Description

  The present invention relates to a display device that displays a state for notifying a state inside the device and a control method therefor.

  The display device displays a status display for notifying the internal status of the device, an operation display for notifying the operated content, an error display for notifying the error content that has occurred, and the like on a display unit provided in the device body. It improves usability. For example, Patent Document 1 describes a printer device equipped with a display device that employs a liquid crystal device as a display unit. This conventional display device prevents a liquid crystal device from displaying an unintelligible character immediately after the device main body is turned on, thereby preventing the operator from misidentifying or anxious about the failure. Is.

  By the way, for the purpose of improving operability and visibility, the display device not only displays information on a display unit provided in the device body, but also has an interface that can connect a monitor device to the outside, and has a large screen monitor device. There are many things that can display information.

In addition, the display device continues to output images to a monitor device connected to the outside when there is no constant operation within the predetermined time or when there is no change in the state of the device. In many cases, the displayed display unit is set to a non-display state so as to save power of the apparatus main body and suppress a reduction in the lifetime of the display unit. This non-display state can be canceled when a certain operation key is pressed.
JP 11-344957 A

  When an arbitrary operation key is pressed to cancel the non-display, the key operation does not indicate an operation that means the original operation key is pressed, but an instruction for redisplaying from non-display. .

  When the display unit is not displayed, the operator cannot recognize the state of the device body, and the original function of the operation key is activated by the operation key pressed in the non-display state. This is because there is a possibility of causing an unnecessary operation.

  The printing unit 102 includes a thermal head, various motors, a gear group, a roller group, a sensor group, and the like in order to print image data on recording paper stored in a paper cassette according to an instruction from the control unit 106. Yes. The printing unit 102 is provided with a slot for mounting an ink cassette of a type corresponding to the size of the recording paper to be printed.

  The interface unit 103 is an interface for connecting to the PC 11 and the DSC 12, and includes a USB port. The memory card slot unit 104 is a slot into which a memory card is inserted. In the first embodiment, the memory card slot portion 104 employs a memory card slot (registered trademark) that can be mounted. However, another memory card may be mounted. The image output unit 105 is provided with a video output connector, converts display data from the control unit 106 into an NTSC display signal, and outputs it from the video output connector.

  As shown in FIG. 4, the control unit 106 performs overall control of the entire apparatus main body 100, and includes a processing unit 106a, a memory unit 106b, a timer (A) 106c that functions as a first timer, And a timer (B) 106d functioning as a timer. The control unit 106 is used as a CPU (Central Processing Unit), a control circuit for controlling the CPU, a ROM (Read Only Memory) in which programs, various settings and messages to be displayed are stored, and a program work area. RAM (Random Access Memory). That is, the ROM and RAM function as the memory unit 106b, and the CPU executes a program stored in the ROM that is the memory unit 106b, thereby functioning as the processing unit 106a that performs processing such as printing and processing. To do.

  In the first embodiment, a flash memory is used as a ROM for storing a program so that it can be easily updated. The stored program is stored in the flash memory in a compressed state, and is expanded on the RAM and executed by the CPU in the initial operation when the power is turned on.

  In addition, the timer (A) 106c and the timer (B) 106d that measure the predetermined time may be soft timers that are measured by executing a program or hardware timers that are configured by hardware. The timer (A) 106c and the timer (B) 106d are validated by the processing unit 106a, and measurement is started by being activated by the processing unit 106a. The timer (A) 106c and the timer (B) 106d can be stopped, restarted, or invalidated as necessary by the processing unit 106a.

  The operation of the printer apparatus 10 according to the first embodiment of the present invention configured as described above will be described with reference to FIGS. FIG. 5 is a flowchart showing an operation in which the printer device of the printer system according to the first embodiment of the present invention shifts to the standby mode. FIG. 6 is a flowchart showing an operation of the printer device transitioning to the stop mode. FIG. 7 is a diagram showing a display in the standby mode. FIG. 8 is a table showing the event. FIG. 9A to FIG. 9D are diagrams showing examples of display. FIG. 10 is a diagram showing a display in the stop mode. FIG. 11 is a flowchart showing an operation for releasing the stop mode. FIG. 12 is a diagram showing a display when the stop mode is canceled.

