DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus, and more particularly to, for example, a personal computer having display means.
The present invention relates to an information processing apparatus that records on a recording sheet such as a word processor or an electronic typewriter.

[0002]

2. Description of the Related Art Conventionally, some information processing apparatuses such as a personal computer, a word processor, and an electronic typewriter have an integrated operation input unit such as a keyboard and a display unit. In recent years, the display unit is rotatably supported by a main body having an operation input unit, such as a so-called laptop type, and the display unit overlaps the operation input unit when stored, and raises the display unit when used. Many small-sized components having such a structure and excellent in transportability and storage are also seen. In many of these types of apparatuses, a printer section is mounted on the rear side of the main body (the back side of the display).

Further, small and thin information processing apparatuses called notebook type or book type, which are more excellent in portability and storability, have also appeared. With this, printers have become smaller and less expensive, and users have become more and more inexpensive. Something that can be used easily has been proposed. In this type of apparatus, the printer is provided at the rear of the main body.

On the other hand, an operation input unit is configured to be foldable with respect to an apparatus main body having a display unit, a printer is housed in the apparatus main body behind the display, and a recording medium is inserted and ejected from the upper part of the main body. Something like that.

[0005] Further, there are many so-called stationary type displays having a CRT as a display, and there is also a printer in which a printer is arranged above such a display.

[0006]

SUMMARY OF THE INVENTION Based on these various information processing apparatuses, the present inventors consider that there are the following technical problems in arranging a printer in an information processing apparatus. I found it. That is,

(1) The thickness of the recording medium is not restricted. That is, in addition to the commonly used recording media, postcards,
There is a case where recording is performed on a thick recording medium such as an envelope (hereinafter, referred to as thick paper). However, it is an object of the present invention to perform good recording on such a thick paper without causing inconvenience of conveyance.

(2) The operation required to execute recording is not complicated, and the operability is high.

(3) High visibility of the recorded matter during the recording operation. That is, for example, it is easy to see the recording medium output as a result of the recording operation while contrasting with the display screen.

(4) The information processing apparatus can be downsized while satisfying the above requirements.

And so on.

On the other hand, the conventional information processing apparatus cannot sufficiently cope with the problem.

First, as a problem common to the above-described information processing apparatuses, since a printer for performing conveyance recording by wrapping a recording medium around a paper feed roller is generally provided in these apparatuses, conveyance of thick paper such as postcards and envelopes is performed. In view of the above, there is a limit in reducing the diameter of the paper feed roller, and a large space is required in order to prevent the thick paper from being folded, so that the printer unit cannot be made smaller than a certain size.

Regarding this, in the above-mentioned notebook type or book type, the printer is provided so as to be detachable from the main body or rotatable with respect to the main body. In some cases, the recording medium is conveyed linearly in the raised state, whereby the diameter of the paper feed roller is reduced and the printer unit is reduced in size. However, due to the configuration, it is necessary to perform a complicated operation of separating the printer unit or rotating the printer unit when recording. Further, in the case of rotating, a mechanism for that is required, which hinders downsizing of the printer unit.

Further, in the information processing apparatus in which the printer section is provided behind the display section, not only the operation of folding the display section to set the recording medium on the printer section is required, but also the recorded matter is recorded in the recording process. It could not be done while staying in contrast to the display screen.

The present invention has been made in view of the above problems, and has as its object to provide an information processing apparatus that can solve the above problems.

[0017]

A typical configuration according to the present invention for achieving the above object is a lower housing , the lower housing,
It is rotatably supported by the housing, and the rotation center and the rotation end are
An upper housing provided with the rotation center portion and the rotation end portion;
It is arranged on the upper case so that it is located between
A display portion for indicating, and a rotation end side of the display portion.
From the display unit to the pivot end,
Can be displaced toward or away from the display unit
And a recording unit for recording on a recording medium.
It is characterized by doing.

[0018]

According to the present invention, the recording section is adjusted to the length of the recording medium.
The display unit so that it approaches or separates from the display unit.
This makes it possible to perform good recording regardless of the length and thickness of the recording medium without increasing the size of the apparatus.

Further, the operation of setting the recording medium required for executing the recording is not complicated, and the operability can be improved. Further, it is possible to enhance the visibility of the recorded matter in the recording operation process or after the recording, and to make it easier to see the recording medium output as a result of the recording operation, for example, in contrast to the display screen.

In this embodiment, when a recording command is given for paper feeding, first, in step S1, it is determined whether or not the recording medium 107 is present in the printer unit 105 based on the output of the sensor 119. If it exists, the process proceeds to step S3, where the recording medium 107 is conveyed in the recording conveyance direction (forward feeding), and returns to step S1.

