Abstract

PURPOSE:To prevent paper jamming generated by turning a recording travelling path to a steep U-shape at the time of miniaturizing an equipment by linearly constituting a recording paper travelling path and arranging a recording head so as to perform printing downwards. CONSTITUTION:When recording paper 16 is drawn out from a paper feeding cassette 14 at the lowest part of the main body of the equipment, a separating pawl provided on the side of the main body presses down both tip parts of the recording paper at the top, a roller 17 rotates at the center tip part of the recording paper 16 and thus, the recording paper is separated one by one and drawn out to a printing point 18. Since the recording head is arranged so as to let a printing surface face downwards at the printing point 18, the recording paper travelling path becomes almost linear. An optical system unit 10 is arranged at a position where it is pushed out to the front of the equipment so as to miniaturize the equipment. An original 22 mounted on an original platen 2 is introduced one by one to an original travelling path B by an introducing roller 23 and the paper is fed through the roller 25 to an original read point 26 by the roller 24. The original 22 is read by an optical system 27 and is ejected to an ejecting tray 29 by the roller 28.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus which is downsized and is designed to be user-friendly.

[0002]

2. Description of the Related Art In recent years, facsimile machines using general plain paper as recording paper have become widespread. Most of the facsimile machines of this type have a laser printer as a recording unit.

However, since a laser printer is generally expensive, an inkjet printer is used as a recording unit in a low-priced facsimile machine for plain paper.

Generally, in this type of ink jet type facsimile machine, the paper feed cassette is arranged in the lower part of the device, and the recording paper is arranged above the paper feed cassette along a U-shaped curved recording paper running path. It is configured to be conveyed to the recording unit and discharged onto a discharge tray on the side of the apparatus by a discharge roller after the printing operation is completed.

[0005]

However, in such a conventional structure, since the traveling path of the recording paper is curved in a U shape, the recording paper is bent in the process up to recording, and In the case of weak paper or the like, paper jam may occur.

Further, since the running path of the recording paper is U-shaped, it has been an obstacle to downsizing the apparatus. That is, the recording paper is initially in the paper feed cassette at the lower part of the apparatus, and when it is next fed to the transport guide, it goes from bottom to top,
At the time of recording, it was recorded in the recording section in the center of the device. For downsizing, if the conveyance guide is shortened and the height of the entire device is lowered, the size can be reduced, but the U-shaped traveling path becomes abruptly rotated, and paper jams are more likely to occur. It was

Further, since the ink jet printer has a slower recording speed than other recording methods, the image data transmitted from the general communication line is temporarily stored in the memory and the recording operation is performed for each unit of a plurality of lines. Therefore, a general user needs an image data memory having a normal capacity, whereas a user who constantly receives a large amount of image data needs an image data memory having a relatively large capacity.

The present invention is intended to solve the above-mentioned problems.
A facsimile machine that realizes a running path that is less likely to cause paper jams while downsizing the entire apparatus, and secondly, can be used by both general users and users who constantly receive large amounts of image data. It is provided.

Thirdly, the present invention is related to the above-mentioned problem, and it is an object of the present invention to prevent the external memory socket from being destroyed by the force generated when the external memory is inserted, thereby preventing the writing failure to the external memory. And

The present invention relates to the above-mentioned problem of paper jam prevention, and fourthly, it is an object of the present invention to suppress the occurrence of paper jam caused by the setting of the recording paper in the paper feeding cassette when the recording paper is fed. It is a thing. Fifthly, the recording paper is misaligned from the set position during the recording operation, and a paper feed error occurs.
The purpose is to prevent paper jams.

