Abstract: An image forming device is disclosed which collects sounds in the vicinity of the image forming device, and then determines the characteristics of the collected sounds. The image forming device will then select an operation mode based upon the characteristics of the collected sounds, and will generate notification sounds and operate in accordance with the selected operation mode.

Abstract: A scanning-member-stop positioning device for the image forming apparatus, wherein a document in contact with a document glass plate is exposed due to the movement of a scanning member consisting of an optical section or a document glass plate, will execute a precise braking control in which a suitable degree of the brake power determined by the actual run to stop the scanning member just at the home position. Accordingly the present invention should be characterized about what the brake power, started at the timing of the passage over the fixed position against the scanning member running back toward the home position in the fixed velocity, is changed the degree, and about what the suitable degree of the brake power is determined by operation corresponding to the moving distances given as a result of the change.

Abstract: An electrostatic copying apparatus and an auxiliary unit detachably mounted on the electrostatic copying apparatus to diversify the mode of image formation. The electrostatic copying apparatus includes a paper conveying passage, a paper feed means for feeding paper to the paper conveying passage and a paper feed passage having its downstream end connected to the paper conveying passage, and a copied image is formed on one surface of paper while it is conveyed through the paper conveying passage after being introduced into the conveying passage from the paper feed means or the paper feed passage. The auxiliary unit includes a paper moving passage whose upstream end is to be selectively connected to the downstream end of the paper conveying passage of the copying apparatus and a paper stock means whose upstream end is connected to the downstream end of the paper moving passage and whose downstream end is connected to the upstream end of the paper feed passage of the copying apparatus.
