  Embodiments of the present invention will be described below with reference to the drawings.

  In addition, the meaning of the phrase “electrically connected” used in the following description is not limited to that in which the cable 2 is directly connected to the battery, but between the cable 2 and the battery, for example, a vehicle It includes the case of being connected via the internal electrical wiring.

  The charging equipment of each of the following embodiments is used as a quick charging equipment that can charge a driving battery mounted on an electric vehicle in a short time. The charging facility can be charged at a charging speed corresponding to the selected charging mode when the user selects the charging mode. That is, not only fast charging but also medium speed charging or double speed charging can be performed. As shown in FIG. 1, the charging facility includes a main body 1 for charging, and a cable 2 extending from the main body 1 and capable of electrically connecting the main body 1 and the battery. The main body 1 includes a main main body 11 that adjusts electric power so as to be suitable for charging the battery, and an operation unit 12 for operating the main main body 11. As shown in FIG. 1, the main body 11 and the operation unit 12 may be integrated by being physically coupled (in addition, the main body 11 and the operation unit 12 may be integrated completely, for example, both may be provided in one casing). May be physically separated and separated as shown in FIG. In FIG. 2, only the operation unit 12 is illustrated.

  The main body 11 is also called a “power supply panel” and includes a power conversion unit, a management electronic circuit, and the like (not shown). The power conversion unit is a part for converting electric power taken from outside (for example, commercial AC power) into DC power suitable for charging a battery mounted on an electric vehicle, and transmitting the power to the battery via the cable 2. For example, a rectifier, a transformer, an inverter, etc. are provided.

  The management electronic circuit is a part that performs signal processing and the like in order to cooperate with the power conversion unit and the operation unit 12. Specifically, it processes the information such as the amount of battery power transmitted from the electric vehicle and issues an instruction to send power corresponding to the information, or the power conversion unit by an instruction to start and stop charging from the operation unit 12 Or instructing the display 121a1 of the operation unit 12 to display the charging status.

  In addition to the above, the main body 11 can be provided with means having various functions as required, such as a lightning protection circuit.

  The operation unit 12 is formed to have a size that is at least smaller in the vertical direction than the main body 11, and is provided integrally (see FIG. 1) or separately (see FIG. 2) in the main body 11. This is a part for performing the charging operation. The separate type operation unit 12 shown in FIG. 2 is also referred to as a “charging stand” (different from the “charging stand” in the “background art” column). The operation unit 12 includes an operation unit main body 121 for operating the main main body unit 11 by a user of the charging facility, and a cable support unit 122 provided in the operation unit main body 121. When the operation unit 12 is separated as in the embodiment shown in FIG. 2, a stand 123 for installing the operation unit main body 121 on the installation surface G is used.

  The operation unit 12 includes an operation panel 121a including a display 121a1, a charge start button 121a2, a charge stop button 121a3, and an emergency stop button 121a4, and a connector storage unit 121b. The operation panel 121a is provided on the front side of the operation unit main body 121, and the connector storage part 121b is provided on the same side. The emergency stop button 121a4 is for emergency stop of the charging facility in the event of a fire, and the emergency stop button 11a is also provided on the front side of the main body 11.

  In the embodiments shown in the drawings, a display 121a1, a charge start button 121a2, and a charge stop button 121a3 are provided separately. The display 121a1 is a touch panel. Therefore, the charging operation can be performed by the user touching the display 121a1 without providing the charging start button 121a2 and the charging stop button 121a3.

  In the embodiments shown in the drawings, the connector storage portion 121b is provided in the operation portion main body 121. However, the present invention is not limited to this. For example, the connector storage portion 121b is provided in the stand 123 of the “charging stand” in the embodiment shown in FIG. It may be.

  Since the main body unit 1 includes the main main body unit 11 and the operation unit 12, only the means having a minimum function necessary for an operation of charging the battery by the user who performs the charging operation is provided on the operation unit 12. Since the other means only has to be provided in the main body part 11, the operation part 12 can be made compact, and the conventional main body part and the operation part are completely integrated. Compared to equipment, it is advantageous because of its high degree of freedom in arrangement.

