Claim 3

A learning remote control device of a type capable of receiving and storing a remote-controlled signal from a to-be-­learned remote control device and of reproducing the stored remote-controlled signal for transmission, which device is operable in such a manner that a remote-controlled signal received in correspondence with a first key manipulation of the to-be-learned remote control device and a remote-control­led signal received in correspondence with a second key manipulation of the to-be-learned remote control device are compared during a storage mode in which the remote-controlled signal can be stored, and such remote-controlled signal can be stored in the event that said remote-controlled signal re­ceived in correspondence with the first key manipulation of the to-be-learned remote control device and said remote-­controlled signal received in correspondence with the second key manipulation of the to-be-learned remote control device coincide with each other, said learning remote control device comprising: a determining means operable to determine whether or not it is aremote-controlled signal of a format wherein the code of a particular bit varies each time the key is operated, by referring to both of said remote-controlled signal received in correspondence with the first key manipula­tion of the to-be-learned remote control device and said remote-controlled signal received in correspondence with the second key manipulation of the to-be-learned remote control device in the event that said remote-controlled signal receiv­ed in correspondence with the first key manipulation of the to-be-learned remote control device and said remote-controlled signal received in correspondence with the second key manipu­lation of the to-be-learned remote control device do not coincide with each other, whereby, in the event that the remote-controlled signal is of a type wherein the code of particular bit varies, the remote-controlled signal corres­ponding to such type is stored on the basis of an output from said determining means.

Claim 4

A learning remote control device of a type capable of receiving and storing a remote-controlled signal from a to-be-­learned remote control device and of reproducing the stored remote-controlled signal for transmission, which device is operable in such a manner that a remote-controlled signal received in correspondence with a first key manipulation of the to-be-learned remote control device and a remote-control­led signal received in correspondence with a second key manipulation of the to-be-learned remote control device are compared during a storage mode in which the remote-controlled signal can be stored, and such remote-controlled signal can be stored in the event that said remote-controlled signal re­ceived in correspondence with the first key manipulation of the to-be-learned remote control device and said remote-­controlled signal received in correspondence with the second key manipulation of the to-be-learned remote control device coincide with each other, said learning remote control device comprising: a determining means operable to determine whether or not it is aremote-controlled signal of a format wherein the code of a particular bit varies each time the key is operated, by referring to both of said remote-controlled signal received in correspondence with the first key manipula­tion of the to-be-learned remote control device and said remote-controlled signal received in correspondence with the second key manipulation of the to-be-learned remote control device in the event that said remote-controlled signal receiv­ed in correspondence with the first key manipulation of the to-be-learned remote control device and said remote-controlled signal received in correspondence with the second key manipu­lation of the to-be-learned remote control device do not coincide with each other, whereby, in the event that the remote-controlled signal is of a type wherein the code of particular bit varies, the remote-controlled signal corres­ponding to such type is stored on the basis of an output from said determining means.

Claim 5

A learning remote control device capable of receiving a remote-controlled signal of a type wherein a remote-­controlled code of particular bit reverses each time a key is manipulated, categorizing the remote-controlled signal into a plurality of category data, storing them as a category number data in a memory and of reproducing and transmitting the remote-controlled signal on the basis of the category number data read out from the memory, said learning remote control device comprising: a storage means in which a category data providing a reference for the categorization of said remote-controlled signal is stored; a converting means for categorizing the received remote-­controlled signal according to the category data in the storage means to provide category number data; a reversed category number data formulating means for formulating reversed category number data, wherein a particu­lar bit of the category number data has been reversed, on the basis of the category number data which have been converted by the converting means; and a comparing means for comparing a reversed category number data, corresponding to the remote-controlled signal received in correspondence with the first manipulation of a key during a storage mode in which the remote-controlled signal can be stored, and a category number data, correspond­ing to the remote-controlled signal received in correspondence with the second manipulation of a key, with each other; wherein, when the reversed category number data corres­ponding to the first manipulation of the key and the category number data corresponding to the second manipulation of the key coincide with each other, the category number data can be stored in the memory in response to an output from the comparing means.

Claim 6

A learning remote control device capable of receiving a remote-controlled signal of a type wherein a remote-­controlled code of particular bit reverses each time a key is manipulated, categorizing the remote-controlled signal into a plurality of category data, storing them as a category number data in a memory and of reproducing and transmitting the remote-controlled signal on the basis of the category number data read out from the memory, said learning remote control device comprising: a storage means in which a category data providing a reference for the categorization of said remote-controlled signal is stored; a converting means for categorizing the received remote-­controlled signal according to the category data in the storage means to provide category number data; a reversed category number data formulating means for formulating reversed category number data, wherein a particu­lar bit of the category number data has been reversed, on the basis of the category number data which have been converted by the converting means; and a comparing means for comparing a reversed category number data, corresponding to the remote-controlled signal received in correspondence with the first manipulation of a key during a storage mode in which the remote-controlled signal can be stored, and a category number data, correspond­ing to the remote-controlled signal received in correspondence with the second manipulation of a key, with each other; wherein, when the reversed category number data corres­ponding to the first manipulation of the key and the category number data corresponding to the second manipulation of the key coincide with each other, the category number data can be stored in the memory in response to an output from the comparing means.
