Description

Analysis equipment

The present invention relates to an analyzer for analyzing a sample, and more particularly, to an analyzer capable of taking in and out a container disposed in a housing of the analyzer.

As an analytical device for analyzing components of biochemical samples (blood, interstitial fluid, urine, spinal fluid, saliva, cells, etc.), a container is placed in the housing of the analytical device, and an analyzed sample (specimen) ) Is known (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 06-138132

In the analyzer as described above, in order to discard or sterilize the sample (specimen) accommodated in the container, it is necessary to take out the container to the outside of the housing. In response to such a request, a mechanism for pulling out the container in the housing to a predetermined take-out position is conceivable.

However, if the distance between the position of the container (the position where the sample is accommodated) in the housing and the take-out position becomes long, the amount of drawer (operation amount) of the drawer mechanism with respect to the housing may increase. Therefore, the user's labor and labor increase, and the usability of the analysis apparatus may decrease.

On the other hand, a method of suppressing the pulling amount of the pulling mechanism by setting the position of the container in the housing in the vicinity of the pulling position is also conceivable. However, the position of the container must be taken into consideration when determining the layout of the equipment (for example, equipment constituting the analysis device) accommodated in the housing, and the equipment may not be placed at a suitable position. There is.

The present invention has been made in view of the various circumstances as described above, and the object thereof is to improve the usability of the analyzer and layout in the casing when the container is disposed in the casing of the analyzer. Is to increase the degree of freedom.

In order to solve the above-described problem, the present invention provides an operation unit provided in a casing in an analyzer including a casing that houses the analyzing apparatus and a container that is disposed at a predetermined position in the casing. A mechanism for transporting the container from a predetermined position to a container take-out position in conjunction with the operation, and a mechanism for transmitting the transport mechanism by increasing the operation amount (operation amount) of the operation unit. did.

Specifically, the analyzer according to the present invention includes a housing that houses the analyzer, a container that is disposed at a predetermined position in the housing, and a container that is provided in the housing and that is placed in and out of the housing. An opening for performing the operation, an operation unit operated to take in and out the container through the opening, and the container is transported from the predetermined position to the container removal position in conjunction with the operation of the operation unit. A transport mechanism and a speed change mechanism that reduces an operation amount of the operation unit as compared with an amount by which the container moves from the predetermined position to the container removal position are provided.

Here, the “predetermined position” means a position where the container is arranged in the housing that houses the analyzer. Such a predetermined position varies depending on the type of analyzer and the like, and may be located in the center of the casing or may be positioned near the wall surface in the casing, and is particularly limited as long as it is in the casing. It is not something.

According to the analyzer configured in this way, the operation amount (operation amount) of the operation unit is smaller than the amount by which the container moves from the predetermined position to the container removal position. Therefore, even when the predetermined position is set at a position separated from the container take-out position, the container can be transported from the predetermined position to the container take-out position while suppressing the operation amount (operation amount) of the operation unit to be small. .

If the amount of operation (operation amount) of the operation unit is suppressed to be small, the user's labor and labor when putting in and out the container are reduced, so that the usability of the analyzer can be improved. In addition, when a predetermined position can be set at a location separated from the container take-out position, the number of options for the location where the predetermined position can be set increases, so the degree of freedom of layout in the housing is increased. For example, in an analyzer that optically measures a sample and accommodates the measured sample in a container, the measuring instrument and a predetermined position are placed in a location where the external light does not reach (for example, a location away from the opening) in the housing. It is possible to suppress a decrease in measurement accuracy by arranging.

Therefore, according to the analyzer according to the present invention, it is possible to increase the degree of freedom of the layout of the equipment accommodated in the housing while improving the usability of the analyzer. Note that the transport mechanism can transport the container in conjunction with the operation of the operation unit when transporting the container from the predetermined position to the predetermined position. It may be a mechanism that can.

