Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a key sheet to be mounted on a keyboard.

2. Description of the Related Art For example, in an input device for registering sales data such as an electronic scale, a unit price is set in advance for each product name using a keyboard, and then the unit price for each product name is called by the keyboard to calculate the sales price. You have registered sales data. In order to set the unit price etc. and to register sales data as a normal operation using the same keyboard, set the setting key pattern sheet with many setting key names and this setting key pattern sheet. Attach a setting key sheet that has a transparent protective sheet covering it and an opening on at least one side of the both sides, and glues the other side in a bag shape on the keyboard.When setting the unit price, etc., from the top of the setting key sheet When operating the keys on the keyboard and registering after setting, insert a regular key pattern sheet with many regular key names displayed between the setting key pattern sheet and the protective sheet, and display this regular key sheet. There is a usage pattern in which a key is operated according to an item.

Problems to be solved by the invention The regular key sheet is used to write commonly used items such as a product name according to the purpose of use of the user, but since the written characters are reflected on the inner surface of the protective sheet, the protective sheet becomes dirty. On the other hand, the setting key pattern sheet has constant setting items and is always attached to the keyboard. As a result, the display content of the setting key pattern sheet becomes difficult to see due to the frequent insertion and removal of the regular key pattern sheet.

Means for Solving the Problem For setting that is attached on the keyboard by fixing the setting key pattern sheet on which the setting key name is displayed and the transparent protective sheet that covers the setting key pattern sheet in a bag shape. A key sheet is provided, and a regular key pattern sheet having a regular key name displayed is detachably provided between the setting key pattern sheet and the protective sheet of the setting key sheet, and the surface of the regular key pattern sheet A transparent protective sheet for covering at least one side was fixed to the regular key pattern sheet.

When setting action data, operate the keys according to the display on the setting key sheet without inserting the regular key sheet. In the normal usage after setting, the regular key sheet is inserted under the protective sheet of the setting key sheet. In this case, since the regular key sheet has the protective sheet, it is possible to reliably prevent the characters written on the regular key pattern sheet from appearing on the protective sheet of the setting key sheet.

Embodiment An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of the setting key sheet 1 and the regular key sheet 9. The setting key sheet 1 includes a synthetic resin setting key pattern sheet 3 on which a setting key name 2 is displayed and a transparent synthetic resin protective sheet 4 covering the setting key pattern sheet 3 on three sides. It is formed by welding 5,6,7 in a bag shape. However, an unfixed portion 8 that is not welded is formed on a part of the side 6 at three locations on both sides and the center. Further, the regular key sheet 9 includes a regular key pattern sheet 11 made of synthetic resin in which a key name 10 such as a commonly used product name is written, and the regular key pattern sheet 11
And a protective sheet 12 made of a transparent synthetic resin for covering. A tab 14 is integrally formed on one side 13 of the regular key pattern sheet 11 and the protective sheet 12, and a plurality of tongues are welded to each other on the opposite side 15 and inserted into the unfixed portion 8. The piece 16 is integrally formed. Further, a release sheet 19 is laminated on the adhesive surface formed on the back surface of the setting key pattern sheet 3.

FIG. 2 is a perspective view of the setting key sheet 1 and the regular key sheet 9. An opening 17 for inserting and removing the regular key sheet 9 is formed on one side of the setting key sheet 1. Then, in order to make it easier to open the opening 17, the protective sheet 4
A slit-shaped notch 18 is formed on both sides of the slit.

FIG. 3 is a vertical cross-sectional view of a part of a state in which the setting key sheet 1 is adhered to the keyboard 20. In the setting key sheet 1, the release sheet 19 is peeled off and the back side adhesive surface is adhered to the upper surface of the key 21. It is fixed by. The setting key pattern sheet 3 is integrally formed with a protrusion 22 that projects toward the center of each key 21. The keyboard 20
Is a keyboard of the electronic scale shown in FIG.

In such a configuration, when setting data such as a unit price, the setting key sheet 1 is set without inserting the regular key sheet 9.
The key 21 is operated according to the key name 2 of. In the normal usage after setting, the regular key sheet 9 is inserted from the opening 17 of the setting key sheet 1 to the lower side of the protective sheet 4. In this case, since the regular key sheet 9 has the protective sheet 12, the characters written as the key name 10 on the regular key pattern sheet 11 are reliably prevented from appearing on the protective sheet 4 of the setting key sheet 1. be able to. As a result, unlike the regular key sheet 9 that is rewritten according to the purpose of use, the setting key sheet 1 is always attached to the keyboard 20, but the protective sheet 12 can be used in a long-term, easy-to-see state without being contaminated. .

In addition, since the protrusion 22 that comes into contact with the center of the key 21 is formed on the back surface of the setting key pattern sheet 3, even if the position of the finger pressing the key 21 deviates from the center of the key 21, the pressure from the finger will be the protrusion 22. It is easy to act on the contact area between the key and the key 21. As a result, it is possible to prevent an operation error of the key 21.

Further, the setting key sheet 1 is formed by welding the setting key pattern sheet 3 and the protective sheet 4, and the regular key sheet 1 is formed by welding the tongue piece 16 of the regular key pattern sheet 11 and the protective sheet 12. Although formed, the tongue piece 16 is inserted into the unfixed portion 8, so that the regular key sheet 9 can be inserted and removed even if the welding margin of the setting key sheet 1 and the welding margin of the regular key sheet 9 are overlapped. As a result, the space for the welding margin of both key sheets 1 and 9 can be reduced.

Effect of the Invention Since the present invention is configured as described above, the normal key sheet is inserted under the protective sheet of the setting key sheet for normal key operation after setting, but the regular key sheet does not have the protective sheet. Since it has, the characters written on the regular key pattern sheet do not appear on the protective sheet of the setting key sheet, which allows the setting key sheet to be used for a long time in an easy-to-see state. Have.