  As shown in FIG. 1, a monitor device 14 is connected to the printer body 10 in the printer device 10, and an operator can display image data captured by the DSC 12 with a display unit 101 having a small screen size or a display unit 101. It is assumed that printing is performed while observing the monitor device 14 having a considerably larger screen size than the monitor device 14.

  As shown in FIG. 5, the processing unit 106a first activates the display unit 101 when the power is turned on. That is, the processing unit 106a enables display on the LCD of the display unit 101 and turns on the backlight (S100). The processing unit 106a validates the timer (B) 106d (S110). Then, the timer (A) 106c is validated (S120). By specifying and enabling the timer (A) 106c or the timer (B) 106d, the time can be measured. Then, the timer (A) 106c is activated by specifying 10 minutes as the maximum no-operation time T1 (first time) until the sleep message is displayed, so that time is set and measurement is started (S130). The time set in the timer (A) 106c is the value of the maximum no-operation time T1 until the sleep message display input by the operator operating the setting screen in advance.

  The processing unit 106a determines whether or not the measurement of the timer (A) 106c has timed out exceeding the maximum no-operation time T1 until the sleep message is displayed (S140). When the timer (A) 106c times out, the processing unit 106a outputs a sleep message for notifying display stop to the display unit 101 and the image output unit 105 and shifts to the standby mode (S150).

  For example, the operator connects the PC 11 and DSC 12 to the interface unit 103 or attaches the memory card 13 to the memory card slot unit 104 to transfer the image data to the memory unit 106 b and display the transferred image data. Assume that the image is output to the unit 101 and is output to the monitor device 14 via the image output unit 105. In this state, if any event in the event group described later in detail does not occur within the maximum no-operation time T1 until the sleep message is displayed, as shown in FIG. Since the operation has continued, the LCD monitor is turned off. When any button is pressed, the sleep message is displayed on the display unit 101 and the monitor device 14. As a result, the operator who is observing the display unit 101 can understand that the display is stopped by no operation or the like even by the operator who is observing the monitor device 14. Therefore, it is possible to prevent misrecognition or anxiety of failure by reliably transmitting the state of the apparatus to the operator.

  If it is determined in S140 that the timer (A) 106c has not timed out, it is determined whether or not an event has occurred (S160). Here, the event will be described in detail with reference to FIG.

  The table shown in FIG. 8 is stored in the memory unit 106b. When an event occurs as the processing in S150, the processing unit 106a determines whether the generated event is included in the event group of this table.

  The events include “internal state transition”, “operation key pressed”, “file read complete”, “card scan complete”, “error occurred”, and the like.

  The “internal state transition” is, for example, a state in which the printing unit 102 transitions from an idle state where no printing operation is performed to a printing state, or a transition from a printing state to a state in which page printing is completed and a sheet is discharged. Or when an ink cassette of a different type from the loaded recording paper is loaded, or when the memory card 13 is inserted or removed. For example, when a plurality of image data are printed, it is necessary to display the number of printed sheets counter every time one sheet is printed. Therefore, an event of “internal state transition” occurs every time one sheet is printed. .

  “Pressing of the operation key” is when the operation key 110 provided on the apparatus main body 100 is pressed or when the remote controller R is operated. “File read complete” is when the memory card 13 storing the image data captured by the DSC 12 or the like is loaded in the memory card slot 104 and the image data file has been read. “Card scan complete” is a case where the operation when the image data stored in the memory card 13 is searched or the card information of the memory card is acquired is completed. “Error occurrence” is a case where various errors have occurred, from a minor error to a severe error. “Displaying messages such as error, operation guide, warning (notification)” is when an error occurs or a message such as an operation guide or warning (notification) is being displayed.