As the operation unit according to the present invention, an operation unit that is provided at or near the opening and operates while projecting to the outside of the housing can be used. In this case, the transport mechanism may be a mechanism that transports the container from a predetermined position to a take-out position in conjunction with the protruding operation of the operation unit.

In the case where the operation unit and the transport mechanism are configured in this way, the amount of protrusion operation of the operation unit is smaller than the amount of movement of the container from the predetermined position to the container removal position. Therefore, even when the predetermined position is set at a position separated from the container take-out position, the amount of protrusion of the operation portion (the amount of protrusion to the outside of the housing) can be reduced.

¡If the amount of protrusion of the operation unit is reduced, the options for the location where the analyzer can be installed increase. Therefore, it is possible to increase the choices of places where the analyzer can be installed while enhancing the usability of the analyzer and the degree of freedom of layout in the housing.

As the speed change mechanism according to the present invention, it is possible to use a mechanism that increases the power of the operation unit and transmits it to the container when the operation unit operates. According to such a speed change mechanism, when the operation unit is operated, the amount of movement of the container increases with respect to the operation amount (operation amount) of the operation unit. As a result, it is possible to transport the container for a long distance while keeping the operation amount of the operation unit small.

As a mechanism for accelerating the power of the operation unit and transmitting it to the container, for example, a first belt that is looped between a pair of first pulleys and circulates in conjunction with the operation of the operation unit, and a pair of second pulleys. A mechanism comprising: a second belt that is looped around and circulates in conjunction with the movement of the container; and a transmission member that transmits the rotational force of the first pulley to the second pulley at a constant speed. A mechanism in which the diameter of one pulley is smaller than the diameter of the second pulley can be used.

According to such a mechanism, when the operation unit operates, the power of the operation unit is transmitted to the first pulley via the first belt. The rotational force of the first pulley is transmitted to the second pulley at a constant speed. The rotational force of the second pulley is transmitted to the container via the second belt. At this time, since the diameter of the first pulley is smaller than the diameter of the second pulley, the circulation amount of the second belt is larger than the circulation amount of the first belt. As a result, the power of the operation unit is transmitted to the container after being accelerated by the speed change mechanism.

It should be noted that a chain sprocket can be used instead of the first pulley and the second pulley, and a chain can be used instead of the belt.

Other configurations of the mechanism for accelerating the power of the operation unit and transmitting it to the container include, for example, a first gear that rotates in conjunction with the operation of the operation unit and a first gear that meshes with the first gear and moves the container And a second gear that rotates in conjunction with the first gear, wherein the first gear has a larger diameter than the second gear.

According to such a mechanism, when the operation unit operates, the first gear is rotated by the power of the operation unit. The rotational force of the first gear is transmitted to the second gear. At this time, since the diameter of the first gear is formed larger than the diameter of the second gear, the rotation amount of the second gear is larger than the rotation amount of the first gear. As a result, the power of the operation unit is transmitted to the container after being accelerated by the speed change mechanism.

If the power of the operation unit is increased and transmitted to the container, the posture of the container may become unstable when the operation speed of the operation unit increases. In particular, in a configuration in which the operation unit is manually operated, when the operation unit is vigorously operated, the container conveyance speed becomes rapid, and thus the posture of the container is likely to be unstable.

On the other hand, a mechanism for increasing the friction of the operation unit or a mechanism for increasing the friction of the transport mechanism may be added to suppress the rapid operation of the operation unit and the transport mechanism. As a mechanism for increasing the friction, a bush arranged so as to be in contact with a rotating shaft of a pulley or a gear, a hydraulic damper installed between the operation unit or the transport mechanism and the housing can be used.

As the operation unit according to the present invention, a mechanism that opens and closes the opening described above, and an open / close door that opens while projecting toward the outside of the housing can be used. In that case, the container can be moved in conjunction with the opening / closing operation of the door. For example, when the door is manually opened and closed, the user can open and close the door and move the container in one motion, so that usability is further improved.

