Abstract

Two 18V-type rechargeable batteries are attached in series so as to allow a 36V-type tabletop cutting device to be utilized. By utilizing the 18V batteries which are highly prevalent for electric tools, it is possible to use the 36V-type tabletop cutting device as well as to reduce costs for the batteries.

First claim

What is claims is:

1. A tabletop cutting device comprising:
a table on which a cutting material is placed;
a cutting device main body that is operated in a vertically movable manner with respect to the table and includes a circular rotary blade which is rotated by an electric motor; and
a plurality of battery attachment sections for attaching rechargeable batteries such that the batteries are slidably attached to the battery attachment sections, wherein:
the plurality of battery attachment sections are disposed behind the electric motor directly side by side in parallel along a direction perpendicular to a plane of the rotary blade; and
the plurality of battery attachment sections are configured such that the batteries are detachably attached to the plurality of battery attachment sections by sliding each of the batteries along the plane of the rotary blade.

2. The tabletop cutting device according to claim 1 ,
wherein the plurality of the battery attachment sections are disposed offset to a right side with respect to the rotary blade.

3. The tabletop cutting device according to claim 1 , further comprising:
a biasing means for biasing the cutting device main body in an upward direction toward a standby position side,
wherein the cutting device main body is configured to be returned to the standby position side such that weight of the batteries which are attached to the battery attachment section serves as a weight.

4. The tabletop cutting device according to claim 1 , wherein the cutting device main body further comprises:
a main grip part which a user holds when the user performs an up-down movement operation of the cutting device main body; and
a sub grip part which is provided at an end portion of the main grip part on a side opposite to the user, the sub grip part being placed parallel to a top surface of the table and capable of being used for carrying the tabletop cutting device when the cutting device main body is held at a lower moving end,
wherein the plurality of the battery attachment sections are disposed at an end portion of the sub grip part on a side opposite to the main grip part.

5. The tabletop cutting device according to claim 1 , wherein:
the cutting device main body is supported so as to be operated in a vertically tiltable manner with respect to the table; and
the cutting device main body is configured such that a center of gravity of the cutting device main body is displaced to a side opposite to a vertical plane which passes through a tilting fulcrum of the cutting device main body in the course of the vertical tilting of the cutting device main body.

6. The tabletop cutting device according to claim 1 , wherein the plurality of the battery attachment sections are configured to be connected to the cutting device main body via a connection cord.

7. The tabletop cutting device according to claim 6 , wherein the battery attachment sections to which the batteries are attached are utilized as an auxiliary table having the same height as that of the table when the battery attachment section is placed on an installation surface on which the tabletop cutting device is placed.

8. The tabletop cutting device according to claim 1 , wherein:
the plurality of battery attachment sections include a right battery attachment section and a left battery attachment section;
a right end portion of the battery that is attached to the right battery attachment section is located in a plan view on a left side of a base by which the table is supported;
a left end portion of the battery that is attached to the left battery attachment section is located in a plan view on a right side of the rotary blade; and
an attachment surface of each of the battery attachment sections is disposed behind the electric motor and on a front side with respect to each of the batteries to be attached.