  In this way, it is determined whether or not an event has occurred. If not, the process proceeds to S140.

  If it is determined that an event has occurred, the processing unit 106a executes processing according to the content of the event. At this time, the same display content is displayed on the display unit 101 and the monitor device 14 (S170). For example, when the “print” key is pressed, the selected image data is printed. At that time, a display process is performed in which the message shown in FIG. 9A is temporarily displayed for a few seconds and then deleted. When an event occurs as “error occurrence”, screen display processing corresponding to the content of each error is performed. For example, when a paper cassette containing recording paper is removed, as shown in FIG. 9B, a message to that effect is displayed on the display unit 101 and “cancel” is displayed. This message is a message for requesting a response to be displayed until the operator deletes “Cancel” on the display unit 101 by pressing the “Determine” key in order to reliably convey the content of the message to the operator. When the paper cassette storing the recording paper is removed, it is handled in the same manner as the case where the type of the ink cartridge installed in the printing unit 102 does not match the size of the recording paper stored in the paper cassette. The message is as shown in (B).

  When the memory card slot 104 is removed, a message as shown in FIG. 9C is temporarily displayed for a few seconds and then deleted. Furthermore, when an error that is difficult to recover occurs, such as when the fan motor fails during printing, the message is not deleted until the error is cleared and the device is restarted. Display processing is performed.

  Thus, when an event occurs, processing corresponding to the event is performed. Since the sleep message is not displayed on the display unit 101 and the monitor device 14, the output to the display unit 101 and the monitor device 14 is continued and the same content is displayed. Therefore, the operator can operate while observing either the display unit 101 or the monitor device 14.

  As shown in FIG. 5, the processing unit 106a stops the timer (A) 106c and proceeds to S130 (S180).

  In S150, the sleep message is displayed on the display unit 101 and the monitor device 14, and the processing unit 106a that has entered the standby mode starts the timer (B) 106d as shown in FIG. The maximum no-operation time T2 (second time) is set, and measurement is started (S190). The time set in the timer (B) 106d is the value of the maximum no-operation time T2 until the non-display execution input by the operator operating the setting screen in advance.

  The processing unit 106a determines whether or not the measurement of the timer (B) 106d has timed out exceeding the maximum no-operation time T2 until execution of non-display (S200). When the timer (B) 106d times out, the processing unit 106a transitions to a stop mode in which the display unit 101 is inactivated and put into a non-display state. That is, the LCD of the display unit 101 is disabled and the backlight is turned off (S210).

  As shown in FIG. 10, by setting the display unit 101 to the non-display state, it is possible to save power of the apparatus main body 100 and to suppress a reduction in the lifetime of the display unit 101. At this time, the processing unit 106a continues to display the sleep message on the monitor device 14. This is because there is no problem for an operator observing the monitor device 14 whether the apparatus main body 100 is in the standby mode and the display unit 101 is displaying a sleep message or is in a non-display state in the stop mode. Because. Conversely, if the image output to the monitor device 14 is stopped when the apparatus main body 100 is in the stop mode, the operator may misunderstand that the monitor device 14 has failed. desirable.

  If it is determined in S200 that the timer (B) 106d has not timed out, it is determined whether or not an event has occurred (S220). In S220, it is determined whether or not an event has occurred. If not, the process proceeds to S200.

  If an event occurs in S220, the output to the display unit 101 and the monitor device 14 is redisplayed by returning to the display before the sleep message is output from the sleep message (S230). This re-display is performed by outputting the contents of the screen memory area stored in the memory unit 106 b in the control unit 106 to the display unit 101 and the image output unit 105.

  Then, it is determined whether or not the generated event is “operation key pressed” (S240). This is because the operation key 110 depression or operation of the remote controller R, which is the event “operation key depression”, is due to the operator instructing to cancel the standby mode in which the sleep message is displayed. This is because the user does not instruct the operation that is meant by pressing each operation key 110 or operating the remote controller R. Accordingly, when the generated event is “operation key pressed”, the process proceeds to S260 without performing processing according to the content of the event.

