a washing port for washing the reagent dispensing probes; and
a controller configured to control each of the reagent dispensing probes, wherein when the second arm of the one reagent dispensing probe of said pair is to be moved to the washing port and interferes with the other reagent dispensing probe of said pair by obstructing the working path, the controller moves the first arm of the one reagent dispensing probe of said pair to a position where the second arm of the one reagent dispensing probe of said pair does not interfere with the other reagent dispensing probe of said pair, and thereafter, the controller moves the second arm of the one reagent dispensing probe of said pair to the washing port without interfering with the other reagent dispensing probe of said pair.
2. The automatic analyzer according to claim 1, wherein the controller is further configured to control each of the reagent dispensing probes arranged on each of said reagent disks so that only one of said reagent dispensing probes arranged on each of said reagent disks sucks the reagent during one cycle of a rotation of said reaction disk.
3. The automatic analyzer according to claim 1, wherein a sample and a plurality of said reagents are reacted in a reaction process in one reaction cuvette, a plurality of said reagents used for reaction in one reaction cuvette being arranged on a same reagent disk.
4. The automatic analyzer according to claim 1, further comprising a sample probe for dispensing a sample into said reaction cuvette,
wherein said automatic analyzer comprises a plurality of sets, each of which includes one set of said sample dispensing probe, a plurality of said reagent dispensing probes, and one of said reagent disks, and said automatic analyzer controls only any one set of said plurality of sets to be used for one analysis item.
5. The automatic analyzer according to claim 1, wherein at least one of said plurality of said reagent disks are arranged on an inner side of said reaction disk and a rotation axis of said at least one of said plurality of said reagent disks is a same axis of said reaction disk.
6. The automatic analyzer according to claim 1, wherein each of said reagent containers is one reagent container package containing a first reagent and a second reagent, both of which are used for analyzing a same analysis item, and each said reagent container package is exchangeable.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An image processing apparatus capable of reading an image recorded on a first surface and a second surface of a sheet, the image processing apparatus comprising:
a conveying path comprising:
a first conveying path formed in a substantially plate shape;
a second conveying path disposed below the first conveying path; and
a curved conveying path disposed between the first conveying path and the second conveying path,
a conveying mechanism configured to convey the sheet along a conveying direction from the first conveying path to the second conveying path through the curved conveying path;
a first image reading section disposed below the first conveying path and comprising a first image sensor which reads the image recorded on the first surface of the sheet conveyed along the first conveying path at a first image reading position;
a second image reading section comprising a second image sensor which reads, from below the second conveying path at a second image reading position, the image recorded on the second surface of the sheet conveyed along the second conveying path; and
an upper cover configured to rotate between a closed position where the first conveying path is partly covered and an open position where the first conveying path is exposed, wherein the first conveying path and the first image sensor are exposed when the upper cover is in the open position,
wherein the first image reading section further comprises:
a first platen formed in a plate shape, which is transparent and configures a part of the first conveying path;
a first pressing member configured to press the sheet at the first image reading position on the first platen toward the first image sensor; and
a first urging member configured to urge the first pressing member toward the first platen, and
wherein the first pressing member is supported by the upper cover via the first urging member, and the first pressing member separates from the first platen when the upper cover is in the open position.
2. The image processing apparatus according to claim 1,
wherein the conveying mechanism comprises:
a driving roller comprising only one drive shaft in the curved conveying path; and
at least two pinch rollers urged by the driving roller,
wherein one pinch roller of the at least two pinch rollers which is positioned upstream in the conveying direction is supported by the upper cover, and the curved conveying path is also partly exposed by separating the one pinch roller from the driving roller when the upper cover is in the open position.
3. The image processing apparatus according to claim 1,
wherein the conveying mechanism comprises a pair of conveying rollers disposed upstream of the first conveying path in the conveying direction,
