Ticket Printer with Manual and Automatic Ticket Feed

The drawing shows a schematic of a printer which can be used to print tickets (or other documents), which are fed into the printer either manually or automatically.

Printer 1 includes a bank of continuously rotating print wheels 2 arranged side-by-side across the width of a ticket. The number of wheels 2 will depend on the number of print positions desired across the ticket. Associated with each print wheel 2 is a print hammer 3, which is caused to impact the back of the ticket when a desired character is opposite hammer 3. Light detectors 4 and 5 are used to detect the presence of a ticket within feed path 6: their operation is described in detail below.

A pair of reversible feed rollers 7 allows tickets 8 in the form of continuous stationery to be fed from cartridge 9. As an alternative to cartridge 9 with its continuous form, a roll feed may be used. Cutter 10 operable against anvil 11 is used to separate individual tickets from the continuous form.

To load printer 1 with blank tickets, the operator feeds continuous form ticket 8 between feed rollers 7 after activating a feed or print button. Continuous form 8 will be advanced along feed path 6 until its leading edge is at detector 4. The printer is now ready for use.

Assume that after a printing cycle, form 8 has been advanced by printer rollers 13 until the trailing edge of the ticket being printed is detected by detector
5. Cutter 10 is automatically operated allowing...
