FIGS. 1 to 4 are drawings of a case (1) according to an embodiment. FIGS. 5 to 10 are drawings of a parts receiving device (200) according to an embodiment. The parts receiving device (200) is a device that automatically receives a plurality of parts in a case (1). First, the case (1) will be described.

Fig. 1 is a perspective view of a case (1) viewed obliquely from above. The case (1) accommodates an electronic component (50) (shown in Fig. 2) as a part therein in a separated state. The case (1) is set to be detachable from a feeder (100). Meanwhile, the feeder (100) is a device that discharges an electronic component (50) from inside the case (1) by vibrating and supplies the electronic component (50) to a mounting device (not shown). The electronic component (50) of the present embodiment is, for example, a microscopic rectangular prism-shaped electronic component whose longitudinal length is 1.2 mm or less. Examples of such electronic components include condensers and inductors, but the present embodiment is not limited thereto.

Figures 2 and 3 are perspective views showing the internal state of the case (1) from which the second member (22) described later has been removed, respectively. Figure 2 shows a state in which the discharge port (6) for discharging the electronic component (50) is open, and Figure 3 shows a state in which the discharge port (6) is closed. The discharge port (6) is an example of an opening. Figure 4 is a perspective view of the case (1) viewed obliquely from below.

The case (1) includes a case body (2), a shutter member (3), a slider (4) integral with the shutter member (3), and an RFID tag (5).

The case body (2) has a first member (21) and a second member (22). The case (1) is a container in which the first member (21) and the second member (22) are combined and joined to form an accommodation space (S) inside. The case body (2) includes a top plate portion (2U), a bottom plate portion (2D), a front wall portion (2F), a rear wall portion (2B), a right wall portion (2R) on the first member (21) side, and a left wall portion (2L) on the second member (22) side. A plurality of electronic components (50) are accommodated in a separated state inside the case (1).

Meanwhile, in this specification, the vertical direction in which the case (1) is set on the feeder (100) is referred to as the vertical direction of the case (1). In addition, in the case (1), the side where the discharge port (6) is provided is referred to as the front, and the opposite side is referred to as the rear. The left and right directions, such as left and right, are referred to as the left and right directions when the case (1) is viewed from the front. The first member (21) is on the right, and the second member (22) is on the left.

The front wall (2F), rear wall (2B), right wall (2R), and left wall (2L) are each wall sections extending vertically, i.e., in the up-down direction. The top plate (2U) and bottom plate (2D) are each board sections extending horizontally.

As shown in FIG. 1 and FIG. 4, the case (1) is configured by combining and joining a first member (21) and a second member (22) configured symmetrically left and right. That is, each of the first member (21) and the second member (22) is a half-body divided left and right.

The case body (2) has a discharge port (6) on the lower side of the front wall (2F). In the embodiment, the discharge port (6) is a square opening. Meanwhile, the discharge port (6) is not limited to a square, and may be an opening having a shape such as a circle or an oval, for example.

As shown in Fig. 2, a plate member (7) is extended between the first member (21) and the second member (22) within the receiving space (S). The upper surface of the plate member (7) is formed as an inclined surface (7a) that extends from the rear toward the lower edge (6a) of the discharge port (6) at the front, and is inclined so that the lower edge (6a) side becomes the lowest side. The inclination angle (θ) of the inclined surface (7a) is preferably 3° to 10° with respect to the horizontal direction when the case (1) is set on the feeder (100), and is more preferably 5° to 7°.

As shown in Fig. 2, a shutter member (3) for opening and closing the discharge port (6) extends continuously from the bottom plate portion (2D) to the front wall portion (2F). The shutter member (3) opens and closes the discharge port (6) by sliding along its own extension direction. The shutter member (3) extends continuously from the bottom plate portion (2D) to the front wall portion (2F) and is capable of sliding along its extension direction. The shutter member (3) is a thin and long strip-shaped film member. The shutter member (3) is made of a flexible material that has a certain degree of rigidity and is capable of bending, such as PET (Polyethylene terephthalate). The width of the shutter member (3) is slightly larger than the width of the discharge port (6), and has a width that can cover the discharge port (6) without any gaps.

The shutter member (3) has an opening (3a) at its front end that is approximately the same shape as the discharge port (6). When the opening (3a) and the discharge port (6) are aligned, the discharge port (6) is opened. When the shutter member (3) covers the discharge port (6), the discharge port (6) is closed by the shutter member (3). Meanwhile, the opening (3a) does not need to have the same shape as the discharge port (6), and may have a shape and size that open the discharge port (6).

