[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device for a vending machine, and more particularly, to a vending machine of a cup bender type in which powder such as coffee powder is dissolved in hot and cold water and poured into a paper cup for sale. The present invention relates to a liquid crystal display device for a vending machine suitably used for a vending machine.

[0002]

2. Description of the Related Art Vending machines are installed indoors and outdoors to sell various products. Among them, inside a vending machine, powder such as coffee powder and hot water are separated. When the user presses a button or the like to select a favorite beverage, the powder is appropriately combined and dissolved in hot water or water, and taken out when the user presses the button or the like. 2. Description of the Related Art A vending machine that pours it into a paper cup set in a mouth and sells the vending machine is well known. Such a vending machine is called a “cup bender type”.

One of the features of such a vending machine of the cup bender type is that the amount of coffee, sugar, cream and the like can be increased or decreased. That is, many vending machines of the cup bender type are provided with buttons that can arbitrarily adjust these amounts.

In recent years, there have been vending machines provided with a liquid crystal display on the front in order to advertise to a person passing in front of the vending machine to attract the attention of the person and increase their willingness to purchase. . That is, the liquid crystal display provided on the front side outputs video / audio data recorded on a built-in CD-ROM or the like.

A liquid crystal display device provided in such a vending machine will be described. As shown in FIG. 4, the liquid crystal display device 9 has a liquid crystal display on the front side (omitted in FIG. 4) and the recording medium reproducing device 2 on the back side. The liquid crystal display on the front side is attached to the vending machine so as to be exposed from the front of the vending machine, and displays information on the recording medium reproduced by the recording medium reproducing device 2 provided on the rear side. .

This is applied to a cup vender type vending machine. For example, when there is no user, image / audio data is output, and when there is a user, the amount of sugar or the like adjusted on a liquid crystal display is output. For example, switching of an image to be output in conjunction with a human sensor or the like has been considered. Of course, it is also considered that a touch panel is provided on the front surface of the liquid crystal display so that the user can adjust the amount of sugar or the like by pressing the liquid crystal display.

[0007]

However, as described above, powdery raw materials such as coffee powder are stored in the cup vending machine type vending machine. The raw material is discharged from the storage in a designated amount, and a certain amount of powder of the raw material is scattered in the vending machine at every sales operation. In addition, when these powder materials are insufficient, the vending machine is opened and replenished as appropriate, but the powder may scatter at the time of replenishment.
When the vending machine is closed with the scattered powder as it is, the powder enters the recording medium reproducing device interior 2 by convection of air inside the vending machine by a fan or the like provided for cooling the vending machine. Then, there is a problem that the recording medium adheres to a head for reading the recording medium. Naturally, the powder adhering to the head hinders reading of the recording medium, and the video / audio etc. may be intermittent or in the worst case,
The recording medium reproducing device 2 breaks down.

[0008] Of course, it is only necessary to remove the scattered powder each time. However, the powder often scatters directly into places that cannot be reached by humans. Is not easy to remove.

[0009] In particular, the recording medium reproducing apparatus 2 uses a CD-RO
Since a motor for driving a recording medium such as M is provided, heat generated from this motor must be released.
Therefore, a cooling fan 4 is usually provided in the recording medium reproducing device. However, a liquid crystal display device for a vending machine incorporating the recording medium reproducing device 2 provided with the cooling fan 4 is changed to a cup vender type vending machine. When provided, the cooling fan not only promotes the convection of the powder such as coffee powder inside the vending machine, but also collects the powder in the recording medium reproducing device 2, so that the powder can enter the recording medium reproducing device 2. There is also the problem of contributing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 shows a liquid crystal display device 1 for a vending machine according to the present invention (hereinafter simply referred to as a “liquid crystal display device”).
FIG. As shown in FIG. 1, a recording medium reproducing device 2 is provided on the back side of a liquid crystal display device 1 according to the present invention. Further, as shown in FIG. 3, a liquid crystal display 8 is provided on the front side of the liquid crystal display device 1 according to the present invention.

