The analysis part 305 has a function of digitally image-processing the specimens of the stained slide glasses 10 while automatically classifying blood cells.
Operations of the specimen preparation/analysis system according to this embodiment are now described with reference to FIGS. 1 to 18.
As a sucking/dispensing operation, an operator presses the starting switch 102 to start the blood smear preparation apparatus 100, for setting the sample rack 150 storing the test tubes 151 storing blood samples on a receiving part 201 of the transporter 200, as shown in FIG. 1. Then, the operator presses a start switch for automatic suction displayed on the display operation part 101, for transporting the sample rack 150 to an unloading part 202 of the transporter 200. Thereafter the hand member 160 of the blood smear preparation apparatus 100 grasps one of the test tubes 151 storing blood from the sample rack 150. The hand member 160 moves up and rotates to lift up the test tube 151 and stir the contents thereof, and thereafter arranges the test tube 151 on the sucking/dispensing mechanism part 1 shown in FIG. 3. The sucking/dispensing mechanism part 1 inserts the piercer 1a into the rubber stopper 151a of the test tube 151 for sucking the blood. In this suction, the valves 1d and 1e are opened (on) and blocked (off) respectively. After completion of this suction, the valves 1d and 1e are blocked (off) and opened (on) respectively. Thereafter the pipette 1b is moved to the dispensing/smearing position 20 shown in FIG. 3.
In parallel with the sucking/dispensing operation, the cassettes are introduced with the cassette storage part 4 shown in FIG. 3. More specifically, the cassettes 3 are first set on the cassette storage part 4. Thus, the feeding belt 4a of the cassette storage part 4 engages with the transport belt engaging parts 3g (see FIGS. 5 and 6) of the cassettes 3, for feeding the same into a cassette standby position 40. The first one of the cassettes 3 fed into the cassette standby position 40 is arranged on the transport path 5c. 
At a step S1 of a flow chart shown in FIG. 18, the control part 110 of the blood smear preparation apparatus 100 acquires specimen information from the host computer 400 (see FIG. 2). This specimen information includes information such as sample numbers and the number of prepared smears etc. The specimen information also includes information as to whether to prepare either or both of visually recognized and automatically analyzed specimens etc. The specimen information further includes information as to whether or not to analyze the specimens in the automatic blood cell analyzer 300. At a step S2, the control part 110 calls smear conditions from a database stored therein. In the smear conditions for preparing smears, the volume of dropped blood, the angle of the draw glass 2c, the traveling speed of the draw glass 2c etc. have been previously set in correspondence to desired smears. At a step S3, the blood is dropped on (dispensed to) each slide glass 10 with the pipette 1b. In order to prepare both of automatically analyzed and visually recognized specimens, the sucking/dispensing apparatus 1 dispenses the same blood to two slide glasses 10 with the pipette 1b. In this case, the sucking/dispensing apparatus 1 dispenses the blood in a volume corresponding to the automatically analyzed specimen for preparing the automatically analyzed specimen, while dispensing the blood in a volume corresponding to the visually recognized specimen for preparing the visually recognized specimen.
At a step S4, the smearing part 2 smears the blood on the basis of the smear conditions in parallel with or after the aforementioned sucking/dispensing operation by the sucking/dispensing mechanism part 1. As shown in FIG. 3, the smearing part 2 supplies the slide glasses 10 to the dispensing/smearing position 20, for smearing the blood dropped on the slide glasses 10, drying the same and printing information on the slide glasses 10. More specifically, the unloading mechanism (not shown) and the feeding belts 2e supply the slide glasses 10 stored in the two slide glass storage parts 2b of the slide glass supply part 2a onto the feeding belts 2e. Then, the feeding belts 2e transport the slide glasses 10 to the dispensing/smearing position 20. The slide glasses 10 have been transported to the dispensing/smearing position 20 before the aforementioned sucking/dispensing operation. In this state, the sucking/dispensing mechanism part 1 drops (dispenses) the blood on (to) the slide glasses 10 with the pipette 1b. 
