| 摘要 |
The invention relates to a device for forming a digital code intended to control access to a protected area, including a device (11) for comparing the code entered with a predetermined code, the said comparison device allowing access to the said protected area in the event of agreement between the said codes, characterised in that it includes at least one repeated-action key (1-4), a device (7-10) for detecting the number of successive actuations associated with the said key and supplying a figure corresponding to the number of actuations of the corresponding key. Advantageously, this device for forming a digital code with several figures is characterised in that it includes a number of repeated-action keys (1-4) equal to the number of figures of the digital code, the said repeated-action keys (1-4) being actuated successively.
