In addition, at thin plate upper surface portion 33a, three limits except the limit except being connected with thin plate lateral parts 33e, through on Width X with the dogleg section that multiple slits 43 of fixing gap-forming specify, be connected to prolongation 33g, 33h, 33i of elongate width.These are for wrapping into the part of interior case 32 in mode very close to each other between thin plate bottom surface portions 33b and three thin plate lateral parts 33c, 33e, 33f.Similarly, thin plate lateral parts 33c, 33d are also wider than the width of side 32c, 32d of interior case 32.Thus, make thin plate lateral parts 33c and thin plate lateral parts 33e, 33f separately between very close to each other, make thin plate lateral parts 33d and thin plate lateral parts 33e, 33f separately between very close to each other.In addition, the peristome 33j, the notch 33k that also form connector in thin plate 33 is being detected.

Here, the minimum widith of the interval H of slit 43 is width that at least 1 wiring 42 is passed through.In addition, the end 43a of slit 43 is the wedge-type shape of top point, to make its starting point easily becoming cut-out thus to make detection thin plate 33 easily destroy.In addition, in the wiring pattern of wiring 42 being formed in the energising detecting thin plate 33, wiring 42 is arranged on intensive state all six (33a ~ 33f) that detect thin plate 33, and at least 1 wiring 42 is by between each slit 43.

The detection thin plate 33 of this structure, as shown in Figure 6, under the state of planar development, is loaded in thin plate bottom surface portions 33b by the bottom surface 32b of interior case 32, and each dogleg section is bent into right angle to the inside.The position that each crest line of each dogleg section between each of interior case 32 is corresponding, by specifying at the slit 43 arranged along the direction of each crest line.Therefore, by each dogleg section of bending, as shown in Figure 5, the interior case 32 that detected thin plate 33 wraps into can be obtained simply.Detect the thin plate lateral parts 33c ~ 33f of the surrounding of thin plate 33, be adhesively fixed with the side 32c ~ 33f of interior case 32 respectively.

In addition, detect the thin plate upper surface portion 33a of thin plate 33, be configured to cover the state of the thin plate pressing plate 35 of the upper surface 32a being loaded in interior case 32.At thin plate upper surface portion 33a, be formed with the circular through hole 59 that the rounded protrusions 35a of the through circular through hole 58 of the projection 56 of interior case 32 and thin plate pressing plate 35 is through.By projection 56 and rounded protrusions 35a are passed these through holes 58,59, thus make thin plate upper surface portion 33a with the upper surface of the state coverage thin plate pressing plate 35 that located.

Like this, the interior case 32 that detected thin plate 33 encloses and thin plate pressing plate 35, as shown in Figure 5, be housed inside in the outer box main body 36 of outer container 34, and be fixed on outer box main body 36 by bolt 38.Afterwards, cover outer case lid 37, and be fixed on outer box main body 36.Here, the rounded protrusions 35a exposed upward from the through hole 59 of thin plate upper surface portion 33a detecting thin plate 33 and outer case lid 37 are adhesively fixed mutually.Thus, detect the thin plate upper surface portion 33a of thin plate 33, to be sandwiched in the state between outer case lid 37 and thin plate pressing plate 35, be accommodated in outer container 34.In addition, outside in case lid 37, formed and embed the pilot hole 37b of projection 56, outer case lid 37 with relative to interior case 32 and outer box main body 36 by the state that located, be fixed on outer box main body 36.

--concrete structure in seal portion--

Next, with reference to Fig. 4, Fig. 7, Fig. 8 and Fig. 9, the seal portion 27 of the circuit block group 26 that tax control controls in substrate 13 is described.Fig. 7 (a) represents that tax control controls the schematic isometric of substrate 13, partial exploded perspective view under the state that Fig. 7 (b) is the outer cover component 29 having taken off seal portion 27, Fig. 7 (c) is the partial exploded perspective view taken off under the outer cover component 29 in seal portion 27 and the state of frame component 30.Fig. 8 is the schematic section in seal portion.Stereographic map Fig. 9 (a) and (b) are from face side and side, the inside to observe outer cover component 29 respectively, Fig. 9 (c) and (d) are the stereographic map of stereographic map carrying out viewing mask component 30 from face side and side, the inside and side, the inside respectively.In addition, the substrate surface 13a state upward controlling substrate 13 with tax control due to seal portion 27 is formed, therefore, in Fig. 7 to Fig. 9 of institute's reference in the explanation in seal portion 27, make tax control control substrate 13 and be expressed as the state state shown in Fig. 4 and Fig. 6 spun upside down.In addition, because the seal portion 25 (with reference to Fig. 6) in EJ tax-controlling memory substrate 10 possesses the structure same with seal portion 27, after therefore seal portion 27 being described, the description thereof will be omitted.

From Fig. 7 (b), control in substrate 13 in tax control, be provided with the circuit block group 26 comprising program tamper confirmation CPU18, ROM19, RAM20, circuit block group 26 is the seal portions 27 carrying out seal by employing seal structure of the present utility model.As shown in Fig. 7 (c), seal portion 27 possesses: hardening of resin layer 28, outer cover component 29 and the frame component 30 the circuit block group 26 of the substrate surface 13a being arranged on tax control control substrate 13 covered.

From Fig. 7 and Fig. 8, frame component 30 is rectangular, is metal or resinous component.Frame component 30, by bonding agent, to surround the state of circuit block group 26, is fixed on substrate surface 13a.Thus, by substrate surface 13a and frame component 30, be formed in the recess 65 of the substrate surface upper opening of the side contrary with substrate surface 13a, circuit block group 26 is positioned at the part to the substrate surface 13a that the bottom surface of recess 65 specifies.

