Transaction processing device

Industrial use

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic apparatus for fixing a cover to a main body by a screw, and more particularly to an electronic apparatus for sealing a cover fixed to a main body.

Conventional technology

In foreign countries, there are countries that have legislated laws collecting taxes on sales in stores. In such a country, a transaction processing apparatus having an electronic board having a memory for storing and storing transaction data is installed in a store, and a tax amount of tax to be collected based on the accumulated transaction data stored in the memory is determined have. However, if the person in charge of the store opens the cover, and the contents of the transaction data can be rewritten in contact with the memory board, it will not be possible to accurately collect the tax. In order to prevent such unfaithfulness, after the lid is fixed to the main body by screws, the head of the projected screw is covered with a soft metal such as lead, the surface of the soft metal is engraved, have.

However, as described above, since the head of the screw fixing the cover to the main body is sealed with the soft metal such as lead, the soft metal protrudes from the surface of the cover, and the engraved engraving on the surface of the soft metal is torn It can be easily carried out. Therefore, there is a drawback that the reliability of sealing is low and the effect of preventing the tampering, which is in contact with the memory substrate and rewrites the contents of the memory, is low.

It is an object of the present invention to provide an electronic apparatus with improved sealing reliability by making it impossible to fix a circular metal mold such as lead sealed in a head of a screw after the screw cap is fixed to the main body without collapsing have.

The electronic apparatus of the present invention is characterized by comprising a cover having a recess in which the head of the screw is buried when fixed to the main body by a screw and an insertion member inserted into the recess after fixing the cover to the main body do.

Further, the main body has at least an electronic substrate inside.

It is also characterized by a transaction data input means for inputting transaction data and a settlement means for performing a settlement process based on the input transaction data.

Further, the concave portion is characterized in that the area of the bottom portion is larger than the top portion.

The electronic substrate is a memory substrate for storing input data.

Further, the insertion member is characterized by being a soft metal such as lead, zinc, or solder.

Action

In the electronic apparatus of the present invention, when the lid is fixed to the main body by screws, the head of the screw is buried in the recess. Then, the insertion member inserted into the recess covers the head of the screw, and seals the electronic device. At this time, since the insertion member inserted into the concave portion does not protrude from the surface of the lid, it is difficult to untie the insertion member without collapsing the circular shape. Therefore, the reliability of sealing of the electronic device can be improved.

The electronic device can be applied to an ECR or the like that performs settlement processing based on inputted transaction data. However, if the above configuration is made under a system of collecting taxes on sales, the tax collection can be accurately performed.

Further, since the bottom face portion of the concave portion is made larger in area than the top face portion, it is not possible to detach the insertion member from the concave portion without collapsing the circular shape. Therefore, it is possible to further improve the reliability of sealing.

Moreover, by using the soft metal as the insertion member, the sealing process is facilitated.

Example

Here, the electronic apparatus of the present invention is applied to a transaction processing apparatus. FIG. 1 is a perspective view of a transaction processing apparatus according to an embodiment of the present invention. FIG. The transaction processing apparatus 1 includes a keyboard 2 for inputting transaction data, a display unit 3 for displaying inputted transaction data and the like, a printer 4 for issuing a receipt printed with the transaction data, And a cashbox 5 for accommodating the cashbox 5 and the like. 2 is a perspective view of the transaction processing apparatus with the cover removed. The transaction processing apparatus 1 includes a space in which an electronic substrate 11 having a memory for storing transaction data therein is stored and a space in which a printer 4 is installed. These spaces are separated by a partition wall 12 . Further, lids 13 and 14 are provided in the respective spaces, respectively.

The transaction processing apparatus 1 displays the transaction data inputted from the keyboard 2 on the display unit 3 and issues a receipt printed by the printer 4 on the transaction data. The inputted transaction data is stored in the memory of the electronic board 11 and stored. The lid 13 covering the space where the electronic substrate 11 is provided is sealed so that it can not be opened and closed freely. The sealing method will be described later.

On the other hand, the lid 14 covering the space in which the printer 4 is installed can be freely opened and closed (not sealed). Therefore, the exchange of the roll paper used in the printer 4 is not limited and can be freely performed.

