The linear recess 133 is provided. These recesses 133 are formed in a shape (the cross section is substantially triangular) that engages and engages with the protrusions 117 of the die 110.

  A method of placing the slider 50 separated from the belt-like plate 90 on the rotary electronic component substrate 10 installed on the terminal plate 30 using each member configured as described above will be described. First, as shown in FIG. 6, the rotary electronic component substrate 10 is placed on the terminal plate 30 connected to the terminal strip 70. At this time, the attachment portion 31 and the bent portion 33 of the terminal board 30 are inserted into the insertion hole 15 and the bent portion insertion portion 21 of the rotary electronic component substrate 10, respectively. Since the terminal strip 70 is sequentially moved in the direction of arrow A shown in FIG. 6, the rotary electronic component substrate 10 is placed as shown in FIGS. 4 and 5 by moving the terminal strip 70. The terminal board 30 can be sequentially moved to the lower side of the die 110.

  Next, in FIG. 4, the die 110 is slightly lowered (in the direction of arrow B), and the electronic component main body insertion portion 112 (see FIG. 5) below the punch insertion hole 111 provided in the die 110 is placed on the rotary electronic component substrate 10. The upper portion in the thickness direction is inserted, whereby the rotary electronic component substrate 10 and the terminal plate 30 are positioned with respect to the die 110.

  At the same time (or before and after), the belt-like plate 90 is sent (moved) in the direction of arrow C shown in FIGS. 4 and 5 directly above the die 110, so that the slider is directly above the punch insertion hole 111 of the die 110. 50 is arranged.
