Assembly and Operating Manual
IX. TICKET
DISPENSER
A. Basic operation of ticket dispenser model DL1275H
When the control unit calls for a ticket to be issued, the motor in the dispenser is turned on. When a
ticket is dispensed, the opto beam breaker senses a notch in the ticket and sends back a signal to the
control unit. At this time the ticket counter is incremented. If no ore tickets are called for the motor is
turned off.
Tickets are moved through the ticket chute by means of a power driven roller which is spring loaded
against an idler roller. The power driven roller has two Neoprene O Rings installed, and under normal
operating conditions are the only contact with the tickets. The power driven roller is mounted on the
output shaft of the motor gear train assembly. The motor assembly is mounted to the pivot bracket
assembly in the two Oilite Bearings. The motor assembly has a limited free swing, limited by a single
pin engaged in the brake sprag. The brake sprag engages the roller as an anti theft device. With the free
swing of the motor assembly, the direction of torque, when the electric power is applied, is in a direction
so as to release the brake sprag. When an attempt is made to pull tickets from the machine with the
power off, the torque is reversed and the brake sprag is engaged. Also, the pulling of tickets will cause
the pivot bracket assembly to apply a pressure to the power driven roller against the ticket and idler roller
greater than the pre-set spring load. This will cause the O Rings to depress and the course knurled
surface of the roller will then grip the tickets. One ounce of pull will apply 20 lbs. of pressure on the
rollers.
B. Ticket Dispenser Components
1. Controller
Board
Attached to the ticket machine is a transistor motor controller which provides dynamic braking to
ensure accurate and repeatable ticket stopping after issuing any number of tickets. Included as part
of the controller is ticket sensing by means of an Opto Beam Breaking Sensor. Also included in the
signal conditioning which provides high electrical noise immunity. The output of the ticket sensing
circuitry is the equivalent to a single pole double throw switch.
2. Roller Tension Spring
The roller tension spring keeps constant tension on the tickets, which insures proper delivery and
prevents tickets from being pulled through when the dispenser is idle. To increase tension, loosen
screw and move spring forward. Tension is adjusted correctly when the tickets cannot be pulled
from the dispenser.
3. Ticket Guide Spring
The ticket guide spring insures that the notches in the tickets pass through the Opto Beam Breaker
Sensor. To increase tension, loosen screw and move other spring up. This changes the tension of the
inner spring. Tickets should be snug between spring and side plate but not deformed by excess
tension. This spring is adjusted at the factory for 1-3/16” wide tickets.
