Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image display device having a display section for displaying image data on a screen and a printing section for printing image information on a printing paper.

[0002]

2. Description of the Related Art Conventionally, in an image display device in which a recycle sheet which is a thermoreversible image storage medium is used, an image display body in which a recycle sheet is formed in an endless form is composed of a pair of heat rollers, a tension roller and a platen roller. It is wound between and. These rollers are in a relationship of being located at the vertices of a triangle, and the display body moves around them.

The platen roller is connected to a pulse motor so as to rotate intermittently. The display body is nipped and moved by a heating recording device connected to the platen roller. The heating recording apparatus has a plurality of thermal heads whose temperature can be controlled, and the thermal heads are selectively heated according to the image information to record the image information on the display body.

The heat roller is a heating device that uniformly heats the display body to make the surface of the display body uniform. The heat roller is a cylindrical roller, a rod-shaped heating element therein, and temperature detection for controlling the heating temperature. The display body is sandwiched and conveyed between a heat roller, which is composed of an element and a temperature control device, and which maintains a constant heating state, and a silicon roller facing the heat roller, and is in a uniform state.

With these configurations, when the display body is rotated while the heat roller is heated to a temperature t2 or higher at which the surface of the display body becomes cloudy, the display body passing through the heat roller has a uniform cloudiness. Become a state.

When the cloudy display reaches the position of the heating recording device, the thermal head of the heating recording device responds to the image information.
The display is selectively heated to a temperature of not less than t1 and less than t2. When the display body is heated to a predetermined temperature by the heating recording device, the display body is moved by the action of the platen roller,
Cool to room temperature. In the cooled display body, its heated portion becomes transparent, and image information is recorded as a transparent portion on the cloudy surface.

After that, the display body on which the image information was recorded was further fed, and when it reached the heat roller, it was uniformly heated again to become cloudy and the image information was erased.

On the other hand, when the image information recorded on the display body is printed out on the printing paper, the thermal paper is manually inserted from the thermal paper insertion opening separately provided in the apparatus, and the thermal paper is inserted into the thermal paper. Recording was performed by a recording head different from that of the above-mentioned heating recording apparatus, and then discharged outside the apparatus.

In such an image display device using a recycled sheet, in order to reduce the size of the entire device, a thermal paper insertion port must be provided near the display portion of the image display device. It was Therefore, a lid is sometimes provided for the sake of aesthetic appearance of the image display device and for preventing dust and dust from entering.

[0010]

However, in an image display device in which a lid is provided at the insertion port of the thermal paper, when the image information is printed on the thermal paper, the lid of the insertion port is removed and the thermal paper is used as a recording head.

To form. It is therefore an object of the present invention to provide an image display device that prevents dust and dirt from entering and does not impair the aesthetic appearance and that is easy to operate.

Further, a switching lever for operating the moving mechanism is provided, and when the insertion opening is opened, the moving mechanism is driven by the switching lever to move the sheet guide member and the third surface provided on the switching lever. Aims to form the same guide surface as the second surface provided on the paper guide member.

Further, the paper guide member is provided with a fourth surface opposed to the second surface, and when the insertion port is opened, printing is performed by the second surface and the fourth surface of the paper guide member. It is also intended that a paper guide path be formed.

Further, the recording head, which has recorded the image information on the recycling sheet, is moved to a position where the image information is recorded on the thermal paper inserted through the insertion port of the thermal paper, in conjunction with the moving mechanism. Another object is to provide a small-sized and inexpensive image display device in which one recording head is configured to record image information on both a recycled sheet and a thermal paper.
