Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an optical reading device that optically reads characters, etc. on a sheet-like medium such as paper or a card.

<Prior art> An optical reading device has been designed to be able to change the relative position of a reading section for reading characters, etc. and a track for passing paper, cards, etc. printed with characters, etc. to be read. For example, even when reading a sheet-like medium on which characters or the like are attached by printing or the like at various positions, it is possible to read the characters or the like at the various positions.

The optical reading devices shown in FIGS. 4 and 5 are capable of performing this in the following manner, respectively.

That is, in FIG. 4, a character reading section 1 that optically reads characters and converts them into electrical signals is fixed to a frame 2, and the frame 2 is a track for passing paper, cards, etc. on which characters are attached. The character reading section 1 is supported by a shaft 5 so as to be movable up and down so that the character reading section 1 is located at an opening 4 formed facing the character reading section 3. A frame 2 to which the character reading section 1 is fixed has a convex portion 6, and this convex portion 6 engages with a groove 8 of a lamp 7. And the above lamp 7
is provided with an adjustment screw 9, and by moving it as shown by the arrow a shown in the figure B, the frame 2 is guided by the shaft 5 and moves up and down as shown by the arrow b, thereby adjusting the character. The relative position between the reading section 1 and the track 2 can be changed.

In the case of FIG. 5, a position adjustment dial 11 with a helical lamp is provided at the bottom of the case 10, and the truck 3 can move up and down with respect to the case 10. If you turn it, the arrow c shown in A and B in the same figure
The track moves up and down as shown, and the relative position between the character reading section 1 and the track 3 can be changed. Note that P is the center of the reading section.

In this way, in the case of Fig. 4, by moving the screw 9 attached to the lamp 7 to move the frame 2 up and down, and by changing the height from the bottom of the OCR track 3, a sheet-like structure can be attached to the track 3. When reading characters etc. optically through a medium, it is possible to read characters etc. in various positions, but the adjustment screw 9 is located on the bottom surface of the device body, making it difficult to operate, and it is difficult to read the center of the scanner. There are no items, the location of the scanner is unknown, and adjustments are not quick enough.

In the case of FIG. 5, by turning the position adjustment dial 11 with a helical lamp, the track 3 can be moved up and down with a helical lamp, and in the same way it is possible to correspond to characters etc. in various positions.
This takes up space, and furthermore, the helical lamp cannot be wound twice, leading to an increase in the size of the device in order to obtain the required vertical movement.

<Problems to be solved by the invention> The present invention was developed in view of the difficulty in adjusting the position of the reading section and the problem of increasing the size of the device. It is an object of the present invention to provide an optical reading device that can prevent the device from increasing in size.

<Means for Solving the Problems> In order to achieve the above object, the optical reading device of the present invention passes a sheet-like medium through a track and reads characters etc. optically using a reading section that converts them into electrical signals. a mechanism for adjusting the position of the reading section by moving it in a direction perpendicular to the track using a helical cam, a knob provided on a side surface of the device for rotating the helical cam, and the adjustment mechanism. The apparatus is characterized in that it has a display mechanism that includes a display section that indicates the adjustment position of the reading section in conjunction with the reading section, and an opening that allows the display section to be viewed.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 shows the configuration of an optical reading device according to an embodiment of the present invention.

This optical reading device has a reading section that optically reads characters and converts them into electrical signals, and a track (document track) through which paper, cards, etc. are passed. Adjust by moving it vertically. Further, a knob for vertically moving and adjusting the reading section using a helical cam is provided on the side of the device, and a display mechanism is also provided so that the operator can visually confirm the adjustment position from the outside during the adjustment.

That is, in FIG. 1, a character reading section 1 is fixed to a frame 12 as shown, and a protrusion 13 of the frame 12 is fitted into a groove 15 of a helical cam 14. One of the shafts 5 that supports the frame 12 in a vertically movable manner is also used as the shaft of the helical cam 14 in this example. The helical cam 14 has a groove 15 formed on the circumferential surface of a bobbin, and the groove 15 can be wound a plurality of times, and in the illustrated example, it is wound twice.

A position adjustment dial 16 with a helical cam is provided on the side of the device near the truck 3, and is used to move the frame 12 up and down as shown by arrow b in FIG.

Further, the frame 12 is provided with a display section 17 at the center of the character reading section, and correspondingly, the case 18 has an opening section 19 formed on the dial side. These display section 17 and opening section 19 constitute a display mechanism for grasping the adjustment position from the outside during adjustment, and in the illustrated case, they are on the same side as the position adjustment dial 16.

In the embodiment device having the above configuration, the character reading section 1
When adjusting the position, the operator only has to rotate the position adjustment dial 16 with helical cam.
Convex portion 13 of frame 12 to which character reading section 1 is fixed
is inserted into the groove 15 of the helical cam 14, so when it is rotated as described above, the character reading section 1 is moved perpendicularly to the track 3 via the frame 12, thereby adjusting the position.

In this way, the character reading section 1 is fixed to the frame 12, and the convex portion 13 of the frame 12 is connected to the helical cam 1.
4, and position adjustment dial 16.
By rotating the frame 12 to raise and lower the frame 12 and changing the height of the reading section 1 from the bottom of the track 3, even when reading paper or cards with characters to be read in various positions. It can correspond to characters etc. in various positions, and the character reading section 1 can be attached to the frame 12.
An opening 19 is provided in the case 18 on the dial side, and it is possible to see the position adjustment through the opening 19. The position of the character reading section 1 can be easily adjusted using the position adjustment dial 16.
is located on the side near the track 3, and there is something on the same surface that indicates the center of the scanner, making it easy for the operator to adjust the position of the reading section 1. In addition, whereas the helical lamp shown in Fig. 5 cannot be wound twice, the helical cam can be wound twice, so even a small bobbin can make a large vertical movement. The required space is small, and the device does not become larger.
Moreover, in the case of FIG. 5, there is a gap between the recess on the top surface of the case 10 and the track 3, making it difficult to insert paper, etc., but with the above configuration, this does not occur.

FIGS. 2 and 3 show other embodiments of the present invention showing an application example of a method for vertically moving the frame 12,
In the case of Fig. 2, a helical cam 1 is installed separately from the shaft 5 for the frame 12 to which the character reading section 1 is fixed.
