Description

  The present invention relates to a position input device for performing a position input operation, a remote control device including the position input device, and a remote operation system having the remote control device.

Conventionally, remote control devices (so-called remote control devices) have been used in many home appliances (see, for example, Patent Document 1). Many of the conventional remote control devices have a large number of keys corresponding to the functions of the device to be operated.
JP 05-056484 A (FIG. 2)

  In recent years, household appliances such as DVD recorders have become more multifunctional, and along with this, the number of keys and the like mounted on a remote control device for operating these appliances has increased remarkably. The operation is extremely complicated. For this reason, for the purpose of simplifying the operation of the multifunctional product, for example, an attempt to use a hierarchical menu has been made. However, an operation for selecting a menu by a key of the remote control device itself is not suitable for the user. There was a problem that the burden was large. For this reason, it has been required to easily operate various multifunctional devices.

  The present invention has been made in view of the above-described circumstances, and an object thereof is to enable easy operation of a device having a plurality of functions.

In order to solve the above-described problems, the present invention supports a sensing unit having a detection surface, an openable / closable lid covering the detection surface of the sense unit, and movable along the detection surface with the lid closed. And an operating element attached to the lid so as to move together with the lid when the lid is opened and closed, and position detecting means for detecting a position of the operating element with respect to the detection surface. The means detects an operation position when an operation is performed on the detection surface by an external position indicator with the lid open.
According to this configuration, when the operation is performed with the operator with the lid closed, the position of the operator is detected, and when the operation with the external position indicator is performed with the lid opened. The operation position is detected. For this reason, by opening and closing the lid, it is possible to switch between an operation by an operator attached to the lid and an operation by an external position indicator. As a result, the user can select an operation method desired by the user or can perform an operation by selecting a method suitable for a desired operation. Therefore, the operability of the position input device for performing the position input operation can be remarkably improved. Furthermore, when this position input device is used as an operation device in various devices such as electronic devices and computers, position input operations on these various devices can be easily performed, and even devices having complicated functions can be used. Since it can be operated easily, the operability can be greatly improved.

In the present invention, a hole may be formed in the lid, and the operation element may be exposed inside the hole. In this case, the user only needs to perform an operation of moving the operating element inside the hole, and an intuitive operation is possible.
In the present invention, the operation element may be configured by a flat plate portion having a plane substantially parallel to the detection surface and an operation projection portion standing on the flat plate portion and protruding from the hole. . In this case, the position input operation can be performed more easily by moving the operation protrusion.

  Further, in the present invention, the position detection means detects an operation position by the position indicator and a position of the operation element as an absolute position with respect to a detection area set in advance on the detection surface, and the lid is opened. Different detection areas may be set for the detection surface between the closed state and the closed state. In this case, even if the range in which the operator can be moved with the lid closed and the range that can be operated by an external position indicator with the lid open do not match, the lid can be opened and closed. Since the detection area to be set is set, position detection corresponding to the user's operation can be performed accurately.

In this invention, it is good also as a structure which provided the support mechanism which supports the said operation element so that a slide is possible in the direction orthogonal to the said predetermined direction and the said predetermined direction along the said detection surface. In this case, the position input operation can be easily performed only by performing an operation of moving the operation element supported by the support mechanism to an arbitrary position.
In the present invention, the position detecting means may stop the operation for detecting the position for a predetermined time when an operation of opening the lid and an operation of closing the lid are performed. In this case, since the position of the operation element is not detected when the operation element moves together with the operation of opening and closing the cover, there is an advantage that the position detection not intended by the user is not performed and a sense of incongruity does not occur. .

Furthermore, in the present invention, a coil is provided in each of the sense unit and the operation element, and the position detection unit is based on electromagnetic coupling generated between the coils of each of the sense unit and the operation element. Thus, the position of the operation element may be detected. According to this configuration, it is possible to reliably and promptly detect the position of the operation element with respect to the detection surface of the sense unit and the operation position by the position indicator.
In the present invention, the coil of the sense unit may be a plurality of loop coils forming a ring along the detection surface of the sense unit. In this case, it is easy to make the detection surface of the sensing portion thinner, and the position of the operation element can be detected reliably and accurately.

  In the present invention, the position detection unit may detect the position of the operation element with respect to the detection surface based on an electrostatic coupling state between the sense unit and the operation element. Alternatively, the position detection unit may detect the position of the operation element relative to the detection surface by detecting a pressing force applied to the detection surface from the operation element.

  In order to achieve the above object, the present invention provides a wireless transmission that wirelessly transmits the position input device and a signal indicating the position of the operation element detected by the position input device or the operation position of the position indicator. And a remote control device.

  In order to achieve the above object, the present invention provides the remote control device, display means for displaying an image on a display screen, and reception means for receiving a signal transmitted by a wireless transmission means included in the remote control device; There is provided a remote operation system comprising: an operation target device including a control unit that changes display on the display screen based on a signal received by the reception unit.

