Description

  The present invention relates to an electronic apparatus including a display unit that displays file objects.

  Conventionally, when an arbitrary file is updated in an electronic device such as a personal computer or a smartphone, the original file is overwritten using the same file name. With this overwriting and updating method, it is not possible to return to the past (original) file after the update. Therefore, when updating an arbitrary file, in order to save a past file, the file may be copied to create a save file and an update file.

  As a conventional technique, there has been proposed a file management system that prevents information on an original file from being accidentally deleted by an operation such as overwriting (see, for example, Patent Document 1).

FIG. 1 is a block diagram showing a schematic configuration of an electronic apparatus according to an embodiment of the present invention. As shown in FIG. 1, the electronic device 1 includes a contact detection unit (touch panel) 10, a display unit 20, a load detection unit 30, a storage unit 40, a tactile sensation providing unit 50, and a control unit 60.

  The display unit 20 displays an object such as an icon representing a file as an image. An operator touches (touches) this object with a contact object such as a finger or a stylus pen, and manipulates the file by dragging or the like (for example, moving, opening, joining, etc.) Can do. The display unit 20 is configured using, for example, a liquid crystal display panel (LCD), an organic EL display panel, or the like.

  The contact detection unit (touch panel) 10 is normally arranged on the front surface of the display unit 20 and is contacted with a contact object (pressed object) such as an operator's finger on the object displayed on the display unit 20 or released from the contact. It detects on the input surface 10a of the corresponding contact detection part 10. FIG. Further, the contact detection unit 10 detects a contact position with respect to the input surface 10 a and notifies the control unit 60 of the detected contact position. The contact detection unit 10 is configured by a known method such as a resistance film method or a capacitance method. In addition, when the contact detection part (touch panel) 10 detects the contact by a contact thing, it is not essential that a contact thing touches the contact detection part 10 physically. For example, when the contact detection unit 10 is optical, the contact detection unit 10 detects a position where infrared rays or the like on the contact detection unit 10 is blocked by the contact object, so that the contact object touches the contact detection unit 10. It is not necessary.

  The load detection unit 30 detects a pressing load on the input surface 10a of the contact detection unit 10, and is configured using an element such as a strain gauge sensor or a piezoelectric element, for example. In addition, the load detection unit 30 notifies the control unit 60 of the detected pressing load on the input surface 10a.

  Based on the contact position of the contact object in the area of the contact detection unit 10 corresponding to the display area of the object displayed on the display unit 20 and the pressing load detected by the load detection unit 30, the control unit 60 Perform the operation. When the pressing load acquired from the load detection unit 30 satisfies a predetermined load standard stored in the storage unit 40, the tactile sensation providing unit 50 is instructed to perform a tactile sensation providing operation.

  In addition, the control unit 60 detects that the pressing load detected by the load detection unit 30 is in a state where the contact position of the contact object detected by the contact detection unit 10 is changed to the position of the display area of another object by dragging the object. If the predetermined load criterion is satisfied, a file consisting of the common data of the dragged object file and the other object file is created, and if the load criterion different from the predetermined load criterion is satisfied, 2 Create a file that contains all the data from one file.

  The tactile sensation providing unit 50 is configured using, for example, a piezoelectric vibrator or the like, and presents a predetermined tactile sensation to a contact object that is in contact with the input surface 10a by generating vibration according to a predetermined vibration pattern. . The tactile sensation providing unit 50 can notify the operator whether or not the pressing load satisfies the load standard.

  The storage unit 40 can be configured by a memory according to a known technique, and stores various input information, a program for operating the electronic device 1, and the like, and also functions as a work memory. In particular, in the present embodiment, the control unit 60 uses the first to fourth load reference values used when creating various files according to the pressing load acquired from the load detection unit 30, and each object. And a display area corresponding to. Here, for the first to fourth load reference values, the second load reference value is larger (higher) than the first load reference value, and the third load reference value is the second load reference value. It is assumed that the value of the fourth load standard is larger than the value of the third load standard.

  2A and 2B show an example of a mounting structure of the electronic device 1 shown in FIG. 1, in which FIG. 2A is a main part sectional view and FIG. 2B is a main part plan view. The display unit 20 is housed and held in the housing 11. The contact detection unit 10 is held on the display unit 20 via an insulator 12 made of an elastic member. In electronic device 1 according to the present embodiment, display unit 20 and contact detection unit 10 have a rectangular shape in plan view. In the present embodiment, the contact detection unit 10 is held on the display unit 20 via the insulators 12 disposed at the four corners deviated from the display area A of the display unit 20 indicated by phantom lines in FIG. .

