(Example) Next, the present invention will be described in more detail with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a main part of a first embodiment of a recording device with a time signal recording function according to the present invention.

The clock circuit 1 consists of a semiconductor integrated circuit, and the output of the clock circuit 1 is divided into a time signal circuit 2 that counts the output and outputs a time information signal, and a time signal audio circuit that consists of a semiconductor integrated circuit that guides the time with synthesized voice. Connected to 3.

The time signal connection means includes a switch 11 which is a recording sound switching circuit that selects the output of the time signal generation means (time signal signal circuit 2 and time signal audio circuit 3) and connects it to the recording circuit, and a time signal transmission control that controls this switch 11. It consists of means.

The time signal transmission control means is composed of a time signal start signal transmission circuit 4, a timer 5, and a time recording control circuit 6.

The time signal start signal sending circuit 4 is a circuit that detects that the recorded sound during recording has stopped for a predetermined period of time or more, and sends out a start signal for inserting a time signal.

The timer 5 counts the time required to record the time signal.

The switch circuit 11 is a switch circuit that connects the outputs of the time signal circuit 2 and the audio circuit 3 to the recording circuit 13 during time signal transmission.

The time recording control circuit 6 is a time recording control circuit that sends a signal to the switch circuit 11 for connecting the outputs of the time signal signal circuit 2 and the time signal audio circuit 3 to the recording circuit 13.

The time signal output circuit 2 and the time signal audio circuit 3 form a time signal generating means for outputting time information, and the time signal start signal sending circuit 4, the timer 5, and the time recording circuit 6 form a time signal sending control means.

Note that the switch circuit 11 is another switch circuit 1.
2, these contacts can be switched manually or automatically by the output of the time recording control circuit 6.

The switch circuit 11 connects the output of the time signal generating means to the recording circuit 13 through its contact a1, and connects the output of the amplifier circuit 10 for normal recording to the recording circuit 13 through its contact b1.

The switch/2-inch circuit 12 opens and closes the output of the playback circuit 14 during recording and playback to a playback output section (not shown) through its contact C2.

Note that the contact a2 of the switch circuit 12 is connected to the switch circuit 11.
The contact b2 corresponds to the contact b1, and the switch circuit c1 corresponds to c2 of the switch circuit 12, and these are empty contacts.

Also, the microphone terminal 16. Auxiliary input terminal 17. The other terminal 18 is selected by the switch 15 and connected to the input of the amplifier circuit IO.

Next, the operation will be explained.

First, in the normal recording state, contact b1 of the switch circuit 11
The input from the microphone terminal 16 etc. is sent to the amplifier circuit 1 via
The audio output amplified by 0 is connected to the recording circuit 13 and recorded on a recording medium (not shown).

On the other hand, the clock circuit 1 continues to operate at all times even if the main power supply of the main body is cut off by a buffer sub-power supply (not shown).

The time signal signal circuit 2 generates and outputs a time signal sound based on the output of the clock circuit 1, and the time signal audio circuit 3 makes a time announcement such as "The current time is OO hour and minute" based on the output of the clock circuit 1. The contents of the time signal circuit 2 are determined, and the timing is set and outputted based on the output of the time signal circuit 2. The outputs of the time signal audio circuit 3 and the time signal signal circuit 2 are combined and applied to the contact a1 of the switch circuit 11.

Here, the time signal start signal sending circuit 4 determines the recording end point from the general recording content sent to the time signal start signal sending circuit 4 through the route shown by the dotted line arrow in the diagram for part of the output of the amplifier circuit 10. It detects the signal and sends a time signal start signal to the timer 5 and the time recording control circuit 6.

Upon receiving the time signal start signal, the time recording control circuit 6 sends a switching signal to the switch circuit 11 to connect the recording circuit 13 to the contact a] as indicated by the dotted arrow in the figure.

The timer 5 starts counting time upon receiving the time signal start signal, and after a predetermined time has elapsed, sends a counting end signal to the time recording control circuit 6. In response to this, the time recording control circuit 6 activates the switch 11. A switching signal is sent to connect the recording circuit 13 to the contact b1 as shown by the solid arrow in the figure.

Next, the end of recording in the time signal start signal sending circuit 4 is determined based on whether or not a predetermined time has elapsed with the level of the input audio signal being below a predetermined level. , an example of a flowchart of the operation of this embodiment is shown in FIG.

First, when the apparatus of this embodiment is started in step 20, the function switching state is determined in the next step 21, and if the recording state is selected, a recording operation is performed in step 22.

In step 23, it is determined whether or not the recording has ended, and if the recording has not ended, the recording in step 22 is continued.

If the recording has ended, a recording end signal is sent to the time signal start signal sending circuit 4 in step 24, and time recording is performed. Once the time recording is complete, step 2
Returning to step 1, determining the function switching state.

Note that if the function switching state is the recording/playback state in step 21, the recording/playback in step 25 is performed, and if the function switching state is in the stopped state, the process settles to stop in step 26.

In addition, in the explanation of Figures 1 and 2, the time recording in which the time signal is inserted is performed immediately after the end of the general audio, but it may be inserted at another location. You can.

Further, although the time signal is composed of a time signal sound following a time signal announcement, it may also be recorded with a combination of a simple code tone 1, for example, a short pulse, or a multi-frequency signal such as that used for push button dialing. In this case, since it only takes a short time, it is unlikely to interfere with normal recording and playback of other recordings. However, a special additional circuit is required on the recording/playback side to decode the contents of the 9 o'clock signal.

Furthermore, a push button or the like may be provided for manually switching the switch 11 from contact b1 to al in order to insert a time signal at an arbitrary time.
