Abstract:
A system control portion of a voice data recording and reproducing apparatus converts inputted voice signals into digitized voice data, adds header information stored in a table composed of a rewritable nonvolatile storage medium to the converted voice data and records them in a semiconductor memory as a recording medium. A PC to which such a voice data recording and reproducing apparatus can be connected acquires header information stored in the data table, and, when the changing of the header information is designated, sends the changed header information to the voice data recording and reproducing apparatus. Based upon the sent header information, the system control portion of the voice recording and reproducing apparatus rewrites the header information in the data table.

Description:
CROSS-REFERENCE TO THE RELATED APPLICATIONS 
   This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2000-022752, filed Jan. 31, 2000, the entire contents of which are incorporated herein by reference. 
   BACKGROUND OF THE INVENTION 
   The present invention relates to a voice recording and reproducing apparatus digitizing inputted voice and recording them in a recording medium, an information processing apparatus being connectable to such a voice recording and reproducing apparatus, and a recording medium having recorded an information processing program causing a computer to function as such an information processing apparatus. 
   Generally, the voice recording and reproducing apparatus, that is, the tape recorder has an application in dictation recording. In this dictation recording the tape recorder is used in various ways, for example, the content of a letter to be sent is recorded on an audio tape by a tape recorder, this audio tape is delivered to a secretary or the like, and this secretary or the like plays back the tape, listens to the voice and types the letter, or the content of a meeting is recorded and subsequently minutes of the meeting are taken by playing back the tape and listening to the recorded content. 
   And in recent years, in the voice recording and reproducing apparatus, due to demand for a miniaturized apparatus there have been developed apparatus using a semiconductor memory instead of a magnetic tape as a recording medium. 
   Among such voice recording and reproducing apparatus recording voice data in the semiconductor memory, there are some having a composition in which the semiconductor memory cannot be detached from the main body of the apparatus. In such an apparatus, when desiring to deliver recorded voice data to a secretary or the like and to have a document typed, that is, when desiring to use voice data recorded in this semiconductor memory in an external apparatus such as a voice reproducing apparatus other than the concerned apparatus, the voice data is transmitted to the external apparatus via a cable connected between both apparatuses. 
   Here, since personal computers (PCs) are widely applied recently, documents are usually typed by a word processor operating on this PC. Generally this PC is equipped with a sound function and is capable of reproducing and outputting voice data by a speaker connected thereto. Therefore, a method of transmitting recorded data from the voice data recording and reproducing apparatus to the PC and type-inputting the voice data by a word processor with reproducing them on the PC is now used. 
   And recently, PCs having employed an interface specification permitting connection of many devices called USB (Universal Serial Bus) based upon a so-called Plug and Play function are widely applied. 
   By the way, in a voice recording and reproducing apparatus using a semiconductor memory as described above as a recording medium, when voice data are recorded, they are recorded in the semiconductor memory as a voice data file to which header information has been added. This header information includes many kinds of information such as information for identifying the recorder of the voice data and the typist, recording mode, recording date or the like. 
   With respect to information which the operator can set optionally among this header information, since the voice recording and reproducing apparatus is provided with only several operating buttons, it is required to select and designate such information from a hierarchically structured menu, what is very complicated and is liable to lead to operational failures. 
   BRIEF SUMMARY OF THE INVENTION 
   The present invention has been made in consideration of the above-described circumstances and has an object of providing a voice recording and reproducing apparatus being capable of setting each information of the voice recording and reproducing apparatus by enabling the information processing apparatus such as a PC or the like to set each information, an information processing apparatus, and a recording medium having recorded an information processing program.

   DETAILED DESCRIPTION OF THE INVENTION 
   Now, referring to the drawing, one embodiment of the present invention will be described. 
