[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable saw machine, and more particularly to a portable saw machine provided with a device for illuminating a cutting edge portion and a cut portion of a saw when in use.

[0002]

[Prior art]

 Conventionally, an apparatus of this type shown in FIGS. 3 to 6 is known (see Japanese Utility Model Publication No. 2-23372). 3 is a side view showing this conventional example, FIG. 4 is a sectional view taken along line IV-IV of FIG. 3, FIG. 5 is a side view showing the same black line alignment state, and FIG. 6 is a side view showing the same maximum incision.

In the figure, 1 is a base that rotatably holds a table 2 on which a piece of wood 3 to be cut is placed, 4 is a hinge portion fixed to the table 2, and 5 a is a fulcrum 6 on the hinge portion 3. A housing having a built-in motor 5a for driving a circular saw 8 which is a pivotally supported saw around the center of the circular saw 8 by means of a spindle portion 9, a fixing flange 10 and a fixing bolt 11. It is mounted rotatably in the direction of rotation C.

The circular saw 8 is covered by a circular saw cover 12 fixed to the motor unit 5 for more than half, and safety covers 14 and 15 for covering the remaining teeth are centered on the fulcrum 13 as indicated by arrow A. The safety covers 14 and 15 are connected to each other by a safety cover holder 16 so as to be swingable in a direction.

Reference numeral 17 is an escape groove provided on the safety cover 14 to prevent contact with the fixing bolt 11, 18 is an escape groove provided on the safety cover 15 to prevent contact with the spindle portion 9, and 19 is an escape groove. The hook 20 is provided at one end of the lever 20, 21 is a fulcrum provided on the cover 12, and 22 is a stopper fixed to the cover 12.

With the above configuration, for example, when attempting to cut wood 3 with black lines, the wood 3 has an operation handle 7 with the left hand, and the lever 20 is moved with the thumb of the right hand or the like as indicated by an arrow C in FIG. By pushing in the direction, the safety cover that is in contact with the hook portion 19 slightly oscillates in the direction of arrow D around the fulcrum 13 and, as shown in FIG. The work of aligning the black lines can be performed by looking through the positions of the cutting edge 8a of the circular saw 8 and the black line (not shown) of the wood 3 without being obstructed by the holder 16.

Further, during normal cutting, as shown in FIG. 6, the hooking portion 19 of the lever 20 enters the escape groove 18 of the safety cover 15 and does not come into contact with the safety cover, and the cutting operation is performed. You can

In this conventional device, since the lever 20 for holding the operation handle 7 and swinging the safety covers 14, 15 is installed on the cover 12 of the circular saw 8, the black line alignment work can be performed efficiently and the safety covers 14, It was something that could be operated safely without manually operating 15.

[0009]

[Problems to be solved by the device]

 However, when using the conventional portable circular saw, for example, when the black line is aligned and the surrounding area is dark, the state of the blade 8a of the circular saw 8 placed on the base 1 and the black line can be seen. If you try to do so, it may be difficult to see, and the work becomes extremely difficult.

In addition, there is a problem that people who have poor eyesight or construction engineers are aging recently and become presbyopia, it is difficult to work in a little dark place, and there is a danger.

The present invention has been made to solve such a problem, and an apparatus for illuminating the cutting edge portion of a saw machine is provided, for example, on a side surface of a hinge portion pivotally supporting a driving means. Therefore, the purpose is to provide a portable saw machine that can perform work properly, easily and safely even in a dark place.

[0012]

[Means for Solving the Problems]

 Therefore, the portable saw machine of the present invention comprises a saw driven by a motor built into the housing, a fixed cover enclosing the saw, and a device capable of illuminating the cutting edge of the saw and the object to be cut. It is a thing.

[0013]

[Action]

 In the above configuration, by providing a device for illuminating the blade edge of the saw and the object to be cut, the state of the blade edge of the saw and the black line can be seen at the time of use, for example, at the time of black line alignment, and it is possible to accurately and safely Easy to work with.

[0014]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 is a side view showing a portable circular saw machine according to an embodiment of the present invention, and FIG. 2 is a front view thereof.

Conventional example The same parts or corresponding parts as in FIGS. 3 to 6 are denoted by the same reference numerals to avoid duplication of description.