As the open / close door as described above, a drawer-type open / close door that is slidably attached to the housing or a rotary open / close door that is rotatably attached to the housing can be used. .

The present invention is also suitable for an analysis system in which a plurality of analysis devices are accommodated in one housing. In that case, the present invention is an analysis system comprising a plurality of analyzers and a casing that houses the plurality of analyzers, the container disposed in the casing, and a wall surface of the casing An opening provided to put the container in and out of the housing, an operation part operated to take in and out the container through the opening, and the container in conjunction with the operation of the operation part A transport mechanism that transports the container from the predetermined position to the container removal position, and a speed change mechanism that reduces the amount of operation of the operation unit compared to the amount by which the container moves from the predetermined position to the container removal position. Also good.

According to the analysis system configured as described above, the operation amount of the operation unit can be reduced when taking out the container. Therefore, usability of the analysis system is increased. Further, since the predetermined position does not need to be set in the vicinity of the container take-out position, the number of places where the predetermined position can be set increases. As the number of places where the predetermined position can be set increases, the number of layout options that can be taken by a plurality of analyzers and the number of layout options that can be taken by the devices constituting each analyzer increase accordingly. As a result, it is possible to adopt a layout with high usability.

Note that the speed change mechanism according to the present invention is applicable to any device or system in which a container disposed in the casing needs to be taken in and out of the casing. In that case, the choice of a place where the housing can be installed increases, and the degree of freedom in layout of devices and the like accommodated in the housing can be increased.

The present invention can also be understood as a method for taking in and out a container arranged in a housing. For example, the present invention relates to a container insertion / removal method in which a container disposed at a predetermined position in the housing is taken in and out of the housing from an opening provided in the housing with respect to the housing that houses the analyzer. A step of transporting the container from the predetermined position to a container removal position in conjunction with an operation of an operation unit operated to remove the container through the opening. May be a method in which the operation amount of the operation portion is reduced compared to the amount of movement from the predetermined position to the container removal position. In other words, the present invention may be a method for putting in and out a container that transmits the operation portion at an increased speed.

According to such a method, when the container is taken out from the housing, the amount of operation of the operation unit can be suppressed to be small, so that the user's labor can be reduced. Furthermore, since there is no need to place the predetermined position in the vicinity of the container take-out position, there are more options for places where the predetermined position can be set. Thereby, it is also possible to increase the degree of freedom of layout of devices and the like housed in the housing.

According to the present invention, in the case where the container is arranged in the casing of the analyzer, the usability of the analyzer can be improved and the degree of freedom of layout in the casing can be increased.

<Example 1>
First, a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view showing the external appearance of the analyzer 1. FIG. 2 is a cross-sectional view illustrating a schematic configuration of the analyzer 1. The analyzer 1 is housed in a housing (housing) 11. The housing 11 is provided with a rack installation unit 13, a display panel 111, an operation switch group 112, a printer 113, and the like. Inside the housing 11, a test strip supply unit 12, a test strip transport device 14, a sample spotting device 15, a photometric device 16, a waste box 17, a waste box transport mechanism 19 and the like are accommodated.

The operation switch group 112 is various switches for the user (user) to operate the analyzer 1. For example, a power switch for switching on / off the main power of the analyzer 1, a sample analysis process (measurement process) A measurement start switch for starting, a print switch for causing the printer 113 to print the analysis result of the sample by the analyzer 1, and the like.

The display panel 111 includes, for example, an LCD (liquid crystal display) or a light emitting diode, and displays various information (for example, measurement results) according to the operation of the operation switch group 112.

The rack installation unit 13 is a unit in which a sample rack for standing and holding a plurality of sample containers containing urine as a sample is installed. The rack installation unit 13 is configured to be able to move the sample rack installed in the rack installation unit 13 within a horizontal plane in the rack installation unit 13.

