Description

  The present invention relates to a command input device, and is suitable for application to a recording / reproducing system having a portable recording / reproducing device, for example.

  The conventional playback device has a play key and a stop key. When the play key is operated while music playback is stopped, the operation state is switched to music playback, and when the play key is operated during music playback. When the elapsed time from the start of the operation to the end of the operation is shorter than the predetermined time, the operation state is switched to pause, and when the elapsed time is longer than the predetermined time, the operation state is switched to fast forward (or high speed reproduction).

In addition, when the stop key is operated during music playback, the playback device switches the operation state to stop when the elapsed time from the start of the operation to the end of the operation is shorter than the predetermined time, and the elapsed time is less than the predetermined time. If it is too long, the operation state is switched to fast forward (or high speed reproduction) in the reverse direction (see, for example, Patent Document 1).
JP-A-8-329587 (2nd page, 3rd page, FIG. 2, FIG. 3)

  By the way, in the reproduction apparatus having such a configuration, two types of operation keys (that is, the reproduction key and the stop key) are provided in accordance with whether the elapsed time from the operation start to the operation end is longer or shorter than a predetermined time. An instruction is assigned.

  However, in the reproducing apparatus having such a configuration, when the types of instructions that can be input are increased, the operation keys to which two types of instructions are assigned are increased, and as a result, the operation for the operation keys for inputting individual instructions is started. There is a problem that it is difficult to improve the operability because it is necessary to use a plurality of operation keys in consideration of both the elapsed time from the operation to the end of the operation and to which operation key the command is assigned.

  The present invention has been made in consideration of the above points, and an object of the present invention is to propose an instruction input device capable of remarkably improving the operability at the time of inputting an instruction.

  In order to solve such a problem, in the present invention, an operation is performed by sequentially switching between an instruction reception state in which an instruction is received at an arbitrarily selected duration and an acceptance release state in which the instruction reception state is temporarily canceled. The command accepting state for the operating element is determined from among at least two types of command accepting states distinguished by the difference in duration, and the accepting canceling state for the manipulator is continued for a predetermined end judgment reference time or more. When the operation on the operator is determined to be completed, the operation according to the operation on the operator is determined based on the combination of the two types of command reception states determined from the start to the end of the operation on the operator. The command entered was identified.

  Therefore, without making any consciousness about which operator is assigned to each of the many commands, only one combination of at least two types of command reception states is made to be recognized by one operator. It can be input easily.

  As described above, according to the present invention, an operation is performed by sequentially switching between an instruction acceptance state in which an instruction is received at an arbitrarily selected duration and an acceptance release state in which the instruction acceptance state is temporarily canceled. It is determined whether the command reception state for the operation element is one of at least two types of command reception states distinguished by the difference in duration, and the reception cancellation state for the operation element is continued for a predetermined end determination reference time or more. At the time, it is determined that the operation with respect to the operation element has ended, and based on the combination content of the two types of command reception states determined from the start time to the end time of the operation with respect to the operation element. By identifying the input instruction, one instruction can be used without being aware of which operator each of the instructions is assigned to. By using an operator, it is possible to easily input a large number of commands just by considering only a combination of at least two types of command reception states, thus realizing a command input device that can greatly improve the operability during command input. can do.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes a recording / reproducing system to which the present invention is applied as a whole, and a personal computer 4 can be connected to a portable recording / reproducing apparatus 2 via a predetermined cable 3 such as a USB (Universal Serial Bus) cable. An earphone with a remote controller (hereinafter referred to as an earphone with a remote controller) 5 can be connected to the portable recording / reproducing apparatus 2.

  In this case, when the personal computer 4 is connected to the portable recording / reproducing apparatus 2 via the cable 3, the personal computer 4 can control recording / reproducing of music data with respect to the portable recording / reproducing apparatus 2.

  Therefore, the portable recording / reproducing apparatus 2 is, for example, a Mini Disc (registered trademark of Sony Corporation) that is detachably loaded when music data is transmitted together with a recording command from the personal computer 4 via the cable 3. The music data is recorded on the magneto-optical disk according to the recording command.

  Also, when a playback command is transmitted from the personal computer 4 via the cable 3, the portable recording / playback apparatus 2 plays music data from the magneto-optical disk according to the playback command, and the played music data is sent to the cable 3 via the cable 3. By transmitting to the personal computer 4 via the computer, music based on the music data can be output from the speaker of the personal computer 4 so that the user can listen to it.

  On the other hand, in the earphone 5 with a remote controller, a cylindrical remote controller housing (hereinafter referred to as a remote controller housing) 6Z is connected to a pin connector 6X inserted into the portable recording / reproducing apparatus 2 via a cable 6Y. An earphone unit formed by connecting the earphone 7Y to the pin connector 7X inserted and attached to the remote controller housing 6Y via the cable 7Y. 7.

  The remote control housing 6Y is provided with a single operation element 8 that can be pressed at one end, and a display unit that displays various information such as the playback state of music data of the portable recording / playback device 2 on the side surface ( This is hereinafter referred to as a remote control display unit) 9.