On the upper side of the discharge port (6) in the front wall portion (2F) of the case body (2), a recessed portion (61) is provided that extends from the outside to the inside of the case body (2). On the thickness direction, i.e., the left-right side of the front wall portion (2F) of the portion where the discharge port (6) and the recessed portion (61) are provided, a pair of left-right guide grooves (62) that extend in the up-and-down direction are provided. Each of the two sides extending in the longitudinal direction of the shutter member (3) is inserted into the left-and-right guide grooves (62). The shutter member (3) is guided by the guide grooves (62) and slides up-and-down on the front wall portion (2F).

As shown in FIGS. 2 and 3, a circular hole (3b) is provided at the rear end of the shutter member (3). Using the hole (3b), a slider (4) is mounted integrally with the shutter member (3). The slider (4) is a rectangular cuboid-shaped member, and as shown in FIG. 4, has a lower opening (4c) that opens downward, and a front plate (4d) and a rear plate (4e), respectively.

As shown in FIGS. 2 and 3, the slider (4) has a flange portion (4a) extending in the left and right directions at its upper end. The slider (4) has a convex portion (4b) on its upper surface. The convex portion (4b) is fitted into a hole (3b) of the shutter member (3) and protrudes upward, thereby forming the slider (4) integral with the shutter member (3).

As shown in Fig. 4, a long concave portion (23) that is recessed upwardly in the front-back direction is provided on the bottom plate (2D) of the case (1). A slit (24) is provided on the front surface of the concave portion (23). The rear end of the shutter member (3) passes through the slit (24). The rear end of the shutter member (3) extends along the lower surface of the concave portion (23) through the slit (24). On the lower surface of the concave portion (23), a pair of recesses (26a) and recesses (26b) are provided. The convex portion (4b) of the slider (4) is capable of engaging with each of the recesses (26a) and (26b).

On the left and right sides of the bottom plate (2D) of the portion where the concave portion (23) is provided, groove portions (25) extending forward and backward are respectively provided. Left and right flange portions (4a) of the slider (4) are respectively inserted into the left and right groove portions (25). As the flange portion (4a) slides forward and backward along the groove portion (25), the slider (4) slides forward and backward. At this time, the sliding range of the slider (4) is between the position where the convex portion (4b) fits into the front pit (26a) and the position where it fits into the rear pit (26b).

As shown in Fig. 3, when the convex portion (4b) of the slider (4) is engaged with the front recess (26a), the opening (3a) of the shutter member (3) is located within the concave portion (61) and does not align with the discharge port (6). At this time, the entire discharge port (6) is closed by the shutter member (3), and the electronic component (50) is not discharged to the outside from the discharge port (6). On the other hand, when the shutter member (3) slides rearward and the convex portion (4b) is engaged with the rear recess (26b) as shown in Fig. 2, the opening (3a) of the shutter member (3) aligns with the discharge port (6). At this time, the discharge port (6) is opened, and the electronic component (50) can be discharged from the discharge port (6).

As shown in FIG. 1 and FIG. 2, the case body (2) has an upper grip portion (10A) and a rear grip portion (10B). The upper grip portion (10A) is a pair of front and rear pits provided at both front and rear ends of the upper side of the case body (2). The rear grip portion (10B) is a pair of upper and lower pits provided at both upper and lower ends of the rear side of the case body (2). Each of the upper grip portion (10A) and the rear grip portion (10B) is gripped by the robot hand, for example, when the case (1) is transported by the robot hand.

As shown in FIGS. 1 and 2, a through hole (9) penetrating left and right is provided at a position generally corresponding to the concave portion (23) at the lower portion of the case body (2). The through hole (9) is a slit-shaped hole extending in the front-back direction. An RFID tag (5) in the shape of a long strip in the front-back direction is adhered to the upper surface inside the through hole (9). The RFID tag (5) includes a known configuration having a transmitting and receiving unit, a memory, an antenna, and the like. As shown in FIG. 1, a reader/writer (105) for reading and writing information to and from the RFID tag (5) is arranged in the feeder (100).

As shown in Figures 1 to 4, the case body (2) additionally has a hook portion (8) and a T-slot portion (13) extending downward from the outer surface of the bottom plate portion (2D).

The hook portion (8) includes a front hook portion (8A) and a rear hook portion (8B). The front hook portion (8A) and the rear hook portion (8B) have the same shape, are plates extending from the top toward the bottom, having a lower end bent backward by about 90°, and having an L-shape when viewed from the side. Meanwhile, the front hook portion (8A) and the rear hook portion (8B) do not have to have the same shape.

