Description

  The present invention relates to a display input device that performs an input operation by a user touching a display surface.

  2. Description of the Related Art In an electronic device such as an information processing terminal, an input menu (options) including characters and patterns is displayed on a display device on a screen, and a touch panel is arranged on the screen. When any part of the input menu displayed on the display screen is touched, information about the position coordinates of the touched part is output. Since this display screen is touched by an unspecified number of users, it is easily soiled by sweat and the like, and is chronically easily soiled by dust, tar, insects, etc., giving the user discomfort and being unsanitary. . In order to solve such a problem, a device that detects dirt on a display screen and activates a cleaning unit has been considered (for example, see Patent Document 1). To solve the problem, a cleaning mechanism has been proposed in which a protective screen that covers the display screen is provided, the protective screen is wound up, and dirt is wiped off with a brush that contacts the protective screen. Furthermore, the brush is impregnated with a cleaning liquid so that dirt can be more reliably removed (for example, see Patent Document 2).

When cleaning the display screen regularly, if the cleaning is performed while the normal reception menu etc. is displayed, it is not possible to distinguish the dirty part and the non-dirty part due to the color of the screen, and the dirt is left behind Sometimes. To solve such a problem, there is one in which a dark color image is displayed on a display screen when a cleaning mode is designated so that dirt adhering to a touch panel surface can be clearly seen (for example, Patent Document 3). reference)

  Although there is a technology to clean the touch panel surface touched by the user, the cleaning timing is "time that does not limit the use of the user", that is, since the cleaning operation is not performed under the supervision of the user, However, it is difficult for the user to determine whether the cleaning operation has been performed. Only careful observation of the display screen indicates that it is not dirty. Therefore, even if the display screen is not unsanitary, the user's discomfort cannot be reliably removed in reality.

  The present invention has been made in view of the above problems, and requires a cleaning operation when an operation key on a display screen is touched a specified number of times or more. At the end of cleaning, a display indicating that cleaning has been completed is performed. Therefore, it is an object of the present invention to provide a device that allows a user to visually recognize that a cleaning operation has been performed and to remove discomfort.

  In order to solve the above problems, the present invention provides a display input device having a display surface and a transmissive touch panel input surface, wherein a counting means for counting the number of finger touches on the transmissive touch panel input surface, and the number of finger touches is set in advance. In the cleaning mode, when a finger touch is detected on the input surface of the transparent touch panel, the finger touch coordinates are specified, and the display on the display surface corresponding to the finger touch coordinates is erased. Or control means for changing the color or line to a visually identifiable color.

  Since the display surface touched by an unspecified number of users can be practically cleaned and disinfected, and the fact that the cleaning and disinfection has been performed can be easily grasped, no discomfort is given to the user.

  An embodiment of the present invention will be described. FIG. 1 is a control block diagram of a display input device in the automatic issuing machine of the present invention, and FIG. 2 is a front view of the automatic issuing machine.

  In the figure, reference numeral 1 denotes a display input device, which is a part for performing an input operation for operating the automatic issuing machine 2. The automatic issuing machine 2 is connected to a host computer 3 (not shown) via a line, and can receive personal information stored and managed in the host computer 3. Although personal information that is connected and communicated through a line has a predetermined security measure, the description is omitted because it is not directly related to the present invention.

  The display input device 1 is used to display an operation screen and input information for a user to obtain a desired certificate. An operation screen at the start of the operation, for example, a certificate such as "copy of resident's card" or "seal certificate" is displayed on the display input device 1, and the processing is selected and proceeded according to the display. The display input device 1 is configured with a transparent touch panel input surface (hereinafter referred to as a touch panel) for a user to operate in the automatic issuing machine 2.

