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: 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.

Abstract: An information processing system includes electronic devices each including a display unit, and at least one information processing apparatus including a display unit. The information processing apparatus is able to communicate with the electronic devices via a network. The information processing system includes a first sharing unit configured to cause sharing of display contents of the display unit of a first electronic device of the electronic devices and the display unit of the information processing apparatus; and a second sharing unit configured to acquire, from the first electronic device, information of a second electronic device of the electronic devices that is operating in cooperation with the first electronic device, and cause sharing of display contents of the display unit of the second electronic device and the display unit of the information processing apparatus based on the information of the second electronic device.

Abstract: A multi-function apparatus includes a basic memory, a socket, and a controller. The basic memory includes at least a first image memory area for a copying function and a second image memory area for a facsimile function. The socket connects an add-on expansion memory. The controller arranges memory assignments of the basic memory in accordance with a first memory map to perform operations of the copying and facsimile functions when the expansion memory is not mounted to the socket. The controller rearranges the memory assignments of the basic memory and of the expansion memory with an effect of expanding the first and second image memory areas in accordance with a second memory map to perform the operations of the copying and facsimile functions when the expansion memory is mounted to the socket.

Abstract: A communication terminal includes a FAX transmission unit, a network FAX transmission unit, an address book, an option setting unit, and a control unit. The address book is adapted to register for each of one or more destinations a FAX number and an e-mail corresponding to the destination. The option setting unit sets a predetermined option for the FAX transmission unit in connection with registration of the FAX number in the address book. The control unit makes the option effective when the e-mail address is used by the network FAX transmission unit.

Abstract: A communication terminal apparatus includes a plurality of electronic mail receiving systems respectively receiving electronic mail from mail servers each connected to a different network and an electronic mail receiving interval setting system for setting electronic mail receiving intervals each indicating respective time intervals for accessing electronic mail from the respective networks, each electronic mail receiving interval capable of being set to different values depending on the type of network.

Abstract: A facsimile relaying method transmits common picture information to a plurality of facsimile receivers designated by a facsimile transmitter, by once storing transmit picture information in a picture store of a relaying apparatus and then sequentially sending it out to the receivers. If a telephone number of any of the designated receivers does not include a toll number, a toll number included in the telephone number of the transmitter is added to the telephone number of the transmitter. If the toll number of the telephone number of the receiver is identical with the toll number of the relaying apparatus, the toll number is omitted from the telephone number of the receiver.
