Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a board with a printer used at conferences and the like.

Conventional structure and problems Conventionally, with this type of board, it was not possible to save the content recorded on the board surface, and if it was necessary to preserve it after use, it was necessary to transcribe it or record it with a camera, etc. It was common practice to take pictures and save them. However, when copying by hand, mistakes or oversights often occur, making it difficult and time-consuming to convey the content accurately, and taking pictures with a camera also poses problems when attempting to copy the content of the meeting at a later date. There were also problems such as the need to prepare photographic equipment at the meeting table.

In response to this, in recent years, devices have been proposed that allow the recorded content on a board to be output as an image on a display tube, or that can make a copy of the recorded content. However, in the case of the former, a large number of contact points are placed on the board surface, and the device is read in a straight line as an electrical signal during recording, resulting in an extremely expensive device (sales price of several million yen); Since the content is specularly reflected, focused by a lens, and read by a CCD, etc., setting the focal length of the light is important.
Furthermore, an extremely strong structure is required to prevent distortion from occurring. Therefore, it had to be heavy and expensive.

Purpose of the Invention The present invention solves these conventional problems and provides a board with a printer that can copy and save the contents of meetings, etc. recorded on the board surface in a simple and inexpensive manner. .

Structure of the Invention The board with a printer of the present invention is provided with a reading device on the back side of the board made of an infrared transparent material, which takes out an image recorded on the front side of the board as an infrared signal, and this reading device has an infrared signal that is read out. One end of a group of optical fibers that transmits the The image is transmitted as infrared transmitted or reflected light using the group of optical fibers, and the recorded contents are copied onto paper by a printer via the infrared detection device.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a board made of an infrared transparent material such as ceramic, resin, etc., and is used to record meeting minutes and the like on the front surface of the board. 2 is a reading device, which is automatically moved on the back side of the board by a drive source such as a motor (not shown) as shown by the arrow in the figure, and extracts images such as characters recorded on the front side of the board as infrared signals. It is something. Reference numeral 3 denotes a group of optical fibers for transmitting infrared signals read by the reading device 2, one end of which is placed at the reading device position to receive the infrared rays on the back side of the board. Reference numeral 4 denotes an infrared detection device provided at the other end of the optical fiber group 3, which converts infrared signals into electrical signals. Reference numeral 5 denotes a printer capable of copying the content read by the reading device 2 onto a recording paper 6 connected to the infrared detection device 4.

FIG. 2 shows the internal structure of the reading device 2, in which 7 is an image such as characters recorded on the front surface of the board 1, 8 is a light receiving section, 9 is an optical fiber,
10 is the exterior of the reading device 2. In the configuration shown in FIG. 2, the infrared rays that have passed through the image 7 are transmitted through the board 1 along the dashed arrow in the figure and enter one end surface of the optical fiber 9.

FIG. 3 shows another embodiment, in which an infrared light emitting device 11 is built into the exterior 10 of the reading device 2, and the infrared light emitted from the infrared light emitting device 11 passes through the board 1. It is reflected by the image 7, passes through the board 1 again, and reaches one end surface of the optical fiber 9.

FIG. 4 shows the processing state of both ends of the optical fiber group 3, and reference numeral 12 indicates the processing state of the optical fiber group 3.
This is an input end surface in the reading device 2. As shown in the figure, single optical fibers are arranged in a line. Similarly, 13 is the output end face of the optical fiber group 3 within the infrared detection device 4, and here the optical fiber group 3 is converged into a rectangular shape. In the infrared detection device 4, the input infrared signal is converted into an electrical signal and transmitted to the printer 5 through the cable 14.

In addition, in the figure, for explanation, reading device 2,
Although the infrared detection device 4 and the printer 5 are shown as separate bodies, they may be configured as one body.

To explain the operation of the above configuration, the input end faces 12 of the optical fiber group 3 are arranged in a line in the reading device 2 as shown in FIG.
Therefore, the infrared rays that pass through or are reflected by the image 7 recorded on the front surface of the board 1 are transmitted to the optical fiber 9 as strong and weak infrared signals,
Image signals from a narrow strip in one vertical row on the front surface of the board 1 are transmitted to the input end face 12 of the optical fiber group 3. This image signal is converged into a rectangular shape at the output end face 13 of the optical fiber group 3, and converted into an electric signal by the infrared detection device 4. Then, the image signals are rearranged in the printer 5 into one line of band-shaped image signals, and then copied onto the recording paper 6. By repeating the above operations and sequentially moving the reading device 2 over the back surface of the board 1,
It is possible to copy the entire image recorded on the front side.

Effects of the Invention As is clear from the above embodiments, the board with a printer of the present invention reads the content recorded on the front side of the board as an image signal as an infrared signal from the back side of the board, and immediately copies this onto the recording paper of the printer. Because of this structure, there is no need for a large-capacity memory element to store the entire board surface.
By simply synchronizing the moving speed of the reading device on the back surface of the board and the feeding speed of the recording paper of the printer, it is possible to copy the recorded content on the board surface extremely easily and inexpensively. Furthermore, since optical fiber is used to transmit the image signal, it is not affected by external disturbances, and the position and shape of the infrared detection device can be set freely, providing a large degree of freedom in terms of structural space. Since there is no lens condensing, etc., there is no need for a highly rigid structure. Furthermore, since it uses infrared rays, it is possible to place the reading device on the back side of the board, making it very clean as a whole, making it extremely practical. .