  In S240, if the event that has occurred is not "pressing the operation key", processing corresponding to the content of the event is performed (S250). For example, when an event “file read complete” occurs when a file of image data is read from a memory card mounted in the memory card slot 104 and the read is completed, the image data read into the display unit 101 is completed. The thumbnail display is output to the display unit 101 and the image output unit 105, and the input of the operator is awaited.

  As described above, since the display of the sleep message is changed to the display corresponding to each event due to the occurrence of the event, even if the operator observes either the display unit 101 or the monitor device 14, the processing of the event is performed. Never miss a result.

  Then, the processing unit 106a stops the timer (B) 106d, and proceeds to S130 shown in FIG. 5 (S260).

  In the first embodiment, both the transition to the standby mode due to the timeout of the timer (A) 106c and the transition to the stop mode due to the timeout of the timer (B) 106d are based on the occurrence of the event shown in FIG. There are the same conditions, but different conditions are also possible.

  Next, a case where the processing unit 106a in the stop mode cancels the stop mode will be described. It is assumed that the printer apparatus 10 has been in a non-display stop mode from S210 shown in FIG.

  As shown in FIG. 11, it waits for an event to occur (S300). If an event occurs, the display unit 101 is activated and redisplayed (S310). That is, after the processing unit 106a validates the display on the LCD of the display unit 101 and turns on the backlight, the contents of the screen memory area stored in the memory unit 106b in the control unit 106 are displayed on the display unit 101 and By outputting to the image output unit 105, activation and re-display are performed as shown in FIG.

  It is determined whether or not the generated event is “operation key pressed” (S320). This is the same reason as the determination in S240 shown in FIG. In S320, if the generated event is “operation key pressed”, the process proceeds to S130 only by redisplaying. If the generated event is not “depressing the operation key”, processing corresponding to the content of the event is performed (S330), and the process proceeds to S130 shown in FIG.

  Thus, even if the operator observing the monitor device 14 presses the operation key 110 to cancel the sleep message, the function that is started when the operation key 110 is pressed is not executed. Since an arbitrary operation key 110 is pressed, it is possible to prevent an undesired function from operating.

(Embodiment 2)
A display device according to the second embodiment will be described with reference to FIGS. 13 and 14 by taking a printer device as an example. FIG. 13 is a block diagram showing the configuration of the control unit of the printer apparatus according to the second embodiment of the present invention. FIG. 14 is a flowchart for explaining the operation of the printer apparatus according to the second embodiment of the present invention. .

  As shown in FIG. 13, the printer apparatus according to the second embodiment includes a control unit 106 that includes two timers, timer (A1) 106e and timer (A2) 106f, as timer (A). It is. The timer (A1) 106e and the timer (A2) 106f are validated by the processing unit 106a, and the value of the maximum no-operation time T1 until the sleep message is displayed by the operator operating the setting screen in advance. Is set. The timer (A1) 106e and the timer (A2) 106f start measurement when activated by the processing unit 106a, and notify the processing unit 106a when time is up. Further, it is reset by being invalidated by the processing unit 106a.

  Control of the two timers (A1) 106e and timer (A2) 106f will be described in detail with reference to FIG.

  As shown in FIG. 14, the processing unit 106a activates the display unit 101 when power is first turned on. That is, the processing unit 106a activates the display on the LCD of the display unit 101 as valid, and turns on the backlight (S400). The processing unit 106a sets the timer (B) 106d by enabling 1 minute as the maximum no-operation time T2 until execution of non-display (S410). Then, either the timer (A1) 106e or the timer (A2) 106f is validated, but the timer (A1) 106e is validated because it is the first operation (S420).

