Description

[Detailed Description of the Invention] (Technical Field of the Invention) This invention relates to a color scanner output drum with a safety mark, in which a safety mark for preventing danger is provided on the color scanner output drum.

(Technical background of the invention and its problems) Conventionally, color scanners are known that utilize photoelectricity to create corrected negatives or positives for multicolor printing. Such a color scanner is installed in a darkroom in order to load a photosensitive material into the color scanner output unit, and replacement of the photosensitive material is also performed under a safe light inside the darkroom. Furthermore, the output unit and the output drum within the output unit are usually painted black to prevent light scattering. For this reason, it has been difficult for an operator to visually determine whether the output drum is rotating or stopped. On the other hand, the output drum is equipped with a brake, and when the output unit lid is opened at the end of color scanner work or for inspection or repair, the brake works to stop the rotation of the output drum. However, since the output drum rotates at high speed, it does not come to a complete stop immediately due to inertia. For this reason, there was a risk that the worker would accidentally come into contact with the rotating output drum.

(Purpose of the invention) This invention was made due to the above-mentioned circumstances, and the purpose of this invention is to provide a visible safety mark on the output drum surface of a color scanner so that the rotation of the output drum can be controlled even in a dark room. To provide a color scanner output drum with a safety mark that can be easily checked and does not pose any danger to work.

(Summary of the invention) This invention relates to a color scanner output drum with a safety mark, in which a visually visible safety mark is provided on the output drum surface of the color scanner along the rotational direction.

((Embodiment of the invention) The attached figure schematically shows a color scanner 10 using a color scanner output drum with a safety mark, which is an embodiment of the invention. The color scanner 10 is designed to operate under the control of the user.The color scanner 10 is provided with a cover 11 for replacing photosensitive materials, and is designed to be used by opening it in the direction A in the figure.Color scanner 1
A color scanner output drum (hereinafter referred to as the output drum) 1 with a safety mark is provided inside the printer.
The output drum 1 is loaded with a photosensitive material 3 and rotated in the direction B in the figure, and a light source (not shown) is scanned parallel to the output drum 1, so that the photosensitive material 3 is exposed. On the left side of the output drum 1,
A dotted line or striped safety mark 2 is printed or layered on the circumference along the rotation direction (direction A in the figure), and this safety mark 2 makes it easy to work even under a safe light in a dark room. The color is clearly visible (for example, white). Furthermore, the output drum 1 is provided with a brake (not shown), which is activated to stop the rotation of the output drum 1 when the color scanner 10 finishes the exposure operation and when the photosensitive material replacement lid 11 is opened (in the direction A in the figure). The operation is notified by a buzzer etc.

In such a configuration, the color scanner 10
The operation will be explained. First, the operator opens the photosensitive material replacement lid 11 of the color scanner 10 in the direction A, loads the photosensitive material 3 onto the output drum 1, and
The photosensitive material replacement lid 11 is closed and the controller device is operated to operate the color scanner device 10.
Then, the output drum 1 rotates in the direction B, and the photosensitive material 3 is exposed. When the exposure of the photosensitive material 3 is completed, the brake of the output drum 1 is automatically activated to stop the rotation of the output drum 1, and a buzzer is sounded to warn that the operation has ended. Therefore, the operator opens the photosensitive material exchange lid 11 and takes out the photosensitive material 3, but in this case, the output drum 1
Since the rotation does not stop immediately due to inertia, the rotation is confirmed by looking at the safety mark 2 provided on the output drum 1, and the extraction operation is performed after the rotation has completely stopped. In addition, photosensitive materials 3 are used for inspection and repair.
When opening the photosensitive material replacement lid 11 during exposure, the brake is activated and the output drum 1 is stopped, so the operation is carried out after the rotation has completely stopped as described above. In this way, the operator does not come into contact with the rotating output drum 1, so the operator can work safely.

(Effects of the invention) As described above, according to the color scanner output drum with a safety mark of this invention, the safety mark provided on the output drum allows the operator to easily check the rotation of the output drum even in a dark room, and the photosensitive material This has the effect that it is possible to safely perform work such as replacing the output drum, repairing the output drum, and inspecting the output drum.
