[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus in which a control board for controlling each part is arranged at the center of the apparatus.

[0002]

2. Description of the Related Art Conventionally, a control board of a facsimile machine has
Since the electronic components are mounted and have a certain size, the back of the device must be
It was common to arrange them on the side and bottom surfaces. Therefore,
The electrical connection between the control board and components, sensors, recording heads, and the like arranged at various places has been performed using a cord such as a harness.

[0003]

However, the conventional facsimile
If the electrical connection of the control board is performed by using a cord such as a harness as in the case of a similiar device, not only is the harness itself expensive, but also the wiring and connection of the harness require a lot of man-hours, resulting in increased costs. There is. Furthermore, in the internal space of the facsimile machine , it is necessary to consider a place for routing the wiring.
This is one of the problems when trying to reduce the size as much as possible.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a small and low-cost facsimile machine that effectively utilizes the internal space of a facsimile machine.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and the present invention has an apparatus control board disposed inside an apparatus and a reading optical path below the apparatus control board. And a document transport path or a recording paper transport path is disposed above the apparatus control board. In addition,
Akira comprises a connection means for rotatably connecting a recording head to the apparatus control board . Furthermore, the present invention
Is provided with movable means that changes depending on the presence or absence of a document or recording paper or the open / closed state of the apparatus lid, and detection means provided directly on the control board and detecting the state of the apparatus by the movable means. is there.

[0006]

According to the present invention, since the reading optical path and the apparatus control board, the electrical members existing on the document conveyance path or the recording paper conveyance path, and the apparatus control board are close to each other, the internal space of the apparatus is reduced. , A small-sized and low-cost facsimile apparatus can be obtained.

Is a recording head 1 by a spring 22 provided on the base 3.
6 is pressed against the recording roller 17.

The transmission original is inserted from the original insertion slot 23,
The sheet is separated one by one by the separation piece 24 and the automatic paper feed roller 25, is conveyed to a reading position by a conveyance roller 28 on a document conveyance path formed by guide plates 26 and 27, and is discharged after being read by a reading unit described later. The rollers are sequentially discharged by the rollers 29.

At the reading position, a light source 30 provided at an end of the base 3 irradiates a document on a reading glass 31 and its reflected light is reflected by a mirror 33 fixed to a fixing portion 32 formed outsert on the bottom plate 1. , Mirror 3 fixed to fixing portion 34
Reflect at 5. These mirrors 33 and 35 are fixed very easily by inserting a mounting spring 36 from the back surface of the bottom plate 1 while being mounted on the fixing portions 32 and 34. The attachment springs are provided with locking portions 37 and 38 so that once attached, they do not fall off.

Further, the reflected light from the mirror 35 is transmitted to the bottom plate 1.
After being reflected by a mirror 40 fixed by a mounting spring 41 to a fixing portion 39 formed by outsert molding, the CCD
Light enters at 42. In the present embodiment, the CCD 42 is a harness
Although not shown, it is connected to the control board 4, but of course, it can be directly provided on the back surface of the control board 4.

Reference numerals 43 and 44 denote posts for fixing the base 3 to the center of the facsimile apparatus.

As described above, the apparatus control board is arranged inside the apparatus, and the reading optical path is arranged below the apparatus control board.
A document conveyance path and a recording paper conveyance path are arranged above the apparatus control board, sensors are provided directly on the apparatus control board, and a recording head is rotatably connected to the control board. FIG. 2 is a schematic perspective view of a main part of the facsimile apparatus.
This will be described in more detail with reference to FIG.

In FIG. 2, reference numeral 20a denotes a connection member provided directly on the control board 4, and reference numeral 20b denotes a connection member provided on the head mounting portion, and electrically connects the control board 4 and the recording head via the connection member 20a. Reference numeral 45 denotes a bearing for rotatably holding the actuator 12, and reference numeral 46 denotes a bearing for rotatably holding the actuator 11.

As shown in FIG. 2, the connecting members 20a, 20a
b are connected to each other while biting into each other, and these grooves are configured to conduct electricity with a conductor. The shaft 21 and the connecting member 20 in the head mounting portion 19 are configured to be rotatable while conducting electricity. In this manner, the head mounting portion 19 is disposed directly on the control board 4 while being able to press against the recording roller 17.

As shown in FIG. 1, the control board 4 is provided with sensors 7, 8, 9 and the base 3 is provided with bearings 45, 46 for the actuators 11, 12. Then, the actuators 11 and 12 rotatably held by the bearings 45 and 46 rotate according to the presence or absence of a document, the open / close state of an opening / closing cover of a reading system and a recording system,
Each of the sensors 7, 8, 9 will be detected.

Next, the operating state of each of the sensors 7, 8, 9 will be described with reference to FIGS.

3 to 6, reference numeral 47 denotes a stopper provided on the reading system opening / closing cover, 48 denotes a stopper provided on the recording system opening / closing cover, 49 denotes a recording system opening / closing cover, and 50 denotes a recording system opening / closing cover. The axis | shaft which opens and closes the cover 49 is shown.

FIG. 3 shows that the original does not pass through the original transport path.
The state when the reading system opening / closing cover and the recording system opening / closing cover 49 are closed is shown. At this time, the actuator 11 and the actuator 12 block the document conveying path as shown in FIG. 3, and the document sensor 7 and the document sensor 8 detect the actuators 11 and 12, respectively. On the other hand, since the reading system open / close sensor 9 has the stopper 49,
The actuator 11 has not been detected. As a result, it is confirmed that there is no original and the cover is closed in a normal state.

FIG. 4 shows a state in which a document passes through the document conveying path and the reading system opening / closing cover and the recording system opening / closing cover 49 are closed. At this time, as shown in FIG. 4, the actuator 11 and the actuator 12 are pushed down under the document conveyance path because the document is in the document conveyance path.
The original sensors 7, 8 and the open / close sensor 9 do not detect the actuators 11, 12. Thus, it is confirmed that the document is being conveyed.

FIG. 5 shows a state where the reading system opening / closing cover and the recording system opening / closing cover 49 are open. At this time, since the stopper 47 and the stopper 48 are raised, the actuator 11 pressed by these stoppers is lowered to the lower right, and the open / close sensor 9 detects the actuator 11 together with the document sensor 8. Thereby, it is confirmed that the reading system opening / closing unit is open.

[0027]

As described above, according to the present invention, an apparatus control board is arranged inside an apparatus, a reading optical path is arranged below the apparatus control board, and a document conveying path or a recording paper conveying is arranged above the apparatus control board. By arranging the paths, the reading optical path and the apparatus control board, the electrical members existing on the document conveyance path or the recording paper conveyance path, and the apparatus control board are close to each other, so that the internal space of the facsimile apparatus is effectively used. However, the present invention has an effect that the size and cost of the device can be reduced.
