DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a packaged tablet in which a tablet is stored in a space formed by a storage film having a bulging portion and a cover film adhered to the film, and the tablet is stored in the space. The present invention relates to an inspection method for checking whether or not the inspection has been performed, and an inspection device for the inspection method.

[0002]

2. Description of the Related Art A dome-shaped bulge is formed on a plastic storage film for storing and transporting tablets (including those in which powdery, liquid, or granular drugs are encapsulated). It is widely practiced to store tablets in the bulging portion, adhere a storage film with aluminum foil or the like, and close the bulging portion to form a packaged tablet. Usually, a transparent (including colored and transparent) plastic film is used for the storage film. In this case, whether or not a tablet is stored in the bulging portion can be easily identified by visual observation, image recognition, or the like.

[0003] When the packaged medicine has a high hygroscopicity or a high photoreactivity, a film having a high moisture-proof and light-shielding property is obtained by laminating an aluminum foil instead of a transparent plastic film on the storage film. May be used as a storage film.

[0004]

However, when such a film is used, it is not possible to visually sense whether or not a tablet is stored inside the bulging portion. This is because the storage film does not transmit light. On the other hand, for packaged tablets, the number of packages is counted and users (patients, etc.)
, It is necessary to ensure that the tablets are stored inside.

The present invention has been made in view of the above problems, and is a method for manufacturing a packaged tablet in which tablets are stored in a space formed by a bulging portion of a packaging film and a cover film. It is an object of the present invention to provide a method for producing a packaged tablet in which tablets are stored. It is another object of the present invention to provide an inspection method for reliably inspecting whether or not a tablet is packaged in a packaged tablet. Further, it is another object of the present invention to apply an inspection device capable of reliably performing such an inspection.

[0006]

According to a first aspect of the present invention, there is provided a storage film having a dome-shaped bulging portion for storing a tablet, and the tablet is adhered to the storage film to form the tablet. A cover film that forms a space for storing tablets with the storage bulge, and a tablet that is stored in the space formed by the tablet storage bulge and the cover film of the storage film, In the manufacturing method, the tablet is stored in the tablet storage bulge, and after the cover film is adhered to the storage film, the top of the tablet storage bulge is pressed toward the cover film side,
A method for producing a packaged tablet, comprising a step of removing the packaged tablet having a pushing amount equal to or more than a predetermined value.

Here, the storage film is formed by laminating a plastic film such as PET and a metal foil such as an aluminum foil, and has a low moisture permeability (high moisture resistance), a high light shielding property, a moisture-proof / light shielding film, and a film. High moisture-proof and light-shielding properties, such as an aluminum-deposited film in which aluminum is deposited on one surface or a film in which aluminum metal particles are dispersed in a resin such as nylon, are used. Further, an ordinary transparent (including colored transparent) plastic film may be used.

Further, as the cover film, a metal foil such as an aluminum foil or a plastic film can be used. Tablets include not only tablets such as conventional green compacts and sugar-coated tablets, but also powdered, liquid, or granular drugs encapsulated in capsules. In addition, as a drug,
It is not necessarily limited to medical drugs. That is, the present invention can be applied to the case of packaging tablets for drugs for animals and plants and other chemicals.

[0009] In addition to the method of eliminating independent packaged tablets, the method of eliminating packaged tablets having a pressing amount equal to or larger than a predetermined value, and when a plurality of packaged tablets are connected, this method of connection is used. There is a method of eliminating a plurality of packaged tablets at once.

When the top of the bulging portion is pressed toward the cover film, the top is depressed. But space (inside)
When there is a tablet, the amount of depression (the amount of depression) remains below a certain amount. This is because the tablet prevents further deformation against the pressing force. On the other hand, when there is no tablet inside, since the tablet is not prevented from being deformed, the bulging portion is crushed and the amount of depression (the amount of pushing) becomes large. Therefore, when the pushing amount exceeds a certain value, it is determined that the tablet is not stored, and if this is excluded, a packaged tablet in which the tablet is stored can be manufactured reliably.

