reasons: (1) Satoh describes a torsion spring, while claim 4
recites a coil spring for biasing the slider lock portion in a
downward direction; (2) the spring in Satoh biases the slider
towards a closed position and does not bias the slider lock
member in a downward position, as claimed; (3) the bent-in
portion of the torsion spring in Satoh engages a groove 112
formed in the boss 108 and is not wound around the pin as
claimed.
We disagree with the Examiner's reasons. The torsion
spring in Satoh biases the slider and is not "interposed
between the slider lock portion and said upper cassette part,

proposed modification were made, the combination does not
provide the claimed structure or function. In addition, the
bent-in portion of the spring 106 in Satoh is inserted into
