PURPOSE:To obtain correctly elapsedly the number of times and the quantity of dung, the number of times of urination and the component quantity in the urine by dropping the dung and the urine, onto the winding paper, which the experiment animal in the cage discharges, and winding them for constant time each. CONSTITUTION:A rubber belt 14 is shifted, protrusions 15 and 16 are shifted and the one side is engaged to a limit switch 17. When the limit switch 17 is operated, a motor 9 is stopped and a timer 10 is started. Namely, for the constant time set by the timer 10, the motor 9 is stopped, the winding of paper is stopped, the motor 9 is started again after the constant time, the next protrusion is engaged to the limit switch 17, and until then, the winding is executed. Consequently, when the interval of the protrusions 15 and 16 is the length or above of a cage 2, the paper surface of the new winding paper can be developed at the lower surface of the cage 2 for the constant time. |
