  • Rotary cutter unit and printer device having the unit
    Patent number: 9032850
    Abstract: A simple and compact rotary cutter unit capable of detecting a home position of a rotary cutter, and a printer device having the rotary cutter unit. A radially outwardly extending fin-shaped detected member is arranged on an end portion of the rotating blade opposed to a second gear of the rotating blade. A photosensor is arranged within a main frame of the printer device so that the photosensor may detect the fin-shaped member when the rotating blade is positioned at the home position. The fin-shaped member and the photosensor are not positioned outside relative to both ends of the rotating blade in relation to the direction of the rotational axis of the rotating blade. Therefore, it is not necessary to increase the width of the printer device due to the presence of the fin-shaped member or the photosensor, whereby the printer device may be compactly constituted.

  • IMAGE FORMING APPARATUS
    Publication number: 20150104208
    Abstract: An image forming apparatus includes an image carrier, a developing device, a bias applying unit, a leak detecting unit, a bias controller and a leak detection controller. The developing device includes a magnetic roller and a developer layer. The bias applying unit applies development biases to the magnetic roller and the developing roller. The leak detecting unit detects a leak generated between the image carrier and the developing roller or a leak generated between the developing roller and the magnetic roller. The leak detection controller performs a leak detecting operation for detecting the value of an inter-peak voltage of the alternating current voltage of the development bias applied to the developing roller, at which the leak is generated, while changing the inter-peak voltage at a time different from that during the developing operation.
