Description

  The present invention relates to an electronic device having an openable display device, and more particularly to an electronic device with a display device having an authentication function, a control method thereof, and a control program.

  In recent years, in-vehicle electronic devices have become more and more multifunctional, and the recording media that can be used are not only for audio such as CD and MD, but also for video such as DVD and CD-ROM. . At the same time, in-vehicle electronic devices equipped with relatively large display devices are generally used so that various displays such as navigation images, TV and DVD images, etc., can be used instead of conventional display devices that only display functions. It is becoming.

  However, there is a limit to enlargement in a limited space in the vehicle. Therefore, various ideas have been made so that a display device as large as possible can be used in a small space. For example, in the case of a device that needs to be accommodated in 180 × 50 (mm) called a 1DIN size, a device that can be accommodated in the device with the display device in a horizontal direction when not in use has been developed. Yes. This makes it possible to use a display device having a relatively large display screen without being restricted by the installation space of the device.

  By the way, in-vehicle electronic devices are expensive and are traded, so there is a high possibility of being stolen. In order to cope with this, many on-vehicle electronic devices have an anti-theft function. Anti-theft functions include, for example, software that receives authentication information called a CATS code and receives authentication, and hardware that uses a detachable panel called DCP (Detachable control panel). .

  The DCP is intended to prevent theft by removing the operation panel P from the main body S and making the main body S unusable as shown in FIGS. As shown in FIG. 9, the operation panel P is attached to the main body S by engaging engaging portions or the like provided on the operation panel P side and the main body S side. 7 to 9, D is a housed display panel.

As the anti-theft technology using DCP, those disclosed in Patent Document 1 and Patent Document 2 are disclosed.
