Abstract

PURPOSE:To realize the print of a large number of digits without providing a loading place for printer only, by loading a printer unit capable of printing a large number of digits in such way that it can be rocked freely on an upper guide plate, and fixing and printing an original with the printer unit and a lower guide plate. CONSTITUTION:When the original 1 is inserted in a direction of arrow head, a sent original advances being guided with the upper guide plate 3 and the lower guide plate 4 by a paper supplying roller 2, and carrying is completed by original carrying rollers 5, 6, and 7. The original can be read in such way that it is image-formed on a sensor 11 by a lens 10 via a fluorescent lamp 8 that is a bar-shaped light source and a mirror 9. The printer unit 13 is arranged just behind a reading point 12 and between the rollers 6 and 7 setting the supporting axis 14 of the upper guide plate 3 as a rocking fulcrum. Generally, the unit 13 is raised by a spring 15 when no print is required, and when a print operation is performed, the unit 13 is rocked downward by using a linear solenoid 16 fixed on the upper guide plate 3. Thus, it is possible to print a large number of digits by fixing the original 1 with the lower guide plate 4.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a transmitting section of a facsimile machine, and particularly relates to a printer suitable for printing and recording transmission contents such as destination number, communication number, page, etc. on a document. The present invention relates to a transmitting unit of a facsimile machine.

- [Prior Art] As shown in Fig. 3, a conventional printing/recording device is constructed above and below a paper feed guide in a facsimile machine, so it requires two pairs of paper feed mechanisms, which are the minimum required for a facsimile machine. We had to add a pair of paper feed mechanisms on the downstream side and mount them here.

As a result, the problem is that the device becomes larger, and from the positioning of the upper and lower parts of the paper feed guide, the printing part becomes a cantilever beam because it is connected outside the maximum paper width of the paper feed guide, and the document width is larger than the length of this arm. It is difficult to mount the document in the center position, and the printer prints at a position far from the center of the document width, which limits the width of the document that can be printed.Furthermore, the printing section of the printer sandwiches the document, and cantilevers the document vertically. Since the printer is divided, there are problems such as the inability to increase the size of the printer.

Further, a stamper, commonly called a completed stamp, is easy to install in terms of size, structure, etc., and the printed content is sufficient in the sense of completion of transmission, but information such as when and where is not available. Therefore, the completed stamp cannot be compared with a report of the contents of transmission and reception, which is becoming common in facsimiles, and is often insufficient in its function as a printout of transmission contents.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology has a printer unit mechanism that extends above and below the document feeding surface. Therefore, it is necessary to secure a dedicated mounting position separate from the optical system reading position etc. that is originally mounted on the main body device, which poses a problem of increasing the size of the entire device.

An object of the present invention is to centrally arrange the printer mechanism on one side of the paper feed mechanism of a facsimile machine, thereby eliminating interference with the optical reading position, etc., and making it possible to share the paper guide, platen, etc. with facsimile parts. An object of the present invention is to provide a facsimile transmission device.

(Means for solving the problem) The above purpose is to use the lower guide plate of the document feeding guide of the facsimile machine as the platen of the printer mechanism, and to mount the printer unit on the upper guide plate above the platen so as to be able to swing freely. This is achieved by synchronizing the timing with the feeding of the transmitted document, swinging the entire unit until it comes into contact with the lower guide plate only when printing is necessary, and flexibly setting how to support the unit and apply the swinging force. By automatically correcting the relative positions of the lower guide plate and performing the printing operation while ensuring that the original is fixed, there is no need to worry about excessive or insufficient printer printing strokes or interference with other functional parts. By solving this problem, it is possible to print transmission conditions using multiple digits.

[Effect]

The printing stroke of type, etc. during the printing operation of the printer is
In general, the distance between the upper and lower guide plates, which are placed for the purpose of guiding documents, is as small as a fraction of the gap between the upper and lower guide plates, so if the printer is to be installed in a fixed manner, it must be placed in the document feeding system so that it protrudes from the upper guide plate. This prevents paper feeding when feeding originals.

Additionally, in recent years, the upper and lower document guides are often made of plastic, etc. from the standpoint of mass production, and they are often deformed during operation due to heat from the document reading light source and heat generated inside the device by other parts. Therefore, when the printer is fixedly disposed on the upper guide plate, the set value may change beyond the permissible value of the printing stroke due to the difference in heat caused by the operating state of the entire apparatus.

