It can be set appropriately depending on the situation. For example, if the internal slot A is provided for data storage, the internal slot B is inserted when the storage medium is inserted. It can also be configured to switch the active slot from the slot A to the internal slot B.
• the priority of the external slot is set lower than that of the internal slot. For example, the digital still camera is connected via the external storage device connection port 22.

• Priorities are assigned to the ports obtained, and, for example, when a storage medium is inserted in each of a plurality of external storage devices, an effective slot is determined according to the priorities. Switching of the effective slot between the external storage devices is performed when the storage medium is removed from the enabled external storage device, as in the case of the internal slots. The active slot is switched to another storage device in which is inserted.
• the valid slot if a certain slot is valid, the valid slot is inserted even if the storage medium is inserted into another slot. Until the storage medium is removed from the slot, the newly inserted slot is not switched over to the active slot. In such a case, the effective slot may not match the slot intended by the user. Therefore, when a slot is valid and a storage medium is inserted into another slot, a predetermined message as shown in Fig. 10 (C) is set. It is desirable to display it on screen 10. The user can confirm the message on the screen and remove the storage medium from the current valid slot, thereby making the intended slot the valid slot. Become so.

According to this, since it is possible to access only the storage medium to which the access right is given, it is also possible to limit the number of storage media that can be simultaneously accessed at the time of direct printing to one. it can. Specifically, when the storage medium is mounted on a plurality of slots, the exclusive control unit 35 assigns the access right only to the storage medium mounted on one slot. I do. Only the storage medium to which the access right has been granted can receive an access request from a predetermined request source.

Further, the exclusive control unit 35 can appropriately set the content of the access right given to the storage medium. For example, the access right consists of the right to receive data read access and the right to receive data write access, and grants each right to different storage media. You can do that too.
