Loose bits in Pioneer DVR105

Here’s the deal:
After watching a dvd in my pioneer DVR105 one night,
I found the next morn the drive wouldn’t function.
After removing the drive, I noticed a rattling sound.
Upon opening the drive I discovered 2 small springs &
a white plastic button/plunger thats clearly broken
on one side of it’s needle like “eye” [see attached photo]

It seems the only place would be near the lens assembly,
but I am unsure about BOTH springs…
