Automatic analyzer

1. An automatic analyzer comprising:

an analysis module including a sample dispensing mechanism that aspirates a sample from a sample container and discharges the aspirated sample into a reaction container, a reagent dispensing mechanism that aspirates a reagent from a reagent container and discharges the aspirated reagent into the reaction container, and a photometer that measures the sample in the reaction container;

first and second physical position adjustment switches and a physical operation switching switch that are disposed on a housing of the analysis module and are operated by an operator to adjust an operation position of either the sample dispensing mechanism or the reagent dispensing mechanism; and

a controller configured to:

drive the sample dispensing mechanism or the reagent dispensing mechanism according to a first position adjustment instruction from the first position adjustment switch and a second position adjustment instruction from the second position adjustment switch, and

receive a selection of selecting either the sample dispensing mechanism or the reagent dispensing mechanism to be adjusted by the first position adjustment switch,

wherein the first position adjustment switch and the second position adjustment switch are disposed to be separated from each other by a distance at which the first position adjustment switch and the second position adjustment switch are not operable by a single hand of the operator at the same time,

wherein the first position adjustment switch is disposed on one end side of an upper surface of the housing,

wherein the second position adjustment switch is disposed on the other end side of the upper surface of the housing, and

wherein the controller is further configured to:

determine whether the first position adjustment switch is pressed based on the first position adjustment instruction signal input from the first position adjustment switch,

determine whether the second position adjustment switch is pressed based on the second position adjustment instruction signal input from the second position adjustment switch, and

determine whether the first position adjustment switch adjusts the operation position of the sample dispensing mechanism or the reagent dispensing mechanism or the first position adjustment switch selects a position adjustment point based on an input signal from the operation switching switch,

upon determining the first position adjustment switch adjusts the operation position of the sample dispensing mechanism or the reagent dispensing mechanism, as selected, adjust an operation position of either the sample dispensing mechanism or the reagent dispensing mechanism, as selected, according to the input first position adjustment instruction from the first position adjustment switch only upon determining the second position adjustment switch is simultaneously pressed based on the input second position adjustment instruction, and

upon determining the first position adjustment switch selects a position adjustment point based on an input signal from the operation switching switch, drive the sample dispensing mechanism or the reagent dispensing mechanism toward a selected position adjustment point based on the input first position adjustment instruction switch only upon determining the second position adjustment switch is simultaneously pressed based on the input second position adjustment instruction,

wherein the position adjustment point indicates a position of one of an aspiration position, a discharge position, and a cleaning position of the sample dispensing mechanism or the reagent dispensing mechanism, as selected.

2. The automatic analyzer according to claim 1 , wherein

the first position adjustment switch and the second position adjustment switch are disposed separated from each other by 30 cm or more.

3. The automatic analyzer according to claim 2 , further comprising:

an interlocking cover that covers the analysis module,

wherein the controller is configured to:

stop the sample dispensing mechanism and the reagent dispensing mechanism upon determining the interlocking cover is open, and upon determining the interlocking cover is open while the second position adjustment switch is simultaneously pressed, operate the sample dispensing mechanism and the reagent dispensing mechanism from the stopped state.

4. The automatic analyzer according to claim 1 , further comprising:

an interlocking cover that covers the analysis module,

wherein the controller is configured to:

stop the sample dispensing mechanism and the reagent dispensing mechanism upon determining the interlocking cover is open, and upon determining the interlocking cover is open while the second position adjustment switch is simultaneously pressed, operate the sample dispensing mechanism and the reagent dispensing mechanism from the stopped state.

5. The automatic analyzer according to claim 4 , further comprising:

an operation switching switch,

wherein the controller is configured to:

upon determining the interlocking cover is open and the first position adjustment switch selects a position adjustment point based on an input signal from the operation switching switch, drive the sample dispensing mechanism or the reagent dispensing mechanism toward a selected position adjustment point based on the input first position adjustment instruction switch only upon determining the second position adjustment switch is simultaneously pressed based on the input second position adjustment instruction.

6. The automatic analyzer according to claim 5 , further comprising:

wherein the operation switching switch is disposed at a distance of less than 15 cm from the first position adjustment switch or the second position adjustment switch.

7. The automatic analyzer according to claim 6 ,

further comprising: third and fourth position adjustment switches, a second operation switching switch, and a second interlocking cover are disposed on a back surface of the housing, and

wherein the first and second position adjustment switches, the operation switching switch as a first operation switch, and the interlocking cover as a first interlocking cover are disposed on a front surface of the housing, and

wherein the controller is configured to:

upon determining the second position adjustment switch disposed on the front surface of the housing is pressed ignore instructions based on input signals from the third position adjustment switch and the second operation switching switch, and

upon determining the fourth position adjustment switch is pressed ignore instructions based on input signals from the first position adjustment switch and the first operation switching switch.

8. The automatic analyzer according to claim 4 , wherein

the first position adjustment switch and the second position adjustment switch are disposed with the interlocking cover interposed therebetween.

9. The automatic analyzer according to claim 1 ,

further comprising: third and fourth position adjustment switches, and a second interlocking cover are disposed on a back surface of the housing, and

wherein the first and second position adjustment switches and the interlocking cover, as a first interlocking cover, are disposed on a front surface of the housing, and

wherein the controller is configured to:

upon determining the second position adjustment switch is pressed ignore instructions based on input signals from the third position adjustment switch, and

upon determining the fourth position adjustment switch is pressed ignore instructions based on input signals from the first position adjustment switch.

10. The automatic analyzer according to claim 1 , wherein the controller is configured to generate an alarm upon determining an interlocking cover is open, and

upon determining the interlocking cover is open and upon determining the second position adjustment switch is simultaneously pressed based on the input second position adjustment instruction, do not generate the alarm.
