a rotary shaft for connecting said knob to the rotary disk and the rotary cap;
a plurality of powdered object storing apertures of different volumes penetrating vertically through a peripheral portion of the fixed cap;
a scale mark provided on the fixed cap to read a rotation position of the knob for rotation corresponding to a selected one of the plurality of storing apertures;
a powdered object taking out aperture formed in the rotary disk to overlap sequentially with the plurality of powdered object storing apertures;
a powdered object discharging aperture formed in the rotary cap to overlap with the selected one of the plurality of powdered object storing apertures and to be spaced from the powdered object taking out aperture in a circumferential direction by at least a width of the powdered object storing aperture; and
rotation range restricting means for restricting a rotation range of the rotary disk and the rotary cap with respect to the fixed cap in a range which includes at least a powdered object taking out position at which the plurality of powdered object storing apertures and the powdered object taking out aperture are overlapped with each other and a powdered object discharging position at which the powdered object discharging aperture and the plurality of powdered object storing apertures are overlapped with each other.

Abstract
A constant quantity discharging device for measuring and discharging a constant quantity of powdered object from a powdered object container includes a fixed cap, a rotary disk, and a rotary cap which are coupled and mounted to the container. The rotary disk and the rotary cap sandwiching the fixed cap are rotated manually as a unit with respect to the fixed cap. The rotary disk has a powder taking out aperture, the fixed cap has a powder storing aperture, and the rotary cap has a powder discharging aperture. The positional relationships of these apertures are shifted circumferentially as the rotary disk and the rotary cap are rotated with respect to the fixed cap such that these apertures are sequentially communicated with an adjacent aperture. As a result, the powder in the container is transferred to the powder storing aperture through the powder taking out aperture of the rotary disk, and then the powder is discharged from the powder storing aperture through the powder discharging aperture of the rotary cap. The constant quantity of powder is determined by the volume of the powder storing aperture.
