Abstract
Abstract In a portable dialing unit dial data inputted through a keyboard are registered in an internal memory. When desired dial data is retrieved from the registered dial data and a dial key is pressed, the retrieved dial data is converted to corresponding tone signals and supplied to a speaker. The speaker outputs corresponding tones. A portable automatic dialing unit is acoustically coupled to a mouthpiece of a telephone set. The tones outputted from the speaker are again converted to tone signals by the telephone set, and transmitted to a telephone line. A switchboard is driven by the tone signals. The unit includes two modes: The first mode includes registered target numbers and the second mode includes data for special telephone service. The target number in the first mode can be inserted into any position of the data in the second mode.