Thereafter the draw glass 2c moves to come into contact with the slide glasses 10 and reciprocates longitudinally along the slide glasses 10, thereby smearing the slide glasses 10 with the blood dropped thereon on the dispensing/smearing position 20. At this time, the contact angle of the draw glass 2c with respect to the slide glasses 10 and the speed of reciprocation thereof are varied with the automatically analyzed and visually recognized specimens. More specifically, the angle and the speed are so regulated that the automatically analyzed specimens are smaller in thickness than the visually recognized specimens. Thereafter the feeding belts 2e transport the smeared slide glasses 10 to the drying positions 21a. Then, the fan 2f dries the blood smeared on the slide glasses 10 with cold air on the two adjacent drying position 21a and 21b twice. Thereafter the slide glass transport part 2h moves the smeared slide glasses 10 to the printing part 2g. The smearing part 2 prints the two-dimensional bar code 10b storing the specimen information such as the sample number, the date, the serial number and the name and the three rows of texts 10c formed by Chinese characters of the date and the name etc. on the frosted part 10a of each slide glass 10 on the printing part 2g. 
Then, the cassette transport part 5 transports the cassettes 3 arranged on the transport path 5c one by one to the slide glass insertion part 6. In other words, the cassette transport member 5a constituting the cassette transport part 5 moves from the transport starting position 50 while pressing the side face parts 3h (see FIGS. 5 and 6) of the cassettes 3, thereby transporting the cassettes 3 to the slide glass insertion part 6.
At a step S5, the cassette transport part 5 stores the smeared slide glasses 10 in the cassettes 3 and transports the same to the staining part 7 with the cassette transport member 5a for staining the slide glasses 10.
More specifically, the cassette rotation mechanism part 6a rotates in a prescribed direction for moving the cassettes 3 from a vertical position to a horizontal position shown by two-dot chain lines in FIG. 3, to be capable of receiving the slide glasses 10. In this state, the vertical mover 2j of the smearing part 2 advances for inserting the smeared slide glasses 10 into the slide glass receiving holes 3a of the cassettes 3. Thus, the cassettes 3 store the smeared slide glasses 10. Thereafter the cassette rotation mechanism part 6a rotates oppositely to the aforementioned prescribed direction, thereby returning the cassettes 3 to the original vertical position. In the staining part 7, the first sucking/discharging part 7c lifts up the smeared slide glasses 10 from the slide glass storage holes 3a of the cassettes 3 for dispensing methanol to the stain sucking/dispensing holes 3b of the cassettes 3. Then the staining part 7 returns the smeared slide glasses 10 to the cassettes 3, so that the feed member 7a places the cassettes 3 storing the smeared slide glasses 10 one by one on the transport belts 7b. The transport belts 7b transport the cassettes 3 to the second sucking/discharging part 7d. 
The second sucking/discharging part 7d lifts up the smeared slide glasses 10 from the slide glass receiving holes 3a of the cassettes 3 and dries the same by applying a blast from the fan 7j to the smeared faces of the slide glasses 10 for about 1 second to about 60 seconds, thereby evaporating the liquid component on the smeared faces and drying the smeared faces. The time (dipping time) for dipping the smeared slide glasses 10 in methanol with the first sucking/discharging part 7c and lifting up the same with the second sucking/discharging part 7d is about 20 seconds to about 120 seconds.
Then, the staining part 7 performs staining (May-Grünwald/Giemsa double staining). First, the second sucking/discharging part 7d sucks methanol from the stain sucking/dispensing holes 3b of the cassettes 3, discharges the same, and thereafter returns the slide glasses 10 to the slide glass receiving holes 3a of the cassettes 3. Then, the staining part 7 dispenses May-Grünwald stain (mainly composed of 99% of methanol) through the stain sucking/dispensing holes 3b of the cassettes 3 and dips the smeared slide glasses 10 in the May-Grünwald stain. Thus, the staining part 7 starts May-Grünwald/Giemsa double staining. The staining part 7 dips the smeared slide glasses 10 in the May-Grünwald stain for about 1 minute to about 5 minutes while transporting the cassettes 3 with the transport belts 7b. The third sucking/discharging part 7e sucks the May-Grünwald stain from the stain sucking/dispensing holes 3b of the cassettes 3, discharges the same, and thereafter dispenses diluted May-Grünwald stain to the stain sucking/dispensing holes 3b of the cassettes 3. The staining part 7 dips the smeared slide glasses 10 in the diluted May-Grünwald stain for about 1 minute to about 5 minutes while transporting the cassettes 3 with the transport belts 7b. The fourth sucking/discharging part 7f sucks the diluted May-Grünwald stain from the stain sucking/dispensing holes 3b of the cassettes 3, discharges the same, and thereafter dispenses diluted Giemsa stain to the stain sucking/dispensing holes 3b of the cassettes 3. The staining part 7 dips the smeared slide glasses 10 in the diluted Giemsa stain for about 1 minute to about 20 minutes while transporting the cassettes 3 with the transport belts 7b. 
