[Configuration of Sample Distributing Part 1, Sample Preparing Unit 2, and Optical Detector 3]
As shown in FIG. 5, the urine (sample) in the test tube 32 is aspirated by a syringe pump (not shown) using an aspirate tube 17, and dispensed into the sample preparing unit 2 by the sample distributing part 1. The sample preparing unit according to the present embodiment is configured by a sample preparing part (first sample preparing part) 2 u and a sample preparing part (second sample preparing part) 2 b, and the sample distributing part 1 distributes the quantitated aliquot of the urine (sample) to each of the sample preparing part 2 u and the sample preparing part 2 b. The urine aliquot of the sample preparing part 2 u is mixed with a diluted solution 69 u and a stain solution (stain reagent) 68 u. The urine aliquot of the sample preparing part 2 u is then stained by the pigment contained in the stain solution (stain reagent) 68 u, so that the urine aliquot becomes a suspension for analyzing a relatively large particles such as red blood cells, white blood cells, epidermal cells, casts, and the like. The urine aliquot of the sample preparing part 2 b, on the other hand, is mixed with a diluted solution 69 b and a stain solution (stain reagent) 68 b. The urine aliquot of the sample preparing part 2 b is then stained by the pigment contained in the stain solution (stain reagent) 68 b, so that the urine aliquot becomes a suspension for analyzing bacteria.
Of the two types of suspensions (measurement samples) prepared as above, the suspension (first measurement sample) of the sample preparing part 2 u is first guided to the optical detector 3 forming a thin flow enveloped by sheath solution in a sheath flow cell 51, and irradiated with laser light. Thereafter, the suspension (second measurement sample) of the sample preparing part 2 b is similarly guided to the optical detector 3 forming a thin flow in the sheath flow cell 51, and irradiated with laser light. Such operations are automatically performed by operating the driving unit 17 etc. by the control of the measurement control unit 16 as hereinafter described.
FIG. 6 is a view showing a configuration of the optical detector 3. In the figure, a condenser lens 52 collects the laser light emitted from a semiconductor laser 53 serving as a light source on the sheath flow cell 51, and a light collecting lens 54 collects a forward scattered light of the particles in the urine on a photodiode 55 serving as a scattered light receiving part. Another light collecting lens 56 collects a lateral scattered light and a lateral fluorescence of the particles on a dichroic mirror 57. The dichroic mirror 57 reflects the lateral scattered light towards a photomultiplier 58 serving as a scattered light receiving part, and transmits the lateral fluorescence towards a photomultiplier 59 serving as a fluorescence receiving part. The optical signals reflect the characteristics of the particles in the urine. The photodiode 55, the photomultiplier 58, and the photomultiplier 59 convert the light signal to an electrical signal and respectively output a forward scattered light signal (FSC), a lateral scattered light signal (SSC), and a lateral fluorescence signal (SFL). The output is amplified by a preamplifier (not shown) and provided to the signal processing circuit 4 (FIG. 3).
The forward scattered light signal (FSC), the lateral scattered light signal (SSC), and the lateral fluorescence signal (SFL) processed in the signal processing circuit 4 are sent to the system controller 13 via the external communication controller 25 by the microprocessor 20. In the system controller 13, a scattergram for analyzing the particles in the urine is formed based on the forward scattered light signal (FSC), the lateral scattered light signal (SSC), and the lateral fluorescence signal (SFL), and using this scattergram, the particles in the sample is classified into red blood cells, white blood cells, epidermal cells, casts, bacteria and the like.
As for the light source, a gas laser may be used in place of the semiconductor laser, but the semiconductor laser is preferably used in terms of low cost, compactness, and low power consumption, so that the manufacturing cost can be reduced and miniaturization as well as power saving of the apparatus can be achieved through the use of the semiconductor laser. Among the semiconductor lasers, a red semiconductor laser is preferably used as it is low cost, has long lifespan, and supply from the manufacturing company is stable.

The sample is aspirated from the test tube 32 of the rack 31 arranged at the aspirating position by the sample aspirating part 10 a. After aspiration is terminated, the test tube 32 adjacent to the test tube 32, which sample has been aspirated, is then arranged at the aspirating position, and the sample of the test tube 32 arranged at the aspirating position is aspirated. The rack 31 is transported to the starting position 35 a of the rack accommodating region 35 when the aspiration of the sample from all the test tubes 32 accommodated in the rack 31 is terminated by repeating such operation. The rack 31 transported to the starting position 35 a is transported towards the terminating position 35 b on the near side as shown with an arrow (3). In this manner, all the racks 31 set in the rack set region 34 are accommodated in the rack accommodating region 35 when aspiration of the sample from all the test tubes 32 accommodated in the rack 31 is terminated.
