Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording apparatus that records an image on a recording medium using a light emission pattern of a phosphor.

As the 7th grade in the field of printers.

Various printers are known, such as laser printers, OFT printers, LED printers, and optical shutter array printers. Among these printers, the laser splitter requires a movable mechanism such as a polygonal high-speed rotation mechanism, which has the disadvantage that the set optical system becomes complicated. In addition, for OF'T (optical fiber cheese) printers, it is necessary to avoid increasing the size of the device and to accurately manage the minute gear knob between the recording surface and the end face of the fiber tube. Furthermore, in LED printers, it is necessary to connect a large number of LED chips in one direction or to arrange the strips in a staggered manner, which makes the LED light emitting elements themselves expensive and increases the light emission distribution. In addition, in optical shutter array printers, when PLZT or the like is used as a crystal device, the same drawbacks as those described in connection with LED printers occur.

It is an object of the present invention to provide a new recording device which eliminates the drawbacks of the conventional example, is low in cost, and can be made extremely compact.

Hereinafter, the recording apparatus of the present invention will be explained with reference to the illustrated embodiments. and an imaging element that forms an image on a recording medium using the emitted light pattern as imaging light. First, the scanning recording element will be described below.

By the way, it is already well known that a fluorescent display chamber is used for Nice Play, but the present invention is based on a luminescent display mechanism of a fluorescent substance, and the present invention is a light display chamber for photo printers. This is developed into a smooth output element, and this is used as a basic configuration to be applied to the intended recording device.

Figure 1.1 shows a plan view of a scanning recording element included in one recording device, and Figure 2 shows an enlarged view thereof.

Figures 3 and 3 show a side sectional view of the scanning recording element, and Figures J and 4 show a perspective view of the scanning recording element.

In Figure 3 and Figure J-1, the scanning recording element l is
A light shielding part @5 is provided on the substrate glass 3. Next, a transparent electrode array 6, a phosphor 7. A grid electrode 8 and a -% filament 9 are provided in this order toward the face glass 4,
In addition, the solar cell is housed in an inner seal formed by a substrate glass 3 and a face glass 4. Incidentally, in the scanning recording element shown in Figure 4, the openings at both ends are connected by a first side plate (not shown).

The light shielding member 5 is thinly coated on the substrate glass 3, and this light shielding member 5V'C is provided with a minute slit opening 5a of, for example, about 100 μm to 5°.

The opening 5a is parallel to the main meal direction A (see figure "A'4").The transparent electrode array 6 consists of a single fine rectangular transparent electrode 6a as shown in figures 3 and 2. 6
b are arranged alternately in an array in the main direction, and the apertures 5a mentioned above are arranged in the transparent electrode 6.
It intersects a and 6b at right angles.

The phosphor 7 is in the form of a tongue disposed in the direction of the main feeding force and is adjacent to the transparent electrode array 6.

In this actual example, the phosphor 7 is coated with a transparent layer on the polar array 6 by, for example, a printing method.

Then, such a laminated film is sealed off from the rear part by the face glass 4.

The slit opening 5a of the light shielding member 5 of the scanning recording element 1 configured in this way allows the transparent electrode array 6 and the light emission of the phosphor 70 to be arranged in the main scanning direction, for example, in a small area of approximately square shape. The scanning recording element 10, which has the function of obtaining and scanning light emitting dots, performs recording by imaging the light emitting pattern taken out from the substrate glass 30111 onto a recording medium via an imaging element. A desired information image can be recorded on the medium. In this case, the moving direction of the recording medium is the sub-scanning direction B which is perpendicular to the main-scanning direction A in FIG. Note that details regarding fl and ic will be described later.

The OFF diagram and Figure 8 show an example of the configuration of a driver circuit for functioning as a light emitter of the main scanning recording element. By first controlling the electric power applied to the divided grid and the transparent electrode corresponding to each light emitting dot by the driver 72.13, the voltage applied to each divided grid is sequentially
It is designed to emit light and give off a turn. for example,
If you want to make the first dot in the Qn region emit light.