On the other hand, if the recording medium is not present, the process proceeds to step S5, in which the recording medium 107 pinched between the discharge roller 117 and the spur 118, or abutted between them.
Is started. This processing is continued until the sensor 119 detects the lower end of the recording medium (step S

A message is displayed on the display 104 to urge the user to set 7 (steps S9 and S11). Recording medium 1
07 is detected, the reverse feed is continued, and the rotation amount of the discharge roller is counted from there (step S15,
17). That is, the length of the sent recording medium is measured. When the upper edge (the leading edge at the time of recording) of the recording medium 107 is detected, the recording medium 107 is conveyed by an appropriate amount corresponding to the distance between the sensor 119 and the recording position, and then stopped (steps S19 and S2).
1). At this time, the apparatus knows the length of the recording medium. If the distance is appropriate, the processing in step S19 is unnecessary.

The cueing of the recording medium is completed as described above. In step S23, a known recording operation by intermittent feeding of the recording medium 107 and scanning of the head cartridge 101 is executed. When there is no more data to be recorded, or when the printable length determined from the known length of the recording medium has been reached (step S25), the recording operation is stopped immediately or after recording a predetermined line. (Step S2

Next, FIG. 6 shows the display section 103 of this embodiment and the hinge section of the apparatus main body 101. In the figure, 121 is the main body 10
1, a rib that fits into the groove 106 a of the guide shaft 106, a lock pin 123 that stops the display unit 103,
25 is a spring for urging the lock pin 123. FIG.
(A) shows a state in which the printer unit 105 is extended and separated from the display unit 103. In this state, the lock pin 123 fits into the hole 103a of the display unit 103, so that the display unit 10
3 does not close. FIG. 6B shows a state in which the printer unit 105 is contracted and attached to the display unit 103, and the guide shaft 106 is shown.
Pushes down the lock pin 123 so that the display unit 103 can be rotated. FIG. 6C illustrates a state in which the display unit 103 is folded over the apparatus main body 101. The rotation of the display unit 103 causes the groove 106 a of the guide shaft 106 to engage with the rib 121, so that the printer unit 105 cannot be pulled out.

The display unit 103 having such a configuration can be used.
If the printer unit 105 is not opened, the printer unit 105 cannot be extended, and if the printer unit 105 is not contracted, the display unit 103 cannot be closed. Therefore, undesired expansion and contraction of the printer unit 105 with the display unit 103 closed can be prevented.

In this embodiment, the various effects described elsewhere can be obtained. In particular, the above-mentioned technical problem can be solved.

That is, the guide shaft 106 and the display unit 1
Since the recording medium 107 is conveyed linearly along the back surface of No. 03, good recording can be performed regardless of thick paper or thin paper without inconvenience of conveyance.

Further, as is apparent from FIG. 1, the recording can be performed while the contrast between the recording result and the display screen is maintained.

In addition, the position of the printer unit 105 is moved up and down in accordance with the length of the recording medium 107.
This can contribute to downsizing of the information processing device.

Although the display unit is foldable in the above example, the display unit may not be foldable. This is the same in the following embodiments.

Reference numeral 3 denotes a shaft connecting the left and right transmission gears. Guide shaft 20
As shown in FIG. 7, a rack 4 that engages with the transmission gear is cut on the guide shaft 106 of the first embodiment as shown in FIG.

With this configuration, the operation of pulling out the printer unit 105 at the time of printing can be performed as needed by driving the motor 201, so that the operability when using the printer is improved.

Before setting the recording medium, the printer unit 105 is moved to a required position by designating the size of the recording medium to be used for printing, and is set to return to the original position after printing is completed.

Alternatively, the printer unit 105 may be vertically driven into the recording processing unit of the first embodiment, and the printer unit 105 may be automatically moved according to the length of the recording medium as necessary without specifying the length of the recording medium. It is also possible to perform recording. In other words, if the amount of reverse feeding of the recording medium for feeding paper exceeds the length of the display unit 103, the printer unit is lifted by the amount of reverse feeding, and the recording medium is sequentially fed for printing. The printer unit 105 is lowered by the amount thus set. In this manner, the printer unit 1 always has a minimum necessary length.
05 will be lifted.

(Embodiment 3) Next, as a third embodiment of the present invention, an embodiment will be described in which a guide shaft is arranged obliquely with respect to the display unit in order to secure a paper path.

Therefore, as shown in FIG. 10, when the printer unit 105 is pulled out to use the printer, it moves to the left in the figure to secure a straight paper path. In this case, there is no need to provide a guide section by cutting the back side of the display section obliquely as in the first embodiment.

(Embodiment 4) Next, as a fourth embodiment of the present invention, the position in use when the printer unit 105 disposed above the display unit 103 opens the transport path of the recording medium, A case will be described in which the display unit 103 is provided above the display unit 103 so as to be movable between a position where the path is closed and a position where the path is not used.

FIG. 11 is a schematic diagram for explaining the movement of the printer unit. In this example, the printer unit 105 is slidably held on the upper end surface of the display unit 103 in the forward direction (FIG. 11A) and the rear direction (FIG. 11B) as shown in FIG. Display unit 1

Is a pin arranged on the display unit 103 that lifts the display.

FIG. 12 is a perspective view showing a portion where the printer unit 105 moves with respect to the guide shaft 106. Here, FIGS. 11 (a), (b), (c) and FIG. 12 (a)
(B) and (c) correspond to each other.

