Electronic system having portable electronic apparatus and external expansion unit for expanding function of electronic apparatus
First Claim
1. An electronic system comprising:
- an electronic apparatus body having a bottom surface and a rear surface continuous with the bottom surface, and having a first connector arranged on the rear surface;
an external expansion unit having a first surface opposing the bottom surface of said electronic apparatus body, and a second surface opposing the rear surface of said electronic apparatus body, said electronic apparatus body being detachably coupled to said external expansion unit, said external expansion unit having a second connector on the second surface, and said second connector being detachably connected to said first connector;
engaging means arranged on the first surface of said external expansion unit, said engaging means being movable between a first position where said engaging means is separated from the bottom surface of said electronic apparatus body and a second position where said engaging means is engaged with the bottom surface of said electronic apparatus body to pull said electronic apparatus body toward the second surface; and
an operation mechanism for selectively moving said engaging means to the first and second positions, said operation mechanism connecting said first connector to said second connector upon moving said engaging means to the second position.

Abstract
An electronic system includes an electronic apparatus body and an external expansion unit. The electronic apparatus body has a bottom surface and a rear surface. A first connector is arranged on the rear surface. The external expansion unit has a first surface opposing the bottom surface, and a second surface opposing the rear surface. The external expansion unit has a second connector which is detachably connected to the first connector. The external expansion unit has an engaging device. The engaging device is movable between the first position where the engaging device is separated from the bottom surface and the second position where the engaging device is engaged with the bottom surface to pull the electronic apparatus body toward the second surface. The external expansion unit has an operation mechanism for selectively moving the engaging device to the first and second positions.
