If the microcontroller unit 4 p Before deleting the image file, it was detected that this file was previously set by the user to be retained in the internal memory 3. At this time, the microcontroller unit 40 will drive the buzzer 80 to issue a warning sound, and The liquid crystal display 6 outputs the image file screen for the user to determine whether to delete the image file from the internal memory 3, so as to prevent accidentally deleting the image file to be retained. FIG. 2B is a schematic diagram showing the appearance of the digital camera 100 and the external memory card 7 used in the digital camera 100 and the combined use of the digital camera 100, as shown in FIG. 2B. It is shown that the slot module 70 set by the data transmission management device of the present invention includes a guide slot 71 and a clip structure 72 (Note: One point to note here is that Figures 2A and 2B are simplified The schematic diagram is only to illustrate the basic idea of the present invention in a schematic manner, so the elements shown therein are not drawn with the number, shape, and size ratio in actual implementation). Both the slot module 70 and the guide slot 71 are fixedly arranged inside the body of the card-type digital camera 100; as shown in the figure, since the length of the guide slot 71 is only equal to the data storage module A specific fractional ratio of the length of the group is, for example, 1/5 or 1/6. In principle, the smaller the length of the guide groove 71, the better; but the principle is to make the external memory card 7 stable in positioning, as shown in Figure 2B. In actual application, the user can place the external memory card 7 The card-type digital camera 1 0 0 is inserted into the guide slot 7 1 until the electrical connection point 7 3 on the external memory card 7 contacts the electrical connection point 7 4 on the slot module. At this time, the clamping structure 72 can apply a clamping force to the external memory card 7 to record the external memory card 7.

Description of the invention (11) A warning sound is issued to remind the user that the storage space of the internal memory 3 is full, and an external memory card 7 needs to be inserted to continuously complete the dictation work of the image file, and then proceed to step S4. In step S4, the microcontroller unit 40 uses the digital signal processing unit 20 to detect whether the external memory card 7 is inserted into the slot module 70 through the slot module 70. If the external memory card 7 has been inserted into the slot module 70, then proceed to step S5. If the external memory card 7 has not been inserted into the slot module 70, return to step S3, and continue to issue the storage space of the internal memory 3 full. A warning message. In step S5, the microcontroller unit 40 drives the liquid crystal display 6 to output a screen C through the display driving module 50 to notify the user that the external memory card 7 has been correctly inserted into the slot module 70, and then The microcontroller unit 40 reads the influence files stored in the internal memory 3 through the digital signal processing unit 20, and transfers the image files to the external memory card through the slot module 70 as a data transmission interface. 7 and then proceed to step S6.
