A detection apparatus includes a second detection unit configured to detect lowering of a light reflectance of a reflection portion based on an output value based on light received by a light receiving portion while an object is moving on a conveyance path, without depending on at least a part of output values output based on light received by the receiving unit while the object is stopped on the conveyance path.

A printing apparatus includes a print execution device and an illumination device. The print execution device includes a plurality of heads to print an image on a print medium based on print data. The illumination device irradiates the printed image on the print medium with illumination light from behind a printed face of the print medium.

The present disclosure relates to the technical field of backlight code printing, and provides a backlight position correction device, which includes an assembly line and an alignment mechanism. The assembly line is configured to drive linear motion of the backlight; and the alignment mechanism is used to adjust a plurality of back-up backlights such that the backlights are in the same straight line. The alignment mechanism includes a fixing plate and a motion component. The fixing plate is disposed at a side of the assembly line. The motion component is disposed at a side of the assembly line opposite to the fixing plate, and configured to push a side of the backlight such that the backlight abuts against the fixing plate.

A printing apparatus in which the movement of a moving body moving inside the housing can be known from outside the housing is provided. The printing apparatus includes a housing, a pair of rotary blades that are disposed inside the housing and move in a scanning direction, a discharge opening that is disposed at the housing so as to pass therethrough and discharges, from within the housing, a medium on which printing is performed inside the housing, and a light source that is disposed inside the housing so as to be elongated in the scanning direction. In the printing apparatus, the pair of rotary blades and the light source are disposed such that reflected light, which is the light emitted by the light source and reflected by the pair of rotary blades, exits the housing through the discharge opening.
