  By the way, the structure which covers the peripheral part of the surface of a touch panel with a panel cover can be considered. In this configuration, it is important to manage the size of the gap between the touch panel and the panel cover. When the gap between the touch panel and the panel cover is large, there arises a problem that dust enters between the touch panel and the panel cover from the outside. On the other hand, if the gap between the touch panel and the panel cover is small, the surface of the touch panel is pressed by the panel cover, and an erroneous detection signal may be output from the touch panel.

  However, since the touch panel and the panel cover have dimensional errors, it is difficult to keep the dimension of the gap between the touch panel and the panel cover within an appropriate range.

  An object of the present invention is to provide an input display device capable of keeping the size of a gap between a touch panel and a cover provided in a display unit within an appropriate range.

  In order to achieve the above object, an input display device according to an aspect of the present invention includes a display unit including a touch panel having an operation surface to be touch-operated, a frame unit, and an opening formed by the frame unit. A cover disposed so that a part of the operation surface is exposed, and a biasing member that biases the display unit toward the cover, wherein the biasing member includes the operation surface of the display unit. A plate-like plate portion arranged at an interval with respect to the back surface on the opposite side, and extending in the first direction from the plate portion, with the display portion facing the cover at the tip portion in the first direction It has integrally the extending part to urge.

  According to this configuration, the display unit including the touch panel is urged toward the cover by the urging member. The urging member integrally has a plate portion and an extending portion. The plate portion is arranged with a space from the back surface opposite to the operation surface of the display portion. The extending part extends from the plate part in the first direction. The tip of the extension part urges the display part toward the cover.

  Due to the deformation of the extension part, each dimensional error of the display part and the cover can be absorbed. Therefore, the dimension of the gap between the touch panel and the cover can be within an appropriate range. As a result, dust can be prevented from entering between the touch panel and the cover. Moreover, it can suppress that the surface of a touchscreen is urged | biased by a cover.

  In the configuration in which the extension portion and the plate portion are separate, variation occurs in the force with which the tip portion of the extension portion biases the display portion due to an attachment error of the extension portion with respect to the plate portion. Since the extending portion is integrated with the plate portion, variation in the urging force due to such an attachment error can be suppressed. As a result, the dimension of the gap between the touch panel and the cover can be satisfactorily within the appropriate range.

  It is preferable that a concave portion into which the distal end portion of the extending portion enters is formed in the peripheral portion on the back surface of the display portion.

  According to this configuration, the distal end portion of the extending portion enters the recess, whereby the distal end portion of the extending portion can be brought into contact with a certain position on the back surface of the display unit. Moreover, when the front-end | tip part of an extension part urges | biases a display part, it can suppress that the front-end | tip part of an extension part moves on the back surface of a display part. As a result, the fixed position of the display unit can be stably urged by the distal end of the extending part.

  In general, the peripheral portion of the operation surface of the touch panel does not react to a press by an operator's finger or the like. Therefore, the peripheral part of the back surface of a display part is urged | biased by the front-end | tip part of an extension part, and the malfunctioning of the touch panel by the urging | biasing can be suppressed.

  It is preferable that the urging member is made of a sheet metal, and the extending portion elastically urges the display unit at the tip portion by the elasticity of the sheet metal.

  According to this configuration, each dimensional error of the display unit and the cover can be absorbed by the elastic deformation of the extending part.

  It is preferable that the base end part of the extension part in the first direction is formed wider than the tip part of the extension part in the second direction orthogonal to the first direction.

  Thereby, big intensity | strength can be given to the base end part of the extension part. As a result, it can suppress that the base end part of the extension part bends.

  It is preferable that the urging member is in non-contact with the back surface of the display unit in a normal state, and has a contact part that contacts the back surface of the display unit in a state where the display unit is bent and deformed.

  According to this configuration, when a large load is applied to the display unit and the display unit is bent and deformed, the back surface of the display unit is in contact with the contact unit, thereby suppressing the display unit from being further bent and deformed. it can.

  A plurality of contact portions may be provided. In this case, it is preferable that the contact portion is disposed to face the central portion of the back surface of the display portion and the peripheral portion thereof.

  According to this configuration, when a large load is applied to the central part of the display unit and the central part of the display unit is bent and deformed, the central part of the back surface of the display unit comes into contact with the contact part. Thereby, the further bending deformation of the center part of a display part can be suppressed. Further, when a large load is applied to the peripheral portion of the display unit and the peripheral portion of the display unit is bent and deformed, the peripheral portion on the back surface of the display unit contacts the contact portion. Thereby, the further bending deformation of the peripheral part of a display part can be suppressed. As a result, it is possible to suppress bending deformation in the entire area of the display unit.

  The urging member may have a locking portion and a screw insertion portion integrally with the plate portion. The locking portion is locked to the cover. A screw that is screwed into the cover is inserted into the screw insertion portion.

  According to this configuration, the urging member can be positioned with respect to the cover by the locking portion being locked to the cover. Then, the screw inserted through the screw insertion portion is screwed into the cover, whereby the urging member can be fixed in a state of being positioned with respect to the cover.

