When the notifying unit recognizes that the state of the locking unit 42 has been switched based on the information transmitted from the attachment / detachment control unit 41, the notification unit notifies that the state of the locking unit 42 has been switched.

  In addition, when the display operation unit 30 is mounted on the apparatus main body 20 and the display operation unit 30 and the apparatus main body 20 communicate with each other, the attachment / detachment control unit 21 determines that the required lock condition is satisfied. Accordingly, when the display operation unit 30 is mounted on the apparatus main body 20 and communicates with each other, the attachment / detachment control unit 41 determines that the required lock condition is satisfied, puts the lock unit 42 into a blocking state, and the display operation unit 30 is released.

Therefore, the display / operation unit 30 cannot be detached from the apparatus main body 20 during a call, so that it is possible to prevent communication from being interrupted and information from being damaged.

  The detachment control unit 41 determines that the lock release condition is satisfied when a release command is input by operating the release key 29b. The attachment / detachment control unit 41 determines that the lock release condition is satisfied when both the lock required condition and the lock release condition are satisfied. Accordingly, even when the lock unit 42 is in the blocked state, when the user operates the release key 29b, the attachment / detachment control unit 41 determines that the unlock condition is satisfied, and controls the lock unit 42 to the permitted state. Therefore, the apparatus main body 20 can be detached from the display operation unit 30 even if the amount of charge of the battery 36a is less than the separation allowance reference amount.

  The attachment / detachment control unit 41 determines that the unlocking condition is satisfied when the supply state detection unit detects that the power supply to the display operation unit 30 is stopped. As a result, the attachment / detachment control unit 41 can control the lock unit 42 to an allowable state so that the display operation unit 30 can be detached from the apparatus main body 20 even in a state where power such as a power failure is not supplied. .

Direct Current (abbreviation: DC) is electrically connected to the input unit 43a, and the other end is connected to the ground unit 43a. The first conductive path 43 has a coil 44 and a transistor 45 interposed in the middle. The DC input unit 43 a is electrically connected to the AC adapter, acquires power from the AC adapter, and transmits the power to the first conductive path 43. The ground portion 43b is connected to a conductor having a large area and applies a ground potential.

  The coil 44 is made of a conductive material, and when a current acts on the coil 44, a magnetic force is generated. The coil 44 constitutes a relay together with the switch 47 a included in the switch unit 47. The relay is a switch using an electromagnetic relay. When a current acts on the coil 44, a magnetic force is generated from the coil 44 to close the switch 7a, and when no current acts on the coil 44, the switch 47a opens.

  The transistor 44 is an NPN type bipolar transistor and can be realized by a silicon transistor. The transistor 44 has a collector 45a, a base 45b, and an emitter 45c. The collector 45 a is electrically connected to the DC input unit 43 a through the first conductive path 43. The base 45 b is connected to one end of the second conductive path 46. The emitter 45 c is connected to the ground part 43 b through the first conductive path 43.

The lock portion 48 is provided at the base end portion 56 so as to be angularly displaceable in the body of the apparatus main body 20 and is switched by angular displacement between a blocking state and an allowable state. A hook-shaped protrusion 58 is formed on the free end 57 of the lock portion 48. The display operation unit 30 is formed with an engaging protrusion 30a facing the locking means 42 when mounted on the apparatus main body 20, and the hook-shaped protrusion 58 is formed on the engaging protrusion 30a from the opposite side of the apparatus main body 20. Engagement prevents the display operation unit 30 from separating. In the permissible state, the engagement is released and the display operation unit 30 can be detached. In this way, the locking means 42 can be switched between the blocked state and the allowed state.

  The lock control unit 49 is connected to the switch unit 47. As described above, the lock control unit 49 acquires information on the open / close state of the switch 47a from the switch unit 47, and switches the state of the lock unit 48 based on the information on the open / close state of the switch 47a. When the switch 47a is closed, the lock control unit 49 switches the lock unit 48 to the blocking state. When the switch 47a is opened, the lock control unit 49 switches the lock unit 48 to an allowable state.

