Daiichi machine

[Drunkenclam]

Daiichi OL倶楽部 or OL Club (OL abbrev for Office Lady)

I think from 1996


No ball dump for those stuck balls. In the old days. The machine would hold balls internally because it hadn't paid out. Each on of those balls is a winning ball. But couldn't payout due to either error or empty rear tank. So they build up inside and get stuck. there is normally a switch and solenoid at the exit point that releases each ball after a pay out. My old Monaco had a manual release by movign the solenoid. but it only did one ball at a time. Not sure about Daiichi, But sounds like you found something similar.
