Abstract: An encoder signal processing device, a printer, a printer-equipped imaging apparatus, and an encoder signal processing method that can remove the effect of a noise signal mixed with an encoder signal and favorably deal with a case where an original pulse signal is lost from the encoder signal are provided. An effective detection period setting unit 523 sets an effective detection period for detecting a subsequent pulse signal, each time a pulse signal detection unit 522 detects a pulse signal from an encoder signal. The pulse signal detection unit 522 detects the pulse signal only within the set effective detection period. In a case where the pulse signal detection unit 522 does not detect the pulse signal within the effective detection period, a pulse signal generation unit 524 generates the pulse signal after the effective detection period.

Abstract: A pulse signal is detected from an encoder signal of a rotary encoder. The detected pulse signal is used as a signal for controlling a light exposure timing of a line type light exposure head and is used for detecting a transport speed of an instant film. The light exposure head sequentially performs light exposure for a line image on the transported instant film in synchronization with each pulse signal detected from the encoder signal, and a density correction unit corrects an amount of light emission of the light exposure head depending on the transport speed of the instant film.

Abstract: A lens-fitted photo film unit is preloaded with a roll of photo film whose film speed is ISO3200, and has a mode selection member that is manually operated to select one of a standard photography mode, an indoor photography mode and a night-view photography mode. In the standard photography mode, an exposure is made without flash with a small aperture size and at a high shutter speed. In the indoor photography mode, an exposure is made with a flashlight, with a middle aperture size and at a high shutter speed. In the night-view photography mode, an exposure is made with a flash light, with a large aperture size and at a low shutter speed.

Abstract: A mode selection member is moved to the lowest position for selecting a daylight mode, which is most frequently used, the middle position for selecting a middle mode for photographing outdoors under the overcast sky, or the highest position for selecting an indoor mode for photographing indoors. When the mode selection lever is in the middle position or the highest position, the upper end of a mode indicating plate protrudes from a unit body. When the mode indicating plate is pushed down into the unit body, the mode selection lever is forced to return to the lowest position to set the daylight mode.

Abstract: A lens-fitted photo film unit is not provided with a flash device. A photo film having ISO sensitivity of 1600 or above is preloaded in the lens-fitted photo film unit in a factory. An exposure device has a large-exposure amount mode and a small-exposure amount mode. In the large-exposure amount mode, appropriate exposure can be given to a subject when an exposure value at ISO 100 is less than 8. A mode switching operation member selects the large-exposure amount mode or the small-exposure amount mode.

Abstract: A lens-fitted photographic film unit is provided with a cassette chamber for containing a cassette and a film chamber for containing an unexposed photo film drawn from the cassette. The front portion of the cassette chamber is formed of a curved wall which cross section is in a U-shape. A taking lens has a first lens element, a second lens element, and a third lens element that are disposed from the subject side in the stated order. A shutter blade is provided with a light shield portion for opening/closing a photography light path. The light shield position is disposed between the first lens element and the second lens element, such that a part of the light shield portion enters a space formed in front of the cassette chamber when the shutter blade moves from a close position to an open position.

Abstract: In a lens-fitted photo film unit, a photo film is preloaded in the factory. The lens-fitted photo film unit includes a flash device for emitting flashlight from a xenon lamp by a discharge current of a main condenser. The flash device has guide number in the range from 2 to 5, and the color temperature of flashlight is in the range from 4500K to 5000K. The capacitance of the main condenser is from 8 ?F to 10 ?F.

Abstract: Disclosed is a lens-fitted photographic film unit containing a roll of unexposed photographic film. The lens-fitted photo film unit uses a specific battery of a different size or shape from conventional standardized batteries. A hollow protrusion is formed in a battery holding room. A hollow of the hollow protrusion joins with a dark room for the photographic film. If the hollow protrusion is cut away with the intention to put a conventional battery in the battery holding room, the light-tightness of the dark room is destroyed. When a cartridge chamber bottom lid is opened to remove a film cartridge, an interconnection lever transmits the opening movement of the lid to a sliding plate. Then the sliding plate turns a charge switch of a flash circuit ON, and locks the charge switch in the ON position.

Abstract: A lens-fitted photo film unit is pre-loaded with photo film, and is a flash built-in type. A booster circuit boosts power source voltage to obtain high voltage. A main capacitor stores charge at the high voltage. A flash discharge tube is connected with the main capacitor, and emits flash light by discharge at the high voltage. A trigger circuit triggers the discharge of the flash discharge tube in response to an exposing operation. A main circuit board has the booster circuit and the trigger circuit mounted thereon. A subsidiary circuit board is connected with the main circuit board, and has a flash quenching circuit mounted thereon. The flash quenching circuit operates in an auxiliary manner, and automatically adjusts the amount of the flash light.

Abstract: By pushing down a shutter release operation member (9), that is mounted on a front of a waterproof case of a waterproof type lens-fitted photo film unit, a release lever (70) is caused to rotate through a rotary shaft (71) that is put through a front wall of the waterproof case. Thereby, the release lever directly pushes an arresting member (59) through an opening (19c) provided on a front side of a unit body (3), releasing a shutter drive member (51) as having been arrested in a cocked position by the arresting member (59), and thus causing a shutter blade (45) to make an open-close movement. The waterproof case consists of a pair of case members that are put on the unit body from its front and rear sides, and are joined to each other by engagement. An elastic waterproof ring is force-fitted in a gap of the joint between the case members.

Abstract: A first light guide and a second light guide are attached to a flash charge switch. Each light guide is arranged in a direction where the flash charge switch is slid. If the flash charge switch is in an OFF position, the first light guide transmits light from a photometric window to a photo sensor. If the flash charge switch is in an ON position, the second light guide transmits the light through the photometric window to the photo sensor. As the first light guide has a short distance from an incident end to the photometric window, the incident end has a large incident angle and brighter light is transmitted to the photosensor. As the second light guide has a long distance from the incident end to the photometric window, weak light is transmitted to the photo sensor. When an output signal of the photo sensor is above a predetermined value, a solenoid is activated to set a stop plate on a photographic light path. The stop plate is formed with a small stop aperture.

Abstract: Photo film has plural perforation sets arranged along one edge thereof in line at a regular pitch. Each of the perforation sets includes first and second perforations, which are arranged closely at a regular distance. A sprocket wheel is rotated by movement of the photo film. The sprocket wheel has a wheel body. Two tooth sets respectively include first and second teeth, are disposed to protrude from a peripheral face of the wheel body, and are respectively meshed with the first and second perforations serially. An arm is disposed on the peripheral face of the wheel body, for frictionally contacting a portion of the photo film between first and second perforation sets, to be rotated by the photo film. The first and second perforation sets are included in the plural perforation sets and adjacent to each other. Each of the tooth sets are meshed with the second perforation set after being disengaged from the first perforation set.
