Abstract
The utility model discloses a kind of cover plate of duplicating machine component, include the cover board of duplicator, lamp plate layer is provided with below the cover board, light source device is provided with lamp plate layer, light source device and the duplicator internal electric source is electrically connected, and the lamp plate layer is arranged with dimmer board.It can effectively reduce the situation that " black surround " occurs in copy.
Description
Technical field
A kind of copier is the utility model is related to, more particularly to a kind of cover plate of duplicating machine component.
Background technology
Duplicator is the equipment for the autotype for obtaining equimultiple from the original copy of writing, drafting or printing, zooming in or out.Duplicate
The speed that machine duplicates is fast, and easy to operate, the main distinction with traditional letter press, paraffin paper mimeograph, offset printing etc. is to need not move through
The intermediate meanses such as other plate-making, and directly autotype can be obtained from original copy.
When using duplicator thicker file, since the object duplicated is too thick, cover plate of duplicating machine can not press tightly,
By hollow around hard-copy file, " black surround " phenomenon occurs on the copy for causing to run off, i.e., the position not pressed to is shown
Black is shown, influences the effect of copy.
The content of the invention
The purpose of this utility model is to provide a kind of cover plate of duplicating machine component, it can effectively reduce copy appearance
The situation of " black surround ".
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of cover plate of duplicating machine component, includes the cover board of duplicator, is provided with lamp plate layer below the cover board, in lamp plate layer
Light source device is provided with, light source device and the duplicator internal electric source is electrically connected, and the lamp plate layer is arranged with dimmer board.
The lamp plate layer and dimmer board are embedded in cover board bottom and the lower surface of the dimmer board and protrude from cover board.
Electromagnet is provided with the cover board, the lamp plate layer upper surface is provided with iron plate layer.
Pass through transparent viscose or screw connection between the lamp plate layer and dimmer board.
The size of the lamp plate layer is less than or equal to the size of cover board, and the size of the dimmer board is consistent with lamp plate layer.
The light source device is LED lamp bead.
The dimmer board is acrylic board.
In conclusion the utility model has the advantages that：
1st, light filling is carried out to the periphery for needing hard-copy file with light source device, so as to reduce tight and output because that can not press
" black surround " phenomenon；
2nd, connected and fixed by magnetic between lamp plate layer and cover board, convenient dismounting and replacement.
Brief description of the drawings
Fig. 1 is the schematic diagram that embodiment one is used to embody connection structure between cover board and lamp plate layer；
Fig. 2 is the schematic diagram that embodiment one is used to embody LED lamp bead positional structure in lamp plate layer；
Fig. 3 is that the present embodiment two is used for body electromagnet and the schematic diagram of iron plate layer positional structure.
In figure, 1, cover board；11st, electromagnet；2nd, lamp plate layer；21st, LED lamp bead；22nd, iron plate layer；3rd, dimmer board.
Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one, a kind of cover plate of duplicating machine component, as illustrated in fig. 1 and 2, includes the cover board 1 of duplicator, the lower section of cover board 1
Lamp plate layer 2 is embedded with, array is provided with LED lamp bead 21 in lamp plate layer 2, and LED lamp bead 21 is connected with the power supply inside duplicator, and
And switch is set on the control panel of duplicator, lamp plate layer is fixedly connected with for 2 times transparent by transparent viscose or screw
Dimmer board 3, its material use acrylic board, and the lower surface of dimmer board 3 protrudes from the bottom of cover board 1 or the bottom with cover board 1
While flush；The size of lamp plate layer 2 is not more than the size of cover board 1, and the size of dimmer board 3 is consistent with the size of lamp plate layer 2.
Specific implementation is described as follows：
Cover board 1, lamp plate layer 2 and 3 integrally connected of dimmer board are set, convenient and practical, easy to operate.When the file that needs duplicate
When more thick and heavy, LED lamp bead 21 is opened by switch on control panel, light filling is carried out to the periphery of file, thus reduce because
It can not press tightly and " black surround " phenomenon of output.
Embodiment two, a kind of cover plate of duplicating machine component, as shown in figure 3, the difference of itself and embodiment one is, cover board
Electromagnet 11 is provided with 1 and by duplicator in-line power, 2 upper surface of lamp plate layer is provided with iron plate layer 22, cover board 1 and lamp plate
Realize that connection is fixed by 11 adsorpting iron plate layer 22 of electromagnet between layer 2.
Such advantage is, realizes the dismounting and fixation to lamp plate layer 2 by switch electromagnet 11, facilitates lamp plate layer
2 maintenance and replacement.
The operation principle of duplicator is that the optical analog image of original copy is passed through optical system by way of exposure scan
Be projected directly in photosensitive drums, produce electrostatic latent image, then by other processing and etc. complete whole copying process.Occur " black
The basic reason on side " is because the slit source that the light of some can be between cover board and host when thicker object exposes
Go out, be damaged the light that photosensitive drums receive, and then " black surround " phenomenon occur.Therefore to eliminate black surround, the utility model device makes
Closely light filling is carried out to the photosensitive drums that part is not covered with by duplicating object with light source.And it is further, in order to enable supplement
Light distribution it is more uniform, increase by one layer of dimmer board.Acrylic board and LED lamp bead are the material for being easier to obtain at this stage
Material, therefore as the preferred embodiment of the utility model device.
It should be noted that the utility model is not limited only to be used for duplicator.Printer with copy function, or other
Copier, can also use cover plate assembly provided by the utility model.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, ability
Field technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but
As long as all protected in the right of the utility model be subject to Patent Law.