The test strip supply unit 12 is a unit that stores the test strip 2 before use and supplies the stored test strip 2 to the test strip transport device 14 one by one. Specifically, the test strip supply unit 12 includes a hopper 121 that houses the test strip 2 in which one or a plurality of reagent pads are provided on a strip-shaped base material, and the test strip 2 from the hopper 121 one by one. A rotating drum 122 for taking out, and a pair of guides 123 for moving the test pieces 2 taken out by the rotating drum 122 to the test piece transporting apparatus 14 one by one are provided.

An opening / closing lid 1211 is provided in the upper opening of the hopper 121, and the inside and outside of the hopper 121 are partitioned by the opening / closing lid 1211. The rotating drum 122 has a recess 1221 that allows only one test piece 2 to be fitted on the outer peripheral surface thereof. The test piece 2 fitted in the recess 1221 by the rotation of the rotating drum 122 is transferred to the outside of the hopper 121 and then put into the pair of guides 123. The test piece 2 put into the pair of guides 123 is transferred to the test piece transport device 14.

The test strip transport device 14 transports the test strip 2 supplied from the test strip supply unit 12 to a position where the sample spotting device 15 can spot a sample (hereinafter referred to as “spotting position”). Furthermore, the test strip transport device 14 moves the test strip 2 after spotting the sample to a position where the photometry device 16 can perform photometry (hereinafter referred to as “photometry position”), and the test strip 2 after photometry (analysis). Drop the finished test piece 2) into the waste box 17. The test strip supply unit 12 is, for example, a mechanism that includes a plurality of recesses 141 that allow only one test strip 2 to be inserted, and sequentially feeds the test strips 2 supplied to the recesses 141 to the adjacent recesses 141. .

The sample spotting device 15 is a device for spotting urine on the reagent pad of the test piece 2. The sample spotting device 15 includes a nozzle 151 and a nozzle driving unit 152 for moving the nozzle 151. The nozzle 151 is supported by the arm of the nozzle driving unit 152 and can move in the vertical direction and the horizontal direction in the housing 11. The nozzle drive unit 152 can be configured using an actuator such as a reciprocating cylinder or an appropriate drive means such as a circulation drive belt. The nozzle 151 sucks urine from the sample container held by the sample rack 131 and drops urine onto each reagent pad of the test piece 2 transferred to the spotting position by the test piece transport device 14, that is, spotted.

The photometry device 16 receives the reflected light when the reagent pads of the test piece 2 on which the sample is spotted by the sample spotting device 15 is irradiated with light, and the degree of coloring (coloration) of each reagent pad This is a device for obtaining information according to (reaction). The photometric device 16 includes a light emitting unit 161 and a light receiving unit 162. The photometric device 16 is provided so as to be capable of reciprocating along the longitudinal direction of the test piece 2 at the photometric position, for example. The light emitting unit 161 can emit light having a specific peak wavelength, for example, and can be configured by a light-emitting diode (LED), a semiconductor laser, or the like. On the other hand, the light receiving unit 162 is for receiving light reflected from each reagent pad on which a sample is spotted, and can be configured by, for example, a photodiode.

The disposal box 17 is a box for storing the test piece 2 (that is, the analyzed test piece 2) after the photometry by the photometry device 16, and corresponds to a container according to the present invention. The disposal box 17 is supported by a holder 18 installed in the disposal box transport mechanism 19. The holder 18 is a support member for holding the disposal box 17 upright.

The disposal box transport mechanism 19 is a mechanism for transferring the holder 18 from the predetermined position P1 to the position P2. The predetermined position P1 described above is a position where the test strip 2 that has been analyzed by the test strip transport device 14 is dropped. The take-out position P <b> 2 is a position where the waste box 17 can be taken out of the housing 11, and is defined in the vicinity of the opening 200 provided on the side surface of the housing 11. In this figure, the take-out position P2 is located outside the housing 11, but the present invention is not limited to such an embodiment. That is, the take-out position P <b> 2 may be a position where the disposal box 17 can be taken out of the housing 11, and may be located inside the housing 11.

