Title: Music distribution-compatible portable terminal and portable terminal

Description:
TECHNICAL FIELD  
       [0001] The present invention is related to a music-delivery-available portable terminal apparatus for suitably receiving/reproducing a music delivery as to portable type wireless terminal apparatus, and also, is related to a technique capable of displaying image data in a portable terminal apparatus for reproducing music data, or for recording/reproducing music data.  
       BACKGROUND ART  
       [0002] Since communication speeds of networks are considerably increased and also high-quality compression techniques of musical data are progressed, there is a trend that network music delivery services are popularized. Several network business activities are commenced by which musical data are marketed via the Internet by a pay system, while improving protection of copyrights.  
       [0003] Conventionally, in such a case that a user purchases musical data by utilizing this network music delivery service and then listens to the purchased musical data, this user initiates a personal computer used at his home, and accesses a server of a music delivery system by connecting this personal computer to the Internet. Then, the user searches musical data which is wanted to be purchased and downloads this searched musical data. Then, when the user listens to this musical data, the user starts music playing software corresponding to software for compressing the music data, and reproduces the musical data from a speaker connected to the personal computer.  
       [0004] Also, such a case will now be considered. That is, in a recording/reproducing apparatus such as, for example, an MD (Mini Disc: registered trademark) which records/reproduces musical data, the musical data is record, or reproduced. Under such a condition that an audio data output of a CD reproducing machine is connected to the recording/reproducing apparatus by way of a cable, or the like, a music CD is reproduced by the CD reproducing machine, and the outputted audio data is recorded on the recording/reproducing apparatus. Then, the musical data recorded on the recording/reproducing apparatus is reproduced in accordance with reproducing operation of the recording/reproducing apparatus, and then, a piece of music is reproduced from a headphone, or the like, which is connected to the recording/reproducing apparatus.  
       [0005] Also, in the case that a display device is provided with a recording/reproducing apparatus, when recorded musical data is reproduced, a number of music is indicated on this display device. Since the recorded musical data is such a data used for an acoustic output, a title, an artist name, and the like of the music are not indicated on the display device without any modification. As a consequence, in such a case that the title, the artist name, and the like of the music are wanted to be indicated, this title information and the like are inputted (recorded) in correspondence with the recorded musical data, so that when the musical data is reproduced, both the title and the artist name of the music may be indicated on the display device.  
       [0006] As previously explained, in the case that the conventional network music delivery service is utilized, the user of the service is required to perform such an operation that every time the music delivery service is utilized, the user starts the personal computer to be connected to the Internet. There is a problem that the user cannot easily utilize such a network music delivery service. Also, in such a case that the user wishes to enjoy the downloaded musical data by using a portable player, there is another problem that a memory which has stored thereinto the music data is inserted into the portable player, which causes cumbersome operations.  
       [0007] The above-described problems may be solved by that a music delivery service is utilized by a wireless terminal apparatus such as a portable telephone, and also a simple type portable telephone which is known as the PHS (registered trademark) However, in portable type wireless terminal apparatus, other problems may occur which are specific to these portable type wireless terminal apparatus. That is to say, a line happens to be cut out due to conditions of wireless electromagnetic waves while musical data is downloaded, a battery is depleted, and a user is moved outside a delivery service area.  
       [0008] Also, although the conventional recording/reproducing apparatus is capable of displaying the title and the artist name of the entered music piece in correspondence with the musical data, this conventional recording/reproducing apparatus owns no such a function capable of displaying thereon image data related to the musical data. Furthermore, the conventional recording/reproducing apparatus does not also own such a function capable of displaying image data which is downloaded in combination with the musical data, and is related to this musical data.  
       [0009] As a result, there is such a problem that even if both the musical data and the image data related to this musical data are present, the image data cannot be displayed in the conventional recording/reproducing apparatus.  
       [0010] The present invention has been made to solve the above-described problems of the background art, and has a first object to provide a music-delivery-available portable terminal apparatus capable of improving a user-friendly operability when a music delivery service is utilized by a portable type wireless terminal apparatus.  
       [0011] Also, a second object of the problem is to provide a portable terminal apparatus capable of displaying image data related to musical data.

     BEST MODE FOR CARRYING OUT THE INVENTION  
     [0059] [First Embodiment] 
     [0060] Referring now to drawings, a first embodiment of the present invention will be described.  
     [0061]FIG. 1 is a front view of a music-delivery-available portable terminal apparatus according to a first embodiment of the present invention. This music-delivery-available portable terminal apparatus  1  includes a liquid crystal screen  2  for a display purpose, and an operation button group  3 . The music-delivery-available portable terminal apparatus  1  accesses via a base station (not shown) to a server of a music delivery system by employing an antenna  4  by way of a wireless manner, so that musical data can be downloaded by way of the wireless communication. The access operation to the music delivery server is carried out in such a manner that a telephone number of this server is dialed by using a simple type portable telephone function, and both an ID number and a password are entered after a line connection is established. As to entries of these ID number and password, when both the ID number and the password are entered at first time, these data may be set in such a manner that these data are stored. In the case that both the ID number and the password are set to be stored, these ID number and password need not be entered during access operations subsequent to the first access operation.  
     [0062] The downloaded musical data is stored into a memory card  5 , which is detachably mounted on the music-delivery-available portable terminal apparatus  1 . The musical data stored in this memory card  5  is reproduced by a CPU (not shown.), and then, the reproduced music may be heard by a stereo earphone  6 , a commercially-available headphone, and the like.  
     [0063]FIG. 2( a ) shows a top menu screen produced when the music-delivery-available portable terminal apparatus  1  is used to be connected to a music delivery server. In the case that musical data is downloaded, first of all, the operation button group  3  is manipulated to select “search” in order to select a piece of music. As a result, the top menu screen is advanced to a search screen of FIG. 2( b ), and then, music piece information such as a name of an artist, and a genre is entered on this search screen by employing the operation button group  3  to find out target musical data.  
     [0064]FIG. 3( a ) shows a screen when the target musical data can be searched. In the case that a user of a music delivery service purchases the musical data by employing the screen of FIG. 3( a ), the user selects “buy” and enters “decide. ” As a result, a download operation is commenced. During the download operation, a screen of FIG. 3( b ) is represented on the liquid crystal screen  2  of the music-delivery-available portable terminal apparatus  1 . On this screen, an approximated ratio (%) of the downloaded musical data is indicated by using both a numeral number and a graph. When the downloading operation of the musical data is completed, a screen of FIG. 3( c ) is displayed, which notifies the completion of the downloading operation. When the user who has confirmed this screen depresses a “line cut” button contained in the operation button group  3 , the line is cut out. However, even when the user does not know the completion of the downloading operation due to handling of other aspects, if a predetermined time duration, for example, 1 minute has elapsed after the completion of the downloading operation, then the line is automatically cut out.  
     [0065] In such a case that musical data is downloaded by way of a wireless communication by employing the music-delivery-available portable terminal apparatus  1 , there is a storage capacity of approximately 5 MB per one piece of music. As a consequence, while the musical data is downloaded, there are some possibilities that since electromagnetic wave conditions are deteriorated, a user is moved out of a delivery service area, or a battery power source is depleted, a line is cut out, and thus the musical data cannot be downloaded.  
     [0066] As to downloading operation of musical data, after an entire portion of the musical data has been downloaded, this musical data can be reproduced. Even when the musical data has been partially downloaded, this musical data cannot be reproduced. Therefore, in such a case that the downloading operation is interrupted due to the above-described aspects while this musical data is partially downloaded, the downloading operation of this musical data need be again carried out. However, if this musical data is again downloaded from the stating parts thereof, then it is a waste of communication time and of a charge required for line connection time thereof. This fact may impede popularization of the music delivery system according to this embodiment.  
     [0067] As a consequence, in accordance with this embodiment, with respect to downloading operation of the same musical data, which is carried out after the downloading operation has been firstly interrupted until a predetermined time has passed, for example within 24 hours, only such musical data related to the musical data portion after the interruption of this downloading operation is downloaded. This downloaded musical data portion is coupled to such a musical data portion which has already been downloaded in the memory card  5  before this interruption of the downloading operation. Then, the coupled musical data portions are stored into the memory card  5 . As a result, both the communication charge and the communication time are not wasted, which occurred before the above-described interruption of the downloading operation.  
     [0068] If the user does not become aware of an occurrence of such an event that the downloading operation of the musical data is interrupted but the downloading operation thereof may be restarted, then the following opportunity may occur. That is, as explained above, 24 hours has elapsed, and thus, the user must download the musical data from the first music part. As a consequence, in the music-delivery-available portable terminal apparatus  1  of this embodiment, when the interruption of the downloading operation happens to occur, as represented in FIG. 4, a download interrupt mark (namely, such a mark that musical note is cut off in illustrated example) is displayed adjacent to a battery-remaining-amount indicating mark which is displayed at an upper left corner of the uppermost stage of the liquid crystal display screen  2 . The user can recognize that the interruption of the downloading operation happens to occur under which the downloading operation of the musical data may be restarted by viewing this download interrupt mark. Also, since this download interrupt mark is displayed during the above-described 24 hours, the user also can recognize that the downloading operation of the musical data may be restarted if this download interrupt mark is being displayed.  
