Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control commander, and particularly to a remote control commander suitable for controlling audio equipment, visual equipment, and the like.

[Summary of the invention]

The present invention provides a remote control commander that includes means for generating a number of signals corresponding to the rotation angle of a roller, an up/down counter to which the signal is supplied as an input for either up or down, and a signal and a switching means provided between the up/down counter and the up/down counter to determine whether the counted value of the up/down counter is the initial value or not, and to transmit when the counted value is not the initial value. means for generating a command signal; and means for transmitting a remote control signal in response to the transmitted command signal, and each time the remote control signal is transmitted, the other input of up or down is input to an up/down counter. By providing a means for generating an up/down counter and a means for determining whether the count value of the up/down counter is equal to or greater than a predetermined value and turning off the switching means when the predetermined value is exceeded,
It can prevent the transmission of excessive remote control signals that exceed the necessary and sufficient values set by the up/down counter, and controllable range (for example, the number of windows on the west face, analog It is possible to prevent unnecessary transmission of remote control signals exceeding the number of steps for volume control, etc., and the transmission of unnecessary remote control signals that exceeds the number of steps for controlling the amount, etc.) can be prevented, and even if the rotation of the roller is stopped, it will continue for a long time. It is possible to prevent the external line signal from continuing to be transmitted for longer than necessary, and improve operability. The remote control signal corresponding to the transmission command signal can be sent without fail.
This prevents the remote control signal from not being sent due to overflow of the up/down counter, which was the case in the past.
Therefore, the movement of the roller and the control result corresponding to the movement of the roller can be matched, the operability can be improved, and the counting capacity of the up/down counter can be reduced.

[Conventional technology]

Remote controls are often used to control audio equipment, visual equipment, and other home appliances, and the input operation means for this remote control are as follows:
Commanders are often used.

As this commander, a button type commander is mainly used. In addition, other than button-type commanders, there are Japanese Patent Application Nos. 2-114364, 2-160369, and 2-1999 proposed by the applicant of the present invention.
There is a roller type commander as disclosed in Japanese Patent No. 200132.

In the case of the button-type commander mentioned above, the remote control signal is sent only when the switch button is pressed! , cursor movement, polyneme adjustment, and other analogue and graphical control can be achieved by releasing your finger from the switch button at the desired position while looking at the screen display.

In addition, in the case of the roller-type commander mentioned above, a remote control signal is sent in response to the rotational movement of the roller, so it is possible to move the cursor or control analog amounts in the same way as with button-type commanders. Become.

[Problem to be solved by the invention]

By the way, in the case of a roller-type commander, it takes a predetermined time, for example, 1 to send a remote control signal once.
It takes about 35 as and the mote control signal cannot be sent out about 8 times in 1 second.
Since there is no particular restriction on the rotation of the roller, if the rotation of the roller is accelerated, the sending of the remote control signal may not be able to correspond to the rotation of the roller.

For example, if the roller is rotated by more than twice the above-mentioned predetermined angle, while the remote control signal corresponding to the first rotation operation is being sent, the second and subsequent rotation operations
Although a transmission command signal requesting the transmission of a remote control signal is output in response to the rotational movement, the transmission command signal is invalidated because the transmission of the remote control signal cannot keep up with the transmission command signal described above. The remote control signal corresponding to the transmitted command signal was not transmitted.

Therefore, the number of remote control signals proportional to the amount of rotation of the roller may not be sent out, and in this case,
There has been a problem in that the movement of the cursor or the control of analog amounts no longer corresponds to the rotation of the roller, resulting in difficulty in operability.

Therefore, the patent application No. 2-2 proposed by the applicant of the claimed invention
In the specification of No. 00132, the number of times a transmission command signal is outputted is counted using a counter, and the number of remote control signals corresponding to the count value n is transmitted, and the count value n is decremented each time the transmission is completed. A technique for doing so has been disclosed.

However, in such conventional technology, on the other hand, if the rotation of the roller is increased more than necessary, the transmission command signal outputted more than necessary is counted by a counter and held as a count value n, so that the original , even unnecessary remote control signals are sent out continuously, which poses a problem in that it takes time to send the remote control signals, creating difficulties in operability.

In addition, in such conventional technology, on the other hand, there is a limit to the number that can be counted by the counter, and as in the above-mentioned case where the rotation of the roller is increased more than necessary, the transmission command exceeds the limit value. When the signal is output, there is a problem in that the transmission command signal that overflows beyond the limit value is invalidated.

In order to solve this problem, there has been a desire for a technology that can count a sufficient number of transmission command signals and transmit a corresponding remote control signal.

Further, in the conventional roller type commander, when the roller is moved alternately in both directions, the transmission request signal continues to be output in response to the operation, and there is a problem that the cursor does not stay at the intended position.

Therefore, an object of the present invention is to provide a remote control commander intended to improve operability.