  Since the installation location of the charging facility is basically outdoors, the operation unit 12 has a waterproof structure. The outer shape of the operation unit 12 is a substantially square shape with the rear side chamfered in a plan view, and a trapezoidal shape with a narrow front side in a side view. Therefore, the upper surface 121c of the operation unit 12 is a slope that goes down to the front side. Therefore, for example, rainwater or the like does not collect on the upper surface 121c. The shape of the operation unit 12 is not limited to that shown in the drawings, and can be implemented in various shapes such as a cylindrical shape or a triangular roof shape on the upper surface 121c.

  The operation unit 12 can be integrated with the main body unit 11 by being physically coupled by various means such as bolting. For example, as in the embodiment shown in FIG. 1, the side surface of the main body portion 11 and the side surface of the operation portion 12 can be in contact with each other, or the side surface of the main body portion 11 and the back surface of the operation portion 12 can be in contact with each other. However, the present invention is not limited to this, and by providing means for physically coupling the main body 11 and the operation unit 12, it can be integrated in various ways. It should be noted that when uniting in this way, the operation unit 12 can be operated at a position where a user can reach, more specifically, a position where both a standing user and a user in a wheelchair can reach. It is desirable to form the space S <b> 1 below the operation unit main body 121 by providing the panel 121 a and providing the operation unit main body 121 at a predetermined distance from the installation surface G of the operation unit 12.

  Note that the “installation surface G of the operation unit 12” is a surface on which the main body 11 is installed in the case where the main body 11 and the operation unit 12 are integrated as in the embodiment shown in FIG. In the case where the operation unit 12 is separated from the main body unit 11 as in the embodiment shown in FIG. 2, the surface on which the operation unit 12 itself is installed is indicated. Point to.

  When the operation unit 12 is provided separately from the main body unit 11, the stand 123 is provided so as to protrude from the lower surface 121d of the operation unit 12, as shown in FIG. The stand 123 is formed of a pipe material, and the lower end portion is enlarged to form an installation portion 123a. The operation portion 12 is installed on the installation surface G by embedding the installation portion 123a in the installation surface G or using anchor bolts. Can be fixed to. In addition, when the operation part 12 is made into a different body, of course, it is necessary to electrically connect the main body part 11 and the operation part 12 using a power supply cable and a communication cable. Further, as in the case of the integrated case described above, the operation panel 121a of the operation unit 12 is located at a position where the user's hand can reach, more specifically, a position where both a standing user and a wheelchair user can reach. In addition, it is desirable to form the space S <b> 1 below the operation unit main body 121 by providing the operation unit main body 121 at a predetermined distance from the installation surface G of the operation unit 12.

  A plurality of operation units 12 can be electrically connected to one main body unit 11. Therefore, it is possible to charge a plurality of electric vehicles sequentially (at the same time when the main body portion is compatible). In the embodiment shown in FIGS. 1 and 2, since simultaneous charging is impossible, when two or more electric vehicles are connected to the cables 2... The automobile is in a state where a charge reservation has been made, and after the completion of the charging of one vehicle, the charging is sequentially started in the order in which the reservation was made. Therefore, the user does not have to wait for the completion of charging of the other electric vehicle, but connects the cable 2 to the charging terminal of his / her own electric vehicle, makes a charge reservation, and completes charging, for example, shopping. Etc. can effectively use the waiting time (details will be described later). In addition, since the single main body 11 can support a plurality of electric vehicles, the cost of the entire charging facility system can be reduced.

  As described above, the electrical connection of the plurality of operation units 12 to 12 with respect to one main body unit 11 is not limited to the case where the operation unit 12 is provided separately from the main body unit 11, and is integrated. But it is possible. In the embodiment shown in FIG. 1, a maximum of four operation units 12 can be integrally attached to one main body 11.

  Here, when the operation unit 12 is provided separately from the main body unit 11, for example, when installing this charging facility in a parking lot, only the operation unit 12 is installed in the parking space, The main body 11 can be installed in a place where it does not become necessary. Therefore, the space can be used effectively, and the charging facility can be installed without problems even in a narrow parking lot where there is not enough space. Moreover, since commercial power before voltage transformation (step-down) is introduced into the main body 11, it is dangerous. Therefore, installing the main body 11 away from the user can provide a safe environment for the user.

  Whether the operation unit 12 is provided integrally with the main body unit 11 or a separate unit, the space S1 is at least below the operation unit body 121 in the body unit 1. Exists. Since the space S1 exists in this manner, even if the user is a person on a wheelchair, for example, the user can work close to the operation unit and the workability of the user is improved. Therefore, this charging facility can meet the recent demand for universal design.

