Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting display device in which a plurality of light emitting display elements are arranged so as to represent fixed information such as specific characters, and the fixed information is displayed by light emission. The present invention relates to a device suitable for displaying a specific business display such as "Preparing".

[0002]

2. Description of the Related Art In general, a sign panel having a sign "in business" on the front and "preparing" or "closed" on the back is well known. However, since such conventional display panel only displays fixed information on the plate by silk printing, etc., it often goes unnoticed unless the customer comes close to the store, and it is not valuable especially for stores operating at night. It was a thing.

Therefore, it is conceivable to use a light emitting display element such as an LED to display the above fixed information by light emission to improve the visibility. However, it is necessary to display at least two types of information such as "open" and "preparing" and "open" and "closed day". It is necessary to use a matrix display that is arranged in a matrix and selectively turns on / off each light emitting element. However, the use of the matrix display requires a very large number of light emitting elements, and it is necessary to control lighting of each element individually, which causes a problem that the configuration is complicated and expensive. In the matrix display, characters must be expressed in a limited matrix such as 16 × 16 dots, and information including a character with a relatively large number of strokes, such as “in business” or “in preparation”, can be displayed with good display quality. It was difficult to display.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention addresses the above-mentioned problems and improves the visibility by displaying information such as "business hours" in a light emitting manner, and the light emitting display uses a matrix display. Instead of light emitting elements arranged in the shape of letters, it is possible to display with relatively low cost and good display quality, and information that cannot be displayed by light emission can be switched and displayed with the same ease as a conventional sign panel. The purpose is to provide a device.

[0005]

In order to achieve the above-mentioned object, the present invention provides a light emitting display device in which light emitting display elements are arranged in the shape of a character to display specific fixed information by light emission. The parts located above and below or on the left and right of the display surface of the device main body for fixing the arrayed display substrates are bulged forward from the display surface, and the locking grooves are respectively provided at the portions facing each other across the display surface of the bulged portion. Is formed so that a sign plate on which information other than the fixed information is displayed and which is large enough to cover the display surface can be locked.

It is desirable that a plate holding portion for holding the sign plate when it is not locked in the locking groove is formed behind the display surface in the apparatus body.

Further, a means for detecting whether or not the plate is locked may be provided, and the light emitting display may be turned on / off according to a signal from the detecting means.

In addition, in order to achieve the above-mentioned object, in a light emitting display device in which light emitting display elements are arranged in the shape of characters to display specific fixed information by light emission, the display substrate on which the light emitting elements are arranged is fixed. A flexible cover such as a screen that displays information other than the fixed information may be housed in the main body of the device, and the flexible cover may be pulled out to cover the display surface as necessary. it can.

In this case, a means for detecting whether or not the flexible cover is pulled out is provided, and the light emitting display may be turned on / off according to a signal from the detecting means.