Then, the fifth sucking/discharging part 7g sucks the diluted Giemsa stain from the stain sucking/dispensing holes 3b of the cassettes 3, discharges the same, and thereafter dispenses and sucks a cleaning fluid to and from the stain sucking/dispensing holes 3b of the cassettes 3 for washing the smeared slide glasses 10. Thereafter the staining part 7 dries the stained slide glasses 10 with the fan 7h. 
At a step S6, the control part 110 turns on the cassette sensor 87 of the cassette detection part 8c of the second cassette transport part 8, thereby calling the specimen information from the database stored in the control part 110. More specifically, the cassettes 3 storing the stained slide glasses 10 are transported from the smearing part 7 to the transport starting position 80 of the second cassette transport part 8. At this time, each cassette 3 presses the bent part 88a of the detector 88 of the cassette detection part 8c outward beyond the frame 8a, as shown in FIG. 13. Thus, the detection part 88b of the detector 88 moves outward beyond the frame 8a, thereby turning on the cassette sensor 87. Consequently, the control part 110 calls the specimen information from the database stored in the memory 111 thereof.
At a step S7, the control part 110 decides the destination of the cassettes 3 storing the stained slide glasses 10 on the basis of the specimen information. In other words, the control part 110 decides whether to transport the cassettes 3 to the port 9a of the keeping part 9 of the blood smear preparation apparatus 100 or to the inlet 300a of the automatic blood cell analyzer 300.
At a step S8, the second transport part 8 transports the cassettes 3 storing the stained slide glasses 10 to the decided destination on the basis of information on the destination decided in the control part 110. More specifically, the drive motor 86 drives the driving belt 84 thereby moving the moving member 81 coupled to the driving belt 84 along arrow C, as shown in FIG. 10. Thus, the contact parts 81a and 81b of the moving member 81 come into contact with the side face parts 3h and 3j of the cassettes 3 respectively. Consequently, the contact parts 81a and 81b of the moving member 81 press and move the cassettes 3 along arrow C. At this time, the cassettes 3 move along the transport paths 8d and 8e arranged on the prescribed region in the blood smear preparation apparatus 100 and at the inlet 300a of the automatic blood cell analyzer 300 respectively.
According to this embodiment, the control part 110 controls the pulse number of the drive motor 86 on the basis of the decided destination information. More specifically, the control part 110 controls the movement of the moving member 81 along arrow C for completing movement of the cassettes 3 along arrow C on the port 9a as shown in FIG. 14, in order to transport the cassettes 3 storing the stained slide glasses 10 to the port 9a (see FIG. 3) of the keeping part 9 of the blood smear preparation apparatus 100. In order to transport the cassettes 3 storing the stained slide glasses 10 to the inlet 300a (see FIG. 3) of the automatic blood cell analyzer 300, on the other hand, the control part 110 controls the movement of the moving member 81 along arrow C for completing movement of the cassettes 3 along arrow C on the inlet 300a, as shown in FIG. 15. The second cassette transport part 8 transports the cassettes 3 in this manner, thereby terminating the operation flow shown in FIG. 18.
Then, the feed part 9b of the keeping part 9 moves the cassettes 3 storing the stained slide glasses 10 transported to the port 9a of the keeping part 9 of the blood smear preparation apparatus 100 toward the keeping part 9, as shown in FIG. 3. More specifically, the drive motor 96 rotates to drive the driving belt 95, thereby rotating the swinging member 91 in the same direction as the drive motor 96 as shown in FIG. 17. Thus, the swinging section 91a of the swinging member 91 presses upper portions of the cassettes 3, thereby moving the cassettes 3 toward the keeping part 9 (see FIG. 3). The control part 110 controls this operation of the feed part 9b. Thereafter the transport belt 9c transports the cassettes 3 to the keeping part 9, which in turn keeps the cassettes 3, as shown in FIG. 3.