Further, since the present invention is an ink jet type facsimile apparatus, it is necessary to replace the ink jet cartridge at the end of the recording life. It does not matter where the insertion port for replacing the ink jet cartridge is provided, but in a miniaturized facsimile device, the document table constituting the upper part of the device is usually opened and closed to replace the ink jet cartridge in the device. It is composed. Further, on the document table, a lid for the upper surface of the device which also serves as a document auxiliary tray is configured to be rotatable. The upper surface lid is in the closed position when the original is not read and functions as an upper surface lid of the apparatus. When the original is read, the upper surface lid rotates and falls to the rear of the apparatus to function as an original auxiliary tray. When replacing the ink jet cartridge, if the original table is opened while the original auxiliary tray is tilted backward, the original auxiliary tray is further rotated rearward in conjunction with the rotation operation of the original table. There is a risk of colliding with the recording paper discharge tray located and being damaged. There is no problem if the original document tray is returned to the closed position as the upper surface lid and then the original table is opened for cartridge replacement, but such an operation is troublesome for the user. Also, the user may forget to return the original auxiliary tray to its original position due to carelessness.

In order to solve the above problems, a sixth aspect of the present invention is to reduce the size of the apparatus and to make it easy for the user to use. When the ink jet cartridge is replaced, the original table serving as a lid for the cartridge insertion opening is used as an original auxiliary tray. SUMMARY OF THE INVENTION An object of the present invention is to easily realize a facsimile device which cannot be accidentally opened while being tilted backward.

[0013]

In order to solve the above-mentioned problems, the present invention firstly arranges a paper feed cassette for setting recording paper in the lower part of the apparatus, and feeds the recording paper to the bottom surface of the apparatus. It is configured such that it is transported while being regulated in a substantially straight line by a transport guide provided in parallel, and printing is performed from top to bottom by a printing unit having a printing surface arranged below.

Secondly, a slot for inserting an external memory for accumulating the received image data is provided on the side surface of the apparatus, and a rotatable panel cover formed on the front surface of the apparatus also serves as a lid for covering the slot in the closed position. It is equipped with a configuration.

Thirdly, a socket for connecting with an external memory for accumulating the received image data is arranged on the main board, and the shape of the tip of the guide guide for restricting the insertion of the external memory into the socket is changed to the main board. The side edges of the above are sandwiched from above and below, and the guide guide is fixed to the main base.

Fourthly, the recording paper guides for controlling both side surfaces of the recording paper set in the paper feed cassette are provided with insertion pins at wide and narrow intervals, respectively, and the bottom of the paper feed cassette is provided at wide and wide spaces at different intervals. A set of insertion holes is provided, and the user sets the recording paper guide by left-right replacement according to a desired size width.

Fifthly, a rear side of the paper feed cassette is used as an auxiliary member that can be inserted and removed, and a structure is provided in which the rear end of the recording paper set in the paper feed cassette is pushed and held.

Sixth, a document table on which documents are stacked is rotatably held above the apparatus, and the document table functions as a document auxiliary tray for assisting the document table in the open position and the upper surface of the apparatus in the closed position. An auxiliary document table functioning as a cover for covering the document table is rotatably provided, and the document table is restricted from being opened when the auxiliary document table is in the open position, and the document table can be opened when the auxiliary document table is in the closed position. Be prepared.

[0019]

According to the present invention, when the apparatus is miniaturized, firstly, when the apparatus is miniaturized, the traveling path of the recording paper is made linear and the print head of the recording portion is arranged downward, so that the paper feeding cassette is arranged. The recording paper fed from is fed in a substantially straight line from being fed by the feeding roller to being ejected to the recording paper tray by the ejection roller via the recording unit. This reduces the risk of paper jams.

Secondly, when a large amount of data is received, the capacity of the image data memory of the apparatus main body is set to the normal capacity, but the external memory is inserted, so that the image data memory capacity of the apparatus main body is not changed. It can receive and record a large amount of image data. In this case, the lid for the slot for inserting the external memory is not provided specially, and the panel cover of the device is also used as the lid for the slot, so that the panel cover is closed and the slot is not exposed from the outside when the external memory is not used. ,
When using, open the panel cover to expose the slot and insert the external memory. As a result, the user is not given the impression that the facsimile machine is dedicated to the external memory.

Thirdly, when the external memory is inserted into the apparatus, even if the external memory is inserted vigorously, the shape of the guide guide for introducing the external memory into the socket is brought into contact with the side edge of the main base so that the external memory can be protected. The pushing force is transmitted to the guide guide first, and then the pushing force pushes the side edge of the main base, so that it is not directly applied to the socket. As a result, it is possible to eliminate the problem that the socket is broken or the contact between the socket and the main board is deteriorated due to the force of inserting the external memory.