The means for achieving the above object may further comprise a portion of the cover film surrounding the space while pressing the top of the tablet storage bulge toward the cover film. 2. The method for producing a packaged tablet according to claim 1, wherein the pill is pressed toward the tablet storage bulging portion.

Usually, the space formed by the bulging portion and the cover film in the packaged tablet is larger than that of the tablet to be packed, that is, the bulging portion is formed with a margin more than the size of the tablet to be packed. Therefore, even if the top of the bulging portion is pressed on the packaged tablet in which the tablets are packed, the top is pushed at least by the difference between the size of the space and the size of the tablet. Therefore, the difference from the pushing amount when there is no tablet (when the tablet is missing) becomes small.

Therefore, the tablet is packaged when the cover film is slightly deformed (pushed) to the space side by pressing the portion of the cover film surrounding the space toward the tablet storage bulging portion. Since the pushing amount in the case is reduced, the difference from the unlocked state becomes clearer.

The means for achieving the above object may further comprise a peripheral portion of the tablet storage bulge while pressing the top of the tablet storage bulge toward the cover film. 3. The method for producing a packaged tablet according to claim 1, wherein at least a part of the tablet is pressed toward the space side. 4.

Even after the pressing is released, the deformation of the top does not return, and the presence or absence of the tablet is confirmed by the pressing of the top, whereby a packaged tablet with the deformed top may be produced. Therefore, when at least a part of the periphery of the tablet storage bulge is pressed toward the space, when the pressing of the top is stopped, the deformation of the top returns more easily and reliably due to the elasticity of the packaging film. . Therefore, a packaged tablet with a deformed top is not produced.

In addition, by pressing the peripheral portion, the tablet moves to the center of the space and becomes difficult to move, so that the variation in the amount of pressing when there is a tablet is small, and the difference from the case where there is no tablet is clearer. become.

Further, in order to achieve the above object, a means according to a fourth aspect of the present invention is a packaging tablet wherein the bulging portion for storing tablets has a vertically long dome shape, and a top portion of the bulging portion for storing tablets is provided. 4. The package according to claim 3, wherein during pressing toward the cover film side, two longitudinal peripheral portions of the peripheral portion of the tablet storage bulging portion are pressed toward the space side, respectively. 5. This is a method for producing tablets.

When the bulging portion has a vertically long dome shape,
When two longitudinal peripheral parts of the peripheral part of the bulging part are pressed toward the space side, two peripheral parts in the longitudinal direction are pressed so as to sandwich the top part. Therefore, when the pressing of the top portion of the bulging portion is stopped, the deformation of the top portion returns more easily and reliably due to the elasticity of the packaging film.

Further, by pressing the two peripheral portions in the longitudinal direction, the tablet moves to the center of the space and becomes difficult to move. Differences become clearer.

Further, the means for achieving the above object is a storage film having a dome-shaped swelling portion for storing a tablet, and a swelling film adhered to the storage film, and the swelling film for storing a tablet is provided. A cover film that forms a space for storing tablets with the portion, and a tablet that is stored in a space formed by the tablet storage bulging portion and the cover film of the storage film,
The method for manufacturing a packaged tablet comprising: adhering the cover film to a storage film, and pressing a portion of the cover film that surrounds the space toward the tablet storage bulging portion, Pressing at least a part of the peripheral portion of the bulging portion toward the space side,
And, the step of pressing the top of the bulging portion for tablet storage toward the cover film side, and the step of removing the packaging tablet deformed by pressing the top is characterized by having a step of: It is a manufacturing method.

When the tablet is stored in the space, the top of the bulging portion is deformed, but when the tablet is not stored, the top is crushed and deformed. Therefore, by eliminating the deformed packaged tablet, a packaged tablet without a missing tablet state can be produced. In addition, in order to inspect the deformation of the top, in addition to visual inspection such as visual inspection, image processing, etc., mechanical,
Optical inspection is also possible.