The T-slot portion (13) includes a front T-slot portion (13A) and a rear T-slot portion (13B). Both the front T-slot portion (13A) and the rear T-slot portion (13B) are protrusions in the shape of an inverted T when viewed from the front. The front T-slot portion (13A) has a tapered portion (13c) formed at the front end with a tapered shape.

The feeder (100) has a hook portion (8) and a T-slot portion (13) that are removably fitted so that the case (1) can be set on the feeder (100), and has a non-illustrated hook portion. The hook portion (8) and the T-slot portion (13) are removably fitted to the hook portion, so that the case (1) is removably set on the feeder (100). In the case (1) set on the feeder (100) in this manner, the feeder (100) vibrates while the discharge port (6) is open, so that the electronic component (50) descends the inclined surface (7a) and is discharged from the discharge port (6). The discharged electronic component (50) is supplied to the mounting device as described above.

Next, a parts receiving device (200) according to an embodiment will be described with reference to FIGS. 5 to 10.

Fig. 5 is a plan view showing an outline of a parts receiving device (200), and Fig. 6 is a partial cross-sectional view corresponding to line VI-VI of Fig. 5.

The component receiving device (200) is a device that automatically receives a plurality of electronic components (50) in the case (1) described above through the discharge port (6) into the receiving space (S). As shown in FIGS. 5 and 6, the component receiving device (200) according to the embodiment includes a return unit (210) that returns the electronic components (50), a discharge unit (230) that drops and discharges the electronic components (50) from the return unit (210), an installation unit (240) on which the case (1) described above is installed, and a component detection unit (270).

The return unit (210) continuously returns a plurality of electronic components (50) to the discharge unit (230). The return unit (210) of the embodiment has a linear feeder (211) that continuously returns a plurality of electronic components (50) in a linear manner, and a turntable (212) that receives a plurality of components returned by the linear feeder (211) one by one and rotates the electronic components (50) by a rotational motion to intermittently return them.

A plurality of electronic components (50) are returned in a row toward a turntable (212) by a linear feeder (211) installed approximately horizontally. The linear feeder (211) vibrates, for example, by a vibrator (not shown), and the vibration sequentially returns the electronic components (50) toward the turntable (212) in the direction of an arrow (F). The electronic components (50) are returned along the linear feeder (211) while being pushed by subsequent electronic components (50). The linear feeder (211) extends toward the center of rotation of the turntable (212), and its end reaches near the outer peripheral edge of the turntable (212).

The turntable (212) is a horizontally installed disk-shaped rotating member. The turntable (212) is made of ceramic, glass epoxy resin, etc. The turntable (212) is arranged to be rotatable on a base (214) via a rotation axis (213) extending vertically. The turntable (212) intermittently rotates in the direction of the arrow (R) in FIG. 5 around the rotation axis (213) by a driving source (217) that rotates the rotation axis (213). On the outer peripheral edge of the turntable (212), a plurality of cutouts (215) opening toward the outer peripheral edge are arranged at equal intervals in the circumferential direction. One electronic component (50) is accommodated inside one cutout (215). Meanwhile, the rotation direction of the turntable (212) is not limited to the R direction in Fig. 5, and may be the reverse direction of the R direction.

As shown in Fig. 6, the turntable (212) is placed on the upper surface (216) of the base (214). The cutouts (215) are opened on the outer peripheral surface side and the upper and lower surfaces of the turntable (212). The turntable (212) includes an air suction passage (not shown) leading to each cutout (215) inside. This air suction passage is opened on the inner surface of each cutout (215). The air suction passage is connected to a suction source such as a vacuum pump, and when this suction source operates, the air inside the cutout (215) is sucked into the inner surface, thereby creating a negative pressure state. As a result, the electronic component (50) accommodated in the cutout (215) is sucked into the inner surface by the negative pressure action, and is maintained in the cutout (215).

Electronic components (50) returned to the vicinity of the turntable (212) by the linear feeder (211) are received one by one from the side in each of the plurality of cutouts (215) of the intermittently rotating turntable (212) and are held by being absorbed on the inner surface as described above. The electronic components (50) received and held in the cutouts (215) are intermittently returned to the discharge portion (230) in the direction of the arrow (R) by the rotation of the turntable (212). The electronic components (50) received in the cutouts (215) move on the upper surface (216) of the base (214).

