This application is based on Japanese Patent Application No. 2014-266994 filed with the Japan Patent Office on Dec. 29, 2014, the entire content of which is hereby incorporated by reference.
1. Field of the invention
The present disclosure relates to an image processing apparatus, and particularly to an image processing apparatus that conducts short-range wireless communication with an information terminal.
2. Description of the Related Art
In recent years, some terminal devices such as smart phones and tablet terminals are equipped with a function that conducts short-range wireless communication, for example, near field communication (NFC). In this case, a user can conduct data communication using such a terminal device by waving the terminal device over a predetermined position of a device with which the terminal device is communicating. Some image processing apparatuses such as multi-functional peripherals (MFPs) have also been proposed which can conduct short-range wireless communication with a terminal device.
An image processing apparatus that conducts short-range wireless communication with a terminal device is disclosed in Japanese Laid-Open Patent Publication No. 2010-114784, for example. This image processing apparatus is provided with a reading panel, which is spaced from an operation panel for displaying operation information, and includes a mounting surface for reading the information over short-range wireless communication.
Japanese Laid-Open Patent Publication No. 2014-120915 discloses a communication system including a terminal and a communication apparatus. In this communication system, a first type of wireless communication (NFC) is used to establish a second type of wireless communication (WiFi®: Wireless Fidelity) connection. Data on the terminal side is then printed by the communication apparatus. In this system, a series of operations in the flow is displayed on display units of both the terminal and the communication apparatus.
Japanese Laid-Open Patent Publication No. 2009-216866 discloses a video display apparatus equipped with a flat display-type display panel. This video display apparatus includes, on a rear surface of the display panel, an antenna for short-range wireless communication which is approximately the same in size as the display panel.
With the image processing apparatus that conducts short-range wireless communication with a terminal device, a user needs to simultaneously check the contents displayed on both the operation panel on the image processing apparatus side and the display device on the terminal device side. In the image processing apparatus, the position of the operation panel (height, angle, etc.) may be changed in accordance with the user's state.
However, in the case where the reading panel is spaced from the operation panel in the image processing apparatus as disclosed in Japanese Laid-Open Patent Publication No. 2010-114784, the user needs to take a troublesome action in order to simultaneously check a display on the operation panel side and a display on the terminal device side. One example of such a troublesome action is for the user to turn his/her eyes to both the displays. Another example thereof is for the user to change the position of at least one of the operation panel and the reading panel. Furthermore, if the position of the reading panel is changed in accordance with the position of the operation panel, and then the position of the operation panel is changed, the user needs to take a troublesome action, that is, to change the position of the reading panel again in accordance with the changed position of the operation panel.
The present disclosure was invented in view of the actual circumstances described above, and an object thereof is to allow a user to simultaneously check both a display of an operation panel of an image processing apparatus and a display of a terminal device, without the need for a troublesome action.
According to one aspect of the present disclosure, an image processing apparatus is provided that is capable of conducting short-range wireless communication with a terminal having a first display unit. The image processing apparatus includes an operation panel including a second display unit, and a sensor configured to sense a radio wave from the terminal for short-range wireless communication. The operation panel is capable of changing a position thereof relative to a main body of the image processing apparatus. The operation panel includes a touch area arranged on the operation panel, wherein the touch area is an area where the terminal is sensed by the sensor.
According to another aspect of the present disclosure, an image processing apparatus is provided that is capable of conducting short-range wireless communication with a terminal. The image processing apparatus includes an operation panel including a display unit and removable from a main body of the image processing apparatus, and a sensor configured to sense a radio wave from the terminal for short-range wireless communication. The operation panel is capable of changing a position thereof relative to a main body of the image processing apparatus. The operation panel includes a touch area arranged on the operation panel, wherein the touch area is an area where the terminal is sensed by the sensor.
The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.
Embodiments of the image processing apparatus will be hereinafter described with reference to the drawings. In the following description, identical parts and components are labeled with identical signs. These parts and components are also identical in name and function. Thus, the description thereof will not be repeated.

In MFP 100, operation panel 300 contains an antenna for short-range wireless communication (short-range communication unit 380 (
When the position of operation panel 300 is changed, the position of touch area 360 is changed in conjunction with the position of display unit 320. Thus, the user who conducts short-range wireless communication by waving mobile terminal 400 over touch area 360 can visually recognize display unit 320 and touch area 360 simultaneously, without the need for an action to adjust the position of touch area 360 in accordance with the position of display unit 320. Because display unit 320 and touch area 360 are simultaneously visible, display unit 320 and display unit 404 of mobile terminal 400 waved over touch area 360 become simultaneously visible.