[Type of Transporting Apparatus 11]
The transporting apparatus 11 has a plurality of types depending on the size etc. of the rack 31 to be transported. FIGS. 8( a) and 8(b) show transporting apparatuses 11X and 11W for transporting two types of racks 31 in which the number of test tubes 32 that can be held differs. The transporting apparatus 11X (hereinafter referred to as transporting apparatus X) of FIG. 8( a) is for the rack 31 (for ten-sample rack) for holding ten test tubes 32, and the transporting apparatus 11W (hereinafter referred to as transporting apparatus W) of FIG. 8( b) is for the rack 31 (for five-sample rack) for holding five test tubes 32.
The ten-sample rack used in the transporting apparatus X and the five-sample rack used in the transporting apparatus W will now be described. As shown in FIG. 9( a), the ten-sample rack 226 includes ten accommodating parts 211 for accommodating the test tube 32. As shown in FIG. 9( b), the ten-sample rack 226 includes ten concave parts 212 at the bottom surface. Each concave part 212 is arranged at a position corresponding to each accommodating part 211. As shown in FIG. 10, the five-sample rack 92 includes five accommodating parts 93 for accommodating the test tube 32 and one concave part 96 arranged at the center in the longitudinal direction of the bottom surface. The interval at which the accommodating position for accommodating the test tube 32 is arranged differs between the ten-sample rack 226 and the five-sample rack 92. That is, the distance T1 between the test tubes 32 accommodated in the accommodating part 211 of the ten-sample rack 226 and the distance T2 between the test tubes 32 accommodated in the accommodating part 93 of the five-sample rack 92 differ.
The transverse feeding operation for feeding the test tube 32 accommodated in the ten-sample rack 226 of the transporting apparatus X to the aspirating position facing the sample aspirating part 10 a will now be described. The transporting apparatus X includes a projection for engaging the concave part 212 of the ten-sample rack 226, a slide mechanism for moving the projection, and a stepping motor for driving the slide mechanism (not shown). The transporting apparatus X is formed with a transport surface for transporting the ten-sample rack 226, so that the ten-sample rack 226 moves on the transport surface. A cutout for projecting the projection is formed at the transport surface. The projection is at an initial position of the lower part of the transport surface adjacent to the cutout. The projection moves from the initial position and projects out from the cutout when the stepping motor is operated. The projected projection engages one of the ten concave parts 212 arranged at the bottom surface of the ten-sample rack 226, and the projection horizontally moves and feeds the ten-sample rack 226 transversely by one pitch when the stepping motor is operated. The transporting apparatus X also provides a pulse signal of the number of pulse for feeding one pitch to the stepping motor in accordance with the distance T1 between the test tubes 32 of the rack 226, whereby the rack 226 is fed by one pitch. When the test tube 32 is transported to the aspirating position facing the sample aspirating part 10 a, the sensor 37 a detects such transport and transmits a detection signal to the measurement control unit 16 (see FIG. 3). The test tube 32 is then arranged at the aspirating position. The projection is then disengaged from the concave part 212, and returned to the initial position by operating the stepping motor. The projection then engages the adjacent concave part 21 of the previously engaged concave part 212, and the projection horizontally moves and feeds the ten-sample rack 226 transversely by one pitch when the stepping motor is operated.
