When the exciting coil 6 is energized, the movable core 4 is attracted by the fixed iron core 3 and moves toward the lower side of the figure. With this movement, the step portion 4b abuts against the contact plate 8a and moves toward the lower side of the figure. After the contact plate 8a is lowered, the movable contact 8 will leave the fixed contact 7, and the energization of the exciting coil 6 will be cut off. Thus, the movable core 4 is raised by the restoring action of the spacer 2, and the movable contact 8 is brought into contact with the fixed contact 7' to energize the exciting coil 6 again. By repeating the above actions, the soundboard 9 will vibrate up and down to generate a warning sound. In order to emit a smooth warning sound, the size management of the air gap G, and the gap between the step portion 4b and the contact plate 8a (hereinafter referred to simply as the contact gap) is extremely important. It is known that the adjustment screw for the purpose of adjusting the contact gap by an artificial method is -4- (2) 1302295 (for example, refer to Patent Document 2).

The inspector performs performance verification, and the inspector connects the test power source to the flat type electric type sound alarm machine 1, and listens to the sound and adjusts it with an adjustment screw (patent document 2, unsigned screw in Fig. 6). Use adjustments to ensure a specific tone and volume. However, the inspector must decide to rotate the adjustment screw to the right or to the left in response to the sound he hears, so the less experienced inspector needs some time to make adjustments. That is, a skilled inspector is required. In addition, the accuracy of the components and the accuracy of the combination are poor, and the error of the joint gap is large, and even the skilled inspector needs more time and steps to adjust. Further, as shown in Fig. 6 of Patent Document 2, after the combination, the portion of the contact gap is inside the flat type electric type radio 1 , so visual inspection is difficult. Therefore, an inspector who needs less experience can easily adjust the contact gap of the combined flat type electric police machine and confirm the performance in a short time -5 - 1302295 (3).

Until the non-conduction state, when the conduction state confirmation step confirms that it is in the non-conduction state, the non-conduction state setting step of the rotation adjustment screw is stopped; the zero point adjustment (5) 1302295 step for moving the fixed contact to the zero position; After the zero point adjustment step, the adjustment contact screw is used to move the fixed contact so that the movable contact lever and the kickback member become the contact gap securing step of the predetermined contact gap; therefore, the contact gap of the flat type alarm can be adjusted. That is, the series of steps consisting of the conduction state confirming step, the zero point adjusting step, and the joint gap securing step does not require a proficiency step. Therefore, with the first application of the patent scope, the inspectors with lesser experience can easily implement the adjustment of the contact gap. • The contact gap adjustment tool of the invention of claim 2 is: a contact state detecting means for detecting whether the tool body and the movable contact and the fixed contact are electrically connected; and the fixed contact a target distance moving means for moving the target distance toward the side of the spacer or the fixed core; the second step of the 'monitoring contact state detecting means simultaneously rotating the adjusting screw, detecting that the movable contact and the fixed contact are changed from the conductive state to the non-conductive state, or From the non-conducting state to the switching state of the conduction state, the target distance movement is used to move the movable contact rod to the fixed iron core side only by the target distance, so that the contact gap of the flat type alarm can be adjusted. The above operations do not require proficiency. Therefore, the use of the second item of the patent application can provide a fixture that can be easily adjusted by an inspector with less experience. According to the third aspect of the invention, the positioning of the flat type alarm device can be achieved by arranging the outer edge of the flat type alarm device in the support portion of the tool body, so that the work can be made more efficient. In addition, the flat type alarm side does not need to be equipped with a set protrusion, etc., and the flat type alarm can maintain the general shape of -8 - (6) 1302295. Therefore, using the third item of the patent application scope can prevent the cost of the flat type alarm device from rising, and the efficiency of the adjustment work can be realized. [Embodiment] A preferred embodiment of the present invention will be described with reference to the drawings. In addition, the direction of the 'picture' is the same as the direction of the symbol. In addition, the instructions • All the top screws are right-handed screws. 