Description

The present invention relates to a card reader that reads data recorded on a card and records data on a card.

Conventionally, a manual card reader that reads data recorded on a card and records data on a card is known (see, for example, Patent Document 1). The card reader described in Patent Document 1 includes a card reader main body, a housing in which the card reader main body is housed, and a mounting detection mechanism for detecting that the card reader is mounted on a higher-level device. .. The card reader body includes a magnetic head and an IC contact block. A first control board to which a lead wire drawn from a magnetic head is connected and a second control board to which a cable drawn from an IC contact block is connected are attached to the card reader main body.

That is, in the card reader described in Patent Document 1, the data signal circuit of the first control board and the data signal circuit of the second control board are arranged in a protected area surrounded by a destruction detection circuit from all directions. .. Therefore, if a criminal performs some work on the card reader in an attempt to illegally acquire data from the first control board or the second control board, the destruction detection circuit will be disconnected or short-circuited, and the card reader will be affected. It is detected that some work has been done. Further, when a disconnection or short circuit of the failure detection circuit is detected, the data stored in the first control board and the second control board is erased, or the first control board and the second control board cannot be used. It is possible to prevent unauthorized acquisition of data by a criminal by executing a predetermined process such as setting.

Therefore, in the present embodiment, it is possible to detect that the front cover 11 has been removed and that the card reader 1 has been removed from the host device even when the power of the card reader 1 is turned off. Become.

In this embodiment, a switch unit 15a for detecting that the front cover 11 has been removed and a switch unit 15b for detecting that the card reader 1 has been removed from the host device are attached to the front cover 11. There is. Therefore, in the present embodiment, it is possible to collectively process the wiring of the switch unit 15a and the wiring of the switch unit 15b by using the common connection unit 15c. Therefore, in this embodiment, it is possible to simplify the wiring process of the switch portions 15a and 15b.

Even in this case, the connection portion between the protective board 14 and the control board 13 is arranged behind the switch portion 15a. Further, the connecting portion between the protective substrate 14 and the control substrate 13 is surrounded by the protective substrate 14 from both the upper and lower sides, the left and right sides, and the rear side.

In the above-described embodiment, the rear surface portion 14a, the upper surface portion 14b, the lower surface portion 14c, the right side surface portion 14d, and the left side surface portion 14e are integrated, but the rear surface portion 14a, the upper surface portion 14b, the lower surface portion 14c, the right side surface portion 14d, and the left side portion. At least one of the face portions 14e may be formed separately. In this case, at least one of the rear surface portion 14a, the upper surface portion 14b, the lower surface portion 14c, the right side surface portion 14d, and the left side surface portion 14e may be a flat plate-shaped rigid substrate. Further, when the rear surface portion 14a, the upper surface portion 14b, the lower surface portion 14c, the right side surface portion 14d and the left side surface portion 14e are all formed separately, the rear surface portion 14a, the upper surface portion 14b, the lower surface portion 14c, the right side surface portion 14d and All of the left side surface portion 14e may be a flat plate-shaped rigid substrate.

In the above-described embodiment, the seat switch having the switch portion 15a and the seat switch having the switch portion 15b may be individually provided. Further, in the above-described form, the switch portion 15a may be attached to the flange portion 6d. That is, the switch portion 15a may be attached to the main body frame 6. Further, in the above-described embodiment, the switch unit 15a, which is a contact-type detection switch having a contact electrode or the like, is a detection mechanism for detecting that the front cover 11 has been removed. It may be a mechanical switch other than the contact type detection switch, or it may be an optical sensor.

In the above-described embodiment, the breakage detection circuit formed on the protective board 14 is used to detect the disconnection and short circuit of the breakage detection circuit. However, the breakage detection circuit formed on the protective board 14 is used to detect this breakage. Only one of the disconnection or short circuit of the detection circuit may be detected. Further, in the above-described embodiment, the card reader main body 3 may not be provided with the magnetic head 7 or may not be provided with the IC contact block. Further, in the above-described embodiment, the card reader 1 is a manual card reader, but the card reader 1 may be a card transfer type card reader having a card transfer mechanism for automatically transporting the card 2.