The transverse feeding operation for feeding the test tube 32 accommodated in the five-sample rack 92 of the transporting apparatus W (FIG. 8( b)) to the aspirating position facing the sample aspirating part 10 a will now be described. The transporting apparatus W includes a projection for engaging the concave part 96 of the five-sample rack 92, a movement belt for moving the projection, and a stepping motor for driving the movement belt (not shown). The transporting apparatus W is formed with a transport surface for transporting the five-sample rack 92, so that the five-sample rack 92 moves on the transport surface. A cutout for projecting the projection is formed at the transport surface. The projection is at an initial position of the lower part of the transport surface adjacent to the cutout. The projection moves from the initial position and projects out from the cutout when the stepping motor is operated. The projection engages one concave part 96 arranged at the bottom surface of the five-sample rack 92, and the projection horizontally moves and feeds the five-sample rack 92 transversely by one pitch when the stepping motor is operated. The transporting apparatus W also provides the number of pulse for feeding one pitch to the pulse motor in accordance with the distance T2 between the test tubes 32 of the rack 92, whereby the rack 92 is fed by one pitch. When the test tube 32 is transported to the aspirating position facing the sample aspirating part 10 a, the sensor 37 a detects such transport and transmits a detection signal to the measurement control unit 16 (see FIG. 3). The test tube 32 is then arranged at the aspirating position. When the stepping motor is operated while engaging the one concave part 96 arranged at the bottom surface of the five-sample rack 92, the projection horizontally moves and feeds the five-sample rack 92 transversely by one pitch. The projection is then disengaged from the concave part 96 when the five-sample rack 92 is fed by five pitches, and returned to the initial position by operating the stepping motor. The projection then engages the concave part 96 of the adjacent five-sample rack 92 of the five-sample rack 92 that has been transversely fed by five pitches, and horizontally moves and feeds the five-sample rack 92 transversely by one pitch when the stepping motor is operated.
As shown in FIG. 8, the transporting apparatus X for the ten-sample rack and the transporting apparatus W for the five-sample rack have substantially the same left-right width so as to correspond to the left-right width of the apparatus body 12 of the analyzer 10, but differs in the length in the front and back direction. The ten-sample rack transporting apparatus X and the five-sample rack transporting apparatus W differ in the transporting distance L11 and L12 of the rack 31 in the rack set region 34 and the rack accommodating region 35, and furthermore, the rack transporting distances L21 and L22 between the rack set region 34 and the rack accommodating region 35 as well as the feeding pitches P1 and P2 for feeding each test tube 32 to the aspirating position facing the sample aspirating part 10 a differ. As described above, the mechanism and the operation for transverse feeding each test tube 32 to the aspirating position differ between the transporting apparatuses X, W. Therefore, programs for operation controlling the transporting apparatuses X, W differ from each other.
The transporting apparatus 11 also has a plurality of types depending on whether or not a control unit for controlling the operation thereof is arranged. As shown in FIG. 3, the transporting apparatuses X, W described above include a transport driving part 36 a such as a stepping motor for transporting the rack 31 and a sensor 37 a such as a photosensor and a microswitch for detecting the position etc. of the rack 31 but do not include a control unit. Thus a transporting apparatus X controlling program and a transporting apparatus W controlling program are incorporated in the memory 21 to control the transporting apparatuses X, W from the measurement control unit 16 of the analyzer 10.
When the transporting apparatus controlling program is executed, the signal from the transport sensor 37 a is transmitted to the microprocessor 20 of the measurement control unit 16 via the sensor signal processing part 23 and the I/O controller 22. When the signal is transmitted, the microprocessor 20 transmits information for control to the driving unit control driver 24 via the I/O controller 22. The driving unit control driver 24 generates a control signal corresponding to the transmitted information, and transmits the control signal to the transport driving part 36 a to perform the control. Therefore, communication of the sensor signal and the control signal is performed between the measurement control unit 16 and the transporting apparatuses X, W.
The procedure for the communication between the measurement control unit 16 and the transporting apparatus X (ten-sample rack transporting apparatus) will now be specifically described with reference to FIG. 11. The microprocessor 20 (FIG. 3) of the measurement control unit 16 executes the transporting apparatus X program stored in the memory 21. The microprocessor 20 provides information such as rotation amount, rotating direction, speed, and the like of the pulse motor for horizontally moving (transverse feeding) the projection for transporting the ten-sample rack 226 to the driving unit control driver 24. The driving unit control driver 24 transmits the control signal to the transport driving part 36 a according to the received information. The transporting apparatus X receives the control signal, so that the transport driving part 36 a operates according to the control signal, and the ten-sample rack 226 is transported (transversely fed) so that the test tube 32 at the head of the ten-sample rack 226 is at the aspirating position facing the sample aspirating part 10 a. The sensor 37 a of the transporting apparatus X detects that the head test tube 32 has been transported to the aspirating position facing the sample aspirating part 10 a, and the detection signal is provided to the microprocessor 20 via the sensor signal processing part 23. The microprocessor 20 then controls the sample aspirating part 10 a so that the sample is aspirated from the test tube 32. The sample aspirating part 10 a then aspirates the sample from the test tube 32. When aspiration is terminated, the microprocessor 20 sends information such as rotation amount, rotating direction, speed, and the like of the pulse motor for performing the returning operation of returning the projection for transporting the ten-sample rack 226 to the initial position to the driving unit control driver 24. The driving unit control driver 24 transmits the control signal to the transport driving part 36 a according to the received information. The transporting apparatus X receives the control signal, so that the transport driving part 36 a operates according to the control signal and the projection is returned to the initial position. Such procedure is repeatedly carried out for all the test tubes 32 accommodated in the ten-sample rack 226.
