Reversible thermosensitive recording medium and method for producing the same

A heating device capable of evenly heating a thermal recording medium without increasing the cost of the device is disclosed. The heating device evenly heats the recording surface of a thermally-reversible recording card by conducting the heat energy transferred from a heat generating member by way of a heating member, made of aluminum having high heat conductivity and high heat capacity characteristics. By this feature, it becomes possible to accurately erase the information recorded on the recording card and to use an inexpensive heat generating member as the heat generating member.

Information recording and erasing apparatus

To provide a reversible thermosensitive recording medium comprising a support, a thermosensitive recording layer formed on the support, and a protective layer formed on the thermosensitive recording layer, wherein the thermosensitive recording layer contains an electron donative coloring compound and an electron acceptive compound, and the color tone reversibly changes depending on the temperature, and the protective layer contains a polymer of a composition containing two kinds of acrylate compounds selected from an acrylate compound having a pentaerythritol group and an acrylate compound having a dipentaerythritol group.

Reversible thermosensitive recording medium, as well as reversible thermosensitive recording label, reversible thermosensitive recording member, image processing apparatus and image processing method

An information recording apparatus enables information to be recorded in a thermosensitive recording medium accurately while preventing the development of skew. When a rewritable medium is conveyed to a recording unit, the rotation of the rewritable medium and its position with reference to an axis are adjusted. Specifically, the rewritable medium is held between guide pins to such an extent as not to warp the rewritable medium while the medium is sandwiched between a clamper and a conveyance tray, until the rewritable medium reaches the recording unit. Thus, the rewritable medium is delivered to the recording unit with an adjusted posture, allowing the recording unit to record information in the rewritable medium without the development of skew in the rewritable medium.

Information recording apparatus

A heating unit is disclosed that heats a heat-sensitive medium. The heating unit includes a heat generating body that converts electric energy into heat energy; a fixed member to which the heat generating body is fixed; and a holding member that directly holds the fixed member while contacting at least a part of the fixed member.
