Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an electronic device that operates a main body based on a program stored in a rewritable memory such as an EEPROM built in the main body, and particularly to an electronic device such as a television and a video.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, various electronic devices such as a television receiver (hereinafter, simply referred to as a television), a video, and the like are configured so as to be able to adjust a portion which is affected by a variation in accuracy of electronic components constituting a main body. Have been. For example, the television is configured such that the color and brightness of the screen, the resonance frequency of the receiving unit for the selected channel, and the like can be adjusted. Electronic devices are adjusted at the factory before shipment before shipment.

A general electronic device stores an operation control program for instructing an operation in an adjustment mode for performing the above-described adjustment and a general mode in which a user uses the apparatus main body in a memory. The control unit operates the main body based on the operation control program.

In a factory, an operator operates the apparatus main body in an adjustment mode to adjust each part before shipping.

By the way, in order to reduce the cost of the apparatus main body, it is required to reduce the labor required for adjustment work. In response to this demand, for example, when the AC cord of the main body is connected to the outlet (when power supply to the main body is started), the main switch of the main body is turned on and each part of the main body is connected. A method of supplying power and storing an adjustment mode switching program instructing to operate the apparatus main body in the above adjustment mode in a memory was considered. In this method, the operator can perform the adjustment immediately because the apparatus operates in the adjustment mode simply by connecting the AC cord to the outlet. As in the related art, the operator does not need to turn on the main switch of the apparatus main body or perform the operation of switching the state of the main body to the adjustment mode.

[0006] Thus, the labor of the operator involved in the adjustment work can be reduced, and the cost of the apparatus main body can be reduced.

[0007]

[Problems to be solved by the invention]

 However, in the above method, unless the adjustment mode switching program stored in the memory is erased, the adjustment mode switching program is executed every time a user connects the AC cord of the main body to an outlet after shipment, and the apparatus main body is adjusted. Mode.

Normally, since the user uses the apparatus main body in the general mode, it is necessary to perform an operation for switching the state of the apparatus main body from the adjustment mode to the general mode, which deteriorates the operability of the user. was there.

This problem can be solved by erasing (or invalidating) the adjustment mode switching program from the memory before shipment, but it takes time and effort to erase the adjustment mode switching program. The effect of reducing the cost of the main unit cannot be obtained.

A technique for invalidating a changed portion of a program stored in a ROM due to a bug or the like has been proposed in Japanese Patent Application Laid-Open Nos. 1-199232 and 60-69743. Also, recently, a memory such as an EEPROM that can be partially rewritten electrically has been put into practical use, so that it is technically possible to erase or invalidate a part of the stored content of the memory. is there.

An object of the present invention is to provide an electronic device in which the labor required for adjusting the main body is reduced and the cost of the main body is reduced without lowering the operability.

[0012]

[Means for Solving the Problems]

 The electronic device of the present invention has the following configuration in order to solve the above-mentioned problem. (1) A memory storing an operation control program for instructing the operation of the apparatus main body in an adjustment mode for adjusting each part of the apparatus main body and a general mode during normal use of the apparatus main body, and the above-mentioned memory stored in the memory. An electronic device comprising: a control unit that operates the apparatus main body based on the operation control program; wherein the memory further operates the apparatus main body in the adjustment mode when power supply to the apparatus main body is started. The control section deletes the adjustment mode switching program stored in the memory from the memory at a predetermined timing.

(2) The adjustment mode switching program is a program that includes an instruction to execute adjustment of the apparatus main body in the adjustment mode.

(3) The predetermined timing is when the adjustment program is executed.

(4) The predetermined timing is when a predetermined input operation is performed on the main body.

(5) The memory is an EEPROM.

In the above configuration, when the supply of power to the apparatus main body is started, the adjustment mode switching program stored in the memory is executed, and the apparatus main body operates in the adjustment mode for adjusting each unit. In this case, when the AC cord of the apparatus body is connected to the outlet, the apparatus body automatically operates in the adjustment mode, so that the operator can immediately start adjustment of each part of the apparatus. Therefore, the labor required for this adjustment work is reduced, and the cost of the apparatus main body can be reduced.

