The relationship between the height adjustment device and the saw blade holder; the fourth diagram is a schematic diagram of the detector of the embodiment of the invention; the fifth diagram is a schematic diagram of the display module of the embodiment of the invention; The schematic view of the table saw machine shows the state of the raised saw blade; the seventh figure is a schematic view of the table saw machine of the embodiment of the present invention, showing the state of changing the angle of the saw blade; and the eighth figure is another detective of the embodiment of the present invention Schematic diagram of the detector. 20, as shown in the first to third and fifth figures, a table saw machine 10 capable of displaying the height or angle of the saw blade according to an embodiment of the present invention has a base 11, a working platform 21, and a saw The sheet 31, a saw blade holder 41, an angle adjusting device 51, a height adjusting device 61 and a display module 71. Referring to the first figure, the working platform 21 is used to carry a workpiece (not shown in FIG. 6 200821069), and is disposed on the base 11 and has all slots 22 defined therein. Referring to the second and third figures, the saw blade 31 passes through the slot 22 for cutting the workpiece; the blade holder 41 is rotatably disposed in the base 11 at the working platform. Under the 21, the saw blade 31 is engaged to drive the 5 saw blade 31 to rotate; the angle and height adjusting devices 51, 61 each have a rod member 52, 62 and a driving member 54, 64, the two driving members 54, The 64 series is used to respectively drive the two rod members 52, 62 to rotate according to the central axis thereof, and may be in an electric or manual form. In the present embodiment, the hand wheel is taken as an example, and one end of each of the rod members 52, 62 is used. The saw blade holder 41 is coupled to the outside of the base 11 1 , and the hand wheel 54 , 64 is engaged. Referring to the seventh figure, when the user rotates the hand wheel 54 of the angle adjusting device 51 . At this time, the rod member 52 of the angle adjusting device 51 is rotated to yaw the saw blade holder 41, thereby yaw the saw blade 31, and the angle between the saw blade 31 and the working platform 21 is changed to make the saw The piece 31 generates an angular movement amount. Please refer to the sixth figure. When the user turns the hand wheel 64 of the height adjustment device 61, the driver will be driven. Adjusting means 62 rotates the lever 61 opposite the pivot 41 of the seat blade, the movable blade 31 even further, the change of the blade 31 to a height above the working platform 21 so that the height of the saw blade 31 generates a motion amount. Referring to FIG. 5 , the display module 71 has a display 72 , a micro 20 processor 74 , a first detector 76 and a second detector 78 . The first detector 76 has a first sensing member 761 and a first moving member 762. When the angle adjusting device 51 rotates, the first moving member 762 is synchronously rotated to generate a pair of angle adjusting devices. a first angular displacement of the angular displacement of 51, the first angular displacement also corresponding to the angular movement amount of the sheet 31 driven by the angle adjusting device 51 7 200821069 = step, the town = the first angular displacement 'and transmits a representative No. to the microprocessor 74, the microprocessor 74 will generate a first motion signal according to the -first-return, and generate a representative 33 of the angle J to the display 72, and ignore the thousand crying n ❹ ": like = angular displacement, mourning is driven by the second displacement of the angle of the garment 61, and also corresponds to the amount of motion ' ί ί 被 被 该 该 该 该 该 该 该 该 该 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二The two-angle displacement 'and transmits a representative of the = processor 74, the micro-cafe 15: the amount: the second motion signal 'generates - represents the height of the 43th to the display 72, the display 72 will be visualized 'one Less than the user is informed of the high amount of exercise. The item 7^11^2 and the three figures 'the first-moving piece 762 and the second movement of the monetary system m® ring material case are explained, the (four) complex n and the raspberry-inductive piece 781 are respectively opposite ==== == two =, ^ various senses: one of the '' and the two can be the same form, the following two kinds of sensors will be described as an example, for example, please refer to 8 20 200821069 ' is an optical encoder (〇pticai enc〇(jer), the circumference of the torus 762, 782 is equidistantly provided with a plurality of holes, which cooperate with the torus 762', 782, the sensing parts 761, 781 , a light emitter 761a, and a light receiver 761b, respectively located on the two sides of the annular body 762, 782, one of the light emitted by the light 5 emitter 761a' can pass through one of the holes, Projected on the light receiver 761b', or blocked by the body region of the annular body 762, 782' located between adjacent holes, without being projected onto the light receiver 7Mb, on the rod When the 52', 62' rotates, the torus 762, 782 will be synchronously rotated, and the optical receiver 761b, that is, according to whether the light is received, generates 1 〇 representative The annular body 762, 782, the angular displacement of the motion signal; for example, please refer to the eighth figure, the annular body 762,,, 782" is distributed around a plurality of N magnetic poles and S magnetic poles, The sensing member 761", 781" of the annular body 762,, 782" is a Hall element, and when the circular body 762,, 782 is rotated, the detecting range can be detected by The magnetic field generated by the magnetic poles generates a motion signal representing an angular displacement of the toroidal body 762,, 782". In this embodiment, the first correspondence relationship and the second correspondence relationship will be followed. The steps are set as follows: a) Rotate the angle/height adjustment device 51, 61 hand wheel 54, 64 to position the saw blade 31 at an angle/height minimum value, the angle/height minimum value of 20 data system Preset in the microprocessor 74; b) setting an initial point in the microprocessor 74; c) rotating the angle/height adjustment device 51, 6 turns of the hand wheel 54, 64 to position the saw blade 31 At the highest angle/height value, the data of the highest angle/height value is preset in the microprocessor 74; 200821069 d) setting a final point in the microprocessor 74. Thus, the microprocessor 74 can know the first/second motion signal received between the initial point and the final point. The first/one angle of the period, the displacement 'and recalculating the relationship between the difference 5 and the lowest value of the angle/height and the first/two angular displacement can determine the first/second correspondence. In summary, the table saw machine of the present invention causes the saw blade 31 to generate an amount of movement by rotating the angle or height adjusting device 51, 61, and simultaneously rotates the angle or height adjusting device 51, 61. In conjunction with the movement of the moving member 762/782, the sensing members 761, 781 of the moving member 762, 782 can detect the angular displacement of the moving member 762, 782, and transmit a motion signal representing the angular displacement of the moving member 762, 782 to the The microprocessor 74, which in turn responds to the motion signal, generates a display signal representative of the amount of motion of the saw blade 3/1 to the display 72, and visualizes the display signal by the display 72 15 for the user to Know the amount of exercise Accordingly, by using the display 72 = visually informed of the blade 31 and the current location, Yasushi simple ways to take this position the blade 31 of the Rong, convenience and clarity, can effectively improve the conventional drawbacks.
