Description

  The present invention relates to an imaging device that improves the waterproof function of a pressure-sensitive touch panel provided in a display unit.

  Some digital still cameras have a touch panel display in which a touch panel is provided on the display surface of a display panel for displaying captured images. The touch panel display is used as an image display unit that displays a captured image, and also as an operation panel on which operation buttons and the like are displayed. By using such a touch panel display, the digital still camera can secure the size of the display surface of the image display unit while reducing the number of operation switches provided in the housing and reducing the size of the housing. .

  Examples of the touch panel constituting the touch panel display include a resistive film pressure-sensitive touch panel (hereinafter also simply referred to as a pressure-sensitive touch panel) such as a film-glass touch panel. In a pressure-sensitive touch panel, for example, two film substrates each having a transparent electrode provided on opposite surfaces are provided on a glass substrate, and a spacer is interposed between the two film substrates. Furthermore, the pressure-sensitive touch panel allows only light polarized in a specific direction to pass through the film substrate on the side opposite to the glass plate among these film substrates, as shown in FIG. A polarizing plate 100 is provided to prevent external light reflection from the light. As shown in FIG. 10A, the polarizing plate 100 includes a polarizer 100a formed by stretching PVA (Poly Vinyl Alcohol) impregnated with a pigment or iodine, and a TAC that protects the polarizer 100a. A (Tri Acetyl Cellulose) film 100b is sandwiched and bonded with an adhesive to be integrated.

Further, in the pressure-sensitive touch panel, as shown in FIG. 9A, an AR (Anti Reflection) film 101 for preventing reflection is adhered to the polarizing plate 100 with an optical glue 102. The AR film 101 is formed by coating a PET (Polyethylene Terephthalate) film with an inorganic dielectric such as SiO ₂ or TiO ₂ to form a plurality of films, and reflection of light incident from the surface due to the interference effect of the plurality of films. Reduce.

  In the pressure-sensitive touch panel as described above, when one film substrate is pressed with a finger or a dedicated touch pen, the transparent electrode of the one film substrate comes into contact with the transparent electrode of the other film substrate and is pressed. An operation signal is generated by detecting the coordinates. The pressure-sensitive touch panel outputs the generated operation signal to a control unit of a main board (not shown) built in the camera body via the flexible board.

  By the way, the digital still camera is sometimes used in a pool, the sea, a ski resort, or the like, and there is an increasing demand for waterproofing. Conventionally, a digital still camera is housed in a waterproof case in a place where the waterproof function as described above is required. However, storing the digital still camera in a waterproof case is troublesome and cumbersome, and also has problems such as being bulky.

  In the digital still camera, the surface of the polarizing plate 100 has high wettability due to the saponification treatment. Therefore, when the digital still camera is used in the place as described above, when water or the like enters the housing, water 103 enters the interface between the polarizing plate 100 and the optical glue 102 as shown in FIG. 9B. Then, there is a problem of peeling off. Further, in the digital still camera, the PVA of the polarizing plate 100 is water-soluble, and the wettability is increased by the saponification treatment of the TAC film 100b. Therefore, in the digital still camera, when water or the like enters the casing, water enters the interface between the polarizer 100a and the TAC film 100b as shown in FIG. It will be deformed.

  Therefore, in the information processing apparatus having the touch panel disclosed in Patent Document 1, the waterproof property is ensured by covering the opening surface of the front housing with a protective sheet provided on the touch panel. However, the information processing apparatus having the touch panel of Patent Document 1 requires a protective sheet for ensuring waterproofness on the touch panel, and increases the number of parts. In this information processing apparatus, the front casing, the protective sheet, and the support member are in close contact with each other, and there is a possibility that waterproofness cannot be maintained unless the front casing, the protection sheet, and the support member are flexible. Further, when the three parts are rigid bodies, they are easily peeled off by an external load.

  Moreover, in order to ensure the airtightness of the electronic device main body, the portable electronic device having the touch panel disclosed in Patent Document 2 uses a buffer having a U-shaped cross section so as to be in close contact with the touch panel and to be in close contact with the frame of the main body. I have to. However, in the portable electronic device having the touch panel of Patent Document 2, the buffer is further fitted together with the liquid crystal display panel, and the configuration is complicated. In particular, in order to ensure waterproofness, the probability of water leakage is high in a complicated structure.

  Furthermore, in an apparatus having a touch panel of Patent Document 3, a flexible member is sandwiched between internal components such as a liquid crystal panel and a touch panel and an exterior part to ensure waterproofness. However, in the apparatus having the touch panel of Patent Document 3, it is necessary to increase the interference of the flexible member, assuming that the gap between the internal component member and the exterior component becomes large. For this reason, a load is always applied to the exterior parts and the internal components, causing damage. Further, when the amount of interference of the flexible member is reduced, there is a possibility that airtightness cannot be ensured.
