The input detection unit 2 is provided so as to extend in the longitudinal direction on a wide surface of the outer surface of the portable device 1. That is, the accommodating part 30 is recessed in the outer surface of the portable device 1, and three detection switches S1, S2, S3 are provided in the accommodating part 30 in a line in a straight line in the longitudinal direction. These detection switches S1, S2, and S3 employ mechanical contacts such as micro switches (tactile switches). The opening part of the accommodating part 30 is obstruct | occluded with the cover 20 in which elastic bodies, such as a synthetic resin and rubber | gum, were formed in plate shape. The housing 20 side of the cover 20 is in contact with the actuators of the three detection switches S1, S2, S3. The cover 20 does not protrude from the surface of the portable device 1 and has the same height as the surface. When the user presses the cover 20, the input detection unit 2 is bent, the actuators of the three detection switches S <b> 1, S <b> 2, S <b> 3 are pressed, and a detection signal is output from each to the microcomputer 5.

  Each of the grip detection switches 3 and 4 is provided to extend in the longitudinal direction on a surface different from the input detection unit 2 and face each other. That is, the two accommodating portions 31 and 32 are recessed in each side surface of the portable device 1, and the detection switches 3 a and 4 a are respectively provided in the accommodating portions 31 and 32. The detection switches 3a and 4a employ mechanical contacts such as micro switches (tactile switches). The openings of the accommodating portions 31 and 32 are closed by the covers 3b and 4b formed in a plate shape. The housings 31 and 32 of the covers 3b and 4b are in contact with the actuators of the detection switches 3a and 4a. The covers 3 b and 4 b protrude from the surface of the portable device 1.

Thus, the output patterns of the detection signals from the three detection switches S1, S2, S3 differ depending on the user's input operation to the input detection unit 2.

  Then, based on the difference in the output pattern, the microcomputer 5 discriminates the contents of the remote operation and generates an operation signal to that effect. For example, when the user performs an operation of tracing from top to bottom as shown in FIG. 4A, the microcomputer 5 generates an unlocking operation signal for unlocking the door lock of the vehicle 10, and FIG. When an operation of tracing from the bottom to the top is performed as in (b), the microcomputer 5 generates a locking operation signal for locking the door lock of the vehicle 10.

Next, a processing procedure for locking and unlocking the door lock of the vehicle 10 from the portable device 1 will be described.
When the user wants to unlock the door lock of the vehicle 10, first, when the portable device 1 is taken out of the pocket and the portable device 1 is gripped, a grip detection signal is output from each of the grip detection switches 3 and 4 to the microcomputer 5.

Is done. Then, the microcomputer 5 is activated, that is, the input operation to the three detection switches S1, S2, and S3 becomes effective. When the user traces the input detection unit 2 from the bottom to the top as shown in FIG. 4B, the detection signals from the detection switches S1, S2 and S3 are output patterns based on this input operation. 5 is output. The microcomputer 5 determines that the operation is a locking operation based on the output pattern of the detection signal, generates a locking operation signal, and uses the ID code stored in the portable device 1 in the generated locking operation signal as the locking operation signal. And output to the transmission circuit 6. The transmission circuit 6 modulates the locking operation signal and outputs it via the antenna 6a.

  When the control unit 11 of the vehicle 10 receives the operation signal transmitted from the portable device 1 through the antenna 12 a as described above, the receiving circuit 12 demodulates the operation signal and outputs it to the microcomputer 13. The microcomputer 13 collates the ID code included in the operation signal with the ID code stored in the vehicle 10. Then, the microcomputer 13 controls the door lock mechanism 14 based on the operation signal when matching is performed, and locks and unlocks each door lock. That is, when the control unit 11 receives the unlocking operation signal, the door lock mechanism 14 unlocks each door lock. On the other hand, when the control unit 11 receives the locking operation signal, the door locking mechanism 14 locks each door lock.

As described above, according to the embodiment described above, the following effects can be obtained.

In addition, the said embodiment can be implemented with the following forms which changed this suitably.

