Abstract: PURPOSE:To provide the light beam scanning optical device of a much simpler constitution. CONSTITUTION:A laser beam L1 emitted by a specific light source 2 is separated by a spectral means 3, the intensity of the laser beam is detected from a branched beam L3 of the obtained laser beam, and the rest laser beam other than the branched beam are transmitted through the spectral means 3 to give astigmatism to the laser beam. Consequently, while the laser intensity of the laser beam is detected, the refractive index of the spectral means, the arrangement angle to the laser beam, etc., are adjusted to form a beam spot in a specific shape on a surface 7 irradiated with the laser beam and also correct the astigmatism of the laser beam itself. Thus, the light beam scanning optical device of a much simpler constitution can be obtained.

Abstract: PURPOSE:To optionally set the distance between image formation points of respective light beams, emitted by a light source, on an image formation surface by using cylindrical lenses which are arranged in front of and behind a scanning optical system so as to correct the surface tilts of the light beams by satisfying specific conditions for the focal lengths of 1st and 2nd cylindrical lenses. CONSTITUTION:The light beams emitted by the multi-beam light source 2 pass through a collimator lens 4, a 1st cylindrical lens 5, the scanning optical system, a 2nd cylindrical lens 7, and an ftheta lens 8 to irradiate the specific light receiving surface, which is scanned with image formation point width corresponding to the array direction of the light beams. Then, the equation is made to be satisfied with the focal lengths of the 1st and 2nd cylindrical lenses 5 and 6. Here, beta denotes the total magnifications of the multi-beam scanning optical device, f1 and f2 the focal lengths of the 1st and 2nd cylindrical lenses 5 and 6, F1 the focal length of the collimator lens 4, and F2 the focal length of the ftheta lens 8.

Abstract: PURPOSE:To control image-forming magnification on a photosenstive material so as to be within a prescribed change rate for a main scanning direction, to accelerate printing speed, and to perform imageforming on the photosensitive material without generating distortion by driving an image-forming lens group so as to interlock with a deflecting mirror for the main scanning direction by the deflecting mirror. CONSTITUTION:Distance between a leftmost terminal position DL or rightmost terminal position DR and a deflecting point P, and distance between a center position DC and the deflecting point P can be conformed to each other by correcting only by difference (e) by moving a movable lens 4 linearly by the minimum quantity synchronizing with the rotation of the deflecting mirror 2. Thereby, it is possible to uniformalize the distance until a multibeam LA arrives at an image-forming point on the photosensitive material 1, and as a result, the multibeam with almost uniform image-forming rate can be image- formed on the photosensitive material 1. Therefore, the image-forming rate can be set equally even when the image-forming is performed at any position on the photosensitive material 1.

Abstract: PURPOSE:To make the density of an image unified by providing pulse amplitude switching means for switching a voltage pulse amplitude to be supplied to a predetermined control electrode so as to make the quantity of electric charge for forming an electrostatic latent image to be formed on recording parts at every stylus electrode to be the same value. CONSTITUTION:For example, at time points t11-t12, an electrostatic latent image due to a positive voltage pulse P1A and a negative high voltage pulse P1CH is recorded at a recording part 4A1L on an electrostatic record medium 4, and an electrostatic latent image due to the voltage pulse P1A and a negative low voltage pulse P2CL is recorded at a recording part 4A1R. Here, when a switch 18CP is operated in accordance with a voltage switching signal from a CPU 20, an electrostatic latent image due to a positive voltage pulse P1B and a negative high voltage pulse P2CH is recorded at a recording part 4B1L at time points t12-t13, and an electrostatic latent image due to the positive voltage pulse P1B and a negative low voltage pulse P3CL is recorded at a recording part 4B1R. When a recording is to be done on the recording part 4B1, a re-recording function due to a remaining element voltage Vf and a crosstalk noise element voltage Vc is actuated, so that a quantity of electric charge to be accumulated in the recording part 4A1L becomes the same value as that of the recording part 4A1R.