  According to the present invention, by opening and closing the lid, it is possible to switch between an operation by an operator attached to the lid and an operation by an external position indicator, and the user selects a desired operation method. Can be operated. Thereby, the position input operation with respect to various devices can be easily performed, and even a device having a complicated function can be easily operated.

[First Embodiment]
FIG. 1 is an external perspective view showing a configuration of a remote control device 2 according to a first embodiment to which the present invention is applied.
The remote controller 2 shown in FIG. 1 is used for remote operation of a television receiver or a personal computer as will be described later, and has a size and shape suitable for a user to hold and operate with one hand.

As shown in FIG. 1, the remote control device 2 includes a position input operation unit (position input device) 22, a key switch unit 24, a power switch 25, and an LED (Light Emitting Diode) 26 on the upper surface of the remote control device main body 21. Is provided.
The position input operation unit 22 is positioned substantially at the center of the upper surface of the remote control device main body 21 and includes an operation protrusion 23 (operation protrusion). The operation protrusion 23 is, for example, in a position where the user can touch with the thumb while holding the remote control device 2 in his hand.
In the position input operation unit 22, a surface plate (lid) 211 (FIG. 2) that constitutes the upper surface of the remote control device main body 21 is provided with a substantially rectangular hole 22A, and an operation protrusion 23 projects from the hole 22A. The operation protrusion 23 can be slid inside the hole 22A.
The key switch unit 24 includes one or more switches. The power switch 25 is a switch for instructing the target device operated by the remote control device 2 to turn on / off the power. The LED 26 functions as an indicator that indicates the operating state of the remote control device 2, and is turned on, for example, during the operation of the remote control device 2, and is turned off when the remote control device 2 is not operated for a certain period of time.

  FIG. 2 is a cross-sectional view of the main part showing the configuration of the position input operation unit 22 in detail. The cross section of the operation projection 23 is shown in detail in FIG. 3 and is not shown in FIG.

  As shown in FIG. 2, the remote control device main body 21 has a substantially box-shaped cross-sectional shape with the front plate 211 as the upper surface and the back plate 212 as the back surface. One side surface of the remote control device body 21 is composed of an upper plate 213A and a lower plate 214A, and the other side surface is composed of an upper plate 213B and a lower plate 214B. Then, in a space surrounded by the front plate 211, the back plate 212, the upper plates 213A and 213B, and the lower plates 214A and 214B, a sensor board (sense part) 218 and a flat base (above the sensor board 218) The flat plate portion 231 is accommodated in an overlapping manner, and the operation projection 23 is erected on the flat base 231.

The sensor substrate 218 is a substrate composed of a plurality of layers, and loop coil groups 241 and 242 (FIG. 5) to be described later are formed. The sensor substrate 218 is fixed to the back plate 212.
Further, the flat base 231 is positioned so as to be sandwiched between the sensor substrate 218 and the back surface of the front plate 211. The hole 22A provided in the front plate 211 is smaller than the sensor substrate 218, and the flat base 231 is larger than the hole 22A and smaller than the sensor substrate 218. For this reason, the flat pedestal 231 can be moved in any direction along the surface of the sensor substrate 218, and does not fall out of the hole 22A.
A support plate 217 is provided between the flat base 231 and the sensor substrate 218. The support plate 217 is fixed to the upper plate 213A and the upper plate 213B, and supports the flat base 231 from the back plate 212 side, that is, from below. The support plate 217 is desirably one that does not interfere with position detection operation by a sensor substrate 218 described later, and a preferable example is an insulator such as a synthetic resin.
As described above, the flat base 231 is disposed between the surface plate 211 and the sensor substrate 218 and is supported by the support plate 217 so as to be slidable along a plane parallel to the sensor substrate 218.

A friction material 219 is attached to a surface where the flat base 231 and the back surface of the front plate 211 are in contact with each other. The friction material 219 is a sheet or a plate-like member made of a material having a predetermined friction coefficient. When the flat pedestal 231 moves in the horizontal direction, moderate friction is generated by the friction material 219, so that there is an effect of increasing the stability during the operation of moving the operation protrusion 23. In addition, it is set as the structure which has arrange | positioned the film | membrane etc. which have a predetermined friction coefficient like the friction material 219 on the surface of the support plate 217 located under the flat base 231, or the support plate 217 itself has a predetermined friction coefficient. As a thing, you may make it produce moderate friction at the time of the movement of the flat base 231.
Here, the planar shapes of the sensor substrate 218 and the flat pedestal 231 are arbitrary, and may be any shape such as a circle, an ellipse, and a rectangle. In the first embodiment, the sensor substrate 218 is used. An example in which the rectangle is rectangular will be illustrated and described.

  The operation protrusion 23 includes a substantially cylindrical shaft portion 232 erected on the flat base 231, and a contact surface portion 233 disposed so as to cover the upper surface of the shaft portion 232. The contact surface portion 233 is formed as a curved surface that is concave upward, and a plurality of anti-slip protrusions 233A are formed. The contact surface portion 233 is a surface with which a user's finger comes into contact when operating the remote control device 2, and by providing the anti-slip protrusion 233 </ b> A, it is possible to prevent slipping during the operation and realize good operability.

