At this time, if the received document is already in the memory, printing is started with the standby switch 68 turned on. If there is no received document, place the original to be read on the original tray 14n and press a start button (not shown) on the operation panel 15 shown in FIG.
6n.

The standby switch 6 which operates in conjunction with the document tray 14n or the document stacker 16n of this embodiment.
By providing 8 in a facsimile machine, power consumption can be reduced, for example, by turning off an LCD (Liquid Crystal Display) while the machine is on standby. Further, since the received document is not printed and discharged without permission, the appearance when docked with another product is improved.

[0060]

As described above, according to the present invention, the facsimile apparatus is configured such that the document tray and the document stacker are housed in the housing of the apparatus body by inserting the facsimile apparatus through the opening. When the document is stored, the projections of the document tray and document stacker are eliminated, the installation area of the device is reduced, and the upper surface has no openings for document feeding and discharging and recording paper discharging. There is an effect that it is possible to place an object on the product and to dock another product.

According to the next invention, the facsimile apparatus is provided with a connecting portion for connecting the document tray and the document stacker in a hinge shape at the inner end of the housing of the document tray and the document stacker. If the opening angle can be changed, the document tray and the document stacker can be pulled out together and protrude from the opening. In addition, when storing, the opening angle of the document tray and the document stacker can be reduced and the document can be stored. This has the effect of reducing the dimension in the vertical direction.

Further, according to the next invention, when the facsimile apparatus has the angle variable unit in which the original tray and the original stacker are stored in the storage unit, the opening angle between the original tray and the original stacker is reduced, and When the document stacker is protruding out of the housing from the opening, if the opening angle is increased, the document tray or the document stacker can be used by pulling the document tray or the document stacker to a predetermined position. When the document tray and the document stacker are stored, the size of the storage section in the height direction can be reduced.

According to the next invention, if the facsimile apparatus is configured such that either the original tray or the original stacker holds the received paper after reception, the receiving paper stacker becomes unnecessary and the cost is reduced. effective.

Further, according to the next invention, the facsimile apparatus covers at least a part of the originals stacked on the original tray, and the original guide formed on the original tray holds the received paper after reception. This eliminates the need for a receiving paper stacker and has the effect of preventing the discharged receiving paper from mixing with the originals stacked on the original tray.

According to the next invention, in the facsimile apparatus, the movement preventing portion may prevent the original tray and the original stacker from moving from the state in which the original tray and the original stacker project outside the housing into the housing. There is an effect that the document tray and the document stacker drawn out of the housing can be prevented from returning to the inside of the housing due to vibration or the like.

According to the next invention, the facsimile apparatus has an opening cover provided on at least one of the document tray and the document stacker to close the opening in a state where the document tray and the document stacker are stored in the storage section. If you do
This has the effect of preventing dust and the like from entering the apparatus main body through the opening.

According to the next invention, when the facsimile apparatus is configured such that the original tray is pressed by the paper feed roller with the original tray protruding from the opening, the original tray is pulled out of the housing. Since the original tray is pressed against the paper feed roller, the set original can be reliably transported to the original reading unit, and the auxiliary roller is omitted because the original is pressed against the paper feed roller to apply a driving force. This has the effect of reducing costs.

According to the next invention, the facsimile apparatus is provided with a friction coefficient μ ₁ between the paper feed roller and the original, a paper feed roller.
When the friction coefficient between the pressing portion of the document tray pressed by the document tray and the document is μ ₂ , and the friction coefficient between the documents is μ ₃ , the relationship between the friction coefficients is μ ₁ > μ ₂ > μ ₃ , and the the coefficient of friction to minimize the mu _3, when so as to separate the plurality of originals stacked on the original tray, by pulling out the document tray from the housing, the document tray is pressed against the paper feed roller, one There is an effect that the separated documents can be reliably supplied to the document reading unit.

According to the next invention, when the facsimile apparatus is configured such that the electric drawer device drives the original tray and the original stacker stored in the storage section to project from the opening to the outside of the housing, the facsimile apparatus can be operated with one touch. There is an effect that the original tray and the original stacker can be used.

Further, according to the next invention, when the facsimile apparatus is set such that the original tray and the original stacker are protruded from the opening to a predetermined position, the switch is operated, and the apparatus main body can be used, the apparatus main body can be used. When not operating, there is an effect of reducing power consumed for standby for transmission or copying. Also, if the received document is stored in the memory, and the document tray and the document stacker are pulled out to a predetermined position, the switch is operated to print and discharge the received document. Since it disappears, it has the effect of improving the appearance when docked with other products.

Further, according to the next invention, when the facsimile apparatus is configured such that the document tray is formed of a wire, the cost can be reduced by making the document tray a wire, and the thickness of the document tray can be reduced. In addition, there is an effect that a thinner facsimile apparatus can be obtained.
