Abstract

The invention converts information input from either a charge line or a non-charge line to data form and then stores it in a memory device along with identification data specifying the type of line on which the information was received. It also reads information from the memory device in response to information read requests received by way either of a charge line or of a non-charge line and, when called upon to output said information either to a charge line or to a non-charge line, it inhibits the output of the information to a non-charge line in cases where the line indicated by the aforementioned identification data and the line on which the information read request is received are both non-charge lines. This enables either the sending party or the receiving party of a service, but not both, to be charged for the service while at the same time ensuring that, if the sending party and the receiving party of the service both use a non-charge line, the output of the information will be inhibited in order to preserve the integrity of the charging function. Moreover, if the line indicated by the identification data and the line on which the read request is received are both charge lines, a message is sent to the issuer of the read request to indicate the availability of a non-charge line. This prevents the sending party and the receiving party of the same service from both being charged for the service.

Claims

1. An information input/output controller for telephone lines to which is connected a charge line, which incorporates a charging function, and a non-charge line, which does not incorporate a charging function, and which comprises

(a) a memory means for the storage of data,

(b) an input means which converts information input either from said charge line or from said non-charge line to a data format and then writes said data into said memory means along with identification data specifying the line on which said information was received, and

(c) an output means which, on receipt of an information data read request from either said charge line or said non-charge line, reads the requested information data from said memory means and outputs it to said charge line or said non-charge line, while at the same time restricting the output of said information data to said non-charge line in cases where the line indicated by the identification data and the line on which the read request was received are in both cases said non-charge line.

2. The information input/output controller according to claim 1 in which the aforementioned information data is linked both with identification data specifying the telephone line used by a sending party and also with ID specification data and is then stored in said memory means, and in which said output means reads out the information data which corresponds to the ID data input by a receiving party.

3. The information input/output controller according to claim 2 in which said identification data and said ID specification data are both inserted at the head of said information data.

4. The information input/output controller according to claim 2 in which the ID specification data is a personal identification number agreed in advance between the sending party and the receiving party.

5. The information input/output controller according to claim 2 which further comprises

an error message output means which outputs an error message to the telephone line whenever there is a failure to create ID specification data.

6. The information input/output controller according to claim 1 which further comprises

a message output means which outputs a message to the telephone line whenever it receives an incoming signal from a sending party or a receiving party.

7. The information input/output controller according to claim 1 which further comprises

an advice output means which, whenever the aforementioned output means inhibits the output of information to the non-charge line, outputs an advice message to said non-charge line.

8. The information input/output controller according to claim 1 in which the aforementioned telephone lines are connected to personal computers installed on the premises of a sending party and a receiving party.

9. The information input/output controller according to claim 1 in which the aforementioned information data consists of a spoken message.

10. The information input/output controller according to claim 1 in which said information data consists both of basic game software, which is configured such that, in its downloaded condition, it will be erased if a termination operation is carried out, and also of added data which has been input by a user.

11. The information input/output controller according to claim 10 in which said basic software plus added data is configured such that, when the sending party accesses said input means by way of said telephone line, it can be written into said memory means without being erased.

12. The information input/output controller according to claim 1 which is connected both to a plurality of charge lines and also to a plurality of non-charge lines.

13. The information input/output controller according to claim 1 which further comprises

an advice means which, whenever the line indicated by the identification data and the line on which a read request has been received are both charge lines, outputs a message to advise a receiving party who has originated the read request that a non-charge line is available for his use.

14. The information input/output controller according to claim 1 in which said information data consists of a written message.
