As shown in Figure 8, card shaped body 2 possesses flat tray main body 70, is configured in the leading edge lid 71 of the nearly body side of pallet plug direction of tray main body 70, and leading edge lid 71 is by the pallet plug direction engaged at end of metal attachment 72,72 and tray main body 70.
Tray main body 70 forms tabular by insulating properties synthetic resin material, is formed with the card accommodation section 73 of the concavity that holds card A in one side portion.
In addition, the inboard edge of pallet plug direction of tray main body 70 forms the stop part 75 that teat 74 stops that stops that pushes direction inboard that is configured in molding 10, when card shaped body 2 is inserted to housing 4, this stop part 75 is pushed to limit positions by the position that teat 74 stops that stops of housing 4 as card shaped body, and restriction pushes limit positions to the movement that pushes side with respect to the card shaped body of card shaped body 2.
In addition, on tray main body 70, the portion that is linked 22 of the formation of pallet plug direction inboard portion and slide block 20 chimeric coordinate notch 76, the inner edge of this cooperation notch 76 coordinates with the portion of being linked 22, and interlock is the inboard edge butt of pallet plug direction with tray main body 70 by engagement tabs 26, thereby the push-on force acting on card shaped body 2 can be passed to slide block 20, and, can act on force transmission on slide block 20 to card shaped body 2 by releasing spring 25.
Therefore, slide block 20 together moves with card shaped body 2 under the portion of being linked 22 state chimeric with coordinating notch 76, and, by relatively independent to pushing side disengaging from card shaped body 2.
And, in figure, symbol 77 is switch contact exposed divisions, expose through this notch 77 the inboard edge of card A, the inboard edge of this card A contacts with the operating contact 78a of switch 78 with the detection that is formed in housing 4 inboard configurations, by pushing, operating contact 78a with by operating contact 78b, contacted or depart from, the ON/OFF that carries out thus switch 78 switches action, insertion that can test card A.
Leading edge lid 71 forms rectangular-shaped, sidepiece a side is formed on the insertion pilot hole 79 connecting in card shaped body 2 plug directions, through this, insert pilot hole 79, can be from housing 4 sidepieces, namely the nearly body side opening of slide block moving part 14 inserts pin-shaped wedge parts 80.
Then,, based on Fig. 9, for the insert action of card shaped body 2, describe.And Fig. 9 (a) is the state from housing 4 is pulled out by card shaped body 2, slide block 20 is stressed from releasing spring 25, in the S1 of origin position shown in figure, follows in this, and banking pin portion 33 is positioned at the origin position P1 of the nearly body side of pin gathering sill 42 Nei Bingyong road portions 55.
Then, as shown in Figure 9 (b), when card shaped body 2 is inserted into the assigned position in card shaped body insertion section 3, chimeric with the portion that is linked 22 of slide block 20 within coordinating notch 76, and, the protuberance 31a of half locking plate 31 coordinates with recess 32 with half lock, and card shaped body 2 is integrated with the state that can load and unload with slide block 20.Now, during banking pin Bu33Wang road portion 50 interior releasing push-on force, slide block 20 is released spring 25 active force in utilizing forced back towards the state of origin position S1.
From this state as shown in Figure 9 (c), when card shaped body 2 is further pushed into card shaped body and pushes limit positions, by the push-on force that engagement tabs 26 is used in interlock and the portion 22 that is linked acts on card shaped body 2, be delivered to slide block 20, slide block 20 moves to interlock limit positions S2 with the active force that card shaped body 2 together overcomes release spring 25, interlock with it, returning to rake 60 and preventing from returning end difference 56 toward road portion 50 crossed by banking pin portion 33, fall into the action permission portion 52 that pushes, and, slide into push action in permission portion 52 in position P2.
Like this, in initial the pushing in action of card shaped body 2, banking pin portion 33 dodges to pushing in action permission portion 52, does not hinder the movement of card shaped body 2 and slide block 20.
In addition, card shaped body 2 pushes limit positions with respect to this card shaped body and is restricted to the movement that pushes side, so the position of slide block 20 be now can with card shaped body 2 mobile interlock limit positions S2 together, utilize the push operation of card shaped body 2, slide block 20 can not be with respect to this limit positions S2 that links to pushing side shifting.
Then, from the state of Fig. 9 (c), remove the power that pushes direction of card shaped body 2, slide block 20 utilizes release spring 25 stressed in release direction, this acts on, and active force on slide block 20 is used engagement tabs 26 by interlock and the portion 22 that is linked passes to card shaped body 2, card shaped body 2 is pushed back to the insertion position of regulation shown in Fig. 9 (d), and slide block 20 forced back towards latched position S3.
Thus, as shown in Figure 5, because banking pin portion 33 coordinates with heart type cam 42, banking pin portion 33 is restricted in the movement of releasing direction, so slide block 20 is restricted at latched position S3 by lock pin 28 in the movement of releasing direction.
Even under this state, also card shaped body 2 can be pushed into card shaped body and push limit positions, but as implied above, slide block 20 can together move before interlock limit positions S2 with card shaped body 2.
In addition, under this state, in banking pin portion 33, be positioned at the position P3 that coordinates with heart type cam 42 and slide block 20 move up in the side of pushing in the situation that, banking pin portion 33 links with it and is removing the interior slip with guiding road portion 54.
Therefore, because releasing is with preventing that returning to end difference 58 is formed on the position of staggering in slide block moving direction inboard with the position P4 that guides the banking pin portion 33 in road portion 54 with respect to the upper releasing of interlock limit positions S2, so utilize card shaped body 2 once again push action, banking pin portion 33 can not arrive to removing with preventing from returning end difference 58, act on after the push-on force releasing on card shaped body 2, utilize the active force of releasing spring 25 that slide block 20 is pushed back to latched position S3, banking pin portion 33 also forced back towards the position P3 coordinating with heart type cam 42.
Thus, even in the situation that due to the falling of electronic equipment, contact etc. causes card shaped body 2 to act on the load that card pushes direction accidentally, also due to card shaped body 2 once again push action, slide block 20 is not disengaged at the mobile restriction of releasing direction, therefore can prevents the unexpected discharge of card shaped body 2.
On the other hand, the releasing of this lock-out state can be only by carrying out as shown in Figure 10 (d)～(g): use wedge parts 80 to make slide block 20 depart from and move to latch-release position S4 to pushing side from card shaped body 2, namely make banking pin portion 33 cross to remove to move to preventing from returning end difference 58 the position P5 that arrives past road portion 51.
First, as shown in Figure 10 (d), pin-shaped wedge parts 80 are inserted to slide block moving part 14 through inserting pilot hole 79, make the front end of wedge parts 80 and the nearly body side butt that is pushed into sheet 24 of slide block 20.
Then, from this state, further use wedge parts 80 to push slide block 20, card shaped body 2 together moves, and is pushing in limit positions, and the inboard edge of card shaped body 2 (stop part 75) is blocked teat 74 and stops, card shaped body 2 is restricted in the movement that pushes direction.
