Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a media cassette for an automatic dispenser such as a paper currency dispenser and particularly, to a media cassette for an automatic dispenser in which a push plate locking latch in the media cassette is automatically unlatched when the media cassette is received in the automatic dispenser.

2. Description of the Background Art

Generally, an automatic dispenser is applied to automatic teller machines (ATMs). An ATM generally is provided with a space for receiving a media cassette to store cash (paper currency) which is a medium and with a door for locking the media cassette after receiving the media cassette therein.

FIG. 1 is a top plan view showing a conventional media cassette for an automatic dispenser and FIG. 2 is a front view showing the conventional media cassette for an automatic dispenser.

The conventional media cassette for the automatic dispenser includes a cassette body 102 having an interior space in which media may be stored, a push plate 104 installed slidably in the cassette body 102 for supporting media received in the cassette body 102 , a spring 106 positioned between the push plate 104 and an inside wall of the cassette body 102 for urging the push plate 104 , and a guide installed between the push plate 104 and the cassette body 102 for slidably supporting the push plate 104 .

The cassette body has a rectangular shape with the one side opened and a guide line 108 which is slid at the upper side when the media cassette is installed in the automatic dispenser.

The push plate 104 is positioned movably in the cassette body 102 standing upright and at the one upper end of the cassette body, a handle 110 is formed which a user can hold and pull out. As mentioned between the rear surface of the push plate 104 and the inner rear wall surface of the cassette body 102 , a spring 106 is installed to provide an elastic force to the push plate 104 .

The guide includes a guide rails 112 which are installed on the both inner side walls of the cassette body 102 in the longitudinal direction thereof and guide rollers 114 which are installed at the both sides of the push plate 104 rotatably and abutted to the respective guide rails 112 .

The guide rollers 114 are supported on rotation shafts 116 which are installed at both sides of the push plate 104 in the upright direction.

The operation of the conventional media cassette for an automatic dispenser will be described as follows.

If the handle 110 formed in the push plate 104 is pulled to the rear, the push plate 104 moves rearwardly overcoming the elastic force of the spring 106 . After moving the push plate 104 , media are received to the inside of the cassette body 102 sequentially with the push plate 104 being held back manually to prevent the push plate 104 from moving forwardly.

In case the handle 110 of the push plate 104 is released after completing loading of the media, the push plate 104 moves forwardly by the elastic force of the spring 106 and the media between the cassette body 102 and the push plate 104 is pressed by a certain elastic force. Once the loading is completed, the media cassette is ready to be installed and used for the automatic dispenser.

However, the conventional media cassette for the automatic dispenser has problems that the operation is difficult, the operation time is long and inferior results are produced in case of installing it in the automatic dispenser due to the irregular reception of the media after the operation since a user must move the support plate rearwardly and hold it so that it with one hand cannot move forwardly while holding the media into the cassette body with the other hand.

To solve the above problem, a locking tool is installed between the support plate and the cassette body, the push plate is pulled backed and locked, media is loaded, and when a locking release button is pushed, locking of the push plate is released thus to support the media.

However, in the above conventional media cassette, locking of the push plate must be released before loading the media cassette into the automatic dispenser. In case the user loads the media cassette into the automatic dispenser without pushing the locking release button by mistake, there occurs a problem that the media are not supplied to the dispenser because the push plate is held in the locked state.

Also, since the conventional media cassette can store only one kind of media, media of different sizes can not be stored thus to limit the usage of the cassette.

SUMMARY OF THE INVENTION

Therefore, an object of the present invention is to provide a media cassette for an automatic dispenser which can be used easily and which solves the problems of incorrect operation in case of loading a cassette with a locked push plate since locking of the push plate is automatically released if the automatic dispenser receives the cassette with a locked push plate.

The media cassette for an automatic dispenser includes a cassette body 2 having a certain interior space in which media to be dispensed is received, a push plate 4 installed slidably in the cassette body 2 for supporting media received therein, an elastic member 6 positioned between the push plate 4 and the cassette body 2 for urging the push plate towards a dispensing position of the media, guide members installed between the both side surfaces of the push plate 4 and the inner sides of the cassette body 2 for guiding the push plate 4 to perform linear movement, and a locking mechanism installed between the push plate 4 and the cassette body 2 for locking the push plate 4 .

In the cassette body 2 , a width varying device which can vary the width of the interior space in the cassette body 2 according to the size of the media is installed.

The cassette body 2 has a rectangular shape. At a front lower side of the cassette body, an outlet port 8 for discharging stored media is formed and a guide line 10 which guides the media in case of receiving the media into the automatic dispenser is formed at both side surfaces.

The push plate 4 is installed in the cassette body 2 standing upright and having a shape of a flat plate and has a handle 12 with which a user can hold and pull at the center of the upper side of the push plate.

The elastic member 6 has an end fixed on the rear surface of the push plate 4 and another end having a coil spring fixed on the inner wall surface of the cassette body 2 for pushing the push plate 4 .

As shown in FIG. 5 , the guide members include a guide rods 14 which are installed at the both sides of the cassette body extending in the longitudinal direction and guide holes 16 formed at the both sides of the push plate 4 and respectively fixed slidably on the guide rods 14 .

