Abstract: A billing system includes an operation unit, a determination unit, an extraction unit, a first calculator, and a second calculator. The operation unit receives an operation for executing a function provided by one device of a plurality of devices. The determination unit determines whether the one device is available for the function associated with the operation received by the operation unit. The extraction unit extracts another device that is available for the function as a substitute for the one device when the determination unit determines that the one device is not available for the function. The first calculator calculates a fee for the function to be executed by the other device. The second calculator calculates a total billed amount based on the fee calculated by the first calculator and content executed by the other device when the function is executed by the other device.

Abstract: A conference system includes a conference server device and a connection control device that are connected with each other via a closed network, the conference server device includes a storage that stores external terminal specifying information containing specifying information from a network other than the closed network, which specifies an external terminal being permitted to connect to the conference server device, and the connection control device includes circuitry configured to transmit control information for connection to the closed network to an internal terminal being connectable to the closed network; determine, when a request for connection to the conference server device is issued from the external terminal, whether the specifying information is contained in the external terminal specifying information; control communications between the internal terminal and the conference server device according to the control information; and permit the communications when the specifying information is contai

Abstract: An operation unit in a child device causes a main unit in the child device to execute a stand-alone job, and causes the main unit and a server device to execute a cooperating job. The main unit executes the stand-alone job every time it is requested, and generates and manages a stand-alone job log including stand-alone job log identification information. The server device controls the execution of stand-alone jobs included in the cooperating job based on a request for executing the cooperating job, and manages cooperating job identification information associated with the stand-alone job log identification information of the stand-alone jobs included in the cooperating job. The server device acquires the stand-alone job logs from the main unit and extracts the stand-alone job logs including the stand-alone job log identification information associated with the cooperating job identification information, to generate a cooperating job log corresponding to the cooperating job.

Abstract: An operating information storing system includes a master apparatus and multiple slave apparatuses. The master apparatus and each slave apparatus respectively include a first processor. The master apparatus includes a nonvolatile memory, the first processor that acquires operating information generated by each slave apparatus, stores the acquired operating information, and determines if at least one operating information indicates specific operating information, and a first transmitter. Each slave apparatus includes a volatile memory, a second processor to store generated operating information in the volatile memory sequentially, and a second transmitter that transfers the operating information stored in the volatile memory to the master apparatus.
