Description

Description: TECHNICAL FIELD [0001] The present invention relates to a timer timer device for an electronic device such as a home magnetic recording / reproducing device (VTR), which can set a date and time for operating or stopping the device. Is.

[Technical Background of the Invention] As is well known, for example, in a VTR, a reserved date (day of the week) for recording a broadcast program, a recording start time, a recording end time, a channel of a broadcast program to be recorded, etc. are reserved and set, and the current time is set. It has a timer function that automatically starts the recording operation when the recording start time of the set reservation date matches, and automatically stops the recording operation when the recording end time is reached. This is for convenience when the person is absent.

FIG. 5 (a) shows a VTR equipped with such a timer function.
FIG. 9 is a diagram schematically showing a conventional configuration of an operation unit and a display unit of the reservation timer device in FIG. 5, in which a time and a broadcast channel are numerically displayed on the device main body 51, and a reservation date (day of the week) is displayed by characters. Is provided. Further, below the display unit 52, a mode setting switch 53 for switching and setting the operation mode to either a reservation mode or a confirmation mode, a reservation date, a recording start time, a recording end time, a reserved broadcast channel, etc. are designated. And an operation button section 54 for operating.

When making a program reservation in this configuration, first, the mode setting switch 53 is switched to the "start" position for setting the start time in the reservation mode as shown in FIG. Set the start time and the reserved date by operating the operation button of. Next, the mode setting switch 53 is switched to the "end" position for setting the end time in the reservation mode, and then the operation button of the operation button section 54 is operated to set the end time. In FIGS. 5 (a) and 5 (b),
Tuesday as the reservation date and "7:30" as the start time
And the case where “8:00” is set as the end time.

While such a setting operation is being performed, the display unit 52
The reserved date is displayed in letters, and the start time and end time are displayed in numbers. Further, whether the reservation data is the start time or the end time is displayed by the characters "start" and "end".

On the other hand, in the operation button portion 54, as shown in FIG.
An operation button 54a is provided as a simple timer that sets only the end time and stops the recording operation of the VTR when the current time reaches this end time.
If the end time is set after operating, only the end time will be reserved. Of course, in this case as well, the set end time is displayed numerically on the display unit 52 and the special display symbol 52 indicates that the function is set as a simple timer.
Graphically displayed with 1.

On the other hand, the contents such as the broadcast date and the start time which are reserved and set as described above are displayed on the display unit 52 by setting the mode setting switch 53 to "start" like the reservation mode. From this display, the reservation data such as the start time can be confirmed.

[Problems of background art] However, in the above-described conventional reservation timer device, the operation of the mode setting switch in the reservation mode and the confirmation mode is the same, and the display form of the display section is also the same. If you can not clearly distinguish the operation and the confirmation operation and perform the setting operation such as the reservation date with the intention of the confirmation operation,
There was a problem that the reservation details that had already been set changed and had to be set again. Similarly, if you try to check the end time while functioning as a simple timer, the display on the display will have the same content as the end time in the reservation mode, so you cannot easily distinguish the two and end There was a problem that the time was mistakenly recognized.

[Object of the Invention] The present invention has been made in view of the above problems, and a first object of the present invention is that the reservation data displayed on the display unit is in any one of a confirmation mode, a reservation mode and a simple timer mode. It is an object of the present invention to provide a reservation timer device capable of easily distinguishing whether or not it is related to.

A second object of the present invention is to provide a reservation timer device capable of reliably preventing the reservation data that has already been reserved from changing from changing even if the operation button section is erroneously operated.

[Summary of the Invention] In order to achieve the first object of the present invention, a flashing control signal generating means for generating a display flashing control signal of a predetermined cycle,
Display control switch means for intermittently inputting a signal of a display character of "start" or "end" in the confirmation mode to the display means by the display blinking control signal, and causing the character display of "start" or "end" to blink. Is provided.

Further, in order to achieve the second object, an input control switch means for prohibiting reception of an output signal from the operation button for reservation setting in the confirmation mode is provided.

[Examples of the Invention] Hereinafter, the present invention will be described based on illustrated examples.

FIG. 1 is a block diagram showing an embodiment of a reservation timer device according to the present invention, and 1 has operation buttons for setting a current time, a reservation date, a recording start time, a recording end time, a channel of a broadcast program, and the like. , An input unit as a reservation data setting means including a mode setting switch for switching and setting the operation mode between the reservation mode and the confirmation mode. Reference numeral 2 discriminates the operation mode set in the input unit 1. In the reservation mode, the reservation data regarding the program reservation such as the reservation date set by the operation button of the input unit 1 is stored in the storage device 3, and in the confirmation mode. This is a control unit that reads out the reservation data stored in the device 3 and displays it on the display 8 described later. Reference numeral 4 is a display control unit for controlling the display operation of the display unit 5, 5 is a blinking control unit for blinking the display content on the display unit 8, and 6 and 7 are display data of the display unit 8 received from the display control unit 4. A display drive unit for converting into a signal for driving a display segment. The display drive unit 6 selectively drives one of a plurality of digits of display elements in the display unit 8, and one display drive unit 7 is selectively driven. Drive each segment of the digit display element. Reference numeral 8 denotes a display device as a display means, and here, a 4-digit display element for numerically displaying the reserved start time and end time and a 1-digit display element for numerically displaying the channel of the reserved broadcast program And a 7-digit character display element that displays the reserved date (Monday to Sunday) as a character, and "Start" and "End" character displays that indicate whether the start time is being set or the end time is being set. And an element.