  Then, when the earphone 5 with a remote control is connected instead of the personal computer 4, the portable recording / reproducing apparatus 2 can input a large number of commands by changing the content of the pressing operation on the operator 8 of the earphone 5 with the remote control. When, for example, a playback command is input in response to the pressing operation, music data is played from the magneto-optical disk according to the playback command, and music based on the played music data is transmitted via the earphone 7Y. It can be output and listened to by the user.

Here, in practice, the personal computer 4, as shown in FIG. 2, is a RAM (Random) used as a work area of the CPU 20 via a bus 21 to a CPU (Central Processing Unit) 20.

  Then, the CPU 20 develops various programs read from the hard disk of the hard disk drive 23 in accordance with various commands input via the operation unit 24 on the RAM 22, thereby comprehensively controlling each circuit unit according to the developed various programs. Various processes can be executed under control.

  That is, during the acquisition process of the music data D1, the CPU 20 displays a predetermined acquisition process screen on the display unit 25, and in this state, an acquisition command is input on the acquisition process screen according to the operation of the operation unit 24 (for example, a mouse). In response to this, desired music data D1 is acquired from a server on the network via the network interface unit 27, and the acquired music data D1 is grouped in units of albums of a desired category or a desired artist, for example. To be recorded on the hard disk of the hard disk drive 23.

  Further, the CPU 20 displays a predetermined recording control screen on the display unit 25 during recording control of the music data D1 with respect to the portable recording / reproducing apparatus 2 (hereinafter referred to as data recording control).

  In this state, the CPU 20 designates the music data D1 to be recorded for the portable recording / reproducing apparatus 2 on the recording control screen in accordance with the operation of the operation unit 24 (for example, a mouse) and inputs a recording start command, for example. Then, one or more music data D1 in a specified group unit is read from the hard disk of the hard disk drive 23, and the read music data D1 is read from the external device interface unit 28 together with a recording command corresponding to a recording start command. The data is transmitted to the portable recording / reproducing apparatus 2 via the cable 3.

  Thereby, the CPU 20 can record the music data D1 of the group unit on the magneto-optical disk in the portable recording / reproducing apparatus 2.

  Further, the CPU 20 displays a predetermined playback control screen on the display unit 25 during playback control of the music data D1 for the portable recording / playback apparatus 2 (hereinafter referred to as data playback control).

  In this state, when the music data D1 to be reproduced for the portable recording / reproducing device 2 is designated on the reproduction control screen and the reproduction start command is input, the CPU 20 in response to the operation of the operation unit 24 (for example, a mouse). A reproduction command corresponding to the reproduction start command is transmitted from the external device interface unit 28 to the portable recording / reproducing apparatus 2 via the cable 3.

  As a result, when the music data D1 reproduced from the magneto-optical disk in the portable recording / reproducing apparatus 2 is transmitted via the cable 3, the CPU 20 captures the music data D1 via the external device interface unit 28 and captures the music data D1. The music data D1 is converted from digital to analog, and the obtained music signal S1 is sent to the speaker 26, so that the music based on the music signal S1 is output from the speaker 26.

  By the way, the CPU 20 performs a pause command and a playback stop command on the playback control screen in response to an operation of the operation unit 24 (for example, a mouse) while the portable recording / playback device 2 is playing back the music data D1, for example. A fast forward playback command and a fast reverse playback command can be input.

  Further, the CPU 20 follows the music data D1 that is currently being played on the playback control screen in accordance with the operation of the operation unit 24 (for example, a mouse). Next song playback command for switching music data D1 to be played back so as to play back data D1, previous song for switching music data D1 to be played back so as to play music data D1 one track before music data D1 currently being played back Playback command, next group playback command for switching music data D1 to be played back so that the first music data D1 belonging to a group that is one group lower than the group to which the music data D1 currently being played belongs, and music currently being played back Sound to be played so as to play the first music data D1 belonging to the group one group before the group to which the data D1 belongs Group play command or the like before switching the data D1 has also been made so as to input.

  Accordingly, the CPU 20 responds to the operation of the operation unit 24 by such a pause command, playback stop command, fast forward playback command, fast reverse playback command, next music playback command, previous music playback command, next group playback command and previous group playback command. Are input to the portable recording / reproducing apparatus 2 via the cable 3 from the external device interface unit 28 in response to these various commands (hereinafter referred to as a “reproduction control command”).

  Thereby, the CPU 20 can cause the portable recording / reproducing apparatus 2 to execute pause, stop playback, fast forward playback, fast reverse playback, etc. according to the playback control command during playback of the music data D1, Thus, the portable recording / reproducing apparatus 2 can function as a remote controller to execute various reproducing operations.

  Incidentally, the CPU 20 reads hierarchical music management software, a secure module, and a device driver from the hard disk of the hard disk drive 23 at the time of data recording control and data reproduction control.

  Then, the CPU 20 generates various commands according to various commands according to the music management software, and at that time, according to the secure module, in advance, the portable recording / reproducing device 2 to be controlled permits recording / reproducing of the music data D1 in advance. It is determined whether or not recording with respect to the personal computer 4 and whether recording and playback are permitted with respect to the music data D1 to be recorded and reproduced, and the portable recording / reproducing apparatus 2 and the music data are determined. Only when the recording and reproduction of D1 are authenticated, various commands are transmitted to the portable recording / reproducing apparatus 2 according to the device driver, and the above-described series of data recording control processing and data reproduction control processing are executed.

