Method for controlling semi-automatic book and periodical scanner to complete manuscript pressing glass automatic lifting and automatic scanning process by adopting grating sensor

Abstract

The invention discloses a method for triggering and controlling a semi-automatic book scanner to complete automatic lifting and automatic scanning processes of a pressing frame by adopting grating sensors, which consists of a pair of grating sensors, a stepping motor, a clutch component, a position sensor and a manuscript glass pressing component, when the hands finish page turning and leave the grating sensor arranged in front of the operation platform, the manuscript pressing glass part can automatically press downwards, and after the manuscript pressing glass part is pressed downwards to a certain position to finish photographing or scanning, the manuscript pressing glass part ascends to automatically return to the initial position, so that the automatic lifting and automatic scanning process of the manuscript pressing glass part of the semi-automatic book and periodical scanner is finished; in the automatic lifting operation process of the glass pressing frame, if the grating sensor is triggered by hands, the glass pressing frame can automatically stop, and safety accidents such as hand clamping are prevented.

Description

Technical Field

[0001] The present invention is applied to a book scanner with a copy glass, and aims to solve the automatic lifting and scanning of the copy glass of the book scanner, and solve the safety problem of preventing hand pressure. Background Art

[0002] At present, the semi-automatic function of traditional book and magazine scanners with a copy glass includes two functions: automatic pressing down and raising of the copy glass and automatic triggering of scanning. The completion of the triggering of the semi-automatic function mainly relies on button triggering. This triggering method is not automatic and is not advanced enough. Summary of the Invention

[0003] In view of the fact that the traditional semi-automatic book and periodical scanner with a draft glass cannot automatically trigger the automatic depression and rise of the draft glass, the present invention has designed a mechanism consisting of a pair of grating sensors 5, a stepper motor 6, a clutch component 7, a position sensor 8 and a draft glass component 3. During operation, when the operator manually opens a bound paper document 9 and the hand retracts away from the facing position of the two grating sensors 5, the semi-automatic function is triggered, and the draft glass component 3 is pressed down against the paper surface, flattening the paper and triggering the scanning function. After the scanning is completed, the draft glass component 3 rises back to the initial position, thereby realizing the semi-automatic function of the book and periodical scanner. At the same time, during the operation of the draft glass component 3, if human hands or other objects enter the position of the grating sensor 5, the stepper motor 6 will be triggered to stop rotating, thereby also playing a safety protection function.

DETAILED DESCRIPTION

[0005] Combined with the drawings of the specification, the present invention is mainly applied to a book and periodical scanner with a draft glass. The scanner generally mainly comprises a scanning head, a column component, a draft glass component, an operating platform base, a grating sensor, a stepping motor, a clutch, a support plate component, etc. The clutch component 7, the stepping motor 6, the V-shaped support plate component 9, and the column component 2 are mounted on the operating platform base 4, the scanning head 1, the draft glass component 3, and the position sensor 8 are mounted on the column component 2, the grating sensor 5 is mounted on the operating platform base 4, and is located at an appropriate position in front of the draft glass component 3, one on each side, and the stepping motor 6 uses a stepper belt to drive the clutch 7, and the clutch 7 is connected to the draft glass component with a belt. During operation, when the operator opens the bound paper document 9 by hand and the hand retracts from the shooting position of the two grating sensors 5, the grating sensor 5 is triggered, and then the stepper motor 6 rotates. At the same time, the clutch 7 is attracted, and the draft glass component 3 is driven to move up and down, thereby completing the automatic functions of pressing down, scanning, and returning. During the lifting and lowering movement of the draft glass component 3, if an object (including a human hand) enters the shooting position of the grating sensor 5 from the front, the lifting and lowering movement of the draft glass component 3 will be automatically stopped.

Claims

1. A book scanner with a press glass uses a grating sensor as a trigger element to control the semi-automatic book scanner to complete the automatic lifting and automatic scanning process of the press glass, which is characterized by: A grating sensor is used as a trigger element, which drives the rising and falling of the copy glass in cooperation with driving elements such as a stepping motor and a clutch component.

2. According to the mechanism of claim 1, the time point when the grating sensor triggers the automatic lifting of the manuscript glass is: the operator's hand retracts after turning the page until it leaves the position of the grating sensor's corresponding surface.

3. According to the mechanism described in claim 1, the grating sensor is also multifunctional. In addition to being a trigger element, it can also play a safety protection role during the automatic lifting and lowering of the copy glass.

4. The mechanism according to claim 1, its applications include but are not limited to various paper document scanners with glass pressing.
