A noise cancellation unit includes: a duct connected to an outlet of an electronic apparatus and configured to pass an exhaust flow discharged from the outlet therethrough; a first microphone provided to the duct; a speaker provided to the duct downstream of the first microphone; a second microphone provided to the duct downstream of the speaker; a first windscreen wall configured to prevent the exhaust flow from colliding with the first microphone; a second windscreen wall configured to prevent the exhaust flow from colliding with the second microphone; and a signal processing circuit configured to generate, based on outputs of the first microphone and the second microphone, a sound signal for removing a noise included in the exhaust flow and supply the sound signal to the speaker.

In a camera system of this invention, a light beam coming from a photographing lens is reflected by a quick return mirror in the widthwise direction of a body unit, and is reflected by a second mirror via a half mirror and screen in the upward direction of the body unit except for some light beam components. The light beam reflected by the second mirror is reflected by a third mirror in a direction opposite to that of the light beam reflected by the quick return mirror, and is also reflected by a fourth mirror toward an eyepiece side in the back side of the body unit. Some light beam components reflected by the half mirror are fetched by an AF sensor unit to detect the focal point position of the photographing lens.

A flood light includes a lamp that is located at a focus of a reflecting mirror having a reflecting surface whose cross-section is oval and partially arcuate. A concave lens having negative refracting power is disposed between first and second foci about which an elliptical reflecting surface of the reflecting mirror is disposed. Some light rays from the lamp pass directly from the lamp through the lens while other rays from the lamp are reflected by the mirror before passing through the lens. Generally speaking, on the upstream side of the lens, the reflected rays enter the lens outboard of the rays that pass directly from the lamp to the lens. This construction provides a small flood light that has a high optical output, and effectively uses bundles of rays emitted from the lamp to produce a luminous intensity distribution desirable as light for range finding.

Light from a flash discharge tube is reflected in a forward direction by a concave mirror and further refracted to a negative direction by a projection lens. A trigger wire for triggering the flash discharge tube to set off emission is constructed of an elastic material. The flash discharge tube is retained, as an integrated combination, by a discharge tube mounting frame on which support axial parts are provided in a protruding manner, and these support axial parts are slidably and swingably fitted with slide slots of the casing which are provided along the optical axis, so that the flash discharge tube is arranged to be displaceable both in a direction of the optical axis of the flash light emission apparatus and at least in one direction in a plane perpendicular to the optical axis with respect to a relative position thereof to the concave mirror.

In an imaging apparatus capable of continuously capturing images, the captured images are displayed sequentially to allow a user to select a desired image and record the selected image on a recording medium. This can prevent the recording of unnecessary images on the recording medium, making effective use of the memory space.

A light projector for camera including a light emission lamp having a filament, a lamp mounting frame which holds the light emission lamp integrally therewith as well as has a pair of support shafts projecting from opposite the sides thereof with one of the support shaft having a rectangular hole defined thereto, a reflection umbrella for reflecting the light from the filament, a light projection lens disposed so that the optical axis thereof matches the optical axis of the reflection umbrella and a casing on which the reflection umbrella and the light projection lens are mounted, wherein the lamp mounting frame is held by swingably engaging the pair of support shafts and the like with a pair of sliding grooves and the like along an optical axis direction. The relative position of the filament to the reflection umbrella can be displaced in the optical axis direction, an up/down direction and a right/left direction merely by inserting a single jig into the rectangular hole and applying displacing force thereto, whereby the dispersion and the like of the position of the filament can be corrected by a simple adjustment job so that an effective ratio of light can be increased.

In order to effectively and rapidly prevent, by use of a dustproof unit inside an image pickup unit, dust that has an adverse effect on the pickup of input images from sticking to optical members and to improve assembly for a simpler configuration, in an image pickup apparatus, a dustproof unit comprises a dustproof filter capable of vibrating in front of the image pickup device to prevent the dust from sticking to the image pickup device, an electrostrictive element for vibrating the dustproof filter, a flexible printed board on which there is mounted at least a drive circuit to drive and vibrate the electrostrictive element, and a support table provided with the flexible printed board, the electrostrictive element and the dustproof filter, and this dustproof unit is mounted in an image pickup unit in consideration of the assembly.
摘要:
In optical equipment, an image pickup element is not electrically connected directly to a hard electric board, but is electrically connected thereto via a flexible printed circuit. Since the image pickup element and the hard electric board are electrically connected via the flexible printed circuit, thermal effect of soldering or effect of deformation of the hard board can be alleviated. Since the flexible printed circuit has flexibility, the image pickup element can easily be positioned at an accurate position at the time of assembly. Also, it can hardly be affected by aged deformation.
