You may just hold it down from above.

Next, a method of fixing the printer unit 400 and the lower cover 100 will be described.

The position is determined by fitting the positioning boss 195 provided on the lower cover with the positioning hole 411a of the printer chassis 411. Here, since the tip of the positioning boss 195 has a conical shape, the position is guided only by dropping the printer unit 400 from above. Thereafter, the lower portion is supported by the receiving portion 196, and the upward pressing is performed by the claw portion 197 of the elastically deformed triangular claw.
It is prevented from coming off by being scratched by 11b.

Next, a method of fixing the scanner unit 300 and the lower cover 100 will be described.

Surface 1 of lower cover for receiving scanner section 300
01 is higher than the surface that receives other units,
This is a surface located in front of the printer unit 400 and above the discharged recording paper, and has a cross section that is uneven, and has a large section modulus and high strength. With such a shape,
The rigidity for supporting the printer unit and the scanner unit with the same lower cover can be set.

The positioning boss 10 provided on the lower cover
The position is determined by fitting a positioning hole (not shown) of the scanner base 334 with the positioning hole 2. Here, the positioning boss 102
Since the tip has a conical shape, the position is guided simply by dropping the scanner unit 300 from above. Thereafter, the downward direction is supported by a predetermined receiving portion (not shown) of the surface 101, and the front, rear, left and right positions are slightly away from the outer shape of the scanner base 334, and a plurality of ribs 10 provided on the lower cover 100 are provided.
3 The upward restraint is prevented from coming off by fitting the triangular claw 334a of the scanner chassis 334 to the patch claw 104 of the lower cover as shown in the figure, as described above.

As described above, while the respective units are assembled to the lower cover 100, the lower cover 100 is formed with strong ribs and walls for receiving the front, rear, left and right sides of the respective units. In addition, it is possible to form an elastically deformable patch claw shape.

Since the base of each unit is the same lower cover 100, the rigidity of the product itself is improved. Furthermore, since each unit can be dropped and assembled from above, the assembly workability is good, and the unit can be removed alone,
Good maintainability.

In the above-described embodiment, the serving section is fixed to the printer main body 400 and then the printer main body 400 is fixed to the lower cover 100. However, the feeding section and the printer main body 400 are independent units. Each of them may be fixed to the lower cover 100. When the paper is fixed to the printer main body 400, the reference position of the paper is easily determined, and the recording accuracy is improved. Further, when the printer unit 400 is directly fixed to the lower cover 100, the unit weight of the printer unit 400 can be reduced, and the assembling work is further facilitated.

The document table 2 serving as a slider cover is

The rear cover 15 serving as a hand guide
Since the power supply unit 600 is firmly fixed and shielded because it is attached to the lower cover 100 as an independent component, it may be configured integrally with the lower cover 100, the upper cover 200, or the printer unit 400. In that case, the number of parts can be reduced,
In particular, in the case where the power supply unit D is integrated with the upper cover, maintenance of the power supply unit D can be performed simply by removing the upper cover, thereby facilitating the work.

FIG. 13 is a cross-sectional view of the device 1 after completion. If the components already described are denoted by the same reference numerals and the description is omitted, the units are arranged without waste as shown in the figure. FIG. 14 is a cross-sectional view of the apparatus 1 showing a state in which the recording head 417 is replaced by opening the document table 2, and is replaced from above the printer 400 as shown.

Therefore, in order to make the recording head 417 of the printer 400 detachable from the upper side, the carriage 4
16 is a recording head attaching / detaching mechanism provided in FIG.
Is provided between the recording operation position (a) and the attachment / detachment position (b), and a storage box 444 provided with a member 422 for storing the recording head 417 obliquely from above. In the recording head 417, a recording head contact portion for energizing the recording head 417 moves the storage box 444 to a recording operation position side (to the recording operation position) against a pressing force of pressing against a carriage contact portion provided on the carriage 416 side. 15A, and a control lever 445 having a built-in compression spring 451 for moving the control lever 445 in a direction indicated by an arrow K in FIG.

When the 444 moves in the lateral direction, the contact 407b can be brought into contact with the contact 407b by moving substantially horizontally. That is, if the member 222 is not provided, the contact point 407b may be damaged, but this is prevented.

FIG. 21 shows a case in which the housing is dedicated to the printer. By allowing the housing to be operated from above and from the front, the degree of freedom in designing the cover 801 is increased as shown in the figure.

The printer section 400 is provided with a means (for example, an electrothermal converter or a laser beam) for generating thermal energy as energy used for ejecting ink even in an ink jet recording method. Although the printing apparatus of the type in which the state of the ink is changed by the energy has been described, according to such a method, it is possible to achieve higher density and higher definition of the recording.