It is sufficient to apply the J1 positive potential to Qi and Φ1.

In this way, in this example, light emission is controlled by a combination of dynamic pulses on the divided grid electrodes and driving of individual electrodes.

In the example shown in FIG.
'By applying a breakdown voltage, the light emission of the scanning recording element is controlled. In this case, each transparent type 1 blood uj
A voltage is applied to the driver circuit 14. or more preferably, the driver circuit 14. 15. 16K
Apply voltage to each transparent electrode.

Now, in such a light emission control thread for scanning recording, the generation of information light for scanning recording, that is, the light emission of the phosphor is performed as follows. First.

Electrons that fly out from the cathode usually head toward the grid that is negatively applied or the anode that serves as an anode, and do not reach the phosphor located between the grid and the anode, but are directed toward the electrode corresponding to a specific dot. When a predetermined potential is first applied by the voltage application control system as described above, electrons from the cathode fly toward the anode, and a selective portion of the phosphor located in the middle of the electrons is excited. It emits light. This light emitting pattern 7 becomes long in the direction orthogonal to the main scanning direction due to the influence of the electrode shape, and has the width of the electrode in the main scanning direction. However, due to the slit opening 5a of the light shielding member 5, the light emitting pattern is restricted in the direction orthogonal to the main scanning direction, and the light emitting pattern seen from the substrate glass 3 is close to the desired dot shape. Become something.

In order to accurately set the shape of such a luminescent dot.

As shown in FIGS. 3 and 5, a light shielding member 11 may be used in which minute apertures 11a are arranged in an array in the main scanning direction. Although we have described a configuration in which the light-emitting pattern is taken out from the substrate glass 3 side, it is also possible to knead it from the cathode filament 9 side, and in this case, it is possible to knead the light emitting pattern from the cathode filament 9 side. Same as for use
This is the configuration.

Figures 1 and 6 show an example of a scanning recording Yonago in which a light emitting turn is taken out from the face glass 17 side, that is, from the cathode filament 9 side. The glass 17 is parallel to the substrate glass 3 and similarly has a smooth surface. An electrode array 6 with metal electrodes as electrodes is provided on the substrate glass 9-glass 3, and then a phosphor 71, a light shielding member 51, a cathode filament 9
The structure is such that the sunnets are arranged in the following order.

By means of this scanning recording element, the light emitting pattern can first be taken out from the cathode filament 9 side.

In this example, an opaque ordinary metal electrode is used instead of the transparent electrode used in the previous example.

Further, the light shielding member 5 is provided adjacent to the phosphor 7. In addition, in this scanning recording Yonago, there is no problem in using transparent electrodes as the electrodes, and in this case, light emission and turns can be taken out from both sides of the scanning recording element. It should be noted that the driver open side J system shown in the off diagram or Figure 8 is also used in this scanning recording Yonago.

By the way, as in the actual examples shown in Figures 3.7 and 3'8, when scanning one line and recording one line by dividing drive, the light emission time per l dot is set to be multiplied by the number of divisions. Therefore, it is possible to reduce the burden of light emission brightness during fidgeting. In addition, when emitting light at the same time (pulse time) for each lG- divided block (the scanning recording time for one type is 1/1 of the number of divisions, the recording speed is increased by 1]) This is a CRT line recording system that performs raster scanning ('i), which can achieve a high-speed recording function that cannot be underestimated.

]・Figures 9 and 12 show examples of printing apparatuses using the above-mentioned scanning recording element.The printing apparatus shown in figures 1 and 9 uses the scanning recording element shown in figure 6. A roof mirror lens array 18 is used as an imaging element. Further, a drum-shaped photoreceptor 19 is used as a recording medium.

