  As shown in FIG. 2, the secondary master device 1 equipped with the input device of the present embodiment is capable of wireless communication with the master device 2 as an external device.

  The secondary master unit 1 and the master unit 2 together with the slave unit 3 and the electric lock 4 constitute a known intercom system. The subunit | mobile_unit 3 is connected to the main | base station 2 via the signal wire | line SL, and can talk with the main | base station 2. FIG. Moreover, the subunit | mobile_unit 3 has a camera (not shown), and can transmit the image signal obtained by imaging with this camera to the main | base station 2. FIG. Furthermore, the electric lock 4 is provided on, for example, a front door (not shown) and is controlled (unlocked and locked) by a control signal transmitted as an electric signal from the master unit 2 via the signal line SL. It is. Since the parent device 2, the child device 3, and the electric lock 4 as described above can be realized by a well-known technique, detailed illustration and description thereof are omitted.

  More specifically, the secondary master unit 1 includes a touch panel 11, a communication unit 12, a call unit 13, a control unit 14, and a position information acquisition unit 15.

  The touch panel 11 is formed by integrating a display 11a that displays an image and a contact sensor 11b that detects a position where the user touches the display 11a. As the display 11a of the touch panel 11, for example, a liquid crystal panel can be used. The contact sensor 11b of the touch panel 11 can be realized by a known method such as a resistive film method, an optical method, or an ultrasonic method.

  The communication unit 12 transmits and receives a wireless signal using radio waves as a medium to and from the parent device 2. Since such a communication unit 12 can be realized by a well-known technique, detailed illustration and description thereof are omitted.

  The call unit 13 is used for a call with the parent device 2. Specifically, the calling unit 13 includes a well-known microphone (not shown) that converts sound into a sound signal that is an electrical signal, and a well-known speaker (not shown) that converts an input sound signal into sound. The voice signal (hereinafter referred to as “transmission signal”) output from the microphone is amplified and input to the communication unit 12, and the voice signal input from the communication unit 12 and amplified (hereinafter referred to as “reception signal”). Is provided with a known voice switch (not shown) that selectively switches to one of the reception states to be input to the speaker. The voice switch compares the strength of the transmitted signal and the strength of the received signal in a call state started by the control of the control unit 14, and if the strength of the transmitted signal is higher than the strength of the received signal. A comparison operation is performed at any time to switch to the transmission state and to switch to the reception state when the strength of the received signal is higher than the strength of the transmitted signal. Since the call unit 13 as described above can be realized by a known technique, detailed illustration and description thereof will be omitted.

  The control unit 14 controls the display 11a of the touch panel 11, the communication unit 12, and the call unit 13. Such a control part 14 is realizable using a known microcontroller.

  The position information acquisition unit 15 acquires a distance from the parent device 2 as position information based on, for example, the strength of a wireless signal received from the parent device 2. Since such position information acquisition unit 15 can be realized by a known technique, detailed illustration and description thereof will be omitted.

  Moreover, each of the parent device 2 and the child device 3 includes a call unit (not shown) similar to that of the sub-master device 1.

  Hereinafter, the operation of the control unit 14 will be described.

  In a state in which a monitor operation, a call operation, and an electric lock display operation, which will be described later, are not performed (hereinafter, referred to as “standby state”), the control unit 14 performs 3 as shown in FIGS. The display 11a is controlled to display the buttons 61 to 63. When the contact sensor 11b detects that the user has touched any region of the buttons 61 to 63, the control unit 14 performs an operation according to the buttons 61 to 63 in which contact is detected. .

  That is, when contact in the area of a button 61 (hereinafter referred to as “camera button”) 61 corresponding to the child unit 3 is detected by the contact sensor 11b, the control unit 14 is a camera provided in the child unit 3. The communication unit 12 is controlled so as to transmit a control signal for requesting the start of transmission of an image signal obtained by imaging to the parent device 2, and an image signal transmitted from the parent device 2 in response to the control signal A monitor operation of controlling the display 11a so as to reproduce the image as an image is performed. Further, the control unit 14 displays a button for instructing the end of the monitor operation on the above-described image during the monitor operation, and transmits an image signal when contact with the button is detected during the monitor operation. The communication unit 12 is controlled so as to transmit a control signal for requesting to stop to the base unit 2, and the monitor operation is terminated to return to the standby state. In addition, when the subunit | mobile_unit 3 which has a camera is connected with two or more units, before control of the communication part 12, while interposing the operation | movement which receives selection of the subunit | mobile_unit 3, it is a control signal between the selected subunit | mobile_unit 3 In addition, the slave unit 3 used for the monitor operation may be selectable by transmitting and receiving the image signal.

  When contact in the area of the button 62 (hereinafter referred to as “indoor call button”) 62 corresponding to the parent device 2 is detected by the contact sensor 11 b, the control unit 14 communicates with the parent device 2. After transmission and reception of appropriate signals via the communication unit 12, a call operation is started in which the communication unit 12 and the call unit 13 are controlled so as to be in a call state in which a call can be made with the base unit 2. . Further, the control unit 14 controls the display 11a to display a button for instructing the end of the call operation during the call operation, and performs the call operation when contact with the button is detected during the call operation. Exit and return to standby. In addition, when the device such as the slave unit 3 connected to the base unit 1 can be selected as the target of the above-described call operation, an operation for accepting selection of the target of the call operation is performed before the control of the communication unit 12. The target of the call operation may be selectable by sandwiching and starting the call state with the selected target.

  Further, when contact in the area of the button 63 corresponding to the electric lock 4 (hereinafter referred to as “electric lock button”) 63 is detected by the contact sensor 11 b, the control unit 14 includes the communication unit 12, the base unit 2, and the like. Information on whether the electric lock 4 is unlocked or locked is acquired by communication with the electric lock 4 via the signal line SL, and the display 11a is controlled to display the acquired information. The electric lock display operation is started. In addition, the control unit 14 controls the display 11a to display a button for instructing the end of the electric lock display operation. When contact with the button is detected during the electric lock display operation, the control unit 14 performs the electric lock display operation. Exit and return to standby. Furthermore, an operation for switching the unlocking / locking of the electric lock 4 may be accepted on an image displaying the acquired information.

  Here, the control unit 14 changes the display mode of the plurality of buttons 61 to 63 displayed simultaneously according to the position information acquired by the position information acquisition unit 15.

  Specifically, when starting the standby state, the control unit 14 compares the distance from the base unit 2 as the position information acquired by the position information acquisition unit 15 with a predetermined switching distance.

  If the distance to the base unit 2 is less than the switching distance, it is unlikely that a call with the base unit 2 will be started, and therefore the possibility that the indoor call button 62 will be operated is low. Among the buttons 61 and 63, the camera button 61 that is expected to be relatively operated is displayed larger than the other two buttons 62 and 63.

  Further, when the distance to the base unit 2 is equal to or longer than the switching distance, the indoor call button 62 that is expected to be most likely to be operated is displayed larger than the other two buttons 61 and 63.

  According to the said structure, based on the positional information acquired in the positional information acquisition part 15, the area of the buttons 61-63 estimated to be the highest possibility of being selected is larger than the area of the other buttons 61-63. The operability can be improved by increasing the size and making the contact easy.
