Description

Business Diary Note with Digital Voice Recorder

The present invention relates to a work diary notebook with a built-in digital recording device. More specifically, a small digital recording device is built into the diary so that a voice recorder can record a voice content or a voice memo of a mobile phone without the conversation partner's recognition. It is about diary notebook to say.

In general, a portable digital recording device can be used in a public or permitted place without discomfort to the other party, but a small pin microphone may not be used or visible during meetings or during conversation for information gathering. Often hidden and used in places to make the other person unconscious. In addition, in the previous work diary notebook, it was inconvenient to record all important contents during a meeting or a conversation by writing only with writing instruments.

The purpose of the present invention is to use a portable work diary notebook for recording business meetings or conversations, in addition to recording using writing tools, separate digital recording for recording by using a diary notebook with a built-in digital recording device. It can reduce the inconvenience of carrying the device, reduce the discomfort that the recording device can be exposed to the other party during use, and at the same time play back and check the meeting and conversation contents stored in the digital recording device to check the recorded contents. It is to provide a digital recorder diary notebook that helps the user not to be missed.

According to the present invention, as shown in Figures 2 and 3, the microphone (1) receiving the analog sound signal, the signal processing unit (2) for amplifying and converting and converting the input analog sound signal into a digital signal, A memory unit 3 storing data, a switch control unit 4 for selecting or adjusting a sound signal recording, playback, deletion, volume, etc., and an LCD display unit 5 indicating a current operation state and a residual power state, etc. And a digital recording device in which a speaker unit 6 and an earphone unit 7 for outputting and listening to the recorded contents, and a power unit 8 for supplying power for driving the entire apparatus are combined. A portable work diary notebook is provided.

Hereinafter, described with reference to the accompanying drawings, preferred embodiments of the present invention is as follows.

FIG. 2 illustrates a business diary notebook in which the digital recording device 11 according to the present invention is incorporated. The digital diary in the form of a PC as shown in FIG. 3 is formed in the front outer shell or the rear outer shell of the diary notebook. A recording device is mounted, and as shown in FIG. 3, a switch for operating a digital recording device such as a play and stop, rewind and fast play, a record and stop, a delete switch, and a volume switch for adjusting the playback volume is provided by the user. Make sure to be exposed to the surface of the diary notebook for easy operation.

The built-in speaker, which allows you to listen to the recording during playback, is concealed in the diary envelope, and a small sound hole is drilled in the envelope to make the playback easier to hear. In addition, when listening to the playback content using an earphone, etc., connect the earphone to the earphone jack connected to the PCB (PCB) is used.

The recording microphone uses a small microphone and is mounted on the top of the diary notebook so that the microphone surface is perpendicular to the notebook surface for recording. Even in this case, a small air hole is drilled in the shell so that the acoustic signal is well received.

An LCD display device that displays the operation status of the digital recording device and the remaining battery power is mounted on the upper part of the operation switch for better visibility.

Batteries supplying the power required for operation can be mounted in the case of ordinary cylindrical batteries with a space at the edge of the diary shell, and in the case of using a thin-film square battery, it can be mounted in a position where the diary shell is not thick.

And the operation switch is produced in a form appropriately recessed inwardly on the diary envelope 22, as shown in Figure 4 so as to prevent a malfunction due to the pressing while recording on the recording paper in the diary notebook, as shown in Figure 4 In order to prevent the diary notebook from being bent and broken, the PCB 33 of the digital recording device built in the diary notebook is preferably made of a material having high strength.

As described above, according to the present invention, by using the digital recording device embedded in the portable work diary notebook, it is possible to reduce the inconvenience of carrying the diary notebook and the digital recording device, respectively, and to record the conversation naturally without being exposed to the other party. It can reduce the discomfort that the other party is recording, and can check the contents of meetings and conversations stored in the digital recording device by playing them when necessary, and check the desired contents without missing them. There is an effect that can exhibit both the recording function and the playback function of the digital recording device. In addition, since the work diary notebook can be used only after each year of use of the recording paper, the digital recording device and the diary notebook envelope can be used permanently.
