  • Ticket dispenser retrofit
    Patent number: 5386934

A smooth top surface adjacent the guide rail accommodates the narrower tickets. The feed slide has a first opening for accommodating the sensing device of the ticket dispenser and a second opening for accommodating a drive roller and guide roller of the ticket dispenser retrofit.
