Then, motor 70 is along opposite spin, driving first gear 71 and idler gear 72, and then drives second gear 73.Conveying roller 15 drives by means of rotatablely moving of second gear 73, and therefore, paper is placed in the position that is fit to printing.
Above-mentioned traditional configuration needs to use a large amount of idle pulleys, so require a large amount of parts, causes assembling process complicated, thereby reduces reliability of products.In addition, also need a sensor 95, after semilune intake roller 90 rotates a circle, determine its appropriate location, finally make the control circuit of printing complicated.
According to my research to current these samples, I think that people need as this improved full-automatic inlet device among the present invention.
One object of the present invention just provides a kind of automatic paper feeder that is used for printed apparatus.
Another object of the present invention provides a kind of simple in structure, automatic paper feeder that size reduces.
A further object of the invention is exactly by simplifying transmission mechanism, can reduce the required time of paper feed operation.
For reaching above and other purpose, the invention provides a kind of automatic paper feeder that is used for printed apparatus.Aforesaid this device is equipped with a motor, is used for producing and transferring power.A pair of idle pulley is meshed with the both sides of idler gear, and idler gear is meshed with a gear on being connected to motor shaft.One of idle pulley is with being meshed with lock moving gear and coaxial mounted other idle pulley of intake roller travelling gear.The groove that has a circular with the moving gear of locking is used to install elastic ring.
Aforesaid another idle pulley has an axle, and this stretches out from the inside circumference near its gear teeth.
Above-mentioned axle is being equipped with the untie-sell of a lock near the idle pulley inner surface portion.A fin also is housed in the position relative with axle.Fin is vertical with the direction of axle.
An all-in-one-piece ridge is with it arranged on the fin.This ridge can be collided with a flanging of above-mentioned ring, throws off or the untie-sell of pinning lock according to the direction of rotation that is installed in the gear on the same axle, thereby can control the intake roller travelling gear.
In conjunction with the accompanying drawings, referring to following detailed description, can more fully understand the present invention, and can understand its attendant advantages better, identical Ref. No. is represented same or analogous parts among the figure, wherein:
