Description

  The present invention relates to a data processing apparatus capable of accessing a detachable recording medium.

  Most data processing apparatuses represented by personal computers are equipped with or connectable to a medium driving device that can access a removable recording medium. Such a medium driving device is used for storing data, exchanging data, or loading a program.

  Many recent data processing apparatuses have an automatic playback function. With the automatic reproduction function, when a recording medium is newly attached to the medium driving device, the data recorded on the recording medium is automatically reproduced, and if a program is recorded, the automatic activation is performed. Thereby, higher operability is realized.

However, the data recorded on the recording medium is not limited to data that is subject to automatic reproduction. In the conventional data processing apparatus, when a recording medium on which such data is recorded is attached to the medium driving apparatus, access to the data has to be performed by the user. For this reason, it is considered important to automatically cope with the attachment of a recording medium on which data that is not subject to automatic reproduction is recorded to the medium driving device.

Means.

  Note that the display control unit preferably causes the display device to display the hierarchical structure of the recording medium, the hierarchical structure in the storage location secured on the recording medium, or the file from the data read by the reading control unit.

  The program of the present invention has a function for realizing the data processing apparatus of the present invention.

  In the present invention, when a recording medium is attached to the medium driving device, the medium driving device is driven to read data recorded on the recording medium, and the read data is automatically displayed on the display device. . As such, the attachment is automatically handled regardless of the type of data recorded on the recording medium. For this reason, access to desired data recorded on the recording medium can be performed more easily, and high operability is realized. As a result, the user can access desired data easily and quickly.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a configuration diagram of a data processing apparatus according to this embodiment. The data processing device 1 is one in which the present invention is applied to a mobile communication terminal device such as a mobile phone or a PHS. Here, for the sake of convenience, it is assumed to be a mobile phone and will be referred to as a “communication terminal”.

  As shown in FIG. 1, the communication terminal 1 controls a radio frequency (RF) unit 101 for a mobile phone that performs frequency conversion, modulation / demodulation, and the like of a radio signal transmitted and received via an antenna AT1, and controls the entire terminal. CPU 102, program ROM 103 storing programs executed by CPU 102 and various control data, work RAM 104 used by CPU 102 for work, two display units 105 and 106, both of which are liquid crystal display devices, for example, and each display unit Display driver unit 107 for displaying images on 105 and 106, microphone 108 for sound input, speaker 109 for sound emission, operation unit 110 having various switches, and external device that can access removable external memory MD Memory adapter unit 111 and an AC adapter for receiving current from the outside And 112, a rechargeable rechargeable battery (battery) 113 is configured to include a power supply circuit 114 for supplying a current to each unit, the.

  Although not particularly illustrated, an analog audio signal output from the microphone 108 is converted into a digital audio signal by an A / D converter and then output to the CPU 102 or the RF unit 101. In addition, an analog audio signal converted by the D / A converter is output to the speaker 109 and an unillustrated earphone jack.

  The two display units 105 and 106 have different screen sizes. The screen of the display unit 105 is larger. Therefore, the display unit 105 is called a main display unit, and the display unit 106 is called a sub display unit.

  The RF unit 101 receives and processes a signal transmitted from a mobile phone network. The received signal is demodulated and output to the CPU 102, the speaker 109, and a jack (hereinafter, only the former is assumed). At the time of a telephone call, the signal is output to the speaker 109 to emit sound from the connection destination (the telephone connected to the telephone). The audio signal from the microphone 108 is modulated and transmitted via the antenna AT1. When connected to the Internet, the demodulated signal (digital data) is output to the CPU 102. Data from the CPU 102 is modulated and transmitted via the antenna AT1.

The operation unit 110 includes various switches to be operated by the user, and a detection circuit that detects operations performed by the user on the various switches.
The power supply circuit 114 monitors each output of the AC adapter 112 and the rechargeable battery 113. Thereby, it is determined whether or not current is supplied to the AC adapter 112 from an external power source (for example, an outlet), and the CPU 102 is notified of the determination result. The rechargeable battery 113 detects the voltage value and notifies the CPU 102 of it.

  The external memory MD is, for example, a small card type flash memory. In the present embodiment, when the external memory MD is newly attached to the external memory interface unit (hereinafter abbreviated as “interface unit”) 111, the data is stored as follows regardless of the type of data stored therein. Are displayed on the main display unit 105.

FIG. 2 is a diagram for explaining a method for displaying data recorded in the external memory MD.
As shown in FIG. 2, when folders (storage locations) A to C are secured in the external memory MD, and only a plurality of files are stored in the folders A to C, the top menu, which is the highest hierarchy, For each folder, the folder names and folder icons of folders A to C are displayed. FIG. 10 shows an actual display example.