  Reference numeral 21 denotes a card insertion / return port into which a Basic Resident Register card (hereinafter, referred to as a Juki card) 211 and a maintenance card 212 are inserted and returned, and internally reads stored information from the Juki card 211 or the like. The card reader 213 is connected. Reference numeral 22 denotes a bill insertion slot, which is a part into which a user inserts bills when issuing fees for various certificates are paid by bills. The bill processing unit 221 connected to the bill insertion slot 22 identifies the authenticity and denomination of the inserted bill, further counts and stores the number. Reference numeral 23 denotes a coin insertion slot, which is a part into which a user inserts a coin when the issue fee is paid by coin. The coin processing unit 231 connected to the coin insertion slot 23 identifies the authenticity and denomination of the inserted coin, and further counts and stores the number of coins.

  Numeral 24 is a change dispensing port, which is a portion for discharging money corresponding to the change amount when a change occurs when the issuance fee is paid. The change dispensing port 24 is connected to the banknote processing unit 221 and the coin processing unit 231 described above, and the change is dispensed from the portion. In addition, it also has a function of a return port for returning coins (foreign matter) that have been inserted as coins but cannot be determined for authenticity or denomination. Reference numeral 25 denotes a receipt receiving port, which is connected to a receipt processing unit 251 that prints and discharges a statement slip and a receipt (hereinafter referred to as a receipt) 252 of the issue fee.

  Reference numeral 26 denotes a document receiving box, which is connected to a certificate printing unit 261 for printing, signing, and binding a certificate 262 to be issued, and is an output box for the certificate 262 desired by the user. The document receiving box 26 has monitoring means for monitoring the presence / absence of the certificate 262 discharged into the box. When the user removes the certificate 262, it can be detected. . Reference numeral 27 denotes a clerk call button, which is a part for a user to call a device manager or the like when the operation is unknown. Reference numeral 28 denotes a control unit for controlling each of the above units.

  Next, details of the display input device 1 will be described. Reference numeral 11 denotes a color LCD display unit (hereinafter, referred to as a display unit) which is a display surface, and is a notifying means for displaying information necessary for the user in characters and pictures. The image display of the display unit 11 is controlled by the LCD controller 12. The display unit 11 displays operation procedures and other information in the form of illustration characters, words, and pictures, and displays operation keys such as "copy of resident's card" and "certificate of seal". A touch panel 13 is provided as a transparent touch panel input surface which is divided into a plurality of pixels and covers each pixel so as to cover the display unit 11.

  The touch detection surface of the touch panel 13 is such that a matrix optical line is formed by providing a plurality of infrared light emitting elements and light receiving elements around a transparent flat plate at intervals of, for example, 2.54 mm. When the finger interrupts the infrared ray path that is orthogonally radiated at a predetermined timing, the coordinates touched by the finger are detected. The touch panel controller 14 is positioned as a coordinate search unit for searching for the coordinates. Since the touching portion of the touch panel 13 is constituted by the optical path including the issuing element and the light receiving element as described above, it is actually a transparent flat plate covering the upper surface of the display section 11. In the present application, the touch panel 13 includes the transparent flat plate. Needless to say, a resistive film system (transparent electrode system), an ultrasonic system, and a capacitance system other than the optical scanning system may be used.

  Reference numeral 15 denotes a CPU (Central Processing Unit) serving as a control means, which controls the above-described display control of the display unit 11 and the reading of information from the memory 16. The LCD controller 12 and the touch panel controller 14 are also controlled by the CPU 15. Reference numeral 15a denotes a cleaning mode switching unit that activates the cleaning mode when the number of finger touches reaches a specified number from information from a counting unit 15b that is a counting unit that counts the number of finger touches to a specific operation key. is there. A memory 16 stores display image data and character data for guidance.

Next, a method of detecting finger eclipse coordinates will be described with reference to FIG.
FIG. 3 is an explanatory diagram showing finger touch detection, in which the touch panel 13 is conceptually described. In the figure, light emitting elements emitting infrared rays 13X and 13Y are arranged in an array at an interval of 2.54 mm in the left column (Y1 to Yn) and the upper row (X1 to Xn). In the right column and the lower row, light receiving elements arranged opposite to the light emitting elements are arranged in an array at intervals of 2.54 mm. Then, the touch panel controller 14 emits light from the light emitting elements Y1 to Yn sequentially at a predetermined timing, and at that time, the presence or absence of a touch is detected based on the presence or absence of output of the light receiving element. The coordinates of the finger touch point can be detected by repeatedly performing the presence or absence of the output of the light receiving element in a short time.
Similarly, for the rows, the touch panel controller 14 sequentially emits light from the light emitting elements X1 to Xn at predetermined time intervals, and at that time, detects the presence or absence of a finger touch by the output of the light receiving element. In this manner, the touch coordinates are detected by detecting the output states of the light receiving elements in the columns and rows.