The discharge unit (230) is arranged corresponding to the turntable (212). Specifically, the discharge unit (230) is arranged on a circular return path corresponding to the rotational trajectory of the cutout (215) of the turntable (212). The discharge unit (230) is arranged at a rotational angle position of approximately 270° with respect to the part that moves from the linear feeder (211) to the turntable (212). The discharge unit (230) is a part that drops the electronic components (50) returned by the turntable (212) one by one by their own weight into the discharge port (6) of the case (1) installed in the installation part (240).

Meanwhile, the discharge unit (230) may be placed at any position of the turntable (212), and for example, may be placed at the innermost position as viewed from the linear feeder (211), that is, at a rotation angle of 180° with respect to the portion moving from the linear feeder (211) to the turntable (212).

As shown in Fig. 7, the discharge portion (230) includes a cylindrical member (231) and a pressure pin (236). The cylindrical member (231) is an example of a guide portion. In the discharge portion (230), a passage hole (218) corresponding to a cutout (215) of the turntable (212) is provided at a portion directly below the turntable (212). The passage hole (218) has a size through which an electronic component (50) passes. In addition, the discharge portion (230) is provided with a suction release mechanism (not shown) that releases the suction and retention of the electronic component (50) by sucking air into the cutout (215). As the suction release mechanism, for example, a mechanism that blows out air to stop or weaken the flow of sucked air can be exemplified. When the turntable (212) rotates and the cutout (215) aligns with the passage hole (218), the electronic component (50) in the cutout (215) is released by the suction release mechanism, and the electronic component (50) that has moved on the upper surface (216) of the base (214) until then falls from the cutout (215) into the passage hole (218), and further falls into the interior of the cylindrical member (231) through the passage hole (218).

An electronic component (50) that falls through the passage hole (218) is guided to the discharge port (6) of the case (1) by passing through the interior of a cylindrical member (231) having a funnel shape. The cylindrical member (231) has an upper cylinder (233) in the shape of an inverted cone whose inner diameter increases as it faces upward, and a lower cylinder (234) that extends downward from the center of the lower end of the upper cylinder (233). The upper cylinder (233) and the lower cylinder (234) are integral. An electronic component (50) that passes through the passage hole (218) falls into the interior of the upper cylinder (233), reaches the interior of the lower cylinder (234), and falls through the interior of the lower cylinder (234). There are cases where the electronic component (50) slips and falls while contacting the inner surface (232) of the cylindrical member (231). The inner surface (232) of the cylindrical member (231) is an example of a sliding surface.

Meanwhile, it is preferable that the inner diameter of the upper tube (233) is larger than the longitudinal dimension of the electronic component (50), and also that the inner diameter of the lower tube (234) is larger than the longitudinal dimension of the electronic component (50) and smaller than the inner diameter of the upper tube (233).

In order to prevent the electronic component (50) from being electrically damaged by static electricity generated by friction, it is preferable that at least the inner surface (232) of the cylindrical member (231) is composed of a material including a conductive material such as a conductive metal. In addition, in order for the electronic component (50) to slide off smoothly, the inner surface (232) of the cylindrical member (231) is preferably a smooth, low-friction surface, and is preferably surface-treated with, for example, a resin such as a fluororesin.

The discharge section (230) is provided with a pressure pin (236) that forcibly drops the electronic component (50) from the cutout (215). The pressure pin (236) is an example of a pressure member that serves as a drop promoting member. The pressure pin (236) is positioned above the cutout (215) that matches the through hole (218). The pressure pin (236) is a rod-shaped member that extends vertically and is driven vertically by an actuator or the like (not shown). When the pressure pin (236) is driven downward, the electronic component (50) in the cutout (215) is pushed downward and falls into the cylindrical member (231) through the through hole (218). By being pushed by the pressure pin (236), the electronic component (50) falls reliably out of the cutout (215) without being caught in the cutout (215).

Meanwhile, as a drop accelerator replacing the pressure pin (236) or as an additional drop accelerator, an air flow generating unit (237) that causes the electronic component (50) to fall from the cutout (215) by air flow may be provided in the discharge unit (230). Examples of such an air flow generating unit (237) include one that has a function of blowing air from above to cause the electronic component (50) to fall, or drawing air from the side to cause the electronic component (50) to fall.

In addition, the discharge unit (230) is provided with a cleaning unit (238) that cleans the path of the electronic component (50) passing through the discharge unit (230). Specifically, the cleaning unit (238) is arranged above the pressure pin (236) and is configured with an air suction mechanism that sucks in air. As air is sucked in by the cleaning unit (238), the air in the path of the electronic component (50) which is the cutout (215), the passage hole (218), and the inside of the cylindrical member (231) is sucked in. As a result, debris or dust existing in the path is sucked in by the cleaning unit (238) and cleaned.

