Embodiment Construction

[0048] Hereinafter, an embodiment will be described with reference to the drawings. figure 1 It is a diagram showing the configuration of a part of the mechanism and the block configuration of main circuits of the printer according to the present embodiment. In addition, in this embodiment, a thermal printer is taken as an example for description. Such as figure 1 As shown, the printer 100 includes a thermal print head 1, a stepping motor 2, a conveying mechanism 3, a cutting unit 4, a motor driver 5, a drive control part 6, a printer control part 7, a memory 8, a bus 9 and a D / A (Digital / Analog: digital / analog) converter 10.

[0049] The thermal print head 1 is a type of print head, and prints an arbitrary image on the print medium 200 by discoloring the print medium 200 through heat generated by each of a plurality of heating elements. The thermal print head 1 can change the heating temperature of each of the plurality of heating elements individually and in multiple stage...

Abstract

The invention discloses a motor control device, a printer and a control method, which can reduce the risk of misalignment and simultaneously shorten the pre-synchronization period. The motor control device includes a motor driver and a motor control part. The motor driver supplies drive current to the stepper motor. The motor control unit starts supplying the drive current to the stepping motor in accordance with the start instruction, gradually increases the drive current to a predetermined current value in a predetermined period, and then drives the stepper motor in a predetermined pattern to generate a driving force. The motor driver is controlled in such a way that the current value of the current is changed.

Description

[0001] This application claims the priority of the Japanese application with the application date of July 25, 2017 and the application number JP2017-143545, and cites the content of the above application, and its disclosure content is incorporated herein by reference in its entirety. technical field [0002] Embodiments of the present invention relate to a motor control device, a printer and a control method. Background technique [0003] Conventionally, there is known a printer that prints a two-dimensional image while performing sub-scanning by moving at least one of the print medium and the print head by a moving mechanism using a print head that simultaneously prints a part of a plurality of rasters constituting an image. Also, the moving mechanism has a stepping motor as a drive source. [0004] The stop position of the stepping motor is not fixed in the non-energized state. Therefore, at the start of the stepping motor, a current of a predetermined current value is su...