Fourthly, when the recording paper is set in the paper feed cassette, the recording paper guide regulates the side edge of the recording paper.
In order to realize the size width with this recording paper guide, it is possible to surely realize two kinds of size widths at predetermined positions by turning over the front end and the rear end instead of performing the parallel movement. Will not be set incorrectly. As a result, it is possible to reduce the occurrence of paper jam due to a setting error of the recording paper.

Fifthly, when the recording paper set in the course of the recording operation is displaced later, the rear side of the paper feeding cassette is made an auxiliary member which can be inserted / removed so that the auxiliary member is simply pushed from the rear side. The trailing edge of the recording paper will be trimmed. With this, when confirming whether the recording paper is complete,
It is possible to omit the complicated operation of the user who takes out the paper cassette one by one before starting the recording operation.

Sixth, when the upper lid constituting the upper part of the apparatus is also used as the original tray and the original table formed under the upper lid is the lid for the recording cartridge exchange port, the upper lid is used. When the tray is opened and used as a document tray, the end of the upper surface portion pushes the document table by its own weight, so that the opening and closing of the document table is locked, and the document table is fixed in the closed position. Further, when the upper lid is closed, the document table is opened together with the upper lid, and the recording cartridge can be replaced. As a result, even if a special lock mechanism is not provided, it is impossible to open the document table when the upper surface lid is open and becomes the document tray.

It should be noted that the recording head is installed downward at the recording head printing point 18. 21 is an ink cartridge,
It can be replaced by opening and closing the document table 2.

An auxiliary document table 3 is formed on the upper surface of the apparatus, and it is rotatably held at the end of the document table 2. When not in use, the auxiliary document table is in the closed position and covers the upper surface of the apparatus, and is integrated with the apparatus body as a lid for the apparatus upper surface. Further, during use, the auxiliary document table 3 can be rotated rearward from the closed position to be used as a document auxiliary tray. Below the auxiliary document table 3 is the document table 2, which also serves as a lid for covering an insertion opening for replacing the ink jet cartridge.

A document discharge tray 29 formed in front of the apparatus is also the same as the auxiliary document table 3. That is, the document discharge tray 29 is rotatably held by the paper feed cassette cover 15 which constitutes the paper feed cassette unit 13, and is in the closed position when not in use and is in the closed position.
3 can be used as a document tray by covering a part of the upper surface of the sheet 3 and being integrated with the sheet feeding cassette 14 and by rotating it from the closed position to the front to extend the length first.

Reference numeral 30 is an operation panel for the user to perform a transmission operation, 31 is an IC memory card as an external memory, and 32 is a main board of this apparatus. FIG. 4 is a partially enlarged perspective view showing a slot for inserting an external memory, which is diagonally forward of the facsimile apparatus of this embodiment, and a peripheral region thereof in an enlarged manner.

In FIG. 4, 33 is the IC memory card 3.
1 is a slot for inserting 1 and is provided in the middle position of the device.

The operation of the entire facsimile apparatus of the present invention will be described below with reference to FIGS. 1 to 4.

First, in the recording operation, when the recording paper 16 is fed from the paper feed cassette 14 forming the lowest portion of the apparatus main body, the separation claws provided on the apparatus main body side are provided at both ends of the leading end of the recording paper at the top. By pressing and receiving and feeding roller 17 rotates at the center of the front end of recording paper 16, the recording paper is separated one by one and fed to recording head print point 18.

At the recording head printing point 18, the recording head is arranged so that the printing surface faces downward as described above, so that the recording paper running path A can be realized in a substantially linear shape.

However, when the recording head is arranged in the upright position, the recording control unit for driving the recording head is inevitably arranged in the vertical position, and the size reduction of the entire apparatus is restricted by the height of the recording unit. . In view of this, the present apparatus has a configuration in which the transmission optical system unit 10 is arranged at the position pushed out to the front of the apparatus in order to make the apparatus as small as possible within the constraints of miniaturization due to the height of the recording unit.