  In the lower hierarchy, the file names of the files stored in each folder are displayed. In the lower hierarchy, file data is displayed. In this manner, since different data is displayed depending on the hierarchy, in this embodiment, the hierarchy and data to be displayed are currently managed by a combination of numbers.

  In FIG. 2, “0” of “M0” represents the display of the top menu, and “11 to 3” of “M11 to 3” represents the display of the menu of the folders A to C located one level below. ing. “111-3” of “M111-3” represents the display of data stored in a file located one level below.

  In this way, the depth of the hierarchy is represented by the number of numbers to be combined, and in the combination of two or more digits, the digits other than the most significant digit each represent a folder or file in the corresponding hierarchy. Thereby, for example, “M111” indicates that the data of the file (denoted as “data (1)” in the figure) stored in the folder A one level below is displayed in the folder A. The three digits of the number of digits indicate that it is the next lower layer when viewed from the top menu (the highest layer). “M” added to the head of the number (number) represents information for identifying the external memory MD itself. For this reason, in the figure, for example, the number in parentheses in “Data (1)” represents the number assigned to the file.

  In this embodiment, when the external memory MD is attached to the interface unit 111, the data recorded on the interface unit 111 is read by the interface unit 111. Regardless of the type of the data, the top menu of the external memory MD (see FIG. 10), A folder menu or file data is automatically displayed on the main display unit 105. The display makes it easier to access desired data recorded in the external memory MD. Therefore, high operability is realized, and desired data can be accessed easily and quickly for the user.

  Hereinafter, the operation of the communication terminal 1 that automatically displays the data corresponding to the attachment of the external memory MD to the interface unit 111 will be described in detail with reference to the flowcharts of the processes shown in FIGS. To do. Each process illustrated in FIGS. 3 to 9 is realized by the CPU 102 executing a program stored in the program ROM 103, for example.

  3 to 5 are flowcharts of the entire process. It shows an excerpt of the overall flow of processing executed after the power is turned on. First, the entire process will be described in detail with reference to FIGS.

  First, in step 101, initialization is executed when the power is turned on, and the communication terminal 1 is set to a predetermined setting state. In the subsequent step 102, for example, the standby screen read from the program ROM 108 is stored in the drawing area secured in the work RAM 104, and the screen is sent to the display driver unit 107 to be displayed on the main display unit 105. Similarly, the sub display unit 106 displays a standby screen. Thereafter, the process proceeds to step 103 to determine whether or not the off-hook switch is turned on. When the user operates the switch, the fact is notified from the operation unit 110 to the CPU 102, so that the determination is YES and the process proceeds to step 104. Otherwise, the determination is no and the process moves to step 112 in FIG.

  The screens displayed on the display units 105 and 106 include, for example, image data (screens and symbols) read from the program ROM 103 or image data sent from the RF unit 101 in a drawing area secured in the work RAM 104. Generated by storing. The change of the display contents is realized by sending all or part of the display contents to the display driver unit 107 and displaying them.

  In step 104, a number input screen for inputting a telephone number is displayed on the main display unit 105. In the next step 105, the number input by the number input operation (operation on the dial key) on the operation unit 110 is displayed on the main display unit 105. In step 106 where the input operation is not performed for a certain period of time, for example, connection with a telephone having a telephone number input by the user (hereinafter referred to as “connection destination” or “partner machine”) is performed. Make a call to request.

  By the above transmission, the mobile phone network side performs a process for calling the designated partner machine, and the calling side performs a process for emitting a ringing sound to notify that. Therefore, in step 107 following step 106, a ringing tone is emitted in accordance with an instruction from the mobile phone network side. The sound emission is performed until the determination in the next step 108 becomes YES by connecting to the partner machine. The process proceeds to step 109 with a YES determination.

  Note that the above transmission is performed, for example, when the CPU 102 sends necessary information to the RF unit 101 and instructs it. The ringing tone is emitted when the RF signal is received by the RF unit 101 and demodulated, and the demodulated signal is output to the speaker 109 directly or via the CPU 102.

  If the other party is busy or the telephone cannot be placed because the power is off, a signal to that effect is transmitted from the mobile phone network side. The call of the other party is terminated when the user instructs to stop the transmission. For this reason, it is not always possible to connect to the other device by making an outgoing call. However, since this is not particularly important, it is omitted here. The same applies to other cases.

