JP 2003-219353 A (published July 31, 2003) JP 2008-109316 A (published May 8, 2008) JP 9-65234 A (published March 7, 1997)

  In the above conventional technique, when the printing apparatus is connected to a display device having a plurality of input units, when the printing apparatus is turned on, the input unit connected to the printing apparatus is activated. be able to.

  However, even when the printing apparatus starts printing, the input unit that is active in the display device remains the input unit to which the printing apparatus is connected.

  The inventions disclosed in Patent Documents 1 and 3 describe a case where an image originally displayed on a display device is printed, and an image to be printed from the printing device is displayed on the display device. There is no description about the case where printing is started after transmission and display of the image on the display device.

  The invention disclosed in Patent Document 2 also describes that an event that occurs during printing by the printing apparatus is displayed on the display device, and an image to be printed from the printing device is displayed on the display device. There is no description about the case where printing is started after transmission and display of the image on the display device.

  Therefore, in Patent Documents 1 to 3, when an image to be printed is transmitted from the printing device to the display device and displayed, that is, the input unit connected to the printing device of the display device is active. In this case, it is not described when the printing apparatus starts printing.

  As described above, in the conventional description, even when the printing apparatus starts printing, the input unit that is active on the display device remains the same as the input unit to which the printing apparatus is connected. Therefore, the display during the waiting time for printing continues to display the image to be printed, and the user is likely to be bored during that time.

  The present invention has been made in view of the above problems, and an object of the present invention is to display a print waiting time in a display device in which a printing device is connected to one of a plurality of input units and display print data. It is to realize a printing apparatus or the like that can change flexibly.

  In order to solve the above-described problem, a printing apparatus according to the present invention is a printing apparatus that causes a display apparatus to display display data indicating image data to be printed by the own apparatus, and includes a plurality of input units included in the display apparatus. An output unit connected to the display unit, a display data transmission unit that transmits the display data via the output unit, and an instruction reception unit that receives a print instruction for image data corresponding to the display data transmitted by the display data transmission unit When the instruction accepting unit accepts the print instruction, the display device is input to another input unit included in the display device instead of the display data input to the input unit connected to the output unit. Control signal transmitting means for transmitting a control signal for displaying the displayed display data via the output unit.

  Also, the printing apparatus control method according to the present invention causes the display apparatus to display display data indicating image data to be printed by the self apparatus, and an output section connected to one of a plurality of input sections included in the display apparatus. A display data transmission step for transmitting the display data via the output unit, and a print instruction for image data corresponding to the display data transmitted in the display data transmission step When an instruction receiving step and a print instruction are received in the instruction receiving step, the display device receives other input provided in the display device instead of the display data input to the input unit to which the output unit is connected. And a control signal transmission step of transmitting a control signal for displaying the display data input to the unit via the output unit.

  According to the above configuration and method, the printing apparatus causes the display apparatus to display display data indicating image data to be printed by the self apparatus. The output unit of the printing apparatus is connected to one of a plurality of input units provided in the display device. When the display data is transmitted via the output unit and receives a print instruction for image data corresponding to the display data, the display input to the input unit connected to the output unit is displayed on the display device. Instead of data, a control signal for displaying display data input to another input unit included in the display device is transmitted via the output unit.

  Accordingly, when the printing apparatus receives a print instruction, the display apparatus displays the display data input to an input unit different from the input unit to which the display data output from the output unit of the printing apparatus is input.

  Therefore, it is possible to prevent display data indicating image data to be printed by the printing apparatus from being displayed on the display apparatus after the printing apparatus receives the print instruction. In addition, the display device displays not the display data input from the input unit connected to the output unit of the printing device but the display data input from another input unit. It can be changed flexibly.

  For example, consider a case where the display device is a television device and the input unit to which display data to be displayed by a control signal is input is an input unit receiving a television broadcast. When display data indicating image data to be printed by the printing apparatus is displayed on the television apparatus, when printing is started by the printing apparatus, the television broadcast is displayed on the television apparatus instead of display data indicating the image data to be printed. Therefore, after the start of printing, display data indicating image data to be printed is not displayed on the television device, but a television broadcast is displayed. Therefore, the display of the waiting time during printing can be flexibly changed. Moreover, it can suppress that a user gets bored during printing.