  The cable 2 protrudes from the main body 1 (more specifically, the operation unit main body 121 of the operation unit 12). As the cable 2, a captyre cable in which a plurality of core wires (electric wires) are collectively covered is used. A connector 21 having a well-known structure is provided at the tip of the cable 2 so as to be electrically connected to the battery by connecting to a charging terminal of the electric vehicle. The cable 2 is provided with a communication cable as well as a power cable for sending power for charging the battery from the main body 11. The communication cable transmits information transmitted from an electric vehicle, such as the amount of battery electricity and the occurrence of charging abnormality, to the main body 1 side. By processing the information in the main body part 1 (main main body part 11), power is supplied from the main body part 1 (main main body part 11) to the battery of the electric vehicle with the power corresponding to the information, or charging is performed. You can stop.

  The main body 1 is provided with a cable support 122 that supports the cable 2. In the embodiments shown in the drawings, the cable support portion 122 is provided integrally with the operation portion main body 121, and a part of the cable 2 is disposed therein.

  The cable support portion 122 extends from the main body portion 1 and suspends the cable 2 with a first support portion 122a whose distal end is located above the proximal end, and is proximal to the distal end of the first support portion 122a. And a second support part 122b whose distal end is located outward with respect to the proximal end.

  The second support portion 122b is formed to extend in a radial direction (horizontal direction away from the first support portion 122a) centered on the extending direction of the first support portion 122a and obliquely upward. In the embodiment shown in each figure, a base portion 122b1 formed so as to extend linearly obliquely upward and an arch portion 122b2 formed in a semicircular shape above this base portion 122b1 are combined, These are fixed to the first support part 122a. With this configuration, the second support portion 122b can support the cable 2 while maintaining strength. The curvature of the arch portion 122b2 is determined in consideration of the rigidity of the cable 2 or the core wire of the cable 2 so as not to be subjected to excessive stress. The second support portion 122b is fixed to the first support portion 122a in a positional relationship that is most suitable for the installation location of the charging facility. More specifically, the angle of the circumferential direction of the 2nd support part 122b with respect to the 1st support part 122a is set and fixed.

  The cable 2 is disposed inside the arch portion 122b2. Since the cable 2 has a semicircular shape in the second support portion 122b, the cable 2 is not easily stressed by bending, and the possibility that the core wire (electric wire) constituting the cable 2 is disconnected can be reduced. The base portion 122b1 is a portion that receives the weight of the cable disposed in the arch portion 122b2, and an illumination portion 122b11 that is lit at night or the like is provided on the lower surface.

  The cable support portion 122 is fixed to the operation portion main body 121. However, the configuration is not limited thereto, and the cable support portion 122 may be configured to be rotatable with respect to the operation portion main body 121, or the first support portion 122a. However, the second support portion 122b may be configured to be rotatable. Moreover, it is good also as a structure which can expand-contract the 1st support part 122a or the 2nd support part 122b.

  Next, a method for operating the charging facility will be briefly described. First, a user removes the connector 21 from the connector storage part 121b of the operation part main body 121, and connects the connector 21 to the charging terminal of an electric vehicle. And the lock lever 21a provided in the connector 21 is pulled, and the said connection state is fixed. When this fixing is performed, it becomes possible to energize for charging.

  Then, the user presses the charge start button 121a2 on the operation panel 121a to start charging. When the charging mode (rapid, medium speed, or double speed) can be selected, charging is started after the user touches the display 121a1 that is a touch panel to select the charging mode. The state of charging is displayed on the display 121a1. Charging is automatically terminated when a predetermined charging state is reached, but can be forcibly terminated by the user pressing the charging stop button 121a3.

  When charging is completed, the connector 21 is removed from the charging terminal of the electric vehicle and returned to the connector storage part 121b of the operation part main body 121.

  Hereinafter, a configuration for effectively using the charging waiting time will be described. The operation unit 12 of the embodiment shown in FIG. 1 and FIG. 2 (hereinafter referred to as “this embodiment”) is an information providing unit 3 for providing the user with information about facilities existing around the charging facility. It has. A configuration including the information providing unit 3 is shown in FIG. The information providing unit 3 includes at least a required charging time deriving unit 31 and an information extracting unit 32, and the information extracted by the information extracting unit 32 is output (displayed) on a display 121a1 serving as an output unit. The information providing unit 3 is provided with output control means 33 for controlling the output (display) content of the display 121a1.

