[Problem to be solved by the invention]

In the conventional electronic editing and printing system described above, the word processor or personal computer 42, the display device 3, and the electrophotographic printer 43 have a power supply of 0N10FF, and maintenance such as operations such as inserting and removing disks and replenishment of developer and printing paper is relatively short. Because the work is done periodically, a special stand or desk is required that can be arranged in a direction that is easy to operate and maintain.

However, in places such as shops and homes where space is small, or in places such as offices where there are many users of electronic editing and printing systems, it is difficult to provide a place for a dedicated desk other than the desk for processing office work. For this reason, electronic editing and printing systems are often placed on desks where office work is done, but because the word processor, electronic photo printer, and display device are large, it is necessary to work with a small desk space. It's gone.

In response to this situation, in order to miniaturize electronic editing and printing systems, miniaturization has been developed using small word processors, personal computers, flat displays such as liquid crystal displays, plasma displays and EL displays, and thermal transfer printers. However, there are problems with small word processors and personal computers having slow processing speeds, and thermal transfer printers with poor print quality.
