The present stage of development of a civilization is characterized by escalating cost - value of a living space. Rather not easier to enter the main attribute of this development, namely - a personal computer, in frameworks of this tendency. The system unit, the screen monitor, the printer, the scanner, stereo speakers, the keyboard and a mousy - all this demands an individual approach that contradicts the requirement of compact allocation. Does not troubleshoot and, apparently, obvious solution, namely usage of compact portable computers, so-called notebooks. For the majority of cases their portability appears redundant for which, nevertheless, it is necessary to pay expensively. First of all, such compact device will be inevitable to have the worst parametric, than the device of the normal sizes. And it besides, that the price compact essentially above. And, at last, association in one block of three - a system unit, the screen monitor, the keyboard, moreover and the manipulator contradicts one of the main requirements of construction of technical devices - to their modularity. Modularity enables the floppy adaptation and development. All this concerns and to the offered combined scanners - to printers, and also to screen monitors with speakers.

In given article the scheme of rational allocation of personal computer blocks which is saving modularity of a construction, provides maximum compactness is represented.

First of all, it is offered to allocate the screen monitor (1) and columns (2, 2) on somebody common "tray" (3, 3). Such solution, uniting these devices in the uniform function box, nevertheless, saves possibility of operative modular replacement its components.

It is offered to put this tray on high legs or on two parallel edges (4, 4) between which to allocate the scanner (5) in the not working state. For operation the scanner is put forward from under obtained out "a tray - benches". The keyboard thus is removed aside (with turn on 90 degrees). Such solution answers that circumstance, what even developed enough user of a personal computer uses the scanner seldom enough. To allocate to it thus a separate place - it is too prodigal. Besides allocation under the screen gives rather convenient - ergonomic unity of the scanner, - its working field, with the image on the screen.

It is offered to allocate behind of the screen monitor the printer (6), paper feed in which, and also its output to carry out through "window" under the screen monitor. This "window" obtains out as a result of refusal of usage standard - the central support of the screen monitor. Instead of it, it is necessary to use side supports (7, 7). In the most simple and natural sort such constructive solution is represented as follows. The screen monitor, within the limits of technology back VESA mounts, is suspended on a horizontal tube (8). In one's turn this tube fastens to vertical sidewall (the same 7,7), allocated on "a tray for peripherals" (3, 3 ...). Such mount allows to incline the screen monitor, turning it around of an axis of a supporting tube, providing with that operative access to the printer. As a result, we get a modular construction with necessary operative access to all blocks, with a minimum of occupied square.

To the greatest degree for implementation of this solution the ink-jet printers having appropriate paper feed suit. Printer HP Deskjet 3745 especially suits. About possibility and necessary here improving it will be told below.

The second fundamental problem is allocation of a system unit. One of the most settled solutions here - allocation on an edge under desktop in the side bedside-table opened in front. However, here there is a headache an access to back - the commutative side of a system unit. Or it is necessary to provide free detour around of desktop, that basically contradicts the requirement of compactness, or to remove desktop with all computer attributes that represents the task of a power circus genre. The task of a similar genre unless not so power, access to a back commutative wall atop of desktop is. Well and, at last, classical solution - by means of promotion of a system unit forwards - possesses number of essential disadvantages. Wires should be long. To put them through pass to a back wall of a bedside-table, no less than to avoid them tangling at returning a system unit to a place, - all this task not for nervous.

It is offered to solve this problem by detachment of a system unit (9) in a separate narrow little table - a bedside-table (10), equal height with the main desktop. This little table can permanently settle down near a wall of a room, and to remove it will be necessary only the main desktop (11). Thus only it is required to shift preliminary with last considered above "a peripheral bench", - to shift (with a turn on 90 degrees) on the same "added" little table.

As a result the compact modular construction with convenient enough functional access to separate units turns out.

It is necessary to note, that constructional independence of the main desktop allows to return to it a role of dinner table, that appears very opportunely about our constrained circumstances.

Besides a computer little table with the peripheral tray allocated on it, itself is fine preparation for a separate workstation. It is necessary to add only (to add as required) a small longitudinal platform, for allocation of the keyboard, and also the put forward scanner. Here it is only necessary to provide the constructional units preventing fall forward. In described elaboration the screwed from below to legs of an added little table ingots (12, 12), appearing forwards centimeters on 20 are used.

It was above noted, that is the most complete, without additional alterations, to requirements of layout of the printer behind the screen monitor answers HP_Deskjet_3745. Pages of a paper move from below - in front, there they and come back. Thus the feeder is halved on two parts, a lobby from which reclines upwards in a non-working state. That provides maximum compactness of a construction.
However, declination upwards demands to install the screen monitor above that the thrown back part passed under it. It is necessary also because it is required lift the common cover which covers a thrown back part of the feeder.

Here three solutions are possible. To turn back-upwards screen monitor in a necessary degree. To leave a tray in the opened state (probably covering any lid). And, at last, the most interesting would be to apply here not leaning back front support to a paper, but put forward (sliding), with the small end folding plate covering an input-output in the added state, and the adding length in spread out. Such solution, only in the automated sort is used in EPSON STYLUS PHOTO R1800. Naturally, to make it in home-made conditions - it is rather difficult. Industrial release of printers with such submitting device would be rather pertinent.

It is necessary to notice, that considered upgrade will not prevent to usage of the printer outside of the considered concept of its allocation behind the screen.

And, at last, industrial release of laser printers under this concept would be very interesting. All the same they have appeared much more practical, than ink-jet. Evolution of laser printers has already brought to necessary solution. For concreteness it is possible to name HP Laser jet P1005. Laser printers have come to the feeder allocated from below, and output - return of pages back, - only on the top of the printer. It is necessary to organize only a slope-slope of degrees on 45, and also a sliding additional part of the feeder.

And again, considered upgrade will not prevent to usage of the printer outside of the considered concept of its allocation behind the screen. It will be necessary only, for already absolutely complete restoring, to add an insert without an inclination, together with the folding supports put from above.

Replacement of the ink-jet printer on laser is quite logical. However, it would be desirable to have in the arsenal and ink-jet since meanwhile on its basis color printing accessible to the wide user is realized. Here it is possible to suggest to organize little balcony, above "a tray for peripherals" or above a computer little table. And on the upper platform of this balcony to allocate the color ink-jet printer. Solution certainly bulky, at first sight, but nevertheless ... Here it is to necessary to use creative design.

The considered mount of a carrying tube in any sides is caused with its availability in handicraft conditions. With the greater technical possibilities it is possible to prolong the ends of this tube, to bend them back-downwards, and then forwards, and by that to get more elegant construction of support of the screen monitor. Though if to prolong sidewall upwards it will be possible to put on them forepart on which it will be possible to allocate the color ink-jet printer. It is obtained not a bench, but whatnot...

As the main desktop the sliding desktop with the regulated height of production of GDR (the German Democratic Republic) was used.
As an added computer little table the central curbstone of kitchen folding desktop of production of the USSR was used. In the last case it is important, that the used part of desktop has frame appearance which provides additional (side) possibilities of access to a system unit.

In a non-working state the keyboard is put vertically to a peripheral tray.
