Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine, and more particularly to a flat and compact thin facsimile machine.

[0002]

2. Description of the Related Art Conventionally, a compact facsimile machine has been proposed. Referring to the drawing, the recording section,
The configuration of the document reading unit will be briefly described.

FIG. 10 is a cross-sectional view of a conventional facsimile apparatus, which is an example of the structure which is said to be the most compact and flat at the present time. In the figure, a first opening 203 is formed near the edge of the top surface of the housing cover 200 that also serves as a housing, and a second opening 204 is formed near the back (rear surface side) of the housing, while the housing is formed. Cover 200
A discharge port 205 is formed on the front surface of the.

In the above structure, the original G is inserted with the reading surface facing down through the first opening portion 203, and is rotated in the contact type line image sensor 12 and the contact type line image sensor 12 in a biased state. First driven dynamically
It is held between the biasing rollers 13 and is conveyed and discharged from the discharge port 205.

On the other hand, on the back side of the upper surface of the housing cover 200, a roll-shaped recording paper KR, which is a roll of heat-sensitive paper as shown in the figure, is rotatably and replaceably held in the direction of the arrow, and is a roll paper K2. The recording surface of the line thermal head 14 constituting the recording portion of the second recording roller is arranged so as to face the recording surface, and the second biasing roller 15 is rotatably driven in a biased state against the line thermal head 14. Then, the roll paper K2 is clamped and ejected to the outside after recording through the second opening portion 204.

With the above configuration, the reading section and the recording section do not overlap in the thickness direction of the housing cover 200, and the thickness dimension of the housing 200 is made small.

[0007]

However, in the above-mentioned facsimile machine, in order to reduce the thickness of the housing, the roll-shaped recording paper KR of recording paper is arranged between the reading section and the recording section. As a result, the size of the housing in the front-rear depth direction needs at least an extra amount for accommodating the roll-shaped recording paper, so that there is a problem that the depth size cannot be reduced.

Further, according to the above facsimile apparatus,
Since only roll-shaped recording paper is used as the recording paper, there is a problem that, for example, a so-called cut thermal paper of A4 size cannot be loaded in the recording section. That is, in order to be able to load such a cut sheet into the recording unit, the operation such as loading the cut sheet after removing the roll-shaped recording sheet is very troublesome, so that it is practically impossible. Is. On the other hand, when a dedicated opening for inserting cut sheets is newly provided, for example, in the vicinity of the above-described first opening, the opening and the first opening each having at least the A4 lateral dimension in the longitudinal direction are provided. Since it is not possible to guarantee the strength of the rod-shaped partition formed between the sheet and the sheet, it is virtually impossible to set the cut sheet.

If the recording paper feed path and the document feed path are provided independently of each other as in the illustrated facsimile machine, a guide member must be provided for each, which hinders size reduction. Further, as a result of providing the respective discharge ports, it becomes difficult to secure the rigidity of the housing, and it becomes difficult to secure the rigidity of the housing.

Further, according to the conventional facsimile apparatus, as shown in FIG. 10, the recording paper discharge port 20 of the housing is provided.
4, the blade portion 204a is formed integrally with the housing for the operator to cut the recording paper. However, the housing is a portion directly contacted by the operator, and is dangerous because it is a product liability. It cannot be said that there is no (PL) problem.

Therefore, the present invention has been made in view of the above problems, and its purpose is to provide a relative positioning function between a sensor and a roller that is rotated by pressing the sensor and both the original and the recording paper. It is an object of the present invention to provide a transport mechanism that can reduce the number of parts, reduce costs, and can be configured to be small and thin by using a transport mechanism having a function of guiding other functions. Another object of the present invention is to provide a small facsimile machine using the carrying mechanism.

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1A is an external perspective view of a portable facsimile apparatus 1 according to the first embodiment. Shows the state that is not set. Further, FIG. 1B is an external perspective view of the portable facsimile apparatus 1, and shows a state in which the document G and the recording sheet K1 are set and then conveyed in the arrow directions.