The adjustment mode switching program is erased from the memory at a predetermined timing. The predetermined timing may be a timing at which the adjustment mode switching program is executed or a timing at which a predetermined input operation is performed on the apparatus main body. This predetermined timing may be any timing as long as it is after adjustment of each unit of the apparatus main body and before the user starts using the apparatus.

As a result, the adjustment mode switching program is not executed after the user starts using (the adjustment mode switching program is already erased from the memory), and the operability of the user is not reduced. .

The adjustment mode switching program may include an instruction to execute adjustment of each unit of the apparatus main body in the adjustment mode. In this way, the total number of adjustment items performed by the operator can be reduced. Therefore, the labor required for adjusting the apparatus main body can be further reduced, and the cost of the apparatus main body can be further reduced.

Further, by using the EEPROM as the memory, the adjustment mode switching program can be electrically and easily erased, so that there is no problem that the cost of the apparatus body is increased.

[Embodiment of the invention]

 Hereinafter, a television receiver according to an embodiment of the present invention will be described.

FIG. 1 is a diagram showing a configuration of a television receiver according to an embodiment of the present invention. A television receiver 1 (hereinafter, simply referred to as a television) of this embodiment has a control unit 2 for controlling the operation of the main body, and a storage for storing a program for operating the main body of the apparatus and data generated during the operation of the main body. A receiver 3 for receiving a broadcast signal of a channel selected from analog broadcast signals (NTSC analog broadcast signals) received by the antenna 11, and a video based on the broadcast signals and the like received by the receiver 4. A display unit 5 for displaying, an audio output unit 6 for outputting audio based on a broadcast signal or the like received by the reception unit 4, a channel switching of the broadcast signal received by the reception unit 4, and an audio output from the audio output unit 6 An operation unit 7 for performing an input operation on the apparatus main body, such as a size of the apparatus, a remote control reception 8 for receiving a signal transmitted from the remote control apparatus 10 by radio waves or infrared rays; A power supply circuit 9 for supplying power to each part of the body.

The storage unit 3 has an EEPROM 3a for storing a program for operating the apparatus main body, and a RAM 3b for temporarily storing data generated during operation of the main body (see FIG. 2). . The details of the program stored in the EEPROM 3a will be described later. The display unit 5 has a well-known CRT, and can display an image based on the image signal received by the receiving unit 4, a color bar, and the like. The operation unit 7 has a channel key, a volume control key for adjusting the volume of the sound output from the sound output unit 6, a main switch of the apparatus main body, and the like. Remote control device 10 transmits a channel switching signal for instructing switching of a receiving channel, a volume control signal for instructing a change in the volume (volume) of audio output from audio output unit 6, and the like. The power supply circuit 9 is connected to an AC cord 9a. Power can be supplied to the main body by connecting an AC plug 9b provided at the end of the AC cord 9a to an outlet (for example, an AC 100V outlet).

As shown in FIG. 2, the EEPROM 3a of the storage unit 3 stores a main program 21, a general mode program 22, an adjustment mode program 23, and an adjustment mode switching program 24 (see FIG. 2). However, the adjustment mode switching program 24 is erased from the EEPROM 3a before shipment as described later. The area in which the adjustment mode switching program 24 in the EEPROM 3a after erasing is stored becomes an empty area. The general mode program 22 is a program for displaying an image of a program broadcast on a channel received by the receiving unit 4 on the display unit 5 and controlling an operation of outputting an audio signal from the audio output unit 6. Is a program executed when a user watches a program being broadcast. The adjustment mode program is a program that is executed when adjusting each part of the main body. For example, it is a program that displays a color bar on the display unit 5 when adjusting the color tone and brightness of the screen. The general mode program 22 and the adjustment mode program 23 are technologies used in known televisions, and will be briefly described here.

Hereinafter, an operation of the television 1 of the embodiment will be described.