When the printing operation of the recording paper is completed, the recording paper is discharged to the recording paper discharge tray 20 by the recording paper discharge roller 19.

Further, in the case of the ink jet type facsimile apparatus, since the general recording speed is slow, the image data printed on the recording paper is temporarily stored in the memory. Since a large amount of image data that exceeds the capacity of this memory may be received in some cases, the IC memory card 31 can be added as an external memory in this embodiment. The slot 33 of the IC memory card 31 is provided in front of the side surface of the device so that it can be easily inserted by the user. The main board 32, to which the socket into which the IC memory card 31 is inserted, is connected, is parallel to the position of the socket 33 and is located at an intermediate position inside the apparatus, that is, the paper feed cassette 14 and the optical system 27.
It is located in the position between and. This arrangement position is because the probability of occurrence of connection failure is reduced when the main board 32 and the socket are directly connected rather than when the main board 32 and the socket are indirectly connected by a connector. That is, since the socket to which the IC memory card 31 is connected is directly provided on the main board 32, the main board 3
Since 2 is provided in parallel with the position of the slot 33,
The arrangement position of the main board 32 is set to the middle position inside the apparatus.

Next, in the reading operation, the auxiliary document table 3 rotatably held on the document table 2 is rotated toward the rear of the apparatus, and the auxiliary document table 3 is used as a document auxiliary tray. The document 22 stacked on the paper is supported secondarily. The originals 22 stacked on the original table 2 are introduced one by one into the original traveling path B by the introduction roller 23, and are fed to the original reading point 26 by the transmission paper feeding roller 24 via the driving roller 25. The original 22 is optically read by the optical system 27 at the original reading point 26 and is ejected to the original ejection tray 29 by the ejection roller 28.

The constituent parts of the facsimile apparatus of the present invention will be described below in sequence. First, the components of the IC memory card 31 will be described with reference to FIGS.

As described above, the ink jet recording method has a slower recording speed than the other recording methods.
The image data is once stored in the image data memory and recorded. Therefore, if a large amount of image data is received and the amount of received data written in the image data memory exceeds the amount of data transferred to the recording unit for the recording process, the image data memory will no longer store the received image data. Can not be
Reception error may occur. However, in an ordinary inkjet type facsimile machine, there is no problem because the capacity of the image data memory is set so that it can be used in general.

However, some users always receive a large amount of image data, and the memory having the above capacity is not sufficient for these users. However, if the memory capacity is increased to accommodate a large number of receiving users, the cost of the entire apparatus also increases, so it is not a good idea considering general users.

Therefore, in the facsimile apparatus of the present embodiment, the image data memory of the apparatus main body is set to a normal capacity and the IC memory card 31 is used, so that not only general users but also a large amount of data can be received. We made it possible for users who use it to fully use it. When the IC memory card 31 is inserted in this way, I
A slot 33 which is an insertion port of the C memory card 31 is required. If foreign matter such as dust enters the inside of the apparatus through the slot 33, it causes a malfunction, so that a lid structure for covering the slot 33 when the external memory is not used is also required.

However, if a lid dedicated to the slot 33 is provided, it may give the impression that it is a dedicated model for a user who uses the IC memory card 31.

Therefore, in order not to give the impression that the IC memory card 31 is a dedicated model, the panel cover 11 is also used as a lid for the slot 33 so that the panel cover 11 is closed when the panel cover 11 is closed. The cover serves as a lid for the slot so that the slot cannot be seen from the outside, and when the IC memory card 31 is inserted, the panel cover 11 is opened and the slot 33 appears. In this way, the panel cover 1 that does not open frequently
Since 1 is used as the lid of the slot 33, it is possible to realize a facsimile apparatus in which the IC memory card 31 is inserted without giving a feeling of strangeness to a general user.

Next, the relationship between the IC memory card 31 and the main board 32 will be described in more detail with reference to FIGS.