As shown in FIG. 1, a tray 21 for storing a recording medium (not shown), such as a CD-ROM, is provided in the recording medium reproducing apparatus 2 through a reproducing apparatus opening 22 through the liquid crystal display apparatus 1. It is designed to be put in and out on the back side of. That is, when the recording medium is replaced, the tray 21 is pulled out to the rear side from the playback device opening 22, and when the recording medium is set in the recording medium
1, the recording medium is placed, and then the tray 21 is inserted into the recording medium reproducing device 2 through the reproducing device opening 22. The recording medium reproducing device 2 has a built-in head (not shown) also called a “pickup” for reading information written on the recording medium and a motor (not shown) for rotating the recording medium. I have.

In FIG. 1, most of the recording medium reproducing device 2 including the head and the motor is built in the liquid crystal display device, but one end surface of the tray 21 is exposed outside the liquid crystal display device. Therefore, FIG.
, When the tray 21 is inserted into the recording medium reproducing device 2, one end surface of the tray 21 is
Is to be closed. Of course, the playback device opening 2
A cover (not shown) is provided on one side in the longitudinal direction of the tray 2 so that the cover can be opened when the tray 21 is pulled out.
May be configured so that the lid closes the opening 22 of the playback device.

When the liquid crystal display device 1 shown in FIG. 1 is incorporated in a vending machine of the cup bender type, powder such as coffee powder convection inside the vending machine of the cup bender type is applied to one end face of the tray 21. It enters from between the periphery and the opening 22 of the reproducing apparatus, and adheres to a head provided inside the recording medium reproducing apparatus 2.

In order to prevent this, in the present invention,
As shown in FIG. 1, on the back of the liquid crystal display device 1,
The dustproof filter 3 is fixed so as to cover the back surface of the liquid crystal display device 1. More specifically, female screws 29 are embedded in the four corners on the back surface of the liquid crystal display device 1, and cut-outs 39 are provided in the four corners corresponding to the female screws 29 in the filter base 31 constituting the dustproof filter 3. By inserting four male screws (not shown) through the notches 39 and screwing into the female screws 29, the dustproof filter 3 is fixed to the back of the liquid crystal display device 1 as shown in FIG. Have been.

As described above, in the present invention, since the dustproof filter 3 covers the back surface of the liquid crystal display device 1, powder such as coffee powder, dust in the air, and smoke of tobacco invading from outside the vending machine. (Including fine powder)
Is cut by the dustproof filter 3, and clean air is taken into the dustproof filter 3. Therefore, since the amount of the powder entering the recording medium reproducing device 2 can be greatly reduced, the powder hardly adheres to the head provided inside the recording medium reproducing device 2.

In the present invention, it is sufficient that clean air is sent between the periphery of one end of the tray 21 into which powder such as coffee powder can enter and the opening 22 of the regenerating apparatus. Should cover at least this period. However, in practice, as mentioned above,
The recording medium reproducing apparatus 2 is usually provided with a cooling fan 4 for cooling a built-in motor (not shown) and the like so as to be stacked. As shown in FIG. 1, also in the present invention, a cooling fan 4 for sucking outside air to cool the recording medium reproducing device 2 is provided on the back surface of the liquid crystal display device 1.

Although such a cooling fan 4 promotes convection of powder and the like inside the vending machine, in the present invention, the cooling fan 4 is also covered with the dustproof filter 3 as shown in FIG. Is preferred. As a result, powder such as coffee powder collected in the recording medium reproducing device 2 by the cooling fan 4 can be cut, and since the cooling fan 4 always sucks clean air, recording is performed with powder, dust, and the like. An adverse effect on the liquid crystal display device 1 including the medium reproducing device 2 can be reduced.

In general, a vent 5 is often provided on the back surface of the liquid crystal display device 1, as shown in FIG. That is, the vent 5 is often provided for ventilation in which air heated by the heat accumulated inside is discharged to the outside, air is sucked in from the outside, and this is repeated.
It is preferable that such a vent 5 is also covered with the dustproof filter 3. Thereby, since the inside of the liquid crystal display device 1 can be always ventilated with clean air through the ventilation port 5, the possibility that the liquid crystal display device 1 is broken by dust, powder, or the like can be reduced.

In the present invention, as shown in FIG. 3, in order to make it more difficult for powder to enter between the periphery of one end surface of the tray 21 and the reproducing device opening 22, the reproducing device opening 22 shown in FIG.
Dust proof Hisashi 2 along one side or circumference and almost parallel to the back
4 is preferably provided.