     [0069] In such a case that while the download interrupt mark is displayed, the user again accesses the server of the music delivery system in a manual manner, a screen shown in FIG. 5 is displayed. Since a menu of “restart download” is prepared on this screen, the user may selectively operate this “restart download” menu, so that restarting of the downloading operation is commenced. In the case that the system is arranged in such a manner that the above-explained time duration of “24 hours” is separately counted on the server and also on the terminal apparatus, there are some possibilities that a slight temporal shift may be produced between the server and the terminal apparatus. Thus, even just after the download interrupt mark is not displayed on this terminal apparatus, if the “restart download” menu shown in FIG. 5 is still left when the user accesses the server, then restarting of the downloading operation is available.  
     [0070] Since such a function is provided, user-friendly operability of the music-delivery-available portable terminal apparatus  1  may be furthermore improved. This function causes the user to set as to whether the downloading operation is restarted in the manual manner, or the automatic manner. For instance, when the music-delivery-available portable terminal apparatus  1  is located outside a delivery service area (including such a case that electromagnetic wave condition is deteriorated) while the downloading operation of the musical data is carried out, a screen indicated in FIG. 6 is displayed which inquires as to whether or not the downloading operation is restarted in the manual manner. At this time, after the user is moved to such a place where the electromagnetic wave condition may become better, the user manually selects “YES”, and thus, both an automatic access to the server is carried out, and the menu of “restart download” of FIG. 5 is automatically selected, so that the downloading operation may be restarted.  
     [0071] However, if the user turns ON a menu “set automatic restarting” on setting screens of the terminal apparatus shown in FIG. 7( a ),  7 ( b ),  7 ( c ), then such a message “download is interrupted, and wait for restarting of automatic download operation” is displayed instead of the screen shown in FIG. 6 when the user is located outside the delivery service area while the musical data is downloaded. The terminal apparatus  1  judges as to whether or not the musical data can be downloaded since the user is moved inside the delivery service area, and automatically restarts the downloading operation. As a result, when the user turns ON the automatic restart setting operation, the user can download target musical data while this user executes other works without paying his attention to such a fact that the user is located outside, or inside the delivery service area. In this case, for example, another setting operation may be alternatively carried out in such a manner that when the line connection of the automatic download restarting operation fails by a preselected time, the automatic download restarting operation is ended. Even when the automatic download restarting operation is accomplished, if the present time is located within the above-described time duration of 24 hours, then the user may restart the downloading operation in the manual manner.  
     [0072] In the case that the battery is depleted during downloading operation, such an indication “recharge battery” is displayed on the terminal screen  2 , and if the recharging operation of the battery is not commenced within  1  minute, then the power supply is automatically turned OFF, so that the downloading operation is interrupted. When the recharging operation is commenced within 1 minute, the downloading operation is also continued during this recharging operation. However, if the recharging operation is not commenced, it is brought into such a download interruption under which the downloading operation may be restarted. In this case, when the battery is recharged and then the communication is available, the terminal apparatus automatically accesses the server, so that the downloading operation is restarted.  
     [0073] There is such a case that an event happens to occur by which the user wants to interrupt the downloading operation while this downloading operation is carried out, and thus, the user himself interrupts this downloading operation. As to this interruption of the downloading operation, there are two cases. That is, the line is cut out to interrupt the downloading operation, and also while the line is still connected, the downloading operation is interrupted. For instance, when the music-delivery-available portable terminal apparatus  1  must be used as a speech communication terminal due to an occurrence of an urgent event while the downloading operation is carried out, if the downloading line is not cut out, then a line used for the speech communication cannot be connected. In this case, when the user depresses a “line cut” button during the downloading operation, a confirmation screen shown in FIG. 8 is displayed. When “YES” is selected, the line is cut out, and also the download interrupt mark shown in FIG. 4 is displayed.  
