Thereafter, the second side plate portion 22 is bent at a right angle with respect to the bottom plate portion 12 around the folding line 36. Thereby, it combines so that the 1st side plate part 21-the 4th side plate part 24 may become a square cylinder shape. This state is shown in FIG. In addition, after forming a square tube in this way, you may make it incorporate the sensor 2 in this inside.

  By passing through the sixth packaging step, the tip of the buffer convex portion 20b1 of the buffer plate portion 20 is covered with the joint piece 24a, and the upper portion 20b of the buffer plate portion 20 is connected to the package body 11 via the joint piece 24a. The first side plate portion 21 and the second side plate portion 22 are sandwiched from before and after. At the same time, a buffer space S (see FIG. 8) is formed between the support plate 15 and the inner surface of the second side plate 22 facing the support plate 15. The depth in the front-rear direction of the buffer space S corresponds to a dimension obtained by adding the thickness of the joining piece 24a and the protruding length of the buffer convex portion 20b1, and the front portion 3a of the sensor 2 is disposed in a part of the buffer space S. The front portion 3a and the support plate portion 15 are separated by a distance larger than the thickness of the front portion 3a.

  As a seventh packaging step, the pair of inner flaps 25.26 and the pair of outer flaps 27, 28 are bent to close the upper end opening of the square tube.

  That is, first, the inner flap 25 is bent at a right angle with respect to the third side plate portion 23 with the folding line 43 as the center, and the inner flap 26 is formed with the fourth side plate portion 24 with the folding line 44 as the center. Bend it to make a right angle to it. Next, the outer flap 27 is bent so as to be perpendicular to the first side plate portion 21 with the folding line 41 as the center, and is covered with the inner flaps 25 and 26, and the outer flap 28 with the folding line 42 as the center. Is bent at a right angle with respect to the second side plate portion 22 and covered with the inner flaps 25 and 26.

  And as the last 8th packaging process, the adhesive tape 10 is stuck on the upper surface part of the said square tube, covering the joint of the outer flaps 27 and 28, and the outer flaps 27 and 28 are hold | maintained in the closed state. The state where the packaging is completed in this way is shown in FIGS.

  Further, the package 11 can be unpacked and the internal sensor 2 can be taken out by a procedure reverse to the assembly procedure described above. In this case, the sensor 2 opens the outer flaps 27 and 28 and the inner flaps 25 and 26 as shown in FIG. 6, and opens the upper end of the square tube formed by the first side plate portion 21 to the fourth side plate portion 24. In this state, by moving the pressing portion 15a to open the support hole 16 upward, the sensor 2 can be grasped and taken out from above the square tube.

  In the state where the sensor 2 is packaged as described above, a rectangular tube whose upper end is opened is formed by connecting the first side plate portion 21 to the fourth side plate portion 24, and is arranged in this rectangular tube. The first inner side plate portion 13, the support plate portion 15, and the buffer plate portion 20 that are connected to the bottom plate portion 12 are integrally continuous, and the buffer plate portion 20 is connected to the first side plate portion 21 and the second plate portion 21. It is provided so that it may be pinched | interposed in the front-back direction with the side-plate part 22 of this. For this reason, it is prevented that the 1st internal side board part 13, the support board part 15, and the buffer board part 20 shake within a square tube. Moreover, as described above, the movement of the sensor 2 in the front-rear direction, the left-right direction, the up-down direction, and the circumferential direction is restricted with respect to the support plate portion 15. Furthermore, the front ends of the pair of leaf springs 9 are in contact with the inner surface of the package 11, and the movement of the sensor 2 is also stopped in this respect. Therefore, the support state of the packaged sensor 2 is stabilized.

  As described above, the package 11 supports the sensor 2 by fitting the sensor body 3 of the sensor 2 into the support hole 16 of the support plate portion 15. Thereby, it is not necessary to provide a plurality of seats for supporting the sensor 2 by bending. At the same time, the buffer space S in which the front portion 3a of the sensor 2 supported by the support plate portion 15 is disposed is secured by the buffer convex portion 20b1 provided in the buffer plate portion 20, so that the buffer space S is formed. There is no need to form a plurality of bent portions serving as spacers. Therefore, the configuration is simple, and assembly and unpacking can be easily performed as described above.

  In a state where the sensor 2 is packaged, the sensor main body 3 is made of a portion other than the support plate portion 15 of the package body 11, that is, the buffer plate portion 20, the first inner side plate portion 13, and the second inner side plate. It can be packaged such that it does not contact the portion 14 and does not contact any of the first side plate portion 21 to the fourth side plate portion 24, the bottom plate portion 12, and the inner and outer flaps 25 to 28 that form a rectangular tube. In other words, the sensor 2 can be supported by the support plate portion 15 in the same state as when the sensor body 3 floats in the air. For this reason, the buffering performance of the sensor body 3 against an external force acting on any one of the six surfaces of the package 11 can be improved.

  Along with this, the buffer convex portion 20b1 for securing the buffer space S is not in contact with the sensor, and the front portion 3a of the sensor 2 from which the cover 7 is projected is located in the buffer space S secured by the buffer convex portion 20b1. It is stored. Therefore, it is possible to suppress the buffer convex portion 20b1 and the second side plate portion 22 from rubbing against the front portion 3a of the sensor main body 3 and scratching the sensor main body 3.

  Further, the assembled package 11 includes the second inner side plate portion 14 that is folded into the bottom plate portion 12 so as to be perpendicular to the bottom plate portion 12 around the folding line 32, and the buffer plate portion 20 and the fourth plate 11. Provided between the side plate portion 24 and the second inner side plate portion 14 to lock the buffer plate portion 20 to support the first side plate portion 21 and the second side plate portion 22 from the inside of the square tube. it can. Thereby, the assembly strength of the package 11 can be improved. At the same time, entry of dust from the bottom plate portion 12 and the fourth side plate portion 24 can be suppressed. Moreover, since the buffer plate portion 20 and the support plate portion 15 are properly positioned by locking the buffer plate portion 20 to the second inner side plate portion 14, the assembly strength of the packaging body 11 is also improved in this respect. it can.

  In addition, the assembled package 11 is provided with joining pieces 23a, 24a connected to the inner surface of the second side plate portion 22 on the third side plate portion 23 and the fourth side plate portion 24, respectively. The joining piece 24 a bent from the side plate portion 24 is sandwiched between the second side plate portion 22 and the buffer convex portion 20 b 1 of the buffer plate portion 20. Accordingly, the second side plate portion is supported by the buffer plate portion 20 from the inside of the package body 11 via the joining piece 24 a having a width wider than the thickness of the buffer plate portion 20. Therefore, the assembly strength of the package 11 is improved, and it is possible to effectively suppress the second side plate portion 22 from being deformed so as to narrow the buffer space S by an external force. In addition, the intrusion of dust from the second side plate portion 22 and the third side plate portion 23 and between the second side plate portion 22 and the fourth side plate portion 24 is suppressed by the joining pieces 23a and 24a. it can.

  The first inner side plate portion 13, the support plate portion 15, and the buffer plate portion 20 support the outer flaps 27 and 28 and the bottom plate portion 12 from the inside of the package 11 through the inner flaps 25 and 26. As a result, the strength of the package 11 in the vertical direction can be improved.
