Description

The present invention relates to a sheet type keyboard device used for inputting information and the like.

(Prior Art) Conventionally, a sheet type keyboard device used in this type of information input device has a structure as shown in FIG. 7 or FIG. That is, in ECR and the like, since the department key has a different key name depending on the user side, it is possible to easily change the key name on the user side or to convert each key sheet even if the program is changed.

In FIG. 7, reference numeral 31 denotes a keyboard body in which key switches are arranged in a matrix, and a sheet-like overlay 33 having transparent key portions 32 is placed on the surface thereof. 34 is a panel provided on the cover of the housing, and 35 is a key sheet in which key names are entered. When replacing the key sheets 35, first open the panel 34, then flip over the overlay 33 and then replace the key sheets 35 one by one.

FIG. 8 shows another conventional example, in which the overlay 33 'is entirely transparent so that the key sheet 35' can be exchanged when it is formed into a single sheet by key formatting. Others are 7th
Since it is similar to the conventional example shown in the figure, the description is omitted.

As described above, even the conventional seat type keyboard device can replace the seat key.

(Problems to be Solved by the Invention) In the conventional sheet type keyboard device described above, when replacing the key sheet, it is necessary to open and close the keyboard panel and repeat the operation of turning over the overlay, which is very troublesome. there were.

It is an object of the present invention to provide a seat type keyboard device which eliminates the drawbacks of the prior art and allows a key sheet to be easily replaced.

(Means for Solving Problems) A sheet-type keyboard device of the present invention is a key sheet in which a key name is entered corresponding to a key switch group and a positioning hole is formed at one end, and the key switch group. Is covered with a transparent sheet and has a slit hole for inserting the key sheet, and the rear surface of the overlay is arranged at a portion facing the key switch group and the opening end is connected to the slit hole. And a bag-shaped member for accommodating the key sheet inserted through the slit hole, and an end portion of the key sheet, which is provided outside the slit hole and is accommodated in the bag-shaped member, protruded from the slit hole. And a protrusion that fits into the positioning hole.

(Operation) According to the present invention, the bag-shaped member is arranged on the back surface of the overlay at a portion facing the key switch group, and the opening end thereof is connected to the slit hole, and the protrusion provided outside the slit hole is By fitting the key sheet housed in the bag-shaped member into the positioning hole at one end protruding from the slit hole, the key sheet can be inserted and set through the slit hole of the overlay, and the key sheet can be inserted without opening and closing the keyboard panel. It is possible to easily replace the key sheet, and it is possible to prevent the inserted and set key sheet from being displaced by a key operation or the like by being positioned at a predetermined position by the protrusion.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 6.

FIG. 1 is a perspective view of an information input device using the sheet type keyboard device of the present invention. In the figure, 1 is a sheet type keyboard device, 2 is a keyboard panel, 3 is a display, and 4 is a printer.

FIG. 2 is a plan view of the seat type keyboard device of the present invention. In the figure, 5 is a function key, 6 is an operation key, 7 is a ten-key, and 8 is a department key. 9
Is an overlay, and the section key 8 is transparent. As the overlay 9, a transparent or translucent vinyl chloride sheet, a polyester film sheet, a polycarbonate sheet, or the like is used.

FIG. 3 is a plan view of a key sheet to be inserted and set in the sheet type keyboard device of the present invention. In the figure, reference numeral 10 is a key sheet in which a key name can be entered, which is key-formatted so as to represent the shape 11 of the key, and is made of a thick or synthetic paper material which is easy to enter with a pencil or a ballpoint pen. 12 is a locking pin that is a protrusion, and the key sheet 10
The tongue piece 13 is fitted in a hole 14 provided as a positioning hole.

4 and 5 are partial cross-sectional views of the seat type keyboard device shown in FIG. 2, and FIG. 6 is a perspective view of a bag-like sheet in a pocket of the seat type keyboard device of the present invention.

In the figure, numeral 15 is an elastic sheet such as rubber or sponge, which constitutes a keyboard sheet 16 attached to the back surface of the overlay 9. Reference numeral 17 is a group of key switches arranged in a matrix, which is soldered onto a printed circuit board 18 and fixed to a frame body 19 made of a frame metal. The head surface 20 of the key switch group 17 constitutes a keyboard 22 aligned with the surface 21 of the frame body 19. keyboard
The keyboard sheet 16 is attached to the surface of 22. Note that the head switch 20 of the key switch group 17 is stuck and not fixed because the key switches move up and down. Reference numeral 23 is a thin sheet having a bag shape with one side opened, and the overlay 9 is sandwiched between the elastic sheet 15 and a pocket 25 connected to a slit hole 24 formed in the overlay 9. The bag-shaped sheet 23 is formed of a sheet thinner than the overlay 9. The width L of the slit hole 24 is slightly wider than the width l of the key sheet 10, and is dimensioned so that when the key sheet 10 is inserted and set, there is no rattling to the left and right with respect to the insertion direction. .

When the key sheet 10 is set, as shown in FIGS. 4 and 5, the pocket 25 formed by the bag-like sheet 23 connected to the slit hole 24 provided in the overlay 9 is slanted as shown by an arrow. You can insert and set it in place by pushing from. At this time, the key sheet 10 has the tongue piece 13 protruding outward from the slit hole 24, and the locking pin 12 is fitted into the hole 14 provided in the tongue piece 13 to position the key sheet 10. Lock with. The locking pin 12 also serves to prevent the key 9 from being displaced when it is pushed from above the overlay 9 by a key operation after the key sheet 10 is set.

As described above, according to the above-described embodiment, since the bag-shaped sheet 23 is formed between the overlay 9 and the pocket 25 to sandwich the bag-shaped sheet 23, the key sheet 10 is directly attached to the lower portion of the overlay 9 without opening and closing the keyboard panel. Can be easily inserted and set. Also, the user can freely exchange the key sheet.

(Effect of the Invention) According to the present invention, when the key sheet is replaced as in the conventional case, the operation case is compared with the case where the keyboard panel of the case is first opened and closed and then the overlay is turned over. The structure is simple, and even if the key sheet is suddenly replaced during operation, the user can easily do it in a short time. Further, in the key sheet housed in the bag-shaped member, one end portion in which the positioning hole is bored protrudes from the slit hole, and the protrusion provided on the outside of the slit hole protrudes from the bag-shaped member. By fitting into the positioning hole at one end, even if there is play between the bag-shaped member and the tip of the key sheet, the key sheet can be positioned with high accuracy by the protrusion, and the key sheet can be positioned through the slit hole. Since one end of the projected key sheet functions as a handle that can be gripped by the user, it is possible to facilitate the work of separating the positioning hole from the protrusion and the work of inserting / discharging the key sheet into / from the bag-shaped member. it can. In addition, the equipment can be downsized, and the practical effect is great.
