When loaded and fed from the manual feed port 28, the drive roller 23
The sheets are separated one by one by the separating member 31 in pressure contact with the transport rows 23a. 23b so as to be conveyed to the recording position.

[Manual feed tray and auxiliary tray]

Here, the manual feed tray 29 will be explained in detail. As shown in FIG. It is configured to guide the side edges of the recorded seams 7. Further, a fitting recess 29c is provided at the rotating tip of the tray 29.
This fitting concave portion 29c has a fitting convex portion 32 of the auxiliary tray 32.
It is constructed so that a can be fitted. HI, the auxiliary tray 32 can be connected to the manual tray 29 by fitting the fitting protrusion 32a of the auxiliary tray 32 into the fitting recess 29c of the manual tray 29, and the manual tray 32 can be connected to the manual tray 29 by removing the auxiliary tray 32. It is constructed so that it can be removed from 29.

Therefore, when the size of the recording sheet 17 to be placed on the manual feed tray 29 is long, the auxiliary tray 3 is placed on the manual feed tray 29.
2, the recording sheet opening 7 can be reliably placed on the tray and manual feeding can be performed. Furthermore, if the size of recording sheet number 7 is short, removing the manual feed tray 29 can eliminate wasted space for stacking recording sheets.Furthermore, when the manual feed tray 29 is not used, the auxiliary tray 32 can be removed. It can be removed and stored compactly, without creating wasted space in the device body or making the entire device larger.

Further, as shown in FIG. 1, on the lower surface of the recording sheet wandering tray 27 located above the manual feed tray 29, an oyster-shaped locking member 33 is provided protruding at an interval slightly wider than the width of the auxiliary tray 32. has been done. This locking member 33 constitutes a housing portion for the auxiliary tray 32, and the auxiliary tray 32 removed from the manual feed tray 29 is shown in FIGS. 2 and 3 from the tapered side (the left end side in FIG. 1). By inserting and locking the auxiliary tray 32 between the locking members 33, the auxiliary tray 32 can be accommodated on the lower surface of the recording sheet protruding tray 27.

By providing the accommodating portion for the auxiliary tray 32 as described above, the auxiliary tray 32 removed from the manual tray 29 does not get in the way and can be prevented from being lost. In general, the width and length of the ejection tray 27 are such that the ejection tray 27 can accommodate the recording sheets 17 loaded on the manual feed tray 29.
Since the paper is to be loaded again, the manual feed tray 29
By providing the storage section on the lower surface of the recording sheet ejection tray 27 located above the manual feed tray 29, the two can be stored so as to overlap, thereby saving space. It can be stored compactly. Further, there is no need to add a special space to the main body of the apparatus as an auxiliary tray accommodating section, and since the auxiliary tray accommodating section is accommodated near the manual feed tray 29, the storage location is easy to identify and handling is easy.

[Recorded size switch]

Further, as shown in FIG. 1, the manual feed tray 29 has a recording sheet to be manually fed on the inner side of the device and outside the fixed guide 29a, that is, outside the placement area of the recording sheet 17. A size switch 34 is provided for inputting the size of the sheet 17. In this embodiment, this switch 34 is used for ■A4 size, ■letter size (LTR), and ■
It is designed so that three types of legal size (LGL) can be input.

As a result, when the operator inputs the size of the recording sheet 17 loaded into the manual feed tray 29 using the size switch 34 and executes recording, the recording means B will perform recording according to the recording sheet size. A sensor for detecting the size of the recording sheet 17 and an extra space and display device for indicating the recording sheet size on the operation section are no longer required, and the number of parts is reduced, making the device more compact and reducing costs. It is possible to plan.

The size switch 34 is provided on the inner side of the manual feed tray 29 and on the back side of the tray opening/closing handle. 34 is located in a visual position near the operating position, so that the operator does not forget about the size manual force.

(Opening/closing cover) Furthermore, in the recording device, there is a recording car}
It is designed so that it can be exchanged. Therefore, in FIG. 2, the left side surface of the main body of the apparatus is configured as an open/close cover 35.

To explain this specifically, the opening/closing cover 35 is attached so as to be rotatable around a rotating bin 36, and the cover 3
A release lever 38 that rotates around a shaft 37 is attached to a predetermined position of 5 as shown in FIG. This release lever 38 serves as a release member for releasing the closed state of the opening/closing cover 35, and has a hook portion 38a formed at one end to engage with the chassis 39 of the device main body, and a hook portion 38a at the other end. A release button portion 38b is featured.