FIG. 3 is a principal cross-sectional view showing a detailed configuration of the operation protrusion 23, and particularly shows a cross section of the shaft portion 232 and the contact surface portion 233.
As shown in FIG. 3, the shaft portion 232 of the operation protrusion 23 is hollow, and the tact switch 240 and the ferrite core 236 are stacked and accommodated in this space in order from the bottom. The upper end of the ferrite core 236 is in contact with the top surface of the space via the spacer 239.

The tact switch 240 is a switch that is bent and deformed to a predetermined pressing force, is turned on, and returns when the pressing force is removed. Since the tact switch 240 is sandwiched between the top surface and the bottom surface of the space in the shaft portion 232 via the spacer 239 and the ferrite core 236, when the contact surface portion 233 is pressed, a pressing force is applied to the tact switch 240. Join and turn on. At this time, since the tact switch 240 performs a click operation, the user's hand operating the contact surface portion 233 feels a click feeling.
Here, it is preferable that the material constituting the shaft portion 232 is elastic enough to be bent by a predetermined pressing force, because the tact switch 240 is reliably turned on by pressing the operation projection 23.

A coil 235 is wound around a substantially cylindrical ferrite core 236. The coil 235 is connected in parallel with the capacitor 237 (FIG. 5) and further connected to the IC 238 (FIG. 5). The capacitor 237 and the IC 238 are mounted on, for example, a substrate (not shown) disposed in the space in the shaft portion 232.
The coil 235, the capacitor 237, and the IC 238 constitute an operation side circuit 234. The operation side circuit 234 generates an electromagnetic induction action between the loop coil groups 241 and 242 (FIG. 5) provided on the sensor substrate 218 (FIG. 2), as will be described later. Based on this electromagnetic induction action, the position of the operation side circuit 234 on the sensor substrate 218, that is, the position of the operation projection 23 is detected.
Thereby, the user who operates the remote control device 2 can perform a position input operation by sliding the operation protrusion 23 to an arbitrary position.

As shown in FIG. 2, the upper side plate 213 </ b> A and the lower side plate 214 </ b> A constituting one side surface of the remote control device main body 21 are rotatably connected via a hinge 215. Further, the upper plate 213B and the lower plate 214B constituting the other side surface of the remote control device main body 21 are connected via a locking piece 216, and this locking piece 216 is detachable from the lower plate 214B. is there.
With this configuration, the surface plate 211 can be rotated about the hinge 215 by removing the locking piece 216 from the lower plate 214B. As described above, since the support plate 217 is fixed to the upper plates 213A and 213B, when the front plate 211 is rotated, the upper plates 213A and 213B, the operation protrusions 23, the flat base 231 and the support plate 217 are used. However, it moves integrally with the surface plate 211.
Further, in the vicinity of the hinge 215, a switch 261A is disposed between the upper plate 213A and the lower plate 214A. This switch 261A is a switch that is turned on when the upper plate 213A and the lower plate 214A are close to each other and turned off when they are separated from each other, and can detect the opening / closing of the front plate 211 based on the ON / OFF state of the switch 261A.

FIG. 4 is an external perspective view showing a state in which the front plate 211 is opened.
As shown in FIG. 4, when the surface plate 211 is rotated about the hinge 215, the sensor substrate 218 is exposed on the upper surface of the remote control device main body 21. In this state, since the operation projection 23 is separated from the sensor substrate 218, a position input operation cannot be performed using the operation projection 23, but a position input operation can be performed on the exposed sensor substrate 218 using the input pen 27.

The position indicator 27 has a main body shaped like a writing instrument, and a core 271 projects from the tip of the main body. Also, two switches 272 and 273 are arranged side by side on the side of the main body of the position indicator 27.
The position indicator 27 incorporates an indicator side circuit 275 (FIG. 5), which will be described later, in the main body. By the function of the indicator side circuit 275, a pressing force (writing pressure) applied to the core 271 and a switch 273 are provided. 274, the operation state is detected.
The operation by the position indicator 27 is performed by holding the main body of the position indicator 27 in the hand so that the user holds the pen and bringing the lead 271 into contact with or pressing the sensor substrate 218. By this operation, the position (operation position) where the core 271 is in contact with the sensor substrate 218 is detected.

  A position detection circuit (position detection means) 20 for detecting a position input operation by the position input operation unit 22, the operation protrusion 23 and the position indicator 27 of the remote control device 2 is provided. The position detection circuit 20 is embedded below or on the side of the sensor substrate 218, for example. The position detection circuit 20 will be described below.