  As a result, the CPU 20 records or reproduces the music data D1 without permission in the portable recording / reproducing apparatus used by a third party, or the music data D1 is illegally ignored by the regular portable recording / reproducing apparatus 2 ignoring the recording / reproducing restrictions. It is possible to prevent recording / reproduction and the like, and thus to properly protect the copyright on the music data D1.

  Further, as shown in FIG. 3, the portable recording / reproducing apparatus 2 has a system controller 30 for comprehensively controlling the portable recording / reproducing apparatus 2 as a whole. When recording the music data D1, a recording command is sent from the personal computer 4. At the same time, when the music data D1 is transmitted via the cable 3, the recording command is taken into the system controller 30 via the buffer 31, and the music data D1 is taken into the encoder 32 via the buffer 31.

  The system controller 30 drives and controls the spindle motor 35 and the optical pickup 36 sequentially via the servo circuit 33 and the motor drive unit 34 in accordance with the recording command, thereby rotating the magneto-optical disk 37 via the spindle motor 35 and The pickup 36 is moved to a predetermined recording start position on one side of the magneto-optical disk 37.

  At this time, the system controller 30 controls the light source of the optical pickup 36 for recording via the laser driver 38 in accordance with the recording command at this time, thereby causing the light source of the optical pickup 36 to emit a light beam for recording output and magneto-optically. One surface of the disk 37 is irradiated.

  Then, the encoder 32 performs predetermined recording processing such as compression encoding and modulation on the music data D1 given from the personal computer 4 and sends the obtained recording music signal S2 to the magnetic head driver 39.

  The magnetic head driver 39 drives and controls the magnetic head 40 disposed opposite to the optical pickup 36 and the other surface side of the magneto-optical disk 37 in accordance with the recording music signal S2, so that the light beam to the magneto-optical disk 37 is controlled. The irradiation position is magnetized by magnetic field modulation, and music data D1 is recorded on the magneto-optical disk 37.

  Further, the system controller 30 takes in the reproduction command via the buffer 31 when a reproduction command is transmitted from the personal computer 4 via the cable 3 during reproduction of the music data D1.

  The system controller 30 rotates the magneto-optical disk 37 via the spindle motor 35 by driving and controlling the spindle motor 35 and the optical pickup 36 sequentially via the servo circuit 33 and the motor drive unit 34 according to the reproduction command. The optical pickup 36 is moved to a predetermined reproduction start position on one side of the magneto-optical disk 37.

  Further, the system controller 30 controls the light source of the optical pickup 36 for reproduction via the laser driver 38 in accordance with the reproduction command.

  As a result, the optical pickup 36 emits a reproduction output light beam from the light source to irradiate one surface of the magneto-optical disk 37, and receives and photoelectrically converts the reflected light obtained by reflecting the light beam on the one surface. The photoelectric signal S3 obtained by this is sent to the RF amplifier 41.

  The RF amplifier 41 corresponds to the reproduction music signal S4 corresponding to the music data D1 with the photoelectric signal S3 and the address information of the irradiation position of the light beam on the magneto-optical disk 37 (that is, the reproduction position of the music data D1 in this case). The reproduction address signal S5 is separated, and the reproduction music signal S4 and the reproduction address signal S5 are sent to the decoder 42.

  The decoder 42 performs a predetermined reproduction process on the reproduction address signal S5, divides the reproduction music signal S4 into predetermined units according to the obtained address information, and demodulates and reproduces the reproduction music signal S4 for each predetermined unit. A predetermined reproduction process such as decoding is performed, and the obtained music data D1 is transmitted from the buffer 31 to the personal computer 4 via the cable 3.

  In this way, the system controller 30 can record and reproduce the music data D1 with respect to the magneto-optical disk 37.

  Incidentally, the optical pickup 36 receives and photoelectrically converts the reflected light obtained by reflecting the light beam on one surface of the magneto-optical disk 37 at the time of recording and reproducing the music data D1, and the obtained photoelectric signal S6 is an RF amplifier. 41.

  Therefore, the RF amplifier 41 generates a tracking error signal S7 and a focus error signal S8 based on the photoelectric signals S3 and S6 given from the optical pickup 36 and sends them to the servo circuit 33 during recording and reproduction of the music data D1. .

  The servo circuit 41 adjusts the tracking and focus of the light beam applied to one surface of the magneto-optical disk 37 by driving and controlling the optical pickup 36 via the drive circuit 34 according to the tracking error signal S7 and the focus error signal S8. Thus, the music data D1 can be recorded and reproduced accurately with respect to the magneto-optical disk 37.

  By the way, when recording the music data D1, the RF amplifier 41 separates the reproduction address signal S9 indicating the address of the laser beam irradiation position (that is, the recording position of the music data D1 in this case) from the photoelectric signal S6. And sent to the address detector 43.

  The address detection unit 43 performs predetermined reproduction processing such as demodulation on the reproduction address signal S9 and sends the obtained address information to the system controller 30.

