2. Description of the Related Art Conventionally, as shown in FIG. 1, an image recording card A capable of printing and erasing by heating is known.

That is, a transparent polyester film a has a recording layer b on the upper surface thereof, and a protective layer c is formed on the upper surface thereof. Thermoreversible recording is possible, and when heated to room temperature, the turbid and transparent states can be maintained semipermanently and stably.
Since the turbidity temperature is 90 to 100 ° C, printing can be performed with a normal thermal head. Since the clearing temperature is 65 to 90 ° C, the printed portion can be erased.

When the image recording card is used, a reading device for reading, a printing device such as a thermal head for printing, and a erasing device for erasing characters by heating are separate devices.

Further, as a character erasing device for the image recording card, a heat roll erasing device, a thermal head erasing device, and a sandwich heating erasing device using a single-sided heating element have been considered. FIG. 11 shows a heat roll erasing device. Reference numeral 1 denotes a heat roll having a heater inside, which is pressed against a drive roll 2 so as to be vertically movable. The printed image recording card 3 is sandwiched between the heat roll 1 and the driving roll 2, the driving roll 2 is rotated to move the image recording card 3, and the printing portion is heated to a predetermined temperature. Heat and erase.

FIG. 12 shows a thermal head erasing device.
Reference numeral 4 is a well-known thermal head, which is pressed against a drive roll 5 so as to be vertically movable. The printed image recording card 3 is sandwiched between the thermal head 4 and the driving roll 5, the driving roll 5 is rotated to move the image recording card 3, and the printing portion is heated to a predetermined temperature. Heat and erase.

FIG. 13 shows a clasp heating / erasing device using a single-sided heating element. A single-sided heating element 7 having a flat lower surface is arranged above the fixing member 6 having a flat upper surface so as to be vertically movable, and the single-sided heating element 7 is displaced upward to fix the image recording card 3 to the fixing member 6. Then, the one-sided heating element 7 is pressure-bonded onto the image recording card 3 and heated to a predetermined temperature in a stationary state to erase the character.

SUMMARY OF THE INVENTION In the above-mentioned prior art, when printing, reading, erasing, or changing / editing the image recording card, each image recording card must be changed. There was a problem that it was necessary to move between the devices, which was very troublesome and inefficient.

Further, in the heat roll erasing device, the image recording card erases characters while rubbing against the heat roller, so that the image recording card is erased.
The surface of the image is easily scratched, and since the image recording card and the heat roll are in line contact with each other, the erasing time becomes long, and the temperature peculiar to the image recording card is required for erasing the printing portion. As a result, uneven writing occurs due to uneven heating during line contact with a heat roll, and the moving speed of the image recording card during erasing is restricted, which complicates the device structure and makes repairs and inspections. There was a problem that it was not easy.

In the thermal head erasing device, the image recording card rubs the thermal head so that the surface of the image recording card is easily scratched and dust is likely to accumulate on the thermal head. There is a problem that the life is shortened and the erasing time is lengthened due to point and line contact between the thermal head and the image recording card.

Since the clinging heating device using a single-sided heating element heats only one side of the image recording card, heat is taken up by the fixing member, and it takes time for the image recording card to reach the erased temperature without the heat being accumulated. There was a problem that

The image recording card A is moved forward by being sandwiched between the driving roller 16 and the driven roller 19, the reading device 13 temporarily reads the data content, and transfers it to the host computer (not shown). It is stored in the storage device or transferred to another terminal device. After confirming the transfer, the image recording card A is used and erased by the erasing device 15, and is stored in the storing portion (not shown) for reuse without being returned.

[0020]

According to the present invention, an image recording card insertion port capable of printing and erasing by heating is formed on the front side of the housing,
A reading device, a writing device such as a thermal head, and a erasing device composed of a pair of heating bodies for sandwiching and heating the image recording card from both sides are arranged at regular intervals in the housing to convey the image recording card. Since a drive roll for driving, a follower roll and a drive source for forward and reverse rotation of the drive roll are provided, printing, reading, erasing and printing on the image recording card are performed. When changing / editing, the apparatus of the present invention can be efficiently processed without any trouble. Further, the use of the erasing device of the present invention has the following effects.

A. Since the image recording card printing portion is heated from both sides by the facing heating elements placed in the pre-erased temperature state, the characters are erased in a short time. b. At the time of erasing characters, the image recording card is in a stationary state, so scratches such as scratches are less likely to occur. c. At the time of erasing, the image recording card is uniformly pressed from both sides by the heating element, so that the dents and scratches that are likely to occur at the time of erasing are less likely to occur. d. Since the image recording card and the heating member are in surface contact with each other, it is possible to uniformly heat the entire surface of the printing portion, eliminate unevenness in erasure, and ensure reliable erasure. e. Since the known structure is simple, the entire device can be downsized.

In the case of the second embodiment, the plane accuracy of the upper heat medium and the lower heat medium is not required, which leads to cost reduction.