  In the present embodiment, the information providing unit 3 is provided in the operation unit 12. However, the information providing unit 3 is not limited thereto, and may be provided anywhere in the main body unit 1. Therefore, the main body 11 may be provided, or the main body 11 and the operation unit 12 may be provided with the means for configuring the information providing unit 3 dispersedly.

  Further, each of the required charging time deriving unit 31, the information extracting unit 32, and the output control unit 33 is not necessarily a separate device (hardware), and the same device may serve as both. . Further, the management electronic circuit may be responsible for some or all of the functions of the information providing unit 3.

  The required charging time deriving means 31 connects the cable 2 to the electric vehicle, measures the voltage value and current value after energization is possible, and according to the charging mode (rapid, medium speed, double speed), The time required for the battery to reach a predetermined charging state (hereinafter referred to as “time required for charging”) is obtained. In the present embodiment, the state where the battery is 80% charged is regarded as the completion of charging.

  More specifically, the required charging time deriving means 31 is transmitted through the cable 2 connected from the electric vehicle, and needs to have an amount of electricity required until the battery is charged 80%. Calculate the required charging time from the amount of charge and the time-dependent change in voltage and current during charging. (Note that the required charging time is calculated without calculation, such as by referring to a table. Is also good). In the present embodiment, the amount of charge required until 80% charge is calculated based on the amount of electricity of the 80% charged battery and the amount of battery electricity at the current time (when charging). It is calculated by.

  In the present embodiment, a plurality of electric vehicles can be charged sequentially, so that when another electric vehicle is being charged, a charge reservation state is established. In this case, since charging has not yet started and the current value cannot be measured, for example, the required charging time is obtained by estimating from the charging mode. However, in this method, the calculation accuracy of the required charging time is lowered. Therefore, in order to improve the calculation accuracy of the required charging time, immediately after the cable 2 is connected to the electric vehicle, power supply to another electric vehicle being charged from another operation unit 12 at that time is temporarily performed. During this period, it is preferable to measure the voltage value and the current value by supplying power to the electric vehicle just connected to the cable 2 for a short time to determine the required charging time in an interrupt process.

  The information extracting unit 32 includes an information reading unit 321. This information extraction means 32 is information about facilities such as stores that exist around the charging facility and can be moved back and forth based on the required charging time obtained by the charging required time deriving means 31 by the user of the charging facility ( (Hereinafter referred to as “facility information”).

  In the example shown in FIG. 4, after the user selects each selection condition of the moving means, age group, and sex on the display 121 a 1 that is a touch panel, the information extracting means 32 (more specifically, the information reading means 321) It is assumed that facility information suitable for the selected content is extracted (pattern for extracting facility information after selection by the user / first pattern). On the other hand, regardless of such a selection, the information extraction means 32 extracts all facility information that allows the user to go back and forth during the required charging time at the same time that the cable 2 is connected to the electric vehicle and can be energized. (A pattern / second pattern in which the user selects after the facility information is extracted). In the following, first, the first pattern will be described.

  Here, “extracting facility information based on the required charging time” includes not only what the user can go back and forth within the required charging time but also what can go back and forth in the time slightly longer than the required charging time. It is. For example, it is assumed that the excess width for the “slightly exceeded time” corresponds to, for example, several minutes added to the required charging time or several percent of the required charging time. The added time may be set in advance in the information extraction unit 32, or may be set each time when the user operates the touch panel.

  In the present embodiment, a plurality of electric vehicles can be charged sequentially, so that when another electric vehicle is being charged, a charge reservation state is established. In that case, among other electric vehicles, a reservation waiting time that is a time in which the charge required time is accumulated although charging priority is earlier than that of its own electric vehicle (the electric vehicle on which the charge reservation is made), and charging The information extraction means 32 (more specifically, the information reading means 321) extracts facility information on the basis of a waiting time that is a time obtained by adding the required charging time obtained by the required time deriving means 31.