The configuration of transporting apparatuses Y, Z will now be described. As shown in FIG. 3, the transporting apparatuses Y, Z include a transport driving part 36 b and a transport sensor 37 b. The transporting apparatuses Y, Z also include a control unit 38. The control unit 38 is arranged with an external communication controller 39, a microprocessor 40, and a memory 41. The external communication controller 39 is connected to the external communication controller 25 of the analyzer 10. When the transporting apparatuses Y, Z are connected, a communication program for communicating with the control units 38 of the transporting apparatuses Y, Z is executed in the measurement control unit 16 of the analyzer 10 to achieve cooperation of operation with the transporting apparatuses Y, Z. The transporting apparatuses Y, Z is generally used as one part of a transport system used for a plurality of analyzers in a large facility etc. The transport driving part 36 b is operation controlled by a control program incorporated in the memory 41 of the control unit 38.
When the transporting apparatuses Y, Z are connected to the analyzer 10, the communication is performed in the following manner. For example, when the transporting apparatus Y, Z transports the test tube 32 to the aspirating position facing the sample aspirating part 10 a, the information indicating the same is transmitted to the analyzer 10, and the analyzer 10 receives such information and performs the operation of aspirating the sample from the test tube 32. Subsequently, the analyzer 10 transmits information indicating that the sample has been aspirated to the transporting apparatus Y, Z, and the transporting apparatus Y, Z receives such information and performs the operation of transporting the next test tube 32 to the aspirating position facing the sample aspirating part 10 a. The procedure for communication between the transporting apparatus Y (ten-sample rack transporting apparatus) and the analyzer 10 will now be specifically described with reference to FIG. 12. The microprocessor 40 of the transporting apparatus Y executes the control program for controlling the operation of the transporting apparatus Y, and the microprocessor 20 of the apparatus body 12 executes the communication program for performing communication of the analyzer 10 and the transporting apparatus Y and the control program for controlling the operation of the analyzer 10. The microprocessor 40 of the transporting apparatus Y transports (feeds transversely) the ten sample rack 226 so that the head test tube 32 of the sample rack 226 comes to the aspirating position facing the sample aspirating part 10 a. The microprocessor 40 sends a measurement instruction signal instructing the start of measurement of the apparatus body 12 (or transport terminated signal indicating that transport is terminated) to the measurement control unit 16 of the analyzer 10. The microprocessor 20 of the apparatus body 12 receives the measurement instruction signal, and sends a prohibiting signal indicating the prohibition of the transverse feeding operation of the ten-sample rack 226 to the control unit 38 of the transporting apparatus Y. After transmitting the prohibiting information, the microprocessor 20 of the apparatus body 12 performs the operation of aspirating the sample from the test tube 32 (position 1) of the ten-sample rack 226 transversely fed to the aspirating position facing the sample aspirating part 10 a. When the aspirating operation is terminated, the microprocessor 20 sends a permitting signal indicating permission of transverse feeding operation of the ten-sample rack 226 (or aspirate terminated signal indicating that aspirating operation is terminated) to the control unit 38 of the transporting apparatus Y. The microprocessor 40 of the transporting apparatus Y feeds the ten-sample rack 226 transversely so that the next test tube 32 (position 2) of the ten-sample rack 226 comes to the aspirating position facing the sample aspirating part 10 a. Thereafter, the microprocessor 40 sends information on the measurement instruction to the measurement control unit 16. Such procedure is repeatedly performed for all the test tubes 32 accommodated in the ten-sample rack 226.
In the analyzer 10 of the present invention, all of the control program and the communication program (hereinafter collectively referred to as transporting apparatus program) corresponding to the type (X, Y, Z, W) of the transporting apparatus 11 as described above are incorporated in advance in the memory 21 of the measurement control unit 16. The analyzer 10 obtains the identification information indicating the type (X, Y, Z, W) of the connected transporting apparatus 11, and selects and executes the transporting apparatus program according to the identification information. The operation corresponding to any of the plurality of types of transporting apparatus 11 can then be performed.