  In step 109, a call process for realizing a call by exchanging audio signals with the partner machine is executed. In the next step 110, it is determined whether or not the on-hook switch is turned on. If the switch is operated by the user, the determination is YES, and after terminating the connection with the other party, that is, the call termination process for requesting the call to the mobile phone network side in step 111, the process returns to step 102 above. A standby screen is displayed on the main display unit 105. Otherwise, the determination is no and the process returns to step 109 above. As a result, a state in which a call can be made is maintained until the end of the call is requested.

  In step 112 of FIG. 4 in which the determination in step 103 is NO and the process proceeds, it is determined whether or not the function switch is turned on. If the user operates the switch, the determination is yes and the process proceeds to step 113; otherwise, the determination is no and the process proceeds to step 122 in FIG.

  The function switch is for starting a setting function related to various functions. Setting of data to be displayed when the external memory MD is attached to the interface unit 111 can be performed by operating a switch to activate a setting function. Steps 113 to 121 are executed in order to realize the setting function.

  First, in step 113, a function list screen on which settable items are arranged is displayed on the main display unit 105. In the following step 114, one item on the list is focused and selected. In the next step 115, it is determined whether or not the cursor switch is turned on. If the switch is operated by the user, the determination is YES, and the process of moving the focus position according to the type of switch operated by the user in the switch and the position of the focused item is executed in step 116. To step 117. Otherwise, the determination is no and the process moves to step 117.

  In step 117, it is determined whether or not the decision switch is turned on. If the switch is operated by the user, the determination is yes and the process moves to step 119. Otherwise, the determination is no and the process moves to step 118 to determine whether or not the clear switch is turned on. If the user operates the switch, the determination is yes and the process returns to step 102 in FIG. Otherwise, the determination is no and the process returns to step 115 above. Thus, the state in which the item to be set can be selected by operating the cursor switch is maintained until the user operates the clear switch or the decision switch.

  In step 119, it is determined whether or not the focus position item is “external memory setting”. The item is for determining the setting of data to be displayed when the external memory MD is attached to the interface unit 111. Therefore, when the user requests the setting, the determination is YES, and the external memory setting process for performing the setting is executed in step 120, and then the process returns to step 113. Otherwise, the determination is no, and in step 121, other processing for responding to selection of other items is executed, and then the processing returns to step 113. Details of the setting process will be described later.

  In step 122 of FIG. 5 in which the determination in step 112 is NO and the process proceeds, it is determined whether or not the external memory MD is newly attached to the interface unit 111. When the memory MD is attached and connected to the interface unit 111, the fact is notified from the interface unit 111 to the CPU 102. Therefore, the determination is YES and the process proceeds to step 123. The determination is no and the process returns to step 103 in FIG.

  In step 123, the value assigned to the variable TOPF is determined. If the value is 1, it is determined to that effect and the routine proceeds to step 124 where 0 is substituted into the variable GAMEN. After that, in step 125, external memory processing that enables arbitrary access to the data recorded in the external memory MD is executed, and then the process returns to step 102 in FIG.

  The variable TOPF is a variable prepared for storing a user selection result in automatic display of data in the external memory MD. The variable GAMEN is prepared for managing a hierarchy, a folder, or a file to be displayed on the main display unit 105, and 0 assigned to it indicates that the highest hierarchy (top menu) is displayed ( (See FIG. 2). Thus, a value of 0 assigned to the variable TOPF indicates that the user has set the display of the top menu.

  On the other hand, if the value assigned to the variable TOPF is 1, this is determined, and then in step 126, the value of the variable HOZON is assigned to the variable GAMEN, and then the process proceeds to step 125. If the value is 2, this is determined, and then in step 127, the value of the variable SHIYO is substituted into the variable GAMEN, and then the process proceeds to step 125.

  The variable HOZON is substituted with a combination of numbers indicating the last saved file. The variable SHIYO is assigned a combination of numbers indicating the last displayed hierarchy, folder, or file. As a result, the value 1 assigned to the variable TOPF is set by the user to display the last saved file, and the value 2 is the last displayed hierarchy, folder, or file. Represents that.

  Note that the combination of numbers (numbers) can be assigned by determining the number of bits assigned to one digit (one number) and writing a one-digit number in units of the number of bits. Since the variables HOZON and SHIYO differ depending on the external memory MD, the values are actually HOZON separately, the attached external memory MD is identified, and the corresponding values are substituted for them. . The assignment is performed, for example, when the determination in step 122 is YES, and the process proceeds to step 123 thereafter.

