In FIG. 8, visual signal portions 915 are provided on both sides 914 in the width direction on the front side of the lid plate 91. As shown in FIG. The visual signal section 915 is for detecting the start and end of conveyance of the document tray 9, and as shown in FIG. 8, it consists of a colored section 915a and a non-colored section 915b. Note that the visual signal section 915 is
Hard coated to prevent wear.

(Operations of the Embodiment) Next, a method of using the facsimile according to the embodiment will be described.

First, when sending, as shown in Figure 1, the original 9
2 is placed on the document placement portion 900 of the substrate 90 by 4tffL. In this state, the cover plate 91 and the substrate 9o are aligned, and the latch 913 is secured to the stop portion 902, thereby holding the document 92. At this time, the original 92 comes into close contact with the back surface of the transparent portion 910 of the cover plate 91 due to the elastic force of the original placing portion 900.

With the original 92 held in the original tray 9 in this way,
As shown in FIG.
Enter II. Then, the reflective photointertabber 23 detects the visual signal portion 915 of the document tray 9 and issues a signal.

This signal starts driving the stepping motor 31. Therefore, the driving force of the stepping motor 31 is transmitted to the feed roller main body 300 via the gears V320 to 325 of the gear mechanism 32.
rotates. As a result, the document tray 9 is placed on the guide rail 1.
The tray storage section 11 is conveyed along the guide surface 120 of the tray storage section 2 . When the Dλ document tray 9 is conveyed to a certain extent, the reflective photo interrupter 23 moves the document tray 9
The visual field No. 18 975 on the other end side is detected, the stepping motor 31 is stopped, and the document tray 9 is stopped at the document scanning reading start position.

As described above, when the document tray 9 is guided along the guide surface 120 of the guide rail 12, as shown in FIG. The originals 1 to 9 are pressed against the guide surface 120 of the guide rail 12 by the member 34 . Therefore, there is an FJ! between the reading surface 21 of the reading head 2 and the cover plate 91 of the document tray 9! There is a gap.

As described above, since the document tray 9 is pressed against the guide surface 120 of the guide rail 12, the focal point of the reading head 2 matches the back surface of the transparent portion 910 of the cover plate 91, so that the document 9 in the document tray 9 matches the manuscript surface.

As described above, while the document tray 9 is stopped at the document scanning/reading gi1 starting position, the user operates the scanning/reading start switch. Then, the stepping motor 31 is driven, the feed roller main body 300 is reversed at a constant speed, and the document tray 9 is conveyed toward the insertion port 10 while being pressed against the guide surface 120 of the guide rail 12. At the same time, the reading head 2 starts reading the original 92 in the original tray 9. At this time, since the document tray 9 is in pressure contact with the guide surface 120 of the guide rail 12 as described above, the focus of the reading head 2 is on the cover plate 91.
The back surface of the transparent portion 910 of the document tray 9 corresponds to the document surface of the document 92 in the document tray 9. Note that the information read by the read head 2 is sent out to the telephone line.

When the reflective photo ink printer 23 detects the visual signal portion 915, the end of document scanning is detected.

Then, the stepping motor 31 is driven in a certain step, rotates the feed roller main body 300 by a certain amount, and stops the document tray 9 at a position completely separated from the feed roller main body 300. Considering the invasion, the original tray 9 is taken out from the insertion slot 10.

Next, the reception will be explained. When information is received from another facsimile machine over the telephone line, the stepping motor 70 is driven, and the information is transmitted to the platen roll 7 via gears 700 to 704, causing the platen roller 7 to rotate.

As a result, the thermal paper 80a of the thermal paper roll 80 set in the print paper roll holding section 8 is conveyed while being in contact with the thermal section 6a of the thermal head 6, and the received information is transferred to the thermal section 6a of the thermal head 6. The image is printed on the thermal paper 80a of the thermal paper roll 80. The printed thermal paper 80a is then discharged from the discharge port 16 by rotation of the platen roll 7.

