  However, in the medicine storage device described in Patent Document 1, since the sensor for detecting the presence or absence of medicine is arranged for each medicine to be stored, the versatility of the cassette is lacking. When storing different types of medicines for each medicine of the same size, a cassette with multiple sensors must be prepared for each medicine size at a position corresponding to the medicine to be stored. Become. On the other hand, in the medicine storage device as described in Patent Document 2, the position of the medicine in the rearmost part of the medicine row is measured using a non-contact type distance measuring device that measures the distance from the medicine by laser or ultrasonic waves. For example, even if the drug size is different, it is not necessary to prepare a cassette for each drug size, but laser and ultrasonic non-contact rangefinders are expensive and the device configuration is compared. The cost of the equipment is high.

  The present invention has been made to solve such problems of the prior art, and can arrange and store one or two or more medicines each containing a medicine in a medicine container in a medicine row along a predetermined storage direction, and The cassette has a chemical stopper for stopping the chemical on one side of the chemical row on one side in the storage direction, and is configured to apply a biasing force toward the one side in the storage direction with respect to the chemical row. When the medicine stopped by the medicine stopper by the urging force toward the one side in the storage direction in the medicine row is taken out, the next medicine is further stopped by the medicine stopper, thus the medicine. A cassette for storing medicine in which medicines in a row are sequentially dispensed, and a medicine storage apparatus equipped with the cassette, are excellent in versatility of the cassette, and are compared without using expensive members. While suppressing the apparatus costs low with a simple apparatus configuration, and to provide a chemical storage device including a cassette and it chemicals storage can be obtained stock quantity of the medicine to be accommodated in the cassette.

  In order to solve the above-mentioned problems, the present invention provides predetermined storage of one or more drugs each containing a drug (eg, tablet, powder, injection solution, etc.) in a drug container (eg, vial, ampoule, bottle, etc.). The medicine rows can be arranged and stored side by side in the medicine row along the direction, and have a medicine stopper for stopping the medicine on one side of the medicine row on one side of the storing direction, and toward the one side in the storing direction with respect to the medicine row. A cassette configured to apply an urging force, and when the medicine stopped at the medicine stopper by the urging force toward the one side in the storage direction in the medicine row is taken out, the next medicine In the chemical storage cassette in which the chemicals are stopped by the chemical stopper and thus the chemicals in the chemical row are sequentially dispensed, the sheet surface extends along the storage direction and the sheet surface is pressed. And a position sensitive sheet sensor whose output changes in response to a change in the pressing position on the sheet surface in the storage direction, and at least the other corresponding to the position of the medicine on the other side of the medicine row It is comprised so that the said sheet surface of the said sheet sensor can be pressed in the side medicine corresponding position, The said sheet sensor detects the pressing position to the said sheet surface in the said other side medicine corresponding position, It is characterized by the above-mentioned. Provide chemical storage cassettes.

  In order to solve the above-mentioned problems, the present invention is also a medicine storage device comprising one or more medicine storage cassettes according to the present invention, wherein the medicine stored in the one or more cassettes is stored in the medicine storage apparatus. Detected by a storage unit for storing medicine sizes in the storage direction in advance, reading means for reading out the medicine sizes stored in the storage unit, and the sheet sensor of the one or more cassettes, respectively. And calculating means for obtaining the stock quantity of the medicines stored in the one or more cassettes based on the other-side medicine corresponding position and the medicine sizes read by the reading means, respectively. A chemical storage device characterized by the above is also provided.

  According to the medicine storage cassette and the medicine storage device according to the present invention, the sheet sensor detects the pressing position on the sheet surface at the other-side medicine-corresponding position. In this case, the output changes in response to the change in the pressing position on the sheet surface at the other-side medicine-corresponding position accompanying the dispensing, so that the other-side medicine-corresponding position after the dispensing is detected. When storing multiple types of drugs with different drug sizes for each drug of the same size as in the conventional device, it is not necessary to prepare a cassette corresponding to the size of the stored drug for each drug size. Accordingly, the cassette has excellent versatility, and as a sensor for detecting chemicals, it is cheaper than the non-contact type distance measuring device using a laser or an ultrasonic wave used in a conventional apparatus. In the cassette, the sheet sensor extends in the form of a sheet along the storage direction, and is configured to be able to press the sheet surface of the sheet sensor at least at the other side corresponding to the medicine. Therefore, the apparatus cost can be kept low with a relatively simple apparatus configuration, and the medicine storage device includes the storage unit, the reading unit, and the calculation unit. Or memorize | stores the chemical | medical agent size in the said storage direction of the said chemical | medical agent accommodated in two or more cassettes beforehand, respectively reads the said chemical | medical agent size memorize | stored in the said memory | storage part in the said reading means, The other side medicine corresponding position detected by the sheet sensor of the one or more cassettes and the reading means Stock quantity of the medicine to be accommodated in the one or more cassettes based on said drugs size read respectively can be obtained respectively.