Abstract: PURPOSE:To simplify the input in the case of drawing the same manuscript data by storing the image data from a manuscript data input means and/or a blackboard sheet data input means in an image memory means if necessary and selectively applying the same to at least one of a recording paper drawing means, a blackboard sheet drawing means and a transfer means. CONSTITUTION:The manuscript data from an image scanner 2 inputting manuscript data and/or the image data from a CCD line sensor 24 inputting the drawing data of a blackboard sheet 1 are stored in the desired frame memory of a memory 43 if necessary by operating the operation key of an operation panel 7. Further, the desired memory among the manuscript data from the image scanner 2, the drawing data of the blackboard sheet 1 from the CCD line sensor 25 and the drawing data stored in the memory 43 is selectively applied to a printer 3 and/or a recording head 25 and a transfer means 39 can be selectively operated. By this method, the drawing input in a case displaying the same drawing data on the blackboard sheet or in a case applying hard copy to recording paper can be simplified.

Abstract: PURPOSE:To obtain an electronic blackboard equipped with a display function capable of inputting the manuscript or book manuscript incapable of moving to the electronic blackboard by making a manuscript data input means freely detachable. CONSTITUTION:A receiving tray 6 for placing a felt pen 5 or an eraser 3 and an operation panel 7 for operating an electronic blackboard are arranged to an upper surface. A recessed part 4 is formed to the upper surface of a forward extension part and an image scanner 8 for inputting manuscript data is mounted to the recessed part 4 in a freely detachable manner. The image scanner 8 is positioned within the arm's length of the person using the electronic blackboard. Since the receiving tray 6 or the operation panel 7 are arranged to the part where the image scanner 8 is mounted, the operation inputting a paper manuscript to the image scanner 8 can be simply performed. When the image scanner 8 is separated, the manuscript 16 on a disk 16 present at a position separated from the main body of the electronic blackboard can be inputted and a book manuscript 17 can be inputted.

Abstract: PURPOSE:To almost completely fix a toner image by permitting a power source switching circuit to switch and flash fixing flash lamps disposed on a black board display material side and transfer device side. CONSTITUTION:The changeover switch 34 of a trigger power source 33 is so constituted to be operated by a signal switching the display action of an electrostatic recording medium 1 and the transfer action of a transfer mechanism 21. The fixing flash lamps 16 and 25 on the side of the electrostatic recording medium 1 and the side of the transfer mechanism 21 are switched to flash in response to the switching of the display and transfer actions of trigger electrodes 16c and 25c, with respect to the trigger power source 33, and therefore a display toner image on the side of the electrostatically recording medium 1 and a transfer toner image on a recording paper P on the side of the transfer mechanism 21 are surely adhered in a heat-molten condition, and they are not peeled off even if a user touches them carelessly. Consequently, the toner image is clearly displayed on the electrostatically recording medium 1, and clearly transferred onto the recording paper P. Thus, a toner image is stably adhered, thereby achieving sharp display and transfer.

Abstract: PURPOSE:To attain reception even if the carrier frequency differs for each broadcast station by mixing a 1st local oscillation signal of (f1+f2)/2 with a received broadcast signal to obtain an output signal of (f2-f1)/2, mixing a 2nd local oscillation signal of (f2-f1)/2+ or -fi with the output signal so as to obtain an signal of the intermediate frequency fi. CONSTITUTION:When a signal of the 1st local oscillation circuit 4 of (f1+f2)/2 and broadcast signal f1, f2 are mixed by a 1st mixing circuit 3 to obtain an output signal of (f2-f1)/2. The output signal and the signal of the 2nd local oscillation circuit 10 of (f2-f1)/2+ or -fi are mixed by a 2nd mixing circuit 9 to obtain an intermediate frequency signal fi even with the frequency of the 2nd local oscillation signal selected as (f2-f1)/2+fi (upper side heterodyne system) and even with the frequency of (f2-f1)/2-fi (lower side heterodyne system), and the intermediate frequency fi is always constant even when the carrier frequency is changed variously. Thus, the broadcast signal of the same content is received simultaneously even with different carrier frequencies f1, f2 for each broadcast station.