   In  FIG. 1 , one embodiment of an information processing apparatus to which a plurality of voice recording and reproducing apparatus are connectable and which can exchange data with the voice recording and reproducing apparatus, a personal computer (PC)  10  is shown. Further, one embodiment of one of the voice recording and reproducing apparatus composed as a plurality of USB device connected to the PC  10 , a voice data recording and reproducing apparatus  20  is shown. 
   Here, in the voice data recording and reproducing apparatus  20 , a microphone (MIC)  21  is connected to a system control portion  25  via an amplifier (AMP)  22 , a low-pass filter (LPF) and an analog/digital converter  24 . 
   Although not shown in particular, this system control portion  25  contains a digital signal processing portion (DSP) as an encoding/decoding circuit for compressing/expanding voice data and a CPU for controlling each portion of the voice data recording and reproducing apparatus  20 . Further, this system control portion  25  contains a data table  25 A composed of a rewritable nonvolatile recording medium such as an EEPROM having stored various information such as a type name for identifying the voice data recording and reproducing apparatus and header information as described below. 
   To this system control portion  25  a nonvolatile semiconductor memory  26  as a recording medium for recording voice data and a power source control portion  27  are connected. Moreover, to this system control portion  25  a speaker  31  is connected via a digital/analog (D/A) converter  28 , a LFP  29  and a power AMP  30 . 
   Further, to this system control portion  25  a operational input portion  32  is connected. Although not shown in particular, operational input portion  32  includes a playback button, a fast-forward button, a rewind button, an Imark button, an Emark button, an endless recording switching button or the like in addition to the record button REC and the stop button STOP. 
   Here, the I-mark and the E-mark are as described below. That is, since a plurality of voice data are recorded in the semiconductor memory  26 , in this kind of voice data recording and reproducing apparatus, a recorder can record an instruction (I) mark showing priority relations among a plurality of voice data recorded in the semiconductor memory  26 , that is, an index mark for giving instructions to a typist or secretary, by operating the I-mark button in recording voice data. Accordingly, the recorder can instruct priority relations concretely by voice by using this I-mark. Moreover, the recorder can record an index mark called an end (E) mark by operating the E-mark button in order to show punctuations among a plurality of voice data. 
   Moreover, to the system control portion  25  a data conversion portion for data transfer  33  is connected in order to communicate with the PC  10  via an USE cable  40 . This data conversion portion for data transfer  33  constitutes a means for receiving data from external apparatus such as a PC or the like, a means for sending a connection confirmation completion signal to external apparatus and a means for sending data. Moreover, the data conversion portion for data transfer  33  supplies a connection confirmation completion signal  34  to a terminal T 1  of the system control portion  25  when the USB cable  40  has been connected. 
   That is, in the voice data recording and reproducing apparatus  20 , analog signals obtained from the MIC  21  are amplified by the AMP  22  and passed through the LPF  23 , and subsequently, they are converted into digital signals by the A/D converter  24 , inputted into the system control portion  25  and are encoded, and these encoded voice data are recorded in the semiconductor memory  26 . At this time, header information recorded in the data table  25 A is added to voice data, and the voice data are recorded as a voice file. 
   Moreover, voice data recorded in the semiconductor memory  26  are read out and decoded by the system control portion  25 , and these decoded read-out data are inputted into the D/A converter  28  and converted into analog signals via the LPF  29 . And the signals outputted from this LPF  29  are amplified by the power AMP  30  and outputted outside from the speaker  30  as sounds. 
   Further, the voice data recorded in the semiconductor memory  26  is read out by the system control portion  25 , inputted into the data conversion portion for data transfer  33  and transferred to the PC  10  via the USB cable  40 . 
     FIG. 2  is a view showing the content of header information stored in the data table  25 A. That is, this data table  25 A stores “Author ID”, “Work Type ID”, “Option Item name”, “Option Item ID” or the like. 