3 (A) is a schematic view showing a state in which a lid covering a space where the electronic board is installed is attached and a lid covering the space where the printer is installed is removed. Fig. 3 (B) It is an enlarged view of part A. The upper end of the partition wall 12 and the lower end of the lid 13 are connected to each other as shown in Fig. 3 (B) And there is no clearance for allowing the metal rods or the like to pass through the space where the electronic substrate 11 is provided. FIG. 4 is a schematic plan view showing the two lids 13, 14 of the transaction processing apparatus removed; FIG. FIG. 5 is an enlarged view of part B shown in FIG. As shown in FIG. 4, the partition wall 12 is composed of two plates 12a and 12b. The tips of the plates 12a and 12b are formed in a substantially Z-shape, and substantially Z-shaped portions of the two plates 12a and 12b are overlapped. The overlapped portion is not contacted and a small space is formed, and this space is used as a wiring path of the cable 15 connecting the electronic substrate 11 and the printer 4. Here, since the wiring of the cable 15 is formed in a Z-shape as shown in the figure, the cable 15 becomes meandering in this wiring route.

When the metal rod is inserted into the wiring route of the cable 15 connected to the electronic board 11 in a state where the lid 14 covering the space where the printer 4 is installed is removed The tip end of the inserted metal rod or the like hits the plate 12a so that even when a metal rod or the like is inserted from the wiring route of the cable 15, There is no number. In other words, since it is impossible to bring the tip of the metal rod into contact with the electronic substrate 11, it is impossible to negate the rewriting of the sales data stored in the memory. This external force is absorbed in the wiring path when an external force is applied to the cable 15 and the external force is directly applied to the connection portion between the cable 15 and the electronic board 11 And the reliability of the transaction processing apparatus 1 can be improved.

The cover 13 can not be connected to the electronic board 11 unless the cover 13 covering the space in which the electronic board 11 is provided is detached so that the cover 13 is sealed so that a person other than the specific person It is impossible for a person to open and close the lid 13. Therefore, it is possible to prohibit a person other than the specific person from contacting the electronic substrate 11. [

Sealing of the lid 13 will be described. 6 (A) and 6 (B) are enlarged views of a cross-sectional view and a recessed portion of the transaction processing apparatus 1 of the present embodiment. As shown in Fig. 6 (A), the lid 13 is provided with a recess 21 in which an opening is formed on the bottom surface. The main body is provided with a screw receiving table 22 having a screw hole at a position where an opening (screw through hole) formed in the bottom surface of the recess 21 faces when the lid 13 is attached. Also, in the first to fifth drawings, the recess 21 and the screw receiving table 22 are not shown. Further, the lid 13 and the main body are structured so as to be fixed by a single screw. 6 (B) is an enlarged view of a portion D in FIG. 6 (A). The concave portion 21 has a shape of a truncated cone having a larger area than the upper surface portion of the bottom surface portion.

Sealing is done in the following order. After attaching the lid 13 to the main body, the main body and the lid 13 are fixed by the screw 23 through the opening formed in the bottom surface of the recess 21. At this time, the head of the screw 23 is buried in the concave portion 21. Then, the soft metal 24 such as lead, zinc, or solder is inserted into the concave portion 21 so as to cover the head of the screw 23. Then, the surface of the inserted soft metal 24 is imprinted, and sealing of the lid 13 is completed.

In order to remove the lid after sealing the lid 13, the screw 23 must be pulled out after the soft metal imprinted from the recess 21 is pulled out. However, if a metal rod or the like is inserted into the concave portion 21 and the soft metal 24 is torn off from the concave portion 21, the load applied to the soft metal 24 is large. The inserted soft metal collapses the circular shape of the soft metal 24 including the engraving etc. because the inserted soft metal has an area larger than the outflow opening of the insertion member 24 (the upper opening of the insertion member 24) It is impossible to untie it. Therefore, when a person other than the manager opens the lid 13, this can be immediately known.

By configuring the electronic apparatus as described above, it is possible to improve the reliability of the sealing in the electronic apparatus. Therefore, it is possible to reduce the tax collected by rewriting the sales data in contact with the memory board 11 storing the sales data Can be prevented.

In the above embodiment, the electronic device of the present invention is described as an example of a transaction processing device, but it goes without saying that it may be applied to other electronic devices. Further, although the shape of the recess 21 is a truncated cone shape, it is also possible to adopt a shape as shown in Fig. The lid 13 and the body are fixed by a single screw. However, the lid 13 and the body may be fixed by two screws or three screws. Further, in the case of fixing with a plurality of screws, all the screws may be sealed, or a part of screws may be selected and these screws may be sealed.

As described above, according to the present invention, since the insertion member covering the head of the screw fixing the main body and the lid is not protruded from the surface of the lid, it is difficult to detach the circular shape of the insertion member without collapsing. Therefore, the reliability of sealing of the electronic device can be improved.

Further, since the bottom face portion of the recess portion has a larger area than the upper face portion, it is impossible to untie the circular shape of the insertion member inserted into the recess without collapsing. Therefore, the reliability of sealing can be further improved. Moreover, since the soft metal is used as the insertion member, the sealing process of covering the head of the screw by the insertion member can be facilitated.