On the other hand, the feed part 301 presses the cassettes 3 storing the stained slide glasses 10 transported to the inlet 300a of the automatic blood cell analyzer 300 toward the cassette storage part 302, while the transport belts 302a transport the cassettes 3 to the cassette storage part 302. At this time, the feed part 301 of the automatic blood cell analyzer 300 operates similarly to the feed part 9b of the keeping part 9. Thereafter the slide glass unloading part 303 unloads the stained slide glasses 10 from the cassettes 3 and transports the same to the bar code reading part 304. Then, the bar code reading part 304 reads the two-dimensional bar codes 10b printed on the frosted parts 10a of the slide glasses 10. The bar code reading part 304 transmits the read sample numbers of the stained slide glasses 10 to the control part 306, which in turn inquires the sample numbers from the host computer 400. Thus, the control part 306 confirms whether or not the stained slide glasses (specimens) 10 must be analyzed before transporting the same to the analysis part 305. If the stained slide glasses (specimens) 10 must be analyzed, the analysis part 305 digitally image-processes the stained slide glasses (specimens) 10 while automatically classifying blood cells. Thereafter the stained slide glasses (specimens) 10 subjected to blood cell classification are stored in a magazine (not shown) for analyzed specimens. When no analysis is necessary, on the other hand, the stained slide glasses (specimens) 10 are not analyzed in the analysis part 305 but stored in the magazine (not shown) for analyzed specimens. The control part 306 controls the operations of the slide glass unloading part 303 and the analysis part 305.
According to this embodiment, as hereinabove described, the blood smear preparation apparatus 100 is provided with the second cassette transport part 8 for transporting the cassettes 3 storing the stained slide glasses (specimens) 10 to the inlet 300a of the automatic blood cell analyzer 300 so that the second cassette transport part 8 can automatically supply specimens from the blood smear preparation apparatus 100 to the automatic blood cell analyzer 300. Thus, the specimen preparation/analysis system can supply the specimens from the blood smear preparation apparatus 100 to the automatic blood cell analyzer 300 without burdening the operator.
According to this embodiment, the second cassette transport part 8 also has the function of transporting the cassettes 3 storing the stained slide glasses 10 to the port 9a of the keeping part 9 of the blood smear preparation apparatus 100, whereby the single second cassette transport part 8 can distribute the cassettes 3 storing the stained slide glasses 10 to the port 9a of the keeping part 9 and the inlet 300a of the automatic blood cell analyzer 300 when the blood smear preparation apparatus 100 prepares two types of specimens, i.e., those supplied to the automatic blood cell analyzer 300 and those kept in the keeping part 9.
According to this embodiment, the blood smear preparation apparatus 100, provided with the control part 110 controlling the second cassette transport 8 to transport the cassettes 3 storing the stained slide glasses 10 to the port 9a of the keeping part 9 or the inlet 300a of the automatic blood cell analyzer 300, can easily distribute the cassettes 3 storing the stained slide glasses 10 to the port 9a of the keeping part 9 and the inlet 300a of the automatic blood cell analyzer 300 respectively.
According to this embodiment, the keeping part 9 of the blood smear preparation apparatus 100 is provided with the feed part 9b moving the cassettes 3 transported to the port 9a of the keeping part 9 toward the keeping part 9 while the control part 110 controls the feed part 9b to move the cassettes 3 toward the keeping part 9 when the second cassette transport part 8 transports the stained slide glasses 10 to the port 9a of the keeping part 9, whereby the second transport part 8 can easily move the cassettes 3 storing the stained slide glasses 10 transported to the port 9a of the keeping part 9 toward the keeping part 9.
According to this embodiment, the second cassette transport part 8, provided with the moving member 81 coming into contact with the cassettes 3 for moving the same and the drive motor 86 driving the moving member 81, can easily transport the cassettes 3 to the inlet 300a of the automatic blood cell analyzer 300 with the moving member 81.
