KEY SHEET
First Claim
1. A key sheet, which comprises:
- an operation member having a plurality of depressing operation portions on a sliding operation surface on which a user performs sliding input operation; and
a sensor sheet for sensing the sliding input operation of the user as a change in capacitance,further comprising a fixation layer provided below the plurality of depressing operation portions and existing between the operation member and the sensor sheet to form a laminate structure devoid of a gap in a direction perpendicular to a plane of the sliding operation surface,wherein the operation member has, at adjacent positions between the plurality of depressing operation portions, a movable contact portion which enters a gap devoid of a fixation layer between the operation member and the sensor sheet through sliding operation of the user and which is displaced so as to be capable of coming into contact with the sensor sheet.

Abstract
Provided is a key sheet allowing reliable sliding operation input through accurate coordinate position detection and depressing operation input of satisfactory depression operability through clear click feel. Fixation layers are formed at positions under depressing operation portions, and there are no fixation layers in portions around the depressing operation portions but gaps are formed. With this construction, it is possible to suppress a depression operation load to a low level at a time of depressing input operation, and, when contact switches with click feel are depressed, the click feel can be easily transmitted. Further, a surface sheet has movable contact portions which enter the gaps at a time of sliding input operation and which are displaced so as to be capable of coming into contact with a sensor sheet. With this construction, it is possible to sense, in a stable manner, capacitance at an in-plane position of a sliding operation surface of the sensor sheet.
