(First embodiment)
(Description of configuration)
FIG. 1 is an external view showing an example of the apparatus according to the first embodiment of the present invention.
The device 200 is an automatic check-in machine used at airports and the like. The device 200 has a display operation section 100, a non-contact IC card reader 5, a receipt printer 6, a magnetic card reader 7, and a housing 1 to which these are attached. Here, the display/operation unit 100 includes a display unit 21 (FIG. 4) that displays an operation screen (for example, an “operation explanation” screen 3a) and a detection unit 31 (FIG. 4) that detects finger contact or separation from the operation screen. 4), and a lever 8 arranged near the frame 99 . The lever 8 is operated to change the distance between the display section 21 and the detection section 31 .

As a result, the display operation unit 100 has a contact operation mode in which an input operation is performed by touching an operation screen (for example, the “operation explanation” screen 3a) and a non-contact operation mode in which an input operation is performed by moving the finger away from the operation screen. It is possible to switch between the operation mode (separate operation mode). In particular, it is possible to continuously change the operation feeling in the non-contact operation mode.

FIG. 2 is an example of an explanation screen for explaining operations displayed on the display/operation unit 100 (FIG. 1), and FIG. 4 is a perspective view for explaining an operation using the unit 100; FIG. The control unit 50a causes the display unit 21 to display the "operation explanation" screen 3a.

The control unit 50a shown in FIG. 3 includes a CPU (Central Processing Unit) (not shown), a storage unit (not shown), and the like. The display unit 21 displays images using video signals such as RGB signals, DP signals (Display Port signals), HDMI (High-Definition Multimedia Interface) signals output by the control unit 50a.

The “operation explanation” screen 3 a ( FIG. 2 ) is an example of a screen for explaining the operation of the lever 8 . The "operation explanation" screen 3a includes, for example, a character string "operation explanation" and a character string "You can switch between non-contact operation and contact operation on the screen. Please operate the lever to adjust the sensor height." , and an explanatory image. The display unit 21 of the display operation unit 100 is fixed, and the detection surface of the detection unit 31 ( FIG. 4 ) that detects a finger can be moved away from or brought closer to the display unit 21 . By operating the lever 8, if the position of the detection unit 31 is raised, non-contact operation is performed, and if the position of the detection unit 31 is lowered, contact operation is performed.

4 is a cross-sectional view of the display operation unit 100 according to the first embodiment of the invention, and FIG. 5 is a plan view of the display operation unit 100 according to the first embodiment of the invention. 4 is a cross-sectional view corresponding to line IV-IV in FIG.
The display operation unit 100 includes a frame 99, a display unit 21, a detection unit 31, and a mechanism unit 60 (FIG. 6). The detection unit 31 is arranged at the edge of the display surface of the display unit 21, and a detection surface 35 is set. The frame body 99 has an inverted L shape when viewed in cross section, and fixes the display section 21 at its lower portion. The frame 99 has edges 22 and 23 perpendicular to each other and edges 24 and 25 facing the edges 22 and 23, respectively.

The display unit 21 has a rectangular display surface 21a arranged along the XY plane. The detection unit 31 includes groups of infrared light receiving elements 33A (FIG. 7) and 33B arranged along the edges 22 and 23 and groups 32C of infrared light emitting elements arranged along the edges 24 and 25 (FIG. 7). ), 32D. The infrared light emitting element groups 32C, 32D and the infrared light receiving element groups 33A, 33B are arranged at a height H from the display surface 21a, and the arrangement surface constitutes a detection surface 35 for detecting a finger.

The infrared light receiving element group 33A arranged along the edge 22 is composed of a plurality of infrared light receiving elements 33a. The infrared light receiving element group 33B arranged along the edge 23 is composed of a plurality of infrared light receiving elements 33b. 32 C of infrared light emitting element groups arrange|positioned along the edge part 24 are comprised from several infrared light emitting element 32c. The infrared light emitting element group 32D arranged along the edge 25 is composed of a plurality of infrared light emitting elements 32d.

Here, the plurality of infrared light emitting elements 32c and 32d are sequentially scanned so as to emit light, and the irradiation light emitted by each of the infrared light emitting elements 32c and 32d has a spread angle. Therefore, the plurality of infrared light receiving elements 33a and 33b receive light with the intensity distribution of the infrared light emitted by one of the infrared light emitting elements 32c and 32d in sequence.

