Even in such a case, it is possible to individually perform an operation such as copying by performing a predetermined operation.

When the display module is set in the mobile phone, the information having the shared flag of "1" is automatically transferred from the display module to the mobile phone and stored in the RAM 214 in the mobile phone. Further, information such as the name and telephone number originally stored in the RAM 214 in the mobile phone is automatically transferred to the RAM 114 in the display module.

For example, assume that the mobile phones T1 and T2 are used by two employees belonging to the same department of a company. When the user of the mobile phone T1 sets the display module M1 on the mobile phone T1 and inputs information such as a name and a telephone number of a new customer through the operation keys 222,
The information (information related to communication) is sent from the mobile phone T1 to the display module M1 and stored in the RAM 114 in the display module M1. At that time, it is assumed that the sharing flag for the information is set to "1".

Next, the display module M1 is the mobile phone T.
When set to 2, the information whose shared flag is "1" is transferred to the RAM 214 of the mobile phone T2. After that, when the display module M2 is set in the mobile phone T2, the information is transferred from the RAM 214 of the mobile phone T2 to the RAM 114 in the display module M2. As described above, according to the present embodiment, it is possible to quickly distribute information among a plurality of mobile phones.

2.3. Connection Operation to Other Communication Devices The information sharing operation described above is not only performed between mobile phones, but can also be performed between various communication devices such as between a fixed phone and a mobile phone or between a mobile phone and a pager.

The barcode mounted on the surface of the upper door 402 and attached to the food packaging is read. In the display module 100, the food name is stored based on the read barcode, and the stock quantity of each food is stored. Reference numeral 420 denotes a warehousing button, which, when pressed by the user, increments the stock quantity of the food item related to the barcode read last by “1”. Further, reference numeral 430 denotes a delivery button, which, when pressed by the user, decrements the stock quantity of the food item related to the barcode read last by “1”.

Therefore, for example, when the user stores new food in the refrigerator 400, the bar code reader 41 is used.
It is preferable to input the food name via 0 and press the storage button 420. Further, when the food in the refrigerator 400 is consumed, the product name may be input via the barcode reader 410 and the shipping button 430 may be pressed. Accordingly, in the display module 100, the refrigerator 40 is always
The food name within 0 and the number of stocks thereof will be stored. Therefore, when the user goes out for shopping, the display module 100 may be removed from the refrigerator 400 and brought.
As a result, it is possible to clearly understand which food needs to be purchased, and to save the trouble of taking notes before shopping.

As the electronic device capable of communicating with the display module 100, various electronic devices other than the above-mentioned refrigerator can be considered. For example, when a stereo device is used as the electronic device, the display panel 120 displays the volume level, frequency characteristics, and the like.
