[38] As illustrated in FIGS. 1 to 6, the blackboard having a video display terminal according to embodiments of the present invention includes horizontal frames 110 installed to the upper and lower sides of the front wall of a classroom, vertical frames 120 provided to the lateral sides of the horizontal frames 110 to support and fix the horizontal frames 110, and a single or plural rail recesses 111 formed in the horizontal frames 110 in the longitudinal direction of the horizontal frames 110.

[39] Moreover, a bulletin board 140, to which a printed matter such as a time schedule for lectures, notices, and the like is attached, is provided to the other front sides of the horizontal frames 110.

[40] The bulletin board 140 is coupled in the rail recesses 111 of the horizontal frames

110 to slide along the rail recesses 111 or is coupled with the vertical frame 120 such that the other end of the bulletin board 140 is coupled with the vertical frame 120 by a rotation body 150 to pivot. In this case, the bulletin board 140 slides along the rail recesses 111 or pivots about the rotation body 150 to be spread so that the front wall of the classroom is exposed.

[41] Here, a wire may be provided to support the bulletin board 140 when the bulletin board 140 is pivoted and spread. In an ideal state, one end of the wire is fixed to the horizontal frames 110 and the other end of the wire is connected to the upper end of the bulletin board 140 to face the rotation body 150 so as to support the spread bulletin board 140.

[42] Furthermore, an auxiliary blackboard 160 may be provided to write thereon in the rear side of the spread bulletin board 140, or the bulletin board 140 may be provided only to one side or both sides of the horizontal frames 110.

[43] The bulletin board 140 may be provided to both inner lateral sides of the horizontal frames 110 and the vertical frames 120 which are installed to the front wall of the classroom.

[44] Additionally, a main blackboard 130 for writing is provided in the horizontal frames 110. Rollers 131 are provided to the upper and lower sides of the main blackboard 130 facing the rail recesses 111 so that the main blackboard 130 can slide along the rail recesses 111.

[45] In this case, the sliding main blackboard 130 enters inside the bulletin board 140 so that some of the front wall of the classroom can be exposed.

[46] The sliding main blackboard 130 may be divided into two parts about the vertical center line such that the two divided parts of the main blackboard 130 slide to enter inside the bulletin board 140 in both lateral directions along the rail recesses 111, and thus the central area of the front wall of the classroom is exposed.

[47] Furthermore, in the case where the bulletin boards 140 are installed to both the lateral sides of the wall, the front central wall is exposed and the bulletin boards 140 are concealed while the divided parts of the main blackboard 130 slide toward the both lateral sides. At that time, the main blackboards 130 can be still used to write on.

[48] Here, the main blackboard 130 and/or the auxiliary blackboard 160 may be a blackboard in dark green or dark blue, or a white board in which a marker pen is used for writing.

[49] On the exposed wall, in order to perform the audiovisual education using various media, a video display terminal 170 for displaying texts, symbols, figures, images, and sounds is provided.

[50] In addition, the video display terminal 170 may be provided in the rear side of the pivoting and spreading bulletin board 140.

[51] Here, a monitor, TV CRT, a liquid crystal display, a thin film liquid crystal display, a plasma display panel, a flexible display, and a head mount display may be used as the video display terminal 170.

[52] The operation of the blackboard having a video display terminal according to the present invention will be described as follows.

[53] Firstly, the lecture is carried out while writing on the main blackboards 130 when the lecture is carried out while writing on the blackboard without the audiovisual education.

[54] In addition, when the audiovisual education is carried out, the main blackboard 130 is slid toward the bulletin board 140 such that the other end of the main blackboard 130 is inserted into the rear side of the bulletin board 140 and the video display terminal 170 provided on the one side of the wall is exposed to the exterior.

[55] Like this, when the video display terminal 170 is exposed, texts, symbols, figures, images, and/or sounds are outputted so that the audiovisual education can be carried out. The complementary lecture for the displayed images is carried out while writing on a part of the main blackboard 130 which is not inserted into the rear side of the bulletin board 140.

[56] As described above, the video display terminal 170 is provided in the blackboard

100 of the classroom so that participants at the lecture can concentrate their eyes on the video display terminal 170 and the main blackboard 130 without the dead angle.

[57] Moreover, when writing on the main blackboard 130 is carried out for the complement of the image displayed on the video display terminal during the audiovisual education, the video display terminal 170 and the main blackboard 130 are in the same visual field so that the participants do not scatter their eyes but can concentrate their eyes on the image outputted from the video display terminal 170 and the main blackboard 130 on which the writing is carried out.

[58] Therefore, the video display terminal 170 for the audiovisual education and the main blackboard 130 on which the writing is carried out are located at the same place so that eyes can be oriented forward.

[59] Moreover, as illustrated in FIG. 3, when the main blackboards 130 slide toward the both lateral sides to expose the video display terminal 170, the two divided main blackboards 130 are slid toward the bulletin boards 140 such that parts of the divided main blackboards 130 are inserted into the rear sides of the bulletin boards 140 and the video display terminal 170 provided on the central wall is exposed. Thus, the audiovisual education can be carried out and parts of the divided main blackboards 130 are used to write on.

[60] As illustrated in FIG. 4, in a case where the bulletin board 140 installed to the other side of the blackboard pivots and the video display terminal 170 is exposed, the bulletin board 140 is usually used to attach a printed matter such as a time schedule for lectures, notices, and the like and, in order to carry out the audiovisual education, pivots about the rotation body 150 and is spread to expose the video display terminal 170.

[61] When the video display terminal 170 is exposed, the audiovisual education can be carried out and the writing is performed on the auxiliary blackboard 160 or the main blackboard 130 which are provided in the rear side of the bulletin board 140.

[62] Moreover, as illustrated in FIG. 5, in a case where the video display terminal 170 is installed on the rear surface of the bulletin board 140, the bulletin board 140 is usually used to attach a printed matter such as a time schedule for lectures, notices, and the like, and in order to carry out the audiovisual education, pivots about the rotation body 150 and is spread to expose the video display terminal 170. Thus, the participants can concentrate their eyes forward.

[63] Furthermore, as illustrated in FIG. 6, in a case where the bulletin boards 140 are provided on both the lateral side walls of the video display terminal 170, the divided main blackboards 130 are usually used to write thereon and the bulletin board 140 is usually used to attach a printed matter such as a time schedule for lectures, notices, and the like. In order to carry out the audiovisual education, the divided main blackboards 130 are slid toward both the lateral sides along the rail recesses 111 so that the video display terminal 170 is exposed and the bulletin boards 140 are concealed.

[64] At that time, since the main blackboards 130 are disposed in front of the bulletin boards 140, the main blackboards 130 can be used to write thereon as they are. When the bulletin boards 140 are concealed, the notices attached on the bulletin boards 140 are also concealed so that the participants can concentrate their eyes on the video display terminal 170 and the writing areas of the main blackboards 130.
