摘要： An original is moved by a feed motor so as to read the original by the combination of a light source and a CCD. The image information thus read is stored into the memory. The image information stored in the memory is sent out via a modem to the phone line. The amount of data stored in the memory is detected: if the amount of data exceeds the first predetermined amount, the speed of movement of the original is gradually reduced while if the amount of data becomes equal to or smaller than a second predetermined amount which is smaller than the first predetermined amount, the speed of movement of the original is gradually raised.

摘要： A thermal recording apparatus includes a thermal head. Printing for multi-tone density is performed by changing an energizing time of the thermal head. The apparatus has a controller for controlling the energizing time and an interrupting circuit. The controller controls the energizing time to match to a value corresponding to a tone density for printing. The interrupting circuit puts an interrupt period of energizing for the energizing time if the energizing time is equal to or more than a predetermined time. The thermal head is pre-heated when printing data is not zero so that linear relation between the energizing time and the printing density can be obtained even if the printing density is low.

摘要： An image reading apparatus comprising a lighting control means, an analog shift means, a transfer control means and a clock pulse control means. According to the controlling operation of a lighting control means for lighting the light source during a given time period, the output of the CCD sensor is prohibited from being fed to the analog shift means while the light source is turned on, with the output of the CCD sensor being adapted to be fed to the analog shift means and to shift to an output circuit while the light source is turned off, thus preventing the accumulation of light electric-charges, caused by light leakage within a light-source lighting period, and preventing mixed color reading through the remaining electric charges, with the result that the color resolution of the red, green, blue can be performed with accuracy.

摘要： A multi-pin-electrode electrostatic recording system includes a recording head having 2048 pin electrodes aligned in a line and 65 pairs of auxiliary electrodes positioned near the pin electrodes. A negative recording pulse is applied to a selected pin electrode when a positive recording pulse is applied to a corresponding pair of auxiliary electrodes to form an electrostatic latent image on a dielectric layer of a recording paper. A compensation negative voltage pulse is applied to the auxiliary electrodes, the compensation negative voltage pulse having a pulsewidth longer than the positive recording pulse and the positive recording pulse being superimposed on the compensation negative voltage pulse. By the compensation negative voltage pulse, the occurrence of the ghost image on the non-selected image point is eliminated.

摘要： It is an object of the invention to allow effective use of a memory provided for each function in a complex image processing apparatus including a facsimile apparatus, to increase the reception capacity of a memory reception function when the apparatus works as a facsimile apparatus and to enable sorting of received facsimile data. In the complex image processing apparatus, facsimile data received via a modem section is accumulated in a memory for facsimile. Under predetermined conditions, the facsimile data in the memory for facsimile are grouped, rearranged and transferred to a memory for copier and a memory for printer. Conditions for causing data rearrangement and transfer may be set such that they occur when a predetermined time passes after the beginning of the operation of the memory reception function or such that they occur when the remaining capacity of the memory for facsimile comes to a predetermined capacity. Grouping can be carried out based on the telephone numbers of senders and the like during rearrangement of facsimile data.

摘要： A scanner is so arranged that a quantity of light reaching a CCD sensor can be kept constant with a change in reading position. In case a light source and a reading optical unit are driven independent of each other, variations in feed amount inevitably occur. To deal with it, a test chart of a specified length is first read to measure moving amounts of the light source and the reading optical unit. Then, the reading optical unit is moved by a predetermined amount. The light source is moved as effecting a correction based on the moving amounts initially measured. Then, a one-line reading process is carried out to scan an image on a document.

摘要： A reader for reading light reflected from or transmitted through an original document includes an adjustment apparatus for detecting the white level of an analog signal from the original document. The detection is performed before reading of the original document. The detection level is compared to a reference white level. In response to the comparison either clock signals to an image sensor or a lighting signals to a light source are varied so that any analog signal from a read document has the reference white level.