  In the medicine storage cassette according to the present invention, the case of the following (a) to (c) is configured to apply an urging force toward the one side in the storage direction with respect to the medicine row. It can be illustrated. That is,

(A) In the case where the medicine row is configured to be aligned and housed with a low inclination on one side of the medicine row and a high inclination on the other side of the medicine row, in this case, the medicine row is caused by its own weight. An urging force can be applied to one side in the storage direction. Moreover, you may further provide the pushing member arrange | positioned at the said chemical | medical agent row | line | column other side so that a reciprocation is possible along the said storage direction. In this case, the pressing member can press the medicine row to one side in the storing direction by its own weight.
(B) a pressing member disposed on the other side of the medicine row so as to be capable of reciprocating along the storing direction; and a pressing member biasing member that biases the pressing member toward the one side in the storing direction. If provided, in this case, the pressing member can press the drug row to one side in the storage direction by the urging force of the urging member for the pressing member. As the urging member for the pressing member, a constant torque spring that urges the pressing member toward the one side in the storage direction with a substantially constant urging force may be preferably used.
(C) When (a) and (b) are combined, in this case, the pressing member presses the drug row to one side in the storing direction by its own weight together with the urging force of the urging member for the pressing member. Can do.

  In any case, the sheet sensor typically has an electric resistance value that changes in response to a change in the pressing position on the sheet surface in the storing direction when the sheet surface is pressed. Can be mentioned.

In the medicine storage cassette according to the present invention, as a case where the sheet surface of the sheet sensor can be pressed at the other side medicine corresponding position corresponding to the position of the medicine on the other side of the medicine row, The following cases (d) to (f) can be exemplified. That is,
(D) When the said chemical | drug | medicine row | line | column is comprised so that the said sheet | seat surface of the said sheet | seat sensor may be pressed directly, in this case, the said sheet | seat surface of the said sheet | seat sensor is pressed in the position of the chemical | medical agent of the said chemical | medical agent row | line | column. be able to. Examples of the sheet sensor that can be employed in this case include a sensor whose electric resistance value is increased on one side in the storing direction and gradually decreases toward the other side when the sheet surface is pressed.
(E) It further includes a pressing member disposed on the other side of the medicine row so as to be reciprocally movable along the storing direction, and the pressing member has the sheet sensor on the sheet surface in the storing direction. When a rolling member that rolls along is provided, in this case, the pressing member can move while pressing the rolling member against the sheet surface via the rolling member due to its own weight or the like.
(F) a pressing member disposed on the other side of the medicine row so as to be reciprocally movable along the storing direction; and the pressing member includes a sheet sensor on the sheet surface in the storing direction. When a rolling member that rolls along and a biasing member for a rolling member that biases the rolling member toward the seat surface are provided, in this case, the push member is the rolling member. The urging member for member can be moved while pressing the rolling member against the sheet surface via the rolling member.

  And in the case of said (e) and (f), the said sheet | seat surface of the said sheet sensor can be pressed in the position of the said rolling member provided in the said pressing member. In this case, when a cylindrical member or a spherical member is adopted as the rolling member, the rolling member can make a line contact or a point contact with the sheet surface, so that the sheet surface can be surely secured. And the detection accuracy of the sheet sensor can be improved. Furthermore, in the case of (f), the rolling member is pressed against the sheet surface by the rolling member urging member, so that the sheet surface can be more reliably pressed, and the sheet sensor The detection accuracy can be further improved.