     [0074] A case that the downloading operation is interrupted without cutting out the line corresponds to such a case that while the downloading operation is carried out, the user is advanced to another site of this network and wishes to view this site. In this case, the user may enter an URL of the site to which the user wants to be advanced, or may select an URL to which a book mark has already been marked. Also in this case, while the interrupt mark shown in FIG. 4 is displayed, the user is advanced to another site. Then, as previously explained, the downloading operation is restarted in the manual manner.  
     [0075] It should also be noted that when the user is advanced to view a site, downloading operation of a view screen of this site is accomplished, and while the user views this view screen, even when the line is still connected, the line is not busy condition. As a consequence, while the user views the view screen, the terminal apparatus may be set in such a manner that the downloading operation of the musical data is automatically restarted in the background by utilizing this not-busy condition.  
     [0076] Also, there is another case that while musical data is downloaded, the user wishes to download another musical data. In this case, the user depresses a “cancel” button contained in the operation button group  3 . As a result, a screen similar to that of FIG. 8 is displayed, and when “YES” is selected, the downloading operation is interrupted, so that such a screen is displayed in which an interrupt mark is added to the screen of FIG. 2( a ). On this screen, the user searches another musical data and downloads the searched musical data. If this downloading operation of the searched musical data is not yet commenced, then the downloading operation of the musical data under interruption condition may be restarted. However, after the downloading operation of another musical data has been started, the new musical data is overwritten on the musical data under interruption condition of the downloading operation, so that the downloading operation of the musical data under interruption cannot be restarted.  
     [0077] As previously described, in the music-delivery-available portable terminal apparatus  1  according to this embodiment, since the interruption of the downloading operation is displayed by the interrupt mark, the user can confirm this interruption of the downloading operation, and thus, can recognize the necessity of restarting of the downloading operation. Also, since the music-delivery-available portable terminal apparatus  1  is arranged in such a manner that the downloading operation can be automatically restarted, and furthermore, only the remaining portion of the musical data may be merely downloaded, the user-friendly operability of the music delivery system can be improved.  
     [0078] It should also be understood that the above-described music-delivery-available portable terminal apparatus of this embodiment has been exemplified as the terminal apparatus having the simple type portable telephone function. Alternatively, a third-generation portable telephone and a fourth-generation portable telephone may be employed as the terminal apparatus.  
     [0079] [Second Embodiment] 
     [0080] Referring now to drawings, a second embodiment of the present invention will be described.  
     [0081]FIG. 9 is a front view and a block diagram as to a peripheral portion of a display unit of a portable terminal apparatus according to this embodiment. FIG. 10 is a structural diagram for indicating a data structure. FIG. 11 is a diagram for indicating a transmission/reception network.  
     [0082] First, a description is made of an arrangement of a portable terminal apparatus  10  according to this embodiment with reference to FIG. 9.  
     [0083]FIG. 9( a ) is the front view for indicating both the display unit and an operation unit of the portable terminal apparatus, and FIG. 9( b ) is the block diagram for representing an internal arrangement of the portable terminal apparatus.  
     [0084] The portable terminal apparatus  10  is arranged by an antenna  12 , a transmission/reception unit  14 , a control unit  16 , a storage unit  18 , a display unit  20 , and an operation unit  30  (see FIG. 9( b )). The antenna  12  is used to transmit/receive a wireless signal between the own portable terminal apparatus  10  and a communication apparatus such as a base station. The transmission/reception unit  14  demodulates a reception signal received by this antenna  12 , and modulates a transmission signal. The control unit  16  controls the respective units employed inside the portable terminal apparatus  10 . The storage unit  18  stores thereinto musical data, and image data, text data and music piece information data, which are related to this musical data. The display unit  20  displays thereon image data and other displayable data. The operation unit  30  corresponds to such a means for operating the portable terminal apparatus  10  and for inputting data. Also, both the above-described antenna  1  and transmission/reception unit  14  correspond to a reception unit defined in a scope of claim for a patent.  
     [0085] Furthermore, peripheral portions of the button of the operation unit  30  correspond to a direction designation button function for designating upper/lower/right/left directions. This operation unit  30  is arranged by an integral type navigation key  30   a  having a button function at a button center portion, a first button  30   b  corresponding to a push button, and a second button  30   c  corresponding to a push button. Also the above-described operation unit  30  corresponds to both a designation unit and a selection unit, which are defined in the scope of claim for the patent.  
