Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to an improvement of a handheld computer with excellent portability.

(B) Prior Art In consideration of storage in a suitcase or the like, a general handheld computer has a generally rectangular parallelepiped shape when not in use, as shown in FIG. 4, for example. On the other hand, when in use, the lid B, which is rotatably supported in the center of the main body A and has a screen S on the inner surface, is opened, and the keyboard K protected by the lid is opened using the display on the screen. This allows you to perform signal processing while operating the device. At this time, connection with external peripheral devices is achieved through a connector C provided at the back of the main body. When this connector C is not in use, it is protected by a cover D, but when it is in use, this cover D is rotated relative to the main body A and is fixed at that rotation position by the locking portion E, so that the main body A is placed against the table T. It is configured to be used as a leg that is tilted forward. The operability of the keyboard K is also improved (Fig. 5). This kind of handheld computer is manufactured by Nippon Data
This is shown in the introductory catalog of General's "DATA GENERAL One".

(c) Problems that the invention aims to solve In the handheld computer mentioned above,
When in use, the cover must be opened and the cover must be used as legs to position the device, making it impossible to operate the keyboard with the main body in a horizontal position. Further, it is necessary to provide a lock portion for locking the opened cover to the main body, and a space is required to store this lock portion when not in use, resulting in a complicated structure and high cost. Another disadvantage is that the effective space becomes narrower.

This invention was created in view of the above points,
It is an object of the present invention to provide a handheld computer with a simple structure that can be used even when the main body is set horizontally or tilted at a predetermined angle.

(d) Means for solving the problem The present invention provides a rotating cover whose lower part is rotatably supported on the cabinet in order to permit or prohibit the connection of external electrical equipment to signal relay means such as connectors. The rotary cover is placed in a first position where it is supported by the cabinet so as to prohibit the above connection, a second position where it is supported on an extension plane of the bottom part of the cabinet, and a second position where it is supported on an extended plane of the bottom part of the cabinet. The handheld computer is characterized in that it can be selectively set to a third position in which the bottom part is partially lifted from the support table.

(e) Effect: The present invention protects the signal relay means including the cabinet from the outside by setting the rotary cover in the first position and setting the handheld computer in a state where it is not in use, and improves the portability of the handheld computer. In addition, by setting the rotary cover in the second position (simply placing the rotary cover on the support table that constitutes the extension plane of the bottom part), the external electrical equipment can be connected to the signal relay means while the angle of the cabinet with respect to the support table is made horizontal. The signal processing means inside the cabinet can be operated. Further, by setting the rotary cover in the third position, the cabinet can be partially lifted off the support table supporting it, thereby improving the operability of the keyboard. In particular, when in use, the cabinet can be placed horizontally or tilted at a predetermined angle with respect to the support table, allowing the user to operate the keyboard in a convenient manner.

(f) Embodiment FIGS. 1, 2, and 3 show sectional views of one embodiment of the present invention in different states. In each figure, 1 is a plurality of keys, 2 is a cabinet that stores signal processing means (not shown) and has a plurality of keys 1 disposed on the top surface 2a, and 3 is a signal processing means and an external electric device (printer). etc.), a signal relay means such as a connector is provided on the side surface 2b of the cabinet 2, and 4 is for allowing or prohibiting the connection of external electrical equipment to this signal relay means. The lower part 2c of the cabinet 2 is the support shaft.
(5) is a rotating cover that is rotatably supported; and 6 is a lid that is rotatably supported with respect to the cabinet 2 and has a screen 7 on its inner surface for displaying an image.

A plurality of keys 1 are arranged on the upper surface 2a of a cabinet 2 so as to be movable toward and away from the cabinet 2, and when the device is not in use, it is covered with a lid 6 as shown in FIG. When the lid of the body 6 is opened, it is set in a usable state as shown in FIGS. 2 and 3. The operation of each key is recognized by the signal processing means, and predetermined signal processing is performed, an image is given on the screen 7 as necessary, and the operation of waiting for the next key operation is performed.

The cabinet 2 has a support shaft 5 for freely rotatably supporting the rotary cover 4 disposed below the side surface 2b, and receives an outer surface 4a of the rotary cover 4 on the outer surface adjacent to the support shaft. It has a slope 2d. Further, above the upper surface 2a of the cabinet 2, there is provided a support shaft 8 for allowing the rotational movement of the lid 6, and the lid 8 can be placed in a first position as shown in FIG. and a second position as shown in FIG.
A locking means (not shown) such as a magnetic coupling means or an articulating mechanism is provided between the lid body 6 and the lid body 6.

The signal relay means 3 is composed of a plurality of connectors for connecting external electrical devices such as an external expansion bus, a barcode reader, a video device, a printer, and an RS232C. The receptacles are oriented towards the outside of the cabinet 2 to allow this. This insertion port is arranged to be opened and closed by the rotating cover 4.

The rotary cover 4 is supported by a support shaft 5 so as to be completely rotatable, and in a first position (FIG. 1 position) where it is supported by the cabinet 2 so as to prohibit the above-mentioned connection, there is a well-known mechanism that can be attached to and detached from the cabinet 2. Its position is held by locking means (not shown; magnetic or mechanical coupling means may be used). By releasing the lock by this locking means, the rotating cover 4 naturally falls around the support shaft 5, and the support table 1 supporting the cabinet 2 is rotated.
The second position (FIG. 2 position) is taken where it is placed on 0. At this time, the signal relay means 3 is opened to allow connection of the plug 9 having the connection cable 11. By setting the lid 6 to the second position and exposing the plurality of keys 1, the device is ready for use. Further, in order to tilt the plurality of keys 1 forward, the rotary cover 4 is further rotated to the third position as shown in FIG.
Let it partially float from the top. At this time, the front edge 2e of the bottom surface of the cabinet 2 and the tip 4b of the rotary cover 4 abut against the support table 10 and are supported. Further, the outer surface 4a of the rotary cover 4 on the base side and the slope 2d of the cabinet 2 abut each other to support the cabinet 2.

(g) Effects of the invention The invention includes a rotating cover that is rotatably supported by the cabinet and opens and closes the signal relay means, and this rotating cover is located at the first position where the signal relay means is closed and on the extension plane of the bottom of the cabinet. Since the rotary cover is configured to take the second position in which it is supported, and the third position in which it goes around to the bottom side of the cabinet and supports the bottom part by lifting it off the support table, the rotary cover can be moved to the second position or the third position. The signal relay means can be opened in any position, i.e., it can be used either when the cabinet is placed horizontally on the support table or when it is tilted at a predetermined angle. This is practical as it allows you to use the keyboard in a comfortable position.