[Means to solve the problem]

The present invention includes means for generating a number of signals corresponding to the rotation angle of the roller, an up/down counter to which the signal is supplied as an input for either up or down, means for generating the signal, and up/down counter. a switching means provided between the up/down counter and the up/down counter; and means for determining whether or not the counted value of the up/down counter is an initial value, and generating a transmission command signal when the counted value is not the initial value; means for transmitting a remote control signal in response to a transmission command signal and generating the other input of up or down to an up/down counter each time the remote control signal is transmitted; The configuration includes means for determining whether or not the count value of the counter is equal to or greater than a predetermined value, and turning off the switching means when the count value is equal to or greater than the predetermined value.

[Effect]

A signal is formed corresponding to the rotation angle of the roller, and this signal is supplied as an input to one of up-counting and down-counting of an up-down counter, and up-counting or down-counting is performed.

The count value of the up/down counter is output and the initial value is
For example, it is determined whether or not it is zero, and it is also determined whether or not it is a predetermined value.

This predetermined value is the number of remote control signals to be sent, and is set to a necessary and sufficient value.

When the count value is not the initial value and does not reach a predetermined value, a transmission command signal corresponding to the count value is output.

Further, when the count value is not the initial value but reaches a predetermined value, the predetermined count value is supplied to the up/down counter and preset, and a transmission command signal corresponding to this count value is output.

A remote control signal is sent in response to a transmission command signal, and each time a remote control signal is sent, a signal is formed and supplied as the input for the other of the up-count or down-count of an up/down counter. and an up-count or down-count is performed.

Then, until the count value reaches the initial value, for example, zero,
A remote control signal corresponding to the transmission command signal is sent.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 6. In this embodiment, the present invention is applied to a system that remotely controls a television device and controls other equipment via a microcomputer provided in the television device.

FIG. 1 shows the configuration of a commander for remote control, where l is a roller section and 2 is a switch provided in association with the roller section 1, for example a tact switch. As shown in FIGS. 2A and 2B, the roller portion 1 is rotatably supported by a case 10 by a shaft 11 made of a rod-shaped spring, and has a roller l whose circumferential surface protrudes from the upper surface of the case 10.
It has a.

Further, the case 10 is provided with a commander power switch indicated by 13. An infrared signal 5oot, which is a remote control signal modulated into infrared rays, is transmitted from the end surface 14 of the case 10. As shown in FIG. 2C, the commander may be provided with a display section 16 such as a liquid crystal display, and the roller 1a may be operated without looking at the display on the display section 16.

Note that 15 is the other end surface of the case 10.

The roller 1a has a function as a pointing device for selecting a menu or control element displayed on the screen, as will be described later, and a function as an input device for a control amount.

When the roller 1a is pushed down, the switch 2 is turned on via the auxiliary plate 12, a pulse SC corresponding to the on/off of the switch 2 is generated, and this pulse SC is supplied to the detection circuit 4.

Further, although not shown, a rotation detector that generates a detection pulse signal in accordance with the rotation of the roller 1a is provided on the roller portion l. More specifically, the detection pulses SA and SB are generated by a rotary switch, a magnetic detector consisting of a magnet and a Hall element, or an optical detector consisting of a light emitting element, a light receiving element and a rotating slit plate. .

FIG. 3 shows two-phase detection pulses SA and SB generated according to a predetermined amount of rotation of a-la, that is, the rotation angle.
The phase relationship between the detection pulses SA and SB indicates the rotation direction of the roller 1a, and the number of generated pulses indicates the amount of rotation of the roller la.

The number of detection pulses SA and SB is a predetermined number per rotation of the roller 1a, and the frequency thereof is proportional to the rotation speed.

As shown in FIG. 3, the phase relationship in which the rising edge of the detection pulse S^ occurs before the rising edge of the detection pulse SB means that the roller 1a is rotated in the direction of arrow C in FIG. are doing. Rotation of the roller la in the direction of arrow A corresponds to moving the cursor upward on the tube surface.

On the other hand, the rising edge of the detection pulse SB is the same as that of the detection pulse SA.
The phase relationship that occurs before the rise of roller 1a
This means that it has been rotated in the direction of arrow C in FIG. Rotation of the roller la in the direction of arrow B corresponds to moving the cursor downward on the tube surface. Furthermore, the amount of rotation of the roller la is detected by counting the number of one detection pulse, for example SA. The above detection pulse SA
, SB are supplied to the detection circuit 3.

The detection circuit 3 detects the rotation direction based on a comparison of the rising edges of the detection pulses SA and SB, and generates a positive pulse signal P1 or P2 at each detection timing.

The detection circuit 4 generates a positive pulse signal P3 indicating that the roller 1a is pushed in the direction of arrow C in FIG. 2 from the pulse SC corresponding to the on/off of the switch 2.