[0027] The television 1 of this embodiment has a control unit 2 that is powered by the main unit, that is, when the AC plug 9b is connected to an outlet, regardless of the on / off state of the main switch. And a configuration for supplying power to the storage unit 3. The control unit 2 operates regardless of the on / off state of the main switch when power is supplied to the apparatus main body.

When the main switch is off, power is not supplied to the receiving unit 4, the display unit 5, and the audio output unit 6, and the power consumption of the apparatus body when the main switch is off is Negligible.

When the power supply is started, that is, when the AC plug 9b is connected to the outlet of the commercial power supply (100 V), the television 1 executes the main program shown in FIG. . Here, a description will be given below assuming that the adjustment mode switching program 24 is stored (not erased) in the EEPROM 3a.

The control unit 2 reads out the adjustment mode switching program 24 stored in the EEPROM 3a to the RAM 3b (s1). The control unit 2 executes the adjustment mode switching program 24 read into the RAM 3b (s2).

The adjustment mode switching program executed in s2 will be described. FIG. 4 is a flowchart showing the adjustment mode switching program.

The main switch of the apparatus body is turned on (s 11). As a result, in the television 1, the supply of electric power to each unit of the apparatus main body, such as the receiving unit 4, the display unit 5, and the audio output unit 6, is started. Next, the adjustment mode program 23 is read into the RAM 3b (s12), and the adjustment mode program is executed (s13).

The adjustment mode program 23 is a program for outputting an image and a sound in accordance with the designated adjustment item and instructing an operation of receiving an adjustment value input for the adjustment item. For example, when the designated adjustment item is the color of the CRT screen on the display unit 5, the program displays a color bar on the CRT screen of the display unit 5. Since the color bar is displayed on the screen of the CRT, the operator (the person who performs the adjustment work) can easily adjust the color tone.

As described above, the adjustment mode program 23 is a known program that assists an operator in performing an adjustment operation.

When the adjustment of each part of the apparatus main body by the operator is completed, the adjustment mode program 23 is terminated, the adjustment mode switching program 24 stored in the EEPROM 3a is deleted (s14), and the main switch is turned off ( s15) This process is completed. Thus, in the EEPROM 3a, the area where the adjustment mode switching program 24 is stored becomes a free area.

Since the adjustment mode switching program 24 is stored in the EEPROM 3a, it can be electrically erased.

Further, since the television 1 reads the adjustment mode switching program 24 stored in the EEPROM 3a into the RAM 3b and executes the same, the adjustment mode switching program 24 stored in the EEPROM 3a can be deleted.

Returning to FIG. 3, when the execution of the adjustment mode switching program 24 relating to s 2 is completed, the main program 21 waits for the main switch to be turned on (s 3). The mode program 22 is read into the RAM 3b (s4) and executed (s5).

When the general mode program 22 receives an input for selecting the adjustment mode, the general mode program 22 terminates the program, reads the adjustment mode program 23 into the RAM 3b, and instructs the execution of the adjustment mode program 23. have. On the other hand, when there is an input for selecting the general mode, the adjustment mode program 23 performs a termination process of the program, reads the general mode program 22 to the RAM 3b, and instructs the execution of the general mode program 22. have .

The general mode program 22 receives the program broadcast on the designated channel by the receiving unit 4, displays the video of the program on the CRT screen of the display unit 5, and displays the program of the program. As described above, the television 1 according to the present embodiment starts the execution of the general mode program 22 in s5, and then selects the adjustment mode, as described above. If there is an instruction to perform the adjustment, the general mode program 22 is terminated and the adjustment mode program 23 is executed. Conversely, if there is an instruction to select the general mode (adjustment completion input) while the adjustment mode program 23 is being executed, the adjustment mode program 23 is executed. And the general mode program 22 is executed.

When the main switch of the apparatus main body is turned off, the general mode program 22 or the adjustment mode program 23 that is being executed at this time is terminated by an interrupt process, and the process returns to s3.

When the AC plug 9b is unplugged from the outlet, the supply of power to the apparatus main body stops, and the control unit 2 also stops operating.

