Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to an improvement of a hand scanner device.

(Prior Art) In a hand scanner, movement in the sub-scanning direction on a document surface is performed manually.

(Problem to be Solved by the Invention) In order to accurately read an original with the hand scanner, it is necessary to linearly move in the sub-scanning direction.

However, manual movement often accompanies meandering, and thus, in some cases, a document cannot be read accurately in the past.

An object of the present invention is to provide a hand scanner device capable of linearly moving in the sub-scanning direction in view of such a situation.

[Structure of device]

(Means for Solving the Problems) The present invention relates to a hand scanner device for reading image information by sliding a casing on a document surface in a sub-scanning direction. A guide plate having an abutment surface orthogonal to a surface, and disposed in the casing, the guide plate being able to protrude and retract between the outside of the sliding surface and the inside of the casing, And a guide plate supporting means movably supporting in the main scanning direction, wherein a contact surface of the guide plate positioned outside the sliding surface is provided on a guide surface along the sub-scanning direction. The sliding direction of the casing is defined by contacting the casing.

(Operation) If the casing is slid while the contact surface of the guide plate is in contact with the guide surface, linear sub-scanning is performed. When not in use, the guide plate can be immersed in the casing, and the guide plate can be moved in the main scanning direction according to the document width.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the appearance and usage of a hand scanner according to an embodiment of the present invention. As described below,
This hand scanner device has a casing
The image information is read by sliding 10 in the sub-scanning direction (see the arrow).

As shown in FIG. 2 which is a bottom view of the hand scanner device, a reading element 20 is provided along a longitudinal direction of a casing 10 and the reading element 20 is provided on a front side and a rear side of the reading element 20, respectively. A roller 30 and a guide rail 40 are provided in a manner parallel to 20.

As shown in FIG. 3, the guide rail 40 has a U-shaped cross section that opens downward, and grooves 41 and 42 along the longitudinal direction of the side face are formed on the front and rear inner surfaces so as to face each other. is there. The guide rail 40 is formed integrally with the casing 10.

The base of a sliding block 50 shown in FIG. The sliding block 50 has ridges 51 and 52 formed in the base portion to be fitted in the grooves 41 and 42 of the guide rail 40, and a concave portion 53 for accommodating the guide plate 60 at a lower end thereof. doing.

As shown in FIG. 5, the sliding block 50 has a guide hole 54 extending along the vertical direction, and a spring 55 and a support shaft 61 of the guide plate 60 are fitted into the guide hole 54.

A ball 56 is provided at a portion of the sliding block 50 where the convex 51 is formed so as to be able to move back and forth and roll. The ball 56 is urged toward the groove 41 by a spring 57, and when the sliding block 50 is slid to a predetermined position, a part of the ball 56 fits into a concave portion 41a provided on the side surface of the groove 41. Are combined.

The recesses 41a are formed at positions corresponding to the positions of the triangular marks shown in FIG. Therefore, the detent mechanism including the ball 56 and the concave portion 41a operates when the guide plate 60 is moved to the position of each triangular mark.

On the other hand, as shown in FIG. 6 which is a cross-sectional view taken along the line BB of FIG. 5, a lock lever 58 is swingably supported beside the guide hole 54.

Now, when the guide plate 60 is pressed in the direction of the arrow, the support shaft 61 moves upward against the spring 55, and accordingly, the protrusion 61a provided on the support shaft 61 approaches the tip of the lock lever 58. Then, when the projection 61a contacts the tip of the lock lever 58, the lever 58 is swung clockwise against the spring 58a,
When the support shaft 61 is further moved, the protrusion 61a is engaged with the tip of the lock lever 58 as shown in FIG.

At this time, the guide plate 60 is immersed in the concave portion 53 shown in FIG. The lower surface of the guide plate 60 has the sliding surface 10 of the casing 10.
will match b.

Next, means for unlocking the guide plate 60 will be described.

A rod 7 for unlocking is provided on the left wall 10a of the casing 10.
0 is slidably provided, and in a state where the sliding block 50 is in contact with the inner surface of the left wall 10a, the tip of the rod 70 is inserted through a hole 59 provided in the block 50. The lever 58 is in contact with the lower rear surface.

Therefore, the rod 7 protruding from the outer surface of the left wall 10a
If the rear end of the lever 0 is pushed in against the spring 71, the lever 58 swings clockwise to unlock the guide plate 60, and as a result, the guide plate 60 slides with the urging force of the spring 55. It is pushed out of the concave portion 53 of the block 50.

In this state, as shown in FIG. 3, the guide plate 60 moves the sliding surface 10 of the casing 10 along the sub-scanning direction.
Projects below b (lower opening surface).

As described above, the sliding block 50 and the guide rail
The reference numeral 40 serves to support the guide plate 60 so as to be able to protrude and retract between the outside of the sliding surface 10b of the casing 10 and the inside of the casing and to be movable in the main scanning direction.

When using the hand scanner of this embodiment, as shown in FIG. 1, the side edge of the document 80 is made to extend along the linear side surface 90a of the document table 90 (for example, a desk). And
After aligning the guide plate 60 with the leftmost triangular mark, the casing 10 is slid in the arrow direction, that is, in the sub-scanning direction, while the inner side surface (contact surface) of the guide plate 60 is in contact with the side edge 90a. Move.

As a result, the original 80 is linearly sub-scanned by the reading element 20, whereby the image information of the original 80 is accurately read by the reading element 20.

When reading a narrow document, the guide plate 60 is aligned with the inner triangular mark. Each triangular mark attached to the other end of the casing 10 is used as a positioning marker for the guide plate 60 when the straight side surface on the opposite side of the document table 90 is used as the guide side surface 90a.

The positioning of the guide plate 60 with respect to the triangular mark is performed by gripping the guide plate 60 by hand and sliding the sliding block 50 along the guide rail 40.

When the reading of the original 80 is completed, the sliding block 50
Is moved to the leftmost end, and then the guide plate 60 is stored in the sliding block 50 as shown in FIG.

In FIG. 1, the side surface 90a of the document table 90 is used as a guide surface. However, when reading the book 100 shown in FIG. 8, the upper end surface 100a or the lower end surface of the book 100 or the side end surface is used. Can be used as a guide surface.

[Effect of the invention]

According to the present invention, since the movement in the sub-scanning direction can be performed linearly, it is possible to prevent the reading error of the original due to the meandering of the sub-scanning and to improve the reading accuracy.

Further, if the guide plate is left protruding, the portability is impaired, and there is a possibility that the guide plate may be damaged when being carried. However, according to the present invention, the guide plate can be immersed in the casing. Portability is improved and breakage of the guide plate is prevented.

Further, since the guide plate can be displaced in the main scanning direction, it is possible to cope with various document widths.