  The number of times of the displayed hierarchy, folder, and file is counted. The counting is performed by securing an area in the work RAM 104 and dividing the area into sub-areas in accordance with the hierarchical structure of the external memory MD. Hereinafter, the area is referred to as TABLE, and subareas in the TABLE are described using a one-dimensional array variable notation. That is, for example, a sub-area designated by a variable GAMEN value (a combination of numbers) is expressed as TABLE (GAMEN).

  If the value assigned to the variable TOPF is 1, that is determined in step 123, and then the process proceeds to step 128. In step 128, the maximum number of times stored in TABLE is searched and extracted, and a combination of numbers indicating the subareas is substituted into a variable n. In the next step 129, the value of the variable n is substituted for the variable GAMEN. Step 125 then proceeds.

  By substituting a value for the variable GAMEN in step 124, 126, 127, or 129, the content to be displayed by the attachment of the external memory MD is determined. Since the determination is performed according to the setting of the user, the user can display desired contents.

  When the external memory MD is attached for the first time, as a matter of course, the number of times is not stored in TABLE. The values to be substituted for the variables HOZON and SHIYO are not HOZON. Therefore, in such a case, a sub area for the external memory MD is secured in TABLE, and 0 is substituted for each of these variables.

FIG. 6 is a flowchart of the external memory setting process executed as step 120 described above. Next, the setting process will be described in detail with reference to FIG.
First, in step 201, a memory setting menu screen on which settable items are arranged is displayed on the main display unit 105. In the following step 201, one item on the screen is focused and selected. In the next step 203, it is determined whether or not the cursor switch is turned on. If the switch is operated by the user, the determination is YES, and the process of moving the focus position according to the type of switch operated by the user in the switch and the position of the focused item is executed in step 204. To step 205. Otherwise, the determination is no and the process moves to step 205.

  In step 205, it is determined whether the decision switch has been turned on. If the switch is operated by the user, the determination is yes and the process moves to step 207. Otherwise, the determination is no and the process moves to step 206 to determine whether or not the clear switch has been turned on. If the switch is operated by the user, the determination is yes, and the series of processing ends here. Otherwise, the determination is no and the process returns to step 203 above. Thus, the state in which the item to be set can be selected by operating the cursor switch is maintained until the user operates the clear switch or the decision switch.

  In step 207, it is determined whether the focus position item is “none”. The item is for setting the display of the top menu. Therefore, when the user requests the setting, the determination is YES, and after assigning 0 to the variable TOPF in step 208, the series of processing is terminated. Otherwise, the determination is no and the process moves to step 209.

  In steps 209 to 214, as in steps 207 and 208, a value of 1 to 3 is set in the variable TOPF depending on whether the focus position item is “final storage”, “final use”, or “number of uses”. Processing for substituting is performed. After substituting 1, 2, or 3 for the variable TOPF, the series of processing ends. In this way, the content that the user desires to display first is set.

7 to 9 are flowcharts of the external memory process executed as step 125 in FIG. Finally, the memory processing will be described in detail with reference to FIGS.
First, in step 301, data in the external memory MD designated by the value of the variable GAMEN is displayed on the main display unit 105. In the next step 302, the value of the variable GAMEN in TABLE and the number of times stored in the subarea designated by the external memory MD are incremented. In the next step 303, the type of data displayed on the main display unit 105 is determined. If the file data is being displayed, it is determined so and the process proceeds to step 304.

  In step 304, it is determined whether the user has requested editing. If the user performs an operation for the request, the determination is yes, the process proceeds to step 305, and an editing process for realizing data editing is executed. Step 306 then proceeds. Otherwise, the determination is no and the process moves to step 306.

  In step 306, it is determined whether the storage switch is turned on. If the switch is operated by the user, the determination is yes, and in step 307, the saved data is saved in the external memory MD as a file, and in the next step 308, the value of the variable GAMEN is assigned to the variable HOZON Further, in step 309, the portion corresponding to the least significant digit in the value of the variable GAMEN is erased (cleared), and then the process returns to step 301. At this time, since the least significant digit is erased, the data of the layer one level higher is displayed. On the other hand, if not, the determination is no and the process proceeds to step 310.

  In step 310, it is determined whether or not the clear switch is turned on. If the switch is operated by the user, the determination is YES, and the editing result is invalidated, that is, deleted in step 311, and the process proceeds to step 309. Otherwise, the determination is no and the process moves to step 312.

  In step 312, it is determined whether or not the external memory MD has been removed. If the user removes the external memory MD from the interface unit 111, the determination is yes, and after the value of the variable GAMEN is substituted for the variable SHIYO in step 313, the series of processes is terminated. Otherwise, the determination is no and the process returns to step 304 above. Thereby, the state which can respond to a user's request | requirement is maintained.