Note that the casing 11 is provided with a door 114 for opening and closing the opening 200 described above. The door 114 of this embodiment is a drawer-type opening / closing door (hereinafter referred to as “drawer door”) that opens while projecting horizontally from the side surface of the housing 11. The waste box transport mechanism 19 transports the holder 18 in conjunction with opening and closing of the drawer door 114. In other words, the waste box transport mechanism 19 transports the holder 18 using power for opening and closing the drawer door 114.

A handle 115 for pulling out (opening) the drawer door 114 is attached to the drawer door 114, and the user can pull out (open) the drawer door 114 using the handle 115. Yes. The drawer door 114 may be opened and closed using electric power, hydraulic pressure, or the like.

By the way, in the configuration in which the disposal box transport mechanism 19 moves the holder 18 in conjunction with the opening / closing operation of the drawer door 114, when the holder 18 and the drawer door 114 are directly connected, the drawer amount of the drawer door 114 is predetermined. This is equivalent to the distance between the position P1 and the take-out position P2. Therefore, as shown in FIG. 2, when the distance between the predetermined position P1 and the take-out position P2 becomes long, the pull-out amount of the pull-out door 114 (the amount protruding from the side surface of the housing 11) becomes excessive, and the analyzer 1 There is a problem that the installation location is limited.

For such a problem, a method of setting the predetermined position P1 in the vicinity of the extraction position P2 can be considered. However, when the predetermined position P1 is set in the vicinity of the take-out position P2, there is a possibility that the degree of freedom of the layout of the devices accommodated in the housing 11 is lowered. For example, there is a possibility that the arrangement of the photometric device 16 is limited to the vicinity of the take-out position P2 similarly to the predetermined position P1. In that case, there is a possibility that external light may leak from the opening 200, which may reduce the measurement accuracy of the photometric device 16. Although a method of separating the position of the photometric device 16 from the predetermined position P1 is conceivable, the path for transporting the test piece 2 after the photometry by the photometric device 16 from the vicinity of the photometric device 16 to the predetermined position P1 becomes longer. Therefore, there is a possibility that the test piece transport device 14 is increased in size.

Therefore, in this embodiment, the waste box transport mechanism 19 is configured so that the power for opening and closing the drawer door 114 is increased and transmitted to the holder 18. Hereinafter, a specific configuration of the disposal box transport mechanism 19 will be described with reference to FIGS. 3 to 6.

3 and 4 are side views of the disposal box transport mechanism 19. 3 shows a state in which the drawer door 114 is closed, and FIG. 4 shows a state in which the drawer door 114 is opened. The waste box transport mechanism 19 includes a guide rail 190 that slidably supports the holder 18 between a predetermined position P1 and a take-out position P2, and a first belt 194 spanned between the pair of first pulleys 193. , And a second belt 196 stretched between a pair of second pulleys 195.

The guide rail 190 is configured to be stretchable along a virtual straight line connecting the predetermined position P1 and the take-out position P2. Specifically, the guide rail 190 is configured by fitting two

rails

191 and 192 in a nested manner as shown in FIG. Of the two

rails

191 and 192, one rail 191 is fixed to the housing 11, and the other rail 192 is fixed to the drawer door 114. That is, the guide rail 190 expands and contracts with the opening / closing operation of the drawer door 114.

The two

rails

191 and 192 are formed with

guide grooves

191a and 192a that are continuous on the same straight line. The

guide grooves

191a and 192a penetrate from the upper surface to the lower surface of the

rails

191 and 192, and protrusions 18b provided on the lower surface of the holder 18 are inserted into the

guide grooves

191a and 192a (FIG. 6). See). That is, the holder 18 can slide on the guide rail 190 along the

guide grooves

191a and 192a.

3 and 4, the protrusion 18 b of the holder 18 is connected to the second belt 196, and the holder 18 moves together with the second belt 196 when the second belt 196 rotates. ing. A protrusion 114 a is also formed on the lower surface of the drawer door 114. The protrusion 114a of the drawer door 114 is connected to the first belt 194. When the drawer door 114 is opened and closed, the first belt 194 rotates in conjunction with the drawer door 114.

