Abstract: PURPOSE:To achieve the maniaturization and power conservation of a printer by fixing image receiving paper by a mechanical chucking mechanism consisting of an elastic member and a fixing member. CONSTITUTION:An arm or a cam is released and a pushed-up start end hook 34 is returned to its original position by the force of a spring 38. At this time, image receiving paper 4 is held by the start end hook 34 and fixed by the contraction force of the spring 38. Next, a rotary drum 32 is rotated and the image receiving paper 4 is wound around the rotary drum 32 along the almost entire surface thereof. Thereafter, the pin 41 of a movable block 36 and the fixing pin 42 of a rotary drum main body 32A forming a pair along with the pin 41 are clamped by a clamper. At this time, force is applied to a terminal hook 35 and the movable block 36 in the direction resisting against the force of a spring 43 and the terminal hook 35 is moved to the terminal position of the image receiving paper 4. At this position, the terminal hook 35 preliminarily drawn up by the arm or cam is released and the terminal of the image receiving paper 4 is fixed by the terminal hook 35.

Abstract: PURPOSE:To form a longitudinally long spot suitable for gradational expression without changing an optical system and sacrificing the resolution by assigning plural laser elements as a light source, and composing the longitudinally long laser spot of laser lights obtained by driving the laser elements at the same time. CONSTITUTION:As a hexagonal mirror 8 rotates, the spot position shifts from a point A to a point B on a photosensitive drum 1, and consequently, one scanning line is drawn. Then, the photosensitive drum 11 is rotated in a specific direction to draw lines in order, thereby forming one image called an electrostatic latent image on the photosensitive drum 11. Here, a multi-beam laser element is utilized as a laser unit 4 to form the longitudinally long spot. Namely, the laser elements are assigned as the light source which emits the laser lights for scanning the photosensitive body 11, and the laser lights obtained by driving the laser elements at the same time are put together to form the longitudinally long spot.

Abstract: PURPOSE:To prevent ghost phenomenon from occurring so as to improve, the quality of image by arranging stylus electrode groups facing each other at nearly among the centers of adjoining-control electrodes and high resistance parts constituting an electrostatic record medium in between adjoining control electrodes and facing about the center of the stylus electrode groups. CONSTITUTION:For example, when a recording is to be carried out on an electrostatic record medium 4 by a stylus electrode group A2 and control electrodes C3, C4, a stylus electrode A2R-1 to be arranged in between high resistance parts 4a2 and 4a3 among a stylus electrode A2R constituting the stylus electrode group A2 discharges together with a stylus electrode A2L and the control electrode C3. On the other hand, a stylus electrode 2AR' at a part where the stylus electrode A2R-1 is excepted from the stylus electrode A2R and a control electrode C4 discharge. Accordingly, when each high resistance parts 4ai is in between adjoining end parts (between interval D) of the adjoining control electrodes C3, C4, an area of the stylus electrode A2R' and the control electrode C4 for charging becomes the same as an area of a stylus electrode A2L' and the control electrode C3 for discharging. As a result, a quantity of electric charge to be accumulated in recording parts facing the electrodes A2R' and A2L' will not change.

CONSTITUTION:An electrostatic recording medium 1 as the blackboard display member is disposed so as to be transmitted endlessly through a feeding mortor 2 and a driving roller 3. An electrostatic recording head 6, a cleaning member 8 and a developing device 12 are provided while facing to the electrostatic recording medium 1. The blackboard display member 1 is provided with the mechanism which switches and displays the electing image and the mirror image on the blackboard display member 1 and the mechanism which transfers the image at the time the mirror image is displayed. Thus, an original information is displayed on the blackboard display member as the electing image as the original blackboard display and the electing image can be switched to the mirror image to be displayed. And at the time the mirror image is displayed, the image is transferred on the plain paper by corotron, etc., to be used as an enlarged copy.

These organotitanate, films 4, 5 enhance the adhesiveness of the base 1, the vibration plate 3 and the dry resist film 3. Therefore, the peeling of the base 1, the vibration plate 3 and the intermediate layers is prevented and durability can be improved and an emitting liquid can be normally emitted to enhance reliability.
