Passage device and medication dose management device

A passing device comprising:

• a passing operation part having a passing passage to guide movement of content;
• a passing movement part having a rotatable structure from which an opening member and a closing member protrudes in different directions from each other, rotatably disposed in the passing operation part and configured to move so that the content is passed;
• a sensing part disposed in the passing operation part and configured to sense content discharged due to free rotation of one end of the passing movement part;
• and
• a tilt sensor configured to sense a slope of the passing device,
• wherein the sensing part detects information on the sensed content, and
• wherein the sensing part includes at least one light emitter configured to emit light toward content discharged due to rotation of the passing movement part, at least one light receiver configured to receive the light emitted from the light emitter, and a sensing controller configured to sense the content discharged through the passing operation part by using the light received by the light receiver and determine that the content has been discharged by the passing movement part according to whether a slope of a container sensed by the tilt sensor is within a predetermined slope range.
