Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a beverage dispensing apparatus, and more particularly, to a different fluid for a main beverage, for example, a secondary beverage for adding a flavor or a beverage for pressurizing and mixing a gas such as air for foaming. Regarding the dispensing device.

2. Description of the Related Art Conventionally, there is a beverage dispensing apparatus that mixes and provides different types of beverages, in particular, a concentrated undiluted solution and a diluent. This beverage dispensing device, for example, is provided in a cup-type beverage vending machine and the like that dispenses and mixes different beverages into cups, and is used when selling many types of beverages. It is only necessary to supply a concentrated beverage having a smaller volume and weight to the beverage dispensing device than the diluted beverage, which is convenient for installation of the beverage dispensing device. In addition, such a beverage dispensing device can change the flavor of the beverage to be dispensed by changing the degree of dilution of the beverage, so that the flavor of the beverage to be dispensed is adjusted to the taste of the purchaser. It is convenient.
Various ideas have been devised for such a beverage dispensing apparatus that mixes different beverages (see Patent Literature 1 and Patent Literature 2).

On the other hand, in a sparkling beverage such as beer or low-malt beer, a beverage dispensing device that mixes a gas with the beverage, for example, a tap device of a beer server is used instead of mixing different beverages. . In sparkling beverages such as beer and low-malt beer, foam plays a role in preventing the desorption of carbon dioxide dissolved in the beverage and a role in preventing oxidation, and also has a tongue when the beverage is contained in the mouth. It is also important from the viewpoint of improving the taste. In effervescent beverages such as beer, in general, the smaller the foam diameter, the more uniform the foam, the smoother the mouthfeel, and the longer the retention time of the foam. It is preferred.
For this reason, mainly in sparkling beverages such as beer and low-malt beer, various types of tapping devices that apply foam to cover the liquid surface of the beverage with a foam layer are used so that fine bubbles can be easily poured out. (See Patent Document 3).

  Patent Document 1 discloses a beverage supply device that provides drinking water by mixing two or more different stock solutions for drinking water and a diluting solution for diluting the stock solution into a beverage container. . Valves are respectively provided in the supply paths of the undiluted solution and the diluent for drinking water, and the valves are operated by operating a switch corresponding to a predetermined combination of beverages. Are opened only for a predetermined time.

  In addition, Patent Document 2 discloses a beverage dispensing apparatus capable of dispensing a mixed beverage having a substantially constant concentration with a small and simple structure. This beverage dispensing apparatus dispenses a mixed beverage generated by supplying and mixing a plurality of beverages from a liquid raising pipe by pressurizing a plurality of beverage containers with an electric pump. The mixing ratio of the beverage is determined by the diameter of the pumping tube that is loosely inserted into the plurality of beverage containers.

Patent Document 3 discloses a tap device of a beverage dispenser that supplies foam gas by supplying an external gas to a flow path of beer and releasing the pressure of the beverage pressurized by flow path resistance.
The tap device of the beverage dispenser has a foam outlet and a liquid outlet, and can be switched between a liquid discharging mode and a foaming mode by using a mode switching mechanism including a switching lever and a flow path switching unit.

A beverage supply source 14 that supplies a beverage (hereinafter, also referred to as a main beverage) 32a to be occupied or a main component to a tap device 12 at a predetermined pressure (hereinafter, also referred to as a first pressure), and a secondary portion of a mixed beverage. And a sub-beverage supply source 15 that supplies a beverage (hereinafter, also referred to as a sub-beverage) 32b occupying or serving as a sub-component to the tap device 12 at a predetermined pressure (hereinafter, also referred to as a second pressure). 14 and the tap device 12 are connected by a supply pipe 18c communicating between them, and the auxiliary beverage supply source 15 and the tap device 12 are connected by a supply pipe 18b communicating between the two. Here, the beverage container 20 is disposed immediately below the tap device 12. In the present invention, the main beverage 32a refers to a beverage containing 50% or more of the mixed beverage, and the sub-beverage 32b refers to a beverage containing 50% or less of the mixed beverage. .

The beverage supply source 14 of the beverage dispensing device 10 stores a main beverage 32a such as a non-effervescent beverage such as coffee, milk, syrup, tea and juice, and a sweetened carbonated beverage such as cider and an effervescent beverage such as beer. And a gas supply source 16a for supplying a pressurized gas (a pressurized first gas) for pressurizing the liquid level of the main beverage 32a in the drink storage container 26a with a first pressure. The beverage storage container 26a and the gas supply source 16a are connected by a supply pipe 18d that communicates between the two.
The beverage storage container 26a of the beverage supply source 14 stores the main beverage 32a therein, and has an upper end connected to the supply pipe 18c and a lower end near the bottom of the beverage storage container 26a. It has a siphon tube 34a arranged in the main beverage 32a, and the upper end of the siphon tube 34a is liquid-tightly connected to the supply tube 18c connected to the tap device 12. Thus, the inside of the beverage storage container 26a of the beverage supply source 14 and the tap device 12 are communicated via the siphon pipe 34a and the supply pipe 18c.
The siphon pipe 34a of the beverage storage container 26a uses the principle of siphon to transfer the main beverage 32a near the bottom in the beverage storage container 26a pressurized by the pressurized first gas supplied from the gas supply source 16a to the beverage. This is for pulling up to the upper part of the storage container 26a and flowing to the supply pipe 18c connected to the upper end of the siphon pipe 34a.
In addition, in the beverage supply source 14, the supply pipe 18c connects the beverage storage container 26a and the tap device 12 in an airtight (hence liquid-tight) manner, and allows the pressurized beverage pushed out of the beverage storage container 26a to flow and the tap device 12 to flow. It is for supplying to.

The second valve portion 40c is located at the other end with respect to one end side where the rotating shaft 82 is located, and the first valve portion 40b is located closer to the rotating shaft 82 than the second valve portion 40c. 40a is located further on the rotation shaft 82 side than the first valve portion 40b. The second valve portion 40c includes a tapered portion 40d whose diameter is reduced toward the other end with respect to the rotating shaft 82 side, and a small cylindrical tip portion 40e which is connected to the tapered tip portion of the tapered portion 40d. A groove 86e is formed in the tapered portion 40d. In the illustrated example, the first valve portion 40b has an outer diameter slightly larger than the outer diameter of the shaft main body 40a. It is preferable that the second valve portion 40c is slightly smaller than the outer diameter of the first valve portion 40b.

