Abstract: A voice recorder pen includes a body including a power supply and a PCB and a pen tip portion coupled to one end of the body. The body includes a power supply and a PCB. The power supply includes a battery to supply power to the PCB. The PCB includes thereon a microphone for voice detection, a record on/off switch for turning a record function on/off, a microcomputer/memory unit for amplifying and converting voice detected by the microphone into a digital signal and storing the digital signal, and a connection portion adapted to be connected to an external operating unit. An operating clip is provided on an outer surface of the body. The operating clip is coupled to the record on/off switch to operate the record on/off switch. Accordingly, the configuration of the body is simplified, increasing the convenience of the use of the voice recorder pen, while reducing the body size.