  The information providing unit 3 may include an information storage unit 34 in which the facility information extracted by the information extraction unit 32 is stored in advance, or the facility information to be extracted may be telecommunications such as the Internet connected to a charging facility. You may provide the external information acquisition means 35 for acquiring from the charging equipment outside via a circuit | line. The information storage means 34 and the external information acquisition means 35 may be provided with only one or both of them. For example, the information storage means 34 in the charging facility is used as a main information source of facility information, and is complementary. Alternatively, the external information acquisition means 35 may be used to acquire information from outside the charging facility.

  The facility information obtained by the information extraction unit 32 (more specifically, the information reading unit 321) from the information storage unit 34 or the external information acquisition unit 35 includes at least location information (for example, an address or the latitude of the location and the location). Longitude) must be included. This location information is stored in, for example, a location information reference unit (not shown) provided in the information storage unit 34 or the external information acquisition unit 35, and the information extraction unit 32 refers to this location information reference unit. It can be used to obtain facility information including location information that meets the reference conditions.

  Here, the processing by the information extraction means 32 will be specifically described. Based on the required charging time obtained by the required charging time deriving means 31 and the speed of the moving means selected by the user on the touch panel (described later), the information extracting means 32 obtains the distance that the user of the charging facility can move. .

  As described above, with respect to the speed of the moving means referred to by the information extracting means 32 when determining the distance that the user can move, one speed is determined in advance, particularly in the case of walking or cycling. Alternatively, a plurality of speeds corresponding to the age group and sex may be determined, and the user may select an age group or sex on the touch panel so that one corresponding speed is determined. .

  Then, based on the movable distance and the position information of the charging facility (except for the case where the charging facility is movable, this information does not change because it is normally in a fixed position) Find the user's movable range. The location information of the charging facility is input to the information providing unit 3 in advance when the charging facility is installed, or the address or latitude and longitude of the location of the charging facility obtained by a GPS system provided in the information providing unit 3, for example. Information.

  Then, the information reading means 321 obtains the facility information included in the movable range from the information storage means 34 or the external information acquisition means 35. At that time, the facility information is selected based on the location information stored in the location information reference unit. In addition to this, in the first pattern embodiment, the user has selected (such as information on the age group or gender of the user or the person who wants to obtain facility information) that the user has selected (described later) on the touch panel. Facility information is extracted based on the narrowed down information. The extracted facility information is output (displayed) on the display 121a1 by the output control means 33.

  As described above, the information extraction unit 32 performs the two-stage information processing of obtaining the range in which the user can move after obtaining the distance that the user can move, but is not limited thereto. The information extraction unit 32 may directly (in one step) perform information processing for obtaining facility information. As this one-stage information processing, for example, the facility information is assumed to include necessary time information related to the time required for going back and forth by each moving means, and this necessary time information is stored in the information storage means 34 or the external information obtaining means. 35, which is stored in a necessary time information reference unit (not shown) provided in 35, and the information extraction means 32 refers to the necessary time information reference unit, thereby including facility information including necessary time information that meets the reference condition. Can be mentioned.

  Next, display examples of the display 121a1 in the case where the information extraction unit 32 is set to the first pattern in the present embodiment are shown in FIGS. FIG. 4A shows a screen display during battery charging, in which the amount of electricity of the battery at the time of display is displayed as a percentage based on the electric capacity of the battery. In the illustrated example, only the amount of electricity is displayed, but the time required to reach a predetermined charging state obtained by the required charging time deriving means 31 may be displayed together. Further, it may be displayed whether charging is performed by quick charging or medium-speed charging, and a voltage value and a current value during charging may be displayed here. When another electric vehicle is being charged, a charge reservation is displayed on the display 121a1 (not shown). In that case, the reservation waiting time may be displayed.

  In the screen display shown in FIG. 4A, a touch button “go to spot search” is displayed. When the user touches this touch button, the output control means 33 switches to the screen display shown in FIG. Here, a touch button for selecting a moving means used for the user to move to the surrounding facility is displayed. In the illustrated example, three types of movement means “walk”, “car”, and “train” can be selected. However, the situation of the installation location of the charging facility (for example, the movement prepared to be rented at the installation location) Depending on the type of means, various other moving means such as bicycles and minibikes can be displayed.

  When the user selects the moving means, the output control means 33 switches to a screen display as shown in FIG. Here, the user or the person who wants to obtain facility information is selected as a child, an adult, or an elderly person. And if a user selects this, it will switch to a screen display as shown in FIG.4 (D). Here, a user or a person who wants to obtain facility information selects a man or a woman.

