[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a whiteboard with a copy function used in meetings, etc., and in particular to an electronic blackboard suitable for reading images written on manuscripts and displaying them on the board. Regarding the equipment. [Prior Art] A whiteboard with a copy function has the function of copying an image written with a felt-tip pen or the like on a board of a size normally installed in a conference room onto recording paper. It is called a whiteboard because the board is white, and it is also called an electronic blackboard because it is a blackboard that reads and copies images electronically. This type of device is similar to a blackboard that uses a normal solid powder object (chalk) to write on a large board and make it visible to others, but it is possible to write on a large board and make it visible to others. The difference is that it eliminates the need for participants and scribes to copy the board image by copying the board image as needed to record the progress of the meeting or distributing it to the participants of the meeting. ．．
In addition to writing directly on the board with a felt-tip pen, you can also read manuscripts such as handwritten documents and general printed materials and write them on the board, which is not limited to handwritten images.
It was also possible to display normal manuscripts on the board. Conventional devices that achieve functions not found on ordinary blackboards mentioned above are:
As described in Japanese Patent Application Laid-Open No. 61-47300, the size of the board did not change. [Problems to be Solved by the Invention] ■ In the above conventional technology, once the device is configured, the size of the display board that displays the original image obtained by writing or reading the handwritten image does not change, so it cannot be used in a narrow space. The device may be too large and difficult to use;
When a large number of people hold a meeting in a large space, there is a problem in that the images written or displayed on the display board are too small to be seen, reducing the efficiency of meeting management. ■ In the above conventional technology, the number of pages on the display board is configured to be constant, and if the image written on the document is larger or smaller than the size of the document, the image is written on a large or small size document. There was a problem in that it was not possible to read a written image or to have space next to the displayed image. ■ This type of equipment is
It is usually installed and used in a conference room, but because of its very convenient functions, it can be easily used in various places, such as a meeting with 2 or 3 people near an office desk, a conference room far away, etc. There are many requests to use it.

The problem was that groups could not be used.

■ In the above conventional technology, the operation panel that issues various operation commands is integrated with the device, so when attendees give explanations using the display board, it is necessary to display other pages on the display board or change the board image. There was a problem in that one had to move close to the device to issue commands such as making a copy. ■ In addition to manuscripts such as handwritten materials and general printed materials,
If normal three-dimensional objects such as telephones and copiers could be displayed on a board, it would make meetings easier, but there was a problem that conventional equipment configurations could not handle this. A first object of the present invention is to provide an electronic whiteboard device in which the size of the display board changes continuously. A second object of the present invention is to provide an electronic whiteboard device in which the number of pages on the display board changes. A third object of the present invention is to provide an electronic whiteboard device that is easily portable.A fourth object of the present invention is to provide an electronic whiteboard device in which both the front and back surfaces of the device can be used as display boards. It's about doing. A fifth object of the present invention is to provide an electronic whiteboard device in which an operation panel is removable from the main body of the device. A sixth object of the present invention is to provide an electronic whiteboard device that can input an image signal from a video camera and record it on a board display or recording medium. [Means for Solving the Problems] In order to achieve the first objective described above, a display board that can be written on with a writing instrument, a light source that illuminates the display board and the original, and a light source that collects reflected light from the display board and the original are provided. shining lens,
A reading section consisting of a photoelectric conversion section that converts reflected light focused by a lens into an image signal, a board display section that displays on a display board according to the image signal output from the reading section, and an image output from the reading section. In an electronic whiteboard device comprising a recording section that records on a recording medium according to a signal,
The display board is composed of a pair of rolls that support the sheets of the display board, and rolls that move continuously up and down or left and right between the pair of rolls.

In order to achieve the above second objective, the display board is configured such that the product of the number of pages on the display board and the width of one page is constant.

In order to achieve the third object described above, the display board is constructed of a pair of rolls that support the sheet of the display board, and a take-up roll that winds up the sheet of the display board between the pair of rolls.

In order to achieve the fourth object described above, the display board is exposed on both the front and back sides of the electronic whiteboard device, and the display board is configured so that writing can be performed from both sides.

In order to achieve the fifth object mentioned above, the apparatus is constructed by providing an operation panel that is detachable from the main body of the apparatus and a receiving section that receives operation signals from the operation panel.