The pulse signal PI moves the cursor upward or changes the analog amount in the increasing direction, so to speak, indicating a change in the upward direction. Further, the pulse signal P2 moves the cursor downward or changes the analog amount in the decreasing direction, so to speak, indicating a change in the downward direction. The pulse signal P3 indicates that the roller 1a is pushed in. The zero rotation amount is expressed by the number of pulse signals PI or P2.

By pressing the aforementioned power switch 13, the commander is put into a standby state.

When the push-in operation, that is, the click operation, of the roller 1a is performed in the standby state, the remote control signal can be sent. Note that instead of this click operation, the remote control signal may be transmitted by a double click operation in which the roller la is pressed twice in a very short period of time.

Pulse signals P1 and P2 are formed in the detection circuit 3 by the rotation operation of the roller 1a, and pulse signals P3 are formed in the detection circuit 4 by the pushing operation of the roller 1a.

Pulse signal PI is supplied to circuit block 5.

By supplying this pulse signal P1 to the circuit block 5 described above, a transmission command signal S1 for moving the cursor upward or changing the analog amount in an increasing direction is generated.
is, for example, set to a high level.

Further, the pulse signal P2 is supplied to the circuit block 6.

By supplying this pulse signal P2 to the circuit block 6 described above, a transmission command signal S2 is generated for moving the cursor downward or changing the analog amount in a decreasing direction.
is, for example, set to a high level. Note that the configuration and operation of the circuit block 6 described above are the same as those of the circuit block 5, so in the following explanation, only the circuit block 5 will be explained and redundant explanation will be omitted.

As shown in FIG. 1, the circuit block 5 mainly includes a switch circuit 61, an up/down counter 62, comparators 63, 64, a flip-flop 65, an inverter 66, and the like.

The pulse signal P1 supplied from the above-described detection circuit 3 is supplied to an up-count terminal of an up/down counter 62 via a switch circuit 61.

In the up/down counter 62, the above-mentioned pulse signal P
1 is counted in the upward direction. This count value n is then supplied from the output terminal to comparators 63 and 64.

In the comparator 64, the supplied count value n is compared with an initial value, for example, "0", and when the count value n is other than 10", a high-level transmission command signal S1 is formed, and this high-level transmission command signal S1 is generated. A level transmission command signal S1 is supplied to a remote control code encoder (hereinafter simply referred to as an encoder) 9.

When the encoder 9 detects the high-level transmission command signal Sl, it supplies the transmission circuit 17 with a remote control signal in a predetermined format corresponding to the transmission command signal.

The transmitting circuit 17 is provided with a light emitting diode and its driving amplifier, and the above-mentioned remote control signal is converted into an infrared signal and sent to the television device. Then, in the transmitting circuit 17, each time a remote control signal is sent, a transmission end signal SBI, St! 2
is formed, and this transmission end signal SEI is supplied to the down count terminal of the up/down counter 62.

The up/down counter 62 receives the transmission end signal SEI.
Each time the count value n is received, the count value n is counted down. In this up/down counter 7, the above-mentioned up counting and down counting are performed in parallel, and when the comparator 8 determines that the count value n is (n-1) after down counting, A transmission command signal S1 is then supplied to the encoder 9, and a remote control signal is sent out from the transmission circuit 17 as described above.

The comparator 63 is for checking the count value n of the up/down counter 62. This comparator 63 uses the above-mentioned count value n and a preset maximum value MAX (
In the illustrated example, a comparison is made with the maximum value MAX-16). When the count value n reaches the maximum value MAX, a high-level maximum value attainment signal SMAX is supplied to the load terminal of the up/down counter 62 and the set terminal of the flip-flop 6-5.

In this embodiment, the maximum value WAX mentioned above is set as the number of remote control signals to be sent.
For example, the number of windows on the screen and the number of analog control steps for volume, picture, etc. can also be set.

In the flip-flop 65, since the output signal is set, the inverted output signal [in this specification, the symbol for negative logic is denoted by "*"
The QQ umbrella becomes low level, and this low level inverted output signal QOI is supplied to the switch circuit 61.

The switch circuit 61 is turned off by the above-mentioned low level inverted output signal QO$.

By turning off the switch circuit 61, the supply of the pulse signal P1 to the up/down counter 62 is cut off, and up-counting in the up/down counter 62 is stopped.

Further, in the up/down counter 62, when the above-mentioned maximum value attainment signal S MAX is supplied to the load terminal, a predetermined value, for example 3, supplied via the terminal 67 is fetched from the preset terminal and preset. Ru. As a result, a new count value n in the up/down counter 62
A predetermined value of "3" is supplied to the capacitor 64 as a predetermined value.

In other words, when the count value n reaches the maximum value MAX (-16), the count value n is forcibly preset to 3''. Value MAX (= 16)
This is to prevent the time required for sending out from becoming too long if it is sent out twice.

