The cutting machine 1 includes a base 2 that is brought into contact with a cutting material W, a cutting machine body 3 that is supported so as to be tiltable to the right and left in the cutting direction with respect to the base 2, and a cutting portion and a guide line for aligning the smear line ( An illumination device 5 is provided for brightly illuminating the smear guides 4a and 4b). In this specification, the cutting direction refers to the direction in which the cutting machine 1 moves in the cutting operation and the cutting proceeds. Therefore, the right side in FIGS. 1 and 2 is the cutting direction.
Sumi wire guides 4a and 4b are provided at the front end (right end portion in the figure) of the base 2. In this example, two types are set: a smear line guide 4a for right angle cutting, and a smear line guide 4b for inclined cutting at 45 °. The base 2 is placed on the upper surface of the cutting material W, and the cutting machine 1 is moved while aligning the smear wire guide 4a (or 4b) with a smear wire (not shown) drawn in advance on the upper surface of the cutting material W. By doing so, the cutting edge can be moved along the smear line, whereby the cutting material W can be cut at a right angle (or inclined at 45 °) along the smear line.
Right-angle cutting is performed by making the cutting blade 22 orthogonal to the cutting material W, and inclined cutting is performed at 45 ° by inclining the cutting blade 22 by 45 ° with respect to the cutting material W. The cutting blade 22 is tilted by tilting the cutting machine body 3 with respect to the base 2.

The cutting machine main body 3 is supported so as to be tiltable to the left and right in the cutting direction via tilting support portions F and R provided at two locations on the front portion and the rear portion of the base 2. A tilt support portion F on the front side is provided at the front portion of the base 2 and behind the sumi guides 4a and 4b. This front tilt support portion F includes a tilt base 6 provided so as to rise upward from the upper surface of the base 2. A tilt bracket 8 is provided on the rear surface side of the tilt base 6 via a tilt shaft 7 so as to tilt up and down. As shown in FIG. 1, the tilting position of the tilting bracket 8 with respect to the tilting base 6 is fixed by tightening a fixing nut 8 d to a fixing bolt 8 b provided on the tilting bracket 8. A knob 8c is attached to the fixing nut 8d for convenience of tightening and loosening operation.
Two support edge portions 8a and 8a are provided on the tilting tip side of the tilt bracket 8 so as to protrude rearward in a state of being parallel to each other. A tilting arm portion 29 provided at the front end portion of the cutting machine body 3 is supported between the support edge portions 8a and 8a via the support shaft 9 so as to be tiltable up and down.

A guide bracket 12 is attached to the tilt base 10 via a support shaft 11 so as to be tiltable to the right in the cutting direction. The rear support shaft 11 is arranged coaxially with the front tilt shaft 7. As shown in FIG. 2, the guide bracket 12 is fixed to the blade case 20 by tightening a fixing nut 15 with respect to a fixing bolt 13 attached to the back side of the blade case 20. The fixing nut 15 can be tightened or loosened with respect to the fixing bolt 13 by rotating the lever 14 up and down.
The guide bracket 12 is provided with a long circular arc-shaped guide groove 12a. The guide bracket 12 is fixed to the back surface of the blade case 20 of the cutting machine body 3 through the guide groove 12a.
The front tilt bracket 8 is supported so as to be tiltable up and down about the tilt shaft 7, and the rear guide bracket 12 is supported so as to be tiltable left and right in the cutting direction around the support shaft 9. The cutting machine body 3 can be tilted to the left and right with respect to the cutting direction, whereby the angle of inclination of the cutting blade 22 with respect to the cutting material W can be changed to perform right-angle cutting or inclined cutting.
Further, in a state where the fixing nut 15 is loosened, the cutting machine main body 3 is tilted up and down around the front support shaft 9 to change the amount of protrusion of the cutting blade 22 from the lower surface of the base 2 to thereby change the cutting blade 22. The so-called depth of cut for the cutting material W can be changed.