In FIG. 12, the guide shaft 106 is provided with a two-way groove 106a, and the printer portion 105 has an elongated hole 105a so as to fit in the groove and move in parallel. 11 and 12, first, in FIG. 11A, the printer unit 105 and the display unit 103

(Other Embodiments) In the above-described embodiment, the ink jet recording system was used as the recording unit . However, an electric current was supplied to the electrothermal converter in accordance with a recording signal, and heating was performed by the electrothermal converter to exceed nucleate boiling. It is further preferable that the recording is performed by discharging the ink from the discharge port by the growth of the generated bubble.

The typical configuration and principle are described in, for example, US Pat. Nos. 4,723,129 and 47407.
It is preferable to use the basic principle disclosed in the specification of Japanese Patent No. 96. This method can be applied to both the so-called on-demand type and the continuous type. In particular, in the case of the on-demand type, it is arranged corresponding to a sheet or a liquid path holding a liquid (ink). By applying at least one drive signal corresponding to the recording information and providing a rapid temperature rise exceeding nucleate boiling to the electrothermal transducer, heat energy is generated in the electrothermal transducer, and the recording head is driven. This is effective because film boiling occurs on the heat-acting surface, and consequently bubbles in the liquid can be formed corresponding to this drive signal on a one-to-one basis. The liquid is ejected through the ejection opening by the growth and contraction of the bubble to form at least one droplet. If this drive signal is pulse-shaped,
Since the growth and shrinkage of the bubbles are immediately and appropriately performed, particularly excellent liquid ejection 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 of the invention relating to the temperature rise rate of the heat acting surface are adopted, more excellent recording can be performed.

As the configuration of the recording head, in addition to the combination of a discharge port, a liquid path, and an electrothermal converter (a linear liquid flow path or a right-angle liquid flow path) as disclosed in the above-mentioned respective specifications, U.S. Pat. Nos. 4,558,333 and 445,960 which disclose a configuration in which a heat acting portion is arranged in a bending region.
The configuration using the specification No. 0 is also included in the present invention.

Japanese Unexamined Patent Publication No. 59-123670 discloses a configuration in which a common slit is used as a discharge portion of an electrothermal transducer for a plurality of electrothermal transducers, or an aperture for absorbing pressure waves of thermal energy. The effect of the present invention is also effective when the configuration is based on JP-A-59-138461, which discloses a configuration in which is configured to correspond to a discharge unit. That is, according to the present invention, the recording can be performed reliably and efficiently regardless of the form of the recording head.

Further, the present invention can be effectively applied to a full-line type recording head having a length corresponding to the maximum width of a recording medium on which a recording apparatus can record.

Such a recording head may have either a configuration satisfying its length by a combination of a plurality of recording heads or a configuration as a single recording head formed integrally.

In addition, even in the case of the serial type described above, the recording head fixed to the carriage or mounted on the carriage enables electrical connection with the apparatus main body and supply of ink from the apparatus main body. A replaceable chip type recording head or a cartridge type recording head in which an ink tank is provided integrally with the recording head itself may be used.

It is preferable to add recording head recovery means, preliminary auxiliary means, and the like provided as components of the recording apparatus of the present invention since the effects of the present invention can be further stabilized. Specific examples include capping means for the recording head, cleaning means, pressurizing or suction means, preheating means using an electrothermal conversion type or another heating element or a combination thereof,
Performing a preliminary ejection mode in which ejection is performed separately from printing is also effective for performing stable printing.

The type and number of recording heads mounted on the carriage are, for example, not only those provided for one color ink but also a plurality of inks having different recording colors and densities. May be provided in plurality. That is, for example, the printing mode of the printing apparatus is not limited to a printing mode of only a mainstream color such as black, and may be a combination of a plurality of print heads integrally formed. To at least one of the full-color devices.

In addition, in the above-described embodiment, the ink is described as a liquid. However, an ink which solidifies at room temperature or lower and which softens or liquefies at room temperature, or an ink jet recording system 30 ink itself
It is common to control the temperature so that the viscosity of the ink is in the stable ejection range by adjusting the temperature within the range of not less than 70 ° C and not more than 70 ° C if the ink is in a liquid state when the use recording signal is applied. good. In addition, positively prevent the temperature rise due to thermal energy by using it as energy for changing the state of the ink from a solid state to a liquid state, or use an ink that solidifies in a standing state to prevent evaporation of the ink. In any case, the ink is liquefied by the application of the heat energy according to the recording signal, and the ink is liquefied, and the liquid ink is discharged. The present invention is also applicable to a case where an ink that liquefies for the first time by energy is used.

The ink in such a case is disclosed in
No. 56847 or Japanese Patent Application Laid-Open No. Sho 60-71260, in which the porous sheet is opposed to the electrothermal converter while being held as a liquid or solid substance in the concave portion or through hole of the porous sheet. It is good. The most effective one for each of the above-mentioned inks is to execute the above-described film boiling method.