  As shown in FIGS. 2 and 3, Y packings 70a, 70b, 70c, and 70d are respectively mounted on four grooves 86a, 86b, 86c, and 86d formed in the first valve portion 40b. I have. Each of the Y packings 70a to 70d is an annular sealing material made of an elastic material such as rubber, and has a shape in which an edge is branched into two portions in a direction orthogonal to a direction along an annular circumference. Have. The Y packings 70a and 70d are arranged such that the branch portions face the distal end portion 40e, and the Y packings 70b and 70c are arranged such that the branch portions face the rotation shaft 82 side. An O-ring 71 is mounted in a groove 88 formed in the tapered portion 40d of the second valve portion 40c.

Further, the shaft 40 extends from the opening provided on the outer peripheral surface (side surface) between the grooves 86b and 86c of the first valve portion 40b to the center of the shaft 40, and further from the center position to the second valve portion. A shaft-side sub-path 60 is formed so as to reach the center opening of the distal end 40e of the tip 40c. The shaft-side sub-path 60 communicates the opening on the outer peripheral surface between the grooves 86b and 86c and the center opening of the distal end portion 40e.
The rotation shaft 82 attached near the upper end of the shaft 40 is provided in a direction perpendicular to the longitudinal direction of the shaft 40, and serves as a center of rotation of a lever 38 described later when the shaft 40 is moved up and down. May be rotatably inserted into a rotating hole formed in the shaft 40, or may be fixed to the shaft 40 and rotatably inserted into a rotating hole provided in a lever 38 described later. It may be something.

  As shown in FIGS. 2 and 3, the shaft 40 of the tap device 12 is vertically movably inserted into the hole 42 of the device main body 36, but the flange 84 is formed when the shaft 40 is inserted into the hole 42. Then, the lower end of the coil spring 52 inserted into the upper portion of the shaft body 40a is supported, and is accommodated in the spring chamber 54 of the large diameter portion 50. Therefore, the outer diameter of the flange 84 is preferably slightly smaller than the inner diameter of the spring chamber 54 and larger than the inner diameter of the hole 42b of the valve body 44 so that the shaft 40 can move up and down.

  Here, the shaft 40 can be disposed on the apparatus main body 36 according to the following procedure. First, the large diameter portion 50 of the device main body 36 is removed from the valve body portion 44, and the shaft 40 is inserted into the hole 42 of the device main body 36. Then, the large-diameter portion 50 is screwed into the valve body portion 44 while the coil spring 52 is arranged so as to contact the flange 84 of the shaft 40 and the inward flange 50a of the large-diameter portion 50. When removing the shaft 40 from the apparatus main body 36, a procedure reverse to the procedure of disposing the shaft 40 on the apparatus main body 36 may be performed. As described above, the tap device 12 according to the first embodiment can easily separate the device main body 36 and the shaft 40, and thus has excellent maintainability.

Further, the first valve portion 40b of the shaft 40 is inserted into the hole 42b of the valve body portion 44 of the device main body 36 with the Y packings 70a to 70d mounted in the grooves 86a to 86d, respectively. The Y packings 70a to 70d are in close contact with the inner peripheral surface of the hole 42b of the valve body 44, respectively.
At this time, since the Y-packing 70a and the Y-packing 70b are arranged so that the respective branch portions face each other, the Y-packing 70a, the Y-packing 70b, the outer peripheral surface of the first valve portion 40b, and the valve body The gas and the liquid supplied to the space surrounded by the hole 42b of the portion 44 cannot flow out of this space through the place where the Y packings 70a and 70b are arranged. Further, since the Y packing 70a and the Y packing 70c are arranged so that their branch portions face each other, the Y packing 70a, the Y packing 70c, the outer peripheral surface of the first valve portion 40b, and the valve body portion 44 The gas and the liquid supplied to the space surrounded by the hole 42b, particularly, the space between the Y packing 70b and the Y packing 70c pass through the place where the Y packings 70a and 70c are arranged, and Can not be spilled to. Further, since the Y-packing 70d is disposed so that the branch portion thereof faces the seat 58 side of the valve body portion 44, the Y-packing 70d, the outer peripheral surface of the first valve portion 40b, and the The gas and liquid supplied to the space surrounded by the hole 42b cannot flow out of this space through the location where the Y packing 70d is disposed.

  The outer diameter of the first valve portion 40b of the shaft 40 is adjusted so that the Y packings 70a to 70d attached to the grooves 86a to 86d can be in close contact with the inner peripheral surface of the hole 42b of the valve body portion 44. It is preferable that the diameter of the hole 42b is slightly smaller than the inner diameter of the hole 42b. Further, by adjusting the depth of the grooves 86a to 86d, the contact state between the Y packings 70a to 70d and the inner peripheral surface of the hole 42b of the valve body portion 44 can be adjusted.

The second valve portion 40c of the shaft 40 is inserted up to the lower end of the hole 42b of the valve body portion 44 of the device main body 36 with the O-ring 71 attached to the groove 88 of the tapered portion 40d.
Here, the second valve portion 40c is disposed at a position where the distal end portion 40e faces the seat opening 58a of the seat portion 58 of the valve body portion 44 of the device main body 36. A main path 66 composed of a flow path 65 formed by a gap between the pipe 64 of the arm 46 and the outer peripheral surface of the second valve portion 40c and the inner peripheral surface of the hole 42b passes through the seat opening 58a. The end 40e is inserted into the central flow channel 68 of the nozzle 72, and the O-ring 71 is inserted into the groove 88 of the tapered portion 40d. It contacts the seat 58 of the portion 44 and moves between a position where the seat opening 58a is closed and blocked.
Note that the outer diameter of the distal end portion 40 e of the shaft 40 is smaller than the inner diameter of the central channel 68 of the nozzle 72.

  Here, the coil spring 52 is compressed most when the shaft 40 is pulled up and fixed at the open position by turning the lever 38 sideways. At this time, the opening of the main body side sub-path 56 formed on the inner peripheral surface of the hole 42b of the valve body portion 44, and the Y packing 70b mounted on the groove 86b and the Y packing 70c mounted on the groove 86c are formed. The openings of the shaft-side sub-path 60 located therebetween communicate with each other. As a result, the main body side sub-path 56 and the shaft side sub-path 60 communicate with each other, and both open the sub-path 62. At this time, the distal end portion 40e of the second valve portion 40c of the shaft 40 is disposed at a position facing the seat opening 58a of the seat portion 58 of the valve body portion 44 of the device main body 36, and the seat opening 58a is opened. The main path 66 including the pipe 64 and the flow path 65 communicates with the center flow path 68 of the nozzle 72.