  When the system controller 30 records the music data D1 on the magneto-optical disk 37, the start address information indicating the recording start position and the end address indicating the recording end position of each music data D1 among the address information given from the address detecting unit 42. Information, start address information indicating the recording start position for each group of music data D1 and end address information indicating the recording end position, the music title and group name of the music based on the music data D1 obtained based on the recording command, etc. Is associated with the above-described information, reproduction additional information (that is, TOC (Table Of Contents)) for the music data D1 to be recorded is generated and sent to the encoder 32 as additional information data D5.

  Then, the system controller 30 drives and controls the optical pickup 36 sequentially through the servo circuit 33 and the motor drive unit 34 so that the optical pickup 36 is opposed to, for example, the innermost lead-in area on one surface side of the magneto-optical disk 37. The lead-in area is irradiated with laser light.

  In this state, the encoder 32 performs predetermined recording processing such as modulation on the additional information data D5, and sends the obtained additional information signal for recording S10 to the magnetic head driver 39.

  Thus, the magnetic head driver 39 drives and controls the magnetic head 40 in accordance with the recording additional information signal S10, thereby magnetizing the irradiation position (that is, the lead-in area) of the laser beam with respect to the magneto-optical disk 37 by magnetic field modulation. Additional reproduction information for the music data D1 is recorded on the magneto-optical disk 37.

  When the system controller 30 starts reproduction processing during reproduction of the music data D1, the system controller 30 first drives and controls the optical pickup 36 via the servo circuit 33 and the motor driving unit 34 in order, thereby controlling the optical pickup 36 to the magneto-optical disk 37. The lead-in area is moved so as to oppose the lead-in area on one side, and the lead-in area is irradiated with the laser beam.

  At this time, the RF amplifier 41 separates the photoelectric signal S3 supplied from the optical pickup 36 into a reproduction additional information signal S11 and a reproduction address signal S5 corresponding to reproduction additional information, and these reproduction additional information signal S11 and reproduction address signal S5. Is sent to the decoder 42, and the reproduction address signal S5 is sent to the address detector 43.

  The decoder 42 performs a predetermined reproduction process on the reproduction address signal S5, divides the reproduction additional information signal S11 into predetermined units according to the obtained address information, and applies to the reproduction additional information signal S11 for each predetermined unit. Predetermined reproduction processing such as demodulation is performed, and the obtained additional information data D5 is sent to the system controller 30.

  As a result, the system controller 30 follows the additional information for reproduction based on the additional information data D5 given from the decoder 42, the song name corresponding to the music data D1, the start address information and the end address information, and the group name for each group of the music data D1. And its start address information and end address information can be recognized.

  In addition, the system controller 30 is given address information from the address detector 43 that operates in the same manner as when the music data D1 is recorded, even when the music data D1 is reproduced.

  Accordingly, the system controller 30 reproduces the next song playback command, the previous song playback command, the next group playback command, and the previous group playback command transmitted from the personal computer 4 through the cable 3 during playback of the music data D1. Is taken in via the buffer 31, based on the address information given from the address detector 43 and the additional information for reproduction, the address information corresponding to the command indicated by the reproduction control command (that is, currently being reproduced) The start address information for the music data D1 to be reproduced instead of the music data D1 is specified.

  Based on the specified address information, the system controller 30 performs drive control of the optical pickup 36 through the servo circuit 33 and the motor drive unit 34 in order to perform seek and replaces with the music data D1 currently being reproduced. The reproduced music data D1 can be reproduced.

  When the system controller 30 takes in the playback control command indicating the fast forward playback command and the fast reverse playback command transmitted from the personal computer 4 via the cable 3 during playback of the music data D1 through the buffer 31, According to the direction according to the command indicated by the playback control command, the optical pickup 36 is driven and controlled through the servo circuit 33 and the motor driving unit 34 in order to move the optical pickup 36 at a high speed, thereby reproducing the music data D1 being played back from the 1x playback. In addition, fast forward playback and fast reverse playback can be performed at a predetermined high speed.

  Further, when the system controller 30 takes in the playback control command indicating the pause command transmitted from the personal computer 4 via the cable 3 during playback of the music data D1 through the buffer 31, the system controller 30 follows the playback control command. The movement of the optical pickup 36 is stopped sequentially through the servo circuit 33 and the motor drive unit 34, and the operation of the decoder 42 is stopped, so that the music data D1 currently being reproduced can be temporarily stopped.

  Incidentally, when the system controller 30 pauses and reproduces the music data D1, the system controller 30 holds the address information given from the address detection unit 43 at that time, so that when the pause is subsequently released, The reproduction for the music data D1 is resumed from the indicated position.

  When the system controller 30 takes in the playback control command indicating the playback stop command transmitted from the personal computer 4 via the cable 3 during playback of the music data D1 through the buffer 31, the servo circuit 33 and The reproduction of the music data D1 is stopped by stopping the operations of the optical pickup 36 and the spindle motor 35 through the motor driving unit 34 and also stopping the operations of the RF amplifier 41, the decoder 42, and the like.

  On the other hand, as shown in FIG. 4, the remote control unit 6 of the earphone 5 with remote control sends an analog music signal S15 corresponding to the music data D1 reproduced by the portable recording / reproducing device 2 to the earphone 7Z of the earphone unit 7. And a pair of command input lines 46 and 47 for inputting a command corresponding to a pressing operation on the operation element 8 to the portable recording / reproducing apparatus 2.

