Abstract: The improved package of thermal recording sheets comprises a container of a stack of thermal recording sheets and a humidity control agent that is secured to the container having an opening through which the thermal recording sheets can be taken out individually. The improved magazine comprises an enclosure for accommodating sheetings that have their sensitivity varied with humidity changes, a cover that is adapted to be opened or closed with respect to the enclosure and a mechanism for engaging the cover with the enclosure, wherein all areas of the cover that mate with the enclosure are furnished with a moisture resisting structure. Both the package and magazine ensure that a plurality of sheetings such as thermal recording films that are highly sensitive to moisture can be held at all times in a desired humidity environment in a moisture controlled state, especially in the interior of a thermal image recording apparatus. In addition, the thermal recording sheets can be easily supplied to the thermal image recording apparatus without touching them directly by hand and, hence, images of high quality can be recorded in a consistent manner.

Abstract: An electric driving device for openable members in which an openable member is opened and closed by rotation of driving shafts provided on right and left sides. The device includes a motor which rotates the driving shafts via a reduction mechanism, and switching relays which switch the rotational direction of the motor. Open and close command switches command the opening and closing of the openable member and a rotation synchronization sensor associated with the motor generates pulses synchronized with the rotation of the motor. A mechanical stopper limits the rotation of the driving shaft which is rotated via the reduction mechanism of the motor and a motor lock detecting means detects locking of the motor by detecting the pulse width generated by the rotation synchronization sensor. Also, an actuation stopping arrangement stops the actuation of an actuation device which supplies current to the motor if a signal is generated by the detection apparatus that detects locking of the motor.