Therefore, when the shaft 40 is in the open position, the main beverage 32a pressurized by the first gas flows down the main path 66 from the beverage supply source 14, passes through the seat opening 58a, and passes through the central flow path 68 of the nozzle 72. And the sub beverage 32b pressurized by the second gas flows down from the sub beverage supply source 15 through the sub path 62, and from the opening of the shaft side sub path 60 of the distal end 40e of the shaft 40, the apparatus main body 36 The main beverage 32a is supplied to the main beverage 32a flowing down the seat opening 58a, and in the central channel 68, the sub beverage 32b is mixed with the main beverage 32a to produce a mixed beverage.
Here, the position of the shaft 40 when the lever 38 is turned sideways and the shaft 40 is pulled up to the uppermost position is defined as an open position, and the lever 38 is raised and the shaft 40 is pushed down to the lowermost position. The position of the shaft 40 when it is performed is defined as a blocking position.

  On the other hand, when the shaft 38 is pushed down by being raised by the lever 38 and is fixed at the blocking position, the coil spring 52 urges the shaft 40 below the apparatus main body 36. At this time, the distal end 40e of the second valve portion 40c of the shaft 40 is inserted into the central flow channel 68 of the nozzle 72 by the urging force of the coil spring 52 on the shaft 40, and the O attached to the groove 88 of the tapered portion 40d. The ring 71 contacts the seat 58 of the valve body 44 of the device main body 36. As a result, the seat opening 58a is closed by the O-ring 71 of the tapered portion 40d. Also, at this time, the first valve portion 40b of the shaft 40 moves downward, and the opening of the main body side sub-path 56 provided on the inner peripheral surface of the hole 42b is opened by the Y packing 70a, the Y packing 70b, and the first packing. It is connected only to the outer peripheral surface of the valve portion 40b and the space surrounded by the hole 42b of the valve body portion 44. Further, the opening of the shaft side sub-path 60 located between the Y packing 70b and the Y packing 70c is formed by the Y packing 70a, the Y packing 70c, the outer peripheral surface of the first valve portion 40b, and the hole 42b of the valve body portion 44. Closed by the space surrounded by As a result, the opening of the main body side sub-path 56 and the opening of the shaft side sub-path 60 are shut off from each other, that is, the sub-path 62 is shut off.

  Therefore, when the shaft 40 is in the shut-off position, the seat opening 58a is closed by the second valve portion 40c of the shaft 40 abutting on the seat 58 of the apparatus main body 36, and the main path 66 is shut off. Therefore, the main beverage 32a that has flowed down the main path 66 from the beverage supply source 14 cannot flow down to the central channel 68 of the nozzle 72, and the supply of the main beverage 32a to the nozzle 72 is shut off. At this time, the opening of the main body side sub-path 56 and the opening of the shaft side sub-path 60 are shut off from each other. Therefore, since the main path 66 is shut off and the sub-path 62 is shut off, the sub-beverage 32 b flowing down from the sub-beverage supply source 15 through the main sub-path 56 cannot flow down to the shaft-side sub-path 60. The supply of the sub beverage 32b to the nozzle 72 is shut off. As described above, when the shaft 40 is fixed at the blocking position, the sub-beverage 32b is not mixed with the main beverage 32a.

  Here, when the shaft 40 is fixed at the shut-off position, the opening of the main body side sub-path 56 includes the Y packing 70a, the Y packing 70b, the outer peripheral surface of the first valve portion 40b, and the hole of the valve body portion 44. It is connected only to the space surrounded by 42b. Therefore, the distance between the groove 86a and the groove 86b in which the Y packing 70a and the Y packing 70b are respectively mounted is larger than the size of the opening of the main body side sub-path 56, that is, the opening diameter of the main body side sub-path 56.

As described above, the first valve portion 40b of the shaft 40 and the portion including the opening communicating with the main body side sub-path 56 and the hole 42b of the valve body portion 44 of the device main body 36 are the first opening / closing valve of the sub beverage 32b. The second valve portion 40c of the shaft 40 and the seat portion 58 of the valve body portion 44 of the device main body 36 function as a second on-off valve of the beverage 32.
The on-off valve for the sub-beverage 32b and the on-off valve for the main beverage 32a are opened and closed in conjunction with the up and down movement of the shaft 40, and function as the on-off valve of the present invention.

As shown in FIGS. 2 and 3, the lever 38 of the tap device 12 has a handle 90 to which an operating force is applied, and an operating portion 92 that rotates by operating the handle 90 to move the shaft 40 up and down. And a lever-type vertical movement mechanism for the shaft 40, which is constituted by a handle 90 and an operating portion 92.
The handle 90 of the lever 38 is formed of a long rod-shaped or plate-shaped member extending from the operating portion 92.
The operating portion 92 of the lever 38 is rotatably supported by the rotating shaft 82 of the shaft 40, is connected to the handle 90 at the upper portion by screwing, and the like, and is open at the bottom. An operating portion opening 92a through which the shaft 40 passes is provided on the left side surface of the lever 38 in FIG. 3, and a bottom end 92b provided with the operating portion opening 92a is, as shown in FIG. When the lever 38 is turned over by the handle 90, the lever 38 moves while contacting the outer surface of the inward flange 50 a of the large-diameter portion 50 of the apparatus main body 36, and the operating portion 92 rotates about the rotation shaft 82. It becomes a fulcrum of the case

  That is, when an operating force is applied to the handle 90 and the lever 38 is turned sideways, the shaft 40 moves vertically upward, and when the lever 38 is raised, the shaft 40 moves vertically downward. For example, the lever 38 and the shaft 40 can be connected to each other so as to form a link mechanism in which the rotation shaft 82 is a slider shaft that moves in the vertical direction. As long as the shaft 40 moves up and down due to the horizontal movement and the rising of the lever 38, any known method may be used to connect the operating portion 92 to the shaft 40. Further, contrary to the lever 38 shown in FIGS. 2 and 3, the shaft 40 may move downward when the lever 38 is turned over, and the shaft may move upward when the lever 38 rises.