In FIG. 3, when the light receiving element does not detect the infrared ray, the output “1” is described at the right end and the lower end. When the output becomes “1”, the pixel is set to one unit. The finger touch coordinates of this pixel are associated with the display pixels of the display unit 11 in advance. That is, pixels are assigned to the display unit (LCD) 11 at intervals of 2.54 mm. In this way, the finger touch coordinates (position) obtained from the detection result of the light receiving element is actually detected as the finger touch area 13W (thick frame line) including the incomplete touch area as shown in FIG. However, they are ignored and handled as finger touch coordinates.
13P indicates a position where a fingertip of a staff member or the like actually touches the touch panel 13, and a hatched portion is a pixel whose finger touch is detected. When two fingers are touched, two areas 13W (shown by thick frames) are detected. When an area 30a (shown by a dashed line) or the like covered by the nonwoven fabric 30, which will be described later, is detected as finger touch coordinates, the center coordinates may be calculated and used.

Next, the processing operation of the automatic issuing machine of the present invention will be briefly described. FIG. 4 is a flowchart showing the processing operation. Note that SA indicates an operation step, and the description will be made assuming that the user requests to issue only one copy of “Resident's card”.
In the standby state, the automatic issuing machine 2 displays a standby screen for displaying information, a guidance message, and the like on the display unit 11 (SA1). When the user approaches the automatic issuing machine 2, an approach detector (not shown) detects this (SA2) and switches the display unit 11 from the standby screen to the input menu selection screen (SA3). This input menu selection screen is as shown in FIG. 5, and a resident card copy button 101, a seal certification button 102, a tax payment certification button 103, a confirmation button 104 and a cancel button 105 are displayed at predetermined positions. I have. It should be noted that the screen-cleaned mark 110 displaying the “cleaning and sanitizing” character in FIG. 5 may or may not be displayed (details will be described later).

  When the user touches the resident card copy button 101 and subsequently touches the confirmation button 104, the menu is selected (SA4). The CPU 15 causes the display unit 11 to display “Please insert a basic resident register card”. When the resident registry card 211 is inserted, the control unit 28 reads information stored in the inserted resident registry card 211 (SA5). The CPU 15 receives the signal indicating that the reading of the personal information stored in the resident registry card 211 has been completed, performs a ten-key display 109 (not shown), and requests input of a password. When the password is input (SA6), the CPU 15 sends the password information to the control unit 28. The control unit 28 transmits the information read from the resident registry card 211 and the received password information to the host computer 3.

  When a signal indicating that the user is a legitimate user is sent from the host computer 3, the control unit 28 displays a fee on the display unit 11 via the CPU 15 and requests for insertion of money. A user inserts bills and coins through the bill insertion slot 22 and / or the coin insertion slot 23. The inserted bills and coins are subjected to authenticity, denomination determination and counting in the bill processing unit 221 and the coin processing unit 231 respectively. The controller 28 compares the count result (money amount) with the commission amount and, when change occurs, discharges the change from the change dispensing port 24 (SA7).

  The control unit 28 starts printing the certificate 262 (copy of the resident's card) and starts printing the receipt 252 when confirming that the same amount or more as the fee has been inserted. On the receipt 252, the date and time, the name of the document, the fee, the change amount, if any, the wording indicating receipt, etc. are printed. When the printing of the receipt 252 is completed, it is discharged to the receipt receiving port 25 (SA8). Subsequently, the resident registry card 211 is also discharged to the card insertion / return port 21 and returned to the user (SA9). Then, one of the certificates 262 is discharged to the document receiving box 26, and the issuing process is completed (SA10). When the cancel button 105 is touched, the screen returns to the operation screen one step before.

