Fig. 3 is the flow chart of the medium transport control method according to the embodiment of the present invention, and the method comprises following processing procedure:
Step S101, judges that whether main power source is abnormal
Whether the output voltage V1 that main power source 111 is detected in power state detection portion 12 is in real time less than predeterminated voltage, if out-put supply V1 is less than predeterminated voltage, then export main power voltage abnormal signal, as signal " 0 ", after controller 10 receives the electric voltage exception signal of power state detection portion 12 transmission, judge that main power source is abnormal; If out-put supply V1 is not less than predeterminated voltage, then export main power voltage normal signal, as signal " 1 ", controller 10 judges that main power source is normal, continues the output signal detecting power state detection portion 12.
Step S102, is powered to media conveying mechanism by stand-by power supply
When controller 10 judges that main power source 111 is abnormal, when namely main power voltage is less than predeterminated voltage, powered from trend media conveying mechanism 13 by stand-by power supply 112.
Step S103, control medium conveying mechanism performs medium transport action under the power supply of stand-by power supply
Stand-by power supply 112 is powered to the medium transport motor 131 of media conveying mechanism 13, and medium transport motor 131 drives feed roller assembly 132 to rotate, and is expelled to outside medium conveying apparatus by the medium in medium conveying apparatus, so that user takes away.
If medium conveying apparatus only has one for the opening of medium inlet and outlet, then the motor 131 of controller 10 control medium conveying mechanism drives feed roller assembly 132 to rotate along paper delivery direction, and drive medium is discharged from this opening; If medium conveying apparatus has an entrance and an outlet, then the motor 131 of controller 10 control medium conveying mechanism drives feed roller assembly 132 to be rotated further, and drive medium is discharged from outlet.
In the medium transport control method of this embodiment, owing to can be powered to media conveying mechanism 13 by stand-by power supply 112 when main power source 111 is abnormal, thus media conveying mechanism 13 can perform medium transport action under the power supply of stand-by power supply 112, the medium be in transfer passage is discharged.
Preferably, when main power source is abnormal, if be not detained medium in medium conveying apparatus, then can without the need to by stand-by power supply to media conveying mechanism power and control medium conveying mechanism under the power supply of stand-by power supply, perform medium transport action, that is, only abnormal and just to be powered to media conveying mechanism by stand-by power supply and perform medium transport action under the power supply of control medium conveying mechanism at stand-by power supply when being detained in medium conveying apparatus and having medium at main power source.Thus, in embodiments of the present invention, after judging that whether main power source is abnormal, can also comprise and judge in medium conveying apparatus, whether to be detained the step having medium.
In order to improve availability and the user friendly of medium conveying apparatus further, can also after judging that main power source is abnormal, export information prompting user medium conveying apparatus abnormity of power supply, be convenient to prompting user medium conveying apparatus break down, prevent user from carrying out unnecessary operation.
Fig. 4 is the flow chart of medium transport control method according to the preferred embodiment of the invention, and as shown in Figure 4, this medium transport control method comprises:
Step S201, judges that whether main power source is abnormal
With step S101.
Step S202, judges whether to be detained in medium conveying apparatus have medium
An entrance is comprised below and an outlet illustrates the medium how judging whether to comprise delay in medium conveying apparatus for medium conveying apparatus.Detect medium by the output signal of inlet sensor and whether enter medium conveying apparatus, detect by the output signal of outlet transducer the medium entering medium conveying apparatus whether to discharge from medium conveying apparatus, jointly judge whether be detained medium in medium conveying apparatus by inlet sensor and outlet sensor output signal.
If inlet sensor does not detect medium always, represent that medium does not enter medium conveying apparatus, be not namely detained medium in medium conveying apparatus.
If inlet sensor detects medium, represent that medium enters medium conveying apparatus, be namely detained medium in medium conveying apparatus.
If outlet transducer detects medium, represent that the medium entering medium conveying apparatus is discharged from medium conveying apparatus, be namely detained medium in medium conveying apparatus.
When inlet sensor and outlet transducer all do not detect medium, output signal change according to inlet sensor judges whether medium enters medium conveying apparatus, and the output signal change according to outlet transducer judges whether the medium entering medium conveying apparatus discharges.When setting medium is positioned at the detection position of inlet sensor, the output signal of inlet sensor is " 1 ", otherwise the output signal of inlet sensor is " 0 "; When medium is positioned at the detection position of outlet transducer, the output signal of outlet transducer is " 1 ", otherwise the output signal of outlet transducer is " 0 ".When the change from " 0 "-> " 1 "-> " 0 " occurred for the output signal of inlet sensor, namely detect medium grow out of nothing arrive again without time, represent that medium enters medium conveying apparatus.When medium enters medium conveying apparatus, if there is the change from " 0 "-> " 1 "-> " 0 " in the output signal of outlet transducer, namely detect medium grow out of nothing arrive again without time, represent that the medium entering medium conveying apparatus is discharged in medium conveying apparatus, be not namely detained medium in medium conveying apparatus; If outlet transducer does not detect medium always, and medium length Lm is in the direction of movement less than the distance Lb between inlet sensor and outlet transducer, represent that the front end having entered the medium of medium conveying apparatus does not arrive outlet transducer, namely medium is detained in medium conveying apparatus, wherein, Lm=Vm*T, Vm are the transporting velocity of medium, and T is the cumulative time that medium front end arrives that inlet sensor leaves inlet sensor to medium tail end.
If be detained medium in medium conveying apparatus, then forward step S203 to; If be not detained medium in medium conveying apparatus, then this medium transport control procedure terminates.
Step S203, stand-by power supply drive medium conveying mechanism discharges the medium be detained in medium conveying apparatus
This step can be realized by the step S102 in above-described embodiment and step S103.
Step S204, sends information
After controller 10 receives the main power source 111 abnormity of power supply signal of power state detection portion 12 output, send corresponding information, as shown information such as " main power source power down " on liquid crystal display 16, or send the prompting of corresponding light by LED light 17, prompting user breaks down.
In the medium transport control method that this embodiment provides, when main power source is abnormal, conveying mechanism is driven to discharge the medium be trapped in medium conveying apparatus by stand-by power supply, therefore, do not need the help of staff, user just directly can take the medium be detained in medium conveying apparatus away, improve the ease for use of medium conveying apparatus, by prompting user medium conveying apparatus abnormity of power supply, be convenient to prompting user medium conveying apparatus break down, prevent user from carrying out unnecessary operation, improve availability and the user friendly of medium conveying apparatus.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