As shown in FIG. 2, when the lever 38 is turned down, the shaft 40 is moved upward and is fixed at the open position. At this time, the main body side sub-path 56 and the shaft side sub-path 60 are passed through the Y packing 70b, the Y packing 70c, the outer peripheral surface of the first valve portion 40b, and the space surrounded by the hole 42b of the valve body portion 44. Are connected.
Further, as shown in FIG. 3, when the lever 38 is raised, the shaft 40 moves downward and is fixed at the blocking position. At this time, the main body side sub-path 56 is connected to the space surrounded by the Y packing 70a, the Y packing 70b, the outer peripheral surface of the first valve portion 40b, and the hole 42b of the valve body portion 44. Therefore, the sub path 62 constituted by the main body side sub path 56 and the shaft side sub path 60 is in a closed state. Furthermore, when the lever 38 is raised and the shaft 40 is fixed at the blocking position, the shaft 40 receives the elastic force of the coil spring 52 via the flange 84 so as to be pushed downward. The O-ring 71 is strongly pressed against the seat 58 and closely contacts the seat 58. Therefore, at this time, the main path 66 is also closed.

  As described above, the lever 38 is turned over and raised to move the shaft 40 up and down between the open position and the shut-off position, so that the position between the main path 66 and the central flow path 68 of the nozzle 72 is increased. The opening and blocking of the seat opening 58a and the connection and blocking of the main body side sub-path 56 and the shaft side sub-path 62 can be performed in conjunction with each other. Therefore, by operating the lever 38, the shaft 40 can be operated as an on-off valve that simultaneously opens and closes the main path 66 and the sub path 62.

As described above, according to the apparatus main body 36 of the present invention, when the sub-beverage 32b is supplied to the main path 66 from the sub-path 62 communicating with the downstream end of the main path 66, the lever 38 is used. By simply opening the main path 66 and the sub-path 62, a beverage in which the main beverage 32a and the sub-beverage 32b are uniformly mixed is poured out by a simple operation and using the tap device 12 having a simple structure. Therefore, a beverage in which different beverages are mixed can be easily and quickly poured out.
In addition, according to the tap device 12 of the beverage dispensing device 10 described above, what is caused to flow down to the sub-path 62 is not limited to the sub-beverage 32b, and any fluid can flow down. Therefore, the auxiliary beverage supply source 15 may be a fluid supply source that supplies an arbitrary fluid.

  Further, the gas used as the first or second gas supplied from the gas supply source 16a or 16b is not particularly limited, and air can be used. When preventing the main beverage 32a stored in the beverage storage container 26a or the sub-beverage 32b stored in the beverage storage container 26b from being deteriorated by oxidation or the like, the first and second gases may be made of nitrogen gas or the like. More preferably, an inert gas is used. When carbon dioxide is used as the first or second gas, the main beverage 32a in the beverage storage container 26a is pressurized by the first gas, or the secondary beverage 32b in the beverage storage container 26b is compressed by the second gas. By utilizing the fact that the liquid surface is pressurized, the carbon dioxide gas can be dissolved in the main beverage 32a or the sub-beverage 32b. That is, when the main beverage 32a or the sub-beverage 32b is a non-effervescent beverage, an effervescent beverage can be generated from the main beverage 32a or the sub-beverage 32b and the first or second gas that is carbon dioxide, and the beverage When 32 is an effervescent beverage, an effervescent beverage further containing a large amount of carbon dioxide can be produced. Furthermore, in the beverage dispensing device 10 of the present invention, the main beverage 32a or the secondary beverage 32b is an effervescent beverage, or in the beverage storage container 26a or 26b by the first gas or the second gas composed of carbon dioxide. In the case of a sparkling beverage, a beverage containing foam can be poured out as described later. As described above, the gas used for the first gas or the second gas can be appropriately changed according to the purpose and use of the user of the beverage dispensing device 10 of the present invention, and further, the air, nitrogen gas, and carbon dioxide gas can be changed. A mixed gas such as a gas containing at least one of them may be used. In addition, the first gas and the second gas used for the beverage dispensing device 10 may be the same gas or may be different from each other.

  Further, in the first embodiment, when the pressure level of the beverage by the first gas is increased or the pressure of the second gas is decreased by using the pressure adjusting unit 24a or 24b, the center flow path 68 is used. In addition, since a larger amount of the main beverage 32a is supplied compared to the sub-beverage 32b, the mixing ratio of the sub-beverage 32b in the mixed beverage of the main beverage 32a and the sub-beverage 32b is reduced. On the other hand, when decreasing the liquid surface pressure of the first gas or increasing the pressure of the second gas, the mixing ratio of the sub beverage 32b to the main beverage 32a increases.

  Further, as shown in FIGS. 2 and 3, Y packings 70 a to 70 d are used as a seal material attached to the first valve portion 40 b of the shaft 40, but the outer peripheral surface of the first valve portion 40 b and the valve body The packing is not particularly limited to the Y packing as long as the gas and the liquid can be sealed in close contact with the inner peripheral surface of the hole 42b of the portion 44. For example, V packing can be used instead of Y packing, and an O-ring can also be used. However, by using the Y packing as the sealing material, when the lever 38 is operated to move the shaft 40 up and down in the hole 42 of the apparatus main body 36, the sealing material and the hole 42b of the valve body 44 are used. Friction resistance with the peripheral surface can be reduced. Therefore, from the viewpoint that the lever 38 can be relatively easily operated, it is preferable to use Y packing as a sealant attached to the first valve portion 40b.

  As described above, according to the beverage dispensing apparatus 10 of the present invention, dispensing is performed by adjusting the liquid surface pressure of the main beverage 32a by the first gas or the liquid surface pressure of the sub-beverage 32b by the second gas. Since the mixing ratio of the auxiliary beverage 32b to the prepared beverage can be changed, the flavor of the mixed beverage can be easily changed. Further, when the pressures of the first and second gases are determined, the operator only needs to open and close the main path 66 and the sub path 62 using the lever 38, regardless of the skill of the operator and who is the operator. Also, the mixed beverage can be poured out in a short time while keeping the flavor of the mixed beverage constant every time. In addition, since the beverage dispensing device 10 of the present invention has a simple device configuration, the labor involved in installation when introducing the beverage dispensing device 10 can be reduced, and can be easily introduced. Also, it has excellent maintainability.

(Embodiment 2)
In Embodiment 1 shown in FIGS. 1 to 4 (B), the main beverage 32 a is supplied to the main path 66 of the tap device 12 and the sub-beverage 32 b is supplied to the sub-path 62, so that the main beverage 32 a Although it was possible to dispense the mixed beverage with the beverage 32b, the beverage dispense device of the present invention is not limited to this, and can be used with respect to the sub-path 62 of the tap device 12 shown in FIGS. By causing the gas to flow down, a beverage containing foam can also be poured.