FIG. 5 is a view showing a state (a) in which the IC memory card 31 is inserted into the socket attached to the main board 32 and a state (b) in which the IC memory card 31 is attached, and FIG. 6 is a side view showing the state shown in FIG. It is a state transition diagram seen from.

5 to 6, reference numeral 34 is a socket which is connected to the IC memory card 31 to write and read image data to and from the IC memory card 31. 35 is I
A guide guide 35 for guiding the C memory card 31 to the socket 34. 5A is shown in FIG. 5A and FIG. 5B is shown in FIG.
Represents the corresponding states corresponding to (b), and (c)
Shows the state where the insertion of the IC memory card 31 is completed.

The insertion operation of the IC memory card 31 having the above structure will be described below. IC memory card 3
1 is inserted into the inside of the device through a slot 33 provided on the side surface of the device. The main board 32 is in the slot 3 inside the device.
It is arranged at the same height as 3 and the socket 34 connected to the IC memory card 31 is incorporated therein. When connected to the socket 34, the IC memory card 31 will function as a memory of the apparatus body. Note that I
As shown in FIGS. 5 (a) and 5 (b), the C memory card 31 is provided with a guide guide 35 in a socket 34 on the main board 32.
Connected through.

If the IC memory card 31 is inserted from the slot 33 with vigorous insertion, a strong impact is applied to the socket 34, which may damage the socket 34 or weaken the contact between the socket 34 and the main board 32. there is a possibility.

Therefore, in the present embodiment, the shape of the guide guide 35 is such that the main base 32 is sandwiched from above and below as shown in FIG. 6 (c). In this way, when the tip of the guide guide 35 is shaped so as to sandwich the main board 32 from above and below,
As shown in (a) and (b), since the guide guide 35 is in contact with the side surface of the main board 32, the force generated when the IC memory card 31 is inserted is not directly applied to the socket 34. That is, first, the inserting force is transmitted from the IC memory card 31 to the guide guide 35, and then the force transmitted to the guide guide 35 becomes a force for pushing the side edge of the main base 32 by the tip of the guide guide 35, and finally It will be transmitted to the side of the main base 32. This gives I
The force generated when the C memory card 31 is inserted does not damage the socket 34 and the contact between the socket 34 and the main board 32 does not deteriorate.

Next, the paper feed mechanism in this embodiment will be described with reference to FIGS. FIG. 7 is a partially cutaway perspective view showing the sheet feeding mechanism and the periphery of the recording unit in the present embodiment.

In FIG. 7, reference numeral 36 is a separation claw for separating and feeding the recording papers 16 set in the paper feed cassette 14 one by one. The separation pawl 36 is provided not on the paper feed cassette side but on the recording device side. 37
Is a recording head printing unit for printing the recording paper 16 fed to the recording head printing point 18. 38 is the paper feed cassette 14
2 is a recording paper guide that regulates the sides of the recording paper 16 that is set to. Reference numeral 39 denotes an auxiliary member that regulates the rear end of the recording paper 16, which is called a recording paper guide and constitutes the rear side of the paper feed cassette 14.

As described above, the paper feed cassette 14
Forms the bottom surface of the main body of the device, which makes it possible to reduce the size of the device by removing the bottom part of the outer frame of the paper feed cassette storage section, compared to the case where the housing of the device is the bottom surface. Has been realized. Recording paper 1 set in the paper feed cassette 14
A side edge of the sheet feed source 6 is regulated by a recording sheet guide 38 in the sheet feeding cassette 14, and a rear edge thereof is regulated by a recording sheet catch 39 that constitutes a rear edge of the sheet feeding cassette 14. A paper feed cassette cover 15 is provided on the front side of the upper part of the paper feed cassette 14, and a document discharge tray 29 is rotatably held.

FIG. 8 shows the main body side of the paper feed mechanism, and FIG. 9 shows the paper feed cassette side of the paper feed mechanism.

In FIG. 8, 39 is a plate for movably holding the separation claw 36, 40 is a boss provided on the plate 39, and this boss has a groove of a recording paper guide set in the paper feeding cassette. Be fitted into.

