Description

BACKGROUND OF THE INVENTION1. Field of the InventionThe present invention relates to a hydrogen cartridge tank and a hydrogen consumption system to which the hydrogen cartridge tank is attached and which is supplied with hydrogen.2. Description of the Prior ArtJapanese Patent Application JP 2002-195 499 A discloses that a hydrogen tank is provided with a safety valve and a fusible alloy is disposed in the safety valve. Thus, when the ambient temperature rises due to a fire or the like, the temperature is quickly transferred to the fusible alloy, whereby the fusible alloy melts, so that the hydrogen in the hydrogen tank is quickly discharged to the outside through the safety valve, thereby preventing damage or the like to the hydrogen tank.SUMMARY OF THE INVENTIONIt is necessary to take into account the orientation of an outlet opening of the safety valve so that the gas released from the safety valve is not directed with great force to persons in the environment. However, it is expected that hydrogen cartridge tanks which are detachable and can be used in a variety of applications will be stored upright when they are detached, the displacement position, displacement angle, etc. of the tanks will be different depending on the application when they are mounted on the application, and accordingly the orientation of the outlet port of the safety valve cannot be generalized.Based on the above problem, it is an object of the present invention to provide a hydrogen cartridge tank which can suppress the effects on the environment caused by hydrogen released from a safety valve activated when the hydrogen cartridge tank is subjected to thermal influences such as flames, etc. The present invention also provides a hydrogen consumption system in which hydrogen is supplied from a hydrogen cartridge tank.Through careful studies, the inventor has found that by reducing the force of the gas released from the safety valve (reducing the release energy), the effects of the release of the gas on the environment can be reduced (thereby reducing the likelihood of problems) compared to a situation where the force is not reduced.According to a first aspect of the present invention, a hydrogen cartridge tank includes a tank body that stores hydrogen, the tank body including a container portion that stores hydrogen, a fusible plug configured to open when a predetermined temperature is reached to release the hydrogen in the container portion through a release opening, and a control member including a surface at a position facing the release opening.In the hydrogen cartridge tank according to the first aspect of the present invention, the tank body may further include a neck and a partition member, and the partition member may be disposed between the neck and the fusible plug with both ends of the partition member abutting against the control member.According to a second aspect of the present invention, a hydrogen cartridge tank further includes a tank body storing hydrogen and a housing accommodating the tank body, wherein the tank body includes a container portion storing hydrogen and a fusible plug configured to open when a predetermined temperature is reached to release the hydrogen in the container portion through a release opening, and wherein the housing includes a control member including a surface at a position facing the release opening.In the hydrogen cartridge tank according to the second aspect of the present invention, the control member may be a handle of the hydrogen cartridge tank.In the hydrogen cartridge tank according to the second aspect of the present invention, the tank body may further include a neck and a partition member, and the partition member may be disposed between the neck and the fusible plug with both ends of the partition member abutting against the control member.According to a third aspect of the present invention, a hydrogen consumption system includes a housing unit accommodating a hydrogen cartridge tank, the hydrogen cartridge tank including a tank body storing hydrogen, and the tank body including a container portion storing hydrogen, a release opening, and a fusible plug configured to open when a predetermined temperature is reached to release the hydrogen in the container portion through the release opening, and the housing unit including a control member including a surface at a position facing the release opening.In the hydrogen consumption system according to the third aspect of the present invention, the tank body may further include a neck and a partition member, and the partition member may be disposed between the neck and the fusible plug with both ends of the partition member abutting against the control member.According to the present invention, when the hydrogen tank is subjected to thermal influences of flames or the like and the fusible plug is activated, the control member can reduce the release energy of the released hydrogen, thereby suppressing the effects on the environment.BRIEF DESCRIPTION OF THE DRAWINGSThe features and advantages, and technical and economic significance of exemplary embodiments of the invention will be described below with reference to the accompanying drawings, in which like numerals