FIG. 5 is a diagram showing the configuration of the position detection circuit 20 in detail. For convenience of understanding, FIG. 5 includes loop coil groups 241 and 242 disposed on the sensor substrate 218 (FIG. 2), an operation side circuit 234 built in the operation protrusion 23 (FIG. 1), and An indicator side circuit 275 built in the position indicator 27 (FIG. 4) is shown together with the position detection circuit 20.
The operation side circuit 234 incorporated in the operation protrusion 23 has a configuration in which the above-described coil 235 and capacitor 237 are connected in parallel and an IC 238 is further connected. The indicator side circuit 275 built in the position indicator 27 has a configuration in which a coil 276 housed near the tip of the main body of the position indicator 27 and a capacitor 277 are connected in parallel, and further an IC 278 is connected. .

In the sensor substrate 218, an XY orthogonal coordinate system composed of an X axis and a Y axis is virtually set corresponding to the horizontal direction and the vertical direction, and a loop coil group corresponding to the XY orthogonal coordinate system. 241 and 242 are arranged. Here, since the hole 22A is formed in a substantially rectangular shape like the sensor substrate 218, the XY orthogonal coordinate system also corresponds to the vertical direction and the horizontal direction of the hole 22A. The loop coil group 241 includes a plurality of loop coils extending in the Y direction along the X direction. The loop coil group 242 includes a plurality of loop coils extending in the X direction along the Y direction. They are arranged. Each loop coil of the loop coil groups 241 and 242 is a coil of one or a plurality of turns (for example, two turns) made of a conductor, and is formed by a technique such as etching.
The loop coils of the loop coil groups 241 and 242 are connected to the position detection circuit 20.

The position detection circuit 20 is connected to each loop coil of the loop coil groups 241 and 242, and a selection circuit 252 that selects one loop coil from these loop coils, and an oscillation signal for the loop coil selected by the selection circuit 252 And a transmission / reception switching circuit 253 that switches between a transmission mode for transmitting the signal and a reception mode for receiving a signal by the loop coil selected by the selection circuit 252.
In addition, the position detection circuit 20 has a control circuit 251 that controls each part of the position detection circuit 20, an amplification circuit 254 that amplifies the signal output from the transmission / reception switching circuit 253, and a signal amplified by the amplification circuit 254 with respect to a predetermined value. A BPF (band-pass filter) 255 that passes only the signal component of the frequency band, a detection circuit 256 that converts the signal component that has passed through the BPF 255 into a voltage value, a sample-and-hold circuit 257 that holds this voltage value for a predetermined time, and a sample An A / D conversion circuit 258 that converts the voltage value held in the hold circuit 257 into digital data and outputs the digital data to the control circuit 251; a signal generation circuit 259 that generates an oscillation signal of a predetermined frequency in accordance with the control of the control circuit 251; Amplification for amplifying the oscillation signal generated by the signal generation circuit 259 and outputting it to the transmission / reception switching circuit 253 It includes a road 260.

The position detection circuit 20 detects the operation by the operation protrusion 23 and the position indicator 27 as follows.
First, the control circuit 251 controls the selection circuit 252 to select one loop coil from the loop coil groups 241 and 242 and controls the transmission / reception switching circuit 253 to switch the operation mode to the transmission mode.
Subsequently, the control circuit 251 controls the signal generation circuit 259 to generate an oscillation signal having a predetermined frequency. This oscillation signal is amplified by the amplifier circuit 260 and input to the selection circuit 252 via the transmission / reception switching circuit 253, and from the loop coil selected by the selection circuit 252 to the operation side circuit 234 or the indicator side circuit 275. Sent.

Here, when the operation by the operation protrusion 23 is performed, in the operation side circuit 234, an induced current flows through the coil 235 based on the signal transmitted from the loop coil of the sensor substrate 218, and the IC 238 starts operation. . The IC 238 generates an oscillation signal having a predetermined frequency for the coil 235 and the capacitor 237, and transmits the oscillation signal from the coil 235 to the sensor substrate 218.
Further, when the operation by the position indicator 27 is performed, in the indicator side circuit 275, an induced current flows through the coil 276 based on a signal transmitted from the loop coil of the sensor substrate 218, and the IC 278 starts operation. To do. The IC 278 generates an oscillation signal having a predetermined frequency for the coil 276 and the capacitor 277, and transmits the oscillation signal from the coil 276 to the sensor substrate 218.

On the other hand, the control circuit 251 of the position detection circuit 20 switches the operation mode to the reception mode by controlling the transmission / reception switching circuit 253 after continuing the operation in the transmission mode for a predetermined time. By this switching, the oscillation signal from the signal generation circuit 259 is not output to the selection circuit 252.
In the reception mode, the oscillation signal transmitted from the coil 235 or the coil 276 is received by the loop coil selected by the selection circuit 252, amplified by the amplification circuit 254, and then only a component in a predetermined frequency band by the BPF 255. Is output to the detection circuit 256. This signal component is converted into a voltage value by the detection circuit 256 and held in the sample hold circuit 257. The voltage value held in the sample hold circuit 257 is converted into digital data by the A / D conversion circuit 258 every predetermined time and is output to the control circuit 251.

