The above-mentioned conventional audio recording system employs magnetic recording and special optical recording systems, so it requires a special device to copy information to other media, and has the disadvantage that it cannot be easily copied. Also, if you want to send the recorded contents to a remote location,
Direct transmission using an analog signal will cause deterioration in the analog signal transmission path, resulting in a loss of digital transmission.
There is a disadvantage in that the equipment becomes expensive if the recording medium is sent as it is.1 Furthermore, if the recording medium is sent as it is, it requires a lot of manpower and time.

Next, the reading scanner mechanism 15 is activated to read digital data from plain paper recorded in facsimile format, and temporarily store it in the external storage device 29 (S41.S
42,543). Note that 842° and 343 are respectively the above-mentioned S21. This is the same process as S22, and is also the process step S46 when there is no empty space in the two external storage devices in S42. S47 is the above-mentioned 825. This is the same as S26. The central processing unit 27 checks whether the input manuscript is finished (544), and starts the audio output process after finishing reading all the input manuscripts (S45). Note that if the input manuscript is not completed in S44, a message to that effect is displayed (S48).
). That is, the central processing unit 27 reads the digitized audio information from the two external storage devices and sends it to the digital-speech conversion circuit 19 via the digital-speech conversion control circuit 20 (S 5 ). The digital/audio conversion circuit 1 (-) converts this digital audio information into analog audio 1-7 and sends it to an audio reproduction mechanism (not shown) (S52>.
