Abstract

PURPOSE:To improve the operability by providing a slide member sliding vertically to the side face of a transceiver and depressing the slide member so as to be slided thereby raising up-command. CONSTITUTION:In depressing a slide plate 27 toward the side face of a case 1, an unlock contact 26b provided to a guide chip 31 and an unlock contact 26a provided to a support member 30 are closed to generate an unlock command. On the other hand, when the slide plate 27 is depressed at a position slide upward, the unlock contacts 26b, 26a are closed, a pulse is sent from a pulse generator 7 to an up-down counter 8 to count up and its output is sent as the up command. Further, when the plate 27 is pushed down while the plate 27 is slided downward, a pulse is sent from the pulse generator 7 to the up-down counter 8 to attain count down and its output is sent as the down command. In detaching the depression, the plate is restored automatically to the center position by a spring 32.

The channel selection member 12 is equipped with a thumbwheel 24t - the rotational position of the thumbwheel 24 is 6x.
There is also a method of sending the signal to the pulse deenerator 7 via the -x' connection. Another method using a rotating body as a channel selection member is a dial system with an undefined position. The above-mentioned up button 121 and down button 13 distinguish between slow scan and rapid scan based on the time element of pressing, and since there are two operating members, the operability is poor and it is difficult to stop at the desired channel. It has certain drawbacks. Further, if the operating member is touched carelessly, the up/down counter may malfunction, so a lock button must be provided in addition to the up chain 12 and down button 13.