  In addition, a switch 50 having a diaphragm configuration, for example, is provided inside the remote control housing 6Z so as to face the operation element 8, and a period during which the operation element 8 is pressed in accordance with a duration arbitrarily selected by the user (that is, The pair of command input lines 46 and 47 are released from each other by the switch 50 only during a period from when the operating element 8 starts to be pressed with a finger until when the finger is released and the pressing returns to the state before the pressing. It is made so that the ends which are connected may be conducted.

  Accordingly, the system controller 30 of the portable recording / reproducing apparatus 2 (FIG. 3), when the earphone 5 with a remote control is connected to the portable recording / reproducing apparatus 2 instead of the personal computer 4, the instruction detection signal at a predetermined level. S16 is continuously supplied to one command input line 46 of the remote controller 6 via the buffer 31.

  In this state, when the operator 8 of the remote control unit 6 is not pressed, the system controller 30 does not capture the command detection signal S16 because no signal is output from the other command input line 47, and the operator 8 is pressed. Only when the command detection signal S16 is returned from the one command input line 46 via the switch 50 and the other command input line 47 in sequence.

  Further, the system controller 30 is a time (hereinafter, referred to as a reception state continuation time) in which a state in which an operation element 8 of the remote control unit 6 is pressed is received (hereinafter referred to as a command reception state). ), When the instruction detection signal S16 is not taken in from the time when the instruction detection signal S16 is taken in by the internal counter (that is, when the output of the instruction detection signal S16 from the remote control unit 6 stops) Measured as the time until.

  Furthermore, the system controller 30 is in a state in which the command acceptance is canceled (hereinafter referred to as an acceptance cancellation state) in which the operation controller 8 of the remote control unit 6 is once pressed and returned to the state before the press. Is measured as the time from when the instruction detection signal S16 is no longer captured until when the instruction detection signal S16 begins to be captured again.

  Then, when the system controller 30 takes in the command detection signal S16, the reception state continuation time measured according to the signal is selected in advance to determine the type of the command reception state that is distinguished by the difference in duration. It is compared with a predetermined state determination reference time.

  As a result, when the reception state continuation time is shorter than the state determination reference time, the system controller 30 determines that the operation element 8 is pressed for a time that is less than the state determination reference time, and determines the instruction reception state for the operation element 8. Is determined to be the first command reception state that has been continued for a time shorter than the state determination reference time.

  Further, when the reception state continuation time is equal to or longer than the state determination reference time, the system controller 30 determines that the operator 8 has been pressed for the state determination reference time or longer, and the command reception state of the operator 8 continues for the state determination reference time or longer. It is determined that the received second command acceptance state has been reached.

  In addition to this, when the command detection signal S16 is not taken in, the system controller 30 uses the release state duration time measured in accordance with the predetermined detection criterion for determining the end of the pressing operation as a predetermined end determination criterion. Compare with time.

  As a result, when the release state duration time is shorter than the end determination reference time, the system controller 30 temporarily releases the command reception state (that is, the press) between the intermittent presses of the operator 8 a plurality of times. Therefore, it is determined that the pressing operation on the operation element 8 is being executed.

  In addition, when the release state duration time is equal to or greater than the end determination reference time, the system controller 30 does not press the operation element 8 of the remote control unit 6 again even after the end determination reference time has elapsed, so that the acceptance release state is temporary. Rather, it is for ending the pressing operation with respect to the operating element 8, and it is determined that the pressing operation with respect to the operating element 8 has ended.

  In this way, the system controller 30 determines the operation element 8 according to the combination contents of the first and second command reception states determined between the start time and the end time of the pressing operation on the operation element 8 of the remote controller 6. A command input in response to a pressing operation on is identified.

  That is, for example, as shown in FIG. 5, the system controller 30 is in a state before pressing after the operating element 8 of the remote control unit 6 is pressed for a time shorter than the state determination reference time T1 to enter the first command receiving state. If the user presses the button in a procedure that returns to the acceptance cancellation state and continues as it is for the end determination reference time T2 or longer, the reproduction command and the pause command assigned in advance to the pressing operation of the procedure are It is identified as a command input in response to the pressing operation.

  Incidentally, when the pressing operation shown in FIG. 5 is performed on the operation element 8 in a state where the music data D1 is not played back, the system controller 30 identifies the command input according to the pressing operation as a playback command. To do.

  On the other hand, when the pressing operation shown in FIG. 5 is performed on the operation element 8 during the reproduction of the music data D1, the system controller 30 identifies the command input according to the pressing operation as a pause command. To do.

  Further, for example, as shown in FIG. 6, the system controller 30 is returned to the state before the pressing after the operation unit 8 of the remote control unit 6 enters the second command receiving state where the operating unit 8 is pressed for the state determination reference time T1 or more. When a pressing operation is performed in a procedure that shifts to the acceptance canceling state and continues as it is for the end determination reference time T2 or longer, a playback stop command assigned in advance to the pressing operation of the procedure is input according to the pressing operation. Identify as a command.

