Abstract
A component feeding device transports a tape (a component feeding tape) in which electronic components are stored with some transportation device, and exposes the components. Transportation of the component feeding tape may be performed by fitting a sprocket with a feed hole of the component feeding tape. It has been found that sprocket does not necessarily fit with the feed hole of the component feeding tape. It has been found that this phenomenon takes place in a case of driving at least two or more sprockets with a driving device. When the sprocket does not fit with the feed hole, transportation of the tape is not correctly performed, but exerts an undesirable influence such as reduction of mounting efficiency on feeding of the components and subsequent mounting of the components. One feature resides in rendering a backlash of an upstream-side sprocket larger than a backlash of a downstream-side sprocket.
