[Prior Art]

 In recent years, personal computers, so-called personal computers, have become widespread, and have come to be widely used not only in offices but also in general households. This type of personal computer has a main CPU (central processor unit) unit, a keyboard and an LCD (liquid crystal display) unit, or a display unit such as a CRT (Cathode-Ray Tube) unit. They are arranged on a disk or placed in a dedicated rack, and the above units are electrically connected to each other with a dedicated computer cord. For this reason, it is easy to use when it is used on a desk, but the space efficiency when not in use is poor.

On the other hand, what is called a notebook type personal computer has come to be known which is compact and integrated with the CPU unit, the keyboard and the display unit and which is convenient for carrying. It is compact and has excellent storability, and is superior in usability on a desk and expandability compared to the above.

[0004]

[Problems to be solved by the device]

 However, the former one is suitable for permanent installation in an office, etc., but when the personal computer is not used on the desk, the keyboard, main unit, expansion unit, display, etc. are of a non-uniform size and stored. There is no nature. For this reason, in the office situation in Japan (especially the size of the desk), the efficiency of using the desk when the PC is not used is extremely poor, and it is inconvenient to carry it when needed. In other words, each unit is only electrically connected with a cord, and since it is a separate body in terms of shape, it is necessary to carry each unit individually. The current situation is that it is used as a stationary type on a disc, etc.

Therefore, in view of the above circumstances, the present invention can be installed and used in the same manner as the conventional one on a disc or the like, and only the units that are needed in a timely manner can be integrated by bonding them to each other. The purpose is to provide a unit-bound personal computer that can be carried around.

【Example】

 Hereinafter, an embodiment of a unit binding type personal computer according to the present invention will be described with reference to the drawings. The first embodiment shown in FIGS. 1 to 10 will be described. In FIG. 1, 1 is a CPU unit, 2 is an LCD unit, 3 is an expansion unit, and 4 is a compact keyboard unit. A male shape 5 of the binder A is provided on one surface of each of the units 1 to 4 shown in FIGS. 1 to 3, and a female shape 6 of the binder A is provided on the other surface. As shown in FIG. 4, the male shape 5 and the female shape 6 of each binding A are provided so that the units 1 to 4 can be bound so that the lengths in the vertical and horizontal directions, excluding the thickness, are the same. That is, the units 1 to 4 have the same length in the vertical and horizontal directions except for the thickness so that they can be easily bound. As shown in FIG. 5, the male shape 5 of the binding A has a movable barrel 7 and a fixed barrel 8. Two protrusions 9 are integrally provided on the outer peripheral surface of the movable barrel 7 on one end side. A base 10 is integrally provided at the other end of the movable cylinder 7, and an engaging male tool 11 is integrally provided on the base 10 so as to project therefrom. The engaging male member 11 is formed in a barbed shape with a wide central portion, and a hole is provided in the central portion to give itself elastic force. The base 10 is formed to have a diameter larger than the outer diameter of the movable barrel 7. On the other hand, the fixed cylinder 8 is designed to be integrated with or fixed to the case of each unit 1 to 4, and the small diameter portion 12 in which the movable cylinder 7 is movably accommodated and the base 10 are movable. And a large-diameter portion 13 accommodated therein, and a step portion with which the peripheral edge of the base 10 engages is formed at the boundary portion between the small-diameter portion 12 and the large-diameter portion 13. The cylindrical wall of the small diameter portion 12 has an L-shaped guide groove 14 into which the protrusion of the movable cylinder 7 is fitted. The guide groove 14 is formed so as to be cut from the opening end of the small diameter portion 12 in the direction toward the large diameter portion 13. The movable cylinder 7 is elastically biased by a spring 17 in a direction in which it projects from the fixed cylinder 8. On the other hand, the female tool 6 is composed of an elongated hole 6 shorter than the width of the engaging male tool 11. The unit inside the elongated hole 6 has a space capable of receiving the engaging male tool 11.

Of the units 1 to 4, the compact keyboard 4 and the LCD unit 2 are less likely to be bonded to one surface of another unit and then further stacked to bond another unit. Although the male shape 5 or the female shape 6 is provided only on the side, the male shape 5 or the female shape 6 may be provided on the other surface in order to stack and connect another unit. As shown in FIG. 6, the compact keyboard unit 4 has a ten-key keyboard 15 separately housed in the recess 16 on the back side, and when used, the ten-keyboard 15 is rotated 180 degrees so that the ten-keyboard 15 is placed in the recess 16. It can also be pulled out to match the surface of the main compact keyboard unit 4. In this case, the male shape 5 may be provided below the recess 16 in order to house the numeric keyboard 15 in the recess 16 on the back surface of the compact keyboard unit 4. At this time, the expansion unit 3 is provided with a female shape 6 corresponding to the position of the male shape 5 of the compact keyboard unit 4. If male shapes 5 can be provided at the four corners of the compact keyboard unit 4, it can be attached to any other unit other than the expansion unit 3, which is convenient for reference.

