BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a media dispenser, and more particularly, to a media dispensing apparatus for allowing a medium to be normally discharged or withdrawn from the inside of a media dispenser.

The automatic dispenser is capable of paying or storing media such as cash, checks, slips, receipts, and various kinds of paper. An example of such a media dispenser is an automated-teller machine. Financial automation equipment is a device that allows customers to deposit or withdraw cash or checks directly without going through the bank window. Such a financial automation device is widely used in order to improve the efficiency of the banking business and the convenience of the customer.

1 is a configuration diagram showing a media branching device of a conventional media dispenser. As shown, the media branching device is provided with a drive motor 2 that provides power for transporting the media. A driving gear 4 is provided on the rotating shaft 2 'of the driving motor 2 to receive power from the driving motor 2 and rotate.

A coupling gear (6) is engaged with the driving gear (4). The connecting gear 6 is provided so as to engage with a gear portion (not shown) of the conveying roller 8. Accordingly, the conveying roller 8 receives the power from the driving motor 2 and rotates to transfer the medium in the direction of the arrow. The pair of conveying rollers 8 are installed in close contact with each other to convey the medium by frictional force. The conveying rollers 8 may be installed along the conveying path of the medium.

On the other hand, the medium conveyed by the conveying roller 8 is determined by the conveying path in the diverter 16 to be described below. A solenoid (10) is provided as a driving source of the diverter (16). The solenoid 10 is a driving source driven according to an on-off signal. A plunger (12) is installed on the solenoid (10) so as to be movable in and out of the solenoid (10). The plunger 12 is moved in accordance with an on / off signal of the solenoid 10 and is protruded to the outside. When a signal is applied to the solenoid 10, the plunger 12 is inserted into the solenoid 10 by an electromagnetic force. do.

A plunger shaft 12 'is provided at a front end of the plunger 12 and a wire 14 is connected to the plunger shaft 12'. The wire 14 is connected to the diverter shaft 16 'of the diverter 16. The wire 14 is connected at both ends to the plunger shaft 12 'and the diverter shaft 16' to transmit the power of the solenoid 10 to the diverter 16.

The diverter 16 serves to determine the path through which the medium is transported, and can be transported separately from a normal medium and an abnormal medium (such as a damaged medium). The diverter 16 receives power from the solenoid 10 and rotates in the direction of the arrow shown in Fig. On the other hand, a sensor 18 is installed at the passing point of the diverter 16. The sensor 18 senses whether the medium has been normally transported by the diverter 16.

However, the above-described conventional techniques have the following problems.

In the prior art, two drive sources are used to branch the medium at the diverter 16. A drive motor 2 for transporting the medium and a solenoid 10 for rotating the diverter 16 are used respectively. If the medium is transported and branched by using two driving sources as described above, there is a burden that the control of each driving source must be more precise. That is, if the control is not accurately performed by the diverter 16 in accordance with the feeding speed of the medium, jamming of the medium occurs in the diverter 16.

Further, by using two driving sources, there is a problem that the number of parts to be incorporated into the product increases, and the component ratio increases.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to control the transfer and the branching of the medium with one drive source.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a media branching apparatus for a media dispenser according to the present invention will be described in detail with reference to the accompanying drawings.

The inside of the media dispenser is provided with a customer access unit for recovering a normal medium requested by the customer and a recovery unit for recovering abnormal media due to damage or the like. The transfer path of the medium, which is divided into the customer access unit and the recovery unit, is provided with a diverter so that the medium can be transferred to the customer access unit or the recovery unit. That is, the diverter determines the path through which the medium is transported.

2 is a configuration diagram showing a media branching device of a media dispenser according to the present invention.

As shown, the media branching device is provided with a drive motor 20 that provides the power necessary for transport and branching of the media. The drive shaft 20 'of the drive motor 20 is provided with a diverter 22. The diverter 22 receives power from the driving motor 20 and rotates to determine the path of the medium. The diverter 22 is preferably not completely fixed to the drive shaft 20 'in the present embodiment but may be coupled to the drive shaft 20' through a frictional material such as rubber. This is because when the diverter 22 receives power from the drive motor 20 as it is, a load may be applied to the diverter 22.

The diverter 22 may be installed not only to be directly coupled to the drive shaft 20 'but also to receive power by a separate pulley wound on the drive shaft 20'. The diverter 22 is rotated at a fine angle clockwise or counterclockwise by the drive motor 20 to determine the path through which the medium is transported. That is, when the diverter 22 is rotated in the clockwise direction in Fig. 2, the medium is transported in the right direction, and when the diverter 22 is rotated in the counterclockwise direction, the medium is transported in the left direction.