In order to achieve the above object, the present invention provides a storage film having a dome-shaped tablet storage swelling part, and a tablet storage film having a dome-shaped tablet storage swelling part.

The packaged tablet having the pushing amount described above is a packaged tablet inspection method, wherein it is determined that a tablet is not stored.

When the top of the bulging portion is pressed toward the cover film, the top is depressed. But space (inside)
When there is a tablet, the amount of depression (the amount of depression) remains below a certain amount. This is because the tablet receives the pressing force and prevents further deformation. On the other hand, when there is no tablet inside, the deformation by the tablet is not prevented, so that the amount of depression (the amount of pushing) becomes large. Therefore, it can be determined that the tablet is not stored in the packaged tablet in which the pushing amount is equal to or more than the predetermined value, and the tablet is securely stored in the packaged tablet without using visual means. Can be determined.

Further, in order to achieve the above-mentioned object, the means according to claim 7 is such that when pressing the top of the bulging portion for tablet storage toward the cover film side, the cover film surrounds the space. 7. The method for inspecting a packaged tablet according to claim 6, wherein the portion is pressed toward the tablet storage bulging portion.

Usually, the bulging portion is formed with a margin in size more than the tablet to be packed. Therefore, even if the top of the bulging portion is pressed down on the packaged tablet in which the tablets are stored, the top is pushed at least by the difference between the size of the space and the size of the tablet. Therefore,
The difference from the pushing amount when there is no tablet (when the tablet is missing) is small.

Then, the portion of the cover film that surrounds the space is pressed against the bulging portion for tablet storage, so that the cover film is slightly deformed (pushed) toward the space, and the tablets are packaged. Since the pushing amount in the case is reduced, the difference from the unlocked state becomes clearer.

Further, the means according to claim 8 for achieving the above object is characterized in that, when the top of the tablet storage bulge is pressed toward the cover film side, the periphery of the tablet storage bulge is provided. The package tablet inspection method according to claim 6, wherein at least a part of the part is pressed toward the space.

If at least a part of the peripheral portion of the tablet storage bulging portion is pressed toward the space side, when the pressing of the top portion is stopped, the elasticity of the packaging film makes it easier and more reliable. The deformation returns. Further, by pressing the peripheral portion, the tablet moves to the center of the space and becomes difficult to move, so that the fluctuation of the pushing amount when there is a tablet becomes small, and the difference from the case where there is no tablet becomes clearer.

Further, in order to achieve the above object, a means according to a ninth aspect of the present invention is that the tablet storage swelling portion is a packaged tablet having a vertically long dome shape, wherein the tablet storage swelling portion has a top portion. 9. When pressing down toward the cover film side, two longitudinal peripheral portions of the peripheral portion of the tablet storage swelling portion are pressed toward the space side, respectively. This is an inspection method for packaged tablets.

When the bulging portion has a vertically long dome shape,
When two longitudinal peripheral parts of the peripheral part of the bulging part are pressed toward the space side, two peripheral parts in the longitudinal direction are pressed so as to sandwich the top part. Therefore, when the pressing of the top portion of the bulging portion is stopped, the deformation of the top portion returns more easily and reliably due to the elasticity of the packaging film. In addition, by pressing the two peripheral portions in the longitudinal direction, the tablet moves to the center of the space and becomes difficult to move, so that the variation in the pushing amount when there is a tablet is small, and the difference from the case where there is no tablet is different. Be clearer.

Further, the means for achieving the above object is a storage film having a dome-shaped bulging portion for storing a tablet, and a film for adhering to the storing film, the bulging portion for storing a tablet. And a cover film forming a space for storing tablets in the space, and a tablet stored in a space formed by the tablet storage swelling portion and the cover film of the storage film; and A method for inspecting a packaged tablet for inspecting whether or not a tablet is stored,
While pressing the portion of the cover film surrounding the space toward the tablet storage bulging portion, pressing at least a part of the periphery of the tablet storage bulge toward the space side, and After pressing the top of the tablet storage bulge toward the cover film side, the top of the tablet storage bulge is pressed into and deformed by the packed tablet,
This is a method for inspecting a packaged tablet, wherein it is determined that a tablet is not stored.

