  • the case body 10 has a front inner wall surface 14a1 and a rear inner wall surface 14b1 as a pair of inner wall surfaces that face each other and form an upper guide slit 41 therebetween, and a pair of inner wall surfaces that form a lower guide slit 51.
  • the shutter member 30 has a first main surface 38a and a second main surface 38b as a pair of main surfaces facing the pair of inner wall surfaces, respectively. At least one of the first main surface 38a and the second main surface 38b, which is the second main surface 38b in the embodiment, has a second thick portion 39b as a thick portion extending in the sliding direction of the shutter member 30. .
  • the second thick portion 39b is provided over the entire length of the shutter member 30 in the sliding direction.
  • the second thick portion 39b is reliably arranged in the opening 42 of the upper guide slit 41 and the opening 52 of the lower guide slit 51. Moreover, since it is not necessary to partially form the second thick portion 39b in manufacturing the shutter member 30, manufacturing is easy.
  • the second thick portion 39b preferably contacts the upper inner wall surface 17b1 facing the second thick portion 39b.
  • the electronic component M is more difficult to fall into the lower guide slit 51. Further, the shutter member 30 slides while the second thick portion 39b contacts the upper inner wall surface 17b1, so that the shutter member 30 can slide smoothly.
  • the second thick portion 39b corresponds to the discharge port 19 at least in the sliding range from the state in which the shutter member 30 closes the discharge port 19 to the state in which the shutter member 30 opens the discharge port 19. It may be configured to be arranged as
  • the length of the second thick portion 39b is minimized, and material can be saved in manufacturing.
  • the shutter member 30 has a belt-like shape with a constant width, and the second thick portion 39b is provided substantially at the center of the shutter member 30 in the width direction. .
  • the second guide slit 51 is located at the center in the width direction where the gap in the front-rear direction of the opening 52 of the lower guide slit 51 is the largest.
  • the thick portion 39b can be arranged, and as a result, the effect of preventing the electronic component M from falling can be significantly obtained.
  • the shutter member 30 has an opening hole 31 for opening the discharge port 19, and the opening hole 31 partially interrupts the second thick portion 39b in the sliding direction.
  • the second thick portion 39b is formed on both the upper guide slit 41 side and the lower guide slit 51 side of the discharge port 19. are reliably arranged, and the electronic component M is prevented from falling into the upper guide slit 41 and the lower guide slit 51 .
  • FIG. 11 differs from the above-described embodiment in that the first main surface 38a of the shutter member 30 also has a thick portion, and the rest of the configuration is the same. Therefore, in the following description, the same reference numerals are given to the same components as in the above embodiment, and the description is omitted, and mainly the differences will be described.
  • the shutter member 30 of the modified example has a second thick portion 39b on the second main surface 38b and a first thick portion 39a on the first main surface 38a.
  • the first thick part 39a is a ridge protruding to the outside of the case 1. Like the second thick portion 39b, the first thick portion 39a has an isosceles triangular cross-sectional shape. The first thick portion 39a is arranged at the widthwise central portion of the shutter member 30, and has a first vertex portion 39a1 substantially at the widthwise center. The first thick portion 39 a may be provided over the entire length of the shutter member 30 . Alternatively, like the second thick part 39b shown in FIG. It may have a minimum necessary length to correspond to the opening 52 of the portion 42 and the lower guide slit 51 .
  • the first thick portion 39a is arranged in the front gap 52a between the second main surface 38b of the shutter member 30 and the lower inner wall surface 13a1.
  • the first vertex 39a1 of the first thick portion 39a may contact the groove bottom 13a4 of the lower inner wall surface 13a1.
  • the electronic component M is also prevented from falling into the lower guide slit 51 from the front gap 52a. Therefore, the electronic component M can be ejected more smoothly from the ejection port 19 .
  • the gap in the front-rear direction of the opening 52 of the lower guide slit 51 is the largest in the width direction.
  • the first thick portion 39a can be arranged in the central portion, and as a result, the effect of preventing the electronic component M from falling can be significantly obtained.
  • the cross-sectional shape of the thick portion provided on at least one of the first main surface 38a and the second main surface 38b of the shutter member 30 is not limited to a triangular shape, and may be arbitrary.
  • the number of thick portions is not limited to one as in the embodiment, and a plurality of thick portions may be provided.
