2, 1991).

[0006]

However, conventionally,
In a CD-ROM library system in a library, for example, since the number of CD-ROMs installed and the number of CD-ROM readers installed are fixed, the CD-ROM library system of a size desired by the library cannot be selected. There is. Further, such a library system has a problem that its scale cannot be freely expanded after the system is introduced.

[0007] Further, the conventional CD-ROM library system has a fixed scale. For example, when a plurality of users try to browse one CD-ROM at the same time, the second and subsequent users are required. There is a problem that a waiting time is generated.

Accordingly, in such a library system of a library using CD-ROMs, when access is concentrated on a specific popular CD-ROM, it takes a lot of time to finish processing all accesses. As a result, there is a problem that a user who has delayed access timing has a longer waiting time or cannot access.

Further, the conventional CD-ROM library system is not a system for centrally managing the CD-ROM usage status including the frequency of use of each CD-ROM within a certain period, so that it is not operated for the introducing side. There is a problem that it is difficult to do.

A first object of the present invention is to make it possible to freely set the scale of a system, such as changing the number of ROMs , even after the introduction of a ROM library system.

A plurality of user terminals, information specified in the first storage means for storing management information indicating a correspondence relationship between the reader that is mounted to the recording information for each ROM, the access request from the user terminal The reading device equipped with the ROM recording the information is extracted by the management information, and the R which records the information designated by the user in the reading device is recorded.
Processing means for reading recorded information of the OM and returning the read information to the user terminal of the access request source.

In order to achieve the second object, the present invention provides a second storage means for storing an accessed ROM in a unit of a reading device, and a second storage means for receiving an access request from a user. It is determined whether or not the ROM storing the information designated by the user is being accessed based on the information stored in the storage means, and if the ROM is being accessed, the same information is recorded.
Control means for distributing accesses to other ROMs .

In order to achieve the third object, the present invention comprises a third storage means for storing a ROM use status including a use frequency of the plurality of ROMs in a certain period.

[0016]

According to the first means, the ROM according to the present invention is provided.
Library system includes multiple ROMs with the same information
A ROM group, and a plurality of reading apparatus for reading recorded information of each ROM of the ROM group, a plurality of a user terminal, and correspondence between the reading device information and the ROM of the ROM is mounted The indicated management information is stored in the first storage means.

Further, when an access request is made from the user terminal, a ROM storing information designated by a user from management information stored in the first storage means.
The reading device to which is attached is extracted.

Then, the read information is read from the ROM recorded with the information specified by the user by the reading device, and the read information is returned by the processing means to the user terminal of the access request source. It has become.

Hereinafter, the user "XX Taro" will be described with reference to FIG.
The following describes a procedure for browsing books on the CD-ROM 5 of "Kaguyahime".

First, the user “XX Taro” starts connection to the CPU 1 via the communication LAN line 7 using the user ID 212 from the browsing terminal device 8 in the research room 9 or the browsing room 10. (Step 41).

Then, the user management program 11 searches the user management information file 21 using the input user ID 212 as a key, checks whether the input user is registered as a user, and establishes a connection. It is determined whether or not it is acceptable (step 42). “XX Taro” is registered as a user, so the connection is accepted.

Next, the CD-RO that the user wishes to browse
Access by inputting the title of M5 (step 4
3). Here, the CD-ROM 5 of “KAGUYAHIME” is accessed.

Then, the user management program 11 refers to the user management information file 21 and checks whether this user has an access right to the corresponding CD-ROM 5 (step 44). "KAGUY" is added to the access prohibited CD-ROM ID 213 of "XX Taro".
"A"("Kaguyahime") is not included and therefore has access rights.

Next, the usage status management program 14 searches the CD-ROM management information file 22 using the title input by the user having the access right as a key, and refers to the access status table 31 to find the corresponding title. CD-RO
It is checked in M5 whether there is a CD-ROM 5 that is currently free (step 45).

From the CD-ROM management information file 22, the CD-ROM ID 222 of "KAGUYAHIME" is "KA
GUYA ", and it can be seen that five CD-ROMs 5 of" KAGUYAHIME "are installed. Also, according to the access status table 31, the CD of “KAGUYAHIME” currently used is
-Since there are two ROMs 5, it can be seen that the remaining three are accessible.

When the access control program 15 finds that access is possible, the access control program 15 instructs the logical drive of the CD-ROM reading device 4 corresponding to the CD-ROM 5 to access the free CD-ROM 5 and (Step 46), the CD-ROM ID 311 and the access start time 312 of the CD-ROM 5 that has newly started access are added to the access state table 31.

When the access is completed, the charging management program 13 refers to the charging basic information 225 of the CD-ROM management information file 22, and checks whether or not the browsed CD-ROM 5 is to be charged (step 47). If it is a billing target, a billing calculation is performed based on the access time obtained from the difference between the access end time and the access start time 312 of the access state table 31 and the billing basic information 225, and the user ID 212 or the user ID 212 is calculated. The usage fee is recorded in the accounting management file 23 of the accounting person ID 231 that matches the included affiliation code (step 48).

Next, "1" is added to the number of accesses 242 of the usage status management file 24, and the charge amount of the current access is added to the total charge 243 (step 49).

As described above, the processing from step 43 to step 49 is repeated until there are no more books on the CD-ROM 5 desired by the user (step 50).

When all browsing is completed, the connection to the network is terminated (step 51), and the browsing process is terminated.

As described above, the CD-ROM library system is operated by a series of processes, and the system responds according to the user's access.

Although the present embodiment is an example in which a library of a school or a local government is assumed, the present invention may be used for viewing articles and research data at a university or a research institute.

Further, such a national public institution is a CD-R
When the OM-ized book browsing service is made available to users free of charge, the basic charging information for all CD-ROMs may be set to "0" yen from the beginning of the introduction of the CD-ROM library system according to the present invention. .

In this embodiment, a method using a CD-ROM in which characters and still image information are recorded has been described. However, a CD (Compact Disc) or an LD (Leaser Diode) in which music or moving images are recorded.
By using sc) and connecting a display device, a speaker, and an input device instead of the browsing terminal device, music and moving image services can be provided.
