摘要:
The present invention is intended to solve a problem which may be encountered during a transfer from a mode for searching a desired still image to a mode for performing actual reproduction during the process in which still image information is reproduced from a tape-shaped recording medium on which a multiplicity of helical tracks are formed for one picture of still image information, one picture of still image information and address information indicative of the number thereof being recorded in the multiplicity of helical tracks. The sensation of an operator can be made coincident with an actually reproduced still image, for example, by effecting such mode transfer by detecting and using a number adjacent to a desired still image number or by shifting the tape-shaped recording medium by a predetermined amount. Accordingly, it is possible to to search a desired still image rapidly and easily.

A dust collection device for a concrete cutter includes a suction duct disposed on an upstream-most side; a plurality of dust collectors of a cylindrical cyclone system disposed in series downstream of the suction duct; and a plurality of dust collection chambers connected respectively to the plurality of dust collectors and storing individually dust separated in each of the dust collectors. A blower is disposed between any two of the plurality of dust collectors and performs intake and discharge of air by rotation of a built-in fan. A return flow channel communicates the suction duct with the dust collection chamber which is connected via a connection portion to a dust collector disposed on a downstream-most side from among the plurality of dust collectors, or a return flow channel communicates the suction duct with the connection portion.

An engine stop switch and a fuel open-close lock are accommodated in a throttle lever case so that they can be easily disassembled, and the engine stop switch is turned on and off and the fuel open-close cock is opened and closed adequately by the actuation of a rotary valve in response to the turning of a lever. An engine stop switch and a fuel open-close lock are integrally incorporated in a throttle lever case, a partially toothless driven gear is intermittently rotated via a partially toothless drive gear rotated by a lever, and the intermittent rotation of the partially toothless driven gear turns on/off the engine stop switch and opens/closes the fuel open/close cock.

In an image signal recording system for recording on a recording medium an original image signal corresponding to an original picture which is comprised of a plurality of pixels, the original picture is divided into a plurality of pixel blocks each consisting of a predetermined number of pixels, and image signals each corresponding to the associated pixel block divided are recorded on the recording medium in accordance with a first recording mode and a second recording mode which are mutually different in a recording format. Either of the first and second recording modes is selected on each of the plurality of pixel blocks and a recording mode information signal corresponding to the selected recording mode is generated. There are recorded on the recording medium, the first image information signal or the second image information signal formed and the recording mode information signal generated, on a multiple basis. Thus, it is possible to provide the image signal recording system capable of efficiently recording image signals while suppressing a deterioration of the image quality.

A photographic optical system and a viewfinder are disposed above a recorder casing for recording a signal obtained by photography. The photographic optical system and the viewfinder are disposed so as not to overlap each other in a direction parallel to an optical axis of the photographic optical system and so that an optical path of the photographic optical system and an optical path of the viewfinder overlap each other as viewed on an extended line of the optical axis of the photographic optical system. In addition, the photographic optical system is disposed above the recorder casing, and the recorder casing is arranged to eject downward a recording medium for recording of a signal obtained by photography. A grip is disposed on one side of the aforesaid recorder casing, and an operating part for driving a mechanism for varying the magnification of the photographic optical system is provided at the rear of the photographic optical system.

In an encoder/decoder, a quantizer quantizes input image information, and a coefficient generator generates coefficient information for determining quantization steps of the quantizer. An encoder variable length encodes the quantized image information, and a divider divides the quantized image information into a plurality of blocks. The coefficient information is attached to each of the plurality of blocks for transmission to a decoder.

A video signal recording apparatus includes a memory for storing a one-picture portion of an input video signal. An overlapping device gradually switches a first video signal, read from the memory, to a second video signal during a first predetermined time period, and provides an output video signal. A recording device records the video signal output from the overlapping device. A first manual operation member sets the video signal recording apparatus to an overlap mode, in which the overlapping device is operated in response to a start of recording by the recording device. A second manual operation member sets the video signal recording apparatus to an interval recording mode, in which the recording device is periodically operated to record during every second predetermined time period. A determination device determines the first and second predetermined time periods such that the second predetermined time period is longer than the first predetermined time period when the video signal recording apparatus is in the overlap mode and in the interval recording mode.
