Description

  The present invention relates to a mouse as an input device in an information processing apparatus such as a personal computer.

  Conventionally, for example, various control target devices such as production facilities have generally introduced automatic control by a sequencer, but recently, with the widespread use of various digital devices, application programs on personal computers There are an increasing number of ways to operate and control the system.

  For example, in a control system or the like, a symbol on the screen of a display device in a personal computer is operated by moving the mouse, pointing with the pointer, and clicking with the left button switch of the mouse to start or stop the control target device There are many uses like this.

As this type of mouse, an operation opening is formed on the upper surface of the main body case so as to face the movement amount detection ball, and a finger is inserted through the operation opening to rotate the ball slightly, so that a desired screen on the screen can be obtained. A mouse is known in which the pointer can be accurately positioned with respect to the position (see Patent Document 1).
Japanese Patent Laid-Open No. 6-230893

  By the way, in the production site where the mouse is operated as described above, the operator inadvertently touches the left and right buttons of the mouse after performing an input operation, for example, a click operation, or is in the vicinity of the mouse. Documents that have been placed may fall down and touch the left and right buttons of the mouse carelessly.

  In this case, an unintended input operation signal is sent to the personal computer, and various troubles such as a malfunction of the control target device occur.

  With the above-described conventional mouse, it is only possible to accurately position the pointer by slightly rotating the movement amount detection ball with a finger, and it is impossible to prevent unintended operation input as described above.

  As an extreme measure when the above situation occurs, for example, only when an input operation is performed with a mouse, the input cable of the mouse is inserted into the connector on the personal computer main body side, and the operation is completed. It may be possible to leave the mark unplugged.

  However, with a USB mouse that is frequently used recently, when a USB input cable is inserted into the personal computer body side, a waiting time of several seconds or more is required for resetting. This cannot be adopted. Furthermore, there is no guarantee against frequent insertion and removal of the USB input cable.

  As another countermeasure, for example, a selector for switching and using one mouse for a plurality of personal computers is introduced, and the mouse is disconnected from the personal computer by the selector every time an input operation with the mouse is completed. A method of switching to the side can also be considered. However, with this method, if the selector switching is forgotten, the same problem as described above will still be caused.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a mouse that can reliably prevent an unintended operation input or the like.

  In order to achieve the above object, the present invention provides the following means.

[1] An input operation switch provided on the mouse body,
An open / close switch provided in an operation switch circuit having the input operation switch,
The mouse, wherein the open / close switch is electrically connected to the input operation switch in the operation switch circuit.

  [2] The mouse according to [1], wherein the open / close switch is provided in an attachment separate from the mouse main body.

  According to the invention of [1], if the input operation switch is turned on while the open / close switch is turned on, the input operation switch is electrically connected to the corresponding operation switch circuit. An operation signal from the operation switch is transmitted as usual.

  After the input by the input operation switch is completed, if the opening / closing switch is turned OFF, the input operation switch is electrically separated from the corresponding operation switch circuit. For this reason, when the input operation switch is not operated, for example, even if a stationery on the desk accidentally hits the button of the input operation switch, an input signal by the input operation switch is not transmitted, and therefore the control target Equipment malfunctions can be reliably prevented.

  In the invention of [2], since the open / close switch is provided in an attachment separate from the mouse main body, the open / close switch is operated by mistake when operating the input operation switch etc. of the mouse main body. Can be avoided. In other words, for example, the open / close switch of the attachment can be operated with the left hand, while the input operation switch of the mouse main body can be operated with the right hand, so that erroneous operation of both switches can be sufficiently prevented.

  FIG. 1 is a plan view showing a personal computer (hereinafter referred to as “PC”) in which a mouse 3 according to an embodiment of the present invention is used, and FIG. 2 is a circuit configuration diagram of the mouse 3.

  1 and 2, the PC includes a PC main body 1, a display device 2, and a mouse 3.

  The PC main body 1 has a mother board, a hard disk device (HDD), a CD / ROM, and the like (not shown), and operates various application information installed in the HDD or controls controlled devices. Is configured to do.

  The display device 2 is an output device of the PC main body 1 and displays, for example, a work status during operation of the application program on a screen, and includes, for example, an LCD (liquid crystal display device).

  In addition to the mouse body 4, the mouse 3 includes an appendage 5 that is separate from the mouse body 4 (see FIG. 1).

  The mouse body 4 is the same as a general mouse structure. That is, in the main body case 41 of the mouse main body 4, the left and right button switches 43 and 44 as an input operation switch and a microcomputer (microcomputer) 45 are provided in addition to a mechanical or optical position detection unit 42. The mouse main body 4 and the PC main body 1 are electrically connected by, for example, a USB cable 400.

  A left button 431 for operating the left button switch 43, a right button 441 for operating the right button switch 44, and a scroll wheel 46 are disposed on the upper surface of the body case 41 in the mouse body 4.

  The position detection unit 42 detects a two-dimensional direction movement amount by an encoder or the like when the operator moves the mouse main body unit 4 on a mounting surface such as a mouse pad.

