Abstract: The present invention relates to a disc package having a structure in which a cover can be fixed on a base by simply pressurizing the cover with respect to the base in a base shaft axial direction and, at the same time, the cover can be prevented from being accidentally separated from the base while the disc package is being transported. Further, in the disc package, a cover once fixed on a base can be separated therefrom by rotating the cover along the circumference of the base in any direction, i.e., in either a clockwise or a counterclockwise direction. Furthermore, an end portion of a shaft can be fitted into a concave portion of a cover even in case the end portion of the shaft is not aligned with the concave portion of the cover.

Abstract: An electronic component feeding apparatus conveys chip components intermittently by moving a belt. This apparatus has a motion changing mechanism for changing an input motion for moving the belt to an unequal speed motion having a low initial speed and for transmitting the changed unequal speed motion to a belt moving mechanism. This motion changing mechanism has a cam member having a cam face of a predetermined shape and a cam contact member in contact with the cam face, and performs the motion change by a relative movement between the cam member and the cam contact member. An unequal speed motion (accelerated motion) after being changed by the motion changing mechanism is transmitted to the belt moving mechanism, whereby an initial speed when the belt is moved is decreased.

Abstract: An electronic component feeding apparatus for separating a foremost electronic component conveyed to a predetermined takeout position from a succeeding electronic component, wherein, the separating device includes a first component stopper, a second component stopper projecting from the first component stopper and having a magnetic attractive force at a tip end thereof for separating a foremost electronic component. The second component stopper is movable within the first component stopper between a retracted and a protruding position so that the foremost electronic component engages both the first and second component stoppers during separation from a succeeding electronic component.