  In addition to such a configuration, for example, as shown in FIG. 7, the system controller 30 enters the first command reception state in which the operator 8 of the remote control unit 6 is pressed for a time shorter than the state determination reference time T1. Only after a period shorter than the end determination reference time T2, the state is temporarily returned to the state before pressing and shifts to the reception canceling state, and subsequently shifts to the second command receiving state pressed for the state determination reference time T1 or more. A combination of the number of first and second instruction reception states and the order of transition so that the state before the pressing is restored and the state is again shifted to the reception cancellation state, but the reception cancellation state continues for the end determination reference time T2 or more. When a pressing operation is performed on the content, a fast-forward playback command assigned in advance to the pressing operation on the content is identified as a command input in response to the pressing operation.

  In addition to this, the system controller 30, for example, has the operator 8 in a first command reception state, a temporary reception cancellation state, a first command reception state, a temporary reception cancellation state, a second command reception state, and an operation. When a pressing operation is performed with a combination of the number of first and second instruction reception states and the order of transition that sequentially shifts to an end reception cancellation state, the content is assigned in advance to the pressing operation of the content A fast reverse playback command is identified as a command input in response to the pressing operation.

  The system controller 30 also has a first command reception state in which the operator 8 sequentially shifts to a first command reception state, a temporary reception cancellation state, a first command reception state, and an operation termination reception cancellation state. When the pressing operation is performed with the combined content of only the number of times, the next music playback command assigned in advance to the pressing operation of the content is identified as the command input in response to the pressing operation.

  Further, the system controller 30 determines that the operator 8 is in a first command reception state, a temporary reception cancellation state, a first command reception state, a temporary reception cancellation state, a first command reception state, and an operation end reception. When a pressing operation is performed with a combination of only the number of times of the first command reception state that sequentially shifts to the release state, a previous song playback command assigned in advance to the pressing operation of the content is determined according to the pressing operation. Identifies as an input instruction.

  Further, the system controller 30 is in a second command reception state in which the operator 8 sequentially shifts to a second command reception state, a temporary reception cancellation state, a second command reception state, and an operation termination reception cancellation state. When the pressing operation is performed with the combined content of only the number of times, the next group reproduction command assigned in advance to the pressing operation of the content is identified as the command input in response to the pressing operation.

  Further, the system controller 30 determines that the operator 8 is in the second command reception state, the temporary reception cancellation state, the second command reception state, the temporary reception cancellation state, the second command reception state, and the operation end reception. When a pressing operation is performed with a combination of only the number of times of the second command reception state that sequentially shifts to the release state, a previous group reproduction command assigned in advance to the pressing operation of the content is determined according to the pressing operation. Identifies as an input instruction.

  In this way, the system controller 30 temporarily cancels the command accepting state (that is, pressing) of the single operation element 8 for accepting the command with the duration arbitrarily selected by the user, and the command accepting state. The pressing operation is performed so that the reception canceling state is alternately repeated alternately, and the command receiving state (that is, the first and second command receiving states) of the operation element 8 is determined between the start time and the end time of the pressing operation. In addition, it is possible to identify the command input in response to the pressing operation on the operating element 8 based on the combination contents that can be used in combination of the determined number of first and second command receiving states and the order of transition. Has been made.

  Then, the system controller 30 performs various pressing operations on the operation element 8 of the remote control unit 6 to perform a playback command, a pause command, a playback stop command, a fast forward playback command, a fast reverse playback command, a next song playback command, a previous song When a playback command, a next group playback command, and a previous group playback command are input, the light is operated by operating in the same manner as the playback of the music data D1 when the personal computer 4 is connected to the portable recording / playback device 2 described above. Although the music data D1 is reproduced from the magnetic disk 37 in a reproduction state according to the input command, the music data D1 is converted from digital to analog by the buffer 31, and the obtained audio signal S15 is converted to the signal line 45 of the remote control unit 6. Is sent to the earphone 7Z of the earphone unit 7 via.

  Thus, the system controller 30 can make the user listen to music based on the music signal S15 via the earphone 7Z.

  By the way, as shown in FIG. 8, when the operating element 8 of the remote controller 6 is pressed, the system controller 30 recognizes the command inputted in response to the pressing operation, and the operating element that is being pressed. The command notification sound data D7 of the command notification sound for notifying the command input at that time is generated.

  That is, when the command accepting state of the operator 8 becomes the first command accepting state with a relatively short time during the pressing operation on the operator 8, the system controller 30 sets the first command accepting state to, for example, “Pip”. When the command accepting state of the operator 8 becomes a second command accepting state that is longer in time than the first command accepting state, the second command accepting state is set to, for example, “Pee”. The command notification sound is generated by combining the short sound and the long sound in combination with the number of times of the first and second command reception states and the order of transition of the operation element 8 during the pressing operation.

  Incidentally, in the pressing operation shown in FIG. 8, the first instruction acceptance state of the operator 8 is indicated by “A”, the second instruction acceptance state is indicated by “B”, and the acceptance release state for the operation end is indicated by “B”. "C", and the order of transition from the first and second command acceptance states to the operation termination acceptance release state in the operating element 8 during the pressing operation is indicated by arrows.