  FIG. 5 shows a schematic external view of a beverage dispensing device 94 according to the second embodiment. The beverage dispense device 94 shown in FIG. 5 has the same configuration as the sub-drink supply source 15 of the beverage dispense device 10 shown in FIG. 1 as the gas supply sources 16a and 16b of the beverage dispense device 10 shown in FIG. It is replaced with a gas supply source 16c, and all other configurations are the same as those of the beverage dispensing apparatus 10 shown in FIG. Accordingly, in the following, description of the same components as those of the beverage dispensing device 10 shown in FIG. 1 will be omitted, and only the operation of the tap device 12 of the beverage dispensing device 94 shown in FIG. 5 will be described.

The gas supply source 16c of the beverage dispensing device 94 has the same configuration as the gas supply sources 16a and 16b shown in FIG. 1, and air, nitrogen gas, and carbon dioxide gas for forming a foam covering the surface of the beverage 32a. A gas storage container 22c such as a gas cylinder for storing a third gas at a high pressure, and a pressure adjusting unit (third pressure) attached to the gas storage container 22c to adjust the high-pressure gas from the gas storage container 22c to the third pressure and flow the third gas. An adjusting unit) 24c.
The pressure adjusting unit 24c includes a regulator 28c that reduces the pressure of the high-pressure gas in the gas storage container 22c to a third pressure, and a pressure gauge 30c that indicates the third pressure of the reduced-pressure third gas.
The pressure adjusting section 24c connected to the gas supply source 16c and the tap device 12 are air-tightly connected by using a supply pipe 18e that communicates the two. For this reason, the third gas that becomes a foam covering the beverage 32a is supplied from the gas supply source 16c to the tap device 12 at the third pressure. In addition, in Embodiment 2, although it has both the 1st pressure adjustment part 24a and the 3rd pressure adjustment part 24c, as mentioned later, the mixing ratio of the 3rd gas with respect to the main drink 32a is changed. In this case, the pressure of the main beverage 32a or the pressure of the third gas may be changed. Therefore, a configuration having at least one of the first pressure adjusting unit 24a and the third pressure adjusting unit 24c may be adopted.

The third pressure of the pressurized third gas supplied from the gas supply source 16c of the beverage dispensing device 94 is higher than the atmospheric pressure (0.101 MPa), and the third pressure of the pressurized third gas is converted into bubbles in the beverage 32a. Any pressure may be used as long as it can be mixed, but it is desirable that the pressure be set according to the length and diameter of the flow path of the third gas. For example, as the third pressure, the optimal pressure changes depending on the pressure loss due to the length of the flow path, the flow path diameter, and the like, it is preferable that the pressure can be adjusted as necessary, and is 0.15 MPa to 0.40 MPa. Is preferred.
In addition, when the first pressure is lower than the third pressure, the beverage 32a does not flow backward to the supply pipe 18e to which the third gas is supplied, which is preferable. Even if the magnitude and the magnitude of the third pressure are reversed, the beverage 32a may not flow back to the supply pipe 18e. Therefore, it is desirable that the pressure can be adjusted flexibly according to the actual use situation of the beverage dispensing device 94.
The first pressure of the first gas that pressurizes the beverage 32a of the beverage supply source 14 is higher than the atmospheric pressure (0.101 MPa), like the first pressure of the first gas in the first embodiment. Any pressure may be used as long as the beverage 32a in the container 26 can be supplied to the tap device 12 through the siphon pipe 34 and the supply pipe 18b according to the siphon principle. It is desirable to set in accordance with the size and the flow path diameter. For example, since the optimal pressure varies depending on the pressure loss due to the length and diameter of the flow path for the first gas and the beverage 32a, it is desirable that the first pressure can be adjusted as required. It is preferable that the pressure is from 05 MPa to 0.30 MPa.

  As shown in FIG. 6, in the beverage dispensing device 94, when the lever 38 of the tap device 12 is turned over and the shaft 40 is fixed at the open position, the first open / close valve of the sub-path 62 and the main path 66 The second on-off valve is both opened, and the beverage 32a supplied from the beverage supply source 14 under pressure and the second gas supplied from the gas supply source 16c under pressure are supplied to the main path 66 and the sub path 62, respectively. Flows down into the central flow channel 68.

  Since the spout 78 of the spouting section 48 has a small-diameter path and is provided on the side surface of the central flow path 68, the spout 78 prevents the beverage 32 a in the central flow path 68 and the bubbles 96 of the third gas from flowing. Gives high resistance. Therefore, the beverage 32 and the third gas bubbles 96 that have flowed into the central flow channel 68 are mixed in a pressurized state, and as shown in FIG. The gas becomes a mixed liquid (gas mixed beverage) of the beverage 32a and the third gas bubbles 96 dissolved in the beverage 32a.

The pressurized beverage 32a and the gaseous mixed beverage with the pressurized third gas, which have been miniaturized at the spout 78 of the spouting section 48, are poured out of the spout 78 by the pressure of the first and third gases. Then, the pressurized gas mixture beverage is released to the atmospheric pressure. As a result, the pressure of the pressurized beverage 32a is released by the pressure difference between the pressure in the path of the spout 78 and the atmospheric pressure, and the third pressurized and mixed with the beverage 32a is pressurized and compressed. The gas is also rapidly expanded in a state where the pressure is released and is in contact with the beverage 32a, so that fine and fine bubbles are generated. The generated foam is discharged from the spout 78 together with the beverage 32a while flowing in contact with the beverage 32a, flows down to the guide opening 80 through the inner wall of the guide 74, and is discharged to the beverage container 20. In this manner, the beverage with the fine layer of the third gas bubble is poured from the beverage dispensing device 94 of the second embodiment to the beverage container 20, and the beverage 32a is contained in the beverage container 20 in the beverage container 20. A fine third gas bubble that sinks below 20 and rises and covers the upper surface of the beverage 32a.
Here, the fine foam poured out from the guide opening 80 into the beverage container 20 and covering the beverage 32a in the beverage container 20 preferably has a diameter of 2 mm or less, more preferably 1 mm or less, and more preferably 0.5 mm or less. It is still more preferable that the thickness be 0.1 mm or less. The fine bubbles are preferably bubbles of a uniform size as much as possible. However, the present invention is not particularly limited, and bubbles having a size larger than 2 mm in diameter may be included, or small bubbles may be included. May be included, and an average value may be used as the diameter of the foam.
When stopping the discharge of the beverage from the guide opening 80, the lever 38 may be raised to fix the shaft 40 at the blocking position.