That is, the analyzer 10 of the present invention includes an input means for inputting identification information for identifying the type of the transporting apparatus 11, and a control unit 16 for performing the operation (control or communication) with respect to the transporting apparatus 11 according to the identification information input by the input means.
In the present embodiment, the analyzer 10 has a configuration of inputting the identification information corresponding to the type (X, Y, Z, W) of the transporting apparatus 11 manually by the user through the input part 29 of the system controller (personal computer) 13, and selecting the transporting apparatus program to be executed by the measurement control unit 16 according to the input identification information.
FIG. 13 is a flowchart showing the procedures for setting the set value of each transporting apparatus X, Y, Z when the transporting apparatus 11 is connected to the analyzer 10. When the power (not shown) of the apparatus body 12 is turned ON, initialization of the measurement control unit 16 (initialization of the program) is performed in step S6, the operation check of each unit of the apparatus body 12 is performed, and the standby state is obtained. When the power (not shown) of the system controller 13 (personal computer) is turned ON, initialization of the system controller 13 (initialization of the program) is performed in step S1, and the log-in screen is displayed on the display 28. In the log-in screen, the user having the authority to set the transporting apparatus logs in (step S2), and the service icon for setting the transporting apparatus is displayed as hereinafter described. In step S3, the system controller 13 displays the standby screen (hereinafter described as operation screen W1).
As shown in FIGS. 14 to 17, the operation screens W1 to W4 includes a title bar B1, a menu bar B2, a tool bar B3, a function display region R, and a status bar B4. The title bar B1 displays name etc. of the operation screen W1 to W4, and the menu bar B2 displays the operation menu in the operation screen W1 to W4. The tool bar B3 displays a plurality of tool buttons (icons) TIC for executing various functions.
FIG. 14 shows the menu screen W1 of the operation program, and a plurality of function icons IC is displayed in the function display region R of the menu screen W1. Various measurements, settings, and the like are executed by selecting one of the function icons IC.
A controller icon IC1 of the menu screen W1 is selected to identify the type of transporting apparatus 11 connected to the analyzer 10.
FIG. 15 shows a controller screen W2 displayed when the controller icon IC1 (FIG. 14) is selected. A service icon IC2 is displayed in the function display region R of the controller screen W2. The service icon IC2 is an icon for calling up the function (service function) used in the installation of the analyzer 10 or the maintenance after the installation.
The service icon IC2 is displayed only when the user ID and the password input when operating the operation program and the operating system is recognized as those of a specific person. In other words, only the person having the authority to use the service function can use the function. Therefore, the service icon IC2 will not be displayed even if the user other than the person having the authority to use the service function logs into the system controller 13 and displays the controller screen W2. Thus, there is no possibility the setting of the service function will be changed etc. by the user by mistake.
FIG. 16 shows a service screen W3 displayed when the service icon IC2 (FIG. 15) is selected. The function icons IC related to various settings, tests, and maintenances are displayed in the function display region R of the service screen W3. The service setting icon IC3 of the service screen W3 is selected to identify the transporting apparatus 11 connected to the analyzer 10.
FIG. 17 is a service setting screen W4 displayed when the service setting icon IC3 (FIG. 16) is selected. A pull-down menu H1 for selecting the target of service setting, an item display window H2 for displaying setting items of the selected target, a selected item display part H3 for displaying the items selected in the item display window H2, an input field H4 for inputting the set values which are identification information of the transporting apparatus 11, and a set value display part H5 showing an example of a set value that can be input to the input field H4.
Various setting items are listed in the up and down direction in the item display window H2, and one of the items is a connection setting item (connection, sampler/transportation) H2 a of the transporting apparatus 11. When the item H2 a is selected, the relevant item name is displayed in the selected item display part H3. One of the set values displayed on the set value display part H5 can be input to the input field H4. In the present example, the set value of one of �0� to �4� can be input. Specific names etc. of the transporting apparatus 11 to be connected are displayed next to each set value �0� to �4� in the set value display part H5.