Torsional coil spring 4 attached to rotation shaft 37
When the hook portion 38a is locked to the chassis 39 due to the bias of 0, the opening/closing cover 35 is held in the closed state, and when the release button portion 38b is pulled up in the direction of the arrow e in FIG. The locked state of the portion 38a is released,
The opening/closing cover 35 is configured to be openable. The release button portion 38b is configured to be exposed through the through hole 35a of the opening/closing cover 35 so that it can be operated by an operator.

A manual tray 29, a drive roller 23a, a transfer roller 16, a fixing roller 25a, a pressure roller 25b, and discharge ports 26a and 26b are attached to the opening/closing cover 35, and as shown in FIG. When the cover 35 is opened, the members attached to the cover 35 are separated from the main body of the apparatus. Therefore, the opening/closing cover 3
When the cartridge 5 is opened, the recording cartridge 19 is exposed, and the cartridge 19 can be replaced.

[Relationship between the opening/closing cover and the recording cartridge] Here, to explain the relationship between the recording cartridge 19 and the opening/closing cover 35, the recording cartridge 19 has locking protrusions 19a on both sides as shown in FIGS. 2 and 4. is provided protrudingly, and the protruding strip 19a is provided in the cassette accommodating portion 41 of the main body of the device.
A locking/retaining groove 41a that can be slid into place is formed. Therefore, the recording cartridge 19 can be replaced with respect to the main body of the apparatus by opening the opening/closing cover 35, holding the handle 19b of the exposed recording cartridge l9, and inserting or removing the cartridge 19.

Further, the recording cartridge 19 is provided with a light shielding shutter 19c for protecting the photosensitive drum 1), which can be opened and closed about a shaft 19c+. This light-shielding shutter 19c opens automatically when the opening/closing cover 35 is closed, and the photosensitive drum 1
) and the transfer roller l6 are brought into pressure contact, and when the opening/closing cover 35 is opened, it automatically closes to shield the photosensitive drum 1) from light. The interlocking structure between the light shielding shutter 19c and the opening/closing cover 35 is constructed as shown in FIG. To explain this in the case of closing the opening/closing cover 35, a rod 43 is pivotally supported by a shaft 42 on the opening/closing cover 35.
At the tip of the rack 4 is biased by a tension spring 44.
5 is in contact. This rack 45 has pins 46a, 46
When the opening/closing cover 35 is closed and the rod 43 slides in the direction of the arrow f, the rack 45 slides in the direction of the arrow g.
The pin 19cz of the light-shielding shutter 19c mounted on the pinion arm 47a is lifted in the direction of arrow i by rotating the pinion 47 meshed with the pinion arm 47a in the direction of arrow h.
The light shielding shutter 19c is arranged to open. Also, when the opening/closing cover 35 is opened, the pin 19c is moved in the opposite direction to that described above.
2 is a pivot shaft 19c of the light shielding shutter 19c, which is lowered by the bias of a torsion coil spring 19c4 provided above, and the shutter 19c is closed.

[Relationship between the opening/closing cover and the recording sheet ejection tray] As mentioned above, the opening and closing of the light shielding shutter 19c is linked to the opening and closing of the opening/closing cover 35, so when taking out the recording cartridge 19, the opening/closing cover 35 is completely opened and the light shielding shutter 19 is opened and closed.
It is preferable to take out the container in a completely closed state. Therefore, in this embodiment, the release lever 38 of the opening/closing cover 35 cannot be operated unless the recording sheet ejection tray 27 attached to the opening/closing cover 35 is removed.

Specifically, as shown in FIG. 1, the recording sheet ejection tray 27 is inserted into the main body of the apparatus by engaging the locking protrusions 27a provided at both ends in the sheet width direction with the locking grooves 48 near the recording sheet ejection port. It is configured to be removable by attaching and releasing the lock, and furthermore, the ejection tray 27
A release prevention plate 27b is integrally provided on one side of the tray 27 to cover the through hole 35a through which the button portion 38b of the release lever 38 is exposed when the tray 27 is attached. Therefore, unless the recording sheet ejection tray 27 is removed, the release lever 3 cannot be operated and the opening/closing cover 35 cannot be opened.