According to this embodiment, the moving member 81 of the second cassette transport part 8 is provided with the contact parts 81a and 81b coming into contact with the side face parts 3h and 3j of the cassettes 3 respectively so that the contact parts 81a and 81b of the moving member 81 can come into contact with the side face parts 3h and 3j of the cassettes 3 respectively, whereby the second cassette transport part 8 can stably transport the cassettes 3 to the inlet 300a of the automatic blood cell analyzer 300.
According to this embodiment, the second cassette transport part 8 is provided with the transport paths 8d and 8e arranged on the prescribed region in the blood smear preparation apparatus 100 and at the inlet 300a of the automatic blood cell analyzer 300 respectively to be capable of moving the cassettes 3 from the transport starting position 80 to the inlet 300a of the automatic blood cell analyzer 300 through the port 9a of the keeping part 9 of the blood smear preparation apparatus 100 along the transport paths 8d and 8e, whereby the second transport part 8 can easily transport the cassettes 3 to the port 9a of the keeping part 9 of the blood smear preparation apparatus 100 or the inlet 300a of the automatic blood cell analyzer 300.
According to this embodiment, the cassette detection part 8c, provided on the transport starting position 80 of the second cassette transport part 8 for detecting arrival of the cassettes 3 storing the stained slide glasses 10, can easily detect arrival of the cassettes 3 storing the stained slide glasses 10 on the transport starting position 80 of the second cassette transport part 8.
According to this embodiment, the sucking/dispensing mechanism part 1 has the function of dispensing the same blood (specimen) on two slide glasses 10 while regulating the volume of the dispensed blood to those corresponding to the automatically analyzed and visually observed specimens respectively, whereby the specimen preparation/analysis system can easily prepare the specimen analyzed in the automatic blood cell analyzer 300 and the visually recognized specimen from the same blood.
According to this embodiment, the blood smear preparation apparatus 100 is provided with the printing part 2g for printing the two-dimensional bar codes 10b storing the specimen information on the frosted parts 10a of the slide glasses 10 while the automatic blood cell analyzer 300 is provided with the bar code reading part 304 reading the two-dimensional bar codes 10b, whereby the contents of the specimen information printed on the frosted parts 10a of the slide glasses 10 can be increased through the two-dimensional bar codes 10b capable of storing larger quantities of information than one-dimensional bar codes. Also when the second cassette transport part 8 automatically supplies the cassettes 3 storing the stained slide glasses (specimens) 10 to the automatic blood cell analyzer 300, confusion between the specimens can be suppressed by confirming the specimen information through the bar code reading part 304 before the automatic blood cell analyzer 300 analyzes the specimens.
According to this embodiment, the two-dimensional bar code 10b storing the specimen information is printed on the frosted part 10a of each slide glass 10 so that the slide glass 10 can hold a large quantity of detailed specimen information due to the two-dimensional bar code 10b capable of storing a larger quantity of information than a one-dimensional bar code. Consequently, the operator can confirm a large quantity of detailed specimen information related to a prescribed slide glass (specimen) 10 by reading the two-dimensional bar code 10b printed on the prescribed slide glass 10 without inquiring the corresponding specimen information from the host computer 400. In this case, the text data (10c to 10e) are also printed on the frosted part 10a of the slide glass 10 as the specimen information in addition to the two-dimensional bar code 10b so that the size of the print area of the two-dimensional bar code 10b can be reduced through the large quantity of information storable in the two-dimensional bar code 10b, whereby the size of the print area of the text data (10c to 10e) can be increased. Thus, the slide glass 10 can hold a large quantity of text data (10c to 10e) as the specimen information. Therefore, when the two-dimensional bar code 10b printed on the prescribed slide glass 10 is hard to read, for example, the operator can confirm the large quantity of specimen information related to the prescribed slide glass (specimen) 10 through the visually recognizable text data (10c to 10e) without inquiring the specimen information of the corresponding slide glass 10 from the host computer 400.
