Mills / Sega Slots - Why no coin return/reject button ?

[coppinpr]

My view is that its not that they trusted the quality of their machines but perhaps the reverse,ill bet everyone here has had a machine at some time where the coin reject button has become faulty and either rejects all coins or you have to keep pushing the button to get it to decide if its good or bad ,I think they decided it was more trouble than it was worth.

If the Shefras escalator is fitted, the coin rejection takes place as the handle is pulled. Either the handle unlocks and operates the reels or the handle locks up and you hear the clatter of an unwanted coin dropping into the winnings tray.

Having just reread the waffle I wrote so confidently seven and a bit years ago the only excuse I can offer for my approach to the question in hand is that I have no memory at all of this thread.

Rethinking it through and putting myself in the shoes of a large manufacturer attempting to feed a worldwide market and keeping prices down. I guess I would choose to manufacture slots, slides and escalators that would accept the majority of popular coins available in the countries I was trading in. We all know those particular parts tend to be slightly oversize and that many different coin blanks from various countries are interchangeable.
Therefore keeping to the cheaper is better theme I'd probably rely on the coin slot to measure the thickness and maximum diameter, and the open sided chute to reject any below minimum diameter. I'd also depend on the coin detector pin to ignore washers. So why would I need more?

I can only imagine I'd start to consider reject mechanisms if the machine was going to earn its living in a club or casino where the playing stakes would be impressively high. In which case I'd probably be designing more impressive looking machines including the new fangled elektrikery.

Perhaps in 2022 I'll read this again and wonder what the hell this idiot is talking about now!
