Title: Printing hammer drive circuit
Inventor: OOTA TAKASHI
IPC: B41J2/295
Filed: 1986-01-31
Abstract: PURPOSE:To obtain a printing hammer drive circuit capable of accelerating printing operation by providing a plurality of piezoelectric elements which generates an expansion force through a drive voltage to drive a flight hammer, discharges an electric charge accumulated by a discharging circuit to cause a contraction action and reduces an impact force when the flight hammer is returned to an original position. CONSTITUTION:A drive voltage is increased, a piezoelectric element 3 is increasingly expanded, the tip of the piezoelectric element 3 and a flight hammer 4 are accelerated and the flight hammer 4 is separated from the piezoelectric element 3 flying. A printing wire 41 runs into a platen 7, printing dots. After the elapse of a certain time from the starting of a printing gate signal, a discharge gate signal is output to turn ON a transistor Q2 of a switching element, and thereby an electric charge accumulated in the piezoelectric element 3 is discharged through a resistor R2. The piezoelectric element 3 contracts and the flight hammer 4 hits while the tip of the piezoelectric element is undergoing a reduction in displacement. Since it is possible to reduce the relative speed of the piezoelectric element 3 and the flight hammer 4, the recoiling of the flight hammer 4 is lessened and is quickly restored to a standstill. As a result, a time required until a next printing action is commenced can be shortened and printing be accelerated.

Title: Image forming method by electrophotographic method
Inventor: KOMIZO SHIGEO
IPC: G03G21/00
Filed: 1978-02-24
Abstract: PURPOSE:To achieve the improvement of the tone reproducibility of copied images by providing a light radiating process before tempering to a photoreceptor and changing original-image density characteristics. CONSTITUTION:When light is radiated from a light source 2 to the original 1, the reflected light of the intensity proportional to the original density images on the exposure plane 4 through optical system 3. On the other hand, a photoreceptor 6 is evenly charged by a charger 7. When the original images are radiated in the exposure part 4, the surface potentials of respective parts lower according to the quantity of exposure light owing to the light attenuating characteristics of the photoreceptor 6, thereby forming the electrostatic latent images. These are then developed in a developing part 8 and are fixed to sensible images in a fixing part 9. The light attenuating characteristics of the photoreceptor which has been radiated beforehand with light of high intensity before entering such copying process result in decreased charge saturation surface potentials, thereby decreasing the rate of light attenuation. Hence, arrangement is so made that prior radiation of light is applied to the copying photoreceptor 6 by a sub light source 10 before the copying process is started. Thereby, the tone reproducibility of the copied images may be improved.