Meanwhile, the cleaning unit (238) may clean the path of the electronic component (50) by blowing away debris or dust by emitting air. In that case, in order to prevent debris or dust from entering the case (1), it may be operated with the discharge port (6) closed by the shutter member (3).

Figure 8 shows a state in which a case (1) is installed in an installation unit (240). The case (1) is installed in the installation unit (240) in a state in which the electronic component (50) discharged from the discharge unit (230) falls into the discharge port (6). The case (1) is installed in the installation unit (240) in a state in which the front-back direction of the case (1) is along the vertical direction, i.e., in a vertical state.

The installation part (240) has a wall part (241), a holding part (250) that maintains the case (1) in a vertical state on the wall part (241), and an opening/closing mechanism (260) that opens and closes the shutter member (3) of the case (1).

The wall portion (241) has a wall surface (241a) that is a surface that is approximately vertical.

The retaining member (250) includes a pair of upper and lower hooks protruding from the wall surface (241a), that is, an upper hook member (251) and a lower hook member (252). The upper hook member (251) and the lower hook member (252) have the same shape and are plates whose ends are bent upward at approximately 90° and have an L-shape when viewed from the side. As shown in Fig. 9, the front hook member (8A) of the case (1) is removably hooked from above to the upper hook member (251), and the rear hook member (8B) of the case (1) is removably hooked from above to the lower hook member (252). As a result, the case (1) is removably hooked to the retaining member (250). Meanwhile, the upper hook member (251) and the lower hook member (252) do not have to have the same shape.

A concave portion (242) extending vertically and opening toward the wall surface (241a) is formed on the wall portion (241). An opening/closing mechanism (260) for sliding a shutter member (3) is arranged within this concave portion (242). The opening/closing mechanism (260) has a driving pin (261) that is arranged to be able to move vertically along the bottom surface of the concave portion (242). The tip of the driving pin (261) protrudes from the wall surface (241a). The driving pin (261) is supported to be able to move vertically along, for example, a guide groove provided on the bottom surface of the concave portion (242), and is driven up and down reciprocally by an actuator or the like. A reader/writer (243) that is not connected to an RFID tag (5) and is capable of inputting information is arranged on the concave portion (242) of the wall portion (241).

As shown in Fig. 9, a drive pin (261) is engaged with a slider (4) of a case (1) held in a retainer (250). The shutter member (3) of the case (1) shown in Fig. 9 slides forward (upward in Fig. 9) so that a convex portion (4b) of the slider (4) is engaged with a front recess (26a), and the discharge port (6) is blocked by the shutter member (3). Meanwhile, the drive pin (261) moves upward. When the case (1) whose discharge port (6) is blocked by the shutter member (3) is held in the retainer (250) with the drive pin (261) positioned upward, the drive pin (261) is inserted into a lower opening (4c) of the slider (4) shown in Fig. 4, and is positioned between a front plate portion (4d) and a rear plate portion (4e).

From this state, when the driving pin (261) moves downward in Fig. 9, the driving pin (261) comes into contact with the rear end plate portion (4e) of the slider (4) and pushes the slider (4) downward and slides. As the slider (4) slides downward, the shutter member (3) slides rearward in the case (1). Then, as shown in Fig. 10, the convex portion (4b) of the slider (4) fits into the recess (26b) at the rear, and the opening (3a) of the shutter member (3) matches the discharge port (6) of the case (1), so that the discharge port (6) is opened. When the driving pin (261) returns upward in this state, the driving pin (261) comes into contact with the front end plate portion (4d) of the slider (4) and pushes the slider (4) upward and slides. As the slider (4) slides upward, the shutter member (3) slides forward in the case (1), and as shown in Fig. 9, the convex portion (4b) fits into the front recess (26a), and the opening (3a) is closed by the shutter member (3).

The component detection unit (270) detects the electronic component (50) at any position along the path of the electronic component (50) between the return unit (210) and the discharge port (6) of the case (1) installed in the installation unit (240). The component detection unit (270) of the embodiment includes a first component detection unit (271) arranged at a predetermined position on the side of the linear feeder (211) shown in Fig. 5, a second component detection unit (272) and a third component detection unit (273) arranged on the turntable (212), and a fourth component detection unit (274) provided on the discharge unit (230) shown in Fig. 7.