     [0086] Then, the storage unit  18  may be realized as a storage apparatus built in the portable terminal apparatus  10 . However, in this embodiment, this storage unit  18  is explained as a storage medium  18   a  which is detachably mounted with respect to the portable terminal apparatus  10 . Although not shown in this drawing, this storage medium  18   a  is constructed by that, for instance, longitudinal/transverse sizes of a package outer shape are defined by 24 mm×32 mm, and a thickness of this package outer shape is approximately 2 mm, and also a plurality of contact terminals are equipped on a package edge portion. These plural contact terminals are employed so as to be connected to a power supply line and a signal line of the portable terminal apparatus  10 . Also, a controller, and a flash memory connected to this controller are contained in this storage medium  18   a.  This controller is employed so as to communicate with the control unit  16  of the portable terminal apparatus  10 . Musical data, image data, text data, and the like are stored into this flash memory.  
     [0087] As explained above, the storage medium  18   a  stores thereinto the musical data which is downloaded from a host sever constituting a music delivery source, and also, stores thereinto both the image data and the text data, which are downloaded in combination with this musical data, and are related to this musical data. Furthermore, the storage medium  18   a  owns a capacity (region) used to download/record these musical/image/text data.  
     [0088] Now, all data structures containing the musical data will be explained with reference to FIG. 10.  
     [0089] The overall data structure containing the musical data is constituted by a package header  50  located at a data head, musical data  52  corresponding to data used for acoustic outputs, image data  54 , text data  56 , and music piece information data  58 . This package header  50  indicates header information indicative of both an attribute of data and a data structure. The image data  54  corresponds to, for example, a jacket image, an image of an artist, and an image of a sales advertisement, and are related to the musical data  52 . The text data  56  indicates, for example, the words of the musical data  52 , and is related to the musical data  52 . The music piece information data  58  represents a title and an artist name of the musical data  52 .  
     [0090] It should also be noted that in this embodiment, the image data  54  is constituted by plurality of still image data  541 ,  542  to  54   n.  Alternatively, the image data  54  may be constituted by a plurality of moving picture data, or may be constituted by mixing still image data with mixing picture data, or may be arranged by one piece of still image data, or may be arranged by one piece of mixing picture data.  
     [0091] Also, all of these data shown in FIG. 2 indicate such a case that the image data  54  and the text data  56  are present in combination with the musical data  52 . Alternatively, all of these data shown in FIG. 2 may represent such a case that only the music data  52  is present, both the musical data  52  and the image data  54  are present, or both the musical data  52  and the text data  56  are present.  
     [0092] Next, a description will now be made of a network structure used to transmit/receive these data with reference to FIG. 11.  
     [0093] Since the portable terminal apparatus  10  executes a wireless communication with respect to the base station  70 , even when this portable terminal apparatus  10  is moved, a data communication can be carried out between the own portable terminal apparatus  10  and a host server  74  which is connected via both the base station  70  and the communication network  72 .  
     [0094] All of the data (image data  54 , text data  56 , music piece information data  58 ) which contain the above-explained musical data and image data are stored in the host server  74  every music. Since the portable terminal apparatus  10  and another communication apparatus connectable to the communication network  72  performs data communications (access), titles of music may be viewed, a musical part of the musical data  52  may be heard, and all of the data including the musical data  52  every music may be downloaded.  
     [0095] Also, since the host server  74  is also connected to the Internet, the portable terminal apparatus  10  may be connected via the host server  74  to the Internet, and may access a desirable home page and the like by designating a URL (Uniform Resource Location) and the like. It should be understood that since the host server  74  is also connectable to a computer  76  which is connected via the Internet to this host server  74 , even when this computer  76  is employed, titles of music may be viewed, a musical part of the musical data  52  may be heard, and all of the data including the musical data every music may be downloaded.  
     [0096] The description is returned to the display unit  20  of the portable terminal apparatus  10 .  
     [0097] The display unit  20  is, for instance, a color liquid crystal display device, and may change a displayed content under control of the control unit  16 . In FIG. 9( a ), an initial menu screen of the portable terminal apparatus  10  is displayed as one example. Alternatively, the image data  54 , the text data  56 , the music piece information data  58 , and the like may be displayed.  
     [0098] First, a description will now be made of the initial menu screen of the display unit  20 . A power supply pictorial (pict.)  20   a  corresponds to an indicator which indicates that a remaining energy amount of the power supply is continuously displayed when the power supply of the portable terminal apparatus  10  is turned ON. A condition pictorial  20   b  shows a reproducing condition of the musical data  52  in the portable terminal apparatus  10 . An electromagnetic wave condition pictorial  20   c  shows a strength of an electromagnetic wave received by the antenna  12 . A day/time indication  20 d represents a month, a day, a week, and time.  