One of the first pulley 193 and one of the second pulley 195 are fixed to the same rotation shaft, and the first pulley 193 and the second pulley 195 rotate at a constant speed. However, the diameter of the first pulley 193 is smaller than the diameter of the second pulley 195. Therefore, the amount that the second belt 196 circulates per one rotation of the second pulley 195 is larger than the amount that the first belt 194 circulates per one rotation of the first pulley 193.

According to the waste box transport mechanism 19 configured in this way, the pull-out amount of the drawer door 114 is smaller than the amount of movement of the holder 18 and the waste box 17 from the predetermined position P1 to the pick-up position P2. The ratio between the diameter of the first pulley 193 and the diameter of the second pulley 195 is such that the end face of the holder 18 (the face located on the right side in FIGS. 3 and 4) when the holder 18 reaches the take-out position P2. Is preferably set so as to contact the drawer door 114. In that case, the waste box 17 can be taken out while minimizing the pull-out amount of the drawer door 114.

According to the embodiment described above, even when the predetermined position P1 is set at a position away from the take-out position P2, the holder 18 and the disposal box 17 are taken out while keeping the pull-out amount of the pull-out door 114 small. It can be moved to P2. As a result, the user's labor and time when taking out the disposal box 17 are reduced, so that the usability of the analysis system is improved. Furthermore, the degree of freedom in the layout of the devices accommodated in the housing 11 is increased, and the choices of places where the analyzer 1 can be installed increase.

The holder 18 may be provided with a closing plate 18a for closing the opening 200 of the housing 11 when the holder 18 is located at the take-out position P2. In that case, the inside and outside of the housing 11 can be partitioned even during the removal operation of the disposal box 17.

In this embodiment, the waste box transport mechanism 19 in which a pulley and a belt are combined is taken as an example, but a chain sprocket and a chain can be used instead of the pulley and the belt. Further, instead of the first pulley 193 and the first belt 194, a gear mechanism (rack and pinion) combining a pinion and a rack can be used. For example, the rack may be fixed to the drawer door 114 and the pinion gear may be fixed to the rotation shaft common to one second pulley 195.

In the present embodiment, the first pulley 193 and the second pulley 195 are fixed to the same rotation shaft, and the rotational force of the first pulley 193 is transmitted to the second pulley 195 at a constant speed as an example. However, it is also possible to use a configuration in which the rotational force of the first pulley 193 is increased and transmitted to the second pulley 195.

For example, as shown in FIG. 7, the first gear 193a rotating at the same speed as the first pulley 193, the second gear 195a rotating at the same speed as the second pulley 195, and the rotation of the first gear 193a as the second gear 195a. An intermediate gear 197 for transmitting to the gear mechanism, wherein the first gear 193a has a diameter larger than that of the intermediate gear 197, and the second gear 195a has a diameter smaller than that of the intermediate gear 197. Can be used.

According to such a gear mechanism, the rotation of the first gear 193a (first pulley 193) is increased by the intermediate gear 197, and the rotation of the intermediate gear 197 is further increased to increase the second gear 195a (second pulley 195). ). As a result, the rotational force of the first pulley 193 can be greatly increased and transmitted to the second pulley 195. This mechanism can be applied even when the diameter of the first pulley 193 and the diameter of the second pulley 195 are equal, and also when the diameter of the first pulley 193 is smaller than the diameter of the second pulley 195. be able to.

By the way, when the opening / closing operation of the drawer door 114 is accelerated and transmitted to the holder 18 and the disposal box 17 by various methods as described above, when the drawer door 114 is opened / closed vigorously, the holder 18 and Since the moving speed of the disposal box 17 becomes rapid, the posture of the disposal box 17 may become unstable. Therefore, a mechanism for increasing the friction of the waste box transport mechanism 19 may be added.

