BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to electronic equipment such as word processors and computers.

0002

2. Description of the Related Art Conventionally, electronic devices such as word processors and computers have been constructed as shown in FIGS. 6(a) and 6(b). As shown in FIG. 6, the cursor CS on the screen is moved by normal keyboard operations. For example, when moving the cursor CS from point A to point P on the display screen, the user presses the cursor movement key CSK appropriately (presses the key in the direction you want to move) and moves the cursor CS to point A via path A1 or path A2. Move from point to point P.

By the way, when moving the cursor CS from point A to point P, rather than going through route A1 or route A2,
The moving distance (moving time) of the cursor CS is shorter if the cursor CS is moved via route A3.

However, conventional electronic devices do not have a diagonal movement function, and it is impossible for the cursor CS to follow the path A3. Further, adding a cursor movement key (for example, a key for instructing a diagonal direction) in order to move the cursor CS along the path A3 is contrary to the recent trend towards space saving and miniaturization.

[0005] Therefore, as a means to solve the above-mentioned problems, it is best to use a joystick to move the cursor on the screen in terms of space saving and miniaturization.

[0006]

[Problems to be Solved by the Invention] However, in conventional electronic equipment, when a joystick is provided on the keyboard, the protrusion of the joystick causes the display B to
It is impossible to close and carry it easily.

The present invention has been made in view of the above circumstances, and an object thereof is to provide an electronic device that can be easily carried and that allows the display to be closed even when a joystick is provided on the keyboard. be.

[0008]

[Means for Solving the Problems] In order to achieve the above object, the present invention includes a control means for exposing and retracting the joystick from the main body in response to opening and closing of the display.

[0009]

[Operation] In the present invention, as the display device is opened and closed,
The solenoid valve is turned on and off, or the spring is expanded and contracted,
Alternatively, the joystick is exposed and retracted by rotating the gear.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram showing an embodiment of an electronic device according to the present invention. In the figure, 1 is a joystick, 1a is a lever, 2 is an electromagnetic solenoid, 3 is a display, and 4
is the spring, 5 is the limit switch, 6 is the electronic device body, 7
is a keyboard, and numerals 2, 4, and 5 constitute control means.

In FIG. 1, a joystick 1 is fitted into a recess 10 of a main body 6 and is slidable vertically. The limit switch 5 protrudes from the side surface of the main body 6. FIG. 1 shows the display device 3 in an open state, and the display device 3
If is at the SPH position, it indicates an open state. When the display 3 is in the closed state, the limit switch 5 is pushed into the wall of the protrusion 9 of the main body 6 by the wall of the recess 8 of the display 3 (see FIG. 2), and outputs an off signal. . The electromagnetic solenoid 2 is turned off by an off signal from the limit switch 5, and the rod 2a is drawn into the electromagnetic solenoid 2, so that the joystick 1 is stored in the main body 6. When the indicator 3 is in the open state, the limit switch 5 does not come into contact with the wall of the recess 8 of the indicator 3, but protrudes from the wall of the main body 6, and outputs an on signal. At this time, the electromagnetic solenoid 2 is turned on by the on signal from the limit switch 5, and the rod 2a is pushed out from within the electromagnetic solenoid 2, so that the joystick 1 is exposed from the main body 6.

With the above configuration, the operation of the electromagnetic solenoid 2 is controlled in conjunction with the opening and closing of the display 3, and the joystick 1 can be exposed from the main body 6 or retracted into the main body 6. Can be done.

In the above embodiment, the open/close state of the display 3 is detected by the limit switch 5, but as a modified example,
A light emitting diode and a photosensor may be used instead of the limit switch 5 to sense the open/closed state of the indicator 3. That is, when the display 3 is closed, light emitted from the light emitting diode is reflected by the display 3 (for example, reflected by the wall of the recess 8), and the reflected light is detected by the photosensor. Further, when the display device 3 is open, the emitted light is not reflected, so the light does not return to the photosensor. "1" corresponding to the presence or absence of light from this photosensor
By controlling the operation of the electromagnetic solenoid 2 with a pulse signal of "0", the same operation as described in the above embodiment can be obtained.

FIG. 3 is a schematic cross-sectional view showing a second embodiment of the electronic device according to the present invention. In the same figure, 11 is a roller, 12 is a lever, and 13 is a compression spring, and the reference numerals 11 to 13 are compression springs.
13 constitutes a control means. Further, in FIG. 3, parts that are the same as or equivalent to those in FIG.

In FIG. 3, the joystick 1 is rotatably connected to one end of a lever 12.
The rotation support part 14 is rotatably supported by the main body 6. Further, the roller 11 is attached to the bottom of the display 3 so as to be able to rotate integrally therewith.

As shown in FIG. 3, when the display 3 is closed, one end of the lever 12 is urged downward by the restoring force of the compression spring 13, so that the joystick 1 is moved inside the main body 6 (in the recess 10). will be stored in.

FIG. 4 is a schematic cross-sectional view showing the display device 3 in an open state in the second embodiment. When the display 3 is rotated from the closed state to the open state, the roller 11 also rotates together, and when the display 3 is rotated over a certain rotation angle (the display 3
(opens), the roller 11 rolls on the other end of the lever 12 and pushes it down. At this time, according to the principle of leverage, one end of the lever 12, which rotates around the rotary support section 14, moves upward, thereby causing the joystick 1 to move upward.

With the above configuration, the joystick 1 is housed inside the main body 6 when the display 3 is closed, and the joystick 1 is exposed from the main body 6 when the display 3 is opened. be able to.

FIG. 5 is a schematic cross-sectional view showing a third embodiment of the present invention. In the figure, 15 is a feed screw, 16 is a gear, 17 is an idler gear, 18 is a toothed portion formed at the bottom of the display 3, and numerals 15 to 18 constitute control means. In FIG. 5, the same parts or equivalent parts as in FIG. 3 are given the same reference numerals, and the explanation thereof will be omitted. The joystick 1 is attached to the feed screw 15.
When the joystick 1 rotates, the joystick 1 moves up and down. The feed screw 15 and the gear 16, the gear 16 and the idler gear 17, and the idler gear 17 and the toothed portion 18 mesh with each other to form a gear train.

Therefore, when the display 3 is rotated, the rotational force is transmitted through the gear train to rotate the feed screw 15 and move the joystick 1 up and down. In this embodiment, the joystick 1 is housed in the main body 6 when the display 3 is closed, and the joystick 1 is exposed from the main body 6 when the display 3 is opened.

[0021]

[Effects of the Invention] As explained above, the present invention is provided with a control means for exposing and retracting the joystick from the main body in accordance with the opening and closing of the display. Since the joystick can be exposed from the main body or stored in the main body, the joystick can be easily carried even if the joystick is mounted on a laptop-type electronic device. This also allows diagonal movement of the cursor on the screen.