     [0099] A reproduction mark  21  corresponds to a display button used to reproduce the musical data  52 . An access mark  22  corresponds to a display button used to access from the portable terminal apparatus  10  to the host server  74 . A mode mark  23  corresponds to a display button used to set a communication mode of the portable terminal apparatus  10 . A memory mark  24  corresponds to a display button employed so as to display/edit a content record on the storage medium  18   a.  A tool button  25  corresponds to an indication button used to set various setting modes of the portable terminal apparatus  10 .  
     [0100] Furthermore, a direction pictorial  20   e  shows such a condition that a direction may be designated by a navigation key  30   a.  A decision/set pictorial  20   f  represents an indication corresponding to a depression button function of a center button portion of the navigation key  30   a.  Although not shown in FIG. 9( a ) a first pictorial corresponding to the first button  30   b  is displayed in a left-sided display area of the direction pictorial  20   e,  and also, a second pictorial corresponding to the second button  30   c  is displayed in a right-sided display area of the decision/set pictorial  20   f.    
     [0101] The pictorial displays of the decision/set pictorial  20   f  and the first/second pictorials are changed in the respective screens displayed on the display unit  20 . Function pictorials which are allocated to the navigation key  30   a,  the first button  30   b,  and the second button  30   c  are displayed on the respective screens.  
     [0102] In FIG. 9( a ), since both the direction pictorial  20   e  and the decision/set pictorial  20   f  are displayed, any one of the reproduction mark  21 , the access mark  22 , the mode mark  23 , the memory mark  24 , and the tool button  25  may be selected by operating the navigation key  30   a.  Also, as to a selected mark, a circle of this selected mark becomes larger than those of other marks (reproduction mark  21  is selected in FIG. 9( a )).  
     [0103] Under this condition, in such a case that the reproduction mark  21  is determined to reproduce the musical data  52 , the push button (OK button) of the center-button portion on the navigation key  30   a  is pushed. In this case, for example, in the case that plural pieces of the musical data  52  are stored in the storage medium  18   a,  the reproducing operation of the music piece is commenced in accordance with an order of these musical data which are downloaded from the host server  74 . Alternatively, after the downloading operations have been accomplished, the music order may be arbitrarily designated, and then, the music piece may be reproduced in accordance with this designated music order.  
     [0104] The foregoing descriptions are related to the functions of the respective units and the basic indications of the display unit  20  employed in the portable terminal apparatus  10 .  
     [0105] [Displays of Image Data, Text Data, and Music Piece Information Data] 
     [0106] Referring now to FIG. 12 to FIG. 15, a description is made of displaying of the image data  54 , the text data  56  and the music piece information data  58  in the case that the musical data  52 , and also, the image data  54 , the text data  56  and the music piece information data  58 , which are related to this musical data  52 , have been stored in the storage medium  18   a  of the portable terminal apparatus  10 .  
     [0107]FIG. 12 is an explanatory diagram for indicating a method for designating a piece of music. FIG. 13 is an explanatory diagram for explaining an image data display method. FIG. 14 is an explanatory diagram for indicating a text data display method. FIG. 15 is an explanatory diagram for showing a music piece information data display method.  
     [0108] First of all, a description is made of a method for selecting from a list, the musical data  52  containing the image data  54  (similarly, containing text data  56 , and music piece information data  58 ) with reference to FIG. 12.  
     [0109]FIG. 12( a ) is a diagram for showing a menu screen related to a storage medium  18   a,  FIG. 12( b ) is a diagram for representing a PLAYLIST view, and FIG. 12( c ) is a diagram for indicating a music list within PLAYLIST. It should be noted that when the memory mark  24  is selected/determined in FIG. 9( a ), the menu screen shown in FIG. 12( a ) is displayed.  
     [0110] The menu screen shown in FIG. 12( a ) is such a screen by which a music order of the storage medium  18   a  can be edited, a memory capacity can be confirmed, and a format of the memory can be selectively designated. In this drawing, a menu “PLAYLIST edit” is selected (diagonal portion). In this case, when the push button of the center portion in the navigation key  30   a  is pushed, “select” located in the decide/set pictorial  20   f  is carried out, so that this menu screen is changed into the screen shown in FIG. 12( b ) on which the PLAYLIST view is displayed.  
