Abstract

PURPOSE:To automatically sort an original and recording sheet by stopping a sheet discharge tray at a first position when the original is discharged and stopping the tray at a second position when the recording sheet is discharged. CONSTITUTION:When a stepping motor is driven and an output shaft 150a is rotated, a projecting part 153 is rotated so as to draw a circular arc with the output shaft 150a as a center and the inner wall of a through hole 152 is pushed by the projecting part 153. Then, a sheet discharge tray 107 is moved in a horizontal direction. When the sheet discharge tray 107 is positioned in left, in correspondence to the time of original sheet discharge, a home position sensor 151 detects a sheet discharge tray extending part 107a and is turned on. Accordingly, when the original is discharged, the sheet discharge tray is stopped at the first position and when the recording sheet is discharged, the tray is stopped at the second position. Then, both positions are slightly dislocated (in an extent enough for sorting). Thus, when an original size and a recording sheet size are same, both original and recording sheet are sorted while being dislocated only by a distance corresponding to the 'dislocation'.

(2) A document output tray for collecting sent documents.
A facsimile machine that can be moved in a direction perpendicular to the document ejection direction has been proposed (Japanese Patent Publication No. 55-11027).

This device separates originals in which a transmission error has occurred from originals that have been normally transmitted by changing the stopping position of the original discharge tray.

[Problem that the invention seeks to solve]

For facsimile machines that use a single tray as a collection tray for sent originals and a collection tray for received recording paper, paper is left unremoved from the tray. If you set "Send" and it will occur when you are dispatched on Monday, etc.),
Sent originals and received recording sheets are mixed together.

Since sorting them requires time and effort, there is a demand for automatically sorting them.

The present invention meets such demands.

[Means and effects for solving the problem] The present invention provides a facsimile machine that collects transmitted originals and received recording sheets in the same paper output tray, and the paper output tray is moved and placed in a predetermined position. A tray moving means for positioning; a determining means for determining whether the paper ejected to the tray is a transmitted original or a received recording paper; and a tray moving means for driving the tray moving means prior to paper ejection, A facsimile machine comprising: drive control means for positioning the paper ejection tray at a first position when the received recording paper is ejected, and positioning the paper ejection tray at a second position different from the first position when the received recording paper is ejected. be.

According to the above configuration, when the original is ejected, the paper ejection tray is stopped at the first position, and the original is ejected onto it.

On the other hand, when the recording paper is ejected, the paper ejection tray stops at the second position, and the recording paper is ejected onto it.

The first and second positions are slightly different (sufficient for sorting)
It is in a misaligned position. Therefore, for example, if the document size and the recording paper size are the same size, they will be sorted with a distance corresponding to the above-mentioned "shift".

*Description of Tray Movement Mechanism FIG. 2 is a partially cutaway perspective view showing the vicinity of the paper discharge tray 107, and FIG. 3 is a diagram illustrating the principle of movement of the tray 107.

As shown in the figure, the paper output tray 107 is installed so as to be movable in both directions from the upper right to the lower left of the figure, and the position of the paper output tray 107 can be changed depending on whether the original paper is ejected or the recording paper is ejected. By doing so, the document paper and the recording paper are sorted.

That is, one end of a long flat plate member 154 is fixed to the output shaft 150a of the stepping motor 150.
A protruding portion 153 is formed at the other end of the flat member 154 .

In addition, a through hole 152 is provided in the downward extending portion of the paper output tray 107 (the extending portion from the end closer to the main body) at the end of the IO7a (the left end in FIG. 3). It is formed into a substantially elongated shape so as to be stretchable.

Further, the protruding portion 153 is inserted into the through hole 152.

Therefore, when the stepping motor is driven to rotate the output shaft 150a, the protrusion 153 rotates to draw an arc (i, i' in the figure) centered on the output shaft 150a. Along with this, the inner wall of the through hole 152 is pushed by the protruding part 153, and as a result, the extension part 107a of the paper ejection tray, and therefore the paper ejection tray 107, moves in the left-right direction in FIG. will be moved to.

In addition, in FIG. 3, the position of the through hole 152 (
(corresponds when the paper ejection tray 107 is located at the lower left in FIG. 2) corresponds to the time when document paper is ejected. At this time, the home position sensor 151 detects the paper discharge tray extension part 107a and turns ONL, and the value of a position counter to be described later is set to "0".

On the other hand, the position of the through hole 152 drawn with a broken line (corresponding to when the paper output tray 107 is located at the upper right in FIG. 2) is as follows.
Corresponding to when the recording paper is ejected, the value of the position counter is “2”.
It is set to 4″.

In addition, in FIG. 2, 200 is an operation panel of this facsimile.

Explanation of this mock panel FIG. 4 is an explanatory diagram of the operation panel of the above embodiment device.

05, line connection section 306, expansion section 308, recording section 307
, an operation control section 309, and a comprehensive control section 310.

The reading unit 301 controls the operations of the image reading unit (document image scanning, exposure lamp dimming/lighting, image sensor driving, document conveyance, etc.).

The processing unit 302 performs predetermined signal processing (processing such as A/D conversion, naging, binarization, etc.) on the image signal (analog image signal) output from the reading unit 301.

