US 10,946,644 B2 · Printer device and method for generating appropriate conveyance force

Abstract

A temperature acquisition section (acquisition module) acquires a temperature of an environment in which a printer device is used. A printing condition acquisition section (acquisition module) acquires information relating to printing conditions of the printer device. A conveyance load estimation section (estimation module) estimates a conveyance load when a stepping motor (motor) provided in the printer device conveys a printing paper (print medium) based on the information acquired by the temperature acquisition section and the printing condition acquisition section. A current value setting section (setting module) sets a current value to be applied to the stepping motor based on the conveyance load estimated by the conveyance load estimation section. A motor control section (control module) controls the stepping motor by applying the current value set by the current value setting section to the stepping motor.

Dependent claims

A printer device, comprising:

an acquisition module configured to acquire a temperature of an environment in which the printer device is used and information relating to printing conditions of the printer device, wherein the printing conditions comprise fixed information representing conditions that do not change during printing and variable information representing conditions that change during printing;
an estimation module configured to estimate a conveyance load when a motor provided in the printer device conveys a print medium based on the information acquired by the acquisition module;
a setting module configured to set a current value to be applied to the motor based on the conveyance load of the print medium estimated by the estimation module;
and
a control module configured to control the motor by applying the current value set by the setting module to the motor,
wherein the acquisition module, at a start of printing, acquires the temperature of the environment and the printing conditions, and
wherein the acquisition module, during the printing, acquires the temperature of the environment and the variable information.

4 more elements

A method for generating an appropriate conveyance force by a printer device, comprising:

acquiring a temperature of an environment in which the printer device is used and information relating to printing conditions of the printer device, wherein the printing conditions comprise fixed information representing conditions that do not change during printing and variable information representing conditions that change during printing;
estimating a conveyance load when a motor provided in the printer device conveys a print medium based on the acquired information;
setting a current value to be applied to the motor based on the estimated conveyance load of the print medium;
and
controlling the motor by applying the set current value to the motor;
wherein the acquiring further comprises, at a start of printing, acquiring the temperature of the environment and the printing conditions, and during the printing, acquiring the temperature of the environment and the variable information.
