Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a portable electronic device with a keyboard.

Prior Art In electronic devices such as portable electronic desktop calculators, as described in Japanese Utility Model Publication No. 47-27458, a keyboard is arranged on the top of the main body, which can be freely rotated by attaching a lid to the main body. There is a type of lid which is provided with a display section on the inner surface of the lid.

Problems to be Solved by the Invention However, since the main body and the keyboard are portable and small, it becomes difficult to see the characters on the keyboard when it is moved away from the body, so it is inevitably necessary to use it by pulling it close to the body. As a result, the display section held on the lid connected to the main body is also pulled toward the user's hand, making it difficult to see. As a result, the user is forced to take an unnatural posture of hunching his back and lowering his head to look into the display, which easily fatigues both his body and eyes. In addition, if the display is made larger to make it even slightly easier to see, the weight of the display will increase, putting a strain on the hinge that adjusts the rotation angle of the lid, and reinforcing it by making the hinge larger than the lid. It has to be done, but this has the problem of spoiling the design.

This invention was made in view of the above points, and allows the positions of the keyboard and display board to be adjusted according to the body shape of the operator.
To provide a portable electronic device with a keyboard that can enlarge a display board, block outside light with a case to make it as easy to see as a hooded device, and be safely carried.

Means for Solving the Problems A recess with a large opening area is formed on one side of the case, a display board is buried in the bottom of the recess, and a cover is removably fitted into the opening of the recess. an engaging recess is formed in one of the cover and the case, an engaging element is formed in the other, a keyboard is provided on the inner surface of the cover, and a connecting part is formed between the cover and the case. A handle is rotatably attached to the case, and is connected to the case via a cable and positioned at a position for diagonally supporting the case and a position for carrying the case.

Function When carrying or storing the keyboard, fit the cover into the recess of the case with the keyboard facing inward.
Since the cover and the case engage with each other through the engagement recess and the engagement element, the cover does not fall off from the case and can maintain a stable state.
In addition, the case is equipped with a handle, making it easy to carry.When in use, the handle supports the case diagonally to make it easier to see the display board.Furthermore, the cover can be removed independently from the case. Since they can be separated, the position of the keyboard and the display board relative to the body can be determined arbitrarily.Moreover, the display board held in the case can be made larger, and the wall around the recess can be removed from the outside. It can function as a hood that blocks light, making it extremely easy to use.

Embodiment An embodiment of the present invention will be described based on FIGS. 1 and 2. A handle 2 is rotatably attached to a flat case 1. In addition, the case 1 has a storage section 3 that stores an electronic circuit (not shown) having the function of a microcomputer, and is formed close to one side, and has the largest opening area excluding this storage section 3. A recessed portion 4 is formed on one surface of the case 1. A display board 5 such as a CRT is buried in the bottom of the recess 4.

Next, a cover 6 and an attached cover 7 are provided to cover the opening surface of the recess 4, and engagement recesses 8 are formed on both sides of the cover 6. Although not shown, similar engagement recesses 8 are formed on both sides of the attached cover 7, and engagers 9 that elastically engage with these engagement recesses 8 are provided in the recess 4 so as to be freely retractable from both sides. There is. Further, a keyboard 10 is provided on the inner surface of the cover 6. Furthermore, a cable 11 for inputting signals from the keyboard 10 to the electronic circuit inside the case 1 is provided on the cover 6, and a groove (not shown) for extending and holding this cable 11 is formed on one side edge 12 of the cover 6. There is. A connecting portion 13 is formed in the case 1 to connect the cable 11 to an electronic circuit.
Further, legs 14 are fitted to the outer surface of the cover 6 so as to be able to rise and fall freely, and finger hook recesses 15 for raising these legs 14 are formed in the cover 6.

In this configuration, the cover 6 and the attached cover 7 are fitted into the recess 4 when being carried around or stored. When in use, the cover 6 is removed by raising the legs 14, grasping and pulling these legs 14. The attached cover 7 can be pulled up by inserting your hand into the space where the cover 6 is removed. And leg 1
4 on the table with the keyboard 10 facing upward, and connect the cable 11 to the connection part 13. The handle 2 rotates to an arbitrary angle and comes into contact with the table as a stand, thereby selecting the angle of inclination of the display board 5.

In this way, since the case 1 holding the display board 5 and the cover 6 holding the keyboard 10 can be separated, the keyboard 10 and the display board 5 can be placed independently in a desired position relative to the body. This allows the user to operate the keyboard 10 and view the display board 5 in the correct posture. In addition, although the case 1 is rotatably held by the handle 2, it is partially supported by the table, so even if the weight increases, it will not rotate relative to the handle 2 as long as it is placed on the table. do not have. As a result, the display board 5
can be enlarged without fear of increasing weight, and furthermore, the four sides around the recess 4 function as a hood that blocks external light, thus making the displayed contents extremely easy to see. I can do it.

In addition, as shown in FIG. 3, the display board 5 is rotatably attached to the case 1, and the display board 5 is
A dial 16 is fixed to a support shaft (not shown) protruding from the center of both sides, and the dial 16 is rotated together with the support shaft and the display board 5, thereby adjusting the display board 5 to an angle that is easy to see. Good too.
Furthermore, the number of keyboard 10 and electronic circuits is at most 6.
Although it is connected by a core cable 11, signals may be input from the keyboard 10 to the electronic circuit by infrared communication.

Effects of the Invention As described above, a recess with a large opening area is formed on one side of the case, a display board is buried in the bottom of the recess, and a cover is attached to the recess, which is removably fitted to the opening surface of the recess. provided independently from the case, an engaging recess is formed in one of the cover and the case, and an engaging element is formed in the other, a keyboard is disposed on the inner surface of the cover, and the cover and the case are connected. A handle is rotatably attached to the case, which is connected to the case by a cable through a connecting part, and is positioned in a position to support the case diagonally and a position to carry the case, so when carrying or storing the keyboard, The cover is fitted into the concave part of the case with the part facing inward, but since the cover and the case engage with each other by the engaging concave part and the engaging element, the cover will not fall off from the case.
It can maintain a stable state, and the case is equipped with a handle, making it easy to carry.When in use, the handle can be used to support the case diagonally to make it easier to see the display board. Furthermore, since the cover can be separated independently from the case, the position of the keyboard and the display board relative to the body can be arbitrarily determined, and the display board held in the case can be enlarged. The wall around the recess can function as a hood that blocks external light, making it extremely easy to use.
