Example Embodiment

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.

[0032] figure 1 It is a longitudinal sectional view of the first embodiment of the paper deviation correction mechanism according to the present invention, figure 2 Yes figure 1 The top view of the paper correction mechanism shown. Such as figure 1 with figure 2 As shown, the paper correction mechanism includes a correction roller assembly 1, a regulating roller assembly 2, a detection assembly 3, a first driving mechanism 5, a second driving mechanism 6 and a control mechanism (not shown in the figure).

[0033] Among them, the correcting roller assembly 1 is used to correct the skew of the medium; the adjusting roller assembly 2 is located downstream of the correcting roller assembly 1 along the medium conveying direction. When the adjusting r...

Abstract

The invention discloses a rectifying mechanism for sheet medium and medium treatment equipment with the rectifying mechanism. The rectifying mechanism comprises a rectifying roller component, an adjusting roller component, a sensor, and a control mechanism, wherein the rectifying roller component comprises a first driving roller and a paper pressing mechanism matched with the first driving roller; the sheet medium is arranged between the first driving roller and the paper pressing mechanism in a deflectable manner; the adjusting roller component is arranged downstream the rectifying roller component in the medium conveying direction, and comprises a second driving roller and a driven roller tangent to the second driving roller; the sensor is used for detecting the medium in a medium passage; and the control mechanism is used for control the rotation of the first driving roller and starting the rotation of the second driving roller in a time delay manner after the sensor detects the existence of the medium. The rectifying mechanism has the advantages that the structure is compact; and the deflection of the medium can be rectified within a very short transmission distance, which is favorable for device miniaturization.

Description

technical field [0001] The invention relates to a sheet medium deviation correcting mechanism and a medium processing device having the sheet medium deviation correcting mechanism. Background technique [0002] Existing sheet medium processing equipment, such as printers, scanners, currency detectors, etc., has a paper conveying mechanism, which is usually conveyed by a pair of rollers. The driving roller is composed of driven rollers that are tangentially matched. [0003] In order to adapt to as many media types as possible, the width of the conveying mechanism is often greater than the width of the media. Therefore, when the media is conveyed, the media may be skewed, which will cause inaccurate positions for printing, scanning and other media recording operations. cause a malfunction and cause inconvenience to the user. [0004] Chinese patent 200510121474.2 discloses a technical solution for media deviation correction. The deviation correction mechanism is fixed on th...
