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 lightweight and compact facsimile machine.

[0002]

2. Description of the Related Art Conventionally, a miniaturized facsimile machine is known in which a recording section and a reading section are separately configured. According to such an apparatus, an image sensor and a rotary drive in a biased state with respect to the image sensor are known. And a first pressing release mechanism for separating the first biasing roller, which is in a biased state in the reading unit, from the image sensor while the thermal head is provided. And a second urging roller urged by the thermal head to form a recording section, and a second pressure releasing mechanism for separating the second urging roller from the recording section is used.

In the above structure, when the original or recording paper (sheet) is jammed during setting or transportation, the image sensor is urged to return to the normal state. The first pressing release mechanism is operated to separate the first biasing roller, or the second pressing release mechanism is operated to separate the second biasing roller biased against the thermal head. . That is, the dedicated first and second pressing release mechanisms are provided for releasing troubles when the original and the recording sheet are conveyed.

[0004]

However, in the above-mentioned conventional example, since the first pressing release mechanism and the second pressing release mechanism are respectively provided, the mechanism of the entire apparatus becomes complicated, and There is a problem that the size of the entire device is increased.

Moreover, according to the above-mentioned facsimile apparatus, since the drive motors for the first urging roller and the second urging roller are independently provided, the power consumption at the time of driving each roller increases, In addition, there is a problem that the number of constituent parts increases and the weight increases. Therefore, the present invention has been made in view of the above-mentioned problems, and in a facsimile apparatus, a jam release mechanism is not provided for releasing the pressed state of the rollers provided in the reading unit and the recording unit, respectively. The present invention aims to achieve downsizing, reduction in the number of parts, and cost reduction by making it possible to perform processing, pull out originals and recording paper, and simplify the reading unit and recording unit. .

[0006]

[Means for Solving the Problems] and

In order to solve the above-mentioned problems and to achieve the object, the present invention uses a motor capable of rotating in the forward and reverse directions, and when the motor rotates in one direction in the middle of the power transmission mechanism of each biasing roller, A swinging mechanism that meshes so as to drive the first biasing roller and that meshes so as to drive both the first biasing roller and the second biasing roller when the motor rotates in the other direction, After the end of each operation, the rocking mechanism meshes so as to drive only the first biasing roller, whereby the second biasing roller becomes independent of the power transmission mechanism, and the second biasing roller The recording paper held between the thermal head and the thermal head can be easily removed.

Further, even when the second urging roller is in mesh with the power transmission mechanism, the document held between the second urging roller and the contact image sensor is pulled out in the document conveying direction, Due to the characteristics of the swing mechanism, the swing mechanism is separated from the gear on the side of the second biasing roller so that the document can be easily taken out.

Therefore, it is possible to carry out a recovery process for an abnormal state such as a jam of a document or a recording sheet without providing the first and second pressing release mechanisms in the reading section and the recording section as in the conventional facsimile apparatus. Moreover, the entire device can be made compact.

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 to select the place of use, such as outdoors or in a car, and it can be used as a portable facsimile machine. Furthermore, it is possible to deal with downsizing in a facsimile machine.

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 apparatus 1 having the above-described structure, the original surface Ga of the original G is read 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-described configuration, the portable facsimile apparatus 1 configured to be flat and small is operated, for example, by holding it with 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 along a plane passing through one of the operation switches. It is a figure, and represents the internal principal part structure.

C by a spring 17 whose one end is fixed to a stud 18e integrally provided on the sheet metal base 18.
The S roller 13 side is always biased. The sensor base plate 16 has a cross-sectional shape as shown in the drawing, and guides the document G and forms the leading end portion 16e sharply, and also has a shape along the outer peripheral surface of the TPH roller 15 of the recording unit described later. The cut sheet is guided to the first opening 3 and is torn at the tip 16e. Next, the structure of the recording unit will be described. The sheet metal base 18 is provided with a second urging roller, which is rotatably supported by the TPH roller 15 that conveys the cut sheet K1 of the thermal paper. The paper K1 is brought into close contact with the recording portion of the line thermal head 14 so as 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 a stud 10f extending from the back surface of the second opening 4 described above.