Next, the cleaning process guidance for the finger touching section will be described with reference to the flowchart shown in FIG.
The CPU 15 operates the counting unit 15b for counting the number of times the confirmation button 104 is touched on the input menu selection screen shown in FIG. 5 (SB1). The reason why the number of times of touching of the confirmation button 104 is set is that, regardless of which certificate is selected, the operation of touching the confirmation button 104 is always performed, so that the approximate number of processes can be grasped. Therefore, it goes without saying that the control unit 28 may add up the number of issued certificates and the like. When the count value reaches the specified number of times (for example, 50 times), the CPU 15 shifts to the execution of the cleaning work (SB2).

  First, the issuance of the certificate 262 requested by the user, for example, the "resident's card copy" is monitored, the resident registry card 211 and the receipt 252 are removed, and the "residence card copy" is displayed in the document receiving box 26. Is detected (SB3), the display section 11 displays, "It is time to clean / disinfect the screen by the attendant, please wait for a while" (SB4). On the other hand, the CPU 15 transmits a cleaning request signal to the control unit 28, and causes the host computer 3 to transmit a signal indicating a cleaning request to the management terminal 5 (for example, a personal computer for a cleaning staff) connected to the line (for example, a cleaning staff member). SB5).

  When the clerk approaches the automatic granting machine 1 (SB6), a guidance screen such as "I am preparing for cleaning now, if you are in a hurry, please come to the counter" is displayed to inform that preparation is being made for cleaning. (SB7). Since the automatic issuing machine 1 cannot discriminate between the attendant and the user in terms of operation, the screen is switched when the approach is detected. The attendant inserts the maintenance card 212 from the card insertion / return port 21 (SB8). Even though the maintenance card 212 has the same outer shape as the resident registry card 211, the stored information is different, and is merely information for simply switching to the cleaning mode. The stored information of the maintenance card 212 is read out by the card reader unit 213 (SB9), analyzed by the control unit 28, and transmitted to the CPU 15.

  In response to this signal, the CPU 15 operates the cleaning mode switching unit 15a to switch the screen control to the cleaning mode. A staff guidance screen as shown in FIG. 7 is displayed (SB10). The attendant prepares a chemical rag or nonwoven fabric (hereinafter, referred to as a nonwoven fabric) 30 and a cleaning liquid 31 formed of natural fibers, chemical fibers, or recycled fibers, and proceeds to the place of the automatic dispensing machine 1. When the clerk touches the start button 106 (SB11), the CPU 15 reads the operation key screen information displayed in the cleaning mode from the memory 16 and displays all the operation keys on the display unit 11 (SB12). It is to be noted that the present invention is not limited to displaying all the operation keys, but may display only some of the operation keys except for the operation keys with a low finger touch frequency.

When the stop button 107 is touched in step SB11, the process returns to the input menu selection screen, performs the certificate issuing process only once, and returns to step SB3. As a result, when the user is making a queue, the processing can be continued under the attendance of the attendant, and the service does not deteriorate.
The above display is different from normal operation keys, and at the display position of the numeric keypad display 109, the numeric keypad position is the same, but at least the outer frame of the key is displayed as a non-character key 109a having no display character. This display example is shown in FIG. The reason why the non-character key is used is that if the operation character is displayed, it is misunderstood by the user that the operation is being performed. In this case, the display color may be replaced with the display color of the normal operation key.

  The nonwoven fabric 30 monitors the touch on the touch panel 13 (actually, a site where a finger pressure is applied) (SB13), and transmits the finger touch coordinates detected by the touch panel controller 14 to the CPU 15. The CPU 15 immediately switches to another color only at the display location of the display unit 11 corresponding to the received touch coordinate information (SB14). For example, if the background color is “blue” as the first color and the non-character key 109a or the like is “gray”, which is the second color, the part where the finger touch is detected is the background color that is the first color. (Blue). When the cleaning operation (screen wiping) is performed in the direction of arrow A shown in FIG. 8B, the portion where the finger touch is detected is changed to the same as the background color (the difference in color that cannot be visually recognized is the same). . Then, in the example shown in the figure, a display is made in which a part of the outer frame line of the characterless keys 101a, 102a, 107a is deleted (cannot be distinguished from the background color). Note that the second color may be changed to the third color “cream”, the outer frame line may be changed from a solid line to a dashed line, and furthermore, a change from a thick line to a thin line.