  Then, the control circuit 251 performs arithmetic processing on the digital data input from the A / D conversion circuit 258 while sequentially selecting the loop coils of the loop coil groups 241 and 242 by the selection circuit 252, thereby operating the operation protrusion 23 or the core. A loop coil close to 271 is specified, and the absolute coordinates of the specified position are obtained.

  When the operation is performed by the operation protrusion 23, the IC 238 of the operation side circuit 234 detects the operation state (ON / OFF) of the tact switch 240 (FIG. 3) while the induced current flows through the coil 235, In accordance with this operation state, the transmission timing and transmission time of the oscillation signal to the coil 235 and the capacitor 237 are changed. This change in the sending timing and sending time is reflected when the voltage value held in the sample hold circuit 257 is converted into digital data by the A / D conversion circuit 258. Then, the control circuit 251 acquires the operation state of the tact switch 240 by performing arithmetic processing on the digital data input from the A / D conversion circuit 258.

  Further, when the operation is performed by the position indicator 27, the IC 278 of the indicator side circuit 275 detects the pressing force applied to the core 271 while the induced current flows through the coil 276, and the switches 273 and 274 The operation state is detected, and the transmission timing and transmission time of the oscillation signal to the coil 276 and the capacitor 277 are changed according to the operation state. This change in the sending timing and sending time is reflected when the voltage value held in the sample hold circuit 257 is converted into digital data by the A / D conversion circuit 258. Then, the control circuit 251 obtains the pressing force applied to the core 271 and the operation state of the switches 273 and 274 by performing arithmetic processing on the digital data input from the A / D conversion circuit 258.

  As described above, the control circuit 251 determines the operation position, the operation state of the tact switch 240, the pressing force applied to the core 271 and the operation state of the switches 273 and 274 when operated by the operation protrusion 23 or the position indicator 27. get.

By the way, when the operation projection 23 is operated with the front plate 211 closed (FIG. 1), the region where the operation projection 23 can be moved is inside the hole 22A. On the other hand, when the operation with the position indicator 27 is performed with the surface plate 211 open (FIG. 4), the area that can be operated with the position indicator 27 is the entire sensor substrate 218 exposed on the upper surface of the remote control device main body 21. is there. Therefore, the size of the operable region differs between the state in which the front plate 211 is closed and the state in which the front plate 211 is opened. As described above, the position detection circuit 20 detects the operation position by the operation protrusion 23 or the position indicator 27 as an absolute position. For this reason, it is desirable to switch the area used as the reference | standard which calculates | requires an absolute coordinate corresponding to the area which can be operated is different.
Therefore, the position detection circuit 20 includes an open / close detection circuit 261 that detects the open / closed state of the surface plate 211 based on the state (ON / OFF) of the switch 261A (FIG. 2).

When the position detection circuit 20 detects that the surface plate 211 is opened by the open / close detection circuit 261, the position detection circuit 20 determines that the operation on the sensor board 218 is an operation by the position indicator 27, and detects an operation on the sensor board 218 ( The detection area is set to an area corresponding to the area of the sensor substrate 218 exposed when the front plate 211 is opened.
Further, when the position detection circuit 20 detects that the surface plate 211 is closed by the open / close detection circuit 261, the position detection circuit 20 determines that the operation with respect to the sensor substrate 218 is an operation with the operation protrusion 23, and detects an operation on the sensor substrate 218. The (detection area) is set to an area corresponding to the movable range of the operation protrusion 23.
Further, during the opening / closing operation of the surface plate 211, the operation protrusion 23 moves away from or close to the sensor substrate 218. If the position of the operation protrusion 23 is detected by the position detection circuit 20 while the operation protrusion 23 is moving, the movement of the operation protrusion 23 unintended by the user is detected. Therefore, the position detection circuit 20 stops the position detection operation of the operation protrusion 23 while the front plate 211 is opened and closed.
FIG. 6 shows a series of operations of the position detection circuit 20 that accompany the opening and closing of the surface plate 211.

  FIG. 6 is a flowchart showing the operation of the position detection circuit 20 when the front plate 211 is opened and closed. The operation shown in FIG. 6 is performed when the open / close detection circuit 261 (FIG. 5) detects opening / closing of the surface plate 211, that is, an operation of closing the opened surface plate 211 and an operation of opening the closed surface plate 211. In addition, the process is executed based on a signal input from the open / close detection circuit 261 to the control circuit 251.

  Based on the signal input from the open / close detection circuit 261, the control circuit 251 determines whether or not there is an opening operation for opening the front plate 211 (step S11). Here, when the opening operation is performed and the surface plate 211 is changed from the closed state to the opened state (step S11; Yes), the control circuit 251 performs the position detection operation using the loop coil groups 241 and 242. Stop for a predetermined time (step S12). The predetermined time may be longer than the time from when the user starts the operation of opening the surface plate 211 to when it is completed. Specifically, from the start of the operation of opening the surface plate 211, the operation protrusion 23 is moved to the sensor substrate 218. As long as it takes longer than the region where the position can be detected, the time required to go outside is sufficient. Therefore, it may be set in advance to an average time that is considered to be required for the user to open and close the surface plate 211, or a time (for example, about 1 second to several seconds) that has a margin for this time.

