Hand-held computer apparatus and accessory docking thereof

摘要

A hand-held computer apparatus includes a tablet having a first connecter and an accessory docking having a second connecter for connecting to the first connecter. The second connecter has a symmetric structure, which allows the first connecter to be plugged to the second connecter in a first or a second direction. The first direction and the second direction are opposite to each other at an angle of 180 degrees. When the tablet is in a first status, in which the tablet is plugged to the accessory docking in the first direction, the tablet enters a notebook mode. When the tablet is in a second status, in which the tablet is plugged to the accessory docking in the second direction, the tablet enters a tablet mode. When the tablet is in a third status, in which the tablet is unplugged from the accessory docking, the tablet enters a regular mode.

主权项

1. A hand-held computer apparatus, comprising:
a tablet, having a first connecter; and an accessory docking, having a second connecter for connecting to the first connecter, wherein the second connecter has a symmetric structure, which allows the first connecter to be plugged to the second connecter selectively in a first direction or a second direction, wherein the first direction and the second direction are opposite to each other at an angle of 180 degree such that the front face of the tablet or the back face of the tablet is selectively facing the accessory docking, wherein when the tablet is in a first status, in which the tablet is plugged to the accessory docking in the first direction, the front face of the tablet is facing the accessory docking and the tablet enters a notebook mode; wherein when the tablet is in a second status, in which the tablet is plugged to the accessory docking in the second direction, the back face of the tablet is facing the accessory docking and the tablet enters a tablet mode; wherein when the tablet is in a third status, in which the tablet is unplugged from the accessory docking, the tablet enters a regular mode; wherein the first connecter includes a first non-inverting sense pin and a first inverting sense pin, wherein the first non-inverting sense pin is coupled to a first power terminal, a first resistor is coupled between the first non-inverting sense pin and the first power terminal, the first inverting sense pin is coupled to a second power terminal, and a second resistor is coupled between the first inverting pin and the second power terminal.
