Abstract: By adopting a recycle goods sales system, a user can always use a new machine and dispense with a maintenance operation for a consumable member such as a toner on a user's part. A manufacturer can reduce prices of parts of a host machine by employing common parts and earn profits from options such as a printer interface. Therefore, this invention provides the recycle goods sales system which can promote spreading the electronic equipment article which employs the toner as a consumable member.

Abstract: A network facsimile apparatus, including a LAN interface unit, a facsimile interface unit, a memory unit, and a control unit, transmits image information received as e-mail through a computer network to another facsimile apparatus through a public channel, stores an e-mail address of a backup transmission destination with respect to the facsimile transmission in a memory unit for storing e-mail addresses beforehand. When the facsimile transmission is completed, the network facsimile apparatus generates communication control information and prepares an e-mail message that indicates the communication control information therein to transmit the e-mail message to the backup transmission address stored in the memory unit. Accordingly, a user can easily and readily ensure the result of the facsimile transmission by receiving the e-mail from the network facsimile apparatus.

Abstract: A radio communication system including a plurality of base stations which communicate with a plurality of radio terminals respectively is provided with a capability of avoiding occurrence of radio interference of control channel signals among a plurality of base stations even when a plurality of the base stations are located in the close vicinity of each other. The base station of the radio communication system is provided with a device for receiving, when the power is turned on, a control channel signal which is being transmitted at a certain interval by each of the other base stations in the system, a device for frame synchronizing each of TDMA frames of the control channel signal which is received, a device for extracting base station identification information of each of the other base stations from the TDMA frames which are frame synchronized, and a device for storing in a memory each of the base station identification information which is extracted.