  The system controller 30 then converts the command notification sound data D7 from digital to analog in the buffer 31, and sends the command notification sound signal S17 obtained to the earphone 7Z via the signal line 45 of the remote control unit 6 to thereby generate the command notification sound data. The command notification sound based on the signal S17 can be heard by the user via the earphone 7Z, and thus the user can confirm the command inputted by the user together with the content of the pressing operation on the operation element 8.

  Here, in practice, when the earphone 5 with a remote control is connected to the portable recording / reproducing apparatus 2, the system controller 30 performs the input command identification processing procedure RT1 shown in FIG. 9 according to the input command identification program stored in advance in the internal memory. The process proceeds to step SP1 after entering from the start step.

  In step SP1, the system controller 30 determines whether or not a pressing operation on the operation element 8 has been started in a state where the command detection signal S16 is sent to the remote control unit 6.

  If a negative result is obtained in step SP1, this means that the instruction detection signal S16 has not yet begun to be taken in, so that the user is not required to listen to music or has already been reproduced. On the other hand, this indicates that no request is made to change the playback state. At this time, the system controller 30 repeats the processing of step SP1 and waits for the start of the pressing operation on the operator 8.

  If an affirmative result is obtained in step SP1, this means that the user has requested to listen to music by starting to capture the command detection signal S16, or the reproduction state of the music data D1 that has already been reproduced. The system controller 30 at this time moves to the following step SP2.

  In step SP2, the system controller 30 determines the type of instruction reception state (that is, one of the first and second instruction reception states) in response to pressing of the operator 8, and proceeds to the subsequent step SP3.

  In step SP3, the system controller 30 determines whether or not the pressing operation on the operation element 8 has been completed.

  If a negative result is obtained in step SP3, this indicates that the operation unit 8 is in the middle of a pressing operation because the operation unit 8 has shifted from the first and second command reception states to the temporary reception cancellation state. At this time, the system controller 30 returns to step SP2 and repeats the processing of step SP2 and step SP3 cyclically until a positive result is obtained at step SP3.

  If an affirmative result is obtained in step SP3, this indicates that the operating element 8 has shifted from the first and second command acceptance states to the operation termination acceptance release state. At this time, the system controller 30 Control goes to step SP4.

  In step SP4, the system controller 30 performs the pressing based on the combination of the number of first and second command reception states and the transition order determined between the start time and the end time of the pressing operation on the operator 8. The command input according to the operation is identified, and the process proceeds to step SP5.

  In step SP5, the system controller 30 outputs a command notification sound for notifying the command input in response to the pressing operation on the operation element 8 from the earphone 7Z, thereby notifying the user of the command input in response to the pressing operation. Then, the process proceeds to step SP6.

  In step SP6, the system controller 30 determines whether or not the music data D1 can be output.

  If a negative result is obtained in this step SP6, this means that the music data D1 is still being played back or the music data D1 is played back after the earphone 5 with remote control is still connected to the portable recording / playback apparatus 2. In this case, the system controller 30 returns to step SP1.

  As a result, the system controller 30 repeats the processing from step SP1 to step SP6 cyclically until a positive result is obtained in step SP6 thereafter, so that each time the operator 8 is pressed, A command input according to the operation is identified, and the command is reflected in the reproduction process of the music data D1.

  If a positive result is obtained in step SP6, this indicates that, for example, the earphone 5 with the remote control has been removed from the portable recording / reproducing apparatus 2. At this time, the system controller 30 moves to the following step SP7 and moves to this step SP7. The input command identification processing procedure RT1 is terminated.

  In this embodiment, when reproducing the music data D1 from the magneto-optical disk 37, the system controller 30 extracts the time code previously added to the music data D1 by the decoder 42, and extracts the extracted time code. At the same time, reproduction state notification screen data D8 is generated from a display indicating the reproduction state and the like, and the generated reproduction state notification screen data D8 is sent to the display unit 9 of the remote control unit 6 via the buffer 31.

  As a result, the system controller 30 can display a reproduction state notification screen based on the reproduction state notification screen data D8 on the display unit 9 of the remote control unit 6 to notify the user of the reproduction state of the music data D1 and the like.

  In the above configuration, when one operating element 8 of the earphone 5 with remote control is pressed down (step SP1), the portable recording / reproducing device 2 is in a command reception state when the operating element 8 is pressed down. It is determined whether it is in the 1st or 2nd command reception state (step SP2), and whether or not the operation element 8 has shifted from the 1st and 2nd command reception state to the reception termination state for operation termination. Is determined (step SP3).

  Then, after the portable recording / reproducing apparatus 2 determines the type of instruction reception state in which the operation element 8 is sequentially shifted while the operation element 8 is being pressed, the operation element 8 receives the first and second instructions. When it is determined that the pressing operation has ended due to the transition from the receiving state to the receiving cancellation state for ending the operation, the first operation state determined as the command receiving state of the operating element 8 between the start time and the end time of the pressing operation is determined. Based on the combination of the number of times for the second command reception state and the order of transition, the command input in response to the pressing operation is identified (step SP4).

