Abstract

PURPOSE:To completely stop the operation of transmission means and to attain inexpensive constitution based upon mechanical constitution by providing the data input device with a stop means for stopping the operation of the transfer means. CONSTITUTION:The data input device is provided with a rotor 3 stored to be partially projected from a frame body 2 and held to be optionally rotated, transfer means 4a, 4b for transmitting the rotation of the rotor 3 to detection parts 5a, 5b and the stop means 20 for stopping the operation of the means 4a, 4b. When a stop button 8 is depressed, a lock gear 20b is engaged with a roller gear 20a to disable the gear 20a from rotating. Namely, even if shock or vibration is applied to a mouse 1 from the external and the ball 3 is rotated, the rollers 4a, 4b are not rotated, so that no electric signal is outputted from the encoders 5a, 5b. Consequently, the data input device capable of completely stopping data input which is the operation of the mouse 1 and constituting the inexpensive device based upon the mechanical constitution can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data input device, and particularly to a data input device for manually inputting data such as coordinates in a computer.

[Prior Art] A conventional data input device will be explained with reference to FIG. In the figure, 1 is a mouse as a data input device for inputting data such as coordinates in a computer, and this mouse 1 is housed in a case 2 as a housing and a part of the case 2 facing from the bottom. A ball 3 as a rotating body held rotatably and rotatably, and a movement detection roller 4 as a transmission means for transmitting the rotation of the ball 3.
a, 4b, and this movement amount detection roller 4a.

an encoder 5a that is pivotally supported on one end of the roller 4b and serves as a detection unit that converts the amount of rotation of the rollers 4a and 4b into an electrical signal;
5b, and the ball 3 is placed on the roller 4a.

4b and the encoder 5
It is composed of a code 7 that transmits the signals output from a and 5b to a higher-level device such as a computer.

Usually, the mouse 1 is used while being moved on a horizontal surface such as a desk. At this time, the ball 3 housed so as to be partially exposed from the bottom of the case 2 rotates, and this rotation is reflected by the roller 4a.
, 4b to encoders 5a and 5b, which converts it into an electrical signal and outputs it.

This mouse 1 uses an encoder 5a to measure displacement in the X direction in computer coordinates, and an encoder 5a to measure displacement in the X direction in computer coordinates.
b, and by moving it in any direction, you can move the cursor on the computer screen.

However, the ball 3 is not fixed at all and moves freely when touched by a hand or the like, so the cursor on the screen moves to a different location from the intended location, resulting in extremely poor workability. Therefore, Japanese Unexamined Patent Application Publication No. 1-103723 and Japanese Utility Model Application No. 1-96039 disclose devices in which a mechanism for stopping the operation of the mouse 1 is provided. Figures 3 and 4 are external perspective views and partial sectional views showing a mouse equipped with a slip prevention member, and Figures 5 and 6 are a plan view and front sectional view showing a mouse equipped with a ball stopping pad. It is.

First, in the mouse IA shown in FIGS. 3 and 4, 8
10 is a stop button with a latch mechanism, 10 is a slip stopper member, 11 is an operating arm, 12° 14 is a rack gear, 1
3 is a pinion gear, and 15 is a return spring. The stop button 8 is in a pressed state and the anti-slip member 10 is retracted from the bottom surface 2a of the case 2, so the ball 3 can rotate in contact with a horizontal surface such as a desk.

When the stop button 8 is pressed, the operating arm 11 returns due to the action of the return spring 15, and the anti-slip member 10 protrudes from the bottom surface 2a of the case 2 via the rack gear 12.degree. 14 and the pinion gear 13. That is, the ball 3 rises from the horizontal surface and does not move, so the mouse I
The operation of A can be stopped. Cancellation is performed by pressing the stop button 8 again.

In addition, in the mouse IB shown in FIGS. 5 and 6, 1
Reference numeral 6 denotes a ball stop pad that presses the ball 3 in conjunction with the stop button 8. Since the pad 16 presses the ball 3 so that it does not move when the stop button 8 is pressed, the operation of the mouse IB can be stopped.

Cancelation is similarly performed by pressing the stop button 8 again.

[Problem to be solved by the invention] The conventional data input device is configured as described above.
Due to external impact force or vibration.

Ball 3 rotates, ball 3 and roller 4a.

A slip occurs between the roller 4a and the roller 4b.

Since the mouse 4b rotates and electrical signals are output from the encoders 5a and 5b, it is not possible to completely stop inputting data, which is the operation of the mouse 1.

Furthermore, if data input is stopped electrically, the control becomes complicated and the device becomes expensive.

This invention was made in order to solve the above-mentioned problems, and it is possible to completely stop data input by mouse movement, and to input data that can be constructed at low cost using a mechanical mechanism. The purpose is to obtain an input device.

[Means for Solving the Problems] A data input device according to the present invention includes a rotating body that is housed so that a part thereof faces from a housing and is rotatably held, and a detection unit that detects the rotation of the rotating body. The transmission means includes a transmission means for transmitting a signal to the transmission means, and a stop means for stopping the operation of the transmission means.

[Operation] The data input device of the present invention includes a transmission means for transmitting the rotation of a rotatable body rotatably held to a detection unit,
By providing the stop means for stopping the operation of the transmission means, the rotation of the rotating body is not transmitted to the detection section.
゛[Example] Hereinafter, a data input device which is an example of the present invention will be described as a first example.
This will be explained using figures. Components that are the same as those in FIGS. 2 to 6 are designated by the same reference numerals, and the description thereof will be omitted. In the figure,
20a is a stop roller gear pivotally supported on the other end side of the rollers 4a and 4b, and 20b is a lock gear that is interlocked with the stop button 8 and is provided so as not to rotate. A stopping means 20 is constituted by the roller gear 20a, the lock gear 20b, and the stopping button 8 having a latch mechanism.

In the above configuration, when the stop button 8 is pressed, the lock gear 20b meshes with the roller gear 20a. However, since the lock gear 20b is not rotatable, the roller gear 20a is also not rotatable. That is, even if impact force or vibration is applied to the mouse 1 from the outside and the ball 3 rotates, the roller 4a.

Since the mouse 4b does not rotate, no electrical signals are output from the encoders 5a and 5b, and data input, which is the operation of the mouse 1, can be completely stopped. Note that since the rollers 5a and 5b are made unrotatable by the meshing of the gears, it is possible to completely stop the operation due to slippage between the stop means. Furthermore, since the stopping means 20 is a mechanical mechanism, it is inexpensive.

In this embodiment, the rollers 4a and 4b are stopped by a stopping means 20 consisting of a roller gear 20a and a lock gear 20b.
Although it is assumed that the rollers 4a and 4b are not rotatable, the present invention is not limited thereto, and the same effect can be obtained even if the rollers 4a and 4b are stopped by being pressed with a pad.

[Effects of the Invention] As described above, according to the present invention, since the data input device is provided with a stop means for stopping the operation of the transmission means, the rotation of the rotating body is not transmitted to the detection unit, and the operation is completely stopped. It is possible to stop the motor, and since the above-mentioned stopping means is constituted by a mechanical mechanism, it is inexpensive.
