 The device of the present invention will be described below with reference to the drawings. FIG. 2 is a block diagram illustrating a first embodiment of the device of the present invention. This embodiment embodies the device of the present invention having the configuration of FIG. The CD autochanger player 50 corresponds to the automatic exchange / playback device 10 of FIG. The CD autochanger player 50 selects one of the stored CDs according to the request information input by the user and outputs a reproduction signal of recorded acoustic information. As is well known, a CD is an information recording medium on which acoustic information is recorded. A maximum of M CDs can be stored in this CD autochanger player, and the stored CDs are arranged at the respective CD arrangement positions of the CD holding portion. When the user wants to specify a particular CD in the request information input to the CD autochanger player 50, numbers from 1 to the maximum number M of stored sheets are available. These numbers have a one-to-one correspondence with the CD arrangement position of the CD holding portion of the CD autochanger player 50. Now, it is assumed that N (1 ≦ N ≦ M) CDs are stored in the CD auto changer player 50.

The first solid-state IC 54 converts a part of the acoustic information of each CD read out after being converted from digital information to analog information by the CD autochanger player 50 into digital information, and as the heading information of each CD, the first solid-state IC 54. It is recorded in the internal memory of the. The internal memory of the first solid state IC 54 corresponds to the information recording medium 15 for recording the header information. Further, when reproducing the headline information, the first solid-state IC 54 converts the recorded digital information into analog information and outputs it. In the internal memory of the second solid state IC 56, audio information for notifying numbers 1 to M that can be used when designating a specific CD in the request information input to the CD autochanger player 50 is digitally displayed. It is recorded as information. At the time of reproducing the voice information, the second solid state IC 56 converts the voice information from digital information into analog information and outputs it.

The input section 62 is provided with a heading information reproduction button capable of inputting a heading information reproduction command for sequentially reproducing each heading information recorded in the first solid state IC 54. This heading information reproduction button corresponds to the heading information reproduction command input means 22. In addition, the input section 62 is also provided with a heading information recording button for inputting a heading information recording command for causing the CD autochanger player 50 to read the heading information and record it in the first solid state IC 54.

As is well known, the microcomputer 52 is composed of a CPU 52A, a ROM 52B, a RAM 52C and an interface 52D. A program for the microcomputer 52 to function as the headline information recording means 14, the headline information reproducing means 26, or the information notifying means 32 is written in the ROM 52B of the micro computer 52 together with the first individual IC or the second solid state IC. There is.

FIG. 3 shows a flowchart of the main routine of this program. At the first step S1, the microcomputer 52 is powered on and at the same time the first subroutine is called. By this subroutine, the microcomputer 52 and the first solid state IC 54 function as the headline information recording means 14. In the second step S2, it is checked whether or not a heading information recording command has been input. In this step, when the user replaces the CD with the CD auto changer player 52, the user is asked whether or not the heading information of each CD is newly recorded. When the user updates the headline information, the process returns to the first step S1. If the heading information is not updated, the process proceeds to the third step S3. In the third step S3, it is checked whether or not the headline information reproduction button of the input unit 62 has been operated to input the headline information reproduction command. If no find information reproducing command has been input, the process returns to the second step S2. When the headline information reproducing command is input, the process proceeds to the fourth step S4. In the fourth step S4, the second subroutine is called. The microcomputer 52 and the first solid state IC 54 function as the headline information reproducing means 26 by the second subroutine. At the same time, the microcomputer 52 and the second solid state IC 56 function as the information notifying means 32. After the processing of the second subroutine is completed, the process returns to the second step S2 again, and the above steps are repeated.

FIG. 4 is a flowchart of the first subroutine of the program. In this program, there is a one-to-one correspondence with the CD placement position of the CD autochanger player 50, and n (as a variable that represents a number that can be used when a specific CD is specified in the request information input to the CD autochanger player 50). 1 ≦ n ≦ M; M is the maximum number of CDs stored in the CD autochanger player 50). Further, in this program, when the heading information of the CD arranged at the CD arrangement position corresponding to the number n is written in the memory of the first solid state IC 54, the recording start address and the recording end address of the memory of the first solid state IC 54 are recorded. A record R (n) (1 ≤ n ≤ M; n is a natural number) is created on the RAM 52C of the microcomputer. With this record, it is possible to manage the correspondence between the CD headline information and the CD layout position.

In the first step S1 of the flowchart of FIG. 4, the initial value 1 is set to the above number n. This number n is incremented by 1 in the fifth step S5. In the second step S2, it is checked whether or not the CD is placed at the CD placement position corresponding to the number n. If no CD is placed, the process proceeds to the third step S3. In the third step S3, a code "?" Is recorded in the record R (n) in order to identify that the CD is not arranged. After that, in the fourth step S4, it is checked whether or not n is equal to the maximum value, and depending on the result, the process returns to the main routine, or in the fifth step S5, n is incremented by 1, and then the process returns to the second step S2. When it is recognized that the CD is arranged in the second step S2, the recording start address of the memory of the first solid-state IC 54 is designated and output to the first solid-state IC 54 in the sixth step S6. At the same time, the recording start address is recorded in the record R (n). In the seventh step S7, the CD autochanger player 50 is caused to partially read out the acoustic information of the CD at the CD arrangement position corresponding to the number n, and to record it in the first solid state IC 54 as heading information. In the eighth step S8, the recording end address of this heading information is recorded in the record R (n), and the process proceeds to the fourth step S4. In the fourth step S4, it is checked whether or not the number n has reached the maximum value M. If n has not reached the maximum value M, the process proceeds to the fifth step S5, 1 is added to n, and the process returns to the second step S2. When n reaches the maximum value M, it returns to the main routine.

