Description

  The present invention relates to an electronic apparatus and a program that allow key input even underwater.

  Conventionally, electronic devices that can be used not only in the air but also in water, such as underwater cameras and water depth gauges, have been provided with a push button key that can be pressed not only in the air but also in water. In order to prevent the switch from being turned on under the influence of the water pressure in the water, a biasing force that can resist the water pressure is generated using a spring having a strong elastic force. In this case, it is necessary to increase the urging force as the water depth becomes deeper. For this reason, when pressing in the air on land, the operation has to be performed with extremely large force.

  Therefore, it has been considered that it can be operated in the atmosphere and in water with the same pressing force as in the atmosphere. For example, one end of the seesaw member is pressed at the external pressure, and the other end The push button operator is pushed out to the outside by the pushing force, and the pressure and push button for pushing the manipulator to the outside are added by adding the water pressure received in water to the force pushing the push button operator to the outside. By canceling out the received water pressure, the push button can be operated with a pressing force equivalent to that in the atmosphere (see Patent Document 1).

  Further, a lower protrusion 29d is formed at the center of the disk-like elastic member 29D so that the contact operation (switching operation) can be performed satisfactorily when it comes into contact with the fixed contact 29A as will be described later.

  On the upper surface of the switch contact board 29, fixed contacts 29F, 29F,... Are formed at four locations around the doughnut-shaped fixed contact 29C. The fixed contact 29F is made of metal and has a central portion. A flat cross-shaped elastic plate member 29G that is curved toward the end is bonded and fixed with a conductive adhesive or the like so that the end thereof is in electrical contact with the fixed contact 29F.

  The plate-like elastic member 29G corresponds to the movable terminal 6B in FIG. 1, and the fixed contact 29F is electrically connected to the circuit board 31 via the wiring 29H on the upper surface of the switch contact board 29. FIG. Is input to the input terminal 2B of the central control unit 2 shown in FIG. In addition, a pair of lower protrusions 29g and 29g are provided in the vicinity of the central portion of the plate-like elastic member 29G so that the switching operation with the disk-like elastic member 29D can be performed satisfactorily.

  FIGS. 5A and 5B and FIGS. 6A and 6B show the switching operation when the operation button 23 shown in FIGS. 3 and 4 is moved in the pressing direction by a pressing operation or water pressure. It is a figure explaining.

  FIG. 5 (a) shows the state of the operation button 23 in the atmosphere (land). The protrusion 27A of the rubber member 27 has a lower surface in contact with the upper surface of the central portion of the plate-like elastic member 29G or slightly. The stopper member 28 is pushed upward by the spring members 30, 30.

  FIG. 5B shows the state of the operation button 23 when the depth meter function of the mobile phone device 1 is operated to enter the water, and the operation button 23 is pushed down by the water pressure P indicated by the arrow in the water. It is done. In the state where the water depth is still shallow, the stopper member 28 acts as a pressure-resistant stopper by the spring member 30, so that the amount of lowering of the operation button 23 is small, but when the water depth becomes deep, the operation button 23, the rubber member 27 and the The stopper member 28 descends against the spring force of the spring member 30 and further pushes down the plate-like elastic member 29G.

  As a result, when the operation button 23 moves downward by a predetermined amount, as shown in FIG. 5B, the plate-like elastic member 29G is pushed down and the lower protrusions 29g and 29g come into contact with the upper surface of the disk-like elastic member 29D. It becomes. In this case, the spring force of the spring member 30 and the disc-like elastic member 29D are such that the load from the state of FIG. 5A to the state of FIG. 5B is about 0.16 kgf (water depth of about 3 m). The elastic force is designed.

  FIG. 6A shows an upper surface of the disk-like elastic member 29D by pressing the operation button 23 with the finger 40 in the atmospheric state of FIG. 5A so that the lower protrusions 29g and 29g of the plate-like elastic member 29G are formed. The state which was made to contact is shown. In this case, since the spring force and the elastic force are designed as described above, the load by the finger 40 until contact is about 0.16 kgf.

  FIG. 6B shows a state where the plate-like elastic member 29G shown in FIG. 5B is pushed down and the lower protrusions 29g and 29g are in contact with the upper surface of the disk-like elastic member 29D. In addition, a state is shown in which the operation is performed by applying a load to the operation button 23 with the finger 40.

  In this state, the plate-like elastic member 29G is further pushed down so that the lower protrusions 29g and 29g push the disk-like elastic member 29D down and deform, and the lower protrusion 29d of the disk-like elastic member 29D is on the switch contact board 29. It comes into contact with the fixed contact 29A.