  In the medicine storage apparatus according to the present invention, the computing means reads the other-side medicine corresponding position detected by the sheet sensor of the one or more cassettes and the reading means respectively. When obtaining the stock quantity of the medicine stored in the one or two or more cassettes based on the medicine size, for example, the calculation means is detected by the sheet sensor of the one or two or more cassettes, respectively. Further, the length of the medicine row is measured based on the position corresponding to the other side medicine, and the 1 or 2 is calculated from the relationship between the measured medicine row length and the medicine size read by the reading means. You may obtain | require the stock quantity of the said chemical | medical agent accommodated in the above cassette, respectively.

  By the way, one or two or more medicines respectively containing medicines in medicine containers can be arranged and stored in a medicine row along a predetermined storage direction, and the medicine on one side of the medicine row is stopped on one side of the storage direction. A cassette having a medicine stopper and configured to apply an urging force toward one side in the storage direction with respect to the medicine row, wherein the urging force toward one side in the storage direction in the medicine row In the medicine storage cassette, when the medicine stopped by the medicine stopper is taken out, the next medicine is further stopped by the medicine stopper and thus the medicines in the medicine row are sequentially dispensed. In the case where the other side of the row is provided with a pressing member that can be reciprocated along the storing direction, the pressing member is always urged to one side in the storing direction. At the time of replenishing the medicine, the pushing member always comes to the one side in the storing direction, so it is necessary to replenish the medicine while moving the pushing member to the other side in the storing direction. bad.

Therefore, for example, a chemical storage cassette can be configured as follows. That is,
(G) When the pressing member is formed in a curved shape so that the surface facing the drug row gradually moves away from the drug row as it goes upward,
(H) When a holding member that detachably holds the push member on the other side in the storage direction is provided,
(I) This is a case where (g) and (h) are combined.

  In the case of (g) and (i), since the surface of the pressing member that faces the drug row is formed in a curved surface, when the drug is replenished, the drug is brought into contact with the curved surface. By inserting from above, the medicine can be smoothly inserted from above while moving the pushing member to the other side in the storage direction, thereby facilitating insertion work and improving workability of replenishment work. Can be improved.

  In the case of (h) and (i), when the medicine is replenished by holding the pressing member on the other side in the storage direction with the holding member, the pressing member is on the one side in the storage direction. Therefore, the workability of the replenishing work can be improved. In this case, at least one of the portion of the pressing member that contacts the holding member and the portion of the holding member that contacts the pressing member is made of a magnet, and the other is made of a magnetic material or a magnet. Can do.

  In addition, in a medicine storage device including one or more such cassettes, when the cassette is mounted, the pressing member held on the other side in the storage direction by the holding member is pulled away from the holding member. It is preferable that it is comprised. For example, the cassette is configured to be mounted so as to be capable of reciprocating along the storage direction, and in the mounting state of the cassette, one side in the storage direction from the position of holding the push member of the holding member In addition, it is preferable that a protruding member protruding so as to come into contact with the pressing member is provided. By doing so, the pressing member held on the other side in the storage direction by the holding member is separated from the holding member by the protruding member, for example, when the cassette is mounted, and shifts to the one side in the storage direction. Therefore, in the medicine storage device configured as described above, since the push member is separated from the holding member when the cassette is mounted, the cassette is mounted while the push member is held by the holding member when the replenishment operation is completed. However, it is possible to prevent a mistake in releasing the set of the pressing portion with respect to the holding member.

  As described above, according to the present invention, one or two or more medicines each containing a medicine in a medicine container can be arranged and stored in a medicine row along a predetermined storage direction, and the medicine is provided on one side of the storage direction. A cassette having a chemical stopper for stopping chemicals on one side of the row and configured to apply a biasing force toward the one side in the storage direction with respect to the chemical row, wherein the storage is included in the chemical row When the medicine stopped at the medicine stopper by the urging force to one side in the direction is taken out, the next medicine is further stopped at the medicine stopper, and thus the medicines in the medicine row are sequentially dispensed. A cassette for storing chemicals and a chemical storage apparatus including the same, and having excellent versatility of the cassette, and without using an expensive member, the apparatus cost can be reduced with a relatively simple apparatus configuration. While suppressing Ku, it is possible to provide a chemical storage device including a cassette and it chemicals storage can be obtained stock quantity of the medicine to be accommodated in the cassette.

