Explanation now is applied to traction processing apparatus with e-machine of the present invention.Fig. 1 is the oblique drawing of the traction processing apparatus of embodiments of the invention.Traction processing apparatus 1 have the input transaction data keyboard 2, show the transaction data etc. of input display part 3, print the chopping machine 4 of the receipt that is printed on above-mentioned transaction data and take in cash or the cash casket 5 of commodity paper etc.Fig. 2 is the oblique drawing of the traction processing apparatus of the state after lid is taken off.There are the space of the electric substrate 11 that the memory device that has the accumulation store transactional data is set and the space that chopping machine 4 is set in the inside of traction processing apparatus 1, and these two spaces separate with next door 12.Each space is respectively equipped with covers 13,14.

Traction processing apparatus 1 will be presented on the display part 3 from the transaction data of keyboard 2 inputs, and prints the receipt that is printed on this transaction data with chopping machine 4.The transaction data of input also is stored in the memory device on the electric substrate 11 by accumulation.The lid 13 that covering is provided with the space of electric substrate 11 has been added seal and can not arbitrarily have been opened and closed.The back adds explanation the method for this seal.

On the other hand, cover the lid 14 that chopping machine 4 is set and arbitrarily to open and close (not adding seal).Therefore, the replacing of the coil paper of using on the chopping machine 4 can not be restricted, and can change at any time.

Fig. 3 (A) expression will cover the lid in the space that electric substrate is set and load onto, and the scheme drawing of the state of the lid that will cover the space that chopping machine is set after taking off, Fig. 3 (B) is the enlarged drawing of the A portion shown in Fig. 3 (A).Shown in Fig. 3 (B), under the state of loading onto the lid 13 that covers the space that electric substrate 11 is set, as shown in the figure, the upper part in above-mentioned next door 12 and lid 13 end portion be state in an overlapping, does not have to make metal bar etc. to lead to the gap in the space that electric substrate 11 is set.Fig. 4 is the diagrammatic top view after two of traction processing apparatus lids 13,14 are taken off.Fig. 5 is the enlarged drawing of B portion shown in Figure 4.As shown in Figure 4, next door 12 is made of two boards 12a, 12b.Plate 12a, the front end of 12b roughly is zigzag, this two plate 12a, the part overlaid that roughly is zigzag of 12b.This lap does not contact and forms a short space, and this space usefulness connects the wiring path of the cable 15 of electric substrate 11 and chopping machine 4.Here, as shown in the figure, the wiring path of cable 15 is zigzag, so cable 15 crankle in this wiring path.

Under the state after the lid 14 that will cover the space that chopping machine 4 is set unloads, when inserting metal bar in the wiring path with electric substrate 11 bonded assembly cables 15 (with metal bar when the direction of C shown in Figure 5 is inserted), the front end of the metal bar of this insertion etc. can be met plate 12a, therefore even the wiring path from cable 15 such as metal bar is inserted, can not invade the space that electric substrate 11 is set.That is, can not make the front end of metal bar touch electric substrate 11, therefore can not realize rewriting the impropriety of the sales volume data of storing in the memory device.In addition, owing to form the wiring path of cable 15 circuitously, so when external force is added on this cable 15, this external force is cancelled in wiring path, this external force can directly not be added to the connecting bridge of cable 15 and electric substrate 11, can prevent that connecting bridge from being broken, can also improve the reliability of traction processing apparatus 1.

Like this, only otherwise the lid 13 that will cover the space that electric substrate 11 is set unload down, just can not contact electricity submounts 11, so after this lid 13 carried out seal, (for example people except that official) can not open-close lid 13 except that specific people.Thereby can forbid the people's contact electricity submounts 11 except that fixed people.

Now illustrate covering 13 methods that add seal.Fig. 6 is the cross sectional drawing and the recess enlarged drawing of the traction processing apparatus 1 of this embodiment.Shown in Fig. 6 (A), on lid 13, be provided with recess 21, the bottom surface of recess 21 is provided with opening.Will cover 13 be installed on the main body after, be provided with the screw bearing 22 of band screw hole in the position relative with the opening (screwing through hole) established on the bottom surface of recess 21.Not shown recess 21 and screw bearing 22 among Fig. 1 to Fig. 5.This is will cover 13 and the structure that is fixed together of main body with a screw.Fig. 6 (B) is the enlarged drawing of the D portion among Fig. 6 (A).Recess 21 is truncated cone shape, and its bottom area is bigger than top area.

Add seal in the following order.To cover 13 install on the main body after, utilize the screw 23 pass the opening on the bottom surface that is located at recess 21, main body and lid 13 are fixed together.At this moment the head of screw 23 is the state of imbedding recess 21.With lead, soft metals such as zinc, scolding tin 24 insert and the skull of screw 23 are lived then.On the surface of the soft metal 24 of this insertion, impress then, finished and covered 13 seal.

To cover 13 add seal after, in order to unload lower cover 13, just must unload screw 23 then with pressing the soft metal of seal to take out from recess 21.Yet, suppose insertion recesses 21 such as metal bars, desire is taken out soft metal 24 from recess 21, the load that then is added on the soft metal 24 is very big, in addition, because recess 21 is frustum-like shape, thus the area of the soft metal that inserts than the conveying end that inserts member 24 (insert member 24 the insertion mouth, be the upper part of recess) area big, just can not take out if do not destroy the original state of the soft metal that has impression etc.Therefore when the people beyond the supvr will cover 13 open after, be easy to judgement.

Owing to as above constitute e-machine, can improve the reliability of the seal on the e-machine, therefore can prevent contact to store the memory substrate 11 of sales volume data, rewrite the sales volume data so that the impropriety of the tax that reduces to impose.

In the above-described embodiments, be that example has illustrated e-machine of the present invention with the traction processing apparatus, but self-evident, the present invention also can be applied to other e-machine.In addition, though make the shape of recess 21 be frustum-like shape, also can adopt shape shown in Figure 7.In addition, though what adopt is will cover 13 and the structure that is fixed together of main body with a screw, not limit by this.Also can adopt the structure of screw retention such as 2,3.With a plurality of screw retention the time, can also can select a part of screw to whole screws seal in addition, only these screws are added seal.

As mentioned above, if adopt the present invention, then the insertion member that covers owing to the screw head with stationary body and lid is not given prominence on the surface of lid, just is difficult to taking-up so do not destroy the original state of this insertion member.Therefore can improve the reliability of the seal of e-machine.

In addition, because the area of the bottom surface portions of recess is bigger than the area of upper part, just can not take out the insertion member that inserts recess so do not destroy original state.Therefore can further improve the reliability of seal.

Moreover, owing to use soft metal, insert the seal processing that member covers screw head so can easily utilize as inserting member.