The relationship between the type (X, Y, Z, W) of the transporting apparatus 11 connected to the analyzer 10 and the set values �0� to �4� is as shown in FIG. 18. The set value �0� is the set value of �standard mode� selected when the transporting apparatus 11 is not connected to the analyzer 10. In this case, only manual measurement of supplying the sample to the analyzer 10 by hand can be performed.
The set value �1� is the set value of �transporting apparatus X mode� selected when the transporting apparatus 11 (transporting apparatus X shown in FIG. 8( a)) for the ten-sample rack is connected to the analyzer 10. The transporting apparatus X does not have a control unit, and is controlled by the measurement control unit 16 (FIG. 3) of the analyzer 10.
The set value �2� is the set value of �transporting apparatus Y mode� selected when the transporting apparatus 11 (Y) including the control unit 38 (FIG. 3) is connected to the analyzer 10. The set value �3� is the set value of �transporting apparatus Z mode� selected when the transporting apparatus 11 (Z) including the control unit 38 (FIG. 3) different from the transporting apparatus Y is connected to the analyzer 10.
The set value �4� is the set value of �transporting apparatus W mode� selected when the transporting apparatus 11 (transporting apparatus W shown in FIG. 8( b)) for the five-sample rack is connected to the analyzer 10. The transporting apparatus W does not have a control unit, and is controlled by the measurement control unit 16 (FIG. 3) of the analyzer 10. Therefore, in the present embodiment, the operation program to be executed by the system controller 13, the input part 29, and the like configure the input means for inputting the identification information of the transporting apparatus 11.
Returning to the flowchart shown in FIG. 13, the continuation of the procedure for setting the set values of the transporting apparatus will be described. In step S4, the system controller 13 determines whether or not the selection of the transporting apparatus is accepted, that is, whether or not the input of the set value �0� to �4� is made from the operation program of the system controller 13 as described above. If the set value is input, the system controller 13 transmits a signal corresponding to the relevant transporting apparatus to the measurement control unit 16 of the apparatus body 12 (step S5). The measurement control unit 16 determines whether or not the signal corresponding to the transporting apparatus is received (step S7), and if the relevant signal is received, stores the set value of the transporting apparatus corresponding to the signal in the memory 21 and terminates the process (step S8).
When the transporting apparatus 11 is connected to the analyzer 10, the measurement (manual measurement mode) for supplying the sample by hand without using the transporting apparatus 11 can be selectively carried out in addition to the measurement (transporting apparatus measurement mode) using the transporting apparatus 11. Specifically, as shown in FIG. 14, such measurements can be performed by selecting the transporting apparatus measurement icon ICa or the manual measurement icon ICb from the menu screen W1 displayed on the display 28 of the system controller (personal computer) 13.
FIG. 19 is a flowchart showing the procedures of when the analyzer 10 connected with the transporting apparatus 11 performs the transporting apparatus measurement mode. First, when the power (not shown) of the apparatus body 12 is turned ON, initialization of the measurement control unit 16 (initialization of the program) is performed in step S41, and the operation check of each unit of the apparatus body 12 is performed. The standby display is obtained when the indicator 6 shown in FIG. 1 is lighted green (step S42). When the power (not shown) of the system controller 13 (personal computer) is turned ON, the initialization of the system controller 13 (initialization of the program) is performed in step S61, and thereafter, the standby screen (menu screen W1: see FIG. 14) is displayed on the display 28 (step S62).
In step S63, when the user selects the transporting apparatus ICa of the standby screen (menu screen W1) displayed on the display 28, the system controller 13 transmits the measurement start signal to the measurement control unit 16 of the apparatus body 12 (step S64).
The measurement control unit 16 of the apparatus body 12 determines whether or not the start signal is received in step S43, and when the measurement start signal is received, reads out the transporting apparatus measurement program from the memory 21 in step S44, and reads out the transporting apparatus set value from the memory 21 (step S45). In step S46, the measurement control unit 16 determines what the transporting apparatus set value is (step S46). The measurement control unit 16 executes the transporting apparatus X program when the set value is �1�, (step S47 a), executes the transporting apparatus Y program when the set value is �2� (step S47 b), executes the transporting apparatus Z program when the set value is �3� (Step S47 c), and executes the transporting apparatus W program when the set value is �4� (step S47 d).
In step S48, the measurement control unit 16 transmits an operation state signal indicating that the apparatus body 12 is in the operation state to the system controller 13, and lights the indicator 6 shown in FIG. 1 to orange to indicate that the apparatus body 12 is in operation (step S49). In step S50, the measurement control unit 16 determines whether or not the measurement is completed, and returns the process to step S49 if the measurement is not completed. If the measurement is completed, the measurement control unit 16 transmits the measurement completed signal to the system controller 13 in step S51, and returns the process to step S42.
