In a piezoelectric vibration type force sensor according to the present invention, vibration is restricted by a friction force between a piezoelectric body and a restricting member, and hence a range of sensing forces can be expanded compared with a case in which the vibration is restricted directly from a direction that is the same as an vibration direction. A conventional structure, in which a lead wire is soldered directly for electrically connecting the piezoelectric body to an external control circuit, causes a restriction of the vibration due to a solder attached to the piezoelectric body, resulting in narrowing the sensing range. Using the piezoelectric vibration type force sensor, the range of sensing forces can be expanded by making a state in which conducting portions of the piezoelectric body and the restricting member are not fixed but contact with each other for keeping electric conductivity.

A voltage supplied to each printing element can be stabilized even when a number of concurrently driven printing elements varies. A printhead with a plurality of printing elements includes a driving circuit for applying a predetermined voltage to each printing element according to a pulse signal defining a drive of a printing element inputted to the printhead. More specifically, the driving circuit is provided with a set voltage generation section for generating the predetermined voltage according to a setting signal inputted to the printhead. The section receives as the setting signal information on the number of concurrently driven printing elements, and the predetermined voltage applied to each printing element is set so as to have a constant value even when the number of concurrently driven printing elements varies.

A power supply device which converts a voltage by a switching method is connected to a load. Whether a current supplied from the power supply device to the load falls within a proper range is determined. At this time, while preventing an increase in cost in current detection and reducing Joule loss caused by an unwanted resistance component, it is determined that the current falls within the proper range. In order to determine a current supplied from a DC/DC converter to the load, a current determination unit ( ) is arranged. The current determination unit ( ) compares, with a preset voltage, a voltage obtained by DC-detecting a gate driving pulse signal used to turn on/off a switching MOS transistor ( ), thereby determining whether the current flowing from the DC/DC converter to the load exceeds a predetermined current (proper range). In current detection, Joule loss by an unwanted resistance component can be reduced.

In order to realize stable image printing, this invention provides an image printing apparatus capable of supplying a stable voltage to a printhead, and maintaining a compact shape. For this purpose, in the image printing apparatus in which a carriage which supports a printhead is scanned on a printing medium to print an image, a power converter which converts power to be supplied to the printhead is mounted on the first print circuit board of the carriage so as to supply a predetermined voltage to the printhead. The printhead and a power smoothing unit which smoothes the voltage converted by the power converter in accordance with the load of the printhead are mounted on the second print circuit board. The first and second print circuit boards are separately arranged at a proper gap in the image printing apparatus, which prevents an increase in the size of the image printing apparatus.
