Abstract

A cutting device main body with a saw blade in a tabletop cutting device, supported so as to be swingable in an up-to-down direction with respect to a table on which material to be cut is placed, aims to improve operability for attaching and detaching the battery. A sliding direction for attaching and detaching the battery is set to be a tilting direction angled with respect to an up-to-down moving direction of the cutting device main body in a surface direction of a cutting blade. Because of this configuration, all of an operation force for attaching and detaching the battery is not applied to the up-to-down moving direction of the cutting device main body. As a result, the cutting main body is not moved in an easy manner and operability for attaching and detaching the battery is improved.

First claim

What is claimed is:

1. A cutting device for tabletop or stationary use, comprising:
a table configured to receive a material to be cut;
a cutting device main body moveably attached to the table, the cutting device main body including a cutting blade having side surfaces;
a motor configured to drive the cutting blade and having a motor axis; and
a cordless battery attachment portion that includes a battery attachment base that (i) receives and engages a battery and (ii) is directly mounted on an upper side of the cutting device main body with regard to the table; wherein:
the battery attachment portion and the battery are configured such that the battery is attached to the battery attachment portion in a sliding direction;
the battery is on a same side of the cutting blade as the motor and above the motor with regard to the table; and
the sliding direction (i) is not parallel to planes that include one of the side surfaces, (ii) is tilted downward with respect to the planes and toward the motor from the cutting blade such that an upper end of the battery attachment base is toward the planes and a lower end of the battery attachment base is toward the motor and (iii) intersects the motor axis.

2. The cutting device according to claim 1 , wherein a thickness direction of the battery is parallel to the motor axis or within an angle range between a parallel direction and a vertical direction.

3. The cutting device according to claim 1 , further comprising a second battery structured to be attached to the cutting device main body in the sliding direction, the batteries being arranged side by side in a front-to-rear direction.

4. The cutting device according to claim 1 , wherein the motor axis is perpendicular to the sliding direction.

5. The cutting device according to claim 1 , wherein a portion of the battery closest to the cutting direction is spaced farther from the table than a portion of the battery farthest from the cutting direction.

6. The cutting device according to claim 1 , wherein a portion of the battery is positioned farther from the table than a motor housing.

7. The cutting device according to claim 1 , wherein the battery attached to the battery attachment portion is above a carrying handle.

8. A cutting device, comprising:
a supporting base portion;
a cutting device main body structured to pivot about a pivot axis with regard to the supporting base portion;
a cordless battery attachment portion that is directly mounted on an upper side of the cutting device main body and has a primary battery support surface that is (i) configured to receive and engage a battery and (ii) is not parallel to a plane perpendicular to the pivot axis;
a cutting blade configured to cut a workpiece in a cutting direction perpendicular to the pivot axis and having side surfaces; and
a motor configured to rotate the cutting blade about a blade rotation axis parallel to the pivot axis, the motor having a motor axis, wherein:
the battery attachment portion is structured to receive a battery slid along the primary battery support surface;
the battery is on a same side of the cutting blade as the motor; and
a sliding direction of the battery (i) is not parallel to the plane, (ii) is tilted downwards in a direction perpendicular to the cutting direction and toward the motor from the cutting blade such that an upper end of the primary battery support surface is toward the cutting blade and a lower end of the primary battery support surface is toward the motor, and (iii) intersects the motor axis.

9. The cutting device according to claim 8 , wherein the motor axis is perpendicular to the primary battery supporting surface.

10. The cutting device according to claim 8 , wherein the battery attachment portion is positioned to pivot about the pivot axis when the cutting device main body pivots about the pivot axis.

11. The cutting device according to claim 8 , wherein the primary battery supporting surface is:
parallel to the pivot axis, or
tilted so as to be between parallel to the pivot axis and perpendicular to the pivot axis.

12. The cutting device according to claim 8 , wherein the battery attachment portion is nearer the pivot axis than the motor.
