## Abstract

A board conveyance device and conveyance belt inspection method that enable easy detection of a problem with conveyance belts. The board conveyance device includes: endless conveyance belts on which is set a conveyance path for conveying a board; a board sensor configured to detect the presence of the board at a specified detection position on the conveyance path; and a control section configured to, in a case in which the board is not being conveyed on the conveyance path, move the conveyance belts and determine a problem with the conveyance belts based on a detection result of the board sensor.

## Claims

### Claim 1

A board conveyance device comprising:
an endless conveyance belt on which is set a conveyance path for conveying a board;
a board sensor configured to detect the presence of the board at a specified detection position on the conveyance path; and
a control section configured to, in a case in which the board is not being conveyed on the conveyance path, move the conveyance belt and determine a problem with the conveyance belt based on a detection result of the board sensor.

### Claim 2 (depends on 1)

The board conveyance device according to claim 1, further provided with a display device configured to display the determination result of the control device.

### Claim 3

A conveyance belt inspection method comprising:
a detecting step for detecting the presence of a passing object at a specified detection position of a conveyance path by moving an endless conveyance belt in a case in which a board is not being conveyed at the conveyance path set by the endless conveyor belt; and
a determining step for determining a problem with the conveyance belt based on the detection result from the detecting step.