When the opening/closing cover 35 is opened with the recording sheet ejection tray 27 still attached, the ejection tray 27 comes into contact with the installation floor.
The cover 35 may be damaged or the tray 27 may get in the way, making it impossible to open the opening/closing cover 35 completely, and at this time, the light-shielding shutter 19c may not be completely closed, resulting in the photosensitive drum 1) being exposed to light. In this embodiment, the opening/closing cover 38 cannot be opened unless the recording sheet ejection tray 27 is removed, so the above-mentioned inconvenience does not occur. In addition, since it is no longer necessary to forcefully remove the recording cartridge 19 with the opening/closing cover 35 half-open, the recording cartridge 19
There will be no inconvenience such as damage to the parts.

[Space for taking out the recording cartridge] Next, I will explain the space for taking out the recording cartridge 19 in the above-mentioned apparatus.As mentioned above, in this recording apparatus, the opening/closing cover 35 is opened and taken out. A document discharge tray 10 is provided above the cover 35. Therefore, the space below the document ejection tray 10 is used to take out the recording cartridge 19 as shown in FIG. 4, and a unique projection space is required to take out the recording cartridge 19 when installing the apparatus. do not. Therefore, it is possible to reduce the installation space of the device.

Drawer space of c-sent] Next, the drawer space of the cassette 20 storing the recording seam 7 will be explained.

As described above, the cassette 20 is removably housed in the lower part of the main body of the apparatus. As shown in FIG. 2, slide protrusions 20a are provided on both outer surfaces of the cassette container, and a cassette accommodating portion 49 is formed at the bottom of the device with an opening on the side where the document output tray 10 is attached.

A guide groove 49a into which the guide 0a can be fitted and slid is formed.

Therefore, the cassette 20 can be set by fitting the slide protrusion 20a into the guide groove 49a and pushing it in from the left side of FIG.
It can be taken out by holding the handle 20b shaped like 0 and pulling it out to the left in FIG.

As mentioned above, since the cassette 20 is taken out at the bottom where the document ejection tray 1O is provided as shown in FIG. This eliminates the need to provide additional space, making it possible to reduce the installation area of the device.

(Manual feeding and ejection space for recording sheet) In the apparatus of this embodiment, the projection space for ejecting the document is also effectively used as a space for manually feeding and ejecting the recording sheet 17.

That is, as shown in FIG. 2, a recording sheet ejection tray 27 is arranged above the manual feed tray 29, and an original ejection tray 10 is arranged above the protruding tray 27.

Therefore, the manual feed tray 29 and the recording sheet output tray 2
7 is located within the projection space of the document ejection tray 10, and the space below the document ejection tray 10 is effectively utilized. Therefore, as in the case described above, there is no waste of space, and the installation area of the device can be reduced.

[Arrangement of fixing means and document reading means] Furthermore, in the apparatus of this embodiment, as shown in FIG. The document reading means A is arranged above the fixing means. At this time, the light emitting member 8d of the reading means A,
A heat insulating means is provided to prevent damage to optical components such as the lens 8e and the photoelectric conversion element 81.

In the arrangement shown in FIG. 7, a recess 27c wider than the auxiliary tray 32 is formed on the surface of the recording sheet ejection tray 27, and the auxiliary tray 32 is accommodated in this recess 27c.
In the above-mentioned structure, it is preferable that the depth of the recess 27c is greater than the thickness of the auxiliary tray 32. Even if the auxiliary tray 32 is accommodated on the upper side of the recording sheet discharge tray 27 as described above, the same effects as in the embodiment described above can be obtained.

Further, in the above-described embodiment, a facsimile machine was illustrated, but it goes without saying that this can also be applied to other recording devices such as a copying machine.

<Effects of the Invention> As described above, in the present invention, the auxiliary tray is removably attached to the supply tray for supplying recording sheets to the recording means, and the accommodating portion for accommodating the auxiliary tray is provided.
When the auxiliary tray is not in use, by removing it from the supply tray and storing it in the tray storage section, the removed auxiliary tray does not get in the way and can also be prevented from being lost. Further, by providing the tray storage section on the recording sheet discharge tray, it becomes possible to store the auxiliary tray in a stacked manner on the protruding tray, and there is no need to add a special space to the main body of the apparatus as an auxiliary tray storage space. Furthermore, since an auxiliary tray is housed at the ejection tray position, handling is also facilitated.