  In this case, the load of about 0.16 kgf is further applied in the state of FIG. 5B, in other words, the load of about 0.16 kgf is further applied by the finger in the state of FIG. 5B. The spring force of the spring member 30 and the elastic force of the plate-like elastic member 29G and the disk-like elastic member 29D are designed so as to be in the state 6 (b).

  As described above, the operation button 23 of the illumination key 6 includes the first key input switch that receives the switch input by contacting the plate-like elastic member 29G (6B) and the disk-like elastic member 29D (6A), and the circular key. The plate-like elastic member 29D (6A) and the fixed contact 29A (6C) are in contact with each other to form a two-stage switch structure including a second key input switch that performs switch input. Is designed so that a load of about 0.16 kgf is required, and an input of the second key input switch requires a further load of about 0.16 kgf from the input state of the first switch.

  Although the detailed structure of the operation buttons other than the operation button 23 is not described, in this embodiment, the underwater operation is effective only for the illumination key 6 switch-inputted by the operation button 23. The operation buttons other than the operation button 23 are provided with only the first key input switch, and are configured to perform key input with a load of about 0.16 kgf.

  However, if the operation keys other than the illumination keys can be operated underwater, the operation buttons of those keys may have the same structure as the operation buttons 23.

  Next, the operation of the cellular phone device 1 configured as described above will be described with reference to the flowchart of FIG.

  In step S1, it is determined whether or not there is an incoming call in the call (telephone) function. If there is an incoming call, the process proceeds to step S2 to perform a call process with the caller.

  If it is not an incoming call in step S1, the process proceeds to step S3, and it is determined whether or not there is a key input (switch input) of any of the operation buttons. If there is no key input, the process returns to step S1, but if there is a key input, the process proceeds to step S4 to determine whether or not the function key is input.

  In the case of function key, that is, key input for starting or ending each function such as a schedule function, an e-mail function, a Web site browsing function, an address book function, a water depth gauge function, etc., the process proceeds to step S5 to determine whether or not the user is currently under water. To do.

  This determination is made based on the pressure value obtained from the pressure sensor 9. If the pressure sensor 9 is not underwater, the process proceeds to step S6, and a function process corresponding to each key input is performed. On the other hand, if it is determined that the subject is underwater, the process proceeds to step S7, and invalidation processing for invalidating the key input is performed.

  The invalidation process in this case is, for example, when a key input of a function key is detected, a flag etc. is set and stored, and then the key input function process is performed. , It means a process of returning (resetting) the flag to the original state.

  Accordingly, when the flag is not set even if key input is detected, the invalidation processing includes processing for returning to step S1 without performing any processing.

  If it is determined in step S4 that the key input is not a function key, the process proceeds to step S6 to determine whether or not the key input is from the movable terminal 6B which is the first switch of the operation button 23. In the case of the key input from the movable terminal 6B, this is the key input according to the state of FIG. 5B or the key input according to the state of FIG. 6A. It is determined whether or not.

  As a result of the determination, if it is underwater, as shown in FIG. 5 (b), the key input is made by the water pressure, and the key input is not intended by the user. The invalidation process (including the process of returning to step S1 without doing anything) is performed to invalidate the key input by.

  On the other hand, if it is not underwater, it is determined that the key input is performed by the user's finger 40 shown in FIG. 6A, and the process proceeds to step S11 to turn on the backlight device 5 to illuminate the display unit 3.

  In step S8, when the key input is not from the movable terminal 6B, the process proceeds to step S12, and it is determined whether or not the key input is from the fixed terminal 6C. If it is a key input from the fixed terminal 6C, the process proceeds to step S13 to determine whether it is underwater. If it is underwater, the process proceeds to step S11 to turn on the backlight 5 device.

  When it is determined in step S13 that it is not underwater, it is a case where the operation button 23 is strongly pressed in the atmosphere and a key input from the fixed terminal 6C is detected. In this case, steps S8 and S9 have already been performed. And since the process which lights the backlight apparatus 5 is performed by S11, it returns to step S1 without doing anything.

  If the key input is not from the fixed terminal 6C in step S12, the process proceeds to step S14, where it is determined that the key input is for another operation button, and processing corresponding to each key input is performed. However, even in this case, the process is not performed if it is underwater, and the process is performed only when it is not underwater.

  Thus, in the above embodiment, the illumination key 6 has a two-stage switch structure, and the load for the first-stage switch input and the load from the first-stage switch input state until the second-stage switch input is made. In the atmosphere, the backlight device 5 is turned on by the first-stage switch input, and the first-stage switch input is invalidated in the water to disable the second-stage switching input. Since the backlight device 5 is turned on, the backlight device 5 can be turned on by pressing the operation button 23 of the illumination key 6 in the air or water with the same pressing load.