  Since the transistor 45 is interposed in the first conductive path 43, when a positive voltage is applied to the base 45 b by an electric signal from the second conductive path 46, a current flows in the first conductive path 43, and the first conductive path 43 The coil 44 intervening 43 generates a magnetic force and closes the switch 47b. When a negative voltage is applied to the base 45b or no voltage is applied to the base 45b by an electrical signal from the second conductive path 46, no current flows in the first conductive path 43, and the switch 47b is opened. Information on the open / close state of the switch 47b is transmitted from the switch unit 47 to the lock control unit 49, and based on this information, the lock unit 48 is switched to one of a blocking state and an allowable state.

  Accordingly, when electric power is supplied to the DC input unit 43a, an electric signal applied to a positive voltage is transmitted from the main body control unit 21 to the base 45b via the second conductive path 46. A current flows and the switch 47b is closed. Accordingly, the lock unit 48 is controlled to be in a blocking state, and prevents the display operation unit 30 from being detached from the apparatus main body 20.

  In addition, when a negative voltage is applied to the base 45b or an electric signal having a voltage of 0 is transmitted from the main body control unit 21 via the second conductive path 46, and no power is supplied to the DC input unit 43a. When power is not supplied due to a power failure, no current flows through the first conductive path 43, and the switch 47a is opened. As a result, the lock unit 48 is controlled to an allowable state, and the display operation unit 30 can be detached.

  In this way, the attachment / detachment control unit 41 determines that the required lock condition is satisfied when a current flows through the first conductive path 43, and controls the lock unit 48 to be in a blocking state so that the first conductive path 43 is electrically connected. If the lock does not flow, it is determined that the unlocking condition is satisfied, and the lock unit 48 is controlled to be in an allowable state.

Further, the output terminal 94 of the comparator 76 is connected to the charging unit sixth conductive path 86.

  The charging unit sixth conductive path 86 has one end connected to the output terminal 94 and the other end connected to the unit control unit 31. Thus, when the display operation unit 30 is attached to the apparatus main body 20, the electrical signal output from the comparator 76 is given to the attachment / detachment control unit 41 via the unit control unit 31.

  According to the present embodiment, when the battery 36 a is held by the battery holding unit 36 in the charging unit 70, the power supplied to the charging unit DC input unit 71 passes through the protection diode 72 in the charging unit first conductive path 81. Then, power is transmitted to the battery holding unit 36 to charge the battery 36a. The capacitor 74 is used to reduce noise of power transmitted from the charging unit DC input unit 71. In addition, the charging unit 70 is configured so that the power supplied from the battery 36a using the protection diode 72 and the first resistance element 73a is not transmitted to the charging unit DC input unit 71 when power is stored in the battery 36a. ing.

  Further, according to the present embodiment, in the charging unit 70, when power is transmitted to the charging unit DC input unit 71 and the battery 36a is held in the battery holding unit 36, at least one of the charging unit DC input unit 71 and the battery 36a. Is transmitted to the charging unit first conductive path 81 and the charging unit second conductive path 82, and a potential difference is generated between the charging unit first conductive path 81 and the charging unit second conductive path 82. Thus, the charging unit first conductive path in the charging unit fourth conductive path 84, the charging unit fifth conductive path 85, and the comparator 76 connected in parallel between the charging unit first conductive path 81 and the charging unit second conductive path 82. A voltage is generated between each connection part connected to 81 and the charging part second conductive path 82.

  The voltage value at the positive phase input terminal 91 is defined as a positive phase input voltage value V1. The voltage value at the negative phase input terminal 92 is defined as a negative phase input voltage value V2. Since the Zener diode 75 is interposed in the charging unit fourth conductive path 84, the charging unit fourth conductive path 84 is connected between the connection part of the charging unit first conductive path 81 and the charging unit second conductive path unit 82. When a voltage equal to or higher than a predetermined voltage is applied, the positive phase input voltage value V1 at the positive phase input terminal 91 of the comparator 76 becomes a constant value regardless of the magnitude of the current. In addition, since the third resistance element 73c and the fourth resistance element 73d are interposed in the charging unit fifth conductive path 85, the voltage at the negative phase input terminal 92 of the comparator 76 is the same as that of the charging unit of the charging unit fifth conductive path 85. It is determined by the voltage generated between the connection portions of the first conductive path 81 and the charging unit second conductive path 82 and the resistance values of the third resistance element 73c and the fourth resistance element 73d. Therefore, when the charge amount of the battery 36a increases, the voltage applied to the connection section of the charging unit fifth conductive path 85 increases, and thus the negative phase input voltage value V2 increases.

