  Thereby, when the terminal of the other device different from the earphone device 3 is mistakenly connected to any one or two of the connection terminals 61 to 63, the CPU of the earphone mounting unit 59 is connected to the power of the other device. It is possible to prevent failure due to supply.

  In addition to this, the mounting unit housing 60 (FIGS. 5 to 7) has, for example, one operation button 75 disposed at the center on the bottom surface 60EX of the housing holding unit 60E, and 2 closer to the other end of the mounting unit. Two operation buttons 76 and 77 are arranged.

  Incidentally, the operation button 75 disposed at the center of the bottom surface 60EX of the housing holding part 60E is for inputting, for example, a playback start or pause command for audio data in a toggle manner.

  Further, one operation button 76 disposed near the other end of the mounting portion of the bottom surface 60EX of the housing holding portion 60E can, for example, issue a fast-forward playback for audio data or a command for switching playback to the next audio data at a pressing time. It is for inputting according to the difference.

  Further, the other operation button 77 arranged near the other end of the mounting portion of the bottom surface 60EX of the housing holding portion 60E can, for example, issue a command for fast-rewind playback with respect to audio data or playback switching to the previous audio data. It is for inputting according to the difference.

  Actually, a switch element 78 such as a diaphragm is mounted on one surface of the circuit board 70 (FIG. 10) in the board storage chamber 60H so as to face the operation buttons 75 to 77.

  Then, when the operation buttons 75 to 77 are pressed by the CPU of the earphone mounting portion 59 in a state where the earphone device 3 is not mounted (that is, the bottom surface 60EX of the housing holding portion 60E is opened). The pressing operation is detected via the corresponding switch element 78.

  In addition, the CPU of the earphone wearing unit 59 notifies the CPU in the portable playback device 2 of the detection result of the pressing operation by the switch element 78 via the external terminals 71 and 72 sequentially.

  As a result, the CPU in the portable playback device 2 detects the command input via the operation buttons 75 to 77 of the earphone mounting unit 59 based on the detection result notified from the earphone mounting unit 59, and detects the detected command. Performs processing according to the instruction.

  In this manner, the earphone mounting unit 59 can input various commands via the operation buttons 75 to 77 in the housing holding unit 60 when the earphone device 3 is not mounted.

  By the way, in the mounting portion housing 60 (FIGS. 5 to 7 and 10), a stepped portion 60EM having a rectangular shape that is one step higher than the bottom surface 60EX is formed at the central portion of the mounting portion one end side of the bottom surface 60EX of the housing holding portion 60E. Has been.

  Further, in the mounting portion housing 60, a belt-like stepped portion 60EN that is one step higher than the bottom surface 60EX is formed in parallel to the mounting portion width direction on the other end of the mounting portion of the bottom surface 60EX of the housing holding portion 60E.

  Further, each of the step portions 60EM and 60EN has a height from the bottom surface 60EX of the housing holding portion 60E to the flat top surface of the step portions 60EM and 60EN from the bottom surface 60E to the operation buttons 75 to 77 arranged on the buttons. Is selected to be slightly higher than the height up to the top surface.

  Then, when the earphone device 3 is mounted, the mounting unit casing 60 contacts one end of the right casing with the upper surface of one stepped part 60EM in the right casing rear surface 30F of the right casing 30 held in the casing holding unit 60E. At the same time, the other end of the right casing is brought into contact with the upper surface of the other stepped portion 60EN.

  In addition, when the earphone device 3 is mounted, the mounting unit casing 60 has one end of the left casing that touches the upper surface of one stepped part 60EM in the left casing rear surface 31F of the left casing 31 held in the casing holding unit 60E. In addition, the other end side of the left casing is brought into contact with the upper surface of the other stepped portion 60EN.

  Therefore, when the earphone device 3 is mounted, the mounting unit housing 60 is operated by the operation buttons 75 by the right housing back surface 30F and the left housing back surface 31F of the right housing 30 and the left housing 31 held in the housing holding unit 60E. To 77 (that is, erroneous operation) can be prevented.

  By the way, the portable playback device 2 is provided with the above-described hold switch 19 so as to be slidable to one end side and the other end side of a predetermined slide range, for example, along the longitudinal direction of the device.

  Then, for example, when the hold switch 19 is slid to one end of the slide range, the portable playback device 2 performs various operation buttons 12 to 14 on the device front surface 10E, the volume adjustment button 17 on the device side surface 10C, and the wireless The operation with the communication button 18 is invalidated.

  In addition, for example, when the hold switch 19 is slid to the other end side of the slide range, the portable playback device 2 has various operation buttons 12 to 14 on the front 10E of the device, a volume adjustment button 17 on the side 10C of the device, The operation with the wireless communication button 18 is validated.

  As a result, the portable playback device 2 can be configured such that, for example, when the hold switch 19 is slid to one end of the slide range while being placed in the bag, the various operation buttons 12 to 14 and the like are set in the bag. If it is accidentally pressed by another object, it can be ignored.

  That is, even if the various operation buttons 12 to 14 and the like are accidentally pressed with other objects in the bag as described above, the portable playback device 2 executes unnecessary processing against the user's will at that time. It is avoiding that.

  However, the portable playback device 2 invalidates the operation by the hold switch 19 with respect to the various operation buttons 12 to 14 on the front 10E of the device and the volume adjustment button 17 and the wireless communication button 18 on the side 10C of the device. Only applied.

  That is, although the portable playback device 2 is configured to accept the operation of each operation button 75 to 77 of the earphone attachment unit 59, the invalidation of the operation by the hold switch 19 is disabled. Is not applied.

  For this reason, when the earphone device 3 is mounted, the earphone mounting unit 59 closes the casing holding unit 60E with the right casing 30 and the left casing 31 to hide the operation buttons 75 to 77 from the outside.

  Accordingly, the earphone mounting unit 59 can reliably avoid erroneous operation of the operation buttons 75 to 77 when the earphone device 3 is mounted when the portable playback device 2 is not used, for example. it can.

  On the other hand, the earphone mounting unit 59 exposes the operation buttons 75 to 77 in the housing holding unit 60E to the outside while the earphone device 3 is being used together with the portable playback device 2.

  However, the mounting portion housing 60 has a thick edge (that is, higher than the bottom surface 60EX of the housing holding portion 60E) around the housing holding portion 60E (that is, a width one-direction edge 60A, a width other-direction edge). 60B, one end side edge portion 60C, and the other end side edge portion 60D).

  Therefore, the earphone mounting portion 59 is configured so that, for example, even if the portable playback device 2 used with the earphone device 3 is put in a bag, the operation buttons 75 to 77 can be made difficult to be pushed by other objects in the cage.

  In addition, the mounting portion housing 60 is selected so that the one-side edge 60A in the width direction, the other-direction edge portion 60B, and the one-end side edge portion 60C are substantially equal among the peripheral edges of the housing holding portion 60E. However, only the height of the other end side edge portion 60D is selected to be higher than the other portions.

  Thereby, when the portable playback device 2 used with the earphone device 3 is placed in the bag, for example, when the hand is put in the bag and the edge is touched, The other end side edge portion 60D can be easily distinguished from other portions.

  Therefore, at this time, the earphone mounting portion 59 does not bother to take out the portable playback device 2 from the bag, but puts the hand into the bag and uses the position of the other end side edge 60D as a clue. The operation buttons 75 to 77 can be easily distinguished and operated.
