Printer module paper feed-out procedure

Abstract

A printer module paper feed-out procedure in which a sheet-transfer roller set transfers the paper sheet forwards during printing, and paper feed-out rollers are rotated forwards for a predetermined time period and then stopped so that the paper feed-out rollers hold down the lead end of the paper sheet when the printing action of the printing head and the paper sheet transferring action of the sheet-transfer roller set are being continued, and then a paper cutting unit is operated to cut off the printed front part of the paper sheet when the printing action is finished, and then the paper feed-out rollers are rotated to transfer the cutoff piece of paper out of a paper outlet of a face panel of the printer module and then he paper feed-out rollers are stopped to hold down the rear end of the cutoff piece of paper, avoiding falling of the cutoff piece of paper away from the paper outlet of the face panel.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a printer module for using in a game machine, lottery machine, ticket issuing machine or any of a variety of automatic vending machines for issuing a receipt, evidence of payment, certificate or the like, and more particularly, to a printer module paper feed-out procedure for printer module, which uses paper feed-out rollers to hold down the lead end of the paper sheet for enabling the printed part of the paper sheet to be detained in a spare space inside the printing module, and then to transfer the cutoff piece of paper to the out side of the paper outlet on the face panel of the printer module and to hold down the rear end of the cutoff piece of paper after the cutoff piece of paper has been transferred to the outside of the paper outlet, so that when a person takes the printed cutoff piece of paper, the paper sheet of the paper roll will not be stretched, and the printing on the prin...

AI Technical Summary

Benefits of technology

[0009]The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a printer module paper feed-out procedure for printer module, which avoids waste of paper, keeps the printing clear, and prevents damage to the internal parts of the printer module when the user takes away the printed cutoff piece of paper.

[0010]To achieve this and other objects of the present invention, the printer module paper feed-out procedure, which enables paper feed-out rollers to be rotated for a predetermined time period to catch the lead end of the paper sheet and then stopped when the paper sheet is being transferred forwards by a sheet-transfer roller set, so that the printed part of the paper sheet is detained in a spare space between the paper cutting unit and the paper feed-out unit of the printer module. When the printing action is finished, the printer module paper feed-out procedure stops the sheet-transfer roller set and drives the paper cutting unit to cut off the paper sheet, and then enables the paper feed-out rollers to transfer the cutoff piece of paper out of the paper outlet of the face panel of the printer module. Because the paper sheet is kept inside the printer module during the printing action of the printing unit, the invention avoids stretching of the paper sheet by a person during printing. Therefore, no any extra part of the paper sheet will be wasted, and the printing of the cutoff piece of paper is kept clear.

[0011]Further, because the cutoff piece of paper has been separated from the paper sheet of the paper roll, any person taking the cutoff piece of paper does not stretch the paper sheet to damage the sheet-transfer roller set or the paper feed-out rollers.

Problems solved by technology

The application of these advanced machines saves much labor, and enables the business to run 24 hours a day.

When the paper sheet is stretched before the end of the printing action, the printing will rubbed against the internal parts of the machine, and the paper sheet may be torn, resulting in a paper waste or printing vague problem and lowering the consumer's will to use the machine again.
