To provide a game machine which can suppress burden on a player when the player plays a game for many hours.

By one simple slide operation to slide the player's finger from a zeroth section G0 which is a reference position (reference region) in the zeroth section G0 to eighteenth section G18 in a touch sensor part 512 to be a predetermined detection region in a shooting operation device toward the eighteenth section G18 while touching, three functions, that is, starting to shoot game balls, setting the shooting strength of game balls to a game area, and stopping shooting the game balls, can be performed. Also, when the player's finger slides in the zeroth section G0 to the eighteenth section G18 in the touch sensor part 512, a repulsive force as the finger slides does not energize the player's finger, so that burden on the player's finger and wrist is reduced.
