Abstract: A vehicular information receiver is coupled to a portable device that receives information by paying a communication fee based on a unit packet fee. The receiver sets reception factors that affect the amount of data received by the portable device. An expected fee calculation unit calculates an expected communication fee based on the unit packet fee and an expected amount of data, which is based on the reception factors. A display unit displays the reception factors and the expected communication fee, which can be viewed by a user. Accordingly, the user is able to view the reception factors that determine the amount of data to be received and the expected communication fee associated with the data to be received, before such data is received from the portable device, thereby avoiding unexpected increases in communication fees.

Abstract: A medium position detection device including: a medium moving space (10) formed in which a plurality of media (30) can simultaneously move without overlapping in a predetermined direction; a light-guiding plate (11) which perpendicularly intersects the predetermined direction and defines the front of the medium moving space (10); a light source (20) disposed to emit light entering an end surface of the light-guiding plate (11); a reflecting section (13) formed in the light-guiding plate (11) so that the light having entered the light-guiding plate (11) is reflected by the reflecting section (13) and exits the light-guiding plate (11) through a back surface of the light-guiding plate (11); and detection means which detects the light from the light-guiding plate (11).

Abstract: A ball game apparatus has a plurality of balls, a spiral rail for automatically delivering the balls, a field portion on which the balls delivered by the spiral rail can roll with a given degree of freedom, winning pocket portions and invalid pockets formed over the field portion for receiving a plurality of the balls in each of them, a CCD camera for counting the number of balls received in the winning pocket portions and a calculator for calculating a score from the number of balls counted by the CCD camera.

Abstract: A shooting game machine features that movable members are hit so as to be prevented from reaching a goal, and comprises a plurality of lanes having a starting point and a turning point at both ends, a plurality of movable members moving from the starting point to the goal via the turning point. Each movable member has a hit indicator, adapted to be operated by the player, and movable member controller for returning the hit movable member to the starting point. The distance between the starting point and the turning point is gradually shortened each time the movable member reaches the turning point so as to make the shooting game more difficult.
