A feeder includes a housing, an ejection structure, and a driving module. The housing includes a discharge channel. The discharge channel has an accommodating space and a discharge port communicated with each other. The ejection structure includes an ejection blade. The ejection blade is rotatably disposed in the accommodating space. The driving module is configured to rotate the ejection structure, so that the ejection blade ejects the feed located in the accommodating space away from the discharge port. The driving module includes a position-returning member configured to maintain the ejection structure in a first rotational orientation relative to the housing. The driving module is further configured to rotate the ejection structure relative to the housing to exceed a second rotational orientation and then release the ejection structure.

A transmission includes a first shaft, and a second shaft, and a shifting group arranged between the first and second shafts. The shifting group is configured such that a mechanical power transmitted via the first shaft is transmitted to the second shaft via a first power path or a second power path which is coupled-in or coupled-out.
