## Abstract

A mounting device is provided with a first raising and lowering drive section configured to raise and lower an entire syringe member to which a suction nozzle that picks up a component is attached, and a second raising and lowering drive section 34 that raises and lowers the suction nozzle only of the syringe member to which the suction nozzle is attached. The mounting device controls a raising and lowering operation of the first raising and lowering drive section based on height information that includes at least one of information of the thickness of the component and information of the height of a board. With the mounting device, it is possible to move the entire syringe member to which the suction nozzle 28 is attached to a position closer to the board in accordance with the height of the board and the thickness of the component.

## Claims

### Claim 1

A mounting processing unit for arranging components on a board, the mounting processing unit comprising:
a first raising and lowering drive section configured to raise and lower an entire raising and lowering member to which a pickup member configured to pick up a component is attached;
a second raising and lowering drive section configured to raise and lower the pickup member of the raising and lowering member; and
a control section configured to control at least raising and lowering operation of the first raising and lowering drive section based on height information that includes at least one of component thickness information or information of board height measured by a measuring section.

### Claim 2 (depends on 1)

The mounting processing unit according to claim 1, wherein
the control section, using the information of the board height or the component thickness, or both the board height and the component thickness, included in the height information, controls raising and lowering operation of the first raising and lowering drive section such that the raising and lowering member is positioned at a stopping position of the raising and lowering member which is such that a distance between the board and the raising and lowering member is a distance corresponding to a raising and lowering stroke of the pickup member.

### Claim 3 (depends on 1)

The mounting processing unit according to claim 1, wherein
the control section sets a tip correction value used for raising and lowering control of the pickup member by the second raising and lowering drive section based on the height information, sets a raising and lowering correction value larger than the tip correction value and to be used for raising and lowering control of the raising and lowering member by the first raising and lowering section, controls raising and lowering operation of the first raising and lowering drive section using the raising and lowering correction value, and controls operation of the second raising and lowering drive section using the tip correction value.

### Claim 4 (depends on 1)

The mounting processing unit according to claim 1, wherein
the control section sets a raising and lowering correction value that corrects the stopping position on the board of the raising and lowering member based on the height information, controls raising and lowering operation of the first raising and lowering drive section by correcting a base value using the raising and lowering correction value, and controls raising and lowering operation of the second raising and lowering section using a base value.

### Claim 5 (depends on 1)

The mounting processing unit according to claim 1, further comprising:
a detecting section configured to detect a load applied to the pickup section, and wherein
the control section, in raising and lowering control of the raising and lowering member or the pickup member or both, measures at least one of the board height or the component thickness by detecting contact with a member to which the raising and lowering member is attached using the detecting section.

### Claim 6 (depends on 1)

A mounting device comprising the mounting processing unit according to claim 1.

### Claim 7

A control method for a processing mounting unit for arranging components on a board, provided with a first raising and lowering drive section configured to raise and lower an entire raising and lowering member to which a pickup member configured to pick up a component is attached, and a second raising and lowering drive section configured to raise and lower the pickup member of the raising and lowering member, the control method comprising:
a control step of controlling at least raising and lowering operation of the first raising and lowering drive section based on height information that includes at least one of information of component thickness or information of board height measured by a measuring section.
