DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings. FIG. 1 shows an electronic blackboard device 1 according to the writing device of the present invention. In the electronic blackboard device 1, a writing surface 3A for writing information appears at the front opening W of the housing 2 supported by the stand 20A, similarly to the conventional one. Information written on the surface 3A can be printed.

That is, in the electronic whiteboard apparatus 1, a sending section 3 for feeding another writing surface 3A into an opening W and a reading apparatus provided with a photoelectric conversion element, a lens, and the like (not shown), as in the conventional one. Unit, a printing unit 5 for printing the read information read by the reading unit, and an operation unit 6 provided with a switch for operating the printing unit 5 and the like. Particularly, in this example, the cleaning unit 4 is further provided. It has.

As shown in FIG. 2, the housing 2 includes a back member 20 attached to a stand 20A, a left outer frame 21, a right outer frame 22, and corner frames 23, 24, 25, 26.
And an upper outer frame 27 and a lower outer frame 28. Of these, slide grooves 21A and 22A are engraved on the inner wall surfaces of the left outer frame 21 and the right outer frame 22, respectively.

A drive roller 31 (see FIG. 1), which constitutes a part of the sending section 3, is attached to the left end of the back member 20, and the inside of the corner frames 23, 25 and the inside of the left outer frame 21 are attached. The driving roller 31 fits into the housing. Further, a sending part 3 is provided on the right end side of the back member 20.
A driven roller 32 (see FIG. 1) which constitutes a part of the outer frame 2 is mounted inside the corner frames 24 and 26 and the right outer frame 2.
The driven roller 32 is accommodated in the inside 2.

In FIG. 1, a sheet member 33 extends between a driving roller 31 and a driven roller 32. Of the sheet member 33, a portion of the exposed surface that is extended to the housing opening W surrounded by the upper, lower, left, and right outer frames and the corner frame is a writing surface 3A. This sheet member 33
Are moved in the horizontal direction by the driving force of a motor (not shown) provided on the driving roller 31 to feed out the next writing surface. The information written on the writing surface 3A in this example is erased by the erasing tool E shown in FIG. Note that a blackboard eraser having a cloth wiping portion such as felt is used for the erasing tool E of this example.

When the information written on the writing surface 3A with ink or the like is wiped off with the erasing tool E using a writing tool such as a felt pen or the like, the cleaning means 4 adheres to the writing surface 3A. It removes body-like wipes and the like.

As shown in FIG. 3, the cleaning means 4 of this embodiment includes a blade 41 made of an elastic member such as rubber, and a support member 42 having a substantially U-shape and fixing the blade 41 thereto. A slide shaft 42A projects from both sides of the support member 42. As shown in FIG. 4, the slide shaft 42A is engaged with slide grooves 21A and 22A of the left outer frame 21 and the right outer frame 22, respectively. ing. Here, the cleaning unit in this example is configured to move in the vertical direction, but may be configured to move in the horizontal direction.

In this example, the slide shafts 21A, 21A
Although a cross section having a perfect circular shape is used for 2A, a configuration having a contact / separation mechanism as shown in FIG. 5, for example, may be used. In other words, this contact / separation mechanism separates the blade from the writing surface 3A when the cleaning means 4 is not used, so that no extra load is applied to the sheet member 33.

In the contact / separation mechanism of this embodiment, the cleaning means 4 is rotated by 90 degrees only when the blade 41 and the support member 42 have descended to the lowermost position, and the blade 41 is vertically suspended from the writing surface 3A. In order to separate the blade 41, a slide shaft 42A having a square cross section and having only one surface rounded is used. On the other hand, the left outer frame 21 and the right outer frame 22 (only the left outer frame is shown in FIG. 5) are provided at the lower ends of the slide grooves 21A and 22A with rotating holes 21B and 22B for rotating the slide shaft 42A by 90 degrees. Is drilled. This rotation hole may be formed at the uppermost part of the slide groove.

Next, the operation of this example will be described. According to this example, when printing the information written on the writing surface 3A, the print switch of the operation unit 6 is turned on as in the conventional case. Then, the information written on the writing surface 3 </ b> A is optically read by the photoelectric conversion element of the reading unit, and the read information can be printed by the printing unit 5.

On the other hand, erasing by wiping with the erasing tool E,
If a large amount of fine ink wiping residue remains on the writing surface 3A and becomes dirty, as shown in FIGS. 6 and 7, the hanging support member 42 is rotated by 90 degrees by hand. And tilt it horizontally to change its orientation so that it is perpendicular to the writing surface 3A. Thereby, the blade 41 comes into contact with the writing surface 3A.

Next, the blade 41 is slid upward from the bottom so as to be pushed up along the slide grooves 21A and 22A while grasping the support member 42 by hand. Thereby, the tip of the blade 41 moves while contacting the writing surface 3A, and fine wipes remaining on the writing surface 3A can be removed. Similarly, when the blade 41 is slid from top to bottom, fine wipes remaining on the writing surface 3A can be removed.

After such a cleaning operation, the cleaning means 4
Is the slide groove 2 so that it does not get in the way when writing information.
What is necessary is just to slide to the lowest part of 1A, 22A, and to arrange there. In the case of the one provided with the contact / separation mechanism, the support member 4 extends to the bottom of the slide grooves 21A and 22A.
5, when the supporting member 42 is rotated by 90 degrees by hand to separate the blade 41 from the writing surface 3A while the blade 41 is hung down, as shown in FIG. When sending, it is possible to avoid an unnecessary load from acting on the writing surface 3A.

The cleaning operation by the cleaning means 4 does not need to be performed every time after the erasing by the erasing tool E.
This operation may be performed when the writing surface 3A becomes very dirty.

[0028]

As described above, according to the first aspect of the present invention, after the information written on the writing surface is erased by the erasing tool, the information remains on the entire writing surface. Cleaning means for removing the ink scraps of the writing implement while moving along the writing surface, and further cleaning the writing surface with the cleaning means after erasure of the information. Even when the information is written and the written information is erased, the writing surface can be kept in a clear state without being stained, and the inconvenience that the writing surface is hardly stained can be prevented.

Therefore, in the case of an electronic blackboard capable of printing information described on a writing surface as needed, the dirt on the writing surface becomes severe as the erasing operation is repeated many times, and the writing surface is finely wiped. It is possible to prevent a trouble that countless residues remain, and when information is recorded on the recording paper, the stain is recorded on the recording paper.

Further, according to the second aspect of the present invention,
The cleaning means includes a support member and a blade provided on the support member, and the cleaning means is provided on a slide formed on both left and right outer sides and upper and lower outer frames constituting a part of the housing of the writing device main body. Since it can be realized with a simple configuration in which the support member is manually moved along the groove, it is convenient to reduce the size and cost of the device.

Further, according to the third aspect of the present invention,
The cleaning means includes a contact / separation mechanism for separating the blade from the writing surface, and in a device having a transport mechanism for transporting the writing surface, when the writing surface is transported, the blade is moved from the writing surface. Since the load is temporarily separated so that no extra load is applied, the motor for driving the writing surface does not require a large torque, and the motor can be downsized. Can be realized.