According to this embodiment, the bar code print area F1 and the text print area F2 of the frosted part 10a printed with the two-dimensional bar code 10b and the text data (10c to 10e) respectively are arranged to be adjacent to each other along the shorter direction of the slide glass 10 so that the length of the specimen preparation area 10f along the longitudinal direction of the slide glass 10 can be increased as compared with a case of arranging the bar code print area F1 and the text print area F2 to be adjacent to each other along the longitudinal direction of the slide glass 10 having the frosted part 10a arranged on the region closer to one end of the slide glass 10 along the longitudinal direction thereof. Thus, the size of the specimen preparation area 10f of the slide glass 10 having the frosted part 10a arranged on the region closer to one end of the slide glass 10 along the longitudinal direction thereof is not reduced despite the bar code print area F1 and the text print area F2 arranged on the frosted part 10a. In this case, the two-dimensional bar code 10b is so formed in the square shape in plan view that the text print area F2 remains unchanged also when the direction of arrangement of the two-dimensional bar code 10b is changed.
According to this embodiment, the text data (10c to 10e), divided into the three rows of different types of data, i.e., the date 10c, the name 10d and the sample number 10c, are easier to read as compared with a case of wholly displaying the date 10c, the name 10d and the sample number 10c in one row. In this case, the three rows of text data (10c to 10e) are arranged to be adjacent to each other along the longitudinal direction of the slide glass 10 while the characters and numerals constituting the text data (10c to 10e) respectively are arranged along the shorter direction of the slide glass 10, whereby the text data (10c to 10e) are more easily readable.
According to this embodiment, the three rows of text data (10c to 10e) are so arranged that the lengths of the bar code print area F1 and the text print area F2 are equal to each other along the longitudinal direction of the slide glass 10, whereby the frosted part 10a of the slide glass 10 can be inhibited from wasting of a dead region provided with no specimen information.
According to this embodiment, the printable coating film 10g is formed on the region of the slide glass 10 corresponding to the frost part 10a while the two-dimensional bar code 10b and the three rows of text data (10c to 10e) are printed on the upper surface of the coating film 10g located on the frosted part 10a, whereby the frosted part 10a of the slide glass 10 can easily display the specimen information (the sample number, the date, the serial number and the name). In this case, the coating film 10g is formed to extend from the frosted part 10a along the longitudinal direction of the slide glass 10 for holding the specimen preparation area 10f, so that a plurality of slide glasses 10 superposed with each other can be inhibited from adhering to each other.
Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the spirit and scope of the present invention being limited only by the terms of the appended claims.

In the specimen preparation/analysis system according to the first modification of this embodiment, as hereinabove described, the blood smear preparation apparatus 500 is provided with the slide glass transport part 503 for transporting the stained slide glasses (specimens) unloaded from the cassettes to the inlet 600a of the automatic blood cell analyzer 600, whereby the slide glass transport part 503 can automatically supply the specimens (slide glasses) from the blood smear preparation apparatus 500 to the automatic blood cell analyzer 600. Thus, the specimen preparation/analysis system can supply the specimens (slide glasses) from the blood smear preparation apparatus 500 to the automatic blood cell analyzer 600 without burdening the operator.
In the specimen preparation/analysis system according to the first modification of this embodiment, the blood smear preparation apparatus 500 is provided with the slide glass unloading part 501 for unloading the stained slide glasses from the cassettes transported by the second cassette transport part 8 from the staining part 7, whereby the slide glass unloading part 501 can easily unload the stained slide glasses from the cassettes. Thus, the slide glass transport part 503 can easily transport the stained slide glasses unloaded from the cassettes to the inlet 600a of the automatic blood cell analyzer 600.
While the second cassette transport part transports the cassettes storing the stained slide glasses to the inlet of the automatic blood cell analyzer in the aforementioned embodiment, the present invention is not restricted to this but another unit may be provided for receiving the cassettes storing the stained slide glasses and supplying the same to the automatic blood cell analyzer so that the cassettes storing the stained slide glasses are transported to an inlet of this unit. In this case, the specimen preparation/analysis system including the blood smear preparation apparatus and the automatic blood cell analyzer preferably has a structure such as that of a second modification shown in FIG. 20.
