Description

  The present invention relates to a portable communication terminal provided with an imaging means.

  Most recent mobile communication terminals are equipped with a camera as an imaging means in most models. In particular, a camera provided in a mobile phone, which is a mobile communication terminal, has a higher number of pixels year by year and a higher performance. For this reason, there is an increasing number of companies that prohibit the introduction of camera-equipped mobile phones in corporate offices, factories, or laboratories from the viewpoint of protecting personal information and maintaining confidentiality. Considering that the performance of cameras equipped in mobile phones will continue to improve in the future, it is predicted that there will be more and more places where camera mobile phones are prohibited.

  By the way, in a camera-equipped mobile phone, since the mobile phone and the camera are usually integrated, it is not possible to remove only the camera portion from the mobile phone body and store it separately. For this reason, when entering a place where the carrying of a camera-equipped mobile phone is prohibited, the mobile phone is temporarily deposited with a third party, so that there is a problem that it becomes impossible to make a phone call during that time.

  In addition, there are mobile phones in which personal information such as telephone numbers and address books are recorded, and mobile phones in which an IC chip having a cashing function using electronic money is built. When depositing such a mobile phone, it is necessary to strengthen security for preventing leakage or theft of personal information on the third party as a deposit destination.

Therefore, Patent Document 1 proposes a camera-equipped mobile phone in which only the camera portion can be removed from the mobile phone body. In this camera-equipped mobile phone, the built-in camera can be detached from the main body of the mobile phone, and a call can be made only with the main body of the mobile phone from which the camera is removed.
JP2004-122056

  However, since Patent Document 1 aims to realize a videophone using the removed camera, it is not assumed that the removed camera is entrusted to a third party. Therefore, even if the removed camera is attached to a third-party mobile phone, the camera starts without any problem. Therefore, there is a problem that personal information leaks from the memory built in the camera.

  Therefore, in the present invention, in the portable communication terminal in which the first casing having the communication means and the second casing having the imaging means are detachable, the second casing is connected to the paired first casing. Only at times is the provision of a mobile communication terminal in which the second housing functions.

  In order to achieve the above object, according to the present invention, a first casing having communication means and a second casing having imaging means are detachable, and one casing has input means for inputting information. The other housing has unique information unique to the housing, and is based on the input information from the input means and the unique information when the first housing and the second housing are connected. The determining means for determining whether to allow or reject the operation of the imaging means is provided in one of the two casings.

  According to the above configuration, the determination unit confirms the input information and the unique information, and determines whether the first housing and the second housing are a pair. As a result, when it is determined as a pair, the operation of the imaging means is permitted. When it is determined that it is not a pair, the operation of the imaging means is rejected.

  Here, when the determining unit is in one casing, the determining unit acquires unique information from the other casing. When the determining means is in the other casing, the determining means obtains input information from one casing.

  For example, when the determining means is in the first housing, a signal corresponding to the determination is output to the second housing. In the second housing, the operation of the imaging means is controlled in accordance with a signal from the first housing. When the determining unit is in the second housing, the imaging unit operates or does not operate according to the instruction of the determining unit.

  Therefore, the second housing functions when the regular second housing is connected to the first housing. However, if a non-regular second housing is connected to the first housing, the second housing does not function and unauthorized use can be prevented. As a result, leakage of information held by the portable information terminal can be prevented, and security can be improved even with a structure in which the casing can be separated.

  Specifically, the first casing includes an input unit and a determining unit, and the second casing includes a memory that stores unique information. The determining means obtains the unique information from the memory of the second casing when the first casing and the second casing are connected, and inputs the input information and the unique information input from the input means. To determine if they are related. When it is determined that the input information and the unique information are related, the operation of the imaging unit is permitted.

  Here, the unique information is information for recognizing whether the first housing and the second housing are a pair, for example, password, biological information such as vein / iris / fingerprint, portable information This is the serial number unique to the communication terminal.

  According to the above configuration, the imaging means does not operate when the second casing is connected to the third casing of the third party. Therefore, it is possible to prevent personal information stored in the second housing or captured images and videos from leaking to a third party.

