PURPOSE: To attain usefulness for improving the athletic ability of an infant while enjoying a video game, etc., by providing a first pulse string generating means generating a horizontal axis movement pulse string in accordance with handle rotation and the second pulse string generating means generating a vertical axis movement pulse string in accordance with operation lever rotation. CONSTITUTION: When the infant rotates a handle, a horizontal axis detecting part X rotates a disk X' which is provided at one end with multiple windows in accordance with handle rotation. Then, light emitted from a light emitting diode LED 310 constituting a first photocoupler, which is arranged in the neighborhood of the disk X', is made to pass by the open/close of the multiple windows and an optical signal corresponding to it is received by an optical sensor 311 so that the pulse string X1 corresponding to the rotation of the disk X' is supplied to an ADB transceiver 220. When the infant moves the operation lever in a front/rear direction in the same way, the vertical axis detecting part Y rotates the disk Y' which is provided at one end with the multiple windows in accordance with operation lever rotation. |
