Abstract

A driving device includes: a cylindrical-shape magazine configured to house fasteners connected in a roll form; an injecting portion configured to receive the fastener fed from the magazine; a striking portion configured to be movable in a first direction in which the fastener fed to the injecting portion is allowed to be struck and movable in a second direction opposite to the first direction; a first bias portion configured to move the striking portion in the first direction; an electrical motor moving the striking portion in the second direction; a housing configured to support the striking portion and the electrical motor; and a handle configured to protrude from the housing in a direction crossing a moving direction of the striking portion. The electrical motor has a rotary shaft, and the rotary shaft extends in a direction crossing a plan orthogonal to the moving direction of the striking portion.

First claim

The invention claimed is:

1. A driving device comprising:
a magazine configured to house a plurality of fasteners;
an injecting portion configured to receive one of the fasteners fed from the magazine;
a striking portion configured to be movable in a first direction to strike the one of the fasteners fed to the injecting portion and movable in a second direction that is opposite to the first direction;
a cylinder configured to guide movement of the striking portion;
a pressure chamber configured to be filled with a compressed gas to move the striking portion in the first direction;
an electrical motor;
a wheel coupled with the striking portion and configured to be rotated by the electrical motor to move the striking portion in the second direction;
a housing configured to support the striking portion and the electrical motor; and
a handle configured to protrude from the housing in a third direction crossing the first and second directions,
wherein the electrical motor has a rotary shaft,
wherein the rotary shaft extends in parallel to the first and second directions, and is arranged to be adjacent to the cylinder in a fourth direction crossing the first to third directions,
wherein the rotary shaft is arranged between a center axis of the cylinder and the handle in the third direction,
wherein a rotary axis of the wheel extends in a fifth direction that is orthogonal to the first and second directions, and
wherein the cylinder and the wheel are arranged to overlap in the first and second directions.

2. The driving device according to claim 1 ,

4. The driving device according to claim 1 further comprising:
a control portion configured to control the electrical motor; and
a feeding portion configured to be movable to feed the one of the fasteners housed in the magazine to the injecting portion,
wherein the feeding portion is controlled by the control portion.

5. The driving device according to claim 4 ,
wherein the feeding portion is moved by the electrical motor.

6. The driving device according to claim 1 ,
wherein the electrical motor is a brushless motor.

7. The driving device according to claim 1 ,
wherein an arrangement region of the electrical motor and an arrangement region of the magazine partially overlap each other in a sixth direction crossing the first and second directions inside a second virtual plane crossing a direction of protrusion of the handle from the housing.

8. A driving device comprising:
a cylindrical-shape magazine configured to house a plurality of fasteners connected in a roll form;
an injecting portion configured to receive one of the fasteners fed from the cylindrical-shape magazine;
a striking portion configured to be movable in a first direction in which to strike the one of the fasteners fed to the injecting portion and movable in a second direction that is opposite to the first direction;
a biasing portion configured to move the striking portion in the first direction;