On the other hand, a magnet 23 is provided at a portion adjacent to the tip of the diverter 22. The magnet 23 applies a magnetic force to the diverter 22 when the diverter 22 is rotated to determine the path of the medium so that the diverter 22 can be fixed by gravity. One of the magnets 23 is opposed to the other, and one of the magnets 23 is positioned to the customer access portion and the other to the collecting portion. Since the diverter 22 receives a magnetic force from the magnet 23, the diverter 22 is made of a steel material that can be attracted to magnetic force. Of course, the die butter 22 may be made of steel material so that its distal end portion is made to receive magnetism.

A drive gear 24 is coupled to the drive shaft 20 '. The driving gear 24 is a portion rotated together with the driving shaft 20 'by the power of the driving motor 20.

The drive gear 24 meshes with the one-way gears 26 and 28, respectively. The one-way gears 26 and 28 are constituted by a first one-way gear 26 and a second one-way gear 28 and are rotatably supported by the first and second gear shafts 26 'and 28' Respectively. The one-way gears 26 and 28 are coupled to the gear shafts 26 'and 28' by a one-way bearing.

In the present embodiment, the one-way bearing is engaged so that the one-way gears 26 and 28 are rotated only in the arrow directions a and b shown in FIG. 2 with respect to the gear shafts 26 'and 28'. This will be described as a one-way direction. Therefore, when the one-way gears 26 and 28 are rotated in the directions opposite to the arrow directions a and b, the one-way gears 26 and 28 are restrained by the gear shafts 26 'and 28' (26 ', 28'). That is, the one-way gears 26 and 28 are provided so as to be rotatable in the one-way direction opposite to each other.

As described above, the power transmitted from the drive motor 20 is transmitted by the one-way gears 26 and 28 so that the power by the drive motor 20 is transmitted to the feed rollers 40 and 42 So that both the feeding and branching of the medium can be performed by one driving motor 20. [ This will be described in more detail in the following power transmission process.

On the other hand, the gear shafts 26 'and 28' may be provided with transfer rollers (not shown) for transferring the media, respectively, so as to transfer the media diverted by the divertor 22.

The power transmitted to the one-way gears 26 and 28 is transmitted to the first and second connection pulleys 30 and 32. The connecting pulleys 30 and 32 are provided with first and second connecting shafts 30 and 32 and the belt B is wound on the pulleys provided on the connecting shafts 30 'and 32' . Accordingly, the connection pulleys 30 and 32 receive the power from the one-way gears 26 and 28 and rotate. In this embodiment, the two connection pulleys 30 and 32 are shown connected to each other by a belt B, but this is shown for convenience of illustration, and the connection pulleys 30 and 32 may be formed as a single unit It is possible.

The belt B wound on the connection pulleys 30 and 32 is wound on a pulley provided on the first and second feed roller shafts 40 'and 42'. Accordingly, the power transmitted to the connection pulleys 30 and 32 is transmitted to the first and second feed rollers 40 and 42, respectively. The feed rollers 40 and 42 serve to feed the medium to the die butter 22 side.

The pair of feed rollers 40 and 42 are installed in close contact with each other and rotated. Here, the feed rollers 40 and 42 are controlled to rotate only by the drive motor 20. That is, when the feed roller 40 receives power directly from the drive motor 20 and rotates, the feed roller 42 is rotated together with the feed roller 40 by a frictional force to transfer the medium. The feed rollers 40 and 42 may be provided on the feed path of the medium.

Next, the configuration of another embodiment of the present invention will be described with reference to FIG. 3, detailed description of the same configuration as the above-described embodiment will be omitted.

The drive gear 124 of the drive motor 120 used as a power source in this embodiment is engaged with the first one-way gear 126 and the second one-way gear 128. The first one-way gear 126 and the second one-way gear 128 are installed on the first and second gear shafts 126 'and 128', respectively, so as to rotate in opposite directions as in the above-described embodiment. That is, the one-way gears 126 and 128 are installed to be rotated in the directions of arrows a and b shown in FIG.

An interlocking pulley 130 is provided on the gear shaft 128 'of the second one-way gear 128. The interlocking pulley 130 is connected by a belt B to a feed pulley 138, which will be described below. That is, the belt B is wound around the interlocking pulley 130 and the feed pulley 138 to transmit power.

Next, the belt B is wound on the pulley provided on the gear shaft 126 ', and the belt B is wound on the pulley provided on the first connecting shaft 132'. The first connecting gear 132 is engaged with the second connecting gear 134. Here, it is preferable that the connecting gears 132 and 134 are formed of two pieces. This is because the first one-way gear 126 and the first gear shaft 126 'can be rotated in the idle state in opposite directions to each other when the rotational direction is changed once in the course of passing through the connecting gears 132 and 134 . That is, the first and second connection gears 132 and 134 serve to switch the rotation direction in which the power is transmitted to the opposite direction.

