## Abstract

An examination apparatus includes a measurement line that performs a measurement process while transporting a cartridge for measurement along a transport passage for measurement, a pre-treatment line that performs a pre-treatment while transporting a cartridge for pre-treatment along a transport passage for pre-treatment, and a specimen transfer mechanism that transfers a pre-treated specimen in which a pre-treatment is completed from the cartridge for pre-treatment in the pre-treatment line to the cartridge for measurement in the measurement line, and the transport passage for pre-treatment and the transport passage for measurement are arranged such that a pre-treatment end position in the transport passage for pre-treatment, at which the pre-treatment is completed, is closer to an upstream side in a transport direction of the transport passage for measurement than a downstream side in the transport direction.

## Claims

### Claim 1

An examination apparatus for performing a measurement process using a cartridge for measurement, which has a reaction cell in which a specimen is dispensed and mixed with a reagent, the examination apparatus comprising:
a measurement line that has a transport passage for measurement, which linearly transports the cartridge for measurement in one direction from an upstream side to a downstream side, and that performs the measurement process while transporting the cartridge for measurement along the transport passage for measurement;
a pre-treatment line that performs a pre-treatment in which, before performing the measurement process, the specimen is heated in a state in which the specimen is mixed with a pre-treatment liquid, the pre-treatment line having a transport passage for pre-treatment, which transports a cartridge for pre-treatment used in the pre-treatment, the cartridge for pre-treatment being different from the cartridge for measurement, and the pre-treatment line performing the pre-treatment while transporting the cartridge for pre-treatment along the transport passage for pre-treatment; and
a specimen transfer mechanism that transfers a pre-treated specimen in which the pre-treatment is completed, from the cartridge for pre-treatment in the pre-treatment line to the cartridge for measurement in the measurement line,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged such that a pre-treatment end position in the transport passage for pre-treatment, at which the pre-treatment is completed, is closer to the upstream side in a transport direction of the transport passage for measurement than the downstream side in the transport direction.

### Claim 2 (depends on 1)

The examination apparatus according to claim 1,
wherein the transport passage for pre-treatment is a transport passage that linearly transports the cartridge for pre-treatment in one direction from an upstream side to a downstream side, similarly to the transport passage for measurement.

### Claim 3 (depends on 2)

The examination apparatus according to claim 2,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged such that the downstream side in the transport direction of the transport passage for pre-treatment is closest to the upstream side in the transport direction of the transport passage for measurement.

### Claim 4 (depends on 2)

The examination apparatus according to claim 2,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged in series so as to be connected in a straight line.

### Claim 5 (depends on 2)

The examination apparatus according to claim 2,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged such that the transport directions are parallel to each other and the downstream side of the transport passage for pre-treatment and the upstream side of the transport passage for measurement partially overlap each other.

### Claim 6 (depends on 2)

The examination apparatus according to claim 2,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged such that the transport directions are parallel to each other and the upstream side and the downstream side of each transport direction are opposite to each other.

### Claim 7 (depends on 2)

The examination apparatus according to claim 2,
wherein the transport passage for pre-treatment and the transport passage for measurement are arranged such that the transport directions are orthogonal to each other.

### Claim 8 (depends on 2)

The examination apparatus according to claim 2,
wherein at least one of the transport passage for pre-treatment or the transport passage for measurement is provided in plurality.

### Claim 9 (depends on 1)

The examination apparatus according to claim 1,
wherein the transport passage for pre-treatment has an annular shape.

### Claim 10 (depends on 1)

The examination apparatus according to claim 1,
wherein, in the transport passage for pre-treatment, at least one of a pre-treatment start position at which the pre-treatment is started or the pre-treatment end position is variable.

### Claim 11 (depends on 1)

The examination apparatus according to claim 1,
wherein the specimen transfer mechanism is a dispensing mechanism that suctions the pre-treated specimen from the cartridge for pre-treatment and discharges the pre-treated specimen to the cartridge for measurement.

### Claim 12 (depends on 11)

The examination apparatus according to claim 11,
wherein the dispensing mechanism is capable of suctioning the pre-treated specimen from the cartridge for pre-treatment at any position on the transport passage for pre-treatment.

### Claim 13 (depends on 1)

The examination apparatus according to claim 1,
wherein the measurement line and the pre-treatment line each have a heating unit which heats the specimen, and
each heating unit is controllable to a different temperature.