Hardening of resin layer 28 is formed as the state of filling up recess 65, and circuit block group 26 is covered completely.Hardening of resin layer 28 is the layers such as by making the epoxy cure flowing into recess 65 with molten condition be formed.As hardening of resin layer 28, the resin beyond epoxy resin also can be used.

Outer cover component 29 is the board members of the rectangle be made up of metal or resin-made.Outer cover component 29, to cover the state of the hardening of resin layer 28 exposed from the opening of recess 65 completely, is installed in the rectangular box-like end face 30a of the side contrary with the substrate surface 13a of frame component 30.Outer cover component 29 by installing before being filled in the hardening of resin in recess 65, thus is adhesively fixed on the surface of hardening of resin layer 28.Like this, clip hardening of resin layer 28 and from the side contrary with substrate surface 13a to be installed on the outer cover component 29 of this hardening of resin layer 28, when observing from the direction orthogonal with substrate surface 13a, comprise the configuring area of the circuit block group 26 in substrate surface 13a.

As shown in Figure 8, in outer cover component 29,2 projections 66,67 are integrally formed.Outer cover component 29 is buried in the state in hardening of resin layer 28 with projection 66,67, be adhesively fixed on hardening of resin layer 28.As shown in Figure 8, projection 66,67, from the inside 29a towards the hardening of resin layer 28 outer cover component 29, is given prominence to vertically towards substrate surface 13a.In addition, tip portion 66a, the 67a of the substrate surface 13a side in these projections 66,67 are the directions different from projected direction, are be bent into right angle in this example.

With reference to Fig. 9, the structure of frame component 30 and outer cover component 29 is illustrated in further detail.Frame component 30 is frame components of square-section, and this square-section is the size of the circuit block group 26 that can comprise seal object.The rectangular box-like end face 30b be adhesively fixed with the substrate surface 13a in frame component 30 is tabular surface, the rectangular box-like end face 30a of opposite side be inner periphery side portion be divided into low go out the end face of stairstepping of a section.In addition, an angle part of rectangular box-like end face 30a becomes the bight 30c of location.

Outer cover component 29 is certain thickness board members of the rectangular profile of entirety, possesses the stair-stepping peripheral end face 29b corresponding with the rectangular box-like end face 30a on the upside of frame component 30.In addition, the bight 29c of the location corresponding with the bight 30c of frame component 30 is possessed.Therefore, for the frame component 30 being fixed on substrate surface 13a, can locate simply and outer cover component 29 is installed.

In the inside 29a of outer cover component 29, formed with the projection 66,67 of fixing spaced and parallel extension.In a projection 66, formed at the middle body of its length direction and be bent into right angle and the tip portion 66a extended.In another projection 67, formed in the two end portions of its length direction and be bent into right angle and a pair tip portion 67a extended to same direction.Tip portion 66a and a pair tip portion 67a bends in the direction away from each other.The number of projection 66,67, shape also can be different from illustrated number, shape, and the wrap direction of these tip portion also can be different direction.

In the seal portion 27 of this structure, hardening of resin layer 28 is covered by outer cover component 29 and frame component 30.In order to remove hardening of resin layer 28, need to destroy outer cover component 29.Because the projection 66,67 of outer cover component 29 is buried and is fixed on hardening of resin layer 28, be therefore difficult to outer cover component 29 to take off from hardening of resin layer 28.Therefore, the improper contact for circuit block group 26 is very difficult.

If peeled off from hardening of resin layer 28 by outer cover component 29 forcibly, then projection 66,67 is cut by the root of the inside 29a from outer cover component 29, and remains in hardening of resin layer 28.Therefore, the vestige of the improper contact that circuit block group 26 is carried out can be remained.In addition, when destroy outer cover component 29 and hardening of resin layer 28 come wrongly contact circuit parts group 26, even if again carry out seal circuit block group 26 by hardening of resin layer 28, the outer cover component 29 be destroyed can not be installed, be difficult to revert to original seal portion 27.Therefore, it is possible to positively know improper contact.

In addition, if as outer cover component 29, use by compared with hardening of resin layer 28 based on the component that the material that the shape retention heated is poor is formed, then at heated resin hardened layer 28 and when peeling off, outer cover component 29 can be first destroyed.Similarly, if compared with the bond strength between outer cover component 29 and hardening of resin layer 28, the bending strength of outer cover component is lower, then, before being peeled off from hardening of resin layer 28 by outer cover component 29, outer cover component 29 can positively be destroyed.

--other embodiment--

In addition, except detecting thin plate 33, other detection thin plate can also also be configured in the inside of interior case 32.Such as, in Fig. 4 (a), position etc. corresponding to the peristome 55 of interior case 32 can be arranged on, configuration detection thin plate 33A with in order to configure connector 5.Thus, if via the peristome 55 of connector 5, contact wrongly from outside, then can cause detecting thin plate 33A and be destroyed.

In addition, although in the above example, the entirety of interior case is detected thin plate and wraps into, also can only in the part of case be detected thin plate and wrap into.In addition, although clip the part detecting thin plate between thin plate pressing plate and outer case lid, also detection thin plate can be clipped between the position beyond the outer case lid in thin plate pressing plate and outer container.Further, as being formed at the wiring pattern detecting thin plate, various pattern can be adopted.
