Description

  The present invention relates to an input device including, for example, a so-called jog dial rotation key as an operation device operated by a user, and a mobile terminal such as a mobile phone terminal having the input device.

  2. Description of the Related Art Conventionally, electronic devices such as mobile phone terminals have been provided with, for example, a rotary key and a rotary encoder for detecting the rotation of the rotary key as an operation device for enabling a complicated input operation to be performed quickly and easily. Some are equipped with an operating device. For example, a so-called jog dial is known as an operation device including a rotary key and a rotary encoder.

  Here, in an operation device such as a jog dial, in order to allow the user to recognize how much the rotation key has been rotated, a click feeling is applied to the user's finger each time the rotation key is rotated several tens of degrees around the rotation axis. A mechanism for providing (operation feeling for the user to recognize the rotation) is provided.

  Conventionally, as a mechanism for giving a feeling of operation to the user, in particular, a mechanism for giving a feeling of clicking, a protrusion is provided every several tens of degrees around the rotation axis, and when the rotation key is rotated, each of the protrusions is provided. There is known a mechanism in which a spring member is provided so as to transmit a force generated by contact between the protrusion and the spring member as the rotary key rotates to a user's finger as a click feeling.

  As another configuration example, the N and S poles of the magnet are alternately arranged every several tens of degrees around the rotation axis, while the N and S magnets are approached when the rotary key rotates. A magnet with only one of the N and S poles facing each other is provided, and the repulsive force is generated when the same poles of both magnets come close to each other as the rotary key rotates, or the different poles come close and attracting force There is also known a mechanism adapted to transmit the repulsive force or suction force to the user's finger as a click feeling when the occurrence of the occurrence of the problem.

Japanese Patent Laying-Open No. 2003-337649 (FIG. 1) Japanese Patent Laying-Open No. 2004-252836 (FIGS. 5 and 6)

  By the way, in an operation device such as a jog dial provided with a rotation key, as a mechanism for giving the user a feeling of operation when the rotation key is operated, in the case of a structure combining the above-described protrusion and a spring member, for example, When dust or the like enters the rotation mechanism, the operation device may break down due to damage of, for example, a protrusion or a spring member. In addition, when aiming to reduce the size and thickness of an electronic device such as a mobile phone terminal, it is required to further reduce the size and thickness of an operation device including a rotary key. However, when the operation device is reduced in size and thickness, there is a high possibility that it is difficult to provide the above-described protrusions and spring members.

  On the other hand, in the case of the structure using the magnet, for example, even when dust or the like enters the rotation mechanism, the possibility that the operation device will be damaged or broken is low. However, since the operational feeling is given by the magnetic force (repulsive force of the magnet), the operational feeling tends to be somewhat unnatural (that is, the click feeling is unnatural) as compared with the above-described mechanism combining the protrusion and the spring member. Further, if the magnet is made small in order to reduce the size and thickness of the operation device, the magnetic force (repulsive force) may be reduced accordingly, in which case it is difficult for the user to understand the operation feeling. There is a risk of becoming.

  On the other hand, according to the techniques described in Patent Document 1 and Patent Document 2 described above, the user can obtain almost the same operation feeling as the jog dial, while the operation device has a rotation key (a rotary dial unit or a rotation dial). Since the drum portion itself is eliminated, the risk of breakage and failure is also reduced, and it is easy to realize downsizing and thinning.

  However, in the case of the techniques described in Patent Document 1 and Patent Document 2, it is determined whether or not a rotation operation with a user's finger or the like has been performed, and driving for vibrating the vibrator based on the detection output from the contact detection sensor. Since control is executed by a controller, processor, or the like based on a program, a certain amount of time lag may occur between the timing of the rotation operation by the user and the timing until the vibrator actually vibrates. In this case, there is a possibility that the user may feel a sense of incongruity although it is very slight. Furthermore, in the case of the techniques described in Patent Document 1 and Patent Document 2, since the dial portion of the jog dial is actually a fixed member that does not rotate, the user actually rotates the dial portion of the jog dial. Can not get a good feeling of operation.

  The present invention has been proposed in view of such circumstances, and an operation device having a rotation key such as a so-called jog dial is used as an operation device capable of performing a complicated input operation quickly and easily. In this case, for example, even when the operation device is downsized and thinned along with downsizing and thinning of the electronic device, it is possible to give a good operational feeling to the user, The present invention relates to an input device capable of substantially eliminating a time lag from an actual operation feeling and a portable terminal including the input device.

  The input device of the present invention is driven by an operation means having a rotary operation element, a rotation detection means for detecting a rotation operation of the rotary operation element of the operation means and outputting a rotation detection signal waveform, and a supplied drive signal. The active element is driven by a logical operation of an active element that gives a visual or tactile stimulus to the user and a rotation detection signal waveform output by the rotation detection means detecting the rotation operation of the rotary operator. By having a drive signal generation circuit unit that generates a drive signal for solving the above problem, the above-described problems are solved.

  The portable terminal of the present invention is a portable terminal including at least a rotary operation element, and is driven by a rotation detection unit that detects a rotation operation of the rotary operation element and outputs a rotation detection signal waveform, and a supplied drive signal. The active element is driven by the logical operation of the active element that gives visual or tactile stimulation to the user and the rotation detection signal waveform output by the rotation detection means detecting the rotation operation of the rotary operator. The above-described problem is solved by including a drive signal generation circuit unit that generates a drive signal for the purpose.

  That is, according to the present invention, since the drive signal for the active element is generated by the logical operation of the rotation detection signal waveform formed by the rotation operation of the rotation operator, the rotation operation by the user and the corresponding drive signal There is almost no time lag between the generation of

  In addition, according to the present invention, the active element is driven by a drive signal to give a visual or tactile stimulus to the user.

  In the present invention, when an operation device having a rotary operation device such as a so-called jog dial is used as an operation device capable of performing a complicated input operation quickly and easily, the device can be reduced in size and thickness. Accordingly, even when the operation device is reduced in size and thickness, the active element is driven according to the rotation operation of the rotary operation element to give the user a visual or tactile stimulus. Can give a good feeling of operation. Further, in the present invention, since the drive signal for the active element is generated by the logical operation of the rotation detection signal waveform formed by the rotation operation of the rotation operator, the rotation operation by the user and the actual operation feeling can be reduced. Time lag can be almost eliminated.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.
