(Hereinafter referred to as "driver") and means for storing the driver (hereinafter referred to as "driver storage element") are replaced with a driver for driving the storage medium to be changed, or the driver storage element itself is added to the device to cope with the situation.

The technology of recent card-type storage media (hereinafter referred to as IC cards) is in the process of growth, and storage media used include those using semiconductor memories such as magneto-optical disks, hard disks and flash memories. Among them, some IC cards have no means for controlling the storage elements in the storage medium.
On the other hand, in a device such as a digital camera or a notebook computer in which a package tends to be miniaturized, a removable storage medium is indispensable as well as a built-in storage medium. From these two facts, it is expected that an IC card having no storage element control means will be effective for further downsizing of the above-mentioned devices.

[0004]

However, in a device that tends to be miniaturized, the selection of a storage medium to be used is easily affected by the trend of the storage medium. Also, when a plurality of storage media conventionally used and a plurality of new types of storage media are used in the apparatus at the same time, or when upgrading to a new type of storage medium, a driver storage element that can be mounted in the apparatus body is used. It is necessary to increase the number and a large space for it. Therefore, it is difficult to apply the present invention to a device such as a digital camera or a notebook personal computer using a recent IC card, which tends to have a smaller package.

As described above, the advantages of each of the recent storage media are various, but there is a problem that it is not possible to easily and inexpensively select a recording medium according to the application or situation. Further, when the performance or capacity of the recording medium is improved and its form is changed, it is difficult to quickly respond to the change, and there is also a problem that compatibility cannot be maintained depending on a device in which these are mounted as devices.

[0006] It is an object of the first invention according to the present application to cope with a plurality of storage media in a single device.

[0007] It is an object of a second invention according to the present application to cope with a change in a storage medium without changing a main body when a change is made to a recording medium.

[0008] It is an object of a third invention according to the present application to enable a storage medium to be changed in a small space of one device.

A fourth object of the present invention is to maintain compatibility with a storage medium so that one apparatus can access data of a storage medium recorded in another apparatus.

An object of a fifth invention according to the present application is to allow a driver to store a driver in a removable storage medium and load the driver into a driver storage element when a recording medium is changed.

An object of a sixth invention according to the present application is to enable a driver corresponding to a storage medium detachable from an apparatus main body to be loaded into a driver storage element when a recording medium is changed.

An object of a seventh invention according to the present application is to make it possible to reduce the number of slots in an apparatus main body to at least one.

An object of an eighth invention according to the present application is to facilitate determination of whether a removable storage medium attached to an apparatus is a medium that can be currently supported by the apparatus.

[0014] It is an object of a ninth invention according to the present application to facilitate determination of the content, use, and attributes of a removable storage medium attached to an apparatus.

An object of a tenth invention according to the present application is to reduce running costs and design and manufacturing costs of equipment including a data storage device.

[0016]

When no driver is included in the storage medium 7 (S
First, it is checked whether the status flag “exi_prot” is set (S815).

When "exi_prot" is on, the display LED 23 indicating the type of driver blinks (S816). After that, check if the status flag "sys_init" is set
(S817) Only when "sys_init" is not set, the system inside the digital camera is started and a start completion flag "sys_init" is set (S819). When the system has already been started or after the start is completed, the display LED 23 indicating the type of driver is turned on (S820), and it is confirmed whether the data storage medium 7 is the same as the type of driver (S821).
If the type is the same, set the status flag "drv-mtch"
If different (S823), a mismatch is displayed on the display panel 22 (S822).

If "exi_prot" is not set, the entire display LED 23 is turned on and off at a constant cycle (S825), and the power supply to both slots is cut off (S824).

In this mode, it is mainly used for system switching for changing the type of the recording medium 7 or when changing to another recording medium 7 of the same type as before.

Next, the operation in the case where the main mode switching sw is switched to the "reproduction / mode" (S305) will be described with reference to FIG.

First, if the status flag "exi_prot" is set, it is confirmed whether the driver is loaded in the driver storage element 2, and if the status flag "sys_init" is set, the completion of system startup is confirmed (S501, S50

Therefore, the reproduction is performed only when the driver is loaded into the driver storage element 2 of the adapter 1 and the start of the system is completed, the type of the storage medium 7 matches the driver, and the contents of the storage medium 7 are stored in the memory. Is included. If this condition is satisfied, confirm again that the main mode switch SW is "playback / mode" (S508).
After that, reproduction (S509) and search (S510) can be performed.

If any one of the status flags is not set, the entire display LED 23 is periodically blinked.
(S513) It is confirmed again that the main mode switching SW is “reproduction / mode” (S514). If the mode is not "playback / mode", search for the main mode switch SW (S
Return to (301), and in the case of "playback / mode", release SW
Is detected (S515), and only when the release switch is fully pressed (S516), the power is turned on again to both slots, and the detection of the inserted storage medium 7 (S404) is performed again.

In this mode, the recording medium 7 is mainly reproduced, and can be used for loading a driver or changing another recording medium 7 of the same type as before depending on the state of system startup.

Next, the operation when the main mode switching sw is switched to the "recording / mode" will be described with reference to FIG.

First, when the status flag "exi_prot" is set, it is confirmed whether the driver is loaded in the driver storage element 2, and when the status flag "sys_init" is set, the completion of the system startup is confirmed (S601, S60

Only when both the status flags are on, the power is turned on to both slots (S603), the index of the inserted storage medium 7 is read (S604), and the power to both slots is turned off (S605). ).

Thereafter, whether the storage medium 7 is of the same type as the driver (S606) or whether it is not a write-protected storage medium (S607),
It is determined from the read index information whether there is remaining memory capacity (S608), and the recording mode is entered again when the main mode switching sw is "recording / mode" (S609).

When the recording mode is entered, it is detected whether the release switch has been half-pressed (S610), and photometry, distance measurement, dimming and shooting preparation are performed (S611). Further, it is detected whether or not all the release switches have been pressed (S612), and only when the release switch is pressed, an image is taken and recorded (S61).
3, S614).

If any one of the status flags is not set, the entire display LED 23 is made to blink at a constant cycle (S617), and the process returns to the detection of the main mode switching SW (S301).

In this mode, this mode is mainly used for recording on the recording medium 7, and when the driver is not installed or the system is not in the activated state, or when the recording medium 7 and the write-protected storage medium of a different type from the driver are used. In the case of 7, the recording mode is not set.

The fourth embodiment is a second example of the above three methods of use, as shown in FIGS.