As described above, according to the beverage dispensing apparatus 94 shown in FIGS. 5 and 6, when gas is used as the fluid supplied from the sub-path 62 to the main path 66, the lever 38 is used to make the main path 66 and the sub-path By simply opening the passage 62, the beverage 32a and the third gas bubbles 96 can be simultaneously poured out, so that no special skill is required for foaming the beverage, and the fine foam can be easily and quickly prepared. Can be dispensed. The fluid flowing down to the tap device 12, particularly the fluid flowing down to the sub-path 62, may be a liquid or a gas as long as it is different from the beverage 32a. Different effects can be achieved depending on the type of the fluid flowing down the air.
The configuration for generating fine bubbles described above is also applied to the case where a sparkling beverage such as beer is used as the main beverage 32a (or the secondary beverage 32b) in the first embodiment shown in FIGS. Is done. That is, since the carbon dioxide gas dissolved in the main beverage 32a, which is a sparkling beverage, is released to the atmospheric pressure when it is poured out from the outlet 78 of the pouring section 48, the fineness is fine in the same manner as the above-described configuration. A mixed beverage of the main beverage 32a and the secondary beverage 32b containing foam can be poured.

  The kind of beverage used for the beverage supply source 14 of the beverage dispensing device 94 is not particularly limited as in the case of the beverage dispensing device 10 shown in FIG. 1. Even for beverages, beverages containing foam can be poured. Here, in the case where the sparkling beverage is used as the beverage 32a, even if the supply of the third gas to the sub-path 62 is extremely small due to the above-described foam generation process, the foam is included. Pouring of beverages is possible. Furthermore, even if the beverage used for the beverage supply source 14 of the beverage dispensing device 94 is a cold beverage such as ice coffee or a hot beverage such as hot coffee, the beverage containing foam is easily dispensed. be able to. In other words, according to the beverage dispensing device 94 shown in FIGS. 5 and 6, it is not necessary to control the temperature of the beverage 32a in order to generate fine foam suitable for foaming. If a cooler or a heater is provided between the container 26 and the container 26, the beverage containing foam can be poured at a desired temperature.

  In the second embodiment, when the pressure level of the beverage by the first gas is increased or the pressure of the third gas is decreased by using the pressure adjusting unit 24a or 24b, the central flow path 68 is used. In addition, since a larger amount of beverage is supplied as compared with the bubbles of the third gas, the mixing ratio of the bubbles of the third gas in the mixed liquid of the bubbles and the beverage is reduced, and the mixture is poured into the beverage container 20. The content ratio of the fine bubbles contained in the beverage is reduced. On the other hand, when decreasing the liquid surface pressure of the first gas or increasing the pressure of the third gas, the mixing ratio of the air bubbles of the third gas to the beverage increases, so that the above-described fine foam The content ratio increases.

  As described above, according to the beverage dispensing device 94 illustrated in FIGS. 5 and 6, by adjusting the liquid surface pressure of the beverage 32 a or the pressure of the third gas by the first gas, the beverage that has been dispensed is adjusted. The content ratio of the contained bubbles can be changed. Further, when the pressures of the first and third gases are determined, the operator only needs to open and close the main path 66 and the sub path 62 using the lever 38, regardless of the skill of the operator and who is the operator. In addition, the content ratio of the bubbles of the third gas contained in the beverage can be kept constant every time, and the beverage having a fine foam layer can be poured.

(Embodiment 3)
In the example illustrated in FIGS. 1 to 4B, the sub-beverage 32 b is supplied to the sub-path 62 of the tap device 12, and the main beverage 32 a is supplied to the main path 66, and the mixed beverage of the main beverage 32 a and the sub-beverage 32 b is supplied. 5 to 7, the beverage 32a containing foam could be poured out. However, in the tap device 12 shown in FIGS. Separately, by arranging a sub-beverage path for flowing the sub-beverage in the apparatus main body, it is possible to dispense a further variety of beverages.
The beverage dispensing device according to the third embodiment further includes a sub-drink supply source that supplies a sub-drink to the beverage dispensing device 10 illustrated in FIG. The apparatus main body 36 is provided with a sub-beverage path for flowing down the sub-beverage supplied from the beverage supply source 14.

  FIG. 8 shows a schematic external view of a beverage dispensing apparatus 98 according to the third embodiment. The beverage dispensing device 98 shown in FIG. 8 includes the same beverage supply source 14 and auxiliary beverage supply source 15 as shown in FIG. 1, the same gas supply source 16c as shown in FIG. The beverage supply source 14 and the tap device 100 are air-tightly communicated via a supply pipe 18c, and the sub-beverage supply source 15 and the tap device 100 are connected via a supply pipe 18b. The gas supply source 16c and the tap device 100 are air-tightly communicated via the supply pipe 18e. The beverage dispensing device 98 according to the third embodiment shown in FIG. 8 includes a first pressure regulator 24a, a second pressure regulator, and a third pressure regulator 24c. When changing the content ratio of the sub-beverage or the third gas with respect to, the pressure of the main beverage 32a, the pressure of the sub-beverage 32b, or the pressure of the third gas may be changed. Therefore, a configuration having at least one of the first pressure adjustment unit 24a, the second pressure adjustment unit 24b, and the third pressure adjustment unit 24c may be adopted.

  FIGS. 9A and 9B show a tap device 100 of the beverage dispensing device 98 of FIG. Here, FIG. 9B is a view taken along line aa of FIG. 9A. The tap device 100 shown in FIGS. 9A and 9B has a device main body 102, a lever (not shown, but having the same configuration as the lever 38 shown in FIG. 2), and a shaft 40. However, since it has the same configuration as the tap device 12 shown in FIG. 2 except for the device body 102, the valve body portion 104, and the arm portion 106, the same components are denoted by the same reference numerals, and the details thereof will be described. Detailed description is omitted.

  As shown in FIGS. 9A and 9B, device main body 102 of tap device 100 according to the third embodiment has arm portion 46, pouring portion 48, and valve body portion 104. Further, the apparatus main body 102 further has an arm 106 extending from the valve body 104 in a direction different from the direction in which the arm 46 extends. 9A and 9B, the two arms 46 and 106 extend from the valve body 104 in directions orthogonal to each other. The arm 106 is connected to one end of the supply pipe 18b, and is thereby connected to the auxiliary beverage supply source 15 via the supply pipe 18b. The valve body 104 has the same configuration as the valve body 44 in the first embodiment shown in FIG. 2 except that the arm 106 is connected.

