A package structure prevents an optical sheet from being brought into contact with a display panel and making scratches on the display panel due to motion caused during transport of a display device, thereby minimizing cost increase. A package structure for a thin display device is the structure for storing the thin display device in a package case. The thin display device includes at least one optical sheet situated in approximately parallel with its display surface, and the package case includes a storage member for holding a thin display device with the optical sheet having a surface inclined relative to a vertical direction.

Package structure for display device

In a photographic processing system for processing a photographic film for each order without splicing it to other photographic film, a destination of each of plural photographic films having a different destination from each other is determined based on photographic film destination determining information recorded on a photographic film to be processed.

Photographic processing system

An apparatus for accommodating a photographic document comprises a web member; a first roller to which one end of the web member is fixed; and a driving force transmitting means for rotating the first roller to wind up the web member thereon so that the photographic document is wound around the first roller together with the web member.

In a spread spectrum communication system for communicating data by spreading spectrum, thereof, using PN codes, on the transmitter side, a first modulated output portion, which is spread-spectrum-modulated, containing no data to be transmitted and a second modulated output portion, which is spread-spectrum-modulated, following the first modulated output portion and containing data to be transmitted are generated; and the second modulated output portion is transmitted with a low electric power and the first modulated output portion with a high electric power. On the receiver side, a correlation-demodulated output is generated by correlation-demodulating a received input; and from the correlation-demodulated output consisting of a first correlation-demodulated output portion corresponding to the first modulated output portion and a second correlation-demodulated output portion corresponding to the second modulated output portion the first correlation-demodulated output portion is detected. Further timing signal serving as a reference for an operation on the receiver side is generated, starting from the first correlation-demodulated output portion.

Further timing signal serving as a reference for an operation on the receiver side is generated, starting from the first correlation-demodulated output portion.

A spread spectrum communication device according to the present invention includes a transmitter and a receiver, and suppresses demodulation errors to a minimum value, even if there exit a plurality of narrow band disturbing signals. In the transmitter, a first PN (pseudo noise) code from a fist PN code generator and a second PN code having a delayed phase coming from a shift register are inputted to a multiplexer and switched according to an exclusive logic sum of data and a disturbing signal. The multiplexer output is modulated by a modulator so that it can be transmitted. In the receiver, a correlation output from a correlator is detected by a detector and a detection output thereof is digitalized by a voltage comparator. A correlation pulse thus obtained is applied to two AND gates. Two time window pulses are each applied to two multiplexers nd are switched by a control signal, the outputs of the multiplexers being respectively applied to these AND gates. Pulses from these AND gates are counted by an up-counter and a down-counter in a demodulating circuit to demodulate the data.

A spread spectrum receiver using a convolver controls the level of a reference signal applied to the convolver in response to comparison of a true correlation output and other correlation output of the convolver or, alternatively, in response to the level of received input signal.