designate like elements, and wherein: FIG. 1 is a diagram illustrating a configuration of a hydrogen consumption system 10; FIG. 2A is an external view of the hydrogen cartridge tank 50; FIG. 2B is a cross-sectional view taken along a direction of an axial line O of the hydrogen cartridge tank 50; FIG. 3 is a perspective view illustrating a gas release control member 100; FIG. 4 is a cross-sectional view illustrating the gas release control member 100; and FIG. 5 is a cross-sectional view illustrating a gas release control member 110.DETAILED DESCRIPTION OF EMBODIMENTS1. Basic Structure of Hydrogen Consumption SystemFirst, a basic structure of a hydrogen cartridge tank and a hydrogen consumption system, which is an application in which the hydrogen cartridge tank is mounted and hydrogen is used, will be described. Specific aspects related to the reduction of the gas release energy, which is a characteristic feature of the present invention, will be described later, and the basic structures of the hydrogen cartridge tank and the hydrogen consumption system will be described herein.FIG. 1 conceptually illustrates a configuration of a hydrogen consumption system 10 according to an embodiment. Such a hydrogen consumption system 10 includes hydrogen cartridge tanks 50 that are hydrogen supply sources, a hydrogen consumption device 20 that is a hydrogen supply target, and a control device 30. this hydrogen consumption system 10 is a system that supplies hydrogen stored in the hydrogen cartridge tanks 50 to a fuel cell 21 included in the hydrogen consumption device 20 to generate electricity. Further, in the present embodiment, the hydrogen cartridge tanks 50 are configured to be detachably attached to the hydrogen consumption device 20.This will be described in detail below.1.1. Hydrogen Cartridge TankThe hydrogen cartridge tank 50 is a container that stores the gas to be supplied (hydrogen in the present embodiment) in a liquid or gaseous state. FIGS. 2A and 2B are diagrams for describing the same. FIG. 2A is an external view of the hydrogen cartridge tank 50 (a tank body 51 contained therein is indicated by a broken line), and FIG. 2B is a cross-sectional view taken along a direction of an axial line O of the hydrogen cartridge tank 50.The tank body 51 also includes a liner 52, a reinforcing layer 53 and a protective layer 54 forming a container portion, and further includes necks 55, an opening / closing valve 56, and a fusible plug 57.1.1.1. Liner LiningThe liner 52 is a hollow member that defines an inner space in the container portion of the tank body 51 and is cylindrical in the present embodiment. The liner 52 has a body portion 52 aformed with a substantially constant diameter, openings at both ends of the body portion 52 aare narrowed by side end portions 52 bwhich are dome-shaped, and the necks 55 are disposed at openings 52 cthat are narrowed.It is sufficient that the liner 52 is made of a material that can keep what is housed in its internal space (e.g., hydrogen) without leaking, and known materials can be used. Specifically, the material may be, for example, nylon resin, a polyethylene-based resin, or metal such as stainless steel or aluminum, or the like. Of these, the material constituting the liner is preferably a synthetic resin in order to reduce the weight of the tank.The thickness of the liner 52 is preferably, but is not limited to, 0.5 mm to 3.0 mm.1.1.2. Reinforcing layerThe reinforcing layer 53 is one of the members constituting the container portion, and is composed of a plurality of sheets of fibers laminated and impregnated with cured resin. The fiber layers are composed of fiber bundles wound in multiple layers to a predetermined thickness around the outer periphery of the liner 52. The thickness of the reinforcing layer 53 and the number of turns of the fiber bundles are not particularly limited because they are determined by the required strength, but the thickness is about 10 mm to 30 mm.Fiber bundlesCarbon fibers are used as the fiber bundles for the reinforcing layer 53, and the fiber bundles have a strip shape in which the carbon fibers form bundles having predetermined cross-sectional shapes (e.g., rectangular cross-sections). The cross-sectional shape may be, but is not particularly limited to, a rectangle having a width of about 6 mm to 20 mm and a thickness of about 0.1 mm to 0.3 mm. An example of the amount of carbon fibers contained in a fiber bundle is about 36,000 carbon fibers, but this is not particularly limited thereto.Impregnating resinThe resin impregnated into the fibers (fiber bundles) and cured in the reinforcing layer 53 is not particularly limited as long as the strength of the fibers can be increased. Specific examples thereof are thermosetting resins cured by heat, such as epoxy resins containing amine- or anhydride-based curing accelerators and rubber-based reinforcing agents, unsaturated polyester resins, or the like. Another example is a resin composition containing an epoxy resin as a main agent cured by a curing agent mixed therein. Thus, the resin composition, which is a mixture, reaches and penetrates the fiber layers between the time of mixing the main agent with the curing agent and the