Title: Controller for copying machine
Inventor: TAKASHINA SHINJI
IPC: G03B27/62
Filed: 1983-07-22
Abstract: PURPOSE:To prevent evil influence which may be exerted on a photosensitive body and the malfunction of a device by providing a means which inhibits the start of copying operation even when a platen cover is closed to a copying machine which starts copying operation when the platen cover is closed. CONSTITUTION:A contact 9a is made unless an inhibition key 9 is set. When the platen cover 4 is closed, a switch 6 is operated by an actuator 5 to make a contact 6a. Then, Vcc is applied to an inverter 11 through the contacts 6a and 9a, so a 0 signal commanding copying operation is inputted to a control part 10. The control part 10 operates a driving circuit 14 and a copy operation means 13 starts the copying operation. When the inhibition key 9 is set, on the other hand, the contact 9a is broken, so the 0 signal is not inputted to the control part 10 even when the platen cover 4 is closed, so the copying operation is not started. The cover 4 eliminates evil influence which may be exerted upon the photosensitive body and the malfunction is prevented with the inhibition key 9.

Abstract: PURPOSE:To maintain the filling ratio of two kinds of materials to be packaged at a specified value at all times by discharging a fixed amount of the materials according to a specified packaging ratio and feeding the materials into a space between films for packaging after the materials are mixed with each other by a mixer. CONSTITUTION:In supplying two kinds of liquids in a specified ratio, the respective liquids 11, 12 are pumped up in a fixed amount of each liquid at a time by pumps 13, 14. Both the liquids 11, 12 are allowed to flow into a motionless mixer, in which both the liquids 11, 12 are well mixed together irrespective of their differences in specific gravity. The mixed liquid of both the liquid 11, 12 is then fed into a space between films for packaging through a feeding nozzle 8. By this method, the two kinds of the liquids 11, 12 are thoroughly uniformly mixed with each other to be fed into the space between the films. Therefore, separation of the liquids from each other, which may be caused due to the difference in specific gravity, can be effectively prevented.

Title: Half tone controller for image forming device
Inventor: SASAHARA TATSUO
IPC: H04N1/23
Filed: 1988-05-31
Abstract: PURPOSE:To obtain half tone of a high resolution with a simple device constitution by controlling a laser wavelength control part according to the density of an image formed on a photosensitive body and changing the wavelength of a scanning beam. CONSTITUTION:By driving a laser turning-on/off circuit 1, the irradiation of a scanning beam from a laser device 3 is controlled to be turned on/off. When gradation data corresponding to image density is transmitted to a laser wavelength control circuit 2, it variably adjusts the wavelength of the scanning beam projected from the laser device 3. The scanning beam whose wavelength is changed by the circuit 2 according to the gradation is oscillated by a rotary polygon mirror 5 at a fixed frequency, and is focused by an image forming lens 6 on the surface of a photosensitive drum 7, thereby forming the amount of electric charges corresponding to the gradation of an image. Thus, an appropriate half tone is attainable with the simple device constitution without lowering resolution.

Filed: 1993-05-13
Abstract: PURPOSE:To carry muck of a shield device effectively by arranging an elastic tube in a support shape on a carriage, and performing squeezing-out operation on the tube by the movement of a sliding frame and pressing pistons. CONSTITUTION:Rollers 34 and 64 of the first and the second push-pressing pistons 30 and 60 on a sliding frame 27 move in the arrow G direction from a front end part 21A through a closed part of a muck carrying passage R1 of an elastic tube 21 while holding and pressing the left and right side surfaces 21c and 21d of the elastic tube 21 interposingly between them. The rollers 34 and 64 move on the left side surface 21c and the right side surface 21d in the arrow G direction while rotating in the arrow (eta1 and /eta2) directions with rotational center lines CT34 and CT64 as their centers. Friction between the pressing surfaces 34a and 64a and the left and right side surfaces 21c and 21d can be reduced. Muck 50 and small stones 50a in the muck carrying passage R1 are squeezed out toward a muck discharge port 21d by the movement of the rollers 34 and 64, that is, the movement of a closed part. Even the small stones 50 apt to stay in the bottom part of the inner peripheral surface 21e of the elastic tube 21 can be carried suitably due to heavy specific gravity.