After that, comparator 64, encoder 9, transmitter circuit 1
In route 7, the same operation as described above is performed, and a predetermined number of times (-3) of remote control signals are converted into infrared signals and sent out, and each time a remote control signal is sent out, an infrared signal is formed. Transmission end signal SE
The count value n (n=3) is down-counted by I and SE2.

When the sending of the remote control signal based on the above-mentioned transmission command signal S1 and the down-counting based on the transmission end signal SEI are repeated a predetermined number of times (n=3), the count value n (n=0) is reached.

When the count value n becomes (n=o), the comparator 64
When the transmission command signal Sl supplied to the encoder 9 is set to low level and the encoder 9 detects the transmission command signal S1 as low level, the remote control signal is supplied to the transmission circuit 17 and the transmission circuit 17 is turned off. The transmission of infrared signals is stopped.

At this time, a signal 310 formed by transmitting the transmission command signal S1 through the inverter 66 is supplied to the reset terminal of the flip-flop 65 and the reset terminal of the amplifier/down counter 71 of the circuit block 6. This signal 31
0 is set to high level by the inverter 66, the flip-flop 65 is reset, the inverted output signal Qo becomes high level, and the switch circuit 61 is turned on. This allows the pulse signal P1 from the detection circuit 3 to be supplied to the up-count terminal of the up-down counter 62.

Further, the above-mentioned signal 31G is supplied to the reset terminal of the up/down counter 71 of the circuit block 6, and a signal S is generated by the transmission command signal S2 output from the comparator 72 of the circuit block 6 passing through the inverter 73.
20 is an up/down counter 62 of the circuit block 5
It is designed to be supplied to the reset terminal of.

2, the signal 320 from the other circuit block 6 is supplied to the reset terminal of the up/down counter 62 of the circuit block 5, and the signal 320 from the other circuit block 5 is supplied to the reset terminal of the up/down counter 71 of the circuit block 6. The reason why the signal 510 is supplied is that when the roller 1a is rotated alternately in the rotational directions A and H, the transmission command signals S1 and S2 are outputted correctly and displayed on the screen. This is to ensure that the cursor 47 is moved correctly.

For example, when the roller 1a is being rotated in the direction of arrow A, if an operation is repeated in which it is rotated in the direction of arrow A, then rotated in the direction of arrow B, and then rotated again in the direction of arrow A, , a pulse signal P2 corresponding to rotation in the direction of arrow B.
is supplied to the circuit block 6 and counted by an up/down counter 71 within the circuit block 6. Then,
After the upward movement of the cursor 47 is completed, the remote control is output in response to the count value n held in the up/down counter 71 of the circuit block 6, without having to rotate the roller 1a again. The cursor 47 will move downward based on the signal. This makes the cursor 47 appear to be moving up and down and back on the screen, making it unsightly.

Therefore, when all transmission of the infrared signals 5out is completed and the count value n reaches (n=o) and the comparator 64 to 9 transmission command signal S1 is set to low level, a high level signal 310 is sent to the circuit block 6.・By being supplied to the reset terminal of the down counter 71, the up
The count value n held in the down counter 71 is reset.

As a result, for example, when the count value n of the up/down counter 62 of the circuit block 5 becomes (n=0), the up/down counter 7 of the other circuit block 6
The count value n of 1 is also reset to (n=0), and the cursor 47 can be moved accurately. In the above description, the reset of the count value n held in the circuit block 6 while the circuit block 5 is in operation is explained. The same applies to resetting the count value n.

In the description of this embodiment, a series of operations are explained when a high-level transmission signal S1 is supplied from the circuit block 5, but when the transmission command signals S1 and S2 are supplied from both circuit blocks 5 and 6. In such a case, for example, when a high level transmission command signal S2 is supplied from the circuit block 6 during the processing period for the transmission command signal S1 supplied at a high level from the circuit block 5, the transmission After the processing for the command signal S1 is completed, the transmission command signal S2 supplied from the circuit block 6 is processed. When the transmission command signal S2 is accepted and processed, a remote control signal in a predetermined format corresponding to the transmission command signal S2 is supplied to the transmission circuit 17.

According to this embodiment, when the count value n of the up/down counter 62 is not the initial value "0" and does not reach the maximum value MAX, the transmission command signal S1 corresponding to the count value n
is output, and when the count value n is not the initial value "0" but reaches the maximum value A^X, the predetermined count value n (
n=3) is supplied to the up/down counter 62 and set, and the transmission command signal S corresponding to this count value n is
1 is output, and the remote control signal corresponding to the transmission command signal S1 is sent until the count value n reaches the initial value "0". It can prevent the transmission of excessive remote control signals that exceed the maximum value MAX, and prevent unnecessary remote control signals that exceed the controllable range (e.g., the number of windows on the screen, the number of steps for controlling analog quantities, etc.) transmission can be prevented.