  Subsequently, the control circuit 251 performs a process of setting a large detection area for position detection on the sensor substrate 218 in response to the opening of the surface plate 211 and the exposure of the sensor substrate 218 (step S13). The position detection operation is resumed (step S14).

Further, when the position detection operation is restarted in step S14, or when the opening operation of the surface plate 211 is not detected in step S11, the control circuit 251 determines whether or not there is a closing operation for closing the surface plate 211 (step S11). S15). Here, when the closing operation is performed and the surface plate 211 is changed from the opened state to the closed state (step S15; Yes), the control circuit 251 performs a position detection operation using the loop coil groups 241 and 242 in a predetermined manner. The time is stopped (step S16). Here, like the predetermined time in step S12, the predetermined time is preferably longer than the time from when the user starts the operation of closing the surface plate 211 to when it is completed.
Subsequently, the control circuit 251 performs a process of setting a small detection area for position detection on the sensor substrate 218 in response to the operation of the operation projection 23 being performed when the surface plate 211 is closed (step S <b> 25). S17), the position detection operation is resumed (step S18).

  In the above operation, when the control circuit 251 expands the detection area in step S13, all the loop coils, preferably all of the loop coils arranged in the sensor substrate 218, of the loop coil groups 241 and 242 included in the sensor substrate 218 are provided. Position detection using a loop coil is performed. On the other hand, when the control circuit 251 reduces the detection area in step S <b> 17, position detection is performed using only the loop coil that overlaps the movable region of the operation protrusion 23 in the loop coil groups 241 and 242 provided in the sensor substrate 218. It becomes like this.

  When a position input operation by the position indicator 27 is performed, the absolute coordinates of the position of the core 271 in the enlarged detection area are obtained, and when a position input operation by the operation protrusion 23 is performed, it corresponds to the size of the hole 22A. Thus, the absolute coordinates of the position of the operation protrusion 23 in the reduced detection area are obtained. Thus, since the absolute position coordinates in the effective detection area are obtained as the surface plate 211 is opened and closed, the user performs an accurate position input operation regardless of which of the position indicator 27 and the operation protrusion 23 is used. be able to. In addition, since the operation range that the user is aware of corresponds to the detection area well, there is no sense of incongruity during operation.

  FIG. 6 shows an example in which the control circuit 251 repeatedly executes a routine at predetermined time intervals to detect the presence / absence of input from the open / close detection circuit 261. However, the present invention is not limited to this. For example, the control circuit 251 may perform interrupt processing based on an input signal from the open / close detection circuit 261.

Based on the displayed information, the instruction content by the position input operation is determined, and an operation corresponding to the determined instruction content is performed. Further, when a signal indicating the operation state of the switch of the key switch unit 24 is input from the light receiving unit 33, the control unit 31 determines the instruction content and performs an operation corresponding to the determined instruction content. As a result, the remote control device 2 can perform operations on the menu screen of the television receiver 3 (such as selection of items in the menu screen).

  In addition, when a signal for displaying a screen is input from the computer 4, the video signal generation unit 34 included in the television receiver 3 generates display information based on this signal and outputs the display information to the display screen 35. The screen of the computer 4 is displayed on the display screen 35.

Process various data. Further, during execution of the basic control program and the application program, the CPU 41 generates screen display data for displaying a screen related to the program and outputs the screen display data to the display unit 48, and the television receiver 3 displays the screen. Display.
Further, when a signal indicating the position detected by the position detection circuit 20 of the remote control device 2 is input from the input unit 45, the CPU 41 is based on the operation information and the screen display data output to the display unit 48. Then, the instruction content by the position input operation is determined, and an operation corresponding to the determined instruction content is performed.
Furthermore, when a signal indicating the operation state of the switch of the key switch unit 24 of the remote control device 2 is input from the input unit 45, the CPU 41 determines the instruction content by the operation of the key switch unit 24, and the determined instruction content The operation corresponding to is performed.
As a result, the position input operation on the computer 4 can be performed by the remote control device 2.

  During operation of the computer 4, a screen related to an application program being executed by the computer 4 is displayed on the display screen 35 of the television receiver 3. Here, various menu screens and GUI (Graphical User Interface) screens are displayed on the display screen 35, and a pointer 30A is displayed as illustrated in FIG. In this state, it is possible to perform a menu selection operation, an icon selection operation on the GUI, and the like by moving the pointer 30A to an arbitrary position and further operating a switch or the like. For this reason, in the position input operation unit 22 of the remote control device 2, an operation of moving the operation projection 23 to an arbitrary position or an operation of designating an arbitrary position on the sensor substrate 218 by the position indicator 27 is substantially performed.

Therefore, the television receiver 3 and the computer 4 having complicated functions can be easily operated.