Next, the cutting machine body 3 includes the blade case 20 and a motor case 21 incorporating a drive motor. A cylindrical gear case portion 20a is provided on the back side of the blade case 20, and the motor case 21 is abutted against the gear case portion 20a so that the blade case 20 and the motor case 21 are connected. The output of the drive motor built in the motor case 21 is decelerated by the gear train built in the gear case portion 20a and outputted as the rotation of the circular cutting blade 22. The cutting blade 22 is located inside the blade case 20.
The cutting edge 22 in the upper half of the cutting blade 22 is covered with a blade case 20, and the lower cutting edge 22 is covered with a safety cover 23 that can be opened and closed. The safety cover 23 is rotated upward during the cutting operation, thereby exposing a range protruding from the lower surface side of the base 2 of the cutting blade 22.

In FIG. 3, the motor case 21 side of the cutting machine main body 3 is shown alone. The motor case 21 is protruded obliquely rearward from the upper surface thereof and has a substantially C-shaped main handle 25 extending to the rear surface, and the front side of the main handle 25 so as to protrude forward from the front surface of the motor case 21. The grip part 26 provided is provided. A main switch 27 for starting and stopping the drive motor is disposed on the inner peripheral side of the main handle 25. A power cord 28 is drawn into the rear part of the main handle 25.
The operator can hold the main handle 25 with one hand, hold the grip portion 26 with the other hand, and move the cutting machine 1 in the cutting direction while firmly supporting it with both hands.
The grip portion 26 incorporates a substrate 5c on which the lighting fixtures 5a and 5b of the lighting device 5 are mounted. The substrate 5c and the two illuminators 5a and 5b are built in the grip portion 26 in a state of being accommodated in the translucent case 5e. In the present embodiment, light emitting diodes (LEDs) are used for the lighting fixtures 5a and 5b. Both of these illuminators 5a and 5b can be turned on and off by turning on and off the illumination switch 5d disposed on the side surface (the front side surface in FIG. 1) near the front base portion of the main handle 25. The driving power of the cutting machine 1 obtained by the power cord 28 is diverted to the power source of the lighting device 5.
As well shown in FIG. 2, of the two illuminators 5a and 5b, the illuminator 5a on the rear side in the figure is directed to the cutting site, and the illuminator 5b on the front side in the figure is the sumiline guides 4a and 4b. Is directed to. In FIG. 1, the cleavage site is indicated by an arrow C.

  According to the cutting machine 1 of 1st Embodiment comprised as mentioned above, when the illumination switch 5d provided in the main handle 25 is turned on, the lighting fixtures 5a and 5b built in the grip part 26 will light. The illuminator 5a is directed to the cutting site C, and the illuminator 5b is directed to the smear line guides 4a and 4b. For this reason, the cutting site C and its periphery and the Sumi-line guides 4a and 4b and their periphery are illuminated simultaneously. For this reason, for example, even when a cutting operation is performed in a dark place, both the cutting site C and the smear line guides 4a and 4b are brightly illuminated, so the operator can visually recognize the position of the cutting edge in the cutting site C relative to the smear line. The cutting operation can be performed easily and accurately while checking, and the right angle cutting (or inclined cutting at 45 °) can be performed while visually checking the position of the smear line guide 4a (or 4b) with respect to the smear line. .

For this reason, in the conventional lighting device that targets only the cutting site C, the worker who performs the cutting work based on the smear guide has caused a reduction in work efficiency. However, according to the cutting machine 1 illustrated above, Since the smear guides 4a and 4b and their surroundings are brightly illuminated, the cutting operation can be performed efficiently.
In addition, according to the lighting fixture 5b, a light is irradiated to the sumi guides 4a and 4b from the side surface of the grip part 26 diagonally downward. The irradiation path is set such that the position of the lighting tool 5b or the shape and position of the front side tilting support part 6 is set so as to pass above the front side tilting support part 6, so that the irradiation tool 5b emits light. The light is prevented from being blocked by the front tilt support portion F.
In addition, since the lighting fixtures 5a and 5b of the illustrated lighting device 5 are arranged in the grip portion 26, wiring is easy, and wiring is sufficient only on the motor case 21 side. Since it is not necessary to carry out wiring over, convenience at the time of the assembly | attachment of the said cutting machine 1 or a maintenance can be aimed at.
Various modifications can be made to the first embodiment described above. For example, the illumination tool 5a that illuminates the cutting site C may be omitted. Moreover, it is good also as a structure which can arrange | position two lighting switches and can turn on and off the lighting fixtures 5a and 5b independently.
Moreover, although the structure which diverts the power supply for the said cutting machine drive was illustrated as a power supply of the illuminating device 5, it is good also considering a dry cell etc. as a power supply separately, for example.

