Embodiment Construction

[0025] Referring to the accompanying drawings, the following is a description of an embodiment of the present invention. The same designation is used for Figure 9 The same or similar parts of the conventional apparatus shown in .

[0026] figure 1 is a block diagram showing the basic construction of an audio recording device (1) according to the invention. A microphone (11) is a sound collecting device which collects audio to be stored and converts it into an analog electrical signal. The analog electrical signal is amplified by an amplifier (12) and digitized by an A / D (analog / digital) converter (13). A DSP (Digital Signal Processor) (14) performs compression and other processing on the digital audio signal which is the input from the A / D converter (13).

[0027]The audio recording device (1) of this embodiment is provided with an IC memory (15) as a recording medium for storing audio data. The IC memory (15) may be in the form of a card and shaped such that it can be f...

Abstract

An audio recording device is provided with a first casing, which includes a sound collection means, a second casing, which includes a terminal for connection to an external device. One end portion of the second casing is rotatably joined to a lower end portion of the first casing, such that the second casing can be folded and stored on a rear side of the first casing; the sound collection means is provided at an upper portion of the first casing; and the connection terminal is protrudingly provided on another end portion of the second casing. Furthermore, a recessed portion, into which the connection terminal is fitted, may be formed at a raised portion on the rear side of the first casing, and a front end portion of the connection terminal may be covered by a wall of the recessed portion when the second casing is in a folded and stored state.

Description

technical field [0001] The present invention relates to an audio recording device for storing audio data in an IC (Integrated Circuit) memory or other type of recording medium, and more particularly to an audio recording device capable of transferring audio data to and from an external device audio recording device. Background technique [0002] In recent years, it has become common to convert an analog audio signal obtained through a microphone or other sound collecting device into digital audio data and store the digital audio data in an IC memory. This type of audio recording device does not require a rotary drive mechanism, and thus has the advantage of being lightweight and compact when compared with an audio recording device using a magnetic tape or a magneto-optical disk as a recording medium. [0003] There are some audio recording devices using an IC memory as a recording medium, the above-mentioned audio recording devices can be connected to a personal computer (h...