In this state, when the operator's finger is inserted in the direction of the display surface 21a of the display unit 21, the intensity distribution of light received by the plurality of infrared light receiving elements 33a and 33b changes, so the insertion position can be detected. . Note that the arrangement of the light-emitting elements and the light-receiving elements shown in FIG. 5 is merely an example, and the arrangement may be different from that shown in FIG.

FIG. 6 is a perspective view of the mechanism portion according to the first embodiment of the invention, and FIG. 7 is a cross-sectional view thereof.
The mechanism part 60 connects the fixed frame 57, racks 54a, 54b, 54c, 54d as four tooth plates, pinion gears 53a, 53b, 53c, 53d as four gears, and two pinion gears 53a, 53b. A shaft 58a, a shaft 58b connecting two pinion gears 53c and 53d, a belt 56, two gears 52 and 55, a shaft 58c connecting the two gears 52 and 55, and a lever 8. consists of

The fixed frame 57 is a rectangular frame that fixes the detector 31 (FIGS. 4 and 5). At the four corners of the fixed frame 57, ends of four racks 54a, 54b, 54c and 54d are fixed. The four racks 54a, 54b, 54c, 54d mesh with each of the four pinion gears 53a, 53b, 53c, 53d. As a result, the fixed frame 57 and the detector 31 move vertically (in the Z direction) as the four pinion gears 53a, 53b, 53c, and 53d rotate.

The pinion gear 53 a meshes with the gear 52 and the gear 52 is rotated by the lever 8 . Therefore, the pinion gear 53a and the pinion gear 53b, which are connected via the shaft 58a, are rotated by the lever 8. As shown in FIG. A belt 56 is stretched between a gear 55 connected to the gear 52 and a pinion gear 53c. Therefore, the pinion gear 53 c and the pinion gear 53 d that are connected via the shaft 58 b are rotated by the lever 8 . Further, the gear ratio between the gear 52 and the pinion gear 53a is equal to the ratio between the diameter of the gear 55 and the diameter of the pinion gear 53c.

FIG. 7 is a cross-sectional view of the mechanism when switching from the non-contact operation mode to the contact operation mode. In FIG. 7, arrow A indicates the operating direction of the lever 8, and arrow B indicates the rotating direction of the gears 52 and 55 on the same rotating shaft (shaft 58c) as the lever 8. As shown in FIG. An arrow C indicates the rotation direction of the pinion gear 53a meshing with the gear 52. As shown in FIG. An arrow D indicates the operating direction of the rack 54a meshing with the pinion gear 53a. That is, when the lever 8 is turned so that the gears 52 and 55 rotate in the direction of the arrow B, the racks 54a and 54b move in the direction of the arrow D. As shown in FIG.

An arrow E indicates the rotating direction of the belt 56 following the rotation of the gear 55 . An arrow F indicates the rotation direction of the pinion gear 53c driven by the rotation of the belt 56. As shown in FIG. An arrow G indicates the operating direction of the rack 54c meshing with the pinion gear 53c. That is, when the lever 8 is rotated so that the gears 52 and 55 rotate in the direction of the arrow B, the racks 54c and 54d move in the direction of the arrow G. As shown in FIG. Therefore, when the lever 8 is turned so that the gears 52 and 55 rotate in the direction of arrow B, the four racks 54a, 54b, 54c and 54d move the same distance and in the same direction.

Thus, by operating the lever 8, the separation distance (height H (FIG. 4)) between the display surface 21a (FIGS. 4 and 5) of the display unit 21 and the detection surface 35 can be adjusted. Then, subsequent screen operations can be performed with the adjusted separation distance.

(Explanation of effect)
As described above, the display operation unit 100 of the present embodiment has the separation distance (height H (Fig. 4)) can be adjusted by operating the lever 8. This allows the operator to switch between the "contact operation" and the "non-contact operation". In addition, it is possible to continuously change the operational feeling (for example, the magnitude of erroneous operations due to parallax) when performing non-contact operations.

Further, according to the display operation unit 100 of the present embodiment, unlike the touch panel input device described in Patent Document 1, it is possible to avoid contact with the display surface 21a without arranging a plurality of detection units 31 . . In addition, since the operator can adjust the spacing by himself/herself prior to a series of business processes, it is possible to operate hygienically "non-contact" or "contact" to avoid erroneous operations due to parallax. operation becomes possible.