  The left button switch 43 includes a pair of fixed contacts 43a and 43b inserted in the operation switch circuit 430 and a movable contact piece that electrically opens and closes between the fixed contacts 43a and 43b in response to the operation of the left button 431. 43c and a movable contact piece return spring member (not shown), and is used as a one-click click or a double-click double click at a specific location on the screen.

  The right button switch 44 includes a pair of fixed contacts 44a and 44b inserted in the operation switch circuit 440 and a movable contact piece that electrically opens and closes between the fixed contacts 44a and 44b in response to the operation of the right button 441. 44c and a movable contact piece returning spring member (not shown) are used for right-clicking.

  The microcomputer 45 generates a signal for sending the output from the position detection unit 42 and the outputs from the left and right button switches 43 and 44 to the PC main body 1 side.

  An opening / closing switch 52 is disposed inside the main body case 51 of the attachment 5, and a push button 511 for operating the opening / closing switch 52 is mounted on the upper surface of the main body case 51.

  The open / close switch 52 electrically connects the left button switch 43 to the operation switch circuit 430 including the left button switch 43 among the input operation switches (namely, left and right button switches) 43 and 44 in the mouse body 4. It connects so that separation is possible. Therefore, when the left button switch 43 is operated and clicked, the opening / closing switch 52 is turned ON (closed) by pressing the push button 511.

  The open / close switch 52 is electrically connected between the fixed contacts 52a and 52b disposed in the body case 51 of the appendage 5 and the fixed contacts 52a and 52b in response to the pressing operation of the push button 511, for example. It comprises a moment action type (make contact type: normally open type) push button switch including a movable contact piece 52c that opens and closes and a movable contact piece return spring member (not shown).

  The open / close switch 52 is connected to an operation switch circuit 430 on the mouse body 4 side via a cable 500.

  The open / close switch 52 is connected in series to the left button switch 43. If the contact logic (make or break) of the left button switch 43 differs depending on the type of mouse, the open / close switch of the corresponding contact logic is used. 52 may be introduced to change the connection relationship.

  Next, the procedure for using the mouse 3 will be described.

  When the operator grasps the body case 41 of the mouse body 4 placed on a placement surface such as a mouse pad with, for example, the right hand and moves and operates while viewing the screen of the display device 2, the two-dimensional of the mouse body 4 is displayed. Since each movement amount in the direction is detected by the position detection unit 42 and a movement amount detection signal is sent to the PC main body 1 side via the microcomputer 45, the pointer on the screen is moved to a predetermined position to be instructed. Can do.

  When the operator presses the right button 441, the right button switch 44 is turned ON, and a right click signal as an input operation signal is sent to the PC main body 1 side via the microcomputer 45.

  Here, when the operator wants to operate the left button switch 43, the user holds the main body case 51 of the appendage 5 with the left hand and pushes down the push button 511 with a finger to turn on the open / close switch 52.

  If the left button 43 on the mouse body 4 is pressed with the right hand while the open / close switch 52 is in the ON state, the left button switch 43 is turned on, and a click signal as an input operation signal is sent via the microcomputer 45 to the PC body 1. The processing operation corresponding to the position indicated by the pointer is performed.

  As soon as the click operation by the left button switch 43 is completed, the operator releases the left hand from the appendage 5, the push button 511 is restored, and the open / close switch 52 is turned off. When the open / close switch 52 is turned off in this way, the left button switch 43 is released from the operation switch circuit 430, so that the operation output by the left button switch 43 becomes impossible.

  Therefore, after the click operation by the left button switch 43 is completed, even if a stationery or the like on the desk, for example, accidentally hits the left button switch 43, the operation output is sent to the PC main body 1 side by the left button switch 43. Therefore, the possibility of causing the malfunction of the control target device is eliminated.

  The opening / closing switch 52 is not particularly limited to a moment-type switch, but if a moment-type push button switch such as this example is employed, the left button switch can be removed by releasing the hand from the push button 511. 43 can be immediately electrically disconnected from the operation switch circuit 430.

  Further, since the left button switch 43 is separated from the operation switch circuit 430 when the open / close switch 52 is turned off, the cable 400 of the mouse main body 4 is used while being connected to the connector 11 of the PC main body 1. The next use of the left button switch 43 can be performed quickly and without problems.

  In the above embodiment, the left button switch 43 is detachably connected to the operation switch circuit 430 by the open / close switch 52, but the right button switch 44 is connected to the operation switch circuit 440 by providing the open / close switch. May be connected so as to be separable, and an open / close switch 52 may be provided corresponding to both the left and right button switches 43 and 44.

  It is also possible to provide the opening / closing switch 52 on the mouse body 4 side. However, if the opening / closing switch 52 is provided on the attachment 5 separate from the mouse body 4 side as in this example, both Therefore, there is an advantage that it is possible to surely avoid that the input operation in the mouse body 4 and the operation of the open / close switch 52 interfere with each other and cause an erroneous operation.

  In addition, it is also possible to employ a configuration in which all operation inputs can be prohibited by providing a toggle switch or the like in addition to the opening / closing switch 52 in the appendage 5.