1 is a structural explanatory view of a flat type alarm device of an object to be adjusted according to the present invention, and a flat type housing η of the flat type alarm device 10 houses a fixed iron core 1 2 and a magnetizing wire 圏 13 , and an adjusting screw 1 4, extending into the housing 1 1 'with the adjusting screw 14 4 supporting the fixed contact 17 via the fixed contact rod 16 with the screw receiving seat 15 , the fixed contact 17 is connected with the movable contact 1 8 In a relative arrangement, the movable contact 1 8 is supported by the movable contact lever 19, and the contact is pushed in the closing direction, and the flange 21 of the casing n is placed with the spacer 22 on the spacer 22 Further, a cover 24 is placed, and the cover 25 of the cover 24 is wound around the flange 21, whereby the center of the rim portion 26' is formed with the movable iron core 27 in the center of the spacer 2' The movable core 2 7 has a recoil member 2 8 for recoiling the movable contact lever 19, and has a sounding plate 29. The kick member 28 has a first insulating plate 31. 3 2 is a bracket used when the flat type alarm 10 is mounted on a vehicle body or the like, and the 3 3 is disposed in a mounting hole of the bracket 32. Further, 3 4 (... indicates that the plural 'the same applies hereinafter') is formed in the hole of the cover 24, the 35-type lock nut, and the 3 6 and 3 7 are connected to the -9- (7) of the exciting coil 13 1302295 Terminals and wiring harnesses, 3 8 and 3 9 are connected to the terminals and wiring harness of the fixed contact rod 16 , and 4 1 is used to connect the excitation coil 13 and the movable contact rod 1 9 harness, 4 2 The board '4 3 is the third insulation board. For convenience of explanation, the flat type casing 11 and the cover 24 and the bracket 32 are shown by two dotted lines. Further, the screw receiving base 15, the first insulating plate 31, the second insulating plate 42, and the third insulating plate 43 are formed of an insulating material such as resin or rubber. However, in order to ensure the specificity of the flat type alarm device 10 The tone, the contact gap d 1 of the movable contact lever 19 and the kickback member 2 8 must be adjusted to the target contact gap, for example, adjusted to 0 · 15 mm. The adjustment of the contact gap d 1 is easy to carry out by using the contact gap adjusting tool described below. 2 is a perspective view of a contact gap adjusting tool of the flat type alarm device of the present invention, and a contact gap adjusting tool 50 of the flat type alarm device has: a detecting flat type alarm device (Fig. 1 is a symbol 1) 〇) The tool body 51 and the movable contact (symbol 1 in Fig. 1) and the fixed contact (Fig. 1 is the symbol #1 7) are in the state of contact state detection in the electrically conductive state (Fig. 3) Symbol 73); and the target distance moving means for moving the target distance to the fixed contact (symbol 17 in Fig. 1) toward the side of the spacer (symbol 23 in Fig. 1) or the side of the fixed core (symbol 12 in Fig. 1) 5 2. The above-described components are described in detail below. The configuration of the tool body 5 1 is such that the third plate 5 5 is disposed between the first plate 5 3 and the second plate 5 4 , and the plates 5 3 , 5 4 , 5 5 The bonding is performed by bolts or pins 56. The first plate 53 has a pass--10-(8) 1302295 孑L 5 7 for the target distance moving means 52 to pass, and a scale mark having a reference mark 58 as an angular scale of the indexer formed on the through hole 57. Disk 59. The second plate 54 has a support portion 61 that abuts against the outer edge crevice portion (symbol 26 in Fig. 1), and a guide portion 63 that is provided with a convex portion 62 that passes through the mounting hole (symbol 33 in Fig. 1). . The third plate 55 is formed of a rectangular or square block shape for determining the interval between the first plate 5 3 and the second plate 5 4 . The target distance moving means 52 is composed of a shaft portion 65 having a screw rotating portion 64, a scale bar 66 disposed on the shaft portion 65, and a knob portion 67. The screw rotating portion 64 is fitted to the shape and size of the adjusting screw (the symbol 1 in Fig. 1). Further, in the present example, since the tool body 51 is composed of three plates 5 3, 54, and 55, when the portion is damaged, it is only necessary to replace the plates 53, 54, or 55. Further, the third plate 55 may be replaced by a spacer or the like. Since the tool body 51 can be