Whether or not a lead wire has been normally cut and clinched can be reliably detected. A contact pipe is arranged in lead wire insertion holes of a pair of fixed pawls in a state of being electrically insulated from the fixed pawls. In a case where the lead wire is shorter than a set length after the lead wire is inserted into the lead wire insertion holes, a clearance of the pair of lead wire insertion holes is widened by a set amount in the event of outward bending of the lead wire and is narrowed by a set amount in the event of inward bending. A cut-and-clinch operation is performed with S4 bypassed in a case where the length of the lead wire is at least the set length.

There is provided a tape feeder for supplying, using a taped electric component including a carrier tape and multiple electric components held onto the carrier tape, the electric component in a supply position, the tape feeder including a detection sensor configured to detect presence or absence of the electric component in the supply position.

The positional accuracy of a pair of movable elements that are made to approach each other and separate from each other is improved by one driving source. The relationships between setting pitches, pitch deviation amounts, axis deviation angles, and central point deviation amounts of the pair of movable elements are stored as a deviation table. On the basis of the deviation table and a target pitch determined by the spacing between lead wires of a lead component to be inserted into a board, a pitch deviation amount, an axis deviation amount, and a central point deviation amount for the target pitch are acquired by an interpolation method (S25). Control instruction values to an x-axis motor, a y-axis motor, a motor, and a P motor are created taking into consideration correction values corresponding to these deviation amounts, and control is performed accordingly (S26 to S28). As a result, it is possible to accurately control the positions of the pair of movable elements, and it is possible to perform control such that lead wire insertion holes reach positions facing through-holes provided in the board. Therefore, the lead wires of the lead component are favorably inserted into the lead wire insertion holes, and it is possible to favorably perform cutting and clinching.

A lead component mounting machine is provided in which lead wires are pinched and held from both sides by a pair of pawl portions, and the lead wires are inserted into through-holes of a board. The holding by the pawl portions is loosened, and a component main body is pushed in by a pushing-in device until the component main body comes into contact with the pawl portions. Subsequently, the strength of the holding by the pawl portions is increased, and the cutting and clinching of the lead wires is performed. Sliding movement of the lead wires is in a state of being suppressed by the pawl portions.
