Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a base member having a plurality of keys and a hole corresponding to the arrangement of the keys.
The present invention relates to a keyboard device provided with a keyboard cover for covering the protruding portions of the arranged keys, and a key storage portion provided on the keyboard cover and having a shape corresponding to the external shape of the keys for storing the keys. .

[0002]

2. Description of the Related Art Keyboard devices are used in various fields and are indispensable for OA equipment such as personal computers and word processors. It is also used in the field of photographic printing equipment. A keyboard cover is placed over the keyboard to prevent dust and liquid from entering the gap between the keys. The material of the keyboard cover is generally made of vinyl, so that the keys can be operated even when the cover is covered. FIG. 7 is a sectional view showing a state in which the keyboard cover 3 is covered. In FIG. 7, the left side is defined as the near side where the operator is located, and the right side in FIG. 7 is defined as the rear side. The front side 1a of the key 1 is a gentle slope, and the rear side 1b is a substantially vertical surface. A hole 2a is formed in the base member 2, and the key 1 protrudes from the hole 2a. Keyboard cover 3
Is formed with a key storage portion 3a, which is slightly larger than the outer shape of the key 1. The rear side wall surface 3b of the key storage portion 3a is located at a position close to the rear side 1b of the key 1,
Moreover, it is located at substantially the same position as the rear end face 2b of the hole 2a.

[0003]

FIG. 7B shows a state in which the key 1 is operated with the keyboard cover 3 covered. When the key 1 is pressed, the rear wall 3
b and the front wall surface 3c are deformed as shown in FIG. Since the front wall surface 3c is inclined, it does not get caught in the hole 2a, but the rear wall surface 3b is vertical and may be caught in the hole 2a when deformed. Then,
There is a problem that it becomes difficult for the storage portion 3a to return to the original state when the hand is released from the key 1. When the rear side wall surface was flat as shown in FIG. 7A, the touch when the key 1 was pressed was hard and heavy, and the touch was not good. This is the same for the left and right sides of the key storage section 3a.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to restore the key storage portion of a keyboard cover and operate the keyboard cover when operating keys while the keyboard cover is covered. An object of the present invention is to provide a keyboard device with improved feel.

[0005]

To achieve the above object, a keyboard device according to the present invention comprises: a plurality of keys; a base member having a hole corresponding to the arrangement of the keys; A keyboard cover that covers the protruding portion, and a key storage portion provided on the keyboard cover and having a shape corresponding to the outer shape of the key for storing the key, wherein a rear side of the storage portion is In order from the top of the key, a first wall is provided near the key, and a second wall is spaced apart from the key as compared to the first wall. The side end surface portion is disposed closer to the key than the second wall surface.

[0006] According to this configuration, the rear side of the storage section is not flat unlike the prior art, and the first wall surface and the second wall surface are stepped. Therefore, it is easy to deform,
The touch when pressing a key with the keyboard cover on is softened, and the operability is improved. Also, since the rear end surface of the key hole formed in the base member is closer to the key than the second wall surface, even if the second wall surface is deformed when the key is pressed. , It does not get caught in the hole. Therefore, the returnability of the key storage portion of the keyboard cover is improved. The left and / or right side of the key may have similar features.

[0007] Other features and advantages of the present invention will become apparent from the following description of embodiments with reference to the drawings.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS [Description of Embodiment Configuration] A keyboard device used in a photo printing device will be described. In FIG. 1, the lower side corresponds to the near side where the operator is located, and the upper side in FIG. 1 corresponds to the rear side. In FIG. 1, a plurality of correction keys N, H1, H2,... L1, L2... Having different correction input values for performing exposure amount correction and color correction are arranged on a base member 11 of the keyboard device 10. I have. On the keying surface of the correction key N located at the center of the correction key group, N indicating normal is displayed. Numerals +1 to +4 and -1 to -4 indicating the magnitude of the correction amount are displayed on the keying surface of the other correction keys. The correction key H5 has a numeral of + 5 / -4 displayed on the keying surface and is used when performing a correction of +5 or more and -4 or less. For example, the correction key H5 is pressed before the correction key H3 is pressed. And +8 can be corrected. The order key D is displayed on the keying surface as ODR, is used for distinguishing the order, and is pressed for each processing order of the negative film.

When the exposure amount is corrected, a correction value is input by appropriately pressing the correction keys N, H1 to H5, and L1 to L4. When color correction is performed, the function keys F4 to F6 (Y: yellow, M: magenta, C: cyan) are pressed to specify the color to be corrected, and then the correction keys N, H1 to H5, L1 to L4 Is pressed to input a correction value. Each correction key N, H1
H5, L1 to L4 are provided with light emitting diodes LED. Function keys indicated by F1 to F9 in the figure are arranged, and other cursor keys C1 to C4 are arranged. Holes 12 to 19 corresponding to the arrangements of the keys are formed in the base member 11.

[Structure of Keyboard Cover] FIG. 2 is a plan view of the keyboard cover 20, FIG.
FIG. 4 is a sectional view taken along line IV-IV of FIG. Keyboard cover 2
0 denotes a base 21 in contact with the base member 11 and a top 22
And an intermediate portion 23 having an intermediate height between the base portion 21 and the top portion 22.
4 are provided. As a material of the keyboard cover 20, a transparent PUR (polyurethane) is preferably used. The thickness is preferably about 0.2 mm. As shown in FIG. 3, the key storage portions 24 on the left and right sides of the key F1
It has a left first wall surface 24a and a right first wall surface 24b which are inclined in accordance with the shape of FIG. This is the same for other keys. Key F1 is located at the end, and key F1
On the left side of 1, not only the left first wall surface 24a but also a vertical left second wall surface 24c is formed. The key F
A space S1 is formed between 1 and the second left wall surface 24c. Further, the left end surface 11a of the base member 11 protrudes to a position closer to the key F1 than the second left wall surface 24c.

FIG. 4 shows the shapes of the keyboard covers 20 on the front side and the rear side of the key F2 (the same applies to other keys). The front wall surface 24d of the key storage portion 24 is a wall surface that is inclined according to the shape of the key F2. Further, a rear first wall surface 24e and a rear second wall surface 24f are provided on the rear side of the key F2 in order from the top of the key F2, and the rear first wall surface 24e is close to the key F2. But,
The rear second wall surface 24f is separated from the key F2, and a space S2 is formed between the rear second second wall surface 24f and the key F2. The rear end face 11b of the base member 11 is close to the key F2 as much as the rear first wall surface 24e.

[Explanation of Operation of Embodiment] FIG. 5 shows a state in which the key F2 is pressed with the keyboard cover 20 covered. Each wall 24 constituting the key storage unit 24
d, 24e and 24f are deformed, but the rear end face 11b
Is closer to the key F2 than the rear second wall surface 24f.
There is no saying that it gets caught.

[Modification] A modification of this embodiment will be described with reference to FIG. According to this, a rear third wall surface 24g is further formed on the rear side of the key F2. Needless to say, the object of the present invention can be achieved with such a configuration.
