Abstract: A latent heat regenerating apparatus includes a regenerative tank wherein a latent heat regenerative material is housed. The material has a phase transition temperature and a supercooling-release temperature and is capable of maintaining a supercooled-state in a temperature range between the temperatures. A thermoelectric cooling element is located in the regenerative material so as to control supercooling of the material. The element has a heat radiating portion for radiating heat into the material and a heat absorbing portion for absorbing heat from the material, thereby cooling that portion of the material near the absorbing portion to a temperature lower than the supercooling-release temperature.

Abstract: A facsimile device includes an image pick-up means for picking up an image on an original moving relative to the image pick-up means, a transmitting means for appropriately processing the image signal from the image pick-up means into a modulated signal suitable for signal transmission, a coupling means for coupling the transmitting means with a transmitting system to provide a path for the modulated signal therebetween, and an original transfer means for transferring the original. The image pick-up means and the transmitting means are respectively provided with first and second cases so that the image pick-up means is slidable on an original such as a book. The second case may be placed on the first case. The coupling means is removably coupled with either of the transmitting means and the transmitting system. The original transfer means transfers the original between the first and second cases while the first case is placed on the second case.
