Abstract
The invention relates to an image reading device, in particular to a contact-type image sensor. The contact-type image sensor is provided with a frame; a circuit board is arranged below the frame; a photovoltaic conversion chip is arranged on the circuit board; lenses are arranged above the photovoltaic conversion chip; one sides or both sides of the lenses are provided with light sources; and a glass plate is arranged above the frame. The contact-type image sensor is characterized in that at least two rows of lenses with different angles or at least two rows of light sources with different angles are arranged, so that included angles between the light emitting center of each row of the light sources and the centers of the lenses are different, or included angles between the light emitting centers of the light sources and the center of each row of lens are different; two rows of light sources with different angles can be formed by at least two rows of light sources and the angles of the light emitting centers of the two rows of light sources are different; and two rows of light sources with different angles can also be formed by one row of light sources and at least two light emitting grooves with different angles are arranged on each light source, so that the same row of light sources emit at least two angles of light to identify anti-counterfeiting image information on paper money, such as sympathetic ink denomination numbers, holograms and the like, which can be displayed in different colors or patterns at different angles.
Description
Technical field
The present invention relates to the reading device of image, at length say it is a kind of contact-type image sensor that multi-angle reads that has.
Background technology
We know, the basic structure of contact-type image sensor is below framework, to be provided with wiring board; Wiring board is provided with the opto-electronic conversion chip, and opto-electronic conversion chip top is equipped with lens, and the side of lens is provided with light source; Light source can be located at a side of lens; Also can be located at the both sides of lens, the framework top is provided with the glass plate that carries picture original, and the existing contact imageing sensor has only a kind of reading angular usually.Expansion along with application; Function to contact-type image sensor proposes increasing requirement; Like many places anti-counterfeiting information on the banking system bank note false distinguishing facility identification bank note, color shifting ink denomination numeral wherein, hologram etc. all are can see various colors or pattern anti-fake image information with different angles.
Summary of the invention
Technical problem to be solved by this invention is: multiple reading angular is provided, can realizes requiring to read with different angles the contact-type image sensor of the false distinguishing recognition function of different images.
The present invention's technical scheme that is adopted of dealing with problems is:
A kind of contact-type image sensor is provided with framework, and the framework below is provided with wiring board; Wiring board is provided with the opto-electronic conversion chip, and opto-electronic conversion chip top is equipped with lens, and lens one side or both sides are provided with light source; The framework top is provided with glass plate; It is characterized in that being provided with at least the lens of two row different angles or the light source of at least two row different angles, make the angle of luminescence center and lens centre of every row light source inequality, or the angle of the luminescence center of light source and every row lens centre is inequality; Angle according to anti-counterfeiting image needs on the picture original is carried out the different combinations conversion, to adapt to the different anti-counterfeiting image information that show different colours or pattern of scanning angle.
It is according to the invention that the light source of two row different angles is arranged can be at least two row light sources; The luminescence center angle of every row light source is inequality; It also can be a row light source; At least be provided with the luminous groove of two kinds of different angles on the light source, make same row light source send the light of at least two kinds of angles, to adapt to the different anti-counterfeiting image information that show different colours or pattern of scanning angle.
The present invention can carry out the different combinations conversion according to the angle of anti-counterfeiting image needs on the picture original, can show the anti-counterfeiting image information of different colours or pattern with different angles with the color shifting ink denomination numeral on the identification bank note, hologram etc.
