## Abstract

Provided is an automatic analyzer in which user work is in conjunction with apparatus driving and operation of a user even in complicated maintenance work is simplified. The automatic analyzer includes a measurement device 2 and a control device 3. The control device controls the measurement device. The control device includes an input unit 32 that receives a start instruction of maintenance work by a user, a control unit 31 that controls an apparatus to perform a predetermined first processing in accordance with input, a driving unit that performs driving in accordance with processing of the control unit, a display unit 33 that displays a second processing to be performed by the user in conjunction with the first processing after the first processing is terminated by the driving unit. The control device sequentially guides maintenance work of the user by performing the first processing or the second processing after the displayed second processing is executed by the user.

## Claims

### Claim 1

An automatic analyzer comprising:
an input unit that receives a start instruction of maintenance work by a user;
a control unit that performs control of a predetermined first processing in accordance with input from the input unit;
a measurement device that includes a driving unit that performs driving in accordance with control of the control unit; and
a display unit that displays a second processing to be performed by the user in conjunction with the first processing after the first processing by the driving unit is terminated, wherein
the first processing is a processing of moving a rod-shaped member in a horizontal direction to a retraction position.

### Claim 2 (depends on 1)

The automatic analyzer according to claim 1, wherein
the control unit further performs control of the first processing after the second processing is executed.

### Claim 3 (depends on 1)

The automatic analyzer according to claim 1, wherein
the control unit locks a locking mechanism of the measurement device so that the user does not access the measurement device during the first processing, and releases the locking mechanism so that the user accesses the measurement device at time of transition to the second processing.

### Claim 4 (depends on 1)

The automatic analyzer according to claim 1, further comprising:
a monitoring unit that monitors whether a sample is being measured by the measurement device, wherein
when the monitoring unit determines that a sample is being measured, the control unit performs control so that the measurement device does not perform the first processing even if the start instruction is given.

### Claim 5 (depends on 1)

The automatic analyzer according to claim 1, wherein
the second processing includes a plurality of steps, and
the display unit displays the plurality of steps in a predetermined order.

### Claim 6 (depends on 1)

The automatic analyzer according to claim 1, wherein
the control unit stores maintenance work completion date and time in a memory unit after the maintenance work is completed.

### Claim 7 (depends on 1)

The automatic analyzer according to claim 1 comprising:
a position sensor that detects a position of the driving unit, wherein
when output of the position sensor is not in a predetermined state after the first processing or the second processing is executed, the control unit performs control not to shift to a next step.

### Claim 8 (depends on 1)

The automatic analyzer according to claim 1, wherein
the measurement device includes an analysis unit and a camera that images inside of the measurement device, and
the control unit performs control not to shift to a next step when it is determined that a maintenance target unit is not in a predetermined state as a result of determining an image obtained by imaging the maintenance target unit inside the analysis unit with the camera after the first processing or the second processing is executed.

### Claim 9 (depends on 1)

The automatic analyzer according to claim 1 comprising:
a transmission unit that transmits information related to the automatic analyzer to outside, wherein
the transmission unit transmits such information, to an electronic terminal capable of receiving the information, that the first processing is completed at time of completion of the first processing.

### Claim 10 (depends on 1)

The automatic analyzer according to claim 1 comprising:
a reception unit that receives information related to the automatic analyzer from outside, wherein
the user transmits the start instruction by using an electronic terminal capable of transmitting the information, thereby executing the first processing.

### Claim 11

A maintenance support method for an automatic analyzer which includes a control unit, a driving unit, and a display unit, the maintenance support method comprising:
controlling the driving unit, by the control unit, to perform a predetermined first processing in accordance with input of a start instruction of maintenance work by a user, and
causing the display unit to display, by the control unit, a second processing to be performed by the user in conjunction with the first processing after the first processing by the driving unit is terminated, wherein
the first processing is a processing of moving a rod-shaped member in a horizontal direction to a retraction position.

### Claim 12 (depends on 1)

The automatic analyzer according to claim 1, wherein
the rod-shaped member is a stirring rod, and
the second processing is cleaning of a dispensing probe.

### Claim 13 (depends on 1)

The automatic analyzer according to claim 1, wherein
the rod-shaped member is a dispensing probe, and
the second processing is cleaning of a cooling box.

### Claim 14 (depends on 11)

The maintenance support method according to claim 11, wherein
the rod-shaped member is a stirring rod, and
the second processing is cleaning of a dispensing probe.

### Claim 15 (depends on 11)

The maintenance support method according to claim 11, wherein
the rod-shaped member is a dispensing probe, and
the second processing is cleaning of a cooling box.
