Embodiment Construction

[0030] 1. Exemplary implementation

[0031] Image forming apparatuses such as printers and copiers may include an openable cover provided at one side or the other side of a casing of the apparatus. Such a cover enables replacement or maintenance of components, etc., or enables operations of adjusting paper jams, etc., in the device. In the exemplary embodiment, this type of image forming apparatus is described as an example. figure 1 is a perspective view of the exterior of the image forming apparatus on which the housing according to the exemplary embodiment is provided. figure 2 is a schematic diagram of the structure of the casing of the image forming apparatus.

[0032] Structure of Image Forming Device

[0033] Such as figure 1 As shown, the exterior of the image forming apparatus 1 generally includes a box-shaped apparatus main body 51 . An external cover 52 is openably provided on the front surface of the device main body 51 . When the exterior cover 52 is opened...

Abstract

A sensor device includes: a member that has an aperture facing a target measuring position through which a target to be measured passes; a sensor that is provided in an opposing relation to the target measuring position, and that measures a physical quantity of the target at a sensor surface facing the aperture; and a moving member that reciprocates a movement in a predetermined direction, and includes: a cleaning unit that cleans the sensor surface by contacting the sensor surface while the moving member moves to at least one of an outward movement and a return reciprocal movement; an applying portion that applies to the moving member a force in one direction of the reciprocation movement; and a manipulation portion that is moved by an operator against the force applied by the applying portion in an direction opposite to that of a direction of the force.

Description

technical field [0001] The present invention relates to a sensing device and an image forming device. Background technique [0002] In an image forming apparatus, for example, a sensor that measures a physical quantity is used as a toner density sensor or an alignment sensor. Such a sensing device needs to be arranged at a position where unfixed toner passes. By being arranged at such a position, the sensing device is susceptible to contamination by toner spray attached to the device. Japanese Patent Laid-Open (JP-A) No. 2000-39579 describes a switch that mechanically closes an opening portion facing a sensing device when a unit is removed from a housing. Japanese Patent Laid-Open (JP-A) No. 2004-279671 describes a structure in which a sensor for measuring the toner density is arranged at a window provided with a switch when the toner density is to be measured. The switch covers the window when the sensor is not in active use, and when covered by the switch, the surface o...