Next, a second embodiment will be described with reference to FIGS. This second embodiment corresponds to an embodiment of the fourth or fifth invention. In the first embodiment described above, the configuration in which the lighting fixtures 5a and 5b of the lighting device 5 are disposed in the grip portion 26 provided in the front portion of the motor case 21 is exemplified. However, the cutting machine according to the second embodiment described below. 30 is characterized in that the lighting fixture 33a of the lighting device 33 is attached using the tilting shaft 32 of the front tilting support portion F2 that tilts and supports the cutting machine body 31.
Hereinafter, members and configurations that do not need to be changed as compared with the first embodiment will be described using the same reference numerals as appropriate, and description thereof will be omitted.
At the front end of the base 2, as in the first embodiment, a right angle cutting smear wire guide 4a and a 45 ° tilt cutting smear wire guide 4b are provided.

6 and 7 show details of the front tilt support portion F2 in the second embodiment. The front tilt support portion F2 has support block portions 35 and 36 provided on the upper surface of the base 2 at a predetermined interval in the cutting direction (left-right direction in FIG. 6). A tilting shaft 32 is attached between the support blocks 35 and 36 so as to be bridged. A tilting block 34 is supported on the upper surface of the base 2 via the tilting shaft 32 so as to be tiltable left and right in the cutting direction. The tilt block 34 is provided with support edge portions 34 a and 34 a parallel to each other, and the tilt arm portion 31 a of the cutting machine main body 31 is vertically moved via a support shaft 37 between the support edge portions 34 a and 34 a. It is supported so that it can tilt.
With the above configuration, the cutting machine main body 31 can be tilted to the left and right in the cutting direction about the tilting shaft 32, thereby making a right angle cut or a tilt cut. Moreover, the cutting machine main body 31 can be tilted up and down around the support shaft 37, whereby the cutting depth of the cutting blade 22 can be changed.

The rear end side of the tilting shaft 32 is stepped as shown in FIG. 6, and the stepped surface is abutted against the rear support block 36, and the front end side of the tilting shaft 32 is fixed screw. The tilting shaft 32 is fixed so as not to be separated from both the support blocks 35 and 36 by being fixed to the front support block 35 by 35a.
Further, a tilt fixed base 38 is provided on the upper surface of the base 2 and in front of the tilt block 34 so as to rise upward. The tilting position of the tilting block 34 with respect to the tilting fixing base 38 is fixed between the tilting fixing base 38 and the tilting block 34 by tightening a nut to a fixing bolt provided on the tilting block 34. The tilt position of the main body 31 is fixed. In FIGS. 5 and 7, only the knob 38b attached to the fixing nut is visible.
Further, as shown in FIG. 7, a guide groove 38a having an arc shape is formed in the tilt fixing base 38, and the fixing bolt is inserted into the guide groove 38a. An angle scale 38c is attached to the guide groove 38a, and the angle of inclination of the cutting machine main body 31 with respect to the base 2 can be accurately confirmed by the angle scale 38c.

A hollow shaft is used as the tilt shaft 32. On the inner peripheral side of the tip end of the tilting shaft 32, one lighting fixture 33a and a substrate 33c on which this is mounted are housed. As in the first embodiment, a light emitting diode (LED) is used for the illumination tool 33a. In addition, the front of the illumination tool 33a is covered with a translucent cover 33b. The cover 33b is fitted to the inner peripheral surface of the tilting shaft 32 with a constant pressing force and is fixed by an adhesive, so that it cannot be easily removed by vibration or the like.
As shown in the drawing, the tip of the tilting shaft 32 and the illuminating device 33a are located at a position very close to the above-mentioned smear line guides 4a and 4b.