manufactured by cutting a metal block or by a press forming of a metal plate, the configuration can be arbitrarily changed. In addition, in the present embodiment, the dial 59 is fixedly disposed on the tool body 5 1. However, the following manner may be adopted, that is, the female screw portion 'in the through hole 57 is disposed to be fitted to the female The cylinder of the male screw portion of the screw portion is disposed on the dial 59, and the dial 59 can be freely rotated. Fig. 3 is a graph showing the stagnation of the contact state detecting means of the present invention. The contact state detecting means 73 is composed of a buzzer 7 1 and a circuit 74 including a power source ^. In use, the contact state detecting means 7 3 - 11 - (9) 1302295 is attached to the terminals 36, 38 of the flat type alarm 10. At this time, if the fixed contact 17 and the movable contact 18 are closed, according to the power supply 72, the terminal 38, the harness 39, the fixed contact lever, the fixed contact 17, the movable contact 18, and the active 庐 configuration] Q > ; a moving contact ί dry 19, wire harness w, excitation coil 13, wire harness 3 7, terminal 3 6 , and 袈 袈 7] ~ and each of the benefits of 7 1 constitute the guiding circuit, so that the buzzer 7 1 It sounds. Further, if the fixed contact 17 and the movable contact 18 are open, the buzzer 71 does not sound. Since the operator only needs to hear whether the buzzer 71 is sounding, whether the movable contact 18 and the fixed contact 17 are electrically conductive can be easily determined. In addition, in the present example, the buzzer 71 is used as the contact state detecting means 73. However, the buzzer may be replaced by a lamp, and the state of the contact may be determined by turning on/off, or may have a buzzer and Both sides of the lamp. Fig. 4 is a flow chart of the joint gap adjustment procedure of the flat type alarm device of the present invention. STXX is the step number. ST01: Prepare to complete the combined flat type alarm (Fig. 1 is the symbol 1 〇). At this point, 'release the lock nut (symbol 3 5 in Fig. 1) away from the housing (symbol 11 in Fig. 1) by a certain distance. ST02: Attach the flat type alarm (symbol 1 in Fig. 3) to the tool body (symbol 5 1 in Fig. 3), and connect the contact state detecting means (symbol 73 in Fig. 3) to the flat type alarm. (Figure 3 is the symbol ι〇). ST03 : Determine if the buzzer sounds. When the buzzer sounds, enter ST04. In addition, when the buzzer does not sound, enter ST06 (the buzzer does not sound -12- (10) 1302295 when the non-conduction state setting step). That is, s Τ 0 3 is the conduction state confirmation step for investigating whether the active contact 18 and the fixed contact 17 are electrically conductive in FIG. ST04 : In ST03, when the buzzer sounds, turn the adjustment screw to the right. That is, the ST04 is a non-conduction state setting step when the buzzer sounds. The steps will be described in detail with reference to FIG. Figure 5 is a description of the non-lead state setting procedure when the buzzer sounds. In Fig. 5(a), since the fixed contact I? and the movable contact ι8 are closed, the electric power is supplied from the power supply 7 2 via the fixed contact 17 and the movable contact 18 to the bee yi 71. Stealing 71 sounds. Teach the operator, "Buzzer?! When the sound comes up, turn the adjusting screw 14 to the right." Rotate the adjusting screw 14 to the right to move the fixed contact lever 6 toward the side of the spacer 23. In the case of Fig. 5(b), since the adjustment screw 14 is continuously rotated to the right by the target distance moving means 52, as a result, the movable contact lever 19 abuts against the recoil member 28 and stops moving, however, because the fixed contact lever丨6 continues to move, and the fixed contact 17 is separated from the active contact 18. The buzzer 7 停止 stops sounding at the moment of separation. The operator can stop turning the adjusting screw 1 4 at the moment when the buzzer 7 丨 stops sounding. With this job, the active contact 丨8 will move to the zero position. The zero position refers to the switching position of the contact between the movable contact 丨8 and the fixed contact 17. That is, when the contact state detecting means 73 is in the electrically conducting state, the -13-(11) 1302295 is adjusted to the non-conducting state to cause the bee to complete the non-conduction state setting step. Go back to Figure 4. ST05: Enter ST06 because the buzzer stops. S TO 6 : Turn the adjustment screw to the left until the buzzer S T 0 6 is the zero adjustment step. Refer to Figure 6 for the steps. φ Fig. 6 is an explanatory diagram of the zero point adjustment step. In Fig. 6(a), since the contact 17 and the active | are fixed, the current does not flow from the power