Abstract

PURPOSE:To contrive reductions is power consumption and noise, by using gravity as a drive source for moving a carrier with a printing head mounted thereon in at least one direction. CONSTITUTION:A platen 1 is disposed vertically, and a carrier 2 with a printing head 3 mounted thereon is guided in the vertical direction by a front guide shaft 4 and a rear guide shaft 5 which are also disposed vertically. In moving the carrier 3 upward, a driving force is transmitted from a motor 7 to the carrier 3 through a wire rope 6, and printing is conducted. When the carrier 3 reaches the upper end and printing is completed, the motor 7 is deenergized, whereby the carrier 2 naturally falls under its own weight to return to an initial position.

Description

TECHNICAL FIELD The present invention relates to a printer device, and more particularly to a method for driving a carrier in a serial printer that prints characters serially.

Prior Art Conventionally, this type of serial printer has used a drive source such as a motor in both directions to drive the carrier.

The conventional serial printers mentioned above require continuous drive when moving the carrier in both directions, so for example, the most common motor drive requires high power most of the time during the printer's printing operation. , and there were problems such as continuous generation of driving noise.

OBJECTS OF THE INVENTION An object of the present invention is to provide a printer device that reduces power consumption and noise.

The printer device according to the present invention sets the carrier in the vertical direction, so that when the carrier is moving from the top to the bottom, a natural fall due to m force is used without using a particular drive source. This is the configuration.

Example Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a schematic diagram of an embodiment of the present invention. According to this embodiment, the platen 1 is arranged vertically, and the carrier 2 on which the print head 3 is mounted is guided in the vertical direction by the front guide shaft 4 and the rear guide shaft 5, which are also arranged vertically. . When the carrier 3 is moved from the bottom to the top, the drive from the motor 7 is transmitted by the wire row 76, and printing is performed at this time. When the carrier 3 reaches the upper end and printing is completed, the motor 7
By cutting off the current, the carrier 2 naturally falls due to its own weight and returns to its original position.

Note that although this embodiment shows an impact printer, it is clear that the invention can be applied to non-impact printers as well. Also, regarding the printing direction, contrary to the above embodiment, printing is performed when it falls naturally downward,
Of course, it is also possible to use a method in which printing is not performed when the carrier moves in the opposite direction, that is, upward, or a method in which printing is performed in both directions.

1 Hole Standing Bean j As explained above, according to the present invention, when the carrier of a serial printer is moved, it is not only driven in both directions (but when the carrier is moved from one side, that is, from the top to the bottom, it is driven by natural fall due to gravity). By utilizing this, there is an energy saving effect of keeping power consumption low and a noise reduction effect of shortening the generation time of drive noise of a carrier drive source such as a motor.
