Abstract: A sheet supply apparatus according to the present invention has a pawl separator for separating sheets one by one by regulating the tip ends and upper surfaces of tip end portions of the sheets, which pawl separator can be retarded from a sheet regulating position when it is urged by the sheet with a predetermined force. With this arrangement, sheets having small resiliency such as plain sheets are separated one by one by successively riding over the pawl separator, and sheets having great resiliency such as post cards and envelopes urge the pawl separator to a retracted position to pass through the pawl separator and are separated one by one by of another separation.

Abstract: An ink jet recording apparatus and method for preventing condensation from forming in a recording area having heaters for heating a recording head and a recording medium, a humidity detector for detecting the humidity in the recording area and a controller for controlling the temperature of the heaters in response to the humidity detected by the humidity detector. The controller decreases the temperature difference between the recording head and the recording medium by adjusting the heaters in order to lower the humidity in the recording area when it is higher than a predetermined value. If the humidity in the recording area is not controlled the quality of the recording will be impaired.

Abstract: The thermal printer pertinent to the present invention is of the type in which a heat sensitive paper having a coating of heat sensitive material on the upper side and a coating of heat fusible ink on the backside is used. A thermal head is brought into contact with the upper side surface under pressure to transfer the ink coated on the backside of the heat sensitive paper onto a common paper. According to the invention, a feed source of the heat sensitive paper and a feed source of the common paper are provided separately at different positions.

Abstract: A recording head having actuators driven by voltage supplied from a drive circuit constitutes a part of paths of a compensating circuit for compensating the drive voltage from the drive circuit. The paths are selectively cut off to compensate the drive voltage supplied to the actuators.

Abstract: A pulse motor is improved in its stability at the time of low revolution while maintaining the possibility of high revolution. Between the terminals of pulse motor windings there are parallel-connected current control means. The braking effect of said current control means is controlled depending upon the revolution of the pulse motor so as to stabilize the revolution at a low speed. It assures also a high speed revolution when desired. This arrangement of the invention enables to provide a pulse motor which is small in size and low in cost. When the present invention is embodied in a driving system for a carriage of printing head in a printer, all the performances required therefor can be attained.

Abstract: A thermal head driving device is provided with a safety circuit for preventing the heating resistors of a thermal head from being burnt or reduced in life by an abnormal printing pulse signal being applied to the heating resistors.