When the units 1 to 4 are used in a separated state, the engaging male tool 11 is retracted into the fixed cylinder 8 and is in a storage state where it does not appear to the outside. At this time, the projection 9 of the movable barrel 7 is pulled out from the guide groove 14 and engaged with the open end of the small diameter portion 12 as shown in FIG. Therefore, in order to bind the desired ones of the units 1 to 4, as shown in FIG. 8, the user's finger is put in the large diameter portion 13 and the engaging male tool 11 is grasped and rotated, and the protrusion 9 is formed. Is aligned with the position of the guide groove 14, the movable cylinder 7 slides in the direction in which it projects from the fixed cylinder 8 due to the elastic biasing force of the spring 17. The protrusion 9 moves toward the inner part in the inner groove 14 as shown in FIG. Then, the user uses the finger to turn the engagement male member 11 to position the protrusion 9 on the L-shaped bent portion 14a of the guide groove 14 as shown in FIG. If the projection 9 is located at the locking portion 14a, it will not be retracted into the fixed barrel 8 even if an external force is applied to the engaging male tool 11. Further, it goes without saying that the engaging male tool 11 does not further project from the fixed barrel 8. Therefore, the engaging male tool 11 projects outward from the case of the unit. In this manner, with the engaging male tool 11 protruding, the engaging male tool 11 is fitted into the elongated hole 18 of the female 6 of the other unit. At this time, since the wide portion of the engaging male tool 11 is formed to have a width longer than the length of the long hole 18, the wide portion of the engaging male tool 11 contracts at the hole end of the long hole 18, Next, when the wide portion of the engaging male tool 11 is fitted into the unit through the elongated hole 18, the clamping force by the hole end of the elongated hole 18 to the wide portion of the engaging male tool 11 is released, and the engaging male tool 11 itself is released. When it is returned to its original position by the restoring force, the wide portion of the engaging male tool 11 engages with the hole edge on the inner surface side of the elongated hole 18 and holds the binding between the units.

In the case of binding as described above, only the ones necessary for carrying and carrying among the units 1 to 4 are bound. For example, the binding unit A binds the LCD unit 2 to one surface of the CPU unit 1, and the binding unit A binds the compact keyboard unit 4 to the other surface of the CPU unit 1. The unit to be bound may be appropriately selected from those to be carried and used.

In order to separate the bound units from each other, if the units are separated from each other with a strong force, the engaging male tool 11 is forcibly pulled out from the elongated hole 18. Thereafter, contrary to the above, the engaging male tool 11 is rotated with a finger to be pulled out from the locking portion 14a, and then pressed against the elastic biasing force of the spring 17, and the engaging male tool 11 is further rotated to obtain a small diameter portion. It engages with the open end of 12. When the engaging male tool 11 is engaged with the open end of the small-diameter portion 12, the engaging male tool 11 retains the state of being immersed in the fixed barrel 8.

Depending on the type of the unit, it may be possible to electrically connect the units as described above when they are attached to each other. This is a second embodiment and is shown in FIG. 1, FIG. 11 and FIG. As shown in FIG. 5, a male shape 20 of a connector 19 is provided as an electrical binding tool on the surface of the CPU unit 1 to which the expansion unit 3 is bound. In the male shape 20, each of the plurality of connecting element groups 20a is formed in a banana-shaped cross section, and is capable of projecting and retracting in the CPU unit 1. That is, as shown in FIG. 11 and FIG. 12, a storage recess 21 deeper than the thickness of the male shape 20 is formed in the binding of the CPU unit 1, and a Z-shaped guide groove 22 is formed on the opposing wall surface of the storage recess 21. To do. The male shape 20 is accommodated in the accommodating concave portion 21, and the protrusions 23 protruding from both side surfaces of the base body 20b of the male shape 20 are slidably inserted into the guide grooves 22. A spring 24 for elastically urging the male shape 20 in the projecting direction is housed in the housing recess 21. On the other hand, the female shape 25 of the connector 19 is made up of a receiving type connecting element group that encloses the banana type connecting element group 20a of the male type 20.