In the present invention, as a countermeasure for this, when passing paper, the printer swings back and waits, and when the transmission is completed and printing is required, it swings forward, and the front of the printer
By pressing the original against the lower guide of the platen function,
By providing flexibility that matches the amount of deformation of the other party, it becomes possible to accurately set mutual spacing and also automatically set mutual parallelism.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional view showing the component structure of the facsimile transmitting device of the present invention. When a document 1 is inserted in the direction of the arrow, the paper feed roller 2 feeds the document as it is if it is only one sheet, and then feeds it into multiple sheets. In this case, a function is provided to automatically feed one sheet at a time from the bottom, so that the originals are fed onto the upper guide plate 3. The document advances while being guided by the lower guide plate 4, and the conveyance is completed by the document conveyance rollers 5°6.7. Information on the document is read using a fluorescent lamp 8, which is a rod-shaped light source such as a fluorescent lamp. It is read by being imaged onto a sensor 11 by a lens 10 via a mirror 9. In this device, immediately after the cumulative trailing edge passes the reading point 12, the document feeding is stopped, and the procedure after communicating with the other machine is executed. If the transmission is completed, the printer prints a printout to prove this. This is carried out by the operation of

For this reason, in the present invention, the printer unit 13 is positioned immediately after the reading point and between the document double feed roller and the document conveyance roller 6.7 at the rear end, which is in charge of the paper ejection function, and is placed on the upper guide plate. The support shaft 14 is used as a swing fulcrum. This fulcrum needs to be placed as close to the printing surface as possible so that the printing section can move up and down as much as possible, so it is inserted through the upper guide plate.
The printer unit is placed in the position shown in the figure, and has the function of swinging up and down around a fulcrum in accordance with the printing timing. Normally, when printing is not required, the printer unit is placed in a position that does not interfere with the paper feeding function. In order to wait when the printer unit is lifted upward, a spring 15 is installed between the printer unit and the upper guide plate to lift the printer unit.

Next, when performing a printing operation, in order to apply downward operating force to the printer unit, the downward movement of the oscillating motion is absorbed using the linear solenoid 16, so that the solenoid body is guided upward. It is fixed to a plate, and the tip of the plunger 17 is connected to the printer unit, and the printer unit is arranged so as to be sucked downward only when power is input. The end of the swinging is completed when the lower stopper part 18 of the printer unit contacts and is pressed against the upper platen part 19 of the lower guide plate, which also has a platen function. There are two methods for securing the distance between a part of the printer unit end stopper and the printing surface 20 of the printer: one is to ensure accuracy as a printer unit, and the other is to create a step in the platen section and secure the distance using this step.

As a result, the document is automatically pressed against the platen by a part of the printer stopper, so the relative position between the typeface and the document surface is secured, there is no problem due to equal pressure of the document floating, and when the printer is operated, Printing becomes possible.

Next, alignment in a direction perpendicular to that in FIG. 1 will be explained with reference to FIG. The rotation fulcrum 14 is a support shaft 1 that serves as a dot-like fulcrum to hold the widthwise center of the printer at one point so that the parallelism between the printer and the platen can be automatically adjusted.
4 is pressed by a spring 23 for pressing it against the boss of the upper guide plate, and one spring 15 is placed at each end of the width of the printer, and one spring 15 is placed at each end of the width of the printer. On the contrary, the power solenoid engagement point 21 is located at the center of the width. Since the swinging force naturally generates a larger force than the reaction force of the two springs, the printer unit swings downward when the solenoid is turned on. Due to variations in the spring reaction force at both ends or mismatch in parallelism between the upper and lower guide plates, one end contacts the lower guide plate first, and then the other end also contacts the lower guide plate due to the solenoid rocking force that overcomes the spring reaction force at the other end. Swinging is automatically completed and parallelism can be ensured.

Contrary to this example, the spring reaction force and rocking force solenoids may be placed in one location in the center, and the solenoids in two locations at both ends.These mechanisms allow automatic adjustment of parallelism. becomes. The above operation is possible by making the rocking force F and the spring reaction force F2 larger than the force F2, which is twice the force F1.

The stopper surface at the tip of the printer has the role of preventing the document being sent from getting into the inner part of the upper guide plate where the printer unit is exposed by tilting by the swing angle when the printer unit is waiting upwards at the child end. This ensures reliable paper feeding.

〔Effect of the invention〕

According to the present invention, it is possible to install the function of printing multiple digits using a printer with a small printing stroke without providing a dedicated mounting area for the printer.