FIG. 2 is a block diagram showing in more detail a portion indicated by a broken line A in FIG. 1, that is, a portion relating to a main part of the present invention. In the input portion 1, an operation circuit 11 for setting reservation data and an operation mode. Is provided separately from the operation circuit 12 used for setting, and the reservation data set in the operation circuit 11 has no confirmation mode set in one operation circuit 12, and Only when it is recognized by the mode discriminating circuit 23, it is inputted to the reservation data control circuit 22 through the input control switch 21, and is configured to be stored in the storage device 3 under the control of this reservation data control circuit 22 and is displayed. It is input to the control circuit 41 of the control unit 4 and is sent to the conversion circuit 44 by the display control of the control circuit 41.
In FIG. 4, the signal in the digit direction and the signal in the segment direction are decomposed and sent to the display drive units 6 and 7, respectively, so that numerical display or character display is performed.

Further, the blinking control section 5 is provided with a blinking signal generating circuit 51, and when the confirmation signal 2a of the confirmation mode is inputted from the mode discriminating circuit 23, the blinking control signal 5a which is intermittent in a predetermined cycle is generated. The blinking control signal 5a is input to the control input of the display control switch 43 connected to the output side of the display control circuit 42 which receives the character display data of "end" and "start" from the reservation data control circuit 22, and "start" Or "end" character display data is intermittently input to the conversion circuit 44 to blink the "start" or "end" character.

In the above configuration, when making a program reservation, first, the operation circuit 12 switches the operation mode to the reservation mode, and further sets the mode of the time to be set to "start time" or "end time". Next, reservation data such as a reservation date is set in the operation circuit 11. Then, the mode discrimination circuit 23 recognizes the set operation mode as the reservation mode and sets the recognition signal 2a to the "L" level. Then, the input control switch 21 is turned on, the reservation data set by the operation circuit 11 is sent to the reservation data control circuit 22, and is stored in the storage device 3 under the control of this control circuit 22 and the display control circuit 41 is set. It is input to the conversion circuit 44 via the conversion circuit 44, and is converted into a display signal in the digit direction and a display signal in the segment direction, and the display drive units 6 and 7
Are input respectively. As a result, the set reservation data is displayed on the display 8. At this time, when the operation circuit 11 performs an operation indicating that the reservation data is “start time”, a signal for displaying the character “start” is displayed on the display control switch 43 via the display control circuit 42.
However, the blinking signal generation circuit 51 does not generate the blinking control signal because it is in the reservation mode. Therefore, the switch 43 continuously maintains the ON state. Therefore, the signal for displaying "start" is continuously input as it is to the conversion circuit 44 via the switch 43. As a result, the display element for displaying "start" on the display 8 is continuously lit as shown in FIG. 4 (a).

However, when the confirmation mode is set in the operation circuit 12, the mode discrimination circuit 23 recognizes this and sets the recognition signal 2a to the "H" level as shown in FIG. 3 (a) to turn off the input control switch 21. At the same time, the blinking signal generating circuit 51 is activated, and the blinking control signal 5a intermittently generated at a predetermined cycle is generated from the circuit 51 as shown in FIG. 3 (b). Then, the reservation data related to the program reservation from the operation circuit 11 is blocked by the switch 21 and is not input to the reservation data control circuit 22. Flashing control signal 5 at the same time
The display control switch 43 is turned on and off at a predetermined cycle by a, and the signal 4b for displaying "start" or "end" is intermittently input to the conversion circuit 44 as shown in FIG. 3 (C). Will be done.

As a result, the “start” or “end” character display blinks, and it becomes possible to clearly identify that the confirmation mode is currently set. Further, even if some operation is performed on the operation circuit 11, the stored content of the storage device 3 does not change because the switch 21 is off.

In this case, the mode discrimination circuit 23 sets the mode recognition signal 2a to the "H" level even when the function selection as the simple timer is made in the operation circuit 12. As a result, when checking the end time during operation as a simple timer, the graphic display indicating that it is operating as a simple timer flashes, and it can be clearly distinguished from the setting state of the end time of the reservation data. become able to.

FIG. 4 (b) shows an example of the display contents of the display 8 when confirming the end time, and FIG. 4 (C) shows the display contents when confirming the end time when functioning as a simple timer. An example is shown.

In this embodiment, the reservation data is the reservation date,
Although the recording start time, the end time, and the channel data of the broadcast program can all be set, the present invention can be applied to at least a timer device for setting the end time of the start time. Further, although the control of the recording operation of the VTR is taken as an example, it can be used for all the electronic devices or the like that require the start time or the end time of the operation to be set and the confirmation thereof.

[Effects of the Invention] As described above, in the first invention of the present invention, since the character display of "start" or "end" displayed on the display means in the confirmation mode is made to blink, a special display element is added. It becomes possible to easily distinguish between the reservation mode and the confirmation mode without doing so, and it is possible to prevent the program reservation operation from being mistakenly performed in the confirmation mode. In the second invention,
Since the reception of the reservation data is forcibly prohibited in the confirmation mode, it is possible to reliably prevent the already set reservation data from being changed even if the program reservation operation is mistakenly performed in the confirmation mode.