The electrical wiring 33d for supplying power to the substrate 33c is drawn into the blade case 39 through the rear end opening of the tilt shaft 32. The electrical wiring 33d is wired using a space between the back surface of the blade case 39 and a shielding plate 39a attached along the back surface. Within this space, the electrical wiring 33d is routed in a state having moderate slack. This slack is shown in FIG. 4 by being wired along a path that gently snakes in an S-shape. Due to this slack, when the cutting machine body 31 is tilted to the left and right in the cutting direction with respect to the base 2, or when the cutting machine body 31 is tilted up and down, the electric wiring 33d is strongly pulled so as not to be disconnected.
As shown in FIG. 5, the electrical wiring 33d is connected to the electrical wiring on the motor case 31b side in the vicinity of the joint J between the gear case portion 39b of the blade case 39 and the motor case 31b. And it is routed in the motor case 31b from the gear case portion 39b.

Also, as shown in FIG. 5, a bevel portion 39c that opens downward is formed on the back side of the blade case 39 and on the front side of the gear case portion 39b, and the illumination tool 39d is also formed inside the bevel portion 39c. Is arranged. The lighting tool 39d is directed to the cutting site C. Unlike the lighting device 33a, a normal miniature light bulb is used for the lighting device 39d. Similarly to the electrical wiring 33d, the electrical wiring 39e of the lighting tool 39d is connected to the electrical wiring on the motor case 31b side by a connector.
Further, as in the first embodiment, an illumination switch is disposed on the front side surface of the main handle 25. This illumination switch is connected to the electrical wirings 33d and 39e. Therefore, the illumination tool 33a can be turned on / off by turning on / off the illumination switch.

According to the cutting machine 30 of 2nd Embodiment comprised as mentioned above, when the illumination switch provided in the main handle 25 is turned ON, the lighting fixture 33a will light. The illuminating device 33a is disposed on the inner peripheral side of the tilt shaft 32 of the tilt support portion F2 on the front side, and is located at a position very close to the smear line guides 4a and 4b. For this reason, when the illumination switch is turned on and the lighting fixture 33a is turned on, the smear line guides 4a and 4b are illuminated brightly. Therefore, when the cutting work is performed on the basis of the smear line drawn in advance on the cutting material W, and when the cutting work is performed in a dark place or the like, the smear line guides 4a and 4b and the periphery thereof are brightly illuminated. Cutting work can be performed efficiently.
Further, when the illumination switch is turned on, the illumination tool 39d is turned on together with the illumination tool 33a, so that the cutting site C is brightly illuminated. Therefore, the work efficiency when performing the cutting work while confirming the cutting site C with the eyes is increased. be able to.

Further, since the lighting fixture 33a is built in the tilting shaft 32 of the front side tilting support portion F2, the position does not change even if the cutting machine body 31 is tilted to the left and right in the cutting direction. Therefore, the electric wiring 33d from the lighting fixture 33a. The lighting device 33 can be improved in durability without being twisted. Further, the slack of the electric wiring 33d can be suppressed to the minimum in order to allow the cutting machine body 31 to tilt, and therefore the wiring 33d can be easily routed.
Various modifications can be made to the second embodiment. For example, a light emitting diode may also be used for the illumination tool 39d that illuminates the cut portion C. On the other hand, the lighting tool 39d for the cutting part C may be omitted, and only the smear line guides 4a and 4b and the periphery thereof may be illuminated brightly.
Moreover, although the structure which uses a light emitting diode as the lighting fixture 33a was illustrated, it may replace with this and a normal miniature light bulb may be used.
Moreover, although the structure which diverts the power supply for the said cutting machine drive was illustrated as a power supply of the illuminating device 33, it is good also as a power supply using a dry cell etc. separately, for example.

