Sensor at the insert slot detects the cassette.
It is determined if it is a cassette or not by the status of
the following sensors at the insertion slot when the
cassette is inserted.
•
Insert slot detection sensor 1
•
Insert slot detection sensor 2
•
Back plate drop detection sensor
When the cassette is inserted correctly, insert slot
detection sensor 1 and back plate drop detection
sensor will both go ON. In all other cases, it will
generate an error as foreign object insertion or
cassette insertion position error.
51
Barcode reader reads the barcode.
Following check will be performed by barcode reader
reading the barcode.
•
If the barcode is correctly read
•
If the plate size is smaller than calibration size
•
If there is no discrepancy between the inserted
cassette (status of the insert slot detection
sensor 1 and insert slot detection sensor 2) and
the cassette size from the barcode.
52
Shutter will open and cassette will rest on the
receiver.
Shutter will open by rotating the ShutterMotor.
Cassette will fall onto the receiver, and receiver sensor
will detect the cassette.
53
Receiver will lower to the first falling position.
Receiver motor will rotate, according to the cassette
size from the barcode, and receiver will lower to the
first falling position.
First falling position: The lowest position that the
