Problems solved by technology

However, in this way, the light load when the panel member is initially pressed has no effect on information input, and information input is performed after applying a load within the range of a stable detection value, so prompt information input operation cannot be performed.

Embodiment approach 2

[0092] In Embodiment 1, a pair of electrodes 21a, 22a arranged between the first substrate 21 and the second substrate 22, and the pressure detection unit 23 with pressure-sensitive ink arranged between the pair of electrodes have been described. However, the pressure detection part 23 may also be formed in a structure in which a pair of electrodes is arranged on either the first substrate 21 or the second substrate 22, and the pressure detection part 23 is arranged on the first substrate or the second substrate in such a manner as to cover the pair of electrodes. the other side of the second substrate. In this way, since the electrode layer is one layer, the thickness of the pressure detection unit 23 is further reduced, and as a result, the pressure detection unit 20 can be reduced in thickness. In this case, a signal within a desired detection range can be obtained by forming a pair of electrodes in a comb shape, a spiral shape, or the like, and controlling the contact area...

Embodiment approach 3

[0094] like Figure 16 As shown, as the load transmitting portion 24 , a protrusion 24 a may be provided on the outer surface of the second substrate 22 . The installation area of ​​the protrusion 24a is formed to be smaller than the contact area between the pressure detection unit 23 and the second substrate 24a. When an external load is applied to the pressure detection part 23, the protrusion 24a supports the pressure detection part 23 from below, concentrates the load and transfers it to the pressure detection part 23 ( Figure 17 ). As the structure of the protrusion 24a, there is a structure in which a thermosetting resin or an ultraviolet curable resin is arranged and cured by printing or coating, a film or a resin plate that is cut out to match the size of the pressure detection part and pasted, PE Foams such as foam or urethane foam, adhesive adhesives or double-sided adhesive materials, double-sided tapes, and the like. The protrusion 24 a may be provided on the o...

Abstract

An information input device (1) is provided with a panel member (4) provided with a contact-type information input function; a package (2) having a support (2b) which supports the panel member (4); a pressure detection unit (5) provided over the panel member (4) and the support (2b) for detecting a pressing operation force against the panel member (4); and an initial load application unit (6) provided over the panel member (4) and the support (2b) for applying an initial load to the pressure detection unit (5) by drawing the panel member (4) and the support (2b), so that an information input operation corresponding to a pressing force against the panel member (4) can be quickly performed.

Description

technical field [0001] The present invention relates to an information input device capable of inputting information corresponding to the pressing force by a user's pressing operation on a panel member, and a pressure detection unit used in the information input device. Background technique [0002] As an information input device including a panel member having an information input function, a structure in which a touch panel is arranged on a liquid crystal display is widely used. In a digital camera having a liquid crystal monitor, there is a structure in which a panel member capable of detecting a contact position and a pressing force is provided on the upper surface of the liquid crystal monitor, and a different instruction is issued according to the pressing strength at the time of contact (for example, refer to Patent Document 1, Figure 22 ). [0003] In addition, in a display device of a car navigation device, a touch panel is provided on the surface of a liquid crys...
