A camera is used with a photo film cassette of a predetermined type. The photo film cassette includes a spool about which photo film is wound. A cassette shell contains the spool in a rotatable manner. A data disk with a bar code is disposed on the spool in a manner readable externally outside the cassette shell for signaling photo film information. In the camera, a cassette containing chamber contains the cassette. A bottom lid closes the cassette containing chamber in an openable manner. A spool drive shaft rotates the spool of the cassette in the cassette containing chamber, the spool drive shaft being connected to the spool set at a first rotational angle when the spool drive shaft has the first rotational angle. An bar code reader reads the photo film information from the data disk rotated in the cassette containing camber. A type determiner section in CPU detects whether the photo film cassette of the predetermined type is loaded in the cassette containing chamber according to the photo film information from the bar code reader. CPU controls operation of the spool drive shaft, CPU rotating the spool drive shaft when the bottom lid is closed, CPU stopping the spool drive shaft to set the spool at a second rotational angle when the type determiner section detects lack of the cassette or existence of a cassette different from the predetermined type.

A camera equipped with a device, for photoelectrically detecting perforations formed in a film margin, which comprises two elements, one of which is disposed in a space with at least one end slope formed between inner and outer film guide rails so as to keep a film traveling across the back of the camera away and isolated from coming into contact with the element.

In a photographic camera, a film cartridge having a roll film rolled around a spool in a cartridge body and a shutter member for opening and shutting a film exit slit is loaded in a cartridge chamber. A chamber lid is mounted on the camera to be swung between an opening position where it opens the entrance opening to the cartridge chamber and a closed position where it shuts the same. A spool pressing member provided on the inner side of the chamber lid pushes an end of the spool of the film cartridge at a predetermined pressure when the chamber lid is closed. An arm member is mounted on the inner side of the chamber lid at one end to be swung about the end away from and toward the chamber lid and urged away from the chamber lid by a spring at a pressure larger than the predetermined pressure. A pressing portion provided on the free end of the arm member pushes the cartridge body inward of the cartridge chamber as the chamber lid is swung toward the closed position while the pressing portion slides on the end face of the cartridge body with the arm member swung toward the chamber lid overcoming the force of the spring so that the pressing portion rests on an arm rest portion away from the cartridge body when the chamber lid reaches the closed position.

A method for compensating changes which would otherwise be produced in a video output signal when the shutter speed exceeds a certain value, even though the same light level of the received image is maintained on the image pickup. In one embodiment, the shutter speed and/or aperture setting are adjusted to compensate. The amplification factor of the output video signal can also be adjusted. In other embodiments, gamma correction is effected separately for each primary color signal to compensate for the changes which affect the color signals in different amounts as the shutter speed is increased.

A multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) transmission and reception apparatus is provided which allows high accuracy estimation of frequency offset, high accuracy estimation of a transmission path fluctuation and high accuracy synchronization/signal detection. A mapping section generates a plurality of OFDM signals. In these OFDM signals, some pilot carriers are assigned to the same carrier position, and orthogonal sequences are assigned to the same time slot in the same carrier position.

A transmitting apparatus and method transmits different modulated signals from a plurality of antennas, and employs a configuration that includes a modulation section that obtains a modulated signal by performing signal point mapping of transmit bits using a signal point arrangement that is divided into a plurality of signal point sets on the IQ plane, whereby the minimum distance between signal points within a signal point set is smaller than the minimum signal point distance between signal point sets; and an antenna that transmits a modulated signal obtained by the modulation section. A signal point generating apparatus generates a first and second symbols to be transmitted by first and second antennas, respectively.

A cleaning apparatus is provided with a cleaning roller that is positioned so as to be in contact with a photosensitive drum, and with a toner layer thickness regulating member that regulates the thickness of a toner layer adhering to the surface of this cleaning roller. The toner layer thickness regulating member is formed by a toner layer thickness regulating roller that rotates in contact with the cleaning roller.

Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

A transmitter apparatus wherein a simple structure is used to successfully suppress the degradation of error rate performance that otherwise would be caused by fading or the like. There are included encoding parts (11—1-11—4) that encode transport data; a mapping part (3304) that performs such a mapping that encoded data sequentially formed by the encoding parts (11—1-11—4) are not successively included in the same symbol, thereby forming data symbols; and a symbol interleaver (3301) that interleaves the data symbols. In this way, a low computational complexity can be used to perform an interleaving process equivalent to a bit interleaving process to effectively improve the reception quality at a receiving end.
