Mobile electronic apparatus, and battery pack for the apparatus
First Claim
1. A mobile electronic apparatus which is able to be carried by an authorized user for performing various electronic information processes, comprising:
- a main body;
a battery pack detachably attached to said main body and having an input section integrally formed with said battery pack for inputting information (data); and
a power supply terminal, adapted to be connected between said battery pack and said main body to supply electric power from said battery pack to said main body, for sending to said main body input signals relating to said information (data), which is input by said input section, whereinsaid battery pack includes a signal synthesizing circuit for carrying the input signals, which are input by said input section, onto a power supply voltage to be supplied from said battery pack to said main body, andsaid main body includes a signal separating circuit for separating and picking up said input signals carried on the power supply voltage.

Abstract
A mobile electronic apparatus in which various functions can be easily added without impairing the mobility and without making any change in the hardware. The mobile electronic apparatus is carried by its authorized user to perform various types of electrical information processing, and has an attachment part detachably attached to a main body of the apparatus for performing a predetermined function, which attachment part has an input/output section for inputting/outputting information. The apparatus also has an interface section for transferring input/output signals relating to the information between the attachment part and the main body. The invention is applicable in mobile electronic apparatus having an attachment part detachably attached thereto, internet appliances such as cell phones, mobile electronic information terminals, and PDAs.