  After the selection, the output control means 33 switches to a screen display as shown in FIG. In this state, calculation for displaying the next screen is performed by the information extraction means 32. After this calculation is completed, the screen display is changed to that shown in FIG. In this screen display, the distance that the user can go back and forth corresponding to the required charging time is displayed in a circle on the map, and is extracted by the information extraction means 32 (more specifically, the information reading means 321) inside and outside the circle. A mark (rectangular part in the figure) indicating the selected facility is displayed. At the same time, the movable distance and the movable time, and the name of the facility and the distance from the installation location of the charging facility are also displayed.

  In FIG. 4F, the circular display is a single circle corresponding to the moving means selected by the user on the touch panel. However, the circular display is not limited to this, and corresponds to a plurality of moving means. It may be a concentric circle. Of course, depending on the topography around the place where the charging facility is installed (the presence of undulations, rivers, and the sea), the distance that the user can go back and forth may be displayed in a shape other than a circle. Further, only the mark indicating the facility may be displayed without displaying the distance that the user can go back and forth.

  When the user touches and selects a mark indicating a facility displayed on the map of FIG. 4E, detailed information of the selected facility is displayed (not shown). As one display of this detailed information, in this embodiment, as shown in FIG. 4G, a QR code related to the selected facility is displayed on the display 121a1. The user can read the displayed QR code with a portable terminal.

  FIG. 4H is an example in which information corresponding to the QR code is displayed on the screen of the user's mobile terminal. In this example, a free coffee ticket that can be used at a coffee shop is displayed. In this way, it is possible to attract customers by partnering with facilities that exist around the charging equipment, and it is possible to increase the added value of the charging equipment that provides such facility information. It can be activated.

  Next, the second pattern will be described regarding the information extraction means 32 extracting facility information. In this second pattern, for example, based on the required charging time and the speed of the fastest moving means, the information extracting means 32 (more specifically, the information reading means 321) can be moved by the user of the charging facility. The maximum distance is obtained and the corresponding facility information is obtained in advance from the information storage means 34 or the external information acquisition means 35. Then, facility information is selected based on the moving means selected by the user on the touch panel and the above-described narrowing information, and the result is displayed on the display 121a1 by the output control means 33. In this second pattern, since information is extracted in a prospective manner before the user is selected, the user's selection is more effective than the pattern (first pattern) in which facility information is extracted after the user is selected. The processing time after selection can be shortened, and as a result, the time until the facility information is displayed on the display 121a1 may be shortened.

  As another configuration described so far, a printer may be provided in the information providing unit 3 so that facility information can be printed out.

  Moreover, it is good also as what displays the advertisement of the facility which exists in the circumference | surroundings of a charging equipment on the display 121a1 in the idle time of a charging equipment, when the charge is not performed.

  In addition, in this embodiment, the information on the facility that can go back and forth is displayed based on the required charging time, but in addition, the factory that predicts the battery life from the charging status of the battery, and can perform the expected battery replacement time and replacement work Dealer information can also be displayed on the display 121a1.

  Further, a transmission unit may be provided in the information providing unit 3. When the transmission means is provided, for example, the user is charging the receiving means provided in advance in the facility around the charging facility or the mobile terminal (such as a mobile phone) held by the user of the charging facility. By sending and displaying information about the battery charging progress, it is easier for the user to obtain the battery charging progress, and prompts the user who has approached battery charging to return to the charging facility it can.

Finally, the above is summarized from the viewpoint of processing performed by each means. The following steps are performed. Note that the following steps do not necessarily have to be processed in the order of description, and may be overlapped in time or partly replaced.
(1) A step in which the required charging time deriving means 31 obtains a required time until the battery to be charged reaches a predetermined charging state based on the voltage value and current value of the cable 2 during charging.
(2) The information extraction means 32 having the information reading means 321 is located in the vicinity of the charging facility, and the charging facility user can go back and forth based on the required charging time determined in (1). Extracting information.
(3) The step of causing the output control means 33 to display options for the user on the display 121a1.
(4) A step in which the information extraction means 32 selects information corresponding to the option selected by the user in (3) from the facility information extracted in (2).
(5) A step in which the output control means 33 displays the information selected in (4) on the display 121a1.
