Abstract
A printer includes a motor power supply line connecting a carriage motor with a power source, a sensor power supply line connecting a rotary encoder with the power source, a circuit breaker provided on the motor power supply line and interrupting electrical power if a cover sensor detects that a front cover is open and permit connection if the cover sensor detects that the front cover is closed, and a controller controlling the carriage motor and a recording head based on a position of a carriage detected by the rotary encoder.
Claims6
A printer comprising:
- a casing;
- a guide rail disposed in the casing;
- a carriage engaged with the guide rail;
- a carriage motor coupled to the carriage and causing the carriage to move along the guide rail;
- a recording head provided on the carriage so as to move with the carriage;
- an openable/closable cover fitted to the casing;
- a cover sensor detecting whether the cover is open or closed;
- a position sensor detecting a position of the carriage;
- a motor power supply line connecting the carriage motor with a power source;
- a sensor power supply line connecting the position sensor with the power source;
- a circuit breaker provided on the motor power supply line and opening if the cover sensor detects that the cover is open;
- and
- a controller communicatively connected to the position sensor, the carriage motor, and the recording head, and controlling the carriage motor and the recording head based on the position of the carriage detected by the position sensor, wherein
- the carriage motor is operated when a voltage equal to or higher than a predetermined minimum operating voltage is applied thereto;
- the motor power supply line applies a voltage equal to or higher than the predetermined minimum operating voltage to the carriage motor;
- and
- the sensor power supply line applies a voltage lower than the predetermined minimum operating voltage to the position sensor.
