Description

  Embodiments described herein relate generally to an electronic blackboard.

  A so-called electronic blackboard that reads an image written with a marker pen on a whiteboard and forms an image with a printer has a model that supports color printing and can store the image read in a portable storage device such as a USB memory. is there.

  Such a model can use many functions, but requires many buttons on the control panel. For example, in addition to a power button, the electronic blackboard has a color / monochrome print switching button, a print instruction button for a printer, a save instruction button for a USB memory, and the like.

  As described above, installing many buttons increases costs and enlarges the size of the control panel. The user does not know which button to press and the operability is poor.

  Hereinafter, an embodiment of an electronic blackboard will be described in detail with reference to the drawings.

  The electronic blackboard of the present embodiment includes a writing unit that carries an image, a light emitting unit that emits light to the writing unit, a reading unit that reads an image from the writing unit, and an image processing unit that generates print data from the read image. A printer interface connected to the image forming apparatus, a button for instructing printing or storing an image in the portable storage device, a mounting port of the portable storage device, and the portable storage device mounted in the mounting port In this case, the image read by pressing the button is stored in color in the portable storage device, and when the portable storage device is not attached to the mounting port, the image read by pressing the button is monochrome. Image processing control means for forming an image with the image forming apparatus.

  FIG. 1 is an external perspective view of the electronic blackboard 1 of the present embodiment. As shown in FIG. 1, an electronic blackboard 1 includes a writing unit 12 including a writing curtain formed of a white board or a flexible material, and a control panel that supports the writing unit 12 and includes an input / output unit. 13 and an image forming apparatus such as a printer 14.

  Hereinafter, a case where the writing unit 12 is a curtain will be described. The writing unit 12 forms an endless band, a part of the writing unit 12 is exposed in the direction of the writer, and the remaining part circulates inside the main body unit 11.

  The main body 11 further includes a control unit 301, a driving unit 310 that circulates the writing unit 12, a fluorescent lamp 308 that is a light emitting unit that irradiates the writing unit 12, and a reading unit that reads an image from the writing unit 12. A charge coupled device (CCD) 306, an image processing unit 305 that generates print data from the read image, and a printer interface (hereinafter referred to as an I / F) 311 that is connected to the printer 14.

  FIG. 2 is a diagram illustrating an example of the control panel 13. As shown in FIG. 2, the control panel 13 includes a display unit 13A for outputting characters and images, a copy number button 13B for inputting the number of copies, and a feed button for driving the drive unit 310 to circulate the writing unit 12. 13C, a copy button 13D for instructing to print or save an image in the portable storage device, and a USB (Universal Serial Bus) port 15 that is a mounting port of the portable storage device.

  FIG. 3 is a block diagram showing a configuration of the electronic blackboard 1. As illustrated in FIG. 3, the electronic blackboard 1 includes a control unit 301 including a CPU (Central Processing Unit) 301 </ b> A that is an arithmetic device, a ROM (Read Only memory) 302, a RAM (Random Access Memory) 303, and the like. USB host controller 304 that communicates with USB memory 320, image processing unit 305, CCD 306, fluorescent lamp lighting circuit 307, fluorescent lamp 308 including lens 313, control panel 13, drive unit 310, and printer 14 and a printer I / F 311 connected to the printer 14.

  When the copy button 13D of the control panel 13 is pressed, the control unit 301 turns on the light emitting unit, drives the drive unit 310 to rotate the writing unit 12, and the written writing unit 12 sequentially passes through the reading unit. To do.

  The fluorescent lamp 308 is turned on or off by a fluorescent lamp lighting circuit 307 controlled by the control unit 301.

  The light from the light emitting unit is applied to the writing unit 12, and the reflected light is collected through the lens 313. The condensed reflected light is incident on the CCD 306 serving as a reading unit.

  The CCD 306 photoelectrically converts incident light and outputs the obtained image signal to the image processing unit 305.

  The image processing unit 305 generates necessary print data for printing by the printer 14 after performing necessary processing on the input image data. The electronic blackboard 1 temporarily stores this print data in the RAM 303.

  The print data is transmitted to the printer 14 via the printer I / F, and printing is started.

  The USB port 15 is installed in the main body unit 11 and is connected to a USB host controller 304 that is connected to the control unit 301.

  The USB host controller 304 determines whether the USB memory 320 is attached. The control unit 301 periodically inquires of the USB host controller 304 whether or not the USB memory 320 is attached.

  In this embodiment, when it is determined that the portable storage device is attached to the attachment port, the electronic blackboard 1 stores the image read by pressing the copy button 13D in color in the portable storage device.

  When the electronic blackboard 1 determines that the portable storage device is not attached to the attachment port, the electronic blackboard 1 forms an image read by pressing the copy button 13D by the printer 14 in monochrome.

  FIG. 4 is a flowchart showing the operation of the electronic blackboard 1. As shown in FIG. 4, in step 401, the electronic blackboard 1 determines whether the copy button 13D has been pressed. If the electronic blackboard 1 determines that the copy button 13D is pressed, the electronic blackboard 1 proceeds to step 402. If not determined to be pressed, the electronic blackboard 1 returns to step 401.

  In step 402, the electronic blackboard 1 determines whether the USB memory 320 has been detected. If the electronic blackboard 1 determines that the USB memory 320 has been detected, the process proceeds to step 403, and if not, the process proceeds to step 404.

  In step 403, the electronic blackboard 1 forms an image with the printer 14 in monochrome, and the process returns to step 401.

  In step 404, the electronic blackboard 1 stores the print data or image data in color in the USB memory 320.

  Here, the print data may be a PDF or a PostScript file such as LPD. Further, the image data may be compressed data such as JPEG, GIF, and TIFF, for example.

  As described above, the electronic blackboard 1 of the present embodiment includes the writing unit 12 that carries an image, the light emitting unit that irradiates the writing unit 12 with light, the reading unit that reads an image from the writing unit 12, and the read image. An image processing unit 305 for generating print data from the printer, a printer interface 311 connected to the printer 14, a copy button 13D for instructing printing or storing an image in the portable storage device, and a port for mounting the portable storage device If it is determined that the portable storage device is attached to the attachment port, the image read by pressing the copy button 13D is stored in the portable storage device in color, and the portable storage device is attached to the attachment port. The image processing control means for forming an image read in monochrome by the printer 14 when the copy button is pressed; Provided.

  Therefore, there is an effect that an image can be stored in the portable storage device using fewer buttons.