  Further, the housing 11 is provided with an upper cover 13 so as to cover the surface area of the contact detection unit 10 deviated from the display area of the display unit 20, and an elastic member is provided between the upper cover 13 and the contact detection unit 10. An insulator 14 comprising:

  In addition, the contact detection part 10 shown in FIG. 2 comprises the surface member which has the input surface 10a, for example by the transparent film or glass, and comprises the back surface member by glass or acrylic. The contact detection unit 10 uses a structure in which, when the input surface 10a is pressed, the pressed portion is slightly bent (distorted) according to the pressing force, or the structure itself is bent slightly.

  On the surface of the contact detection unit 10, a strain gauge sensor 31 for detecting a load (pressing force) applied to the contact detection unit 10 is provided in the vicinity of each side covered with the upper cover 13 by bonding or the like. In addition, on the back surface of the contact detection unit 10, a piezoelectric vibrator 51 for vibrating the contact detection unit 10 is provided in the vicinity of two opposing sides by bonding or the like. That is, in the electronic device 1 shown in FIG. 2, the load detection unit 30 shown in FIG. 1 is configured using four strain gauge sensors 31, and the tactile sensation providing unit 50 is configured using two piezoelectric vibrators 51. Yes. And the input surface 10a is vibrated by vibrating the contact detection part 10 by the tactile sense presentation part 50. FIG. In FIG. 2B, the casing 11, the upper cover 13, and the insulator 14 shown in FIG. 2A are not shown.

  Next, the operation of the electronic apparatus 1 according to this embodiment configured as described above will be described. FIG. 3 is a flowchart illustrating the operation of the electronic device 1 according to the present embodiment, and FIG. 4 is a diagram schematically illustrating the operation of the electronic device 1 according to the present embodiment. On the display unit 20, icons (objects) 2 and 3 of two files having the same attribute (for example, extension) are displayed, and the contents of the file related to the icon 2 are configured by A + B. It is assumed that the content of the file related to the icon 3 is composed of A + C. Here, it is assumed that the last (latest) update date of the file related to the icon 2 is before the last update date of the file related to the icon 3.

  First, when the operation of the electronic device 1 starts, the control unit 60 monitors contact with the contact detection unit 10 (step S101). In step S101, when contact with the contact detection unit 10 by a contact object such as an operator's finger is detected, the control unit 60 acquires a contact position from the contact detection unit 10 (step S102).

  The control unit 60 determines whether or not the contact position acquired in step S102 corresponds to the position where the icon 2 is displayed (step S103). If the contact position does not correspond to the position where the icon 2 is displayed, the process ends. On the other hand, as shown in FIG. 4A, when the contact position corresponds to the position where the icon 2 is displayed, the control unit 60 further monitors the contact with the contact detection unit 10, and the contact detection unit 10. It is determined whether or not the contact position has moved to the position where the icon 3 is displayed in a state where the icon 2 is touched, that is, whether or not the icon 2 is overlapped with the icon 3 by dragging the icon 2 (step S104). FIG. 4B shows a state when the icon 2 is about to contact the icon 3, and FIG. 4C shows a state immediately before the icon 2 and the icon 3 overlap each other. When the icons 2 and 3 are not overlapped (No in step S104), the control unit 60 determines whether or not the contact detection unit 10 has detected release (non-contact) (step S120). If the contact detection unit 10 detects release (Yes in step S120), the control unit 60 ends the process. When the contact detection unit 10 does not detect release (No in step S120), the process returns to step S104. If the icons 2 and 3 overlap (Yes in step S104), it is determined whether or not the attribute of the file of icon 2 matches the attribute of the file of icon 3 (step S105). If the file attributes do not match, the process proceeds to another process (step S106).

  If the file attributes match, the control unit 60 determines whether or not the load detection unit 30 has detected a pressing load equal to or greater than the first load reference (step S107). When the pressing load detected by the load detection unit 30 is less than the first load reference (No in step S107), the control unit 60 determines whether the contact detection unit 10 has detected release (non-contact). (Step S108). When the contact detection unit 10 detects release (Yes in step S108), the control unit 60 merges (combines) the contents of the files indicated by the two icons 2 and 3 as shown in FIG. ) To create a file whose file content is A + B + C (step S118). The icons 2 and 3 are combined to display the icon 4 (step S119). If the contact detection unit 10 does not detect release (No in step S108), the process returns to step S107.

  In step S107, when the load detection unit 30 detects a pressing load equal to or greater than the first load reference (in the case of Yes), the control unit 60 instructs the tactile sensation providing unit 50 to perform a tactile sensation providing operation. After that, it is determined whether or not the load detection unit 30 has detected a pressing load equal to or higher than the second load reference (step S109). When the pressing load detected by the load detection unit 30 is less than the second load reference (No in step S109), the control unit 60 determines whether the contact detection unit 10 has detected release (step S110). ). When the contact detection unit 10 detects the release (Yes in step S110), the control unit 60 creates a file with the contents of A that includes the common data portion of the files indicated by the two icons 2 and 3 ( Step S111). FIG. 4E shows a state in which a file having the contents A is created, and also shows a correspondence relationship between the first load standard and the file contents A. The icons 2 and 3 are combined to display the icon 4 (step S119). When the contact detection unit 10 does not detect release (No in step S110), the process returns to step S109.

