Abstract
The invention relates to a toner detection device in a toner cartridge, specifically comprising a light incoming lens and a light outgoing lens, wherein the light incoming lens and the light outgoing lens have at least three branches and the branch ports are opposite to each other; the light incoming lens can divide the transmission light into a plurality of beams; and the light outgoing lens can combine the beams into one. Degree of attenuation of the average light beam of a plurality of beams of transmission light can reduce the error of light detection due to uneven distribution of the toner at the bottom of a powder bin during the working process of the toner cartridge, thus improving the accuracy of detection of the residual toner amount in the toner cartridge by a laser printer and saving the printing cost.
Description
Technical field
The present invention relates to the printing consumables field, especially a kind of cartridge that is used for laser printer.
Background technology
In the cartridge that laser printer uses, the toner detection device on the cartridge can detect the surplus of carbon dust in the cartridge automatically under the cooperation of laser printer.Its principle is: by toner detection device is installed on cartridge, the light that the generating laser of printer sends is injected lens through the light on the cartridge and is entered in the cartridge, light passes carbon dust arrival light ejaculation lens and penetrates in cartridge, arrive the light detection means on the laser printer then.Be positioned at the beam attenuation that carbon dust on the propagation path makes process, printer can be judged surplus powder information in the cartridge by the attenuation degree of metrology beam.
But in the existing toner detection device, it is single structure that light is injected lens, is positioned at the cartridge centre position.Light enters in the cartridge and can only propagate along intermediate path.When surplus powder in the cartridge fewer than half the time, rotation along with stirring vane on the puddle support in the cartridge, carbon dust also is transferred toward the developing chamber direction, the carbon dust this moment place, light ray propagation path of filling up powder storehouse bottom of capacity at once not, light attenuation is not enough and directly get back to the light receiving device of laser printer.Like this, even also have the carbon dust of capacity in the cartridge, printer also can be pointed out the information of the carbon dust deficiency in the cartridge, has influenced the accuracy that surplus powder detects, and has increased the Yu Fenliang in the cartridge, causes the increase of user's use cost.
Summary of the invention
The object of the invention is to design a kind of can the use on this class printer, and can accurately measure surplus powder amount in the cartridge, reduces the cartridge that the user prints cost.
To achieve these goals, technical scheme of the present invention is:
The toner detection device of this cartridge comprises that light is injected lens and light penetrates lens, and light injects lens and light ejaculation lens all are the lens that contain three branches at least, and structure is identical, and the port of each branch lenses is corresponding mutually.Concrete structure is: an end of lens is divided into three branch lenses at least.In optimized technical scheme, one end of lens is divided into three branch lenses: left end branch lenses, right-hand member branch lenses and medial fascicle lens, wherein left end branch lenses and right-hand member branch lenses have the first opposite turning in its bifurcation, and the back of turning round is vertical in the horizontal direction with former lens.The medial fascicle lens have medial fascicle lens turning in branch location, behind the turning perpendicular to the lens plane.Three branch lenses all have a reflecting surface in its corner, and reflecting surface and former lens and branch lenses maintenance miter angle, propagate along branch in lens in order to guarantee light.Also respectively there be second perpendicular corners on the extension of left end branch lenses and right-hand member branch lenses, parallel behind the turning with the medial fascicle lens.In second corner reflecting surface is arranged equally respectively, reflecting surface becomes miter angle in two outside surfaces of former lens, and its effect is to guarantee light propagation smoothly in lens equally.Distance between second turning of left end branch lenses and right-hand member branch lenses is slightly smaller than the width of cartridge.
Light injects lens and light penetrates bottom and the top that lens lay respectively at cartridge, the respectively generating laser of corresponding printer and the light detection means on the printer, and light is injected lens and light, and to penetrate the port of three branch lenses of lens corresponding mutually.Can guarantee that like this light enters cartridge and penetrates cartridge at the top in powder storehouse in the bottom in powder storehouse.Inject on the round of three branch lenses that lens and light penetrates lens corresponding one by one at light at light.
Description of drawings
Fig. 1 is that three branch's light are injected the lens synoptic diagram
Fig. 2 is that three branch lenses are in cartridge powder storehouse bottom schematic view
Fig. 3 is three branch lenses light path synoptic diagram in the cartridge
1 is the cartridge bottom among the figure; 2 inject lens for light; 3 are light ejaculation lens; 4 is the left end branch lenses; 5 is the medial fascicle lens; 6 is the right-hand member branch lenses; 41 is first turning of left end branch lenses; 42 is second turning of left end branch lenses; 51 is medial fascicle lens turnings; 61 is first turning of right-hand member branch lenses; 62 is second turning of right-hand member branch lenses
As shown in Figure 1, left end branch lenses 4 is vertical on in-plane with right-hand member branch lenses 6. Left end branch lenses 4 has first turning 41 in its bifurcation, in the extension second turning 42 is arranged, right-hand member lens 6 have first turning 61 in its bifurcation, and second turning 62 is arranged in the extension, medial fascicle lens 5 have medial fascicle lens turning 51 in branch location, perpendicular to lens plane.
As shown in Figure 3, light is injected lens 2 can be divided into three beams light to transmitted ray, and light penetrates lens 3 can be combined into Ray Of Light to three beams light. Meeting when puddle support is transported to the developing chamber direction to carbon dust is so that the carbon dust skewness of powder storehouse bottom 1, but the average light beam attenuation degree at three lens places can reduce the error in this light detection that brings because of the carbon dust skewness. The Yu Fenliang that detects of the light receiving system of laser printer can be more accurate like this.
Embodiment
As shown in Figure 3, the light beam that sends of the light launcher of laser printer sees through and is divided into independently light beam of three beams after light on the cartridge is injected lens 2.Left end branch lenses 4 divides light to left end, and right-hand member lens 6 divide light to right-hand member, propagate along intermediate path by the light of medial fascicle lens 5.Light beam about cartridge in three positions enter in the cartridge, the carbon dust in the powder storehouse makes its decay, three-beam after the decay synthesizes a branch of light through three branch lenses that light penetrates lens 3, and gets back to the light receiving device of laser printer.
