Definitions
- the present invention relates to an apparatus for scanning / copying originals.
- it relates to a device with which each point of an original can be scanned or scanned simultaneously, ie the scanning or scanning of the original takes place in parallel instead of in series.
- it relates to an apparatus that includes a reproduction ⁇ device which makes it possible to display the scanned image of the original with the device itself.
- CCD lines as the active optical element.
- the originals are usually illuminated line by line by a cold light lamp and the reflected light is directed to a sensor via optics.
- These optics usually consist of at least two movable deflecting mirrors and a lens, which means that the reflected light from the original may even be directed to the fixed or movably installed CCD sensor in a reduced size.
- it must be ensured that the path that the light travels through the movable mirrors to the sensor is of the same length at every point of the original.
- This conventional scanner design has several disadvantages.
- the system requires a larger number of optical components (mirrors, lenses, cold light lamps, CCD) and complex mechanics for the exact movement of the optics.
- This structure takes up a lot of space in the device and the complicated mechanics are expensive to manufacture. It is also prone to wear, and misalignment can occur, which can degrade image quality over the course of its lifetime.
- the reduction in the size of the image of the original also has an adverse effect on the theoretically possible quality of the image when it is subsequently required to be enlarged. Due to the Movement mechanics of the scanner also takes a certain time for the scanning process, which depends on the speed at which mirrors and lamps have to be moved past the original; not to mention the background noise that may be experienced as unpleasant when working with the device.
- LED scanners are a further development. These devices use a reading line made up of light-emitting diodes and CMOS sensors instead of the CCD line and cold light lamp. The complicated mirror mechanism is not necessary. In addition, no lenses are required, since the LED lines usually go across the entire width of the document support. Such reading lines can be built very compactly and contain all the electronics required for image acquisition. With this type of scanner, the mechanics only have the task of guiding the reading line device past the template. Advantages of this type of scanner are the comparatively low manufacturing costs of the reading lines with inexpensive semiconductor components, the relatively simple mechanics and the possible very flat construction. In addition, the mechanics' susceptibility to wear is drastically reduced, and the optics are not adjusted because all the necessary elements are integrated in the compact reading line.
- Has mechanics and which enables a quick reading of a template.
- the scanned image should be able to be displayed in real time with the device itself without the need to use additional devices.
- Other features should be a lightweight, very compact design and low energy consumption.
- the present invention is based on the idea that a device for scanning or copying is made available which has a reading and a storage device made of organic semiconductor components. These organic components (OBDs, OLEDs, photodiodes and the like) are just as inexpensive to manufacture as they are lightweight, energy-saving and extremely compact.
- the storage device is capable of storing the scanned image.
- the reading device extends over the entire original support (ie width and length), so that a simultaneous scanning of each point of the original is made possible.
- the device reads in parallel, whereas conventional scanners read in serially.
- a playback device is made available which makes it possible to store the data stored in the storage unit Display the image of the template directly and without additional devices with the scanner / copier itself.
- OLEDs organic light-emitting diodes
- organic displays as well as organic solar cells and photo detectors.
- the latter basically consist of thin organic films that are stored between two electrodes. If light falls through the transparent electrode, organic light is generated
- a voltage between the electrodes can now be tapped via a resistor.
- OBDs Organic Bistable Devices
- a device which is intended for scanning or copying originals.
- the device has an original support on which an original can be arranged for the purpose of scanning.
- the device has a reading device which is intended for scanning the original.
- it has a storage device which is constructed from bistable organic components and which stores the scanned original image.
- the bistable organic components have alternating layers of organic material and electrodes, which are made, for example, of metal or an organic conductive material.
- the reading device is made up of organic photodiodes.
- the light-sensitive photodiodes are used for optical scanning of the original.
- Organic photo diodes ⁇ are basically made up of an organic film between two electrode layers.
- the reading device contains a template illumination which is constructed from organic light-emitting diodes.
- the original illumination illuminates the original so that the reading device can record the light reflected from the original.