  In step S109, when the load detection unit 30 detects a pressing load equal to or higher than the second load reference (in the case of Yes), the control unit 60 instructs the tactile sensation providing unit 50 to perform a tactile sensation providing operation. Then, it is determined whether or not the load detection unit 30 has detected a pressing load equal to or greater than the third load reference (step S112). When the pressing load detected by the load detection unit 30 is less than the third load reference (No in step S112), the control unit 60 determines whether the contact detection unit 10 has detected release (step S113). ). When the contact detection unit 10 detects release (Yes in step S113), the control unit 60 creates an A + B file that is the content of the file indicated by the icon 2 (step S114). FIG. 4E shows a state in which a file having the contents of A + B has been created, and shows a correspondence relationship between the second load standard and the file contents A + B. The icons 2 and 3 are combined to display the icon 4 (step S119). If the contact detection unit 10 does not detect release (No in step S113), the process returns to step S112.

  In step S112, when the load detection unit 30 detects a pressing load equal to or greater than the third load reference (Yes), the control unit 60 instructs the tactile sensation providing unit 50 to perform a tactile sensation providing operation. Then, it is determined whether or not the load detection unit 30 has detected a pressing load equal to or greater than the fourth load reference (step S115). When the pressing load detected by the load detection unit 30 is less than the fourth load reference (No in step S115), the control unit 60 determines whether the contact detection unit 10 has detected release (step S116). ). When the contact detection unit 10 detects release (Yes in step S116), the control unit 60 creates an A + C file that is the content of the file indicated by the icon 3 (step S117). FIG. 4E shows a state in which a file having the contents of A + C has been created, and shows a correspondence relationship between the third load standard and the file contents A + C. The icons 2 and 3 are combined to display the icon 4 (step S119). When the contact detection unit 10 does not detect release (No in step S113), the process returns to step S115.

  In step S115, when the load detection unit 30 detects a pressing load equal to or higher than the fourth load reference (in the case of Yes), the control unit 60, as shown in FIG. The file contents indicated by 3 are merged to create a file whose file contents are A + B + C (step S118). The icons 2 and 3 are combined to display the icon 4 (step S119).

  As described above, in the electronic device according to the present embodiment, if an object is dragged and superimposed on another object, the file of the dragged object and the file composed of common data of the other object files Or a file including all data of two files can be created, so that the contents of the file can be quickly and easily integrated with the contents desired by the user.

  In addition, this invention is not limited only to embodiment mentioned above, Many deformation | transformation or a change is possible. For example, in the above-described embodiment, the load detection unit 30 is provided, and the object file operation is performed based on the pressing load detected by the load detection unit 30, but the present invention includes the load detection unit 30. The control unit 60 includes a display unit 20 that displays an object, a contact detection unit 10 that detects contact of a contact object, and a control unit 60 that operates an object file displayed on the display unit 20. If the object is dragged and the contact position of the contact detected by the contact detector 10 changes to the position of the display area of the other object, the file of the dragged object and the common file of the other object Create a file consisting of data, or create a file that contains all the data of two files, Yl operate may be performed.

  Further, the present invention further includes a display unit 20 that displays an object and a control unit 60 that operates a file of the object displayed on the display unit 20 without including the contact detection unit 10. If an object is dragged with the mouse or the like and superimposed on another object, create a file consisting of the dragged object file and the common data of the other object files, or Object file operations may be performed by creating a file including all data.

  In the above-described embodiment, the first to fourth load reference values are stored in the storage unit 60. However, the first to fourth load reference values are appropriately changed by the operator. It may be a thing.

  In the above-described embodiments, for example, the expression “above” or “less than” the load standard is not necessarily a strict meaning, and the term “more than” the load standard may include a case where the load exceeds the standard load. The load standard “less than” can include a case where the load is equal to or less than the standard load.

  Further, in the above-described embodiment, the contact detection unit 10 is used to detect contact with the input surface 10a. However, when the load sensor (load detection unit) is used to satisfy a predetermined pressing load standard, the contact is detected. It can also be determined that it has been done. Such a load detection unit can be configured using an arbitrary number of strain gauge sensors 31 and the like, similarly to the load detection unit 30 of the above-described embodiment.

