Abstract: PURPOSE:To surely select picture elements comprising a partial picture that an operator specifies by permitting a position specification means to judge that said picture elements are specified ones when specified coordinates are judged to lie within a mouse area. CONSTITUTION:A picture comprising table is stored in a memory 202, and has lines e1-en. Each line stores identifiers corresponding to picture comprising elements and coordinate transformation constants. When the inputted coordinates are judged to lie within an area for the picture elements comprising the partial picture, relative coordinates corresponding to masking data about said picture elements are calculated. Then such judgement is made that the positions of the calculated relative coordinates lie in which positions in the masking data. If the results shows that the picture having been displayed lies in an area to be held, the inputted coordinates are not on the line e1, and the operation shifts to a next retrieval. When the relative coordinates lie in the area where the picture having been displayed of the masking data is masked, the picture elements on the line e1 are judged to ones that the operator specifies, and the operation ends.

Abstract: PURPOSE:To designate the ranges and positions of complied characters and compiled character strings by using the setting means for displacement information, character position designation mode, character string designation mode, etc., in addition to the input of character information. CONSTITUTION:In a compiling mode the characters can be compiled when a range designating key is turned on. While a single character compiling mode is set when said range designating key is turned off. Then the caret position compiling is possible when a position designating key is turned on. The value of a present position counter is replaced for each character in response to the input of replacement of a rotary disk 108 (303). These counter and flag information are stored in the RAM 305-2 of a memory 305 and then processed by a CPU 301 to be displayed on a liquid crystal display device 107. The device 107 displays the character strings within a range covering the displayed head counter value through + (m-1) and the display is changed in an out-of-display range. Then the character strings under selection are displayed with black-while inversion.

Abstract: PURPOSE:To increase the degree of freedom of the design by selecting positive or negative logic of the circuit so as to design, e.g., a program or a gate circuit without taking the state of a controlled circuit into account. CONSTITUTION:In constituting a positive/negative logic selecting means by an exclusive OR circuit 304, with a terminal 305 pulled up, ports 302-0-302-3 go all to a low level at the application of power and with the terminal 305 connected to ground, the ports 302-0-302-3 go all to a high level at the application of power. Thus, in case of the titled circuit used for output ports of a control circuit used frequently for a relay, a plunger or a clutch, the terminal 305 is pulled up by a resistor R401 so as to prevent a load such as a relay from being driven at the application of power.

Abstract: PURPOSE:To obtain a copied picture image in true focus even when the original is uneven by measuring the distance from the image forming reference plane of an original placed on an original setting table with the face to be copied facing upward to the face to be copied before exposing and keeping the length of light path from the face to be copied to a photosensitive body according to the measured value. CONSTITUTION:A book 1 is placed on a book cassette 2 mounted on an original setting table 5 with the face to be copied (f) facing upward. When a copy command switch is depressed, the original setting table 5 starts moving at a constant speed, and the distance between a distance measuring device 7 and the face to be copied (f) of the book 1 is measured, and the measured value is outputted to a controlling circuit 30. The rate of change of the distance from the image forming reference plane of the original to the face to be copied is calculated from positional information of output of the distance measuring means and exposure scanning direction of the distance measuring means. When an area in which the rate of change is large and does not require copying is calculated, feeding of transfer paper is delayed for the area.

Abstract: PURPOSE:To obtain a copied picture image in exact focusing even when an original is uneven by measuring the distance from the reference plane of image forming of an original placed on an original stand with its copied face facing upward and the copied face before exposure scanning and keeping the length of light path from the copied face to a photosensitive body constant according to the measured value. CONSTITUTION:When a measured value by a distance measuring device 7 is inputted to a controlling circuit 30 and the distance from the reference plane of image forming Yk to the copied face f of a book 1 is known as Yn, positional information in the direction of exposure scanning of the book 1 corresponding to the distance Yn is inputted to a memory 35. Supposing that the speed of an original stand 5 is v, the distance between the distance measuring device 7 and mirror reference position MS is Xs and the length of exposure from the reference plane of image forming Yk to a photosensitive drum 11 a time Xs/v is L, the length of light path L becomes shorter by Yn after further lapse of a fixed time from the point of time, and accordingly, the image on the photosensitive drum 11 becomes out of focus. In such a case, mirrors 91, 92 are driven by a mirror driving section 34 and shifted upward by a distance Yn/2 to maintain the length of light path constant.