In the first recording apparatus constructed in this way, the light emitted from the scanning recording element 2 is image-formed onto the surface of the photoreceptor 19 via the Tano mirror lens array 18, and the photoreceptor is In this case, the photoreceptor 19 is moved in the sub-setting direction (indicated by symbol B) perpendicular to the main scanning direction described above.1.1
At the end of the recording device shown in Figure 0, A = 3 as a scanning recording element.
The type shown in the figure is used. The ML recording device shown in Figures 1 and 11 and υ and Figure 12 is one in which the type of scanning recording element is changed from that 1, and the type of scanning recording element is changed from that, and an optical beam transmitter array 21 from the Song Dynasty is used as an imaging table. .

In addition, this is compared to an optical ridge carrier array using a Tahamira/Zuarray as an imaging element.

Since there is little chromatic aberration, there is an advantage that the wide spectral range of the phosphor can be used as is. In addition, since the Tahama mirror lens array has a deep focal depth, the vertical setting tolerance in the n-direction of the recording medium is wide, resulting in a good h
It's said that you can write down one of your personal records! There are I and Q.

In addition, the boroprism lens array described in % Application No. 56-184845, which was previously filed by the applicant, may be used as the Yuizuka thread.

Note that the imaging element and the recording medium are not limited to the above-described embodiments, and may be replaced with other devices that achieve the same function.

In addition, in the above-mentioned recording device, the scanning recording element is fixed and the recording medium is moved, but in contrast to the kneading method, the recording medium is fixed and the scanning recording element is moved. It's okay. Incidentally, five-line scanning: The recording element can also be applied to a display tube type one.

By the way, the recording apparatus Q'j of the present invention: As can be understood from the above explanation, the use of a fluorescent display element is
The various effects of using such an element are summarized as follows.

l) Since it is a complete solid-state meal recording method, it does not require a movable mechanism such as a polygon used in a laser printer.

2) Since the scanning optical system requires a smaller configuration than a laser prism/reflector, the device itself can be made smaller and lighter.

3) There is no need to connect each chip as in the case of using a crystal device such as an LED array, and it is possible to make a set meal confectionery into a long integrated one.

4) By adopting a divided simultaneous drive method for the drive circuit, the light emitting time of a single dot (k light time) can be set longer than that of a CRT recording method that performs raster scanning. , the burden on luminance can be further reduced. Furthermore, if each divided block is emitted at the same time, the scanning time of 1917 minutes is reduced to one divided by the number of nuclei, so high-speed scanning becomes possible.

5) Compared to LEDs, the luminous efficiency is much higher than that of LEDs, so power consumption can be reduced, and the amount of heat generated is extremely small.

6) The normal lighting source of Keukoukanji Temple is not used for the light source such as Light Array Puri, and there is a problem with its lifespan.
The present eclipse recording element can eliminate such points and achieve a δL menote-free function.

In addition, various effects of each embodiment are as follows.

l) Since the size of the light-emitting dots is set using individual electrodes and slit openings, continuous slit printing is performed as a phosphor, making it extremely easy to process set meals.

2) By using transparent electrodes as the electrodes of the scanning recording element,
The light emitting pattern can be taken out from the substrate glass side,
In this case, there is no possibility that the luminous flux will deviate or fluctuate due to the cathode filament, grid electrode, face glass, etc., and the luminous flux can be efficiently guided to the outside.

3) By configuring the light-shielding member to have a minute aperture 11a as shown by the symbol [■] in Figures 3 and 5, it is possible to regulate the light-emitting F throat to the shape of Kusunoki, and to prevent so-called crosstalk. It can be less.

4) The scanning recording element is configured as shown in Figure 6, and one light emitting pattern is printed from the smooth face glass 17 side.
The part that slides out is a normal display configuration, with the phosphor 7
The luminous flux from the surface of the phosphor that is hit by electrons is directly used, and the efficiency of light utilization can be further increased.

5) As for fluorophores, regarding spectroscopy A/Lugi special attack,
Various types are available over a wide range and therefore have good compatibility with the spectral sensitivity of the recording medium.

As described above, since the recording apparatus of the present invention uses an inexpensive, extremely compact, and long integrated scanning recording element having a self-luminous function, it is possible to make the recording apparatus itself extremely small in size, and it can also be made less bulky. In addition, it is also possible to achieve the function of reducing power consumption.