For example, as shown in FIG. 8, one end of the telescopic hydraulic damper 198 may be fixed to the housing 11 and the other end may be fixed to the drawer door 114. At this time, the magnitude of the resistance by the hydraulic damper 198 may be set to about 1 kgf. When the hydraulic damper 198 is provided in this manner, a situation in which the drawer door 114 is opened and closed vigorously is avoided, and a situation in which the holder 18 and the waste box 17 are rapidly moved along with this can be avoided. Even if the other end of the hydraulic damper 198 is fixed to the holder 18, the same effect can be obtained.

Also, by providing a mechanism for applying tension to the first belt 194 or the second belt 196, the friction of the waste box transport mechanism 19 can be increased. Furthermore, by providing a bush that rotatably supports at least one of the rotating shaft of the first pulley 193 and the second pulley 195, the rotational resistance of the rotating shaft can be increased.

<Example 2>
Next, a second embodiment of the present invention will be described with reference to FIGS. Here, a configuration different from that of the first embodiment described above will be described, and description of equivalent configurations will be omitted.

The difference between the first embodiment described above and the present embodiment is that the door that is opened and closed when the disposal box 17 is taken out is constituted by a rotary opening / closing door (hereinafter referred to as “rotating door”). It is in. 9 and 10 are side views of the waste box transport mechanism 19 in the present embodiment. 9 shows a state in which the pivot door is closed, and FIG. 10 shows a state in which the pivot door is opened.

9 and 10, the bottom of the door member formed in a flat plate shape is fixed to the support shaft 50. The support shaft 50 is supported by the housing 11 so as to be rotatable in the circumferential direction. When the handle 115b is pulled obliquely downward, the revolving door 114b configured in this way opens while rotating about the support shaft 50. In addition, the structure by which the upper part or side part is rotatably supported may be sufficient as the rotation door 114b.

Next, the waste box transport mechanism 19 of this embodiment includes a drive gear 51 attached to the support shaft 50, a driven gear 52 attached to the rotation shaft of one second pulley 195, the drive gear 51, and An intermediate gear 53 that meshes with the driven gear 52 and transmits the rotational force of the drive gear 51 to the driven gear 52. The drive gear 51 is formed larger in diameter than the intermediate gear 53, and the driven gear 52 is formed smaller in diameter than the intermediate gear 53.

According to the analyzer 1 configured as described above, the drive gear 51 rotates at the same speed as the support shaft 50 when the rotating door 114b is opened and closed. The rotational force of the drive gear 51 is transmitted to the intermediate gear 53. At this time, since the drive gear 51 is formed larger in diameter than the intermediate gear 53, the rotational force of the drive gear 51 is increased and transmitted to the intermediate gear 53.

Rotational force transmitted from the drive gear 51 to the intermediate gear 53 is transmitted to the driven gear 52. At this time, since the intermediate gear 53 is formed to have a diameter larger than that of the driven gear 52, the rotational force of the intermediate gear 53 is further increased and transmitted to the driven gear 52. The rotational force transmitted to the driven gear 52 is transmitted to the second pulley 195 at a constant speed.

Therefore, the rotational force of the rotating door 114b (in other words, the rotational force of the support shaft 50) is transmitted to the second pulley 195 after being accelerated by the gear mechanism. Therefore, the rotation amount of the second pulley 195 increases with respect to the rotation amount of the rotation door 114b (the rotation amount of the support shaft 50). As a result, even when the predetermined position P1 and the removal position P2 are separated from each other, the holder 18 and the disposal box 17 are moved from the predetermined position P1 to the removal position P2 (or moved from the removal position P2 to the predetermined position P1). It becomes possible to make it.

Note that one rail 192 of the guide rail 190 and the pivot door 114b are connected via a link mechanism 54, and the guide rail 190 is contracted and extended when the link mechanism 54 is bent and extended. It has become.

