No. 61121 is a diagram showing the configuration related to the interlocking means 60 and the roller 17 when the cover 29 is open.

With reference to FIGS. 2, 4 and 6, the recording means 18
When recording is to be performed on the recording paper 23 using the above method, the cover 29 is set in a closed state with respect to the housing 16, as shown in FIG.

As a result, the recording means 18 is brought into pressure contact with the roller 17, and the reading glass plate 21 is placed in a recording operation state separated from the roller 17. In this state, the recording paper 23 is guided by the recording paper guide member 25 and conveyed in the direction of arrow E1. When the recording paper 23 passes between the recording means 18 and the roller 17, recording is performed while being pressed against the roller 17 by the recording means 18.

On the other hand, when reading the original image of the original 30, the cover 29 is opened in the direction of arrow R4 with respect to the housing 16.
The state is as shown. by this.

The cover 29 can be used as a table for placing the original 30.

Further, as the cover 29 is angularly displaced in the direction of arrow R4 from the position shown in the fourth figure, the link 62 connected by the pin 66 to the rotation axis 67 of the cover 29 is driven in the direction of arrow B1. Along with this, the pin 65 to which one ends of the links 61 and 62 are tied in common moves the guide hole 63 to the arrow F1.
The displacement of the link 62 in the arrow B1 direction I\ is transmitted to the link 61. Since the other end of the link 61 is connected to the end member 47 by the pin 64,
A displacement of the link 61 in the direction of arrow B1 is converted into an angular displacement of the end member 47 in the direction of arrow C1.

In this way, the projections 49.51 of the actuating member 44.45 are spaced apart from the pressing means 33, and the projections 48.50 are moved away from the recording means 1.
8 is separated from the roller 17.

Further, for example, when the transmission of the original document 30 is completed and the cover 29 in the state shown in FIG. . Accordingly, the pin 65 to which one ends of the links 61 and 62 are commonly connected is guided through the guide hole 63 in the direction of arrow F2, and the displacement of the link 62 in the direction of arrow B2 is transmitted to the link 61. . The displacement of the link 61 in the direction of arrow B2 is converted into an angular displacement of the end members 46, 47 in the direction of arrow C2. In this way, the protrusion 49.51 of the actuating member 44.45 moves the pressing means 33 away from the roller 17,
The projections 48,50 are spaced apart from the recording means 18.

As explained above, the switching operation between the reading operating state and the recording operating state regarding the roller 17 can be performed by simply providing a simple interlocking means 60 between the cover 29 and the operating member 44.45. There is no need to provide a driving means for separately switching between the reading operation and the recording operation, and the configuration of the facsimile device 15 is simplified.

Further, in this embodiment, the reading operation or transmission of the original 30 is performed with the cover 29 opened in the direction of the arrow R4, using the cover 29 as a document mounting table. Therefore, in conjunction with the opening operation of the cover 29, the operating members 44 and 45 are necessarily switched for reading. This allows for example the actuating member 44
．． In a configuration in which an operating member or the like is attached to 45 and the switching operation is performed manually, an undesirable situation such as "forgetting to switch the operating member" is prevented from occurring.

As described in detail, according to the present invention, the opening/closing operation of the cover and the switching operation between the document reading operation state and the recording paper recording operation state are performed in conjunction with each other.

As a result, the switching operation can be performed simply by operating the cover, improving the operability of the facsimile machine. Further, such interlocking operation can be realized by simply adding a simple interlocking means to the force bar, and there is no need to provide a separate switching means, thus simplifying the structure of the facsimile machine and making it smaller.

Furthermore, the number of parts is also significantly reduced.
