FIG. 10 is an illustrative view showing one example of a conventional electronic component chip storage cassette. The electronic component chip storage cassette 1 includes a case 2. In the case 2, a storage portion 3 for storing an electronic component chip is formed. Continuing from the storage portion 3, the case 2 is formed with a discharge port 4 for discharging the electronic component chip to the outside. A slide groove 6 for sliding the knob 5 is formed on the side surface of the case 2, and a thin shutter 7 fixed to the knob 5 is slidably attached. The shutter 7 is guided from the side surface of the case 2 so as to cross the discharge port 4, and the discharge port 4 is opened and closed by the shutter 7 by sliding the knob 5.
[0003]
An electronic component chip is accommodated in the accommodating portion 3 of the case 2 and transferred to the user in a state where the discharge port 4 is closed by the shutter 7. A user mounts an electronic component chip on a circuit board or the like by a mounting machine.

Then, the electronic component chip is supplied from the supply machine to the mounting machine, and the electronic component chip is mounted on the circuit board by the mounting machine.
[0004]
[Problems to be solved by the invention]
However, in such an electronic component chip storage cassette, the shutter cannot be fixed so as not to slide, and the electronic component chip may leak during transportation. Also, it is difficult to confirm whether the shutter is completely closed. Furthermore, in order to supply the electronic component chip to the mounting machine, the electronic component chip is inserted into the receiving portion of the supply machine. However, since the shutter opens easily, if the electronic component chip storage cassette is set in the supply machine by mistake, the characteristics There is a risk of mixing different chip parts.
On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 8-167772, a shutter is provided with a convex portion, and a concave portion corresponding to the convex portion is provided in the case so that the shutter can be easily engaged. Electronic component chip storage cassettes are known. However, in Japanese Patent Application Laid-Open No. Hei 8-167792, since the convex portion of the shutter and the concave portion of the case are present inside the case, it has not been possible to visually check whether or not they are engaged. Therefore, there is a possibility that the convex part of the shutter and the concave part of the case are handled in a state where they are not completely engaged. In this case, there is a problem similar to that of the conventional electronic component chip storage cassette shown in FIG. Yes.
[0005]
Therefore, the main object of the present invention is to reliably fix the shutter in the closed state, to confirm that the shutter is in the closed state, and to cope with prevention of erroneous insertion of chip parts. An electronic component chip storage cassette is provided.
[0006]
[Means for Solving the Problems]
The present invention relates to a case having a storage portion for storing a plurality of electronic component chips and a discharge port for discharging the electronic component chips from the storage portion, a shutter for opening and closing the discharge port, and the shutter as a discharge port. The electronic component chip storage cassette includes a stopper for stopping the movement of the shutter in a closed state and a display means for displaying that the discharge port is closed.
In such an electronic component chip storage cassette, a stopper is formed by a rotating body having a protrusion on the outer peripheral surface, and a hole for inserting the protrusion is formed in the shutter, and the stopper is rotated to protrude into the hole. The display unit may be formed by switching between a movable state and a stopped state of the shutter by inserting and removing the portion, and indicating the rotation angle of the stopper.
Also, a stopper is formed with a rod-shaped fastener, and a hole for inserting the fastener into the shutter is formed, and the shutter is stopped by inserting the fastener into the hole and fixing it to the case, and whether there is a stopper Display means may be formed by
Furthermore, a stopper is formed with a long knob formed to be rotatable on the shutter, and a slide groove for sliding the knob on the case and a hole larger than the width of the slide groove continuous with the slide groove are formed, The shutter may be stopped by rotating the stopper so that the longitudinal direction of the stopper faces the width direction of the slide groove at the hole portion, and the display means may be formed by the direction of the stopper.
[0007]
Since the movement of the shutter is stopped by the stopper with the case outlet closed, it is possible to prevent the electronic component chip stored in the storage portion from leaking during transportation. Further, since there is a display means for displaying that the discharge port is closed, it can be confirmed that the shutter is completely closed. Furthermore, by introducing a mechanism for removing the stopper after confirming the type of the electronic component chip to the feeder for inserting the electronic component chip, erroneous insertion of the electronic component chip can be prevented.
