Abstract: A plurality of virtual client processes for accessing a server are simultaneously operated on test execution terminal, when accessing the server by each virtual client process, respectively unique virtual network addresses are set, a source network address in a transmission packet is rewritten into the set virtual network address from an actual network address, a destination network address in a reception packet from the server is rewritten into the actual network address from the virtual network address, and this packet is transferred to the client with this virtual network address set therein. Load tests of accesses to the server from a multiplicity of client terminals can be executed by a small number of test terminals without depending on network protocols.

Abstract: A terminal apparatus is capable of efficiently managing the status of shared device(s) on the network in a unified manner, constantly, with the latest status information, thereby permitting a user easily to understand the status of the desired shared device. For each of the terminal apparatuses on the network, there are provided server and client. These function in the same manner regardless of whether the information exchange is with another apparatus or within one apparatus. The server means acquires and provides the information of the shared device, required from the client of another apparatus or the same apparatus.

Abstract: By comprising a unit for designating a distribution destination on a network, unit for specifying data to be distributed to the designated distribution destination, unit for determining a distribution method for distributing the specified data, and unit for distributing the data to the designated distribution destination based on the determination, data is appropriately distributed by selecting a distribution method which is suitable to the amount of data to be distributed and the setting state of the network of the distribution destination.

Abstract: It is an object of this invention to allow a user to perform operations while he or she is unconscious of the types of interfaces of various image input devices on a network. An image input server device on a network is searched for, device control information of an image input device locally connected to the found image input server is obtained from the server, and virtual device information based on a universal image in-out interface is generated from the obtained device control information. An image reading session is executed in collaboration with the image input server device by using the virtual device information and information of communication with the image input server device. An image input server device to which an image input device is locally connected receives a session request from a client on a network and determines the type of requesting client from the session request.

Abstract: Environments of various devices such as an image input device are effectively used as a commonly used resource (shared resource) on a network can be simply set without any loss. In an information processing apparatus provided on a network, a CPU checks as to whether or not a device is locally connected to this information processing apparatus, and then notifies this check result to a management device provided on the network. This management device judges as to whether or not a server program of a common system is installed in a terminal apparatus based on a content of a notification issued from this terminal apparatus. In accordance with this judgement result, the management device installs this server program to this terminal apparatus.

Abstract: The present invention relates to a recording paper winding apparatus for winding a recording paper on a rotary drum, by providing a bar for pinching a front end of a recording paper between the bar and the outer surface of a rotary drum, whereon a recording paper is to be sucked by making inside a negative pressure. Thus, the recording paper can be wound on the drum by a simple operation and held tightly thereon.

Abstract: A separation mechanism part is provided wherein a negative pressure to suck a recording paper apart from a stack is obtainable by contacting an uppermost sheet of the recording paper using a suction head, air flow into the suction head being cut off by contact of the suction head with the first sheet of the recording paper. The recording paper is sucked and separated one sheet by one sheet by bringing up the suction head, as such, by the negative pressure. This paper feeding apparatus can feed recording paper surely separated sheet by sheet, and even though the amount of piling of the recording paper in the piled state changes, the separating force applied to act on the uppermost sheet of recording paper when suction is applied is kept small and uniform.