  In addition, since the first casing having the communication means and the second casing having the imaging means can be separated, for example, when entering an area where imaging is prohibited, only the second casing is removed. You can deposit. Therefore, it is not necessary to leave the first housing provided with an IC chip serving as a wallet or a memory storing personal information to another person. The first housing can communicate even when the second housing is removed.

  The first housing having the communication means and the second housing having the imaging means are detachable, and a contact type or non-contact type IC chip is provided in the second housing, and the IC chip is provided in the IC chip. When specific information specific to the case is input in advance and the first case and the second case are connected, whether to permit or reject the operation of the imaging unit is determined based on the specific information. The deciding means for providing is provided in the first casing.

  With the above configuration, when the second casing is connected to the first casing, the determining unit acquires the unique information stored in the IC chip of the second casing and determines whether or not the second casing can be used. . By using the IC chip, the user can save the trouble of inputting the password, and the user does not need to always remember the password. Furthermore, it is possible to determine whether to permit or reject the operation of the image pickup means by reading the unique information stored in the IC chip, so that it is possible to prevent a third party from stealing unique information such as a password. .

  The first housing is provided with input means for inputting information and activation means for authenticating the input information from the input means and activating the imaging means when the determining means permits the operation. It is characterized by that.

  According to the above configuration, the determination unit acquires the unique information stored in the IC chip of the second casing and permits the use of the second casing. At this time, it is restricted so that the imaging means cannot be used. When information is input from the input unit, the activation unit determines whether to activate the imaging unit based on the input information. When the input information is authenticated, an activation signal is output to the imaging means to enable operation. When the authentication is not successful, the operation of the imaging means is prohibited.

  Thus, a double check can be performed to start the operation of the second housing. When a third party illegally obtains the mobile communication terminal, the input information is not authenticated and the use of the second housing can be prohibited, and the security is improved.

  In addition, when the first housing is provided with a sub display device, the second housing is provided with a main display device, and the first housing and the second housing are connected, information relating to communication Is displayed on the main display device, and when the first casing is used alone, information related to communication is displayed on the sub display device.

  According to the above configuration, even when the second housing is removed, characters and numbers input from the input unit when using a phone or mail can be displayed easily. Useful for confirmation.

  In addition, a speaker is provided in the first housing and the second housing, and when the first housing and the second housing are connected, sound is output from the speaker of the second housing, When the first casing is used alone, sound is output from a speaker of the first casing.

  According to the above configuration, sound is output from the speaker of the second housing when the second housing is connected, and sound is output from the speaker of the first housing when the second housing is removed. Is done. As a result, the second housing can be removed and a call can be made using only the first housing.

  In addition, when the first housing is provided with a power source, and the first housing and the second housing are connected, power for operating the imaging means is supplied from the power source. And

  According to the above configuration, since the second casing does not have power for operation, the function of the second casing is stopped by removing the second casing from the first casing. For this reason, the second casing cannot be used alone. For example, even when left to a third party, personal information such as a personal telephone number or address recorded on the second housing side, or an image or video captured by the imaging means may be leaked to the third party. Absent.

  The first housing is provided with a connection terminal for connecting the second housing, and the connection terminal can be connected to an external display device. According to this configuration, other large display devices can be connected, so that images, videos, characters, etc. can be seen more clearly.

  As described above, according to the present invention, when the first housing and the second housing are incorrectly connected, or the first housing and the second housing are intentionally used for the purpose of unauthorized use. When connected, the second housing is not authenticated as legitimate. Therefore, the second housing does not function and cannot be used normally. As a result, unauthorized use can be prevented and leakage of personal information and the like can be prevented.

  In addition, when entering the area where the portable communication terminal including the image pickup unit is prohibited from being brought in, the second case including the image pickup unit can be detached from the first case and deposited. Therefore, even in an area where shooting is restricted, the phone can be used only with the first housing. Furthermore, since it is not necessary to leave a part in which an IC chip that can be cashed by electronic money is stored in another person, it is also effective from the viewpoint of security.