In FIG. 9, reference numerals 41 are grooves respectively provided at the front and rear ends of the recording paper guide 38, which are fan-shaped. The boss 39 shown in FIG. 8 is fitted into the groove 41. Since the groove 41 has a fan-shaped open shape, the groove 41 widely catches the boss 39 at the beginning of insertion into the groove 41 even if the boss 39 is in an indefinite position.
As the insertion of the boss 39 into the groove 41 progresses, the position of the boss 39 is gradually regulated.
The position of is completely regulated. In this way, the groove 41 of the recording paper guide 38 has a fan-shaped shape that opens to the end in order to regulate the separation 36 of the recording paper provided on the recording unit side according to the size width of the recording paper. ing. Also, the recording paper guide 3
The groove 41 is provided at both the front end and the rear end in FIG. 8 in order to use the respective recording paper guides 38 by turning them upside down according to a plurality of recording paper sizes. That is, each recording paper guide 38 is provided with a pin 42 for setting in the paper feed cassette 14. The position where the pin 42 is provided is the recording paper guide 38A.
Unlike B and B, the recording paper guide 38A is provided inside at a narrow interval, and the recording paper guide 38B is provided outside at a wide interval. Holes 43 corresponding to the pins 42 of the recording paper guide 38 are also provided on the left and right sides of the set surface of the paper feed cassette 14.
Each set is provided with a narrow spacing and a wide spacing. Regarding the left and right holes 43, the left side 43B is nmm from the center even when the right side 43A is away from the center (see FIG. 9).
3 mm), and they are provided with a large offset. In (a), A4 size recording paper size is realized, and
In (b), a B5 size recording paper size is realized.

In this way, the recording paper guide 38 is simply
Is less likely to cause a harmful effect due to the user setting the recording paper guide 38 without checking the insertion position of the recording paper guide 38 due to habituation, as compared with the case where the recording paper guide 38 is moved in parallel to adjust the recording paper width. Become. That is, if the recording paper width is adjusted by narrowing or widening the intervals of the recording paper guides, the insertion holes on the paper feed cassette 14 are also laid parallel to each other for each recording paper size, so that the user may get used to it. When the recording paper guide is set by the above, although the recording paper guide A is actually set in the A4 hole and the recording paper guide B is set in the B5 hole, the user does not notice the mistake and the user sets the recording paper guide in the B5 size. I sometimes assume that I have set it. At that time, if the recording paper 16 is set in the paper feeding cassette 14 as it is and the recording paper 16 is started, the recording paper 16
Since the regulation on the side of is not accurate, the recording paper 16 is bent and fed, which causes a paper feed error and causes a paper jam. Furthermore, when a large number of insertion holes are provided in the paper feed cassette 14 in order to realize a large number of recording paper sizes, the above-mentioned harmful effect is more likely to occur. Originally, the configuration for moving the recording paper guide 38 to determine the recording paper size is
The paper feed cassette 14 is prepared for each recording paper size, and the complexity of having to replace the paper feed cassette 14 for each recording of another size is solved. The guide 38 will be useless.

Therefore, the present apparatus is configured such that the user can realize another recording paper size for the first time by turning the recording paper guide 38 upside down and setting it in the paper feeding cassette 14. As a result, only two kinds of recording paper sizes can be realized, but these two kinds of recording paper sizes can be surely realized, and the possibility of paper jam due to a paper feed error is reduced.

Further, as shown in FIG. 9, the paper feed cassette 14 is provided with a recording paper catch 39 for pressing the rear end of the recording paper in addition to the above-mentioned recording paper guide 38. Figure 10
The state before and after the insertion of the recording paper catch 39 is shown.

