The cam pins 122, 132, 142, 152 elastically contact the cam surfaces 83, 93 due to the compression restoring force of the first urging means 100, 101.
When the cam pins 122, 132, 142, 152 are fitted in the cam recesses 84, 94 of the cam grooves 81, 91, the first and second slider divided bodies 120, 130, 140, 150 are separated as much as possible, and the opening / closing shafts 121, 131, 141, 151 are Get stuck inside. When the cam pins 122, 132, 142, 152 trace the cam surfaces 83, 93 of the cam grooves 81, 91, the first and second slider divided bodies 120, 130, 140, 150 gradually approach each other.
(Relationship between first urging means 100, 101 and second urging means 110)
The first urging means 100 and 101 are mainly for elastically projecting the opening and closing shafts 121, 131, 141, and 151 of the first and second slider divided bodies 120, 130, 140, and 150 toward the shaft insertion recess 22 of the storage body 20.

The second urging means 110 is mainly for causing the first and second lock release buttons 80 and 90 to protrude outward.
Since the first and second unlock buttons 80, 90 and the first and second slider divided bodies 120, 130, 140, 150 are connected via a link mechanism, the first urging means 100, 101 and the second urging means 110 are connected. And complement each other.

That is, the first urging means 100 and 101 act directly on the first and second slider divided bodies 120, 130, 140, and 150, but the first and second unlocking buttons 80 and 90 are directed outward through the link mechanism. There is also an action to project.
If the second urging means 110 is omitted, the first urging means 100, 101 alone will cause the first and second unlocking buttons 80, 90 to protrude outward, so the spring force is set strongly. There is a need to.

On the other hand, by adding the second urging means 110, the urging forces of the first urging means 100 and 101 can be set optimally, for example, the necessary minimum urging force.
That is, when the opened lid 30 is slightly closed, the lock recesses 85 and 95 of the first and second unlock buttons 80 and 90 are disengaged from the lock projection 25 of the storage body 20, and the lid 30 is closed by its own weight. When the lid 30 is closed, the open / close shafts 121, 131, 141, 151 of the first and second slider divided bodies 120, 130, 140, 150 come into contact with the tapered surface 23 of the shaft insertion recess 22 of the storage body 20.

At this time, since the urging force of the first urging means 100, 101 is set to the minimum necessary level, the opening / closing shafts 121, 131, 141, 151 are pushed by the tapered surface 23 by the weight of the lid 30 and retracted, and then the shaft insertion recess 22 By being fitted, the lid 30 can be locked in the closed position.
(Explanation of operation of opening and closing mechanism)
Next, the operation of the opening / closing mechanism having the above-described configuration will be described.

First, of the first and second unlock buttons 80 and 90, one of the first and second unlock buttons 80 and 90 in the direction to be opened is operated to open the closed lid 30. Just do it.
That is, as shown in FIG. 9, when the first lock release button 80 is pushed in the direction of the arrow “F1”, the first slider divided body 120 and the second slider divided body 130 approach each other as shown in FIG. Move in the direction of the distance a. For this reason, the opening / closing shaft 121 of the first slider divided body 120 and the opening / closing shaft 131 of the second slider divided body 130 are disengaged from the shaft insertion recess 22 of the storage body 20.

  Specifically, the unlocking distance for engaging and disengaging the opening / closing shafts 121 and 131 from the shaft insertion recess 22 is set to “3.1 mm”, for example. When the first unlock button 80 is pushed in, for example, by “3.5 mm”, the opening / closing shafts 121 and 131 move by the distance a described above, and the distance a is set larger than the above-described unlock distance, for example, set to “3.3 mm”. Yes. At this time, the distance L between the rod ends in FIG. 1 is shortened to the distance M as shown in FIG. Specifically, the distance L is set to, for example, “4 mm”, and the distance M is set to be less than the distance L and longer than “0 mm”, for example, “0.5 mm”.

Thereafter, when the lid body 30 is opened, as shown in FIG. 12, the lid body has the opening and closing shafts 141 and 151 of the first and second slider divided bodies 140 and 150 fitted in the shaft insertion recess 22 of the storage body 20 as fulcrums. 30 opens.
When the lid 30 is opened, the lock projection 25 of the storage body 20 is fitted into the lock recess 95 of the second lock release button 90 on the fulcrum side, so that the lid 30 is maintained in an upright state.

On the other hand, by pressing the second unlock button 90, the lid 30 can be opened from the opposite side as shown in FIG.
(Simultaneous operation of the first and second unlock buttons 80 and 90)
Next, a case where the first and second lock release buttons 80 and 90 are simultaneously operated will be described.
That is, as shown in FIG. 9, the first unlocking button 80 is pushed in the direction of the arrow “F2” and the second unlocking button 90 is pushed in the direction of the arrow “F3” at the same time.

At this time, the rod end portion of the rod portion 82 of the first lock release button 80 and the rod end portion of the rod portion 92 of the second lock release button 90 collide with each other, whereby the first and second lock release buttons 80 are provided. , 90 cannot be pushed any further.
At this time, as shown in FIG. 11, the first and second slider divided bodies 120, 130, 140, and 150 move by a distance b in a direction in which they approach.

The distance b is set such that the opening and closing shafts 121, 131, 141, and 151 of the first and second slider divided bodies 120, 130, 140, and 150 are not removed from the shaft insertion recess 22 of the storage body 20. That is, the distance b is set to be less than the distance a in FIG.
For this reason, the lid 30 cannot be opened from any direction.
Specifically, when the first and second unlock buttons 80 and 90 are simultaneously pushed, for example, by “2 mm”, both rod ends collide with each other, and the first and second unlock buttons 80 are further moved. , 90 can not be pushed in. At this time, the opening and closing shafts 121 and 131 move by the distance b described above. The distance b is set to be less than the above-described unlocking distance, for example, “1.8 mm”.
(Removal of lid 30)
Next, a method for removing the lid 30 will be described.

First, as shown in FIG. 14, one of the first and second unlock buttons 80, 90, for example, the first unlock button 80 is pressed to open the lid 30 from one side.
When the force that pushes the first unlocking button 80 is released, the first urging means 110 compresses and restores the first unlocking button 80 toward the outer side, and as shown in FIG. Both rod end portions are separated from each other, and a distance a between both rod end portions is generated.

  Therefore, the other second lock release button 90 can be pushed in, and by pressing the second lock release button 90, the lid body 30 can be removed from the storage body 20 as shown in FIG.
