Abstract:
1. A thin type display device comprising: a display portion which is equipped with a screen to display image; a pedestal portion to support the display portion; a connecting portion to connect the pedestal portion and the display portion; a swivel mechanism which is set up in the connecting portion to rotate the display portion in horizontal direction; a motor which gives rotating force to the swivel mechanism; an infrared light receiving portion which receives an infrared signal output from a remote controller for instructing operations to instruct driving of the swivel mechanism; a signal converting portion which converts the infrared signal that is received in the infrared light receiving portion into a control signal; a main control portion which confirms content of the instruction by analyzing the control signal from the signal converting portion; a motor driver to drive the motor by a signal output from the main control portion; and an operating voltage control portion to which a signal is input from the main control portion and generates a voltage switching signal to switch operating voltage of the motor that is supplied from the motor driver, wherein the motor generates a torque corresponding to the operating voltage, and when the main control portion recognizes to start driving of the swivel mechanism based on the infrared signal that is output from the remote controller and is received in the infrared light receiving portion, the operating voltage control portion increases the torque stepwise by generating the voltage switching signal such that the operating voltage is switched and raised stepwise and the operating voltage is made a maximum value after a prescribed time length is passed from the starting of driving.