In the present embodiment, although not shown, the leading end of the recording paper 16 set in the paper feed cassette 14 is raised to the position of the paper feed roller 17 when the recording operation is started. When the recording operation is completed, it returns to the original position again. The bottom surface of the paper feed cassette 14 is configured to convey the recording paper 16 in a substantially straight line to the recording portion, and thus has a gentle angle that gradually increases from the bottom to the top. In this way, when the leading edge of the recording paper moves up and down for each recording operation,
Since the bottom surface of the paper feed cassette 14 in which the recording paper 16 is set is slanted backward, the vibration causes the recording paper to gradually shift later as shown in FIGS. 10A to 10B. . Once the recording paper 16 is set in the paper feed cassette 14, it is troublesome for the user to check whether or not the recording paper 16 is displaced from the outside for each recording operation. . That is, this is an operation in which the paper feed cassette 14 is pulled out from the apparatus main body for each recording operation, the cover 14 is removed, the deviation of the recording paper is confirmed, and the paper feed cassette 14 is returned to the apparatus main body again. Therefore, in many cases, the recording operation is started without the recording papers 16 being aligned. If the recording operation is started with the recording paper 16 being misaligned afterwards, the recording paper 16 does not reach the paper feed roller 17 and is not fed, or even if the paper is fed, it is not normal paper feed and paper jam occurs. It was causing it.

Therefore, an auxiliary member, that is, the recording paper catch 39, which can be inserted and removed from the rear side of the paper feed cassette 14, is used.
As a result, even if each recording operation is performed later, FIG.
From (d) to (d), the rear end of the recording paper 16 can be aligned by simply pressing the rear end of the recording paper from the rear, and this is not a troublesome operation for the user. Further, by removing the recording paper catch 39, the recording paper 16 can be replenished without pulling out the paper feed cassette 14 itself, so that the replenishment work of the recording paper 16 becomes easy.

Next, the mechanism relating to the auxiliary document tray and the document table in this embodiment will be described with reference to FIGS. 11 to 12.

FIG. 11 is a partially enlarged perspective view showing the connection relationship between the auxiliary document table, the document table and the apparatus main body. FIG. 11A shows the auxiliary document table, the document table and the apparatus main body in a disassembled state. ing. Further, (b) shows a state in which the auxiliary platen, the platen, and the apparatus main body are combined.

FIG. 12 is a state transition diagram showing an open state or a closed state of the auxiliary document table and the document table.

In FIG. 11, 3 is an auxiliary document table,
It has a groove with a pin serving as a fulcrum of rotation. Reference numeral 2 denotes a document table, which has holes for inserting pins of the auxiliary document table 3 and the document table 2
Has a pin serving as a fulcrum of rotation. Reference numeral 9 denotes a side cover, which has a hole into which a pin of the document table 2 is inserted and a groove which meshes with a convex portion of the auxiliary document table 3, and is provided with a holding table 44 for holding the rotation of the document table 2. .

The operation of the mechanism relating to the auxiliary document tray and the document table of the present embodiment configured as described above will be described below.

First, when the apparatus is not used or the non-reading operation is performed, as shown in FIG.
Is also in the closed position. When the document 22 is transmitted, the auxiliary document table 3 is rotated backward around the fulcrum as shown in FIG. 12B, and is tilted backward as shown in FIG. 12C to open the document stacking unit. FIG. 1 shows the state. When the auxiliary document table 3 falls backward as shown in FIG. 12C, the auxiliary document table 3
Serves as a document feed tray, which assists in reliable feeding of even large documents. Also,
The original table 2 is also rotatably held in the apparatus main body in order to replace the ink jet cartridge inside the apparatus. That is, since this apparatus uses the ink jet recording method, if ink is consumed, it will be necessary to replenish ink. Normally, this ink supply is performed by replacing the ink cartridge, but in this embodiment, this replacement port is provided in the upper part of the apparatus casing and the original table 2 is used as a cover for the replacement port of the ink jet cartridge. Therefore, the original table 2 can be opened even when the auxiliary original table 3 is open. In this case, the auxiliary document table 3 is the document table 2
As the sheet is opened, the sheet further falls backward and collides with the recording sheet discharge tray 20 formed at the rear portion of the apparatus, which may cause damage. This can be solved by providing the document table 2 with a lock mechanism, but the cost becomes high.

