  Here, the control means records at least the last-selected application program in the recording means.

  Further, when the capacity of the application program selected last exceeds the recording capacity of the recording means, the control means causes the recording means to record only data in a simplified display form indicating the application program and causes the display means to When the simplified display form is selected, the display means displays that the card-type recording medium recording the application program corresponding to the simplified display form is attached to the attachment means.

  According to the present invention, an application program is read from the card-type recording medium, a simplified display form indicating the application program is displayed on the display means, and the application program is recorded in the storage means when the application program is executed. Therefore, once the card-type recording medium is removed from the loading unit, a program that is likely to be executed again can be executed immediately. Further, even if a card containing new contents is inserted, the application of the card inserted last time can be executed, and the necessity to prepare more card slots than necessary can be reduced as much as possible.

  Also, by recording at least the last-executed application program in the recording means, it is immediately executed without a memory card only for the last-executed application that the user wants to use immediately without consuming as much memory as possible. It becomes possible to do.

  Further, when the capacity of the application program executed last exceeds the recording capacity of the recording means, only the data of the simplified display form indicating the application program is recorded on the recording means and displayed on the display means, and the simplified display form Is selected, by displaying on the display means that the card-type recording medium recording the application program corresponding to the simplified display form is attached to the attachment means, the executed application has a large capacity or the like. Even when data cannot be recorded in the memory of the card unit, an appropriate instruction can be given when the user wants to activate the application again.

  Referring to FIG. 3, the slot portion 7 has a card connector 41 for storing the inserted card type recording medium 16 and a push for taking out the card type recording medium 16 inserted in the card connector 41. The rod 42, a discharge preparation state detection sensor 43 that detects that the push rod 42 has shifted to the discharge preparation state, and a signal detection that outputs a state signal in response to outputs from the card connector 41 and the discharge preparation state detection sensor 43. Part 44.

  The push rod 42 is, for example, a bent type push rod that discharges the card type recording medium 16 by a two-step operation, and the card type recording medium 16 is inserted into the card connector 41 in FIG. ), The connected card type recording medium 16 is prevented from being unintentionally ejected due to an erroneous operation of the push rod 42 in the protruding state. A specific embodiment of the push rod 42 that realizes such a discharge mechanism includes, for example, a commercially available push switch having a locked state and a switch member similar thereto.

  When the card-type recording medium 16 is ejected from the card connector 41, the bent portion of the push rod 42 is rotated in the direction indicated by the arrow in FIG. 3A (first operation), and FIG. As shown in FIG. 3, in a state where the push rod 42 is linear, the push rod 42 is pushed in the direction indicated by the arrow in FIG. 3B (second operation), thereby causing the eject lever (not shown) to act to operate the card. The mold recording medium 16 is discharged.

  The discharge preparation state detection sensor 43 is, for example, a reflection type optical sensor, and is disposed at a position where the bent portion of the push rod 42 is detected, as shown in FIG. 3, and by detecting the presence or absence of the bent portion of the push rod 42. Then, it is detected that the first operation of rotating the bent portion of the push rod 42 is performed and the state is shifted to the discharge preparation state, and a discharge preparation state detection signal is output to the signal detection unit 44.

  When the discharge preparation state detection signal from the discharge preparation state detection sensor 43 is input, the signal detection unit 44 performs a card detection process for detecting the connection state between the card connector 41 and the card type recording medium 16, and When the card type recording medium 16 is inserted into the connector 41, a discharge preparation state detection signal is output to the card control unit 8. Furthermore, the signal detection unit 44 detects the discharge of the card type recording medium 16 from the card connector 41 by performing a card detection process for detecting the connection state between the card connector 41 and the card type recording medium 16. When the ejection of the card type recording medium 16 from the card connector 41 is detected, an ejection confirmation signal is output to the card control unit 8.

  The card control unit 8 reads the video data composed of the video signal and the audio signal on the card type recording medium 16, reads the video data, the video signal to the video output unit 3, and the audio signal to the audio output unit 4. A reproduction process to be output respectively and a recording process to write the video signal and the audio signal output from the receiving unit 2 as video data on the card type recording medium 16 are performed.

  Further, when the ejection preparation state detection signal from the signal detection unit 44 is input, the card control unit 8 performs a communication state confirmation process for confirming a communication state with the card type recording medium 16, and the card type recording medium. 16, when an alarm is output from the speaker 6 through the audio output unit 4 and a warning is displayed on the display unit 5 through the video output unit 3 to notify the user of the warning. The user is urged to stop taking out the card type recording medium 16.