By adopting a rotating body having a protrusion on the outer periphery as a stopper and inserting the protrusion into a hole formed in the shutter, the movement of the shutter can be stopped. Then, the movable state and the stopped state of the shutter are switched by rotating the stopper. At this time, it is possible to confirm whether the shutter is in a movable state or a stopped state by indicating the rotation angle of the stopper.
In addition, a rod-like fastener can be employed as the stopper, and in this case, the movement of the shutter can be stopped by inserting the fastener into a hole formed in the shutter and fixing it to the case. At this time, the presence of the fastener makes it possible to confirm that the shutter is in a stopped state.
Furthermore, a long knob formed rotatably on the shutter can be adopted as a stopper, and in this case, the shutter can be opened and closed by sliding the slide groove of the case. Then, the knob is brought to the position of the hole with the shutter closed, and the knob is rotated at the position of the hole larger than the width of the slide groove so that the longitudinal direction of the knob faces the width direction of the slide groove. It becomes impossible to slide in the slide groove, and the movement of the shutter is stopped. Therefore, whether the shutter is in a movable state or a stopped state can be confirmed by the direction of the knob.
[0008]
The above object, other objects, features, and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention with reference to the drawings.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is an illustrative view showing one example of an electronic component chip storage cassette of the present invention. The electronic component chip storage cassette 10 includes a case 12. A housing portion 14 for housing the electronic component chip is formed in the case 12. Furthermore, a discharge port 16 for discharging the electronic component chip stored in the storage unit 14 is formed at one end of the case 12 continuously to the storage unit 14.
[0010]
A slide groove 20 for sliding the knob 18 is formed on the side surface of the case 12. The knob 18 is attached to a thin plate-like shutter 22, and the shutter 22 can be slid along the slide groove 20 by sliding the knob 18 in the slide groove 20.
[0011]
Further, in the vicinity of the discharge port 16, a direction changing portion 24 in which the inside of the case 12 is formed in a substantially arc shape is formed. When the shutter 22 is guided to the direction conversion unit 24, the direction of the shutter 22 is converted to a direction crossing the discharge port 16. Further, shutter holding portions 26 and 28 are formed at both ends of the discharge port 16. The shutter holding portions 26 and 28 are formed to face each other and are formed as a gap through which the shutter 22 passes. By inserting the shutter 22 into the shutter holding portions 26 and 28, the shutter 22 can be stably held in a state where the discharge port 16 is closed.
[0012]
Further, as shown in FIG. 2, a stopper 30 is formed in front of the direction changing portion 24. The stopper 30 is formed in a columnar shape, and as shown in FIG. 3, the convex portions 30 a and 30 b formed in the vertical direction are rotatably held by the case 12. One convex portion 30 a is held so as to be exposed to the outside of the case 12. Then, a driver groove 32 for applying, for example, a minus driver is formed on the surface of the convex portion 30a. Therefore, the stopper 30 can be rotated by rotating the driver groove 32 against the driver.
[0013]
A protrusion 34 is formed on the outer peripheral surface of the stopper 30. The protrusion 34 is for stopping the movement of the shutter 22, and as shown in FIG. 4, a hole 36 through which the protrusion 34 passes is formed in the shutter 22. The hole 36 is formed so as to be positioned at the protrusion 34 forming portion when the shutter 22 is in a state where the discharge port 16 of the case 12 is closed. As shown by the arrow in FIG. 4, the protrusion 34 can be directed to the shutter 22 side or removed from the shutter 22 side by rotating the stopper 30. At this time, the orientation of the protrusion 34 can be displayed according to the orientation of the driver groove 32.
[0014]
In such an electronic component chip storage cassette 10, as shown by a straight arrow in FIG. 2, the discharge port 16 of the case 12 is closed by a shutter 22, and as shown by an arcuate arrow in FIG. , The protrusion 34 is inserted into the hole 36 of the shutter 22, and the movement of the shutter 22 is stopped. Further, by rotating the stopper 30 and removing the protrusion 34 from the hole 36 of the shutter 22, the shutter 22 can slide, and the discharge port 16 can be opened to discharge the internal electronic component chip.
[0015]
At this time, the display part 38 may be formed in the case 12 so as to indicate the direction of the driver groove 32 of the stopper 30. For example, characters such as “LOCK” are formed at the position indicated by the driver groove 32 when the stopper 30 is inserted into the hole 36 of the shutter 22, and the driver is operated when the stopper 30 is out of the hole 36 of the shutter 22. It is conceivable to form a character such as “RELEASE” at the position indicated by the groove 32. Such characters are not necessarily formed, and only the direction of the driver groove 32 functions sufficiently as display means for indicating whether the shutter 22 is movable or stopped.