First, in FIG. 1A, the housing cover 2
Is a resin cover body formed by injection molding of a resin so as to be vertically separable into two parts. The housing cover 2 has a width of 300, a depth of 110, and a thickness of 32 (millimeters) as shown by the dimensions in the drawing.
Because it has a small external size, it can be easily accommodated in an office bag that is normally used, and has a built-in battery power source and facsimile function, which will be described later. If it is connected to the telephone line, it can be used anywhere such as outdoors or in a car, and it can be used as a portable facsimile machine. Furthermore, downsizing in a facsimile machine can be dealt with. As shown in FIG. 1A, the housing cover 2 of the portable facsimile apparatus 1 having the above-described outer dimensions has an opening width dimension capable of inserting a maximum width document such as a B4 horizontal size original document on the upper surface. Having the first opening 3 and B4
A second opening 4 having an opening width dimension for inserting a lateral size recording sheet is formed. Further, a discharge port 5 is formed on the front surface of the housing cover body 2 so that a B4 horizontal size document can be discharged.

Also, near the edge of the upper surface of the housing cover body 2, there are operation switches 9 such as a fine / standard mode setting switch 9a, a copy / feed mode setting switch 9b, a stop switch 9c, and a sheet. In this case, the start switch 9d is provided for performing the start operation in the transmitting state and in the receiving state without the seat. Also, to the right of these operation switches,
A display LED 8c for the power-on state and a display LED 8a for the operation error state and a display LED 8b for the setting state of the fine mode are arranged in a row on the left side. On the other hand, a power switch 7 and an external connector 6 for connecting to a telephone are arranged on the left side surface of the portable facsimile apparatus 1.

With respect to the portable facsimile machine 1 having the above-mentioned structure, as shown in FIG.
Is inserted through the first opening 3 in the direction of arrow A1 and is discharged to the outside through the discharge port 5. On the other hand, the cut sheet K1 of the thermal paper is inserted in the direction of the arrow B1 through the second opening 4 and then discharged from the above-mentioned first opening 3 in the direction of the arrow B2 (upward) in the drawing. The original reading operation and the recording operation in the facsimile apparatus can be realized in units of cut sheets (sheets).

That is, with the above configuration, the portable facsimile apparatus 1 having the above-described flat and small size is operated, for example, by holding one hand and then inserting the originals one by one with one hand. I am able to do it. Further, at the time of reception, only the heat-sensitive cut sheet K1 is set from the second opening so that it can be received. Further, when it is desired to obtain a copy, the original G and the cut sheet K1 are set at the same time without connecting to the line so that a copy can be obtained for each sheet.

Next, the internal structure will be described with reference to FIG. 2. FIG. 2 is a cross-sectional view of the portable facsimile machine 1 shown in FIG. 1 cut through a plane passing through one of the operation switches. It is a figure, and represents the internal principal part structure. In the figure, the above-mentioned housing cover 2 is configured to have a hollow box shape by a cover bottom plate 10a, a cover upper plate 10c, a cover front plate 10b, a battery accommodating portion 10d, etc. ing. And the cover upper plate 1
The first opening 3 and the second opening 4 are formed at 0c as shown in the drawing, while the discharge port 5 is formed substantially at the center of the front cover plate 10b. In addition, the switch cover 2 has a cover and a display function for the switches described above.
1 is provided.

Next, the constructions of the document reading section and the recording section will be described with reference to the exploded perspective view of FIG. 3 and a fragmentary sectional view of FIG.

First, in the structure of the document reading section, the contact sensor 12 for directly reading the document is used as the reading means. This sensor 12 is similar to that for a general facsimile machine, but has a smaller cross-sectional area. The positioning pin 12 is provided on each side of the sensor 12 and on the extension line of the reading line 12c.
a is provided. A guide / cutter member 16, which is a feature of the present invention, is fixed to the sensor 12 by using a fixing screw 12b as illustrated. In this way, the sensor 12 and the guide / cutter member 16 are integrated with each other and assembled to the sheet metal base 18.

A leaf spring 17 for urging the sensor 12 from the back side is fixed to the attachment portion 18e with a screw at a substantially central position in the width direction of the sheet metal base 18. As shown in FIG. 3, the sheet metal base 18 is bent at both ends to form both side surface portions. A hole portion 18b for supporting the sensor 12, the thermal head 14, and each roller in a predetermined state, and a groove hole portion 18a are provided on both side surface portions.
Are formed in symmetrical positions. The hole portion 18b is for rotatably supporting the CS roller 13, and the groove hole portion 18a is formed so as to extend in the normal direction of the hole portion 18b and is provided on the sensor 12. It fits into the positioning pin 12a and the bus bar of the CS roller can be aligned.