Therefore, since the transmission of excessive remote control signals exceeding the maximum value MAX set by the up/down counter 62 is prohibited, even if the rotation of the roller 1a is stopped, the transmission of excessive remote control signals is prohibited. It is possible to prevent the transmission state of the infrared signal 5out from continuing as described above,
Operability can be improved.

In addition, since the up/down counter 62 is set to a maximum value MAX that is necessary and sufficient, the counted transmissions can be performed within the range of not exceeding the maximum value MAX set by the up/down counter 62. A remote control signal corresponding to the command signal S1 can be transmitted without fail.

Therefore, it is possible to match the control results corresponding to the movements of the roller la and the movement of the roller 1a, and there is an effect that the operability can be improved.

Furthermore, the counting capacity of the up/down counter 62 can be reduced.

Further, according to one embodiment, since the signal 310.320 from the other circuit block 5.6 is supplied to the reset terminal of the up/down counter 62.71 of the circuit block 5.6, the roller 1a is 8 Even if the cursor 47 is moved alternately in both directions, the count value n of the other circuit block 5.6 can be reset when the operation of each circuit block 5.6 is completed, and the cursor 47 will not stop at the intended location on the screen. can be prevented.

The irradiation direction of the light emitting section 30a can be adjusted to any direction. 52 is a speaker.

In the embodiment described above, when the roller 1a is pushed in while the television device is powered on, a menu screen is displayed on the screen 45. In this case, the menu screen may be displayed by pressing the roller 1a twice in a very short period of time, or by double-clicking.

The menu screen is used to specify switching of the video input of the television device, to select the television device or an external device as the device to be controlled, and to select the content of control of the television system.

As the control contents of the television device, daily control contents such as channel switching and volume adjustment, and adjustment contents such as screen brightness are set.

The control contents used on a daily basis may be displayed by pushing the roller 1a before the adjustment contents.

Next, the adjustment of the television silon device will be explained.

When the cursor 47 is moved with the roller 1a to select the adjustment content menu and the roller 1a is pushed in, the display screen 45A shown in FIG. 6A appears on the tube surface 45.0 display screen 45A
Here, display blocks 53a to 53g each consisting of a control content display and a control amount display are displayed vertically.

In the illustrated example, the display block 53a has a hue control (with a control amount range of -31 to +32), and the display block 53b has a color control (with a control amount range of θ to 6).
3) The display block 53c has a brightness control (the control amount range is θ to 63), the display block 53d has a picture (brightness level) control (the control amount range is 0 to 63), and the display block 53e has a sharpness control.

is provided with a display block for resetting each control amount to its initial value, and a display block 53g is provided with a display block for returning to the previous page.

As an example, when performing the due control, the roller 1a is used to move, for example, a red cursor 47 to the position of the due control display block 53a. The background color of the other display blocks 53b to 53g is white. Then, when the switch 2 is turned on by pushing the roller 1a, the function of the hue control can be selected. At this time, as shown in FIG. 6B, the cursor 47 blinks and a mark 48 appears on the screen indicating that the function of the roller 1a has changed from the pointing device function to the control amount input function.

The blinking of the cursor 47 and the mark 48 cause the roller 1 to
It is obvious at a glance that the function of a has changed. Of course, changes in the function of the roller la may be displayed using shapes, colors, marks, etc. other than those shown.

When the roller 1a is rotated upward in the direction of arrow A in FIG. 2 without looking at the display screen 45B in FIG. 6B, the controlled object 2
A control signal in the direction of increasing the numerical value is supplied to the control terminal of the hue control circuit in 9, and the numerical value on the display screen 45B also increases in accordance with the signal. When the roller 1a is rotated downward, in the direction of arrow B in FIG.
The value on 5B also decreases. Adjustments other than hue control can be made in the same way by only operating the roller 1a.

By rotating the roller 1a in the display block 53a, the cursor 47 indicated by diagonal lines is moved to the display block 53a.
When attempting to move the tube surface 45 downward from the display block 53g, the CPU 23 uses the decoder 2 described above.
Based on the code signal from 2, the cursor 47 displayed on the display screen 45 is controlled to move downward.

Then, by selecting the display block 53g on the previous page with the roller 1a and pushing the roller 1a, as shown in FIG.

can be displayed on the tube surface 45.

On the display screen 45C, display blocks 54a to 54g corresponding to VTR operations such as playback, recording, fast forward, etc. are arranged vertically, and when the desired display block is selected by rotating the roller 1a and the roller 1a is pushed in, , a remote control signal corresponding to the selected operation is transmitted from the transmitting circuit 30 to V.
Given for TR. Further, the VTR sends a return signal indicating the operating state to the television apparatus as an infrared signal. With this return, the operating status of the external VTR can be displayed on the display screen 45C.