time of curing the mixture so as to be automatically cured.1.1.3. Protective LayerThe protective layer 54 may be disposed on an outer periphery of the reinforcing layer 53 as one of the members constituting the container portion, if necessary. When the protective layer 54 is provided, for example, glass fibers are wound and impregnated with resin. The impregnating resin can be viewed in the same manner as that of the reinforcing layer 52. Thereby, the tank body 51 can be given shock resistance.The thickness of the protective layer 54 may be about 1.0 mm to 1.5 mm, but is not limited thereto.1.1.4. Necks, opening / closing valves, fusible plugsThe necks 55 are members attached to each of the two openings 52 cof the liner 52, are disposed at both ends of the liner 52 in the direction of the axial line O, and serve as openings for communication between the inside and the outside of the container portion, and valves are disposed therein. The opening / closing valve 56 is disposed in one of the necks 55, and the fusible plug 57 is disposed in the other neck 55.The material constituting the necks 55 is not particularly limited as long as the required strength is obtained, and examples thereof are stainless steel, aluminum, etc.The opening / closing valve 56 is closed when the hydrogen cartridge tank 50 is not connected to the hydrogen consumption system 10, and is opened by pressing a push rod (not shown in the drawing) when the hydrogen cartridge tank 50 is connected to the hydrogen consumption device 20 of the hydrogen consumption system 10 described later.The fusible plugs 57 are sometimes also referred to as a fusible alloy safety valve, and are a valve that opens upon reaching a predetermined temperature to release gas (hydrogen) in the container portion (liner 52). The basic shape of the fusible plug 57 is not particularly limited, and a known shape may be used. Further, the fusible plug 57 may be a metal material containing lead or tin. In addition, the melting plug 57 may melt at more than 110° C. However, it should be noted that specific shapes for controlling the hydrogen released from the fusible plug 57 will be described later.1.1.5. HousingThe housing 58 is a member enclosing a part of the tank body 51 and forming an outer shell of the hydrogen cartridge tank 50, and has a rim 59 and a handle 60.The enclosure 59 is a cylindrical member and is configured such that at least a part of the tank body 51 can be accommodated therein. In addition, the casing 59 is provided with a hole 59 aat a position facing the opening / closing valve 56 of the tank body 51 housed therein, and is configured such that the opening / closing valve 56 is accessible from the outside. In addition, the enclosure 59 is provided with a hole 59 bat a position facing the fusible plug 57 of the tank body 51, and the fusible plug 57 is accessible from the hole 59 band configured so that the hydrogen released from the fusible plug 57 can be released to the outside. That is, the housing 58 accommodates the liner 52 of the tank body 51 and accommodates the fusible plug 57 so as to be exposed (note that specific shapes, etc., with respect to the hydrogen released from the fusible plug 57 will be described later).The handle 60 is an arcuate member disposed at an end portion of the casing 59 on the side of the fusible plug 57, and a user can hold this handle 60 to support the hydrogen cartridge tank 50 and attach / remove the hydrogen cartridge tank 50 to / from the hydrogen consumption system 10.1.1.6 Otherwise,In the present embodiment, the cartridge tank 50 is a portable hydrogen tank configured to be portable, and the size and weight thereof are set from this perspective. The allowable pressure of the tank body 51 is not particularly limited, but from the perspective of being portable and yet capable of supplying a larger amount of hydrogen, the tank body may be capable of storing hydrogen at an allowable pressure of more than 20 MPa and not more than 70 MPa.In the hydrogen consumption system 10 of the present embodiment, a plurality of (e.g., three) hydrogen cartridge tanks 50 are provided, each tank body 51 being filled with hydrogen. An example of three arranged hydrogen cartridge tanks 50 is described herein and is denoted by reference numerals 50a, 50b, and 50c for differentiation. The tank bodies 51 of these hydrogen cartridge tanks 50 may all have the same capacity, or containers having different capacities may be contained.1.2. Hydrogen Consumption DeviceThe hydrogen consumption device 20 is a device that is supplied with hydrogen from hydrogen cartridge tanks 50 and receives and consumes hydrogen. As illustrated in FIG. 1, the hydrogen consumption device 20 of the present embodiment includes the fuel cell 21, supply passages 22, housing units 23, connection devices 24, an injector 25, and pressure gauges 26.An example of a hydrogen consumption device is a device that performs its purpose by generating electricity using hydrogen as one of its fuels. Examples of this include, but are not limited to, a power generation and / or storage device using a fuel cell, a fuel cell powered vehicle, and so forth.1.2.1. A fuel cellThe fuel cell 21 is a device that consumes supplied