By the way, when replacing paper, the Shimezu latch release lever 151 is manually moved in the six directions of the arrows against the spring 151a as shown in FIG.

Then, the latch 150 is pushed by the latch release bin 151 and swings through the shaft 150a, and the latch 150 is removed from the latch bin 100, so the swing bracket 15 is moved downward about the shaft 14 as shown in FIG. It can be swung. At this time, as shown in FIG. 4, the platen roll 7 and print paper roll holding section 8 are held by the swing bracket 15, so
and move downwards. In this case, as is clear from FIG. 5, the bottle 152 is guided along the guide groove 101. When the swing bracket 15 swings downward in this way, the paper exchange port S is opened and the print m paper roll holding section 8 is exposed, as shown in FIG. Replace the paper roll 80 as appropriate.

In addition, in case of replacement, the latch 150 and the latch bin 100 are locked by swinging the swing bracket 15 upward to restore its original state.

(Effects of Embodiment) As described above, in the printer device according to the present embodiment, the platen roll 7 and the print paper roll holding section 8 are held by the swinging bracket 15, and the swinging bracket 15 swings the printer. Since the platen roll 7 and print paper roll holder 8 swing downward integrally with the movable bracket 15, unlike the past, the platen roll 7 swings downward and the thermal paper roll 80 is inserted during paper exchange. The frontage of the mouth S becomes larger. Therefore, the work of replacing the thermal paper roll 80 with the print paper roll holding section 8 becomes easy.

Moreover, since the swing bracket 15 swings downward and does not swing upward, it is suitable for cases where there is no space for swinging the swing bracket 15 above the housing 1 when the housing 1 is attached.

In other words, there is no restriction on the presence or absence of space above the housing 1. Furthermore, since the swinging bracket 15 that forms the paper exchange port S in a swinging manner is located at the front part of the housing 1,
The thermal paper roll 80 can be replaced from the front side of the housing 1.

As described above, in this embodiment, when replacing the paper, considering that the thermal paper roll 80 can be replaced from the front of the housing 1 and that there is no restriction on the presence or absence of a space above the housing 1, the instrument panel, This is suitable for mounting on the front seat side of an automobile, where the facsimile must be mounted on the lower surface of a glove box, console, etc., and there is no space on the upper surface of the housing 1 to swing the swinging bracket 15.

Further, in the document tray 9 according to this embodiment, the transparent portion 91
Since the surface of the original 1190 on the side of the original 1190 held by the original tray 9 is used as the focus reference plane, it is easy to read the original surface of the original 1190 held on the original tray 9. Therefore, even if the focus rotation of the reading head 2 is narrow, the problem of mismatch between the focus of the reading head 2 and the original surface of the original 92 caused by rattling when transporting the original tray 9 can be improved. be able to. Further, in this embodiment, since the original tray 9 is used to hold and read the original 92, problems such as the original 192 being entangled or rubbed can be improved. Further, since the substrate 90 of the document tray 9 used in this embodiment has a rigidity of 1f1 degrees, it can also be used as a base for creating the document 92.

[Effects of the Invention] As explained above, in the printer device according to the present invention,
A platen roll and a print paper roll holding section are held by the swing bracket. Therefore, when swinging the swing bracket to open the paper exchange port, the platen roll swings together with the swing bracket, and the print paper roll holding section swings, exposing the print paper roll holding section. Therefore, the opening through which the thermal paper roll is inserted into the print paper roll holder becomes larger.

Therefore, it becomes easy to replace the thermal paper roll with the print paper roll holding section.

Moreover, when the platen roll swings downward, there may be no space on the upper surface side of the housing for swinging the swing bracket 1-. Therefore, it is necessary to install the printer device on the bottom side of the instrument panel, glove box, console, etc., and on the top side of the housing.
Suitable for mounting on car seats where there is no space to swing the swing bracket.

Further, in the printer device according to the present invention, since the thermal head is not attached to the swing bracket, the problem of disconnection of the lead wire of the thermal head can be solved.