(Second embodiment)
In the first embodiment, the separation distance (height H (FIG. 4)) between the display surface 21a and the detection surface 35 is continuously changed by the lever 8, but the separation distance is changed by using the motor 59 (FIG. 11). It can also be changed continuously.

FIG. 8 is an external view of a device that is a second embodiment of the present invention.
As with the device 200 of the first embodiment, the device 201 has a display operation unit 101, a non-contact IC card reader 5, a receipt printer 6, a magnetic card reader 7, and a housing 1 to which these are attached. is doing. However, the display/operation unit 101 differs from the display/operation unit 100 of the first embodiment in that it does not have the lever 8 .

FIG. 9 is a diagram showing an example of a display screen displayed on the display unit of the device according to the second embodiment of the present invention, and FIG. 10 shows the display operation unit of the device according to the second embodiment of the present invention. It is a perspective view which shows the selection operation which used. Note that FIG. 10 shows a control unit 50b and a motor 59 that operate the display operation unit 101. As shown in FIG.

The "screen operation selection" screen 3b is an example of a display screen displayed on the display unit 21 at the beginning of the transaction under the control of the control unit 50b. The control unit 50b (FIG. 10) is configured to control the motor 59 based on a selection operation using the "screen operation selection" screen 3b. The motor 59 is provided in place of the lever 8 (FIGS. 1, 3, 6, 7) of the first embodiment, and the distance between the display surface 21a and the detection surface 35 (height H (FIG. 4) ) is changed continuously.

The “screen operation selection” screen 3 b ( FIG. 9 ) includes, for example, a character string “screen operation selection”, a “contact” button 11 , a non-contact button 12 and an arrow button 13 . The "contact" button 11 is composed of a "high" button 12a, a "middle" button 12b, and a "low" button 12c. The arrow buttons 13 include an "↑" button 13a and a "↓" button 13b.

When the "contact" button 11 is touched, the control unit 50b controls the contact between the display surface 21a of the display unit 21 and the detection surface 35 of the detection unit 31 (infrared light emitting element groups 32C and 32D, infrared light receiving element groups 33A and 33B). The spacing (height H (FIG. 4)) is set to the minimum value H1 (eg, 5 mm). This enables a contact operation (including a proximity operation) on the display surface 21a.

On the other hand, when the "high" button 12a is touched, the controller 50b sets the separation distance (height H (FIG. 4)) to the maximum value H4 (eg, 50 mm). In addition, the "medium" button 12b and the "low" button 12c set the spacing (height H (FIG. 4)) to intermediate values H2 and H3 (H1<H2<H3<) between the minimum value H1 and the maximum value H4. H4). Here, it is assumed that the value (intermediate value H3) corresponding to the "middle" button 12b is the optimum height for a normal operator.

The "↑" button 13a raises the detection surface 35 by one step and lengthens the interval (height H (Fig. 4)) by one step. On the other hand, the "↓" button 13b lowers the detection surface 35 by one step and shortens the spacing (height H (Fig. 4)) by one step.

FIG. 11 is a perspective see-through view of a mechanism section according to a second embodiment of the present invention.
A mechanism section 61 of the display operation section 101 differs from the mechanism section 60 (FIG. 6) of the first embodiment in that a motor 59 is provided instead of the lever 8. As shown in FIG. The motor 59 is, for example, a stepping motor, and rotates step by step under the control of the controller 50b (FIG. 10). The controller 50b may control the position of the detection surface 35 with the motor 59 by adding a position detection device (not shown) for detecting the position of the detection surface 35. FIG.

FIG. 12 is a flow chart for explaining the operation of the display operation section of the device according to the second embodiment of the present invention. This flow is executed at the start of trading.
First, the control unit 50b controls the motor 59 (FIG. 11) to return the separation distance (height H (FIG. 4)) to the non-contact "middle" value H3 (S1). After the process of S1, the control unit 50b determines the states of the non-contact buttons 12 (the "high" button 12a, the "middle" button 12b, the "low" button 12c) and the "contact" button 11 (S2). If neither the non-contact button 12 nor the "contact" button 11 is touched ("non-detected" in S2), the control unit 50b determines the state of the arrow button 13 (S3).

