Upper cover safety switch (L)
Upper cover safety switch (R)
Right cover sensor
F-2-34
Upper cover safety switch
The microswitch-based upper cover sensors detect opening and closing of the upper cover.
When the upper cover is closed, a switch is depressed to notify the sensor that the cover is closed.
To prevent the uneven fitting of the upper cover, sensors are located on both the right and left sides.
Right cover sensor
The photo interrupter-based right cover sensor detects the opening and closing of the right cover.
When the right cover is closed, the sensor light is cut off by the sensor arm, and this notifies the sensor that the right cover is closed.
MEMO:
When the upper cover is closed, the +26.5 V power is supplied by the power supply to drive the carriage motor and feed motor.