Since the vending machine is provided with various devices in addition to the liquid crystal display device 1, it is desired to reduce the size of the liquid crystal display device 1 as much as possible. Here, in order to incorporate the recording medium reproducing device 2 in which the tray 21 is inserted and removed from the reproducing device opening 22 into the liquid crystal display device 1, for example, the tray 21 is moved from the side surface 18 of the liquid crystal display device 1 to the reproducing device opening portion. In a case where the tray 21 is taken in and out, the tray 21 protrudes from the liquid crystal display device 1 when the tray 21 is pulled out, and the liquid crystal display device 1 becomes large as a whole. In addition, for example, when the entire recording medium reproducing device 2 is made to protrude from the back surface of the liquid crystal display device 1, when the tray 21 is pulled out, the tray 21 protrudes from the outer frame 19 of the liquid crystal display device 1. Disappears, but the liquid crystal display device 1
Since the entire recording medium reproducing device 2 protrudes from the back of
Again, the size of the liquid crystal display device 1 is increased as a whole.

Therefore, in the present invention, as shown in FIG. 1, the tray 21 moves obliquely (in the direction of the arrow in FIG. 1) with respect to the back surface of the liquid crystal display device 1 so that the back surface of the liquid crystal display device 1 can be moved. It is preferable that the recording medium reproducing device 2 provided on the side be taken in and out, and that the portion of the recording medium reproducing device 2 other than the reproducing device opening 22 be incorporated in the liquid crystal display device 1. In this case, it is preferable that the reproducing device opening 22 is also inclined obliquely with respect to the back surface of the liquid crystal display device 1.

As described above, when the tray 21 moves obliquely and is taken in and out of the recording medium reproducing apparatus 2, when the tray 21 is pulled out, the tray 21 protrudes from the outer frame 19 of the liquid crystal display device 1. In addition, since only the reproducing device opening 22 protrudes from the rear surface of the liquid crystal display device 1, the thickness of the liquid crystal display device 1 can be reduced, and therefore the size of the liquid crystal display device 1 can be reduced. it can. Thereby, the dustproof filter 3 provided on the back of the liquid crystal display device 1
Can also be reduced in thickness.

The dust filter 3 is a liquid crystal display device 1
As described above, in the present invention, since the tray 21 moves in an oblique direction and is taken in and out of the recording medium reproducing device 2, the reproducing device opening 22 is opened from the rear of the liquid crystal display device 1. It is desirable that they protrude. The filter base 31 suitable for this is the surrounding 3
11 is parallel to the rear surface of the liquid crystal display device so as to be in close contact with the rear surface. Then, from the periphery 311 toward the center, the raised portion 312 is raised so as to be substantially perpendicular to the back surface. As shown in FIG. 1, an opening 313 surrounded by a raised portion 312 is opened in the center of the filter base 31. The opening 313 is closed by the dust filter main body 35. In the present embodiment, the filter base 31 is formed integrally from a hard plastic, so that the periphery 311 and the protruding portion 312 are formed so as to be continuous. May be configured.

Since the filter base 31 has the above-mentioned raised portion 312, the reproducing device opening 22 and the cooling fan 4 projecting from the back of the liquid crystal display device 1.
Can be completely covered. In addition, if the distance between the cooling fan 4 and the dust-proof filter body 35 is set according to the cooling capacity required of the cooling fan 4 and the height of the raised portion 312 is appropriately changed in accordance with the distance, the seal is partially sealed. The cooling capacity of the cooling fan 4 provided in the space between the dustproof filter 3 and the liquid crystal display device 1 does not decrease.

The dustproof filter 3 is divided into a filter base 31 fixed to the rear surface of the liquid crystal display device and a dustproof filter main body 35 mounted on the filter base 31, so that the dustproof filter to which powder or the like adheres is provided. In order to remove the powder from the filter 3, it is only necessary to remove the dust-proof filter body 35 from the filter base 31 and attach a new dust-proof filter body 35 to the filter base 31, and this replacement work can be performed very easily and without much trouble. In addition, the powder can be easily removed from the dust filter 3.