  In the above embodiment, when an input operation that traces from top to bottom as shown in FIG. 4 (a) is performed on the input detection unit 2, each door lock is unlocked, and as shown in FIG. 4 (b). Thus, when an input operation that traces from the bottom to the top is performed on the input detection unit 2, each door lock is locked. However, the vehicle 10 has a detection signal output pattern according to a user's input operation. The allocation of the operation function (door lock mechanism 14) is not limited to this. For example, the input operation that traces from top to bottom may be locked, and the input operation that traces from bottom to top may be unlocked.

  In the above embodiment, the door lock / unlock of the vehicle 10 is remotely controlled. However, the input operation by the user is not limited to the door lock / unlock of the vehicle 10 but is outlined in FIG. As shown by the arrows, when the input detection unit 2 is traced from top to bottom and from bottom to top, that is, from the detection switch S1 to the detection switch S3 and from the detection switch S3 to the detection switch S1. The sliding door of the door of the vehicle 10 is opened, or the user moves the input detection unit 2 from the bottom to the top and from the top to the bottom as indicated by the white arrow in FIG. That is, when the operation of tracing from the detection switch S3 to the detection switch S1 and from the detection switch S1 to the detection switch S3 is performed, the luggage door of the vehicle 10 is opened. It may be or.

  In the above embodiment, the input operation to the input detection unit 2 is validated when a grip detection signal is output from both the grip detection switches 3 and 4 to the microcomputer 5, but the grip detection switches 3 and 4 An operation signal may be transmitted when a grip detection signal is output to the microcomputer 5 from at least one of the above. As a result, even when a grip detection signal is output from only one side depending on how to grip, it is possible to determine that the portable device 1 is being gripped and to transmit an operation signal.

In the above embodiment, the two grip detection switches 3 and 4 are provided, but only one may be provided.

The switches S11 to S18 may be associated with the operation target. Then, the microcomputer 5 may determine the remote operation depending on which detection switch S11 to S18 has output the detection signal, and generate an operation signal to that effect. For example, when an input operation is performed on the input detection unit 35 (detection switches S11 and S12), the microcomputer 5 generates an unlocking operation signal for unlocking the door lock of the vehicle 10, and the input detection unit 36 (detection). When an input operation is performed on the switches S13 and S14), a lock operation signal for locking the door lock of the vehicle 10 is generated, and an input operation is performed on the input detection unit 37 (detection switches S15 and S16). Then, a door opening operation signal for opening the sliding door of the vehicle 10 is generated, and when an input operation is performed on the input detection unit 38 (detection switches S17 and S18), a door closing operation signal for closing the sliding door of the vehicle 10 is generated. To do. According to such a configuration, it is not necessary to remember the tracing direction unless the tracing direction of the input operation is determined. Furthermore, if a mark or a character meaning an operation is attached to each of the input detection units 35, 36, 37, and 38, the input operation can be simplified without hesitation.

The remote operation content may be determined based on various input operations for .about.56, and an operation signal to that effect may be generated. For example, it becomes possible to input simple characters and symbols, and if an operation signal corresponding to this input operation is generated, crime prevention can be improved. In addition, since various input operations are possible, a large number of operations can be performed by the portable device 1. Moreover, you may enable it to lock and unlock any position on the surface in which the input detection parts 41-56 of the portable device 1 were provided. For example, when detection signals are output from a plurality of adjacent detection switches, a predetermined operation signal is generated.

  -As shown in Drawing 8, you may make it provide input detection part 2 in the side of portable machine 1 in which grip detection switch 3 was provided. According to such a configuration, since the grip direction of the grip detection switch 4 by the user and the pressing direction with respect to the input detection unit 2 face each other, an input operation is facilitated.

  In the above embodiment, when the detection signal is output from the detection switch while the grip detection signal is output from each of the grip detection switches 3 and 4, the microcomputer 5 changes the detection signal output pattern. Based on this, the remote operation content is determined, an operation signal to that effect is generated, and the operation signal is transmitted. However, the configuration may be such that the two grip detection switches 3 and 4 are not provided. According to such a configuration, an operation signal is not transmitted unless detection signals are output from at least a plurality of detection switches, so that unintended remote operation can be prevented as much as possible.
