A compact image input apparatus is operable under low power consumption, while omitting a buffer memory for storing image data, which is originally required to transfer image data between this image input apparatus and a personal computer. The image input apparatus is arranged by an image sensor for optically sensing an image of an object to produce an analog image signal; an A/D (analog-to-digital) converter for A/D-converting the analog image signal derived from the image sensor into a digital image signal; an interface control unit for converting the digital image signal derived from the A/D converter into image data; an image sensor driving unit for driving the image sensor; an A/D converter driving unit for driving the A/D converter; a clock oscillator for oscillating a clock signal; a clock switching control unit for controlling a supply of the clock signal to the image sensor driving unit and the A/D converter driving unit in response to the clock signal produced from the clock oscillator, and both a transfer starting signal and a transfer clock signal supplied from the interface control unit; and a personal computer for receiving the image data converted by the interface control unit and for supplying the transfer starting signal to the interface control unit. The clock switching control unit includes drive means for supplying the clock signal produced form the clock oscillator to the image sensor, and also for not supplying the clock signal to the A/D converter driving unit within a preset time period after the transfer starting signal is received.

The image scannercomprises a manuscript conveying unithaving conveying rollsfor conveying a manuscriptand a first light source, and a manuscript reading unitmounted on the manuscript conveying unit. The manuscript reading unitdetects movement of the manuscriptin the sub-scanning directionby a rotation detecting rolldriven by the conveying roll. When the manuscriptis a reflection-type one, only a second light sourceis switched ON to read the manuscript. When the manuscriptis a transmission-type one, only the first light sourceis switched ON to read the manuscript. The image scannerdoes not have a fixed platen. One-dimensional CCDis fixed. The image scannercan therefore be small in size.

Compact image scanner capable of reading both a light-reflecting article and a light-transmitting article

An apparatus for a printed character reading system in which prior to the recognition process, the information obtained by reading the characters on a source document is separated line by line to obtain a line information and then, starting at its one end, the line information is successively separated character by character to obtain a character information for each of the individual characters. In this apparatus, the read character information is stored primarily character by character each for approximately one and a half line width and the 1.5-line information is then dissected in the line direction into blocks each having a line length of two character spacings. Then, a linewise projection information is produced for each of the blocks so that in accordance with the resulting projection information the intended line information is separated into blocks and then the character information for the respective characters are separated successively from the character information contained in each of the blocks.

A cartridge/carrier locking device for an automatic gun including a latch plate pivotally mounted on an inner wall of a receiver to pivot in a seesaw like manner to have two ends thereof alternately protrude inside of the receiver. The front end protrudes to restrain a cartridge and the rear end to restrain a carrier. A spring pushes the rear end toward the inside of the receiver. Against this spring, a breechblock and a cartridge brought out of a magazine respectively restrict the protruding motion of the rear end until the breechblock moves backward approximately to a maximum extent. The position at which the breechblock comes to restrict the protruding motion of the rear end of the latch plate is arranged to differ from the position at which the cartridge comes to restrict in such a way as to allow the rear end to lock the carrier.

Cartridge/carrier locking device for automatic gun

In an automatic gun, the gas pressure generated by the firing of a shot shell is transmitted to the breechblock in the receiver housing by the axial sliding movement of an action bar assembly mounted outside the gunbarrel or the cartridge magazing tube for releasing the breechblock. The action bar assembly includes action bars slidably mounted coaxially with each other and an adjusting spring for arresting the contraction of the span between the stem bodies. A cylinder is fixed to the gunbarrel for receiving the gas pressure from it. The forward end of the action bar assembly extends into the cylinder, while the rearward end passes through a guide hole in the receiver into contact with the front surface of the breechblock. The rearward end has a stopper for restricting the axial movement of the action bar assembly to a predetermined length. A supporting mechanism serves to arrest the rotation of the gunbarrel and the fore-arm by engaging a projection of a predetermined shape, provided at the forward end of the receiver, with cutout portions in the outer periphery of the gunbarrel and the fore-arm.

A trigger device for automatic gun provided with a connector piece which serves to engage a hammer with a sear and also is interlocked with a trigger to slide forward on a trigger guard inside a receiver in such a way as to disengage the hammer from the sear in direct response to the backward and forward movement of a breech block.

A cartridge/carrier locking device is used for an automatic gun loading arrangement of a type for removing a cartridge from a magazine onto a carrier by releasing it from a locked state for firing and for pushing it up into a barrel chamber by an upward sway of the carrier which takes place in response to the forward stroke of a breech block. A latch plate which is provided with a first claw part at its forward end for locking the cartridge and a second claw part at its rear end for locking the carrier, is pivotally attached to an inner wall of a receiver containing the automatic gun loading arrangement. The first and second claw parts serve, respectively, to lock the cartridge and the carrier as the claw parts alternately protrude into the inside of the receiver in a swaying fashion. A spring is arranged to push the second claw part of the latch plate to the inside of the receiver. A locking part is also arranged at the rear end of the latch plate and engages with the breech block, the carrier and the cartridge to restrict the swaying motion of the second claw part into the inside of the receiver so that the engagement is released allowing the second claw part to act and to release the first claw part from its action only when a retracting stroke of the breech block comes to exceed to preset value after the gun is fired.

A firearm cartridge assembly consists of a casing having a bullet mounted in one end and an explosive charge in the opposite end with a wad extending between the two end elements. The wad has a generally cylindrical configuration and includes a first end and a second end each containing a similarly shaped recess. The first end in the assembled position contacts the explosive charge and the second end contacts the trailing end surface of the bullet. Located between and spaced axially from the ends of the wad is a centrally located disc-shaped section extending transversely of the axis extending between the ends and having an outer periphery generally conforming to and in surface contact with the inner surface of the casing so that the disc-shaped section forms a seal with the casing against gas leakage when the charge is exploded. In addition, spring sections, compressible in the axial direction of the casing, are located one between the first end and the disc-shaped section and the other between the opposite side of the disc-shaped section and the second end. Preferably the wad is integrally formed from a plastic material and it is symmetrical on the opposite sides of the disc-shaped section.