The first component detection unit (271) detects the electronic component (50) being returned by the linear feeder (211) at the correct position. The second component detection unit (272) is arranged on the upstream side of the return path of the turntable (212). The third component detection unit (273) is arranged on the downstream side of the second component detection unit (272) on the return path of the turntable (212).

Each of the first component detection unit (271), the second component detection unit (272), and the third component detection unit (273) detects arbitrary matters regarding the electronic component (50). The first component detection unit (271) has a counter function as a passage detection unit that detects, for example, that an electronic component (50) has passed and counts the number of times the electronic component (50) has passed. The second component detection unit (272) is an image sensor as a shape detection unit that detects, for example, the shape of the electronic component (50) and detects whether or not the electronic component (50) has a shape defect from the detected shape. The third component detection unit (273) functions as a performance detection unit that detects, for example, the performance detection unit. For example, when the electronic component (50) is a condenser, a capacitance sensor that detects whether or not the capacitance as a function has a specified value is applied.

The fourth component detection unit (274) includes an upstream-side passage detection unit (275) and a downstream-side passage detection unit (276) arranged at respective positions on the upstream and downstream sides of the cylindrical member (231). The upstream-side passage detection unit (275) has a counter function as a passage detection unit that counts the number of passages of electronic components (50) that pass through the passage hole (218) and enter the cylindrical member (231) upstream of the cylindrical member (231). A known optical sensor composed of a light-emitting element (275a) and a light-receiving element (275b) is used as the upstream-side passage detection unit (275). The downstream-side passage detection unit (276) has a counter function as a passage detection unit that counts the number of passages of electronic components (50) that pass through the cylindrical member (231) and enter the discharge port (6) of the case (1) downstream of the cylindrical member (231). The downstream passage detection unit (276) is similar to the upstream passage detection unit (275), and a known optical sensor composed of a light-emitting element (276a) and a light-receiving element (276b) is used. Meanwhile, the optical sensor may be a type that receives the reflection of the emitted light from the target object, and the light-emitting element and the light-receiving element may not be separated but may be formed as one piece.

According to the component receiving device (200) according to the above embodiment, the electronic component (50) is received in the case (1) as follows.

Electronic components (50) are returned one by one to the turntable (212) by the linear feeder (211). The electronic components (50) are detected by the first component detection unit (271). The first component detection unit (271) counts, for example, the number of electronic components (50) being returned. One electronic component (50) from the linear feeder (211) is received in a cutout (215) of the turntable (212) which is intermittently rotating. During the intermittent rotation of the turntable (212), the electronic component (50) in the cutout (215) is detected by the second component detection unit (272) and the third component detection unit (273).

In the second component detection unit (272), for example, the shape of the electronic component (50) is detected, and whether or not there is a shape defect in the electronic component (50) is detected from the detected shape. In the third component detection unit (273), for example, the performance of the electronic component (50) is detected. If the electronic component (50) is determined to be defective through detection by the second component detection unit (272) and the third component detection unit (273), the electronic component (50) is excluded from the turntable (212).

Electronic components (50) are returned one by one to the discharge unit (230) by the turntable (212). In the discharge unit (230), the cutout (215) is aligned with the through hole (218) and at the same time, the pressure pin (236) is lowered to push the electronic components (50) downward. The electronic components (50) fall from the cutout (215) into the through hole (218) and also enter the interior of the cylindrical member (231) through the through hole (218), fall inside the cylindrical member (231), fall from the discharge port (6) of the case (1) into the case (1), and are received. At this time, the electronic component (50) dropped from the cutout (215) is detected to enter the cylindrical member (231) by the upstream passage detection unit (275) of the fourth component detection unit (274), and the electronic component (50) dropped from the cylindrical member (231) is detected to enter the case (1) by the downstream passage detection unit (276).

The above operations are performed continuously, and a plurality of electronic components (50) are accommodated in the case (1). While the linear feeder (211) is returning the electronic components (50), the number of returned electronic components (50) is counted by the first component detection unit (271). In addition, the number of electronic components (50) that are dropped from the cutout (215) and ultimately accommodated in the case (1) is counted by the fourth component detection unit (274) including the upstream-side passage detection unit (275) and the downstream-side passage detection unit (276). When the number of electronic components (50) accommodated in the case (1) reaches a predetermined number, the return of the electronic components (50) by the return unit (210) is stopped, a new empty case (1) is replaced in the installation unit (240), and then the accommodation of the electronic components (50) into the case (1) is resumed.