With the above construction, when the sensor 12 is assembled to the sheet metal base 18, as shown in FIG.
The positioning in the arrow B direction with respect to the S roller 13 is determined by the relationship between the positioning pin 12a and the slot portion 18a. As a result, the reading line 12c is made substantially equal to the bus bar of the CS roller 13 and is biased by the biasing spring 17. That is, the biasing spring 17 presses the sensor 12 toward the CS roller 13 at two points of the pressing portion 17a (arrow A). The pressing portion 17a is located in a direction A from the reading line 12c located on the normal line extending from the CS roller 13 in the document discharge direction.
It is provided so as to be displaced by a distance D (for example, 2 mm) on the second side. As a result, the sensor 12 generates a moment that rotates in the direction of arrow A around the reading line 12c.

In the assembled state as described above, in order to determine the mounting angle of the sensor 12, the lower end portion 16f of the guide / cutter member 16 is held in contact with the mounting portion 18e of the leaf spring 17 of the sheet metal base 18. Then, the angle of the sensor 12 with respect to the CS roller 13 is determined. From the above, as the first function of the guide / cutter member 16, the reading line 12c of the sensor 12 provided integrally is provided.
Sensor 12 for accurately positioning the bar on the bus bar of the CS roller 13
One of the points is the positioning.

In the operation of the reading section provided as described above, first, the original G is inserted into the inside from the opening 3 and guided along the guide surface 16a of the guide / cutter member 16 to form the reading line 12c. After reaching the portion sandwiched by the CS rollers 13, the CS roller 13 is driven in the counterclockwise direction and the document is discharged from the opening 5 to the outside.

On the other hand, the recording paper K is inserted through the opening, printed while generating a predetermined printing pressure between the thermal head 14 and the TPH roller 15, and then along the guide surface 16b of the guide / cutter member 16. It is guided and turned upward, and discharged from the opening 3 to the outside. From the above, as the second function of the guide / cutter member 16, by forming the guide surfaces 16a and 16b in a front-back relationship,
The point is that it functions as a document guide member and a recording paper guide member.

Further, the guide / cutter member 16 is formed with a blade portion 16e for cutting the recording paper at the end thereof, and, for example, the recording paper having a predetermined margin conveyed after the recording operation is completed. By pulling in the direction shown in the figure along the blade portion 16e, the leading end portion of the recording paper can be aligned and cut. Further, the blade portion 16e is, as shown in the drawing, from the surface of the opening portion 3 of the housing,
It is provided so that it will be recessed by about 1.5 mm (distance E), and consideration is given so that there is no danger even if the operator directly touches the surface of the housing, which causes a problem in product liability (PL). I try not to. From the above, the third function of the guide / cutter member 16 is a function as a recording paper cutter.

Next, the structure of the recording unit will be described. The sheet metal base 18 is rotatably supported by a second biasing roller, which is a TPH roller 15 that conveys the cut sheet K1 of the thermal paper. Therefore, the cut sheet K1 is brought into close contact with the recording portion of the line thermal head 14 to obtain a frictional force and carry it. In this way, the outer peripheral surface of the TPHS roller 15 is always biased against the recording portion of the line thermal head 14 in order to bring it into close contact. In order to achieve this state, the line thermal head 14 is fixed to the thermal head plate 19 as shown in the drawing, and the hole portion 19a formed in the thermal head plate 19 is provided with the second opening described above. A stud 10f extending from the back surface of the portion 4 and a stud 10e vertically extending from the top of the cover bottom plate 10a are swingably held and prevented from falling off. This thermal head plate 19
By the coil spring 20 held in a compressed state between the back surface of the thermal head plate and the sheet metal base 18, T
The recording unit of the line thermal head 14 is always biased toward the PH roller 15 side.

Here, as described above, the CS roller 13 and T
In order to keep the PH roller 15 always energized and enable each roller to be driven, the friction coefficient of each roller with respect to the reading section of the contact sensor or the recording section of the line thermal head is set to the original or the recording paper. It may be set so as to be smaller than the friction coefficient of each roller with respect to the rollers. Therefore, a special material is used for the outer peripheral surfaces of the CS roller 13 and the TPH roller 15 instead of the usual rubber material.

Next, the electronic board that executes the facsimile function is a chip board 28 on which surface mounted components such as LSI chips, IC chips, chip components, etc. are mounted as shown in the figure, and resistors, capacitors, diodes, etc. Discrete board 2 mounted through reflow solder bath
