Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transmitting/receiving facsimile device, and more particularly to a plane scanning type transmitting/receiving facsimile device.

Traditionally, this type of facsimile counterfeiting has been done with a recorder.
There is a transmitter/receiver type that uses a thermal recording method and is capable of transmitting and receiving, but the recording head becomes dirty due to oxides generated from the recording paper or accumulated dust inside the machine. It was necessary to clean the recording head section from time to time. However, since the recording head section is attached to the main body side, it is necessary to remove the recording head section from the main body side and clean it, which is extremely troublesome and also makes it difficult to replace and load recording paper, etc.

SUMMARY OF THE INVENTION An object of the present invention is to provide a transmitting/receiving facsimile device which eliminates the above-mentioned drawbacks of the prior art and is easy to handle and maintain.

In order to achieve this object, the present invention provides a bonito body with a main body case forming a lower part and a part of an upper part of the bonito body, and a main body case forming a part of the upper part of a bulge and opening and closing into the main body case. It consists of a cover that can be attached freely, and a storage section for recording paper, a base feeding mechanism, an optical mechanism for taking the document, and a coupling mechanism for the document are installed on the main body case side, and the recording head is installed inside the cover, and the recording head is installed inside the cover. It is characterized by being attached with its recording portion facing inward so that it will bounce away from the inner surface.

Hereinafter, one embodiment of the present invention will be described in detail based on FIGS. 1 to 4.

In these figures, 1 is the end drive motor (not shown)
A pinch roller 2 is connected to the drive roller 1 and rotates in the direction of rotation shown by the arrow, and a pinch roller 2 is supported below the drive roller 1 so as to be in constant pressure contact with the drive roller 1.

Reference numeral 3 denotes a recording head such as a thermal recording head, which is slidably attached to a support rod 5 fixed to the inside of a cover 4 with its recording surface facing downward, and a push spring 6 is installed between the cover 4 and the recording head 3.
is interposed.

The push spring 6 always springs the recording head 3 in a direction away from the inner surface of the cover 4, and after the cover 4 is clamped and fixed, the drive roller 1 and the recording head 3 are always pressed against each other appropriately. . A fixing hole 7 is formed in the front side of the cover 4, and a hinge is formed between the cover 4 and the main case 8 at the rear by a shaft 9, a coil spring 10, etc., and a clamp 11 is formed.
When the cover 4 is disengaged, the coil spring 10 causes the cover 4 to open as shown in FIG. Note that the pupil body is constituted by the cover 4 and the main body case 8, but the cover 4 forms a part of the upper part of the bonito body, and the other parts are formed by the main body case 8. As shown in FIG. 2, the clamp 11 is made up of a locking piece 14 having a protrusion 12 and a locking part 13 at its tip, and a knob 15. It is attached via a spring 17 and a spring seat 18.

The protrusion 12 is formed slightly higher than the locking part 13, and the protrusion 12 and the locking part 13 engage with the fixing hole 7 in the installed state, and when the knob 15 is pulled forward, the protrusion 12 or the locking portion 13 is removed from the fixing hole 7, and the cover 4 is opened as shown in FIG. Reference numeral 19 designates a document holder provided at the upper part of the main body case 8, a scarlet paper opening provided in the fixed front cover 16, and reference numeral 21 a document entrance.

22 is a lamp such as a saddle light that illuminates the original, 23 is a mirror, 24 is a projection lens, and 25 is a photoelectric conversion element such as a photo sensor array. 25 has been reassigned.

26 is a recording paper inlet for the recording paper 27 formed on the rear side of the main body case 8; 28 is a document discharge port; 29 is a scarlet paper guide plate; It is rotatably mounted.

Reference numeral 31 is a control section room in which electrical components such as a power supply and a control board are arranged, and 32 is a document paper holder.

The operation of the transmitting/receiving facsimile machine configured as described above will be explained. First, pull the knob 15 of the clamp 11 to open the cover 4.

That is, after installing the recording paper 27 in the state shown in FIG. 4 and setting the recording paper 27 on the drive roller 1, the cover 4 is closed and locked by the clamp 11 and the fixing hole 7. , when you want to send data now, as shown in FIG.
Adjust by rotating 5. If you transmit in this state, it will be the same as the subordinate transmitter, and since a gap g will be created between the recording head 3 and the drive roller 1, the recording paper 27 and the drive roller 1 will idle, and the recording paper 27 is not emitted. When performing reception, the knob 15 is rotated so that the fixing hole 7 and the protrusion 12 are engaged with each other, so that the recording head 3 and the driving roller 1 are brought into pressure contact with each other, as shown in FIG. Make it.

Therefore, it functions as a conventional receiver, and the recording head 3
The recording paper 27 on which the information has been recorded is discharged from the paper discharge port 20. Also, when using it as a monitor or simply as a copying machine, the fixing hole 7 and the protrusion 12 are engaged with each other as shown in FIG. The head 3 and the drive roller 1 are brought into pressure contact,
The original can be inserted through the original entrance 21. When replacing the recording paper 27 or cleaning the recording head 3, this can be done with the cover 4 open, as shown in FIG.

As mentioned above, the vertical position of the front side part of the cover 4 is different during reception and transmission (it is located lower during reception than when transmitting). A microswitch or the like is provided opposite the lower end, and by detecting fluctuations in the vertical position of the front side surface, the facsimile machine can receive or transmit electrical signals in conjunction with the receiving or transmitting position of the cover, that is, the recording head. You can also switch.

As explained above, according to the present invention, the bamboo frame is comprised of a main body case that forms most of the bamboo body, and a cover that forms only a part of the upper part and is attached to the main body case so as to be openable and closable. At the same time, only the recording head is installed inside this cover with its recording section facing inward so that it is projected away from the inner surface of the cover, and other recording paper storage areas, feeding mechanisms, and document storage are installed. Since the optical mechanism and the supply mechanism are installed on the main body case side, the recording section of the recording head can be easily removed by simply removing the locking means and opening the cover. Since the head faces the operator, the recording head can be cleaned while attached to the machine, and recording paper can be replaced and loaded extremely easily.

In addition, since the recording head is installed so that it is forced to move away from the inner surface of the cover, not only can variations in the mechanical mounting structure caused by opening and closing the cover be automatically corrected, but also the recording paper Since the recording side is always ejected facing outward, troubles can be detected quickly. Moreover, since the cover only forms part of the upper part of the body and the recording head is attached, it is lightweight, making opening and closing operations extremely easy, and the mechanical strength of the cover is also small. Since the hinge for opening and closing the cover with respect to the main body case is also simple, it can be manufactured at low cost.
