Title: Image forming device
Inventor: AKANUMA HIROYUKI
IPC: G03G21/14
Filed: 1994-09-14
Abstract: PURPOSE: To form an image having no defects such as fogging by preventing the unevenness of potential in an image carrier by electrification which occurs when a contact electrifying member is used as an electrifying means for the image carrier, in an electrophotographic image forming device. CONSTITUTION: The DC voltage component of an AC-superimposed DC voltage applied to the contact electrifying member 2 arranged in contact with the image carrier 1 is controlled by a controller 9, based on the timing of the operation of an image writing device 4 or a transfer device 6.

Title: Active range finder
Inventor: SUZUKI RYOICHI
IPC: G03B13/36
Filed: 1994-09-14
Abstract: PURPOSE: To improve the accuracy of an active range finder by positioning a second light receiving optical system for correcting contrast incorporating a second light receiving element and second light receiving lens near a light emitting optical system perpendicular to the length direction of a base line in addition to a light receiving optical system for measuring distance incorporating a first light receiving element and first light receiving lens. CONSTITUTION: Since an infrared-ray emitting diode(IRED) 16 and semiconductor position detecting element (PSD) 18 for measuring distance are separated from each other by the length of a base line, the image of the reflected spot of the IRED 16 on the PSD 18 moves in the length direction of the base line in corresponding to a subject distance. Since the distance between a PSD 2 for correcting contrast and the IRED 16 in the length direction of the base line is substantially zero, the image of the reflected spot of the IRED 16 does not move toward the base line in corresponding to the subject distance. Therefore, the length X2 of the PSD 20 becomes sufficiently long when the length X2 is equal to or longer than the maximum width of the image of the reflected spot.  In addition, since the distance between the PSD 18 and IRED 16 in the direction perpendicular to the length direction of the base line is substantially zero, the width Y1 of the PSD 18 becomes sufficiently wider when the width is equal to or wider than the maximum width of the image of the reflected spot.

Title: Developing method by electrophotographic method
Inventor: KATOU MAMORU
IPC: G03G15/09
Filed: 1983-12-28
Abstract: PURPOSE:To evade the rubbing of a brush of carriers against an image by mixing and charging electrostatically chargeble toner and magnetic carriers and movingd only the toner in the mixer on the surface of a developer supply roll to a toner developing roll. CONSTITUTION:The chargeble toner and magnetic carriers 5 are mixed and charged electrostatically by friction by a stirrer 7 and biased by a power source 15 between a developer supply roll 8 and the toner developing roll 9, and only the charged toner 4 is moved to the conductive surface 14 to form a toner layer 4a. The mixing of the toner 4 and carriers 5 charges the toner intensely and uniformly and the scooping to the roll 8 is facilitated by the magnetic attractive force of the carriers to form the magnetic brush excellently on the roll 8. Therefore, the toner layer 4a sticking uniformly on the surface of the roll 9 contacts a photosensitive layer 1 to form a sharp image without any brush mark while evading the rubbing of the magnetic carriers 5 against the image.