The typical structure and principle are described in, for example, US Pat. Nos. 4,723,129 and 4,740.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 796. This method can be applied to both the so-called on-demand type and continuous type. In particular, in the case of the on-demand type, liquid (ink)
By applying at least one drive signal corresponding to the recorded information and providing a rapid temperature rise exceeding the film boiling to an electrothermal transducer arranged corresponding to the sheet or the liquid path in which Since thermal energy is generated in the electrothermal transducer and film boiling occurs on the heat-acting surface of the recording head, bubbles in the liquid (ink) corresponding to this drive signal on a one-to-one basis can be formed. It is valid. By discharging the liquid (ink) through the discharge opening by the growth and contraction of the bubble, at least one droplet is formed. When the drive signal is formed into a pulse shape, the growth and shrinkage of the bubble are performed immediately and appropriately, so that the ejection of the liquid (ink) having particularly excellent responsiveness can be achieved, which is more preferable.

As the pulse-shaped drive signal, those described in US Pat. Nos. 4,463,359 and 4,345,262 are suitable. Further, if the conditions described in US Pat. No. 4,313,124 relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

The configuration of the recording head is not limited to the combination of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angled liquid flow path) as disclosed in the above-mentioned specifications. A configuration using U.S. Pat. No. 4,558,333 or U.S. Pat. No. 4,459,600, which discloses a configuration in which a heat acting surface is arranged in a bent region, is also included in the present invention. In addition, for multiple electrothermal transducers,
JP-A-59-123670 which discloses a configuration in which a common slot is used as a discharge part of an electrothermal transducer, and JP-A-59-123670 which discloses a configuration in which an opening for absorbing a pressure wave of thermal energy corresponds to a discharge part. A configuration based on 138461 may be adopted.

Further, as a full-line type recording head having a length corresponding to the width of the maximum recording medium that can be recorded by the recording apparatus, the length is determined by combining a plurality of recording heads as disclosed in the above specification. This may be either a configuration satisfying the above requirements or a configuration as a single recording head formed integrally.

In addition, by being mounted on the apparatus main body, it is possible to make an electrical connection with the apparatus main body and supply ink from the apparatus main body. Alternatively, a cartridge type recording head provided with an ink tank may be used.

It is preferable to add recovery means for the print head, preliminary auxiliary means, and the like provided as components of the printing apparatus of the present invention since the effects of the present invention can be further stabilized. . If these are specifically mentioned, capping means for the recording head, cleaning means, pressurizing or suction means, preheating means using an electrothermal transducer or another heating element or a combination thereof, and printing Performing a preliminary ejection mode for performing another ejection is also effective for performing stable printing.

Further, the recording mode of the recording apparatus is not limited to the recording mode of only the mainstream color such as black, and may be a single recording head or a combination of a plurality of recording heads. Alternatively, the apparatus may be provided with at least one of full colors by color mixture.

In the embodiments of the present invention described above, the ink is described as a liquid. However, an ink that solidifies at room temperature or lower, or an ink that softens or liquefies at room temperature may be used. In general, in the ink jet system, the temperature of the ink itself is controlled within a range of 30 ° C. or more and 70 ° C. or less to control the temperature so that the viscosity of the ink is in a stable ejection range. It is sufficient if the ink is in a liquid state.

In addition, in order to positively prevent the temperature rise due to thermal energy as energy for changing the state of the ink from the solid state to the liquid state, the temperature is positively prevented.
Alternatively, in order to prevent evaporation of the ink, an ink which solidifies in a standing state and liquefies by heating may be used. In any case, the application of heat energy causes the ink to be liquefied by application of the heat energy according to the recording signal and the liquid ink to be ejected, or to start to solidify when reaching the recording medium. The present invention is also applicable to a case where an ink having a property of liquefying for the first time is used. In such a case, as described in JP-A-54-56847 or JP-A-60-71260, the ink is held in a liquid state or a solid state in the concave portion or through hole of the porous sheet. It is good also as a form which opposes an electrothermal transducer. In the present invention, the most effective one for each of the above-mentioned inks is to execute the above-mentioned film boiling method.

In addition, as a form of the recording apparatus according to the present invention, in addition to one provided as an image output terminal of an information processing apparatus such as a computer as an integrated or separate apparatus, a copying apparatus combined with a reader or the like, It may take the form of a facsimile machine having functions.

Another preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

For this purpose, as will be described later, the components such as a recording device, a reading device, a control circuit board, and a power supply are individually configured so that they can be easily replaced and detached.

