Apparatus for notifying meeting schedule and System for reserving conference room}

The present invention relates to a conference schedule posting device and a conference room reservation system.

In general, there are department offices and laboratories for each business unit in the company building, as well as information offices for providing external guest guidance and supplementary services, and multiple meeting rooms for business partners or departmental team meetings. In general, the number of conference rooms is very small compared to many departments. Accordingly, most companies now have a conference room reservation system that allows departments or employees who want to use the conference room to request a reservation for the conference room through the information office.

By the way, the conference room is normally closed so that the inside of the conference room cannot be seen from the outside, so it was not possible to know who is currently using the conference room and whether the conference is actually held immediately outside the conference room. Accordingly, the conference room booker may finish the meeting within a shorter time than the scheduled time. In this case, there is a problem in that the other conference room reservation users cannot use the conference room immediately and are not efficient in terms of using the conference room. In addition, managers were not able to see if employees were actually working hard in the conference room.

On the other hand, sometimes the conference room reservation person does not use the conference room for some reason even if the conference room reservation is reserved. At this time, the existing conference room reservation system does not know whether to cancel the use of the conference room reservation room does not inform this, there was a problem that can not accurately manage the conference room usage information. In addition, the existing conference room reservation has been inconvenient to notify the meeting room reservation system administrator that the meeting room reservation has been canceled if the meeting is postponed or canceled.
