4 Sheets-Sheet 4 PICTURE AND WRITING RECORDER USING- BALL-PEN SYSTEM SUMMARY OF THE INVENTION Since old days various systems for recording pictures and writings have been developed and now are in general use widely. With the advancement of information system in society, the demand for transmission of pictures and writings including facsimile is on the gradual increase. However, the picture and writing recording systems which can be presented to the practical use have a lot of defects and can not withstand the use of general demanders.
1. The cost of receiving part is high;
2. Special electrostatic recording paper, field destroying paper, sensitive paper and the like are required for the receiving recording paper, and thereby the cost for handling comes into question;
3. In the present facsimiles there is none which can perform in a simple method recording of color pictures and writings.
This invention relates to a picture and writing recorder in which such defects are not found.
The first feature of this invention is to provide a transmitting part and a receiving part of color facsimile. Said transmitting part is provided with a cylinder with a original subject copy on its surface driven by a motor, each set of photoelectric converter and amplifier for each primary color of said original, for example, cyanine, magenta, yellow and black, and an encorder to multiplex said primary color signals and a synchronizing signals from a speed senser of said rotating cylinder. And said receiving part has a decorder which restores the received signals to said primary color signals and said synchronizing signals, a drum with some paper on its surface driven by a motor, an AFC device which synchronizes the rotation of said drum with that of the cylinder of the transmitting part by comparing the signals from said senser with said synchronizing signals, each set of amplifier and recording part for each of said primary color. signals. Accordingly it is possible to transmit and record colored pictures and writings easily' by using cable or wireless apparatus.
The second feature of this invention is to use in said recording part a ball-pen system utilizing a pen having a ball at its point and to support a holding means for said ball-pen so to be pressed to a paper with some pressure corresponding to the strength of said each primary color signal led from said decorder and amplified. One
'of these mechanisms resembles to the cone driving part of a moving coil-outer magnetic type speaker, and the other resembles to the cone driving part of a moving coil-inner magnetic type speaker. By these mechanisms said pressure changes corresponding to the current flowing through said moving coil, and as the result, the same contrast is attained on a paper as that of said original subject copy at the transmitting part and an excellent transmission recording of color picture and writing is easily obtained.
The third feature of this invention is to coat the surface of a supporting base of the recording paper in the receiving part with a vinyl or rubber sheet so as to facilitate recording by said ball-pen and to provide an excess ink eliminating mechanism such as felt or brush unit in the receiving part.
The other features of this invention will become clear from the explanation of one embodiment of this invention shown in the accompanying drawings.

DETAILED DESCRIPTIONOF THE INVENTION:
An example embodying the present invention will be explained with reference to the accompanying drawings. FIG. 1 illustrates an example of a block diagram in which the present device is employed. Reference numerals 1 through 18 in FIG. 1 designate a transmitting part of a color facsimile. Referencenumeral 1 designates a cylinder on the surface of which a original subject medium 2 is attached, and the cylinder is rotated by means of a motor 3 through a driving shaft amplified and shaped by amplifiers ll, 12, Band 14,
and thereafter led to an encorder 15.
The encorder l5 time-divides or multiplexes each primary color signal, and, on the other hand, a synchronizing signal from a phase transmitter is added. Said phase transmitter comprises a gear-like disk 16 made of .a soft iron for showing a cylindrical rotating phase and directly connected to the cylinder, and a senser 17 for sensing said disk.
The multiple or time-division methods in the encorder l5'has been widely known, and most of the types of synchronizing signals are publicly known, for example, by U.S. Pat. No. 1,709,926. Furthermore, since the encorder itself has no great relationship with the essence of the system of this invention, it is omitted to describe it in detail.
3 Now, the signal thus taken out is led from the encorder to a transmission terminal 18 and sent out by a transmission medium 19 such as a wire orwireless system. Y
The photoelectric converters 7, 8, 9 and 10 are fabricated such that they migrate in the axial direction of the cylinder with the rotation of the cylinder 1.