When the expansion unit 3 is attached to the CPU unit 1, the protrusion 23 is located at one end of the Z-shaped guide groove 22 as shown in FIG. When the male shape 20 is moved along the shape of the guide groove 22 with the user's finger from the state where the male shape 20 is immersed, the connecting element group 20a of the male shape 20 is accommodated by the elastic biasing force of the spring 24. As long as the protrusion 20 projects from the inside of the guide groove 21 and the protrusion 23 is located at the other end of the guide groove 22, the male shape 20 does not sink into the storage recess 21 even when an external force is applied to the male shape 20 toward the CPU unit 1. Therefore, when the CPU unit 1 is bonded to the expansion unit 3, the connecting element group 20a of the male type 20 is fitted into the female type 25 and electrically connected. On the other hand, if the CPU unit 1 and the expansion unit 3 are separated, the connecting element group 20a of the male shape 20 is released from the female shape 25. In order to immerse the connecting element group 20a of the male shape 20 in the accommodating recess 21, the male shape 20 is moved along the Z-shape of the guide groove 22 while being pressed against the elastic biasing force of the spring 24. If the projection 23 is located at one end of the guide groove 22, the male shape 20 is held in the storage recess 21 without accidentally protruding into the storage recess 21.

FIG. 13 to FIG. 17 show a third embodiment, in which fitting grooves 32 are formed at the upper and lower ends of one surface of the CPU unit 1 and projecting ridges 33 are provided at the upper and lower ends of the other surface. It is a thing. The fitting groove 32 and the protrusion 33 are similarly formed in the other units. It goes without saying that the fitting groove 32 and the protrusion 33 are formed so as to fit into each other. For example, as shown in FIG. 13, a fitting groove 32 and a protrusion 33 are formed on a predetermined surface of the expansion unit 3.

On the other hand, a male shape 26 is provided on the rear end side of one surface of the CPU unit, and a female shape 27 is provided at a position facing the expansion unit 3. The male shape 26 is a so-called pin type in which a pin 26b is projected on a side surface of a base body 26a. The female shape 27 has a recessed shape corresponding to the male shape 26, and has a pin hole 27a into which a pin 26b of the male shape 26 is fitted, on one side surface. In the male shape 26, a concave portion 28 deeper than the thickness of the male shape 26 is formed at the rear end of one surface of the CPU unit 1, and a U-shaped internal groove 29 is formed on both side surfaces of the concave portion 28. .. In the guide groove 29, the projections 30 projecting from both side surfaces of the male base 26a are slidably fitted. A spring 31 is interposed between the base 26a of the male shape 26 and the bottom surface of the recess 28.

In the third embodiment, as shown in FIG. 14, from the state where the entire male shape 26 is accommodated in the concave portion 28, the male shape 26 is inserted in the concave portion 28 in order to bind with the female shape 27. In order to project the male base 26a, the user moves the base 26a of the male shape 26 along the shape of the guide groove 29 with a finger. Due to this movement, the elastic biasing force of the spring 31 causes the entire male shape 26 to project from the inside of the recess 28. In this protruding state, even if the projection 30 is located at the end of the guide groove 29 and an external force in the direction in which the male shape 26 is recessed into the concave portion 28 is inadvertently applied, the male shape 26 remains in the concave portion 28. Never immerse yourself in. In this way, with the male shape 26 protruding from one surface of the CPU unit 1, the male shape 26 is simply inserted into the fitting groove 32 of the CPU unit 1 and the protrusion 33 of the expansion unit 3, and the male shape 26 is recessed. It is fitted in the shape 27, and the pin 26b of the male shape 26 is fitted in the pin hole 27a of the female shape 27 to be electrically connected. On the contrary, if the CPU unit 1 and the expansion unit 3 are separated, that is, if the protrusion 33 of the expansion unit 3 is slid in the fitting groove 32 of the CPU unit 1 and the protrusion 33 is separated from the fitting groove 32, The male shape 26 separates from the female shape 27. In order to store the male shape 26 in the concave portion 28, the male shape 26 is moved along the shape of the guide groove 29 by the user's finger, and the male shape 26 is resisted against the elastic biasing force of the spring 31 and the concave portion 28 is moved. You can immerse yourself in it. In this submerged state, the projection 30 is located at the rear end portion of the guide groove 28 and is maintained in position without accidentally protruding.
