Abstract: If there is an address input, a setting determining section checks whether or not a Bcc flag is on. Next, the setting determining section determines that a first address is set to a field [To:]. While, the setting determining section determines that addresses including and after a second address are set to a field [Bcc:]. Next, a header generating section describes the first input address in the field [To:] of a mail header. The addresses including and after the second address are described in the field [Bcc:] of the mail header. Next, the mail header generated by the header generating section and a TIFF file text-coded by a text coding section are combined with each other by a combining section, so that an e-mail is generated. As a result, the large number of addresses is automatically allocated to the fields [To:] and [Bcc:].

Abstract: A data communication apparatus includes a communication section that performs a pre-communication protocol and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When data corresponding to a destination terminal data is stored in the memory, a controller performs the pre-communication protocol with the destination terminal, using the stored communication parameters corresponding to the destination terminal. When a communication error occurs in a communication with a particular destination terminal having data stored in the memory, a memory controller deletes communication parameters corresponding to the particular destination terminal from the memory.

Abstract: An image forming apparatus is provided including a power supply that supplies an electric power equal to or less than a predetermined amount of the electric power, a first function that is a process before a printed paper is obtained and uses a first electric power, a second function that is a process performed after the printed paper is obtained and uses a second electric power, and a controller. When the first function and the second function are instructed to be processed in parallel, the controller compares a sum of the first electric power and the second electric power with the predetermined amount of the electric power. When the sum of the first electric power and the second electric power exceeds the predetermined amount of the electric power, the controller delays one of the first function and the second function.

Abstract: A tray body 2 and a movable plate portion 10 can be folded each other. If there is sufficient space in an apparatus setting area, the movable plate portion 10 is opened, and cut paper is support by both a first mounting surface 3a and a second mounting surface 10a. If the apparatus setting area is limited, the movable plate portion 10 is closed and the occupying area of a feeder tray 1 is reduced. In this case, since an insertion port 16 is formed between the first mounting surface 3a and the second mounting surface 10a, paper feeding can be carried out even when the tray body 2 and the movable plate portion 10 are folded.

Abstract: A data communication apparatus includes a communication section that performs a pre-communication protocol with a destination terminal and transmits data to a destination terminal. A memory stores data and communication parameters corresponding to each destination terminal, the communication parameters being utilized to perform communication with the destination terminal. When destination terminal data is stored in the memory, a controller reads the communication parameters corresponding to the destination terminal from the memory, performs the pre-communication protocol with the destination terminal, using the read communication parameters, and omits at least a communication protocol for line probing.

Abstract: A multifunctional printer retains image data in an image memory when paper runs out during a copying operation, until another operation is requested or a predetermined time period expires. Also, the multifunctional printer retains information of the document that has not been recorded in a RAM when erasing the image data.

Abstract: A mail retrieval moderator instructs an image memory usage rate calculator to calculate a usage rate of an image memory, and determines whether the usage rage is greater than or equal to 98%. When the answer is “Yes”, there is a risk that the image memory will have a memory overflow if more e-mail is retrieved from the POP3 server. Thus, a timer is reset and the control returns to ST501. When the answer is “No”, there is no risk that the image memory will have a memory overflow even if more e-mail is retrieved from the POP3 server. Thus, e-mail is retrieved from the POP3 server. Accordingly, the apparatus and method for receiving e-mail is capable of securely retrieving e-mail from the mail server, even with a relatively small memory capacity.

Abstract: A facsimile communication system, having a hierarchical system, comprises a central service center as the highest hierarchy, several local service centers as an intermediate hierarchy, plural facsimiles as the lowest hierarchy. The central service center manages the local service centers and fax via the local service centers through a telephone network by the pictorial communication and data communication. A user of a facsimile fills up a support service application by marking YES/NO or wiring desired data. The central service center receives the application and inputs the data to store and send the data to a local service center in charge of the facsimile.

Abstract: The communication terminal apparatus according to the present invention comprises a determination section for checking whether or not a dial key is pressed. If a dial key is pressed, the determination section checks whether the “dial key/browser dual-function” flag in the setting table is ON or OFF. If it is ON, the determination section checks whether the “focus HTML input field” flag is ON or OFF. If it is ON, the determination section determines that the input data of the dial key be subjected to browser input processing. On the other hand, if the “dial key/browser input dual-function” flag is OFF, this determination section determines that the dial key be used for dial input processing.

Abstract: A relaying apparatus relays an E-mail to a facsimile destination. The relaying apparatus stores a non-public mail address, which is accessible only by an authorized sender having authorization, and a public mail address, which is accessible to a sender regardless of authorization. A receiver receives the E-mail via a network, a recognizer recognizes a destination address from the received E-mail, and a determination section determines whether the recognized destination address is the non-public mail address or the public mail address.

Abstract: In the case that a PC sends a call to a called site on a telephone line network, but fails in its connection, the PC and a modem of a facsimile apparatus are connected. Then, the telephone number and image data of the called site are stored in a RAM of the facsimile apparatus. After storage is completed, the telephone line network and the modem of the facsimile apparatus are connected. Then, a call is sent to the called site and the image data is sent to the called site. This allows connection to be made to the PC without using a dedicated interface and prevents burdening on the PC in redialing in the case that there is no answer from the called site.

Abstract: Various kinds of modem control information is stored for each destination, the modem is operated based on stored various kinds of control information to shorten a communication pre-protocol and transmit data when execution is carried out. Also, when a short previous-procedure does not normally proceed, communication is shifted to a second communication procedure whose speed is low so as to continue communication after a lapse of a predetermined period of time. When abnormality occurs after executing the short previous-procedure, various kinds of control information stored in memory means are erased and up-dated. Therefore, time for communication preprotocol is shortened, and a mounted short previous-procedure function appropriately operates even when a communication error rate is high or a line characteristic is changed.

Abstract: A data communication apparatus such as a facsimile apparatus having an automatic telephone message recording function, having a common memory for storing video and audio data that have been received or are to be transmitted, enables selection of a method of memory management whereby the memory space is divided at a boundary address into two regions which respectively store video data and audio data and a method whereby the memory space is not so divided, but the video data and audio data are written into addresses which successively increase from respectively opposite ends of the memory space. Remaining amounts of memory capacity which can be used to store video and/or audio data can be displayed as respective numbers of standard document pages and telephone calls, the latter representing standard-duration recording intervals.

Abstract: When characters are input, the input information is sequentially displayed on a first display, an e-mail address, which is registered in a one-touch key registration area, is retrieved by using the input information, and the retrieved e-mail address is displayed on a second display. Further, when an @ mark is input after a character string input, the information displayed on the second display is switched to a domain name read from the domain name registration area. Thus, the @ mark key, which is always used to input e-mail addresses, is also utilized to switch the display information. Accordingly, the data communication apparatus is capable to prevent the inconvenience of inputting the entire e-mail addresses and to prevent input errors.