Further, when the "contact" button 11 is touched ("contact" button in S2), the control unit 50b controls the display surface 21a of the display unit 21 and the detection unit 31 (infrared light emitting element groups 32C and 32D, infrared light receiving element group 33A). , 33B) from the detection surface 35 (height H (FIG. 4)) is set to the minimum value H1, and the state of the arrow button 13 is determined (S3). On the other hand, when the non-contact button 12 is touched ("non-contact" button in S2), the control unit 50b sets the spacing (height H (FIG. 4)) to values H2, H3, and H4 (S5), The state of the arrow button 13 is determined (S3). Specifically, the control unit 50b sets the separation distance (height H (FIG. 4)) to a value H4 when the "high" button 12a is touched, and sets the separation distance (height H (FIG. 4)) to a value H4 when the "middle" button 12b is touched. H (FIG. 4)) is set to the value H3, and when the "low" button 12c is touched, the separation distance (height H (FIG. 4)) is set to the value H2. Here, H4>H3>H2>H1.

In S3, if neither the "↑" button 13a nor the "↓" button 13b is touched (not detected in S3), the control unit 50b determines whether or not the transaction is continued (S6).

On the other hand, if the "↑" button 13a is touched ("upward arrow" in S2), the control unit 50b controls the motor 59 to extend the spacing (height H (FIG. 4)) by one step. (S7) and decides whether to continue the transaction (S6). Further, if the "↓" button 13b is touched ("downward arrow" in S2), the control unit 50b controls the motor 59 to shorten the spacing (height H) by one step (S8). , to determine whether to continue the transaction (S6).

If the transaction continues ("Continue" in S6), the control unit 50b returns the process to S2 and repeats the determination of the non-contact button 12 and the "contact" button 11. On the other hand, if the transaction has ended (“End” in S6), the control unit 50b returns the separation interval (height H) to H3 (non-contact “Medium”), and ends the process. This allows the next user to initiate a contactless "medium" transaction and operate contactless regardless of the usage status of the previous user.

As described above, according to the display operation unit 101 of the present embodiment, the display surface 21a of the display unit 21 and the detection surface of the detection unit 31 (infrared light emitting element groups 32C and 32D, infrared light receiving element groups 33A and 33B) (height H (FIG. 4)) can be continuously varied by a motor 59 (FIG. 11). Further, by touching the "contact" button 11 and the non-contact button 12 ("high" button 12a, "middle" button 12b, "low" button 12c) displayed on the display unit 21, the separation distance (height H) is changed. They are fixed to preset values H1, H2, H3 and H4.

By touching the arrow buttons 13 (“↑” button 13a, “↓” button 13b), the spacing (height H (FIG. 4)) can be finely adjusted step by step.

(Modification)
The present invention is not limited to the above-described embodiments, and for example, the following modifications are possible.
(1) In the display operation units 100 and 101 of the above-described embodiments, the display unit 21 is fixed and the detection unit 31 is movable. When the detection unit 31 is fixed, the distance between the upper surface of the frame 99 (FIGS. 1 and 4) and the detection surface 35 (FIG. 4) of the detection unit 31 is fixed. Moreover, since the distance between the upper surface of the frame body 99 and the display surface 21a of the display unit 21 is fixed at the minimum value during the touch operation, the operation feeling is good.

(2) In the device 201 of the second embodiment, the separation distance (height H (FIG. 4)) was returned to the non-contact "medium" both at the start of the transaction and at the end of the transaction (S1). The non-contact "medium" may be restored at either the start or the end of the transaction. Also, the separation distance (height H (FIG. 4)) may be returned to the non-contact "medium" when the customer detection sensor is turned off instead of when the transaction is started. According to this, when the same customer operates continuously, the separation distance does not return to non-contact "middle".

(3) In the second embodiment, the customer was able to switch between contact operation and non-contact operation. In such a case, the system management terminal transmits a "telegram regarding operation switching" to a plurality of devices 201 in a specific area via the network, and the device 201 that receives the telegram becomes incapable of contact operation (non-contact operation). limited to operations). In other words, a screen in which the "contact" button 11 is deleted from the "screen operation selection" screen 3b of FIGS. 9 and 10 is displayed, and the user is made to select between non-contact "low" and "high". This screen may additionally display the message "To prevent the spread of infectious diseases, contactless operation is restricted." By doing so, it is possible to suppress infection due to the contact operation.

(4) The devices 200 and 201 in each of the above-described embodiments are automatic check-in machines, but any device may be used as long as it has a touch panel display device. Specifically, for example, an automatic teller machine such as an ATM (Automated Teller Machine) or an image forming apparatus may be used. Furthermore, it may be a smaller or larger device.
