Abstract

A datum plane setting device capable of generating two or three reference planes is provided. The device includes a motor 6, rotary bodies 3 (3x, 3y, and 3z) which rotate in accordance with rotary driving of said motor via a direct drive and belt drive, rotary heads 8 formed on the tip end portions of said rotary bodies 3, laser emitting portions 9 which are accommodated inside said rotary heads 8 and rotate with said rotary heads 8 as one body. A power source supplies current for the motor 6 and laser emitting portions 9. A casing 2 accommodates the motor 6, rotary bodies 3, power source 5, supporting members for horizontally supporting said casing, and a level 27 for confirming a level of said casing. The laser emitting portions 9 are constructed so that current is supplied from the power source 5 via current-supplying brushes 1501 which contact guiding paths provided around the rotary bodies 3.

Claims

1. A datum plane setting device comprising:

a motor, rotary bodies which rotate in accordance with rotary driving of said motor, rotary head portions formed on the tip end portions of said rotary bodies, laser emitting portions which are accommodated inside said rotary head portions and rotate with said rotary heads as one body, a power source portion which supplies current for the motor and laser emitting portions, a casing which accommodates at least the motor, rotary bodies, the power source portion, supporting members of said casing horizontally supporting thereof, and a level confirming a horizontal level of said casing, wherein

the laser emitting portions are composed so that current is supplied from the power source portion via current-supplying brushes which contact guiding paths provided to surround the rotary bodies,

wherein said rotary bodies include a first rotary body fixed to a rotary axis of the motor and at least one or more second rotary bodies which rotate with the first rotary body simultaneously via a belt which is wound around a pulley formed on the rotary axis portion.

2. A datum plane setting device comprising:

a motor, rotary bodies which rotate in accordance with rotary driving of said motor, rotary head portions formed on the tip end portions of said rotary bodies, laser emitting portions which are accommodated inside said rotary head portions and rotate with said rotary heads as one body, a power source portion which supplies current for the motor and laser emitting portions, a casing which accommodates at least the motor, rotary bodies, the power source portion, supporting members of said casing horizontally supporting thereof, and a level confirming a horizontal level of said casing, wherein

the laser emitting portions are composed so that current is supplied from the power source portion via current-supplying brushes which contact guiding paths provided to surround the rotary bodies,

with respect to the rotary bodies, at least two rotary bodies or more are disposed and such a plurality of rotary bodies are rotatable simultaneously, and further including

a positional adjusting unit for allowing said supporting members to be adjustably slidable in X axis and Y axis directions relative to said casing.

3. A datum plane setting device comprising:

a motor, rotary bodies which rotate in accordance with rotary driving of said motor, rotary head portions formed on the tip end portions of said rotary bodies, laser emitting portions which are accommodated inside said rotary head portions and rotate with said rotary heads as one body, a power source portion which supplies current for the motor and laser emitting portions, a casing which accommodates at least the motor, rotary bodies, the power source portion, supporting members of said casing horizontally supporting thereof, and a level confirming a horizontal level of said casing, wherein

the laser emitting portions are composed so that current is supplied from the power source portion via current-supplying brushes which contact guiding paths provided to surround the rotary bodies,

with respect to the rotary bodies, at least two rotary bodies or more are disposed and such a plurality of rotary bodies are rotatable simultaneously,

wherein said supporting members are arranged so as to support the casing, in total, at four points forming a square against the device setting surface, wherein one point of said supporting members is a fixing supporting member and another point on the diagonal line is a buffering supporting member which applies force upward by an elastic member, and for two supporting members existing on the remainder of the diagonal line, a leveling adjustment screw for a horizontal leveling adjustment is provided, respectively.

4. A datum plane setting device comprising:

a motor, rotary bodies which rotate in accordance with rotary driving of said motor, rotary head portions formed on the tip end portions of said rotary bodies, laser emitting portions which are accommodated inside said rotary head portions and rotate with said rotary heads as one body, a power source portion which supplies current for the motor and laser emitting portions, a casing which accommodates at least the motor, rotary bodies, the power source portion, supporting members of said casing horizontally supporting thereof, and a level confirming a horizontal level of said casing, wherein

the laser emitting portions are composed so that current is supplied from the power source portion via current-supplying brushes which contact guiding paths provided to surround the rotary bodies,

with respect to the rotary bodies, at least two rotary bodies or more are disposed and such a plurality of rotary bodies are rotatable simultaneously,

wherein the rotary bodies are arranged to be freely attached and removed.

5. A datum plane setting device comprising:

a motor, rotary bodies which rotate in accordance with rotary driving of said motor, rotary head portions formed on the tip end portions of said rotary bodies, laser emitting portions which are accommodated inside said rotary head portions and rotate with said rotary heads as one body, a power source portion which supplies current for the motor and laser emitting portions, a casing which accommodates at least the motor, rotary bodies, the power source portion, supporting members of said casing horizontally supporting thereof, and a level confirming a horizontal level of said casing, wherein

the laser emitting portions are composed so that current is supplied from the power source portion via current-supplying brushes which contact guiding paths provided to surround the rotary bodies,

with respect to the rotary bodies, at least two rotary bodies or more are disposed and such a plurality of rotary bodies are rotatable simultaneously, and further including

a positional adjustment unit for adjustably and slidably moving said supporting members relative to the casing such that said laser emitting portions of said rotating head portions are adjustably and slidably movable with respect to said casing.