When a tablet is stored in the space, the top of the bulging portion is deformed, but when no tablet is stored, the top is crushed and deformed. Therefore, it can be determined that the deformed packaged tablet does not contain the tablet. In addition, to inspect the deformation of the top,
In addition to visual inspections such as image processing, mechanical and optical inspections are possible.

Further, in order to achieve the above object, the means according to the eleventh aspect includes a storage film having a dome-shaped bulging portion for storing tablets, and a bulging portion for adhering to the storing film, the bulging portion for storing tablets. And a cover film forming a space for storing tablets in the space, and a tablet stored in a space formed by the tablet storage swelling portion of the storage film and the cover film; An inspection device for a packaged tablet for inspecting whether or not the tablet is stored,

A packaging tablet inspection apparatus characterized in that:

When the top of the bulging portion is pressed toward the cover film by the top pressing member, the top is depressed. However, when there is a tablet in the space (inside), the amount of depression (the amount of pushing) remains below a certain amount. This is because the tablet supports the pressing force and prevents further deformation. On the other hand, when there is no tablet inside, the deformation by the tablet is not prevented, so that the amount of depression (the amount of pushing) becomes large.

Therefore, if the push-in amount determining means determines whether or not the push-in amount is equal to or more than a predetermined value, the inspection device for a packaged tablet can surely inspect whether the tablet is stored in the packaged tablet. It can be. Also,
The presence or absence of a tablet in a packaged tablet can be inspected without using expensive determination means such as image processing.

Further, in order to achieve the above object, the means according to the twelfth aspect is characterized in that when the top of the tablet storage bulge is pressed toward the cover film by the top pressing member, The package tablet inspection device according to claim 11, further comprising: a cover film pressing member that presses a portion surrounding the space toward the tablet storage bulging portion.

Usually, the bulging portion is formed with a margin in size more than the tablet to be packed. Therefore, even if the packed tablet in which the tablets are stored, even if the top of the bulging portion is pressed by the top pressing member, at least the difference between the size of the space and the size of the tablet is pressed into the top. It will be. Therefore, the difference from the pushing amount when there is no tablet (when the tablet is missing) becomes small.

Therefore, the tablet is packaged when the cover film is slightly deformed (pushed) toward the space side by pressing the portion of the cover film surrounding the space toward the tablet storage bulging portion. Since the pushing amount in the case is reduced, the difference from the unlocked state becomes clearer.

Further, the means according to claim 13 for achieving the above object is characterized in that, when the top of the swelling portion for tablet storage is pressed toward the cover film side by the top holding member, the tablet storage swelling portion is provided. The package tablet inspection device according to claim 11 or 12, further comprising a peripheral portion pressing member that presses at least a part of a peripheral portion of the bulging portion toward the space side.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a packaged tablet 10 according to the present embodiment. The storage film 1 is a film having a low moisture permeability and a high light-shielding property.
It has a three-layer structure in which aluminum foil is laminated between films. This storage film 1 has a length of 27 m.
m, 16mm in short direction, 6mm in depth
Swelling portion 1 having a vertically long dome shape having a substantially semicircular cross section at the top
a is 35 mm long (longitudinal direction) and 24 m wide (short direction)
The tablet tablets 110 are formed in a grid pattern at a pitch of m, and the stored tablets 10 are connected vertically and horizontally (see FIG. 1A).

As shown in the broken cross-sectional view of FIG. 1 (b), each bulging portion 1a has a substantially cylindrical capsule tablet having a length of 16 mm and a diameter of 5 mm, both ends of which are hemispherical, in which a powder drug is sealed. 2 are accommodated, and a cover film 3 made of aluminum foil adheres to the accommodation film 1 to cover the bulging portion 1a. Therefore, the bulging portion 1a and the cover film 3
These form a space S for storing the tablets 2.