The belt B is wound on the pulley provided on the second connection shaft 134 'of the second connection gear 134 and the belt B is wound on the feed roller shaft 136' So that the power is transmitted. The feed roller 136 serves to feed the medium toward the die butter 122. A plurality of feed rollers 136 may be installed on the transport path of the medium.

An idler roller 140 is installed at a position corresponding to the feed roller 136, respectively. The idle roller 140 is installed in an idle state in close contact with the feed roller 136. The idle roller 140 cooperates with the feed roller 136 to transport the medium in frictional force. Although not specifically shown in the drawing, the idle roller 140 is brought into close contact with the feed roller 136 by the elastic force of the spring.

Hereinafter, the operation of the media branching device of the media dispenser according to the present invention will be described in detail.

Referring to FIG. 4, a process of delivering power according to a preferred embodiment of the present invention will be described.

When the drive motor 20 is rotated in the direction of the arrow shown in the drawing, the first one-way gear 26 is rotated in the idle state by the one-way bearing. That is, the first gear shaft 26 'is fixed and only the first one-way gear 26 rotates. The second one-way gear 28 rotates in a direction opposite to the one-way direction and rotates together with the second gear shaft 28 '.

The first and second one-way gears 26 and 28 are rotated in the same direction. However, only the second gear shaft 28 'is rotated by the second one-way gear 28 and the second one- And is rotated together. As the second gear shaft 28 'is rotated, the second connection pulley 32 is rotated in conjunction therewith. The power transmitted to the second connection pulley 32 is transmitted to the second feed roller 42 through the belt B. Accordingly, the second feed roller 42 rotates in the feeding direction of the medium, and contacts the one side of the medium to feed the medium by frictional force.

Next, when the second feed roller 42 is rotated, the first feed roller 40, which was in close contact with the second feed roller 42, also rotates together. When the first feed roller 40 is rotated, the first feed roller shaft 40 'is rotated together with the first feed roller shaft 40'. Also, the power transmitted to the first connecting pulley 30 rotates the first gear shaft 26 '. Since the first one-way gear 26 is rotated in the idle state by the one-way bearing, the first one-way gear 26 can be normally driven even if it is rotated in the opposite direction to the first gear shaft 26 '. Meanwhile, when the drive motor 20 is driven in the opposite direction, power can be transmitted through the first one-way gear 26 and the first gear shaft 26 '.

As described above, in the present invention, the first and second one-way gears 26 and 28 are provided to drive the diverter 22 and the first and second feed rollers 40 and 42 by one drive motor 20 The first and second one-way gears 26 and 28 and the first and second gear shafts 26 'and 28' are idled in the process of transmitting power through the first and second feed rollers 40 and 42 It can be driven without difficulty. If the first and second one-way gears 26 and 28 are fixed to the first and second gear shafts 26 'and 28', such power transmission will not be possible.

On the other hand, when the driving shaft 20 'is rotated by the driving motor 20, the diverter 22 is rotated in conjunction with the rotation of the driving shaft 20', and the diverter 22 transports the medium in the left direction in the drawing. For example, if it is detected that the medium is normal, the medium may be diverted to the left direction and transferred to the customer access side.

Next, a process of delivering power according to another embodiment of the present invention will be described with reference to FIG.

The first one-way gear 126 is rotated in the idle state with respect to the first gear shaft 126 'and the second one-way gear 128 is rotated in the idle state when the drive motor 120 is driven in the direction of the arrow in the figure, Is rotated together with the second gear shaft 128 '.

The power transmitted to the second one-way gear 128 is transmitted to the feed pulley 138 through the interlocking pulley 130. The feed pulley 138 is rotated together with the feed roller shaft 136 ', and the feed roller 136 is rotated in conjunction therewith so that the medium can be transported. At this time, the idle roller 140 is brought into close contact with the feed roller 136 to feed the medium by frictional force. That is, the present embodiment differs from the above-described embodiment in that the medium is transported through the idle roller 140. [

When the feed roller 136 is rotated, the first and second connecting gears 132 and 134 are rotated, and the first gear shaft 126 'is rotated in a direction opposite to the first one- . At this time, since the first one-way gear 126 is rotated in the idle state, the first one-way gear 126 can be driven without difficulty.

Meanwhile, when the drive shaft 120 'is rotated by the drive motor 120, the diverter 122 is rotated in conjunction with the rotation of the drive shaft 120', and the diverter 122 transports the medium to the left in the drawing. For example, if it is detected that the medium is normal, the medium may be diverted to the left direction and transferred to the customer access side.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.
