    摘要： An automatic wheel shaft reversing mechanism comprises a drive gear adapted to be rotatably driven by a driver unit; driven gears are provided which are movable in the axial direction of a wheel shaft and supported thereon, the driven gears alternatively meshing with the drive gear at right angles at two engaging portions, respectively; a cam portion is also provided which is adapted to be rotated by the driver unit to change over the engagement of the drive gear with the two engaging portions of the driven gears; a spring is also provided for biasing the driven gears. The driver unit, in preferred form, is a movement box unit. The reversing mechanism is usable in a variety of toy vehicles.

    摘要： A microcomputer comprises a timer controller for detecting a time when a disabled state in which interrupts are disabled starts and a time when the disabled state ends, a count timer which starts a counting operation when the timer controller detects a time when the disabled state starts, for measuring a period of time during which interrupts are disabled, and a comparator which receives a current count value of the count timer when the disabled state ends, and, when determining that the current count value is larger than a maximum of count values previously received which is stored in a register for storing a maximum of interrupt-disabled time periods, stores the current count value in the register.