  The cover preferably has a positioning surface facing the display unit. On the other hand, it is preferable that the display unit includes a display panel that displays an image and a holding frame that holds the touch panel, and the holding frame has a positioning unit that comes into contact with the positioning surface.

  According to this configuration, since the positioning portion of the holding frame is brought into contact with the positioning surface of the cover, deformation of the cover due to the contact can be suppressed. Therefore, the dimension of the gap between the touch panel and the cover can be more satisfactorily within an appropriate range.

  An image processing apparatus according to another aspect of the present invention includes a main body and an input display device that is attached to the main body and displays and inputs information. The input display device is the above-described input display device.

  Therefore, this image processing apparatus can achieve the same operational effects as those described for the input display device.

  According to the present invention, the dimension of the gap between the touch panel and the cover can be within an appropriate range. As a result, dust can be prevented from entering between the touch panel and the cover. Moreover, it can suppress that the surface of a touchscreen is urged | biased by a cover.

<Effect>

  As described above, the display unit 305 including the touch panel 300 is urged toward the panel cover 20 by the urging member 303. The biasing member 303 has a plate portion 330 and an extension portion 360 integrally. The plate portion 330 is arranged with a space from the back surface of the display portion 305 opposite to the operation surface 307C. The extension part 360 extends from the plate part 330 in the AA-BB direction. The distal end portion 360 </ b> E of the extending portion 360 urges the display portion 305 toward the panel cover 20.

  Due to the deformation of the extending part 360, each dimensional error of the display part 305 and the panel cover 20 can be absorbed. Therefore, the dimension of the gap between the touch panel 300 and the panel cover 20 can be within an appropriate range. As a result, dust can be prevented from entering between the touch panel 300 and the panel cover 20. In addition, it is possible to suppress the surface of the touch panel 300 from being pressed by the panel cover 20.

  A configuration in which the extension part 360 and the plate part 330 are separated can be considered. However, due to an attachment error of the extension part 360 with respect to the plate part 330, variation occurs in the force with which the tip part 360E of the extension part 360 biases the display part 305. Since the extending portion 360 is integrated with the plate portion 330, variation in the urging force due to such an attachment error can be suppressed. As a result, the size of the gap between the touch panel 300 and the panel cover 20 can be satisfactorily within an appropriate range.

  A concave portion 326 into which the distal end portion 360E of the extending portion 360 enters is formed on the peripheral edge portion of the back surface of the display portion 305.

  According to this configuration, the distal end portion 360 </ b> E of the extending portion 360 enters the recessed portion 326, so that the distal end portion 360 </ b> E of the extending portion 360 can be brought into contact with a certain position on the back surface of the display unit 305. Further, when the distal end portion 360E of the extending portion 360 urges the display unit 305, it is possible to suppress the distal end portion 360E of the extending portion 360 from moving on the back surface of the display unit 305. As a result, the fixed position of the display unit 305 can be stably urged by the tip 360E of the extension 360.

  In general, the peripheral edge portion of the operation surface 307C of the touch panel 300 does not react to a press by an operator's finger or the like. Therefore, the malfunction of the touch panel 300 due to the biasing can be suppressed by biasing the peripheral edge portion of the back surface of the display unit 305 by the distal end portion 360E of the extending portion 360.

  The urging member 303 is made of a sheet metal, and the extending part 360 elastically urges the touch panel 300 with the tip part 360E due to the elasticity of the sheet metal.

  According to this configuration, the dimensional errors of the display unit 305 and the panel cover 20 can be absorbed by the elastic deformation of the extending part 360.

  The base end portion of the extension portion 360 is formed wider than the tip end portion 360E of the extension portion 360 in the EE-FF direction orthogonal to the AA-BB direction.

  As a result, the base end portion 360T of the extending portion 360 can be given high strength. As a result, the proximal end portion 360T of the extending portion 360 can be prevented from being bent.

  The biasing member 303 is not in contact with the back surface of the display unit 305 in a normal state, and the central contact portions 371, 372, 373, and 374 that contact the back surface of the display unit 305 in a state where the display unit 305 is bent and deformed, and Peripheral contact portions 375, 376, 377, and 378 are provided.

By abutting on 376, 377, and 378, the display unit 305 can be prevented from being further bent and deformed.

  The center contact portions 371, 372, 373, and 374 and the peripheral contact portions 375, 376, 377, and 378 are disposed to face the center portion of the back surface of the display unit 305 and the peripheral portion thereof.

  According to this configuration, when a large load is applied to the central part of the display unit 305 and the central part of the display unit 305 is bent and deformed, the central part of the back surface of the display unit 305 is the central contact part 371, 372, 373. 374 abuts. Thereby, the further bending deformation of the center part of the display part 305 can be suppressed. In addition, when a large load is applied to the periphery of the display unit 305 and the periphery of the display unit 305 is bent and deformed, the periphery of the back surface of the display unit 305 contacts the peripheral contact portions 375, 376, 377, and 378. . Thereby, the further bending deformation of the peripheral part of the display part 305 can be suppressed. As a result, bending deformation in the entire area of the display unit 305 can be suppressed.
