(Background to this disclosure)
Information processing devices are required to ensure security. In particular, since a payment terminal, which is an information processing device having a payment function, handles money, it is required to ensure a high degree of security (tamper resistance). Tamper resistance refers to a state in which a device or device is less likely to be tampered with by analyzing, reading, or tampering with the internal structure or recorded data from the outside.

In recent years, payment terminals have been realized in the form of payment terminals arranged around store registers, smartphones, tablet terminals, and the like.

The information processing device generally includes a screen for presenting information. The screen may be, for example, a liquid crystal screen, but may be a screen of another format. A person who intends to perform the above-mentioned falsification (hereinafter referred to as "unauthorized accessor") may attempt to illegally access the inside of the information processing device by cutting, for example, the edge of the liquid crystal screen. obtain. In order to ensure the tamper resistance of the information processing device, it is important that the information processing device is provided with protective measures against unauthorized access due to disconnection of the screen as described above.

This is to avoid unnecessary redundancy of the following description and to facilitate the understanding of those skilled in the art. It should be noted that the accompanying drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

(Overview of information processing equipment)
FIG. 1 is a diagram showing an example of the information processing apparatus 1 of the present disclosure, which is (a) a top view and (b) a side view.

The information processing device 1 as an example of the present disclosure may be a composite payment terminal capable of allowing a user (purchaser of a product, etc.) to select a plurality of payment methods. The information processing device 1 may be placed around a register on the counter of a store (convenience store, restaurant, bookstore, etc.). The information processing device 1 which is an example of the present disclosure includes a user surface 3 used by the user and a display surface 2 used by a store clerk or the like.

The information processing device 1 which is an example of the present disclosure has a magnetic card payment slot 4, a contact type IC card payment slot 5, and a touch area 6 for contactless IC card payment on the user side 3. It is provided collectively. The user (purchaser of the product, etc.) swipes the magnetic card, inserts the IC card, or touches the contactless IC card according to the payment method (magnetic, contact IC, contactless IC) that he / she wants to use. Perform actions such as, and make a payment.

The information processing device 1 which is an example of the present disclosure includes a screen 20 on the display surface 2 side. The clerk or the like reads the information displayed on this screen 20. Further, the screen 20 may be a touch panel type screen, and a store clerk or the like can operate the information processing device 1 via the touch panel.

The above is an example of the information processing device 1. The information processing device 1 may be an information terminal having a screen similar to the above screen 20, such as a smartphone or a tablet. The screen 20 shown in FIG. 1 is inclined with respect to the bottom surface or the like on which the information processing device 1 is placed. However, as in the case of smartphones and tablets, the screen does not have to be tilted with respect to the bottom surface or the like on which the information processing device 1 is placed. Further, the user surface 3 may have a screen similar to the screen 20 described above.

(Near the display surface 2 of the information processing device 1)
FIG. 2 is a cross-sectional view showing the vicinity of the display surface 2 of the information processing device 1. The information processing device 1 includes a chassis 10, a screen 20, a first substrate 21, a second substrate 22, and a chassis 23 housed on the back side of the chassis 10. The side of the housing 10 facing the outside of the information processing device 1 is the front side of the housing 10, and the side of the housing 10 facing the inside of the information processing device 1 is the back side of the housing 10.

The screen 20 is composed of a liquid crystal panel or the like and is arranged on the back surface side of the housing 10 to perform a display necessary for operating the information processing device 1. In order to protect the screen 20, the housing 10 may be provided with a transparent member 11 such as glass or acrylic.

The first substrate 21 may be, for example, a printed circuit board. A control device for controlling information display on the screen 20 may be mounted on the first substrate 21. In addition, components for performing various types of information processing by the information processing device 1 may be mounted on the first substrate 21. The information processing may include an authentication process and a payment process.

The second substrate 22 is a flexible printed circuit board (FPC) that is electrically bonded to the first substrate 21, and connects the first substrate 21 to the back surface side of the screen 20. In the illustrated example, the second substrate 22 connects the connecting portion 21c of the first substrate 21 and the connecting portion 20c of the screen 20. A display signal from the first substrate 21 is sent to the screen 20 via the second substrate 22, and the screen 20 displays information.

The chassis 23 is arranged between the screen 20 and the first substrate 21. The chassis 23 may be made of metal. A hole 24 is formed in the chassis 23. The second substrate 22 connects the first substrate 21 and the screen 20 via a hole 24 provided in the chassis 23. The position of the hole 24 provided in the chassis 23 is arbitrary. In the illustrated example, the hole 24 is provided at a portion overlapping the transparent member 11 along the direction L orthogonal to the surface of the screen 20. However, the hole portion 24 may be provided in a portion (for example, near the back side of the housing 10) that does not overlap with the transparent member 11 along the direction L.

The first substrate 21 includes a first contact 25 on a surface (upper surface in the drawing) on the second substrate 22 side. On the other hand, the second substrate 22 includes a second contact 26 on a surface (lower surface in the drawing) on the first substrate 21 side. Then, the first contact 25 and the second contact 26 are in contact with each other in a state of being sandwiched between the chassis 23 and the first substrate 21. The first contact 25 and the second contact 26 may be formed in a pad shape, respectively, and the contact between the first contact 25 and the second contact 26 may be surface contact or the like.

Although not shown, a first board side signal line for detecting unauthorized access is provided in the first board 21, and the first board side signal line is connected to the first contact 25. Similarly, a second board-side signal line for detecting unauthorized access is provided in the second board 22, and the second board-side signal line is connected to the second contact 26. Therefore, when the first contact 25 and the second contact 26 are in contact with each other, the signal line on the first substrate side and the signal line on the second substrate side are connected.