In the first embodiment, the remote control device 2 has been described as transmitting a signal to the computer 4 by emitting infrared light from the light emitting unit 203. However, the present invention is not limited to this.

[Second Embodiment]
FIG. 9 is a cross-sectional view of a principal part particularly showing the configuration of the position input operation unit 27 in the remote control device 2 according to the second embodiment to which the present invention is applied.
The remote control device 2 according to the second embodiment has components common to the remote control device 2 according to the first embodiment, and these common components are denoted by the same reference numerals and illustrated. Description is omitted.

  The remote control device 2 shown in FIG. 9 is provided with an operation position display (operator) 281 substantially at the center of the flat base 231 of the position input operation unit 22. The operation position display 281 displays characters, symbols, or designs on the flat base 231 by a method such as printing, application, or pasting. The operation position display 281 is a position where the user touches the finger when operating the remote control device 2, and the characters, symbols or symbols of the operation position display 281 are for clearly indicating the operation position to the user. .

  In the portion where the operation position display 281 is formed, an operation side circuit 234 (FIG. 5) is embedded in the flat base 231. The remote control device 2 can detect the position of the operation position display 281 on the sensor board 218, and the user can input a position by sliding the flat base 231 by touching the operation position display 281 with a finger. The operation can be performed.

  Here, the operation position display 281 may be made of the same material as the other parts of the flat pedestal 231, or made of a material that produces a tactile sensation different from the other parts of the flat pedestal 231. It may be a thing. Furthermore, the operation position display 281 is made of a material that generates a predetermined friction, or a material that easily generates friction is applied to or adhered to the operation position display 281 to prevent finger slipping during operation. May be.

In the remote control device 2 according to the second embodiment, the surface plate 211 is disposed so as to be slidable along the longitudinal direction of the remote control device main body 21. A state in which the surface plate 211 is slid is shown in FIG.
As shown in FIG. 10, the surface plate 211 slides so that the portion including the flat base 231 disposed below the surface plate protrudes from the longitudinal end of the remote control device main body 21. In the state shown in FIG. 10, the sensor substrate 218 is exposed on the upper surface of the remote control device main body 21, and a position input operation by the position indicator 27 can be performed on the sensor substrate 218.

  Further, the remote control device 2 may be provided with a switch equivalent to the switch 261A (FIG. 2) at a position where the slide movement of the surface plate 211 can be detected. In this case, if this switch is connected to the open / close detection circuit 261 (FIG. 5), the position detection circuit 20 switches the detection area according to the open / closed state of the front plate 211, and the position during the open / close operation of the front plate 211. Processing to stop detection can be performed.

That is, by using the remote control device 2 according to the second embodiment, the operation using the operation protrusion 23 and the operation using the position indicator 27 can be easily switched. Further, by adopting a configuration in which the operation projection 23 is eliminated from the position input operation unit 22, there is an advantage that there is no portion protruding in the thickness direction of the remote control device main body 21, and that the remote control device 2 having an excellent storage property can be realized. is there.

[Third Embodiment]
FIG. 11 is a cross-sectional view of the main part showing the configuration of the position input operation unit 25 included in the remote control device according to the third embodiment to which the present invention is applied, and FIG. 12 is a plan view of the main part.
The position input operation unit 25 shown in FIGS. 11 and 12 has a configuration that replaces the position input operation unit 22 in the first and second embodiments described above.

In the position input operation unit 25, a frame composed of slide support members 222 and 223 is provided on the upper plates 213A and 213B above the hinge 215, and the operation protrusion 23 is supported inside the frame. . Here, the wire 221 and the slide support members 222 and 223 constitute a support mechanism.
The position input operation unit 25 in the third embodiment is common to the position input operation unit 22 in the first and second embodiments except for the wires 221 and the slide support members 222 and 223. is there. These common components are denoted by the same reference numerals and description thereof is omitted.

  The slide support members 222 and 223 are rod-shaped members having grooves formed along the longitudinal direction thereof. As shown in FIG. 12, the slide support members 223 are respectively disposed at both end portions of the position input operation unit 25 along the longitudinal direction of the remote control device 2, and the slide support members 222 are orthogonal to the slide support members 223. Are arranged at the front end portion and the rear end portion of the position input operation unit 25 respectively. The grooves formed in the slide support members 222 and 223 are arranged so as to open toward the inside of the position input operation unit 25. Since the end portions of the adjacent slide support members 222 and 223 are joined, coupled, or in contact with each other, the two slide support members 222 and the two slide support members 223 surround the position input operation unit 25. A square frame is formed. A frame formed by the slide support members 222 and 223 is covered with a surface plate 211.