The length d of the ampoule row 1a can be measured by obtaining the distance d based on the output voltage of the sheet sensor 130 at the pressing plate roller position P where the sheet surface 130a is pressed. For example, when the ampule size S stored in advance in the storage unit 12a is 20 mm, the sheet sensor 130 detects the pressing position on the sheet surface 130a at the pressing plate roller position P, and for example, an ampule of 180 mm When the length d of the row 1a is measured, the computing means M2 uses the ampule size S (= 20 mm / piece) obtained by reading the measured ampule row 1a length d (= 180 mm) by the reading means M1. The value divided by (= 9) is the stock quantity of the ampule 1 stored in the cassette 100. For example, when the ampoule 1 is paid out from the ampoule row 1a, the output voltage changes in response to the change in the pressing position on the sheet surface 130a at the pressing plate roller position P accompanying the paying out. When the subsequent pressing plate roller position P is detected and, for example, the length d of the 160 mm ampoule row 1a is measured, the measured ampoule row 1a length d (= 160 mm) is read by the reading means M1. The value (eight) divided by the issued ampule size S (= 20 mm / piece) is the stock quantity of the ampule 1 after the payout. Thereby, the control apparatus 12 can obtain | require automatically the inventory quantity of the ampule 1 accommodated in the cassette 100, and can perform appropriate inventory management.

The shaft 144z ′ is rotatably supported in support grooves 1421z provided in the push plate 142z ′. Accordingly, the pressing member 140z can press the sheet surface 130a of the sheet sensor 130 at the position P of the roller 144z. In the cassette 100z, the pressing member 140z can move while pressing the roller 144z against the sheet surface 130a via the roller 144z by its own weight.

  The pressing member urging member 150z is an inclined base having a trapezoidal cross section formed so that the ampoule row 1a is aligned and housed at a low angle on the one side 1a 'of the ampoule row and high on the other side 1a' 'of the ampoule row. Thus, the medicine mounting portion 110 can be supported by the bottom surface, whereby the ampoule row 1a ′ is given a biasing force to the one side X1 in the storing direction by its own weight, and the pressing member 140z The ampoule row 1a can be pressed against the one side X1 in the storage direction by its own weight.

  By the way, in the chemical storage cassettes as shown in FIGS. 2A to 2c and FIGS. 5A to 7C, the pressing members 140 are disposed on the other side 1a ″ of the ampoule row 1a so as to be reciprocally movable along the storage direction X. 140x, 140y, 140z are provided, and this pushing member is always urged to one side X1 in the storage direction. At this time, when the ampoule 1 is replenished, the pushing member always comes to one side X1 in the storage direction. The ampoule 1 needs to be replenished while moving the push member to the other side X2 in the storage direction X, and the workability of the replenishment work is poor.

  Therefore, as shown in FIG. 8, the pressing member 140 ′ may be formed in a curved shape so that the surface 140 a ′ facing the ampoule row 1 a gradually moves away from the ampoule row 1 a as it goes upward. FIG. 8 shows an example 100 ′ in which a pressing member 140 ′ having a curved surface 140a ′ facing the ampoule row 1a is provided in place of the pressing member 140z in the cassette 100z shown in FIGS. 7A to 7C. ing.

  In this cassette 100 ′, the surface 140a ′ facing the ampoule row 1a of the pressing member 140 ′ is formed in a curved surface. Therefore, when the ampoule 1 is refilled, the ampoule 1 is moved upward along the curved surface 140a ′. The ampoule 1 can be inserted smoothly from above while moving the pushing member 140 ′ to the other side X2 in the storing direction, thereby facilitating the insertion work and improving the workability of the replenishment work. Can be improved.

  Further, as shown in FIG. 9, the medicine storage cassette 100 ′ may include a holding member 160 that detachably holds the pressing member 140 ′ on the other side X <b> 2 in the storage direction. FIG. 9 shows a case where the cassette 100 ′ is installed in the chemical storage device 10 ′ that stores the cassette 100 ′ having the holding member 160 that holds the pressing member 140 ′ on the other side X2 in the storage direction. The state which is comprised so that pushing member 140 'hold | maintained by the member 160 at the other side X2 of the accommodation direction may be pulled apart from this holding member 160 is shown.