  The card control unit 8 reads an application program recorded on the card-type recording medium 16 and sends the program to the central processing unit 9 so that it can be executed. Create and send to video output unit 3. When the application program is executed, the application program is recorded in the memory 13.

  It should be noted that the current general specification of the card type recording medium 16 may be mounted on a PC-ATA card type. This is because when a PC-ATA card is used, a protection function is often not provided in the card removal operation by the push rod 42. However, the gist of the present invention is not limited to this except for the PC-ATA card type.

Next, processing for executing the application program of the card type recording medium 16 will be described. 4 to 7 are flowcharts showing processing for executing the application program of the card type recording medium 16. Here, the user is assumed to select the application program A _K assumption.

  First, the card control unit 11 confirms from the signal of the signal detection unit 44 whether or not the card type recording medium 16 is loaded in the slot unit 7 (step S1). If it is mounted, a read process from the memory 13 is performed (step S2). In this process, as shown in FIG. 7, it is confirmed whether data is written in the memory 13 (step S21). If data is written in the memory 13, the data is read from the memory 13 (step S22), and an icon is displayed on the screen of the display unit 5 (step S23). If no data is written in the memory 13, the reading process is terminated. Then, the application program is read out from the card-type recording medium 16, and an icon of the application program is displayed on the display unit 5 via the data creation unit 12, the selection unit 11, and the video output unit 3 (step S3). Although icons are displayed, submenus may be used in which option items are displayed as characters by OSD.

Here, the user uses the remote control unit 15, and selects the application program A _K (step S4). Card-type control unit 8, the application program A _K confirms whether writable all in the memory 13 (step S5), and writable, writing all the data of the application program A _K in the memory 13, the card control unit 8 sends data of the application program a _K to the central control unit 9, is executed (step S6). If the application program A _K is impossible to write all the memory 13, the card control unit 8 does nothing recorded in the memory 13, sends the data of the application program A _K to the central control unit 9 to execute (step S7).

The card control unit 8 detects whether the card type recording medium 16 is ejected from the signal of the signal detecting means 44 (step S8). When the card-type recording medium 16 is ejected, the total data of the application program A _K checks whether written all in the memory 13 (step S9). If write all, leaving the data of the last application program A _K used in the memory 13, the screen displays an icon (step S10). If not write, write only the icon data of the application program A _K in the memory 13, the screen displays the icon data (step S11).

  When the card-type recording medium 16 is not inserted into the slot portion 7 (step S1), a reading process is performed from the memory 13 (step S12). Since this reading process is the contents of the process in FIG.

The user selects the application program A _K from the operation unit 10 or the remote control unit 18 (step S13). Card control unit 13 all the data of the application program A _K confirms whether written in the memory 13 (step S14), and if it is written to execute the selected application program A _K to the central control unit 9 ( Step S15). If it is not written, “Please insert the card in which the program is recorded” is displayed on the display unit 5 as a warning display (step S16).

  In this way, the application program is read from the card-type recording medium 16 and an icon indicating the application program is displayed on the display means 5. When the application program is executed, the application program is recorded in the memory 13. Even if the recording medium 16 is removed from the slot portion 7, a program that is likely to be executed again can be executed immediately. Further, even if a card containing new contents is inserted, the application of the card inserted last time can be executed, and the necessity to prepare more card slots than necessary can be reduced as much as possible.

  Further, by recording at least the last-executed application program in the memory 13, it is immediately executed without a memory card only for the last-executed application that the user wants to use immediately without consuming as much memory as possible. It becomes possible.

  If the capacity of the application program executed last exceeds the recording capacity of the memory 13, only the icon data indicating the application program is recorded on the recording means 13 and displayed on the display unit 5, and the icon is selected. If the card type recording medium 16 in which the application program corresponding to the icon is recorded is displayed on the display unit 5, the executed application is stored in the memory 13 due to a large capacity or the like. Even when recording is not possible, an appropriate instruction can be given when the user wants to start the application again.

  It should be noted that the present invention is not limited to the above-described embodiments, and it is obvious that each embodiment can be appropriately changed within the scope of the technical idea of the present invention. In addition, the number, position, shape, and the like of the constituent members are not limited to the above-described embodiment, and can be set to a suitable number, position, shape, and the like in practicing the present invention.