Reference numerals 20 through 36 in FIG. 1 designate the receiving part of a color facsimile which includes a recording part in ball-pen systemhaving a characteristic of the present invention.
Firstly, the primary color signal multiplyed or timedivided is led from a receiving terminal 20 to a decorder 21. The multiplyed signal or time-divided signal is restored to each primary color signal or synchronizing signal which is original signal in the decorder. With respect to the types of the decorders, since there are many publicly known ones as in U.S. Pat. No. 1,709,926 corresponding to the types of the encorders, and therefore explanation in detail thereof will be omitted.
The synchronizing signal which forms one of the output of the decorder 21 is led as a standard signal to an AFC device 34 for rotating a drum of the receiving part in synchronism with the rotation of a cylinder 1 of the transmitting part. Signals from a senser 33 for sensing the phase of a soft iron-made gear-shaped disk 16 of the transmitting part directly connected to the drum 30 and showing the rotation phase of said drum and that of a similar disk 32 are applied to the AFC device 34. The output from the senser 33 is compared with the synchronizing signal from the decorder 21, and taken out of the AFC device 34 as such a signal that the phase of the drum of the receiving part synchronizes with the phase of the cylinder of the transmitting part, and a motor 35 for driving the cylinder is rotated by this signal. The rotation of the motor 35 is transmitted from a drive shaft 36 to the drum 30.
As already explained, other outputs from the decorder are restored primary color signals. These four signals are amplified by amplifiers 22, 23, .24 and 25, and applied to recording parts 26, 27, 28 and 29 arranged on the drum of the receiving part, thereby to drive the ball-pen type recorders of the recording'parts respectively. These recording parts move in the axial directionof the drum 30 with the rotation of the drum 30.
Respective ball-pen type recorders of said recording part have inks corresponding to the spectral characteristics of respective primary color photoelectric converters, and are press-fitted on a general paper 31 wound around the surface of the drum 30 by primary color signals. Thereby a transmitted signal of the original subject copy is recorded with the density of each primary color ink corresponding to the density of respective primary color of the original subject copy on a general paper or a sheet of other material 31, thus the colored picture and writing recording being carried out.
This block diagram illustrates the principle of this system. With respect to the actual device, the picture and writing recording starting signal and stopsignal are issued from -the transmission side and the starting, stopping and resetting of photoelectric converters 7, 8,
9 and 10 and receiving recorders 26, 27, 28 and 29 are controlled in accordance with these signals. Furthermore, when the only black printing portions of these photoelectric'converters and recorders are used, black and white facsimile can be obtained.
One example of the ball-pen type recording which is the main point of the present invention will be illustrated. FIG. 2 (A) is a view showing an appearance of a ball-pen system recorder. FIG. 2 (B) shows the section of the same.
In FIG. 2 the recorder resembles to the cone driving part of a moving coil-outer magnetic type speaker. Reference numeral 37 designates a magnetic yoke, and forms a magnetic path together with a permanent magnet indicated by numeral .38 and produces a strong magnetic field perpendicular to a moving coil 40 retained by a diaphragm-shaped cone 39. Since the diaphragm-shaped cone has an elasticity in the axial direction, it is displaced in the axial direction corresponding to the current flowing to the moving coil 40. The signal current of an amplifier 22 (or 23, 24, 25) in FIG. 1 is applied to the moving coil 40. The diaphragm-shaped cone is secured by a vibrating plate fitting seat shown by reference numeral 41. On the other hand, a ball-pen retainer 42 is fitted to the center of the diaphragm-shaped cone thereby to hold a ballpen 44 with a teflon bushing 43. The ball-pen is secured by means of the ball-pen retainer42, and since the teflon bushing 43 can move the pen in the axial direction, the pen 44 migrates in the axial direction by the current flowing on the moving coil 40, and, as the result, it is press-fitted on a general paper 31 wound around the drum 30 of the receiving part. The interval between the pen point and paper surface is retained to become constant at the time of non-signal by an interval retainer indicated by reference numeral 45 in FIG. 1. By these operations, when a current flows on the coil, the ball-pen receives a displacement according to the current, and the ball portion of the pen is pressfitted on the paper face. By the degree of this pressfitting the area of ink printed on the paper surface vary 2 ciple of the present invention, and it is possible to obtain many modifications therefrom. For example, an ink retaining portion of a ball-pen is connected to an ink reservoir, arm is drawn out of the yoke as a method of retaining the interval of the paper surface and the pen point, and the entire part of a recorder. is pressfitted to the paper surface. In place of a similar mechanism to the cone driving part of the moving coilouter magnet type speaker, a similar mechanism to the cone driving part of the moving coil-inner magnet type speaker or a recording mechanism similar to the mechanism of the cone driving part of the magnetic speaker shown in FIG. 4 can be obtained. In FIG. 3
there is shown an example of the assembling method of the recorders.
