摘要： PURPOSE:To obtain an image having no ghost, and also, having a good color purity by constituting the titled device so that only a light beam of P wave polarization is made incident on a dichroic mirror, in case of synthesizing a light beam which has transmitted through plural TN type liquid crystal panels, by the dichroic mirror. CONSTITUTION:A light beam from a light source 1 is made incident on condenser lenses 3,3 directly, or by being reflected by cold mirrors 2, 2, and generated as parallel rays. This parallel rays are reflected by reflecting mirrors 5, 5 through heat insulating filters 4, 4 and supplied to liquid crystal panels 6, 7. A light beam which has transmitted through a polarizing plate, a liquid crystal panel 7, and a polarizing plate 9, and a light beam which has transmitted through the polarizing plate 8, the liquid crystal panel 6, and the polarizing plate 9 become light beams of P wave polarization, and this light beam is converged by theta by convex lenses 11, 11 and supplied to a dichroic mirror 10. Therefore, a light beam of G which has transmitted through the liquid crystal panel 7 is reflected, and a light beam of R and B, which has transmitted through the liquid crystal panel 6 transmits through and synthesized, and projected by a projection lens system 12. In this way, a ghost on the screen is eliminated, and an image having a good color purity is obtained.

摘要： PURPOSE: To provide the picture recorder which copes with even recording of moving pictures with a simple constitution and can record pictures of high quality by displaying only the picture signal equivalent to one picture on a CRT and recording this display picture. CONSTITUTION: When a print switch 5 is depressed, a shutter of 'a shutter unit 11 starts opening, and flip flops 42 and 43 of a timing circuit 4 are triggered by the first inputted vertical synchronizing signal, and a gate circuit 44 is opened by the inverted output of the flip flop 43. Q output '1' of the flip flop 42 passes the gate circuit 44 and is inputted to a switching circuit 3 as the switching signal, and the output is switched from a black signal to a picture signal, and the picture signal of one picture is outputted and is recorded on a photosensitive body 8. When the vertical synchronizing signal is generated after the end of this output, the switching signal goes to '0', and the black signal is outputted again and the shutter is closed.

摘要： PURPOSE:To provide an image recorder which executes high-quality recording by controlling recording timing and which uses a liquid crystal panel. CONSTITUTION:When a vertical synchronizing signal is inputted by depressing a printing switch 13, light is projected from a light source 2 through a red filter 6 in a state where the display of one picture corresponding to red is finished. After this light emission is finished, a green filter 7 is arranged in the optical path and the picture corresponding to green is displayed. When the display of one picture is finished, the light is projected from the light source 2 and a green video is superposed on the red picture on a photoreceptor 4. Next, a blue filter 8 is arranged in the optical path and the picture corresponding to blue is displayed. When the display of one picture is finished, the light is projected from the light source 2 and a blue video is superposed on the recording in which green and red are superposed. A color recording is thus obtained.

摘要： PURPOSE:To obtain a bright color recording image within a short period of recording time and with a simple constitution by exposing the emitted light colors of at least two adjacent pixels overlappingly on a photosensitive body. CONSTITUTION:When a light is emitted from a backlight light source 2, the display screen of a color liquid crystal display panel 1 is projected toward a photosensitive body 5 and reach a light diffusing plate 6. The pixel parts of the three original colors of this emitted light is diffused and projected on the photosensitive body 5 by the light diffusing plate 6. That is, emitted lights of adjacent pixels are exposed overlappingly on the photosensitive body 5. Thus, an image exposed on the photosensitive body 5 is made bright by overlapping of the three original colors of a light at a specified rate.

摘要： PURPOSE:To remove the complication of operation by performing copying action continuously without pressing a switch again in the case that power source voltage is equal to or above specified voltage. CONSTITUTION:When a lock switch LKsw is turned on, the signal P1 of output H is supplied from a control means 41 to a voltage stabilization circuit 42, which is allowed to act. Then, power is supplied to a motor 23 and an illumination means 24 through a motor driving circuit 43 and an illumination driving circuit 44, thereby executing copying. When a start switch Ssw is turned on, the motor 23 is driven and an optical means executes copying. The control means 41 detects the power source voltage by the use of a voltage detection means 45 before the copying action based on the on-action of the Ssw. When both the LKsw and the Ssw are turned on, the copying action is performed continuously in the case of detecting the voltage equal to or above the specified voltage, and when the LKsw is turned off and the Ssw is turned on, only the detection of the power source voltage is performed. In the case that the power source voltage is low, the signal P5 of the output H is supplied from the voltage detection means 45 to the control means 41 so as to control the copying to be impossible.

摘要： PURPOSE:To execute correct, battery check by applying a current nearly the same as a load current at the time of acting and to prevent film from being exposed. CONSTITUTION:When a lock switch LKsw is turned on, the signal P1 of output H is supplied from a control means 41 to a voltage stabilization circuit 42, which is allowed to act. Then, power is supplied to a motor 23 and an illumination means 24 through a motor driving circuit 43 and an illumination driving circuit 44, thereby executing copying. When a start switch Ssw is turned on, the motor 23 is driven and an optical means passes a light shielding position and arrives at an exposing position, thereby executing copying. The control means 41 starts the motor 23 before the copying action to move the optical means within the range of the light shielding position, and controls so that the power source voltage is detected by a voltage detection means 45 while the optical means is moved. In the case that the power source voltage is low, the signal P5 of the output H is supplied from the voltage detection means 45 to the control means 41 so as to control the copying to be impossible. It is also allowed to detect the power source voltage in both go-and-return directions that the optical means goes and returns within the range of the light shielding position.

摘要： PURPOSE:To attain the entry while visually observing coordinates of a reference point on a tablet panel and to detect the relation of position between a line sensor and a pickup element by providing at least one pickup element at the position visually recognized. CONSTITUTION:A paper sheet is set on a tablet panel 1 and a reference point CP is marked at an optional position. The mode to read a coordinate of a pickup element 3a on the panel 1 is set by the switch operation and a mode changeover circuit 4 outputs only an output signal of the element 3a. The center point of the element 3a is matched with the point CP by visual observation and x/y scanning circuits 6a,6b scan the panel 1 to read the coordinate of the point CP. The mode is switched into the picture input mode by the switch operation and the circuit 4 outputs a signal of pickup elements 3a,3b. A line sensor 2 is scanned to allow an image pickup element Pa to pick up the point CP and to detect coordinates of points La, Ra at the center position of the elements 3a,3b and the result is stored in a storage circuit 8. A control circuit 7 detects a relative relation of positions among the elements 3a,3b,Pa based on the points CP,La and Ra.