hydrogen gas and receives hydrogen from the hydrogen cartridge tanks 50 and air from an air hole not shown in the drawing to generate electricity. The specific configuration of the fuel cell 21 is not limited, and known configurations may be used.1.2.2. Supply ChannelsThe supply passages 22 are pipes that supply gas from the hydrogen cartridge tanks 50 to the fuel cell 21 and are made of pipes. In the present embodiment, each of the hydrogen cartridge tanks 50 a, 50 b, and 50 cis connected to the fuel cell 21. Here, the tubes 22 a, 22 b, and 22 cextending from the hydrogen cartridge tanks 50 a, 50 b, and 50 c, respectively, join into a single tube 22 dconnected to the fuel cell 21.1.2.3. Unit HousingsThe housing units 23 are portions in which the hydrogen cartridge tanks 50 are accommodated when the hydrogen cartridge tanks 50 are connected to the hydrogen consumption device 20. The housing units 23 are spaces in which the hydrogen cartridge tanks 50 are disposed, and are spaces each surrounded by an inner wall 23 bwith an opening 23 athrough which the hydrogen cartridge tank 50 can be inserted and removed. The connecting devices 24 are respectively disposed on the bottom walls of the housing units 23 opposite to the openings 23a.1.2.4. Terminal DevicesThe connection devices 24 are disposed at connection portions of the supply passages 22 and the tank bodies 51 of the hydrogen cartridge tanks 50, and are connected to the above-described opening / closing valves 56 of the tank bodies 51, and also control the opening and closing of the opening / closing valves 56 of the tank bodies 51. The connection devices 24 include rod-shaped push rods (not shown in the figure) disposed in the housing units 23, and when the hydrogen cartridge tanks 50 are accommodated in the housing units 23, the push rods press valve bodies disposed inside the opening / closing valves 56, thereby opening the opening / closing valves 56 to be connected to the supply passages 22.1.2.5. InjectorThe injector 25 is disposed on the supply passage 22 (in the present embodiment, on the supply passage 22 d) between the connector 24 and the fuel cell 21, and controls the supply of hydrogen to the fuel cell 21.1.2.6. Pressure Measuring DevicesThe pressure gauges 26 are pressure gauges that measure the channel internal pressure of the supply channels 22 (pressure in the pipes) between the connection devices 24 and the injector 25. Although the specific shape of the pressure gauges 26 is not particularly limited, configuration is made so that the obtained pressure value data can be transmitted to the controller 30.1.3. Control DeviceThe control device 30 is an apparatus that controls each equipment part of the hydrogen consumption system 10 to maintain proper operation, and is configured to be capable of communicating with the push rods of the connection devices 24, the injector 25, the pressure gauges 26, and so on.The control device 30 includes a central processing unit (CPU) that is a processor and performs computations, a random access memory (RAM) serving as a work area, a read only memory (ROM) serving as a storage medium, a receiving unit that is an interface through which the control device 30 receives information either wired or wireless, and a transmitting unit that is an interface through which the control device 30 transmits information either wired or wireless to the outside. The controller 30 also receives information from each piece of equipment, performs the calculations required for the operation of the hydrogen consumption system 10, and transmits control signals to the piece of equipment as needed.Such a control device 30 may typically consist of a computer.2. Hydrogen Release from the Safety Valve according to the Present InventionIt is to be understood that the hydrogen cartridge tank may be exposed to flames for any reason when connected to and / or not connected to a hydrogen consumption system. For this reason, a safety measure has been taken by using a fusible plug (safety valve) to discharge hydrogen from the tank body (tank portion) when a certain temperature is reached.At this time, hydrogen as a gas (i.e., hydrogen gas) is released from the fusible plug, and since this hydrogen gas has a considerable force, the releasing direction in conventional (fixed) hydrogen tanks is adjusted to reduce the environmental impact. However, it is expected that hydrogen cartridge tanks which are detachable and can be used for a variety of applications are stored upright when detached and stored in different arrangement positions, arrangement angles, etc. of the tanks when mounted on applications depending on the application, and accordingly the orientation of the hydrogen gas discharged from the safety valve cannot be generalized. In contrast, in the present invention, the force of the hydrogen gas released from the safety valve is reduced (the release energy is reduced), thereby reducing the effects of releasing the hydrogen gas on the environment as compared with a situation where the force is not reduced. Specific examples thereof will be described below.2.1. First Example (Mode According to Tank Body)The tank body 51 can be cited as a first concrete example of the above-mentioned