<P>PROBLEM TO BE SOLVED: To provide an image formation device capable of facilitating a miniaturization of the device, a control method of the image formation device and a control program of the image formation device. <P>SOLUTION: An MFP as the image formation device includes a vertical conveyance motor 100, a body side control substrate 200 and sensors 1 and 2. In the vertical conveyance motor 100, an encoder 103 generates an encoder signal 405 having a frequency corresponded to revolution of the vertical conveyance motor 100, and a sensor signal superposing section 113 receives logic stated inputs of the sensors 1 and 2. The sensor signal superposing section 113 superposes the logic states of the sensors 1 and 2 to the encoder signal 405 by modulating a duty ratio of the encoder signal 405 based on the logic state of the sensors 1 and 2 to output an encoder signal 401 of after superposition. In the body side control substrate 200, a sensor signal separation section 203 obtains the logic state of the sensors 1 and 2 by demodulating the input encoder signal 401. <P>COPYRIGHT: (C)2013,JPO&INPIT |