In such a packaged tablet 10, whether or not the tablet 2 is stored in the space S cannot be visually confirmed from the outside. Storage film 1 also cover film 3
Is also opaque.

Then, the storage of the tablet 2 is confirmed as follows. That is, as shown in FIG. 2A, the top 1t of the bulging portion 1a of the film 1 is pressed by the pressing pin 21 toward the cover film side (downward in the figure) with a predetermined load. At this time, when the tablet 2 is stored in the space S, the tablet keeps a certain height without being crushed because the tablet supports the load of the holding pin. That is, the pushing amount p of the pin 21 is equal to or less than a certain amount. (See FIG. 2 (b)). On the other hand, when there is no tablet 2 in the space S (when the tablet is missing), since the bulging portion 1a has no supporting tablet, it is crushed more and the pin 21
Is greater than a predetermined amount (see FIG. 2 (c)).

Accordingly, by determining the pushing amount p of the pin 21, the missing tablet can be detected, and the missing tablet 10 can be detected. Can be eliminated.

Further, in the second embodiment, FIG.
As shown in the figure, from the cover film 3 side (the lower side in the figure),
While pressing up the cover film 3 upward in the figure with the cover film pressing plate 22 having the protruding portion 22a (see FIG. 3B), the pressing pin 21 presses the top 1t of the bulging portion 1a (FIG. 3A). reference). The protrusion 22a is provided in each space S
Is provided at a position corresponding to the shape, and approximates the shape of the substantially bulging portion,
And it has a dome shape smaller than the bulging portion.

In this manner, as shown in FIG. 3C, the tablet 2 is lifted upward together with the cover film 3 in the figure, and the pushing amount p of the holding pin 21 becomes a small value. Moreover, when the cover film 3 is pressed by the projection 22a, the tablet 2 is lifted upward in the drawing. At this time, since the top of the bulging portion 1a has a substantially semicircular cross section, the tablet 2 moves to the upper center. That is, since the position of the tablet 2 can also be restricted to a substantially constant position, the variation of the pushing amount p is reduced, and the determination with higher accuracy can be performed.

Further, in the third embodiment, in addition to pressing the cover film 3 with the cover film pressing plate 22 as in the second embodiment, as shown in FIG.
The peripheral portion of the bulging portion 1a is pressed toward the space S. That is, the protrusions 23a push down the peripheral pressing plates 23 formed at two locations on the left and right sides in the figure along the longitudinal direction (perpendicular to the paper surface) of the periphery of the bulging portion 1a.
a presses the peripheral portion in the longitudinal direction of the bulging portion 1a toward the space S (obliquely downward in the figure). By doing so, the pushing amount p becomes smaller.

By pressing the peripheral portion of the bulging portion 1a, the tablet 2 is moved to the central portion, the variation in the pushing amount p is reduced, and it is easier to distinguish from the lost tablet and the accuracy is high. Judgment becomes possible.

In addition, when the periphery of the bulging portion 1a is pressed by the projection 23a while the top portion 1t of the bulging portion 1a is pressed by the pressing pin 21, the pressing deformation is caused by the elasticity of the packaging film 1. Is easily returned, and the appearance of the packaged tablet after the inspection for such missing tablets is improved (FIG. 5 (b)
reference). That is, when the pin 21 is simply pressed by the pressing pin 21, the bulging portion 1 a is moved even if the pin 21 is moved upward (returned) after it is confirmed that the tablet 2 is stored.
There was a case where the deformation of the top 1t did not return (the case where the trace of the holding pin remained) (see FIG. 5 (b)). However, in this embodiment, as shown in FIG.
Is small, and the protrusion 23a presses the periphery of the bulging portion 1a. Therefore, as the pin 21 returns upward, the deformation of the top portion 1t returns, and the bulging portion 1a assumes the original dome shape.

