A transmitter/receiver module of cordless keyboard assembly adapted to be received and fixed inside a disk driver slot provided on the front panel of a computer casing is disclosed, including a frame sized to be received within the disk driver slot, having two lateral sides each having a slot opposite to each other for receiving a transmitter/receiver circuit module in the form of a circuit board which includes an encoder for setting the operation frequency of the transmitter/receiver circuit by means of at least one manually depressible button provided on the circuit module. The circuit module also has a display for showing the operation frequency thereof. A cover lid made of a material through which the signal from/toward the transmitter/receiver circuit module is transmittable is provided to cover the front opening of the frame. The cover lid is provided with an opening for access to the depessible button and observation of the display. The frame has a resilient catch provided on each of the two lateral sides thereof for engaging side wall of the disk driver slot for fixing the transmitter/receiver module therein.
A transmitter/receiver module of cordless keyboard assembly comprising a frame which is sized to be received within a disk driver slot formed on a front panel of a computer casing, the frame having two opposite lateral sides each having a slot opposite to each other to receive and hold therein a transmitter/receiver circuit module therein, each of the two lateral sides having a resilient catch provided thereon to respectively engage a side wall of the disk driver slot so as to hold the frame in the disk driver slot, the circuit module being connected to a computer circuit board via a control circuit which comprises an output cable having one end electrically connected to the control circuit and an opposite end electrically connected to the computer circuit board.