According to the embodiment described above, even if the opening / closing door is constituted by a rotary opening / closing door, the transportable distance of the holder 18 and the disposal box 17 can be extended. As a result, the usability of the analyzer 1 can be improved. Furthermore, the choice of the place where the analyzer 1 can be installed increases, and the degree of freedom of the layout of the equipment accommodated in the housing 11 increases.

In the present embodiment, the configuration in which the rotation amount of the support shaft 50 of the rotating door 114b is increased and transmitted to the holder 18 and the disposal box 17 is described as an example. A configuration in which the speed is increased and transmitted to the holder 18 and the disposal box 17 can also be adopted. For example, as shown in FIGS. 11 and 12, a pair of third pulleys 55 arranged in the vertical direction, a third belt 56 spanned between the third pulleys 55, and one third belt 56 are common. The structure provided with the gear 57 fixed to the rotating shaft and the arc-shaped gear 58 by which the flat tooth was provided in the internal peripheral surface of the circular-arc-shaped board | plate material can be illustrated.

At that time, the arc-shaped gear 58 is arranged so that one end of the arc-shaped gear 58 is fixed to the upper portion of the rotating door 114 b and the teeth of the arc-shaped gear 58 mesh with the gear 57. That is, the arc-shaped gear 58 moves in the circumferential direction while meshing with the gear 57 when the rotating door 114b rotates. Further, the other of the pair of third pulleys 55 is fixed to a rotation shaft common to the one second pulley 195, and the third pulley 55 and the second pulley 195 rotate at a constant speed. Further, the third pulley 55 is formed with a smaller diameter than the second pulley 195.

According to the configuration shown in FIGS. 11 and 12, when the pivot door 114b is opened and closed, the arc gear 58 moves in the circumferential direction (which can be said to be the direction in which the upper portion of the pivot door 114b rotates). To do. When the arcuate gear 58 moves in the circumferential direction, the gear 57 rotates accordingly. The rotational force of the gear 57 is transmitted to one third pulley 55 at a constant speed. The rotational force transmitted to one third pulley 55 is transmitted to the other third pulley 55 by the third belt 56 and then transmitted from the other third pulley 55 to the second pulley 195 at a constant speed. The rotational force of the second pulley 195 is transmitted to the holder 18 via the second belt 196.

Since the second pulley 195 is formed to be larger in diameter than the third pulley 55, the amount that the second belt 196 circulates per one rotation of the second pulley 195 and the third pulley 55 is the circulation amount of the third belt 56. Become more. Therefore, the configuration shown in FIGS. 11 and 12 can achieve the same effect as the configuration shown in FIGS.

<Application example>
In the first and second embodiments described above, an example in which one type of analysis device is accommodated in the housing 11 has been described. However, a multifunction machine in which a plurality of types of analysis devices are accommodated in the housing 11 is described. The present invention can also be suitably applied to (analysis system).

For example, as shown in FIG. 13, it is assumed that different analyzers 1a and 1b, which are different from each other, are accommodated on both sides of the analyzer 1 inside the housing 11. In such a case, since the distance from the predetermined position P1 to the take-out position P2 becomes longer, when the pull-out door 114 is used, the pull-out amount (protrusion amount) of the pull-out door 114 is further increased. There is a problem that the labor is increased and there are fewer choices of places where the analysis system can be installed. On the other hand, a method of changing the layout of the

analyzers

1, 1 a, 1 b can be considered, but layout options are limited, and usability may be reduced.

On the other hand, when the disposal box transport mechanism 19 as described in the first embodiment is applied, the disposal box 17 can be transported over a long distance while the pulling amount of the drawer door 114 is minimized. . As a result, it is possible to improve the usability of the analysis system, increase the choice of places where the analysis system can be installed, and improve the degree of freedom of the device layout accommodated in the housing 11. .

In the example shown in FIG. 13, a drawer door is used as the opening / closing door, but it is also possible to use a rotating door as described in the second embodiment.
