A processing apparatus that can accept logs from external processing apparatuses efficiently without degrading the performance of its own. A clearance-recovery wedge-like coupling is included at the upper stop and in the slider, which includes respective tilted sections and opposite tilted sections to make, upon engagement of the upper stop and slider, a clearance-recovery taper fit. The game follows the general rules of putt-putt golf, except for the rule that the player must not touch the club with their hands when swinging.
