Abstract

PROBLEM TO BE SOLVED: To independently move an upper whiteboard surface and a lower whiteboard surface in the lateral direction each other, and at the same time, simultaneously move them together when required by hanging the whole bodies of the whiteboard surfaces as an endless sheet between parallel rollers which form pairs on the right and the left, and dividing the whiteboard surface into a plurality of parts in the vertical direction. SOLUTION: On both right and left end sides in a main body frame 1, two pairs of rollers are arranged, and between the arranged rollers, an upper whiteboard surface 81 and a lower whiteboard surface 82 are hung under an endless state. Also, respective upper and lower whiteboard surfaces 81 and 82 are placed under a state being exposed from an opening 3, and by a motor which is connected to either one of the spindle rollers, the upper and lower whiteboard surfaces are made independently movable in the lateral direction each other, and when required, they are simultaneously made movable together in the lateral direction. By this constitution, even when written information on the front side whiteboard surface needs to be frequently referred while a user is writing on the rear side whiteboard surface, the number of interruptions of the writing work on the rear side whiteboard surface can be reduced, and the writing on the rear side whiteboard surface can be smoothly performed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blackboard used in a conference room or the like, which is capable of so-called electronic copying.

[0002]

2. Description of the Related Art In the past, electronic blackboards are configured such that a blackboard surface as an endless sheet is simply suspended between a pair of left and right parallel rollers in a lateral direction. is there. Therefore, the usual usage of such an electronic blackboard is that if the currently written (front) blackboard surface is full of writing information, the (front) blackboard surface and the (backside) blackboard surface will be placed on the back and front respectively. To be located
The (front side) blackboard surface is moved leftward or rightward, and information is continuously written on the newly located (backside) blackboard surface. In a general electronic blackboard, the writing information on the blackboard surface can be copied on a recording sheet later by an image reading function such as a scanner as needed.

[0003]

On the other hand, in the case of an electronic blackboard, information is often written on the (backside) blackboard surface in relation to the information written on the (front side) blackboard surface. However, as a problem in such a case, it is necessary to frequently refer to the writing information on the (front side) blackboard surface while writing on the (back side) blackboard surface. Each time the reference is made, the writing operation on the (backside) blackboard surface is temporarily interrupted, and the (backside) blackboard surface needs to be temporarily positioned on the backside by moving in the left-right direction, which is cumbersome.

An object of the present invention is to provide a method for writing on a (backside) blackboard surface even when it is necessary to frequently refer to writing information on the (frontside) blackboard surface during writing on the (backside) blackboard surface. An object of the present invention is to provide a blackboard surface vertical split type electronic blackboard capable of performing writing on the (backside) blackboard surface with a reduced number of interruptions of the writing operation.

[0005]

SUMMARY OF THE INVENTION The object of the present invention is basically to divide the entire blackboard surface as an endless sheet vertically suspended between a pair of left and right parallel rollers so as to be movable in the left and right direction. This is achieved by the upper and lower blackboards being configured to be freely movable in the left and right directions independently of each other. This is achieved by being configured such that the blackboard surface can be freely moved in the left-right direction independently of each other, but can be simultaneously moved in the left-right direction simultaneously as needed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present development is shown in FIG.
This will be described with reference to FIG. First, an overall configuration of a blackboard surface vertical split type electronic blackboard according to the present invention will be described. FIG. 1 shows an overall schematic configuration of an example thereof. As shown in the figure, a main body frame 1 of the electronic blackboard is supported by a pair of stands 2, and an opening 3 is provided on a front surface of the main body frame 1. Further, an operation panel 4 is mounted on the main body frame 1 located below the opening 3, and a printer 5 for electronically copying information written on a blackboard surface is mounted below the main body frame 1. It has been done.

FIG. 2 is an exploded perspective view of the main part of the electronic blackboard. As shown in the figure, a pair of main shaft rollers 6 and two pairs of rollers 7 are disposed on both left and right sides in the main body frame 1, and between the two pairs of rollers 7, there is also an endless upper blackboard surface. 81 and lower blackboard surface 8
2 is suspended. Each of the upper blackboard surface 81 and the lower blackboard surface 82 is exposed from the opening 3 and is mutually independent by a motor (not shown) connected to one of the main shaft rollers 6 as described later. The roller 7 can be freely moved in the left-right direction at the same time as it is movable in the left-right direction.
It is suspended in between. Information can be written on each of the upper blackboard surface 81 and the lower blackboard surface 82 that are actually exposed from the opening 3, but the information written on these blackboard surfaces 81 and 82 will be used later as necessary. The image data is electrically read as image information by a scanner 9 attached to the main body frame 1 as needed, and can be copied from a printer 5 onto recording paper.

Here, the operation panel 4 will be described. As shown in FIG. 3, the operation panel 4 is provided with various operation keys 10 to 15 including a power on / off key. . The functions of these various operation keys (excluding the power on / off key) are as follows.

Lower blackboard copy start key 10: A key for starting a copying operation for copying the writing information on lower blackboard 82 onto recording paper Upper blackboard copy start key 12: Writing on upper blackboard 81 A key for starting a copying operation for copying information onto recording paper Upper and lower blackboard surface copy start key 11: for starting a copying operation for copying writing information on upper and lower blackboard surfaces 81 and 82 onto recording paper. Key Upper blackboard surface moving key 13: Upper blackboard surface 8 in an exposed state
Key for moving 1 in the left or right direction Lower blackboard surface moving key 14: Lower blackboard surface 8 in an exposed state
Key for moving 2 in the leftward or rightward direction Upper and lower blackboard surface moving keys 15: keys for moving the exposed upper and lower blackboard surfaces 81 and 82 in the leftward or rightward direction As can be seen from the above description of the function, the upper and lower blackboard copy start key 11 and the upper and lower blackboard move key 15 are provided on the conventional electronic blackboard. Others have been founded for the first time by the present invention.

A brief description will be given of a method of using the electronic blackboard as described above. A writer writes characters and figures on the exposed upper and lower blackboard surfaces 81 and 82 as information. But soon,
When the writing operation is continued even after the lower blackboard surfaces 81 and 82 are filled with the writing information, the upper blackboard moving key 13 or the lower blackboard moving key 14 is pressed. It has become. As a result, as shown in FIG. 4, the projections (claws or the like) 16 protrude from the upper main surface roller or the lower main surface surface roller, and the motor is driven to rotate. . Eventually, the protrusion 16 will be caught on the pawl plate 17 disposed in the upper chalkboard roller or the lower chalkboard roller. As a result of the rollers being rotated in conjunction with the upper blackboard main shaft roller or the lower blackboard main shaft roller, the upper blackboard surface 81 or the lower blackboard surface 82 can be moved in a desired direction. However, when the upper and lower blackboard surface moving key 15 is pressed down in the same manner as the conventional electronic blackboard, the upper blackboard surface 81 and the lower blackboard surface 8 are pressed.
2 can be moved in conjunction with a desired direction.

[0011]

As described above, according to the first and second aspects, it is necessary to frequently refer to the writing information on the (front side) blackboard surface while writing on the (back side) blackboard surface. Even in this case, writing on the (backside) blackboard surface can be performed with a reduced number of interruptions of the writing operation on the (backside) blackboard surface.
