摘要： PURPOSE:To obtain an inexpensive recorder which requires no manual operation, can be corrected and adjusted readily and quickly and has excellent color reproducibility by providing a transmissive monochromic display, a controller, a photographing device, a transmitting light source, an optical sensor and a light control means. CONSTITUTION:The controller 2 transmit a picture signal to the transmissive monochromic liquid crystal display device 1, selects a color of the transmitting light source 4 and instructs the source 4 to generate light in synchronization with picture display. At this time, the quantity of generated light is detected and when the quantity reaches a prescribed value, light generation is interrupted. The photographing device 3 takes a picture on the device 1 illuminated with the generated light to record it. With respect to action timing, plural frames of the same figure, etc., are displayed at the timing of a signal R included in a signal 5. After the display is stabilized, the light source 4 is selectively caused to generate light by means of a signal (r) included in a light source control signal 61, and the light control means 8 controls the quantity of generated light with the aid of an output from the optical sensor 7, following which pictures displayed with signals (g) and (r), instead of the signal 5, are composed and recorded. Thus, the entire process can be automated by applying a general-purpose computer to the device 2, instead of a color CRT, and the device becomes more inexpensive. In addition, color reproducibility is improved.

摘要： PURPOSE:To utilize an analog gradation RGB picture signal as it is and to attain the recording reproducing an intermediate color with fidelity by displaying a picture on a transmission type monochromatic liquid crystal display device and picking up the displayed picture by a pickup device. CONSTITUTION:An A/D converter circuit 201 converts an analog gradation picture signal into a digital picture data. Then a bit location selection signal generating section 203 selects one bit from a digital picture data by using a signal from a bit location selection signal generating section 205 generating a signal to select a bit sequentially and a signal from a color selection signal generating section 206 to select a light source color of a transmission color light source 4 at a color light source control section 202 based on the result of comparison of a time control section 204 controlling a time to select a specific bit and a time lighting the transmission color light source 4 and the picture is displayed on the transmission type monochromatic liquid crystal display device 1 as a binary picture element data and the picture is picked up by the image pickup device 3. Thus, the color gradation picture suppressing the picture element density and the reduction of the chromaticity is recorded.

摘要： PURPOSE:To execute switching of a throttle operation and a light non- transmission state at a high speed, and also, to reduce the deterioration of a liquid crystal by using the liquid crystal whose dielectric anisotropy is reversed by a frequency, applying a high frequency voltage, and executing the throttle operation by a low frequency voltage. CONSTITUTION:A liquid crystal between the upper plate 2 and the lower plate of a cell 1 shows a positive dielectric anisotropy and goes to a light non- transmission state, when for instance, the voltage of a low frequency of =10kHz is applied. At the time of operation, power sources 14, 15 are grounded, and a power source 13 generates a low frequency voltage, and sets the cell to the light non- transmission state. Subsequently, when the power source 13 is set to a high frequency of about 10V-scores of V, and the power source 14 is set to above the voltage of the power source 13, and the power source 15 is set to below the voltage of the power source 13, a throttle operation is executed.

摘要： PURPOSE:To control light transmission in an intermediate stage stably at a high speed by arranging electrodes and wiring parts which form window parts to an upper and a lower plate between which specific liquid crystal is charged in a necessary way and driving them as specified. CONSTITUTION:A lower plate 3 where the liquid crystal which varies in dielectric anisotropy with frequency is provided with electrodes 10-a and 10-e and wiring parts 20-a-20-d, etc., which drive them, and a lower plate 2 is provided with wiring parts 21A and 21B for driving corresponding electrodes 9-A and 9-E and odd-numbered and even-numbered electrodes. One of a couple of opposite electrodes selected among those electrodes is applied with a high frequency signal and the other is applied with an in-phase high frequency signal with low wave height. In another way, one electrode is lowered in crest value as low frequency driving. Then, a voltage distribution varies from one end of a window part to the other end and liquid crystal orientation variation narrows down accordingly, so that even light transmission in the intermediate stage is controlled stably at a high speed. When one electrode is driven at high frequency and the other electrode is driven at low frequency, the window part enters a nontransmission state.

摘要： PURPOSE:To control stably the area of a transmission or reflection region and to express the density of an intermediate stage by providing two electrodes which are electrically connected to a main electrode and are separated from each other and impressing independently the voltage different from the voltage to be impressed to the remaining main electrode to the separated electrodes. CONSTITUTION:A basic cell 1 is constituted by adhering rightly an upper plate 2, a spacer 4 and a lower plate 3 to each other and packing a liquid crystal into the space between the upper plate 2 and the lower plate 3 generated by the spacer 4. The boundaries on the inside of the electrodes 6 and 5 on the lower plate 3 are designated respectively as A and B. A signal voltage is inputted to the electrode 6 and the electrode 5 and the electrode 7 of the upper plate 2 are grounded. The electrode 8, when provided, is grounded or kept afloat. The current flows toward the grounded electrode 5 and the transparent electrode acts as a resistor when the signal voltage is impressed to the electrode 5 and therefore the voltage distribution falling approximately linearly from the position A toward the position B is formed in the electrode 9. The voltage corresponding to the difference between the voltage formed on the transparent electrode 9 of the lower plate 3 and the grounded transparent electrode 10 of the upper plate 2 is impressed to the liquid crystal and the light trnsmittance is partly changed.

摘要： PURPOSE:To prevent the deterioration in resolution and to attain intermediate recording by impressing the voltage of a reversed or the same polarity as that used for forming an electrostatic image in the required timing on an external needle electrode so as to obtain the electrostatic image in the prescribed size. CONSTITUTION:A multi-needle electrode 1 is vibrated in the electrode array direction with the use of a vibrator 6, and simultaneously in the prescribed timing the voltage of the reversed polarity 1 or the same polarity 15 as that used for forming an electrostatic latent image is impressed on the multi-needle electrode 1 through a switch 13 to obtain the electrostatic image in the prescribed size. Since the multi-needle electrode 1 is always vibrated, a larger or smaller electrostatic image than the magnitude of each electrode can be obtained only by the polarity of the impressed voltage and the timing of impressing the voltage.
