Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cursor key device used for moving a cursor on a display screen.

[0002]

[Prior Art]

 As is well known, this type of cursor key device is used in game machines. Conventionally, there is known a cursor key device having a cursor key, four rubber contacts, and eight fixed contacts. In this cursor key device, the cursor key is swung against the elastic force of the rubber contact to bring the rubber contact into contact with the fixed contact, and the elastic force of the rubber contact causes the cursor key to move to its original position. Returned to position.

[0003]

[Problems to be solved by the device]

 However, in the conventional cursor key device, since the cursor key is restored by the elastic force of the four rubber contact points, the restoring force of the cursor key differs depending on the swinging direction of the cursor key. There is a problem.

An object of the present invention is to provide a cursor key device which can make the restoring force of the cursor key uniform even when the cursor key is swung in any direction.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a cursor key device used for moving a cursor on a display screen, a supporting rod fixed to a substrate and having a tip end formed in a substantially hemispherical shape. An annular movable receiving member that is movably fitted to an intermediate portion of the support rod, and is elastically attached between the movable receiving member and the substrate in a direction separating the movable receiving member from the substrate. An elastic member for urging, and a recessed portion in the center, the recessed portion being fitted to the projecting end portion of the support rod, and being supported by the movable receiving member, a substantially disk-shaped cursor key. A cursor key device is obtained.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 illustrates a pocket computer having a cursor key device according to an embodiment of the present invention. The illustrated pocket computer has a keyboard 10 composed of a large number of keys, a display device 20 composed of five display devices, and a cursor key device 30 according to the present invention. The main body (not shown) of the pocket computer is covered with an upper case 40 and a substrate 50 (FIG. 2). The cursor key device 30 has cursor keys 31 provided substantially in the same plane as the upper case 40. The cursor key 31 has a substantially disc shape, and a stick 31a is formed in the upper center part.

As shown in FIGS. 2 and 3, the cursor key 31 is supported by a support means 60 provided on the substrate 50 so as to be swingable around a central portion. The support means 60 is fixed to the substrate 50 and has a support bar 61 having a substantially spherical upper end, and an annular movable receiving member 62 fitted in an intermediate portion of the support bar 61 so as to be vertically movable. It comprises a spring 63 arranged between the motion receiving member 62 and the substrate 50 to elastically bias the movable receiving member 62 toward the cursor-31. A recess 31b is formed in the lower center of the cursor key 31. The cursor key 31 is mounted on the movable receiving member 62 with its recess 31b fitted to the upper end of the support rod 61. An annular conductive member 70 is fixed to the lower surface of the cursor 31. The conductive member 70 is grounded.

Referring to FIGS. 3 and 4, the substrate 50 has first to twelfth fixed contacts 32-1 to 32-12 oscillated on the substrate corresponding to the central portion of the cursor key 31. They are arranged in a clockwise order on the circumference centered on the center O 1 at predetermined intervals. That is, when the first fixed contact point 32-1 is set to the reference direction of 0 °, the second to twelfth fixed contact points 32-2 to 32-12 are rotated clockwise by 30 ° and 60 °, respectively. , 90 °, 120 °, 150 °, 180 °, 210 °, 240 °, 270 °, 300 °, 330 °. The first to twelfth fixed contacts 32-1 to 32-12 are carbon contacts. When the cursor 30 is swung by a predetermined angle in any one of the fixed contacts 32-1 to 32-12, the conductive member 70 causes the fixed contacts 32-1 to 32-12 to move. Contact with either. In this case, the fixed contact points 32-1 to 32-12 with which the conductive member 70 is in contact send a cursor movement instruction signal to the CPU (not shown). More specifically, when the first to twelfth fixed contacts 32-1 to 32-12 and the conductive member 70 come into contact with each other, the cursor is rotated clockwise by 0 °, 30 °, 60 ° and 90 °, respectively. , 120 °, 150 °, 180 °, 210 °, 240 °, 270 °, 300 °, 330 °, a movement instruction signal is sent to the CPU. The CPU moves the cursor in the direction indicated by the movement instruction signal.

As shown in FIG. 5, each of the fixed contacts 32-1 to 32-12 is composed of a pair of fixed contacts, and the pair of fixed contacts are connected by the conductive member 70. Good.

[0011]

[Effect of the device]

 The cursor key device of the present invention can make the restoring force of the cursor key uniform even when the cursor key is rocked in any direction.