The recording unit of the line thermal head 14 is constantly urged toward the roller 15.

Here, as described above, the CS roller 13 and T
In order to keep the PH roller 15 always energized and to drive each roller with a low load, the friction coefficient of each roller with respect to the reading unit of the contact sensor or the recording unit of the line thermal head is set to the original or recording. It is desirable to set the friction coefficient to be smaller than the friction coefficient of each roller with respect to the paper. 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 for executing the facsimile function is a chip board 28 on which surface-mounted components such as LSI chips, IC chips, and chip components are mounted as shown in the figure, and resistors, capacitors, diodes, etc. Discrete board 2 mounted through reflow solder bath

Further, a fourth gear 63, which is rotatably supported by a stud 57, meshes with the gear.

In the middle of the power transmission mechanism constructed as described above, when the pulse motor 30 rotates in one direction, only the CS roller 13, which is the first biasing roller, is driven in a fixed direction. An oscillating mechanism that drives both the CS roller 13 and the TPH roller 15 that is the second urging roller in a fixed direction when the pulse motor 30 rotates in the opposite direction is provided. In this swinging mechanism, the sun gear 64 is constantly meshed with the fourth gear 63, and is rotatably supported together with the bracket 73 by the studs 57 vertically provided on the side surface of the sheet metal base 18. . The bracket 73 is provided with two studs 57, respectively, and pivotally supports a first planetary gear 65 and a second planetary gear 66, which are in mesh with the sun gear 64.

As a result, the CS roller gear 70 meshed with the intermediate gear 69 is driven in the direction of the arrow in the drawing, and the CS roller 13 is driven in the direction of the arrow in the drawing.

Next, in FIG. 6B, the fourth gear 63 is driven in the direction of the double arrow in the figure, and the sun gear 64 meshing with this is driven in the direction of the double arrow in the figure. .
As a result, the planetary gears 65, 66 pivotally supported by the bracket 73 are also rotated, but due to the action of the above-mentioned wave washer 68, a rotational force in the clockwise direction is generated in the bracket 73, and the first rotation is generated. The planetary gear 65 is separated from the meshed state with the intermediate gear 69 and is in mesh with the TPH roller gear 71. Further, the second planetary gear is brought into a state of meshing with the CS roller gear 70 from the lower side, and is in a state of driving the CS roller gear 70 in the double arrow direction in the drawing.

Perform the copy operation again. On the other hand, in step S54, if the OFF state of the DES sensor 22 continues for a certain period of time, it is determined that there is no next original document, and the copy operation ends in step S56. When the copy operation is completed, step S57
12, drive the pulse motor 30 in the forward direction, and
As shown in (a), the first planetary gear 65 meshes with the intermediate gear 69, and the TPH roller gear 71 is separated from the first planetary gear 65. Next, in step S40, the standby state is entered again.

Next, the operation when the stop switch 9c is pressed and the operation example when the power switch 7 is turned from the OFF state to the ON state will be described with reference to the flowcharts of FIGS.

First, in FIG. 17, when the stop switch 9c is pressed in step S60, the process proceeds to step S61, and it is determined whether or not each mode such as transmission and reception is completed. If each mode has not ended, step S
Proceed to 62 to stop and end each mode. When each mode ends, the process proceeds to step S63 and the pulse motor 30
Is driven in the positive direction to mesh the first planetary gear 65 with the intermediate gear 69 as shown in FIG.
The PH roller gear 71 is separated from the first planetary gear 65. Next, the process proceeds to step S64 and the standby state is set.

Next, the operation when the power switch 7 is turned on will be described with reference to the flowchart of FIG. First, when the power switch 7 is turned on in step S70, the process proceeds to step S71 and initialization is performed. Next, in step S72, the pulse motor 30 is driven in the forward direction, and as shown in FIG.
The planetary gear 65 meshes with the intermediate gear 69, and TP
The H roller gear 71 is set in a state of being separated from the first planetary gear 65. Next, the process proceeds to step S73, and the standby state is set.

