Abstract: PURPOSE:To eliminate the problem of the positioning of an original and to attain clear color reproduction faithful to the original by obtaining process signals for polychromatic overprinting from one original through color separation optical systems and specific color separating circuits. CONSTITUTION:Reflected light of light projected on a scanning point on the original from an illumination lamp is separated three primary color light beams of R, G, and B through three kinds of dichroic mirrors which are arranged in sesies, and those light beams are passed through three photodetecting elements and preamplifiers to obtain analog signals AR, AG, and AB of R, G, and B. Those signals are compared with reference voltages RR, RG, and RB by comparing circuits 15R, 15G, and 15B, and their difference signal are passed through inverting gates 16R, 16G, and 16B and inverted into a cyan signal S'C, a magenta signal S'M, and a yellow signal S'Y, which are supplied to an AND gate 17 to output black print process signals. Then, process signals of cyan, magenta, and yellow are obtained from AND gates 19C, 19M, and 19Y with the signal from an inverting gate 18 to reproduce clear colors faithful to the original.

Abstract: PROBLEM TO BE SOLVED: To use up all of ink most efficiently with small heat energy by preheating heat soluble ink, dissolving it once to be retained in an ink retaining body, and heat dissolving it to be transferred in a recording medium. SOLUTION: Heat soluble ink 10 is preheated in a preheating position through the operation of a heater 20, and the part to be heated dissolves to retained once in an ink regaining body. Herein, since the heat soluble ink 10 is held rotatably on a shaft 11, the outer peripheral surface thereof is consumed over the entire circumference. After that, the ink retaining body 30 rotates so that the heat soluble ink 10 moves to the image forming position, and a thermal head 50 located onto the image forming position heats in accordance with image signals. With this energy, ink dispersion-retained in holes of the ink retaining body 30 is hear-dissolved so as to be solubly transferred to recording medium such as paper, thereby forming images in accordance with image signals on the recording medium 40.

Filed: 1984-02-17
Abstract: PURPOSE:To realize easily the shape of a scanning spot which is required for executing good light sanning by constituting the titled system so that a direction orthogonal to a joint surface of a semiconductor laser in a light scanning optical system corresponds in parallel to a main scanning direction. CONSTITUTION:Laser light L' from a semiconductor laser 10 is converted to a parallel luminous flux by a collimator lens 11, and its luminous flux section becomes an elliptical shape L2 having a long axis in the Y direction. Subsequently, the luminous flux transmits through a 1/2 wavelength plate 12, and the electric field vibrating direction rotates from the X direction to the Y direction, in a state that the luminous flux section shape remains held. Next, said luminous flux transmits through a cylindrical lens 4', is made incident on a hologram lattice disk 1, and executes main scanning to a surface to be scanned 9. In this way, when the Y direction orthogonal to a joint surface of the semiconductor laser is made to correspond in advance in parallel to the main scanning direction, a power of the first cylindrical lens itself used for the incident side to the disk 1 is reduced, and also a desired elliptical luminous flux section is obtained on the disk 1.

Abstract: PURPOSE:To prevent damage of a head body due to collision of a clamp by forming a protrusion protruding toward a platen drum from a heat generator outside an end face of the drum at a support member. CONSTITUTION:A clamp 8 is pulled back by a spring 12, and an end 2a is interposed to be held between the clamp 8 and an outer periphery 5a of a platen drum 5. When an end 2a of a color heat-sensitive recording material 2 is mounted on the drum 5, a stepping motor 7 is driven to rotate the drum 5. The drum 5 is rotated to move the end 2a held by the clamp 8 to a position opposed to a heat generator 13b of a head body 13a while winding the material 2 on an outer periphery 5a. Since a roller 26 is introduced into a cutout 30 of a head cam 28, a thermal head 13 is held at a retracted position and not brought into contact with the clamp 8.

CONSTITUTION:Unit inspection devices 13, 14, 15 and 16 in which an optical system group is formed integrally are provided, and by a driving source such as a motor, a rotary disk 12 is driven to rotate at a roughly constant speed. The inspecting devices 13-16 are placed at roughly equal intervals on the same periphery against the center of the rotary disk 12, and by attending with the rotation of the disk 12, a beam spot scans successively a printed board 10. Accordingly, when the board 10 is moved in the (y) direction, the whole of the substrate 10 can be scanned by the beam spot. At the time of the scan, the scan is executed like a locus 17, but immediately before that, the scan is executed like a locus 18, and when the scan is completed, the board 10 moves by a prescribed quantity in the (y) direction, and the movement is completed before the scan of the next inspection device 13 is started. In such a manner, there is no waste of time and the inspection can be ended in the minimum time.

Abstract: PURPOSE:To improve the recognition rate by coding a character pattern based on a so-called peripheral feature so as to recognize the pattern thereby precluding the possibility of the effect of the recognition by the fluctuation of an input pattern and applying the method for a rough classification in the recognition through the division of plural layers. CONSTITUTION:The code based on the peripheral feature is formed as to all characters of recognition object and the dictionary classified by the codes is provided. On the other hand, a document read by, e.g., an image reader is segmented one by one character by inter-line and intercharacter detection and the peripheral feature is detected as to the segmented character to form a code. Then the code from the segmented character is compared with a code provided to a dictionary and a character whose code is coincident is recognized. Thus, the recognition of rough classification is executed and the medium and small classifications are progressed, and the recognition is executed while the character pattern is coded, then the recognition is not affected by the fluctuation of input pattern and the recognition rate is improved remarkably.

Title: Product sum arithmetic circuit
Inventor: HARASAKI HIDENOBU
IPC: G06F17/10
Filed: 1987-02-09
Abstract: PURPOSE:To eliminate an overflow phenomenon by providing the number of arithmetic bits to an accumulator at the higher-order side than the output bit number of a multiplier and using the output of the accumulator as an input to perform a right shift by an optional bit number via a barrel shifter. CONSTITUTION:It is supposed that an input sample and a coefficient to be supplied to a multiplier 3 are set at a value between -1 and 1 and therefore the output of the multiplier 3 is also set at the value between -1 and 1. Thus N pieces of outputs of the multiplier 3 are totalized and therefore a dynamic range of totalization is increased up to N from -N. In this respect, plural bits are provided at the higher-order side than the MSB of the output of the multiplier 3 so that an overflow phenomenon is avoided. As a result, no scaling is needed for a coefficient and a product sum arithmetic operation is attained with high accuracy. In this case, a barrel shifter 5 having a right shift is used for right shift arithmetic so that the product sum arithmetic output is set at the value between -1 and 1. Thus a division is substantially carried out with a total number N.