  In this way, in the present embodiment, when the external memory MD is removed, the display of the data is automatically terminated. This avoids the necessity for the user to display data or end the application program for editing the data, thereby improving operability.

  The value of the variable GAMEN assigned to the variable SHIYO is stored in association with the removed external memory MD. In this way, by storing a value indicating the display content (screen) last viewed for each external memory MD, the display content corresponding to the value can be automatically displayed when it is next attached. I am letting. The same applies to the variable HOZON in which the value of the variable GAMEN is substituted in step 308.

  When the folder data (other folders and files collected in the folder) is displayed in step 301, this is determined in step 303, and the process proceeds to step 314 in FIG. In step 314, one of the data icons indicating folders or files collected in the folder is focused. In the next step 315, it is determined whether or not the cursor switch is turned on. If the switch is operated by the user, the determination is YES, and the process of moving the focus position in accordance with the type of switch operated by the user in the switch and the position of the focused icon is executed in step 316. To step 317. Otherwise, the determination is no and the process moves to step 317.

  In step 317, it is determined whether or not the decision switch is turned on. If the user operates the switch, the determination is yes, and in step 318, the number of the focused icon is added to the value of the variable GAMEN as the least significant digit, and the process returns to step 301 in FIG. Otherwise, the determination is no and the process moves to step 319.

  In step 319, it is determined whether or not the clear switch is turned on. If the switch is operated by the user, the determination is yes, and 0 is substituted into the variable GAMEN in step 320, and then the process returns to step 301 in FIG. Otherwise, the determination is no and the process moves to step 321.

  In step 321, it is determined whether or not the external memory MD has been removed. When the user removes the external memory MD from the interface unit 111, the determination is YES, and after the value of the variable GAMEN is substituted for the variable SHIYO in step 322, the series of processes is terminated. Otherwise, the determination is no and the process returns to step 315. Thereby, a state in which a data icon (file or folder) can be selected is maintained.

  When the top menu (see FIG. 10) is displayed in step 301 in FIG. 7, this is determined in step 303, and the process proceeds to step 323 in FIG. In step 323, one of the folder icons indicating the folder is focused. In the next step 324, it is determined whether or not the cursor switch is turned on. If the switch is operated by the user, the determination is YES, and the process of moving the focus position according to the type of switch operated by the user and the position of the focused icon is executed in step 325. To step 326. Otherwise, the determination is no and the process moves to step 326.

  In step 326, it is determined whether the decision switch has been turned on. If the switch is operated by the user, the determination is YES, and in step 327, a combination of numbers with the most significant digit being 1 and the value of the next digit being the number of the focused icon is assigned to the variable GAMEN. Returning to step 301 of FIG. Otherwise, the determination is no and the process moves to step 328.

  In step 328, it is determined whether or not the clear switch is turned on. If the switch is operated by the user, the determination is yes and the process moves to step 330. Otherwise, the determination is no and the process moves to step 329.

  In step 329, it is determined whether or not the external memory MD has been removed. If the user removes the external memory MD from the interface unit 111, the determination is yes, and after substituting the value of the variable GAMEN for the variable SHIYO in step 330, the series of processing ends. Otherwise, the determination is no and the process returns to step 324 above. Thereby, the state in which the folder icon can be selected is maintained.

  In this way, the number of times of browsing the hierarchy, folder, or file is updated, and the combination of numbers indicating the display content (screen) that was browsed last and the combination of numbers indicating the last saved file are stored. . Thereby, when the external memory MD is attached next, the display content designated by the user can be automatically displayed.

  In the present embodiment, the present invention is applied to the communication terminal 1, but the present invention may be applied to another type of data processing apparatus. The interface unit 111 that is a device for accessing the external memory MD is mounted on the communication terminal 1, but such a device may be externally attached.

  The data in the external memory MD is automatically displayed when it is attached. However, the user may be inquired whether or not to display it, and may be displayed according to the result. . Alternatively, a condition for automatically displaying the data may be set, and the data may be displayed only for the external memory MD in which data satisfying the condition is recorded. As such, various modifications can be made.

  A program for realizing the communication terminal (data processing device) 1 as described above may be distributed by being recorded on a recording medium such as a CD-ROM, a DVD, or a removable flash memory. Part or all of the program may be distributed via a communication network such as a cellular phone network or a public network. In such a case, the user can apply the present invention to the data processing apparatus by acquiring the program and loading it into the data processing apparatus.