   Here, the “Author ID” is the ID or real name of an dictating user, and  10  items of data consisting of 16 bytes respectively can be registered in alphanumeric characters. Moreover, the “Work Type ID” is the ID or real name of a job, and 10 items of data consisting of 16 bytes respectively can be registered in alphanumeric characters. “Option Item name” is the name of an item displayed on a display portion (not shown) of the voice data recording and reproducing apparatus  20  as a menu, and one item of data consisting of 8 bytes is registered in alphanumeric characters. And the “Option Item ID” is the ID of an item which is different in each company, and one item of data consisting of 20 bytes is registered in alphanumeric characters. 
   For example, if used in a hospital, the “Author ID” will be allocated to the name of a doctor, the “Work Type ID” to the name of a department such as internal department, and the “Option Item ID” to the health insurance number or the like. 
   Moreover, as described above, the header information recorded in the data table  25 A is added to the voice data corresponding to the voice inputted from the MIC  21 , and these voice data are recorded as a voice data file in the semiconductor memory  26 . Here, the header portion of the voice data file includes, as shown in  FIG. 3 , various data set by the user or automatically. Further, in the same figure, the “INDEX mark” corresponds to the I-mark, and the “Extended INDEX mark” corresponds to the E-mark. Moreover, the “Work Classification code” corresponds to the “Work Type ID”. Before being written in the file, these data are stored suitably in the data table  25 A. 
   Now, the operations of the PC  10  to which a plurality of voice data recording and reproducing apparatus  20  having the above-described structure can be connected will be described. 
   That is, in the PC  10 , when the control program of this voice data recording and reproducing apparatus  20  is started, initial settings such as settings of screen display, each parameter or the like are made. In these initial settings, for setting each parameter, a connection routine as shown in  FIG. 4  is executed. That is, in this connection routine, first, a connection confirmation and data table creating subroutine is called (Step S 1 ). More specifically, this subroutine is to identify all USB devices connected to the PC  10  and to create a data table showing the USB devices connected to the PC  10 . And subsequently, based upon the data table created by means of this subroutine and stored in a RAM (not shown), a control switching (parameter setting) subroutine for the voice data recording and reproducing apparatus  20  which is a desired USB device is called (Step S 2 ). 
   Here, the connection confirmation and data table creating subroutine in the Step S 1  is as shown in  FIG. 5 . That is, first as the initial setting of a connection number, the internal counter N (not shown) is reset to “0” (Step S 11 ). And subsequently, a request for identification code transfer is sent to the USB device having a connection number N shown in this counter N (Step S 12 ). And, for a predetermined period of time, the system waits to receive data (identification code) (Step S 13 ). Here, it is judged if the N-th USB device is connected accordingly as the data have been received or not (Step S 14 ), and if it is not connected, this connection confirmation and data table creating subroutine is terminated and the procedure returns to an upper connection routine. 
   On the other hand, when it is judged that the N-th USB device is connected, this connection number (number N) and the received identification code are recorded additionally in a data table created in the RAM (not shown) in the PC  10  (Step S 15 ). Here, the identification code includes, for example, the model name information of the USB device (the connected device type, that is, the device type name) and the user ID information (ID number, that is, the “Author ID”). And “1” is added to the connection number N shown in the counter N (Step S 16 ), the procedure returns to the Step S 12 , and the request for identification code transfer is sent to the next USB device. 
   By repeating the Steps S 12  to S 16 , the list of all the connected USB device is created as a data table and stored in the RAM (not shown). 
   Further, in this embodiment, it is assumed that a connection number is allocated automatically from “0” sequentially to the devices connected to the PC  10 . 
   Moreover, the control switching (parameter setting) subroutine in the Step S 2  is as shown in  FIG. 6 . That is, first, the determination of the connected recorder is processed (Step  21 ). In this processing, by displaying the list of all the USB device connected to the PC  10  recorded in the data table, that is, the list of the connection numbers, on the monitor and by receiving a connection number inputted by the operator, a voice data recording and reproducing apparatus (recorder)  20  which is an USB device desired by the operator is selected. 
