1. A dice displaying apparatus for a computer game machine comprising:
- a trackball for controlling die means;
detecting means for detecting an amount and direction of operation of said trackball;
display position operating means for deriving a rolling angle and rolling speed of said die means from said amount and direction of operation detected by said detecting means, and determining a die display position from said rolling angle and said rolling speed every predetermined interval of time;
image memory means for storing image patterns of each side of said die means expressing varied phases of rolling movement thereof at a plurality of rolling angles;
display control means for selectively reading said image patterns of said varied phases of rolling movement from said image memory means based on said rolling angle derived by said display position operating means, and outputting an image pattern selected to said die display position; and
display means for displaying said image patterns of said die means.

Abstract
A dice displaying apparatus for a computer game machine includes a trackball operable by each player. Rolling speeds of two dice are derived from an amount and direction of operation of the trackball. Rolling angles of the dice are also derived from the amount and direction of operation of the trackball, with slight angles derived from random numbers added thereto. Display positions for the respective dice are determined every predetermined intervals of time from the rolling speeds and rolling angles. Image patterns of varied phases of rolling dice corresponding to the rolling angles are presented in the respective display positions on CRT displays.