hydrogen gas release of the present invention. The tank body 51 includes a gas release control member 100 in addition to the above-described basic configuration. FIG. 3 is a perspective view of the tank body 51 from a direction indicated by the arrow III in FIG. 2A. That is, FIG. 3 is a diagram centered on a portion including the lateral end portion 52 bof the tank body 51 on the side of which the fusible plug 57 is disposed. FIG. 4 is a cross-sectional view taken along the line IV-IV in FIG. 3 and the axial line O and centered on the gas release control member 100 and the vicinity thereof.As can be seen from FIGS. 3 and 4, the gas release control member 100 according to the present example is disposed in the tank body 51 and includes a release hole 101 provided in the fusible plug 57, holding members 102, a control member 103, and a partition member 104.2.1.1. Release OpeningThe release hole 101 is a hole provided in the fusible plug 57, through which hydrogen gas is released. The release hole 101 is provided in the fusible plug 57, and is a hole through which hydrogen gas is released when the fusible plug 57 is activated, and determines the direction in which the hydrogen gas is released first. In the present example, the release hole 101 is opened such that an angle θ of the hydrogen gas emission direction relative to the axial line O of the tank body 51 is 90 degrees (i.e., in a tank body radial direction that is cylindrical), as indicated by the line A in FIG. 4. It is particularly preferable that this angle is about 90 degrees, but it does not need to be exactly 90 degrees, and it is sufficient that the angle with respect to the axial line O is at least a certain angle or more. It is sufficient if θ is 45 degrees or more, preferably 60 degrees or more, but it is not limited thereto. If θ is increased to a certain degree in this manner, the energy of the hydrogen gas can be more easily reduced by extending the path in which the hydrogen gas is released and facilitating the collision of the hydrogen gas with the control member, and so on.It should be noted that the term "emission" herein means the release of gas having directivity. More specifically, the emission direction (direction of the line A) is an axial line direction of a channel forming the release opening 101.2.1.2. Holding partThe holding members 102 are parts that hold the control member 103 and the partition member 104. In the present example, the holding members 102 are plate-like members long in one direction, and two holding members 102 are disposed so as to clamp the tank body 51 from both sides in a diameter direction of the cylindrical shape thereof. More specifically, the plate-like holding members 102 are arranged such that each plate surface is in contact with the protective layer 54 and a longitudinal direction of the plates is parallel to the axial line O, the end portions extending so as to protrude toward the melting plug 57 side. One holding member 102 and the other holding member 102 of the two holding members 102 are disposed on opposite sides of the axial line O.The material constituting the holding members 102 is a material that can maintain its shape without melting even when exposed to high temperatures such as flames, etc. The material of which the support members 102 are made is preferably metal, although it is not particularly limited thereto. The same applies to the materials of the control member 103 and the partition member 104 described later.2.1.3. Control elementThe control member 103 is a member that controls the direction of hydrogen released from the release opening 101. In the present example, the control member 103 is a plate-like member that is long in a direction in which both ends in the longitudinal direction are bent by 90 degrees with respect to one side of one of the plate surfaces and are shaped such that the end portions thereof extend toward the tank body 51.Such a control member 103 is disposed so that both bent end portions thereof are respectively held by the ends of the two holding members 102 so that the space between the bent end portions extends in the diameter direction of the tank body 51. At this time, the plate surface of the control member 103 is disposed to face the release opening 101. Thus, the released hydrogen gas impinges on the surface of the control member 103, thereby reducing the release energy, and further the hydrogen gas is dispersed, whereby the effects of the released gas on the environment can be suppressed.2.1.4. Partition memberThe partition member 104 is a member that controls the direction of hydrogen released from the release opening 101. In the present example, the partition member 104 is a plate-like member that is long in one direction and is shaped such that both ends on the short sides are bent by 90 degrees toward a plate surface side (the side on which the release opening 101 is disposed).This partition member 104 is held so that a central portion in the longitudinal direction is interposed between the neck 55 and the fusible plug 57, and also both ends thereof in the longitudinal direction abut on the control member 103. Thus, a line connecting the release opening 101 and the control member 103 (line