Abstract

(57) [Abstract] [Purpose] The operation of the key top on the printer control panel is changed to the vertical operation to further improve stability. [Structure] The frame 1 and the key top 2 are integrated, and an arm 3 from the frame 1 for holding the key top 2 is connected at two or more positions in a symmetrical position with the key top 2 as a center. Since the shape of S is S-shaped and has elasticity, the key top operation can be accurately performed in the vertical direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a printer device, and more particularly, to a key-top structure of an operation panel, which is frequently operated by users.

[0002]

[Prior Art]

 As a key top structure of a conventional printer operation panel, there is one shown in FIGS. 3 (a), 3 (b), 3 (c) and 3 (d). In the structure shown in FIGS. 3 (a) and 3 (b), the key top 2 is supported on the frame 1 by the two parallel arms 3 and 3 and has a key top structure in the same state as a cantilever. Was becoming. In the structure shown in FIGS. 3C and 3D, the key top 2 is configured as a separate part from the frame 1, and the key top 2 is sandwiched between the tact switch 4 and the frame of the hole 5 of the frame 1. It was supported in a locked-up state.

[0003]

[Problems to be solved by the device]

 Among the key top structures of the conventional printer operation panel shown in FIGS. 3 (a) and 3 (b), since the key top 2 is supported by the arm 3 in a cantilever manner, when the key top 2 is pressed down, Since the arm 3 is pushed along a circular orbit centered on the fulcrum of the arm 3 with the distance between the arm 3 and the key top 2 as a half diameter, it is pushed in a different direction with respect to the button operation of the tact switch 4. ..

For this reason, a click feeling cannot be obtained, or in the worst case, the switch cannot be pressed, and variations easily occur. In addition, the user's touch is not good because it does not move in the direction perpendicular to the operation panel surface.

Further, in the structure shown in FIGS. 3C and 3D, since the frame 1 and the key top 2 are separate parts, there is a problem that the parts cost is increased and the number of assembly steps is further increased. It was

An object of the present invention is to provide a key top structure of a printer operation panel that allows a switch to be clicked and to be surely pressed.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the key top structure of the printer operation panel according to the present invention is a key top structure provided in the printer operation panel, wherein the key top is provided on the frame through at least two or more arms. The arm is held in a symmetrical position about the key top and has a shape in which line segments having two or more directions such as an S shape are combined.

[0008]

[Action]

 The operation of the key tops on the printer control panel has been changed to vertical movement to improve stability.

[0009]

【Example】

 Next, the present invention will be described with reference to the drawings. FIG. 1A is a perspective view showing an embodiment of the present invention, FIG. 1B is an enlarged front view of a portion A of FIG. 1A, and FIG. 1C is a sectional view taken along the line AA ′ of FIG. Is.

In FIG. 1, a key top 2 is supported by a frame 1 by an arm 3, and the key top 2, the frame 1 and the arm 3 are integrally formed.

According to the shape of the key top 2, the arm 3 is placed at a position symmetrically holding the key top 2 so that the key top 2 moves vertically when the tact switch 4 is pressed down. It is provided in more than one place.

In this case, the arm 3 is not a straight line, but a combination of line segments having two or more directions, such as an S-shape, so that the arm 3 is extended when the key top 2 is pressed and moved.

FIG. 2 is an enlarged front view of a portion A when the number of arms 3 is changed according to the shape of the key top 2. When the shape of the key top 2 is large or irregular, the number of arms 3 may be increased in order to stabilize the operation of the key top.

[0014]

[Effect of the device]

 As described above, according to the present invention, the key top and the frame are held at the symmetrical positions with respect to the key top by the arm composed of a combination of line segments having two or more directions such as an S shape. , The operation of the key top is vertical, and the switch has a click feeling and can be pressed securely.

Further, since the key top and the frame are integrated parts, the cost of parts is only the frame, and the number of assembling steps can be reduced.