  The attendant visually determines that the portion where the outer frame line segment such as the non-character key 109a is displayed is an incompletely cleaned area. When the entire display area of the characterless key 109a or the like is touched (cleaned), the display unit 11 is controlled so that not only the characterless key 109a but also the outer frame line is not displayed. This phenomenon is as if the characters and figures written in chalk on the blackboard were erased with the blackboard eraser. When the display areas of all the operation keys are touched (wiped) in this way (SB15), the CPU 15 displays a cleaning end screen as shown in FIG. 8C. When the clerk touches the end button 108, "Remove card" is displayed on the display unit 11 (SB16), and a card ejection request is issued to the control unit 28. The controller 28 drives the card reader 213 to eject the maintenance card 212.

  When the maintenance card 212 is removed by the attendant (SB17), the CPU 15 switches to a screen display indicating the end of cleaning and disinfection as shown in FIG. 8D and enters the standby mode (SB18). The attendant and the user can visually recognize that cleaning and disinfection have been performed by looking at this screen. The CPU 15 clears the finger touch count value of the confirmation button 104 by the counting unit 15a. When the user who has been waiting for the certificate issuance operation touches the start button 106, the CPU 15 shifts the display to the input menu selection screen shown in FIG. Information indicating that cleaning has been completed, for example, the display of the screen-cleaned mark 110 is added to this display screen, and thereafter, the counting unit 15b starts counting the number of finger touches of the confirmation button 104, and the second predetermined number of times (for example, 20) Times). When the second specified number of times is exceeded, the display of the screen-cleaned mark 110 is controlled to be erased by the CPU 15.

  In the second embodiment, control is performed to randomly change the display (touch) position of the operation key. Such control is particularly performed when the display position is changed so that the input of the password or the like is not read even if the third party sees the input from the finger touch position. In the case of the second embodiment, the background color of the display unit 11 is displayed in the first color (for example, blue) without displaying the characterless key in step SB12 described above. Then, only the place where the touch panel 13 is touched is changed to a second color (for example, gray) or a third color (for example, cream) that can be visually identified as being different from the first color.

  Referring to FIG. 9, first, at the start of the cleaning operation, the entire area (background) of the display unit 11 is displayed in a single display color (first color). Then, the touch panel controller 14 detects the coordinates at which the finger of the attendant first touches the touch panel 13 as the starting point 13a. When detecting the position of the starting point 13a, the CPU 15 continuously determines the coordinates detected continuously in accordance with the movement of the finger or the like as a trajectory as shown by a chain line in FIG. 9A. The display color of the coordinate position of the display unit 11 corresponding to the coordinates of the touched locus is changed. The display color changing section 13b is displayed as shown in FIG. In this manner, the entire area of the display unit 11 is wiped off with the nonwoven fabric 30, but the unwiped part remains as the untouched part 13c and is displayed in the same color as the background color (white blank part shown in the figure), so that it can be easily identified.

  In this manner, when the wiping of the entire area is completed, there is no longer any part having the background color as the untouched part 13c. When the CPU 15 detects that the untouched portion 13c has disappeared, the CPU 15 performs the above-described display of FIG. 8C and ends the cleaning. Information indicating that cleaning has been completed (for example, a screen-cleaned mark 110) is added to the subsequent input menu selection screen. In the above description, the process is not completed unless the non-touched portion 13c has been detected. However, the present invention is not limited to this, and the allowable amount (for example, the touched portion is 90% or more). That is, even if the untouched portion 13c remains, it can be controlled to end. Further, a technique for continuously recognizing a finger touching portion can be easily realized as disclosed in JP-A-9-245224.