     [0111] In this case, a symbol “PLAYLIST” implies a list indicative of an order of reproducing music pieces. A symbol “DP” shown at the uppermost position of the PLSYLIST view corresponds to such a PLAYLISTs on which a sequence of downloading the music data has been recorded. Subsequently, symbols “01” to “03” of PLAYLIST correspond to such PLAYLISTs in which the user of portable terminal apparatus  10  has separately designated an order of reproducing music pieces.  
     [0112] Next, for example, when PLAYLIST of symbol “03” (namely, inclined portion) is selected, the screen shown in FIG. 12( c ) is displayed. It should also be noted that a first pictorial of FIG. 12( b ) corresponds to a menu pictorial  20   h , and a second pictorial corresponds to a back pictorial  20   g . The menu pictorial  20   h  is a function capable of displaying a selection menu (will be discussed later), and the menu pictorial  20   g  is a function capable of back to one-succeeding display screen.  
     [0113] In FIG. 12( c ), a music piece list contained in PLAYLIST is displayed. For example, names of music pieces and names of artists are displayed in the order of music piece reproducing operations. It should be noted that an image data existing mark  26  (“P”) is indicated on the left side of the music piece reproducing order “1”. This image data existing mark  26  indicates that the image data  54  is attached to this music piece.  
     [0114] Under this condition, a music piece may be selected in the music piece list along upper/lower directions. Then, under such a condition that the music piece of the music piece reproducing order “1” is selected (namely, diagonal line portion), when the menu pictorial  20   h  is selected by depressing the first button  30   b , the screen shown in FIG. 13( a ) is subsequently displayed.  
     [0115]FIG. 13( a ) is a diagram for representing a selection menu, and FIG. 13( b ) is a diagram for showing a displayed image.  
     [0116] When a menu “display image” is selected (diagonal line portion) in FIG. 13( a ), as represented in FIG. 13( b ), the image data  54  attached to the musical data  52  of the reproducing order “1” selected in the above manner can be displayed. Also, in the case that there are plural pieces of the image data  54 , a plurality of these image data  54  may be switched to be displayed by depressing the push button of the center portion of the navigation key  30   a  corresponding to the decision/set pictorial  20   f  (in this case, “switching” pictorial).  
     [0117] Also, instead of the display of the above-described image data  54 , either the text data  56  or the music piece information data  58  may be similarly displayed. This display will now be explained with reference to FIG. 14 and FIG. 15. FIG. 14( a ) is a diagram for showing a selection menu, and FIG. 14( b ) is a diagram for denoting a displayed text. FIG. 15( a ) is a diagram for indicating a selection menu, and FIG. 15( b ) is a diagram for representing displayed music piece information.  
     [0118] It should also be noted that since image displays until the music piece is designated (see FIG. 12) are similar to the above-explained displays of the image data  54 , explanations thereof are omitted.  
     [0119] As indicated in FIG. 14( a ), when a menu “text select” (diagonal line portion) is selected from the selection menu, as shown in FIG. 14( b ), for example, a music note of the musical data  52  is displayed by way of a text. This displayed music note may be displayed in a scrolling manner along upper/lower directions by designating the directions of the navigation key  30   a.    
     [0120] Also, as represented in FIG. 15( a ), when a menu “music piece information display” (diagonal line portion) is selected from the selection menu, as shown in FIG. 15( b ), music piece information such as a title, an artist name, recording time, a name of a record firm, and sizes of all data involving the musical data  52 , is displayed from a top position.  
     [0121] [Displays of Image Data and Others While Musical Data is Reproduced] 
     [0122] The portable terminal apparatus  10  also owns a function by which while the musical data  52  is reproduced, the image data  54  related to the musical data  52  under reproduction is automatically reproduced.  
     [0123] In the above-described menu screen of FIG. 13( b ), after certain image data  54  is displayed, this menu screen is back to such a condition represented in FIG. 9( a ) by using the back pictorial  20   g,  and thereafter the reproducing operation of music piece is commenced. Then, when the music piece designated in FIG. 12 is reproduced, the finally displayed image data  54  is automatically displayed on the display unit  20  in FIG. 13( b ).  
     [0124] As a result, while the user reproduces the musical data  52 , this user can confirm the image data  54  by the display unit  20  at the same time.  
     [0125] Also, instead of the display of FIG. 13( b ), for example, as such a display indicated in FIG. 16, the image data  54  which is wanted to be displayed during the reproducing operation of the musical data  52  may be designated. Subsequently, this designation method will now be explained.  