- Organic light-emitting diodes are basically made up of an organic film between two electrode layers.
- the reading device extends over the entire area of the original support, ie both over the entire length and over the entire width.
- the ⁇ be indicated that each element that is, each photodiode of the reading device is associated with a correspondingly large point of the original support. The purpose of this is to scan each point of the template at the same time. In other words, this is done to do a parallel scan, as opposed to a ner serial, in which all points of the template are scanned one after the other.
- the storage device is arranged congruently with the reading device.
- a bistable organic component of the memory device is assigned to each photodiode of the reading device.
- the storage device is arranged essentially coplanar with the reading device.
- the device contains a display device which is made up of organic light-emitting diodes.
- the playback device is used to view the scanned image.
- each bistable component (OBD) of the storage device is assigned an organic light-emitting diode (OLED) of the playback device.
- OLED organic light-emitting diode
- the original pad is a touch pad (so-called touchpad).
- FIG. 1 shows an embodiment of the device 2 according to the invention.
- the distances between the three layers, which each belong to a reading device 6, a storage device 8 and a playback device 12, are not reproduced to scale for better clarity.
- the necessary connections of the reading device 6 to the storage device 8 and the storage device 8 to the playback device 12 are not shown.
- a template V is shown, which is arranged on a template support 4.
- the organic light-emitting diodes which form a template illumination 10 are also contained in the layer of the photodiodes which form the reading device 6.
- the template to be scanned is first illuminated by the OLEDS, which are integrated in the reading device 6.
- the reflected light falls on the photodetectors of the reading device 6 and generates a voltage therein.
- the OBDs of the memory device 8 are switched from their high impedance state to the one with a lower resistance, depending on the brightness of the light captured. Since the entire template is captured at once when the image data is read in, this parallel architecture reduces the time required for reading to a fraction of the time required by conventional technologies.
- the image of the template is thus retained in the organic components of the storage device 8.
- each OLED of the display device 12 is driven in accordance with the state of the associated bistable memory cell.
- the reproduction device 12 reproduces the image which is stored in the storage device 8.
- the operating mode described enables scans and copies with a gray level.
- By scaling the capacity of the photodetectors of the reading device 6 for example by different layer thickness, a grayscale subdivision can be realized. It should be clear to those skilled in the art how color scanning and reproduction can also be achieved with the invention using known methods.
- bistable cells with organic photodetectors and organic light-emitting diodes enables the design of original scanners and copiers, which due to their light weight, low power consumption and compact dimensions can be used practically anywhere.
- the structure of such a device has three layers.
- the bottom layer (the reading device 6) consists of organic photodiodes and possibly an integrated template lighting 12 (OLEDs).
- OLEDs integrated template lighting 12
- the storage device 8 made of bistable organic cells.
- the graphical representation of the stored information takes place through a further layer of organic light-emitting diodes, which form the reproduction device 12.
- the layers are of pixelated construction, with each photodiode of the reading device 6 being assigned a bistable organic component of the storage device 8 and an organic light-emitting diode of the reproducing device 12.
- the main advantage of this setup is the ability to display the stored data on-site on the device so that, for example, the quality of the scan can be assessed immediately. No other device such as a computer, and therefore of course no software required.
- a fundamental advantage of the device is also the practically complete noiselessness due to the lack of any mechanical system.
- the layered arrangement of reading device 6 (with integrated template lighting 12), storage device 8 and playback device 12 makes it possible to produce the three devices inexpensively and simply in one unit. The necessary connections are kept as short as possible.
- the reading device is connected to the Device connected to which it can transmit the scanned image.
- the storage device is connected to the display device to which it can send the stored image.
- the template pad 4 would have to be replaced by a transparent touch field (a so-called touchpad). It should still be possible to manipulate the saved image using the touchpad.
- the image shown by the playback device can then be corrected in this way, i.e. copied donkey ears, hole corners, dirt particles, coffee stains and the like could be erased ". Or handwritten notes could be added to the picture.