   And subsequently, a recorder identification code is acquired again from the device having the connection number selected and inputted by the operator, is compared with the corresponding recorder identification code (connected device type and ID number) recorded in the data table and is confirmed (Step S 22 ). In the connection confirmation and data table creating subroutine, the connection-confirmed USB device may be disconnected or added lastly while it is being confirmed if USB device to be connected later than the connection-confirmed USB device are connected, and therefore, this Step S 22  is executed for confirming again if the connection-confirmed USB device is connected. 
   Next, it is judged if the operator of the PC  10  has carried out an operation for changing the ID number, that is, the “Author ID”, in the USB device, in this case, in the voice data recording and reproducing apparatus  20  (Step S 23 ). Here, if the operation for changing the ID number is not carried out, this control switching subroutine is terminated and the procedure returns to an upper connection routine. 
   On the other hand, if the operation for changing the ID number is carried out, a request for data table change is sent to the voice data recording and reproducing apparatus  20 , and a new ID number set by the operator is sent (Step S 24 ). And, after the data table stored in the RAM (not shown) has been updated, that is, the identification code has been changed (Step S 25 ), this control switching subroutine is terminated and the procedure returns to an upper connection routine. 
   Further, for simplification, this control switching subroutine shows a processing for changing the ID number only as a representative example, and it is without saying that various data of the voice data recording and reproducing apparatus  20  such as the “Work Type ID” or the like are also changed in this subroutine. 
   For example, data as shown in  FIG. 7  are transferred from the PC  10  to the voice data recording and reproducing apparatus  20 , and the data in the data table  25 A can be updated. That is, here, “Author Entry Number” is the number of the registered “Author ID”, and “Author IDn” is a 16-digit value of the n-th “Author ID”. “Work Type Entry Number” is the number of the registered “Work Type ID”, and “Work Type IDn” is a 16-digit value of the n-th “Work Type ID”. And “Option Item Name” is a 16-digit item name. 
   Moreover, the operator not only specifies, as in the Step S 23 , the transfer of these data optionally, but naturally these data may be also transferred automatically at the beginning of connection, thereby updating the data in the data table  25 A. 
   After completion of the initial settings, in the PC  10 , when the main screen for controlling the voice data recording and reproducing apparatus  20  is displayed on the monitor and a file transfer processing is instructed by mouse or keyboard input, the specified file is received from the voice recording and reproducing apparatus  20  via an USB cable  40 . And, when file reproduction is instructed, a file reproduction command is sent to the voice data recording and reproducing apparatus  20 , and the specified file is reproduced in the voice data recording and reproducing apparatus  20 . When recorder-recorded information confirmation is instructed, a number of records confirmation command is sent to the voice data recording and reproducing apparatus  20 , and the number of records recorded in the semiconductor memory  26  and sent back from the voice data recording and reproducing apparatus  20  corresponding thereto is displayed on the monitor. Moreover, when PC time setting is instructed, a time setting command (including time data measured by a clock built in the PC) is sent to the voice data recording and reproducing apparatus  20 , and the built-in clock is thereby synchronized with the PC time in the voice data recording and reproducing apparatus  20 . When a recording processing is instructed, a recording processing command is sent to the voice data recording and reproducing apparatus  20 , and voice data are thereby recorded in the semiconductor memory in the voice data recording and reproducing apparatus  20 . And, when the termination of this control program is instructed, a command for switching the power source of the voice data recording and reproducing apparatus  20  to low power is sent to the voice data recording and reproducing apparatus  20 , and the voice data recording and reproducing apparatus  20  is thereby shifted to power-saving mode. Like this, the voice data recording and reproducing apparatus  20  can be controlled from the PC  10 . 
   On the other hand, in the voice data recording and reproducing apparatus  20 , the system control portion  25  operates like a main routine shown in  FIG. 8 . 