  The printing apparatus according to the present invention includes a printing time calculation unit that calculates a time required for printing the image data, and the control signal transmission unit calculates the printing time after starting printing of the image data. After the time calculated by the means has elapsed, a control signal for displaying the display data input to the input unit connected to the output unit may be transmitted to the display device.

  According to said structure, a printing time calculation means calculates time required in order to print image data. Then, after the printing of the image data has started, the display device displays the display data input to the input unit connected to the output unit of the printing device after the time calculated by the printing time calculation unit has elapsed. .

  Thus, only when the printing apparatus is printing, the display apparatus displays not the display data input from the input unit connected to the output unit of the printing apparatus but the display data input from another input unit.

  Therefore, even after printing is completed, the display device does not continue to display display data different from the display data output from the printing device. Therefore, the user can confirm the display data output from the printing apparatus again on the display apparatus after printing is completed, and can easily recognize the end of printing.

  Since the display data output from the printing device is displayed on the display device after printing is completed, the user can compare the display data output from other than the printing device with the display device. Can easily instruct the next processing for the printing apparatus.

  In the printing apparatus according to the present invention, the control signal transmitting unit may receive display data to be displayed instead of display data input to the input unit connected to the output unit. It is also possible to transmit a control signal designating the input unit.

  According to the above configuration, the control signal transmitted from the printing apparatus to the display apparatus is input with display data to be displayed instead of the display data input to the input section connected to the output section of the printing apparatus. Specify the input part.

  Thus, after receiving the print instruction, the printing apparatus can designate an input unit to which display data to be displayed on the display apparatus is input.

  For example, if an input unit to which display data desired by the user is input is designated as an input unit to which display data to be displayed on the display device is input, the user's desired display is displayed on the display device after printing is started. Data can be displayed.

  In the printing apparatus according to the present invention, when an error occurs in the self-apparatus during printing, the control signal transmitting means outputs display data input to an input unit connected to the output unit to the display device. Instead, a temporary change control signal for displaying display data input to another input unit included in the display device may be transmitted.

  According to the above configuration, when an error occurs in the own device during printing, the control signal transmission unit temporarily converts the input unit for inputting display data to be displayed on the display device to the output unit of the printing device. The primary change control signal to be changed is transmitted to the input unit connected to the.

  Thereby, when an error occurs in the printing apparatus, the display data output from the printing apparatus is displayed on the display apparatus. Therefore, when the printing apparatus transmits display data indicating that an error has occurred to the display apparatus, the user can recognize that an error has occurred in the printing apparatus.

  Further, the change of the input unit to which the display data displayed on the display device is input is temporary, and the display data output from the printing device is not continuously displayed on the display device. That is, the display device displays again the display data that was displayed before the error occurred. Therefore, the user can confirm again the display data displayed before the occurrence of the error after the occurrence of the error is recognized.

  The above-described effects can also be achieved when the output unit complies with the HDMI (high-definition multimedia interface) standard.

  In order to solve the above-described problem, a display device according to the present invention is a display device that includes a plurality of input units and displays display data input via at least one of the input units.

The display data may be switched to the display data input via another input unit used immediately before the input unit.

  According to said structure, an acquisition means displays the display data input via another input part instead of the said display data via the input part into which the display data currently displayed is input. When the immediately preceding switching control signal for instructing to be acquired is acquired, the switching means transmits the display data to be displayed via another input unit used immediately before the input unit to which the currently displayed display data is input. Switch to the display data entered.

  As a result, the display data to be displayed can be changed from the other input unit used immediately before the display data currently input via the input unit connected to the transmission source device of the previous switching control signal is displayed. Switch to display data input via.

  And the display data currently input via the other input part used immediately before the display data currently input via the input part connected with the transmission origin apparatus of the last switching control signal is displayed. Is considered to have been viewed immediately before the currently displayed display data.

  Therefore, the display data displayed on the display device can be switched to display data that is likely to be viewed by the user.

  Even in a data transmission system including the data transmission device and the data reception device, the above-described effects can be obtained.
