FIG. 1 is a block diagram showing an embodiment of the present invention.
Will be described in detail. In FIG. 1, reference numeral 1 denotes a storage device, and the storage device 1 is provided with a CPU 2 for controlling the whole. Further, the storage device 1 is provided with a reader unit 4 integrated with the memory card socket 3. When the memory card 5 is stored in the memory card socket 3, the reader unit 4 The digital data such as the photographing data of the digital camera 6 recorded on the card 5 is read. The memory card socket 3 is configured so that the memory card 5 can be freely attached and detached by a detent mechanism or the like.

The output of the reader unit 4 is connected to a changeover switch 7. When the switch 7 is switched upward in the figure, the digital data of the memory card 5 read by the reader unit 4 is subjected to intermediate processing via the I / F unit 8 and then to another switch 9. When the changeover switch 9 is connected in the horizontal direction in the figure, the digital data is subjected to a parity check or the like by the data processing unit 10 via the changeover switch 9 and then modulated by the modulation unit 11. After the power control for recording is performed by the PW control unit 12, the digital data is written to the CD-R 14 by the pickup unit 13 and recorded and stored. Thus, the risk of storing digital data only in the expensive memory card 5 is eliminated, and the convenience of the digital camera 6 using the memory card 5 as a storage medium is improved.

On the other hand, when the switch 7 is switched downward in the figure, the digital data of the memory card 5 read by the reader section 4 reaches another switch 16 via the I / F section 15. When the changeover switch 16 is tilted rightward in the figure, the digital data is sent to the digital input / output terminal 17 of the storage device 1 via the changeover switch 16. Then, the desktop personal computer 1 is connected via the cable 18 connected to the digital input / output terminal 17.
9 is output. This enables the desktop PC 1
Even if the card slot 9 is not provided, the data captured by the digital camera 6 recorded on the memory card 5 can be loaded into the desktop personal computer 19 and edited or printed.

When the digital data written on the CD-R 14 is read by the pickup unit 13 after the changeover switch 16 is tilted to the left in the figure, the digital data is demodulated by the demodulation unit 20, After the data processing unit 21 performs processing such as removal of the parity code, the data is buffered by the memory control unit 22. The signal is finally converted by the I / F unit 23 for the cable 18, sent to the digital input / output terminal 17 via the changeover switch 16, and output to the desktop personal computer 19 via the cable 18. Thus, the CD-R1
4 is taken into the desktop personal computer 19 and reproduced.

Further, after the changeover switch 9 is tilted downward in the figure and the changeover switch 16 is tilted to the left in the figure, digital data in the desktop personal computer 19 is output to the storage device 1 via the cable 18. Then, the digital data is sequentially transferred to the changeover switch 16, the I / F unit 23,
Memory control unit 22, changeover switch 9, data processing unit 1
0, the data are written to the CD-R 14 by the pickup unit 13 via the modulation unit 11 and the PW control unit 12. Therefore, in this case, the storage device 1 is the desktop personal computer 1
9 functions as an external auxiliary storage device.

The wiring connecting the changeover switch 16 and the digital input / output terminal 17 branches in the middle, and the branch path 2
4 is provided with an on / off switch 25 and an encoder 26, and a video output terminal 27 is provided at the end thereof. A television receiver 29 is connected to the video output terminal 27 via a cable 28. Therefore, the changeover switch 16 is tilted to the left and the on / off switch 2
5 is closed, the digital data stored in the CD-R 14 is converted to a video signal by the encoder 26 instead of being reproduced on the display of the desktop personal computer 19 and reproduced on the television receiver 29. Can be.

In this case, the CD-R is used as the memory unit. However, the present invention is not limited to this, and a magnetic disk such as a floppy disk or a magneto-optical disk such as a mini disk may be used.

Thus, the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones.

[0017]

As described above, according to the present invention, digital data such as image data taken by a digital camera can be recorded and stored not only on an expensive memory card but also on a relatively inexpensive CD-R or the like. This eliminates the risk of storing data only in a memory card.

Further, even a desktop personal computer without a card slot can easily take in data recorded on a memory card, and can be generally used as an external auxiliary storage device of a personal computer or the like.

Thus, the convenience of a digital camera, a desktop personal computer, and the like is improved.
