Abstract

PURPOSE:To enable a user to optionally select a Sunday-start or Monday-start display and to store setting information on that in a nonvolatile memory when a calendar is displayed by internal software stored in a ROM, etc. CONSTITUTION:The display mode (Sunday-start or Monday-start display) of the calendar is set by operating a pointing device over a look at a control panel for environment setting. The information is stored in the nonvolatile memory. A CPU in the case of displaying the calendar calculates the day of the week of the 1st day of the month by using an internal timer (139, 138, and 139). The read setting information is used to determine the display position of the 1st day of the month (140). The display positions of a 2nd and succeeding days are found by calculating display offsets (142 and 143).

l). This built-in software is started immediately after the power is turned on and performs various internal checks. Then, the type of the inserted disc is discriminated, and if this is a CD-I disc, the CD-I operation screen (Fig. 9) is displayed, and if this is a CD-DA disc, the CD-DA operation screen is displayed. (FIG. 10) is displayed. In the case of a CD-DA disc, the player is under the control of the built-in software, and in this state, the stationery function can operate. On the other hand, when the CD-I disc is loaded, the built-in software transfers control to the CPU 44.

The operation of this embodiment will be described in more detail below with reference to the flow chart of FIG. First, when the power switch 4 is turned on, CS of the nonvolatile RAM 51 is
It is checked whether the D file is normal (step 81). The CSD file is the information in the system ROM 50 loaded by the operating system. This check is performed by opening the CSD file in RAM. If it can be opened, the process proceeds to the next step 83. If it cannot be opened, the control proceeds to step 82.

If it cannot be opened, the RAM 51
It is determined that the CSD file has not been copied normally. This occurs because a large amount or a large capacity file already exists in the RAM 51 and the capacity for copying the CSD file cannot be secured. Therefore, in step 82, the file deletion screen (see FIG. 4C) is displayed to prompt the user to delete the file. The user erases the file,
When the capacity for copying the CSD file is secured, the internal reset is performed. After resetting, the status will be the same as immediately after power-on.

On the other hand, when the CSD file is opened, it is checked whether or not the clock and various user setting items are set (step 83). Control panel (Figure 4A and B) to set user settings
Is displayed (step 84). Trigger buttons 11a, 11b and XY device 12 are used to set items. "Exit" in the control panel
The key check ends by selecting an item.

When the key check is unnecessary, the control shifts from step 83 to step 85, the menu screen (FIG. 5A) is displayed, and the memory check (step 86) is performed. This check is set using the control panel and determines whether the environment setting data stored in RAM is correct. For example, the consistency of the checksum and the fixed value written in the RAM is used.
If the contents are correct, the control proceeds to step 87, and it is detected whether or not the inner lid 23 is closed (step 8).
7). Otherwise, control proceeds to step 88. When the backup battery is exhausted or removed, the contents of the RAM become incorrect. The RAM for storing the environment setting data may be either an area in the RAM 51 or a separate non-volatile RAM.

At step 88, default values including date / time setting values are written as environment setting data in the RAM. Then, on the screen of the display 19, a message as to whether or not the user makes settings is displayed (step 89). When the setting is not performed, that is, when the default value is acceptable, the process proceeds to step 87. On the other hand, when the user makes settings, the control panel is displayed (step 90) and the trigger button 1
The setting is performed by operating the 1a, 11b and the XY device 12. After the setting is completed, a menu screen is displayed by selecting the end item on the control panel (step 91).

Step 8 after steps 86 and 91
In 7, it is detected whether or not the inner lid 23 is closed. This detection is performed by the protrusions 23a and 23b provided on the inner lid 23.
And the detection holes 2c and 2d of the player body.
When the inner lid 23 is closed, CD-I and CD-D
Since there is a possibility that one of A is mounted, the control moves to step 92 for determining the presence or absence of the disc. On the other hand, when it is open, it is determined that the disc is not mounted, so the clock system screen (see FIGS. 6, 7, and 8) corresponding to the stationary function is displayed. Step 95
Control is transferred to.

If in step 92 it is determined that a disc is loaded, then control transfers to step 93. If it is determined that the disc is not installed,
The control moves to step 95, and the clock system screen is displayed.

In step 93, a disk check is performed. That is, the TOC recorded in the lead-in track of the innermost circumference of the disc is accessed, the type of the disc is detected from the data, and it is determined whether or not the disc can be handled. In some cases, the type of disc is determined from the index 0 of track 1. Generally, CD-I or CD-I, CD-DA or CD-DA, CD
-What is treated as I / CD-DA or CD-I / CD-DA, and others (CD-V and CD-XA
Etc.). CD-I player 1 of this embodiment
Can reproduce CD-I, CD-DA, CD-I / CD-DA, or those handled as these. If it is determined that the mounted disc can be handled, control passes to step 94, otherwise control passes to step 96.

When it is determined that the disc such as a CD-V cannot be handled by the player, a panel of a message indicating that reproduction is impossible is displayed (step 96).
It is detected whether or not a predetermined time has elapsed since this display was made (step 99), and after a predetermined time, the process proceeds to step 95 of displaying the clock system screen. In this step 99, the inner lid 23
May be the step of determining whether a has been opened. That is, you may make it loop until a disc is taken out.

As described above, the clock system screen (step 95) is of four types: clock, calendar, world clock, and menu. The user can select any screen by clicking the corresponding icon on the screen. In addition, the screen displayed when the power is turned on is the same as Step 84 or 90.
Is set as the first screen to be displayed in.

In the display of the reproduction system screen, the screen corresponding to the disc type detected in step 93 is displayed.
That is, when the disc is a CD-I disc, the CD-I screen (see FIG. 9) is displayed.
However, when the disc is a CD-DA disc, the CD-DA screen (see FIG. 10) is displayed. Also, CD-I
A CD-I screen is prepared for a disc that is treated as a / CD-DA disc. However, at this time the CD
A DA screen is also prepared, and it is possible to switch from the CD-I screen to the CD-DA screen. Further, even when the CD-DA screen is displayed and after the reproduction of the CD-DA is started, an arbitrary screen of the clock system screen can be selected by the user's screen selection. The CD-I screen is displayed and the CD-I
The same selection can be made even before the playback of (1) starts.

The inner lid 23 when the playback screen is displayed
Is opened (step 97), a clock system screen is displayed.
The screen displayed at this time is the screen last displayed in the clock system screen when the power is turned on. After the power is turned on, the reproduction system screen is directly displayed, and when there is no lastly displayed clock system screen, the screen set as the first screen displayed on the control panel is displayed.

Further, when the control shifts to step 95 and the clock system screen is displayed, even if the inner lid 23 is opened in step 98, the screen display does not change. When the inner lid 23 is closed, the disc may have been newly inserted.
The control returns to step 92 for checking the presence / absence of a disk again.

In this embodiment, the inner lid 23 of the player 1 is
