Abstract

PURPOSE:To obtain a small-sized, low-priced bury-type facsimile equipment by pulling an operation part, etc., out of a panel to load on a freely movable chassis and containig parts except for a front part in a case main body arranged in the panel. CONSTITUTION:The parts except for the front part are contained in the case arranged in the panel. An original detection sensor 21 detects an original inserted into an original inlet at the bottom of the front operating part 18, and then a drive motor 8 begins to rotate. When a feed roller 2 conveys the original downward and a detection sensor 22 detects the tip of the original, the conveyance is so controlled that when the tip comes to a read part, it stops. the original is conveyed while a contact-type read sensor 1 reads the original line by line, and finally it is discharged out of a lower original discharge port. After a recording paper roll 4 is held by a shaft enter, and recorded by a recording part, it is cut by a cutter 7, and discharged to the front part.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a facsimile device embedded in a panel or the like.

(Prior Art) Although facsimile devices are generally desk-top type, there is a demand for small, embedded facsimile devices that use wireless technology and can be stored inside a panel, such as in a vehicle. In addition, in order to reduce the size of the document, there is a device in which the cutter is driven by a document conveying motor, but in this case, the direction of one rotation is reversed to differentiate the device (see, for example, Japanese Patent Laid-Open No. 109413/1983). Please note that this is controlled using a one-way clutch, etc.

There are problems with the accuracy of the paper feed and the price. If one motor were to drive all of the document conveyance drive, recording paper conveyance drive, and cutter drive, an electromagnetic clutch would be used to perform the intermittent operation, which would be very expensive.

(Object of the Invention) Therefore, the present invention provides a small, low-cost facsimile device that is embedded in a panel or the like.

(Structure of the Invention) D: A document reading section consisting of a document conveying means for conveying a C document and a document reading head, a recording paper roll, and a recording paper pulled out from the recording paper roll, and the recording paper is transferred to the recording head during the conveyance. A recording paper conveyance means including a feed roller that presses the recording paper, a cutter means that cuts the recording paper, a drive means that drives the document conveyance means, the recording paper conveyance means, and the cutter means;
An operation part for setting the operation of each part is mounted on a chassis that can be freely pulled out from a panel, and transmission and reception can be performed with the parts other than the front part normally housed in a case body arranged inside the panel.

(Example) An embodiment will be described in detail below with reference to one drawing.

FIG. 1 shows an embodiment of the present invention, where ① is a contact type reading sensor, 2 and 3 are feed rollers that convey the original,
4 is a recording paper roll, 5 is a recording paper pulled out from the recording paper roll 4, is conveyed, and the recording paper is transferred to a thermal head 6.
A feed roller that presses against the

7 is a cutter that cuts the recording paper, 8 and 8' are two drive motors arranged side by side on the front side and the opposite side in the drawing, and the front motor 8 is connected to pulleys 9, 10, 11,
Document feed roller 2 via belt 12 and gears 13 and 14
, 3, and also drives the cutter 7. Also, the motor 8' on the opposite side has pulleys 9', 15 and bells 1 to 1.
6 to drive the recording paper feed roller 5. Reference numeral 18 represents an operation unit for setting various operations, 19 represents a power source, and 20 represents a printed circuit board 1 that constitutes an electric circuit. The parts included in the part indicated by the arrow A-A from the two-dot chain line are mounted on a chassis (not shown) that can be freely drawn out, and usually only the front part (the right end face in the figure) is exposed, and the other parts are not shown. 1 is housed in a case body placed inside, for example, a shelf or a car panel.

Next, the operation of this embodiment will be explained. The Hx document inserted into the document entrance located below the front operation section 18 is detected by the document detection sensor 21, and the drive motor 8 starts rotating there.

The document is conveyed downward by the feed roller 2, and when the leading edge of the document is detected by the detection sensor 22, the conveyance is controlled so as to stop when the leading edge reaches the reading section. Thereafter, the document is conveyed while being read line by line by the contact type reading sensor 1, and finally discharged from the lower document outlet.

The recording paper roll 4 is held by a shaft. After the recording paper is recorded in the recording section (between the thermal head 6 and the feed roller 5), it is cut by the cutter 7 and discharged to the front section. 23
is a detection sensor for detecting the presence or absence of recording paper. The recording paper is transported by a feed roller 5 driven by a drive motor 8'.
It is transported by rotation. The cutter 7 is driven by a drive motor 8 for document conveyance, and is controlled by a cutter blade position detection sensor 24 to stay at a fixed position.

The cutter blade also rotates during reading, but there is no problem since no recording is performed, and 1. If the motor is rotated and stopped at a designated position, there will be no problem when conveying and cutting the recording paper. Also, when copying, if you do not record at the same time as reading, but instead put the scanned data into memory and then record it after reading, the paper may jam in the cutter or be cut off at unnecessary parts. Things will disappear. When cutting the recording paper, l·lux increases, so if the motor drive frequency (the number of Glock pulses) is lower than that when conveying the document, cutting becomes easier, and the motor can also be made smaller. Note that it is more advantageous to cut the recording paper while it is stopped because it does not require strict positional accuracy. In the figure, we have explained the case of two drive motors, but it is also possible to use a one-way clutch and gear connection to transport the document and cut the recording paper by rotating one motor in the forward direction, and transport the recording paper by rotating it in the reverse direction. It is.

Next, exchanging the recording paper roll will be explained. In FIG. 3, when the lever 25 is pushed in the direction of arrow C against the tensile force of the spring 26, it rotates about the fulcrum 27 and the claw 25a
is removed, the sliding portion 28 of the freely drawable chassis (not shown) is moved in the direction of the arrow (first direction) by the compression spring 29.
(front direction in the figure).

By pulling out the chassis, the recording paper roll can be easily replaced. At this point, the claw of the lever 25 comes off the slide part 28, and at the same time, the opposite side of the lever 25 pushes up one end of the bracket 30 of the thermal head 6 against the urging force of the compression spring 31, so that the slide part 28 moves in the direction D. When moving, the thermal head 6 is in a state where it escapes from the conveyance roller 5. When the chassis is pulled out, the thermal handle remains at the back, making it easy to clean the feed roller 5 and remove jammed paper. After replacing the recording paper roll, etc., when the chassis is pushed in, the claw 25a of the lever 25 engages with the slide portion 28, and the thermal head is also set at the recording position.

On the reading side, the front side can be opened around the fulcrum 32 on the lower front side, making it easy to clean the rollers and remove jams.

FIG. 2 shows another embodiment of the invention.

The arrangement of the contact type reading sensor 1 and the feed rollers 2 and 3.

This is a reverse version of the one shown in FIG. 1, and the arrangement and operation of other parts are exactly the same.

(Effects of the Invention) As described above, according to the present invention, it is possible to construct a small, compact, and low-cost embedded facsimile device, which is also extremely easy to operate and maintain.