Here, in each of the guide holes 16 , a bushing 18 is inserted thus to help the guide holes slide on the guide rods 14 .

The locking mechanism includes a hook assembly 22 mounted through an installing hole 20 which is formed in the center of the rear side wall of the cassette body 2 for locking the push plate 4 and a latching pin 24 provided at the center of the rear side of the push plate 4 and engageable by the hook assembly 22 .

The hook assembly 22 includes a bracket 28 which is mounted in the installing hole 20 as formed in the cassette body 2 with bolts 26 , a hinge shaft 30 transversely fixed to the bracket 28 , a hook member 36 having an end protruded to the inner side of the cassette body 2 forming a hook part 32 which is protruded outwardly from the cassette body 2 and engageable with the latching pin 24 and another end having a locking release button part 34 for releasing locking operation under the condition of being rotated on the hinge shaft 30 and a return spring 38 for urging the hook member 36 to its original position on the hinge shaft 30 .

Here, the locking release button part 34 of the hook member is formed to be protruded outwardly of the cassette body 2 at a certain angle so that the button can be pushed and operated when a door of the automatic dispenser is closed.

The latching pin 24 is fixed to two mounting parts which are protruded at a certain interval from the rear surface of the cassette body 2 , and retaining ring 50 for preventing separation of the latching pin 24 are installed at both ends of the latching pin 24 .

The locking mechanism overcomes the elastic force of the elastic member 6 and the push plate 4 moves inwardly in the cassette body 2 in case of holding and pulling the handle 12 of the push plate. At this time, the latching pin 24 is latched by the hook part 32 of the hook member and the push plate 4 is locked. In this condition, if the door (not shown) of the automatic dispenser is closed after the media are stored in the cassette body 2 , the rear surface of the door pushes the locking release button part 34 , whereby the hook member rotates out of latching engagement with the latching pin and thereby locking of the push plate 4 is released and the push plate 4 supports the media with certain elastic force.

As shown in FIG. 5 , the width varying device includes a support panel 52 installed at each side of the cassette body 2 extending in the longitudinal direction for respectively supporting both side surfaces of the media, first, second and third position determining holes 54 , 56 and 58 which are formed in the bottom surface at both sides of the cassette body 2 at certain intervals so that the position of the support panels 52 in the transverse direction in the cassette body 2 can be changed according to the size of the media stored and position fixing bolts 60 for fixing the support panels 52 to the position determining holes 54 , 56 and 58 .

The number of the position determining holes 54 , 56 and 58 can be increased accordingly as the size of the media varies.

Each supporting panel 52 has a bolt hole 62 where a position fixing bolt 60 is installed on the surface abutted on the bottom surface of the cassette body 2 .

The width varying device fixes the supporting panels 52 by selecting one of the first, second and third position determining holes 54 , 56 and 58 according to the size of the stored media.

Operation of the media cassette for the automatic dispenser in accordance with the present invention with the above composition will be described.

FIG. 6 is a block diagram showing the media cassette in accordance with the present invention.

Firstly, in case of holding and pulling back the handle 12 of the push plate to secure a space for storing the media, the push plate 4 overcomes the elastic force of the elastic member 6 and moves inwardly in the cassette body 2 . At this time, the push plate 4 performs linear movement along through the guide rods 14 since the guide holes 16 of the push plate 4 move along the guide rods 14 of the cassette body 2 .

If the push plate 4 moves to near the rear portion of the cassette body 2 , the latching pin 24 which is installed on the push plate 4 is latched on the hook assembly 22 installed at the rear of the cassette body 2 and the push plate 4 is locked.

In this condition, after storing the media in the cassette body 2 , the media cassette is ready to be received into the automatic dispenser. Here, if the door of the automatic dispenser is closed after receiving the media cassette into the automatic dispenser, the rear surface of the door pushes the locking release button part 34 of the hook assembly and accordingly, the locking of the push plate is related and the media is supported elastically toward the dispensing end due to releasing of the locking of the push plate 4 .

Namely, if the rear surface of the door pushes the locking release button part 34 , the hook member 36 rotates around the hinge shaft 30 , whereby the hook part 32 is separated from the latching pin 24 and locking is released.

In case of storing a media having a bigger size than that of the currently stored media, the position fixing bolts 60 are tightened after moving the supporting panels 52 to the direction of the inside of the cassette body and aligning the bolt holes 62 with the third position determining hole 58 . On the contrary, in case of storing a media having a smaller size than that of the currently stored media, the position fixing bolt 60 is tightened after moving the supporting panel 52 to the direction of the inside of the cassette body and aligning the bolt holes 62 with the first position determining hole 54 .

The media cassette in accordance with the present invention with the above composition and operation can prevent a incorrect operation generated in case of receiving the cassette with a push plate of which locking is not released by releasing locking of the push plate by having the door push the locking release button if the media cassette is received and the door is closed after storing the media by locking the push plate with the locking mechanism and the present invention has an advantage that its use is convenient since locking of the push plate does not need to be released by hand.

Also, the media cassette in accordance with the present invention has another advantage that its usefulness can be widened since media of many difference side edges can be received by having the supporting panels for supporting the both sizes of the media movable at the both sides of the cassette body in the transverse direction.

As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalence of such meets and bounds are therefore intended to be embraced by the appended claims.