  More specifically, in the cassette 100 ′ shown in FIG. 9, the holding member 160 is made of a magnetic material as a magnet receiver, and the portion 140a ″ of the pressing member 140 ′ that contacts the magnet receiver 160 is made of a magnet. Thus, when the ampule 1 is replenished by the operator or the like by holding the pressing member 140 ′ on the other side X 2 in the storing direction by the magnet receiver 160 by the magnetic force of the magnet 140 a ″ (see FIG. 9A). (Refer to FIG. 9B.) Since the pressing member 140 ′ does not come to the one side X1 in the storage direction, the workability of the replenishment work can be improved.

  Further, in the medicine storage device 10 ′ shown in FIG. 9, the cassette 100 ′ is configured so as to be reciprocally movable along the storage direction X. When the cassette 100 ′ is mounted, A block 170 (an example of a protruding member) is provided on the one side X1 in the storage direction from the position Q for holding the pressing member 140 ′ and protruding so as to come into contact with the pressing member 140 ′.

  In such a medicine storage device 10 ′, the pressing member 140 ′ held on the other side X2 in the storage direction by the magnet receiver 160 by the magnetic force of the magnet 140a ″ is separated from the magnet receiver 160 by the block 170 when the cassette is mounted. (See FIG. 9C.) Accordingly, in the medicine storage device 10 ′ configured in this manner, the push member 140 ′ is pulled away from the magnet receiver 160 by the block 170 when the cassette is mounted. Therefore, even if the cassette 100 ′ is mounted while the pressing member 140 ′ is held on the magnet receiver 160 when the replenishment operation is completed, an error in releasing the set of the pressing member 140 ′ with respect to the magnet receiver 160 can be prevented.

  According to the medicine storage cassettes 100, 100x, 100y and 100z and the medicine storage device 10 described above, the sheet sensor 130 detects the pressing position on the sheet surface 130a at the other-side medicine-corresponding position P. When the ampule 1 is paid out from the row 1a, the output voltage is corresponding to the change in the pressing position on the sheet surface 130a at the position P corresponding to the position of the ampule 1 on the other side 1a "of the ampule row accompanying the payout. By changing, it is possible to detect the position P after the dispensing, and when storing multiple types of medicines with different medicine sizes for each medicine of the same size as in the conventional device, it corresponds to the size of the medicine to be stored There is no need to prepare a cassette for each chemical size. As a result, a sheet sensor 130 which is less expensive than a non-contact type distance measuring device using laser or ultrasonic waves as used in the conventional apparatus is adopted, and the sheet sensor 130 is arranged along the storing direction X in the cassettes 100 to 100z. Since it is configured so as to extend in a sheet shape and press the sheet surface 130a of the sheet sensor 130 at the position P, the apparatus cost can be kept low with a relatively simple apparatus configuration. Since the storage unit 12a, the reading unit M1, and the calculation unit M2 are provided, the ampoule size S in the storage direction X of the ampoule 1 stored in the plurality of cassettes 100 to 100z is stored in advance in the storage unit 12a. The ampule size S stored in the storage unit 12a is read by the reading means M1, respectively, and the calculation means 2, the ampule row lengths d detected by the sheet sensors 130 of the plurality of cassettes 100 to 100 z are divided by the ampule size S respectively read by the reading means M <b> 1, thereby obtaining the plurality of cassettes 100 to 100 z. The stock quantity of the ampoule 1 to be stored can be obtained.

  Further, as the rolling members 144 to 144z, cylindrical members are adopted, and the rolling members 144 to 144z can make line contact with the sheet surface 130a, respectively, so that the sheet surface 130a can be reliably pressed by that amount. The detection accuracy of the sheet sensor 130 can be improved. Further, in the cassettes 100 and 100x, since the rolling members 144 and 144x are pressed against the sheet surface 130a by the rolling member urging members 145 and 145x, the sheet surface 130a can be pressed more reliably, and the sheet sensor 130 can be pressed. The detection accuracy can be further improved.

  The cassettes 100 to 100z are configured to detect the sheet sensor 130 at the positions of the rolling members 144 to 144z provided on the pressing members 140 to 140z. However, the ampule row 1a directly contacts the sheet surface 130a of the sheet sensor 130. You may comprise so that it may press. In this case, the sheet surface 130a of the sheet sensor 130 can be pressed at the position of the ampule 1 on the other side 1a "of the ampule row.
