A plurality of operation keys 12 such as are protruding so as to be movable up and down.

  In the case 11, a wiring board (not shown) having a plurality of wiring patterns formed on the upper and lower surfaces is housed, and the upper and lower surfaces of the wiring board are electrically connected and disconnected by the up and down movement of the operation keys 12. A plurality of switch contacts (not shown) are formed.

  Further, a control unit 13 such as a microcomputer, a transmission unit 14 such as an antenna, and a reception unit 15 are formed on the wiring board, and a plurality of upper electrodes 3 and lower electrodes 6 of the touch panel 8, a plurality of switch contacts, and a transmission unit. 14 and the receiving means 15 are electrically connected to the control means 13 via a wiring pattern, a film-like flexible substrate (not shown), etc., and the input device 17 is formed.

  Reference numeral 34 denotes a video device such as a television. A display means 35 such as a liquid crystal display element is formed on the front surface of the video device 34. The video device 34 and the remote control transmitter 10 constitute an electronic device.

  In the above configuration, when the remote control transmitter 10 is pointed at the video equipment 34 and a predetermined operation key 12 is pressed with a finger, the switch contacts in the case 11 are electrically connected and disconnected, and the control means is accordingly provided. 13 transmits a remote control signal of a predetermined radio wave from the transmission means 14 to the video equipment 34. For example, the video equipment 34 is turned on / off and the volume is increased / decreased by remote control.

  Further, as shown in the front view of FIG. 6A, the remote controller is displayed in a state in which menus for handwriting input such as the input unit 35A, the selection unit 35B, and the determination unit 35C are displayed on the display unit 35 of the video equipment 34. When the finger touches the upper surface of the touch panel 8 of the transmitter 10 and the finger is slid to draw, for example, the letter “P”, the capacitance between the upper conductive layer 2 and the lower conductive layer 5 at the operated position changes. Thus, the control means 13 detects the finger trajectory.

  Then, a trajectory signal corresponding to the finger sliding operation is output from the control means 13, and this trajectory signal is transmitted from the transmission means 14 to the video equipment 34 as a remote control signal, and the character “P” is input to the input unit 35 A of the display means 35. "And a cursor 36 are displayed on the selection unit 35B, and characters such as" p "," P ", and" F "whose font is similar to" P "are displayed.

  Further, in this state, when the operation key 12 for moving the cursor is pressed, the control means 13 transmits a remote control signal in response to this, and as shown in FIG. 6B, the cursor 36 moves within the selection unit 35B. Move to select the desired letter “P”.

  In this state, when the confirmation operation key 12 is pressed, a remote control signal is also transmitted from the remote control transmitter 10, and “P” is displayed on the confirmation unit 35C as shown in FIG. 6C. The handwritten input of the letter “P” is performed.

  Further, in order to continue to input the character “A” by handwriting, a finger is touched on the upper surface of the touch panel 8 and a sliding operation is first performed so as to draw a part of “A” of “A”. The control means 13 detects the finger trajectory according to the change in the capacity, and the trajectory signal is output from the control means 13 and transmitted from the transmission means 14 to the video equipment 34 as a remote control signal.

  Therefore, as shown in the front view of FIG. 3A, the input unit 35A of the display means 35 displays a trajectory display of “∧” instead of the letter “A”, and the selection unit 35B displays “A Instead of “”, characters such as “he” and “∧” whose font is similar to “∧” and the cursor 36 are displayed.

  For this reason, once the finger is released from the touch panel 8 and the “−” part of “A” is continuously drawn, when the finger is brought close again, the touch of the touch panel 8 due to the proximity of the finger is displayed. Since the capacitance between the upper conductive layer 2 and the lower conductive layer 5 changes to a value different from that when the finger touches, the control means 13 detects this and Different position signals are output from the control means 13.

  When this position signal is transmitted from the transmission means 14 to the video equipment 34 as a remote control signal, the input unit 35A of the display means 35 has, for example, a finger on the right side on the touch panel 8 as shown in FIG. ), On the right side, as shown in FIG. 3C, for example, an arrow-shaped position display 37 indicating the position of the finger on the touch panel 8 is displayed on the left side.