More specifically, a specimen preparation/analysis system according to the second modification of the embodiment includes a cassette storage part 302 of an automatic blood cell analyzer 300 identical to that shown in FIG. 2 in a cassette supply unit 700 provided independently of the automatic blood cell analyzer 300, as shown in FIG. 20. The cassette storage part 302 of the cassette supply unit 700 is provided with a supply part 701 for supplying cassettes storing stained slide glasses to the automatic blood cell analyzer 300. The cassette storage part 302 of the cassette supply unit 700 stores the cassettes storing the stained slide glasses transported from the staining part 7 of the blood smear preparation apparatus 100 by the second cassette transport part 8 through the inlet 700a. The supply part 701 supplies the cassettes storing the stained slide glasses stored in the cassette storage part 302 of the cassette supply unit 700 to the automatic blood cell analyzer 300. The cassette supply unit 700 also includes a cassette keeping part 307. This cassette keeping unit 307 of the cassette supply unit 700 is provided for keeping the cassettes releasing the stained slide glasses after the slide glass unloading part 303 of the automatic blood cell analyzer 300 unloads the stained slide glasses from the cassettes. The remaining structure of the specimen preparation/analysis system according to the second modification of the embodiment is similar to that of the aforementioned embodiment.
As hereinabove described, the specimen preparation/analysis system according to the second modification of the embodiment, provided with the cassette supply unit 700 storing the cassettes storing the stained slide glasses and supplying the same to the automatic blood cell analyzer 300, can automatically supply the cassettes storing the stained slide glasses to the automatic blood cell analyzer 300 from the blood smear preparation apparatus 100 through the cassette supply unit 700. Thus, the specimen preparation/analysis system can automatically supply the cassettes storing the stained slide glasses to the automatic blood cell analyzer 300 from the blood smear preparation apparatus 100 without burdening the operator. Further, the specimen preparation/analysis system supplying the cassettes storing the stained slide glasses to the automatic blood cell analyzer 300 through the cassette supply unit 700 independent of the automatic blood cell analyzer 300 can easily solely operate the automatic blood cell analyzer 300 by removing the cassette supply unit 700.
While the printable coating film 10g is formed on the region of the slide glass 10 corresponding to the frosted part 10a and the two-dimensional bar code 10b as well as the three rows of text data (10c to 10e) are printed on the upper surface of this coating film 10g in the aforementioned embodiment, the present invention is not restricted to this but the slide glass 10 may alternatively be constituted similarly to a slide glass 10 according to a third modification of the embodiment shown in FIG. 21. More specifically, a label 11 printed with a two-dimensional bar code 10a and three rows of text data (a date 11b, a name 11c and a sample number 11d) may be attached to a region of the slide glass 10 corresponding to a frosted part 10a, as shown in FIG. 21.
While the coating film provided on the region of the slide glass corresponding to the frosted part is formed to extend from the frosted part along the longitudinal direction of the slide glass for holding the specimen preparation area in the aforementioned embodiment, the present invention is not restricted to this but another coating film of a material different from that of the coating film provided on the region corresponding to the frosted part may alternatively be formed to extend from the frosted part along the longitudinal direction of the slide glass for holding the specimen preparation area.
While the two-dimensional bar code stores the specimen information such as the sample number, the date, the serial number and the name in the aforementioned embodiment, the present invention is not restricted to this but the two-dimensional bar code may alternatively store information selected from results of analysis measured in a blood analyzer and results of WBC (white blood cell), RBC (red blood cell), HGB (hemoglobin concentration), HCT (hematocrit), MCV (mean cell volume), MCH (mean cell hemoglobin), MCHC (mean cell hemoglobin concentration), PLT (number of platelets) and five types of white blood cells (neutrophil, eosinophil, basophil, monocyte and lymphocyte) as specimen information. According to the aforementioned embodiment, the two-dimensional bar code so stores the specimen information that the slide glass can hold a large quantity of information such as the aforementioned results of analysis. If the slide glass holds the aforementioned results of analysis, the operator can recognize the results of analysis made on a prescribed specimen prepared on a corresponding slide glass in addition to the specimen information such as the sample number by reading the two-dimensional bar code when reanalyzing the specimen after temporarily keeping the slide glass. Thus, the operator may not inquire the aforementioned results of analysis etc. from the host computer when reanalyzing the specimen prepared on the temporarily kept slide glass.
While the text data displayed on the frosted part of the slide glass are constituted of numerals and/or alphabetic characters in the aforementioned embodiment, the present invention is not restricted to this but the text data may alternatively be constituted of Chinese, hiragana and/or katakana characters in place of the numerals and/or alphabetic characters.