In step S65, the system controller 13 determines whether or not the operation state signal is received, and if the operation state signal is received, displays the display indicating �in measurement operation� on the display 28 (step S66). If the operation state signal is not received in step S65, the system controller 13 returns the process to step S62. The system controller 13 determines whether or not the measurement completed signal is received in step S67, and if the measurement completed signal is received, returns the process to step S62, and if the measurement completed signal is not received, returns the process to step S66.
If the instruction of measurement start is not made in step S63, the system controller 13 determines whether or not the instruction of shutdown is received in step S68. If the instruction of shutdown is not received in step S68, the system controller 13 returns the process to step S62. If the instruction of shutdown is received in step S68, the system controller 13 transmits a shutdown signal to the measurement control unit 16 (step S69).
If the measurement start signal is not received in step S43, the measurement control unit 16 determines whether or not the shutdown signal is received in step S52. If the shutdown signal is not received in step S52, the measurement control unit 16 returns the process to step S42. If the shutdown signal is received in step S52, the control unit 16 executes shutdown in step S53, and transmits a shutdown completed signal to the system controller 13 (step S54), and terminates the process.
The system controller 31 determines whether or not the shutdown completed signal is received in step S70, and repeats the process until the shutdown completed signal is received.
The transporting apparatus program includes a plurality of modules (components of program), that is, a common module common to all the transporting apparatus 11, and a dedicated module used according to each transporting apparatus. The measurement control unit 16 activates the common module, and selectively activates the dedicated module corresponding to the connected transporting apparatus to cause each transporting apparatus to perform the operation.
As described above, in the present embodiment, the transporting apparatus program corresponding to a plurality of types (X, Y, Z, W) of transporting apparatus 11 is stored in advance in the measurement control unit 16 of the analyzer 10, and the transporting apparatus program corresponding to the input identification information of the transporting apparatus 11 is executed by the measurement control unit 16. Thus, when the transporting apparatuses 11X, 11Y, 11W are connected to the analyzer 10, the transporting apparatus program corresponding to the type of the connected transporting apparatus does not need to be incorporated in the analyzer 10. Therefore, the setting task etc. involved in the connection of the transporting apparatus 11 can be simplified.
When the transporting apparatus 11 is equipped with the control unit, the communication program with the transporting apparatus 11 is executed, and when the transporting apparatus 11 is not equipped with the control unit, the control program of the transporting apparatus 11 is executed, whereby an appropriate operation can be performed on various types of transporting apparatuses 11.
The identification information of the transporting apparatus 11 is easily input from the input part 29 of the system controller 13. Furthermore, the input of the identification information by the input part 29 is made only by the person having the input authority, and the input by other users etc. is regulated, whereby false operation involved in the input of false identification information is prevented.
Second Embodiment The second embodiment of the present invention will now be described. As shown in FIG. 20, in the second embodiment, an identifying part 42 including the identification information for identifying the type is arranged in each transporting apparatus 11, and detection means 43 for detecting the identifying part 42 is arranged in the analyzer 10. The detection means 43 includes detection sensors 43A, 43B made of optical sensor, and the identifying part 42 is configured by a light shielding plate for light shielding the detection sensor 43.
The light shielding plate 42 is arranged in a projecting manner at the lower back part of the transporting apparatus 11, that is, a connection part to be connected with the apparatus body 12 of the analyzer 10. When the transporting apparatus 11 is connected to the apparatus body 12 of the analyzer 10, the light shielding plate 42 is inserted to the lower side (space S formed by supporting leg 14) of the apparatus body 12. The detection sensors 43A, 43B are arranged at the lower front part of the apparatus body 12, that is, the connection part 15 with respect to the transporting apparatus 11, so that the inserted light shielding plate 42 can be detected.
FIG. 21 is an explanatory view showing a relationship between the detection sensors 43A, 43B and the light shielding plate 42. In the present embodiment, four patterns of when three types of transporting apparatus 11 are connected and when the transporting apparatus 11 is not connected are identifiable. Specifically, two detection sensors (first, second sensors) 43A, 43B are arranged in the analyzer 10, and the light shielding plate 42 as shown in FIGS. 21( a) to 21(c) is arranged in each transporting apparatus 11. In the second embodiment, three types of X, Y, and Z are identified of the four types X, Y, Z, W (see FIG. 3 and FIG. 18) of transporting apparatuses 11 described in the first embodiment.
