In an optical disc having an RFID tag, disc control information needed for control of reproduction of the content recorded in the disc body of the optical disc is stored in the RFID tag. Thereby, even if the content recorded in the disc body is illegally copied in some way, common optical disc apparatus incapable of reading RFID tags cannot read and copy the disc control information stored in the RFID tag. Accordingly, unauthorized copying of the content recorded on the optical disc can be reliably prevented without the use of special cryptographic technology.

An image, in which a pattern image is arranged so as to express a control information for inhibiting copying or for removing the inhibition, is defined as an image to be read. A copy inhibition code or a condition code for removing the inhibition is assigned for the pattern image. In a "normal copy mode" of a copier, a copy inhibition information detecting part detects the copy inhibition code in an obtained image, and a controller halts the copying when the copy inhibition code is detected. A condition information detecting part detects the condition code in the obtained image. A copy mode is provided in which the copying operation is permitted when the condition matches. The controller permits copying when a condition, such as permitting a specific user to perform copying or the elapse of a predetermined day and time delimited period, is established.

In a shop POS register terminal, a settlement request-generating unit generates settlement request information, which includes an amount of settlement. A request barcode is generated from the settlement request information, and the POS register terminal displays or prints the information. In a cell phone, the camera restores the settlement request information through the request barcode image. The amount of settlement is subtracted from a value charged to an IC chip. Settlement response information is generated, which includes the balance after settlement of the IC chip. Then a response barcode is generated from the settlement response information, and causes the cell phone to display the same. In the POS register terminal, the response barcode is read out to restore the settlement response information. Then an IC card settlement-ending unit confirms and causes the POS register terminal to print the receipt.

Gate switches can switch an amount of attenuation, and are set in a distributed manner on distribution lines and a trunk on subscribers' house side in a CATV transmission path having a tree structure with an optical node that follows a headend being taken as a starting point. An upstream-transmission-quality monitoring unit monitors an S / N ratio of an upstream signal obtained from an upstream port having the headend connected thereto to detect a decrease in upstream transmission quality based on a degree of decrease and a continuation state of an S / N ratio. When the upstream-transmission-quality monitoring unit detects a decrease in upstream transmission quality, a noise-generation-source searching unit performs a sequential switching control over the amount of attenuation at the gate switches provided on the CATV transmission path from upstream to downstream to search for a source of generation of upstream ingress noise.

When a user sets water power using a water power adjustment switch in a remote control device, a controller controls the period of pressure fluctuations, the width of pressure fluctuations, and the central pressure of the discharge pressure of a pump on the basis of a signal transmitted by radio from the remote control device. When the user sets the divergent angle of washing water using a washing area adjustment switch in the remote control device, the controller controls the divergent angle of the washing water sprayed from a posterior nozzle on the basis of the signal transmitted by radio from the remote control device. Consequently, the washing water supplied to a side surface of a cylindrical swirl chamber from a first flow path in the posterior nozzle is sprayed from a spray hole as dispersed spiral flow, and the washing water supplied to a lower part of the cylindrical swirl chamber from a second flow path in the posterior nozzle is sprayed from the spray hole as linear flow.