The compression unit 303 stores the image data from the processing unit 302 or the image data from the expansion unit 308 (the image data is not sent to the called party at the time of image reading, but is temporarily stored in the memory 304, and is used at night when line usage fees are low. bit compression is applied to the data read out from the memory 304 and subjected to bit expansion at the time of transmission.

The memory 304 stores bit-compressed image data that is not immediately sent to the line.

The transmission control unit 305 uses the compression unit 303 or the memory 304
It controls the transmission of image data from the line to the line, or the storage of image data from the line connection unit 306 (data transmitted via the line) to the memory 304.

The line connection section 306 is an interface between the public telephone line and the present facsimile machine.

The expansion unit 308 bit-expands the image data (image data after bit compression) stored in the memory.

The recording unit 307 controls the operation of the image recording unit.

That is, as shown in FIG. 6, signals from the sensor group (such as the sensor 151 that detects the home position of the tray 107) and control signals from the general control unit 310 (such as /ft mode setting/cancellation commands) are Accordingly, various load groups of the image recording unit (recording paper feed/conveyance motor, paper feed clutch,
A laser device, a developing device, a fixing device, a charger, etc.) are driven to reproduce an image corresponding to the image data on a recording paper and discharge it onto a tray 107. Further, the stepping motor 150 is driven and controlled to control the movement of the tray 107.

The operation display unit 309 processes the manual input of keys on the operation panel shown in FIG. 4, and turns on and off the display elements on the operation panel.

The comprehensive control unit 310 controls the processing in each of the blocks while keeping the timing of each block.

1〉Main routine.

The CPU that controls the recording unit starts processing, for example, by receiving data from the calling side.

Initial settings are performed in step S1, and l
Starts an internal timer that defines the duration of the routine.

Note that the value of the internal timer is set in step Sl.

Thereafter, the image forming subroutine (s3; a routine that controls image forming using the laser device, charger, imaging device, photosensitive drum, etc.), and the paper feeding subroutine (s4: recording paper feed motor, transport motor, paper feed clutch) etc.), the fixing subroutine (S5: a routine that controls (distributes) the fixing device), and the shift tray subroutine (s6; a routine that controls the movement of the recording paper on the tray, which will be described later). ), and after expiring the internal timer in step S7, the process returns to step S2 and the process is repeated.

<2> Shift Tray Subroutine (S6) Next, the shift tray subroutine (S6) will be explained.

(1) In step 5101, it is determined whether a shift mode is set. If set, the shift mode indicator 216 is turned on (S I 03).

On the other hand, if it has not been set, the indicator 216 is turned off (5121) and the process returns to the main routine.

From step 5103, proceed to step 8105 and below.
Execute processing according to the state value.

The state is reset to "0" in the initial state.

When the start of document reading operation is detected (S I Q7;
If YES), the state is set to "1" (Si20) and the process returns to the main routine. As a result, the next time this subroutine is executed, a process for positioning the paper discharge tray 107 at the original collection position is executed (described later).

On the other hand, when the start of the image recording operation of the received data is detected (S l l l: YES> +t, maf, the value of the positive counter is determined. In addition, in the initial setting, the positive/con counter is , 0, and 24, which is different from any company.The position counter is a counter that corresponds to the number of steps of the stepping motor, and the position counter is set to a value that does not correspond to the number of steps of the stepping motor. Fig. 3 shows the case where the recording paper is at the reference position shown by the solid line @), and the case where the paper discharge tray 107 is at the recording paper collection position (Fig. 3; the broken line position).

Therefore, in the case of "position counter 0" (Sl

In addition, in the case of "position counter ≠ 0. ≠ 24" (S
If YES), the state is set to "2" and the process returns to the main routine. As a result, when this subroutine is executed next time, the process of returning the paper discharge tray 107 to the reference position is first executed (described later).

(iii>State=1 (5123; YES) If the state is "1", a process is executed to position the paper discharge tray 107 at the document collection position (FIG. 3; reference position shown by a solid line).

This shift tracer routine is executed as described above. In this embodiment, the paper ejection tray 107 is moved in a direction perpendicular to the paper ejection direction, but the present invention is not limited to this, and it may be moved in the paper ejection direction. It may be a rotational movement.

〔Effect of the invention〕

As described above, the present invention includes a tray moving means for moving the paper ejection tray and positioning it at a predetermined position, a determining means for determining whether the paper to be ejected is a sent document or a received recording paper, The apparatus includes a drive control means for positioning the paper ejection tray at a first position when the transmitted document is to be ejected, and for positioning the paper ejection tray at a second position different from the first position when the received recording paper is to be ejected. This is a facsimile machine that sorts sent originals and received recording sheets on the same paper ejection tray.

As described in the embodiments, according to the present invention, the paper ejection tray stops at the first position when a document is ejected, and stops at the second position when a recording paper is ejected.

The first and second positions are slightly different (sufficient for sorting)
Because of the shifted positions, the original and the recording paper are sorted with a distance corresponding to the above-mentioned "shift".

Therefore, even if paper cannot be removed from the tray for a certain period of time, the document and the recording paper are automatically sorted, which reduces the effort required to sort them.