A lower section of
When display unit 320 of operation panel 300 is not readily visible to the user viewing display unit 404 of mobile terminal 400 during short-range wireless communication, the user cannot readily recognize the change in the arrangement of the icons on display unit 320.
In this respect, touch area 360 is arranged to make the display on display unit 320 more readily visible to the user viewing display unit 404 during short-range wireless communication. This allows the user to readily notice the change in the contents displayed on display unit 320, thereby smoothly proceeding with the task utilizing short-range wireless communication.
Touch area 360 is arranged adjacent to display unit 320. Because touch area 360 is arranged near display unit 320, the user can readily visually recognize both of the display on display unit 320 and the display on display unit 404 of mobile terminal 400 when he/she waves mobile terminal 400 over touch area 360.
A user typically holds mobile terminal 400 with the right hand. In operation panel 300, touch area 360 is arranged on a right-hand side of display unit 320. This can minimize the possibility that the user's hand H holding mobile terminal 400 may touch touch sensor 350 and button group 340 despite the user's intention.
In particular, in operation panel 300, button group 340 is located on a lower side of display unit 320, and touch area 360 is located on the right-hand side of display unit 320. That is, display unit 320 is adjacent to touch area 360 on a side surface (on the right side) which is different from a side surface (on the lower side) adjacent to button group 340. Touch area 360 is thus inevitably separated from button group 340. This ensures that the user's hand H holding mobile terminal 400 is prevented from touching touch sensor 350 and button group 340 despite the user's intention.
Button group 340 spaced from touch area 360 includes a start button. This can minimize the possibility that the user's hand H holding mobile terminal 400 may operate the start button despite the user's intention.
This will be more specifically described referring to
As shown in
On the other hand, in the example shown in
In the example shown in
In operation panel 300 according to the first embodiment, touch area 360 is preferably sufficiently spaced from start button 341. This can minimize the possibility that when mobile terminal 400 is waved over touch area 360, start button 341 may be operated during short-range wireless communication despite the user's intention.
Start button 341 is one exemplary button for instructing MFP 100 to perform an irreversible operation. The irreversible operation refers to an operation in which even if an instruction to stop the operation is then issued, the operation cannot return to a state before the operation. One example of the irreversible operation is a printing operation, that is, the formation of an image onto a printing sheet. Once an image is formed on a printing sheet, even if an instruction to stop the printing operation is then issued, the printing sheet does not return to its state before the formation of the image onto the printing sheet.
The same also applies to the arrangement of the software keys on display unit 320. That is, preferably, the software keys for instructing MFP 100 to perform the irreversible operation are arranged in a place distant from touch area 360 on display unit 320.

In comparison with operation panel 300 shown in
The buttons for inputting the reversible control information may be arranged near touch area 360 in operation panel 300. One example of the reversible control information is a numerical value such as the number of copies. Another example thereof is an instruction for switching the screen to be displayed on display unit 320. Even after a numerical value such as the number of copies has been set through the input of the numerical value, this setting can be changed by canceling the input without causing MFP 100 to perform the irreversible operation. Even if the screen displayed on display unit 320 is switched in response to input of an instruction for switching the screen, the display on display unit 320 is returned to that originally displayed, by subsequently inputting information for canceling the instruction, without causing MFP 100 to perform the irreversible operation.
As described above, even if the buttons for inputting the reversible control information are operated despite the user's intention, the state of MFP 100 can be returned to its original state without any substantial damage to the user. In operation panel 300 shown in

In the example shown in
As stated above, in order to more reliably prevent an unintended touch onto touch sensor 350 in operation panel 300, touch area 360 is preferably arranged adjacent to a side surface other than the upper side of touch sensor 350.
Referring to
In the case of operation panel 300 shown in
It is therefore preferred that no buttons be provided within touch area 360. In this way, operation of a button unintended by the user can be more reliably prevented in operation panel 300.
With respect to 100 according to the first embodiment, the rotation about hinge 300A (see
In MFP 100 shown in
Similarly, in MFP 100 according to the second embodiment, operation panel 300 is provided with touch area 360 together with display unit 320. Thus, when the position of operation panel 300 is changed, the position of mobile terminal 400 to be waved over touch area 360 can be changed in conjunction with the position of display unit 320, without the user having to take an action such as changing the arrangement of touch area 360, for example. The user can thus visually recognize the displays on both display unit 320 of operation panel 300 and display unit 404 of mobile terminal 400, without having to take an action such as changing the arrangement of touch area 360, for example.
With respect to MFP 100 according to the third embodiment, a state in which operation panel 300 has been removed from the main body of MFP 100 is shown as still another example of change in the position of operation panel 300. Referring to
In MFP 100 shown in
Similarly, in MFP 100 according to the third embodiment, operation panel 300 is provided with touch area 360 together with display unit 320. Touch area 360 thus moves together with display unit 320 even when operation panel 300 is removed from the main body of MFP 100. The user can thus visually recognize the displays on both display unit 320 of operation panel 300 and display unit 404 of mobile terminal 400 waved over touch area 360, without having to take an action such as changing the arrangement of touch area 360, for example.
Cable L is optional in MFP 100. That is, operation panel 300 removed from the main body of MFP 100 may be wirelessly electrically connected with the main body of MFP 100.
Although the present invention has been described and illustrated in detail, it is clearly understood that the same is by way of illustration and example only and is not to be taken by way of limitation, the scope of the present invention being interpreted by the terms of the appended claims.