In the above description, the operation in the case where the television 1 to which the AC plug 9b is connected to the outlet stores the adjustment mode switching program 24 in the EEPROM 3a, but the adjustment mode switching program 24 is stored in the EEPROM 3a. Otherwise, it operates as follows.

The television 1 executes the main program 21 as described above when the supply of power to the apparatus main body is started.

Here, since the adjustment mode switching program 24 has already been erased from the EEPROM 3a, the adjustment mode switching program 24 is not read in s1. Therefore, the process proceeds to s3 without performing any special processing in s2. At this time, the time required for the processing of s1 and s2 is a very short time (small time). Thereafter, when the main switch is turned on, the general mode program 22 is read (s4), and the general mode program is executed (s5).

As described above, the television 1 of this embodiment executes the adjustment mode switching program 24 only once when power is supplied to the apparatus main body for the first time, and stores the program in the EEPROM 3a at this time. The existing adjustment mode switching program 24 is deleted.

On the other hand, in a general television 1 production line, when the assembly of the television 1 main body is completed and each unit is adjusted, power is supplied to the television 1 for the first time to operate. Therefore, when adjusting each part of the television 1 at the factory, the adjustment mode switching program 24 is executed. Therefore, a worker who adjusts each part of the television 1 simply connects the AC plug 9b of the television 1 for adjusting each part to an outlet, and the television 1 turns on the main switch and executes the adjustment mode program 23. I do. Further, since the adjustment mode switching program 24 is programmed so as to delete the adjustment mode switching program 24 stored in the EEPROM 3a, there is no need to delete the adjustment mode switching program 24. Therefore, the labor required for the adjustment work of the operator can be reduced and the cost of the main body can be reduced.

When the adjustment work of each part by the operator is completed, the adjustment mode switching program 24 stored in the EEPROM 3a is erased, so that the adjustment mode switching program 24 is not executed after the shipment. . That is, when the user connects the AC plug 9b of the main body to the outlet, the adjustment mode switching program 24 is not executed, so that the operability of the user is not reduced.

As shown in FIG. 5, an adjustment process (s 21) for adjusting the television 1 may be incorporated between s 13 and s 14 of the adjustment mode switching program 24 described in the above embodiment. However, the adjustment process executed in s21 is an adjustment that allows the television 1 to determine the appropriateness value. Adjustments that require visual confirmation by the operator will be performed by the operator as before.

As described above, by incorporating the adjustment process for adjusting the television 1 into the adjustment mode switching program 24, the total number of adjustment items to be adjusted by the operator can be reduced. Therefore, the labor of the operator can be further reduced, and the cost of the apparatus main body can be further reduced.

Further, as shown in FIG. 6, whether or not a predetermined code is input between s13 and s14 of the adjustment mode switching program 24 described in the above embodiment (a predetermined input operation to the apparatus main body). (Step S25) for determining whether or not the adjustment mode switching program 24 stored in the EEPROM 3a may be deleted in step s14 when a predetermined input operation is performed.

At a factory, the AC plug 9b of the television 1 may be connected to an outlet before adjusting the components of the television 1 for some reason. However, when the purpose of connecting the AC cord of the television 1 is not the adjustment of each part, the adjustment work is not performed naturally. At this point, if the adjustment mode switching program 24 is erased from the EEPROM 3a, the adjustment mode switching program 24 is not executed when actually adjusting the components of the television 1.

However, by providing the process of s25, even if the AC plug 9b is connected to the outlet for some reason before the adjustment, the predetermined input operation is not performed, so that the adjustment mode switching program 24 is not erased. Therefore, since the adjustment mode switching program 24 is executed at the time of adjustment of each section of the television 1, the above effects can be obtained.

The present invention can be applied not only to the television 1 described in the above embodiment, but also to other types of electronic devices such as a video, a televideo (an electronic device integrating a television and a video). Applicable.

[0055]

[Effect of the invention]

 As described above, according to the present invention, the labor required for the adjustment work can be reduced, and the cost of the main body can be reduced. In addition, a decrease in operability of the user can be prevented.
