Classification: CPC B | IPC B

Claim 0:
1. A thermal printer, comprising:
a motor configured to convey a sheet for printing;
a thermal head configured to perform printing on the sheet;
a first substrate connected to the motor via a first wiring;
a second substrate connected to the first substrate via a second wiring;
a motor drive circuit on the first substrate;
a first temperature sensor on the first substrate, the first temperature sensor being positioned to detect a first temperature of the motor drive circuit;
a second temperature sensor, the second temperature sensor being on the second substrate and configured to detect a second temperature of an ambient environment where the motor is being used; and
a motor controller configured to:
set a first threshold value for the detected first temperature based on the detected second temperature,
control the motor drive circuit based on the first temperature detected by the first temperature sensor and the second temperature detected by the second temperature sensor, and
stop driving of the motor when the detected first temperature reaches or exceeds the first threshold value.