  Next, since the timer (A1) 106e is validated in S420, 10 minutes is set as the maximum no-operation time T1 until the sleep message display by starting the timer (A1) 106e. Is started (S430). The time set in the timer (A1) 106e is the value of the maximum no-operation time T2 until the non-display execution input by the operator operating the setting screen in advance.

  The processing unit 106a determines whether the timer (A1) 106e has timed out beyond the maximum no-operation time T1 until the sleep message is displayed (S440). If it is determined that the timer (A1) 106e has not timed out, it is determined whether or not an event has occurred (S450). In S450, it is determined whether or not an event has occurred. If no event has occurred, the process proceeds to S440.

  If it is determined in S450 that an event has occurred, the processing unit 106a executes processing according to the content of the event (S460). The execution in S460 is the same processing as S170 shown in FIG.

  Then, it is determined whether or not the currently valid timer is the timer (A1) 106e (S470). In this case, since the enabled timer is the timer (A1) 106e, the process proceeds to S480.

  In S480, the timer (A2) 106f is validated. Then, the timer (A1) 106e is invalidated and the process proceeds to S430 (S490). If an event occurs within the maximum no-operation time T1 until the sleep message is displayed, the sleep message is not displayed on the display unit 101 and the monitor device 14, and therefore the output to the display unit 101 and the monitor device 14 is continued. The same contents are displayed. Therefore, the operator can operate while observing either the display unit 101 or the monitor device 14.

  As described above, in the second embodiment, the timer (A1) 106e and the timer (A2) 106f are used. As in the first embodiment, time monitoring is performed only by the timer (A) 106c. In this case, the timer (A) 106c may time out when the processing unit 106a performs processing according to the event content in S170 shown in FIG. When the timeout at this time is stored in the processing queue or the like, the timeout is notified to the processing unit 106a even after resetting by disabling the timer (A) 106c in S180. In S140, an affirmative determination is made, and the sleep message is output to the display unit 101 and the image output unit 105 in S150 despite the occurrence of an event.

  In the second embodiment, when the processing unit 106a performs processing according to the content of the event in S460 shown in FIG. 14, the timer (A1) 106e times out, and this time-out is processed. Assume that a time-out is notified to the processing unit 106a after being stored in a queue or the like and the timer (A1) 106e is invalidated in S490. In this case, even if an affirmative determination is made in S440, it is determined whether the timer enabled in S500 is the same as the timer that has timed out. In other words, in this case, the effective timer is the timer (A2) 106f, and the timer that has timed out is the timer (A1) 106e, so the sleep message is output to the display unit 101 and the image output unit 105. Without executing the process, the process returns to S430, and this time the timer (A2) 106f is started. If it is determined in S500 that the timers coincide with each other, the processing unit 106a outputs a sleep message informing the display unit 101 and the image output unit 105 that the display is stopped and shifts to a standby mode (S510).

  In S440, it is determined whether or not a timeout has occurred. If no timeout has occurred, it is determined whether or not an event has occurred in S450. If an event has occurred, the contents of the event are processed by the processing unit 106a in S460. The process according to is executed. It is determined whether or not the timer valid in S470 is the timer (A1) 106e, but since the timer (A2) 106f is validated in S480, the process proceeds to S520.

  In S520, the timer (A1) 106e is activated. Then, in S530, the timer (A2) 106f is invalidated, the process proceeds to S430, and this time the timer (A1) 106e is started.

  As described above, in the second embodiment, the timer (A1) 106e and the timer (A2) 106f are alternately used, and when the event does not occur within the maximum no-operation time T1 until the sleep message is displayed, The timer is compared with the timer that measures the maximum no-operation time T1 until the display of the sleep message, and an event occurs by outputting the sleep message to the display unit 101 and the image output unit 105 only when they match. It is possible to prevent the passing of a sleep message.

  Since the present invention can prevent the operator from being misunderstood or worried about the failure by reliably transmitting the state of the device to the operator, the display unit provided on the device main body and the external It is suitable for a display device that performs display on a monitor device connected to each other and a control method thereof.