  In the comparator 76, the voltage value of the positive power supply terminal 93a is defined as a positive power supply voltage value VCC, and the voltage value of the negative power supply terminal 93b is defined as a negative power supply voltage value VEE.

  The comparator 76 compares the magnitude of the positive phase input voltage V1 input from the positive phase input terminal 91 and the negative phase input voltage V2 input from the negative phase input terminal 92, and the positive phase input voltage value V1 is the negative phase. When the input voltage V2 is larger than the output voltage, an electrical signal applied to the positive power supply voltage value VCC is output from the output terminal 94. When the positive phase input voltage value V1 is smaller than the negative phase input voltage value V2, the negative power supply voltage is output from the output terminal 94. An electrical signal applied to the value VEE is output.

  The positive phase input voltage value V <b> 1 becomes a constant value when a predetermined voltage such that the voltage of the Zener diode 75 becomes a constant value is generated between the connecting portions of the charging unit fourth conductive path 84. Further, the negative phase input voltage value V2 increases as the charge amount of the battery 36a increases. Accordingly, when a voltage equal to or higher than a predetermined voltage value is applied between the charging unit fourth conductive path 84, the comparator 76 causes the charge amount to be less than the positive phase input voltage value V1 at the negative phase input terminal 92. When the charge amount is less than the reference value for preventing separation, an electrical signal applied to the positive power supply voltage value VCC is output from the output terminal 94. Further, the comparator 76 is applied to the negative power supply voltage value VEE when the charge amount is an amount capable of generating a voltage equal to or higher than the positive phase input voltage value V1 at the negative phase input terminal 92, that is, equal to or greater than the detachment allowable reference amount. An electrical signal is output from the output terminal 94.

  As described above, the state of the lock means 42 can be controlled by the electric signal transmitted to the second conductive path 46 included in the attachment / detachment control unit 41, and therefore the output electric signal is transmitted to the unit connection unit 33 and the main body. When transmitted to the attachment / detachment control unit 41 via the connection unit 27, the state of the lock means 42 can be controlled by the electric signal.

  Further, the negative phase input voltage value V2 at the negative phase input terminal 92 is obtained by replacing the third resistance element 73c and the fourth resistance element 73d with resistance elements having different resistance values even when the charge amount of the battery 36a is the same. Since the negative phase input voltage V2 can be set to an arbitrary voltage value, the separation prevention reference amount and the separation allowance reference amount can be set to an arbitrary charge amount. Alternatively, the third resistance element 73c and the fourth resistance element 74c may be variable resistors, and the unit controller 31 may control the resistance value of the variable resistance. In this case, the user is caused to input the resistance value of the variable resistor using the display unit 39 and the unit operation key 38a, and information on the resistance value is transmitted to the unit control unit 31, so that the third resistance element and the fourth resistance value are transmitted. Control the resistance of the element. This makes it possible to set the separation element reference amount and the separation allowance reference amount using the display unit 39 and the unit operation keys.

  In this way, charging of the battery 36a, detection of the charge amount of the battery 36a, and control of the lock means 42 based on the charge amount of the battery 36a are realized.

  In the charging unit 70, when power is not transmitted from the charging unit DC input unit 71, the comparator 76 does not output an electrical signal from the output terminal 94 and does not transmit an electrical signal to the attachment / detachment control unit 41. Even when the battery 36 a is held by the battery holding unit 36, if the voltage is not generated at the positive phase input terminal 91 by the Zener diode 76, the negative phase input voltage value V 2 is greater than the positive phase input voltage value V 1. Therefore, the comparator 76 transmits an electrical signal applied to the negative power supply voltage value VEE from the output terminal 94 to the attachment / detachment control unit 41. Accordingly, the charging unit 70 detects that power is not transmitted from the charging unit DC input unit 71, that is, the supply of power from the apparatus main body 20 to the display operation unit 30 is stopped, and detects that the supply is stopped. The locking means 42 can be controlled to the blocking state. In this way, it is possible to realize the control of the lock unit 42 based on the state detected by the supply state detection unit and the supply state detection unit by the charging unit 70.
