Abstract: PROBLEM TO BE SOLVED: To secure a desired range of observation angles while keeping high brightness by bringing into a specific range the diffusion coefficient of a light diffusing element disposed on a light emitting surface of a light deflecting element disposed on a light outgoing surface of a light guide body. SOLUTION: A light deflecting element 4 is disposed on a light outgoing surface 23 of a light guide body 3 and efficiently deflects, in an objective direction, outgoing light having distribution suitably formed by the light guide body 3. A light diffusing element 5 is disposed on a light emitting surface 42 of the light deflecting element 4 and its principal plane is positioned parallel to an X-Y plane. The light diffusing element 5, as a surface light source element, needs to have an ability to improve the distribution of the outgoing light while preventing brightness from lowering to secure an appropriate range of observation angles.  With this aim, the light diffusing element 5 used has a diffusion coefficient of 5 to 10% relative to the outgoing light from the light deflecting element 4 in an X-Z plane normal both to the light incoming surface 21 of the light guide body 3 and to a light outgoing surface 23 thereof. Preferably, the light diffusing element 5 has a transmission coefficient of 65% or more relative to all the rays of light.

Title: Game machine and recording medium
Inventor: KANAZAWA HIROSHI
IPC: A63F7/02
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To realize a game machine which can heighten dispensing efficiency of premium media. SOLUTION: When a sub-CPU judges that a premium winning number Un to a paying-out number '5' other than the maximum paying-out number '15' is stored in a memory (S30: Yes), the sub-CPU reads out the paying-out number '5' corresponding to the premium winning number Un from a premium winning number table (S32), and calculates the integrated value An of paying-out number '5' (S34). Then, the sub-CPU adds '1' to the integrated value a of the paying- out number '5' (S36). When the resulting integrated value a is judged as 3 (a1) (S38: Yes), the integrated value 5*3=15 (An) is judged higher than the maximum paying-out number '15' (S40: Yes).  When the integrated value '15' is judged to be equal to the maximum paying-out number '15' (S42: Yes), the premium winning number (3) corresponding to the paying-out number '5' read out at S32 is subtracted (S44) and '1' is added to the premium winning number Um of the maximum paying-out number '15' (S46). Thus 3 cycles of paying-out 5 is reduced to 1 cycle of paying-out 15.