  The arm portion 106 has the same configuration as the arm portion 46 that forms the main path 66 through which the main beverage 32a flows down, and has a pipe 108 that is bored so as to communicate with the hole 42b of the valve body 104. Are formed. The communicating portion between the pipe 108 and the hole 42b of the valve body 104 is located between the Y packing 70d and the O-ring 71 when the shaft 40 is fixed at the blocking position. Therefore, the pipeline 108 of the arm portion 106 forms a sub-beverage path 110 that flows down the sub-beverage 32b. With the arm 106 having such a configuration, when the main beverage 32a flows down the conduit 64 of the arm 46 and the auxiliary beverage 32b flows down the conduit 108 of the arm 106, the main beverage 32a The beverage 32a and the auxiliary beverage 32b are mixed with each other in the flow path 65 of the main path 66. Furthermore, when the shaft 40 is fixed at the open position, the main path 66 and the sub-beverage path 110 are opened, and the mixed beverage of the main beverage 32a and the sub-beverage 32b flows down to the central flow path of the nozzle 72. . When the shaft 40 is fixed at the blocking position, the main path 66 and the sub-beverage path 110 are closed, and the mixed beverage of the main beverage 32a and the sub-beverage 32b is placed in the flow path 65 of the main path 66. stay.

  Further, the third pressure of the gas supply source 16c connected to the tap device 100 in the third embodiment, the first pressure of the gas supply source 16a of the beverage supply source 14 that supplies the main beverage, or the sub-beverage that supplies the sub-beverage 32b By changing the second pressure of the gas supply source 16b of the supply source 15 within the above-described preferred pressure range, the mixing ratio of the third gas mixed into the main beverage 32a and the sub-beverage 32b or the main beverage 32a and the sub-beverage 32b can be changed. Thereby, the flavor of the beverage poured from the pouring section 48 to the beverage container 20 according to the ratio of fine bubbles contained in the beverage to be poured into the beverage container 20 from the pouring section 48 or the mixing ratio of the sub-beverage 32b to the main beverage 32a. Can be changed.

  In addition, in the sub-beverage supply source 15 that supplies the sub-beverage 32b of the beverage dispensing device 98 of the third embodiment, the type of the second gas that pressurizes the liquid level of the sub-beverage 32b is determined by adding the liquid level of the main beverage 32a. Like the first gas to be pressurized, it is not particularly limited, but may be appropriately used depending on the type, purpose, and application of the auxiliary beverage 32b, such as air, an inert gas such as nitrogen gas, carbon dioxide, or various mixed gases. can do.

  As described above, in addition to the sub-path 62 and the main path 66 of the tap device 100, by providing the sub-beverage path 110 in the valve body 104 of the apparatus main body 102, the beverage container can be moved from the guide opening 80 of the spouting section 48. 20, the main beverage 32a containing fine foam and mixed with the sub-beverage 32b can be poured out, and a beverage having a flavor different from that of the main beverage 32a alone can be easily poured out.

In the third embodiment, when the main beverage 32a and the sub-beverage 32b are different beverages, the first pressure of the first gas that pressurizes the main beverage 32a and the sub-pressure are set according to the combination of these beverages. It is desirable to adjust the respective pressures such that the second pressure of the second gas and the third pressure of the third gas that pressurize the beverage 32b have an optimal pressure balance with each other. In particular, the pressure loss for the first pressure and the second pressure is different from that of the first gas, the second gas, the path length and the path diameter of the main beverage 32a and the sub-beverage 32b, as well as the main beverage 32a and the sub-beverage 32b. This is because it varies depending on the physical properties such as the viscosity.
Further, the pressure balance of the fluid supplied to the tap device 100 may fluctuate depending on whether the shaft 40 is fixed at the blocking position or when the shaft 40 is fixed at the open position. Therefore, in order to prevent the main beverage 32a, the secondary beverage 32b, and the third gas from flowing back to the supply pipes 18b, 18c, and 18e, for example, the pipeline 64 of the arm 46, the pipeline 108 of the arm 106, the shaft 40 A check valve such as a duckbill valve may be attached to at least one of the main path 66 such as the shaft-side sub-path 60, the sub-beverage path 110, and the sub-path 62.

  In the above, the case where the third gas is caused to flow down to the sub-path 62 of the tap device 100 and the sub-beverage 32b is caused to flow to the sub-beverage path 110 has been described. However, the beverage pouring apparatus 10 according to the first embodiment shown in FIG. Similarly, instead of the third gas, a sub-drink different from or the same as the sub-drink 32b supplied from the sub-drink supply source 15 is supplied to the sub-path 62 of the tap device 100 shown in FIGS. You may let it flow down. In this case, as a modified example of the beverage dispensing device 98 shown in FIG. 8, similarly to the beverage dispensing device 10 shown in FIG. 1, a sub-beverage supply source 15 is provided instead of the gas supply source 16c. A sub-beverage (also referred to as a first sub-beverage for a second sub-beverage described later) 32b is supplied to the sub-path 62 of the tap device 100, and a supply pipe (not shown) is provided to the sub-beverage path 110. A new sub-beverage (not shown, hereinafter, referred to as a second sub-beverage) can be supplied from a new sub-beverage supply source (not shown, hereinafter, referred to as a second sub-beverage source). .

  The second sub-beverage supply source of the tap device 100 has the same configuration as the sub-beverage supply source 15 that communicates with the sub-path 62 of the tap device 100, and is a beverage storage container (FIG. Not-shown), a gas supply source (not shown) for supplying a fourth gas for pressurizing the liquid level of the second sub-drink stored in the beverage storage container to the beverage storage container, and a supply of the fourth gas. A pressure adjusting unit (not shown; hereinafter, referred to as a fourth pressure adjusting unit) for adjusting the pressure; The gas supply source for supplying the fourth gas, the fourth pressure regulator, and the beverage storage container for storing the second auxiliary beverage are air-tightly connected by a supply pipe (not shown). The fourth pressure adjusting unit is provided between a gas supply source that supplies the fourth gas and a beverage storage container that stores the second auxiliary beverage. In the present modification of the third embodiment, the main beverage 32a, the first sub-beverage 32b, and the second sub-beverage are supplied to the tap device 100, and a mixed beverage of these three beverages can be poured out. .

