摘要： PURPOSE:To discriminate accurately the history of the use of a latent image carrier by inclining a part, which should be brought into contact with a reset member of a discriminating piece, to the direction perpendicular to the operating direction of the reset member. CONSTITUTION:A discriminating piece 52 is pressed by a reset member 51 of a counter 50 while setting a carrier unit 5 having no history of the use to an image forming device body. The part which should be brought into contact with the reset member 51 of the discriminating piece 52 before pressing is inclined to the direction perpendicular to the operating direction of the reset member 51 so that said part is approximately perpendicular to the operating direction of the reset member 51 when the discriminating piece 52 is bent.

摘要： PURPOSE: To form a vivid picture by reducing the load of a step motor and its variance and enhancing the precision of paper feeding in a latent image forming part by carrying a recording paper by the step motor up to the latent image forming part to store the recording paper in the position after this part.
CONSTITUTION: A step motor 2 is turned by a pulse signal for carrying a recording paper, and a recording paper 1 is taken out by a paper feeding roller 3 by driving of the motor 2 and is fed out toward a recording head 4 intermittently. A latent image is formed on the surface by this head 4, and the recording paper is fed to a feeding roller 12 through a cutter unit 5. At this time, the output of a photosensor 6b of a loop quantity detector 6 is set to L, and the roller 12 drive by a one-turn clutch 9 is stopped to store the recording paper 1 in a loop between the roller 12 and the unit 5. When the loop reaches a constant size, the light path of a light emitting diode 6a is broken, and the output of the sensor 6b is set to H, and the clutch 9 is released by a clutch solenoid 10, thus feeding the recording paper to developing and fixing parts in a constant speed.

摘要： PURPOSE:To miniaturize and stabilize an endless belt controller by using a system in which a skew-advancement detection signal level is divided into three levels, the intermediate level is made into an insensitive zone, and a solenoid for vertically moving rollers is operated at upper and lower levels. CONSTITUTION:In a belt skew-advancement detector 24, the contact condition betwen a lever 26 and a belt 11 is changed according to the skew-advancement condition of the belt 11, the lever 26 turns around a support shaft 28, a light detector 27 moves between an opaque portion 25a, a semi-transparent portion 25b, and a transparent portion 25c, and detection signal are sent out according to each condition. Of these signals, signal for the semitransparent portion 25b is regarded as an insensitive zone by a control circuit and the control circuit does not operate, but signals positioned in the opaque portion 25a and the transparent portion 25c are judged as a skew-advancement condition. The solenoid for vertically moving conveyer rollers (not illustrate) is put into on-off action, and the roller positions are corrected. Only one skew-advancement detector is thus sufficient, and the miniaturization and stabilization of the belt position controller can be attained.

摘要： PURPOSE:To set and reset and convert the pressure of a pressure roll easily in safety by providing a fixation device which consists of a heat roll and a heating roll with the pressure lever and an auxiliary lever which share one supporting shaft, and energizing the pressure roll against the heat roll, and releasing the pressure roll from being energized. CONSTITUTION:The pressure lever 4 and the auxiliary lever 5 share a fulcrum 6 and when the auxiliary lever 5 rotates clockwise around the fulcrum, its side edge abuts on a stopper 8 on the pressure lever 4 to eliminate relative movement between both levers. A pressure spring 7 is extended between both levers 4 and 5. When the auxiliary lever 5 is rotated counterclockwise, the pressure lever 4 rotates following after the auxiliary lever 5 as if they are incorporated in one body, but it abuts on the outer circumference of the bearing 29 of the pressure roll 3 soon. When the auxiliary lever 5 is further rotated, the tensile force of the pressure spring 7 is exerted on a bearng 29 through the lever 8. At this time, a clamp lever 9 is operated to hold a clamping state stably because the auxiliary lever 5 is set.
