<p>PURPOSE: To provide the portable personal computer with liquid crystal display panel in which the liquid crystal display panel is opened/closed automatically without manual operation, an opening angle fine-adjusted optimizingly is maintained and the ease of handing is considerably improved. CONSTITUTION: A motor control circuit 3 drives a motor 2 based on data in a memory circuit 4 at application of power with a switch 11 closed to open a liquid crystal display panel 1, a panel angle adjustment switch 5 is used to optimize the open angle. When the switch 11 is closed, the panel 1 is closed while counting data equivalent to the optimum angle and the data corresponding to the optimum angle are stored in the memory circuit 4 and the switch 11 is used to interrupt power.</p> |
