Abstract

PURPOSE:To make the generation and use of another software for demonstration unnecessary, by outputting a key data in a storage part with the same interval as an input time interval or the time interval in which the input time interval is converted to a prescribed ratio, to a personal computer. CONSTITUTION:Two kinds of execution, a data registration mode and a data reproducing mode, are performed. When the data registration mode is designated, the key data outputted from a keyboard 2 is fetched in a data input part 4,and the time interval between data measured at a time setting part 8 is stored in a storage part 7 corresponding to the key data fetched simultaneously. Meanwhile, when the data reproducing mode is designated, the key data that is the content of the storage part 7 and the input time interval are inputted from a data output part 6 to the personal computer main body 3 as it is or with the time interval converted to the prescribed ratio. In such way, it is possible to make the same key operation every time in the case when the personal computer is used unnecessary, and especially to make another specific software for the sales demonstration in which the personal computer is used unnecessary.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a key operation reproduction device for inputting key data from a keyboard to a personal computer.
Used for sales demonstrations of software features.

(Prior Art) A keyboard converts a code corresponding to the content input by keystrokes into serial data, and transmits the input information to the CPU of a personal computer (hereinafter referred to as a personal computer).

(Problem to be solved by the invention) For this reason, the faster the keystroke speed, the faster the transmission speed, but in general, it is limited by the keystroke speed of the key operator, and moreover, the same keystrokes are repeated every time the computer is used. There is a need to do. Further, when performing a sales demonstration of software such as business software, key operations are complicated, so it is necessary to separately create and use demonstration software.

(Means for Solving the Problems) The key operation reproduction device of the present invention is a device that is connected to a keyboard and a personal computer via an intermediary, and outputs an output in response to a keystroke of *a from the keyboard. a data input section that takes in key data, a time measurement section that measures input time intervals between key data, a storage section that stores key data and input time intervals in association with each other, and inputs the key data in the storage section. and a data output unit that outputs data to the personal computer at the same intervals as the input time intervals or at time intervals obtained by converting the input time intervals to a predetermined ratio.

(Function) The key operation reproduction device executes two modes: data registration mode and data reproduction mode. When the data registration mode is specified, the key data output from the keyboard is imported into the data input section, and the time interval between the data measured in the time setting section is stored in the storage section in correspondence with the key data that is simultaneously captured. Ru. On the other hand, when the data reproduction mode is specified, the key data and input time interval, which are the contents of the storage section, are inputted from the data output section to the personal computer main body, either as they are or at a time interval converted to a predetermined ratio.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a key operation reproduction device according to the present invention.

This key operation reproduction device l is in a mode for registering serial data input from the keyboard 2 (data registration mode).
This device is capable of operating in two modes: and a mode (data reproduction mode) in which key data once registered is sent to the personal computer body 3 as serial data.

Serial data output from the keyboard 2 is taken in from the key data input section 4, and this data is output as serial data from the key data output section 6 via the control section 5 to the personal computer main body 3, as well as the control section 5. The data is stored in the storage unit 7 in accordance with the command. At this time, at the same time, the timer part 8 is activated in response to a command from the control section 5 to measure the input time interval of key data and output it to the control section 5. The timer part 8 has a function of counting the reference clock, and uses an external crystal oscillator (
(not shown) provides this reference clock.

Then, appropriate frequency division is performed using hardware or software to create a count base time. For example, if the oscillation frequency of the crystal oscillator is 6MHz, for example, 1
A count base time with 0 m5ec as one cycle is created, and the number of times this count base time is counted is stored in the storage unit 7 as 2-byte input time interval data.

Therefore, the time reproduction resolution is correctly reproduced at 1Qmsec up to a time that is 216 times 10m5ec, but any time longer than this is registered as, for example, the maximum value of 655 seconds. On the other hand, in the data reproduction mode, in addition to the mode (real mode) in which data is sent out based on the input time interval, there is also a mode (high speed mode) in which data is sent out based on the value of input time interval data to 1. Streets are selectable. Of course, the count base time is 10IllS
If you perform the above operation from eC to l m5ec, the maximum reproduction time is 18. (65.5 seconds), but the time reproduction resolution can be accurately reproduced up to 1 m5ec.

That is, when the output from the keyboard 2 is taken into the key data input section 4, the control section 5 takes in the timer value of the timer part 8, and uses this timer value as input time interval data next to the previous key data. At the same time, the current key data is saved in order to measure the time interval with the next key data, and the timer part 8 is started. Thereafter, the same operation is repeated, and the serial data sent from the keyboard 2 and the input time interval are registered in the storage unit 7 in association with each other. In this way, for example, if n times of key operations are performed on the keyboard 2, if the time interval data is stored as 2-byte data, 3n-2 data will be stored.

In FIG. 2, D T r indicates the contents of the first input key data, and the input time interval between this data and the next key data D T z is TM.

Similarly, the manual time interval between key data DT2 and the next key data is TM. TM.

is the time data up to the time when registration mode was canceled, but this data will be cut. This storage unit 7 uses a nonvolatile memory or a memory that can be backed up by a battery or the like.

Next, when reproducing data stored in the storage unit 7, the operation when so-called data reproduction mode is specified will be described.

Switching from the data registration mode to the data reproduction mode described above is performed by operating the mode setting section 9. The control section 5 reads the mode set by the mode setting section 9 and outputs the data stored in the storage section 7 to the key data output section 6. At this time, in addition to outputting the data to have the same data output interval as the time interval of the input data, it is also possible to convert the input time interval to a predetermined ratio, e.g., multiply the data time interval by 18 times. This allows the key data to be expanded onto the personal computer main body 3 at high speed. Further, the mode setting section 9 is capable of setting a repeat mode, and when this mode is specified, the registered data is repeatedly output to the personal computer body 3. The status display unit 10 not only displays the currently executed mode, ie, data registration mode or data reproduction mode, but also displays a buffer full status at the time of registration.

Note that the storage unit 7 can not only store one type of data, but also multiple types of series of data,
Necessary data among these can be specified from the mode setting section 9.

In addition, most of the key operation reproduction device in this example can be integrated into one chip, which reduces the number of component parts.
Since power consumption can be reduced, operation is possible with power supplied from the personal computer body 3.

(Effects of the Invention) As described above, according to the present invention, it is no longer necessary to perform the same key operations every time a personal computer is used. In particular, there is no need to create special demo software when demonstrating sales of software (functions) using a personal computer.