The specific operation of replacing the dustproof filter main body 35 will be described. As shown in FIG.
The protrusion 312 has four slits 36 provided at four locations, while four projections 351 project from the periphery of the dustproof filter body 35 so as to correspond to the slits 36. When replacing the dust-proof filter body 35, firstly, the dust-proof filter body 35 to be replaced to which the powder or the like has adhered is slightly bent, and the engagement between each projection 351 and each slit 36 is released. The protrusions 351 are slightly bent, and the protrusions 351 are inserted into the slits 36 so as to be engaged with the slits 36. Needless to say, such a dustproof filter main body 35 has flexibility in a direction perpendicular to the surface.

Also, when replacing the recording medium set in the recording medium reproducing apparatus 2, the recording medium can be taken out by pulling out the tray 21 from the reproducing apparatus opening 22 after once removing the dustproof filter main body 35. In addition, there is no need to remove the entire dustproof filter 3 from the back of the liquid crystal display device 1. Therefore, the recording medium can be replaced while the filter base 31 is fixed to the back surface.

The tray 21 pulled out from the playback device opening 22 overlaps with the opening 313 of the filter base 31 or straddles the opening 313 so that the opening 31 is closed.
If it comes out from 3, the recording medium held by the hand does not need to be moved in the filter base 31, and the recording medium can be easily replaced without being conscious of the filter base 31.

As the filter used for the dust-proof filter main body 35, a wire mesh and a cloth can be cited. With such a filter, the recording medium reproducing device 2
The powder is selectively separated from air containing powder such as coffee powder that can enter the dust filter, and clean air is taken into the dust filter 3. Since the cloth is finer than the wire mesh, powder such as coffee powder adheres more reliably, and the powder and the like can be separated efficiently. Further, among the cloths, in order to make the powder adhere more efficiently, a non-woven cloth such as a non-woven fabric is preferable to a non-woven cloth such as a woven cloth.

As the non-woven fabric, felt, cotton and the like can be cited. From the viewpoint of smoothly moving air between the dustproof filter 3 and the outside and efficiently removing powder and dust contained in the air, cotton is used. It is preferable to use When woven cloth or felt is used, these may be attached and fixed around the dust-proof filter main body 35, but since cotton is fluffy as compared with woven cloth or felt, Just sticking cotton around the circumference is not enough. In particular, when the cooling fan 4 is covered with the dustproof filter 3, the filter is sucked into the dustproof filter 3 by the cooling fan 4, so that the filter is desirably fixed to the inner periphery of the dustproof filter main body 35. It is.

For this reason, in the present invention, as shown in FIG. 1, the dust-proof filter main body 35 is constituted by two parallel sheets 353 each having an opening 352 at a predetermined position and cotton interposed therebetween. Is preferred. In this case, the cotton is sandwiched between the two sheets and securely fixed, and the cooling fan 4 can be prevented from sucking the cotton.
Although the shape of the opening 352 provided in the sheet 353 is not particularly limited, in order to securely fix the cotton sandwiched therebetween and expose the cotton to the outside as much as possible to enhance the filtering ability, as shown in FIG. It is preferable that the rectangular openings 352 are arranged in a matrix so as to leave a partition in a lattice shape. Of course, a non-woven fabric other than cotton and a woven fabric may be interposed between the two parallel sheets 353. If necessary, the eyes may be made finer by stacking two or more wire meshes or cloths.

A cable (not shown) for supplying power or the like to the liquid crystal display device 1 often extends from the back of the liquid crystal display device 1. On the other hand, in the present embodiment, as shown in FIG. 1, the dustproof filter 3 is attached so as to cover the back surface of the liquid crystal display device 1. Therefore, as shown in FIG.
The dustproof filter 3 has a cable hole 3 separately from the opening 313.
Preferably, a cable 8 is provided through which a cable is passed. Such a cable hole 38 also has a role of bundling a plurality of cables.

In the above description, the filter base 3
The filter base 1 and the dustproof filter main body 35 may be separated from each other, but the filter base 31 and the dustproof filter main body 35 may be integrally formed. Needless to say, the liquid crystal display device for a vending machine according to the present invention is used by being incorporated in a vending machine such that the liquid crystal display 8 on the front side is exposed from the front.