  That is, when a sliding operation is performed with a finger touching the touch panel 8, the control means 13 detects the finger locus and outputs a locus signal, and the locus display of “の” is displayed on the input unit 35A of the display means 35. However, when a finger is brought close to the touch panel 8, a position signal different from the trajectory signal is output from the control means 13, and a position display 37 indicating where the finger is located on the touch panel 8. Is displayed on the input unit 35A.

  Then, based on the position display 37, when the finger is brought into contact with the touch panel 8 again and sliding operation is performed so as to draw a part of “−” of “A”, the change in the electrostatic capacity is detected by the control means 13. Then, a locus signal is output, a remote control signal is transmitted from the transmission means 14, and a locus display of the character “A” is displayed on the input portion 35A of the display means 35 as shown in the front view of FIG. In addition, characters such as “A”, “Δ”, “∧”, and the like that have a similar font to “A” and the cursor 36 are displayed on the selection unit 35B.

  In this state, the cursor 36 of the selection unit 35B is at the desired character “A”, and it is not necessary to move the cursor 36. Therefore, when the operation key 12 for confirmation is pressed, the control means 13 is responded accordingly. Transmits a remote control signal, and as shown in FIG. 4B, “A” is displayed alongside “P” in the determination unit 35C, and the handwriting input of the character “A” is completed.

  That is, by pressing the plurality of operation keys 12 of the remote control transmitter 10, remote operations such as turning on / off the power of the video equipment 34 and increasing / decreasing the volume are performed, and a touch operation is performed by touching the touch panel 8 with a finger. The handwriting input of a desired character can be performed by remote operation.

  At this time, if the control means 13 of the input device 17 performs a sliding operation with the finger touching the touch panel 8, the locus of the finger is detected and a locus signal is output, and FIG. As shown in FIG. 3A, the locus display of “P” and “∧” is displayed on the input unit 35 </ b> A of the display unit 35, and when the finger is brought close to the touch panel 8, the control unit 13 This is detected and a position signal different from the trajectory signal is output, and as shown in FIGS. 3B and 3C, a position display 37 indicating the position of the finger is displayed on the input unit 35A. Thus, there is no typographical input and the handwriting input operation can be easily performed.

  That is, when a finger is brought close to the touch panel 8, a finger position display 37 is displayed on the display unit 35, and it is possible to determine where the finger is on the touch panel 8 without looking at the touch panel 8. Even when handwritten input is performed by moving operation or when the finger is once removed from the touch panel 8 and handwritten input is performed again, it is not necessary to check the position by looking at the touch panel 8 or the finger each time, and only the display means 35 is used. It is configured such that a handwriting input operation can be easily performed while watching.

  In the above description, the control unit 13 transmits a radio remote control signal to the video equipment 34 from the transmission unit 14 such as an antenna in response to a pressing operation of the operation key 12 or a sliding operation of the touch panel 8. As described above, the present invention may be applied to a configuration in which the transmission unit 14 is formed of a light emitting diode or the like and the video device 34 is remotely operated by infrared rays, or a configuration in which the reception unit 15 is used to bidirectionally communicate with the video device 34.

As shown in FIG. 4, the plurality of operation keys 12 and the touch panel 8 on the upper surface of the fixed casing 40 are operated while viewing the display means 35 such as a liquid crystal display element of the movable casing 41 that is detachably mounted on the fixed casing 40. The present invention can also be implemented in electronic devices such as personal computers.

  Furthermore, although the film-like upper substrate 1 having the upper conductive layer 2 formed on the upper surface and the lower substrate 4 having the lower conductive layer 5 formed thereon are bonded to each other, the touch panel 8 has been described. A plurality of upper conductive layers 2, lower conductive layers 5, upper electrodes 3, and lower electrodes 6 are formed on, for example, three thin plates using copper foil or the like on a thin plate of glass or epoxy containing glass, and the like. A touch panel may be formed using a so-called multilayer wiring board in which these are connected by through holes.

  As described above, according to the present embodiment, the control unit 13 outputs a position signal according to the proximity of the finger to the touch panel 8 and a trajectory signal according to the contact of the finger, and also displays the finger position on the display unit 35. When the finger is brought close to the touch panel 8 by displaying the trajectory 37 and the trajectory display, the finger position display 37 is performed on the display means 35, and the finger position can be determined without looking at the touch panel 8.
