Claim 11

An input apparatus comprising: keyboard means; buffer means for storing at every unit time a plurality of key codes, each key code corresponding to a continuously depressed key of said keyboard means; output means for sequentially outputting the key codes stored in said buffer means; and control means for immediately clearing all of the key codes remaining in said buffer means when said continuously depressed key is released after a predetermined period and, when all of the remaining key codes stored in said buffer means are the same, such that sequential output of the remaining key codes stored in said buffer means is inhibited.

Claim 12

An input apparatus according to claim 8, wherein said input apparatus is a keyboard of an electronic typewriter.

Claim 13

An input apparatus according to claim 8, wherein said buffer means also stores the key codes for a key intermittently depressed.

Claim 14

An input apparatus comprising: keyboard means; buffer means for sequentially storing a plurality of key codes, each key code corresponding to a continuously depressed key of said keyboard means; output means for sequentially outputting the key codes stored in said buffer means; and control means for immediately clearing said buffer means, wherein said control means is responsive to said input means and clears all of the key codes remaining in said buffer means when the input of key codes for said continuously depressed key is terminated after a predetermined period, and when all of the remaining key codes are the same, such that sequential output of the remaining key codes stored in said buffer means is inhibited.

Claim 15

An input apparatus comprising: keyboard means; buffer means for sequentially storing a plurality of key codes, each key code corresponding to a continuously depressed key of said keyboard means; output means for sequentially outputting the key codes stored in said buffer means; and control means for immediately clearing said buffer means, wherein said control means is responsive to said input means and clears all of the key codes remaining in said buffer means when the input of key codes for said continuously depressed key is terminated after a predetermined period, and when all of the remaining key codes are the same, such that sequential output of the remaining key codes stored in said buffer means is inhibited.

Claim 16

An input apparatus according to claim 11, wherein said control means processes in accordance with the key code outputted from said output means.

Claim 17

An input apparatus according to claim 11, wherein said input apparatus is connected to a printer and a display.

Claim 18

An input apparatus according to claim 11, wherein said input apparatus is connected to a printer.

Claim 19

An input apparatus according to claim 11, wherein said input apparatus is connected to a display.

Claim 20

Apparatus comprising: key means manually depressed to enter a processing code into the apparatus; buffer means for detecting at each predetermined interval whether or not said key means is being continuously depressed and for storing the processing code in response to each detection of the depression of said key means, the buffer means sequentially storing a plurality of processing codes; and control means for accessing said buffer means to execute a processing operation designated by an accessed one of the processing codes stored in said buffer means, each stored processing code in said buffer means being sequentially cleared upon execution, whereby the same processing is repeatedly executed during the continuous depression of said key means ovver said predetermined interval, and wherein said control means, in response to the release of the continuously depressed key means, detects whether or not all of the remaining unexecuted processing codes stored in said buffer means are the same, and immediately clears all the remaining unexecuted processing codes in said buffer means when all the remaining unexecuted processing codes are the same, such that sequential execution of the processing remaining unexecuted codes stored in said buffer means is inhibited.