Next, an embodiment (third embodiment) of the sixth invention will be described. The third embodiment does not include a dedicated lighting tool for illuminating the smear line guides 4a and 4b, and uses the light of the illuminating tool for illuminating the cutting site C to brightly illuminate the smear line guides 4a and 4b. It has a configuration. The same members and configurations as those of the second embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The cutting machine according to the third embodiment includes the illumination tool 39d according to the second embodiment. This lighting tool 39d is connected to the drive power supply circuit of the cutting machine via an electrical wiring 39e. Further, the illumination tool 39d can be turned on by turning on the illumination switch 5d (see FIG. 3) provided on the main handle 25. When the lighting tool 39d is turned on, the cutting site C is brightly illuminated, so that the operator can clearly see the cutting site C even in a dark place, thereby enabling efficient cutting work. About these points, it is the same as that of the effect by the lighting fixture 39d of 2nd Embodiment.
Thus, although the cutting part C is brightly illuminated by the illumination tool 39d, the front side tilting support portion composed of the tilting block 34, the support blocks 35, 36, etc. is provided between the cutting part C and the smear line guides 4a, 4b. Since F3 is located, conventionally, the light of the illuminating device 39d does not reach the smear line guides 4a and 4b. Therefore, in a dark place, the side of the smear line guides 4a and 4b is shaded and difficult to see. It becomes. However, according to the illuminating device 40 of 3rd Embodiment demonstrated below, the light line guides 4a and 4b can be illuminated brightly using the light of the lighting fixture 39d for the cutting | disconnection site | parts C. FIG.

As shown in FIG. 8, a hollow shaft is used as the tilt shaft 41 in the front tilt support portion F <b> 3 for tilting and supporting the cutting machine main body (not shown) left and right in the cutting direction. This is the same as in the second embodiment. A transparent resin sleeve 43 having a light diffusion lens portion 43a at the front end is fitted on the inner peripheral side of the tilt shaft 41. The condensing lens 42 is fixed to the rear end portion of the sleeve 43 so as not to drop off. In the case of the third embodiment, the illumination device 40 is configured by the illumination tool 39d, the lens 42, the sleeve 43, and the like.
According to the illumination device 40, the light of the illumination tool 39d that illuminates the cutting site C and its periphery on the cutting site C side (left side in FIG. 8) with respect to the front tilt support portion F3 is condensed on the lens 42. After that, the lens portion 43a is irradiated through the inside of the sleeve 43, and then is diffused by the lens portion 43a and irradiated to the front side, that is, the front tilt support portion F3 to the side opposite to the cutting portion C. The guide portions 4a and 4b are brightly illuminated.
As described above, since the light guides 4a and 4b are brightly illuminated by using the light of the illumination tool 39d for the cutting part C, the worker performs a cutting operation while visually checking the light guides 4a and 4b in a dark place. Can be performed efficiently. Moreover, since the cutting part C is also brightly illuminated by the illumination tool 39d, it is possible to efficiently perform the cutting operation while visually checking the cutting part C.

Next, an embodiment (fourth embodiment) of the seventh invention will be described with reference to FIG. Similarly to the third embodiment, this fourth embodiment also does not include a dedicated illumination tool for illuminating the smear line guides 4a and 4b, and diverts the light of the illumination tool 39d for illuminating the cutting site C. The line guides 4a and 4b are brightly illuminated. Since these configurations are the same as those of the third embodiment, description thereof will be omitted.
A hollow shaft is also used as the tilt shaft 51 of the front tilt support portion F4 in the cutting machine of the fourth embodiment. In the case of the fourth embodiment, unlike the third embodiment, other members such as the sleeve 43 and the lens 42 are not incorporated on the inner peripheral side of the tilting shaft 51 and are left in a hollow state. . In the case of the fourth embodiment, the illumination device 50 is configured by the tilt shaft 51, the illumination tool 39d, the illumination switch 5d, and the like.
According to the illuminating device 50 configured as described above, the cut portion C is brightly illuminated by the illumination tool 39d, and the light is irradiated to the inner peripheral side of the tilting shaft 51, which passes through the inner peripheral side of the tilting shaft 51. Since it is irradiated to the opposite side of the cutting site C side, that is, the sum line guides 4a and 4b, the sum line guides 4a and 4b are brightly illuminated by the illumination tool 39d without being shielded by the tilting support portion F4 even in a dark place. Thus, an efficient cutting operation can be performed with reference to the smear guides 4a and 4b.