In the above description, the recording medium is placed on the tray 21 which is inserted into and removed from the opening 22 of the reproducing apparatus, and is inserted into and removed from the recording medium reproducing apparatus 2. As described above, a swinging lid may be attached, and this lid may be opened and closed when the recording medium is replaced. In this case, since powder such as coffee powder intrudes from around the lid, the filter 3
The cover only needs to cover the periphery of the lid, and the dust-proof Hisashi is provided so as to cover the periphery of the lid.

In the above description, a so-called CD-ROM player has been described as an example of the recording medium recording device 2. However, the recording medium recording device 2 is not limited to this. For example, a DVD-RAM reproducing device, a DVD -ROM
The recording medium may be set by inserting a recording medium into a slit, such as a floppy disk drive, an optical disk drive, or an MD drive, and pushing up a lid covering the slit. Such a playback device may be used.

[0044]

As described above, according to the present invention, in the recording medium reproducing device 2, as in the reproducing device opening 22,
Since the dust filter 3 that covers the portion exposed to the rear surface is provided on the rear surface side, powder such as coffee powder can be prevented from entering the recording medium reproducing device 2. Thereby, the possibility that the recording medium reproducing device 2 breaks down due to powder convection inside the vending machine can be reduced.

Further, by providing a dust proof cover on at least a part of the portion exposed on the back surface, the powder convection inside the vending machine can be more effectively prevented from entering the inside of the recording medium reproducing device 2. it can.

If the recording medium is placed and the tray 21 is moved obliquely with respect to the rear surface of the liquid crystal display device and is taken in and out of the recording medium reproducing device 2, the size of the liquid crystal display device can be reduced. Can be.

In general, a cooling fan 4 for cooling the recording medium reproducing device 2 is attached, and powder such as coffee powder collects in the recording medium reproducing device 2. In such a case, the dustproof filter 3 is also used. By covering the cooling fan 4, it is possible to effectively prevent the powder from entering the inside of the recording medium reproducing device 2.

Similarly, even if a vent for ventilating the inside of the liquid crystal display device 1 is provided, if the vent hole is covered with the dustproof filter 3, powder enters the inside of the liquid crystal display device 1. Can be prevented.

The dust-proof filter 3 is separated into a filter base 31 fixed to the back of the liquid crystal display device 1 and a dust-proof filter body 35 mounted on the filter base, so that the dust-proof filter body 3 to which powder or the like adheres.
5 can be easily replaced.

When the dust-proof filter body 35 in which the cotton is sandwiched between the two parallel sheets 353 having the openings 352 is used, the powder and the like can be separated very efficiently by the cotton. Instead, cotton can be firmly fixed. In particular, even when the cooling fan 4 is provided inside the dustproof filter 3, fluffy cotton is not sucked into the cooling fan 4.

The structure in which the filter base 31 is raised from the periphery 311 toward the center allows the height of the raised portion 312 to be increased even when a part of the recording medium reproducing device 2 and the cooling fan 4 protrude from the back surface. By adjusting the height arbitrarily, the performance of the cooling fan 4 can be maintained.

Further, if the tray 21 pulled out from the opening 22 of the reproducing apparatus is overlapped with the opening 313 of the filter base 31 or is made to come out from the opening 313, the tray 21 can be easily operated without being conscious of the filter base 31. Can be replaced with another recording medium.

By providing a cable hole in the filter base separately from the opening 313, a cable for supplying power or the like to the liquid crystal display device 1 can be connected to the back surface. When a plurality of cables are connected, the cables can be bundled by the cable holes.

As described above, according to the present invention, the powder is prevented from entering the inside of the recording medium reproducing apparatus, so that the powder does not adhere to the head for reading the recording medium. Or, in the worst case, breakdown of the recording medium reproducing apparatus.

In particular, if the cooling fan 4 is incorporated and the dustproof filter main body 35 is made detachable from the filter base 31, the air inside the vending machine is collected by the cooling fan 4 and adheres to the dustproof filter main body 35. However, since the dust-proof filter main body 35 can be easily replaced, it is easy to remove the powder.

Therefore, according to the present invention, there is provided a liquid crystal display device for a vending machine for preventing powder such as coffee powder from entering a recording medium reproducing device, and a vending machine provided with the device.