  FIG. 8 shows another embodiment of the switch contact board 29 according to the present invention. In FIG. 8, the switch contact board 31 is provided with fixed contacts 32, 33 and 34. A reference voltage from the output terminal 2 </ b> A of the central control unit 2 is supplied to the fixed contact 32.

  Further, the fixed contact 33 is electrically connected to the input terminal 2B of the central control unit 2 in FIG. 1, and the fixed contact 34 is electrically connected to the input terminal 2C of the central control unit 2.

  That is, a reference voltage is supplied to the fixed contact 32, the fixed contact 33 is electrically connected to the input terminal 2B of the central control unit 2 as a first switching output, and the fixed contact 34 is connected to the central control unit as a second switching output. 2 input terminals 2C.

  A plate-like elastic member 35 is attached on the fixed contact 32. The plate-like elastic member 35 is made of metal like the plate-like elastic member 29 shown in FIG. 4A, but has a flat plate portion 35A formed on the upper surface and opposed to the fixed contact 33 on the lower surface. A protruding portion 36 is formed at a position where the protruding portion 36 is formed, and a protruding portion 37 is formed at a position facing the fixed contact 34 in the center. In addition, a pair of spring members 38 are provided with the protrusion 37 interposed therebetween.

  The length of the protruding portion 36 is longer than the protruding portion 37, and when the flat plate portion 35A of the plate-like elastic member 35 is pressed, the protruding portion 36 first contacts the fixed contact 33, and at that time, the spring member The lower end of 38 abuts on the upper surface of the switch contact board 31.

  When the flat plate portion 35A of the plate-like elastic member 35 is further pressed, the flat plate portion 35A descends against the spring force of the spring member 38 and the projecting portion 37 on the central lower surface comes into contact with the fixed contact 34.

  Therefore, the load until the flat plate portion 35A of the plate-like elastic member 35 is pressed and the protruding portion 36 comes into contact with the fixed contact 33 is about 0.16 Kgf. Further, the flat plate portion 35A is pressed and the protruding portion 37 on the center lower surface is If the load until contact with the fixed contact 34 is set to about 0.16 kgf, the backlight device 5 can be lit with a pressing force of about 0.16 kgf both in the air and in water. It is.

  As described above, according to the above embodiment, the push-type operation button 23 has a two-stage switch structure, and in the atmosphere, the backlight illumination is performed by the first-stage key input. In the water, even if there is a first-stage key input, the predetermined process is not performed, and when the second-stage key input is performed, control is performed so that the predetermined process is performed. With a simple configuration, even in the water, the predetermined processing can be performed by pressing the operation button satisfactorily by the same operation as in the atmosphere.

  Also, the control for performing a predetermined process by a first-stage key input and the control for performing a predetermined process by a second-stage key input are determined based on whether or not the device itself is in water. Therefore, it is possible to switch automatically.

  Furthermore, by making the load for the first-stage key input and the load for the second-stage key input substantially the same, predetermined processing such as backlight illumination can be performed with the same operating force as in the atmosphere even in water. Can be done.

  Furthermore, the first-stage key input uses elastic members that are spaced apart from each other and have a central portion curved upward, and the second-stage key input is performed by a fixed contact on the board. Therefore, the structure is very simple, and the design for inputting keys with a desired load is extremely easy.

  In the above embodiment, the first-stage key input switch and the second-stage key input switch have the same load. However, considering that less force is applied in water, the second-stage key input switch It is not necessary to make both of them the same weight, such as reducing the load of the input switch.

  Moreover, although the load for switch input is 0.16 kgf, this value can be changed as appropriate.

  Furthermore, in the above embodiment, only the illumination key is a two-stage switch, but other operation buttons may be a two-stage switch. That is, for the function processing required underwater, it is only necessary to set the operation button to a two-stage switch. The key may be a two-stage switch.

  Further, the structure of the two-stage switch is not limited to the above-described embodiment, and may be another structure. For example, the disk-shaped or plate-shaped elastic members 29D and 29G are not made of metal but are conductive elastic. It may be a synthetic resin, or an insulating synthetic resin provided with conductive wiring.

  Further, in the above embodiment, the pressure sensor detects whether or not the mobile phone device 1 is in water. However, other detection means such as a water drop detection sensor is provided for underwater detection. Also good.

  The present invention can be applied not only to a mobile phone device but also to various electronic devices such as an underwater camera, a depth meter, a wristwatch, and a PDA.
