Description

[Detailed description of the invention] Regarding the sheet attaching/detaching device of the present invention that is easy to attach and detach, the object is to provide a structure that facilitates positioning and detachment of page sheets, especially for keyboard input devices of page sheet exchange type. It is something.

A keyboard input device that is one of the computer input devices
There is one that uses a page sheet exchange method.

This allows the meaning of each key on the keyboard to be changed arbitrarily depending on the purpose of use, and a sheet with the desired key arrangement is placed on top of the main body, which has a large number of key switches arranged on a flat surface. By operating another switch that specifies the type of sheet, it can be used as a keyboard with the key arrangement written on the sheet.

In such a keyboard, if the seat and main body are not positioned correctly, the key tops placed on the seat will not correspond to the actual key switches on the main body, leading to incorrect operation.

It is also desirable that the old sheet be easily removed when replacing the sheet, and that the new sheet be installed and positioned accurately and quickly.

Conventionally, positioning has been done by drilling holes in the sheet and placing guide pins on the main body side, simply holding it down with a clip-type or leaf spring-type holding plate, or using a combination of both. This also has the disadvantage that the sheet adheres closely to the main body, making it troublesome to turn it up, especially when removing the sheet.

The present invention eliminates the drawbacks of the conventional example, and one embodiment of the present invention will be explained in detail below with reference to the drawings.

FIG. 1 is an external view of one embodiment of a computer terminal device to which the present invention is applied.

1 is a keyboard input device body, 2 is a display device,
11 is a group of key switches on the main body 1, 12 is a group of switches for setting the type of seat, and 13 is a seat attachment/detachment device.

A seat (not shown) is placed on the switch group 11 and fixed by an attachment/detachment device 13.

FIG. 2 is a sectional view of the main body 1, and 13 is a holding plate;
13a is a sheet holding portion formed at one end of the sheet 3, which presses and clamps the sheet 3 against the main body 1 at the arrow A section.

The pressing is done by the spring force of the spring 11. A rotating shaft 15 is provided near the center of the holding plate 13, and both ends of the shaft 15 are connected to the main body 1.
It is pivoted on.

The feature of the present invention is a member 16 provided on the back of the presser plate 13, and this member 16 has a groove 16a at a position corresponding to the back of the sheet presser part 13a of the presser plate 13.
It is rotatable about one shaft 15 together with the bonito presser plate 13.

As shown in the figure, the sheet 3 is inserted into the groove 16a of the member 16 and is held between the sheet 3 and the main body 1 by the sheet holding portion 13a.

The seat can be positioned by making the depth of the groove 16a constant and by inserting the sheet 3 at the casing that hits the bottom of the groove.

The state in which the upper end of the presser plate 13 is pressed is shown in FIG. 3a.

Shown in b.

By pushing the upper end against the spring force, the holding plate 13 and the member 16 are rotated clockwise in the figure around the shaft 15, the sheet holding part 13a is separated from the main body side, and the seat 3 is released.

At this time, since the end of the sheet 3 is the trench 1 inserted into the groove 16a of the member 16, the sheet 3 is lifted up in a mountainous manner due to its rigidity as shown in the figure.

Due to this action, the seat 3 can be easily grasped by inserting one's fingers into the space created at the bottom of the seat, and the seat 3 can be removed extremely easily.

Note that the member 16 may be provided on the entire back surface of the holding plate 13, or may be provided only on both left and right ends.

The housing holding plate 13 and the member 16 may be fixed with screws or adhesive, but by passing the shaft 15 through them as shown in the figure, both can rotate together without any particular fixing means.

Furthermore, instead of creating the holding plate 13 and the member 16 separately as in the above-described actual case (FIG. 4a), it is also possible to construct them integrally from the beginning by extrusion molding of aluminum or the like (FIG. 4b).

Furthermore, the present invention is not limited to computer keyboard input devices;
It can also be applied to any purpose of attaching and detaching a sheet on the skin, such as attaching and detaching a score sheet for a polling game.

Note that the seat 3 is sometimes installed using the seat holding part 13a.
Since the tip of the sheet is slightly turned up, if the sheet has a certain degree of rigidity, it is only necessary to push the sheet 3 between the main body 1 and the sheet holding part.

As described above, the present invention has a groove 1 into which the sheet 3 is inserted and held.
6a, the sheet automatically lifts up and can be easily removed when removed, greatly improving operability and having great effects.

Claims (1)

[Scope of utility model registration request] It has a main body 1 on which a sheet is placed, and a holding plate 13,
A sheet holding portion 13a is formed at one end of the holding plate and is constantly pressed toward the main body by a spring force, and near the center of the holding plate there is a rotating shaft 15 that is pivotally supported by the main body. In a seat attachment/detachment device configured such that the sheet holding part moves away from the main body side against the spring force to release the seat by pushing the other end, the end of the sheet can be inserted into the back of the sheet holding part. A sheet attaching/detaching device characterized in that a member 16 having a groove 16a is provided so as to be rotatable integrally with the presser plate.
