ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dispenser and particularly, to a control system and a method of a media dispenser capable of driving a whole system using a driving source and recollecting abnormal media in the whole period of the media feeding path.
2. Description of the Background Art
FIG. 1
is an elevational view showing a conventional media dispenser.
A conventional media dispenser includes a media cassette
202
in which media are stored, a feeding module
204
to which the media stored in the media cassette
202
is fed, a sensing unit
206
sensing whether two or more sheets of media are fed together by sensing the thickness of the media fed through the feeding module
204
, a delivery module
208
for transmitting the media passed through the thickness sensing unit
206
to a user and a reject box
210
for recollecting media when two or more sheets of media are fed together in the thickness sensing unit
206
.
In the media cassette
202
, a media separating part
212
for separating media into each sheet to transmit the stored media into the feeding module
204
is respectively provided.
Here, the media separating part
212
is connected to the first driving motor
214
installed at one side of the feeding module
204
and is operated by receiving driving force of the first driving motor
214
.
The feeding module
204
feeds the media transmitted from the media cassette
202
to the thickness sensing unit
206
and is composed of a plurality of pulleys
216
, belts
218
and a plurality of rollers
220
.
The thickness sensing unit
206
detects whether two or more sheets of media are fed together by sensing the thickness of the media fed through the feeding module
204
.
The delivery module
208
has a discharging part
222
to supply the media passed through the thickness sensing unit
206
to the user and it recollects the media in case two or more sheets of abnormal media are fed together and feeds the media to the reject box
210
via a specific process. Such delivery module
208
includes a plurality of pulleys
226
, belts
224
and a plurality of rollers
228
.
The pulleys and belts of the feeding module
204
and delivery module
208
are driven by the second driving motor
230
installed at one side of the delivery module
208
. Namely, the second driving motor
230
is connected with a driving pulley
232
and the driving pulley
232
is connected to the driven pulley
236
and belt
234
. The driven pulley
236
is connected to each pulley by the belt and transmits the driving force.
In the conventional media dispenser, the media stored in the media cassette
202
are separated to sheet by sheet by the media separating part
212
and transmitted to the feeding module
204
if the first driving motor
214
is driven. If the second driving motor
230
is driven, the feeding module
204
and the delivery module
208
are driven. Then the media transmitted to the feeding module
204
are fed to the thickness sensing unit
206
by the plurality of pulleys and belts and transmitted to the delivery module
208
after the thickness sensing unit
206
senses whether two or more sheets of media are passed together.
The media fed to the delivery module
208
are fed to the discharging part
222
capable of providing the media to the user by the plurality of rollers and belts and abnormal media or media in case two or more sheets of media are transmitted are recollected to the reject box
210
.
However, since the conventional media dispenser is capable of positioning only one media cassette and dispense only predetermined kind of media, additional media dispensers need to be purchased to dispense another kinds of media.
Namely, since sizes of currencies in respective countries are different in case currency is used as the media, the media can not be used in another countries thus to limit the usefulness.
Also, the media can not be recollected in case a power supply is interrupted in use or the media are blocked by erroneous operation in the media feeding path. Accordingly, the system must be reassembled after taking apart the system and taking away the media thus to cause inconvenience and lengthen the operation time.
Also, since the first driving motor for driving the media separation part and the second driving motor for driving the feeding module and the delivery module to separate the media from the media cassette are needed, there was a problem of increasing the manufacturing cost due to using a plurality of motors of relatively high cost.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide a control system and a method of a media dispenser capable of reducing cost and simplifying structure by driving a whole system using a driving means.
Another object is to provide a media dispenser capable of treating various kinds of media by installing various kinds of media selectively thus to broaden the usefulness.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a control system of a media dispenser comprising a driving motor installed at one side of the base plate in which a media cassette is positioned, for generating driving force, a clutch installed at one side of a media pickup part which discharges media stored in the media cassette and connected to the driving motor, for selectively transmitting the driving force generated in the driving motor to the media pickup part and a clutch controlling means for controlling operation of the clutch by turning on/off a power source applied to the clutch to consequently discharge the media from the media cassette.
The clutch is formed using the solenoid method which transmits or cuts off the power to or from the media pickup part according to the on/off of the power source.
The clutch controlling means includes a feed sensor installed at one side of the media feeding part to which the media discharged from the media pickup part are fed, for sensing passage of the media, an eject sensor installed at one side of a media discharging part from which the media fed through the media feeding part are discharged to outside, for sensing the media discharged to the media discharging part and a controlling part for turning off the clutch according to electric signals applied from the feed sensor and turning on the clutch according to signals applied from the eject sensor.
The feed sensor includes a light-emitting part installed at a certain position in the media feeding part, for irradiating light and a light-receiving part positioned at a certain interval with the light-emitting part, for sensing light irradiated from the light-emitting part and transmitting the electric signal to the controlling part and counts the number of media being fed and generates clutch-off signals.
The eject sensor includes a light-emitting part installed at one side of the passage in which the media of the media discharging part, for irradiating light and a light-receiving part positioned at a certain interval with the light-emitting part, for sensing light irradiated from the light-emitting part, counts the number of media being discharged through the media discharging part to outside and generates clutch-on signals.
The control method of the media dispenser includes a first step of discharging the media stored in the media cassette by the operation of the media pickup part after the driving motor is driven and the clutch is turned on by applying a power from a power supply unit, a second step of determining whether the media discharged from the media cassette is reached to the first point which is a certain position of the media feeding part while the media are fed though the media feeding part, a third step of cutting-off a driving force transmitted to the media feeding part by turning off the clutch if it is judged that the media reach to the first point, a fourth step of judging whether the media passed through the first point reach to the second point of th