Furthermore, it is preferable to coat the surface of the drum of the receiving part with an elastic sheet of vinyl, rubber and the like so as to facilitate recording by the press-fitting of the ball-pen.
Since said coating of the base which is supporting the recording sheet is one of the most important parts in this invention, it will be described in detail. In FIG. 7 and FIG. 8, the rotation among the ball of the pen tip, the coated surface and the result of recording are shown.
In FIG. 7, reference numeral 94 shows a holding part of said ball at the ball-pen, 95 shows the ball, and 96,97,98 show respectively a recording sheet, a vinyl or rubber sheet and a supporting base. For example, 96,97 and 98 are supposed to illustrate the cross-section of the recording sheet setting on the vinyl sheet whic winds around the drum.
FIG. 7 (A) shows the situation that the tip of the ballpen is apart by so small distance from the recording paper.
FIG. 7 (B) shows the situation that the tip of the ballpen is slightly pressed to the surface of the recording paper and as the result, the vinyl sheet fixed under the recording paper is pressed as the shape of small concave. Then the pen is started to record on the paper.
FIG. 7 (C) shows the situation that the pressure is increased, in consequence, a bigger concave is made on the original subject copy becomes possible to be realized.
In the FIG. 7 (D), furthermore, the pressure applied to the ball-pen becomes the maximum and the tip of the ball goes into the recording paper up to the deepest point. In this way, the touched area between the ball andthe paper increases to the maximum and it corresponds to the highest density portion on the original subject copy. The strength of signal applied to the ballpen responds mainly to the variation of the width of the recording line.
This is the remarkable feature of this invention.
There has been no method like the one above mentioned for expressing wide range of density. The relationship between the depthof press-fitting and the width of recording line 99 is shows in the FIG. 12. In other words, the levels of press-fitting depth, a, b, c, andj respectively correspond to the width of recording line a, b, c, and j, the recording line for the lighter-tone portion on the original subject copy is shown narrower, for example, b, and the darker-tone portion on it is shown wider, for example,j'.
In such a way, almost full range of density on the original subject copy becomes possible to be expressed continuously.
Still further, in order toeliminate excess ink adhered to the pen point, an excessive ink eliminating mechanism such as a felt or brush 45 may be provided at the time of starting recording as shown in FIG. 5(A) or in a predetermined phase period of the rotary drum in a direction of the rotation of the drum or that perpendicular to the rotational direction as shown in FIG. 5(B). The ball-pen mechanism is shown in FIG. 6. It is evident that the picture and writing recording device using the aforementioned ball-pen system is very cheap as compared with the conventional device and simple in handling and easy in color recording. According to experiments, it is ascertained that images of high quali ty can be obtained. In FIG. 6 reference numeral 49 designates a ball, 46, an equipment for retaining the ball to which an ink holder designated by reference numeral 47 is fitted, and reference numeral 48 designates ink.