In this way, by supplying the sub-beverage to the sub-path 62 in addition to the sub-beverage path 110, it is possible to dispense the mixed beverage having more various flavors.
The first sub-beverage 32b and the second sub-beverage may be the same or different from each other, and when these two sub-beverages are the same as each other, many sub-beverages are stocked. For example, when filling a secondary beverage, the number of times can be reduced. Further, when the first sub-beverage 32b and the second sub-beverage are different from each other, as described above, it is possible to dispense a beverage having more various flavors.

In the above description, the tap device 100 has one sub-beverage path 110. However, the valve body 104 of the device main body 102 of the tap device 100 is provided with a plurality of arms each having a pipe, It may be configured to have a plurality of sub-drinking routes. In this case, by arranging a plurality of the above-mentioned second sub-drink supply sources, more sub-drinks are mixed with the main drink as compared with the case where one sub-drink path is provided in the tap device. As a result, beverages having more various flavors can be dispensed. In addition, by setting the pressing force of the gas supply source of the plurality of sub-beverage supply sources that supply the sub-beverages, more various flavor adjustments can be made for the mixed beverage that is discharged from the discharge section 48. is there.
In addition, in order to perform more various flavor adjustments for the mixed beverage that is poured from the pouring unit 48, the plurality of sub-drinks that are pressurized and supplied from the plurality of second beverage supply sources are respectively They may be different, and at least two of them may be the same. When the sub-beverage 32b is supplied to the sub-path 62, at least one of the second sub-beverages and the sub-beverage 32b may be different from each other or the same.

The cap 150 is sufficiently fixed to the large-diameter portion 148 in a fixed position of the pair of mark portions 220, 220, that is, the claw of the large-diameter portion 148 is fixed to the claw fixing hole 216a of the large-diameter portion connection portion 216. By associating the cap 150 with the set state, it is possible to visually recognize that the cap 150 is sufficiently fixed to the large-diameter portion 148 only by visual observation. For example, the cap 150 is turned 90 degrees with respect to the large-diameter portion 148 and completely screwed into the cap 150. At this time, the pair of mark portions 220 and 220 are oriented in a direction perpendicular to the width direction of the tap device 128. By doing so, the operator can visually recognize that the cap 150 and the large-diameter portion 148 are sufficiently fixed.

  The grip rotation shaft 152 of the grip 132 is the center of rotation of the grip 132 and is provided on the opposite side of the support shaft 154 of the grip 132 from the portion on the handle 134 side. The example shown in FIGS. 12, 14, and 16 is a state in which the shaft 136 is located at the blocking position. When the grip 132 is gripped from this state, the grip 132 rotates toward the handle 134 around the grip rotation shaft 152, and the support shaft 154 moves toward the cap 150. Move to the 150 side, that is, to the open position. To move the shaft 136 to the blocking position, release the grip 132 and release the support shaft 154 by rotating the grip 132 around the grip rotation shaft 152 toward the pouring unit 147 side. What is necessary is just to move to the part 147 side. As described above, in order to rotate the grip 132, the grip rotation shaft 152 is rotatable using the E-ring 222 or the like as shown in FIG. It is preferable to fix to.

  As described above, the support shaft 154 of the grip 132 moves in the longitudinal direction of the shaft 136 with the rotation of the grip 132 about the grip rotation shaft 152, and moves the shaft 136 between the open position and the shut-off position. Is moved. Therefore, the diameter of the support shaft 154 is preferably smaller than that of the support shaft hole 184 of the shaft 136 so that the support shaft 154 moves smoothly in the hole 138 in the longitudinal direction of the shaft 136. In the example shown in FIG. 12, the support shaft 154 is fixed to the grip 132 using the E-ring 222, but the support shaft 154 is fixed by a support shaft hole 184 of the cylindrical member 176 of the shaft 136 and the device. There is no particular limitation as long as the side hole 214 of the large diameter portion 148 of the main body 130 can be inserted and fixed to the grip 132.

  When the shaft 136 is located at the blocking position, the lock portion 172 including the L-shaped concave portion 156 of the grip 132 and the claw portion 166 of the handle 134 is provided at one end of the concave portion 156 of the lock portion 172. When the claw 168 is fixed, the movement of the shaft 136 from the blocking position is restricted. That is, the lock portion 172 prevents the rotation of the grip 132 when the grip 132 is farthest from the handle 134. In the example shown in FIG. 12, the claw portion 166 is attached to an end of the handle 134 on the device body 130 side so as to be rotatable around a claw rotation shaft 169, and the claw 168 of the claw portion 166 is The grip 132 is moved from one end to the other end of the L-shaped concave portion 156 provided at the upper side in the width direction. In FIG. 12, when the claw 168 of the claw portion 166 is positioned at one end on the upstream side of the concave portion 156, the grip 132 can rotate around the grip rotation shaft 152. On the other hand, when the claw 168 of the claw portion 166 is fixed to one end on the upstream side of the L-shaped recess 156, the claw 168 contacts the inner wall of the L-shaped recess 156, and the handle of the grip 132 is held. Rotation to the 134 side is hindered. By providing the lock portion 172 in this manner, the rotation of the grip 132 can be prevented, and it is possible to prevent the beverage from being poured out from the pouring portion 147 at an unexpected timing. Note that the lock portion 172, that is, the L-shaped concave portion 156 of the grip 132 and the claw portion 166 of the handle 134 only need to be able to prevent the rotation of the grip 132 to the handle 134 side. The provided position is not particularly limited to the position shown in FIG. For example, the L-shaped concave portion 156 of the grip 132 may be formed at any position as long as the side surface in the width direction of the grip 132 is provided, and the claw 168 can be fixed to one end and the other end of the L-shaped concave portion 156. The claw portion 166 may be provided at an arbitrary position on the side surface in the width direction of the handle 134, and the size of the L-shaped concave portion 156 and the claw 168 of the claw portion 166 may be appropriately changed.

When the grip 132 is completely gripped, the distal end portion of the wire 170a is in contact with the slope of the handle 134 side of the inclined plate 158a and moves beyond its upper end to a position facing the slope of the screw 224 side of the inclined plate 158a. Moving. At this time, the tip of the wire 170a collides with the inclined plate 158a due to the elastic force of the warped wire 170a, and a sound is generated. In this way, when the grip 132 is completely gripped, the collision sound between the tip portion of the wire 170a and the inclined plate 158a is generated, so that the user of the tap device 128 can grasp the grip 132 completely. It becomes easy to confirm.

The support plate 160 of the handle 134 is a plate material that is fixed to the apparatus main body 130 at the support plate fixing portion 160a and supports the handle 134.
