In my childhood, such devices were installed in buses. On the right side, a ticket would twist out of the blue gadget, and a coin could be thrown into the top slot (or not – it depended on your conscience; tickets could be twisted out without a nickel). Alternatively, there was an open window at the driver’s where you could toss a nickel after your ride. There were no conductors at all. Back then, it was believed that the Soviet person had reached a sufficient level of consciousness, and his conscience could be the best controller. In the second photo – a puncher for ticket validation. It appeared later. Here, a ticket purchased with the help of a live seller was punched, the conscience-driven system was somewhat softer, but theoretically, the same ticket could be used ten times (though holes were punched differently, who really looked at that?)
