Abstract

PURPOSE:To constitute an optical unit and make an optical member adjusting operation without requiring only a forming member of the optical unit by integrally constructing the optical unit by a bottom plate of a main device. CONSTITUTION:In one side section of a main device, a lens 15 and a CCD 16 as optical members and an optical unit 14 accommodating a circuit substrate or the like are provided. This unit 14 is integrally formed by a bottom plate 22 of the main device in a form of a recess, and a lower end opening section is opened and closed by an opening and closing cover 23. The cover 23 is removably attached by an attaching screw 24. In this manner, the unit 14 is integrally constituted by the bottom plate 22, so that a forming member of the optical unit is not required separately, but the unit 14 can be constituted. An assembling operability is improved and an adjusting operation of the optical members can be easily executed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an image forming apparatus used, for example, as a scanner copier apparatus.

[Technical background of the invention and its problems]

A general scanner copier device is designed to read a document by a reading means that runs on the document table, and then generates thermal heat based on the read information to form a document image on a sheet of paper. .

The above-mentioned reading means usually includes a carry, a rung, and a mirror, and also includes a lens and a sensor in an optical unit, and scans the document with light by emitting light from the run and moving the carriage. The image is read by focusing the reflected light onto the sensor via the lens.

However, in the past, a single molded member was required for the optical unit, which resulted in a large number of parts, high costs, large assembly man-hours, and troublesome positioning. There are six disadvantages that take time.

Further, when adjusting the lenses in the optical unit, the cover of the copier device must be removed and then the opening/closing lid of the optical unit must be opened, making the adjustment work troublesome.

[Purpose of the invention]

The present invention has been made in view of the above circumstances.

The object thereof is to provide an image forming apparatus in which an optical unit can be constructed without requiring a separate molded member for the optical unit, and in which adjustment of the optical member is easy.

[Summary of the invention]

In order to achieve the above object, the present invention integrates the optical unit with the bottom plate of the main body of the device, so that the molded parts of the optical unit and the bottom plate are shared, and the optical unit can be easily opened. is.

[Embodiments of the invention]

Hereinafter, the present invention will be described with reference to an embodiment shown in the drawings. Figure 1 shows the Sugyaner copier device.
is the main body of the device. A document table 2 is provided on the upper surface of the apparatus main body 1, and a document 21 is set on the document table 2 and is opened and closed by a document cover 3.

Further, a reading means 4 is provided in the apparatus main body 1 at a lower side of the document table 2. As shown in FIG. This reading means 4 is constructed as shown in FIG. In other words, 5. in the figure.
Reference numeral 6 designates first and second units, in which an LED array 7 and a first mirror 8 are arranged, as shown in FIG. A second and third mirror 9, 10 are arranged.

The first and second units 5.6 are driven by a driving means (not shown) so that their front and rear ends are supported by the idle rails 11, 12 and run along the direction of the arrow shown in FIG. It is shown in The height of the first guide rail 11 is larger than that of the second guide rail 12, and the first and second units 5.6 are supported in a tilted state perpendicular to the direction of travel thereof. has been done. Further, a locking piece 13 is provided protruding from the rear end side of the first and second units) 5 and 6, and this locking piece 13 is connected to the first unit.
The guide rail 11 restricts movement of the first and second units 5.6 in the inclination direction due to their own weight. Note that the first and second units 5 and 6 are inclined at 0 degrees with respect to the horizontal plane, and try to move in the direction of arrow F due to their own weight G.

Furthermore, as shown in FIG. 5, one side of the apparatus main body 1 includes a lens 15 and a CCD 16 as optical members, and an optical unit 1 that houses a circuit board (not shown).
4 is provided.

The optical unit 14 is integrally formed in a concave shape with the bottom plate 22 of the apparatus main body 1, and its lower end opening J4a is opened and closed by an opening/closing lid 23. The opening/closing lid 23 is detachably attached using attachment screws 24.

On the other hand, a printer section 17 is provided on the rear side of the apparatus main body 1. The printer section 17 is composed of a platen 18 and a thermal head 19 that approaches and separates from the platen 18. The thermal head 19 generates heat based on image reading information from the CCD 16 and transfers an image onto the paper P.

When forming an image, the LED array 7 emits light and irradiates the document G with light (the first and second unit y) 5h6 is connected to the guide rail 11.12.
The entire surface of the document 21 is scanned.

During this scan, the reflected light from the document 21 is reflected from the lens 1.
5, the CCD 161c forms an image and reads the image. Then, the thermal head 19 generates heat based on this image reading information, and prints the paper PK ink. (not shown)
An image is formed by transferring the ink.

Now, a case will be explained in which all the adjustments of the lens 15 of the optical unit 14 are performed. At this time, as shown in FIG. 7, remove the screws 24 of the opening/closing lid 23 from the bottom side of the main body 1, remove the opening/closing lid 23t, and then open the optical unit.
y) Open 14 and adjust the lens.

As mentioned above, according to this embodiment, the optical unit) J
Since the bottom plate 22 of the 4t-apparatus main body 1 is integrally constructed, the number of parts can be reduced and the number of assembly steps can be reduced, and positioning of the optical unit 14 is not required.

In addition, when adjusting the lens 15, the optical unit 14 can be opened simply by removing the opening/closing lid 23, resulting in excellent workability.

Note that the present invention is not limited to the above embodiment,
Of course, various modifications can be made within the scope of the gist.

〔Effect of the invention〕

As explained above, in the present invention, since the optical unit (y) is integrally formed with the bottom plate of the main body of the apparatus, there is no need for a special molded member (t) of the optical unit, and the number of parts can be reduced and the cost can be reduced. This provides excellent assembly workability, eliminates the need for positioning work for the optical unit, and allows the optical unit to be opened in one operation when adjusting optical members, making the adjustment work easier.