A in FIG. 4 ) and the tank portion of the tank body 51 are separated by the partition member 104, and the released hydrogen gas can be prevented from flowing toward the tank portion because it impinges on the partition member 104.2.1.5 Effects, etc.According to the gas release control member 100, when the fusible plug 57 is activated to release hydrogen gas, the hydrogen gas is discharged from the release opening 101 as shown by the arrows B in FIGS. 3 and 4, and the emitted hydrogen gas hits (collides with) the control member 103, thereby changing its direction and releasing it in directions away from the container portion. As a result, the released hydrogen gas collides with the control member 103, and the energy of release is reduced, so that the extent to which the released hydrogen gas affects the environment can be suppressed. In addition, the hydrogen gas is dispersed after colliding with the controller 103, and accordingly, its effects are further suppressed.In addition, the hydrogen gas discharged from the release opening 101 is prevented from advancing toward the tank portion side by the separator 104, and accordingly, the flames are prevented from reaching the tank portion and causing a state of further overheating even if the hydrogen gas is accompanied by, for example, flames. It should be noted that the term "emission" as used herein refers to the release of gas having directivity as described above.2.2. Second Example (Mode According to Housing)The tank body 51 and the housing 58 can be cited as a second specific example of the above-described hydrogen gas release of the present invention. In the present example, the tank body 51 and the housing 58 are provided with a gas release control member 110 in addition to the above-described basic configuration. FIG. 5 is a diagram showing the gas release control member 110 and its vicinity from the same perspective as in FIG. 4.As shown in FIG. 5, the gas release control member 110 according to the present example is disposed in the tank body 51 and the housing 58, and includes the release hole 101 provided in the fusible plug 57, the holding members 102, a control member 111, and the partition member 104. Now, the release opening 101, the holding members 102, and the partition member 104 can be regarded as the same as those in the above-described gas release control member 100 and are accordingly denoted by the same reference numerals, and description thereof will be omitted.In the present example, the control member 111 is disposed instead of the control member 103 provided in the above-described gas release control member 100. The control member 111 is provided on the casing 59 of the housing 58. Except that the control member 111 is provided for the housing 58, the shape, material, arrangement (positional relationship with respect to the release opening 101), etc. may be regarded as the same as those of the control member 103 described above.This gas release control element 110 also has the same effects as the above-described gas release control element 100.In addition, in the present example, the control member 111 can also function as the handle 60 of the housing 58, whereby the number of parts can be reduced.2.3. Third Example (Mode according to Hydrogen Consumption Device)The tank body 51 and the hydrogen consumption device 20 can be given as a third specific example of the above hydrogen gas release of the present invention. In the present example, the gas release control member includes the above release opening 101, the holding members 102, and the partition member 104. Further, in the gas release control member according to the present example, the inner wall 23 bof the housing unit 23 of the hydrogen consumption device 20 is used as a control member. That is, the hydrogen gas discharged from the release opening 101 advances in the radial direction of the container portion of the tank body 51 in the same manner as described above and collides with the inner wall 23 bof the housing unit 23 that functions as a control member. In addition, the inner wall 23 bhas a surface at a position facing the release opening 101.Thus, when the fusible plug 57 is activated and hydrogen gas is released, the hydrogen gas is discharged from the release opening 101, and the discharged hydrogen gas impinges (collides) on the inner wall 23b of the housing unit 23 functioning as a control member, thereby changing its direction and releasing it in directions away from the container portion. As a result, the released hydrogen gas collides with the control element, and the energy of release is reduced, so that the extent to which the released hydrogen gas affects the environment can be suppressed. In addition, the hydrogen gas is dispersed after colliding with the control member, thereby further suppressing its effects.In addition, the hydrogen gas discharged from the release opening 101 is prevented from advancing toward the tank portion side due to the partition member 104, and accordingly, the flames are prevented from reaching the tank portion and causing a state of further overheating even if the hydrogen gas is accompanied by, for example, flames.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
