2. Description of the Related Art In recent years, with the development of information technology, various types of media data have been generally communicated, and accordingly, not only audio information but also various types of images, texts, and the like have been transmitted to mobile phones. A function for communicating media data is added. For example, a mobile phone having a text mail function has been put into practical use. A text mail of text data can be created by inputting a button key of the telephone, and the text mail can be wirelessly transmitted to a designated mobile phone of the other party. It has become. Further, as called a mobile tool, a portable telephone is connected to a personal computer, and is used as a communication device for wirelessly communicating various media data created by the personal computer.

Recently, a portable telephone has been developed in which a small camera such as a CCD is provided integrally or in a cord connection, and which can wirelessly transmit image data taken by the small camera to a designated portable telephone. ing.
Such data such as texts and images are stored and held in a memory built in the mobile phone, and can be displayed on a display screen such as an LCD provided in the mobile phone and presented to the user, and can be presented to the user. Then, the transmission contents can be confirmed, and the reception side can confirm the reception contents.

However, since a portable telephone is required to be reduced in size and weight in order to improve its portability, there is a limit in increasing a display screen for outputting data such as texts and images. For this reason, full text cannot be displayed in long text data, and large data cannot be displayed in image data, which hinders the user from reading the data. Occurs. Such a situation becomes more remarkable as the communication of relatively long text data and the communication of image data become generalized, and becomes a serious obstacle in promoting multimedia communication using a mobile phone.

It is bulky and bulky, which greatly impairs portability. Further, for example, if the user tries to view image data as a large image, the location where the mobile phone is used is restricted by the installation location of the printer device, so data communication can be performed anywhere regardless of location, and the user can view the data. This greatly impairs the convenience of a mobile phone that can be used.

The present invention has been made in view of the above circumstances, and uses a charger that is always attached to a mobile phone to charge the battery without impairing the portability and usability of the mobile phone. It is another object of the present invention to simply print out image data and the like output from a mobile phone. Further objects of the present invention will be apparent in the following description.