Therefore, in the present embodiment, when the auxiliary document table 3 is at the open position, the concave portion of the rear portion of the auxiliary document table 3 meshes with the concave portion or the convex portion of the holding table 44 of the apparatus main body to open the auxiliary document table 3. The upper limit of the angle is regulated. That is, FIG.
When the original table 2 is opened in the state of 2 (c), a force is applied to the auxiliary original table 2 provided with a rotation fulcrum on the original table 2 to open it further rearward. However, since the upper limit of the opening angle of the auxiliary document table 3 is restricted by the holding table 44, the auxiliary document table 3 is not rotated further rearward. Therefore, the rotation of the document table 2 is also regulated because the rotation angle of the auxiliary document table 3 is regulated. Here, the relationship between the concave portion of the auxiliary document table 3 and the convex portion of the holding table 44 is set so that the document table 2 is not rotated at the upper limit of the rotation angle of the auxiliary document table 3. As a result, the document table 2
Auxiliary manuscript table 3 without attaching a special lock mechanism to
It is possible to prevent the document table 2 from being opened only by setting the to the open position.

FIG. 13 is a diagram showing the state of FIG. 12 (c) in detail. That is, when the document table 2 is opened, the document table 2 is rotated about the fulcrum B. At this time, since the auxiliary document table 3 is also held on the document table, the auxiliary document table 3 tries to rotate backward together. However, the projection D is provided on the holding unit 44, and the tab F of the auxiliary document table 3 approaches the projection D as the auxiliary document table 3 shifts rearward. When the claw F and the projection D collide with each other, the auxiliary document table 3 cannot rotate further backward, and the rotation of the document table 2 is restricted.

When the auxiliary document table 3 is in the closed position, the document table 2 is unlocked, and the document table 2 can be rotated as shown in FIG. 12 (d). Therefore, when it is desired to replace the ink jet cartridge, the auxiliary document table 3 and the document table 2 may be integrally opened by closing the auxiliary document table 3. As a result, since the original platen 2 cannot be opened unless the auxiliary original platen 3 is closed, there is no risk of damaging the auxiliary original platen 3 or the recording paper discharge tray 20 as the original document tray when replacing the cartridge. Further, the document table 2 can be locked with a simple mechanism without providing a special mechanism.

As described above, the facsimile apparatus according to the present embodiment solves various problems that occur when the apparatus is downsized, realizes a traveling path in which paper jams are less likely to occur, and allows general users It can also be used for users who constantly receive large amounts of image data.

[0072]

As is apparent from the above description, according to the present invention, firstly, a paper jam, which is likely to occur in a U-shaped traveling path when the apparatus is downsized, has a linear traveling path. It is possible to reduce the size of the device and reduce the occurrence of paper jams.

Secondly, when receiving a large amount of image data, by inserting an external memory to increase the memory capacity as an option, the device itself can be used as a mass receiving device while being intended for normal use. can do.

Thirdly, the shape of the guide for introducing the external memory to the external memory socket is configured such that the end side of the main board to which the socket is connected is sandwiched from above and below, so that the external memory can be inserted. Force is not directly applied to the socket, and the probability that the socket will be broken or contact failure will be reduced.

Fourth, when the size width of the recording paper is regulated by the setting position of the recording paper guide in the paper feeding cassette,
Since the recording paper guide is turned over to realize the size width, it is possible to suppress the occurrence of paper jam caused by a recording paper setting error.

Fifth, when the recording paper is gradually moved backward in the course of the recording operation, the rear side of the paper feeding cassette is made an auxiliary member which can be inserted / removed so that the recording paper is simply pushed later. It is possible to align the trailing edges of the paper sheets and prevent misfeeds of recording paper sheets without causing complicated operations by the user.

Sixth, when exchanging the recording cartridge, the rotation fulcrum of the auxiliary document table, which serves as a document tray in the open position, is provided on the document table, and the document table is rotated rearward in accordance with the rotation operation. The auxiliary platen is also configured to rotate further rearward, and by limiting the maximum rotation angle of the auxiliary platen, the document platen is fixed in the closed position when the auxiliary platen is in the open position. It is possible to realize a mechanism with a simple structure in which the rotation is restricted so that the original table is not accidentally opened when the auxiliary original table is used as a document tray.
