Abstract
The invention relates to an original exposure device used in an image reader for a copying machine, printer, scanner, etc. A toothed belt 5 for reciprocating carriages 1 and 2 are extended between a pair of spur pulleys 6, to turn the surfaces of teeth to the outside of a loop, and a toothed driving pulley 8 fitted on the shaft of a driving motor 7 is pressed on the toothed belt 5 to drive in a state where the teeth of the belt 5 and the driving pulley 8 are engaged. As the pulleys except the toothed driving pulley 8, the spur pulleys are provided to prevent the generation of the engagement frequency of the toothed pulley.
Description
Technical field
The present invention relates to use at duplicating machine, printer, scanning machine etc. and comprise the fixed manuscript exposure device of document board in the device of image read-out.
Background technology
In the past, it is disclosed like that this manuscript exposure device, for example spy open clear 62-42142 communique, be installed on the cingulum being provided with the exposure portion of optical pickup device and the vehicle frame of catoptron portion, on belt pulley with tooth that hangs on the motor drive shaft of being located at CD-ROM drive motor of this cingulum, the other end hangs over from employing on the belt pulley with tooth, by the CD-ROM drive motor revolution, makes the cingulum revolution, vehicle frame to-and-fro movement, said structure are general patterns.
In the disclosed manuscript exposure device that is called as the scanning mirror mode of above-mentioned communique, power from CD-ROM drive motor is delivered to cingulum by the driving side belt pulley with tooth that is installed on the motor drive shaft, vehicle frame is moved for scanning, on structure, the slave end belt pulley also is necessary for the toothed member that is meshed with the tooth of cingulum.Though this slave end belt pulley does not have actual relationship with the drive actions of vehicle frame,, from such driven pulley meshing frequency (vibration) and hot-tempered sound can take place sometimes.On in recent years duplicating machine etc., along with the high-resolutionization of image, especially meshing frequency probably can cause occurring on the image ribbon grain, can not ignore.
Summary of the invention
The present invention the objective of the invention is in view of the existing problem of above-mentioned prior art puts forward, and a kind of manuscript exposure device that makes the driving of cingulum with meshing frequency (vibration) beyond the belt pulley and the disappearance of hot-tempered sound is provided.
To achieve these goals, the present invention proposes a kind of manuscript exposure device, is the fixed manuscript exposure device of document board, and by the cingulum of ring-type, the exposure portion and the reflective mirror portion that drive optical pickup device move toward the direction of scanning; It is characterized in that: the anodontia back side that makes above-mentioned cingulum is hung between a pair of supporting mass towards the inboard of ring, makes drive unit and flank engagement towards this cingulum outside.
Manuscript exposure device described in according to the present invention, its feature also are, above-mentioned cingulum is hung on the stationary shaft of the pair of cylinders shape that forms above-mentioned supporting mass.
According to manuscript exposure device of the present invention, its feature also is, above-mentioned cingulum is hung on the stationary shaft of a pair of semicircle tubular that forms above-mentioned supporting mass.
According to manuscript exposure device of the present invention, its feature also is, above-mentioned cingulum is hung on a pair of sliding bearing or rolling bearing that forms above-mentioned supporting mass.
According to manuscript exposure device of the present invention, its feature is that also the position of engagement that makes above-mentioned drive unit and above-mentioned cingulum is between above-mentioned a pair of supporting mass.
According to manuscript exposure device of the present invention, its feature also is, the position of engagement that makes above-mentioned drive unit and above-mentioned cingulum is such position: this drive unit is set at the position with some subtends of above-mentioned a pair of supporting mass, and above-mentioned cingulum is by between them.
The following describes effect of the present invention.
Manuscript exposure device according to the present invention's proposition, as mentioned above, because the flank of tooth of cingulum is towards the outside of ring, so, the engagement of the tooth that is used to drive can only be the band tooth drive pulley on the motor shaft, except the belt pulley that is used to hang cingulum of above-mentioned drive pulley can be a flat-belt pulley, therefore, the meshing frequency (vibration) that can prevent driven pulley takes place, can alleviate unstable and the lens that vibration causes and the vibration of mirror system integral body, can obtain preferable image because of vehicle frame speed.In addition, owing to can use a plurality of flat-belt pulleies, not only reduced part expense and metal pattern making expense in addition, and, because the tooth of cingulum and belt pulley engagement operation has only drive division one place during assembling, significantly reduced between the tooth and interfered the bad and activity duration of caused assembling.
Another kind of pattern according to said apparatus, as mentioned above, because cingulum is hung on the stationary shaft of pair of cylinders shape, on above-mentioned Joint effect basis, also having needs flat-belt pulley hardly thereby can reduce other number of packages and installation time, the effect that reduces the cost.
According to another pattern of said apparatus, as mentioned above,, except the effect that above-mentioned cylindric stationary shaft had, also has the effect that reduces weight and fee of material because cingulum is hung on the stationary shaft of a pair of semicircle tubular.
Another pattern according to said apparatus, as mentioned above, because cingulum is hung on a pair of sliding bearing or the rolling bearing, on above-mentioned Joint effect basis, even tension force increases radial load and becomes big on the cingulum, owing to the external diameter and the foreign steamer of sliding bearing or rolling bearing are used as belt pulley, have the effect that can realize that high sliding, small-sized and cheap band drive.