[0016]
In the electronic component chip storage cassette 10, the movement of the shutter 22 can be reliably stopped with the shutter 22 closing the discharge port 16 of the case 12. Therefore, it is possible to prevent the electronic component chips stored in the storage unit 14 from leaking during transportation. Further, whether the shutter 22 is in a movable state or a stopped state can be confirmed by the direction of the driver groove 32 of the stopper 30, so that it can be known that the discharge port 16 is in a closed state.
[0017]
Further, when mounting the electronic component chip storage cassette 10 on a circuit board or the like, the electronic component chip storage cassette 10 is mounted on a feeder for supplying the electronic component chips. At this time, after confirming the type of the electronic component chip, by introducing a mechanism for rotating the stopper 30 into the feeder, it is possible to prevent the electronic component chip having different characteristics from being erroneously inserted.
[0018]
Further, as shown in FIGS. 5 and 6, a pin-like fastener 40 may be used as a stopper. In this case, a bush 42 for fixing the stopper 40 to the case 12 is formed. Then, with the discharge port 16 closed by the shutter 22, the movement of the shutter 22 can be stopped by inserting the hole 36 of the shutter 22 and fixing the fastener 40 to the bush 42. At this time, it is possible to know whether the shutter 22 is in a movable state or a stopped state based on the presence or absence of the fastener 40.
[0019]
Further, as shown in FIG. 7, a knob 44 used as a stopper can be attached to the shutter 22. A driver groove 46 is formed at the center of the knob 44, and the knob 44 is rotatably attached to the shutter 22. The knob 44 is held so that it can slide in the slide groove 20 formed in the case 12.
[0020]
As shown in FIGS. 8A and 8B, the knob 44 has a substantially arc-shaped convex portion 48 with the driver groove 46 as the center. The width of the slide groove 20 formed in the case 12 is formed to be substantially the same as the width of the knob 44, and the inside of the slide groove 20 is set in a state where the width direction of the knob 44 matches the width direction of the slide groove 20. Can slide.
[0021]
Further, a circular rotation hole 50 having a diameter larger than the width of the slide groove 20 is formed on one end side of the slide groove 20. The inner diameter of the rotation hole 50 is formed so as to substantially coincide with the outer diameter of the convex portion 48 formed on the knob 44. Therefore, the knob 44 can be rotated in the rotation hole 50. The rotation hole 50 is formed in a portion where the knob 44 is located when the shutter 22 is in a state where the discharge port 16 of the case 12 is closed.
[0022]
In such an electronic component chip storage cassette 10, the discharge port 16 can be opened and closed by the shutter 22 by sliding the knob 44 in the slide groove 20. Then, by rotating the knob 44 in the rotation hole 50 with the shutter 22 closing the discharge port 16 of the case 12, the longitudinal direction of the knob 44 is set in the width direction of the slide groove 20 as shown in FIG. 9. Can match. With this state, the knob 44 can no longer slide in the slide groove 20, and the movement of the shutter 22 is stopped.
[0023]
Also in the electronic component chip storage cassette 10, the shutter 22 can be held in a closed state by rotating the knob 44 in the rotation hole 50. Moreover, it is possible to know whether or not the movement of the shutter 22 is stopped by the direction of the knob 44. Furthermore, when the electronic component chip is mounted on a circuit board or the like, after confirming the type of the electronic component chip, by introducing a mechanism for rotating the knob 44 into the feeder, an electronic component chip having a different characteristic is mistakenly introduced. It can prevent being thrown in.
[0024]
【The invention's effect】
According to the present invention, it is possible to stop the movement of the shutter while the shutter is closed at the discharge port of the case. Further, whether the shutter is movable or stopped can be confirmed by the state of the stopper. Therefore, it is possible to prevent the electronic component chip from leaking from the case 12 during transportation. Furthermore, when the electronic component chip is mounted on a circuit board or the like, after confirming the type of the electronic component chip, by introducing a mechanism for rotating the stopper 30 into the feeder, an electronic component chip having a different characteristic is mistakenly introduced. It can prevent being thrown in.
