JPH02162099A - Electronic blackboard with eraser - Google Patents

Abstract

PURPOSE:To erase information written automatically by installing an eraser for erasing information, a drive section for pushing and detaching the eraser against and from a recording section and a switch for operating the drive section to an electronic blackboard. CONSTITUTION:A reading section 2 is slid in the direction of the arrow A when a transfer switch is operated regarding information written onto the surface of a belt- shaped recording section 1, and information written is reduced and a transfer paper 5 printed is discharged in a printer 6. When the information of the belt-shaped recording section 1 must be erased, a solenoid 8 is operated and a support lever 9 is turned when a switch 4 is worked, and an eraser 3 is pushed onto the belt-shaped recording section 1 by the working of a compression coil spring 10. The belt-shaped recording section 1 is rotated in the direction of the arrow B while being driven by a motor, into which the eraser 3 is incorporated, and revolved in the direction of the arrow C, and the information of the belt-shaped recording section 1 is erased on the surface of the eraser. When the erasing of information is confirmed by a sensor section 7, erasing operation is completed, the solenoid 8 stops its operation, and the eraser 3 is detached from the surface of the belt-shaped recording section 1 by the resiliency of the compression coil spring 10.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is capable of transferring information written on a blackboard onto recording paper.
The present invention also relates to an electronic blackboard with an eraser that can automatically erase information.

(Prior Art) Conventional electronic blackboards of this type are configured so that written information can be transferred onto recording paper without relying on human hands.However, in order to erase information, a person must use an eraser. He held it in his hand and operated it to wipe it away.

(Problem M to be Solved by the Invention) However, the conventional electronic blackboard described above has a problem in that written information can only be erased manually. The present invention solves the above problems and provides an electronic blackboard with an eraser that can automatically erase written information.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an eraser for erasing written information, a drive section for pressing the eraser against a blackboard, and a switch for operating the drive section. It is intended to provide

(Function) With the above configuration, the drive section is actuated by operating the switch and presses the eraser against the blackboard, so that written information can be automatically erased.

(Example) A first example of the present invention will be described with reference to FIGS. 1 and 2.

1 and 2 are a perspective view and a plan view showing a first embodiment of an electronic blackboard with an eraser according to the present invention.

In FIG. 1, an electronic blackboard with an eraser has a rotatable belt-shaped recording section 1 stretched between pulleys (not shown) provided on the left and right sides, and a recording section 1 that moves along the surface of the recording section 1 to write on it. a reading section 2 for reading information from the recording section 1, an eraser 3 for erasing information from the recording section 1 that has been read, and a switch 4 for operating a drive section (not shown) for the eraser 3, which will be described later.

It is comprised of a printer 6 that prints the above-mentioned information on the transfer paper 5, and a sensor section 7 that is placed on the back side of the above-mentioned reading section 2 and detects the presence or absence of information.

In FIG. 2, one drive section of one cylindrical eraser 3 includes a solenoid 8 connected to the above-mentioned switch 4, a support lever 9 that rotates when driven by the solenoid 8, and a support lever 9 that rotates when the above-mentioned solenoid 8 is activated. , a compression coil spring 10 that applies a counterclockwise rotational force to the support lever 9, and an electric motor (not shown) built in the cylindrical eraser 3 rotatably supported at the tip of the support lever 9. It consists of

The operation of the electronic blackboard with an eraser configured as described above will be explained.

When a transfer switch (not shown) is operated, the reading section 2 slides in the direction of the arrow to reduce the written information and print the information written on the surface of the belt-shaped recording section 1 by the printer 6. The transferred paper 5 is discharged. When you want to erase information on the belt-shaped recording section 1, operate the switch 4 and the solenoid 8 will be activated.

By rotating the support lever 9, the eraser 3 is pressed onto the belt-shaped recording section 1 by the action of the compression coil spring 10.

Subsequently, the belt-shaped recording section 1 rotates in the direction of arrow B, and at the same time, the eraser 3 is driven by a built-in electric motor (not shown) and rotates in the direction of arrow C, and the belt-shaped recording section 1 is rotated on its surface. Delete information. When the sensor section 7 confirms that the information has been erased, the erasing operation is completed, the solenoid 8 stops operating, and the eraser 3 separates from the surface of the belt-shaped recording section 1 due to the repulsive force of the compression coil spring 10.

3 and 4 are a perspective view and a plan view showing a second embodiment of the electronic whiteboard with an eraser according to the present invention.

The second embodiment shown in FIGS. 3 and 4 differs from the first embodiment shown in FIGS. 1 and 2 in that a fixed plate-shaped recording section 11 is used for storing information. And, as shown in FIG. 4, the reading section 2, the eraser 3, its driving section, and the sensor section 7 are housed in the carriage 12 that slides along the surface of the plate-shaped recording section 11. It is.

Since the rest remains the same, the same components are given the same reference numerals and their explanations will be omitted.

The operation of the electronic blackboard with eraser configured in this way is as follows.
The eraser 3 and sensor section 7 move back and forth along the surface of the plate-shaped recording section 11 together with the carriage 12 during erasing, and this is the same as the first embodiment except that the erasing is performed.

(Effects of the Invention) As explained above, according to the present invention, there is no need to manually erase information, so it is possible to prevent hands from getting dirty. Furthermore, since the erasing time can be used effectively, the efficiency of meetings, etc. can be improved.