  Accordingly, the portable recording / reproducing apparatus 2 can press the single operator 8 intermittently any number of times through the temporary reception cancellation state between the start time and the end time of the pressing operation. In order to discriminate and discriminate the instruction reception state when the operation element 8 is pressed into the first and second instruction reception states having different durations, one operation element 8 is associated with the first and second instruction reception states. It is possible to easily input a large number of commands by pressing with various combinations of the number of times and the order of transition.

  In addition, the portable recording / reproducing apparatus 2 causes the single operator 8 to be pressed by pressing the operator 8 with various combinations of the combination of the number of times of the first and second command reception states and the order of transition. On the other hand, the number of pressings is not simply increased according to the number of commands that can be input, and the pressing operation is not performed, and a large number of commands can be input more easily with the minimum number of pressings.

  Further, the portable recording / reproducing apparatus 2 distinguishes the command reception status of the operation element 8 into two types of first and second command reception statuses having different durations and distinguishes them from the first and second command reception statuses. Since the pressing operation is performed with the combination of the number of times and the order of transition, it is possible to cause the user to input an instruction by pressing the operating element 8 so as to make a relatively simple rhythm.

  According to the above configuration, when one operator 8 of the earphone 5 with remote control is pressed so as to alternately repeat the command acceptance state and the temporary acceptance release state, the command acceptance of the operator 8 is accepted. It is determined whether the state is the first or second instruction acceptance state, and whether or not the operating element 8 has shifted from the first or second instruction acceptance state to the operation termination acceptance release state. When the determination is made and the operation is shifted to the reception cancellation state for the end of the operation and it is determined that the pressing operation has ended, the number of times for the first and second command reception states determined between the start time and the end time of the pressing operation Based on the combination of the transition order and the instruction input in response to the pressing operation, the operator is made aware of which operator is assigned to each instruction. In addition, a single operator 8 makes it possible to easily input a large number of commands only by considering only a combination of at least two types of first and second command reception states, and thus operability when inputting commands. It is possible to realize a portable recording / reproducing apparatus that can significantly improve the above.

  In addition, the portable recording / reproducing apparatus 2 can reduce the number of operators and reduce the size of the remote control unit 6 as compared with the conventional portable recording / reproducing apparatus 2 because a large number of commands can be input with one operator 8. The space where the operation element is conventionally arranged can be easily and effectively used for addition of other functions without increasing the size of the remote control unit 6.

  Further, the portable recording / reproducing apparatus 2 notifies the user of a command input according to the pressing operation at the time when the pressing operation on the operating member 8 is completed, by using a command notification sound. Even when 8 is pressed a plurality of times, it is possible to easily confirm whether or not the command is correctly input.

  When the portable recording / reproducing apparatus 2 notifies the command input in response to the pressing operation of the operating element 8, the portable recording / reproducing apparatus 2 recalls the first and second command receiving states (that is, the pressing state) for the operating element 8. Since the short sound and the long sound to be combined are combined in the order of transition of the first and second command reception states to generate a command notification sound, as the number of pressing operations increases, a command that can be input according to the pressing operation is pressed. It is possible to easily and accurately recognize the pressing state of the operating element 8 in the operation and the pressing order of the state, and the procedure is different from the procedure for the operating element 8 to input a desired command. It is also possible to reduce as much as possible that an erroneous command is input after being pressed.

  In the above-described embodiment, a case has been described in which the command reception state in response to the pressing of the operation element 8 is distinguished from the two types of first and second command reception states by the difference in duration. However, the present invention is not limited to this, and the command reception status in response to the pressing of the operation element 8 may be discriminated into three or more types of command reception status according to the difference in duration. In this way, it is possible to easily input a larger number of commands with a minimum number of pressings on the operation element 8 than in the first embodiment described above.

  Further, in the above-described embodiment, based on the combination contents of the number of first and second command reception states and the order of transition determined between the start time and the end time of the pressing operation on the operation element 8, Although the case where the command input in response to the pressing operation is identified has been described, the present invention is not limited to this, and the first and the first discriminating between the start time and the end time of the pressing operation on the operator 8 are determined. The command input in response to the pressing operation may be identified based on the combined content of only the second command reception state count. Even in this way, a large number of commands can be input by pressing the single operation element 8.

  Furthermore, in the above-described embodiment, the two types of first and second command reception states are determined by the difference in duration based on the state determination reference time selected in advance for the command reception state in response to pressing of the operation element 8. In the above description, the temporary acceptance cancellation state in which the operating element 8 is returned from the pressed state to the unpressed state is also determined based on the end determination reference time selected in advance. However, the determination is not limited to this, but is distinguished by distinguishing at least two types of instruction reception states based on a difference in duration based on a state determination reference time that allows the user to arbitrarily select a command reception state in response to pressing of the operation element 8. In addition, the temporary acceptance cancellation state in which the operation element 8 is returned from the pressed state to the state before the pressed state may be determined based on the end determination reference time arbitrarily selected by the user. In this way, in addition to the effects obtained by the first embodiment described above, the operation element 8 can be appropriately pressed according to the movement of the user's finger, the operation preference, and the like.

  Furthermore, in the above-described embodiment, the case where various commands are input to the portable recording / reproducing apparatus 2 via the operation element 8 of the earphone 5 with remote control has been described. However, the present invention is not limited to this.
