Abstract: A laser marking system in one aspect of the present disclosure includes a laser marker, a beam receiving device, and a notifier. The laser marker includes a laser beam emitter. The beam receiving device includes a beam receiver and a transmitter. The beam receiver receives a laser beam emitted by the laser beam emitter. The transmitter transmits a first positional signal. The first positional signal indicates a receiving position of the laser beam in the beam receiver. The notifier notifies of the receiving position of the laser beam based on the first positional signal.

Abstract: A display control method in one aspect of the present disclosure includes: displaying a position image; acquiring a relevant signal; and rotating the position image. Displaying a position image includes displaying a position image in a specified direction with respect to a background image of a screen of a portable terminal device. Rotating the position image includes rotating the position image with respect to the background image so that an image direction matches a device direction.

Abstract: A laser marker according to one aspect of the present disclosure includes: a laser emitter; an information reception circuit; a measuring circuit; and a disabling circuit. The measuring circuit starts to measure an elapsed time in response to the information reception circuit receiving an enabled time. The disabling circuit disables the laser marker for operating in response to a length of the elapsed time reaching or having reached a length of the enabled time.

Abstract: A laser marker in one aspect of the present disclosure includes a support body, a rotation body, a motor, a laser beam emitter, a device communicator, and a motor control circuit. The device communicator performs a wireless communication with a portable terminal device and with a beam receiving device. The portable terminal device transmits a rotation start command signal. The beam receiving device generates and transmits a bean receiving position signal. The motor control circuit starts controlling a rotation of the motor based on the beam receiving position signal in response to the device communicator receiving or having received the rotation start command signal.