Therefore, by doing so, the holding pin 2
After pressing with 1, it is determined whether deformation is left on the top 1 t of the bulging portion 1 a by a method such as visual observation or image recognition.
It is also possible to determine whether or not the tablet 2 is stored in the space S. By doing so, the above determination can be made while also performing an appearance inspection of the packaged tablet, which is convenient.

Next, a manufacturing method, an inspection method and an inspection apparatus for a packaged medicine according to the third embodiment will be described with reference to FIG.
This will be described in detail with reference to FIGS. FIG. 6A is a plan view of the cover film pressing plate 22 described above.
(b) is a sectional view taken along the line BB '. In this example, the protrusions 22a have a flat upper surface and a rounded chamfered periphery, and each of the protrusions 22a has a vertical length of 3 rows and a horizontal width of 4 rows at a pitch corresponding to the above-mentioned bulging portion 1a. Is formed. The dimensions of the protruding portion 22a are determined by the bulging portion 1a of the packaging tablet and the tablet 2
In this example, the longitudinal direction (vertical direction in the figure) is 18 mm, and the lateral direction (horizontal direction in the figure) is 12 m.
m, height 4 mm, r = 3 mm chamfer.

FIG. 7A is a plan view of the peripheral pressing plate 23, and FIG. 7B is a cross-sectional view taken along the line CC ′. Four grooves 23b (bottom dimension: 8 mm) are formed in the peripheral pressing plate 23 in accordance with the lateral pitch of the bulging portion 1a, and a protrusion 23a is formed between adjacent grooves 23b. The protruding portion 23a presses the periphery of the bulging portion 1a of the packaged tablet. Also, in the groove 23b, three pressing pin through holes 23c are formed in accordance with the vertical pitch of the bulging portion 1a. In addition, both ends (upper and lower parts in FIG. 7A) of each groove 23b are widened in order to guide the bulging portion 1a of the packaged tablet and guide it to the groove 23b.

FIG. 8 shows the through hole 23 of the peripheral pressing plate 23.
It is explanatory drawing which shows the press pin 21 penetrably inserted in c, and the mechanism of its periphery. The holding pin 21 has a substantially columnar shape with an end portion (upper end in the drawing) 21a chamfered, and the lower end is fastened to the pin holding member 24 by a screw. Further, the pin 21 is movable vertically in the figure by a bearing 27. The pin holding member 24 is
It is supported by a spring 25 whose one end is held in a concave portion 26 a of the lift 26. In addition, a position indicating piece 24a is formed on the periphery of the pin holding member 24.

When the lift 26 moves up and down, the holding member 24 moves up and down through the spring 25. Further, the pin 21 attached to the holding member 24 is guided by the bearing 27 so as to be freely inserted into the through hole 23c. However, the elevator 26
When the amount of rise of the holding member 24 becomes equal to or more than a predetermined value, the holding member 24
The upper surface 24u contacts the lower surface 27d of the bearing 27, so that the pin 21 does not rise any further.

Using such members and mechanisms, the absence of a packaged tablet is determined. That is, as shown in FIG. 9, the package tablet sheet 110 is set between the cover film pressing plate 22 and the peripheral pressing plate 23 such that the bulging portion faces downward, that is, faces the peripheral pressing plate 23. Note that, for ease of comparison, the description will be made with the second package tablet from the left in the figure being in the missing state.

Next, the cover film pressing plate 22 is moved downward (downward) in the figure. Then, the protrusion 22a presses the cover film 3, and the film 3 is slightly dented. As a result, the gap in the thickness direction between the tablet 2 and the bulging portion 1a is eliminated or sufficiently reduced. Further, the bulging portion 1a abuts on the protruding portion 23a of the peripheral pressing plate 23 at the peripheral portion (two locations) in the longitudinal direction and is pressed.

Further, when the elevator 26 is raised, FIG.
As shown in FIG. 1, the pin holding member 24 and the pin 21 rise through the spring 25. However, the tip 2 of the pin 21
When the bulge 1a comes into contact with the bulge 1a, the rise of the pin 21 is suppressed, and the bulge 1a is pushed by the pin 21 by a small amount. Since tablet 2 is packaged in package tablet 10,
Even if the pin 21 tries to crush the bulging portion 1a, the tablet 2
Is prevented from being crushed.

