ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a dispenser and particularly, to a media dispenser capable of driving a whole system and using various kinds of media.
2. Description of the Background Art
A conventional media dispenser comprises a media cassette in which media are stored, a feeding module
204
to which the media stored in the media cassette
202
, a sensing unit
206
sensing whether two 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 collecting media when two 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
respectively.
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 a 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
.
If the thickness sensing unit
206
senses the thickness of the media fed through the feeding module
204
and if two sheets of media are fed together, it feeds media to the reject box.
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 collects the media in case two sheets of inferior media are fed together and feeds the media to the reject box
210
via a specific process. Such delivery module
208
comprises 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 sheets of media are passed together.
The media fed to the delivery module
208
are fed to the discharging part
222
which is capable of providing the media to the user by the plurality of rollers and belts and inferior media or media in case two or more sheets of media are transmitted are collected to the reject box
210
.
However, the conventional media dispenser requires the first driving motor for driving the media separating part to separate the media from the media cassette and the second driving motor for driving the feeding module and the delivery module. Namely, there is a problem due to using a plurality of motors of relatively high cost.
Also, since the conventional media dispenser can load only one media cassette, predetermined kinds of media can be loaded and since different kinds of media can not be treated, usefulness is reduced and there is a disadvantage that an additional media dispenser is needed to treat different kinds of media.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide 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 media dispenser comprising a base plate in which a media cassette in which media are stored and a rejected box are loaded, a media pickup part installed at the lower side of the base plate for discharging the media stored in the media cassette by separating sheet by sheet, a media feeding part for feeding the media discharged through the media pickup part, a media discharging part for discharging the fed media through the media feeding part to outside, a driving means installed at one side of the base plate for generating driving force, a power transmitting means for transmitting the driving force generated at the driving means to the media pickup part, media feeding part and media discharging part, a clutch means installed at one side of the media pickup part for controlling the driving force transmitted to the media pickup part from the power transmitting part and a media rejection means for separating and collecting abnormal media among media fed to the media feeding part.
The dispenser in accordance with the present invention further includes a plurality of sub media cassette units installed at one side of the base plate for loading driving force from the driving means, storing the media different from those stored in the media cassette and discharging them through the media discharging part.
The base plate has an interior loading space for loading the media cassette at the front side, another interior loading space for loading a reject box for loading inferior media at the upper side of the above interior loading space and a door at the front side of the two interior loading spaces.
A locking system for preventing an arbitrary external access is installed at the door.
A cushion member abutted on the front surface of the media cassette for buffering impact or vibration generated when the media are discharged from the media cassette is installed on the inner side surface of the door.
The driving means is a driving motor installed at one side of the base plate for generating rotational force.
The power transmitting means comprises a driven pulley connected by a driving pulley and driving belt, which are installed in a driving motor, a lower connection pulley connected by the driven pulley and timing belt, for driving the media pickup part and media feeding part and an eject pulley wound by the driven pulley and timing belt, for driving the media feeding part and media discharging part.
The media pickup part comprises a pickup roller positioned at the lower side of the base plate, for discharging the media stored in the media cassette in the lower direction by friction, a feeding roller and separating roller positioned at the lower side of the pickup roller, for feeding the media discharged by the pickup roller by separating the media sheet by sheet and a guide member for guiding the media fed through the feeding roller and separating roller to the upper direction.
The pickup roller separates and discharges the media using friction of the media and accordingly is formed to receive power from the feeding roller due to having a rubber part at a certain part of the circumferential surface.
The separating roller rotates in the same direction as the feeding roller and is connected to the feeding roller and a connection belt.
The guide member is formed to have a certain curvature at the lower side of the feeding roller and the separating roller and a connection guide for guiding the media passed through the guide member to the media feeding part at the end portion of the guide member.
The connection guide has one side surface abutted to the guide member, slopping upward and anoth