Then, the operation projection 23 is suspended by a wire 221 inside the frame made up of the slide support members 222 and 223. As shown in FIG. 12, the position input operation unit 25 is provided with two sets of wires 221 each having two sets, for a total of four sets. Among these, one set of wires 221 is disposed across two slide support members 222, and the other set of wires 221 is disposed across two slide support members 223. As described above, grooves are formed in the slide support members 222 and 223, and the grooves open toward the inside of the frame. The end of the wire 221 is accommodated in this groove, and the two sets of wires 221 are slidable along the grooves of the slide support members 222 and 223, respectively.
Further, the two sets of wires 221 both pass through the through hole 232A formed in the shaft portion 232 of the operation projection 23. The through hole 232A and the wire 221 are not fixed and are slidable. In the shaft portion 232, two sets of wires 221 are orthogonal to each other.

According to this configuration, the wire 221 and the slide support member 222, the wire 221 and the slide support member 223, and the wire 221 and the shaft portion 232 can slide. For this reason, the operation protrusion 23 is supported so as to be freely movable along the surface of the sensor substrate 218 in the longitudinal direction of the slide support member 222 and the longitudinal direction of the slide support member 223 orthogonal to this direction. Therefore, the operation protrusion 23 can freely move along the surface of the sensor substrate 218. At this time, the wire 221 slides along the slide support member 222 or the slide support member 223 while sliding in the through hole 232A, so that the movement of the operation protrusion 23 is not hindered at all.
In addition, since the operation projection 23 is supported by the wire 221 at a position floating a predetermined distance from the surface of the sensor substrate 218, friction between the lower surface of the shaft portion 232 and the surface of the sensor substrate 218 does not occur. . For this reason, the operation protrusion 23 can be easily moved to an arbitrary position with a very small force.

Furthermore, the slide support members 222 and 223 are integrated with the upper side plates 213A and 213B and the surface plate 211, and are configured to be rotatable about the hinge 215. At this time, the operation protrusion 23 and the wire 221 are formed of the slide support member. Rotate integrally with 222 and 223. Therefore, the position input operation unit 25 can move the respective parts including the upper plates 213A and 213B upward to expose the sensor substrate 218. For example, the position indicator 27 can be exposed to the exposed sensor substrate 218. It is possible to perform a position input operation according to FIG.
Thus, according to the third embodiment, the same effects as those of the first and second embodiments described above can be obtained. Further, since the position input operation unit 25 has a simple configuration in which the operation protrusion 23 is suspended by the wire 221, it can be easily realized at low cost.

  In the above configuration, the thickness and the material of the wire 221 can be arbitrarily changed as long as the operation protrusion 23 can be supported above the sensor substrate 218 in the absence of user operation. The number is also arbitrary. Instead of the wire 221, it is also possible to use a member having an action of supporting the operation protrusion 23 by the slide support members 222, 223, for example, a metal or resin rod.

Each embodiment described above shows one embodiment of the present invention, and it is needless to say that the present invention can be arbitrarily modified and applied within the scope of the present invention.
Further, in each of the above-described embodiments, the electromagnetic force between the coil 235 of the operation side circuit 234 and the coil 276 of the indicator side circuit 275 and the loop coil groups 241 and 242 disposed on the sensor substrate 218. Although the position of the operation protrusion 23 or the core 271 is detected based on the action, the present invention is not limited to this. For example, a conductor piece is provided on the lower surface or inside a specific position of the flat base 231, a plurality of conductors insulated from each other are laid on the sensor substrate 218, and a change in capacitance between these conductors is detected, It is also possible to use a capacitance method that detects the position of the protrusion 23. In this case, the conductor piece on the flat pedestal 231 protrudes as a tapered protrusion on the surface facing the sensor substrate 213, and the conductor piece on the sensor substrate 213 is in contact with the sensor substrate 213. Therefore, the position input operation can be performed with high accuracy. Further, if the core 271 of the position indicator 27 is made of a conductor, the position of the core 271 on the sensor substrate 218 can be detected. Note that the conductor pieces of the flat base 231 and the core 271 do not need to be exposed, and the conductor pieces may be covered with resin or the like.
In addition, a pressing operation may be detected on the sensor substrate 218 by providing the sensor substrate 218 with a resistance film whose electric resistance value changes according to the pressing force. In this case, when the operation of pressing the operation protrusion 23 or the operation of pressing the sensor substrate 218 with the core 271 of the position indicator 27 is performed, the position where the pressing operation is performed can be detected. In this case, if a tapered projection is provided on the lower surface of the operation projection 23, that is, the surface facing the sensor substrate 213, and the sensor substrate 213 is pressed by the tip of this projection, the tip of the projection on the sensor substrate 213 Since the position is detected, the position input operation can be performed with high accuracy.
In any case, the same effects as those in the above embodiments can be obtained.

  Furthermore, the present invention is not limited to the remote control device 2 and can be applied to various electronic devices. That is, the present invention may be applied to a portable electronic device such as a PDA (Personal Digital Assistant) or a cellular phone, or may be applied to a notebook computer. In particular, when the position input operation unit 22 is applied to a small device suitable for carrying, the position input operation can be performed even in a limited size housing and the operation protrusion 23 is operated with a finger. The position input operation can be performed by the position indicator 27.