     [0126]FIG. 16 is a diagram for indicating a designation of image data.  
     [0127] In FIG. 16, a different point from the designation method of the image data  54  shown in FIG. 13( b ) is such a point that a marking pictorial  20   i  is set to the first pictorial. In this case, while the image data  54  is switched/displayed, the image data  54  which is wished to be displayed may be designated by the marking pictorial  20   i  (namely, first button  30   a  is depressed). For instance, a marking  27  which is designated at a right corner is displayed on the designated image data  54 . Then, in connection with the reproducing operation of the musical data  52 , this marked image data  54  is detected, and this detected image data  54  is displayed on the display unit  20 .  
     [0128] Also, when this marking  27  is designated to a plurality of image data  54 , a plurality of such image data  54  may be designated while the musical data  52  is reproduced. In this case, the plural pieces of these image data  54  which have been designated while the musical data  52  is reproduced may be switched by a switching means to be displayed. Alternatively, a plurality of designated image data  54  may be displayed in a list form as demagnified screens (thumbnail screens).  
     [0129] In the foregoing descriptions, while the musical data  52  is reproduced, the image data  54  which is related to the musical data  52  under reproduction is automatically reproduced. In the portable terminal apparatus  10 , either the text data  56  or the music piece information data  58  may be reproduced instead of this image data  54  which is automatically reproduced This alternative case will now be described with reference to FIG. 17.  
     [0130]FIG. 17 is an explanatory diagram for indicating switching operation of display screens when musical data is reproduced.  
     [0131] When the image data  54  is displayed while the music data  52  is reproduced, a screen of the display unit  20  becomes such a screen shown in the left side of this drawing. In this case, when the switching pictorial  20   g  (namely, second button  30   c ) is selected, the text data  56  is subsequently displayed. Furthermore, when the switching pictorial  20   g  is selected, the music piece information data  58  is displayed. Then, in addition, when the switching pictorial  20   g  is selected, the display screen is back to the display of the image data  54 .  
     [0132] As previously explained, in the case that there are the image data  54 , the text data  56 , and the music piece information data  58 , which are related to the musical data  52 , these image may be switched to be displayed. However, when the image data  54  and the text data  56  are not present, no screen-switching operation to this screen is carried out.  
     [0133] In other words, since the second button  30   c  is selected while the musical data  52  is reproduced, the user may switch the image data  54 , the text data  56 , or the music piece information data  58  to display the switched data while listens to the musical data. As a consequence, even when the musical data  52  is reproduced, the user may confirm the image data  54 , the text data  56 , and the music piece information data  58 .  
     [0134] In the above-described embodiment, the musical data  52  and the image data  54  may be downloaded (recorded) to the storage medium  18   a  by the portable terminal apparatus  10 . Alternatively, these musical/image data may be downloaded to the storage medium  18   a  by such a computer  76  which is connectable to the host server  74  via the Internet. More concretely speaking, amemory writer used to record data on the storage medium  18   a  is connected to the computer  76 , and the storage medium  18   a  is inserted into the memory writer so as to be mounted thereon, so that the computer  76  may record the musical data and the image data on the storage medium  18   a.    
     [0135] Also, the storage medium  18   a  on which the data downloaded by the computer  76  in the above-described manner has been recorded may be reproduced by the portable terminal apparatus  10 .  
     [0136] While the present invention has been described in detail with reference to the specific embodiments, it is apparent by a person having ordinarily skill in the art that the present invention may be modified, changed, and substituted without departing from the technical scope and spirit of the present invention.  
     [0137] The present patent application is made based upon Japanese Patent Application No. 2001-5187 filed on Jan. 12, 2001, and also, Japanese Patent Application No. 2001-5476 filed on Jan. 12, 2001, the contents of which have been taken herein as a reference.  
     [0138] Industrial Applicability  
     [0139] In accordance with the present invention, since the music-delivery-available portable type terminal apparatus having the better user-friendly operability can be provided, the music delivery system can be furthermore popularized.  
     [0140] Also, in accordance with the present invention, both the musical data which has been downloaded from the host server constituting the music delivery source, and also the image data which is related to the musical data and has been downloaded in combination with the musical data can be read out from the storage unit, and then, can be displayed on the display unit.  
     [0141] In the case that the downloaded image data corresponds to image data which is related to, for instance, a jacket image, an image of an artist, and an image of a sales advertisement, concerning the musical data, the user of the portable terminal apparatus can refer to this image data by displaying the image data on the display unit.