  Moreover, the tactile sensation providing unit 50 can be configured to indirectly vibrate the input surface 10a of the contact detection unit 10 by vibrating the electronic device 1 based on a vibration motor (eccentric motor). Furthermore, when the load detection unit 30 and the tactile sensation presentation unit 50 are configured using piezoelectric elements, the load detection unit 30 and the tactile sensation presentation unit 50 can also be configured by sharing the piezoelectric elements. This is because the piezoelectric element generates electric power (voltage) when pressure is applied and deforms when electric power (voltage) is applied.

  In the above-described embodiment, the description has been made assuming the configuration in which the contact detection unit 10 is disposed so as to overlap the upper surface of the display unit 20, but such a configuration is not necessarily required, and the contact detection unit 10 and the display unit 20 are not necessarily provided. May be separated from each other.

  Further, in the above-described embodiment, as an aspect in which the tactile sensation providing unit 50 presents a tactile sensation to the contact target that is in contact with the input surface 10a, the tactile sensation providing unit 50 generates vibrations on the input surface 10a, so that the input is performed. Although described with reference to an embodiment of presenting a tactile sensation with respect to a contact target that is in contact with the surface 10a, the present invention is not limited to this, by controlling the charge of the film pasted on the contact detection unit 10, etc. You may show a tactile sensation with respect to the contact target which is contacting the input surface 10a, without using mechanical vibration.

  Further, the contact detection unit 10 and the display unit 20 in the description of the above-described embodiment of the present invention are configured by an integrated device by providing both functions of the contact detection unit 10 and the display unit 20 on a common substrate. May be. As an example of the configuration of the device in which both functions of the contact detection unit 10 and the display unit 20 are integrated, a plurality of photoelectric conversion elements such as photodiodes are regularly arranged in a matrix electrode array of pixels included in a liquid crystal panel. Some are mixed. This device displays an image with a liquid crystal panel structure, while reflecting the light of a backlight for liquid crystal display at the tip of a pen that touches and inputs a desired position on the surface of the panel. The reflected light is reflected by peripheral photoelectric conversion elements. By receiving the light, the touch position can be detected.

  Further, in the above description of the embodiment of the present invention, the load detection unit has been described in detail. However, when the load detection unit is configured as a piezoelectric element, the “detecting the pressing load on the contact detection unit” of the present invention is used. Includes “outputting (generating) a voltage based on a pressing load applied to the contact detection unit”. Similarly, the “load reference” of the present invention includes “voltage reference which is a reference based on voltage”. Similarly, the “pressing load detected by the load detecting unit” includes “voltage output (generated) by the piezoelectric element”. As described above, when the piezoelectric element is used as the load detection unit and the piezoelectric element outputs (generates) a voltage based on the pressing load on the contact detection unit, the control unit detects the contact from the voltage output from the piezoelectric element. It may be determined whether or not to perform a predetermined process based on the voltage output from the piezoelectric element without calculating the pressing load on the part. In this case, as described above, if the voltage output from the piezoelectric element satisfies a predetermined voltage reference, the control unit creates a file composed of the dragged object file and the common data of the other object files. If a voltage reference different from the predetermined voltage reference is satisfied, a file including all data of the two files is created.

  In the description of the embodiment of the present invention described above, satisfying a predetermined load criterion means, for example, that the pressing load on the contact detection unit is greater than or equal to a predetermined load threshold, or the pressing load on the contact detection unit is predetermined. The load threshold is exceeded, and the pressing load on the contact detection unit is equal to or greater than the load threshold for a certain time. In the above-described embodiment of the present invention, satisfying the predetermined load standard means that the pressing load is equal to or greater than the predetermined load standard (threshold).

  In the description of the embodiment of the present invention described above, if the pressing load detected by the load detection unit satisfies the second load standard (predetermined load standard), the file of the dragged object, and other Create a file consisting of the common data of the object files, and if a fourth load criterion (different load criterion) higher than the first load criterion is satisfied, create a file that includes all the data of the two files However, the present invention is not limited to this, and if the pressing load detected by the load detection unit satisfies the fourth load criterion, the file includes the common data of the dragged object file and other object files. If a file is created and the first load criterion lower than the fourth load criterion is satisfied, a file including all data of the two files is created. It may be.

  In the description of the embodiment of the present invention described above, the first to fourth load standards are set. However, the first load standard and the fourth load standard are set, and the second load standard and The third load standard may not be set.

  In the description of the embodiment of the present invention described above, the contents of the file have been described using the characters A, A + B, A + C, and A + B + C. However, the contents of B and C are those from which the contents of the file are A. It may indicate a difference. For example, the content of the file is a sentence, A is “November 26 (Wednesday)”, A + B is “November 26”, and A + C is “November 26, 2011 (Wednesday)”. Then, A + B + C becomes “November 26, 2011”. Here, B is that “(Wed)” is deleted, and C is that “2011” is added.