In this case, if the configuration is such that no return is made, the cursor changes color or blinks on the display screen 45C only while the remote control signal is being sent from the transmitting circuit 30, and after the remote control signal is sent, , the original display is returned.

In the above embodiment, an example in which the cursor is moved in the vertical direction has been described, but the cursor is not limited to this, and the cursor may be moved in the left and right directions according to the movement of the roller. Display blocks to be controlled are arranged horizontally on the screen. Of course, the cursor may be moved diagonally. Further, even in the case where the commander does not have a CRT display, the same control as in the above embodiment can be performed by providing the commander with the display section 16 as in the example shown in FIG. 2C.

In the embodiment described above, the cursor 47 is displayed by changing the color of the display block, but the present invention is not limited to this, and for example, the cursor 47 may be displayed as an arrow.

Next, regarding other embodiments of the present invention, FIGS.
This will be explained with reference to FIG.

In the technique shown in the above embodiment, while the infrared signal 5out shown in FIG.
It is effective if the number of pulse signals P1 shown in FIG. A corresponding to the maximum value MAX (for example, MAX=11) is supplied and counted. The maximum value MAX (=
11) is detected, count-up is prohibited, and a predetermined value (n=3) is set as shown in FIG. 8B. After this predetermined value (n=3) is set, as shown in FIG. 8C, the operation of the commander in which the infrared signals 5out are outputted the preset number of times (n-3) is completed.

However, the infrared signal 5out shown in FIG.
If the pulse signal P1 shown in FIG. 9A continues to be output only 2 or 3 times while the pulse signal P1 is sent out once, the up/down counter will continue to count down as shown in FIG. 9B. The count value n of 62 gradually increases.

Even if the rotation of the roller 1a is stopped after the pulse signal Plb shown in FIG. 9A is supplied, the count value n at this stage is maintained at (n=8), so
After the timing at which the pulse signal Plb is supplied, the infrared signal 5out is transmitted eight times in succession.

Therefore, in addition to the configuration of the above-described embodiment, this other embodiment includes an OR gate 82, a timer circuit 81, and a trigger pulse PTR for starting the timer circuit 81 on the input terminal side of the flip-flop 65. By providing the AND gate 82 which is formed based on the pulse signal P1 and the signal SIO, the amplifier can be counted only during the predetermined time when the timer circuit 81 is activated, and after the predetermined time is over, the infrared ray Up-counting is prohibited until the transmission of signal 5out is completed. In the following description, parts common to those in the above embodiment are given the same reference numerals, and redundant description will be omitted.

The transmission command signal S1 output from the comparator 64 is
The signal is supplied to the AND gate 82, the reset terminal of the timer circuit 81, the reset terminal of the flip-flop 65, the reset terminal of the up/down counter 71 of the circuit block 6, etc. via the encoder 9 and the inverter 66.

When the transmission of the infrared signal 5out from the transmission circuit 17 is completed and the count value n is set to (n-0), the transmission command signal S
1 is a low level. As a result, the signal 5 generated by the transmission command signal S1 passing through the inverter 66
10 is set to high level, and this signal 310 is supplied to the reset terminal of the flip-flop 65.

Since the output signal of the flip-flop 65 is reset, the inverted output signal QO becomes high level, and the switch circuit 61 is turned on. This makes it possible to supply the pulse signal P1 from the detection port g3 to the up-count terminal of the up-down counter 62.

During the period when the signal S10 is at high level, the pulse signal P
1 is supplied to the AND gate 82, this pulse signal P1 is passed through the AND gate 82 to the timer times! ! ff+8
The trigger pulse PTR is supplied to the trigger input terminal of No. 1 as a trigger pulse PTR.

The timer circuit 81 inputs a trigger pulse PT to a trigger input terminal.
It is activated when R is supplied, and after a predetermined time T has elapsed, the flip-flop 6 is connected from the output terminal via the OR gate 83.
A pulse Pa is supplied to the set terminal No. 5. The above-mentioned predetermined time T is a period of time that does not make the user feel uncomfortable even if the infrared signal 5out is sent after the rotation of the roller 1a is stopped, for example, a period of time that the user does not feel uncomfortable even if the infrared signal 5out is sent three times in succession. It is considered as time.

In the flip-flop 65, the output signal is set by supplying the above-mentioned pulse Pa to the set terminal, so the inverted output signal QO rate becomes low level, and the switch circuit 61 is turned off.

By turning off the switch circuit 61, the supply of the pulse signal P1 to the up/down counter 62 is cut off, and up-counting in the up/down counter 62 is stopped.

The comparator 63 has exactly the same configuration and function as the above-mentioned embodiment, and the difference is that the maximum value MAX (in the illustrated example, the maximum value MAX = 10) and the maximum value output from the comparator 63 Value arrival signal S MAX
is supplied to the set terminal of the flip-flop 65 via the OR gate 83.

Hereinafter, the circuit operation of this other embodiment will be explained with reference to the timing chart shown in FIG. 1O.