   That is, corresponding to the throw-in of the power source switch (not shown), an internal work memory, a register or the like (not shown) are first initialized (Step S 31 ), and subsequently, it is judged whether any operating button of the operational input portion  32  has been operated or not (Step S 32 ). And, when the record button REC is pushed (Step S 33 ), the recording processing is executed (Step S 34 ). When the playback button (not shown) is pushed (Step S 35 ), a playback processing is executed (Step S 36 ). Moreover, when the fast-forward button (not shown) is pushed (Step S 37 ), a fast-forward processing is executed (Step S 33 ). When the rewind button (not shown) is pushed (Step S 39 ), a rewind processing is executed (Step S 40 ) Since these recording processing, play back processing, fast-forward processing and rewind processing are the same as the conventional ones, the details thereof are omitted here. 
   This subroutine is executed as shown in  FIG. 9 . That is, first, it is judged whether there is a request for identification code transfer from the PC  10  or not (Step S 42 A). When the request for identification code transfer is received by the data conversion portion for data transfer  33  from the PC  10  via the USB cable  40  due to the processing in the Step S 12 , the judgment in this Step S 42 A becomes “YES”. In this case, the system control portion  25  reads out a recorder identification code including the device type name, the “Author ID” or the like stored in the data table  25 A in the system control portion  25  (Step S 42 B). And, after this readout recorder identification code has been transferred to the PC  10  (Step S 42 C), the procedure returns to the Step S 42 A. 
   On the other hand, when it is judged in the Step S 42 A that there is no request for identification code transfer, it is further judged whether there is a request for data table change or not (Step S 42 D). When the request for data table change is sent from the PC  10  via the USB cable  40  as in the processing in the Step S 24 , it is received by the data conversion portion for data transfer  33 , and the judgment in this Step S 42 D becomes “YES”. In this case, the system control portion  25  executes a data table change processing (Step S 42 E). The details of this data table change processing are omitted here, but in this processing data sent after the request for data table change are received and the data table  25 A is updated. Accordingly, this system control portion  25  functions as a changing means. And, after completion of this data table change processing, the procedure returns to the Step S 42 A. 
   On the other hand, when no request for data table change has been received in the Step S 42 D, it is judged whether there is a request for remote control of the voice data recording and reproducing apparatus  20  from the PC  10  including voice recording, reproduction or the like as described above or not, and a processing corresponding thereto is executed. However, since this is not a characteristic part of the present invention, the illustration and description thereof are omitted. 
   And, when there are no control signals from the PC  10 , it is further judged whether the connector is disconnected or not (Step S 42 F). And, when the connector is not disconnected, the procedure returns to the Step S 42 A, and when the connector is disconnected, the procedure returns to an upper main routine. 
   As described above, in this embodiment, when a plurality of voice data recording and reproducing apparatus  20  being capable of transferring a recorder identification code including device type name and ID number to the PC  10  are connected, the concerned voice data recording and reproducing apparatus  20  is identified by the recorder identification code, and subsequently, the recorder identification code and the header information of the voice file can be updated. 
   Although the present invention has been described in one embodiment, it is to be understood that the present invention is not limited to the above-described one embodiment and that various modifications and applications may be made without departing from the scope of the summary of the present invention. 
   For example, having described the present invention as related to a voice data recording and reproducing apparatus recording and reproducing voice data as a voice recording and reproducing apparatus connected to an information processing apparatus, it is without saying that the present invention may be applied to apparatus recording and reproducing other data such as image data or the like. Moreover, it has been described that both apparatus are connected with each other by USE, however, the connection of both apparatus is not limited thereto. 
   Further, in the above-described one embodiment, the data table  25 A of the voice data recording and reproducing apparatus  20  is updated, however, it is without saying that the header information of the voice file stored in the semiconductor memory  26  may be changed. 
   Moreover, it is also possible to rewrite the control program of the system control portion  25  of the voice data recording and reproducing apparatus  20  from the PC  10 . 
   Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