A cushion material 27 is provided on the side of the first substrate 21 of the chassis 23 in order to ensure the contact between the first contact 25 and the second contact 26. The cushion material 27 may be formed of, for example, a low-resilience urethane foam, but the material of the cushion material is not limited. The cushion material 27 is positioned on the side of the second substrate 22 opposite to the surface on which the second contact 26 is provided, and presses the second contact 26 against the first contact 25 side.

In the illustrated example, the first contact 25, the second contact 26, and the cushion material 27 are provided at a portion overlapping the transparent member 11 along the direction L orthogonal to the surface of the screen 20. However, from the viewpoint of preventing the occurrence of stains on the liquid crystal screen (screen 20), the first contact 25, the second contact 26, and the cushion material 27 do not overlap with the transparent member 11 along the direction L (the portion (screen 20)). For example, it may be provided near the back side of the housing 10.

(Detection of unauthorized access)
FIG. 3 is a cross-sectional view showing the vicinity of the display surface 2 of the information processing device 1 at the start of an unauthorized access act by an unauthorized access person. FIG. 4 is an enlarged view of part A of FIG.

An unauthorized accessor attempts to illegally access the inside of the information processing device 1 by cutting off the edge B (near the boundary between the screen 20 and the housing 10) of the screen 20 (see FIG. 3). Before the screen 20 is lifted by this unauthorized access, the first contact 25 and the second contact 26 are in contact with each other, and the first board side signal line and the second board side signal line are connected. (See Fig. 4). Here, the information processing apparatus 1 periodically or continuously sends an electric signal for detecting unauthorized access to the first substrate side signal line and the second substrate side signal line.

FIG. 5 is a cross-sectional view showing the vicinity of the display surface 2 of the information processing device 1 when an unauthorized access act by an unauthorized access person is detected. FIG. 6 is an enlarged view of part A of FIG.

An unauthorized access person lifts the disconnected screen 20 and attempts to illegally access the inside of the information processing device 1 (see FIG. 5). At this time, the second substrate 22 connected to the screen 20 by the connecting portion 20c is also lifted following the lifted screen 20. Then, the second contact 26 provided on the second substrate 22 is also lifted, and the second contact 26 is separated from the first contact 25. When the second contact 26 is separated from the first contact 25, the first contact 25 and the second contact 26 are not in contact with each other (see FIG. 6).

When the first contact 25 and the second contact 26 are not in contact with each other, the connection between the signal line on the first substrate side and the signal line on the second substrate side is also disconnected. Then, the above-mentioned electric signal for detecting unauthorized access does not flow to the first board side signal line and the second board side signal line. The information processing device 1 detects that the electric signal for detecting unauthorized access has stopped flowing, and disables at least a part of the functions of the information processing device 1.

The function of disabling the information processing device 1 when it detects that the electric signal for detecting unauthorized access has stopped flowing (hereinafter, "protected function") is the information processing device 1 (see FIG. 1). ) May have a payment function. The protected function (protected payment function) may include, for example, the following.
-Payment function using a magnetic card (reading information from a magnetic card using the magnetic card payment slot 4 etc.)
・ Payment function by contact type IC card (information reading from IC card by contact type IC card payment slot 5, etc.)
・ Payment function by contactless IC card (information reading from contactless IC card by touch area 6 for contactless IC card payment, etc.)
-Information reading function from the storage area included in the information processing device 1.

When the information processing device 1 detects that the electric signal for detecting unauthorized access has stopped flowing, the information processing device 1 may not be turned on. In this case, the protected functions are all the functions of the information processing device 1.

As described above, the information processing apparatus having a screen includes a first substrate, a chassis arranged between the screen and the first substrate, and a second substrate which is a flexible substrate, and the second substrate is provided. The substrate connects the first substrate and the screen through a hole provided in the chassis, and the first substrate includes a first contact on a surface on the second substrate side, and the first contact is provided. The two substrates are provided with a second contact on the surface on the first substrate side, and the first contact and the second contact come into contact with each other in a state of being sandwiched between the chassis and the first substrate. This makes it possible to provide an information processing device having a screen and having tamper resistance. Further, if the second substrate is a flexible substrate, the second substrate can be flexibly deformed. In this case, when the unauthorized accessor cuts and lifts the screen, the second substrate flexibly follows the screen, so that the members such as the first substrate and the second substrate are not destroyed. Then, since the impact and sound at the time of breaking the member are eliminated, it is difficult for the unauthorized access person to notice that the unauthorized access act is detected by the information processing device.

The chassis includes a cushioning material, which presses the second contact against the first contact side. As a result, vibration, displacement of air temperature, dimensional error, and the like can be absorbed, and the contact between the first contact and the second contact can be ensured.

If the first contact and the second contact are not in contact, at least some functions cannot be used. As a result, the information processing device can be protected from unauthorized access that disconnects the screen.

The at least a part of the functions may be a payment function. As a result, the payment function of the information processing device can be protected from unauthorized access that disconnects the screen.

Although various embodiments of the information processing apparatus according to the present disclosure have been described above with reference to the drawings, it goes without saying that the present disclosure is not limited to such examples. It is clear that a person skilled in the art can come up with various modifications, modifications, substitutions, additions, deletions, and equality within the scope of the claims. It is understood that it naturally belongs to the technical scope of the present disclosure. Further, each component in the various embodiments described above may be arbitrarily combined as long as the gist of the invention is not deviated.

The information processing apparatus of the present disclosure is useful in a field in which it is desired to ensure tamper resistance against cutting of a screen or the like.
