Embodiment Construction

[0029] Below, use Figure 1 ~ Figure 13 A printer 100 (corresponding to an image forming device) is taken as an example to illustrate the embodiment of the present invention. The printer 100 includes a state detection device 1 and a zero-crossing signal generating unit 2. However, each element such as the structure and arrangement described in each embodiment is not intended to limit the scope of the invention but is merely illustrative.

[0030] (Outline of image forming apparatus)

[0031] First, use figure 1 The outline of the printer 100 of the embodiment will be described. figure 1 It is a cross-sectional view showing the schematic structure of the printer 100.

[0032] Such as figure 1 As shown, the printer 100 of this embodiment includes an operation panel 3 (corresponding to a notification unit) installed on the side.

[0033] The operation panel 3 is provided at the front end of the arm 31 which is provided on the upper right side of the printer 100. In addition, the operati...

Abstract

The present invention provides a state detection device, a control method thereof, and an image forming apparatus including the same. The state detection device includes: a heater; a first power line for inputting power from one end side of the heater; a second power line for inputting power from the other end side of the heater; a switch unit provided on the first power line; The prevention unit makes the second power line disconnected when the temperature exceeds a predetermined temperature; and the zero-crossing signal generation unit outputs the zero-crossing signal according to the waveform of the AC power supply, and when the voltage of the first power line is greater than the voltage of the second power line And when the voltage of the second power line is higher than the voltage of the first power line, output zero-crossing signals with different output values.

Description

Technical field [0001] The present invention relates to a state detection device that includes a heater that heats a toner image transferred on a sheet and detects the power supply state of the heater. In addition, it relates to an image forming apparatus including a state detection device. Background technique [0002] Electrical equipment such as image forming apparatuses (for example, printers, multifunction machines, copiers, facsimile devices, etc.) operate using power supplied from AC power sources such as commercial power. Therefore, when the power supply of the image forming apparatus is cut off due to various reasons such as sudden power outages and malfunctions, there is a risk of loss of processed data. In addition, due to a sudden power interruption, damage to the image forming apparatus may also be caused. Therefore, in order to detect whether power is being supplied from the AC power source or the power has been cut off, sometimes a zero-crossing signal is generat...
