Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a manual image input device that manually performs sub-scanning and inputs image information.

"Conventional technology" A conventional example of a manual image input device is shown in FIG.

The manual image input device inputs image information by placing the input device on an object to be read, such as a document or an image, and manually scanning it in the direction of arrow A in the figure. Therefore, the input device has an image input window 109 on the document contacting surface 113 of the external device 12 that contacts the object to be read, and a timing detection shaft that exposes the sub-scanning timing detection shaft 108 that rolls with the document toward the document surface. It has a window 114, and when manually scanning an image, light from the lamp 103 located inside the image input window 109 is irradiated onto the document through the window, and the image of the document passed through the imaging lens 102 is extracted. The reflected light is transmitted by the belt device 115 from the sub-scanning timing detection shaft 108 to the sensor 101 located inside the image input window 109, and the rotating encoder disk 107 is detected by the encoder photoelectric converter 106. Image information was obtained by reading the image, transferring it to memory, and storing it in accordance with the scanning timing signal. However, since the input device is placed on the object to be read, such as a document or an image, and the reading is performed manually, the reading position is hidden and cannot be seen. For this reason, a reading center position mark 111 is placed at the front position of the exterior work 12.
It has generally been possible to align the image window 109 and the document image manually by providing a reading position mark 110 at a side position in front of the user.

[Problem to be solved by the invention] However, when manual scanning is performed by placing an input device on an object to be read, such as a document or an image, the reading position in the main scanning direction and the sub-scanning direction is The image input window 109 and each position mark 110.
1 is far away from the actual reading position, making it difficult to accurately read the desired image information, making it difficult to use, and causing the intended image information to be missed. was there.

SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a manual image input device that facilitates accurate manual input of desired image information.

[Means for Solving the Problems] The input section is made visible, and a mark is placed beside the reading position in the sub-scanning direction, for example, at a position slightly in front of it.

According to a first aspect of the present invention, in a manual image input device that reads information by manually scanning a document or an image, at least a component of the input portion of the exterior is made of a transparent member so that the input portion can be visually recognized. , or a manual image input device characterized in that an opening is provided in the exterior and a positioning mark is provided immediately adjacent to the reading position.

The second invention of the present invention is characterized in that the alignment mark is provided at a position slightly in front of the reading position and on the document contact surface side of the input section component made of a transparent member. This is a manual image input device according to the invention.

"Examples" The present invention will be described in detail below based on Examples. FIG. 1 is an overall view of a manual image input device according to a first embodiment of the present invention.

An image input window 9 is provided on the document contacting surface 1'3 of the box-shaped exterior work 2.
and a timing detection axis window 14. The next member to be mounted is housed in the exterior work 2 and supported by a support member (not shown). That is, an image signal input device includes a lamp 3 that illuminates the original in contact with the original contact surface 13 through the image input window 9, a lens 2 that forms an image of light reflected from the original on the sensor 1, and a line sensor 1 that reads one line of the original. A reading timing detecting shaft 8 whose outer periphery is exposed to the outside of the exterior work 2 through the window 14 for the device and timing detecting shaft, and a belt 1 wound around the reading timing detecting shaft 8 and the pulley 16.
In the exterior work 2, there is provided a reading input timing device consisting of a belt device consisting of a belt device 7, an encoder disk 7 which is coaxial and integral with the pulley 16 and is rotatable, and a photoelectric converter 6 for the encoder that generates pulses by rotation of the encoder disk 7. It is accommodated.

A target image is illuminated by a lamp 3, and reflected light from the image is focused on a sensor 1 through a lens 2. The information imaged on the sensor 1 is determined by the rotation of the reading timing detection shaft 8 being transmitted to the encoder disk 7 via the belt 17 and the pulley 16, and the reading timing according to the rotation of the encoder disk 7 by the encoder photoelectric converter 6. Each time a line is generated, one line is read by the licensor 1.

Here, in order to make the input part visible, a part of the input part component member 4 of the exterior work 2 is made of a transparent material, and the document contact surface 13 is made of a transparent material.
A reading center position mark 1 is placed on the top surface of the unit, near the image input window 9 in the sub-scanning direction, for example, at a position slightly in front of the reading position.
0 is set. Further, reading width marks 5.5 are provided on both sides of the mark 10 to indicate the reading width in the main scanning direction.

In the above configuration, the user manually aligns the mark 10 and the marks 5, 5 with respect to the object to be read through the input part component 4 made of a transparent material so that the input part is visible. It is also possible to read in the sub-scanning direction.

Therefore, since the mark 10 and the marks 5, 5 are provided at positions extremely close to the reading position, it is easy to align the reading position.

"Other Embodiments" FIG. 3 shows a second embodiment of the present invention. FIG. 4 is an enlarged cross-sectional view of the main part of the second embodiment of the present invention. In the same figure, the difference from the first embodiment is that a reading mark 10' is provided on the document contacting surface 13 side of the input section component member 4 that can be seen through the transparent member. The parallax caused by the thickness of the document contacting surface 13 of No. 4 is eliminated, and reading and positioning can now be performed with high accuracy.

That is, since the center position mark 10 is shown in FIG. 1, the center position is shifted, and the width direction perpendicular to the scanning direction is also b in FIG. In this embodiment, the center position mark 10' is aligned with the center of the original image, so that there is no misreading when looking at the width b'.

FIG. 5 is a perspective view of still another embodiment. In this embodiment, 1 to 3 of the 4 surfaces that stand up from the original contact surface 13 of the input section component 4 are removed to create, for example, openings 18 to 20, and openings 18 and 20 are provided. Walls 21 and 22 are left on the front and rear walls of the input section component 4 to maintain the strength of the outer device 2. There is no difference in that the original contact surface 13 is made of a transparent member.

[Effect of the invention 1] As described above, according to the present invention, it is possible to visually recognize the area where image information is actually being read and its surroundings during input operations, and positioning marks are provided near the reading position. Therefore, for example, by providing a mark for reading position alignment at a position slightly ahead of the reading position in the sub-scanning direction, it becomes easier to align the position, it becomes easier to input the desired image information reliably, and operability is improved. was able to improve significantly.