FIG. 5 is a flowchart of the second subroutine of the program. In the first step S1, an initial value 1 is set to the variable n having the number used in the first subroutine. This number n is incremented by 1 in the fourth step S4. In the second step S2, it is checked whether or not the recording start address of the headline information is recorded in the record R (n). That is, check whether or not there is a "?" Sign. If the recording start address is not recorded, the process proceeds to the third step S3. In the third step, it is checked whether or not n is equal to the maximum value, and depending on the result, the process returns to the main routine, or 1 is added to n in the fourth step S4 and then the process returns to the second step S2. If the recording start address is recorded, the process proceeds to the fifth step S5. In the fifth step S5, the second solid state IC 56 is caused to reproduce the voice information of the number n, and to notify it like "disk number n". In the sixth step S6, the recording start address and recording end address of the heading information are read from the record R (n) of number n. In the seventh step S7, the first solid state IC 54 is caused to read the heading information determined by the recording start address and the recording end address read in the third step S3, and the reproduction signal is produced and output. After this, the process proceeds to the third step S3 to check whether or not the number n has reached the maximum value M. If n has not reached the maximum value M, the process proceeds to the fourth step S4, 1 is added to n and the process returns to the second step S2. When n reaches the maximum value M, the process returns to the main routine of FIG. By the first step S1 to the fourth step and the sixth step S6 to the seventh step S7 of the second subroutine, the microcomputer 52 and the second solid state IC function as a heading information reproducing means. Further, the microcomputer 52 and the second solid state IC 56 function as the information notifying means 32 by the first step S1 to the fifth step S5 of the second subroutine.

Next, a second embodiment of the device of the present invention will be described. The configuration of the device is the same as in FIG. However, the program written in the ROM 52B of the microcomputer is provided with the third subroutine in place of the second subroutine. Along with this, instead of the heading information reproduction button of the input unit 62, a heading / normal reproduction button that can input both a heading information reproduction command and a normal reproduction command is provided. This button normally functions as a button for inputting a heading information reproducing command, and functions as a button for inputting a normal reproducing command when the heading information is reproduced. The signal generated by operating the operation button is distinguished by whether or not the heading information is being reproduced. This embodiment embodies the device of the present invention having the configuration shown in FIG.

The first step S1 to the seventh step S7 are the same as in the flow chart of the second subroutine of FIG. 5, the number n is notified, and the information for the record R (n) of the number n is used to output the reproduction signal of the heading information as the first solid. Output to IC54. In the eighth step S8, it is checked whether or not the index / normal reproduction button is operated and the normal reproduction command is input while the index information is reproduced in the seventh step S7. If the normal reproduction command has not been input, the process proceeds to the third step S3 to check whether n has reached the maximum value M or not. When n has not reached the maximum value M, the process proceeds to the fourth step S4, 1 is added to n, and the process returns to the second step S2. If n has reached the maximum value M, return to the main routine. When it is recognized in the eighth step S8 that the normal reproduction command is input, the process proceeds to the ninth step S9. In the ninth step S9, the reproduction of the headline information is stopped. In the tenth step S10, the CD automatic changer player 50 is caused to read the acoustic information of the CD at the CD arrangement position corresponding to the number n from the beginning, and to produce and output the reproduction signal. After this, the process returns to the main routine.

In the second embodiment, the heading information reproduction command and the normal reproduction command can be input with one button, but they may be divided into two buttons. In the above-mentioned two embodiments, the headline information reproduction command is input by the user manually operating the operation button, but there is also a method of automatically inputting it. For example, at the same time when the power of the CD auto changer player 50 is turned on, the CD auto changer player 50 outputs the signal of the heading information reproducing command. An input terminal for inputting this signal is provided in the input section 62 in advance. In the above two embodiments, the first solid state IC 54 having the memory as the information recording medium 15 therein is used as the heading information recording means 14 together with the microcomputer 52. In addition, information recording means for recording on a removable information recording medium such as a magneto-optical disk, a magnetic tape or a magnetic disk can be used. In the above two embodiments, the CD autochanger player 50 for a CD in which only audio information is recorded is used as a target to which the device of the present invention is applied, but both audio information and video information are recorded. It is also possible to use an autochanger player for the existing karaoke optical discs. In this case, by providing the heading information recording means 14 with a function of recording video information, not only acoustic information but also image information can be used as heading information.
