Optical disc device and lens cleaner

An optical disc device, comprising:

• a spindle motor that rotates a turntable to which an optical disc is attached;
• an optical head which emits light from an objective lens to the optical disc to perform recording or reproduction of information;
• an insertion detection optical sensor which detects that the optical disc is inserted into a disc insert slit based on light emitted from a first light emitting element to a first light receiving element being blocked;
• and
• an ejection detection optical sensor provided on a downstream side in a disc carry-in direction to the insertion detection optical sensor, the ejection detection optical sensor detecting that the optical disc is ejected to the disc insert slit based on light emitted from a second light emitting element to a second light receiving element being blocked, wherein
• in a state that the optical disc is attached onto the turntable, when the light emitted from the first light emitting element to the first light receiving element is blocked and the light emitted from the second light emitting element to the second light receiving element is not blocked, the optical disc device recognizes that a lens cleaner is attached onto the turntable as the optical disc, and the optical disc device performs a cleaning operation.
