working machine as defined in claim 3, characterized in that said full automatic control unit (53b) is operable to control said spin turn control means (56) for causing said self-propelled vehicle body to make a spin turn in a direction in which a U-turn is made immediately before said spin turn.
Claim 5
Dependent Claim
76 words
A floor working machine as defined in claim 1, characterized in that said self-propelled vehicle body has one dirigible front drive wheel (1) and a pair of right and left non-dirigible, free rotation rear wheels (2), said spin turn control means (56) being operable to cause said self-propelled vehicle body to make a spin turn about a middle position between said right and left rear wheels (2) by steering sideways and driving said front wheel (1).
Claim 6
Dependent Claim
90 words
A floor working machine as defined in claim 5, characterized in that said running control means (53) includes a semi-automatic control unit (53a), said semi-automatic control unit (53a) being operable, in response to a U-turn command from a control unit (31), to control said U-turn control means (55) for causing said self-propelled vehicle body to make a U-turn, and in response to a spin turn command from said control unit (31), to control said spin turn control means (56) for causing said self-propelled vehicle body to make a spin turn.
Claim 7
Dependent Claim
97 words
A floor working machine as defined in claim 6, characterized in that said running control means (53) further includes a full automatic control unit (53b), said full automatic control unit (53b) being operable to control said U-turn control means (55) and said spin turn control means (56) automatically based on a set running program, for causing said self-propelled vehicle body to make U-turns at ends of a working range, and when said running program so requires, for causing said self-propelled vehicle body to make spin turns at predetermined turning positions (X1, XE) and run in opposite directions.
Claim 8
Dependent Claim
53 words
A floor working machine as defined in claim 7, characterized in that said full automatic control unit (53b) is operable to control said spin turn control means (56) for causing said self-propelled vehicle body to make a spin turn in a direction in which a U-turn is made immediately before said spin turn.
Claim 9
Dependent Claim
47 words
A floor working machine as defined in claim 7, characterized in that said running control means (53) having said U-turn control means (55), spin turn control means (56), semi-automatic control unit (53a) and full automatic control unit (53b) is provided in control means (36) comprising a microcomputer.