The first relationship is between the count value n of the up/down counter 62 as the roller 1a rotates and the transmission of the infrared signal 5out.
The cases are classified into the third case and shown in FIG. In the following description of the first to third cases, it is assumed that the transmission command signal S1 is at a low level as an initial condition.

10A shows the pulse signal P1 supplied to the up/down counter 62, and FIG. 10B shows the count value n of the up/down counter 62. FIG. 10C shows a state in which the transmission command signal S1 is output, and FIG. 10 shows a state in which the remote control signal is converted into an infrared signal 5out and sent out.

Further, FIG. 10E shows the transmission end signal SEI, FIG. 10F shows the maximum value reaching signal S MAX, and the first
0G shows the pulse Pa of the timer circuit 81, and the first
FIG. 0H shows the signal input to the set terminal of the flip-flop 65.

Further, FIG. 10I shows a signal 310 formed by inverting the transmission end signal SEI at the inverter 66, and FIG. 10J shows the inverted output signal QO of the flip-flop 65.
*It is shown.

The circuit operation will be explained for each case below.

(1) Case 1 In this case 1, the rotation of the roller la is relatively slow, the interval at which the pulse signal P1 is supplied is longer than the time required to send out the infrared signal 5out, and the pulse Pa from the timer circuit 81 is also This is an example in which the maximum value reaching signal SM^X from the comparator 63 is also not output.

At the initial stage of case 1, the transmission command signal S1 is at a low level, so the signal S10 is at a high level. Therefore, the flip-flop 65 is reset, the switch circuit 61 is turned on, and the pulse signal P1 from the detection circuit 3 can be supplied to the up-count terminal of the up-down counter 62.

Pulse signals Pla, Pib, Pl shown in FIG. 10A
Every time c is input, the up/down counter 62
The pulse signal P1 is counted. Thereafter, the same operation as in the above embodiment is performed in the path of the comparator 64, encoder 9, and transmission circuit 17, and the remote control signal corresponding to the transmission command signal S1 formed based on the count value n is transmitted. It is converted into an infrared signal 5out and sent out, and the count value n is counted down by the transmission end signals SE1 and SF3.

When the count value n reaches (n=0), the comparator 64
The transmission command signal S1 supplied from the encoder 9 to the encoder 9 is set to low level, and at the stage when the encoder 9 detects the transmission command signal S1 as low level, the supply of the remote control signal is stopped.

Incidentally, since the above-mentioned high level signal SIO is also supplied to the AND gate 82, the AND gate 82 outputs a trigger pulse PTR to the timer circuit 81 at the timing when the pulse signal P1 is supplied.

However, as shown in the 10th DC, I, when the transmission of the infrared signal 5out is completed and the transmission command signal S1 becomes low level, the signal s10 becomes high level. Since this high level signal 310 is supplied to the reset terminal of the timer circuit 81, the timer circuit 81 is reset each time. As a result, the timer circuit 81 outputs the pulse Pa
is never output.

(2) Case 2 This case 2 is a case in which the rotation of the roller Ia is faster than in case 1, the interval at which the pulse signal PI is supplied is long, slightly shorter than the time required to transmit the infrared signal 5out, and the timer circuit This is an example in which the pulse Pa from 81 is output.

At the initial stage of case 2, the transmission command signal S1 is at a low level, so the signal 310 is at a high level. Therefore, the flip-flop 65 is reset, the switch circuit 61 is turned on, and the pulse signal P1 from the detection circuit 3 can be supplied to the up-count terminal of the up-down counter 62.

At the timing when the first pulse signal Pld is supplied, a trigger pulse PTR is outputted from the AND gate 82 to the timer circuit 81 in response to the pulse signal Pld.

In the timer circuit 81, as shown in FIG.
After the lapse of time, the pulse Pa is supplied to the set terminal of the flip-flop 65 via the OR gate 83.

Since the output signal of the flip-flop 65 is set by the pulse Pa, the switch circuit 61 is turned off. As a result, the supply of the pulse signal P1 supplied after the predetermined time T, specifically PIe, to the up/down counter 62 is cut off, and up-counting is stopped.

The count value n of the pulse signal Pl after being supplied and down-counted within a predetermined time T is determined by the up/down counter 6.
2 is held as (n=4), and thereafter, the same operation as in the above-mentioned embodiment is performed in the path of the comparator 64, encoder 9, and transmission circuit 17, and the count value is formed based on the count value n. The remote control signal corresponding to the transmission command signal S1 is converted into an infrared signal 5out and sent out, and the count value n is counted down by the transmission end signals Sε1 and Sε2.

When the count value n becomes (n=o), the comparator 64
The transmission command signal Sl supplied from the encoder 9 to the encoder 9 is set to low level, and at the stage when the encoder 9 detects the transmission command signal Sl as low level, the supply of the remote control signal is stopped.

