Abstract: PURPOSE:To reduce the load of a microcomputer and also to simplify the constitution of the output control software, by forming the memory parts and input/ output ports on the same chip and delivering the selected data within memory parts directly to the input/output ports. CONSTITUTION:Input/output ports PA0-PC0 and PA1-PC1 and memory parts RAM0-n-RAM7-n are formed on the same semiconductor chip. Command registers Cont0 and Cont1 define the inputs and outputs of said input/output ports. The parts RAM0-n-RAM7-n store data and also transfer data selectively to the ports PA0-PC0 and PA1-PC1 by the commands supplied to registers Cont0 and Cont1.

Abstract: PURPOSE:To increase number of time division without decreasing an image forming speed by disposing microshutter group which sandwiches a liquid crystal between a substrate provided with plural segment electrodes and a substrate provided with a common electrode into the optical path for exposure. CONSTITUTION:An FET formed on the substrate 301 is provided with a gate electrode 302 connected to a gate line, a source electrode 303 connected to a data line and a drain electrode 304 for taking out a data signal. The electrode 304 is connected to the segment electrodes 307 forming a shutter part. The resistance of an a-Si film 305 decreases and the electrodes 303 and 304 are made conducting when a scanning signal is impressed to the electrode 302. The liquid crystal element is formed by sandwiching the N-P type liquid crystal between the substrate 301 and the counter substrate 311 in the orientation state and a transparent common electrode 312, a light shielding film 314 and an orientation control film 315 are provided on the substrate 311. The liquid crystal shutter array consisting of such element is disposed in the optical path for exposure via orthogonal polarizing plates 319, 320, by which the number of time division is increased without decreasing the image forming speed.

Abstract: PURPOSE:To enable to print multiple gradations at high speed by a matrix driving system by providing an LED array driving circuit comprising a means for repeating similar n-time-division driving at least two times for the same row when producing picture elements for one row. CONSTITUTION:A data (image) signal D, in which gradation data expressing the density of each picture element by 2 bits are provided in parallel, is fed in syncronism with a clock signal Clk while a data enable signal EN is ''1''. When performing n-time-division m-picture-element simultaneous production in accordance with a one-row amount of the image signal, m-picture elements are simultaneously produced in a period of time which is not equal to 1/n of the period of time required for producing one row of picture elements but equal to 1/(jXn) of said period, wherein (j) is an integer of 2 or more, and the one row of the picture elements are produced by repeating (j) times the n-time-division m- picture-element simultaneous production. In addition, the turning-ON and turning- OFF of LEDs are controlled at each time of the n-time-division m-picture-element simultaneous production in accordance with the gradation data indicating the density of each picture element.

Abstract: PURPOSE:To execute high speed printing by employing a matrix driving system by proving an LED array driving circuit having a device to repeat similar (n) time-division driving to the same row at least two times to form picture elements for a row's share. CONSTITUTION:When picture elements for a row are formed by simultaneous forming of 4 times of n time division (m) picture elements, data signal D of data for a row's share is sent to a section in which data enable signal EN is ''1'' synchronizing to a clock signal C1k continuously in a time at least less than 1/4 of data signal transmission period for a row. When the data enable signal rises, a timing generator 901 clears the address of controlling signal to a memory 902 to ''0'' by a writing mode, and sets a controlling signal 905 to switch a selector 904 to data signal D side. Thus, by storing picture data for a row's share in the memory 902, and reading repeatedly picture data for a row's share, picture elements for a row's share are formed by plural times of n time division m picture element simultaneous forming.

Abstract: PURPOSE:To improve the operability by starting an image formation preparing process by a signal of a data input means, and starting an image forming process by a signal from a displacement detecting means. CONSTITUTION:When a data is inputted to a data inputting means 3 by operating a keyboard 31, an information signal is outputted to a display means 2 through a signal line 4a in accordance with a program stored in a memory 38. On the other hand, this information signal is outputted simultaneously through a signal line 4a to a control sytem 8 of a copying machine 1, too, becomes a copy preparing command, and a copy preparing process is started. Accordingly, when it is desired to convert a picture displayed on the display means 2 to a hard copy, a detecting switch 1d becomes on if only the display means 2 is laid down onto an original placing plate glass, its signal becomes a copy start command to the control system 8, and a copy process can be executed immediately.

Abstract: PURPOSE:To speed up picture formation by forming respective read-out picture element data as the picture data of one row through plural storage means and driving means. CONSTITUTION:The anodes of respective LEDs 30 arranged on one row are connected to respective outputs of N drivers 31-1-31-n. If one row is to be expressed by M picture elements, M LEDs are used and M/N-bit shift registers are used as respective shift registers 33-1-33-n. Consequently, the data of one row are set up in the shift registers 33-1-33-n by applying the data of M/N pulses to data lines Data 1-Data N synchronously with a clock signal on a clock line OCK. At the timing, a pulse is applied to a strobing line OLG and the data of one row are latched to turn on/off respective LEDs 30.