However, when the tablet 2 is not contained (in the missing tablet state) as in the second packaged tablet from the left in FIG. 11, the bulging portion 1a is crushed by the pin 21, so that the tablet 2 is Pin 21 rises higher than in certain cases. That is, in the unlocked state, the pushing amount of the pin 21 increases.

Therefore, as is clear from FIG. 11, the height of the position indicating piece 24a of the holding member 24 interlocking with the pin 21 is different from the others only in the unlocked state. Therefore, by detecting the position of the position display piece 24a,
The presence or absence of the unlocked state can be confirmed.

The position of the position display piece 24a may be confirmed for each of the pins 21. However, as shown in FIG. 11, a light beam such as a laser beam (indicated by an optical axis L) moves from left to right in the figure. ), If the light beam does not reach the light receiving unit (not shown) on the right side in the figure, it is determined that at least one of the four wrapped tablets 10 is in the missing state. In this way, four packaging tablets 10 are taken as one unit,
By inspecting this for three units (for three rows) at the same time,
A package tablet sheet 110 having 12 package tablets 10 can be inspected at a glance.

The packaged tablet sheet 110 determined to have missing tablets is not sent to the next process and is excluded as a defect, so that the unpackaged tablets do not flow out to the subsequent process or the market. .

After the return operation, that is, after the elevating platform 26 is lowered and the cover film pressing plate 22 is raised,
The package tablet sheet 110 is as shown in FIG. That is, the bulging portion 1a of the packaged tablet 10 containing the tablet returns to the original dome shape. Projecting portion 23 of peripheral pressing plate 23
a while pressing the periphery of the bulging portion 1a with the pin 21
This is because, when t is pressed, the pin 21 quickly returns to the original shape when the pin 21 separates from the bulging portion 1a due to the elasticity of the storage film 1, the elasticity of the tablet 2, and the like. This is like a dome-shaped bulge having a narrow width apparently by pressing the periphery of the bulge 1a with the protrusion 23a. In addition, since the amount of pressing of the pin 21 is reduced due to the tablet 2, it is considered that the pressing deformation easily returns. Therefore, when the packaged tablet 10 containing the tablet 2 is inspected as described above, no portion remains after the bulging portion 1a is pressed by the pin 21.

On the other hand, in the case of a missing tablet, since the pin 21 is pushed in a large amount and is not supported by the tablet 2, the bulging portion 1a is greatly deformed and the deformation is not restored. Therefore, if the bulging portion 1a is deformed after the bulging portion 1a is pressed by the pin 21 as described above, it can be inspected by determining that the bulging portion 1a is in the unlocked state.
The inspection for the presence or absence of such deformation may be performed by visual inspection or image processing, or by mechanically or optically detecting the height of the bulging portion.

It should be noted that the present invention is not limited to the above embodiment, and it is needless to say that the present invention can be appropriately modified and used without departing from the gist of the present invention. For example, in the above embodiment, the pushing amount of the pin 21 is set to the position indicating piece 2 of the pin holding member 24 linked therewith.
Although the determination is made based on the position of 4a, that is, whether the display piece 24 blocks the optical axis L, the position or the movement amount of the pin 21 may be directly measured.

As described above, the method of measuring the positions of the display piece 24 and the pin 21 is to detect whether or not the laser beam is interrupted, to use a photoelectric detector, or to mechanically detect with a microswitch or the like. Various methods can be adopted. Further, in the above embodiment, the method and apparatus for inspecting at once the packaging tablet sheet 110 in which a plurality of packaging tablets 10 are connected as a unit of production have been exemplified, but it is possible to produce and inspect individual packaging tablets in the same manner. Needless to say, a plurality of packaged tablet sheets can be inspected simultaneously.