In particular, it is assumed that the housing is formed integrally with an injection resin molding die using a predetermined resin material such as high impact polystyrene resin or ABS resin. Since including a set is a considerable initial investment, the final shape is determined after its shape and usage are sufficiently examined. Further, in the manufacturing process of the device, it is possible to minimize the fixing by the frequently used screw screw,
Since it greatly contributes to the reduction of the manufacturing cost, it is considered that no screw is used except for the electric ground in principle.

In FIG. 1, a facsimile machine 1 for a monochrome image, which is a reading and recording apparatus, has a scanner device 300, which is a document-conveying monochrome reading device, inside a housing which forms front, rear, left and right side walls as shown in FIG.

The upper cover 200 is a document width adjusting plate 3 which is adjustable in width to guide the document in the width direction, and is moved around one central portion by moving only one side. A document table 2 provided with a document width adjustment plate 3 is rotatably supported by an upper cover 200 as described later, and enables access to a recording head.

A detachable document support table 4 is provided behind the document table 2. For example, when a document of A4 size is conveyed forward toward the monochrome scanner unit 300, the rear end may hang down. I try not to.

The document conveyed forward with the document surface facing down is conveyed from below the monochrome scanner unit 300 and the color scanner unit 800 to the front of the apparatus 1 or 1000, and is placed on the document support bar 6. Is placed. The document support bar 6 is movable in the front-rear direction of the apparatus 1 and the apparatus 1000 as shown by an arrow.

On the other hand, the recording sheet conveyed to the recording apparatus is restricted in the width direction by the movement of the width adjusting plate 9 provided on the recording sheet table 401 provided on the back side of the apparatus 1 and apparatus 1000. Then, after serial recording in a printer unit to be described later, the sheet is discharged to the recording sheet table 8 below the monochrome scanner unit 300 and the color scanner unit 800. When the recording sheet is conveyed so that its longitudinal direction is in the front-rear direction of the apparatus, a rear recording sheet support table 5 and a front recording sheet support bar 7 are provided to prevent the recording sheet from sagging. I have. The support table 5 is a recording sheet table 40

It is a configuration that can be done.

For this reason, a very simple manufacturing line can be realized when assembling is automated. That is, it is possible to perform assembling without a skilled person. Alternatively, assembling by a simple operation of holding each unit by the robot apparatus and moving the unit downward is possible. Therefore, the initial investment including the injection molding die can be sufficiently complemented by simplifying the parts assembling process.

On the other hand, the upper cover 200 can be fixed without using any tools. Also,
In order to remove the upper cover 200 from the lower cover 100, referring to FIG. 1 further, in order to release the engaging portion 185, which is a male and female engaging portion, from the outside, a hole for infiltration of a tool at the cover joining surface is provided.

The hole portions 201 are formed below the claw portions 202, respectively, so that a part of the edge portion 203 is cut out. This edge 203 is a lower cover 1 to be described later.
By being sandwiched between the rib of 00 and the inner surface of the wall,
It is configured not to be deformed even when an external force acts. The upper cover 200 configured as described above is moved in the direction of arrow D10 and fixed to the lower cover 100. At this time, the four claw portions 202 are engaged with the engagement portions 185.

That is, in the plan view of the lower cover 100 in FIG. 26 and the cross-sectional view taken along the line AA in FIG. 26, the upper cover 100 is divided into upper and lower portions at almost half the height of the product. , And are fitted up and down at the outer peripheral portion. That is, a thin portion 181a is formed around the upper part of the outer wall 181 of the lower cover 100, and the lower cover rib 1 is formed so as to stand upright on the outer wall.
Many 82 are provided.

On the other hand, since the upper cover 200 is also provided with an edge portion 203 serving as a thin portion around the outer wall, the edge portion 203 of the upper cover thin portion is constituted by the lower cover thin portion 181a and the lower cover rib 182. Into the gap 183, the outer walls of the upper and lower covers are fitted to each other, and the front, rear, left and right positions are determined, thereby securing rigidity.

In addition, the height of the thin portion is higher at the edge portion 203.
It is configured to be larger than the thin portion 181 by a predetermined amount so that the clearance h can be configured. In other words, the slits are formed all around the joint of the upper and lower covers, and the joints of the upper and lower covers are made invisible with these slits.
A design effect that makes the product height appear low is secured. On the other hand, at the four corners of the lower cover, an engaging portion 185 which is a patch claw elastically deforming to the inside of the outer wall is formed, and a hole 185a is formed in the engaging portion. The upper cover has a triangular claw 2 at a position where it fits into the hole 185a.