As described above, in the present embodiment, after each operation such as transmission, reception, copy, etc. is completed, or after the stop switch 9c is pressed, or after the power switch 7 is turned on ( (Transmission mode is in operation),
The TPH roller gear 71 is separated from the first planetary gear 65, and is in a state of not meshing with the power transmission mechanism. For this reason, the frictional load applied to the TPH roller 15 is removed, and the TPH roller 15 is in a freely rotatable state.

In the embodiment described above, the recording paper K1 needs to be pulled out from the facsimile apparatus 1 when a jam occurs for some reason during the recording operation or when the roll sheet holder 40 is removed from the facsimile apparatus 1. However, as described above, after each operation, T
Since the PH roller 15 is freely rotatable, the recording paper K
It is possible to pull out 1 in the carrying direction or in the opposite direction. Also, even if the power is turned off during the recording operation,
When turned on, the recording paper K1 can be pulled out.

On the other hand, the CS roller 13 is not rotatable because the CS roller gear 70 meshes with the intermediate gear 69 and the intermediate gear 69 meshes with the first planetary gear 65. However, when the document G is pulled out from the facsimile apparatus 1, it can be easily pulled out by pulling out the document G in the conveying direction.
Will be described with reference to.

First, in FIG. 19A, when the document G is pulled out in the conveying direction, the CS roller 13 is rotated together, and the CS roller gear 70 and the intermediate gear 69 rotate in the direction shown by the arrow in the figure. As a result, the intermediate gear 69
FIG. 1 is an enlarged view of a meshing portion between the first planetary gear 65 and the first planetary gear 65.
As shown in FIG. 9B, since the intermediate gear 69 has the component in the direction of arrow E2 in the first planetary gear 65, the swing mechanism moves in the direction of arrow L, and the first planetary gear 65 is separated from the intermediate gear 69. CS roller 1 to try
3 is in a freely rotatable state, and the document G can be easily pulled out.

However, when the document G is pulled out in the direction opposite to the conveying direction, the swing mechanism tries to move in the direction opposite to the arrow L and the CS roller 13 cannot rotate, but the CS roller 13 cannot rotate. It is also possible to pull out the document G while sliding it with respect to the CS roller 13 by reducing the urging force within the range in which the document G can be conveyed. That is, in the present embodiment, since there is no automatic sheet feeder for the original G and the path of the original G is also close to a straight line, the load for conveying the original G is small, and therefore the force for conveying the original G is small. Therefore, the urging force of the CS roller 13 can be considerably reduced.

In this embodiment, the rocking mechanism is made to mesh with the CS roller 13 side.
Neither the roller 13 side nor the TPH roller 15 side meshes,
That is, if the first planetary gear 65 is held in the middle of the intermediate gear 69 and the TPH gear 71, it is possible to easily pull out the document in the reverse direction of the transport direction regardless of the pulling direction.

However, a mechanism for holding the swinging mechanism between the intermediate gear 69 and the TPH gear 71 is required, and the holding mechanism must meet the conditions for portable facsimile equipment.
That is, in consideration of carrying, etc., since the swinging mechanism must be sufficient so as not to move due to external force such as vibration, the holding mechanism becomes large in size and complicated, and therefore the facsimile apparatus which is the object of the present invention. This is contrary to the miniaturization, and the above-mentioned configuration is optimal after all.

As a result of the above operation, after the oscillating mechanism described above is completed, after the stop switch is pressed, or the power switch is turned on, the CS roller is engaged with the TPH,
By setting the rollers to be freely rotatable, the original document and the recording paper can be easily extracted without separately providing a mechanism for releasing the urging force of the CS roller and the TPH roller.

As a result of the above, each biasing roller can be selectively driven only by changing the driving direction of one pulse motor 30, power consumption can be reduced, and the number of parts can be reduced to reduce the cost. it can.
