The present invention also relates to a information transmission display device having a new structure in which the information can be conveniently written.

In general, there is a method of notifying the absence or reservation, such as a note on a simple memo sheet or a method of preparing a situational information board prepared in advance.

For example, if a clerk such as a store or a ticket agent such as a ticket office or a bank clerk such as a bank is away for a while, a signboard for notification of the absence is provided at the door or the corresponding window so that the customer can be notified of the absence. will be.

In addition, restaurants, various restaurants, and the like have a signboard for notifying reservation details in order to display reserved seats for seats at the tables.

However, since the above-described conventional guide plate is made in advance for each situation, there is a problem that the one used in one place could not be used in another place.

For example, the information board used in the store could not be used for displaying reserved seats such as restaurants because the text indicating the absence was printed in advance, and the information board for displaying reserved seats used in the restaurant was absent at the store. It could not be used as a signboard to notify the seal.

In addition, the above-described conventional guide plate merely serves as a guide according to the situation, there is a problem that could not be used for other purposes, such as decorative.