At this time, the signal SIO is at high level, so
The flip-flop 65 is reset and the switch circuit 6
1 is turned on again.

This allows the pulse signal P1 from the detection circuit 3 to be supplied to the up-count terminal of the up-down counter 62.

(3) Case 3 In this case 3, the rotation of the roller 1a is even faster than in case 2, and the interval at which the pulse signal P1 is supplied is much shorter than the time required to transmit the infrared signal, and the comparator 63 This is an example in which the maximum value reaching signal S MAX is output from.

At the initial stage of case 3, the transmission command signal Sl is at a low level, so the signal 510 is at a high level. Therefore, the flip-flop 65 is reset and the switch circuit 6e is turned on, so that the pulse signal Pl from the detection circuit 3 can be supplied to the up-count terminal of the up-down counter 62.

Up/down counter 62 in response to pulse signal PI
Then, the pulse signal Pl is counted. Thereafter, the same operation as described above is performed in the path of the comparator 64, encoder 9, and transmission circuit 17, and the remote control signal corresponding to the transmission command signal Sl formed based on the count value n becomes the infrared signal 5out. At the same time, the count value n is counted down by the transmission end signals SEI and Sε2.

Then, the comparator 63 compares the above-mentioned count value n with a preset maximum value MAX (maximum value MAχ=IO in the illustrated example).

As shown in FIG. 10A, the count value n of the pulse signal P1 reaches the maximum value MA at the timing when the pulse signal Plf is supplied, so the high level maximum value attainment signal S MAX rises and falls at this timing. It is supplied to the load terminal of the counter 62 and the set terminal of the flip-flop 65 via the OR gate 83.

In the flip-flop 65, the output signal is set by the maximum value reaching signal SMAX, so the switch circuit 61
is turned off. As a result, after the pulse signal Plf, the supply of the pulse signal P1 to the up/down counter 62 is cut off, and up-counting is stopped.

Further, in the up/down counter 62, when the above-mentioned maximum value attainment signal S MAX is supplied to the load terminal, the predetermined value "3" supplied via the terminal 67 is taken in from the preset terminal, and the up/down counter As the new count value n in the counter 62, °°3'' is supplied to the comparator 64.

After that, comparator 8, encoder 9, transmitter circuit 17
In the path, the same operation as in the above-mentioned embodiment is performed, and the remote control signal formed based on the predetermined value n is converted into an infrared signal 5out and sent out. , the count value n (n=3) is counted down.

When the count value n reaches (n=0), the comparator 64
The transmission command signal S1 supplied from the encoder 9 to the encoder 9 is set to low level, and at the stage when the encoder 9 detects the transmission command signal S1 as low level, the supply of the remote control signal is stopped.

At this time, the signal S10 is at a high level, so
The flip-flop 65 is reset and the switch circuit 6
1 is turned on again.

This allows the pulse signal P1 from the detection circuit 3 to be supplied to the up-count terminal of the up-down counter 7.

〔Effect of the invention〕

The remote control commander according to this invention includes:
When the count value of the up/down counter is not the initial value and does not reach the predetermined value, a transmission command signal corresponding to the count value is output, and when the count value is not the initial value and reaches the predetermined value, the The count value of is supplied to the up/down counter and preset, a transmission command signal corresponding to this count value is output, and the remote control corresponding to the transmission command signal is output until the count value reaches the initial value, for example, zero. Since the control signal is sent, it is possible to prevent the transmission of excessive remote control signals that exceed the necessary and sufficient value set by the up/down counter, and to control the controllable range [e.g. This has the effect of preventing unnecessary transmission of remote control signals exceeding the number of windows, the number of analog control steps, etc.).

Therefore, since the transmission of excessive remote control signals that exceed the necessary and sufficient predetermined value set in the up/down counter is prohibited, even though the roller rotation has been stopped, This has the effect that it is possible to prevent the infrared signal from continuing to be transmitted for an unnecessarily long period of time, and to improve operability.

In addition, since the up/down counter is set to a predetermined value that is necessary and sufficient, it corresponds to the transmission command signal counted within the range that does not exceed the predetermined value set by the up/down counter. The remote control signal can always be sent, and there is an effect that it is possible to prevent the remote control signal from not being sent due to overflow of the up/down counter as in the conventional case.

Therefore, the movement of the roller and the control result corresponding to the movement of the roller can be made uniform, and there is an effect that the operability can be improved.

Furthermore, there is an effect that the counting capacity of the up/down counter can be reduced.

Furthermore, according to the embodiment, since the reset terminal of the up/down counter of each circuit block is supplied with a signal via an inverter output from the comparator of the other circuit block, the roller can be moved alternately in both directions. When the operation of each circuit block is completed, the count value n of the other circuit block can be reset, which has the effect of preventing the cursor from stopping at the intended position on the screen.
