The operation of the present invention made as described above will be described with reference to FIGS. 2 and 3A to 3H.

First, power the recorder at the site where the shorthand is to be performed, and then the unit starts to control.

Therefore, the controller 17 performs an initialization operation of clearing the flag Flag of each command processor to 0 and clearing the register (S1).

Then, the signal applied from the key switch 20 is read (S2) to determine whether or not the key input is input (S3).

If it is determined in S3 that there is no key input, the states of the rewind flag and the fast-forward flag are judged (S101, S103). If it is 1, the flag is cleared to 0 (S102, S104), and the current mode state is read (S105). The recognition is judged (S106). If it is determined that the playback state is determined, a command according to the mode is processed (S107), and if it is not in the playback state, the process returns to S2.

If it is determined in S3 that there is a key input, it is judged whether or not the recording key is selected (S4). If the recording key is selected, the recording flag is set to 1 (S5) and processed according to the recording command (S6).

Therefore, the voice signals input through the microphones 111 and 119 are digitally converted and compressed, and are sequentially stored in the memory for each group to perform recording.

While the recording function is being performed, the playback mode and other key inputs are checked (S7). If there is no key input, the recording function is continued. If there is a key input, the recording stop key is selected (S8) to stop recording. If the key is selected, the recording flag is cleared to 0 to stop recording (S9), and then a recording release processing command is executed (S10).

However, if the recording stop key is not selected in S8, another function key is selected. Therefore, it is determined whether to select another function key.

The function key selection determination step includes the step of comparing the selection of the low speed playback key selection (S11), the step of comparing the determination of whether the high speed playback key selection (S12), and the step of comparing the determination of the normal speed playback key selection (S13), comparing and determining the fast forward key selection (S14), comparing and determining the rewind key selection (S15), comparing and determining the playback key selection five seconds ago (S16), Comparing and determining whether to select the playback stop key (S17).

The recording function is continued unless the recording stop function is selected when each of the various function keys is selected.

If the low speed playback key is selected among the various function keys, it is determined whether or not the current low speed state is present (S201). If the low speed state is not the lowest speed state, the low speed mode which is the next step of the lowest speed is selected (S202) to process a command according to the mode. (S203). However, if it is determined as the lowest speed state to process the current mode (S203).

If the high speed playback key is selected, a comparison is made to determine whether the current highest speed state is present (S301). If the high speed playback key is not selected, the high speed mode which is the next step of the highest speed is selected (S302), and a command according to the mode is processed (S303). However, if it is determined that the fastest state is to process the current mode immediately (S303).

If the function key is selected as the normal speed regeneration key, it is set to 1: 1 normal speed mode (S401), and the command is processed in the set mode (S402).

If the fast-forward key is selected, compare the fast-forward flag (FF FLAG) to 1 before executing the current fast-forward mode (S501). If not, set FF FLAG to 1 and set the rewind flag (RW FLAG) to 0. Clear (S502). After adjusting the flag value, the current mode is stored in the memory (S503), the comparison is judged whether it is in the playing state (S504), and if it is not in the playing state, the position is moved forward (S507). The mode is set (S505) and the command is processed according to the set mode (S506). If it is determined in step S501 that FF FLAG is 1, execution proceeds to step S504.

If the rewind key is selected, before executing the current rewind mode, the rewind flag RW FLAG is determined to be 1 (S601). If not, the RW FLAG is set to 1 and the FF FLAG is cleared to 0 (S602). After adjusting the flag value, the current mode is stored in the memory (S603), and a command is processed according to the stored mode (S604). If it is determined in step S601 that the RW FLAG is 1, a command for immediately moving the position back is performed (S604).

If the key to be played back 5 seconds ago is selected, a comparison is made to determine whether it is currently playing (S701), if it is being played, the position of 5 seconds ago is calculated (S702), and the command is moved to the calculated position (S703), and a command according to the mode is processed. (S704). However, if it is not playing back in S701, the process returns to the step S2 of reading the key switch.

If the playback stop key is selected, the FF FLAG and RW FLAG are cleared to perform the playback stop function (S801), and set to the stop mode (S802) to cancel playback (S803).

According to the configuration and operation described above, when the registrar selects the playback key at the same time as the recording, the recording function is performed by performing S4 to S6, and the low speed playback is performed by performing the S11 and S201 to S203 if the playback speed is low. do.

In such a case, if the registrar selects the key to be returned to 5 seconds ago, it can be played back by returning to the desired portion by S16 and S701 to S704.

At this time, the part set to 5 seconds ago can be set to the most appropriate time through the test.

In addition, the function to return to the 5 seconds ago can be used by the user several times, so it is easy to return to the desired part.

In this state, in order to stop the recording function, the recording function can be stopped by S8 to S10.

While recording is in progress, the state of key input is always checked by S7, so it is possible to perform various functions such as playing, fast forwarding, and rewinding at multiple speeds.

In this case, the display unit 16 displays a sign indicating the speaker currently speaking to distinguish which person's words and the total recording time and the current playback time are displayed to check the shorthand time of the registrar for the currently recorded time. can do.

As described above, the present invention can record and play back the voice spoken by the speaker at the time of shorthand input, and play back the data for the voice that has not been processed since the shorthand can be selected in various modes. The speed can be controlled slowly to increase the accuracy of shorthand, and can be recorded and played back at the same time because the effect can be received quickly because it is a very useful invention in the field of shorthand and the recorder manufacturing industry.