Two light shielding parts 42 a, 42 b for light shielding the detection sensors 43A, 43B are arranged in the light shielding plate 42 of the transporting apparatus X of FIG. 21( a). One light shielding part 42 a for shielding only the first detection sensor 43A is arranged in the light shielding plate 42 of the transporting apparatus Y of FIG. 21( b), and one light shielding part 42 b for light shielding only the second detection sensor 42B is arranged in the light shielding plate 42 of the transporting apparatus Z of FIG. 21( c).
The relationship between the type (X, Y, Z) of the transporting apparatus 11 connected to the analyzer 10 and the state and output of the first and second detection sensors 43A, 43B is as shown in FIG. 22. According to FIG. 22, when the transporting apparatus X is connected to the analyzer 10, both the first and second detection sensors 43A, 43B are light shielded (state of FIG. 21( a)), and both output becomes Low level. When the transporting apparatus Y is connected, the first detection sensor 43A is light shielded and the output thereof becomes Low level, but the second detection sensor 43B is not light shielded and is in an light incident state, and thus the output thereof becomes High level (state of FIG. 32 (b)). When the transporting apparatus Z is connected, the second detection sensor 43B is light shielded and the output thereof becomes Low level, but the first detection sensor 43A is not light shielded and is in an light incident state, and thus the output thereof becomes High level (state of FIG. 32( c)). When the transporting apparatus is not connected, both the first and second detection sensors 43A, 43B are not light shielded and are in an light incident state, and thus both output becomes High level.
Therefore, the combination of the outputs of the first and second detection sensors 43A, 43B differ depending on which transporting apparatus X, Y, Z to connect to the analyzer 10, and thus the type of the connected transporting apparatus 11 can be recognized by determining the combination of the outputs.
As shown in FIG. 23, the first and second detection sensors 43A, 43B are arranged in the apparatus body 12 of the analyzer 10. Configurations other than the first and second detection sensors 43A, 43B are the same as the configuration shown in FIG. 3, and thus the description thereof will be omitted. The output signals of the first and second detection sensors 43A, 43B are transmitted to the microprocessor 20 via the sensor signal processing part 23 and the I/O controller 22 of the measurement control unit 16.
FIG. 24 is a flowchart showing a procedure of when the analyzer 10 connected with the transporting apparatus 11 automatically identifies the type of the transporting apparatus, and performs the transporting apparatus measurement mode. The flow chart of FIG. 24 differs from the flowchart of FIG. 19 in steps S145 and S146, and steps S45 and S46, where step S47 d is not provided in the flowchart of FIG. 24, but other steps are the same between the flowchart of FIG. 24 and the flowchart of FIG. 19. As shown in FIG. 24, the measurement control unit 16 of the apparatus body 12 reads out the output signals of the detection sensors 43A, 43B in step S145, and determines the combination of the output signals of the detection sensors 43A, 43B (step S146). The measurement control unit 16 executes the transporting apparatus X program when the combination of the output signals of the detection sensors 43A, 43B is (Low, Low) (step S47 a), executes the transporting apparatus Y program when the combination of the output signals of the detection sensors 43A, 43B is (Low, High) (step S47 b), and executes the transporting apparatus Z program when the combination of the output signals of the detection sensors 43A, 43B is (High, Low) (step S47 c). Other processes are similar to the processes in the flowchart of FIG. 13.
As described above, in the second embodiment, the analyzer 10 stores the transporting apparatus program corresponding to a plurality of types (X, Y, Z) of transporting apparatuses 11 in advance in the measurement control unit 16, detects the identification information identifying the connected transporting apparatus 11, selects the transporting apparatus program corresponding to the detected identification information, and executes the relevant program. Thus, the transporting apparatus program does not need to be incorporated for each transporting apparatus 11 connected to the analyzer 10. Therefore, the setting task etc. involved in the connection of the transporting apparatus 11 can be simplified.
The detection of the identification information of the transporting apparatus 11 is performed by the detection sensor 43 by simply connecting the transporting apparatus 11 to the analyzer 10, and thus the setting task etc. involved in the connection of the transporting apparatus 11 can be further simplified.
