(In actuality, this number is limited to one by one in combination with the alignment effect by the notch groove 22 described above.) As will be described later, the concave portion 1 Oa of the vibrating bowl 10 is exposed to the outside within a predetermined time. The total number force of the discharged metal balls 15 can be accurately estimated by the first optical sensor 16a.
- the metal sphere 15 existing near the end of the conveyance path 20 is moved in a direction substantially perpendicular to the conveyance direction of the metal sphere 15 in the conveyance path 20 and A step portion 26 that can be discharged to the outside of the recess 10 a along the obliquely downward direction is provided at the end of the transport path 20.

- the guide member 12 is connected so as to be integrated with the vibration bowl 10 by appropriate fixing means (not shown), and vibrates with the vibration of the vibration bowl 10. is there.
- the guide member 12 plays a role of guiding the metal ball 15 after passing through the notch slope 26a to the chute 32 (see Fig. 6), and following the lower end of the notch slope 26a, The slope has the same angle as the tilt angle. As a result, the metal ball 15 about to pass through the notched slope 26a can move smoothly from the notched slope 26a toward the chute 32.
- the width d of the notched slope 26a is adjusted to be more than 1 time the diameter of the metal ball 15 and less than 2 times its diameter. In this way, it is possible to avoid a defective product or a long thin impurity of the metal ball 15 that is longer than the width d of the cut-out slope 26a and connected in series with each other from entering the discharge path of the metal ball 15.
- the reflection type first optical sensor 16a described above is unloaded from the conveyance path 20, and the number of the metal balls 15 in the middle of conveyance in the step section 26. It is arranged so that it can be counted. That is, the detection window of the first optical sensor 16a faces the notched slope 26a.
- the upper arrangement limit of the first optical sensor 16a is directly above the position corresponding to the position of the notched slope 26a on the extension line of the metal ball 15 in the vicinity of the end of the transfer path 20 in the transfer direction. More preferably, the force on the extension line in the conveying direction is equivalent to one metal ball 15, a notched slope 26. It is directly above the position shifted downward along a. In this way, the first optical sensor 16a can detect the metal sphere 15 having the minimum velocity component along the inclination of the cut-out slope 26a, and the first optical sensor 16a does not successfully eject the force to the cut-out slope 26a. It is preferable that the metal ball 15 is erroneously detected.
- the downward placement limit of the first optical sensor 16a is the same as the time when the preceding metal ball 15 is discharged to the notched slope 26a, and the time when the subsequent metal ball 15 is discharged to the notched slope 26a.
- the starting metal ball 15 is directly above the position where the notched slope 26a (or the guide member 12) has moved.
- the subsequent metal ball 15 is not discharged continuously from the cut-out slope 26a until the first metal ball 15 is detected by the first optical sensor 16a.
- the total number of the metal balls 15 discharged from the recess 10a to the outside can be made equal to the total number of the metal balls 15 based on the number data obtained by the first optical sensor 16a. No number shift occurs.
- the detection window force of the first optical sensor 16a is arranged opposite to the notched slope 26a so that interference with other members can be appropriately avoided, so that the first optical sensor 16a Maintenance such as attachment and detachment is also improved.
- step portion 26 when the metal ball 15 is discharged from the recess 10a to the outside, an orthogonal discharge technology perpendicular to the transfer direction of the metal ball 15 near the end of the transfer path 20 is realized. Is done.
- the transport direction of the metal balls 15 can be changed to a substantially right angle by the step part 26. Due to such a change in the conveying direction, an appropriate separation is ensured between the metal balls 16 flowing through the step portion 26.
- the first optical sensor 16a can be reliably detected.
- the transfer speed of the metal ball 15 in the step portion 26 is the inclination angle of the notched inclined surface 26a inclined downward. And the number of metal balls 15 passing through the step portion 26 per unit time is facilitated. Further, according to the first optical sensor 16a, it is possible to accurately count the number of metal balls 15 discharged from the concave portion 10a of the vibration bowl 10 to the outside.
- the arrangement position of the first optical sensor 16a is more directly above the position of the notched slope 26 on the extension line in the conveyance direction of the metal ball 15 existing near the end of the conveyance path 20. Desirably, it is directly above the position of the notched slope 26a shifted downward by one metal ball 15 from the extended line in the transport direction, and the total number of metal balls 15 discharged from the recess 10a to the outside, It is preferable that the number deviation does not occur between the total number of the metal balls 15 based on the number data obtained by one optical sensor 16a.
- the assembly of the metal balls 15 near the terminal end of the conveyance path 20 is easily arranged in a row and in one row due to the arrangement effect of the notch groove 22 and the piece member 23 described above.
- the metal balls 15 are discharged one by one to the detection window area of the first optical sensor 16a. Therefore, based on the arrangement effect of the notch groove 22 and the piece member 23, the first optical sensor 16a does not generate a number detection error for the metal ball 15 discharged to the outside from the recess 10a. The number of metal balls 15 can be reliably detected.
- a metal sphere 15 discharged from the vibrating bowl feeder 50 is used as a deposition film forming substrate.
- the configuration of the vacuum deposition apparatus for depositing a film on the surface and the vacuum deposition operation will be described.
- FIG. 6 is a schematic diagram showing a schematic configuration inside the vacuum evaporation apparatus according to the embodiment of the present invention.

- Turrets 33, and four container 31 such as a resistance heating boat, which are arranged on the turret 33 at intervals of about 90 ° in the circumferential direction of the turret 33 and correspond to the final supply destination of the metal balls 15.
- one vibrating bowl feeder 50 arranged at a suitable position inside the vacuum chamber 30, and the vibrating bowl 10 of the vibrating bowl feeder 50 (the concave portion 10a of the vibrating bowl 10) from the guide member 12 is used to heat and evaporate the metal ball 15 filled in the container 31 at the vapor deposition site 34.
- heating means for example, resistance heating type heating means via a boat as the container 31; not shown.
- the heating means described here is not limited to resistance heating, but may be, for example, electron beam heating.
- the vibration of the vibrating bowl 10 causes the coil 10 to spiral up along the conveying path 20 (Fig. 2) on the inner wall of the recess 10a, and by the notch groove 22 (Fig. 3) and the single member 23 (Fig. 4).
- One row of the metal balls 15 arranged in a row is detected by the first optical sensor 16a while moving along the notched slope 26a (Fig. 5) of the step portion 20 at the end of the conveyance path 20. It is discharged outside.
- the metal balls 15 discharged to the outside of the recess 10a are moved one by one through the guide member 12 and the chute 32, and are filled into one container 31.
