As described above, according to the image forming apparatus of the present embodiment, the following effects can be obtained.
Since the control unit 40 controls the illumination unit 70 that illuminates the interior based on the irradiation specifications, the interior can be more suitably illuminated according to the purpose of the illumination. As a result, the situation inside the printer 100 can be more easily recognized.

  Also, based on the irradiation specifications, the illumination light intensity, color, irradiation area, irradiation time, irradiation timing, flashing pattern, etc. can be changed for illumination, which increases convenience for the operator and makes the interior more suitable. Can be illuminated.

  In addition, since the illumination light irradiation specification can be changed by an input from the operation panel 50, a specification that can illuminate the interior more appropriately can be set according to the situation inside the printer 100.

  Moreover, since the some light source with which the illumination part 70 is provided can be controlled independently by the control part 40, the inside can be illuminated more suitably, such as the area to be illuminated can be selected.

  In addition, since the plurality of light sources included in the illumination unit 70 is configured by an LED array in which a plurality of LEDs configured with RGB three colors are arranged, the color of illumination light that illuminates the interior can be changed more easily.

(Embodiment 2)
Next, a printer 101 (not shown) as an image forming apparatus according to the second embodiment will be described. In the description, the same components as those in the above-described embodiment are denoted by the same reference numerals, and redundant description is omitted.
The hardware configuration of the printer 101 according to the second embodiment is the same as that of the printer 100 according to the first embodiment. In order for the printer 101 to make it easier to visually recognize an image formed on the image forming medium (roll paper 1), the control unit 40 uses the image forming data for the image forming unit 10 to form an image and corresponding irradiation specifications. Based on the above, the illumination unit 70 is controlled. Further, the control unit 40 controls the illumination unit 70 based on the type of the image forming medium (roll paper 1) and the corresponding irradiation specification.
This will be specifically described below.

  The control unit 40 has an image forming data analysis function as its software function. Specifically, for example, the average brightness, average saturation, average hue, and the like of the image can be calculated based on the gradation data for each pixel included in the image formation data. Further, the position of the image to be formed can be known in the width direction of the image forming medium (roll paper 1). For this reason, among the illumination specifications described above, in the illumination of the specifications 1 and 8, the illumination that the image forming unit light source 71 performs on the print region is performed more suitably.

Specifically, the control unit 40 corrects the intensity of the irradiation light according to the average brightness of the image to be formed. That is, for example, for dark images, the intensity of irradiation light is easily increased, and for bright images, for example, correction is performed such as reducing the irradiation intensity for anti-glare.
When printing the discharge check pattern of the nozzle, in the illumination of the specification 8, the discharge check pattern is illuminated with illumination light having a brightness or color that is easily visible according to the color (ink).

In addition, since the nozzle discharge check pattern is not printed over the entire width direction of the wide roll paper 1 but is performed on a part of the area, the area is shifted in the width direction. Thus, the ejection check pattern can be printed a plurality of times without wasting the roll paper 1. That is, when printing the repeated discharge check pattern, the roll paper 1 is rewound and printed while shifting in the width direction so as not to overlap the previously printed position.
At this time, the control unit 40 controls the image forming unit light source 71 to illuminate only the latest ejection check pattern area in accordance with the printing position of the ejection check pattern in the illumination of the specification 8. As a result, the operator can check the latest nozzle discharge status without error.

  In addition, since the degree of reflection of the irradiation light of the image forming unit light source 71 may vary depending on the material of the roll paper 1, the control unit 40 performs image formation based on the type of the roll paper 1 and the corresponding irradiation specification. By controlling the partial light source 71, more suitable illumination is performed. That is, in the illumination of the specifications 1 and 8 among the above-mentioned irradiation specifications, a known roll is previously set so that the intensity of light emitted by the image forming unit light source 71 is suitable for the type of the roll paper 1. A table of suitable irradiation intensity corresponding to the type of paper 1 is prepared. For example, in the case of a material that easily absorbs the irradiation light from the image forming unit light source 71, the intensity is corrected so as to be stronger in order to make it easier to see.

As described above, according to the image forming apparatus of the present embodiment, the following effects can be obtained in addition to the effects of the above-described embodiments.
Since the image forming unit 10 can illuminate the interior with the irradiation specification corresponding to the image forming data for forming an image, it is possible to perform more suitable illumination such as easy viewing by the operator. In addition, since the inside can be illuminated with the irradiation specification corresponding to the type of the image forming medium (roll paper 1), similarly, more suitable illumination can be performed such that the operator can easily see.
