Description
Technical Field
The utility model belongs to the technical field of printer, duplicator etc., especially, relate to a light source device that can be used to on printer, duplicator etc.
Background
most laser printers in the market have higher structural requirements, and all use a laser scanning unit combined by a combined lens as a light source, and irradiate light onto a photosensitive drum of a toner cartridge assembly at a corresponding position according to the irradiation requirements of the laser scanning unit. The laser scanning unit consists of a motor, a prism, a combined lens and a circuit board, the motor has high required precision, the prism and the combined lens have strict requirements on surface precision, curvature of each part of a curved surface and light transmittance, so that the laser has high cost, and meanwhile, due to the requirements of the prism and the combined lens, the requirements on the position of a photosensitive drum and the position of the laser are strict, so that the laser has high installation precision.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem that exists among the above-mentioned prior art, the utility model provides a can be used to light source device on printer/duplicator, this light source device simple structure does not need the lens combination of high accuracy, and the mode through the control light source lets the point on the light path board correspond the switch, realizes the output of data, has effectively improved and has printed duplicating speed and precision.
The technical scheme is as follows:
A light source device usable with a printer/copier, comprising: the light source is fixed on the light source support, the light source support and the light source are arranged in the outer cover, the light source control panel is fixed on the outer cover, the light source is connected with the light source control panel, the light source board is arranged on one side, opposite to the light source, of the light source, and the light source board is fixed on the outer cover.
The utility model has the advantages that:
a light source device for on printer/duplicator adopt simple light source unit structure, the light that its light source sent is normally open state, the digital signal of content will be printed to the light source control panel, becomes the signal of telecommunication, on exporting the light path board of light source unit, a light spot is launched to the light source, the point that the light path board corresponds is for leading to the state, light passes through this point, all the other points are unchangeable, for off-state, the state that here is dark, light is here blocked. The light source unit irradiates digital signals of contents to be printed onto the photosensitive drum, photoelectric images with light spots as units are formed on the drum, the contents to be printed are printed on the photosensitive drum by controlling the on and off of the spots on the light path board, and the spots on the light path board correspond to switches by controlling the light source, so that data output is realized, and the printing and copying speed and precision are effectively improved.

FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a diagram of the light path board for the light source direction projection of the present invention;
The reference numbers in the figures are as follows: 1-light source, 2-light path board, 3-light source bracket, 4-outer cover, 5-light source control board, 6-photosensitive drum, 7-light spot on the light path board.
Detailed Description
A light source device usable in a printer/copier is further described with reference to fig. 1-2.
A light source device usable with a printer, comprising: light source 1, light path board 2, light source support 3, dustcoat 4, light source control panel 5, light source 1 is fixed on light source support 2, place in light source support 2 and light source 1 in dustcoat 4, light source control panel 5 is fixed on the dustcoat 4, light source 1 with light source control panel 5 is connected, light path board 2 sets up one side that light source 1 is relative, light path board 2 is fixed on the dustcoat 4.
the method for controlling printing/scanning by the light source device comprises the following steps:
S1, the printer/copier converts the digital signal of the content to be printed into an electric signal and outputs the electric signal to the optical circuit board;
s2, the light source emits a corresponding light spot which irradiates the light path board;
S3, the point corresponding to the light path board irradiated by the light spot is in a through state, and the light passes through the point; the other points are in a disconnected state, and the light is blocked;
S4, the digital signal of the content to be printed is irradiated onto the photosensitive drum, and a photoelectric image in units of light spots is formed on the photosensitive drum.
The points of the light path board are arranged in a matrix, each line of light points corresponds to one line of points of the light path board, the rotating speed of the photosensitive drum is controlled according to the printing speed, and the longitudinal distance of the corresponding light points is a multiple of the speed of the corresponding light points.
a light source 1 in a light source unit is fixed on a light source support 3, the light source support 3 is arranged on an outer cover 4, a light path board 2 is fixed on the outer cover 4, a printer converts a digital signal of an image to be printed into an electric signal and outputs the electric signal to the light path board 2 of the light source unit, the light source emits a light spot, when the light spot irradiates on a point of the light path board 2, the corresponding point on the light path board 2 is in an on state, light passes through the point, the other points are unchanged, the light path board is in an off state, the light path board is in a dark state, and the light is blocked at the point. The light source unit thus irradiates the digital signal of the content to be printed onto the photosensitive drum 6, and a photoelectric image in units of light spots is formed on the photosensitive drum 6.
by controlling the on and off of the dots on the light path plate 2, the content to be printed is printed on the photosensitive drum 6. The light path board 2 is composed of points composed of an array matrix, the points have two states of on and off, the light is bright when the points are on, light can pass through, the light is dark when the points are off, the light is blocked, the corresponding light points are on and off, laser scanning contents are printed on the photosensitive drum 6, and laser printing is completed. Each line of light spots corresponds to one line, the rotation speed of the photosensitive drum is different according to the printing speed, the longitudinal distance of the corresponding light spots is a multiple of the speed of the photosensitive drum, and the multiple lines are adopted, so that the defects of the spots can be compensated, and the printing speed can be accelerated.
The novel light source device adopting the light source control mode has the advantages that the structure is simple, high-precision lens combination is not needed, the assembly cost and the manufacturing cost are reduced, the data can be output only by adjusting and controlling software control and enabling the point on the optical path board to correspond to the switch according to input data, the speed and the precision can be greatly improved, the flexibility of design schemes such as a printer and a copying machine is increased, and the cost and the manufacturing period are greatly reduced.
The above description is only the specific implementation manner of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can substitute or change the technical solution of the present invention and the design of the present invention within the technical scope of the present invention.