source 7 2 to the buzzer 7 1, so the bee 3 starts. Train the operator, "When the buzzer 7 1 is not ringing, ^ turn to the left." Rotate the adjusting screw 14 to the left to move the fixed black iron core 1 2 side. In Fig. 6(b), since the target distance is moved, the adjustment screw M is rotated to the left, and as a result, the contact 17 1 8 is fixed. At this instant, the current from the power source 72 via the fixed contact: 1 8 k to the bee breaker 7 1 causes the buzzer 7 1 to sound. The operator only needs to stop the wire 14 at the moment when the buzzer 7 1 sounds. With this operation, the movable contact 18 is moved, i.e., the "contact state detecting means 73" is electrically non-rotating until the screw 14 is turned on until the state is turned on. The sounder sounds when it sounds. That is, the detailed description of the point I point 1 8 is open ί 7 1 will not ring the adjustment screw 1 4 S rod 1 6 towards the fixed 'section 5 2 will continue to abut the active contact point 7 and the movable contact stop rotation When adjusting the screwing to the zero point position, the zero point adjustment is completed. -14 (295) 1302295 In addition, in the zero point adjustment step, a screwdriver can be used instead of the target distance moving means 52. Go back to Figure 4. ST07: Enter the A ST08 because the buzzer sounds. S T 0 8 : Turn the adjusting screw to the left by a predetermined amount (1 / 2 revolution in this embodiment) °, that is, perform the contact gap securing step. Refer to Figure 7 for a detailed description of the steps. • Figure 7 is the top view of Figure 7 and Figure 7, which is an illustration of the contact gap assurance step. In Fig. 7(a), it is assumed that the scale bar 66 after the zero point adjustment step is located at the position A of the reference mark 58. The operator remembers the relationship between the position of the scale bar 66 after the zero adjustment step and the reference mark 5 8 . So far, the adjustment screw 1 4 has a pitch of, for example, 0 · 3 mm. When the adjustment screw is rotated by 1 /2, the adjustment screw 1 4 will advance or retreat by 0.1 5 mm. This 1/2 turn can be easily carried out by using the positional relationship between the reference mark 58 ... and the scale bar 66 attached to the dial 59. In Fig. 7(b), refer to the scale bar 66 and the reference mark 58···, and at the same time, turn the adjusting screw 14 to the left by 1 /2 turns, and fix the contact lever with the adjusting screw 14 (Fig. 3) Symbol 16) moves only 〇.15mm toward the side of the fixed iron core (symbol 12 in Fig. 3). That is, the contact gap is 〇.15 mm. After the operator performs the conduction state confirmation step, the non-conduction state setting step, the zero point adjustment step, and the contact gap securing step, in FIG. 3, -15-(13) 1302295 fixes the adjusting screw 14 with the lock nut 35. Adjustment of the contact gap. Further, as shown in the description of Fig. 2, when the dial 59 is rotatably mounted, it is easy to rotate the dial 59 to align one of the marks of the reference mark 5, Adjust screw 丨 4 to turn i /2 turn. At this time, the number of the reference marks 5 8 ..., for example, only 2 marks are required for 1 / 2 turn, and only 4 marks are required for 1/4 turn, as long as the rotation angle is appropriately set. Reduce the number of fiducial marks 5 8 ... to simplify the dial 5 9 . As described above, the conduction state confirmation step, the non-conduction state setting step, the zero point adjustment step, and the contact gap securing step do not require a proficiency procedure. Therefore, the operator with less experience can also adjust the contact gap easily and surely. Further, the present invention implements the contact gap securing step after the zero point adjustment step. The rotation direction of the adjustment screw in either step is the same, because the rotation direction is not necessary, so there is no delay when the adjustment screw is turned. Φ That is, the contact gap adjustment can be performed with good precision. In addition, the method of claim 1 can perform the conduction state confirmation step, the non-conduction state setting step, the zero point adjustment step, and the contact gap securing step, and therefore, the jig and device used are not limited to The form of the embodiment. Further, the jig of the second application of the patent scope may have a tool body, a target distance moving means, and a contact state detecting means, and the respective configurations are not limited to the embodiment. That is, the operation of the embodiment is generally performed by the hands, ears, and eyes of the operator, however, the actuator may be replaced by an operator -16-(14)(14)!3〇2295, or Use an electronic machine or control unit to replace the ear and eye.