  In the above-described embodiment, the color finally displayed is changed by one finger touch detection in accordance with the coordinates touched by the finger on the touch panel. However, the present invention is not limited to this. For example, in the first touch detection, the density is slightly changed, in the second touch, the color is further changed, and in the third touch detection, the display color is changed stepwise so as to become the final display color. You may let it. In this case, the present invention can be applied to a case where a plurality of wiping operations are required, such as when the dirt is severe or when there is a restriction on the use of the cleaning liquid (for example, when dry wiping is recommended). Furthermore, during normal service, if the operation key color and the background color are automatically changed in accordance with the number of times the confirmation key is touched, the time at which the cleaning request occurs when the attendant has the opportunity to visually check the screen color You can make predictions.

  FIG. 10 is a control block diagram of the display input device according to the third embodiment. The image input unit 17 and the image reading controller 18 are different from the display input device according to the first embodiment (FIG. 1). Other features are the same as those described in the first embodiment, and a description thereof will not be repeated. The configuration of the image input means 17 may be the one disclosed in Japanese Patent Application Laid-Open No. 11-53113. As an operation, when the situation requiring cleaning is reached, the entire area of the display unit 11 is operated by setting the entire area of the display unit 11 to a white display color, and the entire area of the display unit 11 is scanned. The image collected by this scanning is analyzed and compared with a clean white display screen previously collected. Then, a portion having a density difference is cut out based on the comparison result, and it is determined that there is dirt. Only the portion (coordinate information) is displayed on the display unit 11 by changing the display color as a contaminated portion 13e as shown in FIG.

  By displaying the contaminated portion 13e in this way, the attendant can more carefully clean the site. Further, after cleaning, the image input unit 17 can be scanned to analyze the image and confirm the quality of cleaning. By displaying the contaminated portion 13e visually, it is possible to more easily recognize the cleaning location than the conventional technique (particularly, Patent Document 3).

  FIG. 12 is a control block diagram of the display input device according to the fourth embodiment. The protection screen 19 and the screen controller 20 are different from those of the display input device according to the first embodiment (FIG. 1). The other parts are the same as those shown in the first embodiment, and a description thereof will be omitted. In addition, if the touch panel 13R is of a resistive film type, mounting is easy. The structure and control of the protective screen 19 may be those disclosed in Japanese Patent Application Laid-Open Nos. 10-31431 and 2001-321732. The difference is that, with the movement of the protection screen 19, the screen display of the display unit 11 also moves (scrolls) and changes in the same direction as the protection screen 19.

  As shown in FIG. 13, when the protection screen 19 is moved from right to left (rolled up to the left) as shown by the arrow B, the display of the operation keys is also moved to the left while scrolling the display substantially in accordance with the moving speed. To control the display screen. More specifically, FIG. 14A shows a state before the start of cleaning, and operation keys are displayed on the display unit 11. Here, when the protection screen 19 is wound up to the left side, the cleaning-in-progress display 110a appears from the right end as shown in FIG. 14B and moves to the left side. In this manner, the cleaning required portion 19a is wound up to the left. When the protection screen 19 for one screen is wound up, the entire display surface is covered with the uncontaminated portion 19b. When the movement in the direction of arrow B ends, the screen returns to the initial screen. When this screen is visually observed by the user, it is possible to visually grasp that cleaning and disinfection have been performed.

  The present invention is not limited to the automatic issuing machine of the above embodiment. That is, unspecified large numbers of tickets (ticket) vending machines installed in stations and convenience stores, reception terminals at hospitals and event entrances, unlocking devices for entry control of condominiums and the like, and ATMs of financial institutions. It can be used for a display input device operated by a user. Furthermore, if the cleaning liquid contains a substance having a deodorizing effect or a fragrance (for example, a fragrance of fruit), and the screen-cleaned mark is a substance that generates the fragrance (for example, a picture of the fruit), the user can use the cleaning liquid. It is also possible to notify the user of the cleaning by visual inspection.
